Objective. Patients with anti-Jo-1 antibodies (Abs) and anti–melanoma differentiation-associated protein 5 (MDA5) Abs are at a higher risk of interstitial lung disease (ILD) and have a mortality rate higher than that of patients with anti-Jo-1 Abs. This study investigated differences in the clinical characteristics and prognosis of patients with anti-Jo-1 Abs and anti-MDA5 Abs with dermatomyositis (DM). Methods. We retrospectively reviewed the medical records of 38 patients with DM from January 2000 to December 2021. The patients were divided into anti-Jo-1 Abs and anti-MDA5 Abs groups. The basic demographic data, clinical manifestations, and 1-year mortality rates of the groups were compared. Results. Among the 38 patients, 30 were anti-Jo-1-Abs positive and 8 patients were anti-MDA5 Aba positive. The patients with anti-MDA5 Abs presented with more apparent cutaneous symptoms and aggressive pulmonary manifestations than did those with anti-Jo-1 Abs. The mortality rate in the anti-MDA5 Abs group (1.95/person-year (PY)) was much higher than that in anti-Jo-1 Abs group (0.094/PY), and most of the mortalities occurred within the first 1–3 months of follow-up. Conclusion. Distinct cutaneous and pulmonary manifestations were observed in the anti-Jo-1 Abs and anti-MDA5 Abs groups. The mortality rate in the anti-MDA5 Abs group was significantly higher than that in the anti-Jo-1 Abs group. Early recognition is crucial to ensuring higher chances of survival for patients with anti-MDA5 Abs.

Abstract Paternal transmission of the bithorax-complex (BX-C) rearrangement, inversion Uab1, causes a specific dominant gain of function phenotype in most abdominal segments. This represents a case of paternal imprinting since the mutant phenotype will occur only if inversion Uab1 is paternally transmitted. The transformations in males are toward genital arch tissue. For females the transformations are to tissue found on abdominal segment 7 (Ab7) and to structures normally restricted to the genital disc. Ninety-six percent of transformed areas appear on Ab5 and Ab6 in both sexes and on Ab7 in females, coinciding with the Abd-B domain. Four percent of the transformations occurred on Ab1 through Ab4, coinciding with the abd-A domain. The mutant phenotype can be dramatically enhanced by modifying genes such as the posterior BX-C mutant tuh-3. Expressivity is modulated by maternal effect alleles interacting with tuh-3. A region of function within inversion Uab1 appears to be programmed during spermatogenesis to function in a legacy dependent manner during embryogenesis.

Streszczenie:

Recently, a new type of automatic ball balancer (ABB), called the ball-spring autobalancer (AB), has been proposed, which substantially eliminates the drawbacks of the traditional ABBs. In previous studies, the dynamics of the Jeffcott planar rotor equipped with ball-spring AB has been investigated. In the Jeffcott model, it is assumed that the ABB is located on the plane of the unbalance disk. However, for the non-planar rigid rotor with distributed imbalances, out-of-plane motions may occur, and the Jeffcott model becomes unreliable as the tilting motion cannot be explained. To this end, the aim of this paper is to analyze the capability of the ball-spring AB in balancing non-planar rotors and to reconfirm its pre-claimed advantages over the traditional ABBs for balancing non-planar rotors. To start, the mathematical model of the rigid rotor with two ball-spring ABs is established, based on which the nonlinear equations of motion are derived. Then, the system time responses are computed numerically and the balanced stable regions are acquired by the Lyapunov’s first method. The results of this study show that the ball-spring ABs can balance the non-planar rotors and the tilting motion does not impair the pre-claimed advantages of the ball-spring AB.

Innate immunity natural Abs (NAbs) execute a number of functions, including protection and surveillance. Despite active research, the stimuli that induce the formation of NAbs are still described only hypothetically. Here, we compared repertoires of anti-glycan Abs in the peripheral blood of mice that received per os various bacteria. The repertoires of Abs of mice primed in this way were compared using a microarray that included about 350 glycans, as well as 150 bacterial polysaccharides. Sterile mice did not possess anti-glycan Abs. Oral inoculation of a single strain or combination of two to four strains of bacteria, as well as putting the animals on short-term nutrition with non-sterile food, did not contribute significantly to the formation of Abs, whereas a single gavage of digested food of non-sterile mice induced the formation of a repertoire close to the natural ones. Interestingly, the priming with polysaccharide Ags (in a composition of the bacterial cell envelope), that is, dominant Ags of bacteria, led to the induction of Abs against typical glycans of mammalian glycoproteins and glycolipids (e.g. Abs of the ABH blood group system) that do not have a structural similarity to the polysaccharides. The results support the importance of early contact with a naïve immune system with microorganisms of the environment to form a normal NAbs repertoire.

