We propose to estimate time-varying frequency-selective channels using data-dependent superimposed training (DDST) and a basis expansion model (BEM). The superimposed training consists of the sum of a known sequence and a data-dependent sequence, which is unknown to the receiver. The data-dependent sequence cancels the effects of the unknown data on channel estimation. Symbol detection is perfo...

Objectives: Resistance to third generation cephalosporins in E. coli and K. pneumoniae are due to various factors. The present study was undertaken to detect resistance mediated by ESBL’s. Multidrug resistance in isolates producing ESBL was also studied. Methods: The study included a total of 200 clinical specimens which include 95 urine, 45 pus, 32 sputum, 11 blood, 9 throat swabs, 6 suction t...

background: infectious by pseudomonas aeruginosa has spread worldwide and metallo-beta-lactamases (mbl) are being reported with increasing frequency. the aim of this study was to investigate the antibiotic susceptibility and distribution of blavim and blaimp genes in p. aeruginosa isolates from zanjan province of iran. methods: a total of 70 p. aeruginosa isolates were identified from patients ...

Objective: The effects of prenatal coronavirus 2019 disease (COVID-19) exposure on the infantile neurological development are unknown. It has been considered that inflammatory, thrombotic, and vascular changes occurred in placentas taken from pregnant women diagnosed with COVID-19 inflammatory nature infection may lead to negative obstetric events. We aimed assess potential infant.

Abstract Introduction Escherichia coli is an opportunistic bacteria that can grow easily, produce toxins, and resist antibiotics. The phenomenon of E. developing multidrug resistance currently the subject extensive research. objective this study was to molecularly identify bla TEM CTX-M genes in multidrug-resistant found milk samples from dairy cattle farms Tulungagung, Indonesia. Material Meth...

With the occurrence of extended-spectrum beta-lactamases (ESBLs) in Pseudomonas aeruginosa being increasingly reported worldwide, there is a need for a reliable test to detect ESBLs in clinical isolates of P. aeruginosa. In our study, a total of 75 clinical isolates of P. aeruginosa were studied. Nitrocefin tests were performed to detect the beta-lactamase enzyme; isoelectric focusing electroph...

This study was conducted to determine the incidence of Pseudomonas aeruginosa infections among burn patients at Tohid Hospital, Iran. A total of 176 clinical specimens were obtained from 145 burn patients admitted to the burn unit of Tohid Hospital to detect the presence of P. aeruginosa. Antimicrobial susceptibility testing was conducted to detect extended spectrum beta-lactamase (ESBL) produc...

BACKGROUND Pseudomonas aeruginosa is an opportunistic pathogen associated with nosocomial infections. The emergence and dissemination of metallo-beta-lactamases (MBLs) has contributed to the high rate of resistance among P. aeruginosa isolates. OBJECTIVES The purpose of this study was to describe the prevalence and the clonal dissemination of MBL- producing P. aeruginosa isolates collected fr...
