Contribution of the VEGF system to the follicular persistence associated with bovine cystic ovaries.

Published in Theriogenology

Cystic ovaries (CO) characterize a disorder frequently found in dairy cattle. However, despite the contributions by several researchers, the mechanism that leads to ovulatory failure has not yet been completely elucidated. Thus, the aim of this study was to examine the mRNA expression of bovine vascular endothelial growth factor (VEGFA)-164, VEGFA-...

The effect of low intensity laser irradiation of inflamed udders on the efficacy of antibiotic treatment of clinical mas...

Published in Veterinaria italiana

The aim of the study was to evaluate the effect of STP-99 laser irradiation applied locally to inflamed cow udders on the efficacy of clinical mastitis treatment with either intramammary infusions of antibiotic products or systemic injections of antibiotics. Examinations were carried out on 124 milking dairy cows suffering from clinical, bacterial ...

Contribution of milk mid-infrared spectrum to improve the accuracy of test-day body weight predicted from stage, lactati...

A regular and repeated recording of body weight (BW) is useful information for herd management. BW can bepredicted regularly from animal characteristics such as age, lactation number, or lactation stage. Those traits areunfortunately animal unspecific. Adding animal specific information, which can be easily obtained on a largescale, to the BW predi...

Evaluation of the immune status of peripheral blood monocytes from dairy cows during the periparturition period.

Published in The Journal of reproduction and development

Calving is a critical but stressful event required for milk production in dairy cows. In the present study, we investigated the immune status of peripheral blood mononuclear cells (PBMCs) isolated from periparturient cows to better understand and, thus, possibly prevent stress during the periparturient period. To evaluate the immune response of PBM...

Deoxynivalenol induces apoptosis and disrupts cellular homeostasis through MAPK signaling pathways in bovine mammary epi...

Published in Environmental pollution (Barking, Essex : 1987)

Deoxynivalenol (DON), a fungus-derived mycotoxin, also known as vomitoxin, is found in a wide range of cereal grains and grain-based food products. The biological toxicity of DON has been described in various species, but its toxicity and functional effects in mammary epithelial cells are unclear. In this study, we investigated the effect of DON on...

Exosome-derived uterine microRNAs isolated from cows with endometritis impede blastocyst development.

Published in Reproductive biology

As a common disease of cows occurring during their perinatal period, endometritis is known to affect fertility. At present, the studies on endometritis mainly focus on preventing microbial invasion. However, the mechanism that uterine inflammation affects embryo activity and implantation is unclear. Mainly containing lipids, proteins, mRNAs, and mi...

Do arachidonic acid metabolites affect apoptosis in bovine endometrial cells with silenced PPAR genes?

Published in Prostaglandins & other lipid mediators

Peroxisome proliferator-activated receptors (PPARs) are expressed in bovine uterus, and their agonists are arachidonic acid (AA) metabolites. We hypothesised that silencing of PPAR genes in bovine endometrial stromal cells (ESC) would change the intracellular signalling through PPAR and affect apoptosis after cell treatment with different AA metabo...

Differential expression of miRNAs in milk exosomes of cows subjected to group relocation.

Published in Research in veterinary science

This study examined microRNA (miRNAs) expression and regulatory patterns from milk exosomes of cows experienced group relocation, a common husbandry practice during the lactation period and used as a spontaneous model of stress. Total RNA from milk exosome samples was collected from 3 cows that showed an increased milk cortisol (HRC) after relocati...
