Object: To investigate the effects of Shen Qi Bu Qi Powder (SQBQP) on the average daily gain, blood indexes, gastrointestinal microflora, and serum metabolites of calves.

Methods: A total of 105 calves were randomly assigned to three groups (n = 35 per group): the control group (C, fed with a basal diet for 21 days) and two treatment groups (SQBQP-L and SQBQP-H, fed with the basal diet supplemented with 15 and 30 g/kg of SQBQP), respectively for 21 days. The active components of SQBQP were identified using LC-MS/MS.

Integrated "all-in-one" strategy to construct highly efficient Pd catalyst for CO transformation.

The synthesis of high-value chemicals featuring C-C and/or C-heteroatom bonds CO is critically important, yet efficiently converting thermodynamically stable and kinetically inert linear CO and propargylic amine to the heterocyclic compound 2-oxazolidinone with an integrated catalytic system continues to pose a considerable challenge. Herein, we have designed an "all-in-one" (AIO) palladium (Pd) catalyst (Cat1), distinguished by its co-coordination with acetylglucose (AcGlu) and bis(benzimidazolium) units at the Pd center, which promotes the cyclization of CO and propargylic amine achieving a highest turnover frequency (TOF) of up to 3456 h. Moreover, Cat1 demonstrates excellent stability across various temperatures, with its catalytic activity remaining unchanged even after 10 cycles.

Base-Mediated Chemodivergent [4 + 1] and [2 + 1] Cycloadditions of -Alkylpyridiniums and Enones.

Divergent synthesis of structurally different products from the same kinds of starting materials is highly synthetically useful but very challenging. Herein, we reported a base-mediated chemodivergent [4 + 1] and [2 + 1] cycloaddition of -alkylpyridinium and enone under mild conditions, leading to furan-fused bicycles with high diastereoselectivity and spirobicycles, respectively, from moderate to high yields. -Alkylpyridinium salts were modular nucleophilic transfer reagents and C1 synthons, which underwent tandem Michael addition to the α,β-unsaturated ketones and cyclization under the base conditions.

Highly Self-Healing Co/Ni Dual-Active Species for the Electrocatalytic Oxidation of 5-Hydroxymethylfurfural.

Electrocatalytic conversion of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is significant for the sustainable production of value-added chemicals. Active sites of catalysts could enhance the activity and selectivity of the HMF oxidation reaction (HMFOR), but the self-healing ability of active sites has been commonly ignored. In this work, Co(OH)/Ni-MOF was successfully fabricated for efficient oxidation of HMF to FDCA under mild conditions.

The process utilises the inherent moisture of Moso bamboo shoots, coupled with a low amount of KOH, to form potassium organic salts before drying.

Progress towards understanding the effects of artificial light on the transmission of vector-borne diseases.

Artificial light at night (ALAN) is a common form of light pollution worldwide, and the intensity, timing, duration, and wavelength of light exposure can affect biological rhythms, which can lead to metabolic, reproductive, and immune dysfunctions and consequently, host-pathogen interactions. Insect vector-borne diseases are a global problem that needs to be addressed, and ALAN plays an important role in disease transmission by affecting the habits and physiological functions of vector organisms. In this work, we describe the mechanisms by which ALAN affects host physiology and biochemistry, host-parasite interactions, and vector-borne viruses and propose preventive measures for related infectious diseases to minimize the effects of artificial light on vector-borne diseases.

Air-Stable High-Entropy Layered Oxide Cathode with Enhanced Cycling Stability for Sodium-Ion Batteries.

O3-type layered oxides have been extensively studied as cathode materials for sodium-ion batteries due to their high reversible capacity and high initial sodium content, but they suffer from complex phase transitions and an unstable structure during sodium intercalation/deintercalation. Herein, we synthesize a high-entropy O3-type layered transition metal oxide, NaNiCuFeMnMgTiO (NCFMMT), by simultaneously doping Cu, Mg, and Ti into its transition metal layers, which greatly increase structural entropy, thereby reducing formation energy and enhancing structural stability. The high-entropy NCFMMT cathode exhibits significantly improved cycling stability (capacity retention of 81.

Compressed ternary alloy superhydrides are currently considered to be the most promising competitors for high-temperature superconducting materials. Here, the stable stoichiometries in the Y-Hf-H ternary system under pressure are comprehensively explored in theory and four fresh phases are predicted: Pmna-YHfH and P4/mmm-YHfH at 200 GPa, P4/mmm-YHfH at 300 GPa and P-6m2-YHfH at 400 GPa. The four Y-Hf-H ternary phases are thermodynamically and dynamically stable at corresponding pressure.
