Résumé :

Abstract Factor J (FJ) is a cationic glycoprotein that is able to inhibit in vitro both the classical and alternative pathways of complement. FJ was purified to homogeneity from human urine by sequential chromatographic steps. To examine the expression of FJ in human cells we obtained mAbs against urine-purified FJ. Preliminary studies by immunocytochemistry revealed that one of the anti-FJ mAbs recognized cell surface components of certain cell lines, such as K562 and U937 cells, so we have focused subsequently on the detection of these homologue membrane-bound FJ Ags (FJ-h Ags) in cell lines of lymphoid (Ramos and Jurkat) and mieloyd (U937 and K562) origin, as well as in peripheral blood cells. The flow cytometry analysis of the examined cell lines revealed partial staining ranging from 10% (U937) to 29% (K562) positive cells. Flow cytometry of peripheral blood cells showed a positive staining in a small but consistent population of lymphocytes (mean = 11%, n = 17) but none at all on monocytes, granulocytes, erythrocytes, or platelets. Double Ab immunostaining of lymphocytes showed that the FJ-h positive population included mainly B lymphocytes (a mean of 63% CD19+ were FJ-h positive). When we analyzed peripheral blood lymphocytes from a patient with chronic lymphocytic leukemia B (95% CD19+/CD5+), the majority of these (55%) bore FJ-h on their surface. Acid strip of these cells did not abrogate the surface staining, which supports the finding that the Ag is tightly bound to the membrane. Immunoprecipitation from U937 cell lysates showed a single 65 kDa band under reducing conditions. FJ-h Ags purified from K562 and U937 cells displayed inhibitory activity in the functional EAC14 assay for the classical complement pathway, as did urine FJ, and they were recognized immunochemically by five different (one polyclonal and four monoclonal) anti-FJ Abs. In conclusion, FJ-homologues are present in the membranes of several human cell lines that show functional and antigenic characteristics similar to soluble urine FJ. They are also found in a small subset of peripheral blood lymphocytes, mainly B cells. The structural relationship between both soluble urine FJ and these membrane-bound FJ-h remains to be established.

Résumé :

The purpose of this study was to investigate hospital variation in the placement, surgical techniques, and safety of feeding jejunostomies (FJ) during minimally invasive esophagectomy (MIE) in the Netherlands. This nationwide cohort study analyzed patients registered in the Dutch Upper Gastrointestinal Cancer Audit (DUCA) that underwent MIE for cancer. Hospital variation in FJ placement rates were investigated using case-mix corrected funnel plots. Short-term outcomes were compared between patients with and without FJ using multilevel multivariable logistic regression analysis. The incidence of FJ-related complications was described and compared between hospitals performing routine and non-routine placement (≥90%–<90% of patients). Between 2018–2020, an FJ was placed in 1481/1811 (81.8%) patients. Rates ranged from 11–100% among hospitals. More patients were discharged within 10 days (median hospital stay) without FJ compared to patients with FJ (64.5% vs. 50.4%; OR: 0.62, 95% CI: 0.42–0.90). FJ-related complications occurred in 45 (3%) patients, of whom 23 (1.6%) experienced severe complications (≥Clavien–Dindo IIIa). The FJ-related complication rate was 13.7% in hospitals not routinely placing FJs vs. 1.7% in hospitals performing routine FJ placement (p < 0.001). Significant hospital variation in the use of FJs after MIE exists in the Netherlands. No effect of FJs on complications was observed. FJs can be placed safely, with lower FJ-related complication rates, in centers performing routine placement.

Résumé :

Background: Concomitant placement of Feeding Jejunostomy (FJ) tubes is common after pancreaticoduodenectomy for optimizing postoperative nutrition. The aim of this study is to determine the role FJ tube placement for postoperative nutrition following pancreaticoduodenectomy.Methods: All patients undergoing concomitant FJ following pancreaticoduodenectomy (Whipples procedure) from July 2014 to July 2016 were reviewed retrospectively. FJ feeds were routinely started on POD 2. Jejunostomy feeds were discontinued once patient is able to take adequate oral feeds. Data were represented by frequency and mean.Results: A total of 28 patients underwent pancreaticoduodenectomy in the study period and concomitant FJ was performed in all those patients. A total of 18 (64.3%) were men and mean age was 47.1 years. Majority (25, 89.3%) of these patients had malignancy as an indication for surgery. Only 6 out of 28 (21.4%) patients required nutrition supplementation through FJ on POD 7. Only 2 out of 28 (7.1%) patients required FJ feeds on POD 30. None of these patients had tube related complications in 30-day postoperative period. There was no FJ related mortality in 30-day postoperative period. The patients who required prolonged FJ feeds had grade C pancreatic leak, gastrojejunal anastamotic leak and GJ anastamotic stricture.Conclusions: Concomitant FJ can be used as a routine in patients undergoing pancreaticoduodenectomy. It is especially beneficial among patients requiring prolonged postoperative nutritional supplementation due to grade c pancreatic leak and gastrojejunal anastamotic leak. Literature review suggested that one third of the nasojejunostomy tubes dislodge and TPN doubles the risk of infection, hence FJ is considered safe and effective adjunct for patients undergoing pancreaticoduodenectomy.

