Mapping cells through time and space with moscot.

Single-cell genomic technologies enable the multimodal profiling of millions of cells across temporal and spatial dimensions. However, experimental limitations hinder the comprehensive measurement of cells under native temporal dynamics and in their native spatial tissue niche. Optimal transport has emerged as a powerful tool to address these constraints and has facilitated the recovery of the original cellular context.

Four Opportunities To Revitalize The US Biomedical Research Enterprise.

The US biomedical research enterprise is renowned for its historical and ongoing scientific breakthroughs and advancements. Yet its capacity to solve complex health issues, bridge health equity gaps, and strengthen public trust is constrained by the lack of an overarching national vision, fragmented coordination for research funding, and critical workforce recruitment and retention challenges. To improve national health outcomes and retain global competitiveness, the sector must embrace new approaches.

Hemorrhagic Shock Due to a Gastrointestinal Stromal Tumor in a Patient With Neurofibromatosis Type 1: A Case Report.

Gastrointestinal stromal tumors (GISTs), though rare, are associated with neurofibromatosis (NF) type 1 and may cause significant gastrointestinal bleeding. A 42-year-old male with NF1 presented with severe hematochezia and underwent initial non-contrast CT, which was negative for abnormalities. Subsequent endoscopies and PillCam studies also revealed no clear bleeding source.

Trochleoplasty Utilization in the Management of Patellofemoral Instability: Results From an International Survey of Surgeons.

Background: Considerable variability exists in the described clinical and radiographic indications for use, surgical techniques, postoperative management, and risk profile after trochleoplasty for the management of patellofemoral instability (PFI). In areas of clinical uncertainty, a cohesive summary of expert opinion and identification of areas of variation in current practice can be useful in guiding current practice and future research efforts.

Purpose: To assess the current indications for use, surgical techniques, postoperative rehabilitation practices, and observed complication profile for trochleoplasty in the management of PFI among surgeons who perform this procedure.
