Enhancement of elastin expression by transdermal administration of sialidase isozyme Neu2.

Reduction of elastin in the skin causes various skin diseases as well as wrinkles and sagging with aging. Sialidase is a hydrolase that cleaves a sialic acid residue from sialoglycoconjugate. Cleavage of sialic acid from microfibrils by the sialidase isozyme Neu1 facilitates elastic fiber assembly.

The sialidase inhibitor 2,3-dehydro-2-deoxy-N-acetylneuraminic acid is a glucose-dependent potentiator of insulin secretion.

Sialidase cleaves sialic acid residues from a sialoglycoconjugate: oligosaccharides, glycolipids and glycoproteins that contain sialic acid. Histochemical imaging of the mouse pancreas using a benzothiazolylphenol-based sialic acid derivative (BTP3-Neu5Ac), a highly sensitive histochemical imaging probe used to assess sialidase activity, showed that pancreatic islets have intense sialidase activity. The sialidase inhibitor 2,3-dehydro-2-deoxy-N-acetylneuraminic acid (DANA) remarkably enhances glutamate release from hippocampal neurons.

Mitigation of Memory Impairment in Ovariectomized Rats Using Garlic Powder Treated with Subcritical Water.

Women with estrogen deficiency are at the risk of suffering from neurological symptoms such as memory impairment. In the present study, we investigated the effect of garlic, Allium sativum L. (Asparagales: Amaryllidaceae), treated with subcritical water on memory impairment in ovariectomized (OVX) rats.