Résumé :

Dietary guidelines often deal with 100% fruit juice (FJ) inconsistently because it represents a source of free sugars. However, FJ also provides bioavailable micronutrients and plant bioactives at levels similar to those found in whole fruits. The present review weighs up the evidence from high-quality studies investigating a potential health harm for FJ against evidence from studies which indicate a potential health benefit. The findings reveal that FJ consumption, at moderate intakes consistent with the dietary guidelines for the US and some European countries (75–224 mL daily), does not increase the risk of obesity, type 2 diabetes, cardiovascular disease or poor glycaemic control. In contrast, regular consumption of FJ—even up to 500 mL per day in short-to-medium-term studies—appears to confer a health benefit in terms of vascular function and reduced blood pressure. Emerging evidence for cognitive health benefits requires further investigation in human trials. Observational studies report associations between FJ and nutrient adequacy and suggest that FJ consumption is associated with reduced risk of stroke. In conclusion, FJ appears to offer more benefit than risk and there appears to be no justification for discouraging FJ within a balanced diet for children and adults.

Résumé :

ABSTRACT In 2001 and 2003, we isolated two H5N1 viruses, A/swine/Fujian/1/01 (SW/FJ/01) and A/swine/Fujian/1/03 (SW/FJ/03), from pigs in Fujian Province, southern China. Genetically, these two viruses are similar, although the NS gene of the SW/FJ/03 virus has a 15-nucleotide deletion at coding positions 612 to 626. The SW/FJ/01 virus is highly lethal for chickens, whereas the SW/FJ/03 virus is nonpathogenic for chickens when administrated intravenously or intranasally. To understand the molecular basis for the difference in virulence, we used reverse genetics to create a series of single-gene recombinants of both viruses. We found that a recombinant virus containing the mutated NS gene from the SW/FJ/03 virus in the SW/FJ/01 virus background was completely attenuated in chickens. We also found that viruses expressing the mutant NS1 protein of SW/FJ/03 did not antagonize the induction of interferon (IFN) protein. Conversely, only the recombinant virus containing the wild-type SW/FJ/01 NS gene in the SW/FJ/03 background was lethal in chickens and antagonized IFN protein levels. Further, we proved that the NS1 genes of the two viruses differ in their stabilities in the host cells and in their abilities to interact with the chicken cleavage and polyadenylation specificity factor. These results indicate that the deletion of amino acids 191 to 195 of the NS1 protein is critical for the attenuation of the SW/FJ/03 virus in chickens and that this deletion affects the ability of the virus to antagonize IFN induction in host cells.

Résumé :

We retrospectively analyzed CT scans of 620 individuals, who presented to our traumatology department between 2008 and 2010. Facet joint (FJ) arthritis was present in 308 (49.7%) individuals with a mean grade of 1. It was seen in 27% of individuals ≤40 years and in 75% of individuals ≥41 years () as well as in 52% of females and 49% of males (). Mean FJ orientation was 30.4° at L2/3, 38.7° at L3/4, 47° at L4/5, and 47.3° at L5/S1. FJ arthritis was significantly associated with more coronal (increased degree) FJ orientation at L2/3 () with a cutoff point at ≥32°. FJs were more coronally oriented (48.8°) in individuals ≤40 years and more sagittally oriented (45.6°) in individuals ≥41 years at L5/S1 (). Mean FJ asymmetry was 4.89° at L2/3, 6.01° at L3/4, 6.67° at L4/5, and 7.27° at L5/S1, without a significant difference for FJ arthritis. FJ arthritis is common, increases with age, and affects both genders equally. More coronally oriented FJs (≥32°) in the upper lumbar spine may be an individual risk factor for development of FJ arthritis.

Résumé :

ObjectivesThe size and shape of a joint cavity are the key determinates for the mobility of the joint. The anatomy and configuration of the facet joint (FJ) recesses at different levels of the spine remain unclear and controversial. The aim of this study was to identify the configuration of the FJ recesses in the cervical, thoracic and lumbar spine using a combination of micro-CT and sheet plastination techniques.MethodsOf 19 cadavers (9 males, 10 females, age range of 54–89 years), the FJ cavities of 3 spines were injected with contrast filling and scanned with micro-CT, and 16 plastinated spines were prepared as the series of sagittal (9 sets), transverse (5 sets) or coronal (2 sets) sections with a thickness of 2.5 mm and examined under a stereoscopic microscope.ResultsThis study characterised the FJ spaces and recesses of the spine and found that (1) the configuration and extent of the FJ recesses varied along the spine. The optimal needle approach to the FJ cavity was via an anterolateral or posterolateral recess at the cervical level, along the tip of the inferior articular process at the thoracic level and via the posteromedial recess at the lumbar level. (2) The FJ cavity did not communicate with the retrodural space.ConclusionThe anatomical features of the FJ recesses at different levels of the spine confirm no direct communication between the FJ cavity and retrodural space.

Résumé :

Abstract The widely used model for evolutionary relationships is a bifurcating tree with all taxa/observations placed at the leaves. This is not appropriate if the taxa have been densely sampled across evolutionary time and may be in a direct ancestral relationship, or if there is not enough information to fully resolve all the branching points in the evolutionary tree. In this article, we present a fast distance-based agglomeration method called family-joining (FJ) for constructing so-called generally labeled trees in which taxa may be placed at internal vertices and the tree may contain polytomies. FJ constructs such trees on the basis of pairwise distances and a distance threshold. We tested three methods for threshold selection, FJ-AIC, FJ-BIC, and FJ-CV, which minimize Akaike information criterion, Bayesian information criterion, and cross-validation error, respectively. When compared with related methods on simulated data, FJ-BIC was among the best at reconstructing the correct tree across a wide range of simulation scenarios. FJ-BIC was applied to HIV sequences sampled from individuals involved in a known transmission chain. The FJ-BIC tree was found to be compatible with almost all transmission events. On average, internal branches in the FJ-BIC tree have higher bootstrap support than branches in the leaf-labeled bifurcating tree constructed using RAxML. 36% and 25% of the internal branches in the FJ-BIC tree and RAxML tree, respectively, have bootstrap support greater than 70%. To the best of our knowledge the method presented here is the first attempt at modeling evolutionary relationships using generally labeled trees.

