Protective Effect of Peel Extract-Prepared Nanoparticles on Rabbits Experimentally Infected with .

The present study used peel extract to synthesize silver nanoparticles (AgNPs). This technique is eco-friendly and can be performed in a single step; thus, it has attracted great attention for NPs biosynthesis. Herein, we biosynthesized AgNPs with peel extract and examined their anticoccidial activity in rabbit hepatic coccidiosis induced by infection.

Microbiological investigation study for Apis mellifera yemenitica and Apis mellifera carnica bee venoms on selected bacterial strains.

Bees are one of the ancient and the most social insects worldwide. They are of great economic and medical importance. Bee venom (BV) has many therapeutic effects and has been used since ancient times for the treatment of many diseases.

Prevalence Rate and Molecular Characteristics of L. (Diptera, Oestridae) in Sheep and Goats from Riyadh, Saudi Arabia.

Heads of sheep ( = 600) and goats ( = 800) slaughtered at Al-Aziziah Abattoir in Riyadh, Saudi Arabia, were inspected for the presence of larvae (L). Heads were split along the longitudinal axes, and larvae (L1, L2, and L3) were gathered. The infestation rate was significantly higher in goats (44.

Study the Effect of Microinjection of Zn, Fe, and Cu Loaded in Montmorillonite on Development Activities in Fertilized Chicken Eggs.

This study aims to reduce embryonic mortality, increase body weight, and improve immune system in chicken. A total of 240 eggs were assigned to three treatments (n = 60) and injected with cooper (Cu), zinc (Zn), and iron (Fe) loaded by montmorillonite (Mnt), and one untreated group (n = 60). Some hormones and enzymes related with growth were measured in terms of serum, and expression of some genes related to growth, immune, and programmed cell deaths that were determined in the liver and spleen of chicken by RT-qPCR.

Use of black seed (Nigella sativa) honey bee to improve sheep oocyte maturation medium.

Sheep are important livestock and a source of milk, meat, and wool globally. The increasing demand for animal protein requires increased productivity in sheep. In vitro fertilization and maturation can improve sheep productivity.

The role of honeybee pollen as a natural source of antioxidants in the in vitro maturation medium of sheep oocytes and its effect on gene expression.

This study aimed to investigate the effect of honeybee pollen as an antioxidant source in a maturation medium of sheep oocytes on the in vitro maturation rate, glutathione concentration, and gene expression. To our knowledge, this study might be the first of its kind in this field. Sheep oocytes were cultured in vitro with honeybee pollen at four different concentrations (0.

Effects of Eugenol on in domestic pigeons () from Riyadh, Saudi Arabia.

Eugenol was investigated for the treatment of () infected squabs (young domestic pigeons, ). Thirty naturally-infected squabs were divided into three groups of 10 each. One group was treated with Eugenol, while the positive and negative control groups were administered buparvaquone (Butalex®) and distilled water, respectively.

Immunotoxicity evaluation of novel bioactive composites in male mice as promising orthopaedic implants.

Objective: In orthopaedics, novel bioactive composites are largely needed to improve the synthetic achievement of the implants. In this work, semiconducting metal oxides such as SiO, TiO, and ZrO particles (Ps) were used individually and in different ratios to obtain different biphasic composites. The immunotoxicity of these composites was tested to inspect the potential toxicity prior to their use in further medical applications.

Effect of various concentrations of caffeine, pentoxifylline, and kallikrein on hyperactivation of frozen bovine semen.

Caffeine, pentoxifylline, and kallikrein are substances that affect the efficiency of sperms in the fertilization process; however, they have not been adequately studied. The present study aimed to examine the influence of caffeine, kallikrein, and pentoxifylline on sperm motility in bovine as well as investigate their optimum concentrations for increasing the movement of sperms in bovine. Frozen bovine sperms were thawed in universal IVF medium supplemented with 1, 5, and 10 mM caffeine or pentoxifylline or 1, 4, and 8 U/mL kallikrein and were then incubated for 30 min.
