Published: December 2011

Tubal obstruction is a recognized complication of glaucoma drainage implants. In correcting a blocked tube, the surgeon may be uncertain about shunt competence even after removing the suspected cause of obstruction. We report the use of trypan blue dye to show tubal patency directly after the repair of a blocked Baerveldt tube.

Citronellol (CT) is a naturally occurring lipophilic monoterpenoid which has shown anticancer effects in numerous cancerous cell lines. This study was, therefore, designed to examine CT's potential as an anticancer agent against glioblastoma (GBM). Network pharmacology analysis was employed to identify potential anticancer targets of CT.

Purpose: To describe a technique involving combined endothelialectomy and trypan blue staining to allow for improved visualization and Descemet membrane (DM) removal during endothelial keratoplasty.

Methods: Endothelialectomy with 2 disposable endothelial irrigating cannulas (Vortex and Sterimedix) and an irrigation-aspiration handpiece are described. Several passes over the desired area are made to ensure adequate endothelialectomy treatment.

Electronic address:

Moderate UV-B promotes plant growth, but excessive UV-B inhibits plant development. The induction mechanism of how CtWD40-6 responds to UV-B is still unclear in safflower. Our results showed that CtWD40-6 is expressed at the top of safflower leaves and is strongly induced by UV-B.

Article Synopsis
  • The study investigates the toxicity of salt on obesity using Drosophila larvae and adult flies, testing varying salt concentrations (50-800 µM).
  • At lower concentrations (50 and 200 µM), significant weight gain and increased feeding behavior were observed, with larvae and adult flies displaying abnormal responses to temperature and light stimuli.
  • The findings reveal that while lower salt concentrations induce stronger adverse effects, higher concentrations deter feeding, suggesting a complex relationship between salt intake and obesity-related behaviors.
