REVIEW
Katherine C Nickels, Elaine C Wirrell
Stiripentol is a structurally unique antiepileptic drug that has several possible mechanisms of action, including diverse effects on the gamma-aminobutyric acid (GABA)-A receptor and novel inhibition of lactate dehydrogenase. Because of its inhibition of several cytochrome P450 enzymes, it has extensive pharmacokinetic interactions, which often necessitates reduction in doses of certain co-therapies, particularly clobazam. Stiripentol also has a neuroprotective action, by reducing calcium-mediated neurotoxicity...

Xiong Li, Hang Li, Gang Yang
Electric fields exist ubiquitously in chemical and biological systems while how to affect the interfacial adsorption processes remain elusive. Here, molecular dynamics simulations are used to understand at a molecular level the adsorption of metal ions at the interface of aqueous solutions and clay materials that are generally endowed with strong electric fields. In absence of electric fields, even Cs(+), one of the strongest adsorbed metal ions, is facile to detach from solvated clay surfaces. Electric fields are critical to construct stable inner-sphere complexes and enhance pronouncedly the adsorption strengths of both inner- and outer-sphere complexes...

BACKGROUND: In hydrocephalus shunt surgery, a peritoneal catheter is traditionally inserted with laparotomy incision. The abdominal incision length will not be shorter than 3 cm in most cases. A longer incision has to be made in obese patients. The lateral position in lumboperitoneal shunt (LPS) surgery also increases the difficulty of laparotomy. The present report introduces a simple technique of pneumoperitoneal puncture for peritoneal catheter placement in LPS. METHODS: Twenty-eight communicating hydrocephalus cases underwent pneumoperitoneal puncture in an LPS operation...

The performance of an ultrafiltration (UF)-biochar process was evaluated in comparison with a UF membrane process for the removal of humic acid (HA). Bench-scale UF experiments were conducted to study the rejection and flux trends under various hydrodynamic, pH, ionic strength, and pressure conditions. The resistance-in-series model was used to evaluate the processes and it showed that unlike stirred conditions, where low fouling resistance was observed (28.7 × 10(12) m(-1) to 32.5 × 10(12) m(-1)), higher values and comparable trends were obtained for UF-biochar and UF alone for unstirred conditions (28...

PURPOSE: Corneal melting with perforation is a severe ophthalmic complication of autoimmune disorders such as rheumatoid arthritis. It requires urgent medical management in order to maintain the integrity of the globe and preserve vision. Treating this complication by penetrating keratoplasty is problematic due to the high rate of recurrence of corneal melting as well as other complications. We describe the use of a tectonic fresh-tissue corneolimbal covering graft. METHODS: An interventional case series including three patients that presented to our tertiary center between 2000 and 2015 with corneal melting and perforation, secondary to rheumatoid arthritis...
