1. From the latex of two members of the plant family Euphorbiaceae, Hura crepitans L. (sand-box tree) and Euphorbia characias L. (Mediterranean spurge), two lectins were purified by affinity chromatography on acid-treated Sepharose 6B followed by elution with D-galactose. 2. The lectin from E. characias is a single molecular species with Mr 80 000, made up of two identical subunits with Mr 40 0...

Purified DNA-dependent RNA polymerase from Sulfolobus acidocaldarius is composed of 10 different subunits, one of which is present as four copies. Their molecular weights are 122 000, 101 000, 44 000, 32 000, 24 000, 17 500, 13 800, 11 800 (four copies), 11 200, 10 800, summing up to a total Mr of 423 500. The sedimentation velocity is 13.5 S, indicating that at 0.5 M NH4Cl the enzyme exists in...

Hepatocellular carcinoma (HCC) is the fifth most common cancer in men and eighth most common cancer in women worldwide, resulting in at least 500 000 deaths per year. It accounts for 90% of all liver cancers. Its crude incidence in the European Union is 8.29/100 000. Areas such as Asia and subSaharan Africa with high rates of infectious hepatitis have incidences as high as 120 cases per 100 000...

background: granuloca cells have a key role during estroeidogenesis. objectives: the purpose of this study was to determine the effect of number of culture medium granulosa cells on estradiol concentrations and mrna codding estrogenic and progestagenic enzyme. methods: briefly, follicles between 2 and 5 mm diameter were dissected from the ovaries of adult cows and were collected by rinsing the ...

INTRODUCTION There is accumulating evidence supporting the use of probiotics, which are defined as "live micro-organisms which, when administered in adequate amounts, confer a health benefit on the host", as a preventive measure against respiratory tract infections (RTI). Two recent meta-analyses showed probiotic consumption (daily intake of 107 to 1010 CFU in any form for up to 3 months) signi...

Stroke has an annual incidence in Britain of about 200 cases for every 100 000 population and a prevalence of about 500 for every 100 000.' Survivors may return to an entirely normal life, but about a third do not achieve functional independence.2 Mood disorder may be a specific complication of stroke,3 and failure to recognise and treat the disorder may be an important unmet need of survivors ...

morbidity and mortality because of its association with coronary heart disease, cerebrovascular disease and renal disease. The extent of target organ involvement (i.e. heart, brain and kidneys) determines outcome. North American studies have shown that hypertension is a major contributor to 500 000 strokes (250 000 deaths) and 1 000 000 myocardial infarctions (500 000 deaths) per annum. Nationa...
