Very little is known about the endocrinology of the baleen whales. The highly endangered North Atlantic right whale (NARW; Eubalaena glacialis) is a good model species, because most NARW individuals are photo-identified with known histories. We used an 125I corticosterone assay, shown to reliably measure cortisol metabolites, to determine glucocorticoid metabolite concentrations in 177 NARW fec...

introduction: previous studies have indicated that stress levels of glucocorticoid hormones induce impairment of long term memory retrieval, but the underlying mechanisms (genomic or non-genomic) are not clear. to clarify this issue, we investigated the involvement of brain corticosteroid receptors and protein synthesis in the glucocorticoid-induced impairment of memory retrieval. methods: 140 ...

  Primary Hepatic Lymphoma (PHL) is rare and possibly associated with viral hepatitis and autoimmune diseases. Scleroderma could exceptionally be complicated by lymphoma. We describe PHL occurring in a 52-year-old female suffering scleroderma for eight years, with no history of cytotoxic or high-dose glucocorticoid therapy. CT scan, performed to work-up abdominal discomfort, constipation, and ...

Altered daily patterns of hormone action are suspected to contribute to metabolic disease. It is poorly understood how the adrenal glucocorticoid hormones contribute to the coordination of daily global patterns of transcription and metabolism. Here, we examined diurnal metabolite and transcriptome patterns in a zebrafish glucocorticoid deficiency model by RNA-Seq, NMR spectroscopy and liquid ch...

Adverse early experience impairs adult learning and memory. Previously, we showed that neonatal maternal separation impaired eyeblink conditioning in adult male rats. This impairment was correlated with increases in glucocorticoid receptor expression in the posterior region of the cerebellar interpositus nucleus, a key structure in the neural circuitry controlling eyeblink conditioning. To begi...

Exposure of the Fu5 rat hepatoma cell line to glucocorticoids, such as dexamethasone and hydrocortisone, suppressed the growth rate and final density of cells grown in the presence of serum. This hormonal effect was proportional to receptor occupancy and affinity and, in addition, the glucocorticoid antagonist RU38486 prevented this response. Two classes of dexamethasone-resistant variants that...

OBJECTIVES To determine factors associated with damage accrual in a prospective cohort of patients with SLE. METHODS Patients with SLE who attended the Lupus Clinic at Monash Health, Australia, between 2007 and 2013 were studied. Clinical variables included disease activity (Systemic Lupus Erythematosus Disease Activity Index-2K, SLEDAI-2K), time-adjusted mean SLEDAI, cumulative glucocorticoi...

The early phase of hypertension induced in rats by a glucocorticoid agonist RU 26988 was studied. Systolic blood pressure increased by 35 mm Hg. Water and sodium urinary excretion increased transiently, and plasma volume decreased. Total and ouabain-sensitive sodium efflux, as well as rubidium efflux, were enhanced by glucocorticoid administration. Low salt intake did not prevent hypertension. ...

OBJECTIVES To characterize glucocorticoid receptor expression in peripheral WBCs of critically ill children using flow cytometry. DESIGN Prospective observational cohort. SETTING A university-affiliated, tertiary PICU. PATIENTS Fifty-two critically ill children. INTERVENTIONS Samples collected for measurement of glucocorticoid receptor expression and parallel cortisol levels. MEASUREM...
