Iron Oxide Nanoparticle-Based T Contrast Agents for Magnetic Resonance Imaging: A Review.

This review highlights recent progress in utilizing iron oxide nanoparticles (IONPs) as a safer alternative to gadolinium-based contrast agents (GBCAs) for magnetic resonance imaging (MRI). It consolidates findings from multiple studies, discussing current T contrast agents (CAs), the synthesis techniques for IONPs, the theoretical principles for designing IONP-based MRI CAs, and the key factors that impact their T contrast efficacy, such as nanoparticle size, morphology, surface modifications, valence states, and oxygen vacancies. Furthermore, we summarize current strategies to achieve IONP-based responsive CAs, including self-assembly/disassembly and distance adjustment.

Transparent and Antifouling Lubrication Coating for Medical Applications Formed by a Self-Assembled Method.

Lubrication surfaces reduce the risk of cross-contamination and enhance the long-term stability of medical devices, which holds significance in the realm of antifouling medical materials. However, the complexity of constructing micronano structures to immobilize lubricating fluids and the fluorine content typically found in silane coupling agents restrict their widespread adoption. In this study, we prepared a biomimetic lubricating coating (BLC) through the one-step self-assembly of octadecyltrichlorosilane and oil infusion.

DCAF13-mediated K63-linked ubiquitination of RNA polymerase I promotes uncontrolled proliferation in Breast Cancer.

Hyperactivation of ribosome biogenesis (RiBi) drives cancer progression, yet the role of RiBi-associated proteins (RiBPs) in breast cancer (BC) is underexplored. In this study, we perform a comprehensive multi-omics analysis and reveal that assembly and maturation factors (AMFs), a subclass of RiBPs, are upregulated at both RNA and protein levels in BC, correlating with poor patient outcomes. In contrast, ribosomal proteins (RPs) do not show systematic upregulation across various cancers, including BC.

Multicolored Bifacial Perovskite Solar Cells through Top Electrode Engineering.

Power generation and architectural beauty are equally important for designing efficient and esthetically appealing bifacial perovskite solar cells (PSCs). In this work, efficient and multicolored p-i-n-structured PSCs are achieved by taking advantage of a dielectric/metal/dielectric (DMD)-type (MoO/Ni/Ag/MoO) transparent counter electrode. The MoO/Ni underlayer effectively promotes the formation of a continuous and conductive ultrathin Ag transparent film, especially the 1 nm Ni seed layer adjusts the interface energy level between perovskite/MoO and Ag, resulting in Ohmic contact of the electrode to promote charge extraction and collection.

Here we present MedFound, a generalist medical language model with 176 billion parameters, pre-trained on a large-scale corpus derived from diverse medical text and real-world clinical records.

China's product-level CO emissions dataset aligned with national input-output tables from 1997 to 2020.

Carbon emission research based on input-output tables (IOTs) has received attention, but data quality issues persist due to inconsistencies between the sectoral scopes of energy statistics and IOTs. Specifically, China's official energy data are reported at the industry level, whereas IOTs are organized by product sectors. Valid IOT-based environmental models require consistent transformation from industry-level to product-level emissions.

Responses of intestinal microbiota to inulin was initial microbiota context dependent and affected by the supplementation dosage.

Evaluating the influence of human activities on flood severity and its spatial heterogeneity across the Pearl River Delta.

With climate change and intensified human activities, disasters such as heavy rainfall, flooding, typhoons, and storm surges are becoming more frequent, posing significant threats to lives, property, and economic development. We propose a method combining extreme value theory and probability distribution to examine the flood severity under the effect of strong human activities. By focusing on the Pearl River Delta (PRD), as one of the most populated areas of China, we quantified changes in the severity of extreme water level for different return levels between 1966 and 1990 and 1991-2016 (with strong human activities), associated with the spatial patterns over the PRD.

Building of CuO@Cu-TA@DSF/DHA Nanoparticle Targets MAPK Pathway to Achieve Synergetic Chemotherapy and Chemodynamic for Pancreatic Cancer Cells.

With the increase of reactive oxygen species (ROS) production, cancer cells can avoid cell death and damage by up-regulating antioxidant programs. Therefore, it will be more effective to induce cell death by using targeted strategies to further improve ROS levels and drugs that inhibit antioxidant programs. Considering that dihydroartemisinin (DHA) can cause oxidative damage to protein, DNA, or lipids by producing excessive ROS, while, disulfiram (DSF) can inhibit glutathione (GSH) levels and achieve the therapeutic effect by inhibiting antioxidant system and amplifying oxidative stress, they were co-loaded onto the copper peroxide nanoparticles (CuO) coated with copper tannic acid (Cu-TA), to build a drug delivery system of CuO@Cu-TA@DSF/DHA nanoparticles (CCTDD NPs).
