Developing cost-effective cocatalyst-modified photocatalytic systems with boosted carrier separation and rapid surface catalytic reaction is an ideal strategy for effectively converting solar energy into desired fuels. Herein, a series of CuS/MnCdS hierarchical heterostructures are designed and fabricated to achieve efficient and robust photocatalytic H evolution by coupling one-dimensional (1D) MnCdS nanorods with two-dimensional (2D) CuS nanosheets through a facile sonochemical strategy. Benefiting from dimensionality and cocatalyst effects, the constructed 2D/1D CuS/MnCdS heterojunction photocatalyst containing 1.

Methods: This study was performed on formalin-fixed paraffin-embedded resected specimens obtained from 112 patients with colorectal cancer. The expression level of ADAMTS12 was investigated by immunohistochemical staining to assess the relationship between ADAMTS12 expression and the clinicopathologic factors and to study the prognostic significance of ADAMTS12 in colorectal cancer patients.

Objective: To investigate the effects of the novel proteasome subunit Adrm1 knockdown by RNA interference on proliferation of colorectal cancer cells.
Methods: The shRNA eukaryotic expression vector against Adrm1 was constructed and transfected into colon cancer RKO cells. The Adrm1-shRNA stable transfected clones were selected.
This study investigated the role of transforming growth factor-beta1 (TGF-beta1)/Smads signaling in the alterations of lung structure and the effect of the exogenous decorin on lung structure modification in streptozotocin (STZ)-induced diabetic rats. Seventy-two Sprague-Dawley rats were evenly divided into four groups: STZ-induced diabetic rats (diabetic control), decorin adenovirus vector (Ad)-treated STZ rats (Ad-DCN), Ad-lacZ-treated STZ rats (Ad-lacZ), and normal controls. At 8, 16, and 28 weeks after STZ treatment, haematoxylin-eosin (H&E) and Masson's trichrome staining were performed to investigate the histological changes of diabetic lungs; Expressions of TGF-beta1 and collagen type IV in the diabetic lung were measured by Western blot and immunohistochemistry.

Recently, we reported that proteasome subunit PSMA7 located on 20q13 amplicon was overexpressed and associated with liver metastasis of colorectal cancer. The results indicate that PSMA7 may play an important role in the colorectal cancer progression and provide a unique target site for the development of therapeutic drugs.

Methods: To identify the PSMA7 protein expression in 62 primary site colorectal cancers, 34 lymph node metastatic sites and 13 liver metastatic sites by immunohistochemistry and clarify the correlation of its expression with the clinicopathological parameters.
Results: High expression of PSMA7 was detected in 38.
The proteasome subunit PSMA7 located on the 20q13 amplicon was found to be differentially expressed in colorectal cancer by semiquantitative RT-PCR. PSMA7 mRNA was overexpressed in 37.5% (12/32) colorectal cancer tissues while it was either of a low level or not expressed in matched normal mucosa.
