Carbon dots induce endoplasmic reticulum stress-mediated lipid dysregulation and embryonic developmental toxicity in zebrafish.

Carbon dots (CDs) are widely utilized due to their exceptional physical and chemical properties. Nevertheless, there is a paucity of research examining the potential toxicity of carbon dots to human health, particularly with regard to developmental toxicity. The present study demonstrated that exposure to CDs resulted in increased mortality and malformations in zebrafish embryos.

Anti-Inflammatory Effects of Two-Week Sacral Nerve Stimulation Therapy in Patients With Ulcerative Colitis.

Background And Aims: Sacral nerve stimulation (SNS) showed anti-inflammatory properties in animal models of inflammatory bowel disease. We aimed to evaluate the effectiveness and safety of SNS in patients with ulcerative colitis (UC).

Materials And Methods: Twenty-six patients with mild and moderate disease were randomized into two groups: SNS (delivered at S3 and S4 sacral foramina) and sham-SNS (delivered 8-10 mm away from sacral foramina), with the therapy applied once daily for one hour, for two weeks.

Stage-Related Neurotoxicity of BPA in the Development of Zebrafish Embryos.

Bisphenol A (BPA) is one of the most widely produced chemicals in the world used in the production of epoxy resins and polycarbonate plastics. BPA is easily migrated from the outer packaging to the contents. Due to the lipophilic property, BPA is easily accumulated in organisms.

Developmental toxicity of bromoacetamide via the thyroid hormone receptors-mediated disruption of thyroid hormone homeostasis in zebrafish embryos.

Bromoacetamide (BAcAm) is a nitrogenous disinfection by-product. We previously found that BAcAm induced developmental toxicity in zebrafish embryos, but the underlying mechanisms remain to be elucidated. Since thyroid hormones (THs) homeostasis is crucial to development, we hypothesized that disruption of THs homeostasis may play a role in the developmental toxicity of BAcAm.
