Adversity, particularly in early life, can cause illness. Clues to the responsible mechanisms may lie with discovery of molecular signatures stress, some which include alterations an individual's somatic genome. Here, using genome sequences from 11,670 women, we observed a highly significant association between stress-related disease, major depression, and amount mtDNA (p = 9.00 × 10(-42), odds ratio 1.33 [95% confidence interval [CI] 1.29-1.37]) telomere length 2.84 10(-14), 0.85 CI...

The objective of our study was to compare the ablation zones two cooled-shaft microwave antennae-one operating at 915 MHz and one 2,450 MHz-in in vivo porcine livers.The 915-MHz antenna can lead deeper penetration liver tissue yield a significantly larger zone than 2,450-MHz livers. In light result, microwaves may be more effective for tumor ablation, especially large tumors.

Abstract Background Schizophrenia is a complex psychiatric disorder with unknown etiology. A number of recent studies have shown that the polymorphism neural precursor cell expressed developmentally down-regulated 4 ( NEDD4 ) gene associated variety neuropsychiatric disorders, such as schizophrenia, and may also be cognitive dysfunction in these diseases. Methods case-control study was carried out, alleles genotypes distributions five loci (rs3088077, rs2303579, rs7162435, rs11550869,...

The gene – environment (G × E) interaction effect is involved in severe mental disorders. However, whether the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism participates childhood-abuse influenced schizophrenic symptoms remains unclear. We examined between BDNF Val66Met, and childhood trauma (ChT) on psychotic a Chinese Han population. To estimate G E interaction, psychiatric interviews, self-report questionnaires for ChT, genotyping were carried out 201 patients....
