"Inhibitory effects of antagonistic bacteria inhabiting the rhizosphere of the sugarbeet plants, on Cercospora beticola Sacc., the causal agent of Cercospora leaf spot disease on sugarbeet."

AbstractIn the present study, the antagonistic capability of bacterial agents inhabiting the rhizosphere of sugarbeet plants were evaluated against Cercospora beticola Sacc. under laboratory and greenhouse conditions. After preliminary screening using the dual culture method, 14 strains with higher antagonistic capability were selected for further inhibitory assays against C. beticola. Bacterial strains were identified based on the sequence data of the small subunit-rDNA (SSU-rDNA) gene. Based on the SSU sequence data, the identity of bacterial strains were determined as Bacillus (10 strains: RB1, RB2, RB3, RB4, RB5, RB6, RB7, RB8, RB9, RB10), Paenibacillus (two strains: RP1, RP2), Enterobacter (one strain: RE), and Pseudomonas (one strain: RPs). The results obtained in this study showed that in all of the assays (dual culture, volatile and non-volatile metabolites) bacterial antagonists significantly inhibited the growth of C. beticola compared to the control. Bacillus (RB2) showed the highest inhibition rate on C. beticola in all of the assays. Based on the results of the laboratory assays, three bacterial strains RB2 (Bacillus), RPs (Pseudomonas), and RE (Paenibacillus) were selected for greenhouse assays. The experiment was designed based on a completely randomised design (CRD) with the application of antagonists prior to, simultaneously, and after inoculation with C. beticola on sugarbeet leaves. The reduction in disease severity was evaluated seven days after inoculation. The results of greenhouse assays were consistent with the results of laboratory studies. The obtained results showed that bacterial antagonists significantly reduced the disease severity when compared to the control.

The influence of sucrose on the removal of Paraquat (PQT) in synthetic aqueous medium was evaluated by Phanerochaete chrysosporium. Initially, a toxicity test was performed on plates containing paraquat at concentrations of 1, 5, 10, 20 and 30 mg.L-1. Then, they were carried out in batches - agitated batch (RBA) and sequential batch (RBS). Four reactors were submitted, containing medium with 30 mg.L-1 of paraquat, under a reaction time of 144 h, the reactors being RBA-2 and RBS-2 with the addition of 2 gL-1 of sucrose, and without the adding sucrose to the RBA-0 and RBS-0 reactors. In all reactors, paraquat was removed, but in RBS-0, the best mean removal efficiency was obtained (41.1 ± 0.89%). The best values of apparent speed of degradation (k) were found in reactors with sucrose RBA-2 and RBS-2, 0.015 ± 0.002 h-1 and 0.018 ± 0.002 h-1, respectively, indicating that the addition of sucrose influenced the speed removal of paraquat. It was also verified that the pollutant was not completely removed by adsorption to fungal biomass, which microorganisms predominated in the medium at the end of the treatment, demonstrating their role in the paraquat bioremediation process. Therefore, the addition of sucrose influenced the removal speed of the PQT and COD, but not the removal efficiency.

ABSTRACT Mouse mammary tumor virus (MMTV) is a betaretrovirus that infects rodent cells and uses mouse transferrin receptor 1 for cell entry. To characterize the interaction of MMTV with its receptor, we aligned the MMTV envelope surface (SU) protein with that of Friend murine leukemia virus (F-MLV) and identified a putative receptor-binding domain (RBD) that included a receptor binding sequence (RBS) of five amino acids and a heparin-binding domain (HBD). Mutation of the HBD reduced virus infectivity, and soluble heparan sulfate blocked infection of cells by wild-type pseudovirus. Interestingly, some but not all MMTV-like elements found in primary and cultured human breast cancer cell lines, termed h-MTVs, had sequence alterations in the putative RBS. Single substitution of one of the amino acids found in an h-MTV RBS variant in the RBD of MMTV, Phe40 to Ser, did not alter species tropism but abolished both virus binding to cells and infectivity. Neutralizing anti-SU monoclonal antibodies also recognized a glutathione S-transferase fusion protein that contained the five-amino-acid RBS region from MMTV. The critical Phe40 residue is located on a surface of the MMTV RBD model that is distant from and may be structurally more rigid than the region of F-MLV RBD that contains its critical binding site residues. This suggests that, in contrast to other murine retroviruses, binding to its receptor may result in few or no changes in MMTV envelope protein conformation.

Full textAbstract:
In this article, a novel passive control system, ribbed bracing system (RBS), has been proposed to deal with the buckling problem. RBS is a bracing system with a simple mechanism that can be installed in braces as a supplemental part. The behavior of RBS is similar to that of conventional braces under tensile loading. However, under compressive force, it endures an insignificant force and prevents the braces from buckling through length reduction. In addition, seismic damage is concentrated in the bracing system of the structures equipped with RBS, decreasing the dissipated hysteretic energy in other structural members. There are two different mechanisms for RBS: 1) completely-closed RBS (CC-RBS) and 2) self-centering RBS (SC-RBS). The concept and mechanics of RBS have been verified by the results obtained from cyclic testing and numerical analysis of RBS specimens. In this research, after describing the mechanical configuration of RBS, nonlinear time history analysis has been conducted on 3-story and 6-story concentrically braced frames subjected to different seismic intensity levels, design basis earthquakes (DBE), and maximum considered earthquakes (MCE). The analyses have been performed on different types of bracing systems as follows: SC-RBS, CC-RBS, and Buckling Restrained Braces (BRB). The results show that SC-RBS frames have negligible residual story drifts, and maximum displacement in CC-RBS is slightly lower than that of BRB. Additionally, distribution of input energy into the structure was considered and showed that RBS frames demonstrate a high hysteretic energy dissipation, which results in lower demands in other structural elements.