Abstract We previously showed that anti-idiotypic mAb (mAb2) F16-16D7 (16D7) to the paratope (or paratope-related idiotope) of the anti-CD4 mAb HP2/6 induces anti-CD4 Abs in BALB/c mice. In view of the potential ability of 16D7 to induce anti-CD4 Ab in humans and the potential benefits of anti-CD4 Abs in the treatment of autoimmune diseases, we evaluated the immunologic response to and assessed the safety of four 2-mg 16D7 s.c. injections in one patient with systemic lupus erythematosus (SLE) and one with rheumatoid arthritis (RA). 16D7 induced anti-isotypic and anti-anti-idiotypic Abs (Ab3), which were almost exclusively of the IgG isotype. Ab3 specifically reacted with 16D7 as they inhibited its binding to mAb HP2/6. Although Ab3 did not react with cellular or recombinant CD4 (rCD4), single-cell enzyme-linked immunospot assays of anti-CD4 Ab production revealed many more spot-forming cells in rCD4- and 16D7-coated wells than in wells coated with BSA or 16D7 isotype-matched MK2-23. Spot-forming anti-CD4 Abs were specifically induced by 16D7, since rCD4-dependent spot formation 1) was not observed with PBL from one patient with SLE, one with mixed connective tissue disease, and one with melanoma immunized with MK2-23; and 2) was inhibited by 16D7 and not by MK2-23. Spot-forming anti-CD4 Abs recognize a CD4 epitope identical (or closely related) to that seen by HP2/6, since this specifically inhibited spot formation. A substantial, although transient, CD4+ T cell depletion was only observed in the RA patient. Local and/or general toxicity and laboratory and/or clinical signs indicative of immunodepression or diseases relapse were not observed during an 18-month follow-up.

Streszczenie:

Acrylonitrile-butadiene-styrene (ABS) is one of the most widely used plastic. The application of ABS increases rapidly in industries recently. The drawback of the increasing demand of ABS is the increment of ABS waste. Huge increment in ABS waste has led to the increasing of environmental pollution. The demand in green technology and sustainability of resources has urged the need of recycling of ABS waste. However, the mechanical properties of the recycled ABS are deteriorated. Hence, this work aims to study the mechanical properties of blend virgin and recycled ABS. The first sample started with 100wt% of virgin ABS. While the second to eleventh samples was a mixing of virgin and recycled ABS at 10wt% incremental recycled ABS. The last sample was prepared using 100wt% of recycled ABS. The results show that the tensile strength of 100wt% of recycled ABS is slightly decreased as compared to 100wt% virgin ABS. Similar trend was observed on traverse rupture strength (TRS) when the TRS for 100wt% of recycled ABS is lower by 8% when compared to 100wt% of virgin ABS. The most significant change is observed on the impact strength. The impact strength for 100wt% of recycled ABS is substantially dropped by 86% as compared to 100wt% of virgin ABS.

Abstract Polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) were blended by varying ABS content. The thermal, mechanical and tribological properties of the PC/ABS blends were systematically characterized. Increasing ABS content in the PC/ABS blends decreased thermal stability of the blends, as a result of the lower thermal stability of the ABS than that of the PC. Although the tensile strength of the PC/ABS blends apparently decreased with increased ABS content, the PC/ABS blend with 10 wt% of ABS had the highest tensile strength, because of improved processability of the blend. The friction and wear of the ABS measured against a steel ball of 6 mm in diameter were higher than those of the PC. As a result, a higher ABS content in the PC/ABS blends resulted in higher friction and wear of the blends. The scratch results showed that scratching with a 5 mm steel ball generated a scratch with a shorter length and lower depth on the PC than on the ABS, which indicated better scratch resistance of the PC. Therefore, the PC/ABS blend with 50 wt% of PC had better scratch resistance than the ABS, due to the influence of the PC embedded in the blend.

