The Possible Mechanisms through Which Dietary Protein Increases Renal Blood Flow and Glomerular Filtration Rate.

Obesity has been associated with a multitude of co-morbid conditions, most importantly with diabetes mellitus and cardiovascular diseases. Diet is one of the major key factors of a successful weight management schemes to ensure a healthy weight. High protein, low carbohydrate and low fat diets are reported to be effective for weight management and gained particular popularity in the recent past. As a result, most individuals have shifted to high protein diet in an attempt to lose weight or maintain a healthy weight or body composition. On the other hand, high dietary protein is well known to increase renal blood flow and glomerular filtration rate and may potentially increase the future risk of renal disease due to increased glomerular pressure and hyperfiltration injury. The mechanism by which protein diet acts on the kidney is not well known; however, multiple potential mechanisms have been postulated. This review discusses the possible mechanisms through which dietary protein intake may influence renal function parameters.

Impact of Noise Pollution on Human Cardiovascular System.

Noise pollution is one of the man-made environmental hazards that is given the least attention. By World Health Organization’s (WHO) definition, noise pollution is unwanted or excessive sound that can have deleterious effects on human health and environmental quality. Industrial facilities, entertainment joints, highway, railway, airplane traffic, construction activities and some indoor activities are major sources of noise. Prolong or frequent exposure to excessively loud noise can cause degeneration of the spiral organ resulting in high frequency deafness. Despite the awareness of noise impact on auditory function, people are still engaged in activities that generate loud noise. In some developing countries where electrical power supply is not reliable, the use of generators has contributed immensely to environmental noise. Studies have reported that noise increases the prevalence of hypertension which is one of the risk factors for cardiovascular disorders. The increasing number of hypertensive individuals in developing countries might be owed to incessant noise. If the governments of these countries do not take necessary measures to combat noise pollution, their countries might be populated with cardiovascular disease individuals
