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

<h3>Objectives:</h3> To identify genetic polymorphisms in factor I fibrinogen (rs6050) and XI plasma thromboplastin (rs4253417) Saudi women with recurrent spontaneous miscarriage (RSM). Furthermore, to compare the levels of clotting factors blood patients healthy controls. <h3>Methods:</h3> The current study was conducted at King Khalid University Hospital Riyadh, Arabia, from September 2022 June 2023. involved 100 women, 50 pregnant non-pregnant individuals, who experienced RSM. including...

Heads of sheep (n = 600) and goats 800) slaughtered at Al-Aziziah Abattoir in Riyadh, Saudi Arabia, were inspected for the presence O. ovis larvae (L). split along longitudinal axes, (L1, L2, L3) gathered. The infestation rate was significantly higher (44.5%; 356/800) than that (22.3%; 134/600). Out 151 collected from sheep, 0% L1, 1.3% 98.7% L3. total 468 goats, 1.2% 98.8% males females. Myiasis-causing authenticated as ovis, according to morphological characteristics. Polymerase chain...

Any improvements in assisted reproduction techniques at experimental level are important vitro production of large animal and human embryos. The embryo system includes three major steps, namely maturation the primary oocytes, fertilization matured culture presumptive success depends on maturation. Fenugreek seed extract (FSE) is an source steroid hormones, antioxidants, anti-inflammatories. This study aims to investigate effect FSE progression, glutathione (GSH) concentration, expression...

Light is an important environmental factor that controls the regulation of physiological functions organisms. Melatonin considered as one major hormones play role in protecting body from many harmful effects and acts a powerful anti-oxidant source to controlling levels antioxidant enzymes within body. The main objectives this work were study effect 1) photoperiod changes 2) exogenous melatonin hormone treatment on sperm properties, testis weight, embryo characteristics, concentration level...

The purpose of this study was to evaluate the effect addition Origanum vulgare extract in vitro capacitation sperm medium (IVCSM). This investigated antioxidant and antimicrobial effects O. extracts at different concentrations (0.3, 0.6, 1.2 μg/ml 25.0, 50.0, 100.0 μg/ml, respectively) IVCSM. Significant enhancements semen quality parameters such as total motility, live capacitated were found when added an source (1.2 μg/ml). treatment spermatozoa with highest concentration (100 μg/ml) for 2...

The purpose of this study was to describe the changes occurring in cytoplasmic organelles buffalo oocytes before and after in vitro maturation. total number used experiment 250 oocytes; 50 in vivo matured oocytes, 100 immature other was in vitro matured cultured TCM-199 + LH. examined showed normal ultra-structure mitochondria, smooth endoplasmic reticulum (SER), zona pellucida (ZP), lipid droplets, vesicles Golgi good type meanwhile, some differences abnormalities denuded were recorded....

Preparation of oocytes is one the critical factors that determine developmental competence embryos produced by in vitro fertilization (IVF). The present study was conducted to evaluate effect different maturation media on nuclear and cytoplasmic buffalo oocytes. Also, investigate if addition ginseng fenugreek during (IVM) would influence IVM, as well intracellular GSH level. Three experiments were achieve goals study. In first experiment, cultured without any supplementations detect most...

This study was carried out to illustrate the ultrastructure of Egyptian buffalo oocytes through in vitro maturation (IVM) period (24 h). Selected cumulus complexes (COCs) were divided into three groups relation time (8, 16 and 24 h >). After different intervals, matured examined by light transmission electron microscope (TEM). Results showed that cells close each other zona plucida (ZP) first group than second third group, lipid droplets (LD) appeared normal nearly from plasma membrane for 8...

This study was carried out to evaluate the maturation of buffalo oocytes in vitro. In first experiment, were cultured for 22 24 h in  TCM-199, CR1aa and mSOF with or without luteinizing hormone (LH). Results show that all media LH better than LH; rate low high TCM–199 LH. Moreover comparison, TCM–199+LH + LH, 1282 cultured. Maturation assessed by evaluation degree cumulus cells expansion meiotic development. indicate recovery ranged between 2.4 2.8. Moreover, results revealed rate, telophase...

The present study used Litchi chinensis 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 L. examined their anticoccidial activity rabbit hepatic coccidiosis induced by E. stiedae infection. Thirty-five rabbits were allocated into seven groups: healthy group (G1), an infected control (G2), four groups before treatment...

Abstract Eugenol was investigated for the treatment of Haemoproteus columbae (H. columbae) infected squabs (young domestic pigeons, Columba domestica). Thirty naturally-infected were divided into three groups 10 each. One group treated with Eugenol, while positive and negative control administered buparvaquone (Butalex®) distilled water, respectively. The number red blood cells (RBCs) calculated in all before after at 4-day intervals 16 days. results showed a significant therapeutic effect...
