Multi-crystalline N-doped Cu/CuO/C foam catalyst derived from alkaline N-coordinated HKUST-1/CMC for enhanced 4-nitrophenol reduction.

Multi-crystalline N-doped Cu/CuO/C foam catalysts are successfully synthesized from N-coordinated HKUST-1/cellulose and applied in 4-nitrophenol (4-NP) reduction. Effects of N content and basicity on Cu morphology, crystal lattice and size, component dispersion and oxidation states in catalysts are systematically investigated. Moreover, transforming powder catalysts to foam morphology is proposed to further enhance catalytic performance and facilitate more feasible industrial applications.

[Changes of hair papilla and its role in the growth cycle of the hair follicles].

Objective: To investigate the changes of hair dermal papilla and its regulatory role in the growth cycle of the hair follicles.

Methods: Single hair follicles were isolated from surgical specimens of human scalp and cultured in Williams E medium. The growth of the hair follicle was measured and the morphology and structure of the dermal papilla in the different growth cycles were observed continuously.

Angiotensin II regulates phosphoinositide 3 kinase/Akt cascade via a negative crosstalk between AT1 and AT2 receptors in skin fibroblasts of human hypertrophic scars.

Angiotensin II (Ang II) stimulation has been shown to regulate proliferation of skin fibroblasts and production of extracellular matrix, which are very important process in skin wound healing and scarring; however, the signaling pathways involved in this process, especially in humans, are less explored. In the present study, we used skin fibroblasts of human hypertrophic scar, which expressed both AT1 and AT2 receptors, and observed that Ang II increased Akt phosphorylation and phosphoinositide 3 kinase (PI 3-K) activity. In addition, the Ang II-induced Akt phosphorylation was blocked by wortmannin, a PI 3-K inhibitor.

[Study on corelation between InsP(3) generation and TCR/ CD3 complex-mediated [Ca(2+)]i responses in T cells from SLE patients].

Aim: To demonstrate whether function disorder of T cells from SLE patients was relative to abnormal biochemical pathways mediated by TCR/ CD3 complex and whether this abnormality was relative to the InsP(3) production.

Methods: Human T cells were isolated through Nylon-columns from heparinized peripheral blood from SLE patients and control individuals. Percentage of CD3(+) T cells was detected by flow cytometry.

Analysis of clinical and immunological features of patients with systemic lupus erythematosus complicated by hepatitis C virus infection.

Objective: To investigate the prevalence and clinical significance of hepatitis C virus (HCV) infection in patients with systemic lupus erythematosus (SLE).

Methods: Serodiagnosis was conducted in 134 SLE patients and 200 volunteer blood donors to examine the antibodies of HCV with enzyme-linked immunosorbent assay-3 (ELISA-3). Recombinant immunoblot assay-3 (RIBA-3) and PCR were performed to verify the results.
