Reusable Te-Doped Sn-P-I Catalysts With Anti-Healing P Vacancies and Stable I Sites for Efficient Black Phosphorus Growth.

Black phosphorus (BP) holds significant potential for various applications, but its widespread use requires the development of efficient and cost-effective preparation methods. Sn-P-I clathrates are identified as potential catalysts for BP growth; however, the intact Sn-P-I structure leads to prolonged preparation times, rapid deactivation, and an unclear catalytic mechanism. In this study, a Te-doping strategy is proposed to simultaneously improve the activity and stability of Sn-P-I catalysts.

Rapid and Controllable Synthesis of Nanocrystallized Nickel-Cobalt Boride Electrode Materials via a Mircoimpinging Stream Reaction for High Performance Supercapacitors.

Nickel-cobalt borides (denoted as NCBs) have been considered as a promising candidate for aqueous supercapacitors due to their high capacitive performances. However, most reported NCBs are amorphous that results in slow electron transfer and even structure collapse during cycling. In this work, a nanocrystallized NCBs-based supercapacitor is successfully designed via a facile and practical microimpinging stream reactor (MISR) technique, composed of a nanocrystallized NCB core to facilitate the charge transfer, and a tightly contacted Ni-Co borates/metaborates (NCB ) shell which is helpful for OH adsorption.

Structural basis of indisulam-mediated RBM39 recruitment to DCAF15 E3 ligase complex.

The anticancer agent indisulam inhibits cell proliferation by causing degradation of RBM39, an essential mRNA splicing factor. Indisulam promotes an interaction between RBM39 and the DCAF15 E3 ligase substrate receptor, leading to RBM39 ubiquitination and proteasome-mediated degradation. To delineate the precise mechanism by which indisulam mediates the DCAF15-RBM39 interaction, we solved the DCAF15-DDB1-DDA1-indisulam-RBM39(RRM2) complex structure to a resolution of 2.

GC-Net: Global context network for medical image segmentation.

Background And Objective: Medical image segmentation plays an important role in many clinical applications such as disease diagnosis, surgery planning, and computer-assisted therapy. However, it is a very challenging task due to variant images qualities, complex shapes of objects, and the existence of outliers. Recently, researchers have presented deep learning methods to segment medical images.

Cryopreservation disrupts lipid rafts and heat shock proteins in yellow catfish sperm.

Lipid rafts and associated membrane proteins (flotillin, caveolin) play important roles in cell signaling and sperm fertilization while heat shock proteins (Hsp) ensure properly protein folding to fulfill their physiological functions. The markedly reduced fertility in thawed sperm after cryopreservation could result from disrupted membrane lipid rafts and these proteins. To explore the effect of sperm cryopreservation on lipid rafts and heat shock proteins, we compared lipid raft integrity, and the expression levels of lipid raft associated proteins (Flot-1, Flot-2, Cav-1) as well as heat shock proteins (Hsp90, Hsp70) in fresh and thawed sperm cryopreserved under different scenarios in yellow catfish.

Manganese oxide doping carbon aerogels prepared with MnO coordinated by N, N - dimethylmethanamide for supercapacitors.

Carbon aerogels with excellent conductive characteristics and high specific capacitance have attracted more and more interests for next-generation energy storage applications. Three-dimensional interconnected MnO/carbon aerogel supercapacitor electrodes are prepared by a novel doping method using MnO coordinated by N, N-dimethylmethanamide (DMF). The coordinative MnO (DMF/MnO) plays a key role in the sol-gel process of resorcinol and formaldehyde.

A Comparison of Electrochemical Performance of Carbon Aerogels with Adsorption Metal Ions for Super Capacitors.

Environmental problems caused by metal ions have caused widespread concern in recent years. In this work, carbon aerogels (CAs) adsorbing different metal ions were prepared.

Celecoxib targets breast cancer stem cells by inhibiting the synthesis of prostaglandin E and down-regulating the Wnt pathway activity.

Pharmacological targeting of breast cancer stem cells (CSCs) is highly promising for the treatment of breast cancer, as the small population of CSCs is responsible for tumor initiation, progression, recurrence and chemo-resistance. Celecoxib is one of the most commonly used non-steroidal anti-inflammatory drugs (NSAIDs), which have chemo-preventive activity against cancers, including breast cancer and colorectal cancer. However, the mechanisms by which NSAIDs exert its cancer prevention effects have yet been completely understood.

A fully enclosed, compact standard lightning impulse generator for testing ultra-high-voltage-class gas-insulated switchgears with high capacitance.

At present, conducting standard lightning impulse (LI) tests in the field for gas-insulated switchgear (GIS) equipment is difficult because of the high capacitance of the test equipment and large circuit inductance of traditional impulse devices, which leads to a wavefront time T(f) ≥ 2.5 μs. A novel fully enclosed, compact standard LI generator for testing ultra-high-voltage-class GIS equipment with high capacitance is presented to solve the problem of T(f) exceeding the standard during LI voltage tests for actual large-sized equipment.

Discovery of a novel series of potent non-nucleoside inhibitors of hepatitis C virus NS5B.

Hepatitis C virus (HCV) is a major global public health problem. While the current standard of care, a direct-acting antiviral (DAA) protease inhibitor taken in combination with pegylated interferon and ribavirin, represents a major advancement in recent years, an unmet medical need still exists for treatment modalities that improve upon both efficacy and tolerability. Toward those ends, much effort has continued to focus on the discovery of new DAAs, with the ultimate goal to provide interferon-free combinations.

E-health-oriented community health information system in china: our challenges, solution, and experience.

China has been implementing regional collaborative medical service (also known as e-health) for >5 years, but is still facing the challenges of bridging different community health information systems (CHISs).

Development and recent achievements of telemedicine in china.

Although China started to study and implement telemedicine much later than other advanced countries, telemedicine is developing very fast in this country. Research on telemedicine is also getting popular, and more and more teleconsultant systems are being carried out. For the purpose of assessing the development of telemedicine in China over these past 50 years, we conducted a study of three elements, namely (1) teleconsultations, (2) academic activities, and (3) education.
