Uterotubal junction of the bovine (Bos taurus) versus the dromedary camel (Camelus dromedarius): Histology and histomorphometry.

This study aims to conduct a comparative analysis of the uterotubal junction in two distinct mammalian species, the bovine (Bos taurus) and the dromedary camel (Camelus dromedarius), focusing on histological and histomorphometric parameters. Uterotubal junction (UTJ) was dissected from 8 cows and 12 camels with dominant follicles, and processed for H&E staining for histology, and histomorphometry examination. The results showed that the camel uterotubal junction papillae (UTJP) existed only in camels and was completely absent in cattle.

The protective effects of some herbs on mitigating HFD-induced obesity via enhancing biochemical indicators and fertility in female rats.

The potential of plant-based diets and drugs to prevent and control obesity has been attributed to the presence of several biologically active phytochemicals. The study aimed to assess herb consumption's impact on alleviating the risks and hazards associated with obesity induced by a high-fat diet (HFD) and the promotion of fertility. Eighty rats were allocated into four distinct groups.

Economics of treatment with GnRH agonist 7-14 days after artificial insemination in repeat breeder lactating dairy cows.

This study looked at the effectiveness and financial benefits of treating repeat breeder (RB) dairy cows with the GnRH agonist gonadorelin 7-14 days after artificial insemination (AI). A total of 188 healthy dairy cows (2.4 ± 1.

Lyophilized equine platelet-rich plasma (L-GF) antagonize the Reproductive toxicity and oxidative stress Induced by Cyclophosphamide in female rats.

Background: The antineoplastic agent Cyclophosphamide (CP) induces reproductive toxicity. New strategies for protecting ovarian tissue damage in women with chemotherapy-induced reproductive toxicity are essential. This study was designed to evaluate the possible protective effect of combined treatment with L-GF on CP-induced reproductive toxicity in the mature female rat.

Intraovarian Injection of Reconstituted Lyophilized Growth-Promoting Factor Extracted from Horse Blood Platelets (L-GF) Increases Oocytes Recovery and In Vitro Embryo Production in Holstein Cows.

The purpose of this study was to determine the impact of intraovarian injections of a reconstituted lyophilized growth-promoting factor extracted from horse blood platelets (L-GFequina) on the number of ovarian follicles, the recovery of cumulus−oocyte complexes (COCs), and embryo development to the blastocyst stage in Holstein cows. Thus, 12 Holstein cows were assigned to three protocols. According to the number of punctured follicles in protocol 1, ovum pick-up (OPU) was conducted on days 6 and 14 of the cycle (day 0 = estrus).

Platelet-rich plasma in animal reproductive medicine: Prospective and applications.

Platelet-rich plasma (PRP) is the fraction of the plasma enriched with a platelet level above baseline, and it plays an essential role in tissue regeneration. The attention to PRP as unconventional therapy has increased during the past two decades. In animals, applications of PRP showed various degrees of success in a wide range of medical applications, from musculoskeletal injuries to ovarian insufficiency.

Age-related changes in testicular morphometry and function in Egyptian donkeys.

This study aimed to assess the effects of age on testicular morphometry and function in donkeys. Testes and epididymides of 57 donkeys were harvested immediately after slaughtering. The donkeys were grouped: young (1-4 years old, n = 13); adult (5-15 years old, n = 25) and aged (>15 years old, n = 19).

Effect of gold nanoparticles shape and dose on immunological, hematological, inflammatory, and antioxidants parameters in male rabbit.

Background And Aim: Gold nanorods (AuNRs) have gained much attention recent years due to their promising optical and chemical properties and are hence used in applied research and industrial nanotechnology. This study was designed to investigate the effect of gold nanoparticle shape (Gold nanorods vs. gold nanosphere) on immune response in rabbit.

Effect of body condition score on the testicular biometrical measures, semen characteristics and testosterone level in jackass.

This study was undertaken to evaluate the effect of body condition score (BCS) on testicle and epididymis biometrics, semen characteristics and testosterone level in Egyptian Jack. This study was conducted on 50 mature Jacks divided according to their body condition score into four groups: Poor (G1), moderate (G2), good (G3) and fat (G4). The complete testis was collected immediately after execution in the Giza Zoo abattoir; then, the epididymis was carefully dissected at the testicular junction.

Effect of oxygen tension and antioxidants on the developmental competence of buffalo oocytes cultured .

Aim: Oxidative stress (OS) is one of the major disruptors of oocyte developmental competence, which appears due to the imbalance between the production and neutralization of reactive oxygen species (ROS).

Materials And Methods: In Experiment 1, buffalo oocytes were matured, fertilized, and cultured at 38.5°C under 5% CO + 20% O in standard CO incubator (OS) or under 5% O + 5% CO + 90% N (Multi-gas incubator, low O).

Effect of acute gold nanorods on reproductive function in male albino rats: histological, morphometric, hormonal, and redox balance parameters.

In this study, we investigated the effect of acute administration of gold nanorods (AuNRs) on testicular function, sexual hormones, and oxidative stress parameters in male albino rats. Forty mature male albino rats were divided into two equal groups (n = 20/each). The first group received 1 ml saline solution intraperitoneally (i.

Influence of follicle size, methods of retrieval on oocytes yield and morphology in Egyptian Jennies ovaries with special reference to maturation rate in vitro.

Unlabelled: This work was designed to evaluate the ovarian follicular development, oocytes morphology, methods of oocytes reterival, and the effect of different in vitro maturation (IVM) media on cumulus cell expansion and nuclear maturation of Jennies oocytes. Experiment 1, the number of small (<6 mm), medium (6 to 9 mm) and large size (>10 mm) ovarian follicles was recorded. Cumulus-oocyte-complexes (COCs) were reterived and classified into 4 Grades based on their cumulus-cells investment and the homogenous of the ooplasm.

Mitochondrial distribution, ATP-GSH contents, calcium [Ca2+] oscillation during in vitro maturation of dromedary camel oocytes.

Dromedary camel oocytes have the ability to spontaneous parthenogenetic activation and development in vivo and in vitro. The present study was conducted to investigate changes in mitochondrial distribution, adenosine triphosphate (ATP), and glutathione (GSH) contents and [Ca(2+)] oscillation during in vitro maturation and spontaneous parthenogentic activation of dromedary camel oocytes. Dromedary camel cumulus-oocyte complexes (COCs) were matured in TCM199 medium supplemented with 10% FCS + 10 μg/mL FSH + 10 IU hCG + 10 IU eCG + 10 ng/mL EGF and 50 μg/mL gentamycine.
