We identified individuals whose serum contained a substance that produced falsely decreased thyroid hormone (T)-uptake values determined by the Emit (Syva) procedure. Investigation of this interference was prompted by identification of a patient with T-uptake values inconsistent with clinical assessment. IgG depletion and supplementation studies with this patient's serum suggested that the inte...
Diagnostic approaches to onychomycosis have traditionally been based on a combination of culture and microscopy. In the present study clinical specimens from 346 patients with suspected onychomycosis were analysed by 18S polymerase chain reaction (detection) followed by sequencing and subsequent database search (identification) in parallel with routine culture on agar (detection and identificat...
در جهان امروز و در شرایط رقابتی بازار، کیفیت محصول و بهره وری به عنوان دو عامل اساسی و مهم در حفظ و بقای موسسات حرف اول را زده و آنهایی که از بهره وری و کیفیت بالاتری برخوردار هستند در بازار حضور داشته و ماندگار خواهند ماند. از این رو اطلاع مداوم از وضعیت بازار و کیفیت و کمیت محصولات رقبا و همچنین سیستم ها و روش های انجام کار آنها برای هر موسسه و شرکت رقیب ضروری و اجتناب ناپذیر است تا ضمن اینکه...
In recent clinical trials in patients with metastatic melanoma, adoptive transfer of tumor-reactive lymphocytes mediated the regression of metastatic tumor deposits. To better understand the role of individual T cell clones in mediating tumor regression, a 5' RACE technique was used to determine the distribution of TCR beta-chain V region sequences expressed in the transferred cells as well as ...
BACKGROUND Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, an intracellular protozoan parasite able to infect a wide range of hosts, including humans. Congenital infection can cause severe damage to the fetus. Thus, it is important to detect antibodies against the parasite to confirm clinical manifestations. Considering that all immunoglobulin isotypes may be present in biological samp...
Although admittedly transmission of Trypanosoma cruzi infection through breastfeeding is a rare event, it involves serious risks. To test the effectiveness of pasteurization in preventing this mode of infection, three sets of samples of human milk were tested: a - contaminated with T. cruzi and pasteurized; b - contaminated with T. cruzi and non-pasteurized; c - non-contaminated and pasteurized...