ABS filament remains an important feeding material for fused deposition manufacturing (FDM). However, ABS tends to experience warping after printing. The current paper investigates the effect of hBN fill on rheology property and diameter of ABS extrudate. ABS filled hBN composite was prepared by a facile solution mixing method. Rheological characterisation by capillary rheometer shows that ABS filled 5 wt% hBN composite exhibited a higher shear viscosity than the pure ABS. hBN addition appears to increase the shear viscosity of ABS by 62% at the shear rate of 200 s-1, but the increase was reduced to 20% at 1000 s-1. ABS-hBN extrudate surface microstructure deteriorated lesser than ABS extrudate when the shear rate increased up to 1000s-1. SEM micrograph of ABS-hBN extrudate’s surface exhibited less sharkskin feature but its swell percentage is 5.4% higher than the ABS extrudate. The addition of hBN fillers resulted in higher shear viscosity and percentage of ABS die swell but exhibited less sharkfin feature (smoother surface) on extrudate surface than the pure ABS.

With the aim of invesgating effect of the two polymer phases of ABS on improved fire performance of ABS filled with magnesium hydroxide, we have prepared ABS filled with surface-treated magnesium hydroxide (MH) via compounding poly (styrene-acrylonitrile) (SAN) and polybutadiene filled with MH as well as by compounding ABS and MH. These ABS filled with MH were compared with unfilled ABS by investigating their fire performance and thermal degradation with LOI test, UL-94 test, DSC and FTIR. The dehydration of MH did not effectively increase fire performance and thermal stability of ABS filled with 60.0wt% MH when MH resided in SAN of ABS due to compounding of ABS and MH. The dehydration of MH was clearly able to change the decomposition behavior of the two polymer phases of ABS in ABS filled with 60.0wt% MH when MH resided in the polybutadiene of ABS, resulting in an efficient enhancement of fire performance.

The effects of polypropylene-graft-maleic anhydride (PP-g-MA) compatibilizers on the morphology and mechanical properties of polyoxymethylene (POM)/acrylonitrile-butadiene-styrene (ABS) blends were investigated. Two types of compatibilizers, PP-g-MA with maleic anhydride 0.50 wt% (PP-g-MA1) and PP-g-MA with maleic anhydride 1.31 wt% (PP-g-MA2) were used to study the interfacial adhesion of POM and ABS. POM/ABS blends with and without PP-g-MA compatibilizer were prepared by an internal mixer and molded by compression molding. Scanning electron microscope (SEM) was used to investigate the morphology of ABS phase in POM matrix. The results found that POM/ABS blends clearly demonstrated a two phase separation of dispersed ABS phase and the POM matrix phase, and ABS phase dispersed as spherical domains in POM matrix in a range of ABS 10-30 wt% and the blends containing ABS more than 30 wt% showed the elongated structure of ABS phase. The addition of PP-g-MA could improve the interfacial adhesion of POM/ABS blends due to the domain size of ABS phase decreased after adding PP-g-MA. The mechanical properties showed that the impact strength of POM/ABS blends decreased in a range of 10-20 wt% and did not change after 20 wt%. The addition of PP-g-MA did not change the impact strength of POM/ABS blends. The Young’s modulus of POM/ABS blends increased up to 30 wt% of ABS and then decreased. While the blends showed the decrease of tensile strength and percent strain at break with increasing ABS content. The addition of PP-g-MA increased the tensile strength of POM/ABS blends in a range of 30-40 wt% of ABS. The above results indicated that the morphology had an effect on the mechanical properties of polymer blends.

Mechanical and morphological properties of acrylonitrile-butadiene-styrene (ABS)/zinc oxide (ZnO) nanocomposites used ethylene-vinyl acetate copolymer (EVA) as compatibilizer were investigated. The ABS/ZnO nanocomposites without and with EVA 4 wt% were prepared by melting-blend with an internal mixer. The results showed that the addition of ZnO nanoparticles did not improve the mechanical properties of ABS/ZnO nanocomposites. The impact strength of the ABS/ZnO nanocomposites decreased with increasing ZnO content. The addition of EVA in ABS showed a decrease the impact strength but increased after adding ZnO in ABS/EVA matrix. The ABS/ZnO nanocomposites with EVA was higher the percent strain at break, but lower Young’s modulus, tensile strength and impact strength than the neat ABS and ABS/ZnO nanocomposites. The percent strain at break of ABS/ZnO nanocomposites increased with incorporation of EVA all ZnO compositions. However, the poor compatibility between ethylene in EVA and ABS matrix reduced as most of the mechanical properties of ABS/EVA/ZnO nanocomposites. The ZnO particle distributions in nanocomposites were studied by scanning electron microscopy (SEM), which observed that ZnO particles agglomerated in ABS and ABS/EVA matrix. The fractured surfaces of impact test samples were also observed through SEM and revealed that the ductile fracture of ABS was converted to brittle fracture with addition of ZnO.

