There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
tPA has a pivotal role in placentation, mediationg activation of growth factors, such as vascular endothelial growth factor and brain-derived neurotrophic factor, degradation of extracellular matrix and basement membrane (directly or through activation of matrix metalloproteinases) and formation of hemidesmosomes. A high-carbohydrate intake combined with lack of physical activity provides a strong stimulus for maternal insulin production. In this scenario, either β-cells are dysfunctional and diabetes supervenes, or excessive amounts of insulin are produced, providing pathological stimulation of PAI-1 synthesis. Given that PAI-1 is a major tPA inhibitor, PAI-1 excess may affect placentation, increasing the risk of first trimester losses, preterm deliveries and intrauterine growth restriction. Our hypothesis was that prematurity was not the cause of neonatal hypoglycemia, but a parallel occurrence of a strong stimulus for maternal, fetal and neonatal production of insulin.
Magnesium sulfate is the ideal drug for seizures prophilaxis in preeclampsia. The ideal duration of this treatment after delivery is still to be established. The hypothesis is that in stable patients a shorter course of treatment is possible without prejudice to the mother.
This study aims to evaluate the therapeutic effect of the infusion of Maytenus ilicifolia Mart. ex Reiss leaves, used for 8 weeks, on patients with dyspepsia. Primary endpoint is SODA score, secondary endpoint is endoscopic classification (Sydney).
The primary objective of the study is assess the safety and tolerability of long-term epratuzumab treatment in subjects with Systemic Lupus Erythematosus (SLE)
Objective: To study the effects of Tribulus terrestris on sexuality in postmenopausal women.
A multicentre, randomized, two parallel group study comparing virtual reality using Wii gaming technology versus Recreational activities in patients receiving conventional rehabilitation after an ischemic stroke. Primary Hypothesis: Virtual reality using the Wii gaming system is more efficacious in improving motor function than recreational therapy among patients receiving conventional rehabilitation following a recent ischemic stroke.
The purpose of this study is to compare effectiveness and safety of a sublingual misoprostol 12,5 mcg with vaginal misoprostol 25 mcg for induction of labour with an alive and term fetus.
The purpose of this study is to: 1. Evaluate the efficacy of Adapalene gel 0.3% compared to Tretinoin Emollient cream 0.05%, reducing signs of cutaneous photoageing, measured trough photonumeric scale evaluation, investigator evaluation of global response to treatment and subject's evaluation of improvement. 2. Evaluate the safety and tolerability of Adapalene Gel 0.3%, compared to Tretinoin Emollient cream 0.05% during 24 weeks of treatment. The study has the clinical hypothesis that Adapalene Gel 0.3% is as effective as Tretinoin Emollient cream 0.05% in the treatment of cutaneous photoaging.
The purpose of this study is to investigate the effect that obesity may have on the nonsurgical treatment (with and without the adjunct use of metronidazole) of destructive periodontal diseases (chronic periodontitis).
It is well known the efficacy of 5% 5-fluoruracil for multiple and superficial actinic keratosis (AKs)treatment. Recently its additional benefit for advanced and severe photoaging while treating Aks was reported. The aim of this study is to compare the efficacy and safety of the two modalities of 5% 5-FU use for forearms photoaging.
