Mechanical stimuli and hydrostatic pressure (HP) play an important role in the regulation of chondrocytes metabolism. Growing evidence demonstrated the ability of mechanical loading to modulate the expression of microRNA (miRNA) involved in chondrocytes homeostasis and in the pathogenesis of osteoarthritis (OA). The expression of miR-155, miR-181a and miR-223 in normal and OA chondrocyte cultures, and their potential modifications following exposure to three hours of a cyclic HP (1-5 MPa, frequency 0.25 Hz) were investigated...

BACKGROUND: Sirtuins, including SIRT1 and SIRT2, are longevity-associated deacetylase enzymes that modulate metabolic homeostasis in response to the cellular energy state. Adenosine monophosphate activated protein kinase (AMPK) and SIRT1 are interrelated and share several common target pathways. This study aimed to evaluate the SIRT1 and SIRT2 gene expression in peripheral blood mononuclear cells (PBMCs) as well as plasma levels of AMPK, in obese children and adolescents. MATERIALS AND METHODS: Participants included 60 children and adolescents (30 obese and 30 age- and gender-matched control subjects)...

OBJECTIVES: Although there is substantial evidence that psychological factors play an important role in the onset and course of cardiovascular disease (CVD), less is known about their combined effect and the pathways by which they affect cardiovascular health. The present work aimed to prospectively explore the effects of depression and anxiety on the 10-year CVD incidence, in relation to other lifestyle determinants, as linking factors in the context of the ATTICA study. Study design/Main outcome measures: The ATTICA study is a population-based, health and nutrition prospective cohort study (2002-2012), during which 853 middle-aged participants without a history of CVD [453 men (aged 45±13years) and 400 women (aged 44±18years)], underwent psychological evaluations at enrollment...

Ying Hu, Zhiqiang Chen, Ling Jin, Mei Wang, Wei Liao
BACKGROUND: The tryptophan metabolic pathway mediated by indolamine 2,3-dioxygenase (IDO), a tryptophan-degrading enzyme, plays an important role in controlling the development of allergic inflammation. The fractional concentration of exhaled nitric oxide (FeNO) is closely associated with the allergic state and is extensively used for the clinical evaluation of airway allergic inflammation. Clinical trials have rarely assessed the expression of IDO in childhood allergic asthma and its correlation with FeNO...

BACKGROUND: Vitamin D (VitD) and parathyroid hormone (PTH) play important roles in calcium metabolism and skeletal homeostasis. Estimates of the VitD status in several European countries show large variations between them. In addition, no national population-based estimate has been published. VitD and PTH may also play important roles in cardiovascular risk, which has been suggested to be associated with metabolic syndrome (MetS) and is very prevalent in Portugal. The goal of our study was to evaluate the prevalence of hypovitaminosis D and its determinants as well as PTH serum level determinants and associations of the 25-hydroxyvitamin D and PTH serum levels with MetS and its individual components in a sample of the Portuguese mainland population...

The red seaweed, Kappaphycus alvarezii, was evaluated for its potential to prevent signs of metabolic syndrome through use as a whole food supplement. Major biochemical components of dried Kappaphycus are carrageenan (soluble fiber ~34.6%) and salt (predominantly potassium (K) 20%) with a low overall energy content for whole seaweed. Eight to nine week old male Wistar rats were randomly divided into three groups and fed for 8 weeks on a corn starch diet, a high-carbohydrate, high-fat (H) diet, alone or supplemented with a 5% (w/w) dried and milled Kappaphycus blended into the base diet...

Uterine fibroids (UFs) are benign tumors of the female genital tract made of the smooth muscle of the uterus. UF growth depends mostly on the influence of the steroid hormones and selected growth factors. Transforming growth factor β (TGF-βs) is a polypeptide that consists of three isoforms: TGF-β1, TGF-β2, and TGF-β3. At present, TGF-β is considered to be one of the key factors in the pathophysiology of UFs. It plays a major role in cellular migration within the tumor, stimulates tumor growth, and enhances tumor metabolism...

Herein, we present a 14-year-old patient with short stature (134 cm) referred from Paediatrics to our department for complementary evaluation since growth hormone (GH) treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I-II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1). Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy...

Background: Thiopurines, azathioprine (AZA) and 6-mercaptopurine (6-MP) are common maintenance medications for inflammatory bowel disease (IBD). Excessive methylation via thiopurine methyltransferase (TPMT) frequently causes therapeutic failure. Allopurinol reduces excessive 6-methyl-mercaptopurine (6-MMP) while enhancing 6-thioguanine (6-TGN) levels. The aim of this study was to evaluate clinical, metabolic and endoscopic impact of allopurinol in combination with low-dose thiopurine in IBD...
