[Endoscopic retrograde cholangiopancreatography transgastric guided by endoscopic ultrasound in a single endoscopic procedure: first case in the Colombian Caribbean region].

Dagoberto Rafael, Duarte Misol · Marco Antonio, Medina Ortega · Fernando Luis, García Del Risco · Jesús Maria, Pérez Orozco

Endoscopic retrograde cholangiopancreatography (ERCP) is the standard treatment for biliary tract diseases; however, in patients with Roux-en-Y gastric bypass, it is technically challenging due to altered anatomy. We report the case of a 43 year old woman with a history of gastric bypass who presented with abdominal pa...

Regioselective Functionalization of Propane and n-Butane through Nickel-mediated Radical Locking.

Hugo Jiménez-Cristóbal · Akshay M. Nair · Poulami Mukherjee · Adhya Suresh · y 4 más

Gaseous alkanes constitute the most abundant carbon feedstock, yet their direct utilization in synthesis remains challenging due to their gaseous nature and the inertness of their C(sp3)–H bonds. Regioselective functionalization of C3 and C4 alkanes, such as propane and n-butane, poses an additional significant challen...
