Combination of GLP-1 and sodium butyrate promote differentiation of pancreatic progenitor cells into insulin-producing cells.
We identified that nestin-EGFP-positive cells isolated by fluorescent-activated cell sorting (FACS) were downstream progenitor cells from colony-initiating pancreatic precursor cells. Under differentiation condition, these nestin-EGFP-positive cells could generate islet and neural ...

The influence of personality on neural mechanisms of observational fear and reward learning.
Fear and reward learning can occur through direct experience or observation. Both channels can enhance survival or create maladaptive behavior. We used fMRI to isolate neural mechanisms of observational fear and reward learning ...

Backward bifurcations in dengue transmission dynamics.
A deterministic model for the transmission dynamics of a strain of dengue disease, which allows transmission by exposed humans and mosquitoes, is developed and rigorously analysed. The model, consisting of seven mutually-exclusive compartments representing the human and vector dynamics, has ...

Higher expression of jejunal LPH gene in rats fed the high-carbohydrate/low-fat diet compared with those fed the low-carbohydrate/high-fat diet is associated with in vitro binding of Cdx-2 in nuclear proteins to its promoter regions.
It has been previously demonstrated that the expression of lactase-phlorizin hydrolase (LPH) ...

The importance of culling in Johne\'s disease control.
Johne\'s disease is caused by Mycobacterium avium subsp. paratuberculosis (MAP) infection and results in economic losses in the dairy industry. To control MAP transmission in herds, test-based culling has been recommended and immediate culling of high shedding animals ...

How quantitative measures unravel design principles in multi-stage phosphorylation cascades.
We investigate design principles of linear multi-stage phosphorylation cascades by using quantitative measures for signaling time, signal duration and signal amplitude. We compare alternative pathway structures by varying the number of phosphorylations and the length of ...

An S-type bypass can improve the hemodynamics in the bypassed arteries and suppress intimal hyperplasia along the host artery floor.
The development of distal end-to-side anastomotic intimal hyperplasia (IH) has been attributed to the flow disturbance and abnormal wall shear stress (WSS) distribution there. The geometry ...
