Background: Dixon-based magnetic resonance imaging (MRI) intramuscular proton density fat fraction (PDFF) is a potentially useful imaging biomarker of muscle quality. However, multi-vendor, multi-site reproducibility of intramuscular PDFF quantification, required for large clinical studies, can be strongly dependent on acquisition and processing. The purpose of this study was (I) to develop a 6-point Dixon MRI-based acquisition and processing technique for reproducible multi-vendor, multi-site quantification of thigh intramuscular PDFF; and (II) to evaluate the ability of the technique to detect differences in thigh muscle status between operated .

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

The 1957 H2N2 influenza pandemic virus [A(H2N2)pdm1957] has disappeared from humans since 1968, while H2N2 avian influenza viruses (AIVs) are still circulating in birds. It is necessary to reveal the recurrence risk and potential cross-species infection of these AIVs from avian to mammals. We find that H2 AIVs circulating in domestic poultry in China have genetic and antigenic differences compared to the A(H2N2)pdm1957.

Article Synopsis
  • Dual immune checkpoint blockade (ICB) using CTLA4 and PD-(L)1 inhibitors shows improved anti-tumor effectiveness and immune toxicity compared to PD-(L)1 inhibitors alone in advanced non-small-cell lung cancer (NSCLC) patients.
  • Patients with mutations in STK11 and/or KEAP1 genes benefit more from the combination treatment compared to those receiving only PD-(L)1 inhibitors, as shown in the POSEIDON trial.
  • The loss of KEAP1 serves as a strong predictor for the success of dual ICB, as it leads to a more favorable outcome by changing the tumor's immune environment to better engage CD4 and CD8 T cells for anti-tumor activity. *

Despite therapeutic efficacy observed with immune checkpoint blockade in advanced melanoma, many tumors do not respond to treatment, representing a need for new therapies. Here, we have generated chimeric antigen receptor (CAR) T cells targeting TYRP1, a melanoma differentiation antigen expressed on the surface of melanomas, including rare acral and uveal melanomas. TYRP1-targeted CAR T cells demonstrate antigen-specific activation and cytotoxic activity and against human melanomas independent of the MHC alleles and expression.

Introduction: Children with retinoblastoma have anesthesia for exams and treatment, but there is little information about how long treatment interventions (laser, cryotherapy, and intravitreal injections) add to routine exams under anesthesia (EUA). This information would be useful for planning operating room schedules, staff schedules, family expectations, and billing.

Methods: A retrospective, single-center, Institutional Review Board (IRB) approved review of anesthesia duration for retinoblastoma children undergoing EUA with laser, cryotherapy, or intravitreal injections performed at MSK between January 2019 and November 2023.
