Americans (Hispanic or Latino Populations‚ 2015). Each of these conditions is a type of kidney disease in which the kidneys cannot effectively filter wastes from the blood. Chronic Kidney Disease‚ or CKD‚ can lead to many severe health problems. Because the kidneys filter the blood‚ CKD can cause the body to retain fluid that can lead to swelling‚ high blood pressure‚ or fluid in the lungs (National Chronic Kidney Disease Fact Sheet 2014‚ 2014). CKD can also cause potassium levels to rise to dangerous

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

How can AKI be prevented? According to the National Confidential Enquiry into Patient Outcome and Death 2009‚ up to 30% of cases of acute kidney injury may be preventable and the best ’treatment of AKI is prevention.’ [3]This can mainly be done by identifying patients most at risk as early as possible. This would involve constant monitoring of urinary output and serum creatinine levels for the high risk patients. However in general‚ all hospitalized patients with acute illness should be monitored

Better known for their ability to process waste‚ the kidneys are responsible for the secretion of four different hormones: rennin‚ calcitriol‚ erythropoietin and thrombopoietin These chemicals released by the kidneys affect a wide range of bodily processes dealing with the circulatory and skeletal systems. Understanding the endocrine functions of the kidneys is necessary to understand the full impact the kidneys have on the body. Rennin is a proteolytic enzyme responsible for
