Renal function, in nephrology, is an indication of the kidney's condition and its role in renal physiology. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the kidney. Creatinine clearance rate (C or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR. Creatinine clearance exceeds GFR due to creatinine secretion, which can be blocked by cimetidine. In alternative fashion, overestimation by older serum creatinine methods resulted in an underestimation of creatinine clearance, which provided a less biased estimate of GFR. Both GFR and C may be accurately calculated by comparative measurements of substances in the blood and urine, or estimated by formulas using just a blood test result (eGFR and eC).
is creatinine clearance and gfr the same thing?

Answer: no


The apportionment of seats in this House of Representatives was based on the Nineteenth Census of the United States in 1970. Both chambers had a Democratic majority. It was the first time either party held a filibuster-proof 60% super majority in both the Senate and House chambers since the 89th United States Congress in 1965, and last time until the 111th United States Congress in 2009. All three super majorities were Democratic party and also were accompanied by Democratic Presidents. As of 2018, this is the most recent Congress to approve an amendment (the unratified District of Columbia Voting Rights Amendment) to the Constitution.
has there ever been a supermajority in congress?

Many beneficial effects of lorazepam (e.g., sedative, muscle relaxant, anti-anxiety, and amnesic effects) may become adverse effects when unwanted. Adverse effects can include sedation and low blood pressure; the effects of lorazepam are increased in combination with other CNS depressant drugs. Other adverse effects include confusion, ataxia, inhibiting the formation of new memories, and hangover effects. With long-term benzodiazepine use it is unclear whether cognitive impairments fully return to normal after stopping lorazepam use; cognitive deficits persist for at least six months after withdrawal, but longer than six months may be required for recovery of cognitive function. Lorazepam appears to have more profound adverse effects on memory than other benzodiazepines; it impairs both explicit and implicit memory. In the elderly, falls may occur as a result of benzodiazepines. Adverse effects are more common in the elderly, and they appear at lower doses than in younger patients. Benzodiazepines can cause or worsen depression. Paradoxical effects can also occur, such as worsening of seizures, or paradoxical excitement; paradoxical excitement is more likely to occur in the elderly, children, those with a history of alcohol abuse, and in people with a history of aggression or anger problems. Lorazepam's effects are dose-dependent, meaning the higher the dose, the stronger the effects (and side effects) will be. Using the smallest dose needed to achieve desired effects lessens the risk of adverse effects. Sedative drugs and sleeping pills, including lorazepam, have been associated with an increased risk of death.
can lorazepam be used as a muscle relaxer?
