Adzuki bean () extract reduces amyloid-β aggregation and delays cognitive impairment in models of Alzheimer's disease.

Background/objectives: Alzheimer's disease is a neurodegenerative disease that induces symptoms such as a decrease in motor function and cognitive impairment. Increases in the aggregation and deposition of amyloid beta protein (Aβ) in the brain may be closely correlated with the development of Alzheimer's disease. In this study, the effects of an adzuki bean extract on the aggregation of Aβ were examined; moreover, the anti-Alzheimer's activity of the adzuki extract was examined.

Identification and Synthesis of (Z,Z)-8,11-Heptadecadienyl Formate and (Z)-8-Heptadecenyl Formate: Unsaturated Aliphatic Formates Found in the Unidentified Astigmatid Mite, Sancassania sp. Sasagawa (Acari: Acaridae).

We identified two aliphatic formates, (Z,Z)-8,11-heptadecadienyl formate and (Z)-8-heptadecenyl formate in the opisthonotal gland secretions of an unidentified acarid species, namely Sancassania sp. Sasagawa. Both compounds were isolated using silica gel column chromatography and the structures were elucidated by ¹H-NMR and GC/FT-IR.

Subcellular Localization and Polymorphism of Bovine FABP4 in Bovine Intramuscular Adipocytes.

Fatty acid binding protein 4 (FABP4) I74 V, a gene polymorphism associated with unsaturated fatty acid contents, was discovered in Japanese Black cattle. Individuals with FABP4 I/I genotype contain a significantly high level of palmitoleic acid compared to those with FABP4 V/V genotype. It remains unknown how the FABP4 polymorphism leads to different palmitoleic acid contents.

ALS-associated P56S-VAPB mutation restrains 3T3-L1 preadipocyte differentiation.

Amyotrophic lateral sclerosis (ALS), which is the most common motor neuron disease in adults, is a neurodegenerative disease that involves the selective and systematic death of upper and lower motor neurons. In addition to the motor neuron death, altered metabolic functions, such as dyslipidemia, have also been reported for ALS patients; however, the underlying mechanism remains unknown. In the present study, we investigated the effects of ALS-associated P56S-vesicle-associated membrane proteinassociated protein B (VAPB), P56S-VAPB on 3T3-L1 preadipocyte differentiation and on the expression of differentiation-associated genes and unfolded protein response (UPR)-related genes.
