This study aims to investigate the complications and patient-reported outcomes (PROs) following PMRT between direct-to-implant (DTI) and tissue expander-to-implant (TEI) reconstruction.

Methods: The retrospective study included breast cancer patients undergoing IBBR and PMRT.

CoP electrocatalysts embedded in nitrogen-doped carbon as a host toward fast iodine conversions.

Herein, well-dispersed cobalt phosphide (CoP) electrocatalysts embedded in nitrogen-doped carbon (CoP@NC) were developed as an iodine host for zinc iodine batteries. Benefiting from the high electrical conductivity of the carbon matrix and the strong interaction as well as the efficient electrocatalytic activity of CoP with iodine species, the host achieved rapid iodine conversion while effectively suppressing the formation of polyiodides and zinc dendrites.

Starfish-Inspired Solid-State Li-ion Conductive Membrane with Balanced Rigidity and Flexibility for Ultrastable Lithium Metal Batteries.

The performance of solid-state lithium-metal batteries (SSLMB) is often constrained by the low ionic conductivity, narrow electrochemical window, and insufficient mechanical strength of polyethylene oxide (PEO)-based electrolytes. Inspired by the soft-outside, rigid-inside structure of starfish, we designed multifunctional "starfish-type" composite polymer electrolytes (CPEs) using electrospinning technology. These CPEs feature a three-dimensional rigid skeleton network composed of polyacrylonitrile/metal-organic frameworks/ionic liquids (PAN/MOFs/ILs), creating continuous and efficient Li transport channels: MOFs impart rigidity, PEO acts as a cushioning outer layer to enhance interfacial compatibility, and ILs reduce interfacial resistance.

Innovation in CRC Research: Targeting SPACA6P-AS for Progression.

The purpose of this research was to provide light on the functional role that the long noncoding RNA SPACA6P-AS plays in the biology of colorectal cancer (CRC). The presence of elevated SPACA6P-AS expression in colorectal cancer tissues is linked to advanced stages of the disease as well as a decreased overall survival rate. It has been demonstrated through knockdown tests conducted on CRC cell lines that SPACA6P-AS stimulates cell growth in both in vitro and in vivo settings.

Engineering Magnetic Heterostructures with Synergistic Regulation of Charge-Transfer and Spin-Ordering for Enhanced Water Oxidation.

The design of heterojunctions offers a crucial solution for energy conversion and storage challenges, but current research predominantly focuses on charge transfer benefits, often neglecting spin attribute regulation despite the increasing recognition of spin-sensitivity in many chemical reactions. In this study, a novel magnetic heterostructure, CoFeO@CoFeMoO, is designed to simultaneously modulate charge and spin characteristics, and systematically elucidated their synergistic impact on the oxygen evolution reaction (OER). Experimental results and density functional theory calculations confirmed that the magnetic heterostructure exhibits both charge transfer and spin polarization.

Polarization: A Universal Driving Force for Energy, Environment, and Electronics.

The sustainable future relies on the synergistic development of energy, environmental, and electronic systems, founded on the development of functional materials by exploring their quantum mechanisms. Effective control over the distribution and behavior of charges within these materials, a basic quantum attribute, is crucial in dictating their physical, chemical, and electronic properties. At the core of charge manipulation lies "polarization"-a ubiquitous phenomenon marked by separating positive and negative charges.

Construction of 2D/2D Pd Metallene/COFs System with Strong Internal Electric Field for Outstanding Solar Energy Photocatalysis.

Due to the severe recombination of charge carriers, the photocatalytic activity of covalent organic frameworks (COFs) materials is limited. Herein, through simple ultrasound and stirring processes, the Pd metallene (Pde) is successfully combined with 2D COFs to form Pde/TpPa-1-COF (Pde/TPC) composites. Obviously, a strong internal electric field (IEF) is successfully formed in Pde/TPC hybrid materials, which significantly boosts the separation of photogenerated charges.

