Managing the dominant follicle in high-producing dairy cows [PDF]
Bioscientifica Proceedings, 2010 Reduced reproductive efficiency has been reported in high-producing dairy cows. Sources of reproductive inefficiency include decreased expression of estrus, increased diameter of the ovulatory follicle and reduced fertility when cows are inseminated after estrus, increased incidence of double ovulation and twinning, and increased pregnancy loss.

The role of intra-ovarian interactions in the regulation of follicle dominance [PDF]
Human Reproduction Update, 1999 The processes that precisely control the selection of ovulatory follicles from a growing cohort are poorly understood. This reduction in follicle number occurs through several phases of selection, consequently we limit the use of the term 'selection' to the first major reduction of growing follicles, at the pre- to early antral stage. The final process

Molecular expression associated with vibrissa follicle development and differentiation [PDF]
, 2006 The hair follicle is a complex mini-organ formed as a result of epithelial mesenchymal interactions, provided by three different stem cell sources: epithelial, neural crest and mesenchymal.

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 ...

Advanced Healthcare Materials, EarlyView.Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

Follicular Dynamics in Crossbred cows undergoing prostaglandin induced luteolysis [PDF]
Veterinary World, 2008 Growth and regression of ovarian follicles were studied in crossbred cows (n=6), induced with prostaglandin (PGF2 alpha) analogue for luteolysis. After PGF2 alpha treatment, four cows (Group A) ovulated from dominant follicle of first follicular wave and
