Changes in the hypothalamus-pituitary-adrenal axis (HPAA) function, entailing elevated cortisol circulating titres, occur in aging and in some neurological conditions, such as Alzheimer's disease (AD). Excess cortisol has neurotoxic effects which affect hippocampal neurones. Dehydroepiandrosterone sulphate (DHEAS) has an antiglucocorticoid activity and(More)
Alterations in the hypothalamic-pituitary-adrenal axis (HPAA) and failure of dexamethasone (DXT) to suppress cortisol secretion occur in Alzheimer's disease (AD). This study was aimed to settle possible differences in some clinical (age, body weight, body mass index, dementia severity) and hormonal parameters in AD patients non-responders to overnight 1(More)
The taxonomy of Sattleria Povolný from the high mountain systems on the Balkan Peninsula and the adjacent parts of the Alps (south-eastern Alps, Dinaric Alps, Rila Mountains) is revised based on recently collected material and re-examined museum vouchers. Adult morphology and molecular data of the COI barcode region support the existence of six strictly(More)
The first line of treatment for active acromegaly is still neurosurgery followed by radiotherapy. Octreotide (1), slow-release (SR) lanreotide (2) and octreotide LAR (3) are currently administered before surgery or in patients in whom surgery and/or radiotherapy have failed to restore normal growth hormone (GH)/insulin-like growth factor-I (IGF-I) levels.(More)
