The Influence of Circadian Rhythms on DNA Damage Repair in Skin Photoaging.

Circadian rhythms, the internal timekeeping systems governing physiological processes, significantly influence skin health, particularly in response to ultraviolet radiation (UVR). Disruptions in circadian rhythms can exacerbate UVR-induced skin damage and increase the risk of skin aging and cancer. This review explores how circadian rhythms affect various aspects of skin physiology and pathology, with a special focus on DNA repair.

Comparison of volumetric modulated arc therapy and helical tomotherapy for prostate cancer using Pareto fronts.

Background: Studies comparing different radiotherapy treatment techniques-such as volumetric modulated arc therapy (VMAT) and helical tomotherapy (HT)-typically compare one treatment plan per technique. Often, some dose metrics favor one plan and others favor the other, so the final plan decision involves subjective preferences. Pareto front comparisons provide a more objective framework for comparing different treatment techniques.

In Vivo Metabolic Imaging of [1- C]Pyruvate-d Hyperpolarized By Reversible Exchange With Parahydrogen.

Metabolic magnetic resonance imaging (MRI) using hyperpolarized (HP) pyruvate is becoming a non-invasive technique for diagnosing, staging, and monitoring response to treatment in cancer and other diseases. The clinically established method for producing HP pyruvate, dissolution dynamic nuclear polarization, however, is rather complex and slow. Signal Amplification By Reversible Exchange (SABRE) is an ultra-fast and low-cost method based on fast chemical exchange.

Palladium Nanoparticle-Loaded Mesostructural Natural Woods for Efficient Water Treatment.

Natural wood with oriented microchannels and unique multi-level structures is an ideal candidate for making water treatment membranes. Here, palladium nanoparticles are loaded into different kinds of natural woods and the degradation property of the wood membranes for organic pollutants are investigated. The water flux of hardwoods is significantly higher than that of softwood due to the existence of large vessel elements.

CQDs/biochar from reed straw modified Z-scheme MgInS/BiOCl with enhanced visible-light photocatalytic performance for carbamazepine degradation in water.

The application of environmental-friendly and sustainable green materials in constructing photocatalysts to degrade pharmaceuticals and personal care products (PPCPs) attracts more attention. Herein, biochar (BC) or biomass carbon quantum dots (CQDs) were used to modify MgInS/BiOCl (MB) heterojunction photocatalyst with Z-scheme structure, and improved the photocatalytic degradation performance for carbamazepine (CBZ) in the aqueous solution. Both BC and CQDs could form electron transfer interface with MB heterojunction, resulting in the photodegradation rate of MgInS/BiOCl/CQDs (MBC, 96.

A Universal Method for Enhancing the Structural Stability of Ni-Rich Cathodes Via the Synergistic Effect of Dual-Element Cosubstitution.

Ni-rich layered cathodes suffer detrimental structural changes due to irreversible phase transformation (IPT). Precisely surface structural reconstruction through foreign element doping is a potential method to alleviate IPT propagation. The structure of surface reconstructed layer is greatly determined by the foreign element content and species.

Visible-LED-light-driven photocatalytic degradation of ofloxacin and ciprofloxacin by magnetic biochar modified flower-like BiWO: The synergistic effects, mechanism insights and degradation pathways.

BiWO possesses good stability but poor photocatalytic activity under visible light. Herein, the coupling of BiWO, FeO and biochar (BiWO/FeO/BC) was investigated to enhance the photocatalytic performance of BiWO through facile hydrothermal method, which almost completely degraded ofloxacin (OFL) and ciprofloxacin (CIP) within 30 min under energy-saving visible LED irradiation. The superior photocatalytic activity of BiWO/FeO/BC was ascribed to the stronger visible light adsorption capacity and the lower recombination of electron-hole pairs.

Research on quantitative measurement method of articular cartilage thickness change based on MR image.

In order to study the quantitative measurement method of articular cartilage thickness change based on MR image, 140 patients with no knee joint symptoms and 17 patients with knee joint damage were studied. FLASH, SE and FISP 3 sequences were scanned for all normal knee joints to determine the articular cartilage thickness. 17 patients with knee joint damage were followed up for six months.

Improving the Structure Stability of LiNiCoMnO by Surface Perovskite-like LaNiLiO Self-Assembling and Subsurface La Doping.

The commercialization of high-capacity Ni-rich cathode LiNiCoMnO is still hindered by some defects, such as moderate rate property and inferior high-voltage cycling stability. The main reason is that the structural transformation starts at the surface from layered to spinel and then to the rock salt phase, which will be aggravated under a higher voltage and gradually spread to the bulk region during cycling. Here, we fabricate the LiNiCoMnO surface with the perovskite-like LaNiLiO, which possesses good thermostability and Li-ion diffusion kinetics, to strengthen its surface and subsurface lattice stability.

Construction of carbon-doped supramolecule-based g-CN/TiO composites for removal of diclofenac and carbamazepine: A comparative study of operating parameters, mechanisms, degradation pathways.

An eco-friendly 2D heterojunction photocatalyst composites (BCCNT) consisting of carbon-doped supramolecule-based g-CN (BCCN) layers and TiO nanoparticles has been fabricated via an in-situ method.

And the degradation efficiencies of DCF and CBZ could reach 98.
