Objectives Parkinson Disease (PD) is a progressive neurodegenerative disorder affecting motor and cognitive functions. Cognitive impairments are related to different causes such as health indicators. This study aimed to examine the relationship between cognitive impairment and health indicators of patients with PD. Methods & Materials This study was a cross-sectional and descriptive study. B...
Background and Objective: Choline is a precursor for the synthesis of the most important cholinergic neurotransmitter that induce the release of calcium from sarcoplasmic reticulum that finally leads to muscle contraction. The purpose of the current study was to survey the effect of one week choline supplementation on memory, reaction time, throwing darts and balance in recreationally active me...
Introduction: Age-related cognitive decline or cognitive aging is largely the result of structural and functional decline in specific areas of the brain, but lifestyle also contributes to this cognitive decline. The aim of this study was to investigate the effect of working memory rehabilitation on visual memory and memory span in ageing. Methods: This was a quasi-experimental study with pret...
Background: Multiple sclerosis (MS ( is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. Nitric oxide (NO) as a free radical has contradictory effect on the central nervous system and on MS disease. Nitric oxide is one of the distractive factors of the immune system and is a factor in the destruction of myelin. On the other hand, there is an interact...
Objective: The present study was an attempt to examine the difference in the profile of working memory, auditory working memory, and spatial working memory between drug, stimulant, and methadone abusers and normal people. Method: This study was a causal-comparative one with between-group comparison methodology. All the individuals addicted to opiates, stimulants, and methadone who had referred ...
Evidence indicates that medial septum nicotinic receptors regulate cognitive process. Ghrelin is a gut hormone that regulates energy homeostasis. Ghrelin also is produced in brain and known to be involved in cognitive function. The purpose of the study was to evaluate the effects of medial septal injection of ghrelin on morphine-induced memory impairment in rats. Also, the possible relationship...
in this research, shape memory effect of polycaprolactone based polyurethane/poly(vinyl chloride) blends in which the pvc weight percentage are 10, 20, 30, 40, 60 and 80 were studied using dma apparatus. the compatibility, tension and dynamic-mechanical properties of these blends have been studied by the authors and this paper specifically deals with the tests results of shape memory effect. th...
the aim of the present study was to investigate the effect of physical training and working memory training on mental rotation ability. 45 non-athlete female students were purposively selected and randomly assigned to one of these groups: aerobic training, working memory training and control (each group 15 subjects). this study was quasi-experimental, which was a type of pretest-posttest with a...
We address the problem of organizing a set T of shared data into the memory modules of a Distributed Memory Machine (DMM) in order to minimize memory access conflicts during read operations. In this paper we present a new randomized scheme that, with high probability, performs any set of r unrelated read operations on the shared data set T in O(log r + log log |T |) parallel time with no memory...
objective: elevated amino acid homocysteine (hcy) levels and insufficient physical activity are the risk factors in alzheimer disease (ad) development. the effect of intermittent aerobic training on memory retention test and thiobarbituric acid reactive substances (tbars) and superoxide dismutase (sod) levels in the dorsal hippocampus of rats which were stimulated with hcy is investigated. meth...
