Perfluorooctanoic acid (PFOA), a perfluoroalkyl substance, is commonly detected in the serum of pregnant women and may impact fetal development via epigenetic re-programming. In a pilot study, we explored associations between serum PFOA concentrations during pregnancy and offspring peripheral leukocyte DNA methylation at delivery in women with high (n = 22, range: 12-26ng/mL) and low (n = 22, range: 1.1-3.1ng/mL) PFOA concentrations. After adjusting for cell type, child sex, and income, we did not find differences in CpG methylation in the two exposure groups that reached epigenome-wide significance...

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are considered chemicals of emerging concern, in part due to their environmental and biological persistence and the potential for widespread human exposure. In 2007, a PFAS manufacturer near Decatur, Alabama notified the United States Environmental Protection Agency (EPA) it had discharged PFAS into a wastewater treatment plant, resulting in environmental contamination and potential exposures to the local community. OBJECTIVES: To characterize PFAS exposure over time, the Agency for Toxic Substances and Disease Registry (ATSDR) collected blood and urine samples from local residents...

PURPOSE: Almost half of all patients diagnosed with schizophrenia have a history of substance abuse (SA). However, data on treatment of schizophrenia with paliperidone palmitate (PP) among patients with comorbid SA are limited. The objective of this study was to compare all-cause and SA-related health care resource utilization and costs in veterans with schizophrenia and co-occurring SA who were treated with PP versus oral atypical antipsychotics (OAAs). METHODS: Veterans Health Administration electronic health record data were used to conduct a retrospective longitudinal study in veterans with schizophrenia who initiated PP or OAA between January 1, 2010 and June 30, 2016, had ≥12 months of enrollment before treatment initiation (baseline), were diagnosed with SA, and had ≥1 Global Assessment of Functioning score during baseline...

The goals of this study were to describe the morphology, neurotransmitter content and synaptic connections of neurons in primate retinas that contain the neuropeptide secretoneurin. Amacrine cells were labeled with antibodies to secretoneurin in macaque and baboon retinas. Their processes formed three distinct plexuses in the inner plexiform layer: one in the outermost stratum, one in the center and one in the innermost stratum. In light microscopic double immunolabeling experiments, GABA was colocalized with secretoneurin in these cells, but glycine transporter 1 and Substance P were not...

Soil-derived dissolved organic matter (DOM) has a major influence in biogeochemical processes related to contaminant dynamics and greenhouse gas emissions, due to its reactivity and its bridging role between the soil and aquatic systems. Within the Three Gorges Reservoir (TGR, China) area, an extensive water-fluctuation zone periodically submerges the surrounding soils. Here we report a characterization study of soil-derived DOM across the TGR areas, using elemental and optical analysis, infrared spectroscopy (FTIR), pyrolysis-GC-MS (Py-GC-MS) and thermally assisted hydrolysis and methylation (THM-GC-MS)...

Increasingly, three generation studies have investigated intergenerational (IG) continuity and discontinuity in substance use and related problem behaviors. However, surprisingly little attention has been paid to the conceptual definition of continuity or to different types of discontinuity (resilience and escalation) or to measurement sensitivity, which affects not only the magnitudes of observed continuity but also factors that correlate with this linkage. This study uses longitudinal data on 427 parent-child dyads from the Rochester IG Study to study continuity and discontinuity in substance use over ages 14-18...

Imaging biofilm-encased microorganisms is challenging due to them being shielded by a sticky and strong extracellular polymeric substance matrix that blocks the penetration of dyes, but is especially important for biofilm study. Here, carbon dots, namely CDs-605, were used for successfully imaging biofilm-encased microorganisms. We demonstrated that such CDs-605 could be easily synthesized from L. plantarum by one-step hydrothermal carbonization. The negatively charged CDs-605 were composed of C, H, O, N, P, and S and contained various functional groups, including -OH, -COOH, and -CONH-...

Involvement in dating violence has been linked with negative health outcomes including depressive symptomology, substance use, and later expressions of aggressing and victimizing behaviors. Less is known about the prevalence and mental health correlates of teen dating violence in countries like Mexico where adult partner violence is high. Additional research on teen dating violence is also needed, as it may be an important precursor to adult partner violence and linked to other mental health problems. The current study used self-report ratings to assess the similarities and differences in risk factors associated with dating violence among middle school students in Mexico and the United States...
