Microbiome-mediated suppression of carcinogenesis may open new avenues for identification of therapeutic targets and prevention strategies in oncology. Histidine decarboxylase (HDC) deficiency has been shown to promote inflammation-associated colorectal cancer by accumulation of CD11b(+)Gr-1(+) immature myeloid cells, indicating a potential antitumorigenic effect of histamine. Here, we demonstrate that administration of hdc(+)Lactobacillus reuteri in the gut resulted in luminal hdc gene expression and histamine production in the intestines of Hdc(-/-) mice...

REVIEW
Ganesh Rao
Intraoperative MRI (iMRI) is a neurosurgical adjunct used to maximize the removal of glioma, the most common primary brain tumor. Increased extent of resection of gliomas has been shown to correlate with longer survival times. iMRI units are variable in design and magnet strength, which can affect patient selection and image quality. Multiple studies have shown that surgical resection of gliomas using iMRI results in increased extent of resection and survival time. Level II evidence supports the use of iMRI in the surgical treatment of glioma...

G-quadruplex (G4) secondary structures have been implicated in various biological processes including gene expression, DNA replication and telomere maintenance. However, unresolved G4 structures impede replication progression which can lead to generation of DNA double-strand breaks and genome instability. Helicases have been shown to resolve G4 structures to facilitate faithful duplication of the genome. Escherichia coli UvrD (EcUvrD) helicase plays a crucial role in nucleotide excision repair, mismatch repair and in the regulation of homologous recombination...

Obesity is a major global epidemic that sets the stage for diverse multiple pathologies, including cardiovascular disease. The obesity-related low-grade chronic inflamed milieu is more pronounced in aging and responsive to cardiac dysfunction in heart failure pathology. Metabolic dysregulation of obesity integrates with immune reservoir in spleen and kidney network. Therefore, an integrative systems biology approach is necessary to delay progressive cardiac alternations. The purpose of this comprehensive review is to largely discuss the impact of obesity on the cardiovascular pathobiology in the context of problems and challenges, with major emphasis on the diversified models, and to study cardiac remodeling in obesity...

Pulmonary hypertension (PH) is a devastating pulmonary vascular disease characterized by aberrant muscularization of the normally non-muscularized distal pulmonary arterioles. The expression of the transcription factor, Twist1, increases in the lungs of pulmonary arterial hypertension patients. However, the mechanisms by which Twist1 controls the pathogenesis of PH remain unclear. It is becoming clear that endothelial-to-mesenchymal transition (EndMT) contributes to various vascular pathologies including PH; Twist1 is known to mediate EndMT...

The FANCJ DNA helicase is linked to hereditary breast and ovarian cancers as well as bone marrow failure disorder Fanconi anemia (FA). Although FANCJ has been implicated in the repair of DNA double-strand breaks (DSBs) by homologous recombination (HR), the molecular mechanism underlying the tumor suppressor functions of FANCJ remains obscure. Here, we demonstrate that FANCJ deficient human and hamster cells exhibit reduction in the overall gene conversions in response to a site-specific chromosomal DSB induced by I-SceI endonuclease...

INTRODUCTION: According to the various independent studies conducted, it is well evident fact that radiation induces oxidative stress in the living system. It is also proved that this oxidative stress will lead to the various behavioural changes such as anxiety and memory impairment. Kinetin is one of the important plant cytokine with anti-aging properties. However, very few studies were conducted to check its potential in ameliorating the behavioural changes induced by the ionizing radiation...

Diaphragmatic eventration is an uncommon malady, underdiagnosed and often treated only in emergent situations. Eventration of the diaphragm is best treated by plication of diaphragm with or without meshplasty. Various studies have shown that thoracoscopic plication is as efficient as laparotomy or laparoscopic plication. We present here the report of thoracoscopic diaphragmatic plication for eventration performed in the third trimester of pregnancy in a 28-year-old woman who presented with acute respiratory distress...

Normothermic ex vivo kidney perfusion (NEVKP) represents a novel approach for graft preservation and functional improvement in kidney transplantation. We investigated whether NEVKP also allows graft quality assessment prior to transplantation. Kidneys from 30kg pigs were recovered in a model of heart-beating donation (HBD) (group A), following 30min of warm ischemia (WI) (group B), or 60min WI (group C) (n=5/group). Following 8hrs of NEVKP, contralateral kidneys were resected, grafts autotransplanted, and pigs followed for 3 days...

A transition-metal-free method for the construction of functionalized quinolines from readily available acetophenones and anthranils is reported. This one-pot reaction cascade involves in situ generation of α,β-unsaturated ketones from the acetophenone via one-carbon homologation by DMSO followed by the aza-Michael addition of anthranils and subsequent annulation. DMSO acted in this reaction not only as solvent but also as one carbon source, thus providing a highly atom-economical and environmentally benign approach for the synthesis of 3-substituted quinolines...
