The Mantel-Haenszel test is the most frequent asymptotic test used for analyzing stratified 2 × 2 tables. Its exact alternative is the test of Birch, which has recently been reconsidered by Jung. Both tests have a conditional origin: Pearson’s chi-squared test and Fisher’s exact test, respectively. But both tests have the same drawback that the result of global test (the stratified test) may no...

A simple and reliable cytogenetic test for Fanconi's anemia (FA) that is based on the hypersensitivity of FA cells to mitomycin C (MC) is described. Equal volumes of whole blood from a patient in whom the diagnosis of FA is suspected and from a normal person of the opposite sex are co-cultured in phytohemagglutinin-containing medium in the presence and absence of MC. After five days' co-cultiva...

BACKGROUND The purpose of this study was to examine the relationship between perceived physical competence (PPC), actual motor competence (MC) and body mass index (BMI) in young children. METHODS We assessed MC (Test of Gross Motor Development - 2nd Edition), PPC (Pictorial Scale of Perceived Competence and Social Acceptance) and BMI (CDC calculator) of 178 young children ages 4-7 years. RE...

An improved microwave coagulation (MC) method was devised for hemostasis after liver biopsy and puncture of the spleen under laparoscopy. Safety and hemostatic effects of the method were studied with the following results: 1) MC resulted in a wedge-shaped area around the electrode showing necrosis and degeneration of hepatic cells in the liver of five autopsied cases. The area of tissue damage ...

piezoelectric microcantilevers (mcs) are a new generation of microbeams used in atomic force microscopes (afms). due to their miniaturization of afms as well as their increased imaging precision and speed, these mcs are more popular than their classical counterparts. given the widespread application of these beams in nanoparticle topography, analysis of their vibrating motion has attracted much...

BACKGROUND Lactuca sativa (lettuce) has been traditionally used for relieving pain, inflammation, stomach problems including indigestion and lack of appetite. Moreover, the therapeutic significance of L. sativa includes its anticonvulsant, sedative-hypnotic and antioxidant properties. METHODS In the present study, the MC (methanol and chloroform; 1:1) and aqueous extracts of seed and leaf alo...

Given a test criterion, the number of test-sets satisfying the criterion may be very large, with varying fault detection effectiveness. This paper presents an experimental evaluation of the variation in fault detection effectiveness of all the test-sets for a given control-flow test criterion and a Boolean specification. The exhaustive experimental approach complements the earlier empirical stu...

background: there is extensive variety of chemical compounds with antiulcer activity, which are isolated from medicinal plants. matricaria chamomilla or matricaria recutita or german chamomile, also spelled chamomile (mc), is one of the most widely used medicinal plants. in the present study, the extract of mc flowers was evaluated for antiulcerogenic activity and acute toxicity profile.   meth...
