Detritus (/ d ə ˈ t r aɪ t ə s /; adj. detrital / d ə ˈ t r aɪ t əl /) is particles of rock derived from pre-existing rock through weathering and erosion. [1] A fragment of detritus is called a clast. [2] Detrital particles can consist of lithic fragments (particles of recognisable rock
Staphylococcus saprophyticus was not recognized as a cause of urinary tract infections until the early 1970s, more than 10 years after its original demonstration in urine specimens. Prior to this, the presence of coagulase-negative staphylococci (CoNS) in urine specimens was dismissed as contamination. [citation needed]
Urine pH may be monitored to help prevent the formation of kidney stones or to avoid side effects of some drugs, [68] such as high-dose methotrexate therapy, in which crystals that cause kidney damage can form if the urine is acidic. [69] If microscopy is performed, knowing the pH of the sample helps to identify any crystals that might be ...
Modern sealife aquariums often use the Berlin Method, which employs a piece of equipment called a protein skimmer, which produces air bubbles which the detritus adheres to and forces it outside the tank before it decomposes and also a highly porous type of natural rock called live rock where many benthos and bacteria live (hermatype which has ...
Primary red beds may be formed by the erosion and redeposition of red soils or older red beds, [3] but a fundamental problem with this hypothesis is the relative scarcity of red-colored source sediments of suitable age close to an area of red-bed sediments in Cheshire, England.
Acute tubular necrosis is classified as a "renal" (i.e. not pre-renal or post-renal) cause of acute kidney injury. Diagnosis is made by a FENa (fractional excretion of sodium) > 3% and presence of muddy casts (a type of granular cast) in urinalysis.
Urinalysis - After the patient provides a urine specimen, it is sent to the lab for analysis using a variety of methods including urine dipstick testing and microscopic examination. Because the kidney is responsible for making urine , analyzing the urine directly can provide crucial data that can help the physician diagnose nephritic syndrome ...
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system, and specimens are easy to obtain. [1]
