The aim of this study was to investigate susceptibility to the neurotoxicity of local anesthetic agents in a model of gestational diabetes mellitus (GDM). SH-SY5Y cells were cultured at different concentrations of glucose and subsequently treated with 1 mmol/l bupivacaine for 6 h. Reactive oxygen species (ROS) production and apoptosis were assessed using flow cytometry in each group of cells. The MTT method was utilized to detect cell survival, and western blot analysis was used to examine changes in 78 kDa glucose‑regulated protein (GRP78) levels in neuronal cells. In all groups, levels of ROS production, cell survival and GRP78 expression were significantly different (P<0.01) following the addition of various concentrations of glucose and bupivacaine, as well as for the interaction between different concentrations of the anesthetic agents, demonstrating a statistically significant difference. In conclusion, the susceptibility of SH-SY5Y cells to the neurotoxicity of local anesthetic agents was enhanced in a model of GDM.

Expansion of atypical memory B cells (aMBCs) was demonstrated in malaria-exposed individuals. To date, the generation of P. vivax-specific aMBCs and their function in protective humoral immune responses is unknown.

Purpose: Regulating intraocular pressure (IOP), mainly via the trabecular meshwork (TM), is critical in developing glaucoma. Whereas current treatments aim to lower IOP, directly targeting the dysfunctional TM tissue for therapeutic intervention has proven challenging. In our study, we utilized Dexamethasone (Dex)-treated TM cells as a model to investigate how extracellular vesicles (EVs) from immortalized corneal stromal stem cells (imCSSCs) could influence ANGPTL7 and MYOC genes expression within TM cells.

Purpose: To investigate the effect of Rho-associated protein kinase (ROCK) inhibitor Y27632 on bioenergetic capacity and resilience of corneal endothelial cells (CECs) under metabolic stress.
Methods: Bovine CECs (BCECs) were treated with Y27632 and subjected to bioenergetic profiling using the Seahorse XFp Analyzer. The effects on adenosine triphosphate (ATP) production through oxidative phosphorylation and glycolysis were measured.

Purpose: Although mechanical injury to the cornea (e.g. chronic eye rubbing) is a known risk factor for keratoconus progression, how it contributes to loss of corneal integrity is not known.

Lysophosphatidic acid (LPA) exerts its physiological roles through the endothelialdifferentiation gene (EDG) family LPA receptors (LPAR1-3) or the non-EDG family LPA receptors (LPAR4-6). LPAR6 plays crucial roles in hair loss and cancer progression, yet its structural information is very limited. Here, we report the cryoelectron microscopy structure of LPA-bound human LPAR6 in complex with a mini G or G protein.
