Comparative analysis of Student's live online learning readiness during the coronavirus (COVID-19) pandemic in the higher education sector.

Amid the coronavirus outbreak, many countries are facing a dramatic situation in terms of the global economy and human social activities, including education. The shutdown of schools is affecting many students around the world, with face-to-face classes suspended. Many countries facing the disastrous situation imposed class suspension at an early stage of the coronavirus outbreak, and Asia was one of the earliest regions to implement live online learning.

Injectable microparticle-gel system for prolonged and localized lidocaine release. II. In vivo anesthetic effects.

Current treatment protocols for postoperative pain are beset by either the short duration of the anesthetic effect or requirement of hospitalization of the patients. We reported herein a novel treatment by applying to the surgical site a biodegradable microparticle-gel system for prolonged and localized release of encapsulated anesthetic drugs. In a previous publication, lidocaine-loaded poly(D,L-lactic acid) microspheres were fabricated and their formulations were optimized.

Injectable microparticle-gel system for prolonged and localized lidocaine release. I. In vitro characterization.

Current treatment protocol for postoperative pain is to infuse anesthetic solution around nerves or into the epidural space. This clinical practice is beset by the short duration of the anesthetic effect unless the infusion is continuous. Continuous infusion, however, requires hospitalization of the patients, thereby increasing medical costs.
