Multiwalled carbon nanotubes (MWCNTs) were covalently modified with imidazolium salt-based ionic liquids (ILs). Coupling of acid chloride-functionalized MWCNTs with commercially available (3-aminopropyl)imidazole, followed by the reaction with n -butyl bromide, afforded 1-butylimidazolium bromide salt-functionalized MWCNTs ( f -3a ). The bromide anion of f- 3a could be exchanged with BF 4 -, PF 6 -, and NTf 2 - ( N, N -bis((trifluoromethyl)sulfonyl)amide) by metathesis and afforded functionalize

These findings provide further evidence for a pathogenic role of the α-synuclein oligomer and suggest that CSF levels of α-synuclein oligomer can be a reliable marker for PD.

This study examines: 1) how Korean elementary school teachers perceive recent curriculum reforms; 2) where their perceptions emanate from; and 3) what support teachers need in order to implement curriculum reforms actively and effectively. This study has shown that teachers generally harbour negative and unconstructive feelings about curriculum reform. These feelings negatively impact their involvement in and commitment to implementing reform. Several issues to be considered for teacher training

A Gram-negative bacterium, designated strain EMB117T, was isolated from a municipal wastewater treatment plant and characterized by polyphasic taxonomy. The cells were non-spore-forming rods that showed gliding motility. Optimal growth occurred at 25-30 degrees C and pH 7.0-8.0. Strain EMB117T contained phosphatidylethanolamine as the predominant polar lipid, and the major fatty acids were iso-C(15 : 0), iso-C(17 : 0) 3-OH, iso-C(15 : 0) 3-OH and summed feature 3 (C(16 : 1)omega7c and/or iso-C(1

Background: As the metabolic significance of sarcopenic obesity (SO) is revealed, finding an appropriate index to detect SO is important, especially for type 2 diabetes mellitus (T2DM) patients with accompanying metabolic dysfunction. Methods: for women) and strength (handgrip strength <28.0 kg for men, <18.0 kg for women) and/or reduced physical performance (gait speed <1.0 m/sec). Obesity was defined as a WC ≥90 cm in men and ≥85 cm in women. The WHR, WHtR, and WWI were calculated by dividing

This study investigates how characteristics of a collaborative professional learning activity support and hinder teacher learning and growth by examining the experiences of three Korean secondary teachers who participated in a school-initiated collaborative teacher learning project. The findings demonstrated that this learning opportunity supported teachers in their learning and professional development in the following ways. First, teachers experienced professional growth through collaborative

Abstract Although sleep is one of the most conserved behaviors, the intracellular mechanism regulating sleep/wakefulness remains unknown. We recently identified a protein kinase, SIK3, as a sleep-regulating molecule. Mice that lack a well-conserved protein kinase A (PKA) phosphorylation site, S551, showed longer non-rapid eye movement (NREM) sleep and increased NREMS delta density. S551 of SIK3 is conserved in other members of the SIK family, such as SIK1 (S577) and SIK2 (S587). Here, we examine

A Gram-negative, non-motile, rod-shaped bacterium, designated strain EMB47(T), was isolated from activated sludge performing enhanced biological phosphorus removal in a sequencing batch reactor. Growth was observed between 10 and 40 degrees C (optimum, 25-35 degrees C) and between pH 5.0 and 8.5 (optimum, pH 7.5-8.0). The predominant fatty acids of strain EMB47(T) were iso-C(16 : 0) 3-OH, iso-C(15 : 1) G, C(15 : 0), iso-C(15 : 0), iso-C(14 : 0) and iso-C(16 : 0) and it contained phosphatidyletha

BACKGROUND/AIMS: Previous studies have revealed that glucagon-like peptide-1 receptor agonist (GLP-1RA) and thiazolidinedione (TZD) can improve nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH). However, comprehensive research comparing the effects of GLP-1RA and TZD is limited. Thus, this study aimed to compare the effects of GLP-1RA and TZD on NAFLD or NASH through a network meta-analysis. METHODS: The PubMed, Embase, Web of Science, and Scopus databases were sear

Prior research revealed that Polaromonas naphthalenivorans CJ2 carries and expresses genes encoding the gentisate metabolic pathway for naphthalene. These metabolic genes are split into two clusters, comprising nagRAaGHAbAcAdBFCQEDJI'-orf1-tnpA and nagR2-orf2I''KL (C. O. Jeon, M. Park, H. Ro, W. Park, and E. L. Madsen, Appl. Environ. Microbiol. 72:1086-1095, 2006). BLAST homology searches of sequences in GenBank indicated that the orf2 gene from the small cluster likely encoded a salicylate 5-hy