Full textAbstract:
The study was carried out to determine and compare the toxicological effects of raw jack beans (RJB), bambara groundnuts (RBG) and benne seeds (RBS) on organs of cockerels (Goldmine strain).Full fat soya was replaced with RJB, RBG and RBS at 25% and 50% levels, respectively. One hundred and forty (140) cockerels were randomly distributed into seven dietary groups in an eight week feeding trial. Antinutritional factors such as canavanine, haemagglutinin, trypsin inhibitor, tannin and phytate contents were analyzed in the plant seeds. At the end of eighth week, the birds were killed by cervical dislocation while the internal organs were quickly dissected out. The liver, kidney, pancreas and testis were thereafter preserved in 10% formalin solution. The tissues of the organs were trimmed, fixed in Bouins fixative for 24h, embedded in wax, sectioned at 6µm with microtome and finally stained with haematoxylin and eosin for histopathological examination. The livers of the birds fed 25% RJB and 50% RJB showed extensive multifocal and lymphocytic infiltration with necrosis of hepatocytes. Moreover, the pancreas of birds fed RBG and RJB based diets showed necrosis of glandular cells, lymphoid aggregates, thickening of the supporting stroma and multifocal interstitial lymphocytic infiltration. In the testes of birds fed 25% RJB and 50% RJB, there was extensive degeneration of the seminiferous tubular epithelia cells with widespread interstitial lymphocytic infiltrations of the stroma. The liver, pancreas, kidney and testes of birds fed RBS showed moderate lesions. It is concluded in this study that RJB showed more toxicity than RBG and RBS with respect to lesions in the organs, thus depicting a severe negative effect when fed to cockerels. There is therefore the need to detoxify the raw plant seeds with a view to enhancing their nutritive value in diets of cockerels.Bang. J. Anim. Sci. 2016. 45 (2): 18-23

Full textAbstract:
Reduced Beam Section (RBS) moment connections are developed for Special Moment Resisting Frames (SMRF). According to the beam web attachment the column flange RBS connections are classified into Reduced Beam Section with Bolted web connections (RBS-B), and the Reduced Beam Section with Welded web connections (RBS-W). Beam flanges are welded to the column. Regardless of different web attachment details in RBS-B and RBS-W connections current design procedures (FEMA 350) assumes that they could develop plastic moment of the beam gross section. In current design procedures, RBS-B connections should provide the sufficient strength that can reach the plastic moment capacity of the connected beam. However, some experimental researches reported that the beams in RBS-B connections fractured before the connection reached its plastic moment capacity. Such undesirable fracture shows that RBS-B connections have less strength than RBS-W connections. And if RBS-B connections designed in current design procedures, it might fail in a brittle manner and not satisfy SMRF due to undesirable fracture. Thus, this study develops a new set of equations for accurately computing the moment strength of RBS-B connections. The proposed strength equation accurately predicts connection moment capacity for RBS-B connections.

Full textAbstract:
This paper presents a numerical study of reduced beam section (RBS) beams with vertical and horizontal stiffeners. For RBS beams, it is speculated that strength deterioration will be caused by lateral buckling and local buckling. Supplemental lateral bracing (SLB) can prevent lateral buckling but not prevent local buckling in the RBS portion. In the previous research, the effect of vertical or horizontal stiffeners in RBS portion was shown to restrain local buckling of the RBS portion. But RBS with vertical stiffeners causes stress concentration at flange, and strength of RBS with horizontal stiffeners is lower than RBS with vertical stiffeners. In this paper, various patterns of placing stiffeners at the RBS portion are presented. The effect of vertical stiffeners and horizontal stiffeners arranged at the RBS portion is discussed based on length. It is confirmed that, without placing supplemental lateral bracing (SLB), vertical and horizontal stiffeners can delay the occurrence of local buckling and prevent stress concentration. Moreover, the strength can be sustained above 0.8Mp.

Full textAbstract:
A moment connection that includes a wide flange beam with trimmed flanges is commonly known as a Reduced Beam Section (RBS) connection. Accurate analysis of frames incorporating RBS beams requires knowledge of the elastic stiffness matrix of RBS beams. In lieu of using this stiffness matrix, an RBS beam can be modeled as an Euler-Bernoulli frame element with rotational springs at each end, which can be easily implemented in structural analysis software. This paper presents the derivation of the formula for the spring constants of an RBS beam and validates it. From a study of the spring constants for a plethora of RBS beams, it was found that a strong linear relationship exists between the minimum plastic section modulus of RBS beams and their spring constants. This paper has direct applicability to the practical and accurate determination of the elastic drift of a moment frame with RBS connections.

Journal of Bacteriology 183, no. 9 (May 1, 2001): 2834–41. http://dx.doi.org/10.1128/jb.183.9.2834-2841.2001.
Full textAbstract:
ABSTRACT Twelve populations of Escherichia coli B all lostd-ribose catabolic function during 2,000 generations of evolution in glucose minimal medium. We sought to identify the population genetic processes and molecular genetic events that caused these rapid and parallel losses. Seven independent Rbs−mutants were isolated, and their competitive fitnesses were measured relative to that of their Rbs+ progenitor. These Rbs− mutants were all about 1 to 2% more fit than the progenitor. A fluctuation test revealed an unusually high rate, about 5 × 10−5 per cell generation, of mutation from Rbs+ to Rbs−, which contributed to rapid fixation. At the molecular level, the loss of ribose catabolic function involved the deletion of part or all of the ribose operon (rbs genes). The physical extent of the deletion varied between mutants, but each deletion was associated with an IS150 element located immediately upstream of therbs operon. The deletions apparently involved transposition into various locations within the rbs operon; recombination between the new IS150 copy and the one upstream of therbs operon then led to the deletion of the intervening sequence. To confirm that the beneficial fitness effect was caused by deletion of the rbs operon (and not some undetected mutation elsewhere), we used P1 transduction to restore the functionalrbs operon to two Rbs− mutants, and we constructed another Rbs− strain by gene replacement with a deletion not involving IS150. All three of these new constructs confirmed that Rbs− mutants have a competitive advantage relative to their Rbs+ counterparts in glucose minimal medium. The rapid and parallel evolutionary losses of ribose catabolic function thus involved both (i) an unusually high mutation rate, such that Rbs− mutants appeared repeatedly in all populations, and (ii) a selective advantage in glucose minimal medium that drove these mutants to fixation.

Full textAbstract:
Heritage receptive bilinguals (RBs) are individuals who report understanding but not speaking their family language. This study tests whether semantic features of functional morphemes, namely tense, aspect, and agreement markers, are accessible to them in comprehension. RBs in this study are fluent speakers of English with receptive knowledge of Labrador Inuttitut. Many RBs showed fluent-like comprehension of aspectual suffixes, subject-object-verb agreement suffixes, and past versus future contrasts in tense suffixes, but most could not identify remoteness degrees in tense suffixes. Lowest-proficiency RBs did not show knowledge of any morphemes. Remoteness features are missing from most RBs’ grammars; the same applies to many features in LRBs’ grammars. Some RBs showed inconsistent performance: better than chance, but worse than fluent speakers. The corresponding parts of RBs’ grammars are therefore fluent-like, but access to them is difficult. RBs’ grammars consist of fluent-like parts, parts with reduced access, and incomplete parts.

