Ultra-broadband light-absorbing materials are highly desired for effective solar-energy harvesting. Herein, novel cobalt phosphide double-shelled nanocages (CoP-NCs) are synthesized. Uniquely, these CoP-NCs are able to nonselectively absorb light spanning the full solar spectrum, benefiting from its electronic properties and hollow nanostructure. They promise a wide range of applications involving solar energy utilization. As proof-of-concept demonstrations, CoP-NCs are employed here as effective photothermal agents to ablate cancer cells by utilizing their ability of near-infrared heat conversion, and as photoactive material for self-powered photoelectrochemical sensing by taking advantage of their ability of photon-to-electricity conversion...

We previously demonstrated that chemopreventive methylselenocysteine (MSC) prevents N-Nitroso-N-methylurea (NMU)-induced mammary carcinogenesis in the susceptible Fischer 344 (F344) rats by enhancing NAD+-dependent SIRT1 activity, restoring circadian expression of Period 2 (Per2) and circadian controlled genes. Here, we show that compared to the genetically resistant Copenhagen (COP) rat strain, mammary glands of the F344 rats have a 4-hour phase delay in circadian expression of Per2. Consequently, F344 rats failed to increase SIRT1 activity and circadian expression of Per2 and DDRR genes after exposure to NMU...

Transition metal phosphide (TMP) nanostructures have stimulated increasing interest for use in water splitting owing to their abundant natural sources and high activity for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Typically, the preparation of hierarchical TMPs involves the utilization of expensive or dangerous phosphorus sources, and, in particular, the understanding of topotactic transformations of the precursors to crystalline phases-which could be utilized to enhance electrocatalytic performance-remains very limited...

It has been reported that the elderly use co-contraction of the tibialis anterior (TA) and plantarflexor muscles for longer duration during quiet standing than the young. However, the particular role of ankle muscle co-contractions in the elderly during quiet standing remains unclear. Therefore, the objective of this study was to investigate the association between ankle muscle co-contractions and postural steadiness during standing in the elderly. Twenty-seven young (27.2±4.5yrs) and twenty-three elderly (66...

BACKGROUND: Lack of early diagnosis methods and the development of drug resistance are among the main reasons for increased mortality rates within breast cancer patients. These two aspects are governed by specific pro-carcinogenic modifications, where TGBß-induced EMT is one of the leading actors. Endowment of the epithelial cells with mesenchymal characteristics allows them to migrate and invade secondary tissues in order to form malignant sites and also confers chemoresistance. TGFß which role switches from the tumor suppressor cytokine to the oncogenic one favoring the tumor microenvironment regulates this process...

A rapid and sensitive HPLC-APCI-MS/MS method for the determination of cholesterol oxidation products (COPs) in milk powder based foods is reported. The method consists in the direct saponification of the sample and purification of oxysterols by reversed phase C18-SPE followed by HPLC-MS/MS analysis. By this procedure, the extraction and enrichment of oxysterols are combined in a unique step, reducing sample manipulation and the possible formation of artifacts. LOD and LOQ were in the concentration ranges of 2-8ngg(-1) and 8-30ngg(-1), respectively...

Production of hydrogen from water electrolysis has stimulated the search of sustainable electrocatalysts as possible alternatives. Recently, cobalt phosphide (CoP) and molybdenum phosphide (MoP) received great attention owing to their superior catalytic activity and stability towards the hydrogen evolution reaction (HER) which rivals platinum catalysts. In this study, we synthesize and study a series of catalysts based on hybrids of CoP and MoP with different Co/Mo ratio. The HER activity shows a volcano shape and reaches a maximum for Co/Mo = 1...

Shear wave elastography (SWE) was performed independently by two radiologists in 264 solid breast masses. The images were reviewed for color overlay pattern (COP) classification by the two radiologists, double blinded to any information. The interobserver agreement of the COP was almost perfect (κ=0.908) and high in Emax (ICC=0.89). The AUC value of the COP (0.954) was significantly higher than that of Emax (0.915) (p=0.002) but not significantly different from that of Emax combined with COP (0.957) (p=0.098)...
