Schlemm's Bidirectional Fluid Wave and Luminal Blood Reflux as Novel Intra-Operative Signs Confirming Optimal Placement of the iStent.

Purpose: Trabecular micro-bypass devices (TBDs) such as the iStent series (Glaukos Corporation, Laguna Hills, CA), are effective in reducing intraocular pressure (IOP). However, precise placement of TBDs is crucial in achieving surgical efficacy, as device malpositioning may lead to suboptimal IOP reduction. We demonstrate two novel intra-operative signs to aid confirmation of accurate iStent placement, without reliance on imaging technologies.

Is minimally invasive glaucoma surgery killing trabeculectomies?

Purpose Of Review: The introduction of minimally invasive glaucoma surgery (MIGS) has changed the surgical landscape of glaucoma surgery. For more than four decades, the most commonly performed glaucoma surgery around the world has been the trabeculectomy. This article examines whether trabeculectomy is still the predominant procedure in glaucoma today, in the context of rapidly emerging MIGS devices and procedures.

EZH2 functional dichotomy in reactive oxygen species-stratified glioblastoma.

Background: EZH2, well-known for its canonical methyltransferase activity in transcriptional repression in many cancers including glioblastoma (GBM), has an understudied non-canonical function critical for sustained tumor growth. Recent GBM consortial efforts reveal complex molecular heterogeneity for which therapeutic vulnerabilities correlated with subtype stratification remain relatively unexplored. Current enzymatic EZH2 inhibitors (EZH2inh) targeting its canonical SET domain show limited efficacy and lack durable response, suggesting that underlying differences in the non-canonical pathway may yield new knowledge.

Recording of single-unit activities with flexible micro-electrocorticographic array in rats for decoding of whole-body navigation.

Micro-electrocorticographic (ECoG) arrays are able to record neural activities from the cortical surface, without the need to penetrate the brain parenchyma. Owing in part to small electrode sizes, previous studies have demonstrated that single-unit spikes could be detected from the cortical surface, and likely from Layer I neurons of the neocortex. Here we tested the ability to useECoG arrays to decode, in rats, body position during open field navigation, through isolated single-unit activities.
