Regulation of intestinal health by Lactobacillus rhamnosus GG during fasting-induced molting in laying hens.

This study aims to investigate the regulatory effects of adding Lactobacillus rhamnosus GG (LGG) during the fasting-induced molting (FIM) process on the intestinal mucosal barrier and microbiota of laying hens. A total of 288 houdan chickens of 420 days of age were randomly divided into four groups, with nine replicates in each group and each replicate containing eight chickens: NC group (no LGG added); TB group (LGG was added during the pre-fasting period (F0 period)); TF group (LGG was added during the fasting period (F15 period)); TBF group (LGG was added during both the pre-fasting and fasting periods). The FIM experiment focused on four key time points: F0, F15, the 5th day (R5), and the 30th day (R30) of refeeding.

Exploring the metabolic patterns and response mechanisms of bile acids during fasting: A study with poultry as an example.

Fasting is beneficial to alleviate fatty liver, lose weight and improve reproductive function. However, previous studies have shown that, during fasting, disorders of bile acid metabolism were strongly associated with intestinal inflammation. The physiological and biochemical parameters and gene expression of multiple tissues of chickens at every critical time node were measured by ELISA and qPCR.

Atmosphere Induces Tunable Oxygen Vacancies to Stabilize Single-Atom Copper in Ceria for Robust Electrocatalytic CO Reduction to CH.

Electrochemical carbon dioxide reduction (ECORR) shows great potential to create high-value carbon-based chemicals, while designing advanced catalysts at the atomic level remains challenging. The ECORR performance is largely dependent on the catalyst microelectronic structure that can be effectively modulated through surface defect engineering. Here, we provide an atmosphere-assisted low-temperature calcination strategy to prepare a series of single-atomic Cu/ceria catalysts with varied oxygen vacancy concentrations for robust electrolytic reduction of CO to methane.

Illiquidity Comovement and Market Crisis.

This paper presents a rational expectation equilibrium model to explore how the financial contagion occurs between the unlinked markets that do not share common fundamentals. In the proposed model, the authors assume two of the three risky assets share no common fundamental factors, but are connected by one intermediate asset via cross fundamentals. Through this channel, investors transmit fundamental risk from one asset to another by dint of the cross fundamentals.