Résumé :

Chinese Jujube has long been used for human consumption and medicinal purposes in China. The objective of this study was to extract active substance from the powder of fermented Chinese Jujube and to detect their antioxidant capacities. Macroreticular resin was used to separate FJ-1 from 60% ethanol extract, and silica gel column was used for further separation of FJ-2. Precipitation of CPJ was conducted by addition of 95% ethanol to the water extract. The ability to eliminate DPPH•, O2• and •OH of this component was analyzed. Their activities show dose dependence character. FJ-1, FJ-2 show excellent antioxidant capacity on eliminating DPPH• and •OH, but CPJ shows lower capacity. The capacity on eliminating O2• of CPJ is higher than FJ-1, FJ-2 at the same concentration.

Résumé :

Abstract Background and Aim Carcinoma of the stomach is one of the leading causes of mortality worldwide. Surgery for gastric cancer in the form of total or distal gastrectomy is definitive treatment. Feeding jejunostomy (FJ) though improves postoperative nutritional status and outcome, it is not devoid of its complications. In this study, we present the outcomes of nasojejunal (NJ) feeding and FJ and complications associated with them. Materials and Methods It is both retrospective and prospective observational study in patients with gastric cancer undergoing surgery. Patients were divided into two groups: those who underwent FJ and those who underwent NJ route of feeding placed intraoperatively. Results A total of 279 patients of gastric cancer who underwent surgery were taken into study, of which, 165 were male and 114 females. FJ was done in 42 and NJ in 237 patients, respectively. Gastrectomy + NJ was done in 128 patients, gastrectomy + FJ in 27 patients, gastrojejunostomy + NJ in 109 patients, and FJ in 15 patients. We had three patients of bile leaks in FJ group, of which one patient had intraperitoneal leak who needed re-exploration; rest of the two had peri-FJ external leaks, who were managed conservatively. Most of the complications of NJ group were minor. Conclusion Our study of 279 patients in gastric cancer has shown that FJ is sometimes associated with major complications with increased hospital stay and morbidity when compared with NJ tube feeding without any difference in nutritional outcomes. Hence, NJ route of postoperative enteral nutrition can be considered as an alternative to FJ wherever feasible in view of its technical safety and minor complications and morbidity.

Résumé :

Fluorescein-derived fluorochromes and anionic dyes such as Fluoro-Jade (FJ) stains have been introduced to facilitate recognition of dying neurons in tissue sections. However, the definition of what is really detected by FJ-based stains and its sensitivity in the detection of neuronal cell death is unclear. In our work, we evaluated the outcome of FJ-C staining in mouse brains from 4 different well-characterized models of neurodegeneration. Neuronal degeneration and loss were highlighted with high sensitivity by FJ-C stain in mice with dysfunctional γ-secretase in the glutamatergic neurons and in mice affected by acute cerebral ischemia. Histopathologically, acute eosinophilic necrosis or “red dead” neurons were associated with FJ-C staining in both settings. Conversely, in mice affected by chronic cerebral microinfarcts due to tumor lysis syndrome as well as in a model of mitochondrial encephalopathy, FJ-C staining failed to detect neuronal death. Histopathologically, these models were characterized by extensive neuronal vacuolation associated with fading neurons (“ghost cells”). Therefore, contrary to the widespread belief that FJ-C stain has high affinity for all degenerating neurons regardless of the underlying cell death mechanism, we observed restricted sensitivity of the technique to specific conditions of neuronal cell death. As such, complementary techniques are essential to evaluate the presence of neurodegeneration in the absence of a positive FJ-C signal.

Résumé :

The contribution of 100% fruit juice (FJ) to the total daily intakes of energy, sugars, and select vitamins and minerals and to the recommended dietary allowances (RDAs) or adequate intake (AI) of these micronutrients was assessed in individuals reporting the consumption of 100% FJ in the national dietary intake surveys of the United States (U.S.; n = 8661), the United Kingdom (UK; n = 2546) and Brazil (n = 34,003). Associations of 100% FJ intake with the odds of being overweight or obese also were assessed. Data from the U.S. National Health and Nutrition Examination Survey (2013–2014), the UK National Diet and Nutrition Survey (2012–2014), and Brazil’s Pesquisa de Orçamentos Familiares (2008–2009) were used, and all analyses were limited to individuals reporting consumption of 100% FJ on at least one day of the dietary intake survey. Approximately 34%, 37%, and 42% of individuals surveyed reported the consumption of 100% FJ on at least one day of the dietary intake survey in the U.S., UK, and Brazil, respectively, and the average daily intakes of 100% FJ were 184 g, 130 g, and 249 g, respectively. Across the 3 countries, 100% FJ contributed to 3–6% of total energy intakes, 12–31% of total sugar intakes, 21–54% of total vitamin C intakes, 1–12% of total vitamin A intakes, 4–15% of total folate intakes, 7–17% of total potassium intakes, 2–7% of total calcium intakes, and 4–12% of total magnesium intakes. In a multivariate logistic regression model, juice intake was associated with a significant reduction in the odds of being overweight or obese in UK adults (OR = 0.79; 0.63, 0.99), and significant increases in the odds of being overweight or obese in UK children (OR = 1.16; 1.01, 1.33) and Brazilian adults (OR = 1.04; 1.00, 1.09). Nutrient contributions of 100% FJ vary according to regional intake levels. In all three countries studied, 100% FJ contributed to more than 5% of the RDAs for vitamin C and folate. In the U.S. and Brazil, 100% FJ contributed to more than 5% of the RDA for magnesium and more than 5% of the AI for potassium.

