The current study assessed the olfactory sensitivity of the goldfish (Carassius auratus L.) to the catecholamines, their immediate precursors and metabolites by use of the electro-olfactogram (EOG). The olfactory system of the goldfish was found to be sensitive to both adrenaline and dopamine with thresholds of detection of 10(-7.8) and 10(-7.9) M respectively, but less so to noradrenaline (thr...

Sexual precocity is considered to be present when indications of genital maturation become apparent in boys before the age of 10 years and in girls before the age of 8 years (Seckel, 1946). It is customary to divide these cases into two groups. In those with true precocious puberty maturation with spermatogenesis or ovulation has occurred in a normal manner, but at an abnormally early age; in t...

OBJECTIVE Early bonding by skin-to-skin contact (SSC) has been demonstrated to be beneficial for mothers and newborns following vaginal delivery. The aim of this study was to investigate the impact of intraoperative bonding (early SSC) after cesarean section on neonatal adaptation, maternal pain and stress response. STUDY DESIGN This prospective, randomized-controlled pilot study was performe...

BACKGROUND Hypoxia inducible factor-1α (HIF-1α) is the central transcriptional regulator of hypoxic responses during the progression of pituitary adenomas. Although previous immunohistochemical studies revealed that HIF-1α is expressed in adreno-cortico-tropic-hormone (ACTH) pituitary adenomas, the role of HIF-1α remains unclear. METHODS AtT-20 cells were incubated under hypoxic conditions (1...

Adrenomyeloneuropathy (AMN) is a disorder due to a disturbance in the peroxisomal beta-oxidation of saturated very long chain fatty acids. It is characterized by symptoms of the nervous as well as the endocrine systems, especially the adrenal cortex and the gonads. We investigated the testicular function in 49 male AMN patients aged 36.2 +/- 1.5 years (range, 18.5-59 years). Twenty-four of thes...

The use of urinary cortisol (UC) as an additional tool to evaluate sows welfare was assessed in two experiments. In a preliminary methodological experiment, the kinetics of cortisol excretion in urine was studied during an Adreno Cortico Trophic Hormone (ACTH) challenge test in 10 pregnant sows. In a second experiment, 96 primiparous sows of an experimental unit were assigned to two different h...

The aim of this study was to assess the stress-related responses and the coach's capability to match perceived efforts of youth athletes during a taekwondo championship.Using a cross-sectional study design, salivary cortisol (sC) and alpha-amylase (sAA) were measured in 6 males and 3 females young (11.0 ± 0.9 years) athletes at awakening, 5 minutes before, and 1 minute and 30 minutes after offi...

Individual variation in behavioral coping strategies to stress implies that animals may have a distinct physiological adaptation to stress; these differences may underlie differences in vulnerability to stress-related diseases. This study was designed to test the hypothesis that different behavioral coping strategies (active vs. passive) are stable over time and that they would be associated wi...
