Growth after Hypophyseal Stalk Transection and Hypophysectomy in Beef Calves

Growth hormone (GH) is a metabolic hormone that plays an important role in long-bone growth and muscle accretion in mammals. The anterior pituitary gland at the base of the brain is the primary site of GH production and release into the general circulation. Neurons in the arcuate nucleus of the hypothalamus in the lower part of the brain secrete GH-releasing hormone ([GHRH] or factor [GRF]) and...

Pregnancy, parturition, and lactation in hypophyseal stalk-transected beef heifers.

Progesterone secretion is crucial for maintaining pregnancy to parturition in mammalian species, and in cattle the corpus luteum is the primary source of this hormone. This study determined the roles of prolactin (PRL), growth hormone (GH) and luteinizing hormone (LH) in the luteotropic process in beef heifers hypophyseal stalk-transected (HST, n=7) or sham operated (sham operated controls, SOC...

Rapidly Progressive Dementia.

PURPOSE OF REVIEW This article presents a practical and informative approach to the evaluation of a patient with a rapidly progressive dementia (RPD). RECENT FINDINGS Prion diseases are the prototypical causes of RPD, but reversible causes of RPD might mimic prion disease and should always be considered in a differential diagnosis. Aside from prion diseases, the most common causes of RPD are ...

Rapidly Progressive Glomerulonephritis

Rapidly Progressive Glomerulonephritis are a group of renal diseases which are still posing serious threat to human health and survival. They are all characterised by acute and rapid deterioration of renal function. Renal biopsy reveals extracapillary glomerulonephritis, most frequently circumferential and diffuse, and immunofluorescence findings continue to represent the most important clue to...
