Genome-wide association studies (GWAS) in colorectal cancer (CRC) identified five regions near transforming growth factor β-related genes BMP4, GREM1, CDH1, SMAD7 and RPHN2. The true risk alleles remain to be identified in these regions, and their role in CRC risk in non-European populations has been understudied. Our previous work noted significant genetic heterogeneity between African America...
Improving our understanding of cloud chemistry depends on achieving better chemical characterization (90% of the organic carbon [OC] fraction remains uncharacterized) and, consequently, assessing the reactivity of this complex system. In this manuscript, we report for the first time the concentrations of 16 amino acids (AAs) in 25 cloud water samples. The concentrations of individual AAs ranged...
BACKGROUND Albuminuria and reduced glomerular filtration rate (GFR) are markers of renal dysfunction associated with hypertension. We performed genome-wide scans to detect loci impacting these parameters in 1251 African American (AAs) and 1129 European American (EAs) hypertensive siblings from the Hypertension Genetic Epidemiology Network study. METHODS GFR, estimated by the Modification of D...
BACKGROUND Use of anabolic androgenic steroids (AAS) has been associated with adverse physical and psychiatric effects and it is known as rising problem among youth people. This study was conducted to evaluate anabolic steroids preventative intervention efficiency among gym users in Iran and theory of planned behaviour was applied as theoretical framework. METHODS Overall, 120 male gym users ...
Androgens are mainly prescribed to treat several diseases caused by testosterone deficiency. However, athletes try to promote muscle growth by manipulating testosterone levels or assuming androgen anabolic steroids (AAS). These substances were originally synthesized to obtain anabolic effects greater than testosterone. Although AAS are rarely prescribed compared to testosterone, their off-label...
BACKGROUND The high prevalence and potential side effects of anabolic-androgenic steroids (AAS) misuse by athletes has made it a major public health concern. Epidemiological studies on the abuse of such drugs are mandatory for developing effective preventive drug control programs in sports community. This study aimed to investigate the prevalence of AAS abuse and their association with some psy...
In hamsters (Mesocricetus auratus), anabolic-androgenic steroid (AAS) exposure during adolescence facilitates offensive aggression that is correlated with the enhanced development of the arginine vasopressin (AVP) neural system and reduced development of the serotonin (5-HT) neural system in the anterior hypothalamus (AH). This study examined the temporal onset of these effects by measuring agg...
BACKGROUND Despite substantial attention paid to Arab-Americans (AAs) in the media and in public discourse, there is limited research about the health of AAs in the United States (US) in the public health literature. This review aims to synthesize the extant peer-reviewed literature concerned with the health of AAs living in the US. METHODS We summarize existing research on the prevalence, re...
CONTEXT Observations suggest that the use of anabolic androgenic steroids (AAS) may trigger uncontrolled, violent rage. Other observations indicate that certain groups of criminals may use AAS with the intention of being capable of committing crime more efficiently. OBJECTIVE To examine the proposed association between the use of AAS and criminality. DESIGN A controlled retrospective cohort...
