The factors that trigger the pathophysiology of Parkinson's disease (PD) are unknown. However, it is suggested that environmental factors, such as exposure to pesticides, play an important role, in addition to genetic predisposition and aging. Early signs of PD can appear in the gastrointestinal (GI) tract and in the olfactory system, preceding the onset of motor impairments by many years. The present study assessed the effects of oral rotenone administration (30 mg/kg) in inducing GI and olfactory dysfunctions associated with PD in mice...

Thickness effects on thermal conductivities of black phosphorus nanosheets, which are anisotropic in the zigzag and armchair planar directions, are experimentally and theoretically investigated in the thickness range of 13 to 48 nm. The thermal conductivities decrease with the thickness, decreasing from 13 to 8 W m-1 K-1 in the zigzag direction and from 10 to 6 W m-1 K-1 in the armchair direction at 300 K, respectively. The anisotropic thermal conductivities, regardless of the thickness, might result from the anisotropic phonon velocity arising from the hinge-like structure...

Inclusion of carbon nanoparticles in growth medium accelerates timing to flower by down-regulating phytochrome B in a CONSTANS-independent but photoperiod-dependent manner in Arabidopsis thaliana. Despite the recognized importance of nanoparticles in plant development over the last decade, the effect of carbon nanoparticles (CNPs) on plant processes such as photomorphogenesis and flowering time control is poorly understood. We explored the uptake, accumulation and effect of CNPs on seedling development and flowering time control in Arabidopsis thaliana (At)...

Background: The male predominance in the prevalence of autism spectrum disorder (ASD) has motivated research on sex differentiation in ASD. Multiple sources of evidence have suggested a neurophenotypic convergence of ASD-related characteristics and typical sex differences. Two existing, albeit competing, models provide predictions on such neurophenotypic convergence. These two models are testable with neuroimaging. Specifically, the Extreme Male Brain (EMB) model predicts that ASD is associated with enhanced brain maleness in both males and females with ASD (i...

In the present study, we successfully synthesized a porous three-dimensional Prussian blue-cellulose aerogel (PB-CA) composite and used it as a decorporation agent for the selective removal of ingested cesium ions (Cs+ ) from the gastrointestinal (GI) tract. The safety of the PB-CA composite was evaluated through an in vitro cytotoxicity study using macrophage-like THP-1 cells and Caco-2 intestinal epithelial cells. The results revealed that the PB-CA composite was not cytotoxic. An adsorption study to examine the efficiency of the decorporation agent was conducted using a simulated intestinal fluid (SIF)...

A bacterial strain, designated IMCC25901T , was isolated from a freshwater lake, Soyang, in the Republic of Korea. The strain was Gram-stain-negative, aerobic, non-motile, orange-coloured and short rod-shaped. The 16S rRNA gene sequence analysis showed that strain IMCC25901T was most closely related to Flavobacterium yonginense HMD1001T (97.0 %) and formed a robust phylogenetic clade with other species of the genus Flavobacterium. Growth of strain IMCC25901T was observed at 10-30 °C (optimum, 20 °C), pH 6-8 (optimum, pH 7) and 0-1...

The application of laparoscopy for liver surgery is rapidly increasing and the past few years have demonstrated a shift in paradigm with a trend towards more extended and complex resections. The development of instruments and technical refinements with the effective use of magnified caudal laparoscopic views have contributed to the ability to overcome the limitation of laparoscopic liver resection. The Endoscopic and Laparoscopic Surgeons of Asia (ELSA) Visionary Summit 2017 and the 3rd Expert Forum of Asia-Pacific Laparoscopic Hepatectomy organized hepatobiliary pancreatic sessions in order to exchange surgical tips and tricks and discuss the current status and future perspectives of laparoscopic hepatectomy...

Membrane proteins are of great research interest, particularly because they are rich in targets for therapeutic application. The suitability of various membrane proteins as targets for therapeutic formulations, such as drugs or antibodies, has been studied in preclinical and clinical studies. For therapeutic application, however, a protein must be expressed and purified in as close to its native conformation as possible. This has proven difficult for membrane proteins, as their native conformation requires the association with an appropriate cellular membrane...

In this study, we addressed how silibinin enhances tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis in various cancer cells. Combined treatment with silibinin and TRAIL (silibinin/TRAIL) induced apoptosis accompanied by the activation of caspase-3, caspase-8, caspase-9, and Bax, and cytosolic accumulation of cytochrome c. Anti-apoptotic proteins such as Bcl-2, IAP-1, and IAP-2 were inhibited as well. Silibinin also triggered TRAIL-induced apoptosis in A549 cells through upregulation of death receptor 5 (DR5)...

AIMS: We have previously identified a chemical scaffold possessing 2-ethoxypropanoic acid (designated as KS15) that directly binds to the C-terminal region of cryptochromes (CRYs: CRY1 and CRY2) and enhances E-box-mediated transcription. However, it is still unclear how KS15 impairs the feedback actions of the CRYs and which chemical moieties are functionally important for its actions. MAIN METHODS: The E-box-mediated transcriptional activities were mainly used to examine the effects of KS15 and its derivatives...
