Renal denervation ameliorated salt-induced hypertension by improving cardiac work, cardiac enzyme and oxidative balance in Sprague-Dawley rats.

Background: Hypertension is associated with cardiovascular dysfunction, dysregulation of the antioxidant system and alteration of the level of some enzymes in the metabolic pathway. The possible modulatory effect of acute renal denervation (ARD) on cardiovascular function and the antioxidant system is still a subject of intense debate. This study sought to ascertain the ameliorative effects of ARD on cardiovascular parameters, antioxidant system, creatine kinase and lactate dehydrogenase levels.

Determination of Streptococcus Mutans and Lactobacillus Counts and their Association with Resting pH of Saliva and Dental Caries in Preschool Children in Lagos.

Background: Caries is controlled by several factors including exposure to diets rich in carbohydrates, tooth susceptibility, and the presence of some oral flora bacteria such as Streptococcus mutans (S. mutans) and Lactobacilli sp. Tooth demineralisation occurs when the pH in the oral cavity is lower than the critical pH of 5.

L-Arginine supplementation enhanced expression of glucose transporter (GLUT 1) in sickle cell anaemia subjects in the steady state.

L-Arginine may have therapeutic value in the management of sickle cell disease and diabetes mellitus. There is very little information on the interaction of GLUT 1 and L-Arginine in sickle cell disease subjects. This study compared the blood levels of Glut 1, fasting blood glucose (FBG) and fasting insulin (FIns) in non-sickle cell anaemia (HbAA) and sickle cell anaemia (HbSS) subjects in the steady state before and following L-Arginine supplementation (1 g/day for 6 weeks).

Effect of rapid eye movement sleep deprivation during pregnancy on glucocorticoid receptor regulation of HPA axis function in female offspring.

Poor maternal sleep quality during the different phases of pregnancy acts as a prenatal stress and is critical for fetal development. Despite the potential adverse effects of maternal stress on the behavior and physiology of the offspring, the mechanisms remain poorly understood. The present study investigates the effects of maternal sleep deprivation (SD) at different stages of pregnancy on the hypothalamic-pituitary-adrenal (HPA) axis in female offspring.

Blood pressure, hematologic and biochemical changes following L-arginine supplementation in children with sickle cell anaemia already on hydroxyurea therapy.

Hydroxyurea is an approved therapy in the management of children suffering from sickle cell disease (SCD). In adults co-administration of hydroxyurea and L-Arginine in adult sufferers of SCD had shown some benefits. This study examined the effect of co-administration of hydroxyurea (15-35mg/kg/day) and L-Arginine (500 mg/day) for 6 weeks on blood pressure, haematological parameters, liver and antioxidant enzymes levels.
