This research sought to examine how the physicochemical characteristics of soy globulins and different processing techniques influence the gel properties of soy yogurt. The goal was to improve these gel properties and rectify any texture issues in soy yogurt, ultimately aiming to produce premium-quality plant-based soy yogurt. In this research study, the investigation focused on examining the impact of 7S/11S, homogenization pressure, and glycation modified with glucose on the gel properties of soy yogurt.

Aim: To identify the association of the vitreoretinal surgeons' experience with the time interval between pars-plana vitrectomy (PPV) and cataract extraction (CE).

Methods: Eyes with prior PPV and following CE were included in this retrospective cohort study. The years of practice and the annual case volume were used to describe the surgeons' experience.

Aspidosperma alkaloids, a subclass of monoterpenoid indole alkaloids rich in the Apocynaceae plants, possess remarkable antitumor activities, but the underlying mechanisms have rarely been reported. In the current project, 11-methoxytabersonine (11-MT), an aspidosperma-type alkaloid isolated from Tabernaemontana bovina, significantly inhibited the viability of two human lung cancer cell lines A549 and H157, and the molecular mechanisms were thus investigated. The results showed that 11-MT killed lung cancer cells via induction of necroptosis in an apoptosis-independent manner.

Our recent investigation showed that hepcidin can reduce iron in the brain of iron-overloaded rat by down-regulating iron-transport proteins. It has also been demonstrated that iron is a major generator of reactive oxygen species. We therefore hypothesized that hepcidin could prevent iron accumulation and thus reduce iron-mediated oxidative stress in iron-overloaded rats.

In the light of recent studies, we hypothesized that aspirin might have the functions to regulate the expression of iron transport proteins and then affect cellular iron levels. To test this hypothesis, we investigated the effects of aspirin on expression of iron uptake protein transferrin receptor 1 (TfR1), iron release protein ferroportin 1 (Fpn1) and iron storage protein ferritin using Western blot analysis and on tumor necrosis factor (TNF)-αlpha, interleukin (IL)-6, interleukin (IL)-10 and hepcidin using quantitative real-time PCR in BV-2 microglial cells treated with lipopolysaccharides (LPS). We found that aspirin significantly down-regulated TfR1, while also up-regulated Fpn1 and ferritin expressions in BV-2 microglial cells in vitro.
