BACKGROUND & AIMS Inflammation is catabolic and causes muscle loss. It is unknown if amino acid supplementation reverses these effects during the acute phase of inflammation. The aim was to test whether amino acid supplementation counteracts endotoxin-induced catabolism. METHODS Eight young, healthy, lean males were investigated three times in randomized(More)
Tumor necrosis factor-α (TNF-α) has widespread metabolic actions. Systemic TNF-α administration, however, generates a complex hormonal and metabolic response. Our study was designed to test whether regional, placebo-controlled TNF-α infusion directly affects insulin resistance and protein breakdown. We studied eight healthy volunteers once with bilateral(More)
The 11 beta-hydroxysteroid dehydrogenase type II enzyme (11 beta HSD2) inactivates glucocorticoids in the kidney and thus prevents glucocorticoids from occupying the non-selective mineralocorticoid receptor in epithelial tissues. Mutations in the HSD11B2 gene have been found to cause the syndrome of apparent mineralocorticoid excess, a rare autosomal(More)

Determinations of platelet number and concentration of antithrombin III (AT-III) were made in samples of plasma collected during one normal or hormone-simulated cycle in 14 young, normal women and in 11 women using an oral contraceptive low in oestrogen. Distinct, individual levels caused the variation of both parameters to be greater within the group than(More)
Histidine-rich glycoprotein (HRG) has been reported to be a fibrinolysis regulating protein due to its capacity to bind to the high affinity lysine binding sites of plasminogen. Using immunological methods we have measured the concentrations in plasma of HRG and total plasminogen and calculated the amounts of plasminogen not bound to HRG (free plasminogen)(More)
BACKGROUND Lipolysis is accelerated during the acute phase of inflammation, a process being regulated by pro-inflammatory cytokines (e.g. TNF-α), stress-hormones, and insulin. The intracellular mechanisms remain elusive and we therefore measured pro- and anti-lipolytic signaling pathways in adipocytes after in vivo endotoxin exposure. METHODS Eight(More)
OBJECTIVE Acute and chronic inflammatory and metabolic responses are generated by lipopolysaccharide (LPS) during acute illness and in the pathogenesis of the metabolic syndrome, type 2 diabetes and cardiovascular disease, but whether these responses depend on intact pituitary release of hormones are not clearly identified. We compared the metabolic effects(More)
CONTEXT TNF-α generates inflammatory responses and insulin resistance, lipolysis, and protein breakdown. It is unclear whether these changes depend on intact hypothalamo-pituitary stress hormone responses to trigger the release of cortisol and growth hormone. OBJECTIVE To define differential effects of TNF-α on glucose, protein, and lipid metabolism in(More)
Scabies was recently reported for the first time in the European wild rabbit, Oryctolagus cuniculus (Lagomorpha: Leporidae). We experimentally exposed 10 seronegative wild-caught rabbits to skin from a mangy wild rabbit. Serological, physiological, parasitological and histopathological changes were recorded. Three rabbits developed antibodies at 2-5 weeks(More)
