The purpose of this study was to identify factors associated with relapses or re-infections in patients with recurring Clostridium difficile infections (CDIs). From September 2008 to January 2012, cases with two or more isolates from consecutive CDI episodes were included. PCR-ribotyping and multilocus variable-number tandem-repeat analysis were performed using paired isolates. Among 473 patien...
Greece, a malaria-free country since 1974, has experienced re-emergence of Plasmodium vivax autochthonous malaria cases in some agriculture areas over the last three years. In early 2012, an integrated control programme (MALWEST Project) was launched in order to prevent re-establishment of the disease. In the context of this project, the rapid diagnostic tests (RDT) of SD Bioline Malaria Ag Pf/...
Background: Taqman one-step real-time PCR (RT-PCR) has special importance due to its high sensitivity and specificity in the diagnosis of infectious diseases such as viral infections. In recent pandemic SARS-CoV-2, diagnostic kits based on this method are commonly used for molecular detection. One main systematic errors that misinterpret results is using inaccurate internal control RT-PCR kits....
مقدمه: بیماری های قلبی آترواسکلروزیس نشات گرفته از آترواسکلروزیس، مهم ترین عامل مرگ و و میر در بیشتر کشورهاست. انتقال دهنده abcg1 مسئول ساخت و فرم دهی ذرات hdl بوده و به همین دلیل احتمالاً در جلوگیری از گسترش آترواسکلروزیسآتروسکلروزیس نقش دارد. هدف از این مطالعه بررسی تاثیر دو نوع تمرین تک جلسه ای(مقاومتی و استقامتی) بر بیان ژن abcg1 سلول های pbmn بود. روش بررسی: 24 نفر از بین بانوان ورزشکار خرا...
Approximately one-third of breast cancers lack estrogen receptor α (ERα) because of the hypermethylation of the CpG island in the receptor's promoter. These tumors are associated with poorer histological differentiation, a higher growth fraction, are rarely responsive to endocrine therapy and have a worse clinical outcome. Thus, re-expression of ERα in ERα-negative breast cancers may restore th...
thinking simultaneously of humor and battlefield is hardly expectable; however, the most genuine jokes can be seen in this very battlefield verbal culture in a simple and sensitive form which has rarely been paid attention to. this witticism can be categorized into four classes; namely, devotional, fight and martyrdom, drinking and eating, and social interactions which have the most similitude ...
Differential display (DD) is a powerful molecular tool that allows the identification and subsequent isolation of transcripts differentially expressed between biological samples, for example, between undifferentiated and differentiated cells, between different tissues or in one tissue at different stages of development. However, significantly high rates of apparent false positives have been rep...
Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...
OBJECTIVE To determine if Mycobacterium tuberculosis can be detected in corneas of donors who have active tuberculosis (TB) disease using polymerase chain reaction (PCR) or culture. DESIGN This is a prospective cross-sectional study. PARTICIPANTS 25 corneas (12 from TB-negative donors and 13 from TB-positive donors) from the Sta. Lucia International Eye Bank were submitted to the TB Researc...
