Overexpressions of DLL4 and CD105 are Associated with Poor Prognosis of Patients with Pancreatic Ductal Adenocarcinoma.

The aim of this study was to investigate the expression of Delta-like ligand 4(DLL4) and Endoglin(CD105) labeled microvessel density(MVD) in pancreatic ductal adenocarcinoma (PDAC) and evaluate their correlation with major clinicopathologic features and patients' survival. Forty-two pancreatic cancer and 20 normal pancreatic tissues were included in the study. Immunohistochemical staining was employed to assess the expression level of DLL4 both in tumor cells and stromal vascular endothelial cells, as well as CD105 which was used to determine MVD.

Influence of hydrophobic residues on the binding of CB[7] toward diammonium ions of common ammonium···ammonium distance.

We report the binding constants of CB[7] toward a series of naphthalene diammonium and 4,4'-dipiperidinium derivatives and compare the results with those obtained previously for CB[7]·3b by (1)H NMR and X-ray crystallography. The nature of binding in the host·guest complexes was investigated using quantum mechanical tools.

A modified Jarnagin-Blumgart classification better predicts survival for resectable hilar cholangiocarcinoma.

Background: Prediction of postoperative survival for hilar cholangiocarcinoma (HCCA) remains difficult although there have been a variety of clinical classification and staging systems. This study was designed to validate and compare some of the major HCCA staging systems in use today. In addition, we sought to build up a new staging system modified from Jarnagin-Blumgart (J-B) classification for HCCA, to predict survival better.

miR-211 suppresses hepatocellular carcinoma by downregulating SATB2.

Dysregulation of microRNAs (miRs) is involved in carcinogenesis. Deregulation of miR-211 has recently been observed in many tumors, but its function in hepatocellular carcinoma (HCC) is still unknown. Here we found that miR-211 was decreased in HCC cancer tissues compared with adjacent normal tissues.

A large inflammatory myofibroblastic tumor involving both stomach and spleen: A case report and review of the literature.

Inflammatory myofibroblastic tumor (IMT) is a rare, benign neoplasm that most commonly occurs in pediatric patients; it has been described as a pseudosarcomatous proliferation of spindled myofibroblasts mixed with lymphoplasmacytic cells. IMT has been reported in a number of locations throughout the body; however, cases occurring in the gastrointestinal tract are rare and to date, no case involving both the stomach and spleen has been reported. The current study presents a case of an extremely large IMT invading both the stomach and spleen in a 50-year-old female, presenting with a three-month history of left-sided abdominal distension without abdominal pain, fever or vomiting.

PRKCH 1425G/A Polymorphism Predicts Recurrence of Ischemic Stroke in a Chinese Population.

A recent genome-wide association study (GWAS) identified a nonsynonymous SNP (1425G/A) in PRKCH which was associated with increased risk of ischemic stroke. The purpose of this study was to examine whether this functional polymorphism is associated with stroke onset and prognosis in a Chinese population. We genotyped PRKCH 1425G/A using Improved Multiple Ligase Detection Reaction in 919 patients with ischemic stroke.

LRRK2 overexpression alters glutamatergic presynaptic plasticity, striatal dopamine tone, postsynaptic signal transduction, motor activity and memory.

Mutations in leucine-rich repeat kinase 2 (Lrrk2) are the most common genetic cause of Parkinson's disease (PD), a neurodegenerative disorder affecting 1-2% of those >65 years old. The neurophysiology of LRRK2 remains largely elusive, although protein loss suggests a role in glutamatergic synapse transmission and overexpression studies show altered dopamine release in aged mice. We show that glutamate transmission is unaltered onto striatal projection neurons (SPNs) of adult LRRK2 knockout mice and that adult animals exhibit no detectable cognitive or motor deficits.

Cucurbit[6]uril-cucurbit[7]uril heterodimer promotes controlled self-assembly of supramolecular networks and supramolecular micelles by self-sorting of amphiphilic guests.

