The possibility that conditions on the Sun and in the Earth’s magnetosphere can affect human health at the Earth’s surface has been debated for many decades. This work reviews the research undertaken in the field of heliobiology, focusing on the effect of variations of geomagnetic activity on human cardiovascular health. Data from previous research are analysed for their statistical significanc...
The pulsed radio emission from the Galactic Center (GC) magnetar SGR J1745-29 probes the turbulent, magnetized plasma of the GC hyperstrong scattering screen through both angular and temporal broadening. We present the first measurements of the angular size of SGR J1745-29, obtained with the Very Long Baseline Array and the phased Very Large Array at 8.7 and 15.4 GHz. The source sizes are consi...

BACKGROUND In several European countries, centralization of oesophagogastric cancer surgery has been realized and clinical audits initiated. The present study was designed to evaluate differences in resection rates, outcomes and annual hospital volumes between these countries, and to analyse the relationship between hospital volume and outcomes. METHODS National data were obtained from cancer...
Introduction . The study of rheological properties (dynamic and plastic viscosity, yield strength, the degree presence a thixotropic effect, nature type flow) are important for development soft dosage forms. These affect stability form during storage, its technological consumer characteristics Aim Study main parameters developed gels creams on various carrier bases. Materials methods Meloxicam ...
It is now agreed that 10-25% of infertile men with azoospermia have submicroscopic deletions of the Y chromosome long ann (yq), consistent with the proposed location of the azoospermia locus (AZF) in Yq 11.23. However, it is not known whether Yq microdeletions are unique to men with azoospermia or whether they are also observed in infertile men with less severe defects of spermatogenesis (o...
سابقه و هدف: در جنگ ایران و عراق، گازهای شیمیایی توسط عراق به کار گرفته شد. تاثیر گازها در کوتاه مدت و میان مدت قبلا گزارش گردیده بود. با توجه به گزارش های متفاوت از نقش گاز خردل در جانبازان شیمیایی و به منظور پیگیری نقش این گازها بر گویچه های هموگلوبین و شاخص های خونی، این تحقیق بر روی مراجعه کنندگان به بنیاد جانبازان استان گیلان در سال های 77-1376 انجام گرفت. مواد و روش ها: تحقیق به روش هم گر...
پروانه جوانه خوار archips rosanus از آفات پلی فاژ در حال گسترش در باغ های مرکبات غرب استان مازندران می باشد. در این تحقیق اثر باکتری bacillus thuringiensis subsp kurstaki روی مراحل مختلف لاروی کرم جوانه خوار مرکبات archips rosanus مورد بررسی قرار گرفت. برای انجام آزمایش های زیست سنجی در شرایط آزمایشگاهی از روش غوطه ورسازی (dipping method) استفاده شد.lc50 و lc90 باکتری b.t برای لاروهای سن اول و ...
