DNA damage and hematological changes in Common carp (Cyprinus carpio) exposed to oxadiazon

This study was carried out to investigate the genotoxic, and hematological and serum biochemical effects of a widely used herbicide, oxadiazon in common carp ( Cyprinus carpio ) fingerling. Fish were exposed to different concentrations (0, 1, 1.5 and 2 ppm) of the herbicide for 30 days. Blood samples were collected, then comet assay in circulating erythrocyte cells was applied. Erythrocytes cells of fish exposed to 1, 1.5 and 2 ppm of oxadiazon showed DNA damage (21.3%, 22.9%, and 28.4%, respectively) significantly higher than the control group. Moreover, exposure to oxadiazon significantly decreased WBC, RBC, Hb, Hct as well as serum albumin, glucose, and total protein levels, while serum ALP was significantly increased in the exposed fish groups. No significant differences were found in MCV, MCHC and MCH levels between oxadiazon treatments and control groups. In conclusion, this study shows that oxadiazon is highly toxic to C. carpio and causes significant changes in hematological and biochemical parameters as well as indicates the mutagenic potential of oxadiazon in the erythrocyte cells of this fish.
Development and Application of Stable Isotope Dilution Assays for the Fusarium Mycotoxins Enniatins and Beauvericin

A stable isotope dilution assay (SIDA) for the determination of the Fusarium mycotoxins enniatins (ENNs) A, A1, B, B1 and beauvericin (BEA) was developed. Sixty-five cereals and related food samples from Germany, and 60 Chinese medicinal herb samples were analyzed by SIDA for contamination of ENNs and BEA. The fate of ENNs and BEA during beer making was followed by SIDA, showing low carry over of these mycotoxins from barley to beer. The effect of sourdough processing and baking on ENNs and BEA was studied by SIDA, which revealed that they were reduced partly from the starting materials.
The Association of the Single-and Twin-Bearing with the Lipid Profile on the Status of the Reproductive Hormones in Iraqi Awassi Ewes

| The lipid profile assay is considered as good indicators of the physiological state and reproductive performance of livestock. Therefore, this study aimed to evaluate the association of progeny type with the lipid profile on the status of the reproductive hormones in Iraqi Awassi ewes. A total of 200 sexually mature ewes (114 ewes with single progeny and 86 ewes with twin progeny), non-pregnant and non-lactation, aged between 2.5 to 5 years were included in this study. The blood samples were collected and the sera were separated from blood to determine lipid profile assay and reproductive hormones. The result referred to the significant differences (P < 0.05) in cholesterol and sex hormones levels between ewes with single compared to the twin progenies. The strongly positive correlation (P < 0.01) was recorded between ewes with twin progeny with cholesterol (r=0.52, P=0.01), high-density lipoprotein (HDL) (r=0.31, P=0.04), estradiol (r=0.46, P=0.02), and progesterone (r=0.50, P=0.03) respectively. In conclusion, birth progeny type is associated with lipid profile and sex hormones levels in Awassi ewes. The ewes with twin lambs are associated with the highest cholesterol and sex hormones levels than ewes with a single lamb.

The system was trained and evaluated on the realistic dataset that we collected from the surveillance camera
Parameter Optimization of Double LCC MCRWPT System Based on ZVS

At present, magnetically coupled resonance wireless power transfer (MCRWPT) is the main technology used in electric vehicle wireless power transfer (WPT) due to its advantages of high transmission power and high efficiency. The resonant compensation circuit of the system generally adopts the double LCC (DLCC) structure, which has many capacitor and inductor components. Therefore, it is necessary to optimize the circuit parameters to improve the transmission performance of the system. In this study, the DLCC compensation circuit was modeled and analyzed to lay the foundation for parameter optimization. Secondly, the size parameters of the energy transmitting and receiving coil were determined, and the influence of the change of the primary and secondary compensation inductance on the circuit element stress and output performance was analyzed to determine the optimal compensation inductance value. Thirdly, the realization condition of zero voltage switching (ZVS) was analyzed, the relationship between the input impedance angle of the compensation circuit and the component parameter value was obtained, and a parameter optimization control strategy for realizing ZVS was proposed. Finally, through simulation and experiment, it was concluded that under different power levels, the efficiency of the parameter optimization strategy proposed in this study is as high as 91.86%, increasing by about 1%. Therefore, the research undertaken in this study can promote the development of WPT technology and has certain practical significance.
The Development of Yolk–Shell‐Structured Pd&ZnO@Carbon Submicroreactors with High Selectivity and Stability