Introduction: Non-infectious erythema, or Red Breast Syndrome (RBS), has been observed on the skin where acellular dermal matrix was implanted, although the exact cause is yet to be determined. Patients and Methods: A total of 214 female patients underwent breast-conserving surgery (BCS) and volume replacement using diced acellular dermal matrix (dADM) for breast cancer between December 2017 and December 2018. After collecting and evaluating relevant clinical data, inflammation markers, along with NK cell status presented by IFN-γ secretion assay, were measured using ELISA. Results: Nineteen patients (8.88%) presented with RBS after BCS and dADM use. A significant increase of platelet-to-lymphocyte ratio was noted in the non-RBS group (p = 0.02). Compared to the RBS group (p = 0.042), the WBC level of the non-RBS group showed significant decrease over time. Eosinophil counts increased significantly at follow-up but went up higher in the RBS group. Multivariate analysis showed preoperative chemotherapy significantly increased the hazard of RBS (OR 3.274, p = 0.047 and OR 17.098, p < 0.001, respectively). Discussion: Though no causal relationship between RBS and immune status was proven, the results suggest an association between preoperative chemotherapy and RBS in addition to the possible role of eosinophilia in leading to eosinophilic dermatoses, which warrants further exploration and elucidation.

Background: Sealing occlusal pits and fissures is an effective preventive measure against dental caries. Pit and fissure sealants (PFS) should be strongly bonded to the teeth to prevent partial or complete loss of the sealant, which may limit its preventive effect. Objective: The objective of the study was to compare the microtensile bond strength (μTBS) of bioactive resin-based sealants (Bio-RBS) and resin-based sealants (RBS), with and without the use of a bonding agent, to the enamel of primary and permanent teeth. Methods: One hundred and twenty caries-free primary molar specimens and 120 permanent molar specimens were divided to eight groups (30 specimens per group), both primary and permanent teeth were sealed with a Bio-RBS BioCoatTM (Premier®, Plymouth Meeting, PA, USA) or with a RBS ClinproTM (3M ESPE, Saint Paul, MN, USA), with or without the use of a bonding agent (Prime & Bond NT; Dentsply, Inc., Charlotte, NC, USA). Half the specimens were aged with 5000 thermal cycles, and all specimens were tested for the μTBS and failure mode. Results: The mean μTBS of aged Bio-RBS was higher in permanent teeth than primary teeth, and the aging process reduced the μTBS of RBS more than that of Bio-RBS. Moreover, the addition of a bonding agent improved the μTBS of aged RBS in permanent teeth. Conclusion: We concluded that Bio-RBS exhibit superior μTBS than RBS when applied to permanent teeth.

Full textAbstract:
A reduced beam section with a bolted web (RBS-B) connection is permitted for use only in intermediate moment frames (IMF) according to the ANSI/AISC 358-05. This is because some RBS-B test specimens failed to achieve 4% total rotation capacity, which is the minimum story drift angle required for special moment frames (SMF). Several studies reported that some RBS-B connections could experience brittle connection fracture during earthquakes, which can also be detrimental to the seismic performance of IMF systems with RBS-B connections. For investigating whether IMFs with RBS-B connections provide a satisfactory seismic performance, this study evaluated the seismic performance of IMFs with pre-qualified RBS-B connections following the ATC-63 procedure. Twenty-four model buildings were designed according to current seismic design provisions. Several IMFs with RBS-B connections do not satisfy the acceptance criteria specified in ATC-63.

The aims of this study were to identify the status of repeat breeding syndrome (RBS) in a dairy farm, to establish the main cause of RBS and to reduce the number of RBS using the Ovsynch protocol. 20 cows were diagnosed with RBS using computer analysis of the herd and a specific diagnosis for the cause of RBS was attempted. Subsequently, they were divided into 2 groups: cows in group 1 (n=10) received no hormonal treatment while those in group 2 (n=10) were treated using the Ovsynch protocol. Artificial insemination and pregnancy diagnosis was performed in all cows. The 70% pregnancy rate obtained for Ovsynch showed that the hormonal effect as well as correct timing of insemination had a significant influence on RBS, pointing out towards the managerial factor as one of the main causes of RBS. The cow factor was also included, as endometritis, follicular cysts and anovulatory heats were diagnosed.

Full textAbstract:
Abstract The term ‘receptive bilingualism/multilingualism’ is used for diverse populations, all of which understand a language without producing speech in it, but differ in the way this receptive ability was achieved and in the linguistic knowledge underlying it. In previous studies, not enough attention is given to the differences between types of receptive bilinguals (RBs); however, a thorough analysis of all types is necessary to understand the nature of receptive bilingualism and, consequently, language comprehension and production in general. I propose a classification of RBs based on the presence and nature of an acquisition process that led to receptive abilities. In this classification, RBs who comprehend a language mutually intelligible with one they know are distinguished from RBs with acquired knowledge. Within the former, RBs with and without previous exposure are distinguished. Within acquired types, RBs who comprehend a heritage language are distinguished from RBs who comprehend a second/foreign language.

Full textAbstract:
This paper presents an analysis of the security performance and evaluation of the hardware architecture of the redundant bit security (RBS) cryptosystem. RBS is a lightweight symmetric encryption algorithm that targets resource-constrained RFID devices. Unlike the existing cryptosystems, RBS simultaneously provides confidentiality, authentication, and integrity of the plaintext by inserting hash-generated redundant bits among the already modified plaintext data. A flexible-length hash algorithm in our optimized hardware architecture allows RBS to support different key sizes which allows flexibility in the security level. Our analysis shows the resilience of RBS against powerful and well-known attacks such as differential attacks and known-plaintext attacks. We compare the performance of the RBS cryptosystem against other distinguished ciphers developed for RFID systems. Simulation results show that RBS results in approximately 100%, 239%, and 153% higher hardware efficiencies while requiring 48%, 56%, and 59% less energy-per-bit compared to H-PRESENT, HB-2, and Grain, respectively. Such results present confirmatory evidence that RBS is a superior solution for providing security in resource-constrained systems such as RFID systems especially when authentication is a priority.

