A λ-MnO2 supported Pt nanocatalyst（5 wt.% Pt/λ-MnO2） was synthesized using a facile approach.X-ray diffraction（XRD）, X-ray photoelectron spectroscopy（XPS）, scanning electronic microscope（SEM）, transmission electron microscopy（TEM）, and energy disperse spectroscopy（EDS） were used for catalyst structure and morphology characterization, which showed that the metallic Pt particles were attached on a λ-MnO2 surface through the interaction between Pt and λ-*** voltammetry（CV） was used to test the catalytic activity of Pt/λ-MnO2 toward methanol oxidation, which showed that Pt/λ-MnO2 catalyst has much higher catalytic activity than baseline Pt/C catalyst.

Metastases to the breast from extramammary neoplasms are very rare, constituting 2.7% of all malignant breast tumours. The most common primary tumor metastatic to the breast is primary breast cancer. Rectal cancer metastasizing to the breast is extremely rare. We report a case of aggressive rectal carcinoma with metastasis to the breast.

AIM: To investigate the anti-fibrosis effect of IκB kinase-beta inhibitor (IKK2 inhibitor IMD0354) in liver fibrosis. METHODS: Twenty male C57BL6 mice were divided into four groups. Five high-fat fed mice were injected with lipopolysaccharide (LPS, 10 mg/kg) intraperitoneally and five high-fat fed mice were without LPS injection to build models of liver injury, and the intervention group (five mice) was injected intraperitoneally with IKK2 inhibitor (IMD 30 mg/kg for 14 d), while the remaining five mice received a normal diet as controls. Hepatic function, pathological evaluation and liver interleukin-6 (IL-6) expression were examined. Western blotting and real-time polymerase chain reaction were used to detect the expressions of nuclear factor-κB (NF-κB), alpha-smooth muscle actin (α-SMA), tumor growth factor-beta1 (TGF-β1), tumor necrosis factor-alpha (TNF-α), typeⅠand type Ⅲ collagen proteins and mRNA. RESULTS: A mouse model of liver injury was successfully established, and IMD decreased nuclear transloca-tion of NF-κB p65 in liver cells. In the IMD-treated group, the levels of alanine aminotransferase (103 ± 9.77 μ/L vs 62.4 ± 7.90 μ/L, P liorated.

G-quadruplexes （G4s） play important roles in biological systems, such as telomere maintenance, replication, and transcription. Based on the DNA sequence, loop geometry, and the local environments, G4s can be classified into different conformations. It is important to detect different types of G4s to monitor the diseases related with G4s. Most ligands bind to G4s based on end-stacking modes, while rare ligands bind to G4s through groove binding modes. We have found that a cyanine dye DMSB interacts with parallel G4 by end-stacking and groove simultaneous binding mode. In this article, we found that DMSB could simply discriminate parallel G4s from other DNA motifs by using UV-vis spectrum. These results give some clues to develop high specificity G4 probes.

Objective To evaluate the efficacy and safety of combination chemotherapy with paclitaxel and carboplatin for advanced breast cancer (ABC). Methods From January 2001 to March 2006, 45 patients with ABC were treated with combination chemotherapy of paclitaxel and carboplatin. Patients received infusion of paclitaxel 175 mg/m2 on day 1 every 3 weeks or 75 mg/m2 on day 1, 8, 15 every 4 weeks. Carboplatin was administrated on day 2 with a dose of area under the time-concentration curve (AUC) being 5. Results The median number of cycles was 3 (range, 2-6). The overall response rate was 62.2%. Median time to progression was 7.0 months (95%CI:5.1-8.9). Median overall survival was 29.0 months (95%CI: 20.1-37.9). One year survival rate was 73.3%. Response rate for first line and second line treatment were 62.1% and 62.5%, respectively. No significant difference in response existed between visceral metastasis and soft tissue metastasis. The main side effects included nausea/vomiting, neurotoxicity, and hematologic toxicities. Grade Ⅲ to Ⅳ adverse events included nausea/vomiting in 2 cases (4.4%), leukopenia in 17 cases (37.8%), and alopecia in 6 cases (13.3%). Conclusion Combination of paclitaxel and carboplatin is active in treatment of ABC with an acceptable toxicity profile.

This article discusses the result of cognitive deviation originating from the lexical and syntactic difference between English and Chinese. By analyzing three different aspects involved in this paper, namely, synthetic versus analytic, compact versus diffusive and hypotactic versus paratactic deviations, a conclusion can be drawn that consciousness of necessary information qualifies a translator for work only when he is familiar with this kind of cognitive deviation.

Test power of VLSI systems has become a challenging issue *** scan shift power dominates the average test power and restricts clock frequency of the shift phase,leading to excessive thermal accumulation and long test *** paper proposes a scan chain design technique to solve the above *** on weighted transition metric (WTM),the proposed extended WTM (EWTM) that is utilized to guide the scan chain design algorithm can estimate the scan shift power in both the shift-in and shift-out ***,the wire length overhead of the proposed scan chain design can also be reduced by the proposed distance of EWTM (DEWTM) *** results confirm that the proposed approach can significantly reduce scan shift power with low wire length overhead.
