Oocyte quality in small antral follicles in the presence or absence of a large dominant follicle in cattle [PDF]

Reproduction, 1996
Abstract The aim of these experiments was to determine whether the presence of a dominant follicle affects the developmental competence of oocytes from small antral follicles of cattle. In Expt 1, oocytes or follicular fluid samples were collected from follicles 2–7 mm in diameter before (day 3 of the oestrous cycle; n = 4) or after ...

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Corpus luteum development and its morphology after aspiration of a preovulatory follicle is related to size and steroid content of the follicle in dairy cows

Veterinární Medicína, 2013
Secretion of adequate levels of progesterone from a proper corpus luteum (CL), which develops out of the cells of a healthy preovulatory follicle, is a key-factor for establishment of a pregnancy. The aim of this study was to investigate the relationship

Using cell‐free RNA to identify B‐ and T‐cell clonality for diagnosis and monitoring of B‐ and T‐cell neoplasms

FEBS Open Bio, EarlyView.
Using peripheral blood for determining B‐cell or T‐cell clonality is more reliable when we use cell‐free RNA (cfRNA) because cells release blood significantly more RNA than DNA. Next‐generation sequencing (NGS) of cfRNA allows us to evaluate fragment cfRNA and evaluate clonality reliably without the need for prior determination of the specific dominant

Effect of breeding season and age on follicular dynamics and hemodynamics in embryo donor mares subjected to luteolysis after embryo flushing

Open Veterinary Journal
Background: Mares are the only companion animal simulating women in the large diameter of their follicle, the effect of aging on reproduction and even mares are more sensitive to summer heat stress as they can sweat like human.

ULTRASONOGRAPHIC EVALUATION FOR THE EFFECT OF POSTPARTAL OVARIAN ACTIVITY AND UTERINE INVOLUTION ON SUBSEQUENT REPRODUCTIVE PERFORMANCE OF DAIRY COWS [PDF]

Assiut Veterinary Medical Journal, 2005
The objective of this study was to test the hypothesis that presence of dominant follicle  in the ovary ipsilateral to the previously gravid uterine horn (PGH), between 2  and  4 weeks postpartum, improves subsequent reproductive performance. A total 28

Tuning Mechanoreceptor Signaling Enhances the Adjuvant Effect of Biomaterial Vaccines

Advanced Functional Materials, EarlyView.
Matrix stiffness serves as an independent immunological signal in biomaterial vaccines. Stiffer microporous hydrogel vaccines enhance dendritic cell maturation and migration to draining lymph nodes, promote T follicular helper cell expansion through Yap/Taz signaling, and increase antigen‐specific antibody production.

Effect of negative energy balance on plasma metabolites, minerals, hormones, cytokines and ovarian follicular growth rate in Holstein dairy cows

Journal of Veterinary Research, 2021
The aim of this study was to evaluate the effect of negative energy balance (NEB) on the final growth of the dominant ovarian follicle in Holstein cows.

Reproductive performance of fixed-time artificial insemination in heifers supplemented with a homeopathic complex

Semina: Ciências Agrárias, 2022
For this study, ½ blood nelore × aberdeen angus heifers (n = 40; 14 months) were divided into two groups: control (n=20; 310 kg) and pró-cio (n=20; 304 kg).

Effects of the Persistent Dominant Follicle on the Ability of Follicle Stimulating Hormone to Induce Follicle Development and Ovulatory Responses

Journal of Dairy Science, 2001
Three experiments were conducted to evaluate the effect of an induced first wave persistent dominant follicle on folliculogenesis and ovulatory responses induced by FSH. On d 6 of a synchronized estrous cycle (d 0 = estrus), cows were treated with a Syncromate-B implant and two injections of PGF2, (25 mg, 0700 h; 15 mg, 1900 h, i.m.).
