1. New treatments for rare bone diseases: hypophosphatemic rickets/osteomalacia
Abstract Phosphorus is one of the most abundant minerals in the human body; it is required to maintain bone integrity and mineralization, in addition to other biological processes. Phosphorus is regulated by parathyroid hormone, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], and fibroblast growth factor 23 (FGF-23) in a complex set of processes that occur in the gu

2. Perspectives on long-acting growth hormone therapy in children and adults
ABSTRACT Growth hormone therapy with daily injections of recombinant human growth hormone has been available since 1985, and is shown to be safe and effective treatment for short stature in children and for adult growth hormone deficiency. In an effort to produce a product that would improve patient adherence, there has been a strong effort from industry to

3. Lack of association between genetic polymorphisms in IGF1 and IGFBP3 with twin births in a Brazilian population (Cândido Godói, Rio Grande do Sul)
Abstract Insulin-like growth factor (IGF-1) is an important peptide hormone involved in the reproduction and fetal development of mammals, and it is suggested that it may influence the human twinning rate. This study aimed to test such possible association, investigating the genetic polymorphisms IGF1 (CA)n and IGFBP3 rs2854744 in the population from Candido

4. Molecular biology of human epidermal receptors, signaling pathways and targeted therapy against cancers: new evidences and old challenges
ABSTRACT Human epidermal receptors (HER1/2/3/4) belong to the class of receptor-type tyrosine kinases. After binding a ligand, dimerization, it will ocurr activation of intracellular kinases after two-dimensional and cytoplasmic tail reciprocal transphosphorylation. This transphosphorylation recruits signaling pathways such as Ras/Raf/MEK/Erk1-2, PI3-K/AKT a

5. A boy with Prader-Willi syndrome: unmasking precocious puberty during growth hormone replacement therapy
SUMMARY Prader-Willi syndrome (PWS) is a genetic disorder frequently characterized by obesity, growth hormone deficiency, genital abnormalities, and hypogonadotropic hypogonadism. Incomplete or delayed pubertal development as well as premature adrenarche are usually found in PWS, whereas central precocious puberty (CPP) is very rare. This study aimed to repo

6. The role of melatonin in diabetes: therapeutic implications
Melatonin referred as the hormone of darkness is mainly secreted by pineal gland, its levels being elevated during night and low during the day. The effects of melatonin on insulin secretion are mediated through the melatonin receptors (MT1 and MT2). It decreases insulin secretion by inhibiting cAMP and cGMP pathways but activates the phospholipaseC/IP3 path

7. Is combined therapy more effective than growth hormone or hyperbaric oxygen alone in the healing of left ischemic and non-ischemic colonic anastomoses?
OBJECTIVE: Our aim was to investigate the effects of growth hormone (GH), hyperbaric oxygen and combined therapy on normal and ischemic colonic anastomoses in rats. METHODS: Eighty male Wistar rats were divided into eight groups (n = 10). In the first four groups, non-ischemic colonic anastomosis was performed, whereas in the remaining four groups, is

8. Produção e caracterização de implantes nanotexturizados de titânio associado a liberação gradual de fármacos
The aim of this study was to assess, in vivo, the effect of two different surface treatments of titanium implants - plasma-spray (PSA) and nano-textured plasma-spray (PSA-nano) - at the bone-to-implant interface (osseointegration), associated or not to the recombinant human growth hormone (rhGH). Twenty-four prototypes of pure titanium implants, 6-mm long an

9. Mutation and genomic amplification of the PIK3CA proto-oncogene in pituitary adenomas
The tumorigenesis of pituitary adenomas is poorly understood. Mutations of the PIK3CA proto-oncogene, which encodes the p110-α catalytic subunit of PI3K, have been reported in various types of human cancers regarding the role of the gene in cell proliferation and survival through activation of the PI3K/Akt signaling pathway. Only one Chinese study described

10. Pesquisa de mutações no gene do receptor do secretagogo de hormônio de crescimento (GHSR) em crianças com baixa estatura idiopática e deficiência isolada de hormônio de crescimento / Growth hormone secretatogue receptor gene (GHSR) analysis in patients with idiopathic short stature (ISS) and patients with isolated growth hormone deficiency
A ghrelina, hormônio secretado principalmente por células gástricas, liga-se ao seu receptor, o receptor de secretagogo de GH (GHSR - Growth hormone secretagogue receptor), localizado no hipotálamo e na hipófise, estimulando a síntese e secreção do GH. Recentemente foram identificadas mutações no gene GHSR em crianças com baixa estatura idiopátic

11. Ação de fração do hormônio paratireóideo no metabolismo ósseo: estudo experimental em ratos / Effect of human parathyroid hormone fragment on bone metabolism: experimental study in rats
O hormônio da paratireóide (PTH) tem sido utilizado como um agente anabólico ósseo para o tratamento de condições de osteopenia / osteoporose, prevenção e consolidação de fraturas. O papel do fator de crescimento semelhante à insulina I (IGF-I), como um potencial mediador dos efeitos anabólicos do PTH, é controverso. O rato dwarf pode ser adequa
