Effect of Alloying Elements on the High-Temperature Yielding Behavior of Multicomponent γ'-L1 Alloys.

The exceptional mechanical properties of Ni-based high entropy alloys are due to the presence of ordered L1 (γ') precipitates embedded within a disordered matrix phase. While the strengthening contribution of the γ' phase is generally accepted, there is no consensus on the precise contribution of the individual strengthening mechanisms to the overall strength. In addition, changes in alloy composition influence several different mechanisms, making the assessment of alloying conditions complex.

Acidic Microenvironment Up-Regulates Exosomal miR-21 and miR-10b in Early-Stage Hepatocellular Carcinoma to Promote Cancer Cell Proliferation and Metastasis.

The incidence of hepatocellular carcinoma is rising worldwide. It is predicted that nearly half of the early-stage hepatocellular carcinoma (E-HCC) patients will develop recurrence. Dysregulated pH, a hallmark of E-HCC, is correlated with poor prognosis.

FMNL1 mediates nasopharyngeal carcinoma cell aggressiveness by epigenetically upregulating MTA1.

It has been suggested that formin-like protein 1 (FMNL1) plays an important role in the pathogenic process of several hematopoietic malignancies. In this study, we performed a series of in vivo and in vitro assays to elucidate the biological functions of FMNL1 and underlying mechanisms in human nasopharyngeal carcinoma (NPC) pathogenesis. Herein, we report that high expression of FMNL1 in NPC is positively associated with an aggressive disease and/or poor patient survival.

LINC01410-miR-532-NCF2-NF-kB feedback loop promotes gastric cancer angiogenesis and metastasis.

Dysregulation of non-coding RNAs, including miRNAs and lncRNAs has been reported to play vital roles in gastric cancer (GC) carcinogenesis, but the mechanism involved is largely unknown. Using the cancer genome atlas (TCGA) data set and bioinformatics analyses, we identified miR-532-5p as a potential tumor suppressor in GC, and found that lncRNA LINC01410 might be a negative regulator of miR-532-5p. We then conducted a series of in vivo and in vitro assays to explore the effect of LINC01410 on miR-532-5p-mediated GC malignancy and the underlying mechanism involved.

AGBL2 promotes cancer cell growth through IRGM-regulated autophagy and enhanced Aurora A activity in hepatocellular carcinoma.

AGBL2 has been reported to catalyze α-tubulin detyrosination, by which it promotes tumorigenesis and cancer progression. However, its potential role in the pathogenesis of hepatocellular carcinoma (HCC) has not been revealed yet. In the present study, AGBL2 was frequently found being overexpressed in HCC tissues and cell lines.

Eukaryotic Initiation Factor 5A2 Contributes to the Maintenance of CD133(+) Hepatocellular Carcinoma Cells via the c-Myc/microRNA-29b Axis.

Cancer stem cells (CSCs)/cancer-initiating cells (CICs) are suggested responsible for driving cancer resistance to conventional therapies and for cancer recurrence and/or metastasis. CD133 is served as a key biomarker to identify and characterize this subpopulation of cells in hepatocellular carcinoma (HCC). Our previous study indicated that overexpression of eukaryotic initiation factor 5A2 (EIF5A2) promotes HCC cell metastasis and angiogenesis.

Haemorrhagic shearing lesions associated with diffuse axonal injury: application of T2 star-weighted angiography sequence in the detection and clinical correlation.

Purpose: To assess the diagnostic value of T2 star-weighted angiography (SWAN) sequence for diffuse axonal injury (DAI) by virtue of correlation analysis between the number, volume and regional distribution of haemorrhagic lesions determined with SWAN sequence and clinical variables.

Methods: Twenty-eight DAI patients were included in our study and were divided into subgroups in compliance with dichotomized clinical variables separately. Global and regional number, volume and distribution of haemorrhagic lesions were compared between groups by non-parametric Mann-Whitney U test (two tailed) and independent samples t test.

Z-ligustilide extracted from Radix Angelica Sinensis decreased platelet aggregation induced by ADP ex vivo and arterio-venous shunt thrombosis in vivo in rats.

Antithrombotic therapy has become an important goal for the treatment of ischemic disorders such as cerebral ischemia. Our recent studies found that Z-ligustilide (LIG), a characterized 3-n-alkylphthalide constituent of Radix Angelica sinensis essential oil, exerted significant neuroprotection against cerebral ischemic damage in several animal models. The present study evaluated the antithrombotic activity of LIG and its effect on platelet aggregation and coagulation time.

Protection against hydrogen peroxide-induced injury by Z-ligustilide in PC12 cells.

Z-ligustilide (Z-LIG) is the primary lipophilic compound of the Chinese medicine Danggui (Radix Angelica sinensis). Previous studies demonstrated that Z-LIG had significant neuroprotective potential in both transient and permanent cerebral ischemia, possibly through antioxidant and anti-apoptotic mechanisms. The present study examined the mechanisms of Z-LIG on hydrogen peroxide (H(2)O(2))-induced injury in PC12 cells.

Neuroprotective effect of Z-ligustilide against permanent focal ischemic damage in rats.

The present study investigated the effect of Z-Ligustilide (LIG), a characterized 3-n-alkyphthalide derivative existed in many medical Umbelliferae plants, on permanent focal ischemic brain injury in rats. Focal cerebral ischemia was induced by the occlusion of middle cerebral artery (MCA) for 24 h. LIG (20, or 80 mg/kg), orally administered at 2 h after ischemia, reduced the cerebral infarct volumes by 48.
