Previous pharmacokinetics and electrophysiological results indicated an important role of nicotine in the modulation of dopamine transporter (DAT). To elucidate the expression changes of DAT on chronic nicotine and smoke administration, the effects of nicotine and passive cigarette smoke on DAT mRNA expression in the ventral tegmental area (VTA) and the substantia nigra (SN) area were examined using in situ hybridization and RNase protection assay. The results showed that chronic nicotine and smoke ...

Control of cell–matrix interactions is a central principle for the design of biomaterial in tissue engineering. In this study, we evaluated a synthetic glycopolymer, which is recognized by the asialoglycoprotein receptor (ASGPR) expressed on the surface of hepatocytes, as an artificial matrix to regulate integrin‐mediated signaling. The phosphorylation of focal adhesion kinase was restricted in hepatocytes cultured on the glycopolymer compared with fibronectin. In addition, there was no reorganization ...

Partially crystalline structure of doped polypyrrole and polyaniline is investigated by the X-ray diffraction experiment and compared with the results from transport measurements. The increase of crystallinity along the direction of polymer chain in pyrrole-hexafluorophosphate (PPy-PF6) film indicates that intrachain disorder plays a critical role in transport in the metallic regime of the metal-insulator (M-I) transition. The X-ray structure of doped polyaniline sample in the insulating regime close ...

Two of the most prevalent problems children facing worldwide are injuries and obesity. We conducted a systematic review of published studies that evaluated the effects of obesity on children with traumatic injuries. Six studies published between 2006 and 2014 were identified, comprising a total of 4594 children: 867 were obese and 3727 were not. Obese children were 25% more likely to have extremity fractures than nonobese children (p = 0.003), and their mortality rate was significantly higher at 4. ...

The amnestic form of mild cognitive impairment (aMCI) is likely a precursor of Alzheimer disease (AD). Both verbal and visual memory tests are used in the diagnosis of aMCI; however, it is unknown which type of test is superior at predicting the underlying pathologic changes associated with AD. In this study, we compared the topography of cortical thinning among 3 subtypes of patients with aMCI: 33 patients with predominant verbal memory impairment (verbal-aMCI), 35 with predominant visual memory impairment ( ...

Heat generation of uranium dioxide (UO 2 ) powder and its pressureless rapid sintering behaviors have been studied using a high‐frequency induction heating apparatus. The porous graphite housing has been used to prevent heat loss and to preheat the uranium oxides, simultaneously. At an elevated temperature, UO 2 powder generated extra heat by itself. The synergism of individual heat generation between the graphite and UO 2 powder could effectively heat the UO 2 to the sintering temperature of 1700° ...

Abstract Triboelectric nanogenerators (TENGs) are considered as one of the most important renewable power sources for mobile electronic devices and various sensors in the Internet of Things era. However, their performance should inherently be degraded by the wearing of contact surfaces after long‐term use. Here, a ferroelectric polymer is shown to enable TENGs to generate considerable electricity without contact. Ferroelectric‐polymer‐embedded TENG (FE‐TENG) consists of indium tin oxide (ITO) electrodes, ...

Two-dimensional transition-metal dichalcogenide (2D TMD) layers are highly attractive for emerging stretchable and foldable electronics owing to their extremely small thickness coupled with extraordinary electrical and optical properties. Although intrinsically large strain limits are projected in them (i.e., several times greater than silicon), integrating 2D TMDs in their pristine forms does not realize superior mechanical tolerance greatly demanded in high-end stretchable and foldable devices of ...

Yak-Kong (YK), a small black soybean (Glycine max) in Korea, contained higher concentrations of antioxidants than ordinary black soybean or yellow soybean in our previous study. We prepared the fermented YK extract by using a novel lactic acid bacterium, Pediococcus pentosaceus AOA2017 (AOA2017) isolated from Eleusine coracana, and found that the antioxidant ability was enhanced after fermentation. In order to investigate the cause of the enhanced antioxidant ability in the fermented YK extract, we ...

In this study, a fine fully lamellar structure was formed with only a stepped-cyclic heat treatment process without hot working. The cast structure before the heat treatment contained large segregation areas and a coarse columnar structure (>1000 μm). Thus, the mechanical properties at room temperature were not ideal. In contrast, the segregation in the microstructures after the heat treatment was mostly removed with the formation of the fine fully lamellar structure (>65 μm). The mechanical properties ...
