Hominin presence in Eurasia by at least 1.95 million years ago.

The timing of the initial dispersal of hominins into Eurasia is unclear. Current evidence indicates hominins were present at Dmanisi, Georgia by 1.8 million years ago (Ma), but other ephemeral traces of hominins across Eurasia predate Dmanisi.

Dynamic allostery in the peptide/MHC complex enables TCR neoantigen selectivity.

The inherent antigen cross-reactivity of the T cell receptor (TCR) is balanced by high specificity. Surprisingly, TCR specificity often manifests in ways not easily interpreted from static structures. Here we show that TCR discrimination between an HLA-A*03:01 (HLA-A3)-restricted public neoantigen and its wild-type (WT) counterpart emerges from distinct motions within the HLA-A3 peptide binding groove that vary with the identity of the peptide's first primary anchor.

Comparative analysis of bacterial microbiota in Aedes aegypti (Diptera: Culicidae): insights from field and laboratory populations in Colombia.

Comparative studies of the microbiota in whole-body mosquitoes from natural populations and laboratory-reared specimens are scarce, particularly in tropical countries like Colombia, where understanding microbial patterns is critical for effective disease control and vector management. This study examines the bacterial microbiota of Aedes aegypti by comparing field-collected mosquitoes from 3 Colombian regions (Southern Amazon, Central Andean region, and Northern Caribbean coast) with laboratory strains (Rockefeller, Otanche, and Tolima). These regions are highly endemic for dengue and are associated with lineage 1 of Ae.

Sympathetic nerve signaling rewires the tumor microenvironment: a shift in "microenvironmental-ity".

Nerve signaling within the tumor microenvironment (TME) plays a critical role in the initiation, progression, and metastasis of solid tumors. Due to their highly responsive behavior and activation upon injury and cancer onset, this review specifically focuses on how sympathetic nerves rewire the TME. Within tumors, sympathetic nerves closely interact with various TME components, and their combined signaling often shifts tumor-intrinsic physiology toward tumor-supportive phenotypes.

Multi-Institutional Analysis of Pancreatoduodenectomy for Nonfamilial Periampullary Adenoma: A Novel Risk Score to Guide Shared Decision-Making.

Introduction: Pancreatoduodenectomy (PD) may occasionally be indicated for complete removal of periampullary (duodenal and ampullary) adenomas (PAs). As compared with malignant indications, PD for benign or pre-malignant disease is often associated with increased morbidity. While the Spigelman classification assesses malignancy risk for familial adenomatous polyposis (FAP)-related duodenal adenomas, no malignancy risk score (MRS) exists for non-FAP related PAs.

Helicobacter pylori infection is associated with significant elevations to fecal calprotectin, systemic inflammatory markers.

Objectives: Fecal calprotectin (FC) is a marker commonly used in the diagnosis and follow-up of inflammatory bowel diseases (IBD). However, other gastrointestinal conditions, like H. pylori (HP) infection, can result in increased neutrophil activity as well.
