5-Hydroxymethylcytosine (5hmC) is a modified form of cytosine, which has recently been found in mammalian cells and tissues. 5hmC is derived from 5-methylcytosine (5mC) by Ten-eleven translocation (TET) family protein-mediated oxidation and may regulate gene expression. Numerous affinity-based profiling methods have been developed to help understand the exact function of 5hmC in the genome. However, these methods have a relatively low resolution (~100 bp) without quantitative information of the modification percentage on each site...

Because of its own unfavourable evolution, HIV infection was until recently considered a contraindication for organ transplantation. The introduction of highly active antiretroviral therapy prolonged the life expectancy of these patients and allowed the manifestation of disorders directly or indirectly related to HIV infection, mainly liver, kidney and cardiovascular diseases. We present a case of cardiac transplantation due to dilated cardiomyopathy that was performed in a patient with a recently detected HIV infection...

BACKGROUND: Childhood trauma has long-term adverse effects on physical and psychological health. Previous studies demonstrated that suicide and mental disorders were related to childhood trauma. In China, there is insufficient research available on childhood trauma in patients with mental disorders. METHODS: Outpatients were recruited from a psychiatric hospital in southern China, and controls were recruited from local communities. The demographic questionnaire, the Childhood Trauma Questionnaire-Short Form (CTQ-SF), and the Social Support Rating Scale (SSRS) were completed by all participants, and the Self-rating Idea of Suicide Scale (SIOSS) were completed only by patients...

Dissolved black carbon (DBC) is ubiquitous in aquatic systems, being an important subgroup of the dissolved organic matter (DOM) pool. Nevertheless, its aquatic photoactivity remains largely unknown. In this study, a range of spectroscopic indices of DBC and humic substance (HS) samples were determined using UV-Vis spectroscopy, fluorescence spectroscopy, and proton nuclear magnetic resonance. DBC can be readily differentiated from HS using spectroscopic indices. It has lower average molecular weight, but higher aromaticity and lignin content...

Social anxiety disorder (SAD) is a common and disabling condition characterized by excessive fear and avoidance of public scrutiny. Neuroimaging studies have suggested that the emotional and behavior deficits in SAD are associated with abnormalities in regional brain function and functional connectivity. However, little is known about whether intrinsic functional brain networks in patients with SAD are topologically disrupted. Here, we collected resting-state fMRI data from 33 drug-naive patients with SAD and 32 healthy controls (HC), constructed functional networks with 34 predefined regions based on previous meta-analytic research with task-based fMRI in SAD, and performed network-based statistic and graph-theory analyses...

Liver fibrosis is overly exuberant wound healing that leads to portal hypertension or liver cirrhosis. Recent studies have demonstrated the functions of bone morphogenetic protein 9 (BMP9) in liver fibrosis, and thus, targeting liver-specific BMP9 abnormalities will become an attractive approach for developing therapeutics to treat liver fibrosis. Here, we reveal that BMP9 serves as a valuable serum diagnostic indicator and efficient therapeutic target to attenuate liver fibrogenesis. Our analysis of biopsies from liver fibrotic patients revealed that higher BMP9 levels accompanied advanced stages of liver fibrosis...

MYB transcription factors are involved in the regulation of plant development and response to biotic and abiotic stress. In this study, TaMyb1D, a novel subgroup 4 gene of the R2R3-MYB subfamily, was cloned from wheat (Triticum aestivum L.). TaMyb1D was localized in the nucleus and functioned as a transcriptional repressor. The overexpression of TaMyb1D in tobacco (Nicotiana tabacum) plants repressed the expression of genes related to phenylpropanoid metabolism and down-regulated the accumulation of lignin in stems and flavonoids in leaves...

BACKGROUND Native vertebral osteomyelitis (NVO) is a common form of hematogenous osteomyelitis, with Staphylococcus aureus (S. aureus) being the most commonly isolated organism. Dalbavancin is approved by the US Food and Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and has a sufficiently promising pharmacokinetic and pharmacodynamic profile to be considered for the treatment of vertebral osteomyelitis. We describe here what is probably the first reported case of using multiple weekly dalbavancin to treat a complicated methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and vertebral osteomyelitis...

Defective nucleotide modifications of mitochondrial tRNAs have been associated with several human diseases, but their pathophysiology remains poorly understood. In this report, we investigated the pathogenic molecular mechanism underlying a hypertension-associated 4435A>G mutation in mitochondrial tRNAMet The m.4435A>G mutation affected a highly conserved adenosine at position 37, 3' adjacent to the tRNA's anticodon, which is important for the fidelity of codon recognition and stabilization. We hypothesized that the m...