Design of multicomponent yolk–shell structures is crucial for the fabrication of micro/nanoreactors for a variety of applications. This work reports the rational design and synthesis of yolk–shell‐structured submicroreactors with loaded metal nanoparticles into ZnO–microporous carbon core–shell structures. The solvothermal treatment and carbonization process of uniform zeolitic imidazolate framework‐8 (ZIF‐8)@resin polymer core–shell structures leads to the generation of yolk–shell‐structured ZnO@carbon. The synthesis conditions are optimized to track the evolution of ZIF‐8 in a confined space of resin polymer as a submicroreactor itself. It is found that nanoribbon evolution occurs via the formation of the intermediate needle‐like particles. The Pd&ZnO@carbon submicroreactor is shown to be a highly selective catalyst (selectivity >99%) for hydrogenation of phenylacetylene to phenylethylene. The excellent performance of Pd&ZnO@carbon particles is evidenced by higher conversion and selectivity than that of Pd/ZnO and Pd/C with similar Pd loading. Furthermore, Pd&ZnO@carbon submicroreactors show superior catalytic stability, and no deactivation after 25 h of reaction. The proposed strategy is promising for the design of multifunctional micro/nanoreactors or nanocontainers for construction of artificial cells.

Establishing the Pupils’ Level of English Vocabulary Proficiency in Public and Private Rural Primary Schools in Kyuso Division of Kitui County

The purpose of this study was to answer the question of what is the pupils' level of English vocabulary proficiency in public and private rural primary schools in Kyuso Division in Kitui County. The study was an attempt to provide relevant data on English vocabulary proficiency in Kyuso area. This study focused on the English vocabulary proficiency in Kyuso area among children in classes’ two to four. Learners from one class to the next depicted some changes hence a level of vocabulary proficiency manifestation. The study was limited to respondents within the sample in rural areas where the language of communication after school was purely Kikamba. The two categories of primary schools in the area were day schools, unlike secondary schools whereby 90% of them are boarding. The assumption was that the pupils had the same school hours, share the same locality and the same parents. The question was why there was a big difference in children from the two categories of schools. The study was based on primary schools, the level where the grammatical rules are initiated, and as the children grow up, they continue to utilize what they continue acquiring. It was observed that competent speakers show up right from primary schools. It is also at the primary level where a child can be ‘modelled' to improve or change to a better person due to their language acquisition device (LAD). In both public and private primary schools there seem to be differences in pupils level of vocabulary proficiency.
Investigating the Roles of Follicular Dendritic Cells and Activation-induced Deaminase in Germinal Centers

During a T-dependent immune response, activated B cells enter structures called germinal centers (GC) in the follicles of secondary lymphoid organs. GC B cells proliferate and undergo diversification of their Ig through somatic hypermutation and class-switch recombination. These Ig diversifications require the activity of the enzyme activation-induced deaminase (AID). Clonal selection within GCs selects GC B cells with the highest affinities for antigen to mature into plasma cells and memory B cells. GCs are underpinned by stromal cells called follicular dendritic cells (FDC). FDC functions include secretion of B cell chemokines and the retention of Ag complexes that allow GC B cells to test the affinity of their Ig. FDCs require constitutive signaling through lymphotoxin beta receptor (LTβR) from lymphotoxin alpha-beta (LTαβ) on the surface of B cells to maintain their functions. In these studies, I investigated the properties of GCs using two primary experimental models. First, I employed genetic and pharmacological ablation of LTβR signaling to investigate the expression of AID and the function of GCs in the absence of FDCs. I determined that FDCs are not required for GC formation or the expression of AID in lymph nodes, but that FDCs are crucial for affinity maturation. Second, I examined the competition between AID-/- and WT B cells in the GCs of mixed BM chimeras to investigate the role of affinity maturation during clonal selection. I found that AID increases GC B cell apoptosis, likely by inducing DNA damage, and that this is important in regulating GC size. I also found that AID-/- B cells accumulate at the centrocyte stage of the GC reaction and that this is due to a partial block in plasma cell maturation. %%%%PhD
Efecto de luz ultravioleta-C y ultrafiltración sobre las características fisicoquímicas, antioxidantes y sensoriales de savia de Agave salmiana almacenada

