Glioblastoma multiforme (GBM) is characterized by pronounced immune escape and resistance to chemotherapy-induced apoptosis. Preliminary investigations revealed a marked overexpression of gasdermin E (GSDME) in GBM. Notably, cisplatin (CDDP) demonstrated a capacity of inducing pyroptosis by activating caspase-3 to cleave GSDME, coupled with the release of proinflammatory factors, indicating the potential as a viable approach of inducing anti-tumor immune activation.

Purpose: There are challenges in understanding the biomechanics of the human middle ear, and established methods for studying this system show significant limitations. In this study, we evaluate a novel dynamic imaging technique based on synchrotron X-ray microtomography designed to assess the biomechanical properties of the human middle ear by comparing it to laser-Doppler vibrometry (LDV).
Methods: We examined three fresh-frozen temporal bones (TB), two donated by white males and one by a Black female, using dynamic synchrotron-based X-ray microtomography for 256 and 512 Hz, stimulated at 110 dB and 120 dB sound pressure level (SPL).

Prion disease is a fatal neurodegenerative disease caused by the misfolding of prion protein (PrP) encoded by the PRNP gene. While there is currently no cure for the disease, depleting PrP in the brain is an established strategy to prevent or stall templated misfolding of PrP. Here we developed in vivo cytosine and adenine base strategies delivered by adeno-associated viruses to permanently modify the PRNP locus to achieve PrP knockdown in the mouse brain.

Transcription activators are said to stimulate gene expression by 'recruiting' coactivators, yet this vague term fits multiple kinetic models. To directly analyze the dynamics of activator-coactivator interactions, single-molecule microscopy was used to image promoter DNA, a transcription activator and the Spt-Ada-Gcn5 acetyltransferase (SAGA) complex within yeast nuclear extract. SAGA readily but transiently binds nucleosome-free DNA without an activator, while chromatin association occurs primarily when an activator is present.

Language-discordant healthcare encounters-when the patient/caregiver and clinician are not able to communicate directly in the patient's/caregiver's preferred language-are associated with worse quality of care, increased adverse events, and research exclusion. Here, we describe the current state of language justice in clinical practice and research in the United States, Canada, and Spain, discuss the role of social determinants of health and language, in patient safety and health outcomes and review an example of culturally and linguistically concordant interventions to increase research participation. We close with practical and global strategies to increase multilingual research participation and to provide equitable patient- and family-centered care in pediatric hematology-oncology.

Background: The multi-day Boston Remote Assessment of Neurocognitive Health (BRANCH) is a remote, web-based assessment designed to capture the earliest cognitive changes in the preclinical stage of Alzheimer's disease (AD). It has been validated in unimpaired older adults, but as individuals progress on the AD continuum, assessments need to remain feasible and valid at different clinical stages. The focus of this study was to assess feasibility and validity of multi-day BRANCH in participants with and without cognitive impairment.

A scalable, seven step synthesis is reported for a trifluoromethyl toluene protected sulfonated phenylalanine building block whose utility was demonstrated in the synthesis of four CXCR4-derived sulfonopeptides. When compared to a conventional trichloroethyl protected building block, overall yield was improved by up to 4-fold. We believe this building block will prove to be of significant value for the synthesis of a variety of peptide targets containing phenylalanine sulfonate, a bioisostere of tyrosine sulfate, enabling orthogonal protection strategies and improving synthetic efficiency and yield.

Itaconate is a metabolite catalyzed by cis-aconitate decarboxylase (ACOD1), which is mainly produced by activated macrophages and secreted into the extracellular environment to exert complex bioactivity. In the tumor microenvironment, itaconate is concentrated and induces an immunosuppressive response. However, whether itaconate can be taken up by tumor cells and its mechanism of action remain largely unclear.

Mosaic loss of Y (mLOY) is the most common somatic chromosomal alteration detected in human blood. The presence of mLOY is associated with altered blood cell counts and increased risk of Alzheimer disease, solid tumors, and other age-related diseases. We sought to gain a better understanding of genetic drivers and associated phenotypes of mLOY through analyses of whole-genome sequencing (WGS) of a large set of genetically diverse males from the Trans-Omics for Precision Medicine (TOPMed) program.

Preventive interventions are expected to substantially improve the prognosis of patients with primary liver cancer, predominantly hepatocellular carcinoma (HCC) and cholangiocarcinoma. HCC prevention is challenging in the face of the evolving etiological landscape, particularly the sharp increase in obesity-associated metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD). Next-generation anti-HCV and HBV drugs have substantially reduced, but not eliminated, the risk of HCC and have given way to new challenges in identifying at-risk patients.

Purpose Of Review: To increase knowledge of the natural history of recovery and long-term outcome following severe traumatic brain injury (sTBI).
Recent Findings: Recovery of consciousness and complex behaviors that presage subsequent functional recovery frequently occurs well beyond the first 7 days after injury, which is typically the time period widely used in the ICU for prognostic decision-making and establishing goals of care for. Similarly, recovery of functional independence occurs between 1 and 10 years postinjury in a substantial proportion of patients who do not recover command-following during the acute hospitalization.
