This pilot study was conducted to investigate whether multiple electrophysiological activities could be altered when exposed to extremely low frequency pulsed electromagnetic field (PEMF) over a consecutive 5 day period. Our results revealed substantial changes in electroencephalographic hemispheric asymmetry, observed at the theta band posterior predominance, an increase in the low frequency h...

OBJECTIVES Bronchoscopic microsampling (BMS) is a new technique for repeated sampling of bronchial epithelial lining fluid (ELF) to obtain the pharmacokinetic profile of drugs. We analyzed the time versus concentration profiles of telithromycin in bronchial ELF obtained by BMS and compared these finding to those in plasma and alveolar ELF obtained by bronchoalveolar lavage (BAL). METHODS Bron...

Although transforming growth factor-beta (TGF-beta) is both a suppressor and promoter of tumorigenesis, its contribution to early tumor suppression and staging remains largely unknown. In search of the mechanism of early tumor suppression, we identified the adaptor protein ELF, a beta-spectrin from stem/progenitor cells committed to foregut lineage. ELF activates and modulates Smad4 activation ...

Bronchoalveolar lavage is a powerful technique for sampling the epithelial lining fluid (ELF) of the lower respiratory tract but also results in a significant dilution of that fluid. To quantify the apparent volume of ELF obtained by bronchoalveolar lavage, urea was used as an endogenous marker of ELF dilution. Since urea diffuses readily through the body, plasma and in situ ELF urea concentrat...

The electron localization function (ELF) has been proven so far a valuable tool to determine the location of electron pairs. Because of that, the ELF has been widely used to understand the nature of the chemical bonding and to discuss the mechanism of chemical reactions. Up to now, most applications of the ELF have been performed with monodeterminantal methods and only few attempts to calculate...

We used in vitro translation and antibodies against phosphoserine and the eukaryotic initiation factors elF-4E, elF-4G, and elF-2 alpha to examine the effects of global brain ischemia and reperfusion on translation initiation and its regulation in a rat model of 10 min of cardiac arrest followed by resuscitation and 90 min of reperfusion. Translation reactions were performed on postmitochondria...

Adenosine receptors (ARs) have an important role in the regulation of inflammation and their activation is involved in the inhibition of pro-inflammatory cytokine release. The effects of pulsed electromagnetic fields (PEMFs) on inflammation have been reported and we have demonstrated that PEMFs increased A2A and A3AR density and functionality in different cell lines. Chondrocytes and osteoblast...

OBJECTIVE In the present study, a new healing cap that could generate a pulsed electromagnetic field (PEMF) around titanium implants to stimulate peri-implant osteogenesis was tested in the rabbit model. MATERIALS AND METHODS A total of 22 implants were inserted in the proximal tibial metaphysis of 22 rabbits. A healing cap containing the active device was inserted in half of the implants (11...

AbstractThe last thirty five years have created a challenging situation for Iran and its people: on the one hand, the discriminatory British and American policies towards the country have given rise to considerable bitterness; on the other, we continue to teach both British and American English. If Iranian people wish to play a more active role internationally, it is time to review our English ...

BACKGROUND KL-6 is a mucin-like glycoprotein expressed on the surface of alveolar type II cells. Elevated concentrations of KL-6 in serum and epithelial lining fluid (ELF) in patients with acute respiratory distress syndrome (ARDS) have been previously reported; however, kinetics and prognostic significance of KL-6 have not been extensively studied. This study was conducted to clarify these poi...
