Bone-Targeted Fluoropeptide Nanoparticle Inhibits NF-κB Signaling to Treat Osteosarcoma and Tumor-Induced Bone Destruction.

Osteosarcoma is a malignant bone cancer usually characterized by symptoms of bone loss due to pathologically enhanced osteoclast activity. Activated osteoclasts enhance bone resorption and promote osteosarcoma cell progression by secreting various cytokines. Intercepting the detrimental interplay between osteoclasts and osteosarcoma cells is considered as an option for osteosarcoma treatment.

We aimed to provide a comprehensive variants profile of the ATXN1, ATXN2, and ATXN3 genes and examine the association of these variants with the risk and clinical characteristics of ALS. We screened and analyzed the rare variants in a cohort of 2220 ALS patients from Southwest China, using controls from the Genome Aggregation Database (gnomAD) and the China Metabolic Analytics Project (ChinaMAP).

Miniaturized broadband high out-of-band rejection bandpass filter based on spoof surface plasmon polaritons with defected ground structure.

In this paper, a novel compact bandpass filter (BPF) with a wide out-of-band rejection is proposed. It can achieve broadband characteristics by combining hollow bowtie-type spoof surface plasmon polaritons (SSPPs) with complementary H-type defected grounded structures (DGSs) through aperture coupling. Compared with the conventional SSPP unit cells, the hollow bowtie-type structure exhibits much better slow-wave characteristics.

Monolayer MXO as potential 2D altermagnets and half-metals: a first principles study.

Realizing novel two-dimensional (2D) magnetic states would accelerate the development of advanced spintronic devices and the understandings of 2D magnetic physics. In this paper, we have examined the magnetic and electronic properties of 20 dynamically stable and exfoliable MXO (M = Ti-Ni; X = S-Te; excluding CoTeO). It has been unveiled that [XO]-and [M]-crystal fields govern the M-3orbital splittings in MXO.

Alarin regulates RyR2 and SERCA2 to improve cardiac function in heart failure with preserved ejection fraction.

Heart failure with preserved ejection fraction (HFpEF), a complex disease that is increasingly prevalent due to population aging, pose significant challenges in its treatment. The present study utilized the HFpEF rat model and H9C2 cells as research subjects to thoroughly investigate the potential mechanisms of alarin in protecting cardiac function in HFpEF. The study shows that under HFpEF conditions, oxidative stress significantly increases, leading to myocardial structural damage and dysfunction of calcium ion channels, which ultimately impairs diastolic function.

The results showed that two Ag(I) complexes bound to DNA by the intercalation mode and interacted with BSA using a static quenching procedure.

USP14 modulates cell pyroptosis and ameliorates doxorubicin-induced cardiotoxicity by deubiquitinating and stabilizing SIRT3.

This study investigates the role of the deubiquitinating enzyme USP14 in alleviating doxorubicin (DOX)-induced cardiotoxicity (DIC), particularly concerning its mechanism of regulating pyroptosis through the stabilization of the mitochondrial protein SIRT3. Using in vivo and in vitro models, the research demonstrated that USP14 overexpression protects against DOX-induced cardiac damage by modulating pyroptosis. Silencing SIRT3 via siRNA revealed that SIRT3 is a key intermediary molecule in USP14-mediated regulation of pyroptosis.
