BACKGROUND Efficiently performed basic life support (BLS) after cardiac arrest is proven to be effective. However, cardiopulmonary resuscitation (CPR) is strenuous and rescuers' performance declines rapidly over time. Audio-visual feedback devices reporting CPR quality may prevent this decline. We aimed to investigate the effect of various CPR feedback devices on CPR quality. METHODS In this ...

Beta-lactamase enzymes (BLs) have become the most worrisome mediators of antimicrobial resistance expressed by gram-negative bacteria (GNB). The multiple families of BLs have in common the ability to hydrolyze the -lactam rings of one or more members of the penicillins, cephalosporins, cephamycins, carbapenems, and monobactams. Extended-spectrum -lactamases (ESBLs) are a subset of BLs that conf...

Objective The aim of this study was to examine retention of CPR/BLS knowledge of third year nursing and fourth year chiropractic students following instruction and assessment of CPR/BLS skills and knowledge as part of their undergraduate degree program. Design Non‐experimental exploratory survey to determine perceived ability and knowledge of CPR/BLS following completion of CPR/BLS instruction....

background. for several years, educators have criticized the lecture-based approach to teaching and learning. experts have rightly stressed on acquisition of a number of critical skills rather than focusing on lectures. purpose. to compare students’ performance after self-education with vcd and manikin, with thei performance after standard bls training. methods. in this randomized controlled st...

The human immunodeficiency, type II bare lymphocyte syndrome (BLS), has been attributed to a defect in the transcription of class II histocompatibility genes. Immunocompetence, as assessed by functional exogenous antigen presentation, was not restored in immortalized B cells, derived from a BLS patient, after transfection with HLA-DR class II structural genes. Incubation of protein antigens, as...

OBJECTIVES To study the awareness on Basic Life Support (BLS) (CPR) in undergraduate medical students. METHODS A cross sectional studywas conducted by using responses to a questionnaire regarding BLS by 61 students. The results were analyzed with SPSS version 11.101. RESULTS Out of 61 students only 9 (14.7%) had taken a BLS (CPR) course while 52 (85.3%) students had not attended any such co...

In Asiacrypt2001, Boneh, Lynn, and Shacham [8] proposed a short signature scheme (BLS scheme) using bilinear pairing on certain elliptic and hyperelliptic curves. Subsequently numerous cryptographic schemes based on BLS signature scheme were proposed. BLS short signature needs a special hash function [6, 1, 8]. This hash function is probabilistic and generally inefficient. In this paper, we pro...

AIM In order to elucidate the factors for willingness to perform CPR, we evaluated the responses of college students to questionnaires before and after basic life support (BLS) training. METHODS Before and after participating in a small group BLS course, 259 students completed questionnaires. A logistic regression model was used to elucidate independent factors for their willingness to attemp...

Vitreousness and Stenvert kernel hardness characteristics in corn germplasm have been related to in situ and in vivo starch digestibility in lactating dairy cows. Because of the tedious nature of determining vitreousness by manual dissection or conducting Stenvert hardness measurements, it is challenging to screen corn germplasm for animal performance potential. The resistance of corn to grindi...

This study was conducted to evaluate the immunogenicity of the Brucella abortus lumazine synthase (BLS) gene cloned into the pcDNA3 plasmid, which is driven by the cytomegalovirus promoter. Injection of plasmid DNA carrying the BLS gene (pcDNA-BLS) into BALB/c mice elicited both humoral and cellular immune responses. Antibodies to the encoded BLS included immunoglobulin G1 (IgG1) IgG2a, IgG2b, ...
