G iven the high prevalence of coronary artery disease in Western countries, selection of the optimal therapeutic strategy for individual cardiac patients has become an issue of utmost costbenefit importance. During the past two decades, large clinical trials have established the respective roles of medical treatment versus coronary artery bypass surgery in the management of patients with corona...

susceptibility tests were carried out on anopheles stephensi with d.d.t(4%), dieldrin (4%), malathion(5%), propoxus (0.1%), primphos-methyl (o.lmg/cm2), lambda-cyhalothrin (0.1%), permethrin (0.25%) and deltamethrin (0.025%) during 1990-94 in minab county, soutern iran, using w.h.o standard method. results showed that an. stephensi was susceptible to malathion, propoxur, primphos - methyl, lamb...

background diarrhea is the most frequent health problem among children in developing countries. defining the etiology of acute diarrhea is critical to disease therapy and prevention. some anaerobic bacteria such as enterotoxigenic bacteroides fragilis (etbf) strains cause diarrheal disease by production of enterotoxin in children less than 5 years old. objectives this study aimed to evaluate th...

To investigate the genetics of susceptibility to early onset pauciarticular juvenile chronic arthritis (JCA), 158 unrelated ethnic British patients with a mean disease onset of 3.2 years, together with controls, were tested for HLA-A, B, C, and DR antigens. Additionally, 117 patients were also investigated for complement Bf and C4 markers. New observations included an increased frequency of the...

We have designed, fabricated and tested a real-time PCR chip capable of conducting one thermal cycle in 8.5 s. This corresponds to 40 cycles of PCR in 5 min and 40 s. The PCR system was made of silicon micromachined into the shape of a cantilever terminated with a disc. The thin film heater and a temperature sensor were placed on the disc perimeter. Due to the system's thermal constant of 0.27 ...

The mean incidence of colorectal carcinoma in persons under age 40 in Sweden is 1.74/100,000/year. Over a 30-year period, 1950 through 1979, 1061 patients with colorectal carcinoma were seen, 48 of whom where under age 40 (21 to 39 years) and in this study were compared with older patients. Carcinoma was superimposed upon ulcerative colitis in 18 patients. All patients treated for palliation di...

AIM To determine whether measurement of serum troponin T concentration after first acute myocardial infarction can be used to identify patients with a left ventricular ejection fraction of < 40%, who have an adverse prognosis. METHODS Troponin T concentration was measured, and coronary and left ventriculography performed in 50 consecutive patients with acute myocardial infarction. Angiographi...