Résumé :

Structural Finger-jointed (FJ) lumber is a common building material used mainly in timber construction. The paper evaluated the factors influencing structural performances of FJ Chinese fir lumber. Lumber was sawn from the logs following a pattern typically used in China to maximize the volume of recovered sawn timbers. After kiln-drying, the rough-sawed lumber was planned to 4.5 cm thick, 9.0 cm wide and 100cm long. The lumber pieces were assigned to two groups according to their dynamical MOE. FJ lumber is produced by cutting a series of sloping fingers on the end of the wood pieces to be joined and interlocking the two pieces by MDI glue. Bending and tensile strengths of FJ lumber were tested. The results show that the structural performance of the MSR FJ lumber was increased effectively after these units were machine-graded in advance and the interaction of variables should be considered in the design of finger joints.

Résumé :

Genes capable of translating positional information into regulated growth lie at the heart of morphogenesis, yet few genes with this function have been identified. Mutants in the Drosophila four-jointed (fj) gene show reduced growth and altered differentiation only within restricted sectors of the proximal-distal (PD) axis in the leg and wing, thus fj is a candidate for a gene with this coordination function. Consistent with a position-sensitive role, we show that fj is expressed in a regional pattern in the developing leg, wing, eye and optic lobe. The fj gene encodes a novel type II membrane glycoprotein. When the cDNA is translated in an in vitro translation system in the presence of exogenous microsomal membranes, the intralumenal portion of some of the molecules is cleaved, yielding a secreted C-terminal fragment. We propose that fj encodes a secreted signal that functions as a positive regulator of regional growth and differentiation along the PD axis of the imaginal discs.

Résumé :

Introduction Impossibility to place a gastrostomy and failed gastroesophageal reflux surgery with unsafe swallow are the main indications to Feeding Jejunostomy (FJ) in children. The aim of this study is to quantify the incidence of complications associated with FJ. Materials and Methods A retrospective review of patients who had surgically inserted FJ between January 2009 and August 2013 at our institution was conducted. Data were obtained from medical records, operative notes, and radiology database, focusing on complications. Results A total of 19 patients, average age 39.6 months (3–168 months), were treated during the study period. Indications to FJ were gastroesophageal reflux disease (GERD) associated with unsafe swallow in 12, esophageal atresia in 5, and foregut dysmotility in 2. Seventeen FJ were inserted via laparotomy and 2 were laparoscopically assisted. In all cases, a serosal tunnel on the antimesenteric border was fashioned. No intraoperative complications were recorded. Tube dislodgement/blockage occurred on an average of 0.48 times per month in 18 out of 19 patients. The average radiation dose received for tube reinsertion/manipulation was 3.316 mSv/year/patient (0–10.66). Major postoperative complications occurred in 7 out of 19. After an average follow-up of 21 months, two have abandoned the use of FJ due to poor tolerance and three have fully weaned off. Two patients died due to unrelated causes. Conclusion FJ, as an alternative means for enteral feeding, may require multiple readmissions and exposure to radiological procedures. The high risk of severe complications should be considered when offering this procedure.

Résumé :

O objetivo do estudo foi avaliar a aceitabilidade sensorial de cookie adicionado de Farinha de Jenipapo (FJ). Também, determinar a composição físico-química da formulação padrão e daquela contendo maior teor de FJ e com aceitação semelhante ao padrão. Foram desenvolvidas 6 formulações de cookie: F1 (padrão, 0% de FJ) e as demais adicionadas de 3,5% (F2), 5% (F3), 6,5% (F4), 8% (F5) e 9,5% (F6) de FJ. Participaram da avaliação sensorial 70 julgadores não treinados de 7 a 10 anos. A amostra padrão apresentou maior aceitabilidade sensorial (p<0,05) que F6. As demais formulações não tiveram diferença significativa entre si (p>0,05). Maiores teores de cinzas e fibra alimentar, menores de umidade e lipídio e semelhantes de proteína, carboidrato e calorias foram verificados em F5. Conclui-se que um nível de adição de até 8% de FJ em cookie é bem aceito pelas crianças, obtendo-se boas expectativas de comercialização. Além disso, melhora o valor nutricional do produto, especialmente com o aumento no teor de minerais e de fibra alimentar.

Résumé :

At present, methods of bit error rate (BER) analysis for frequency-hopping (FH) system can only solve the problem of barrage jamming, but these are no comprehensive means to follower jamming (FJ). This paper proposes a method of BER analysis with FJ based on frequency hopping M-ary frequency-shift keying (FH/MFSK) system. Through the analysis of the mechanism of FH/MFSK system, assuming the wireless channel is an AWGN channel, the BER formulas for different jamming types are derived, respectively, from the point of one-dimensional probability density function of the output signal of the envelope detector, while judgment principle of envelope detecting method is used. Results show that the BER of multiple FH/MFSK system with FJ is relatively lower. In the worst case of FJ, the BER of FH/4FSK system and FH/8FSK system is reduced by 2 dB and 3 dB, respectively, compared with that of FH/2FSK system. The method of BER analysis proposed provides an effective means to research the BER with FJ in depth.

