  2. Contraction stress test - Wikipedia

    en.wikipedia.org/wiki/Contraction_stress_test

    The CST was the first antenatal surveillance test that was developed after the development of the cardiotocograph. [4] The oxytocin challenge test was first described in 1972 [11] and was standardised in 1975 when the parameters of contraction number and frequency were given. Historically, a CST was done after a non reactive NST.

    In these cases, the fetus would be put at an increased risk of contracting the hepatitis virus from the mother. However, the necessity of the procedure should be considered along with this risk. PUBS should not be performed in mothers testing positive for the human immunodeficiency virus (HIV) due to increased risk of fetal contraction. [29]

    during contraction, actin filaments move into the A bands and the H zone is filled up reducing its stretch, the I bands shorten, the Z line comes in contact with the A bands; and; the possible driving force of contraction is the actin-myosin linkages which depend on ATP hydrolysis by the myosin.

    Since its first scientific publication in 1990 more than 300 articles show tensiomyography use and purpose: in the estimation of muscle composition; [23] [24] for evaluating muscle atrophy; [11] for measuring adaptation to different pathologies; [10] [19] [25] for measuring adaptation to specific training; and for measuring muscle fatigue.

    The collagen gel contraction assay is an in vitro model of wound contraction. It is performed using the dermal equivalent model, ...

  7. Nonstress test - Wikipedia

    en.wikipedia.org/wiki/Nonstress_test

    A nonstress test (NST) is a screening test used in pregnancy to assess fetal status by means of the fetal heart rate and its responsiveness. A cardiotocograph is used to monitor the fetal heart rate and presence or absence of uterine contractions. The test is typically termed "reactive" (also "reassuring") or "nonreactive" (also "nonreassuring ...

    en.wikipedia.org/wiki/Leopold's_maneuvers

    Leopold's maneuvers. In obstetrics, Leopold maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus.They are named after the gynecologist Christian Gerhard Leopold.

  9. Pregnancy test - Wikipedia

    en.wikipedia.org/wiki/Pregnancy_test

    A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [1] Testing blood for hCG results in the earliest detection of pregnancy. [2]
