A Comparative Study of Video-Assisted Thoracic Surgery with Thoracotomy for Middle Lobe Syndrome

right middle lobe or left lingular segment was defined as MLS Jian Li and Chengwu Liu have contributed equally to this study. [2]. Most patients with MLS would recover by applying antibiotics and

The coherent large-scale circulation change between dry/wet years over central eastern China simulated by NCAR CAM5

This study evaluates the simulation of the coherent circulation structure correspond to the changes of mid-summer (July–August) rainfall over eastern China (30°–40° N, 110°–120° E) in high-resolution NCAR CAM5. Forced by historical sea surface temperatures (SSTs), the NCAR CAM5 reasonably reproduces coherent changes of temperature and large-scale circulations, corresponding to the ...

The patterns and timing of recurrence after curative resection for gastric cancer in China

Background The recurrence of gastric cancer after curative resection had adverse effects on patients’ survival. The treatment presence varied from different countries. The aims of this study were to understand the recurrence incidence, patterns, and timing and to explore the risk factors in China. Methods One thousand three hundred four patients who undergoing curative resection ...

Size effect of Au/PAMAM contrast agent on CT imaging of reticuloendothelial system and tumor tissue

Polyamidoamine (PAMAM)-entrapped Au nanoparticles were synthesized with distinct sizes to figure out the size effect of Au-based contrast agent on CT imaging of passively targeted tissues. Au/PAMAM nanoparticles were first synthesized with narrow distribution of particles size of 22.2 ± 3.1, 54.2 ± 3.7, and 104.9 ± 4.7 nm in diameters. Size effect leads no significant difference on ...

New classification of lunate fossa fractures of the distal radius

Background A die-punch fracture is a depression fracture of the lunate fossa of the distal radius. We propose a morphological classification of die-punch fractures that includes five types: center depression fractures, vertical depression fractures, volar depression fractures, dorsal depression fractures, and double die-punch fractures. Methods The radiographs of 112 die-punch ...

Impact of moisture divergence on systematic errors in precipitation around the Tibetan Plateau in a general circulation model

Current state-of-the-art atmospheric general circulation models tend to strongly overestimate the amount of precipitation around steep mountains, which constitutes a stubborn systematic error that causes the climate drift and hinders the model performance. In this study, two contrasting model tests are performed to investigate the sensitivity of precipitation around steep slopes. ...

Mammary inflammatory gene expression was associated with reproductive stage and regulated by docosahexenoic acid: in vitro and in vivo studies

Background Periparturient mastitis is the most prevalent disease affecting lactating animals. However, it has long been relied on antibiotics to deal with mastitis, leading to a potential threat to food safety. This study was aimed to investigate the expression of pro-inflammatory cytokines in mammary glands of sows around parturition when mastitis and oxidative stress usually ...

CD147 promotes cell motility via upregulation of p190-B RhoGAP in hepatocellular carcinoma

Background The acquisition of inappropriate migratory feature is crucial for tumor metastasis. Rho-family GTPases including RhoA are molecular switches that play critical roles in regulating cell movement. We investigated the molecular mechanism underlying CD147 induced RhoA deactivation in hepatocellular carcinoma (HCC) cells. Methods Wound-healing assay was performed to study the ...

Coordination of supply chain with a dominant retailer under government price regulation by revenue sharing contracts

As the demands of some important products such as oil, gas, and agricultural commodities are disrupted, the government often regulates the retail price that includes impositions of a price ceiling and a price floor. In this paper, we analyze the coordination of a supply chain with a dominate retailer under the government price regulation policy by a revenue sharing contract after ...

Effort-reward imbalance and perceived quality of patient care: a cross-sectional study among physicians in Germany

Background Work stress may impair physicians’ ability to provide high quality patient care. Prior research remains however sparse and has insufficiently explored explanations for this relationship. It has been suggested that physicians’ poor mental health is one potential explanatory factor. We drew on a well-established model to measure work stress (the effort-reward imbalance ...

Improvement of sexual function in POEMS syndrome after combination therapy of Lenalidomide and dexamethasone

Background POEMS syndrome is a rare paraneoplastic syndrome due to an underlying plasma cell neoplasm. Hypogonadism is the most common endocrine abnormality in POEMS syndrome. There is no data about improvement of hypogonadism and sexual dysfunction after appropriate treatment of POEMS syndrome so far. In this single-center prospective study, the efficacy of low-dose lenalidomide ...

A microRNA molecular modeling extension for prediction of colorectal cancer treatment

Background Several studies show that the regulatory impact of microRNAs (miRNAs) is an essential contribution to the pathogenesis of colorectal cancer (CRC). The expression levels of diverse miRNAs are associated with specific clinical diagnoses and prognoses of CRC. However, this association reveals very little actionable information with regard to how or whether to treat a CRC ...

Impact of ambient fine particulate matter (PM 2.5 ) exposure on the risk of influenza-like-illness: a time-series analysis in Beijing, China

Background Air pollution in Beijing, especially PM 2.5 , has received increasing attention in the past years. Although exposure to PM 2.5 has been linked to many health issues, few studies have quantified the impact of PM 2.5 on the risk of influenza-like illness (ILI). The aim of our study is to investigate the association between daily PM 2.5 and ILI risk in Beijing, by means of ...
