Global and regional systolic function during exercise were studied at cardiac catheterization with biplane cineangiography and micromanometer pressures in three groups of patients: an ischemia group (n = 22) with exercise-induced asynergy from coronary artery disease, a control group with no or minimal cardiovascular disease (n = 5) and a "scar" group (n = 5) with prior infarction and no new as...

1. The reduction of NAD(+), by an enzyme preparation from rat liver, in the presence of 2-mercaptoethanol is reported. 2. It is suggested that the NAD(+)-linked alcohol dehydrogenase in the extract transfers hydrogen from 2-mercaptoethanol to NAD(+). 3. Both yeast and horse-liver alcohol dehydrogenases were observed to reduce NAD(+) in the presence of 2-mercaptoethanol. 4. Some interactions of ...

A single cross-sectional study for serum copper and zinc levels was evaluated in 20 patients with cancer (respiratory, digestive, haematological, gynaecological) and 21 patients with cardiopathy (acute myocardial infarction and ischemic cardiomyopathy). A control group of 84 healthy subjects was selected. The mean serum zinc levels in patients with gynaecological cancer and ischemic cardiomyopa...

The availability of use of mouse peritoneal lymphocytes as target cells for analyzing sister chromatid exchanges (SCE) upon exposure to a genotoxic drug, cyclophosphamide, was investigated using female ICR mice. Use of these cells overcame the difficulty in use of mouse lymphocyte cultures, recovering sufficient metaphase cells. The greatest advantage of use of peritoneal lymphocytes was that a...

background the sitting position, rather than squatting, during defecation has been hypothesized to be a risk factor for colorectal cancer (crc). methods we conducted a case-control study to test this hypothesis. a total of 100 crc cases from two hospitals in iran and 100 control subjects, selected from the coronary care unit (ccu) of those same hospitals were selected for this study. we adminis...

The virulence of Pasteurella multocida (P. multocida) serotype A1 for chickens and mice was determined. Groups of chicken and mice were exposed intramuscularly and intraperitoneally to various concentration of P. multocida broth culture, respectively. This strain was highly virulent for chickens so that those exposed to only 7 c.f.u. of the organism died in less than 24 hours. Groups of mice ex...

Background: The present study aimed to compare the complete blood count (CBC) indices between COVID-19 patients and the control group, and assess the relationship of these indices with COVID-19 prognosis given the role of complete blood counts in the COVID-19 prognosis.
