Bisphenol S (BPS) has been put into production as a wide range of Bisphenol A (BPA) alternatives, while little is known regarding its cardiac developmental toxicity. To explore the effect of BPS on cardiomyocyte differentiation and its mechanism, our study established the human embryonic stem cell-cardiomyocyte differentiation model (hESC-CM), which was divided into early period of differentiation (DP1:1-8d), anaphase period of differentiation (DP2:9-16d) and whole stage of differentiation (DP3:1-16d) exposed to human-related levels of BPS. We found that the survival rate of cardiomyocytes was more sensitive to BPS at the early stage of differentiation than at the anaphase stage of differentiation, and exposure to higher than 30 µg/mL BPS throughout the differentiation period decreased the expression of cTnT.

A growing body of evidence indicates that microcystins (MCs) exposure may cause metabolic diseases. However, studies exploring the effects of MCs exposure on the risk of metabolic syndrome (MetS) in humans are currently lacking, and the underlying mechanisms remain unclear. Here, we conducted a cross-sectional study in central China to explore the effect of serum MCs on MetS, and assessed the mediation effects of the inflammation biomarker, white blood cell (WBC) level, in this relationship.

This study aimed to investigate the protective effects of vitamin B complex and alpha-lipoic acid (ALA) pre-treatments on hepatic ischemia-reperfusion injury (IRI) in rats, focusing on their potential to enhance antioxidant defense mechanisms and reduce post-ischemic liver damage. Thirty male Wistar albino rats were divided into four groups: sham group (n = 10), IRI group (n = 10), vitamin B group (n = 10), vitamin B + ALA group (n = 10). In the IRI, vitamin B, and vitamin B + ALA groups, the rats underwent 45 min of hepatic ischemia followed by 60 min of reperfusion.

Purpose: Fentanyl, a highly lipophilic opioid, was developed as a sublingual fentanyl tablet (SFT) for the management of breakthrough cancer pain (BTcP), and its efficacy and safety were confirmed in a randomized, controlled study. We investigated the effectiveness and safety of SFT administered to alleviate BTcP in a real-world setting.
Materials And Methods: In this prospective, open, single-cohort study, conducted in 13 referral hospitals in South Korea, opioid-tolerant cancer patients receiving around-the-clock opioids for persistent cancer pain were enrolled if the individual had BTcP ≥ 1 episode/day during the preceding week.
Purpose: To evaluate the safety and efficacy of sublingual methazolamide in patients with open-angle glaucoma (OAG) and inform future trial design.
Methods: Fourteen participants (28 eyes) aged 50 to 90 years with bilateral OAG and intraocular pressure (IOP) between 18 and 35 mmHg after medication washout were included. Participants were randomized to receive either 25 mg or 50 mg of sublingual methazolamide once daily for one week, followed by twice-daily administration during the second week.
