PERCUTANEOUS TRANSHEPATIC OR ENDOSCOPIC ULTRASOUND-GUIDED BILIARY DRAINAGE IN MALIGNANT DISTAL BILE DUCT OBSTRUCTION USING A SELF-EXPANDING METAL STENT: STUDY PROTOCOL FOR A PROSPECTIVE EUROPEAN MULTICENTER TRIAL (PUMA TRIAL).

BackgroundEndoscopic ultrasound-guided biliary drainage (EUS-BD) was associated with better clinical success and a lower rate of adverse events (AEs) than fluoroscopy-guided percutaneous transhepatic biliary drainage (PTBD) in recent single center studies with mainly retrospective design and small case numbers (MethodsThe study is designed as a non

Two subpopulations of midbrain dopamine (DA) neurons are known to have different dynamic firing ranges in vitro that correspond to distinct projection targets: the originally identified conventional DA neurons project to the dorsal striatum and the lateral shell of the nucleus accumbens, whereas an atypical DA population with higher maximum firing

Abstract The reversible transformation of a nanohelix is one of the most exquisite and important phenomena in nature.However, nanomaterials usually fail to twist into helical crystals.Considering the irreversibility of the previously studied twisting forces, the reverse process (untwisting) is more difficult Body butter to achieve, let alone the re