Effect of sodium selenite on the synthesis of glucosinolates and antioxidant capacity in Chinese cabbage ( L.ssp.).

Chinese cabbage ( ssp. ) is a globally cultivated and consumed leafy vegetable due to its abundant plant secondary metabolites and antioxidant compounds, including flavonoids, ascorbic acids, glucosinolates, and vitamins, which have been reported to confer health-promoting effects. Glucosinolates components in leaves of Chinese cabbage plantlets under different concentrations of sodium selenite (0, 30, and 50 μmol/L) were analyzed.

Enhancing photocatalytic performance of covalent organic frameworks via ionic polarization.

Covalent organic frameworks have emerged as a thriving family in the realm of photocatalysis recently, yet with concerns about their high exciton dissociation energy and sluggish charge transfer. Herein, a strategy to enhance the built-in electric field of series β-keto-enamine-based covalent organic frameworks by ionic polarization method is proposed. The ionic polarization is achieved through a distinctive post-synthetic quaternization reaction which can endow the covalent organic frameworks with separated charge centers comprising cationic skeleton and iodide counter-anions.

Creating Spin Channels in SrCoO through Trigonal-to-Cubic Structural Transformation for Enhanced Oxygen Evolution/Reduction Reactions.

Oxygen evolution and reduction reactions (OER and ORR) play crucial roles in energy conversion processes such as water splitting and air batteries, where spin dynamics inherently influence their efficiency. However, the specific contribution of spin has yet to be fully understood. In this study, we intentionally introduce a spin channel through the transformation of trigonal antiferromagnetic SrCoO into cubic ferromagnetic SrCoO, aiming to deepen our understanding of spin dynamics in catalytic reactions.

Triggering Asymmetric Layer Displacement Polarization and Redox Dual-Sites Activation by Inside-Out Anion Substitution for Efficient CO Photoreduction.

Sluggish bulk charge transfer and barren catalytic sites severely hinder the CO photoreduction process.

Tailoring d-Band Center of Single-Atom Nickel Sites for Boosted Photocatalytic Reduction of Diluted CO from Flue Gas.

Photocatalytic reduction of diluted CO from anthropogenic sources holds tremendous potential for achieving carbon neutrality, while the huge barrier to forming *COOH key intermediate considerably limits catalytic effectiveness. Herein, via coordination engineering of atomically scattered Ni sites in conductive metal-organic frameworks (CMOFs), we propose a facile strategy for tailoring the d-band center of metal active sites towards high-efficiency photoreduction of diluted CO. Under visible-light irradiation in pure CO, CMOFs with Ni-O sites (Ni-O CMOFs) exhibits an outstanding rate for CO generation of 13.

Methods: We employed an in vitro OGD/R model using H9C2 cells.

A free radical interlocking co-deposition strategy based on the oxidative pyrolysis mechanism of polyethylene terephthalate to achieve green energy recovery.

Accidental combustion and energy recovery of polyethylene terephthalate (PET) result in the formation of harmful organic substances and excessive emissions of CO and CO.

Overlooked Complexation and Competition Effects of Phenolic Contaminants in a Mn(II)/Nitrilotriacetic Acid/Peroxymonosulfate System: Inhibited Generation of Primary and Secondary High-Valent Manganese Species.

Organic contaminants with lower Hammett constants are typically more prone to being attacked by reactive oxygen species (ROS) in advanced oxidation processes (AOPs). However, the interactions of an organic contaminant with catalytic centers and participating ROS are complex and lack an in-depth understanding. In this work, we observed an abnormal phenomenon in AOPs that the degradation of electron-rich phenolics, such as 4-methoxyphenol, acetaminophen, and 4-presol, was unexpectedly slower than electron-deficient phenolics in a Mn(II)/nitrilotriacetic acid/peroxymonosulfate (Mn(II)/NTA/PMS) system.
