Development of a Family Support Scale for Diet Therapy for Male Workers with type 2 diabetes.

Aim: Dietary self-care for patients with type 2 diabetes can be improved with family support. The purpose of this study was to develop a scale to assess family support for diet therapy for male workers with type 2 diabetes and to examine its reliability and validity.

Methods: In this cross-sectional study, we collected data from 110 Japanese male workers with type 2 diabetes.

Degradation pathway of plant complex-type -glycans: identification and characterization of a key α1,3-fucosidase from glycoside hydrolase family 29.

Plant complex-type -glycans are characterized by the presence of α1,3-linked fucose towards the proximal -acetylglucosamine residue and β1,2-linked xylose towards the β-mannose residue. These glycans are ultimately degraded by the activity of several glycoside hydrolases. However, the degradation pathway of plant complex-type -glycans has not been entirely elucidated because the gene encoding α1,3-fucosidase, a glycoside hydrolase acting on plant complex-type -glycans, has not yet been identified, and its substrate specificity remains to be determined.

Rapid nuclear import of short nucleic acids.

Exogenous short-chain nucleic acids undergo rapid import into the nucleus. Fluorescence-labeled dT1-13 DNA microinjected into the cytoplasm domain of a HeLa cell was rapidly imported into the nucleus domain within 1min. This is much more rapid than what has been observed for intracellular diffusion of small molecules.

Synthesis of nitrogen heterocycles via α-aminoalkyl radicals generated from α-silyl secondary amines under visible light irradiation.

We have succeeded in the visible light-mediated synthetic use of α-aminoalkyl radicals derived from α-silyl secondary amines toward addition to α,β-unsaturated carbonyl compounds. The resulting γ-aminocarbonyl compounds are converted into γ-lactams and pyrroles in a one-pot process.

alpha-Mannosidase-catalyzed synthesis of a (1-->2)-alpha-D-rhamnodisaccharide derivative.

Enzymatic transglycosylation using p-nitrophenyl alpha-D-rhamnopyranoside as the glycosyl donor and 6equiv of ethyl 1-thio-alpha-D-rhamnopyranoside as the glycosyl acceptor yielded a D-rhamnooligosaccharide derivative. The reaction was catalyzed by jack bean alpha-mannosidase in a 1:1 (v/v) mixture of 0.1 M sodium citrate buffer (pH4.
