Diabetic kidney disease is the leading cause of ESRD, but few biomarkers of diabetic kidney disease are available. This study used gas chromatography-mass spectrometry to quantify 94 urine metabolites in screening and validation cohorts of patients with diabetes mellitus (DM) and CKD(DM+CKD), in patients with DM without CKD (DM-CKD), and in healthy(More)
BACKGROUND We examined human immunodeficiency virus (HIV) prevalence and correlates among female sex workers (FSWs) in Tijuana and Ciudad Juarez, 2 large cities on the Mexico-US border. METHODS FSWs aged > or =18 years underwent interviews and testing for HIV, syphilis, gonorrhea, and chlamydia. Logistic regression identified factors associated with HIV(More)
Human carcinomas can metabolically incorporate and present the dietary non-human sialic acid Neu5Gc, which differs from the human sialic acid N-acetylneuraminic acid (Neu5Ac) by 1 oxygen atom. Tumor-associated Neu5Gc can interact with low levels of circulating anti-Neu5Gc antibodies, thereby facilitating tumor progression via chronic inflammation in a(More)
BACKGROUND HIV prevalence is increasing among female sex workers (FSWs) in Tijuana and Ciudad Juarez, 2 Mexican cities on the US border. Quasilegal prostitution in both cities attracts large numbers of sex tourists. We compared FSWs with and without US clients in both cities. METHODS FSWs aged > or =18 years reporting unprotected sex with > or =1 client(More)
MOTIVATION Detection and quantification of the absolute DNA copy number alterations in tumor cells is challenging because the DNA specimen is extracted from a mixture of tumor and normal stromal cells. Estimates of tumor purity and ploidy are necessary to correctly infer copy number, and ploidy may itself be a prognostic factor in cancer progression. As(More)
Neuroblastoma is a pediatric cancer with significant genomic and biologic heterogeneity. p16 and ARF, two important tumor-suppressor genes on chromosome 9p21, are inactivated commonly in most cancers, but paradoxically overexpressed in neuroblastoma. Here, we report that exon g in p16 is also part of an undescribed long noncoding RNA (lncRNA) that we have(More)
Dietary intervention trials aim to change dietary patterns of individuals. Participating in such trials could impact dietary self-report in divergent ways: Dietary counseling and training on portion-size estimation could improve self-report accuracy; participant burden could increase systematic error. Such intervention-associated biases could complicate(More)
AIMS The aim of this study was to examine the effect of a case management intervention on retention in opiate agonist therapy among injection drug users (IDUs) referred from a needle exchange program (NEP). DESIGN, INTERVENTION, PARTICIPANTS, AND SETTING: A randomized trial of a strengths-based case management intervention versus passive referral (control)(More)
A cell-based high-throughput screen to identify small molecular weight stimulators of the innate immune system revealed substituted pyrimido[5,4-b]indoles as potent NFκB activators. The most potent hit compound selectively stimulated Toll-like receptor 4 (TLR4) in human and mouse cells. Synthetic modifications of the pyrimido[5,4-b]indole scaffold at the(More)
Dormant leukemia stem cells (LSC) promote therapeutic resistance and leukemic progression as a result of unbridled activation of stem cell gene expression programs. Thus, we hypothesized that 1) deregulation of the hedgehog (Hh) stem cell self-renewal and cell cycle regulatory pathway would promote dormant human LSC generation and 2) that PF-04449913, a(More)