The primary objective of this research study is to analyze the physicochemical, antioxidant (total phenolic compounds and antioxidant capacity), microbial (aerobic mesophilic bacteria and molds-yeasts), and sensory (acceptability) characteristics of stored Agave salmiana sap. The sap is: a) treated with ultraviolet-C light, b) ultrafiltrated, and c) ultrafiltrated and treated with ultraviolet-C light (five minutes). The ultrafiltrated (UF) and ultrafiltrated/ultraviolet-C (UF/UV) saps are stored at 4°C (UF4 and UF/UV4) and 25°C (UF/UV25) for 28 days. The results show that ultraviolet-C light has no significant effect on pH, total soluble solids, and acidity. But, a decrease in logarithmic cycles of aerobic mesophilic bacteria (AMB) and molds-yeasts (MY) is observed after ultraviolet-C light treatment (30 min). There is a significant decrease in total phenolic compounds at the end of storage. It is concluded that the UF4 and UF/UV4 agave saps (five min treatment; 28 days storage) are the recommended treatments for storage since they retain physicochemical, antioxidant, and sensory characteristics while preventing AMB and MY growth.
Fourier transform infrared spectroscopy (FTIR) application chemical characterization of enamel, dentin and bone

ABSTRACT Fourier transform infrared spectroscopy (FTIR) has been used extensively for chemical characterization of mineralized tissues in the past few decades. FTIR is an ideal technique to analyze chemical structural properties of natural materials, since the frequencies of several vibrational modes of organic and inorganic molecules are active in the infrared. This review discusses the use of FTIR methodology, highlighting the attenuated total reflection (ATR) sampling mode, particularly for characterization of enamel, dentin and bone tissues. Enamel, dentin and bone, are composed of an organic and a mineral phase. The mineral phase is characterized essentially as nonstoichiometric substituted apatite, being the carbonate and phosphate spectral peaks the main representative of these phase. Organic matrix of the post-eruptive enamel is small (∼1% weight (wt)). The dentin and bone organic phases are mainly composed of type I collagen that appears as spectral bands of amide I, amide II, amide III bands. Furthermore, synthetic apatite materials are being designed for total or partial replacement, restoration or augmentation of these biological tissues with FTIR assistance.

Création d'enzymes multimodulaires à façon dédiées à la dégradation de substrats complexes

Pour reduire notre empreinte carbone sur l’environnement, il est urgent de developper des procedes industriels utilisant une source de carbone renouvelable comme la biomasse lignocellulosique. La paroi cellulaire vegetale est un enchevetrement complexe de cellulose, d’hemicelluloses et de lignines. Elle resiste aux attaques biologiques et chimiques mais limite le developpement d’une bioeconomie responsable. Dans la Nature, des enzymes multimodulaires produites par certains microorganismes peuvent la deconstruire. Toutefois, ces enzymes sont majoritairement etudiees sur des substrats artificiels ou purifies. Dans cette these, nous proposons de les etudier sur des substrats broyes puis des coupes de paille de ble brutes. Les enzymes multimodulaires sont preparees a facon en utilisant la propriete d’association covalente des proteines Jo et In. Nous avons ainsi associe la xylanase NpXyn11A de N. patriciarum avec deux modules non catalytiques : le CBM3a de C. thermocellum ou le CBM2b1 C. fimi ciblant la cellulose ou les xylanes respectivement. Les proprietes biochimiques de ces proteines chimeriques ont ete comparees aux modules sauvages. L’activite enzymatique des proteines chimeriques a ensuite ete etudiee sur des substrats solubles, jusqu’a des substrats insolubles comme le son et la paille de ble, notamment par immunocytochimie. Ce travail a mis en evidence l’importance de la relation enzymes/substrats pour une caracterisation in muro d’activite enzymatique et une meilleure comprehension de la deconstruction de la biomasse vegetale.

Enfin l’influence du stockage a l’air de Li2MnSiO4/C est mise en evidence et un mecanisme concernant la formation de Li2CO3 est propose.En seconde partie, une synthese de LiMnSiO4/C en plusieurs etapes est proposee a partir de l’olivine MgMnSiO4/C, suivie d’une oxydation chimique et d’une lithiation electrochimique. Chaque etape est caracterisee pour determiner la structure, l’etat d’oxydation et le comportement electrochimique du materiau obtenu.Pour conclure cette etude, les deux materiaux optimises ont ete testes suivant les profils d’applications spatiales (satellites LEO et GEO). La meilleure cyclablite de LiMnSiO4/C est confirmee ainsi que sa legitimite en tant qu’alternative prometteuse au materiau conventionnel Li2MnSiO4/C.
EVALUATION OF FORMOL GEL SLIDE TEST WITH REFERENCE TO BLOOD MICROSCOPY AND ENZYME LINKED IMMUNOSORBANT ASSAY FOR DIAGNOSIS OF SURRA IN CATTLE