Résumé :

Abstract Objectives Current infant and young child feeding recommendations include a focus on sugar-containing beverages (SCBs). The American Academy of Pediatrics recommends delaying the introduction of fruit juice (FJ) until after age 12 months and limiting toddler consumption to 4 ounces/day, and the U.S. Dietary Guidelines advise avoiding sugar-sweetened beverages (SSBs) prior to age 2 years. Well-Child Visits (WCV) provide an opportunity to educate parents and promote recommended feeding practices. We aimed to describe the SCB-related knowledge and feeding practices of a sample of parents and the potential for using short videos during WCVs to provide early feeding related education. Methods A convenience sample of parents attending 4–15 month WCVs at a busy metro area clinic in Georgia completed a self-administered survey to assess their infant/young toddler feeding practices and their knowledge of SCB-related feeding recommendations. A sub-sample also reported on their perceptions of a 3-minute educational video viewed during the visit. Results Respondents (n = 105) were primarily women (87%), non-Hispanic/Latino (93%), and Black/African-American (95%). Some parents: 12% and 77% respectively, believed it OK to give infants FJ before 6 months and 12 months of age; 6% reported introducing FJ before 4 months. Among those with children ≥ 12 months (12–18 months; n = 36), 81% reported having given them FJ before 12 months; 25% reported giving them > 4 ounces FJ/day; and 56% had already given their child SSBs. Age of FJ introduction was not modified by presence of older sibling or age of parent. Few (5%) parents were aware of any expert recommendation related to FJ consumption. Most parents who viewed an education video during the WCV (n = 47) reported being able to focus on (74%), enjoy (85%), and learn something (83%) from it; 96% liked the video length, 74% felt watching it was a good use of their time, 45% perceived a change in their thinking after viewing the video. Conclusions Our findings demonstrate that consumption of FJ among infants and SSBs among young toddlers is common, that parents are unaware of expert recommendations related to FJ consumption, and short videos present an opportunity to support parent education efforts during WCVs.

Résumé :

Objetivou-se avaliar a influência das ervas sobre o recrutamento e sobrevivência de plântulas lenhosas em florestas jovem (FJ) e madura (FM) de caatinga. Foram estabelecidas 50 parcelas (1x1m) pareadas (com e sem ervas), distribuídas em cada floresta. Todas as plântulas foram marcadas e o número mensal de novos nascimentos foi registrado. As sobrevivências das coortes de plântulas de todas as parcelas foram quantificadas. Foram registradas 14 espécies de plântulas lenhosas nas florestas. A densidade de ervas foi maior na FJ. Houve diferença no total de plântulas lenhosas entre as florestas e diferença nos nascimentos e mortes entre as parcelas com e sem ervas na FJ. Nas duas florestas, mortalidade tendeu a ser maior nos meses da estação chuvosa. Houve relação de dependência entre densidade de ervas e densidade de regenerantes lenhosos na FJ e na FM. Em ambas as florestas, a sobrevivência das coortes de plântulas foi maior quando o recrutamento ocorreu no início da estação chuvosa. Os resultados sugerem que na FJ, a interação erva-plântula parece ser de competição, enquanto na FM a interação parece ser de facilitação, resultando em maior recrutamento e a sobrevivência das coortes na presença das herbáceas.

Résumé :

In the laboratory, an acaricide-susceptible strain of the citrus red mite, Panonychus citri (McGregor) (LS-FJ), was used to screen for resistance to spirotetramat. A spirotetramat-resistant strain (ST-NK) obtained after continuous selections through 15 selection cycles (45 generations) exhibited 1668.4-fold greater resistance when compared to the parent generation. Instability of the spirotetramat resistance in the mites was observed during 11 months under spirotetramat-free laboratory conditions. Cross-resistance to spirodiclofen and spiromesifen was detected both in eggs and larvae, but not to five other tested acaricides. Probit lines for F1 heterozygous progeny indicated that the resistance to spirotetramat in the mites was autosomal with neither sex linkage nor maternal effects. The degrees of dominance were 0.15 and 0.23 for the diploid F1 of LS-FJ♀ × ST-NK♂ and ST-NK♀ × LS-FJ♂, and 0.07 and 0.13 for haploid F2 of LS-FJ♀ × ST-NK♂ and ST-NK♀ × LS-FJ♂, respectively, which indicated that the resistance was incompletely dominant. The χ2 analyses from the response of a backcross of crossed F1 progeny and ST-NK and F2 progeny showed that multiple genes are responsible for resistance to spirotetramat.

Résumé :

This study examined consumption proportions and factors associated with sugar-sweetened beverages (SSBs), artificially sweetened beverages (ASBs), and 100% fruit juice (FJ) consumption. We recruited Non-Hispanic Black (n = 136) and White (n = 192) low-income overweight or obese pregnant women aged 18 to 46 years (mean = 25.7 years) from the Special Supplemental Nutrition Program for Women, Infants, and Children clinics in Michigan, USA. Independent variables included weight status, trimester, smoking, stress, education, employment, race, and age. Dependent variables were high (consuming ≥ 1 serving/day) versus low consumptions of SSB, ASB, and 100% FJ. Multivariate logistic regression modeling was performed to examine factors associated with beverage consumption. Out of the sample, 48.2%, 6.7%, and 31.3% reported high SSB, ASB, and 100% FJ consumption, respectively. SSB consumption was associated with smoking (OR: 3.77, p < 0.001), education (OR: 0.57, p = 0.03), and race (OR: 1.69, p = 0.03). Artificially sweetened beverage consumption was not associated with any factors examined. One hundred percent FJ consumption was associated with stress (OR: 0.90, p = 0.03) and race (OR: 4.48, p < 0.001). Clinicians may advocate for reductions in SSB and 100% FJ consumption tailored to client consumption characteristics.