The effects of styrene-co-maleic anhydride (SMA) compatibilizer on the mechanical thermal and morphological properties of polyoxymethylene (POM)/acrylonitrile-butadiene-styrene (ABS) blends were inverstigated. POM/ABS blends without and with SMA compatibilizer were prepared by an internal mixer and molded by compression molding. It was found that the dispersion of ABS phase and compatibility could not improve by using SMA compatibilizer in POM/ABS blends due to SMA can be miscible with ABS phase more than POM phase. The addition of ABS in a range of 10-30 wt% could improve the Young’s modulus of POM. Impact strength, tensile strength and percent strain at break of POM/ABS blends decreased with increasing ABS content. The addition of compatibilizer improved Young’s modulus of POM/ABS (60/40, 50/50) blends. The addition of ABS increased the degradation temperature of POM, while SMA compatibilizer did not improve the degradation of POM/ABS blends.

Abstract Glanzmann’s Thrombasthenia (GT) is an autosomal recessive inherited platelet function disorder that is due to defect platelet aggregation in response to multiple physiologic agonists. The defect may be because of mutations in the genes encoding either ITGA2B or ITGB3 that result in qualitative or quantitative abnormalities of the platelet receptor aIIbb3. A total of 45 unrelated GT patients were analyzed for mutations in all the exons of ITGA2B and ITGB3 genes by a mutation screening technique, Conformation Sensitive Gel Electrophoresis (CSGE). Mutation was identified in 36 out of 45 patients; and in 9 patients no causative gene alterations were identified in both the genes. Only polymorphisms were identified in 5 patients; however, 4 patients did not show any sequence variation in both the genes. Though their mutation status was not identified, their hematological parameters, platelet aggregation, flow cytometry and western blot revealed that they were definite GT (Table 1). Of these 9 patients with no mutations, 5 patients had family history of bleeding; that included death episode, due to prolonged bleeding in all four families and bleeding complication in sibling in one family. The clinical manifestations included epistaxis, Gum bleeding and petechiae in 8 patients and Echymotic spots in 6 patients. The major bleeding complication of gastro- intestinal bleed and eye bleed was seen in 4 patients and 2 patients respectively; one patient had hematuria. Among the 9 patients with no mutation, a blood transfusion was required in 8 patients. Normal values of Prothrombin time, Activated partial thromboplastin time and platelet count in these patients excluded the possibility of other factor deficiencies and thrombocytopenia. Platelet aggregation was absent with all the four agonists in all these patients. Platelet aIIbb3 analysis by flow cytometry classified 5 patients as type I, one as type II and 3 patients as type III GT. Western blot analysis revealed complete absence of both aIIb and b3 in 6 patients. In remaining 3 patients, one had trace amount of aIIb and reduced amount of b3; another had mild amount of b3 with no trace of aIIb, the third patient had abnormal aIIb protein. GT in these 9 patients may be due to defect in a regulatory element affecting the transcription of these two genes or abnormalities in mechanisms that are responsible for post-translational modifications and trafficking of integrin subunits. Moreover, the strategy to detect mutations in these patients was based on CSGE, whose sensitivity is not 100%. Even though the CSGE technique was carefully set up and tested with known mutations, making it unlikely that nucleotide substitutions were missed in these patients, the literature reports that the sensitivity of the CSGE technique is approximately 80%.