Full textAbstract:
Background: Random blood sugar (RBS) is a commonly performed screening test for type 2 diabetes in both programmatic as well as clinical settings. Previous calorie intake is known to affect the results of RBS. So, present study was conducted to assess the effect of previous calorie intake on sensitivity, specificity, positive and negative predictive values (NPV) and accuracy of RBS.Methods: A cross sectional study was done in 317 patients of 30 years or more using systematic random sampling in a general outpatient department of a district hospital. All the patients underwent RBS measurement. History of calorie intake in past 1-2 hours before undergoing RBS was taken. Screening test parameters of RBS was evaluated using oral glucose tolerance test as clinical reference.Results: This study found that calorie consumption of 200 kcal or more significantly affected the screening test result of RBS. When patient had consumed 200 kcal or more in last 1-2 hours, the sensitivity of RBS is 90.0%, specificity is 57.4%, positive predictive value (PPV) is 26.9% and NPV is 97.1%. Whereas, these parameters are 63.3%. 78.5%, 43.6% and 88.9% respectively when patient had consumed less than 200 kcal in last 1-2 hours before RBS.Conclusions: Sensitivity and NPV of RBS is higher if patient had consumed more than 200 kcal 1-2 hours prior to RBS whereas specificity and PPV is higher if patient had consumed less than 200 kcal. Taking history of quantity and time of last meal would be helpful to better interpret the screening test results of RBS.

Flexural-torsional buckling of the beam in steel frame with reduced beam section (RBS) connections is analyzed. Base on the analysis of flexural-torsional buckling of the RBS beam under different loads using energy method, the critical moment calculation formula of ordinary beam is modified, and the critical moment calculation formula of RBS beam is presented. Moreover law of the RBS beam critical moment varying with cut sizes and location is discussed when compared to the critical moment of the uniform beam. The results show that: reduction has great effect on flexural-torsional buckling of RBS beam, critical moment of the RBS beam obviously decreases as compared with ordinary uniform beam, but single cut parameter has small effect on changes in critical moment; the effect of reduction on beam stiffness decreases as beam span increases.

Objective: The aim of the study was to develop a precise, accurate, and rapid ultraviolet spectrophotometric method for simultaneous estimation of levosulpiride (LEVO) and rabeprazole sodium (RBS) in the binary mixture and to validate the method as per ICH guidelines.Method: Estimation of LEVO and RBS was performed by Q-absorbance method. Analysis was performed using the ratio of absorbance at two selected wavelengths, one at iso-absorptive point and other is the absorbance maxima of any one of the components. Single scan spectrum and the overlain spectrum conclude that absorbance maxima of LEVO and RBS are 228 and 291.8 nm, respectively, with a coinciding iso-absorptive point at 255 nm. Method uses a ratio of absorbance for assay at 255 and the second wavelength is 291.8 nm, λmax for RBS. It is also applicable at 228 nm, as the second wavelength.Results: Linearity of LEVO and RBS was found to be 25-125 and 4-36 μg/ml, respectively. The accuracy of the LEVO and RBS was found 99.26% and 99.51%, respectively and Sandell’s sensitivity ranged between 0.0238 and 0.594 μg/cm2. Assay of LEVO (75 mg) and RBS (20 mg) in capsule dosage form was found 99.5% and 98.69% w/w, respectively.Conclusions: The developed method for the estimation of LEVO and RBS in binary mixture were found to be simple, accurate, robust, and reproducible. No interference of excipients and the degraded product was found during the estimation. Therefore, the method can be successfully applied for routine quality control analysis.RBS) in the binary mixture and to validate the method as per ICH guidelines.Method: Estimation of LEVO and RBS was performed by Q-absorbance method.

Full textAbstract:
Background Combination therapy of α-receptor blockers (α-RBs) and traditional Chinese medicine external therapy can serve as a treatment of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). α-RBs includes tamsulosin, terazosin and so on and the traditional Chinese medicine external therapy includes needling, moxibustion, acupoint catgut embedding, acupoint application, auricular point sticking and hot medicated compress and so forth. Currently, there is no study in which Bayesian network meta-analysis is applied to making a comparative analysis of efficacy of different combination therapies of α-RBs and traditional Chinese medicine external therapy in the treatment of CP/CPPS. Therefore, based on Bayesian algorithm, a network meta-analysis was conducted by us to make a comparison between different combination therapies of α-RBs and traditional Chinese medicine external therapy. Methods A document retrieval was conducted in the databases PubMed, Cochrane Library, Embase, Web of science, China National Knowledge Infrastructure, WanFang Data Dissertations of China database, VIP China Science and Technology Journal Database, SinoMed. Literatures were searched for published in biomedical journals concerning clinical study on α-RBs combined with various traditional Chinese medicine external therapies in the treatment of CP/CPPS from inception of database to July 2022. Newest version risks of bias assessment tool (RoB2) was used to assess the risks of bias of studies included in this analysis. Stata 16.0 software and R4.1.3 software were used to make a Bayesian network meta-analysis and charts. Results 19 literatures were included involving 1739 patients concerning 12 interventions which were used in the treatment of CP/CPPS. With respect to the total effective rate, α-RBs+ needling was most likely to be the optimal treatment. Concerning National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score, α-RBs+ moxibustion+ auricular point sticking was most likely to be optimal treatment, the therapy ranking second was α-RBs+ needling, and the therapy ranking third was α-RBs+ moxibustion. Pain score, voiding score and quality-of-life score are subdomains of the NIH-CPSI total score. With regard to pain score, α-RBs+ moxibustion was most likely to be optimal treatment. In reference to voiding and quality-of-life score, there was no statistically significant difference between the efficacy of various interventions. Conclusions α-RBs+ needling, α-RBs+ moxibustion and α-RBs+ moxibustion+ auricular point sticking provided relatively good efficacy in the treatment of CP/CPPS. In these treatments, attention should be paid on α-RBs+ needling and α-RBs+ moxibustion which ranked higher many times in the evaluation of various outcome indicators. However, there still were certain limitations in this study, so large-sample clinical randomized control trials with a rigor design following the evidence-based medicine standards need to be conducted to justify the results of this study.

