Triple network hydrogels (TN gels) prepared by a one-pot, two-step method with high mechanical properties.

In this work, poly(vinyl alcohol) (PVA) was incorporated into the networks of polyacrylamide/polyacrylic acid (PAM/PAA) to prepare novel PAM/PAA/PVA Triple-network (TN) hydrogels by an polymerization and repeated freezing-thawing (F-T) process. The TN hydrogels have not only high mechanical strength, but also a moderate swelling ability by varying the weight ratio of calcium chloride (CaCl) and PVA and free shaping. The compressive stress of the as-prepared hydrogels could reach 11 MPa, and the highest stretching stress could reach 0.

Effect of OH on chemical mechanical polishing of β-GaO (100) substrate using an alkaline slurry.

β-GaO, a semiconductor material, has attracted considerable attention given its potential applications in high-power devices, such as high-performance field-effect transistors. For decades, β-GaO has been processed through chemical mechanical polishing (CMP). Nevertheless, the understanding of the effect of OH on β-GaO processed through CMP with an alkaline slurry remains limited.

A small molecule targeting glutathione activates Nrf2 and inhibits cancer cell growth through promoting Keap-1 -glutathionylation and inducing apoptosis.

The level of glutathione (GSH) is increased in many cancer cells. Consuming intracellular GSH by chemical small molecules that specifically target GSH is a new strategy to treat cancer. Recently, we synthesized and proved that a new compound 2-(7-(diethylamino)-2-oxo-2-chromen-3-yl)cyclohexa-2,5-diene-1,4-dione (PBQC) could target to and consume intracellular GSH specifically, but, it is not clear if PBQC can affect cancer cell growth and the activity of the nuclear factor-erythroid 2-related factor 2 (Nrf2) which is a key factor involved in regulation of cancer cell growth.

Experimental and theoretical calculation investigation of 2,4-dichlorophenoxyacetic acid adsorption onto core-shell carbon microspheres@layered double hydroxide composites.

Layered double hydroxides (LDHs) usually aggregate irregularly and hardly redisperse in water. Moreover, the affinity of LDHs is poor for organic compounds. In this study, three different core-shell composites, CMS@MgAl-LDH, CMS@NiAl-LDH, and CMS@ZnAl-LDH, were synthesized by direct fabrication of LDH nanoplatelets onto carbon microspheres (CMS) for the removal of the adsorbed 2,4-dichlorophenoxyacetic acid (2,4-D).

Photocatalytic Overall Water Splitting over MIL-125(Ti) upon CoPi and Pt Co-catalyst Deposition.

Photocatalytic overall water splitting is realized by taking advantage of the semiconductive and porous properties of MIL-125(Ti). CoPi and Pt are deposited into MIL-125(Ti) in two steps. The co-catalysts CoPi and Pt not only act as reactive sites for oxygen and hydrogen evolution, respectively, but also improve the photogenerated charge separation efficiency.

Outcome of radiofrequency ablation over partial nephrectomy for small renal mass (<4 cm): a systematic review and meta-analysis.

Objective: A meta-analysis was undertaken to provide evidence-based clinical trials comparing radiofrequency ablation with partial nephrectomy for small renal mass.

Methods: We searched through the major medical databases such as Pub Med, EMBASE, Medline, Science Citation Index, Web of Science and CNKI (Chinese National Knowledge Infrastructure Database) and Wangfang (Database of Chinese Ministry of Science & Technology) for all published studies without any limit on language from May 2007 until May 2015. The following search terms wereused: partial nephrectomy, radiofrequency ablation, renal cell carcinoma, small renal tumor or mass.

Efficacy of medical thoracoscopic talc pleurodesis in malignant pleural effusion caused by different types of tumors and different pathological classifications of lung cancer.

The aim of this study was to assess the efficacy and complications and compare the efficacy of medical thoracoscopic talc pleurodesis among patients with different types of tumors and different pathological classifications of lung cancer as well as to evaluate the role of postoperative negative pressure chest tube drainage. A total of 1061 patients with malignant pleural effusion who underwent thoracoscopic pleurodesis were analyzed retrospectively. The complications, postoperative drainage time, and efficacy of pleurodesis among patients with different types of tumors and different pathological classifications of lung cancer were assessed.

Inhibition of microRNA-1 attenuates hypoxia/re-oxygenation-induced apoptosis of cardiomyocytes by directly targeting Bcl-2 but not GADD45Beta.

MicroRNAs are small non-coding RNAs that are able to regulate gene expression and play important roles in some biological and pathological processes, including the myocardial ischemia/reperfusion (I/R) injury. Recent findings demonstrated that miR-1 exacerbated I/R-induced injury. This study was to investigate theanti-apoptotic property of miR-1 inhibition and the potential regulatory mechanism.

Diffuse mesangial and endocapillary cell proliferative glomerulonephritis with persistent hypocomplementemia in a child.

A 15-year-old boy was admitted to People's Hospital of Dong E with anasarca. The laboratory findings revealed proteinuria, hematuria, hypocomplementemia. Renal biopsy specimen revealed diffuse mesangial and endocapillary cell proliferative glomerulonephritis on light microscopic (LM) examination.

Sphingosylphosphorylcholine in cancer progress.

Sphingosylphosphorylcholine (SPC) is a naturally occurring bioactive sphingolipid in blood plasma, metabolizing from the hydrolysis of the membrane sphingolipid. It has been shown to exert multifunctional role in cell physiological regulation either as an intracellular second messenger or as an extracellular agent through G protein coupled receptors (GPCRs). Because of elevated levels of SPC in malicious ascites of patients with cancer, the role of SPC in tumor progression has prompted wide interest.

Effect of supersaturation on hillock of directional Growth of KDP crystals.

KDP single crystals were grown in aqueous solution by using "point seeds" with a defined crystallographic direction of 59° to the Z axis. When hillock slopes on the (100) face of KDP crystals were measured within the supersaturation (σ) range of 0 < σ ≤ 0.06, the slope of hillocks with hollow cores depended nonlinearly on supersaturation.

Blocking TRAIL-DR5 signaling with soluble DR5 alleviates acute kidney injury in a severely burned mouse model.

Acute kidney injury (AKI) predicts high mortality in severely burned patients. Apoptosis plays a significant role during AKI; however, the apoptotic mechanisms underlying AKI induced by burn injury are not clear. Here, we report a critical role for tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-Death receptor 5 (DR5) signaling in the pathogenesis of AKI.

[Searching for dwarf nova candidates with automatic methods in massive spectra].

In the present paper, an automatic and efficient method for searching for dwarf nova candidates is presented. The methods PCA (principal component analysis) and SVM (support vector machine) are applied in the newly released SDSS-DR9 spectra. The final dimensions of the feature space are determined by the identification accuracy of training samples with different dimensions constrained by SVM.

Adsorption of ammonium and phosphate by feather protein based semi-interpenetrating polymer networks hydrogel as a controlled-release fertilizer.

A new feather protein-grafted poly(potassium acrylate)/polyvinyl alcohol (FP-g-PKA/PVA) semi-interpenetrating polymer networks (semi-IPNs) hydrogel was produced through graft copolymerization with FP as a basic macromolecular skeletal material, acrylic acid as a monomer and PVA as a semi-IPNs polymer. The adsorption of ammonium and phosphate ions from aqueous solution using the new hydrogel as N and P controlled-release fertilizer with water-retention capacity was studied. The effects of pH value, concentration, contact time and ion strength on NH4+ and PO3-4 removal by FP-g-PKA/PVA semi-IPNs hydrogel were investigated using batch adsorption experiments.
