[Effects of warming on physicochemical property of branch and leaf litter in subtropical plantation].

At the regional scale, substrate properties are the key factors driving litter decomposition rate. In this study, soil temperature was increased by buried heating cables to explore the impacts of climate warming on the physical and chemical properties in branch and leaf of litter. The results showed that after 5 years of soil warming (4 ℃), the contents of nitrogen (N), phosphorus (P) and water-soluble substance in branch litter increased by 35.

[Value of Magnetic Resonance Imaging Findings in Differential Diagnosis between the Adult Reversible Splenial Lesion Syndrome and Ischemic Infarction of the Splenium of the Corpus Callosum].

Objective To evaluate the magnetic resonance imaging (MRI) findings in differential diagnosis between the adult reversible splenial lesion syndrome (RESLES) and ischemic infarction of the splenium of the corpus callosum (SCC). Methods The MRI findings and clinical data of 7 RESLES patients and 13 patients with ischemic infarction of SCC who were clinically diagnosed and treated in our center from May 2015 to June 2017 were analyzed retrospectively. The main MRI findings included location,morphology,signal intensity,maximum cross-sectional area,diffusion weighted imaging (DWI),and apparent diffusion coefficient (ADC) value.

MiR-410 inhibition induces HUVECs proliferation and represses ox-LDL-triggered apoptosis through activating STAT3.

Ox-LDL-induced endothelial cells injury has been reported to play an important role in the development of atherosclerosis (AS). MicroRNAs have been identified to regulate their target genes post-transcriptionally and they are able to participate in the various diseases, including AS. However, the role of miR-410 in ox-LDL-triggered abnormal function of endothelial cells remains to be elaborated.

[Correlations between apparent diffusion coefficient in diffusion?weighted magnetic resonance imaging and molecular subtypes of invasive breast cancer masses].

Objective: To study the correlation of apparent diffusion coefficient (ADC) measured by diffusion-weighted magnetic resonance imaging (MRI) with the molecular subtypes and biological prognostic factors of invasive breast cancer masses.

Methods: Breast MRI data (including dynamic enhanced and diffusion-weighted imaging) were collected from 64 patients with pathologically confirmed invasive breast cancer masses (a total of 69 lesions). The mean ADC values of the lesions were calculated and their correlations were analyzed with the 5 molecular subtypes of invasive breast cancer and the biological prognostic factors including estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor 2 (HER2), and Ki-67 index.

Tissue-specific metabolic responses of Cyprinus flammans to copper.

Copper (Cu) contamination is serious in China, with ≤2.76 mg/L in some waters. Exposure to Cu causes a high toxicity to the aquatic organisms and subsequent ecological risk.

Enhancement of the survival of engrafted mesenchymal stem cells in the ischemic heart by TNFR gene transfection.

Autologous or allogeneic mesenchymal stem cells (MSCs) have been used as one of the potential cell sources for cellular cardiomyoplasty. The adverse microenvironment in acute myocardial infarction, however, is considered a deleterious factor for MSC transplantation and cell survival. Tumor necrosis factor (TNF)-alpha is an inflammatory mediator produced during ischemia that may affect the survival of MSCs.

Anti-inflammation role for mesenchymal stem cells transplantation in myocardial infarction.

The aim of the present study was to investigate the role of anti-inflammation for MSCs transplantation in rat models of myocardial infarction. Rats with AMI induced by occlusion of the left coronary artery were randomized to MSCs transplantation group, MI group and sham operated group. The effects of MSCs transplantation on cardiac inflammation and left ventricular remodeling in non-infarcted zone were observed after 4 weeks of MI.
