Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

  Although cisplatin is one of the most effective cancer drugs which is widely used in the treatment of various neoplasms, its side effects, especially vomiting may limit its use. It has been demonstrated that cytotoxic drugs lead to a sudden release of serotonin (5-HT). The following study was performed to determine the possible interactions of cisplatin with 5-HT receptors. In this study, the...

INTRODUCTION Obesity management guidelines specify initial goals for participation and weight reduction for the first 6 months of a weight-reduction intervention, but guidelines do not specify when to assess early response and make adjustments. We aimed to determine whether very early or early weight reduction in the weight-reduction program MOVE! predicted later participation or achievement of...

statement of problem: despite the wide range of new dental materials, there is still a need for biomaterials demonstrating high biocompatibility, antimicrobial effects and ideal mechanical properties. purpose: the aim of this study was to histologically evaluate the pulpal response to a conventional glass ionomer, a resin modified glass ionomer and a calcium hydroxide in human teeth. materials ...

abstract coontail (ceratophyllum demersum) and watermilfoil (myriophyllum spicatum) are current submersed weeds in many fresh waters of iran. the excessive growth of these plants causes the reduction in utilization of water resources and making some ecological and economical damages in these areas. the aim of this study was to determine the response of two submerged aquatic weeds of coontail an...

There is a close epidemiological association between obesity and blood pressure for all age groups, although not every obese individual becomes hypertensive. In populations without age-related increases in body weight, an elevation of blood pressure with age is not seen. Treatment of obesity by weight loss decreases blood pressure substantially; however, in a minority of patients blood pressure...

Recent research indicates that the warming of the climate system resulting from increased greenhouse gas (GHG) emissions over the next century will persist for many centuries after the cessation of these emissions, principally because of the persistence of elevated atmospheric carbon dioxide (CO2) concentrations and their attendant radiative forcing. However, it is unknown * Corresponding autho...

There is a close epidemiological association between obesity and blood pressure for all age groups, although not every obese individual becomes hypertensive. In populations without agerelated increases in body weight, an elevation of blood pressure with age is not seen. Treatment of obesity by weight loss decreases blood pressure substantially; however, in a minority of patients blood pressure ...