Abstract We have been investigating the generation of specific immune responses using monoclonal anti-idiotypic Abs (Ab2) as surrogate tumor Ag. We have prepared a series of idiotypic mAbs (Ab1) from CBH/cbi rats bearing the syngeneic sarcoma HSN and have used these Ab1 to generate autologous Ab2. By using the autologous Ab2 as Ag, we have isolated T cell lines from CBH/cbi rats that proliferate specifically in the presence of the Ab2, with spleen cells as APC. Specific proliferation of the T cells was prevented if the spleen cells used for presentation were irradiated with conventional doses of x-rays (1000 rad) just before use. Titration of the radiation response showed that the capacity of the spleen cells to present Ag decreased exponentially with x-ray doses of up to 100 rad, at which dose presentation was virtually abolished. The same irradiated spleen cells were fully competent to present OVA to CBH/cbi-derived rat T cell lines specific for this Ag. Preincubating the APC with Ag before irradiation abrogated the effect of x-irradiation on the presentation of Ab2. We conclude that, in this rat system, the presentation of autologous Ab2 is highly sensitive to the effects of low doses of x-rays. The clinical significance of these findings is discussed.

According to the brake characteristics of in-wheel motor drive electric vehicles, and basing on threshold control method, we describe one kind of composite ABS control theory about electric motor ABS combined with hydraulic friction ABS, and establish a co-simulation vehicle model. The composite ABS control method is a control method that the electric motor ABS control works together with the hydraulic ABS control. Both of the two modes of ABS control logic were using logic threshold control method. The model of the in-wheel motor drive electric vehicle was established with AMESim, and the model of the composite ABS controller was built with Simulink. The control performance of composite ABS in different braking strength and different road friction coefficients is simulated. Co-simulation was carried out. Through analysis, a number of parameters curves were obtained. It proves that the composite ABS control method for in-wheel motor drive electric vehicles can effectively control the slip rate, and ensure braking stability.

Classical antagonistic antibodies (Abs) targeting PD-1, such as pembrolizumab and nivolumab, act through blockade of the PD-1–PDL-1 interaction. Here, we have identified novel antagonistic anti–PD-1 Abs not blocking the PD-1–PDL-1 interaction. The nonblocking Abs recognize epitopes on PD-1 located on the opposing face of the PDL-1 interaction and overlap with a newly identified evolutionarily conserved patch. These nonblocking Abs act predominantly through the CD28 coreceptor. Importantly, a combination of blocking and nonblocking Abs synergize in the functional recovery of antigen-specific exhausted CD8 T cells. Interestingly, nonblocking anti–PD-1 Abs have equivalent antitumor activity compared with blocker Abs in two mouse tumor models, and combination therapy using both classes of Abs enhanced tumor suppression in the mouse immunogenic tumor model. The identification of the novel nonblocker anti–PD-1 Abs and their synergy with classical blocker Abs may be instrumental in potentiating immunotherapy strategies and antitumor activity.

The present study investigated the effects of untreated (UM) and treated (TM) muscovite fillers on the morphological and thermal properties of acrylonitrile-butadiene-styrene (ABS) composites. The TM produced from a two-stage ion-exchange process and ABS composites were compounded using melt blending. ABS/muscovite layered silicate composites were characterized using Field emission scanning electron microscope (FESEM) and transmission electron microscopy (TEM) while the thermal properties was investigated through Thermogravimetric (TGA) analysis. It was found that ABS/TM recorded higher thermal properties when compared to neat ABS and ABS/UM. The FESEM images showed better dispersion of ABS/TM compared to ABS/UM. Finally, mixed morphology of intercalated-exfoliated structure of composites was proven by TEM analysis.

Rear-end crashes are a common crash scenario, which contribute to many traffic related injuries and fatalities. A performance driving center offers adult car control classes focused on defensive driving skills, which include both classroom and behind-the-wheel instruction on a closed-road course. One focus of the class is activation of the anti-lock braking system (ABS), which was designed to help drivers during emergency braking situations. In the classroom, participants learn what ABS is as well as how and when it functions. On the closed-road course, participants learn how to activate ABS and how the system feels when it is activated. The goal of this study was to understand how knowledge of and experience with ABS prior to the class relates to a driver’s ability to activate ABS. The participants’ ability to activate ABS was evaluated by the driving instructor using a behaviorally anchored rating scale. Participants completed a survey before and after the class to gain knowledge of and experience with ABS. The results of the study showed that participants who previously knew what ABS felt like or had prior practice/training activating ABS performed significantly better activating ABS than those who simply knew what ABS means or had previously experienced ABS activation during their first of multiple attempts.

