CDGP is a common growth disorder, often dominantly inherited. Genetic association is thus very likely. There are many possible candidates but none are yet linked to CDGP. We assessed the possible contribution of L, LR genes (mutations in each cause very delayed or absent puberty), CART (mediates the effect of L on GnRH pulse generation), and GPR54 (a hypothalamic G-protein coupled receptor, which is mutated in familial hypogonadotrophic hypogonadism) genes.<p class="abstex...

The importance of the sRANK-L / RANK / Osteoprotegerin (OPG) system in osteoclast function has clearly been demonstrated in the rat. Activating and inactivating mutations lead to severe disturbances of bone remodelling.Since this early animal work, there have been several studies designed to assess the importance of sRANK-L / RANK / OPG in diseases of the human skeleton. sRANK-L and OPG are measurable in blood.This cross-sectional ...

Objective: Cathepsin L can control adipogenesis and relate to acute coronary syndrome. However, it is not clear whether cathepsin L can be affected by saturated fatty acid and decrease by curcumin. We examined the hypothesis that palmitate upregulates cathepsin L expression in adipose tissue and curcumin can be block that effect.Methods: 3T3-L1 cells were fully differentiated for 8 to 10 days and treated with palmitate, LPS, IL6, TNF-α, IL6 neutrali...

Background: Mitotane antitumor efficacy is related to plasma levels. Objective responses have been associated with mitotane plasma levels >14 mg/l. However, high plasma levels >20 or >30 mg/l are at higher risk of toxicity, especially neurotoxicity. National-based survey is lacking to evaluate the frequency and severity of high mitotane plasma levels. Our aim was to retrospectively describe serious adverse events (SAE).Methods: Mitotane plasm...

In pregnant women with thyroid diseases an increased amount of LT4 may be required for the correction of hypothyroidism or treatment of nodular goiter. Aim of this study was to assess the amount of the variations of LT4 requirement in pregnant women with thyroid diseases. To address this issue, we retrospectively evaluated a cohort of 107 women treated with LT4 divided in two groups: 42 euthyroid (E) (affected by nodular goiter (NG) treated with LT4 suppressive therapy) and 65...

The TNF members sRANK-L & Osteoprotegerin (OPG) are essential paracrine mediators of osteoclast function in vitro. The aim of this study was to establish the relationship between 25-hydroxyvitamin D and sRANK-L and OPG in plasma of osteoporotic patients.The study population consisted of 185 osteoporotic women (mean age 62.4 years), with bone mineral density (BMD) more than 2.5 SD below the young adult value, and 185 age-matched controls, with normal ...

The Osteoprotegerin (OPG) RANK and RANK-L system is a novel paracrine system that forms part of the mechanism of bone turnover. The aim of this study was to explore if the OPG/ RANK-L system, detectable in blood, is related to bone mineral density.The study population consisted of 185 osteoporotic women (mean age 62.4 years), with bone mineral density (BMD) more than 2.5 SD below the young adult value, and 185 age-matched controls, with normal bone miner...

In humans, pregnancy is considered a diabetogenic event1. A similar situation occurs in sows1. The amount of fat in the sows' diet is inversely correlated to glucose clearance time, thus modifying glucose tolerance2. The aim was to investigate the influence of altered maternal diet during gestation (term = 115days) on the glucose tolerance of the sow. Thirty-four pregnant sows were randomly allocated to 4 isocaloric diets for either the first (G1) or second (G2) 60 days of ges...

Background: Subclinical hypothyroidism (SCH) has been reported as a potent risk factor for cardiovascular disease, independent of cholesterol levels. Endothelial dysfunction, which is the earliest manifestation of atherosclerosis, may account for some of this cardiovascular risk. It has never been studied in a randomised controlled manner whether L-thyroxine therapy improves endothelial function.Methods: 100 patients with SCH (mean TSH of 6.6 mIU/L and n...
