Filter by:Asthma, a prevalent chronic respiratory affliction, significantly impinges upon the quality of life for affected individuals. Timely and appropriate diagnostic measures, coupled with efficacious therapeutic interventions, are paramount in mitigating exacerbations of symptoms and enhancing the life quality of patients. Ezrin plays an important role in maintaining cell morphology, cell migration, cell adhesion and polarisation, but Ezrin expression in airway smooth muscle remains unclear. Pip5k1α is an important kinase involved in intracellular phosphatidylinositol signalling pathways that may be involved in smooth muscle contraction and diastole. Therefore, further studies are necessary to elucidate the changes of Ezrin and Pip5k1α in patients with asthma to provide a basis for investigating alternative treatments for asthma.
The investigators have designed a 2-center, pilot feasibility, randomized controlled trial (PROXIMUS) to determine the feasibility and safety of a larger multi center, randomized open-label trial comparing high protein combined with individualized exercise vs. standard management during the acute phase of critical illness in children. The investigators aim to determine the impact of the intervention on preservation of muscle mass; and functional status at 1 month and 6 months after randomization.
The study aims to determine in healthy subjects the bioavailability of protein and amino acids of 4 protein sources: sunflower, rapeseed, lupin, flax. For this purpose, the investigators will compare two methods: 1. the standard method consisting in measuring the ileal digestibility using ileal tubes 2. an alternative method that has been proposed by an Food and Agriculture Organization (FAO) expert group: the dual isotope method
The objective of the study is to assess the effect of low-calorie diets with normal (18%) vs. high (35%) protein (mainly coming from animal source) composition on body weight and carbohydrates metabolism in overweight and obese subjects with pre-diabetes or diabetes. A dietary intervention is carried out during 6 months in 100 subjects who are individually randomized to an energy-restricted diet with two types of macronutrients composition: 1) 35% protein, 30% fat and 35% carbohydrates and 2) 18% protein, 30% fat and 52% carbohydrates. Around 80% of total protein in diet comes from animal source (of whom around 40% from lean red meat). Subjects are provided with weekly menus and different recipes to use them as part of the diet. Monitoring visits with the nutritionist will be performed every 15 days. At the beginning of the study, after 3 and 6 months, the following parameters are determined: anthropometric (weight, waist circumference, body mass index and body composition), blood pressure, dietary (72-hours dietary registry) and exercise and biochemical analysis (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, apolipoproteins A1 and B, iron, transferring, ferritin, uric acid, glucose, HbA1c, insulin, adiponectin and resistin). Urine samples are also collected to assess microalbuminuria and ureic nitrogen.