Résumé :

The outbreaks of pseudorabies have been frequently reported in Bartha-K61-vaccinated farms in China since 2011. To study the pathogenicity and evolution of the circulating pseudorabies viruses in Fujian Province, mainland China, we isolated and sequenced the whole genome of a wild-type pseudorabies virus strain named “FJ-2012.” We then conducted a few downstream bioinformatics analyses including phylogenetic analysis and pathogenic analysis and used the virus to infect 6 pseudorabies virus-free piglets. FJ-2012-infected piglets developed symptoms like high body temperature and central nervous system disorders and had high mortality rate. In addition, we identified typical micropathological changes such as multiple gross lesions in infected piglets through pathological analysis and conclude that the FJ-2012 genome is significantly different from known pseudorabies viruses, in which insertions, deletions, and substitutions are observed in multiple immune and virulence genes. In summary, this study shed lights on the molecular basis of the prevalence and pathology of the pseudorabies virus strain FJ-2012. The genome of FJ-2012 could be used as a reference to study the evolution of pseudorabies viruses, which is critical to the vaccine development of new emerging pseudorabies viruses.

One of the important disease that very detrimental to kenaf is Fusarium wilt caused by Fusarium oxysporum Schlecht. The purpose of this study was to evaluate the response of 70 kenaf germplasms accessions against F. oxysporum. The study was conducted at the Phytopatology Laboratory and screen house of Indonesian Sweetener and Fiber Crops Research Institute, Malang using completely randomized design with three replicates. Seventy accessions and one resistant accession as control (1267 (BG-52-135) were used in this study. Inoculation of Fusarium was done 7 days after sowing (das) by sprinkling 100 ml of spore suspension into the soil. Observation of disease intensity started at 10–40 days after inoculation (dai) and repeated every five days. Percentage of stalk discolorization was estimated at 50 dai. The results showed that accession 1040 (FJ/017) had the lowest disease intensity (0.83%), hence was categorized as a highly resitant accession. Fourteen accessions were categorized as resistant with disease intensity below or equal to 10%; 28 accessions were moderate resistant; and 27 accessions were susceptible. FJ/017 (the highset resistant accession) and 14 resis-tant accessions (1064(SUC/012), 1061(SRB/082), 1035(FJ/005), 839(PARC/2709), 955(FJ/003), 842(PARC/ 2712), 1095(SUC/003), 838PARC/2708), 957(FJ/007), 1065(SUC/023), 1042(CHN/056), 145(BL/118), 1036 (FJ/006), dan 778(PARC/2466)) could be used as resistant genetic sources in developing new varieties.

Résumé :

The chiral boson actions of Floreanini and Jackiw (FJ), and of McClain, Wu and Yu (MWY) have recently been shown to be different representations of the same chiral boson theory. MWY displays manifest covariance and also a (gauge) symmetry that is hidden in the FJ side, which, on the other hand, displays the physical spectrum in a simpler manner. We make use of the manifest covariance of the MWY chiral boson representation to couple it to background gravity showing explicitly the equivalence with the previous results for the FJ representation.

Résumé :

The fruit of Kersen or cherry (Muntingia calabura), a popular shade tree, is not yet promoted as a marketable fruit or a healthy herbal drink. This study aimed to investigate potential health benefits of fruit juice and crude extract of the fruit pulp of M. calabura including their antioxidant potential and inhibitory activities on several enzymes related to metabolic disorders. Fresh juice (FJ) of M.calabura fruit was obtained by juice extractor, whereas the fruit pulp (FP) was dried and macerated with ethanol to obtain the crude extract. Both were evaluated for their inhibitory activities against α-glucosidase, α-amylase, xanthine oxidase, lipase, and protease. Antioxidant activity was evaluated based on their scavenging activity on 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radicals. Both FJ and FP showed good antidiabetic activity by inhibiting α-glucosidase (IC50 162.00 and 84.70 µg/mL, respectively) and α-amylase (IC50 422.34 and 80.46 µg/mL, respectively). In comparison, IC50 of acarbose on α-glucosidase and α-amylase were 130.66 and 152.46 µg/mL, respectively. The FJ and FP extract showed anti-hyperuricemia activity by inhibiting xanthine oxidase (0.02 and 2.78 mg allopurinol equivalent/mL for FJ and FP, respectively). However, weak inhibition activities on protease and lipase were observed for the FJ and FP extract compared to the references used. Similarly, FJ and FP exhibited weak scavenging activity on DPPH, when compared with BHT and ascorbic acid. The study recommends the fruit of M.calabura as a potential source of antidiabetic and anti-hyperuricemia agents. The fruit can be further explored for nutraceutical applications.

It was found that there were some kinds of sulfur-oxidizing bacteria in the acidic mine water, and these bacteria could promote the dissolution behavior of heavy metals in the mining smelting waste slags. In this paper we collected a bacterium sample form a mining-water of an abandoned pyrite mine in the southwest of China and named it as FJ strain. We isolated and purified the FJ strain by 9K medium, and then made a primary identification of the purified strain. The FJ strain was gram-negative and in the shape of short rod. The strain was chemoautotrophic and aerobic bacterium, and it could oxidize the ferrous ion or the reduced sulfur as energy source to main the metabolism. The optimum growth temperature and pH is 30 °C and 2.0 separately. And we also found the strain had a considerable acid-producing ability and was eosinophilic. After a comparison and analysis, we confirmed that the physiological and biochemical characteristics of the isolated FJ strains were consistent with that of thiobacillus ferrooxidans, T ferroxidans for short. Therefore we drew a conclusion that the FJ strain we purified was just the target strains T ferrooxidans, the isolation-purification of the bacterium sample was successive.

