In view of the rising prevalence of dengue virus and mixing of host and vector populations, complete full-length sequence determination of dengue strains isolated from different epidemic areas is important for the study of virus evolution, pathogenicity, vaccine efficiency and diagnosis. Based on the genomic analysis of 51 complete dengue virus sequences, all of which cocirculated in Thailand b...
AIM To compare experience of positive blood cultures in successive years before and after changing from Signal (Unipath) to Bactec 9240 (Becton Dickinson) blood culture systems. METHODS Analysis of data collected prospectively on 7967 Signal and 7062 Bactec blood culture sets. RESULTS Significant growths occurred in 5.7% of Signal and 8.9% of Bactec cultures; 33.0% more significant isolates...
The relatively simple Ohta-Kawasaki density functional theory for diblock copolymer melts allows us to construct and analyze exact solutions to the EulerLagrange equation by singular perturbation techniques. First we consider a solution of a single sphere pattern that models a cell in the spherical morphology. We show the existence of the sphere pattern and find a stability threshold, so that i...

گلومالین یک ترکیب گلیکوپروتئینی ویژه است که توسط قارچهای راسته گلومرال از رده گلومرومایکوتا تولید میشود. با توجه به همزیستی گسترده این قارچها با تعداد زیادی از گیاهان، سالانه مقادیر قابل توجهی از گلومالین توسط این قارچها وارد اکوسیستم خاک میشود. شواهد موجود نشان میدهند که این مادّه گاهی به تنهایی یک سوم از کل کربن آلی خاک را به خود اختصاص میدهد. بنابراین نقش کلیدی در ذخیره کربن آلی خاک دارد. همچ...
در این پژوهش، آثار افزودن کی لیت طبیعی اسید سیتریک و کی لیت های مصنوعی hedta و egta در محلول کردن کادمیوم در خاک هایی که به طور مصنوعی آلوده شده اند و نیز توانایی آنها در افزایش پالایش گیاهی کادمیوم توسط گیاه تربچه (raphanus sativus l.) از خانواده (brassicaceae) با یکدیگر مقایسه و بررسی شد. این آزمایش با استفاده از یک طرح فاکتوریل در قالب بلوک های کامل تصادفی در سه تکرار انجام شد. تیمارهای غلظت...
