Antioxidants have valuable effects on the process of spermatogenesis, particularly with diabetes mellitus (DM). Therefore, present study investigated impact and intracellular mechanisms by which thymoquinone (TQ) works against diabetes-induced testicular deteriorations in rats. Wistar male rats (n = 60) were randomly allocated into four groups; Control, Diabetic (streptozotocin (STZ)-treated where was induced intraperitoneal injection STZ, 65 mg/kg), + TQ (diabetic treated (50 mg/kg) orally...
The present study looks for components in seminal plasma (SP) and/or serum that are closely related to vivo fertility of buffalo bulls. Fourteen healthy mature bulls were classified according their into fertile ( n = 10) and subfertile 4) groups. Semen samples collected from all animals 12 replicates. ejaculates examined sperm characteristics before being centrifuged collect SP hormonal (FSH, LH, testosterone, IGF-1), biochemical [total antioxidant capacity (TAC), catalase (CAT), glutathione...
This study was conducted to explore the effects of dietary inclusion Chlorella vulgaris (CV) or/and vitamin C (VC) on growth, hemato-biochemical parameters, oxidative and antioxidant status, reproductive hormones, semen quality variables, scrotal-testicular dimensions Zaraibi goat bucks. Twenty sexually mature bucks (41.49 ± 0.91 kg BW) were randomly divided into 4 groups (5 bucks/group). The control group fed diet, while other three received a diet supplemented with VC (2 g/animal /day), CV...
Cytochrome P450 aromatase (encoded by the CYP19A1 gene) regulates oestrogen biosynthesis and so plays an essential role in female fertility. We investigated genetic association of with risk anoestrus Egyptian water buffaloes. A total 651 animals (326 anoestrous 325 cycling) were used this case-control study. Using single-strand conformation polymorphisms sequencing, four single nucleotide (SNPs) detected; c.-135T>C SNP 5'UTR three non-synonymous SNPs: c.559G>A (p. V187M) Exon 5, c.1285C>T...
Although various progestagens are often used to induce and synchronize estrus ovulation in small ruminants, concerns regarding residues the impetus develop alternative approaches, including reduced doses of progestagens.Therefore, this study investigated effects synchronization protocols on fertility Rahmani ewes during non-breeding season.In June, 82 were randomly assigned five groups each group received 1 5 treatments: (1) The (n = 10) intramuscularly (IM) injected with 20 mg progesterone...
Activators of both adenosine 5'-triphosphate (ATP)-sensitive K(+) (KATP) channel and cystic fibrosis transmembrane conductance regulator (CFTR) Cl(-) have significant in vivo vitro neuroprotection against glutamate-induced death some neuronal cells. Here, the effect KATP activator, pinacidil, CFTR opener, levamisole, oxidative stress were investigated mouse hippocampal cells, HT22. The results from cell viability assay (WST-1) showed that pinacidil levamisole weakly protected cells toxicity...
This study aimed to improve the staining of frozen-thawed Japanese Black bull sperm acrosomes with fluorescein isothiocyanate-conjugated peanut agglutinin (FITC-PNA). Spermatozoa were washed, fixed 1-3% paraformaldehyde (PFA) in suspension for 10, 20, and 30 min, permeabilized 0-2% Triton X-100 5 stained FITC-PNA, mounted different antifade agents (0.22 M 1,4-diazabicyclo [2,2,2] octane (DABCO), SlowFade®, ProLong®) (In-suspension) or on a smear (On-smear). The spermatozoa categorized into...
Lead is a highly prevalent heavy metal pollutant in human and animals which has various toxicological effects on the different organs including reproductive system particular aspect male testis. (Pb) exposure enhances generation of Reactive Oxygen Species (ROS) negatively affect testis structure functions. The present study aimed to investigate effect garlic supplement daily basis its prophylactic possibility against lead acetate induced testicular dysfunction. Thirty two adult rats were...
Background: Sodium nitrite (NaNO2) is a chemical substance used to enhance taste, add color, and keep food products fit for consumption longer time. NaNO2 gives rise negative adverse effect on male reproductive function. Odontonema cuspidatum (OC) natural plant that possesses antioxidant capacity. Aim: Our research evaluates the potential beneficial of extract harmful effects caused by testicular tissue sperm characteristics rats. Methods: Four groups with total forty rats: control,...
Recent studies showed the modulatory effect of kisspeptin (KP) on calcium waves through cell membrane and inside cell. Spermatozoon can induce similar ooplasmic oscillations at fertilization to trigger meiosis II. Here, we evaluated KP supplementation with 6-dimethylaminopurine (6-DMAP) for 4 h embryonic development after oocyte activation single electric pulse, 5 µ M ionomycin, or 8% ethanol. Compared control nonsupplemented groups, significantly improved embryo developmental competence...
This study was undertaken to investigate the development of immature oocytes after their fusion with male somatic cells expressing red fluorescence protein ( RFP ). ‐expressing were fused oocytes, matured in vitro and then parthenogenetically activated. Somatic nuclei showed spindle formation, 1st polar body extrusion maturation protruded 2nd parthenogenetic activation. expressed resultant embryos; two‐cell stage blastocysts. Chromosomal analysis aneuploidy 81.82% resulting blastocysts while...
This study investigates the consequence of adding platelet-rich plasma (PRP) on post-thawed quality and in vitro fertility buffalo bull semen. Fifty-four ejaculates from nine bulls were collected, every ejaculate was then dispensed into 5 equal parts, diluted with Optixcell extender supplemented five [0, 5, 10, 15, 20] proportions PRP followed by freezing using usual protocol. Post-thaw sperm motility, viability, integrity (%) membrane, acrosome, DNA, mitochondrial membrane potential...
