The minimum bactericidal concentration (MBC) is the lowest concentration of an antibacterial agent required to kill a particular bacterium. [1] It can be determined from broth dilution minimum inhibitory concentration (MIC) tests by subculturing to agar plates that do not contain the test agent.
ETS sends a bulletin with a sample practice test to each candidate after registration for the exam. There are 180 questions within the biochemistry subject test. Scores are scaled and then reported as a number between 200 and 990; however, in recent versions of the test, the maximum and minimum reported scores have been 760 (corresponding to ...
The test was comprehensive and covered—in equal proportions—molecular biology, organismal biology, and ecology and evolution. [7] This exam, like all the GRE subject tests, was paper-based, as opposed to the GRE general test which is usually computer-based. It contains 194 questions which were to be answered within 2 hours and 50 minutes.
The MIT Department of Biology ("Course VII") is a center for research and teaching in the life sciences. Many members of the faculty hold joint appointments with other departments at MIT and with outside institutions.
Normal background blood and urine concentrations in healthy persons are usually less than 1 μg/litre, but they are often in the 1–10 mg/litre range (1,000–10,000 times higher) in survivors of acute intoxication. [12] [13] Thallium is present in the blood for a very short time so urine testing is usually most appropriate. A quick way to ...
[1] [2] MIC testing is performed in both diagnostic [1] [2] and drug discovery laboratories. [3] [4] The MIC is determined by preparing a dilution series of the chemical, adding agar or broth, then inoculating with bacteria or fungi, and incubating at a suitable temperature.
Whitehead Institute was founded in 1982 by industrialist and philanthropist Edwin C. “Jack” Whitehead (1920–1992), who sought to establish a research institute "dedicated to improving human health through basic biomedical science".
A laboratory rat with a brain implant, that was used to record in vivo neuronal activity. Studies that are in vivo (Latin for "within the living"; often not italicized in English [1] [2] [3]) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead organism.