10019 Background: Increased risk of second malignant neoplasms (SMN) in retinoblastoma survivors (RBS) is well documented, but little is known about their long-term burden of chronic non-visual morbidity. Methods: RBS treated in NYC were asked to complete a comprehensive questionnaire, adapted from the Childhood Cancer Survivor Study (CCSS) surveys; frequencies of chronic conditions, excluding SMN, in 470 RBS and 2,377 CCSS siblings were calculated. A severity score, based on the NCI CTCAE v4 (ranging from grade 1 [mild] to grade 4 [disabling/life-threatening]) was assigned to each condition. Logistic regression was used to estimateodds ratios of chronic condition risk in RBS vs CCSS siblings, adjusted for age, sex, and race/ethnicity, reported as relative risks (RR) and 95% confidence intervals (CIs). Results: RBS and CCSS siblings were mean ages of 43 years (SD 11) and 38 years (SD 9), respectively, at the time of questionnaire completion. 53.6% of RBS had bilateral disease. After excluding SMN, 70.2% of RBS had at least one non-visual chronic condition while 14% had a grade 3-4 condition. The adjusted RR of a non-visual chronic condition in a survivor compared to siblings was 1.5 (95% CI, 1.2-1.8); for a grade 3-4 condition, the risk was 1.5 (95% CI, 1.1-2.1). The most common grade 3-4 non-visual conditions in RBS were hearing loss (3.6%; bilateral 5.6%, unilateral 1.3%, p=0.023) and thyroid nodules requiring partial or full thyroidectomy (3.4%; bilateral 5.6%, unilateral 0.9%, p=0.008). Rates of grade 3-4 thyroid nodules and hearing loss did not differ significantly when stratified by treatment received. Rates of all conditions in RBS are reported in the Table. Conclusions: RBS have a modestly increased risk of non-visual chronic conditions when compared to individuals of comparable age, sex and race/ethnicity. [Table: see text]

Full textAbstract:
ABSTRACT The Moloney murine leukemia virus (MLV) repressor binding site (RBS) is a major determinant of restricted expression of MLV in undifferentiated mouse embryonic stem (ES) cells and mouse embryonal carcinoma (EC) lines. We show here that the RBS repressed expression when placed outside of its normal MLV genome context in a self-inactivating (SIN) lentiviral vector. In the lentiviral vector genome context, the RBS repressed expression of a modified MLV long terminal repeat (MNDU3) promoter, a simian virus 40 promoter, and three cellular promoters: ubiquitin C, mPGK, and hEF-1a. In addition to repressing expression in undifferentiated ES and EC cell lines, we show that the RBS substantially repressed expression in primary mouse embryonic fibroblasts, primary mouse bone marrow stromal cells, whole mouse bone marrow and its differentiated progeny after bone marrow transplant, and several mouse hematopoietic cell lines. Using an electrophoretic mobility shift assay, we show that binding factor A, the trans-acting factor proposed to convey repression by its interaction with the RBS, is present in the nuclear extracts of all mouse cells we analyzed where expression was repressed by the RBS. In addition, we show that the RBS partially repressed expression in the human hematopoietic cell line DU.528 and primary human CD34+ CD38− hematopoietic cells isolated from umbilical cord blood. These findings suggest that retroviral vectors carrying the RBS are subjected to high rates of repression in murine and human cells and that MLV vectors with primer binding site substitutions that remove the RBS may yield more-effective gene expression.

Full textAbstract:
Introduction. Rice bodies (RBs) are pale and glossy appearing small fibrinous nodules that form due to synovial or tenosynovial joint inflammation. RBs are significant as they are common in orthopedic practices causing nonspecific symptoms such as pain, swelling, range of motion limitations, crepitus, and catching sensations. These loose bodies occur often within the bursa as a symptom of chronic bursitis and are commonly associated with rheumatoid, inflammatory, or tuberculous arthritis. Reports on RBs are present; however, few bilateral cases within the shoulder appear in the literature. Case Presentation. This case demonstrates an unusual bilateral, subacromial-subdeltoid presentation of rice bodies (RBs) in a 41-year-old Caucasian female patient with a history of rheumatoid arthritis. We describe treatment with right shoulder arthroscopy to remove the loose bodies. One-year postoperative patient-reported outcomes (PROMs) show improvement in symptoms, pain, and overall function. Conclusion. Formation of RBs occurs as a symptom of an inflammatory response in synovial joints. This provokes multiple small fibrin aggregates to collect within synovial bursae and occasionally tendon sheaths. RBs are rarely seen bilaterally. Arthroscopic removal of RBs is an appropriate treatment method for symptom improvement.

In today’s world, braking is the most important system in an Automobile. Brakes are energy conversion devices, which convert kinetic energy of the vehicle into thermal energy. Most brakes commonly use friction between two surfaces to convert the kinetic energy of the moving object into heat. RBS converts much of the energy to electrical energy, which may be stored for later use. Thus in Regenerative Braking the efficiency is improved as it result in an increase in an energy output for a given energy input to a vehicle. The amount of work done by the engine of the vehicle is reduced, in turn reducing the amount of energy required to drive the vehicle. Since we do not have any reliable alternative source of energy, increasing efficiency and reducing exhaust gas emissions has become the focus which can be bit achieved by RBS.

Objective: This study compared the effectiveness of 4 main revisional bariatric surgery (RBS) sequences after sleeve gastrectomy (SG) and adjustable gastric banding (AGB), on the reimbursement of antidiabetic treatments in France. Background: Few large-scale prospective cohort studies have assessed the changes in antidiabetic treatments after RBS. Method: This nationwide observational population-based cohort study analyzed data from the French National Health Insurance Database. All patients who underwent primary SG and AGB in France between January 2012 and December 2014 were included and followed up until December 31, 2020. The changes in categories and costs of reimbursed antidiabetic treatments across different RBS sequences were assessed (presented as follows: bariatric surgery (BS)-RBS). Results: Among the 107,088 patients who underwent BS, 6396 underwent RBS, 2400 SG-GBP (SG converted to gastric bypass [GBP] during follow-up), 2277 AGB-SG, 1173 AGB-GBP, and 546 SG-SG. Pre-RBS insulin was used in 10 (2.9%), 4 (0.9%), 8 (2.4%), and 10 (2.6%) patients, respectively. Two years after RBS, the treatment discontinuation or decrease (the change of treatment to a lighter one category rates [eg, insulin to bi/tritherapy]) was 47%, 47%, 49%, and 34%, respectively. Four years after RBS, the median annual cost per patient compared with baseline was lower (P < 0.01) for all sequences, except SG-SG (P = 0.24). The most notable effect concerned AGB-GBP (median of more than 220 euros to 0). Conclusions: This study demonstrated the positive impact of RBS over a 4-year follow-up period on antidiabetic treatments reimbursement, through the reduction or discontinuation of treatments and a significant decrease in costs per patient.

