The kidneys play a vital role in the homeostasis status of the body. They function to remove waste product from blood, maintain the water-electrolyte balance and release hormones. Answer and Explanation:1 In normal kidneys, blood cells and plasma proteins are not filtered. This i...
Urine, the excreted fluid and waste products filtered by the kidneys, can be presumptively tested for through the presence of urea (with urease, an enzyme) or creatine (with picric acid). Also, when heated, a urine stain gives off a characteristic odor that everyone is familiar with. Urine...
Through this process, the total plasma volume of 3 l is filtered nearly 60 times per day, allowing the kidneys to have precise control and regulation over body fluid composition. Diseases of the kidney, such as acute renal failure and chronic renal failure, become apparent when the normal ...
Hemolysis is a cardinal feature of hemolytic uremic syndrome (HUS) and during hemolysis excess arginase 1 is released from red blood cells. Increased arginase activity leads to reduced L-arginine, as it is converted to urea and L-ornithine, and thereby r
(BioAssay Systems, Hayward, CA) according to the manufacturer’s instructions. The assay measures urea formed in the sample per unit time. Plasma samples were filtered using Millipore Amicon Ultra 0.5 ml 10 kDa centrifugal filters (Merck, Darmstadt, Germany) to remove urea before assaying. Alpha...
Post-operative autologous transfusion:recycling your blood after surgery. Blood lost after surgery is collected, filtered, and returned to your body. This can be done in emergency and elective surgeries. It has the advantage of eliminating or minimizing the need for someone else's blood during sur...
Blood purification is a therapy used for many disorders to “clean” the patient’s blood by removing toxins and pathogens and restoring filtered blood to the patient. It’s mostly administered to critical care patients to prevent and treat multiple organ failure. ...
A creatinine test, also called a serum creatinine test, measures how well your kidneys are working. Creatinine is a waste product from the normal breakdown of muscle tissue. As your body makes it, it's filtered through yourkidneysand expelled in urine. Doctors use your creatinine levels to es...
The supernatant was filtered by 0.22 μm pore size Merck Millipore Durapore™ PVDF Membrane Filters and subjected to Ni2+-affinity chromatography using a HisTrap Chelating column (5 mL, GE HealthCare) equilibrated in 50 mM Tris-HCl pH 7.5, 500 mM NaCl. Elution was performed with ...
When your BUN levels are compared to your creatinine levels, it gives a fuller picture of what’s happening with your kidneys. This is known as the BUN/creatinine ratio. Creatinine is a waste product from your muscles that's also filtered by your kidneys. Like BUN, high levels of creatinin...
