We demonstrate the feasibility of strong (up to atomic fields) and supershort (few-femtosecond or even subfemtosecond) subcycle (nonoscillating) electromagnetic solitons [EM bubbles (EMB’s)] in a gas of two-level atoms as well as EMB’s and preionization shock waves in classically nonlinear atoms. We show that EMB’s can be generated by existing sources of radiation, including subpicosecond half-...

PurposeEndomyocardial biopsy (EMB) is considered the gold standard for screening rejection in heart transplant (HT) recipients. Lack of histological evidence on EMB has typically been reassuring to clinicians, but interpretation elevated levels donor-derived cell free DNA (dd-cfDNA) setting a “negative” unclear.MethodsPatients from multi-center Surveillance Using HeartCare Outcomes Registry (SH...

The reliability of the BACTEC MGIT 960 system, an automated version of the Mycobacteria Growth Indicator Tube (MGIT), for antimicrobial susceptibility testing of Mycobacterium tuberculosis was evaluated on 78 clinical isolates. Rifampin (RMP), isoniazid (INH), streptomycin (SM), and ethambutol (EMB) were tested at the following concentrations: 1.0 microg/ml for RMP, 0.1 and 0.4 microg/ml for IN...

The emergence of antibiotic resistance in mycobacteria involves the selection of mutant variants within a susceptible bacterial population. However, it is unclear whether antimycobacterial drugs act just as selective agents or can influence the rate of appearance of resistant mutants. The present study was initiated to address this issue by monitoring the effects of antimicrobial agents on the ...

Graft-infiltrating cells can be cultured from fresh endomyocardial biopsies (EMB) taken after heart transplantation to determine their growth patterns, phenotypic composition, and functional characteristics for clinical or scientific purposes. In this study we investigated whether graft-infiltrating cells can also be cultured successfully after cryopreservation of these EMB. Three different cry...

Introduction: Visual assessment of endomyocardial biopsy (EMB) specimens may result in errors due to the human factor and inability obtain quantitative data on intensity immunohistochemical (IHC) reactions severity pathological changes heart transplant. Detailed digital characterization EMB based automated or semi-automated computer-assisted morphometry improves diagnostic accuracy EMB. Objecti...

A growing interest in Electromechanical Brakes (EMBs) is discernible the automotive industry. Nevertheless, no EMBs have ever been deployed for series production, although countless publications made, and patents filed. One reason this need optimization of functional safety. Due to missing mechanical/hydraulic link between driver actuator, sophisticated concepts be elaborated upon. This paper p...

Abstract A bioanalytical method for simultaneous quantification of isoniazid (INH), pyrazinamide (PZA) and ethambutol (EMB) in plasma was developed validated using high-performance liquid chromatography with tandem mass spectrometry. After extracted by protein precipitation acetonitrile, the analytes were separated on a Waters XBridge Amide column isocratic elution acetonitrile 5 mM ammonium ac...
