The thermal unimolecular dissociation of CH3F was studied in shock waves by monitoring the UV absorption of a dissociation product identified as CH2F. It is concluded that, under conditions applied, the formation of this species corresponds to a minor, spin-allowed, dissociation channel of about 3% yield. Near to the low-pressure limit of the reaction, on the other hand, the energetically more ...
در این کار، تاثیر اندازه کلاستر hf روی انتقال پروتون بین hf و آنیلید بوسیله روش های شیمی کوانتمی مورد بررسی قرار گرفته اند. تغییرات قدرت پیوند های هیدروزنی از طریق تغییر اندازه کلاستر hf به خوبی بوسیله انرزی های اتصال، پارامتر های ساختاری، توپوگرافی دانسیته الکترونی و انتقال بار نشان داده شده اند. نتایج ما برای کمپلکس با n=1 در سطح نظری(mp2/6-311++g(2d,2p نشان می دهد که ساختار دارای...
More recently medical chemistry research has been focused on proteins that drive and controlcell cycle progression. Among them, the cyclin dependent kinases (cdk’s) are a group ofserine/threonine kinases, which rule the transition between successive stages of the cell cycle. Theactivity of cdk’s is regulated by multiple mechanisms, including binding to cyclins, which is a broadclass of positive...
Background and Aims: The aim of this study was to evaluate the quality of an experimental hydrofluoric acid (HF) for preparation of porcelain and to compare it with two commercial hydrofluoric acids in Iranian trademark. Materials and Methods: A- Evaluation of etch pattern of experimental HF using scanning electron microscope (SEM): 6 feldespathic discs were divided into 3 groups. Each group w...
Introduction: Medication adherence is essential to improve outcomes emanated from the disease. The increase in the complexity of the medical regimens causes poor adherence in patients with heart failure; also, the progressive nature of Heart Failure (HF) and its complicated drug regimens are mostly stressful. This study has been conducted on the HF patients at the heart hospital of Kermanshah c...
Backgrounds and Aim: Self-care behaviors are an important aspect of Heart Failure (HF), management, Educating self-care behaviors to HF patients have to be a part of routine management of HF in hospitals and health care Centers. The aim of this study was to determine the impact of an educational intervention on self-care behaviors and its perceived benefits and barriers in patients with HF in T...
background and purpose: heart failure (hf) is a chronic, debilitating disease, and physical limitations and progressive symptoms of which associated with this condition can reduce quality of life (qol). patient education regarding heart hf is one of the main components of self-care. in this respect, peer education is significant in improving health and creating a learning environment. this stud...
Background Heart failure (HF) in infants and children with congenital heart disease (CHD) is a crucial complication with different outcomes. Many biomarkers are used as prognostic indicators. Soluble ST2 (sST2) is one of these markers studied in adults with HF. We aimed to study the prognostic value of sST2 in CHD children with HF. Materials and Methods In current case-control study, thirty-six...
A "Qi" feeling (a kind of comfortable sense) during and after acupuncture is one of the important determinants to decide quantity (trial number) of acupuncture stimulation. It has been reported that various autonomic responses were evoked when patients felt "Qi" and when acupuncture stimulation had significant effects on EEGs. However, quantitative relationships among acupuncture stimulation, E...
