conclusions physical or physiological and psychological stressors impose greater stress and are predictors of anxiety. when preparing their nursing care plan, nurses should consider these stressors that affect anxiety levels in patients undergoing cabg surgery and those hospitalized in intensive care units. patients and methods this is a descriptive-analytical study that uses a non-random conve...

introduction: pain management after coronary artery bypass graft surgery (cabg) is an ‎important nursing care which can result in faster recovery and patient satisfaction.‎ objective: the aim of study was to determine post cabg patients’ perception on pain management ‎quality.‎ methods: this cross-sectional study was conducted on ‎‏108‏‎ cabg patients, who were chosen by ‎sequential sampling me...

aim and background: coronary artery bypass graft (cabg) surgery is the most common surgical procedure for patients suffering from coronary artery diseases. many studies demonstrated cabg as a serious crisis for patients resulting in excessive stress and anxiety. this study was performed to assess the effects of reflexology on anxiety levels among cabg surgery candidates in shahid chamran hospit...

a 47 year-old female died after mitral valve replacement. post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. at microscopic examination, diffuse right ventricular fatty infiltration was found. we found no previous report of this pathology in patients with mitral stenosis

We demonstrate that exciton conductance in organic materials can be enhanced by several orders of magnitude when the molecules are strongly coupled to an electromagnetic mode. Using a 1D model system, we show how the formation of a collective polaritonic mode allows excitons to bypass the disordered array of molecules and jump directly from one end of the structure to the other. This finding co...

The CFTR chloride channel is activated by phosphorylation of serine residues in the regulatory (R) domain and then gated by ATP binding and hydrolysis at the nucleotide binding domains (NBDs). Studies of the ATP-dependent gating process in excised inside-out patches are very often hampered by channel rundown partly caused by membrane-associated phosphatases. Since the severed DeltaR-CFTR, whose...

an experiment was conducted in early lactating buffaloes for the period of 3 months in jadakheria and polisimal village of limkhedataluka in dahod district of gujarat to assess the effect of supplementation of bypass fat on milk production, composition, body weight change and economic efficiency. forty buffaloes in their 2nd and 3rd lactation were equally divided in completely randomized design...

In this study, involvement ofvoltage-dependent calcium channels in LTP of responses of rat visual cortex slices was analyzed. Field potentials including EPSP1 and EPSP2 from layers II/III were recorded through stimulation of layer IV. Whereas nifedipine, a L-type calcium channel blocker (L-VDCC), did not considerably affect the LTP of responses, but Ni2+, a relatively selective blocker of T-typ...

conclusions the findings showed a positive effect of therapeutic relationship based on peplau's model on reducing anxiety of patients undergoing cabg. therefore, health care teams, including nurses, should take advantage of appropriate communication with patients in their care procedures. in that regard, peplau's communication model is recommended as a simple, low-cost, and efficient method. re...

background according to the previous studies, antihypertensive drugs should be withdrawn before surgery. nowadays it is accepted that some drugs effectively control systemic blood pressure (bp) to assure its desirable therapeutic control. objectives in this study, the effects of captopril, an angiotensin converting enzyme inhibitor (acei), on hemodynamic changes before, during and after the cor...
