Silica thin films synthesized sol–gel process are proposed as flexible encapsulation materials.A sol–gel process provides a dense and stable amorphous silica structure,yielding an extremely high elastic deformation limit of 4.9%and extremely low water vapor transmission rate(WVTR)of 2.90×10^(−4)g/(m^(2)∙day)at 60℃and relative humidity of 85%.The WVTR is not degraded by cyclic bending deformations for the bending radius corresponding to a tensile strain of 3.3%in the silica encapsulation film,implying that the silica thin film is robust against the formation of pinhole-type defects by cyclic bending *** organic solar cells encapsulated with the silica films operate without degradation in power conversion efficiency for 50,000 bending cycles for a bending radius of 6 mm.

The technique of region of interest-based positron emission tomography is limited by its poor reli-ability and relatively few examined brain regions. In the present study, we compared brain metabo-lism assessed using fluorine-18-fluorodeoxyglucose positron emission tomography between 14 at-tention-deficit hyperactivity disorder （ADHD） patients and 15 normal controls with scoliosis at resting state by statistical parametric mapping. Glucose metabolism was decreased in the left parahippo-campal gyrus, left hippocampus, left anterior cingulate gyrus, right anterior and posterior lobes of the cerebellum, left superior temporal gyrus, left insula, left medial and middle frontal gyri, right medial frontal gyrus, and left basal ganglia （putamen, amygdala, and caudate nucleus） in children with ADHD. These data suggest that children with ADHD exhibit hypometabolism in various brain regions compared to controls, indicating that ADHD symptoms are unlikely the result of abnormalities in specific areas.

Background Ursodeoxycholic acid(UDCA),statins,and ezetimibe(EZE)have demonstrated beneficial effects against nonalcoholic fatty liver disease(NAFLD).We investigated the efficacy of the combination of UDCA and the mix of rosuvastatin(RSV)/EZE in the treatment of *** NAFLD mouse models were developed by injecting thioacetamide,fasting,and high-carbohydrate refeeding,highfat diet,and choline-deficient L-amino acid-defined high-fat diet(CDAHFD).Low-dose UDCA(L-UDCA;15 mg/kg)or highdose UDCA(H-UDCA;30 mg/kg)was administered with RSV/*** also employed an in vitro model of NAFLD developed using palmitic acid-treated Hepa1c1c7 *** Co-administration of RSV/EZE with UDCA significantly decreased the collagen accumulation,serum alanine aminotransferase(ALT)levels,and mRNA levels of fibrosis-related markers than those observed in the vehicle group in thioacetamide-treated mice(all P<0.01).In addition,in the group fasted and refed with a high-carbohydrate diet,UDCA/RSV/EZE treatment decreased the number of apoptotic cells and serum ALT levels compared with those observed in the vehicle group(all P<0.05).Subsequently,H-UDCA/RSV/EZE treatment decreased the number of ballooned hepatocytes and stearoyl-CoA desaturase 1(SCD-1)mRNA levels(P=0.027)in the liver of high-fat diet-fed mice compared with those observed in the vehicle *** the CDAHFD-fed mouse model,UDCA/RSV/EZE significantly attenuated collagen accumulation and fibrosis-related markers compared to those observed in the vehicle group(all P<0.05).In addition,UDCA/RSV/EZE treatment significantly restored cell survival and decreased the protein levels of apoptosis-related markers compared to RSV/EZE treatment in palmitic acid-treated Hepa1c1c7 cells(all P<0.05).Conclusion Combination therapy involving UDCA and RSV/EZE may be a novel strategy for potent inhibition of NAFLD progression.
