Introduction: In this study, Zn3(Btc)2 (metal organic framework) sorbent was introduced for sampling of Benzo[a]pyren from the air. The purpose of this study was to develop the sampling and analysis method by needle trap, with no sample preparation step. Material and method: Zn3(Btc)2 sorbent was electrochemically synthesized and its properties were specified by FTIR, FE-SEM, and PXRD techniqu...
PURPOSE This study proposes an alternative preparation method of platelet-rich plasma (PRP). Specifically, we compare the use of thrombin receptor agonist peptide-6 (TRAP) and bovine thrombin as a clotting agent in the preparation of PRP. MATERIALS AND METHODS PRP was prepared by centrifugation and clotted with thrombin or TRAP. In vitro clotting times were monitored as a function of TRAP con...
مقدمه: زعفران به عنوان یک دارو از دیرباز مورد توجه بوده است و گزارشهایی از اثرات ضد سرطانی کروسین ، رنگدانه اصلی زعفران وجود دارد. از آنجا که نامیرایی سلولهای سرطانی عمدتاً ناشی از فعال شدن آنزیمی به نام تلومراز است، تأثیر کروسین بر فعالیت این آنزیم در سلولهای آدنوکارسینومای سینه رده MCF7 مورد بررسی قرار گرفت.مواد و روش ها: غلظت IC50 کروسین پس از 48 ساعت تیمار سلولها با استفاده از روش MTT تخم...
Beams of neutral polar molecules in a low-field seeking quantum state can be slowed down using a Stark decelerator, and can subsequently be loaded and confined in electrostatic quadrupole traps. The efficiency of the trap loading process is determined by the ability to couple the decelerated packet of molecules into the trap without loss of molecules and without heating. We discuss the inherent...
Two types of mosquito trap were tested near Smith Lake in Portland, Multnomah County, OR: 2 Biogents Sentinel (BGS) traps baited with carbon dioxide (CO2) and an octenol sachet or a BG Lure, and an encephalitis virus surveillance (EVS) trap with CO2 but without an odor sachet. After 6 trap-nights, the 2 BGS traps caught significantly more mosquitoes than the EVS trap. More Culex tarsalis and an...
سرمایش لیزری (laser cooling) روش است که توسط نور لیزر میتوان حرکت اتمها را کند کرد و دمای آنها را تا حد میکروکلوین پایین آورد. در این دما سرعت اتمها بسیار کند شده و میتوان تک تک اتمها را با دقت زیادی مطالعه کرد و ساختار داخلی آنها را مشخص کرد. از کاربردهای سرمایش لیزری میتوان، طراحی ساعتهای اتمی دقیقتر، تداخل سنجهای اتمی، جدا کردن ایزوتوپها، کشف ماده چگال بوز-انیشتین در گازهای اتمی و ساخت لیزره...
Even if the transition is made from a middle-income country to a high-income country due to high growth in a short period of time like in the NIEs, there is the possibility that after the middle-income trap, there is another waiting trap of a sort faced by high-income countries. Even in the case that some time is needed for growth and the middle-income trap is experienced, it is possible duri...
Several trap designs have been used for sampling and control of the tsetse fly, Glossina fuscipes fuscipes, Newstead (Diptera: Glossinidae) based on preferences of individual researchers and program managers with little understanding of the comparative efficiency and cost-effectiveness of trap designs. This study was carried out to evaluate the cost-effectiveness of four commonly used trap desi...
