Investigating the KNDy hypothesis in humans by co-administration of kisspeptin, neurokinin B and naltrexone in men [PDF]

open access: yes, 2016
Context: A subpopulation of hypothalamic neurons co-localise three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin collectively termed KNDy neurons. Animal studies suggest they interact to affect pulsatile GnRH release (KNDy hypothesis);

Assessing Clinical Severity and Prognosis in Adolescents With Anorexia Nervosa and Atypical Anorexia Nervosa Using the Albumin‐Globulin Ratio

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective The albumin‐globulin ratio (AGR) is a biochemical marker reflecting nutritional and inflammatory status, with significant prognostic value in chronic conditions. This study examined its association with clinical/biochemical markers in adolescents with anorexia nervosa (AN) and atypical AN (AAN).

Transcriptomic signatures reveal systemic adaptations and immune modulation in response to training and competitive racing in horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background The molecular mechanisms underlying adaptation to physical exertion and racing stress in horses remain incompletely understood. Peripheral blood transcriptomics offers a minimally invasive method to monitor systemic responses to exercise and identify biomarkers of adaptation or overload. Objectives To evaluate transcriptomic changes

Variations of Steroid Hormone Metabolites in Serum and Urine in Polycystic Ovary Syndrome after Nafarelin Stimulation: Evidence for an Altered Corticoid Excretion. [PDF]

open access: yes, 1995
To evaluate the clinical relevance of testing pituitary-ovarian responses in patients suffering from polycystic ovary syndrome (PCOS) with the GnRH agonist nafarelin, a 1.2-mg dose of nafarelin was given intranasally to 19 women with PCOS and 15 healthy ...