The objective of the present study was to evaluate the conventional Formol Gel Slide Test (FGST) vis-avis Enzyme Linked Immunosorbant Assay (ELISA) in diagnosis of Trypanosoma evansi infection in cattle. In all, 51 adult Holstein-Friesian cattle were categorised in three groups i.e T. evansi positive symptomatic, parasite negative symptomatic and apparently healthy from 12 animal sheds at Guwahati, Assam. The FGST was performed with some modifications and results obtained were compared with blood smear findings and ELISA. The serum samples obtained from symptomatic cattle with or without detectable parasite in blood were found positive in the FGST as evidenced by immediate gellification and opacity development akin to white of a boiled egg. When compared to ELISA, the sera from clinical cases with high antibody titre (OD value >0.736) were found positive in FGST, while those from asymptomatic cattle with lower antibody titre, (OD value < 0.736) were all negative in the test. Thus the detection performance of blood microscopy, FGST and ELISA were found to be 3.92%, 5.88% and 17.64 % respectively. The study also suggests that ELISA as usual is more sensitive and suitable for screening of cattle herds during epidemiological investigation. However, the study revealed FGST to be a suitable, simple to perform and low cost screening test for field diagnosis of surra in clinically suspected cattle. * Corresponding author KEYWORDS

Microengineered Bioartificial Liver Chip for Drug Toxicity Screening

Microfluidic 3D cell culture is a promising technology for the screening of drug toxicity profiles. In this study, a bioartificial liver consisting of a surface‐engineered microfluidic silicon chip with microtrenches mimicking hepatic sinusoids is shown to extend 3D primary hepatocyte culture and improve in vitro drug screening for hepatotoxicity, with respect to the state‐of‐the‐art literature on this subject. Primary hepatocytes hosted in the 3D heparin‐coated microtrenches (the bioartificial liver) secrete high levels of albumin and urea over 4 weeks. The cytotoxicity of common drugs, namely, acetaminophen, chlorpromazine, and tacrine, was assessed on primary hepatocytes both at day 1 and day 7. The results suggest that mimicking hepatic sinusoids using a microtrench format allows the maintenance of difficult‐to‐culture primary hepatocytes to be extended to 4 weeks and provides an alternative model to animal studies for the screening of the cytotoxicity of new drugs.
An Information Processing Theory of Verbal Learning

A theory of some elementary forms of human symbolic learnning: memorization, discrimination, association, and attention direction. The theory is concerned with mental activity at the level of the processing of information symbols, which are the basic units manipulated. The precise statement of the theory is given in th language of a digital computer, specifically as a set of programs in IPL-V (Information Processing Language), called EPAM (Elementary Perceiver and Memorizer). The paper deals generally with information structures and processes for discrimination and association learning, and specifically with behavior in the standard rote-learning task. A number of implications of the theory in rote-learning situations are explored, and comparisons are drawn between the behavior of human subjects in these situations and the behavior of the EPAM model.
The Use of Live Cell Imaging and Automated Image Analysis to Assist With Determining Optimal Parameters for Angiogenic Assay in vitro

Testing angiogenic potential and function of cells in culture is important for the understanding of the mechanisms that can modulate angiogenesis, especially when discovering novel anti- or pro-angiogenic therapeutics. Commonly used angiogenic assays include tube formation, proliferation, migration, and wound healing, and although well-characterized, it is important that methodology is standardized and reproducible. Human endothelial progenitor cells (EPCs) are critical for post-natal vascular homeostasis and can be isolated from human peripheral blood. Endothelial colony forming cells (ECFCs) are a subset of EPCs and are of interest as a possible therapeutic target for hypoxic diseases such as kidney disease, as they have a high angiogenic potential. However, once ECFCs are identified in culture, the exact timing of passaging has not been well-described and the optimal conditions to perform angiogenic assays such as seeding density, growth media (GM) concentrations and end-points of these assays is widely varied in the literature. Here, we describe the process of isolating, culturing and passaging ECFCs from patients with end-stage renal disease (ESRD), aided by image analysis. We further describe optimal conditions, for human bladder endothelial cells (hBECs), challenged in angiogenic assays and confirm that cell density is a limiting factor in accurately detecting angiogenic parameters. Furthermore, we show that GM along is enough to alter the angiogenic potential of cells, seeded at the same density. Lastly, we report on the success of human ECFCs in angiogenic assays and describe the benefits of live-cell imaging combined with time-lapse microscopy for this type of investigation.