The U.S. Department of Agriculture Rural Business-Cooperative Service (RBS) was established with the goal of fostering rural development through grants and low-interest loans. However, rural revitalization is only effective if funds reach their intended recipients. With congressional oversight of the U.S. Department of Agriculture and geographic concentration of RBS benefits, the RBS may deviate from its stated objectives to satisfy congressional preferences. Using RBS grant and loan data from 2006 to 2014, the author performs a test of the congressional dominance model. The empirical results show that congressional membership on the relevant House and Senate subcommittees is associated with greater RBS funding. Congressional influence is a plausible mechanism through which development funding fails to reach those in the areas of greatest need.

Since pits and fissures are the areas most commonly affected by caries due to their structural irregularity, bioactive resin-based sealant (RBS) may contribute to the prevention of secondary caries. This study aims to investigate the mechanical, physical, ion-release, enamel remineralisation, and antibacterial capabilities of the novel RBS with bioactive glass (BAG) and 2-methacryloyloxyethyl phosphorylcholine (MPC). For the synthesis, 12.5 wt% BAG and 3 wt% MPC were incorporated into RBS. The contact angle, flexural strength, water sorption, solubility, and viscosity were investigated. The release of multiple ions relating to enamel remineralisation was investigated. Further, the attachments of bovine serum albumin, brain heart infusion broth, and Streptococcus mutans on RBS were studied. Finally, the thickness and biomass of a human saliva-derived microsm biofilm model were analysed before aging, with static immersion aging and with thermocycling aging. In comparison to commercial RBS, BAG+MPC increased the wettability, water sorption, solubility, viscosity, and release of multiple ions, while the flexural strength did not significantly differ. Furthermore, RBS with MPC and BAG+MPC significantly reduced protein and bacteria adhesion and suppressed multi-species biofilm attachment regardless of the existence of aging and its type. The novel RBS has great potential to facilitate enamel remineralisation and suppress biofilm adhesion, which could prevent secondary dental caries.

Background Improved interventions are needed to reduce the rate of driving while intoxicated. Responsible beverage service (RBS) training has reduced service to intoxicated patrons in licensed premises in several studies. Its efficacy might be improved by increasing the proper application and continued use of RBS with a professional development program in the 3 to 5 years between the required RBS retraining. Objective This study aims to develop and evaluate a professional development component for an RBS training that aims to improve the effectiveness of the web-based training alone. Methods In a 2-phase project, we are creating a professional development component for alcohol servers after completing an RBS training. The first phase involved formative research on the feasibility, acceptability, and potential effectiveness of components. Semistructured interviews with owners and managers of licensed establishments and focus groups and a survey with alcohol servers in New Mexico and Washington State examined support for RBS and the need for ongoing professional development to support RBS. A prototype of a professional development component, WayToServe Plus, was produced for delivery in social media posts on advanced RBS skills, support from experienced servers, professionalism, and basic management training. The prototype was evaluated in a usability survey and a field pilot study with alcohol servers in California, New Mexico, and Washington State. The second phase of the project will include full production of the professional development component. It will be delivered in Facebook private groups over 12 months and evaluated with a sample of licensed premises (ie, bars and restaurants) in California, New Mexico, and Washington State (n=180) in a 2-group randomized field trial (WayToServe training only vs WayToServe training and WayToServe Plus). Licensed establishments will be assessed for refusal of sales to apparently intoxicated pseudopatrons at baseline and 12 months after the intervention commences. Results Although owners and managers (n=10) and alcohol servers (n=43) were favorable toward RBS, they endorsed the need for ongoing support for RBS for servers and identified topics of interest. A prototype with 50 posts was successfully created. Servers felt that it was highly usable and appropriate for themselves and the premises in the usability survey (n=20) and field pilot test (n=110), with 85% (17/20) and 78% (46/59), respectively, saying they would use it. Servers receiving the professional development component had higher self-efficacy (d=0.30) and response efficacy (d=0.38) for RBS compared with untreated controls. Conclusions Owners, managers, and servers believed that an ongoing professional development component on RBS would benefit servers and licensed premises. Servers were interested in using such a program, a large majority engaged with the prototype, and servers receiving it improved on theoretic mediators of RBS. Thus, the professional development component may improve RBS training.

Roberts syndrome (RBS) is a rare developmental disorder that can include craniofacial abnormalities, limb malformations, missing digits, intellectual disabilities, stillbirth, and early mortality. The genetic basis for RBS is linked to autosomal recessive loss-of-function mutation of the establishment of cohesion (ESCO) 2 acetyltransferase. ESCO2 is an essential gene that targets the DNA-binding cohesin complex. ESCO2 acetylates alternate subunits of cohesin to orchestrate vital cellular processes that include sister chromatid cohesion, chromosome condensation, transcription, and DNA repair. Although significant advances were made over the last 20 years in our understanding of ESCO2 and cohesin biology, the molecular etiology of RBS remains ambiguous. In this review, we highlight current models of RBS and reflect on data that suggests a novel role for macromolecular damage in the molecular etiology of RBS.

Abstract Reed bed systems (RBS) have potential to treat wastewater, and being interested in such green wastewater infrastructures, an RBS has been installed for the first time in Bangladesh to treat faecal wastewater, which comes from a low-cost community latrine at a refugee camp in Cox's Bazar area. An anaerobic baffle reactor was set followed by the RBS, which was operated continuously for four months at five different retention times (3–7 days). The RBS was found to retain, on average, about 92% of 5-day biochemical oxygen demand (BOD5) and chemical oxygen demand (COD), 69% of and 52% of . Importantly, the effluent concentration met the national environmental standard for all except for . Thus the optimum hydraulic retention time in RBS has been selected to be 3 days when the ion has been reduced at maximum rate. High positive correlation () was observed between and concentrations in effluent water as well. The results of this study, thus, partly support the RBS as an effective green solution for faecal wastewater treatment.

