Background: It is desirable in estrus synchronization in sheep to avoid intravaginal devices and to shorten the program from 14 to 6 days. Moreover, replacement of eCG with safe, cheap, and efficient gonadotropin is in worldwide demand.

Aims: This study investigates the possibility of replacing eCG with human recombinant FSH (hrFSH) and CIDR with progesterone injections for estrous synchronization in ewes.

Background: Repeated Ovum Pick Up (OPU) could have a detrimental effect on ovarian function, reducing Embryo Production (IVEP). The present study examined the therapeutic effect of adipose-derived Mesenchymal Stem Cells (MSCs) or its Conditioned Medium (ConM) on ovarian trauma following repeated OPU. Resolvin E1 (RvE1) and Interleukin-12 (IL-12) were investigated as biomarkers.

Artificial insemination in camels remains undeveloped due to the difficulties in semen collection, semen viscosity, and semen cryopreservation. The semen collection procedure has been facilitated to some extent using camel phantom and/or possibly an intravaginal condom. Main reasons for semen viscosity in camelids have been unraveled and different mechanical and enzymatic approaches were used to alleviate this problem; however, there is still no conclusive protocol to safely remove semen viscosity completely.

Background: Plasma egg yolk (PEY), due to simple preparation and easier access, could be a suitable alternative to raw egg yolk for preserving canine semen.

Aims: The present study investigated suitable concentrations of PEY and glycerol for preservation of canine semen.

Methods: Semen was collected by digital manipulation (seven replicates from four dogs).

Serial progesterone injections followed by human menopausal gonadotropin (hMG), instead of equine chorionic gonadotropin (eCG), were used to synchronize estrus in ewes. Shal ewes (n = 189) were assigned into five groups and each group was divided into two sub-groups to receive gonadotropins including eCG (300 IU; intra-muscular) or hMG (one ampoule; subcutaneously, SC). All ewes received prostaglandin (PG) Fα six days after introducing ram (day 0).

The one carbon metabolism (OCM) has a primary role in the process of oocyte maturation. In this study bovine oocytes were cultured for 24 h, up to MII stage, with standard medium supplemented or not with 8 metabolic enhancers of the OCM and the MII and blastocyst rate were compared. Additional analyses were performed on matured oocytes, cumulus cells, zygotes and blastocysts.

Superovulation of high-producing dairy cows is a challenging subject in dairy farms with respect to the cost, dose and type of gonadotropin. The objectives of this study were to compare three gonadotropin products: Folltropin-V® (highly purified FSH with porcine origin), Cinnal-f® (recombinant human FSH) and Menotropins® (hMG) for superovulation in high-producing Holstein lactating dairy cows and to investigate the pregnancy outcomes achieved following transferring embryos recovered from donors treated with different gonadotropins. Healthy high-producing Holstein lactating dairy cows (n = 30; milk production: 46.

Objective: In the present study, we investigated the possible epigenotoxic effect of dimethyl sulfoxide (DMSO) on buffalo fibroblast cells and on reconstructed oocytes during buffalo-bovine interspecies somatic cell nuclear transfer (iSCNT) procedure and its effect on rate and quality of blastocyst which derived from these reconstructed oocytes.

Materials And Methods: In this experimental study, cell viability of buffalo fibroblasts was assessed after exposure to various concentration (0.5, 1, 2 and 4%) of DMSO using MTS assay.

Somatic cell nuclear transfer (SCNT) derived embryos suffer from abnormal epigenetic reprogramming, which handicaps pre- and postimplantation development. It was hypothesized that epigenetic modifiers, including zebularine (DNA methyltransferase inhibitors) and BIX-01294 (histone methyltransferase inhibitors), could decrease the respective levels of 5-methylcytosine and H3K9me2 in reconstructed oocytes (RO). Accordingly, we investigated whether treating RO with zebularine and BIX-01294 for 16 hours after activation could improve developmental competence and quality of buffalo-bovine interspecies SCNT (iSCNT) embryos.

The objective of this study was to investigate the effect of equine chorionic gonadotropin (eCG) on ovarian follicles at three stages of development (emergence, dominance and early static phases) during the first follicular wave (FFW) in Holstein heifers. Heifers (n=20) were randomly assigned into four experimental groups (n=5 in each group). Heifers received eCG (500 IU; Folligon; Intervet, Holland; i.

The objectives of this study were to compare three superovulation protocols and to investigate the effect of embryo diameter and shape on pregnancy rates in dromedary camel. In Experiment 1, following follicular wave synchronization of donors using two injections of GnRH (25 μg, im), superovulation was initiated 2 days after the second GnRH (Day 0 of experiment). Then, donors were assigned into three groups (n = 5) and received 1) FSH alone (390 mg), 2) eCG (1000 IU; single dose on Day 0) and FSH (330 mg) and 3) hMG (17.

Background: It has been shown that camel milk consumption has a definite decreasing effect on the prevalence of diabetes. However, most of these studies were conducted on patients with type 1 diabetes, whereas studies on patients with type 2 diabetes mellitus (T2DM) are limited. In vitro experiments have shown that camel milk was able to decrease blood glucose concentration.

Albumin is a multifunctional non-glycosylated, negatively charged plasma protein, with extraordinary ligand-binding and transport properties, antioxidant functions, and enzymatic activities. Physiologically, albumin transports free fatty acids in plasma and contributes in maintaining colloid osmotic pressure. Recent progresses in using albumin as a versatile protein carrier for drug targeting and for improving the pharmacokinetic profile of peptide or protein-based drugs, increased the attempts for improving albumin stability.