We report the synthesis of cucurbit[6]uril–cucurbit[7]uril heterodimer (1) by click chemistry of monofunctionalized CB[6] and CB[7] derivatives. Combinations of 1 with hydrophobic guest 4b or hydrophilic polymeric guests 5b and 5c deliver hydrophobic or amphiphilic supramolecular block copolymers which form supramolecular networks (6) and supramolecular micelles (7), respectively, in the solid state.

Synaptic function is modulated by LRRK2 and glutamate release is increased in cortical neurons of G2019S LRRK2 knock-in mice.

Mutations in Leucine-Rich Repeat Kinase-2 (LRRK2) result in familial Parkinson's disease and the G2019S mutation alone accounts for up to 30% in some ethnicities. Despite this, the function of LRRK2 is largely undetermined although evidence suggests roles in phosphorylation, protein interactions, autophagy and endocytosis. Emerging reports link loss of LRRK2 to altered synaptic transmission, but the effects of the G2019S mutation upon synaptic release in mammalian neurons are unknown.

Pancreatic cancer derived exosomes regulate the expression of TLR4 in dendritic cells via miR-203.

MicroRNAs (miRNAs) are aberrant in many human tumors which can be transferred to immune cells by tumor-derived exosomes. Dendritic cells (DCs) play an important role in activation of immune response. However, the effect of tumor-derived exosomes on toll-like receptor (TLR) in DCs remains unclear.

Variant recurrent risk among stroke patients with different CYP2C19 phenotypes and treated with clopidogrel.

Polymorphisms of CYP2C19 have been associated with variant risk of subsequent cardiovascular events in survivors of myocardial infarction (MI) receiving clopidogrel. This study evaluated the impacts of CYP2C19 polymorphisms on stroke recurrence and other vascular events in a cohort of Chinese patients receiving clopidogrel. From Nanjing Stroke Registry Program, 625 consecutive patients with ischemic stroke were enrolled between May 2008 and April 2010.

Association analysis of genes in serotonin pathway with attention and executive function in patients with bipolar affective disorder.

Background: The reason why it is difficult to identify susceptibility genes attributed to bipolar disorder (BPD) is the phenotypic heterogeneity. The use of endophenotypes has been advocated as one possible strategy to discovery cause variants of BPD.

Methods: A total of 164 patients with BPD and 164 matched controls were employed in the present research.

Acute diffusion-weighted imaging lesion patterns predict progressive small subcortical infarct in the perforator territory of the middle cerebral artery.

Background: Single small subcortical infarct (SSSI) is generally considered to have a fair outcome. However, early neurological deterioration (END), a relatively unfavorable clinical course occurring during the acute phase of infarction, is not uncommon.

Aims: The aim of this study was to investigate the relationship between lesion patterns detected by diffusion-weighted imaging (DWI) and the presence of END in patients with acute SSSI in the perforator territory of the middle cerebral artery (MCA).

Association of heme oxygenase-1 gene rs2071746 polymorphism with vascular outcomes in patients with atherosclerotic stroke.

As an inducible isoform of heme oxygenase (HO), HO-1 was suggested to have an anti-oxidative stress, anti-inflammatory, anti-apoptotic and anti-proliferative effect. It was regarded as an important cytoprotective enzyme. We undertook this study to investigate whether HO-1 gene rs2071746 polymorphism was associated with clinical outcomes in atherosclerosis ischemic stroke patients.

Impacts of COX-1 gene polymorphisms on vascular outcomes in patients with ischemic stroke and treated with aspirin.

As the key point of function for aspirin to educe anti-platelet effects, cyclooxygenase-1 (COX-1) gene polymorphisms have long been suspected as a potential cause for aspirin nonresponsiveness. But this hypothesis has not been confirmed by large longitudinal studies. This study prospectively evaluated the impacts of COX-1 gene polymorphisms on stroke recurrence and other vascular events in a large cohort of Chinese patients with ischemic stroke and treated with aspirin.
