Transcription factor 7-like 2 gene links increased in vivo insulin synthesis to type 2 diabetes

open access: yesEBioMedicine, 2018
Transcription factor 7-like 2 (TCF7L2) is the main susceptibility gene for type 2 diabetes, primarily through impairing the insulin secretion by pancreatic β cells. However, the exact in vivo mechanisms remain poorly understood.

A General Procedure for Basic Kinematic Chain Formation and Topology Selection for Planar Mechanisms

open access: yesDesigns
In a complete kinematic synthesis process, a designer must select a planar linkage topology that is well suited to their problem situation. This involves weighing a set of competing priorities. For example, is it better to choose a simple topology like a
