Synergistic Enhancement of Antibacterial and Osteo-Immunomodulatory Activities of Titanium Implants via Dual-Responsive Multifunctional Surfaces.

Bone implant-associated infections and inflammations, primarily caused by bacteria colonization, frequently result in unsuccessful procedures and pose significant health risks to patients. To mitigate these challenges, the development of engineered implants with spatiotemporal regulation capabilities, designed to inhibit bacterial survival and modulate immune responses in the early stage, while promoting bone defect healing in the late stage is proposed. The implants are functionalized with ε-poly-l-lysine-phenylboronic acid (PP) via dynamic boronic ester bonds, which facilitate its release through a reactive oxygen species (ROS) and pH-responsive strategy, thereby establishing an antibacterial microenvironment on and around the implants.

A 2.9 Mb Chromosomal Segment Deletion Is Responsible for Early Ripening and Deep Red Fruit in .

Sweet orange () is an economically important fruit crop worldwide. Mining for genes associated with ripening periods and fruit color traits is crucial for plant genetics and for the improvement of external fruit quality traits. The present study identified a novel navel orange accession, designated as Ganhong, with early ripening and deep red fruit traits.

Whole-genome resequencing to investigate the genetic diversity and mechanisms of plateau adaptation in Tibetan sheep.

Introduction: Tibetan sheep, economically important animals on the Qinghai-Tibet Plateau, have diversified into numerous local breeds with unique characteristics through prolonged environmental adaptation and selective breeding. However, most current research focuses on one or two breeds, and lacks a comprehensive representation of the genetic diversity across multiple Tibetan sheep breeds. This study aims to fill this gap by investigating the genetic structure, diversity and high-altitude adaptation of 6 Tibetan sheep breeds using whole-genome resequencing data.

Isogeometric boundary element method analysis for dielectric target shape optimization in electromagnetic scattering.

In order to optimize the overall form of electromagnetic scattering in two-dimensional dielectric media, this work offers a frequency-domain boundary element method based on isogeometric analysis. The Isogeometric boundary element method (IGABEM) is used to guarantee geometric correctness during optimization and prevent over-refinement of the mesh. Non-uniform rational B-splines are used to discretize the boundary integrals of the model, enabling rapid numerical computation while ensuring high accuracy.

Enhancing low-dose radiotherapy efficacy with PARP inhibitors via FBL-mediated oxidative stress response in colorectal cancer.

The effectiveness of radiotherapy in colorectal cancer (CRC) relies on its ability to induce cell death via the generation of reactive oxygen species (ROS). However, genes responsible for mitigating oxidative stress can impede radiotherapy's efficacy. In this study, we elucidate a significant association between the nucleolar protein Fibrillarin (FBL) and the oxidative stress response in CRC tumors.

A self-regenerative heat pump based on a dual-functional relaxor ferroelectric polymer.

Electrocaloric (EC) cooling presents a promising approach to efficient and compact solid-state heat pumps. However, reported EC coolers have complex architectures and limited cooling temperature lift. In this work, we introduce a self-regenerative heat pump (SRHP) using a cascade of EC polymer film stacks, which have electrostrictive actuations in response to an electric field that are directed to realize efficient heat transfer, eliminating the need for additional transportive or regenerative mechanisms.

Tripartite motif 25 inhibits protein aggregate degradation during PRRSV infection by suppressing p62-mediated autophagy.

Viral infection causes endoplasmic reticulum stress and protein metabolism disorder, influencing protein aggregates formation or degradation that originate from misfolded proteins. The mechanism by which host proteins are involved in the above process remains largely unknown. The present study found that porcine reproductive and respiratory syndrome virus (PRRSV) infection promoted the degradation of intracellular ubiquitinated protein aggregates via activating autophagy.

Paclitaxel prodrug nanoparticles boost antitumor efficacy via hitchhiking of human serum albumin.

Improving drug delivery efficacy is the key point for enhancing the therapeutic index of medicines. Herein, we report fatty chain conjugated paclitaxel (PTX) prodrugs with a disulfide bond as linker. The formed prodrugs can self-assemble into stable nanoparticles in aqueous solutions, and rapidly transform into long-circulating nanocomplexes via the non-covalent binding to serum albumin in blood, enabling efficient drug delivery and robust antitumor effect.

Deformable Joule heating electrode based on hybrid layers of silver nanowires and carbon nanotubes and its application in a refreshable multi-cell Braille display.

Stretchable electrodes are an essential component in soft actuator systems. In particular, Joule heating electrodes (JHEs) are required for thermal actuation systems. A highly stretchable, patternable, and low-voltage operating JHE based on hybrid layers of silver nanowires (AgNWs) and carbon nanotubes (CNTs) is reported.

Transcriptome dataset of mouse adipose tissue across estrous cycles.

Adipose tissue is crucial for energy storage and release, ensuring energy homeostasis within the body. Disturbances in the physiology of adipose tissue have been associated with various health disorders, such as obesity and diabetes. The reproductive cycle represents a fundamental biological pattern in female physiology.

Protocol-Stipulated Dose Modification to Manage Chemotherapy-Induced Peripheral Neuropathy in Children, Adolescents, and Young Adults With High-Risk Hodgkin Lymphoma.

Purpose: Brentuximab vedotin (BV) incorporation into frontline chemotherapy regimens improved outcomes for classic Hodgkin lymphoma (cHL). The shared mechanism of action of BV and vinca alkaloids as microtubulin inhibitors increased the potential risk of chemotherapy-induced peripheral neuropathy (CIPN). Rates of CIPN and use of protocol-stipulated dose modifications of a microtubulin inhibitor were examined on the Children's Oncology Group AHOD1331 study, which compared BV, doxorubicin, vincristine (VCR), etoposide, prednisone, cyclophosphamide (BV-AVE-PC; BV arm) with bleomycin containing doxorubicin, bleomycin, vincristine, etoposide, prednisone, cyclophosphamide (ABVE-PC; standard arm) in patients with high-risk cHL ages 2-21 years.

Paclitaxel Prodrug Enables Glutathione Depletion to Boost Cancer Treatment.

Herein, we constructed a paclitaxel (PTX) prodrug (PA) by conjugating PTX with acrylic acid as a cysteine-depleting agent. The as-synthesized PA can assemble with diacylphosphatidylethanolamine-PEG to form stable nanoparticles (PA NPs). After endocytosis into cells, PA NPs can specifically react with cysteine and trigger release of PTX for chemotherapy.

Photobiomodulation ameliorates ovarian aging by alleviating oxidative stress and inflammation damage and improving mitochondrial function.
