The factors and mechanisms responsible for the reciprocal changes in lipogenesis in rat mammary gland and adipose tissue during the lactation cycle have been investigated. Lactation decreased the activation status and mRNA concentration of acetyl-CoA carboxylase in adipose tissue. Litter removal decreased the mRNA concentration of acetyl-CoA carboxylase in(More)
Inhibition of prolactin secretion with bromocriptine and neutralization of GH action with a specific antiserum to rat GH (rGH) were used to explore the modes of action of GH and prolactin in maintaining lactation in the rat. Treatment of dams with anti-rGH caused a small reduction in litter weight gain whilst bromocriptine reduced litter weight gain by 50%.(More)
Factors regulating the differentiation of sheep subcutaneous and abdominal (omental or perirenal) preadipocytes from foetal lambs, suckling lambs and fattening sheep have been investigated using a serum-free cell culture system. Differentiation was assessed by changes in the activity of the enzyme glycerol 3-phosphate dehydrogenase. Insulin or IGF-I was(More)
The mechanisms whereby growth hormone and dexamethasone modulate the stimulation of fatty acid synthesis by insulin in adipose tissue from lactating and non-lactating sheep have been investigated. Maintenance of adipose tissue from wethers (castrated male sheep) in tissue culture for 24 or 48 h with insulin resulted in an increased proportion of acetyl-CoA(More)
The rates of incorporation of 14C from 14C labelled acetate, glucose, alanine, leucine, isoleucine and valine into fatty acids has been measured in perirenal adipose tissue from foetal lambs and 8-month-old sheep, and into both fatty acids and acylglycerol glycerol in adipose tissue from 3-year-old sheep and 220-240 g female rats. Rates of incorporation of(More)
1. Lactation results in a substantial fall in the rate of fatty acid synthesis in sheep adipose tissue. 2. Maintenance of adipose tissue from non-lactating sheep in tissue culture for 24 or 48 h with insulin increased the rate of fatty acid synthesis. Dexamethasone, a glucocorticoid analogue, alone inhibited the rate of fatty acid synthesis, but enhanced(More)
OBJECTIVE To assess the prevalence of tuberculosis (TB) or a positive skin test in healthcare workers (HCWs) providing services to human immunodeficiency virus (HIV)-infected individuals and to determine prospectively the incidence of new infections in this population. DESIGN This prospective cohort study enrolled 1,014 HCWs working with HIV-infected(More)
INTRODUCTION The objective of this study was to develop a semiautomated approach to screening cases that describe hazards associated with the electronic health record (EHR) from a mandatory, population-based patient safety reporting system. METHODS Potentially relevant cases were identified through a query of the Pennsylvania Patient Safety Reporting(More)
The rate of noradrenaline-stimulated lipolysis is lower in fat-cells from lactating than from pregnant rats; this difference is eliminated by the addition of adenosine deaminase [Aitchison, Clegg & Vernon (1982) Biochem. J. 202, 243-247]. The activity of 5'-nucleotidase, and hence the capacity of the cells to synthesize adenosine, was the same in fat-cells(More)
The effect of lactation on the regulation of lipolysis by beta- and alpha 2-adrenergic agents and by adenosine has been investigated. When changes in adipocyte mean cell volume (which decreases with lactation) are allowed for, lactation increased the maximum response both to beta-adrenergic agents and to the adenosine analogue N6-phenylisopropyladenosine,(More)
