Introduction In the realm of Carotid Artery Stenting (CAS), various access methods such as Transfemoral access (TFA), Transradial Artery access (TRA), and Transbrachial access (TBA) have been employed. While TFA is widely established, TRA and TBA offer alternative options. TBA lacks comprehensive studies, and there is a notable lack of comprehensive evidence systematically evaluating its outcomes.

Combining Hard Shell with Soft Core to Enhance Enzyme Activity and Resist External Disturbances.

Adv Sci (Weinh)

Department of Cardiology, The First People's Hospital of Wenling, Wenling Hospital of Wenzhou Medical University, Wenling, Zhejiang, 317500, China.

Immobilizing enzymes onto solid supports having enhanced catalytic activity and resistance to harsh external conditions is considered as a promising and critical method of broadening enzymatic applications in biosensing, biocatalysis, and biomedical devices; however, it is considerably hampered by limited strategies. Here, a core-shell strategy involving a soft-core hexahistidine metal assembly (HmA) is innovatively developed and characterized with encapsulated enzymes (catalase (CAT), horseradish peroxidase, glucose oxidase (GOx), and cascade enzymes (CAT+GOx)) and hard porous shells (zeolitic imidazolate framework (ZIF), ZIF-8, ZIF-67, ZIF-90, calcium carbonate, and hydroxyapatite). The enzyme-friendly environment provided by the embedded HmA proves beneficial for enhanced catalytic activity, which is particularly effective in preserving fragile enzymes that will have been deactivated without the HmA core during the mineralization of porous shells.

Frontiers Science Center for Molecular Design Breeding, Beijing Key Laboratory of Crop Genetic Improvement, College of Agronomy and Biotechnology, China Agricultural University, Beijing, 100193, China.

Rice is highly sensitive to cold stress, particularly at the booting stage, which significantly threatens rice production. In this study, we cloned a gene, CTB6, encoding a lipid transfer protein involved in cold tolerance at the booting stage in rice, based on our previous fine-mapped quantitative trait locus (QTL) qCTB10-2. CTB6 is mainly expressed in the tapetum and young microspores of the anther.

Establishing the protein-protein interaction network sheds light on functional genomics studies by providing insights from known counterparts. However, the rice interactome has barely been studied due to the lack of massive, reliable, and cost-effective methodologies. Here, the development of a barcode-indexed PCR coupled with HiFi long-read sequencing pipeline (BIP-seq) is reported for high throughput Protein Protein Interaction (PPI)identification.

Bacterial infections, particularly those caused by drug-resistant bacteria, represent a pressing global health challenge. During the interaction between pathogen infection and host defense, bacterial infections initiate the host's immune response, which involves the activation of proteases that play a critical role in antibacterial defense. Granzyme B (GzmB), a key immune-related biomarker associated with cytotoxic T lymphocytes (CTLs), plays a pivotal role in this process.

Chiral and Quantum Plasmonic Sensors: New Frontiers in Selective and Ultra-Sensitive Sensing.

Small

January 2025

Department of Chemistry, Dr. Vishwanath Karad MIT World Peace University, Survey No, 124, Paud Rd, Kothrud, Pune, Maharashtra, 411038, India.

Surface Plasmon Polaritons (SPPs) and Localized Surface Plasmon Resonances (LSPRs) are fundamental phenomena in plasmonics that enable the confinement of electromagnetic waves beyond the diffraction limit. This confinement results in a significant enhancement of the electric field, making this phenomenon particularly beneficial for sensitive detection applications. However, conventional plasmonic sensors face several challenges, notably their difficulty in distinguishing chiral molecules, which are vital in drug development.

NHC Key Laboratory of Human Stem Cell and Reproductive Engineering, School of Basic Medical Sciences, Central South University, ChangSha, China.

An increasing number of patients utilizing in vitro fertilization (IVF) and assisted reproductive technology (ART) are characterized as impaired or poor ovarian responders (PORs). Owing to its unclear molecular etiology, the management of patients with age-related ovarian characteristics remains a controversial and complex clinical concern. Therefore, it is important to identify and understand the etiological causes behind POR to develop more effective and efficient management strategies for these patients.

State Key Laboratory of Advanced Medical Materials and Devices, Tianjin Key Laboratory of Neuromodulation and Neurorepair, Integrative regeneration laboratory, Institute of Biomedical Engineering, Chinese Academy of Medical Sciences & Peking Union Medical College, Tianjin, China.

Neuroinflammation plays a key role in the development of neurodegenerative diseases, with microglia regulating this process through pro-inflammatory M1 and anti-inflammatory M2 phenotypes. Studies have shown that human umbilical cord mesenchymal stem cells (hUCMSCs) modulate neuroinflammation by secreting anti-inflammatory cytokines. Photobiomodulation (PBM), a non-invasive therapy, has demonstrated significant potential in alleviating neuroinflammation.

January 2025

Institute for Cardiovascular Science & Department of Cardiovascular Surgery of the First Affiliated Hospital, State Key Laboratory of Radiation Medicine and Protection, Suzhou Medical College, Soochow University, Suzhou, Jiangsu, 215000, China.

Despite advancements in engineered heart tissue (EHT), challenges persist in achieving accurate dimensional accuracy of scaffolds and maturing human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), a primary source of functional cardiac cells. Drawing inspiration from cardiac muscle fiber arrangement, a three-dimensional (3D)-printed multi-layered microporous polycaprolactone (PCL) scaffold is created with interlayer angles set at 45° to replicate the precise structure of native cardiac tissue. Compared with the control group and 90° PCL scaffolds, the 45° PCL scaffolds exhibited superior biocompatibility for cell culture and improved hiPSC-CM maturation in calcium handling.

Leaky and structurally abnormal blood vessels and increased pressure in the tumor interstitium reduce the infiltration of CAR-T cells in solid tumors, including triple-negative breast cancer (TNBC). Furthermore, high burden of tumor cells may cause reduction of infiltrating CAR-T cells and their functional exhaustion. In this study, various effector-to-target (E:T) ratio experiments are established to model the treatment using CAR-T cells in leukemia (high E:T ratio) and solid tumor (low E:T ratio).

Bacterial keratitis (BK) is a type of corneal inflammation resulting from bacterial infection in the eye. Although nanozymes have been explored as promising materials in corneal wound healing, currently available nanozymes lack sufficient catalytic activity and the ability to penetrate bacterial biofilms, limiting their efficacy against the treatment of BK. To remedy this, ZnFe layered double hydroxide (ZnFe-LDH) nanosheets are loaded with Cu single-atom nanozymes (Cu-SAzymes) and aminated dextran (Dex-NH), resulting in the formation of the nanozyme DT-ZnFe-LDH@Cu, which possesses peroxidase (POD)-, oxidase (OXD)-, and catalase (CAT)-like catalytic activities.
