Several studies have been devoted to calibrate damage indices for steel and reinforced concrete members with the purpose of overcoming some of the shortcomings of the parameters currently used during seismic design. Nevertheless, there is a challenge to study and calibrate the use of such indices for the practical structural evaluation of complex structures. In this paper, an energy-based damag...
Background Beta-hydoxy-beta-methyl butyrate (HMB) when given over a two-week period of time (loading phase) has been demonstrated to decrease skeletal muscle damage, and improve recovery. However, few studies have investigated its acute effects on muscle damage and recovery. Therefore the purpose of this investigation was to determine the effects of short term free acid HMB (HMB-FA) supplementa...
Background: The role of the renin-angiotensin-aldosterone system in the pathophysiology of target organ damage in hypertension is still under investigation. The angiotensinogen M235T and aldosterone synthase C-344T gene polymorphisms may be associated with vascular indices, renal function and left ventricular hypertrophy thus, we sought to investigate their potential associations with preclinic...
Whether target organ damage is associated with blood pressure (BP) variability independent of level remains debated. We assessed these associations from 10-minute beat-to-beat, 24-hour ambulatory, and 7-day home BP recordings in 256 untreated subjects referred to a hypertension clinic. BP variability indices were variability independent of the mean, maximum-minimum difference, and average real ...
PURPOSE To evaluate the relationship between the structural damage as assessed by time-domain optical coherence tomography (OCT) and functional changes in glaucoma. METHODS In total, 190 patients with normal tension glaucoma or primary open angle glaucoma were included in this study. The thickness of retinal nerve fiber layer (RNFL) around the optic disc and the area of RNFL defect were deter...
The present study presents an algorithm that models uncertainties at the structural component level to estimate the performance reliability of RC structures. The method calculates the performance reliability using a systemic approach and incorporates the improved response surface method based on sampling blocks using the first-order reliability method and conditional reliability indices. The re...
Background and Objective: The proportional practice protocol is an important issue for middle-aged women to start a health and energetic life style. Aerobic training is proposed as the first and best method of practice for all individuals. However, this protocol is not without damage, because this method like other methods can lead to some cellular disorders, especially muscle cell disorde...