Résumé :

An emerging pseudorabies virus (PRV) variant has been reported on Bartha-K61-vaccinated farms since 2011, causing great economic losses to China’s swine-feeding industry. In this study, two vaccines, FJ-2012ΔgE/gI-GEL02 and FJ-2012ΔgE/gI-206VG, were administered to piglets for immune efficacy investigation. Humoral immunity response, clinical signs, survival rate, tissue viral load, and pathology were assessed in piglets. The results showed that both vaccines were effective against the PRV FJ-2012 challenge, the piglets all survived while developing a high level of gB-specific antibody and neutralizing antibody, the virus load in tissue was alleviated, and no clinical PR signs or pathological lesions were displayed. In the unimmunized challenged group, typical clinical signs of pseudorabies were observed, and the piglets all died at 7 days post-challenge. Compared with commercial vaccines, the Bartha-K61 vaccine group could not provide full protection, which might be due to a lower vaccine dose; the inactivated vaccine vPRV* group piglets survived, displaying mild clinical signs. The asterisk denotes inactivation. These results indicate that FJ-2012ΔgE/gI-GEL02 and FJ-2012ΔgE/gI-206VG were effective and could be promising vaccines to control or eradicate the new PRV epidemic in China.

Résumé :

Although extensive efforts have been dedicated to investigating the risk factors of low back pain in the workplace, a clear knowledge of their effects on the facet joint (FJ) mechanics is lacking. In this study, fourteen healthy participants performed dynamic lifting task with varying external load while a dynamic stereo-radiography system captured their lumbar motion continuously. The FJ kinematics in the lumbar spine were ascertained using a volumetric model-based tracking method. The FJ kinematics data from seven participants were processed and analyzed using non-parametric statistical test. The results indicated significant (p<0.05) effects of external load on the FJ flexion and superior-inferior translation at all segments, showing more consistent trends at the L2-L3, L3-L4, and L4-L5 joints during trunk flexion angles of approximately 20° and 40°. Findings of this study provide a preliminary but important foundation in elucidating facet-related injury mechanism due to strenuous exertions in workplaces.

AbstractObjectiveTo examine the contribution of 100 % fruit juice (FJ) consumption to dietary adequacy of shortfall nutrients by children and adolescents.DesignCross-sectional.SettingSecondary analysis of data from the 2003–2006 National Health and Nutrition Examination Survey (NHANES).SubjectsChildren and adolescents aged 2–18 years (n 7250). Usual intake, determined from two 24 h dietary recalls, was calculated using the National Cancer Institute method. The population was dichotomized into consumers or non-consumers of 100 % FJ. The age/gender-specific percentage of the two consumption groups with intakes less than the Estimated Average Requirement or that exceeded the Adequate Intake for selected nutrients was determined. A Z-statistic for differences in population proportions was used to determine significance (P < 0·05).ResultsChildren aged 2–5 years had the highest percentage of 100 % FJ consumers (71·1 %), followed by children aged 6–12 years (57·0 %) and adolescents aged 13–18 years (44·5 %). Compared with 100 % FJ consumers, a significantly higher percentage of non-consumers had intakes below the Estimated Average Requirement for vitamin A (24·4 (se 2·5) % v. 42·2 (se 2·5) %), vitamin C (0·1 (se 0·2) % v. 38·9 (se 4·1) %), folate (8·8 (se 1·5) % v. 22·1 (se 2·4) %), P (11·6 (se 2·1) % v. 21·3 (se 2·6) %) and Mg (25·8 (se 1·7) % v. 46·1 (se 2·0) %). A greater percentage of 100 % FJ consumers exceeded the Adequate Intake for K (2·4 (se 0·5) v. 0·5 (se 0·2) %) compared with non-consumers.ConclusionsConsumption of 100 % FJ is associated with improved nutrient adequacy and can contribute to a healthy diet.

ObjectivesWe recently identified microRNA-181a-5p (miR-181a-5p) as a critical mediator involved in the destruction of lumbar facet joint (FJ) cartilage. In this study, we tested if locked nucleic acid (LNA) miR-181a-5p antisense oligonucleotides (ASO) could be used as a therapeutic to limit articular cartilage degeneration.MethodsWe used a variety of experimental models consisting of both human samples and animal models of FJ and knee osteoarthritis (OA) to test the effects of LNA-miR-181a-5p ASO on articular cartilage degeneration. Histopathological analysis including immunohistochemistry and in situ hybridisation were used to detect key OA catabolic markers and microRNA, respectively. Apoptotic/cell death markers were evaluated by flow cytometry. qPCR and immunoblotting were applied to quantify gene and protein expression.ResultsmiR-181a-5p expression was increased in human FJ OA and knee OA cartilage as well as injury-induced FJ OA (rat) and trauma-induced knee OA (mouse) cartilage compared with control cartilage, correlating with classical OA catabolic markers in human, rat and mouse cartilage. We demonstrated that LNA-miR-181a-5p ASO in rat and mouse chondrocytes reduced the expression of cartilage catabolic and chondrocyte apoptotic/cell death markers in vitro. Treatment of OA-induced rat FJ or mouse knee joints with intra-articular injections of in vivo grade LNA-miR-181a-5p ASO attenuated cartilage destruction, and the expression of catabolic, hypertrophic, apoptotic/cell death and type II collagen breakdown markers. Finally, treatment of LNA-miR-181a-5p ASO in cultures of human knee OA chondrocytes (in vitro) and cartilage explants (ex vivo) further demonstrated its cartilage protective effects.ConclusionsOur data demonstrate, for the first time, that LNA-miR-181a-5p ASO exhibit cartilage-protective effects in FJ and knee OA.

