Terms for subject Medical (3025 entries)

secondary resistance	When a drug-resistant strain of HIV emerges while a person is on antiretroviral therapy (ART) for the treatment of HIV infection.
selective His bundle pacing	SHBP	miss_c­um
selex	Systematic Evolution of Ligands by Exponential Enrichment	GhostL­ibraria­n
self-administered therapy (SAT)	A method of drug administration in which a person takes medication without being observed by a health care professional.
semen	A thick, whitish fluid that is discharged from the male penis during ejaculation. Semen contains sperms and various secretions. HIV can be transmitted through the semen of a man with HIV.
semen-derived enhancer of virus infection (SEVI)	Protein fibers found in semen that can trap HIV and help HIV attach to cells. Semen-derived enhancer of virus infection (SEVI) increases the risk of sexual transmission of HIV.
Semi-Anechoic Chamber	SAC chamber	vlad-a­nd-slav
semicoma	a semicomatose state from which a person can be aroused
seminal fluid	A thick, whitish fluid that is discharged from the male penis during ejaculation. Semen contains sperms and various secretions. HIV can be transmitted through the semen of a man with HIV.
sensitivity	The probability that a medical test will detect the condition being tested for in people who actually have the condition. In other words, a sensitive test is one that produces true positive results. For example, the enzyme-linked immunosorbent assay (ELISA) HIV antibody test is highly sensitive, which means the test can detect HIV in most people infected with HIV. However, because the ELISA can sometimes mistakenly recognize antibodies to other diseases as antibodies to HIV (a false positive result) a Western Blot or other HIV test is used to confirm a positive ELISA HIV antibody test.
sensory processing disorder	SPD	spanis­hru
sepsis	An overwhelming, life-threatening immune response to infection. Sepsis causes a systemic reaction that includes fever, chills, rapid heart rate, increased breathing rate, and possibly shock. Sepsis can also cause body organs, such as the kidneys or lungs, to fail. Sepsis is more likely to occur in people with weakened immune systems, including people with HIV, than in people with healthy immune systems.
sER	smooth endoplasmic reticulum
seroconversion	When an HIV-infected person converts from HIV negative to HIV positive by blood testing. Shortly after infection with HIV, the body begins to produce HIV antibodies. It takes the body a while to produce enough antibodies to be detected by an HIV antibody test—usually 10 to 14 days but sometimes up to 6 months. When HIV antibodies in the blood reach a detectable level, the HIV-infected person seroconverts. In other words, the person's antibody test goes from HIV negative to HIV positive.
serologic test	A blood test to detect the presence of antibodies against a microorganism. A serologic test can determine whether a person has been exposed to a particular microorganism.
seroprevalence	The overall occurrence of a disease or condition within a defined population at one time, as measured by blood tests (serologic tests)
serostatus	The state of either having or not having detectable antibodies against a specific antigen, as measured by a blood test (serologic test) For example, HIV seropositive means that a person has detectable antibodies to HIV; seronegative means that a person does not have detectable HIV antibodies.
Serostim	rhGD
Serostim	Serostim
serum	The clear, yellowish liquid part of blood that remains after clotting. Serum is used for various laboratory tests.
