Engineering microstructures of Pt and understanding the related catalytic mechanism are critical to optimizing the performance for hydrogen evolution reaction (HER). Herein, Pt dispersion and coordination are precisely regulated on hierarchical nitrogen-doped carbon nanocages (hNCNCs) by a thermal-driven Pt migration, from edge-hosted Pt-NCl single sites in the initial Pt/hNCNC-70 °C catalyst to Pt clusters/nanoparticles and back to in-plane Pt-NC single sites. Thereinto, Pt-NCl presents the optimal HER activity (6 mV@10 mA cm) while Pt-NC shows poor HER activity (321 mV@10 mA cm) due to their different Pt coordination.

The leucine zipper-like transcriptional regulator 1 (LZTR1) gene has been reported to be associated with many kinds of human diseases, including cardiac disease, Noonan syndrome, and schwannomatosis. In this study, peripheral blood mononuclear cells (PBMCs) derived from patient diagnosed with dilated cardiomyopathy (DCM) was successfully reprogrammed into the human induced pluripotent stem cells (iPSCs) line, harboring a distinct heterozygous mutation in the LZTR1 gene. The established patient-derived iPSCs expressed endogenous pluripotent markers, demonstrated the potential to differentiate into three germ layers (endoderm, mesoderm, and ectoderm), and exhibited a normal karyotype.

Objective To explore the effects of proteasome 20S subunit beta 8 (PSMB8) on the proliferation,migration,and invasion of clear cell renal cell carcinoma (ccRCC) cells and whether PSMB8 promotes tumor progression by activating the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway. Methods The Cancer Genome Atlas was employed to analyze the mRNA levels of PSMB8 in ccRCC and normal tissue,and the expression levels of PSMB8 in ccRCC tissue and cells were determined by real-time quantitative PCR,Western blotting,and immunohistochemistry.Furthermore,the cell lines with stable overexpression and knockdown of PSMB8 were constructed.

Article Synopsis
  • - Sjögren's disease (SD) is an autoimmune condition linked to specific autoantibodies, and a case study showed that a previously healthy individual developed SD after primary Epstein-Barr virus (EBV) infection, resulting in multiple autoantibody productions.
  • - Researchers examined immune responses to various autoantigens and found that anti-Ro52 and anti-Ro60 autoantibodies started to appear shortly after EBV infection, with levels continuing to rise alongside other antibodies long after the initial infection.
  • - The study concludes that EBV infection can trigger specific autoantibody responses through different mechanisms, and it notes that some healthy individuals can produce certain autoantibodies independently of the EBV response.

Copper-containing intrauterine devices (Cu-IUD) are adopted by worldwide women for contraception with the advantages of long-term effectiveness, reversibility and affordability. However, adverse effects occur in the initial implantation stage of Cu-IUD in uterine because of the burst release of Cu. To minimize the burst release, in this study, we designed a series of Cu-Fe alloys with 0.

Laser technology is integral to the advancement of micro/nano-fabrication. While laser machining offers numerous advantages over alternative micro/nano-fabrication techniques, several challenges and bottlenecks continue to impede its large-scale industrial implementation. In response to these constraints, the molecular dynamics (MD) method has emerged as a formidable tool for optimizing the process parameters of laser micro/nano-fabrication and investigating alternative laser-based micro/nano-fabrication techniques.

: Circular RNA (circRNA) therapeutics hold great promise as an iteration strategy in messenger RNA (mRNA) therapeutics due to their inherent stability and durable protein translation capability. Nevertheless, the efficiency of RNA circularization remains a significant constraint, particularly in establishing large-scale manufacturing processes for producing highly purified circRNAs. Hence, it is imperative to develop a universal and more efficient RNA circularization system when considering synthetic circRNAs as therapeutic agents with prospective clinical applications.

Aqueous Zn battery is promising for grid-level energy storage due to its high safety and low cost, but dendrite growth and side reactions at the Zn metal anode hinder its development. Designing Zn with (002) orientation improves the stability of the Zn anode, yet grain boundaries remain susceptible to corrosion and dendrite growth. Addressing these intergranular issues is crucial for enhancing the electrochemical performance of (002)-textured Zn.

Chemotherapy and radiotherapy in combination with sequence regimens are recognized as the current major strategy for suppressing postoperative tumor recurrence. However, systemic side effects and poor in-field cooperation of the two therapies seriously impair the therapeutic efficacy of patients. The combination of brachytherapy and chemotherapy through innovative biomaterials has proven to be an important strategy to achieve synergistic effects of radiotherapy and chemotherapy in-time and in-field.

Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal cell carcinoma and has a poor prognosis. Despite the impressive advancements in treating ccRCC using immune checkpoint (IC) blockade, such as PD-1/PD-L1 inhibitors, a considerable number of ccRCC patients experience adaptive resistance. Therefore, exploring new targetable ICs will provide additional treatment options for ccRCC patients.

Plate fixation is a common treatment option for radial head fractures (RHFs). Due to the benefits of less invasiveness and fewer complications of internal fixation, the application of small-diameter headless compression screws (HCSs) to treat RHFs has become a new trend. This study aimed to compare the mechanical stability of four distinct internal fixation protocols for transversely unstable RHFs via finite element analysis.

Disruption of mitochondrial function is observed in multiple drug-induced liver injuries (DILIs), a significant global health threat. However, how the mitochondrial dysfunction occurs and whether maintain mitochondrial homeostasis is beneficial for DILIs remains unclear. Here, we show that defective mitophagy by OPTN (optineurin) ablation causes disrupted mitochondrial homeostasis and aggravates hepatocytes necrosis in DILIs, while OPTN overexpression protects against DILI depending on its mitophagic function.
