Despite advances in the treatment of suicidality over the last decade, a significant proportion of veterans with suicidal ideation do not utilize mental health treatment. To date, however, few population-based studies have examined factors that may facilitate or impede mental healthcare engagement among veterans currently contemplating suicide. This study examined barriers and facilitators of current mental healthcare utilization in a nationally representative sample of U.S. military veterans who endorsed current suicidal ideation. Using data from the National Health and Resilience in Veterans Study (n=3157), collected in 2011, multivariable analyses were conducted to identify predisposing (e.g., age), enabling (e.g., social support), and need (e.g., psychiatric history) characteristics, as well as perceptions of stigma and barriers to care, associated with current mental healthcare utilization. A total of 7.3% (n=231) of veterans endorsed current suicidal ideation, of which 36.1% (n=84) were engaged inceptions of stigma and negative beliefs about mental healthcare in this population.Phosphoenolpyruvate carboxylase (PEPC) is a carbon fixation enzyme which probably plays crucial roles in seed development. A greater number of PEPC isoforms are encoded in the soybean genome, while most of the PEPC isoforms are functionally unknown. In this study, we investigated on soybean PEPC expressed in the external layer of seed coat (ELSC) during seed formation. PEPC activity in ELSC ranged from 0.24 to 1.0 U/g F.W., which could be comparable to those in whole seeds at U per dry matter. Public RNA-Seq data in separated soybean seed tissues revealed that six plant-type PEPC isogenes were substantially expressed in ELSC, and Gmppc1 and Gmppc7 were highly expressed in hourglass cells of ELSC. Gene Ontology enrichment of co-expressed genes with Gmppc1 and Gmppc7 implicated a role of these isogenes in assisting energy production and cellulose biosynthesis. Comparison of PEPC sequences from 16 leguminous species hypothesized adaptive evolution of the Gmppc1 and Gmppc7 lineage after divergence from the other plant-type PEPC lineages. Molecular diversification of these plant-type PEPC was possibly accomplished by adaptation to the functions of the soybean seed tissues. This study indicates that energy demand in immature seeds may be a driving force for the molecular evolution of PEPC.Mitochondrial DNA (mtDNA) copy number and mitochondrial DNA haplogroups have been associated with different types of cancer, including breast cancer, because they alter cellular energy metabolism. However, whether mtDNA copy number or haplogroups are predictors of oxidative stress-related risks in human breast cancer tissue in Mexican patients remains to be determined. Using quantitative real-time PCR assays and sequencing of the mtDNA hypervariable region, analysis of mtDNA copy numbers in 82 breast cancer tissues (BCT) and matched normal adjacent tissues (NAT) was performed to determine if copy number correlated with clinical features and Amerindian haplogroups (A2, B2, B4, C1 and D1) . The results showed that the mtDNA copy number was significantly decreased in BCT compared with NAT (p = 0.010); it was significantly decreased in BCT and NAT in women > 50 years of age, compared with NAT in women less then 50 years of age (p = 0.032 and p = 0.037, respectively); it was significantly decreased in NAT and BCin sequences containing C16111T, G16319A or T16362C polymorphisms (p = 0.021, =0.048, and = 0.001; respectively). In conclusion, a decrease in the copy number of mtDNA in BCT compared with NAT was shown by the results, which suggests an imbalance in oxidative phosphorylation (OXPHOS) that can affect the apoptosis pathway and cancer progression. It was also observed an increase of the copy number in samples with specific polymorphisms, which may be a good sign of favourable prognosis.The CRISPR-Cas system currently stands as one of the bes
