- Abstract:
- ... Magnolia bark extract administered as a dietary supplement to poultry confers a performance and health benefit, but the mechanisms are unknown. Here, a metabolomics approach was used to identify changes in intestinal metabolite levels in chickens fed an unsupplemented diet or a diet supplemented with magnolia bark extract. Body weight gains of chickens fed magnolia bark-supplemented diets were inc ...

Before this, some local governments such as Nanjing Municipal Government had already relaxed the implementation of regulations for street food vending. The original purpose of allowing street food vending was to help e ...

After infection, CLas releases a set of effectors to modulate host responses. One of these critical effectors is Sec-delivered effector 1 (SDE1), which induces chlorosis and cell death in N. benthamiana. In this study, we ...

- Abstract:
- ... Texturing, i.e., preferentially oriented deposition of a film with a specific crystallographic direction, enables the manipulation of the charge transport properties and surface reactivity of photoelectrodes for solar water-splitting. The advancement of solar water-splitting systems under neutral conditions is a vital strategy to reduce the economic and ecological traits of the prevailing strong a ...

We used five groups of rats; control, (1 → 3)‐β‐D‐glucan (75 mg/kg), bortezomib group, bortezomib + (1 → 3)‐β‐D‐glucan groups (injection of (1 → 3)‐β‐D‐glucan after bortezomib and sacrificed at 48th or 72nd h). The effects of these substances were assessed by measuring th ...
