BACKGROUND Obesity indices (i.e. BMI, waist-to-hip ratio) show differential relationships to other health outcomes, though their association to neurocognitive outcome is unclear. METHODS We examined whether central obesity would be more closely associated with cognitive function in 1,703 participants from the Baltimore Longitudinal Study of Aging. RESULTS Longitudinal mixed-effects regressi...
Most birds rely on flight for survival. Yet as an energetically taxing and physiologically integrative process, flight has many repercussions. Studying pigeons (Columba livia) and employing physiological and immunological indices that are relevant to ecologists working with wild birds, we determined what, if any, acute immune-like responses result from bouts of intense, non-migratory flight. We...
In order to evaluate the growth indices and effective morphological and physiological traits of spring wheat (Triticum aestivum L.) using the multivariate statistical method, an experiment was conducted on the basis of randomized complete block design with three replications in Meshkin Shahr, Ardabil province in 2007. During and at the end of the growth season some physiological and morphologic...
abstract many indices designed by researches for study of human-biometeorology and bioclimatology that today broadly using for assessing the relationships between the climate and tourism .among the proposed indices, thermo- physiological indices as pet and pmv that derived from human energy balance models, important from others. to define of proper calendar for tourism in tabriz we have used of...
Background & Objectives : Exposure to high temperatures is common among workers in warm environments leading to some undesirable effects . The aim of this study was to examine physiological responses to heat stress to determine the optimal index for direct measurement of physiological strain in workers of hot environments . Methods: In this study, 40 workers of melting and cast...
Introduction: Hypothermia is a common and serious complication that occurs in patients undergoing laparoscopic surgery. Additionaly, various warming methods are used to prevent these conditions in the operating room. The aim of this study was to compare the effect of two warming methods on physiological indices of patients undergoing laparoscopic cholecystectomy. Materials and Methods: In a cl...
To investigate the effect of on-farm seed priming and bio-fertilizers at different phosphorus levels on some physiological indices of chickpea (Cicer arietinum L.) a factorial experiment was conducted in spring 2013 in a randomized complete block design with 3 replications at the Agricultural Research Station of Bu Ali Sina University in Hamedan, Iran. The factors consisted of phosphorus fertil...
Introduction: Heat stress is a critical problem in hot industries, especially in incredibly hot climates. It can greatly impair the work process and put the health of workers at risk. This study aims to investigate the applicability of the WBGT index in determining the allowable working time in very hot weather conditions in one of the steel industries in Ahvaz. Material and Methods: This stud...
BACKGROUND Various indices have been raised as predictors of activity and severity of juvenile idiopathic arthritis. OBJECTIVES This study was conducted to investigate the changes of platelet indices in acute phase and two months after treatment in these patients. PATIENTS AND METHODS In a cohort study, platelet count, mean platelet volume (MPV), platelet distribution width (PDW), plateletc...
the current study was carried out to examine sugar beet growth pattern in climatic conditions of hamedan, iran and to recognize the factors affecting its quantity and quality as well as the physiological indices. two sowing date experiments were conducted on the basis of a randomized complete block design with four replications and 11 harvests. the plots were destructively sampled and the growt...
