we aimed to evaluate the potential of growing rats as a model of osteoporosis induced by short term hypercholesterolemia. twelve growing female sprague-dawley rats were randomly allocated into two groups. control rats received standard diet while rats in group 2 were fed with diet contained 20% sunflower oil, 2% cholesterol and 0.5% cholic acid for 2 weeks and then a diet contained 10% sunflowe...

abstract background: conflict is the lack of agreement and disagreement between the two men, and behavioral maladjustment or objectives that are in opposition to the other. destructive conflicts are incidents imposed on one or more than one member of the family or the whole family and affect on them. the purpose of this research is to study the effect of solution - focused short-term approach o...

BACKGROUND Air pollution exposure during pregnancy has been associated with adverse birth outcomes and health problems later in life. We investigated sex-specific transcriptomic responses to gestational long- and short-term exposure to particulate matter with a diameter < 2.5 μm (PM2.5) in order to elucidate potential underlying mechanisms of action. METHODS Whole genome gene expression was i...

We have previously shown that nicotine, the addictive component of tobacco products, alters the blood-brain barrier (BBB) Na(+),K(+),2Cl(-) cotransporter (NKCC) during in vitro hypoxia-aglycemia exposure. Attenuation of abluminal NKCC suggests that accumulation of ions in the brain extracellular fluid would result in an increase of fluid or cytotoxic edema in the brain during hypoxia-aglycemia ...

Short-term response to cold promotes a small but significant rise in serum T3 in euthyroid rabbits, where the heart is an important target of T3 action. In this work, we measured changes in sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA2a) and phospholamban (PLB) in hearts of hypo- and hyperthyroid rabbits and compared them with modifications induced by short- and long-term cold exposure. Sh...

OBJECTIVE To investigate whether the saccule exhibits temporary or permanent functional loss resembling threshold shifts in auditory brainstem response (ABR) of guinea pigs following noise exposure. DESIGN Randomly bred guinea pigs were divided into 3 groups: A (short-term noise exposure, 30 minutes, n = 15), B (long-term noise exposure, 40 hours, n = 9), and C (no noise exposure, n = 5). S...

Cardiovascular disease is the leading cause of death in the world. It is responsible for ≈30% of all deaths or ≈17.5 million people in 2012. As the major risk factor for cardiovascular disease, hypertension has been identified as the most important cause of disability and the leading risk factor for death globally and causes ≈16.5% of all deaths. The causes of hypertension are complex and are r...

review and classification of electric load forecasting (lf) techniques based on artificial neuralnetworks (ann) is presented. a basic anns architectures used in lf reviewed. a wide range of annoriented applications for forecasting are given in the literature. these are classified into five groups:(1) anns in short-term lf, (2) anns in mid-term lf, (3) anns in long-term lf, (4) hybrid anns inlf,...
