Overall, the prevalence of stillbirth was 11% (n = 17).

Effects of T-2 and Fumonisin B1 combined treatment on in vitro mouse embryo development and blastocyst quality.

In the temperate region, most common mycotoxins are members of fusariotoxins. It often happens that food and forage are contaminated with two or more fusariotoxins at the same time. Effects of co-contamination are poorly documented, especially in the field of reproduction.

Equine alpha-fetoprotein levels in Lipizzaner mares with normal pregnancies and with pregnancy loss.

Alpha-fetoprotein has proved to be a good indicator of fetal well-being in human medicine for decades. Although this molecule is present in most of the mammalian species including horses, reference values in healthy and high-risk pregnant mares have not yet been published. The aim of the present study was to determine whether equine alpha-fetoprotein (eqAFP) is a good indicator of complicated pregnancies in Lipizzaner mares.

Urokinase-type plasminogen activator does not affect in vitro bovine embryo development and quality.

The effects of modification of the in vitro embryo culture media (IVC) with the addition of urokinase-type plasminogen activator (u-PA) on the yield and/or quality of bovine embryos were examined in two experiments. In Experiment 1, denuded embryos were cultured in semi-defined synthetic oviductal fluid (SOF) for seven days, while in Experiment 2 embryos were co-cultured with cumulus cell monolayer in a serum-containing SOF medium. Plasminogen activator activity (PAA) and plasminogen activator inhibition (PAI) were determined in all spent IVC media.

Different chromatin and energy/redox responses of mouse morulae and blastocysts to slow freezing and vitrification.

Background: The ability to cryopreserve mammalian embryos has become an integral part of assisted reproduction, both in human and veterinary medicine. Despite differences in the size and physiological characteristics of embryos from various species, the embryos have been frozen by either of two procedures: slow freezing or vitrification. The aim of our study was to compare the effect of slow freezing and vitrification to the chromatin structure, energy status and reactive oxygen species production of mouse morulae and blastocysts.

Effects of addition of tissue-type plasminogen activator in in vitro fertilization medium on bovine embryo development and quality.

Plasminogen activators/Plasmin system plays pivotal role in regulating reproductive functions of mammals. Here, we examined the effects of modification of in vitro fertilization medium (IVF medium) with the addition of tissue-type plasminogen activator (t-PA), on bovine embryo development and quality, assessed by quantification of expression of various genes related to metabolism, oxidation, implantation and apoptosis. In addition, plasminogen activator activity (PAA) and plasminogen activator inhibition (PAI) were measured in the spent media.

Impact of fine or large needle aspiration on the dog's testis: in vitro ultrasonographic, bacteriological, gross anatomy and histological assessment.

Despite its extensive use for evaluation of spermatogenesis and assisted reproduction, the safety and consequences of fine (FNA) and large needle aspiration (LNA) to the testicular parenchyma and its normal function have not been established. This study was performed in order to accurately assess, by serial in vitro ultrasonographic, bacteriologic, gross anatomic and histological examinations, the type and extent of the effect of FNA or LNA on the dog's testis. Twenty three sexually mature, 1 to 2 years old, healthy laboratory Beagles were randomly assigned to 2 groups: (1) 5 dogs without testicular aspiration (control group) and (2) 18 dogs in which one of their testes was aspirated using a 23 G butterfly needle and the other using a 19 G butterfly needle (experimental group).

Vitrification of cleavage stage mouse embryos by the cryoloop procedure.

By decreasing the volume of the cryoprotective solution it is possible to increase dramatically the freezing speed and - at the same time - reduce the toxicity and osmotic side effects of cryoprotectants (CPA). The objective of our study was to vitrify Day-3 cleavage stage mouse embryos (n = 229) with the cryoloop technology using a new composition of vitrification media. Embryos were exposed to a 2-step loading of CPA, ethylene glycol (EG) and propylene glycol (PG), before being placed on the surface of a thin filmy layer formed from the vitrification solution in a small nylon loop, then they were rapidly submerged into liquid nitrogen.

Effects of melatonin treatment on follicular development and oocyte quality in Chios ewes - short communication.

Follicular development and oocyte quality were assessed by laparoscopic observation and in vitro fertilisation, respectively, in melatonin-treated (Group M) and control (Group C) anoestrous Chios ewes (n = 10 in each group). Fourteen days after melatonin insertion, all ewes had laparoscopic evaluation of the follicular population followed by oocyte pick-up (OPU); on day 22 intravaginal progestagen sponges were inserted for 14 days. Two days after sponge removal the follicular population was re-evaluated and a second follicular aspiration was performed.
