Compromise of elastic fiber integrity in connective tissues of the pelvic floor is most likely acquired through aging, childbirth-associated injury, and genetic susceptibility. Mouse models of pelvic organ prolapse demonstrate systemic deficiencies in proteins that affect elastogenesis. Prolapse, however, does not occur until several months after birth and is thereby acquired with age or after ...

The effectiveness of dexamethasone and prostaglandin in combination for induction and synchronization of parturition in cattle was evaluated in 100 pregnant Angus, Hereford, Charolais and Simmental cows. Cows were distributed equally by breed, day of gestation and cow age to one of three treatments: 1) Control, 2) Dexamethasone (25 mg) plus prostaglandin F(2alpha) (25 mg) or 3) Dexamethasone (2...

BACKGROUND Changes in colostrum composition of Egyptian buffaloes and Holstein cows collected at calving, 6, 12, 24, 48, 72, 96, 120 h and after 14 days of parturition were studied. Total solids, total protein, whey proteins, fat, lactose and ash contents were determined. Macro- and micro-elements, IgG, IgM, IGF-1, lactoferrin and vitamins (A and E) were also estimated. RESULTS At calving, th...

Climate-induced shifts in plant phenology may adversely affect animals that cannot or do not shift the timing of their reproductive cycle. The realized effect of potential trophic "mismatches" between a consumer and its food varies with the degree to which species rely on dietary income and stored capital. Large Arctic herbivores rely heavily on maternal capital to reproduce and give birth near...

Histological changes in kidney structure following paracetamol administration in pregnant Sprague - Dawley rats were studied. Ten (10) Sprague-Dawley rats divided into five animals per group were used for the study. They were divided into two groups (A and B). Group A served as a control group, while group B received 7.3 mg x 3/kg/day of paracetamol from 10th day of gestation till the 13th day ...

Konigsson, K. 2001. Induced Parturition and Retained Placenta in the Cow. Inhibition of prostaglandin F z a synthesis and antibiotic therapy Doctor's dissertation. In order to study rapid changes in 1 5-kctodihydro-PGF2, (PG-metabolite), in the period preceding parturition in cattle, prc-term parturition was induced by dcxamcthasonc injection in four heifers on days 254 to 265 in gestation. Blo...

The stress of parturition in the dairy cow is associated with increased susceptibility to infectious disease. During the periparturient period the demands for calcium are increased; these increased demands for calcium can result in subclinical or clinical hypocalcemia. Periparturient cows also experience significant immune suppression. Because intracellular calcium signaling is a key early feat...
