A lipophilic piceid lipoate (PIL) was synthesized by enzymatic method to enhance the antioxidant activity of piceid and improve its state in oil system. The highest substrate conversion of 93.71 % was obtained in γ-valerolactone using Novozym 435 as a catalyst, with a piceid/lipoic acid ratio of 1:15 (mM/mM), an enzyme dosage of 40 mg/mL, and 4 Å molecular sieves at 400 mg/mL.

Supramolecular glass and plastic are a new generation of artificial transparent materials that exhibit excellent optical behavior and processability. However, owing to inherent deficiencies in their mechanical toughness and long-term stability, supramolecular materials lack the potential for functionalization and application. Inspired by the toughening phenomena in biological systems, a synergistic covalent-and-supramolecular polymerization strategy was applied to construct plastic-like supramolecular materials with high transmittance the solvent-free one-pot amidation of thioctic acid and (poly)amines.

Purpose: Chronic jet lag (CJL) is known to disrupt circadian rhythms, which regulate various physiological processes, including ocular surface homeostasis. However, the specific effects of CJL on lacrimal gland function and the underlying cellular mechanisms remain poorly understood.
Methods: A CJL model was established using C57BL/6J mice.

Primary biliary cholangitis (PBC) is a chronic disease, the prevalence of which has been increasing in recent years. And the prevalence of patients who test negative with existing diagnostic techniques remains high. It was found that the antigenic BCOADC-E2 protein could detect patients with a negative original test.

Diabetic sensorimotor neuropathy (DSPN) is strongly associated with the extent of cellular oxidative stress and endothelial dysfunction in type 2 diabetes (T2DM). Alpha-lipoic acid (ALA) attenuates the progression of DSPN through its antioxidant and vasculoprotective effects. Kallistatin has antioxidant and anti-inflammatory properties.
