Sections from duodenum, jejunum and ileum of local breeds of goat (Capra hircus) were studied histologically using light and scanning electron microscopy. The wall of goat small intestine is composed of typical layers: lamina epithelialis mucosae, lamina propria, lamina muscularis mucosae, tunica submucosa, tunica muscularis and tunica serosa. Small intestine villi were covered by a simple columnar epithelium with... Read more.

The conventional dilaceration of ovaries is binding at the beginning of ovary development. However, reading ovarian tracheoles was very easy in stage I-II mean. The combination of both methods can really reduce the number of age indeterminations recorded with the two methods separately. The present study aimed to identify a method capable of determining physiological age of mosquitoes regardless of their ovarian... Read more.

The present study was carried out to determine the effects of aflatoxinB1 (AFB1) on the skeletal system of the fetuses of balady rabbits. The female animals were divided into three groups, one control and two treated, the control group contained four dams, the intoxicated group with 0.1 mg/kg contained six dams while the intoxicated with 0.05 mg/kg contained three dams. A dose of 0.1 and 0.05 mg/kg/day AFB1 was... Read more.

CD44 family belongs to a large group of proteins that bind to hyaluronic acid. It has important role in oocyte maturation, fertilization and embryo development. We analyzed CD44 in oocytes and embryos of goat and different breeds of sheep. We used both Kermani and baluchi breeds of sheep, two Rayeni and Tali goats. Domestic animals kept after feeding for 3 months exude embryos and oocyte. After this, the animals were... Read more.

Cleft palate (CP) is a common congenital defect. It causes serious problem to cleft-affected children. The gold standard of care is autogenous bone grafting which may cause additional problems together with long and extensive medical interventions. Tissue engineering is a promising solution for a widespread range of defects and disorders. It is reasonable to utilize this novel technology for CP management. Stem cells... Read more.

Tadpoles of stage 49 and 41, respectively were examined and analyzed using scanning electron microscope. In Rana tadpoles, the mouth was ventral and the oral disk opening had the same vertical and horizontal opening size. While in Bufo tadpoles, the mouth was anterio-ventral and the oral disc had its horizontal... Read more.

An organelle is a specialized functional subunit within cells carrying out specific functions. These compartments which may or may not be enclosed in a lipid bilayer are found in microorganisms. While those found in eukaryotic cells are usually enclosed in lipid bilayer, those in prokaryotes don’t. All microbes have compartments common to them like the nucleic acids, protein, ribosomes as well as unique... Read more.

Having obtained observations of gene expression profiles from the literature, we estimated autoregressive models of mouse preimplantation development and observed interaction among stages. Gene expression profile at the earliest stage is not generally significant, but for observations where profiles at 8-cell embryo and morula stages are relatively great, the effect of unfertilized egg is significantly positive. Key... Read more.

Modern dairy cattle breeding strategies depend on linkage analysis and quantitative trait loci (QTL) of genes involved in milk yield and composition. This is because of their biological desired quantitative traits that play key roles in milk production. In this study, three genes directly related to milk production: prolactin (PRL), bovine kappa-casein (K-CN) and the pituitary-speciﬁc transcription factor (PIT-1) were... Read more.

An attempt was made to apply hazard analysis critical control points (HACCP) system in dairy farms in Khartoum State and to suggest control limits for them based on the international standard. World Health Organization (WHO) and Food and Agriculture Organization (FAO) recommended the HACCP system as a modern tool for prevention. Critical points associated with animal health were investigated using screening tests such... Read more.

Anopheles gambiae, which is the main malaria vector in Benin has developed high level of resistance to pyrethroid insecticides. This raises serious concerns to the future use of long- lasting insecticidal nets (LLIN) and indoor residual spraying (IRS). It is therefore important to seek better and effective resistance management strategies which will use organophosphates or carbamates as alternatives against pyrethroid... Read more.
