Brown adipose tissue (BAT) activity is a relevant component of energy expenditure in mammals. Moreover, BAT constitutes an active site of glucose and lipid draining and, therefore, BAT activity is also a relevant actor in the control of glycemia and lipidemia. Recent years, possibly because of the awareness that active BAT is present in adult humans, have witnessed a burst in the identification of novel endocrine factors released by peripheral tissues that can act on BAT beyon...

The gonadal axis is an important modulator of both energy balance and metabolism. Estradiol administration to either ovariectomized female or male rats leads to inhibition of food intake and decreased body weight. Other studies have suggested the presence of estrous cycle variation in meal size and body weight in rodents, as well as during pregnancy and lactation. Recent data also indicate that estradiol modulates the appetite responses to central and peripheral signals and th...

Introduction: Thyroid hormones (TH) are essential regulators of metabolism and increase energy expenditure (EE). Mitochondria-rich brown adipose tissue (BAT) is specialised in thermogenesis and significantly contributes to EE. BAT contains essential components of TH action but TH transporters like MCT8 have not been characterised so far. As direct effects on O2 consumption and mitochondrial action have not been investigated before we tested MCT8 expression and direct effects o...

Objectives: Glucocorticoids (GCs) intervene in different physiological activities in almost all systems of the human organism. However, GCs are also potent inducers of apoptosis in many cell types and tissues. It is known, that glucocorticoid-induced apoptosis affects the musculoskeletal system, circulatory system, nervous system, endocrine system, reproductive system, and the immune system. Nevertheless, the exact mechanisms of GCs action in human normal hematopoiesis are sti...

Pituitary tumor is a rare endocrine disorder. In the majority of cases, they are secreting prolactin and/or GH. Pituitary metastatic tumors are localized more often in the nervous than adenomatous hypophysis. Lung, breast and large intestine cancers metastases are found in the pituitary in the most cases. They cause hypopituitarism and local complications. The most often complications found are an optic nerve chiasm pressure or infiltration with a visual field loss, cavernous ...

Introduction: Neurohormonal diabetes insipidus (DI) is a rare disorder caused by partial or total vasopressin deficiency which results in diluted urine characterized by polyuria and polydipsia. In 30–50% of the cases the cause of the disease is unknown; it is the so-called idiopathic diabetes insipidus. Other causes include: tumors of the CNS most commonly craniopharyngioma, pituitary macroadenomas, central nervous system trauma, inflammatory state of hypothalamus or pitu...

Introduction: Type 1 diabetes mellitus (T1DM) and multiple sclerosis (MS) are organ-specific autoimmune diseases. Their association, first described in a study in Sardinia, left questions about their clustering, clarified by the Familial Autoimmune and Diabetes Study, which showed for the first time an highly increased prevalence of MS in adults with T1DM, reinforced by further epidemiological studies that also revealed increased risk of T1DM in MS patients.<p class="abste...

Introduction: PATRO adults is an ongoing, international, open, longitudinal, non-interventional study of the long-term safety and efficacy of Omnitrope (Sandoz), a recombinant human GH (rhGH). This study will provide additional data on the long-term safety of rhGH in adult patients with severe GH deficiency (GHD). Here, we present safety data from an interim analysis.Methods: Eligible patients are male or female adults who are receiving treatment with Om...

Background: Hyponatremia is the most common electrolyte disturbance in hospitalized patients and associated with a substantial morbidity and mortality. Symptoms of severe hyponatremia vary among patients between nonspecific symptoms such as nausea or malaise or acute life threatening brain oedema. Prospective studies to assess symptoms and mortality in patients with severe hyponatremia are lacking.Methods: In this prospective multicentre observational st...

Bilateral ovariectomy (OVX) in female rats cause neurodegeneration in the nervous system of rodents and imitates systemic disorders in postmenopausal women’s organism. Synaptic modulation by estrogen is essential to understand the molecular mechanisms of estrogen replacement therapy. The aim of present work was to determine the action of Sinestrol on rats’ hippocampal synaptic transmission, plasticity and cell survival in condition of bilateral OVX. Electrophysiologi...