Résumé :

AbstractLet Mm be an m-dimensional, closed and smooth manifold, equipped with a smooth involution T : Mm → Mm whose fixed point set has the form Fn ∪ Fj, where Fn and Fj are submanifolds with dimensions n and j, Fj is indecomposable and n > j. Write n – j = 2pq, where q ≥ 1 is odd and p ≥ 0, and set m(n– j) = 2n + p–q +1 if p ≤ q +1 and m(n– j) = 2n +2p–q if p ≥ q. In this paper we show that m ≤ m(n – j) + 2j + 1. Further, we show that this bound is almost best possible, by exhibiting examples (Mm(n–j)+2j, T) where the fixed point set of T has the form Fn ∪ Fj described above, for every 2 ≤ j < n and j not of the form 2t – 1 (for j = 0 and 2, it has been previously shown that m(n – j) + 2 j is the best possible bound). The existence of these bounds is guaranteed by the famous 5/2-theorem of J. Boardman, which establishes that under the above hypotheses .

Résumé :

We analyzed the visual functions of two patients (MS, FJ) with bilateral lesion of the primary visual cortex, which occurred at gestational age 33 wk in MS and at postnatal month 7 in FJ. In both patients basic visual functions— visual acuity, contrast sensitivity, color, form, motion perception—are similarly preserved or modestly impaired. Functions requiring higher visual processing, particularly figure-ground segregation based on textural cues, are severely impaired. In MS, studied longitudinally, the deficits attenuated between the ages of 4.5 and 8 y, suggesting that the developing visual system can display a considerable degree of adaptive plasticity several years after the occurrence of a lesion. In FJ (age 18:9 to 20:6 y), who is more impaired, the recovery, if any, was less.

Résumé :

This case describes how Fujian CTS Group, a state-owned company in Fujian Province, China, transformed from a company suffering from three consecutive years of losses to a profitable conglomerate through strategic restructuring. This case focuses on the whole process of strategic restructuring, including the background of the restructuring, the formulation and implementation of the strategic restructuring plan, as well as the results of the restructuring. FJ CTS group was founded in December 1949 as “Xiamen Overseas Chinese Service”, known as the first travel agency of PR China. After 60 years of development, Fujian CTS Group has developed into a conglomerate with core businesses of travel service, hotel, and tour bus. With the rapid development of China's tourism industry and quick change of business environment, Fujian CTS Group faced fierce competition from many domestic and foreign tourism enterprises, and the company had suffered from three consecutive years of losses since 2003. At the end of 2005, in order to get the company out of financial difficulties and achieve profitability, the board of directors of the group started to work on strategic restructuring program. At the end of 2006, the restructuring plan was completed. In early 2007, the group began the implementation of restructuring plan. Since then, with two years' great efforts, the restructuring of the group had been completed successfully. The company's overall revenue rose steadily, operating performance greatly improved. Until the end of 2009, the total assets of the group reached 13.52 billion Chinese yuan and the three core businesses (travel service segment, hotel segment, and tour bus segment) of the group all achieved good financial performance. The group has achieved turnaround through effective restructuring.

Résumé :

An understanding of the leaf and root traits associated with high nitrogen (N) absorption and utilization is very important in the development of N-efficient varieties in crop breeding programs. However, in rice, the relations between these traits and nitrogen use efficiencies (NUEs) have yet to be identified. Therefore, the responses of leaf and root traits and yields of the three main japonica rice cultivars in northern China were examined at a range of N application rates. The rice cultivars, Shennong 265 (SN265), Tiejing 11 (TJ11), and Fengjing (FJ), were grown in the field at six N rates (0, 60, 120, 180, 240, and 300 kg ha−1) applied during two growing seasons (2018 and 2019). With the increase in N rate, the grain yield of SN265 and TJ11 increased, whereas the grain yield of FJ first increased and then decreased. The grain yield of FJ was higher than that of SN265 and TJ11 at lower N rates, whereas the grain yields of SN265 and TJ11 were higher than that of FJ at higher N rates. The NUEs decreased with the increase in N rates. At lower N rates, the ability of rice to obtain N was the main limitation on rice yield, but with the increase in N rates, the limitation on yield due to N absorption capacity gradually weakened. However, at higher N rates, rice yields were restricted by the ability to utilize N. Compared with TJ11 or FJ, SN265 had higher N utilization capacity primarily because of its higher Rubisco activity, NR activity, GS activity, and ROA. Compared with SN265 or TJ11, FJ had a higher N absorption capacity that was attributed to its larger root architecture, which might have also been one of the reasons for lower N utilization. Therefore, by improving N absorption and utilization-related leaf and root traits, high yields and NUEs can be achieved in rice production at different N application rates.

Résumé :

A generalized shadowing lemma is used to study the generation of Benford sequences under non-autonomous iteration of power-like maps Tj : x ↦ αjxβj (1 - fj(x)), with αj, βj > 0 and fj ∈ C1, fj(0) = 0, near the fixed point at x = 0. Under mild regularity conditions almost all orbits close to the fixed point asymptotically exhibit Benford's logarithmic mantissa distribution with respect to all bases, provided that the family (Tj) is contracting on average, i.e. [Formula: see text]. The technique presented here also applies if the maps are chosen at random, in which case the contraction condition reads 𝔼 log β > 0. These results complement, unify and widely extend previous work. Also, they supplement recent empirical observations in experiments with and simulations of deterministic as well as stochastic dynamical systems.