Abstract We have selected a peptide-display phage library on IgM Abs and identified a panel of phage-expressing peptides that bind to IgM Abs in general, but not to Abs of other classes. A synthetic peptide corresponding to one of the displayed peptide sequences also binds to IgM Abs. The peptides bind to both soluble pentameric Abs and to monomeric cell-surface IgM. The phage-displayed and synthetic peptides inhibit the binding of IgM Abs to Ag. These peptides may create confounding artifacts when IgM Abs are used for epitope mapping studies. Nonetheless, the peptides may have both experimental and therapeutic utility.

For achieving sufficient flame retardancy, high magnesim hydroxide (MH) content is needed in MH flame retardant Acrylonitrile-butadiene-styrene copolymer (ABS) composites (ABS/MH), which will cause a great decrease in mechanical property and difficulty in preparing samples for measurement. We prepared ABS/MH filled high 60.0% flame retardant by compounding ABS and modified flame retardant MH, fumed silica (SiO2) and zinc borate (ZB) via TX-10 phosphate/polyacrylate latex and studied the effect of a small amount of SiO2 and ZB with MH in ABS for improving the thermal decomposition of ABS/MH. The thermal stability of the modified flame retardant could meet the processing temperature of ABS. The incorporation of ZB, SiO2 or SiO2/ZB could improve the thermal stability of ABS/MH.

The purpose of this study was to investigate the optimal extraction conditions of polysaccharides fromAchyranthes bidentataBlume (ABs) and evaluate its analgesic effects. Extraction conditions of ABs were optimized by the orthogonal experiment design, and analgesic effects of ABs were assessed by the acetic acid writhing reflex test. The results show that the optimal conditions ABs: extraction temperature is 90°C, extraction time is 3.5 h. and ratio of water to raw is 40:1 ml/g. Under these conditions, the extraction yield of ABs was 5.48%. Furthermore, ABs decreased number of writhing reflex and increased writhing reflex incubation period in mice, which indicated that ABs had analgesic effects. Acute toxicity test have already proved that the ABs did not show any toxic reactions.

Abstract Acrylonitrile-butadiene-styrene copolymer (ABS) was introduced to modify the epoxy resin (EP) by the solution mixing method. The results showed that the modulus was decreased with the addition of ABS. Short carbon fibers (SCF) were chosen as the reinforcement agent to prepare high-performance EP/ABS/SCF composites. Meanwhile, a self-made conical mixer was applied to improve the dispersion behavior of the SCF in EP. The properties of both EP/ABS matrix and EP/ABS/SCF composites were investigated and discussed. The results showed that the tensile strength and impact strength of EP/ABS matrix are remarkably improved in the presence of 4,4-diaminodiphenyl methane (DDM), which reached the maximum value at 4 wt% ABS. The introduction of ABS and SCF eventually can maintain the excellent original properties of EP and greatly improve the tensile modulus of EP/ABS/SCF composites with the specialized self-made conical mixer.

Objectıve. Ankaferd hemostat (ABS; Ankaferd Blood Stopper®) contains standardized plant extracts comprising Alpinia officinarum, Glycyrrhiza glabra, Thymus vulgaris, Urtica dioica, and Vitis vinifera. ABS especially was recognized for its hemostatic effect; however, antineoplastic role of ABS was identified during the last decade. The aim of this paper is to review the molecular basis and associated clinical implications of the ABS as a topical antineoplastic agent. Materials and Methods. Up to June 2022, literature searches were performed using the internet search engines Medline, Google Scholar, and Embase: Ankaferd. PRISMA flow diagram described the Ankaferd search. Results. ABS have important effects in several cellular processes, like control of the cell cycle, apoptosis, angiogenesis, signal transduction, inflammation, immunologic, and metabolic mechanisms. The molecular basis of antineoplastic roles of ABS depends on its proteomics, metabolomics, and transcriptomics features. ABS has antineoplastic effects on solid tumors like colon, bladder, breast, and osteosarcoma cancer cells. Also, ABS effects renal tubular apoptosis and has antitumoral roles on malign melanoma cells. ABS inhibits hematological tumors like myeloma and lymphoid cells. ABS induces apoptosis in retinal cells and has inhibitory effects on mesenchymal stem cells. It has an antiproliferative role on gastrointestinal tumors like hepatocellular carcinoma cells. Moreover, ABS has a treatment supportive role in cancer since it can prevent oxidative DNA damage and decrease the intestinal damage in necrotizing enterocolitis. Furthermore, it has chemopreventive and hepatoprotective features and can be used for prophylaxis and treatment of oral mucositis. Conclusion. ABS alters cell metabolism and cell cycle. ABS has antineoplastic role on cancer cells. The expanding context of ABS compromises anti-infective, antineoplastic, and wound healing features. ABS may also be used for the palliative, adjuvant, neoadjuvant, or supportive use by interventional radiology procedures for the treatment of solid tumors. Future controlled studies are necessary to clarify the pleiotropic role of ABS like antineoplastic, antithrombotic, anti-inflammatory, anti-infective, antifungal, and antioxidative effects.

