background: follicle stimulating hormone (fsh) plays an essential role in reproductive physiology and follicular development. objective: a new variant of the equine fsh (efsh) gene was cloned, sequenced, and expressed in pichia pastoris (p. pastoris) gs115 yeast expression system. materials and methods: the full-length cdnas of the efshα and efshβ chains were amplified by reverse transcription ...

Background: One of the key questions in biochemistry is why cell becomes aged and what are the involved factors? Why cell growth is stopped after some divisions and cells become senescent? This occurs in a greater frame in the whole body and cells dye after a while. Androgenetic alopecia (AGA) is characterized by a loss or decrease in hair follicle size, which could be related to the loss of ha...

Background: Radioiodine is routinely used or proposed for diagnostic and therapeutic purposes: I, I and I for diagnostics and I and I for therapy. When radioiodine-labelled pharmaceuticals are administered to the body, radioiodide might be released into the circulation and taken up by the thyroid gland, which may then be an organ at risk. The aim of this study was to compare dosimetric properti...

BACKGROUND RADIOIODINE IS ROUTINELY USED OR PROPOSED FOR DIAGNOSTIC AND THERAPEUTIC PURPOSES: (123)I, (125)I and (131)I for diagnostics and (125)I and (131)I for therapy. When radioiodine-labelled pharmaceuticals are administered to the body, radioiodide might be released into the circulation and taken up by the thyroid gland, which may then be an organ at risk. The aim of this study was to com...

The ordered changes which occur in the structural organization of the mouse oocyte nucelus during the preparatory, the maturative and the preovulatory stages of antral follicle development, have been studied under both light and electron microscopy. All observations have been made on those antral follicles whose development is initiated on postnatal day 14 and completed by postnatal day 28 in p...

We aimed to quantify the number, type and arrangement of skin follicles in Huacaya and Suri alpaca skin and correlate their follicle characteristics with fibre traits of harvested fibre and compared these relationships with those of Merino sheep. Fibre and skin samples were collected from the mid-side of 12 Huacaya alpacas, 24 Suri alpacas and 10 Merino sheep. The mean fibre diameter (MFD s.e.)...
