Dear Editor,Allergic conjunctivitis is the most common ocular surface allergic disease, affecting more than 30% of the population[1-2]. In the immediate phase of the allergic reactions(type Ⅰ) in patients with seasonal allergic conjunctivitis(SAC), the binding of antigen with the reaginic antibody leads to the formation and release of chemical mediators, such as histamines, in the local anaphylactic reaction[3].

In this research a novel electrochemical system using dual boron-doped diamond (BDD) electrodes as the anode and cathode, for the first time, has been developed for CO_2 conversion and wastewater treatment in a synergetic and simultaneous process. On the BDD cathode CO_2 is converted into formaldehyde while in the anodic side organic wastes are decomposed on the BDD anode. Interestingly, when potassium hydrogen phthalate (KHP) was used as the organic model to be degraded in the anodic side, a higher efficiency of formaldehyde generation from CO_2 was observed on the BDD cathode. The enhanced effect of formaldehyde formation in the presence of KHP oxidation suggests that this novel electrochemical system can combine conversion of CO_2 to the form of high-value chemicals and wastewater purification in a simultaneous and harmonious process.

In nanocrystalline dye-sensitized solar cells (DSSCs) the absorption of a large fraction of the incident solar radiation is important for achieving high efficiencies. We develop a model to include both the optical process and the electrochemical process. This model allows us to calculate the performance of the different optical designs (for example the different scattering layers and the different reflecting plane). It is found that appropriate optical designs can improve the performance of DSSCs greatly.

AIM:To investigate the association between adiponectin levels and risk of colorectal adenoma and cancer (early and advanced).METHODS: A cross-sectional study in a cohort of hospital-based patients was conducted between January 2004 and March 2006 at Yamagata University Hospital. Male subjects, who had colorectal tumors detected by endoscopic examination, were enrolled according to inclusion and exclusion criteria. Based on the T factor of the TNM system, intraepithelial carcinoma and submucosally invasive carcinoma were def ined as early cancer, and invasion into the muscularis propria or deeper was defined as advanced cancer. The plasma levels of glucose, insulin, total cholesterol, triglyceride, high sensitivity C-reactive protein, insulin like growth factor (IGF)-1, IGF binding protein-3, adiponectin, leptin, and resistin were measured. Each factor level was designated low or high, and the risk of adenoma or cancer was estimated by univariate and multivariate logistic regression ***: We enrolled 124 male subjects (47 with adenoma, 34 with early cancer, 17 with advanced cancer, and 26 without tumors as controls). In patients with adenoma, high triglyceride and low adiponectin were associated with a significant increase in the odds ratio (OR) by univariate analysis. Only a low adiponectin level was related to increased adenoma risk, with an adjusted OR for low level (<11 μg/mL) to high (≥11 μg/mL) of 5.762 (95% confidence interval (CI):1.683-19.739, P=0.005). In the patients with early cancer, high body mass index, high triglyceride, and low adiponectin were associated with a significant increase in OR in univariate analysis. Imultivariate analysis, only low adiponectin was significantly associated with early cancer, with an adjusted OR of 4.495 (95% CI:1.090-18.528, P=0.038). However, in patients with advanced cancer, low adiponectin was not recognized as a significant risk factor for advanced ***: A decreased level of adiponectin is str

Terahertz One-Chip CMOS Transceiver

Titanium Dioxide Photocatalysis:Present Status and Trends

2019年全国微波毫米波会议

作者： Minoru fujishima hiroshima University

The 300 GHz band, which is one of terahertz frequency bands, has low atmospheric attenuation and can be used for communication over a wide band. Achieving ultrahigh-speed wireless communication using a wide band is a candidate for the sixth-generation technology targeted for 100 Gbps, the next of the fifth generation starting from 2020. In this trend, channel assignment in the 300 GHz band was proposed by IEEE 802.15.3 d in 2017. We have implemented a one-chip transceiver using channels indicated by IEEE 802.15.3 d using a CMOS integrated circuit so that it can be incorporated into common communication terminals. In this talk, we will discuss how to realize a terahertz transceiver using a CMOS integrated circuit and what applications will expand if terahertz communication is realized.

Sodium-doped carbon nitride nanotubes （Nax-CNNTs） were prepared by a green and simple two-step method and applied in photocatalytic water splitting for the first time. Transmission electron microscopy （TEM） element mapping and X-ray photoelectron spectroscopy （XPS） measurements confirm that sodium was successfully introduced in the carbon nitride nanotubes （CNNTs）, and the intrinsic structure of graphitic carbon nitride （g-C3N4） was also maintained in the products. Moreover, the porous structure of the CNNTs leads to relatively large specific surface areas. Photocatalytic tests indicate that the porous tubular structure and Na＋ doping can synergistically enhance the hydrogen evolution rate under visible light （λ 〉 420 nm） irradiation in the presence of sacrificial agents, leading to a hydrogen evolution rate as high as 143 μmol·h-1 （20 mg catalyst）. Moreover, other alkali metal-doped CNNTs, such as Lix-CNNTs and Kx-CNNTs, were tested; both materials were found to enhance the hydrogen evolution rate, but to a lower extent compared with the Nax-CNNTs. This highlights the general applicability of the present method to prepare alkali metal-doped CNNTs; a preliminary mechanism for the photocatalytic hydrogen evolution reaction in the Nax-CNNTs is also proposed.
