The operation of belt grinding machines is usually accompanied by a significant level noise and vibration, which adversely affect the health operators accuracy processing final product. It known that in woodworking industry there an increased risk myocardial infarction due to workplace. purpose article theoretical analysis occurrence vibrations construction appropriate mathematical models. infl...
what is engineering and who is an engineer that changed our world so drastically? based on what type of education the engineers have gained the power to do this? what should we do for becoming successful in our professional career? engineers receive competencies in one of the engineering branches during their school years but less effort is made to answer the above questions. in other word, uni...
Objectives: Awareness of elderly patients' experiences of myocardial infarction can assist to identify their need, problems, as well as promote their quality of lives. However, there is a little information about how elderly people experience myocardial infarction. This study aimed to explore elderly patients experience with myocardial infarction and their coping strategies. Methods & Materi...
Background & Aim: Lack of knowledge about acute myocardial infarction and its treatment result in feeling anxious among the patients. Implementing appropriate educational methods can decrease anxiety in patients with acute myocardial infarction. This study was conducted to compare effects of two educational methods (face-to-face and electronic educational methods) on anxiety among patients wi...
Cardiac tissue engineering using biomaterials with or without combination of stem cell therapy offers a new option for repairing infarcted heart. However, the bioactivity of biomaterials remains to be optimized because currently available biomaterials do not mimic the biochemical components as well as the structural properties of native myocardial extracellular matrix. Here we hypothesized that...
BACKGROUND Vein graft failure (VGF) is common after coronary artery bypass graft surgery, but its relationship with long-term clinical outcomes is unknown. In this retrospective analysis, we examined the relationship between VGF, assessed by coronary angiography 12 to 18 months after coronary artery bypass graft surgery, and subsequent clinical outcomes. METHODS AND RESULTS Using the Project ...
High-purity cardiomyocytes (CMs) derived from human induced pluripotent stem cells (hiPSCs) are promising for drug development and myocardial regeneration. However, most hiPSC-derived CMs morphologically and functionally resemble immature rather than adult CMs, which could hamper their application. Here, we obtained high-quality cardiac tissue-like constructs (CTLCs) by cultivating hiPSC-CMs on...
Background—Vasculogenic cell-based therapy combined with tissue engineering is a promising revascularization approach destined at patients with advanced coronary artery disease, many of whom exhibit myocardial hibernation. However, so far no experimental data have been available in this context; we therefore examined the biopolymer-supported delivery of circulating angiogenic cells (CACs) using...
Objective: Embryonic stem cell-derived cardiomyocytes are a useful source for cell transplantation into the heart, as well as for tissue engineering of the extracardiac vascular system. The present study was designed to investigate the survival and contractile function of embryonic stem cell-derived cardiomyocytes around large blood vessels to assess the feasibility of their ectopic use for fut...
myocardial performance, utilizing the isolated canine heart preparation, was studied in two groups: normal control dogs and those subjected to hemorrhagic shock. a marked deterioration in myocardial functional capacity was observed in the shock group. from this study, myocardial incapacity resulting from the period of acute hypotension is felt to be a contributing factor in the death of animals...
