Due to their markedly distinct protein compositions and structures, goat milk and cow milk display substantially different characteristics. In this study, the quality and composition of goat milk and cow milk were studied after being refrigerated at 4 °C for 7 days, with a particular focus on protein oxidation and aggregation states. The results revealed that alongside increases in acidity, microbial colony count, and hydrolysis, there was a significant change in the protein aggregation state beginning on the second day.

Carbonyl sulfide (COS) is the most abundant and longest-lasting organic reduced sulfur compound in the atmosphere. Removing it is a critical and challenging aspect in desulfurization technology in order to comply with global restrictions on harmful emissions. Catalytic hydrolysis refers to the process whereby COS reacts with water under the influence of a catalyst to generate carbon dioxide and hydrogen sulfide.

Traditional wood-plastic composites (WPC) face numerous challenges in their applications, such as the lack of flexibility, cushioning performance, water barrier properties, biodegradability and recyclability. To address these issues, in this work, a recyclable lignocellulosic biocomposites with excellent comprehensive performance was developed using cork flour and poly(1,4-dioxan-2-one) (PPDO) as the green raw materials. The prepared cork/PPDO WPC contained up to 70 wt% cork flour, conferring them with enhanced flexibility (elongation at break >10 %) and cushioning performance due to the strong interactions between PPDO and cork flour, as well as the cork unique flexibility from cork cavity structure and suberin.

Alzheimer's Disease (AD) constitutes approximately 70 % of dementia cases and is the most prevalent form of dementia. Current therapeutic options, including acetylcholinesterase inhibitors and N-methyl d-aspartate (NMDA) receptor antagonists, provide symptomatic relief but do not cure the disease and often come with side effects. The primary pathological features of AD are amyloid plaques and neurofibrillary tangles, with amyloid plaques formed by the abnormal accumulation of Amyloid-β (Aβ).

Pyruvate dehydrogenase kinase (PDK) 1 is one of four isozymes that inhibit the oxidative decarboxylation of pyruvate to acetyl-CoA via pyruvate dehydrogenase. PDK activity is elevated in fasting or starvation conditions to conserve carbohydrate reserves. PDK has also been shown to increase mitochondrial fatty acid utilization.
