We previously reported that the DNA alkylator and transcriptional-blocking chemotherapeutic agent trabectedin enhances oncolytic herpes simplex viroimmunotherapy in human sarcoma xenograft models, though the mechanism remained to be elucidated. Here we report trabectedin disrupts the intrinsic cellular antiviral response which increases viral transcript presence in the human tumor cells. We also extended our synergy findings to syngeneic murine sarcoma models, which are poorly susceptible to virus infection.

MnO nanowires coated with conjugated microporous polymers (CMP) are applied as triboelectric energy harvesting materials. The tribopositive performance of the CMP shells is enhanced with the assistance of MnO nanowires (MnO NW), likely due to cationic charge transfer from the tribopositive CMP layers to the surface Mn and Mn species of MnO NW. This is supported by model studies.

Article Synopsis
  • Normal tissues adjacent to breast tumors (NATs) may contain early signs of breast cancer development due to a phenomenon called field cancerization.
  • A study using advanced genomic techniques on samples from 43 breast cancer patients in Hong Kong revealed that NATs often had single-nucleotide variants (SNVs) in driver genes also found in tumor samples, but rarely had large-scale genomic changes.
  • The researchers identified different evolutionary patterns among NAT and tumor pairs, indicating distinct genomic characteristics and the influence of the tumor microenvironment on cancer development.

The effects of violent mixing and reactor geometric conditions were investigated using the overhead stirrer and high-speed homogenizer in 28-kHz sonoreactors. The sonochemical oxidation activity was quantified using the KI dosimetry method, and the sonochemical active zone was visually observed using the luminol method. Higher mixing rates resulted in a significant enhancement of the sonochemical oxidation activity, primarily due to a significant change in the sonochemical active zone.

The coming decades will see a substantial increase in the population of older adults, accompanied by significant demographic and family structure changes worldwide. As a result, the empty nest period-the postparental phase in parents' lives when their children have left home and they are no longer engaged in childrearing-is becoming an increasingly common experience in Western and Asian cultures. The current theoretical review examines the psychological consequences of the empty nest period on loneliness and well-being across cultures, emphasizing the impact of cultural factors on these experiences.

Article Synopsis
  • Advanced prostate cancer treatment struggles due to a lack of effective therapies, emphasizing the need to understand the molecular mechanisms of therapeutic resistance and identify potential drug targets.
  • The study utilized ATAC-seq data to analyze chromatin accessibility differences between drug-responsive (Remission) and drug-resistant (Disease) prostate cancer groups, revealing a significant link between chromatin accessibility, transcriptional output, and transcription factor (TF) activity.
  • Among the identified TFs, FOXM1 showed high activity in drug-resistant cells; knockdown of FOXM1 led to reduced cell proliferation and increased sensitivity to treatment, highlighting its role in therapeutic resistance and paving the way for future research on overcoming drug resistance in prostate cancer.

Positron emission tomography (PET) is the most sensitive biomedical imaging modality for non-invasively detecting and visualizing positron-emitting radiopharmaceuticals within a subject. In PET, measuring the time-of-flight (TOF) information for each pair of 511-keV annihilation photons improves effective sensitivity but requires high timing resolution. Hybrid materials that emit both scintillation and Cherenkov photons, such as bismuth germanate (BGO), recently offer the potential for more precise timing information from Cherenkov photons while maintaining adequate energy resolution from scintillation photons.