Full textAbstract:
A rubber isolation bearing installed in a staircase (RBS) was proposed to mitigate seismic damages to the component of staircases and improve their seismic performance. A series of quasi-static tests performed with respect to the horizontal and vertical mechanical properties of RBS as well as the numerical modelling were verified with experimental results. Next, the finite element models of typical types of reinforced concrete frames (without stairs, with cast-in-place reinforced concrete stairs, and with RBS stairs) were established. The modal dynamic and non-linear elasto-plastic analyses of system-level building models were herein conducted, respectively. The effect of the RBS on the dynamic response of the whole structure and the mechanical performance of stair components was revealed. The analysis results indicated that the RBS provided the desired floor-to-floor relative drift and effectively isolate the seismic action from the stair flight. Therefore, the presence of RBS can effectively mitigate the influence of a staircase on the entire building’s structure, weaken the diagonal strut effect of flights, and reduce the inner forces of staircase components.

Engineers prefer reduced beam section (RBS) connections in steel moment frames built in earthquake zones due to their many benefits. The RBS shape design significantly affects joint behavior. This paper examines the effect of RBS geometry on joint behavior and seismic performance using ANSYS finite element analysis software. RBS connections are investigated using European profiles and steel grades due to the limited number of studies using European profiles in the literature. The simulation study is carried out in three stages. In the first stage, an experimental study in the literature is simulated, and the reliability of the created finite element model is checked. In the second stage, geometric changes are made to the verified numerical model, and the obtained new models are examined under monotonic loading to observe the effect of RBS geometry on moment-rotation behavior. In the third stage, the effect of the change in the RBS geometry on the seismic performance is investigated under cyclic loading. As a result of the study, the effects of various changes made in the RBS geometry on the joint behavior and seismic performance are presented graphically. By using the results of the analysis under monotonic loading, the regression analysis is carried out, and the formulas giving the elastic-plastic stiffness, elastic moment capacity, and elastic rotation angle of the support are derived. Besides, simulation models show that the RBS joints' seismic performance met the minimum criteria specified in the earthquake code (AISC/ANSI 341-16) when European steel profiles and quality are applied.

This research evaluates the energy gain from a regenerative braking system (RBS) in a commercial electric vehicle (EV), the OEM Mitsubishi i-MiEV. Measurements were conducted in a controlled environment on a commercial chassis dynamometer using international drive cycle standards. The energy recovery of the vehicle was modelled and the output of the model was compared with results from the chassis dynamometer driving. The experiments were original as they coupled changes in energy recovered and driving range due to the RBS settings with investigations into the time of use of the friction brake. Performance tests used two different drive cycle speed profiles and various RBS settings to compare energy recovery performance for a broad range of driving styles. The results show that due to reduced energy consumption, the RBS increased the driving range by 11–22% depending on RBS settings and the drive cycle settings on the dynamometer. The results further showed that driving an EV with a RBS uses the friction brakes more efficiently, which will reduce brake pad wear. This has the potential to improve air quality due to reduced brake pad dust and reduces the maintenance costs of the vehicle. The findings were significant since they showed that friction time of use, a parameter neglected in RBS testing, plays an important part in the efficient operation of an EV. The overall results from the vehicle energy recovery modelling showed good agreement with the data from drive cycle testing and the model has potential to be further developed to gain greater insight into vehicle RBS braking behaviour for EVs in general.

Abstract The effect of 1 MeV Au+ ion irradiations on the layer stability of the Fe3O4-based films grown epitaxially on MgO(001) substrates was investigated by Rutherford backscattering spectroscopy (RBS) and RBS-Channelling (RBS-C). The ion mixing effect leads to an appearance of the additional FeO x layer and a large enlargement of the thickness of the mixed (Fe,Mg,O) layer in the interfaces. Au+ ions were found to be implanted deeply in the MgO substrate. RBS-C experiments have confirmed that the heavy metallic ion irradiations induce a disorder in the crystalline lattice.

Full textAbstract:
The subject of this study is systems for detection and identification (D&I) of explosive ordnance (EO). The aim of this study is to develop a concept, general structure, and models of a robotic-biological system for D&I of EO (RBS-D&I). The objectives are as follows: 1) to classify mobile systems for D&I of EO and suggest a concept of RBS-D&I; 2) to develop the general structure of RBS-D&I consisting of robotic (flying and ground) and biological subsystems; 3) to develop models of RBS-D&I including automaton, hierarchical, and operational ones; 4) to describe tasks and planned results of the article-related scientific project; and 5) to discuss research results. The following results were obtained. 1) The general structure of the RBS-D&I. The structure comprises the following levels: control and processing centres (mobile ground control and processing centre (MGCPC) and virtual control and processing centre); forces for detection and identification (fleet of unmanned aerial vehicles (FoU), biological detection information subsystem (BDIS), and robotic detection information subsystem (RDIS)); interference; natural covers and a bedding surface; and target objects (all munitions containing explosives, nuclear fission or fusion materials and biological and chemical agents). 2) A concept of RBS-D&I. The concept is based on RBS-D&I description, analysis, development, and operation as an integrated complex cyber-physical and cyber-biological system running in changing physical and information environments. 3) The RBS-D&I automata model. The model describes RBS-D&I operating in two modes. In mode 1, FoU and BDIS operate separately and interact through the MGCPC only. In mode 2, depending on the specifics of the tasks performed, FoU and RDIS can directly interact among themselves or through the MGCPC. 4) hierarchical model. The model has two sets of vertices: EO detection and platforms equipped with the necessary sensors. 5) An operational cycle model. The model describes land release operations via a methodology of functional modeling and graphic description of IDEF0 processes. Conclusions. The proposed concept and RBS-D&I solutions can provide high-performance and guaranteed EO detection in designated areas by the implementation of an intelligent platform and tools for planning the use of multifunctional fleets of UAVs and other RBS-D&I subsystems.

