Abstract Background: Hirsutism is a common symptom presenting to primary care endocrinologists, gynecologists, and dermatologists. Management is usually a long and troublesome process. This study was designed to evaluate the effect of fennel topical gel on mild to moderate idiopathic hirsutism. Methods: The randomized, double-blind, placebo-controlled clinical trial was carried out from 2009 ...
Objective: Cassia fistula L. fruit extract has been traditionally used in the treatment of pemphigus vulgaris (PV) lesions in Iran. The aim of this study was to determine the efficacy of C. fistula fruit gel on healing time of PV lesions in a clinical setting.Materials and Methods: This was a randomized, double-blind placebo-controlled clinical trial that was performed in dermatology ward at Sa...
While many forms of memory management have been proposed, the only ones to achieve widespread adoption have been explicit deallocation and garbage collection. This leaves programmers requiring explicit control of memory behavior unable to obtain the software engineering and security benefits of programming in a safe language. We present a new approach to memory management called alias counting ...
Objective: Tooth surface undergoes continuous remineralization and demineralization. The aim of this study was to compare the effect of Caseinphosphopeptide-amorphous calcium phosphate (CPP-ACP) paste and Fluoride gel on the microhardness of demineralized enamel lesions. Methods: Frothy eight specimens of premolar teeth were chosen and randomly divided to 4 groups of 12. After the initial m...
Background: Our aim was to provide scientific evidence studying the effect of Teucrium polium plus Aloe vera gel on episiotomy wound healing, pain intensity and patient’s satisfaction in primiparous women compared to placebo. Methods: This study is single blind randomized clinical trial that performed on 100 participants. Teucrium polium plus Aloe vera or placebo gel were administered twice on...
the present study deals with development of a floating in-situ gel of the narrow absorption window drug baclofen. sodium alginate-based in-situ gelling systems were prepared by dissolving various concentrations of sodium alginate in deionized water, to which varying concentrations of drug and calcium bicarbonate were added. fourier transform infrared spectroscopy (ftir) and differential scannin...
در این پایان نامه ابتدا نانو ذرات دی اکسید تیتانیم یا تیتانیا به روش شیمیایی sol-gel در دو فاز آناتاز و روتایل سنتز شده است. سپس این نانو ذرات به کمک الگوهای پراش اشعه x (xrd) طیف سنجی uv-vis و میکروسکوب الکترونی رویشی (sem) مشخصه یابی شده است. الگوی پراش اشعه x و تصاویر sem تشکیل ساختارهای نانومتری دی اکسکیدتیتانیم تهیه شده و به روش sol-gel را تایید می کنند ساختار و میانگین اندازه نانو ذرات به...
چکیده: یک الکترود خمیرکربن اصلاح شده با مخلوط ناترولیت آهن دار(fe3+n) و ژل نانو تیوب کربن چند دیواره (mwcnt)- مایع یونی در دمای اتاق (3- هیدروکسی پروپیل آمونیوم استات، hpaa) ساخته شد و ویژگی-های آن به وسیله میکروسکوپ الکترونی عبوری و ولتامتری پالس تفاضلی بررسی شد. مخلوط fe3+n hpaa-mwcnt gel- هدایت، پایداری و استخراج خوبی را نشان داد که به علت فعالیت مشترک hpaa, mwcnt و fe3+n می باشد. بعلاوه، ا...
We have developed an optical chamber for studying the effect of swelling or shrinking of a gel on the translational diffusion of fluorescent nanoprobes embedded in the gel. On one side of the chamber, the gel is in contact with a hydrating or dehydrating polymeric solution through a porous membrane, allowing control of the rate of hydration or dehydration of the gel. On the other side, a laser ...
