Heterogeneous Carbonylation of Alcohols on Charge-Density-Distinct Mo-Ni Dual Sites Localized at Edge Sulfur Vacancies.

Alcohols carbonylation is of great importance in industry but remains a challenge to abandon the usage of the halide additives and noble metals. Here we report the realization of direct alcohols heterogeneous carbonylation to carbonyl-containing chemicals, especially in methanol carbonylation, with a remarkable space-time-yield (STY) of 4.74 mol/kg/h and a durable stability as long as 100 h on Ni@MoS catalyst.

Synergistic effect of extracts on skin aging regulation. From predictions to outcome.

Intrinsic and extrinsic aging affect the health of human skin. Extracellular matrix protein degradation, DNA damage and oxidative stress are known to disturb skin architecture and skin homeostasis leading to skin aging. Traditional Chinese Medicine (TCM) delivers a large amount of knowledge regarding the phytotherapeutic power of diverse plants.

Response of serovar Typhimurium to alginate oligosaccharides fermented with fecal inoculum: integrated transcriptomic and metabolomic analyses.

Unlabelled: Alginate oligosaccharides (AOS), extracted from marine brown algae, are a common functional feed additive; however, it remains unclear whether they modulate the gut microbiota and microbial metabolites. The response of serovar Typhimurium, a common poultry pathogen, to AOS fermented with chicken fecal inocula was investigated using metabolomic and transcriptomic analyses. Single-strain cultivation tests showed that AOS did not directly inhibit the growth of .

Optical coherence tomography of the retina combined with color Doppler ultrasound of the tibial nerve in the diagnosis of diabetic peripheral neuropathy.

Objective: To investigate the value of the retinal nerve fiber layer (RNFL) thickness in the optic disc and the cross-sectional area (CSA) of lower limb nerves in the diagnosis of diabetic peripheral neuropathy (DPN) separately and in combination.

Methods: A total of 140 patients with type 2 diabetes were enrolled, including 51 patients with DPN (DPN group) and 89 patients without DPN (NDPN group). Clinical data and biochemical parameters were collected.

New method for the preparation of nonuniform distributed Co/SiO2 catalysts.

Egg-shell, egg-yolk and egg-white types of Co/SiO2 catalysts were prepared by utilizing entrapped air to inhibit the entrance of impregnation or leaching solution into the cores of catalyst pellets during the preparation procedure; the entrapped air played the important role because the capillary pressure was reduced to a suitable range by adjusting the concentration of ethanol in the impregnation or leaching solution for a hydrophobized silica surface.
