Injectable hydrogel harnessing foreskin mesenchymal stem cell-derived extracellular vesicles for treatment of chronic diabetic skin wounds.

Chronic skin wounds are a serious complication of diabetes with a high incidence rate, which can lead to disability or even death. Previous studies have shown that mesenchymal stem cells derived extracellular vesicles (EVs) have beneficial effects on wound healing. However, the human foreskin mesenchymal stem cell (FSMSCs)-derived extracellular vesicle (FM-EV) has not yet been isolated and characterized.

MicroRNA-495 Regulates Migration and Invasion in Prostate Cancer Cells Via Targeting Akt and mTOR Signaling.

Abnormal microRNA (miR) expressions were implicated in prostate cancer progression. We identified a novel miR-495, which was downregulated in prostate cancer, but not normal prostate cell lines. MiR-495 directly targeted the 3'-UTR of Akt and mTOR mRNAs.

Pemetrexed in treating patients with metastatic bladder cancer.

Background: This pooled analysis was conducted to evaluate the efficacy and safety of pemetrexed based chemotherapy in treating patients with metastatic bladder cancer as salvage chemotherapy.

Methods: Clinical studies evaluating the efficacy and safety of pemetrexed based regimens on response and safety for patients with bladder cancer were identified by using a predefined search strategy. Pooled response rate (RR) of treatment were calculated.

Characterization and photocatalytic property of Pd/TiO2 with the oxidation of gaseous benzene.

Increasing environmental pollution caused by the volatile organic compounds due to their toxicity is a matter of great concern. So it is crucial to develop processes which can destroy these compounds effectively. It has been found that the photocatalytic activity of TiO(2) towards the decomposition of gaseous benzene can be greatly enhanced by loading Pd on the surface of TiO(2).

Bis(2,3-dimethyl-butane-2,3-diamine)nickel(II) dinitrate monohydrate.

In the title compound, [Ni(C(6)H(16)N(2))(2)](NO(3))(2)·H(2)O, the bis-(2,3-dimethyl-butane-2,3-diamine)nickel(II) complex cation possesses a relatively undistorted square-planar geometry about the Ni atom, which lies on an inversion centre and is coordinated by four N atoms from two symmetry-related 2,3-diamino-2,3-dimethyl-butane (tmen) ligands. The amine groups are N-H⋯O hydrogen bonded to the nitrate anions, which are, in turn, linked by inter-stitial water mol-ecules lying on a twofold axis. The infinite zigzag chains thus formed along [001] are further connected to each other by N-H⋯O hydrogen bonds towards the water mol-ecules, forming layers of two-dimensional hydrogen-bonded arrays.

[Correlation between expression of metastasis-associated gene 1 and matrix metalloproteinase 9 and invasion and metastasis of breast cancer].

Objective: To investigate the expression of metastasis-associated gene 1 (MTA1) and matrix metalloproteinase 9 (MMP-9) gene in breast carcinoma and the relationship between the expression of these genes and the invasion of breast cancer.

Methods: Fluorescence quantitative PCR technique was used to detect the mRNA expression of MTA1 and MMP-9 gene among 56 human breast cancer samples.

Results: The mRNA expression rate of MTA1 was higher in 83.

[Diagnosis and treatment of breast lumps in children].

Objective: To summarize the diagnosis and treatment of breast lumps in children.

Methods: The clinical data of 61 children with breast lumps, 20 with physiological breast masses, 5 male and 15 female, aged 1 - 14, 38 with benign tumors, 1 male and 37 female, aged 10 - 14, 3 with malignant tumors, aged 7 months, and 10 and 13 years. diagnosed and treated 2001 - 2006 were analyzed.
