QUESTIONS UNDER STUDY After years of advocating ABC (Airway-Breathing-Circulation), current guidelines of cardiopulmonary resuscitation (CPR) recommend CAB (Circulation-Airway-Breathing). This trial compared ABC with CAB as initial approach to CPR from the arrival of rescuers until the completion of the first resuscitation cycle. METHODS 108 teams, consisting of two physicians each, were rand...

The objective of the present investigation was to design a sustained release floating microcapsules of theophylline using two polymers of different permeability characteristics; Eudragit RL 100 (Eu RL) and cellulose acetate butyrate (CAB) using the oil-in-oil emulsion solvent evaporation method. Polymers were used separately and in combination to prepare different microcapsules. The effect of d...

BACKGROUND Coronary revascularization on the beating heart is an attractive to option conventional coronary artery bypass graft (CABG) but remains controversial. Our study encourages sufficient proper time for decision-making when changing CABG from off-pump to on-pump CABG. We report herein patients who changed from off-pump CABG to on-pump CABG. METHODS A retrospective analysis of 240 patie...

Transcription of Cab genes has been previously shown to be regulated by a circadian oscillator coupled to the red light-absorbing plant photoreceptor phytochrome in various plant species. In addition, it has recently been suggested that rhythmic expression of the Cab genes could also be affected by a phytochrome-independent circadian oscillator in a developmentally regulated fashion. This study...

Background. The cadets experienced particular difficulties in a pandemic period because due to isolation and faced a number of unanticipated challenges like stress, anxiety, and low learning outcomes. Objectives: The aim of the study was to evaluate the effectiveness of sport and traditional games to improve cadets’ learning performance and motivation to learning activities and future service ...

In this paper, I analyze the organization of tasks or activities by a collection of agents. I begin by formally defining organized collections and robustly organized collections of agents in the context of a simple model. Within this framework, I demonstrate that organized collections and robustly organized collections exist and equilibria need not be organized. I then test whether adaptive age...

It is assumed to be common knowledge that multivalent cations cross-link soil organic matter (SOM) molecules via cation bridges (CaB). The concept has not been explicitly demonstrated in solid SOM by targeted experiments, yet. Therefore, the requirements for and characteristics of CaB remain unidentified. In this study, a combined experimental and molecular modeling approach was adopted to inve...

After several cases of occupational asthma had been reported in a coffee processing factory in England, 197 coffee workers representing 80% of the production workforce were studied to determine the factors affecting the development of work related respiratory symptoms of wheeze, cough, and dyspnoea. Two computer administered questionnaires concerning the presence of respiratory symptoms and the...
