Bee venom(BV),one of the most commonly encountered types of animal venom,consists of a mixture of chemical agents that cause allergic reactions in the human body.⑴BV therapy,in which BV is exploited for medicinal purposes,is available worldwide,mainly used in Asia,Eastern Europe,and South America.(2)BV therapy has been applied to treat a diverse set of diseases including various musculoskeletal conditions such as arthritis and rheumatism,arthralgia,chronic recalcitrant neuralgia,(3-5)Parkinson's disease,(6,7)postherpetic neuralgia,(8)and morphea.(9)Although the therapeutic utility of BV has been demonstrated,extensive studies regarding the safety of BV as a therapeutic agent have identified potential side effects,ranging from minor skin reactions that typically resolve over several days to severe life-threatening immune responses such as anaphylaxis.

Obesity is associated with a number of metabolic abnormalities such as type 2 diabetes and has become a major health problem worldwide. In the present study, we investigated the effects of Epimedium koreanum Nakai(Herba Epimedii, HE) and its main constituent icariin on the adipocyte differentiation in 3T3-L1 preadipocytes. HE extract and icariin significantly reduced lipid accumulation and suppressed the expressions of PPARγ, C/EBPα, and SREBP-1c in 3T3-L1 adipocytes. They also inhibited fatty acid synthase(FAS), acyl-Co A synthase(ACS1), and perilipin. Moreover, HE extract and icariin markedly increased the phosphorylation of AMPK. These results indicated that HE extract and icariin can inhibit the adipocyte differentiation through downregulation of the adipogenic transcription factors, suggesting that HE containing icariin may be used as a potential therapeutic agent in the treatment and prevention of obesity.

Atomic layer deposition ofan Al2O3 dielectric on ultrathin graphite is studied in order to investigate the integration of a high k dielectric with graphite-based substrates. Electron beam irradiation on the graphite surface is followed by a standard atomic layer deposition ofAl2O3. Improvement of the Al2O3 layer deposition morphology was observed when using this radiation exposure on graphite. This result may be attributed to the amorphous change of the graphite layers during electron beam irradiation.

In this study, we prepared horn-like ZnO structures on carbon films（ZnO/CF） by electrodeposition and decorated the ZnO horns with different metals（Ag, Au, and Pt） via photodeposition（M-ZnO/CF）. Using M-ZnO/CF as photocatalysts, we examined ways to enhance solar hydrogen production from various points of view, such as modifying the intrinsic physical properties and thermodynamics of the materials, and varying the chemical environment during M-ZnO/CF fabrication. In particular, we focused on the effects of the carbon film and metals in M-ZnO/CF hybrid photocatalysts on solar hydrogen production. The type of metal nanoparticles is an important factor in solar hydrogen production because the deposition rate and electrical conductivity of each metal affect the proton-water reduction ability.
