Motivating Inert Strontium Manganate with Iridium Dopants as Efficient Electrocatalysts for Oxygen Evolution in Acidic Electrolyte.

The search for high-performance and low-cost electrocatalysts in acid conditions still remains a challenging target. Herein, iridium (Ir) doped strontium manganate (named as Ir -SMO) is proposed as an efficient and durable low-iridium electrocatalyst for water oxidation in acidic media. The Ir -SMO with 75% less iridium in comparison to that of iridium dioxide (IrO ) exhibits excellent performance for oxygen evolution reaction (OER), which is even better than most of the iridium-based oxide electrocatalysts.

Optimization of Process Parameters for ESR Waspaloy Superalloy by Numerical Simulation.

A transient numerical simulation method is used to investigate the temperature field, velocity field, and solidified field of large-size Waspaloy superalloy during the electroslag remelting (ESR) process. The effects of melting rate, filling rate, and thickness of the slag layer on the molten pool shape and dendrite arm spacing evolution have been discussed. The temperature in the slag pool is high and relatively uniformly distributed, the temperature range is 1690-1830 K.

A Meta-Analysis of Erectile Dysfunction and Alcohol Consumption.

Purpose: The purpose of the study was to evaluate the association between alcohol consumption and risk of erectile dysfunction (ED).

Methods: PubMed was searched for reports published before June 2019. Data were extracted and combined odds ratios (ORs) calculated with random-effects models.

Cognitive control related network analysis: A novel way to measure neuron fiber connection of Alzheimer's disease.

Effective measurement of cognitive impairment caused by Alzheimer's disease (AD) will provide a chance for early medical intervention and delay the disease onset. Diffusion tensor imaging (DTI) provides a non-intrusive examination of cranial nerve diseases which can help us observe the microstructure of neuron fibers. Cognitive control network (CCN) consists of the brain regions that highly related to human self-control.

A study of feature extraction for Alzheimer's disease based on resting-state fMRI.

The Alzheimer's Disease (AD) has become a major threat of human health with its incidence rate ascending year by year. Early diagnosis of AD is very important for AD patients to keep life quality. The resting-state fMRI (rs-fMRI) which precisely reflects the brain changes on the resting state of individuals provides a quantitative approach, which has been introduced to distinguish AD patients from normal population.

Structural changes of cingulate cortex in post stroke depression.

Disruption of neural connections among regions regulating mood and cognition rather than cerebrovascular lesions may contribute to post-stroke depression (PSD). In this paper, we hypothesized that structural abnormalities in white matter structure like cingulate cortex induced by focal infarcts would play a role in mood regulation or depression after stroke onset. Various DTI coefficients including FA, RD and ADC with multiple signal distribution measurements were collected and statistically analyzed.

Predictive value of cystic fibrosis transmembrane conductance regulator (CFTR) in the diagnosis of gastric cancer.

Purpose: Gastric cancer is associated with poor prognosis. The high mortality rate of gastric cancer is mainly attributed to late detection, so diagnosis and treatment are crucial to decreasing mortality. The purpose of this study was to examine the predictive accuracy and discriminative ability of cystic fibrosis transmembrane conductance regulator (CFTR) in gastric cancer patients, in addition to the classical cancer tumor biomarkers carbohydrate antigen 199 (CA199) and carcinoembryonic antigen (CEA).

Clinical significance of autophagic protein LC3 levels and its correlation with XIAP expression in hepatocellular carcinoma.

Autophagy is a cellular recycling process to enable cell survival in less favorable conditions through degradation of their unnecessary cellular components and utilization of the breakdown components. Autophagy also plays an important role in tumor pathology. In this study, we detected autophagy protein light chain 3 (LC3) and X-linked inhibitor of apoptosis protein (XIAP) in hepatocellular carcinoma (HCC) tissue specimens to assess their role in HCC tumorigenesis and progression.

Loss of suppressors of cytokine signaling 3 promotes aggressiveness in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common cancers with a high mortality rate. Constitutive activation of STAT3 is found in various types of tumors, including HCC. In addition, suppressors of cytokine signaling 3 (SOCS3) signals for negative feedback to STATs, and is found to be inversely correlated with STAT3 expression.

Immunoproteomic to identify antigens in the intestinal mucosa of Crohn's disease patients.

Incidences of Crohn disease (CD) have increased significantly in the last decade. Immunoproteomics are a promising method to identify biomarkers of different diseases. In the present study, we used immunoproteomics to study proteins of intestinal mucosal lesions and neighboring normal intestinal mucosa of 8 CD patients.

Association of CDKN1B gene polymorphisms with susceptibility to breast cancer: a meta-analysis.

A number of case–control studies have been conducted to investigate the association of CDKN1B gene polymorphisms with breast cancer. However, these studies reported conflicting results. The aim of our study was to quantitatively summarize the association of CDKN1B gene polymorphisms with breast cancer.

[Clinical features and therapeutic strategies of acute appendicitis after radical gastrectomy for gastric carcinoma].

Objective: To explore the clinical characteristic and therapeutic strategies of acute appendicitis after radical gastrectomy for gastric carcinoma.

Methods: The clinical data of 31 patients with acute appendicitis after radical gastrectomy for gastric carcinoma from January 2006 to January 2012 was analyzed retrospectively. The profiles of previous operations, symptoms, physical signs, disease duration, progression time, examination results, peri-operative complications, results of bacterial culture and use of antibiotics were used to evaluate the clinical characteristics and therapeutic strategies.

Antiviral therapy and outcomes of patients with pneumonia caused by influenza A pandemic (H1N1) virus.

Background: There is limited data on the clinical outcome of patients with pandemic H1N1 (pH1N1) pneumonia who received oseltamivir treatment, especially when the treatment was administered more than 48 hours after symptom onset.

Methods: During the pandemic in 2009, a cohort of pH1N1 influenza pneumonia was built in China, and their clinical information was collected systematically, and analyzed with Cox models.

Results: 920 adults and 541 children with pneumonia who didn't receive corticosteroids were analyzed.

Comparative proteomic studies of serum from patients with hepatocellular carcinoma.

Background: Human hepatocellular carcinoma (HCC) is one of the most common solid tumors. It is always associated with prolonged hospital stay, increased attributable mortality, and greater hospitalization cost. To identify new biomarkers that could improve the early diagnosis in hepatocellular carcinoma, we performed a proteomic study.

STAT3 activation in monocytes accelerates liver cancer progression.

Background: Signal transducer and activator of transcription 3 (STAT3) is an important transcription factor ubiquitously expressed in different cell types. STAT3 plays an essential role in cell survival, proliferation, and differentiation. Aberrantly hyper-activated STAT3 signaling in cancer cells and in the tumor microenvironment has been detected in a wide variety of human cancers and is considered an important factor for cancer initiation, development, and progression.

Prognostic significance of phosphorylated signal transducer and activator of transcription 3 and suppressor of cytokine signaling 3 expression in hepatocellular carcinoma.

Altered expression of phosphorylated signal transducer and activator of transcription 3 (pSTAT3) and suppressor of cytokine signaling 3 (SOCS3) has been implicated in various types of human cancers. However, the clinical role of pSTAT3 and SOCS3 in hepatocellular carcinoma (HCC) is not well established. Immunohistochemical analysis of pSTAT3, SOCS3, Ki67 and VEGF expression was performed on tissue microarrays from 138 HCC patients.
