BACKGROUND The purpose of this study is to assess attitudes toward premarital dating and sexual encounters in individuals aged 15-49 years in Tehran. METHODS Utilizing the attitudes section of an original cross-sectional study (n = 755) aimed at assessing sexual health needs of adults, this paper examined personal attitudes towards premarital dating, non-sexual relationships and sexual encoun...

OBJECTIVE To analyze the knowledge, attitudes and practices about TB in a prison and in public health services (PHS). METHODS A cross sectional study was carried out and KAP (knowledge, attitudes and practices) questionnaire was applied to 141 prisoners, 115 prison's employees and 158 PHS workers. Epi-Info version 6.04 was used for comparison of proportions with statistic significance at p < ...

background and aim: omega 3 of essential fatty acids, especially in fish oil form plays an important role in structural, functional, and biological aspects in body. omega 3 deficiency can have devastating effects on the nervous system and auditory. this study aimed to evaluate auditory threshold in n-3 fatty acid-deficient rat pups following supplementation of fish oil consumption during the suc...

Lysophosphatidic acid (LPA) is a serum-borne phospholipid that exerts a pleiotropic range of effects on cells through activation of three closely related G-protein-coupled receptors termed LPA1/EDG-2, LPA2/EDG-4 and LPA3/EDG-7. Of these receptors, the LPA1 receptor is the most widely expressed. In this study, we investigated the agonist-induced endocytosis of the human LPA1 receptor, bearing an...

Carbohydrate-deficient transferrins (CDTs), naturally occurring glycosylated transferrin proteins, are reported to be increased in the serum of individuals who consume large quantities of alcohol (ethanol). We compared two methods for the separation and quantification of CDT, using the same alcohol-dependent patients and age-, gender-, and race-matched controls as sources of samples for both as...

Serum concentration of carbohydrate-deficient transferrin (CDT) is used for laboratory diagnosis of chronic alcohol abuse. Using isoelectric focusing for validation of the initial isotransferrin fractionation step involved in the determination of CDT by the CDTect assay, we found a complete in vitro iron saturation of transferrin and sufficient stability of the transferrin iron load during colu...

Two studies examined restrained and unrestrained eaters' implicit and explicit attitudes toward fatness and thinness. Participants completed measures of implicit and explicit attitudes toward fatness and thinness (Studies 1 and 2), and a measure of the internalization of sociocultural attitudes toward thinness (Study 2). Restrained and unrestrained eaters both had strong implicit negative attit...

Smith’s (1993) paper is very welcome in that it stimulates a much needed debate on raising research standards in the study of sexual networks and the transmission of HIV/AIDS. Nevertheless, his paper is difficult to grapple with in that he has several targets, including perhaps population-based epidemiology itself. At least one would derive that impression from his insistence that the focus sho...

The U.S. economic development in the nineteenth century is characterized by the westward movement of population and the accumulation of productive land in the West. What are the quantitatively important forces driving this phenomena? This paper presents a model of migration and land improvement, to address this question. Counterfactual experiments reveals that two forces are key in accounting f...
