Electrochemical and Kinetic Performance of Low-Cobalt and Cobalt-Free Rare-Earth AB-Type Hydrogen Storage Alloys.

To address the high cost of cobalt in rare-earth hydrogen storage alloys, this study developed cost-effective low-cobalt and cobalt-free AB-type alloys. The results demonstrate that all synthesized alloys displayed a single-phase LaNi structure possessing a homogeneous elemental distribution. Low-cobalt (La, Ce) (Ni, Co, Mn, Al) alloy 4SC and cobalt-free (La, Ce) (Ni, Mn, Al) alloy 7D exhibited similarly excellent electrochemical performance, including high discharge capacity, long cycle life, and superior high-rate discharge () capability.

Mealtime alters daily rhythm in nuclear O-GlcNAc proteome to regulate hepatic gene expression.

The liver circadian clock and hepatic transcriptome are highly responsive to metabolic signals generated from feeding-fasting rhythm. Previous studies have identified a number of nutrient-sensitive signaling pathways that could interpret metabolic input to regulate rhythmic hepatic biology. Here, we investigated the role of O-GlcNAcylation, a nutrient-sensitive post-translational modification (PTM) in mediating metabolic regulation of rhythmic biology in the liver.

CAD-CAM of elastic plugs with multilayer porous channels following 3D construction of jaw cyst-mucosa-dentition after decompression: A dental technique.

This technique involves intraoral scanning of the dentition, open occlusal cone beam computed tomography (CBCT) of the jaw cyst, and digital data from the recording of the decompression window and adjacent teeth to construct 3-dimensional (3D) images of the jaw cyst-mucosa-dentition after decompression. Following the digital design of the crown, clasp arms, and multilayer porous channels, a plug with good retention, adequate drainage, and high patient satisfaction was digitally printed with elastic resins in a single visit.

Evaluating the effectiveness of a novel digital evaluation technology on dental preclinical crown preparation training.

Objectives: To evaluate the assessment scores of a novel digital training program versus traditional training in dental preclinical crown preparation.

Methods: Crown preparations in two consecutive preclinical training sessions were retrospectively collected and assigned to three groups: traditional group (TG), scanning group (SG), and digital evaluation group (DG). Students in the TG (n = 20) were taught by conventional visual grading, while students in the SG (n = 25) received three-dimensional feedback from digitally scanned preparations.

Digitally printed custom trays assembled with occlusion rims and gothic arch tracing devices attached with tenon-and-mortise joints for biofunctional complete dentures: A dental technique.

A novel technique of digitally printed custom trays assembled with occlusion rims and gothic arch tracing devices attached with tenon-and-mortise joints for biofunctional complete dentures that could be delivered in 2 visits is presented. This technique takes advantage of closed-mouth impressions and objective jaw relation records by following the biofunctional prosthetic system concept with high efficiency and reduced labor.

[Effects of Ethanol Extracts of Phellinus lonicerinus on Hepatic Stellate Cells of Fibrosis Liver in Rats].

Objective: To study the effects of ethanol extracts of Phellinus lonicerinus on hepatic stellate cells of fibrosis liver in rats.

Methods: The model rats of hepatic fibrosis were established by intraperitoneally injection of CCl₄ olive oil solution at the dose of 2 mL/kg. And then the model rats were administered orally ethanol extract of Phellinus lonicerinus with 1 g/(kg · d) and 0.

Estrogenic and anti-estrogenic activities of hispolon from Phellinus lonicerinus (Bond.) Bond. et sing.

Hispolon was the main antitumor active ingredient in Phellinus sensu lato species. In order to confirm the dual regulating estrogenic ingredient and obtain more effective natural estrogen replacement drugs, hispolon was separated from Phellinus lonicerinus (Bond.) Bond.
