Synthetically Relevant Post-Transition State Bifurcation Leading to Diradical and Zwitterionic Intermediates: Controlling Nonstatistical Kinetic Selectivity through Solvent Effects.

A post-transition state surface intersection (PTSSI) between radical and zwitterionic states that causes a bifurcation in the reaction pathway was discovered through density functional theory calculations on potential energy surfaces and ab initio molecular dynamics simulations of cycloadditions between a bicyclobutane and a triazolinedione (BCB-TAD). It was predicted that changes to the solvent polarity would enable control over the dynamic selectivity in this system; indeed, experimental evidence supported this prediction. This work not only provides new insights into an unusual type of post-transition state bifurcation, but also demonstrates how the nonstatistical dynamic effects that control selectivity for such reactions can be manipulated rationally to increase the yields of synthetically useful reactions.

We propose a novel contactless droplet manipulation strategy that combines electrostatic tweezers (ESTs) with lubricated slippery surfaces. Electrostatic induction causes the droplet to experience an electrostatic force, allowing it to move with the horizontal shift of the EST. Because both the EST and the slippery operating platform prepared by a femtosecond laser exhibit a strong binding effect on droplets, the EST droplet manipulation features significant flexibility, high precision, and can work under various operating conditions.

An unusual case of small bowel obstruction (SBO) due to haemostatic gelatin sponge placed during caesarean delivery is presented. A primigravida in their 30s underwent caesarean delivery at 39 weeks, and developed symptoms of SBO from the second postoperative day. Given the worsening condition of the patient and increasing abdominal girth, CT of the abdomen and pelvis was done which revealed features of SBO.

Postoperative pancreatitis is an unusual complication of upper abdominal surgery that can result in severe morbidity and has been associated with postoperative death. It can be caused by trauma to the surface of the gland, injury to pancreatic ducts, vascular compromise, ductal obstruction within the pancreas parenchyma or because of duodenal stagnation. Our database of peritoneal surface malignancy patients was surveyed in a search for patients who manifested signs and symptoms of severe postoperative pancreatitis.
