The Arabidopsis Receptor Kinase IRK Is Polarized and Represses Specific Cell Divisions in Roots.

Development of multicellular organisms requires coordination of cell division and differentiation across tissues. In plants, directional signaling, and implicitly cell polarity, is proposed to participate in this coordination; however, mechanistic links between intercellular signaling, cell polarity, and cellular organization remain unclear. Here, we investigate the localization and function of INFLORESCENCE AND ROOT APICES RECEPTOR KINASE (IRK) in root development.

Perioperative administration of gabapentin for shoulder arthroscopy: a prospective, randomized, double-blind, placebo-controlled study.

Recent studies suggest gabapentin has opioid-sparing effects and may reduce acute postoperative pain. However, there is limited research on the efficacy of gabapentin when combined in a multimodal approach after shoulder arthroscopy under general anesthesia with an interscalene block. We conducted prospective, double-blind study of 70 patients who were randomized to receive either 300 mg of gabapentin or placebo 1 hour before surgery, then twice a day for 2 days.
