our primary objective was to measure root canal penetrations of aqueous antibacterial nano-chitosan (nano-cs), for the first time. the second objective was to compare and contrast such penetrations to those of chitosan (cs) itself, as well as sodium hypochlorite (naocl), chlorhexidine (chx) and ethylenediamintetraacetic acid (edta), at the routinely used concentrations. molar roots were split l...
background: around one out of two mothers give births by cesarean section (cs) surgery in iran and about half of this number is due to previous cs. recently health sector evolution (hsep) program (started in april 2014) targets the high rate of cs in iran. to assess the impact of the interventions, we emphasized that the first birth cesarean (fbc) proportion is one of the main indicators to ass...
A diacid monomer was synthesized by the condensation of L-tryptophan amino acid and pyromellitic dianhydride (PMDA). The diacid was utilized for the synthesis of three types of poly(amide-imide)s (PAIs) using three different kinds of diamines. The synthesized monomer and PAIs were characterized using FT-IR, 1H-NMR and 13C-NMR spectroscopies and the PAIs were also used ...
در سال های اخیر توموگرافی امپدانس الکتریکی(eit) به دلیل سرعت بالا و غیر مخرب بودن فرآیند نمونه برداری و همچنین کم هزینه بودن تولید سخت افزار در آن مورد توجه بسیاری از تحقیقات، قرار گرفته است و موجب پیشرفت های قابل توجهی در زمینه های پزشکی و صنعتی گردیده است. تصاویری که در eit مورد مطالعه قرار می گیرند تا حدودی اسپارس هستند؛ وجود این ویژگی امکان استفاده از قابلیت های روش سنجش فشرده(cs) در eit را...
A 42-day study was conducted to evaluate the influence of full-fat flaxseed (FS) and canola seed (CS) on broiler performance, fatty acid (FA) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (SRBC). A total of 324 one-day-old chicks were attributed to 6 experimental groups. C: control (soybean-corn); CS1:7.5% CS; CS2:15% CS; CS-FS:10% FS + 10% CS; FS1:...
Cesium radioactive isotopes (134Cs and 137Cs) are dangerous to human health due to their long half-life and high solubility in water. Nuclear experiments, wars, and nuclear plant accidents have been the main sources of Cs release into the environment. In recent years, several methods have been introduced for the elimination of Cs radioactive isotopes from contaminated wate...
background & aim: cesarean section (cs) rates have been increasing steadily, worldwide. the knowledge and attitude of health professionals towards natural childbirth and cs are important factors in selecting a mode of delivery. the purpose of this study was to determine the knowledge and attitude of midwifery and nursing students towards different modes of delivery. methods:in this descriptive,...
