زمینۀ مطالعه: تیلریوز گوسفندی یک بیماری تک‌یاخته‌ای مهم در گوسفند و بزها در مناطق گرمسیری و نیمه گرمسیری می‌باشد که باعث ضرر اقتصادی فراوانی در صنعت دام‌پروری می‌شود. هدف: هدف از این مطالعه، تشخیص تفریقی گونه‌های تیلریا در گوسفند با استفاده از روش PCR بود. روش‌کار: تعداد 200 نمونه خون گوسفند جهت تشخیص و تفریق گونه‌های تیلریا مورد بررسی قرار گرفتند. از نمونه‌های خون، استخراج DNA انجا...
The Chinese national observational cohort study suggests that the treatment-as-prevention (TasP) approach can be an effective public health HIV-1 prevention strategy. However, results from that study may have been biased because the follow-up time of index patients prior to their initiation of antiretroviral therapy (ART) was excluded. In this study, we correct for such bias by using an extende...
The history of pre-exposure prophylaxis (PrEP) is notable for being a community rather than industry-driven development. This talk will review this history, covering factors that include community demand, study results, regulatory challenges, commercial interests and practical issues of public health. It will also look at some of the controversies that appear to limit broader access, and import...
Potent antiretroviral therapy (ART) reduces mortality and morbidity in people living with HIV by reducing viral load and allowing their immune systems to recover. The reduction in viral load soon after starting ART has led to the hypothesis that early and widespread ART could prevent onward transmission and therefore eliminate the HIV epidemic in the long term. While several authors have argued...
We report experiments designed to test between Nash equilibria that are stable and unstable under learning. The “TASP” (Time Average of the Shapley Polygon) gives a precise prediction about what happens when there is divergence from equilibrium under fictitious play like learning processes. We use two 4 x 4 games each with a unique mixed Nash equilibrium; one is stable and one is unstable under...
Mathematical models and recent data from ecological, observational, and experimental studies show that antiretroviral therapy (ART) is effective for both treatment and prevention of HIV, validating the treatment as prevention (TasP) approach. Data from a variety of settings, including resource-rich and -limited sites, show that patient attrition occurs at each stage of the human immunodeficienc...
خلاصهتیلریا آنولاتا عامل تیلریوز در گاو از طریق کنه از حیوان آلوده به حیوان دیگر منتقل شده و سالانه خسارات اقتصادی زیادی را در صنعت دامداری وارد می‌سازد. در حال حاضر تنها راه پیشگیری این بیماری استفاده از واکسن تخفیف حدت یافته سلول‌های آلوده به ماکروشیزونت می‌باشد. بسیاری از محققین بدنبال دستیابی به واکسن نوترکیب می‌باشند که به علت سهولت در کاربرد و عدم ایجاد آلودگی، از مزیت بالاتری نسبت به وا...
INTRODUCTION Recently, there has been increasing interest in the role of "treatment as prevention" (TasP). Some of the questions regarding TasP strategies arise from the perceived difficulties in achieving and maintaining viral load (VL) suppression over time and the risk of emergence of viral resistance that could compromise future treatment options. This study was conducted to assess these qu...
INTRODUCTION Scientific evidence supports the synergy between biomedical and behavioral interventions aimed at preventing the transmission of HIV as a strategy to eradicate AIDS. OBJECTIVE To characterize comparatively the benefits from biomedical and behavioral interventions to prevent HIV transmission. METHODS Narrative review. We performed a comparative analysis of the benefits of studie...
