In situ detection of individual classical MHC-I gene products in cancer.

Tumor-specific HLA class I expression is required for cytotoxic T-cell elimination of cancer cells expressing tumor-associated or neo-antigens. Cancers downregulate antigen presentation to avoid adaptive immunity. The highly polymorphic nature of the genes encoding these proteins, coupled with quaternary-structure changes after formalin fixation, complicate detection by immunohistochemistry.

Flat-Band AC Transport in Nanowires.

The electronic states in flat bands possess zero group velocity and null charge mobility. Recently, flat electronic bands with fully localized states have been predicted in nanowires, when their hopping integrals between first, second, and third neighbors satisfy determined relationships. Experimentally, these relationships can only be closely achieved under external pressures.

Reversion of metabolic dysfunction-associated steatohepatitis by skeletal muscle-directed FGF21 gene therapy.

The highly prevalent metabolic dysfunction-associated steatohepatitis (MASH) is associated with liver steatosis, inflammation, and hepatocyte injury, which can lead to fibrosis and may progress to hepatocellular carcinoma and death. New treatment modalities such as gene therapy may be transformative for MASH patients. Here, we describe that one-time intramuscular administration of adeno-associated viral vectors of serotype 1 (AAV1) encoding native fibroblast growth factor 21 (FGF21), a key metabolic regulator, resulted in sustained increased circulating levels of the factor, which mediated long-term (>1 year) MASH and hepatic fibrosis reversion and halted development of liver tumors in obese male and female mouse models.

Co-created improvement goals and strategies for implementing SBIRT and MAUD in primary care settings in a facilitator-supported, tailored implementation study.

Evidence-based approaches to screening and treatment for unhealthy alcohol use have the potential to reduce morbidity and mortality but are currently underutilized in primary care settings. To support implementation of screening, brief intervention, and referral to treatment (SBIRT) and medication-assisted treatment for alcohol use disorder (MAUD) by identifying goals co-developed by clinics and practice facilitators in a flexible implementation study. In a pragmatic implementation study, we used practice facilitation to support the implementation of SBIRT and MAUD in 48 clinical practices across Oregon, Washington, and Idaho.

Roadmap to a Global Template for Implementation of Ototoxicity Management for Cancer Treatment.

Ototoxicity is among the adverse events related to cancer treatment that can have far-reaching consequences and negative impacts on quality-of-life for cancer patients and survivors of all ages. Ototoxicity management (OtoM) comprises the prevention, diagnosis, monitoring, and treatment, including rehabilitation and therapeutic intervention, of individuals who experience hearing loss, tinnitus, or balance/vestibular difficulties following exposures to ototoxic agents, including platinum chemotherapy (cisplatin, carboplatin) and cranial radiation. Despite the well-established physical, socioeconomic, and psychological consequences of hearing and balance dysfunction, there are no widely adopted standards for clinical management of cancer treatment-related ototoxicity.
