Tannic Acid Modulates Voltage-gated K+ Channels to Promote Neuritogenesis in Neuronal N2A Cells.

In a previous report, we showed that voltage-gated K+ (Kv) Kv1 and Kv2 channels are involved in cAMP-induced neuritogenesis of mouse neuronal N2A cells. In this report, we examined the effects of tannic acid (TA) on Kv channels and neuritogenesis in N2A cells. TA (15 μM) mildly enhanced Kv currents at -30 to -20 mV but strongly inhibited Kv currents at higher voltages, causing a preferential activation of currents at low voltages.

Electroacupuncture of ST36 and PC6 for postoperative gastrointestinal recovery: A systematic review and meta-analysis.

Objective: This study was designed to determine the efficacy and safety of electroacupuncture (EA) at acupoints ST36 and/or PC6 for postoperative gastrointestinal (GI) recovery.

Method: Studies were retrieved from the PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang, and Airiti library databases from inception to January 23, 2024. Randomized controlled trials (RCTs) that evaluated the effect of EA at ST36 and/or PC6 on postoperative GI recovery were reviewed.

Neural plate pre-patterning enables specification of intermediate neural progenitors in the spinal cord.

Dorsal-ventral patterning of neural progenitors in the posterior neural tube, which gives rise to the spinal cord, has served as a model system to understand how extracellular signals organize developing tissues. While previous work has shown that signaling gradients diversify progenitor fates at the dorsal and ventral ends of the tissue, the basis of fate specification in intermediate regions has remained unclear. Here we use zebrafish to investigate the neural plate, which precedes neural tube formation, and show that its pre-patterning by a distinct signaling environment enables intermediate fate specification.

Minimally invasive prone lateral retropleural or retroperitoneal antepsoas approach spinal surgery using the rotatable radiolucent Jackson table.

Background: Prone lateral spinal surgery for simultaneous lateral and posterior approaches has recently been proposed to facilitate surgical room efficiency. The purpose of this study is to evaluate the feasibility and outcomes of minimally invasive prone lateral spinal surgery using a rotatable radiolucent Jackson table.

Methods: From July 2021 to June 2023, a consecutive series of patients who received minimally invasive prone lateral spinal surgery for various etiologies by the same surgical team were reviewed.

Passively Q-switched 976-nm monolithic ytterbium fiber laser with 4-W power.

We developed a 915-nm pumped, passively Q-switched 976-nm ytterbium all-fiber laser with an average output power of 4.3 W. The laser utilizes a 16-cm Yb gain fiber, passively Q-switched by a 1.
