Ceftazidime-resistant isolates of Escherichia coli and Klebsiella pneumoniae produced a plasmid-mediated beta-lactamase with a pI of 5.6 with biochemical characteristics comparable to those of the TEM-10 beta-lactamase. Plasmids from the two strains were nonidentical. Both TEM-10 sequences differed from TEM-1 by substitutions of Ser-162 and Lys-237. The nucleotide sequences of the two genes wer...
Recent major improvements to the transmission electron microscope (TEM) including aberration-corrected electron optics, light-element-sensitive analytical instrumentation, sample environmental control, and high-speed and sensitive direct electron detectors are becoming more widely available. When these advances are combined with in situ TEM tools, such as multimodal testing based on microelectr...
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...
In experimental mouse models of cancer, increasingly compelling evidence point toward a contribution of tumor associated macrophages (TAM) to tumor lymphangiogenesis. Corresponding experimental observations in human cancer remain scarce although lymphatic metastasis is widely recognized as a predominant route for tumor spread. We previously showed that, in malignant tumors of untreated breast c...
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...
مد لباس کالای کاربردی نیست چون علاوه بر ارزش اقتصادی واجد ارزش فرهنگی نیز هست و از این رو تقاضای آن متفاوت از کالاهای مرسوم است. این تحقیق به دنبال شناسایی عوامل موثر بر تقاضای مد لباس ایرانی بوده است. بررسی ها نشان می دهند که عوامل اقتصادی، عوامل فرهنگی و عوامل سمت عرضه در تقاضای مد لباس موثر هستند. عوامل شناسایی شده، از طریق پرسشنامه و مصاحبه در رابطه با زنان متقاضی مد در شهر اصفهان مورد آزمو...
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...
