The methanol extract of Mimosa pudica was studied for its antibacterial activity against twelve pathogenic bacteria. also effect on acetic acid induced writhing model in mice. showed good two gram-positive and six gram-negative bacteria but failed to show any Staphylococcus pyogenes, Salmonella typhi, Shigella boydii Vibrio cholera. exhibited no antinociceptive test; rather it increased the abd...

به علت تغییرات حجم ناشی از خطای ساخت، فرکانس کاواک‌های شتاب‌دهی در شتاب‌دهنده‌های خطی الکترون تغییر می‌کند. نتیجه تنظیم فرکانسی کاواک‌ها یکی مراحل مهم تست سرد است که باید الزامات آن طراحی لحاظ شود. پروژه ساخت ساختار موج‌ایستا برای شتاب­دهنده با دو انرژی، پس طراحی، یک آلومینیمی (شامل نیم کاواک و تزویج) ساخته شد. این جبران پیچ‌های استفاده پیچ‌ها جزیی کاواک‌ها، آن‌ها را می‌دهند. مقاله محاسبات شبیه...

OBJECTIVE The present study was undertaken to evaluate the antinociceptive effects of an ayurvedic polyherbal formulation in rats and mice employing the tail immersion test and acetic acid-induced writhing test, respectively. MATERIALS AND METHODS With the tail immersion method, rats received two different doses (270 and 405 mg/kg BW, p.o.) of a formulation, pethidine (5.4 mg/kg BW, p.o.) as ...

Introduction: the methanolic extracts and its different partitioning fractions of leaves of Clerodendrum indicum were evaluated for their anti-nociceptive, anti-diarrheal and in vitro antimicrobial activities. Methods: the anti-nociceptive activity was evaluated using the acetic acid-induced writhing test in mice; the anti-diarrheal activity was investigated by the effect of extracts on castor ...

The study has evaluated the effect of diabetes associated hyperglycaemia on nociception and antinociception induced by morphine, buprenorphine and pentazocine in female albino rats. Rats were allocated into 3 groups of 20 each--group I consisted of control having normal blood glucose levels (BGLs), group II consisted of streptozotocin-induced diabetics (STZ-D) having hyperglycaemia and group II...

We find bounds on the difference between the writhing numbers of a smooth curve and a polygonal curve inscribed within. The proof is based on an extension of Fuller’s difference of writhe formula to the case of polygonal curves. The results establish error bounds useful in the numerical computation of writhe.

In considering supercoils formed by closed double-stranded molecules of DNA certain mathematical concepts, such as the linking number and the twist, are needed. The meaning of these for a closed ribbon is explained and also that of the writhing number of a closed curve. Some simple examples are given, some of which may be relevant to the structure of chromatin.
