We proposed a graphene based active plasmonic device by the introduction of graphene-MoS_(2) heterostructures. The device was composed of a monolayer MoS_(2) layer between the silicon substrate and periodically arranged graphene nanoribbon arrays. The finite-difference time domain(FDTD) method was used to analyze and compare the changes of the surface plasmon resonant wavelength and modulation depth(MD) in the two cases with and without MoS_(2). It was found that all the parameters of the width, period and Fermi level of the graphene nanoribbons affect the surface plasmon resonant wavelength of the plasmonic device. The introduction of the monolayer MoS_(2) can produce a redshift about 3 μm of the surface plasmon resonant wavelength, while the MD is basically unchanged. The redshift of the graphene surface plasmon resonant wavelength will provide application prospects for new active graphene plasmonic devices.

Sudden cardiac death(SCD)is the leading cause of death from out-of-hospital cardiovascular disease worldwide,with an annual incidence of 1.4 per 100,000 in females and 6.8 per 100,000 in males.1 Most cases of SCD in older patients(>45 years)are caused by atherosclerotic coronary artery *** in younger patients(<45 years)is caused by inherited cardiovascular diseases.

The thermolysis of urea-water solution and its product, HNCO hydrolysis is investigated in a dual-reactor system. For the thermal decomposition below about 1073 K, the main products are ammonia (NH3) and isocyanic acid (HNCO) whereas at higher temperatures the oxidation processes take effect and the products include a low concentration of nitric oxide (NO) and nitrous oxide (N2O). The gas HNCO is quite stable and a high yield of HNCO is observed. The ratio of NH3 to HNCO increases from approximately 1.2 to 1.7 with the temperature. The chemical analysis shows that H radical is in favor of HNCO hydrolysis by instigating the reaction HNCO+H·→·NH2+CO and high temperature has positive effect on H radical. The hydrolysis of HNCO over an alumina catalyst made using a sol-gel process (designated as γ-Al2O3) is investigated. The conversion of HNCO is high even at the high space velocities (6×105 h-1) and low temperatures (393–673 K) in the tests with catalysts, which enhances HNCO hydrolysis and raises the ratio of NH3 to HNCO to approximately 100. The pure γ-Al2O3 shows a better catalytic performance than CuO/γ-Al2O3. The addition of CuO not only reduces the surface area but also decreases the Lewis acid sites which are recognized to have a positive effect on the catalytic activity. The apparent activation energy of the hydrolysis reaction amounts to about 25 kJ/mol in 393–473 K while 13 kJ/mol over 473 K. The overall hydrolysis reaction rate on catalysts is mainly determined by external and internal mass-transfer limitations.

We proposed and demonstrated a wavelet transform modulus maxima （WTMM） de-noising method to decrease the temperature error. In this scheme, the composition scale was determined simply by the WTMM amplitude variation with the growth of the decomposition scale at 30 ℃, and the signal WTMM was obtained by the wavelet decomposition modulus on every decomposition scale based on the modulus propagating difference between the signal and noise. Then, we reconstructed the signal using the signal WTMM. Experimental results show that the proposed method is effective for de-noising, allowing for a temperature error decrease of about 1 ℃ at 40 ℃ and 50℃ comparing to the original data.

Prostate cancer is one of the most common malignancies in men. Previous research has determined that androgen deprivation therapy （ADT） may be accompanied by an unfavourable metabolic profile. In this prospective study, 133 men were recruited, including 46 prostate cancer patients who had undergone bilateral orchiectomy and been on flutamide （the ADT group）, 37 men with prostate cancer who had undergone radical prostatectomy （the non-ADT group） and 50 normal control subjects （the control group）. All subjects were followed for at least 12 months. From baseline to 3 months, men in the ADT group had increased levels of fasting serum insulin and low-density lipoprotein compared to the other two groups （P〈0.05）. No obvious changes were found in the other parameters （P〉0.05）. After 12 months, men in the ADT group had increased levels of waist circumference, fasting serum insulin and glucose, total cholesterol, high-density lipoprotein and low-density lipoprotein compared to the other two groups （P〈0.05）. Additionally, the morbidity rate of metabolic syndrome in the ADT group was higher （P〈0.05） compared to the other two groups. ADT through surgical castration for men with prostate cancer may be associated with unfavourable metabolic changes. The benefits of the therapy should be balanced prudently against these risks.

Background Hyperhomocysteine is an independent risk factor of coronary heart disease （CHD）. However, whether hyperhomocys teine affects the progression of atherosclerosis is unclear. In the present study, we examined the effect of hyperhomocysteine on the forma tion of atherosclerosis in low-density lipoprotein receptor-deficient （LDLr ） mice. Methods Forty-eight 7-week-old LDLr/ mice were assigned to the following groups： mice fed a standard rodent diet （control group）, mice fed a high-methionine diet （high-methionine group）, mice fed a high-fat diet （high-fat group）, and mice fed a diet high in both methionine and fat （high-methionine and high-fat group）. At the age of 19, 23, and 27 weeks, four mice at each interval in every group were sacrificed. Results At the end of the study, mice did not show atherosclerotic lesions in the aortic sinus and aortic surface until 27 weeks old in the control group. However, atherosclerotic lesions developed in the other three groups at 19 weeks. The amount of atherosclerotic lesions on the aortic surface was lower in the high-methionine group than in the high-fat group （P 〈 0.001）. Atherosclerotic lesions on the aortic surface in the high-methionine and high-fat group were the most severe. The mean area of atherosclerotic lesions in the aortic sinus compared with atherosclerotic lesions on the aortic surface was lower in the high-methionine group than in the high-fat group （P 〈 0.001）. Atherosclerotic lesions in the aortic sinus in the high-methionine and high-fat group were the most severe. Conclusions Homocysteinemia accelerates atherosclerotic lesions and induces early atherosclerosis independently in LDLrmice. Reducing the level of homocysteinemia may be beneficial for prevention and treatment of CHD.
