This review focused on the treatment-emergent mania/hypomania (TEM) associated with repetitive transcranial magnetic stimulation (rTMS) treatment of depression. English-language literature published from 1966-2006 and indexed in Medline was searched. Ten of 53 randomized controlled trials on rTMS treatment of depression specifically addressed TEM. The pooled TEM rate is 0.84% for the active tre...
We conducted a prospective multicenter study in Spain to characterize the mechanisms of resistance to amoxicillin-clavulanate (AMC) in Escherichia coli. Up to 44 AMC-resistant E. coli isolates (MIC ≥ 32/16 μg/ml) were collected at each of the seven participant hospitals. Resistance mechanisms were characterized by PCR and sequencing. Molecular epidemiology was studied by pulsed-field gel electr...
Leukocyte transendothelial migration (TEM) is a tightly regulated, multistep process that is critical to the inflammatory response. A transient increase in endothelial cytosolic free calcium ion concentration (↑[Ca(2+)]i) is required for TEM. However, the mechanism by which endothelial ↑[Ca(2+)]i regulates TEM and the channels mediating this ↑[Ca(2+)]i are unknown. Buffering ↑[Ca(2+)]i in endot...
OBJECTIVE Transanal endoscopic microsurgery (TEM) allows locally complete excision of rectal neoplasms and provides an alternative to conventional surgery for benign tumours. However, its role in the curative treatment of invasive carcinoma is controversial. This paper examines the results of TEM compared with radical surgery (RS) for T1 rectal cancer. METHODS 51 patients with T1 rectal tumou...
In situ transmission electron microscopy (TEM) has been extensively applied to study radiation effects in a wide variety of materials, such as metals, ceramics and semiconductors and is an indispensable tool in obtaining a fundamental understanding of energetic beam-matter interactions, damage events, and materials' behavior under intense radiation environments. In this article, in situ TEM obs...
In vivo, leukocyte transendothelial migration (TEM) occurs at endothelial cell junctions (paracellular) and nonjunctional (transcellular) locations, whereas in vitro models report that TEM is mostly paracellular. The mechanisms that control the route of leukocyte TEM remain unknown. Here we tested the hypothesis that elevated intercellular adhesion molecule-1 (ICAM-1) expression regulates the l...
BACKGROUND AND STUDY AIMS Large ( > 2 cm) rectal adenomas are currently treated by either transanal endoscopic microsurgery (TEM) or piecemeal endoscopic mucosal resection (EMR). The potential lower morbidity of EMR may become irrelevant if EMR is less effective. The aim of this study was to compare the safety and effectiveness of EMR and TEM for large rectal adenomas. PATIENTS AND METHODS A ...
TEM images are rapidly gaining prominence in various sectors like life sciences, pathology, medical science, semiconductors, forensics, etc. Hence, there is a critical need to know the effect of existing image restoration and enhancement techniques available for TEM images. This paper primarily focuses on DVROFT filter. After simulation it is observed that the SNR and PSNR ratios obtained for T...
BACKGROUND & OBJECTIVE Extended-spectrum beta-lactamases (ESBLs) are rapidly evolving group of beta-lactamase enzymes produced by the Gram negative bacteria. These enzymes have been derived from TEM and SHV genes by mutations and have been well described in Klebsiella pneumoniae. Information on molecular types of ESBL positive Klebsiella sp. is lacking from India. We therefore undertook this st...
تشبیه در خیال آفرینی و آراستگی متن تاریخ وصّاف نقش مهمی را ایفا می کند. وصّاف الحضره، در این اثر سعی دارد تا با بهره گیری از عناصر بیانی؛ بخصوص تشبیه، منطق نثری این کتاب را به نثر شاعرانه نزدیک تر نماید. نبود نسخه ای منقّح از تاریخ وصّاف و نثر مصنوع و متکلّف آن، همواره موجب گردیده تا این کتاب ارزشمند، کمتر مورد اقبال و بررسی قرار گیرد. این پژوهش برآن است تا ضمن آشنا ساختن مخاطبان با ساختار تشبیه در ...