Abstract Eight ruminally cannulated beef steers were used to evaluate forage intake and physiological response during adaptation to a diet consisting of bermudagrass round bale silage (RBS) and dried distillers grains (DDG) and in a second experiment the effect of level of DDG supplementation on RBS forage intake, digestibility, and rumen parameters. The adaptation experiment was designed to simulate a 14-d step-up process. Initially steers received ad libitum RBS, on d 4 steers were offered 1.13 kg of DDG daily and every 4 d daily DDG offered was increased by 1.13 kg. Blood and rumen fluid samples were collected before feeding (0 h) and 6, 12, 24 (before feeding), and 36 h after every diet change. The digestibility experiment was conducted as an 8 × 4 Latin square with four periods. Treatments included RBS only and DDG supplement levels of 0.33%, 0.66%, and 1.0% of body weight (RBS + 0.33, +0.66, and 1.0, respectively). Collection periods consisted of 21 d to determine dry matter intake [DMI], digestibility, and collect rumen fluid samples. During adaptation, level of DDG did not (P = 0.42) affect RBS DMI. Mean ruminal pH was greater (P < 0.05) for RBS only compared with diets with DDG. When steers were offered 3.39 or 4.52 kg/d of DDG rumen NH3-N concentration was greater (P ≤ 0.05) compared with other levels of DDG or RBS alone. Mean nonesterified fatty acid and plasma urea N concentrations varied among levels of DDG offered. In the digestibility experiment forage DMI, total DMI, and total tract apparent digestibility exhibited a quadratic (P ≤ 0.05) response to level of DDG offered. Mean ruminal pH responded in a quadratic manner (P = 0.03) and was greater for RBS only compared with RBS plus DDG at any level. Mean ruminal NH3-N concentration tended (P = 0.07) to respond in a cubic manner as DDG amount offered increased. Physiological responses during adaptation to DDG over 14 d resembled responses previously observed after long-term DDG supplementation. Offering DDG up to 1% of body weight did depress forage DMI and ruminal pH but increased total DMI, diet digestibility, and ruminal NH3-N concentration.

Full textAbstract:
This research presents an approach to the hybrid energy harvesting paradigm (HEHP) based on suspended energy harvest. It uses a harvesting vibration absorber (HVA) with an SC/NMC-lithium battery hybrid energy storage paradigm (SCB-HESP) equipped regenerative braking system (SCB-HESP-RBS) for electric vehicles 2 tons in gross weight (MEVs) driven by a 30 kW permanent magnet synchronous motor (PMSM). During regenerative braking, the ANN mechanism controls the RBS to adjust the switching waveform of the three-phase power inverter, and the braking energy transfers to the energy storage device. Additionally, a supercapacitor (SC) equipped with HVA can absorb energy from vehicle vibrations and convert it into electrical energy. The energy-harvesting efficiency of MEV based on SCB-HESP-RBS using HVA suspended energy harvesting enhances the efficiency maximum to 50.58% and 15.36% in comparison to MEV with only-HVA and SCB-HESP-RBS, respectively. Further, the MEV with SCB-HESP-RBS using HVA has a driving distance of up to 247.34 km (22.5 cycles) when compared with SCB-HESP-RBS (214.40 km, 19.5 cycles) and only-HVA (164.25 km, 15 cycles).

Background: In recent years, several studies have correlated pitch count with an increased risk for injury among baseball pitchers. However, no studies have attempted to draw a similar conclusion based on number of carries by running backs (RBs) in football. Purpose: To determine whether there is a correlation between number of carries by RBs in the National Football League (NFL) and risk of injury or worsened performance in the subsequent season. Study Design: Cohort study; Level of evidence, 3. Methods: The ESPN NFL statistics archives were searched from the 2004 through 2014 regular seasons. During each season, data were collected on RBs with 150 to 250 carries (group A) and 300+ carries (group B). The following data were collected for each player and compared between groups: number of carries and mean yards per carry during the regular season of interest and the subsequent season, number of games missed due to injury during the season of interest and the subsequent season, and the specific injuries resulting in missed playing time during the subsequent season. Matched-pair t tests were used to compare changes within each group from one season to the next in terms of number of carries, mean yards per carry, and games missed due to injury. Results: During the seasons studied, a total of 275 RBs were included (group A, 212; group B, 63). In group A, 140 RBs (66%) missed at least 1 game the subsequent season due to injury, compared with 31 RBs (49%) in group B ( P = .016). In fact, players in group B missed significantly fewer games due to injury during the season of interest ( P < .0001) as well as the subsequent season ( P < .01). Mean yards per carry was not significantly different between groups in the preceding season ( P = .073) or the subsequent season ( P = .24). Conclusion: NFL RBs with a high number of carries are not placed at greater risk of injury or worsened performance during the subsequent season. These RBs may be generally less injury prone compared with other NFL RBs.

One newer moment connection that has been introduced and validated (prequalified) for use in high seismic areas is the so-called "dogbone"ť, or reduced beam section (RBS). The purpose of this paper is to briefly review the basic in-plane stiffness formulation for a prismatic beam, develop more rigorously the full non-prismatic, first-order elastic stiffness changes caused by the circular RBS, provide its simplified representation, and finally conclude with the general RBS stiffness effect suggestions for design. Other RBS seismic design and performance issues of this efficient and popular detail will not be addressed, as they are already well covered in other available sources.

Objective This study aimed to monitor the secretion of serotonin and melatonin in the blood serum of rats in the presence of rice bran (RB), and Sarcodon aspratus (S) extracts for sleep promotion. Background Sleep is a natural physiological phenomenon, and sleep disorders may cause severe mental hazards leading to excessive daytime sleepiness (EDS). The γ-aminobutyric acid (GABA) and β-glucan are the essential active ingredients of RB and mushroom, respectively, exhibited stress-reduction and nerve stabilizing potential through regulation of melatonin and serotonin hormones. Methods Cytotoxicity of the extracts (RBS) was evaluated through WST-1 assay. The melatonin and serotonin concentrations in the blood serum were measured through ELISA kits. The Ig ELISA kit measured the immunoglobulin’s (IgG, IgM, and IgA) concentrations. Results Improved cell viability was observed in RBS treated groups than control, indicating their biocompatibility. The melatonin and serotonin levels were high in RBS (5:5 and 7:3) treated groups compared to the control. Enhanced expression of immunoglobulin (Ig) A and G level was observed in RBS treated rats. The serotonergic genes (5-HTT, 5-HT 1B, and MAO-A) expression levels were upregulated in RBS treated groups vis-à-vis the control. Conclusion Based on these results, we anticipated that RBS supplements could promote the sleep phenomenon by elevating the serotonin/melatonin level in the blood through the serotonergic system. Therefore, RBS supplements can be utilized as functional food material for sleep promotion.