Neoplasia is a type of abnormal and excessive growth of tissue. The growth of a neoplasia is uncoordinated with that of the normal surrounding tissue, and it persists growing abnormally, even if the original trigger is removed. This abnormal growth usually forms a mass. The main objective of the present research work was the synthesis, characterization and evaluation of in vivo antitumour activity of some novel 2, 5-disubstituted 1, 3, 4-oxadiazole derivatives. The in vivo antitumour activity of synthesized compounds was evaluated by HT 29 cell line induced malignant ascites on mouse model. The apoptosis of HT 29 cells was evaluated by using Gimsa and H33342 stain and the apoptosis ratios were analysed by FCM using AnnexinV-FITC/PI staining. The present experimental data displayed that the mortality was less in all groups except in tumour control group and all the synthesized compounds AB1-AB8 (100 mg/kg) significantly increased the PILS. While 5-FU increased the life span of 97.72%, and the PILS of synthesized compounds were found to be 45.45%, 59.09%, 68.18%, 56.81%, 38.63%, 84.09%, 77.27% and 90.90%. So the Synthesized compounds AB1-AB8 at the dose of 100 mg/kg significantly improved the overall survival of all treated animals and 5-FU was not significantly differed from each other in improving the overall survival of HT-29 cells. The apoptosis ratios of synthesized compounds were found as followed: AB1=26%; AB2=37.6%; AB3=43%; AB4=29%; AB5=24.1%; AB6=59.2%; AB7=48.2%; and AB8=63% respectively, while that of the Group-II (T. control) was 6.1%. When compared with standard drug 5-FU: 66.2%, it was indicated that compound AB8>AB6>AB7>AB3 were able to significantly induce HT-29 cells apoptosis.

Eight (8) selected poultry feed samples from four (4) different brands namely; Hybrid, Chikun, Amo Byng and Vital were purchased from Makurdi Metropolis. The samples (HS, HF, CS, CF, ABS, ABF, VS and VF) denote Hybrid starter, Hybrid finisher, Chikun Starter, Chickun Finisher, Amo Byng Starter, Amo Byng Finisher, Vital Starter and Vital Finisher respectively. Toxic metals content was determined using Atomic Absorption Spectrophotometry and expressed in mg/kg. The results showed that Cd was only present in CF (0.80). Chromium was found only in ABS (15.4) and ABF (34.9). The concentration of Cu in (HS, HF, CS, CF, ABS, ABF, VS and VF) was 10.3, 15.0, 24.7, 27.9, 6.90, 9.70, 4.70 and 5.20 respectively. The concentration of Fe in (HS, HF, CS, CF, ABS, ABF, VS and VF) was 338,378, 307, 273, 389, 289, 398 and 405 respectively. The concentrations of Mn in (HS, HF, CS, CF, ABS, ABF, VS and VF) were 103, 95.3, 110, 97.4, 94.0, 103, 25.8 and 77.9 respectively. Lead was not detected in all the samples. The concentrations of Zn in (HS, HF, CS, CF, ABS, ABF, VS and VF) were 78.6, 75.1, 156, 177, 100, 67.2, 5.1 and 96.5 respectively. Copper, Fe, Mn, and Zn were the most abundant toxic metals found in the poultry feed samples. Lead was generally below the allowable limit. Chromium in ABS and ABF was higher than the permissible level. The concentrations of Fe, Mn and Zn in all the feeds were found to be above the limits. Copper found in ABS, ABF, VS and VF was within the limits permitted but levels in CS and CF were far above the limit. The concentrations of most of the trace elements were found to be higher than recommended levels which may pose some environmental and health risk if not properly regulated.
