The discovery of nanozymes has opened new possibilities for tumor therapy. However, their reliance on the tumor microenvironment and limited catalytic efficiency hinder broader applications. In this study, ruthenium-phenanthroline nanoparticles (Ru-Phs) are synthesized by combining ruthenium with phenanthroline and subsequently coloaded with the proton pump inhibitor (PPI) pantoprazole into sodium alginate (ALG) to form a Ru-Phs-PPI-ALG hydrogel for in situ tumor therapy.

The dura trauma or large defects due to neurosurgical procedures can result in potential complications. Dural replacements have proven effective to reduce the risk of seizures, meningitis, cerebrospinal fluid leakage, cerebral herniation, and infection. Although various artificial dural patches have been developed, addressing iatrogenic infections and cerebral adhesions resulting from patches implantation remains a challenge.

Multi-criteria decision-making (MCDM) methods have been extensively employed by researchers in the public transport (PT) sector. While many studies utilize a single MCDM method, employing multiple MCDM methods can achieve more robust results. Furthermore, integrated MCDM methods have the potential to address the weaknesses and limitations inherent in single MCDM method.

Oral ulcers, the most common type of mucosal lesion, are both highly prevalent and prone to recurrence. In the persistently moist environment of the oral cavity, current therapeutic patches face challenges such as short adhesion time, disruption by food particles and bacteria, and oral movements. To address these challenges, we develop a Janus patch, named ANSB, inspired by the multi-layered and asymmetric structure of natural mucosa, featuring a long-lasting adhesive layer and a lubricating layer.

This study employs the Stimulus-Organism-Response (SOR) model to construct a new mediation framework, examining the impact of Chinese stand-up comedians' language on audience engagement from both quantitative and qualitative perspectives. Statistical analysis of data from 415 online viewers of stand-up comedy shows revealed that comedians' humorous language significantly enhanced audience engagement by positively influencing their enjoyment. Based on this, in-depth interviews were conducted with 8 viewers to understand their specific perceptions of different types of humor.

Article Synopsis
  • Ulcerative colitis (UC) is exacerbated by excessive reactive oxygen/nitrogen species and inflammatory cytokines, creating a challenging inflammatory environment for treatment.
  • Traditional drugs for UC often lead to side effects, resistance, and low patient compliance, highlighting the need for safer and more effective therapies.
  • Recently developed manganese gallate nanoparticles show promise as a nontoxic nanoenzyme that alleviates UC symptoms by reducing inflammation, restoring gut barrier function, and improving intestinal microbiota balance.

Article Synopsis
  • A 54-year-old postmenopausal woman requested the removal of her IUD, which had been in place for over twenty years.
  • The IUD was embedded and required a hysteroscopic examination and removal, which also revealed additional uterine content.
  • For postmenopausal women with IUDs, early removal is advised to prevent complications, and hysteroscopic procedures are recommended for dealing with embedded devices.

Article Synopsis
  • Ferroptosis is highlighted as a type of cell death linked to inflammatory skin conditions, but its role in allergic contact dermatitis (ACD) is not well understood.
  • The study aimed to understand how ferroptosis contributes to ACD using a mouse model, focusing on different cell types and employing a treatment to inhibit this process.
  • Results showed that ferroptosis was particularly significant in immune cells like neutrophils and CD8 T cells, and using a ferroptosis inhibitor improved skin inflammation and reduced cell death in ACD mice.

  • - The study investigates the effects of He's Yangchao formula (HSYC), a compound made of eight herbs, on enhancing ovarian function and combating female reproductive aging, a growing public health concern.
  • - Researchers conducted experiments on naturally aged mice, assessing ovarian aging through various biological techniques and analyzing gut microbiota, metabolome, and transcriptome to uncover HSYC's mechanisms.
  • - Results showed HSYC improved follicular development and mitigated age-related dysfunctions by enhancing glutathione metabolism, which is crucial for countering ovarian aging, and enriching beneficial gut bacteria.

Structural variation heavily influences the molecular landscape of cancer, in part by impacting DNA methylation-mediated transcriptional regulation. Here, using multi-omic datasets involving >2400 pediatric brain and central nervous system tumors of diverse histologies from the Children's Brain Tumor Network, we report hundreds of genes and associated CpG islands (CGIs) for which the nearby presence of somatic structural variant (SV) breakpoints is recurrently associated with altered expression or DNA methylation, respectively, including tumor suppressor genes ATRX and CDKN2A. Altered DNA methylation near enhancers associates with nearby somatic SV breakpoints, including MYC and MYCN.

The acoustically actuated nanomechanical magnetoelectric (ME) antennas represent a promising new technology that can significantly reduce antenna size by 1-2 orders of magnitude compared to traditional antennas. However, current ME antennas face challenges such as low antenna gain and narrow operating bandwidth, limiting their engineering applications. In this paper, we enhance the bandwidth and radiation performance of ME antennas through structural optimization, leveraging theoretical analysis and numerical simulations.

Chemodynamic therapy (CDT) involving the use of metal nanozymes presents new opportunities for the treatment of deep-seated tumors. However, the lower ROS catalytic rate and dependence on high HO concentrations affect therapeutic efficacy. To address this issue, a hydrogel was constructed for the treatment of osteosarcoma by combining Cu-FeO nanozymes (NCs) and artemisinin (AS) coencapsulated in situ with sodium alginate (ALG) and calcium ions.

Background: The differential gene expression profile of metastatic versus primary breast tumors represents an avenue for discovering new or underappreciated pathways underscoring processes of metastasis. However, as tumor biopsy samples are a mixture of cancer and non-cancer cells, most differentially expressed genes in metastases would represent confounders involving sample biopsy site rather than cancer cell biology.

Methods: By paired analysis, we defined a top set of differentially expressed genes in breast cancer metastasis versus primary tumors using an RNA-sequencing dataset of 152 patients from The Breast International Group Aiming to Understand the Molecular Aberrations dataset (BIG-AURORA).

ONC201 (originally discovered as TRAIL-Inducing Compound #10 or TIC10) and analogue ONC206 have been found to induce an integrated stress response with suggested primary targets and mechanisms involving targeting mitochondrial protein ClpP and antagonism of dopamine receptors D2/3 (DRD2/3). We hypothesized that dopamine, the agonist of DRD2, may counteract ONC201 or ONC206 for DRD2/3 and impair the anti-cancer effect of ONC201 or ONC206, thus protect the tumor cells from the cytotoxic effect of ONC201 or ONC206. We therefore pre-treated cancer cells from different tissue origins including breast cancer, pancreatic cancer, colorectal cancer, and diffuse midline glioma (DMG) with dopamine, followed by treatment of ONC201, ONC206 or ONC212.
