Anatomy of enzyme channels
2014

Conclusions: The majority of enzymes have buried active sites accessible via a network of access channels. ...
We find that over 64% of enzymes contain two or more long channels, their typical length being 28 Å. ...

Bile Duct Drainage Using a Short Double-Balloon Endoscope for a Hematoma due to Hepatocellular Carcinoma After Roux-en-Y Reconstruction
2015
Journal of Gastroenterology and Hepatology Research
Double-balloon ERCP enabled biliary drainage in a patient with surgically altered anatomy and cirrhosis, and provided effective relief of symptoms. CASE REPORT ...
A short double-balloon endoscope with a 2.8 mm working channel enabled metal stent placement. ...

Proof of C4 photosynthesis without Kranz anatomy in Bienertia cycloptera (Chenopodiaceae)
2002
The Plant Journal
Our results show Bienertia utilizes strict compartmentation of organelles and enzymes within a single cell to effectively mimic the spatial separation of Kranz anatomy, allowing it to function as a C 4 ...
Kranz anatomy, with its separation of elements of the C 4 pathway between two cells, has been an accepted criterion for function of C 4 photosynthesis in terrestrial plants. ...
We also thank the Electron Microscope Center of Washington State University for use of their facilities and staff assistance. ...

Benign biliary strictures treated with biodegradable stents in patients with surgically altered anatomy using double balloon enteroscopy
2020
Scandinavian Journal of Gastroenterology
Surgically altered anatomy complicates endoscopical procedures of pancreatobiliary tree. ...
The biodegradable stent, which can be passed through working channel of a long enteroscope, seems promising in the treatment of these strictures. The benefit is that no stent removal is needed. ...
The Archimedes stents were easily deployed through the long working channel (200 cm) of DBE. However, use of currently available ERCP devices is limited because of the long working channel. ...
