BACKGROUND: A functional polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene, namely C677T (rs1801133), results in increased Hcy levels and has been associated with risk of late-onset Alzheimer's disease (LOAD). Many investigators reported association between rs1801133 and LOAD risk in Asian populations and in carriers of the apolipoprotein E (APOE) ɛ4 allele, but recent meta-analyses suggest a contribution also in other populations, including Caucasians and/or northern Africans...

BACKGROUND: Gastric cancer is a heterogeneous disease with variable presentation between racial and ethnic groups. Staging laparoscopy (SL) detects occult metastases not visible on cross-sectional imaging and therefore improves staging. It remains unclear how differences in race and ethnicity affect disease presentation and the yield of SL. METHODS: We performed a retrospective review of a prospectively maintained database to identify patients with gastric cancer treated with curative intent at our institutions from 2008 to 2015...

Infection of pregnant women by Asian lineage strains of Zika virus (ZIKV) has been linked to brain abnormalities in their infants, yet it is uncertain when during pregnancy the human conceptus is most vulnerable to the virus. We have examined two models to study susceptibility of human placental trophoblast to ZIKV: cytotrophoblast and syncytiotrophoblast derived from placental villi at term and colonies of trophoblast differentiated from embryonic stem cells (ESC). The latter appear to be analogous to the primitive placenta formed during implantation...

Lack of regular HIV testing puts African American, Asian, and Latino men who have sex with men (MSM) at high risk for HIV infection. Rapid self-testing may be an effective option for these men. We explored acceptability, preferences, and usability of HIV self-test kits with MSM of color using semi-structured focus groups to discuss HIV testing history, reasons for testing, and self-testing preferences. Participants (n = 21) lived in Los Angeles, identified as MSM of color, and were 18-35 years of age. Discussions were audio-recorded, transcribed, and analyzed using grounded theory...

PURPOSE: Asians have some of the highest rates of end-stage renal disease, but there is limited information on the risk factors for chronic kidney disease (CKD) in the Asian general population. A risk score for incident CKD for the general population has been developed from the US Framingham Heart Study (FHS) Offspring cohort. This score has been validated on Caucasians and African-Americans, but has not been tested on Asians. We aimed to assess the importance of the FHS risk factors and the performance of the FHS risk score in predicting incident CKD at 10 years in a Thai community-based population...

Character development in adolescence is of growing interest among psychology researchers and educators, yet there is little consensus about how character should be defined and studied among developmental scientists. In particular, there is no fully developed framework for investigating the developmental relationships among different character strengths. This study examines the developmental relations between purpose and three other key character strengths that emerge during early adolescence: gratitude, compassion, and grit...

BACKGROUND: GPRC6A, a widely expressed G-protein coupled receptor, is proposed to be a master regulator of complex endocrine networks and metabolic processes. GPRC6A is activated by multiple ligands, including osteocalcin (Ocn), testosterone (T), basic amino acids, and various cations. SCOPE OF REVIEW: We review the controversy surrounding GPRC6A functions. In mice, GPRC6A is proposed to integrate metabolic functions through the coordinated secretion of hormones, including insulin, GLP-1, T, and IL-6, and direct effects of this receptor to control glucose and fat metabolism in the liver, skeletal muscle, and fat...

BACKGROUND: Hypertension is a major risk factor for cardiovascular disease and prevalence varies by ethnic group. The diagnosis and management of blood pressure are informed by guidelines largely based on data from white populations. This study addressed whether accuracy of blood pressure measurement in terms of diagnosis of hypertension varies by ethnicity by comparing two measurement modalities (clinic blood pressure and home monitoring) with a reference standard of ambulatory BP monitoring in three ethnic groups...

The escalating growth in illegal wildlife trade (IWT) and anthropogenic habitat changes threaten the survival of pangolin species globally. All eight extant species have experienced drastic population size reductions globally with high extinction risk in Asia. Consequently, forensic services have become critical for law enforcement of IWT, with a need for standardised and validated genetic identification methods. The seizure of three tonnes of pangolin scales, originating from Africa, by the Hong Kong Customs Authority provided an opportunity for the forensic application of DNA barcoding for identification...

INTRODUCTION: Race may be a significant factor that influences prostate cancer (PCa) survival, with the Asian (AsA) race being associated with better outcomes compared to African American (AA) and Non-Hispanic Whites (NHW). This study evaluates race-dependent variation in PCa-specific mortality (PCSM) associated with radiation dose-escalation exemplified by external beam radiotherapy (EBRT) with a brachytherapy (BT) boost in Gleason score 8-10 PCa. METHODS: 28,956 men diagnosed with clinically localized PCa and Gleason score 8-10 from 2004-2013 who received EBRT, EBRT with a BT boost, or radical prostatectomy (RP) were identified using the Surveillance, Epidemiology, and End Results (SEER) database...

Among the human health conditions linked to microbial communities, phenotypes are often associated with only a subset of strains within causal microbial groups. While it has been critical for decades in microbial physiology to characterize individual strains, this has been challenging when using culture-independent high-throughput metagenomics. We introduce StrainPhlAn, a novel metagenomic strain identification approach, and apply it to characterize the genetic structure of thousands of strains from >125 species in >1,500 gut metagenomes drawn from populations spanning North/South American, European, Asian, and African countries...
