many studies indicate that oxidative stress is involved in the pathophysiology of neurodegenerative diseases. oxidative stress can induce neuronal damages, modulate intracellular signaling and ultimately leads to neuronal death by apoptosis or necrosis. to review antioxidants preventive effects on oxidative stress and neurodegenerative diseases we accumulated data from international medical jou...

Low back pain is one of the most prevailing illnesses, which is paramount importance among disabling illnesses. Inspite of being various factors for low back pain the main course of it hasnot been recognised yet. In this study we investigated the effects of two methods on treating chronic tension myositis syndrom. That is one kind of low back muscles spasm due to high stress and psychic problem...

The authors tested the hypothesis that activity inhibition (AI), a measure of the frequency of the word "not" in written material, marks a propensity to engage functions of the right hemisphere (RH) and disengage functions of the left hemisphere (LH), particularly during stress. Study 1 and Study 2 showed that high AI predicts faster detection of stimuli presented to the RH, relative to the LH....

The purpose of this paper was to identify factors associated with breastfeeding among mothers of children born in 1994 in five of the low income communities participating in the longitudinal prevention initiative "Better Beginnings, Better Futures." Household income was < or = poverty line for 76%, 63% had completed high school or beyond, and 29% were born outside of Canada. The breastfeeding i...

Atherosclerosis begins as local inflammation of arterial walls at sites of disturbed flow, such as vessel curvatures and bifurcations with low shear stress. c-Jun NH₂-terminal kinase (JNK) is a major regulator of flow-dependent gene expression in endothelial cells in atherosclerosis. However, little is known about the in vivo role of JNK in low shear stress in atherosclerosis. We aimed to obser...

The aim of this prospective quasi-experimental study was to assess the role of coping style as a factor moderating the relationship between stress and sleep. Sleep of 36 students was assessed by means of actigraphy and daily logs during low-stress and high-stress periods. The high-stress period was the week that the students were evaluated for acceptance to graduate programs in clinical psychol...

drought and salinity are two important environmental stresses limiting the crop production. in order to study the influence of drought and salinity stresses on germination characteristics of marshmallow plant seeds, two separate experiments were conducted based on completely randomized design with four replications in controlled conditions. drought stress levels were 0, -2, -4, -6 and -8 bar in...

According to the family stress model (Conger & Donnellan, 2007), low socioeconomic status (SES) predicts less-than-optimal parenting through family stress. Minority families generally come from lower SES backgrounds than majority families, and may experience additional stressors associated with their minority status, such as acculturation stress. The primary goal of this study was to test a min...

in order to study the effects of drought stress and nitrogen (n) levels on grain yield, yield components and water use efficiency of grain corn (sc.704), a field experiment was conducted in 2009 growing season. the experiment was split-plot based on randomized complete block design arrangement and four replicates. main plots were three irrigation levels included optimum irrigation (i1), moderat...
