Cardiovascular Disease and Breast Cancer Stage at Diagnosis.
JAMA Netw Open
January 2025
Department of Epidemiology, University of Texas MD Anderson Cancer Center, Houston.
Importance: Cardiovascular disease (CVD) and cancer are the leading causes of mortality in the US. Large-scale population-based and mechanistic studies support a direct effect of CVD on accelerated tumor growth and spread, specifically in breast cancer.
Objective: To assess whether individuals presenting with advanced breast cancers are more likely to have prevalent CVD compared with those with early-stage breast cancers at the time of diagnosis.
Dynamic Features Driven by Stochastic Collisions in a Nanopore for Precise Single-Molecule Identification.

Nanopore technology holds great potential for single-molecule identification. However, extracting meaningful features from ionic current signals and understanding the molecular mechanisms underlying the specific features remain unresolved. In this study, we uncovered a distinctive ionic current pattern in a K238Q aerolysin nanopore, characterized by transient spikes superimposed on two stable transition states.

In confronting the significant challenge posed by multidrug-resistant (MDR) pathogens, particularly methicillin-resistant (MRSA), the development of innovative anti-infective strategies is essential. Our research focuses on sortase A (SrtA), a vital enzyme for anchoring surface proteins in . We discovered that plantamajoside (PMS), a phenylpropanoid glycoside extracted from .

Tumor cell-intrinsic signaling pathways can drastically affect the tumor immune microenvironment, promoting tumor progression and resistance to immunotherapy by excluding immune-cell populations from the tumor. Several tumor cell-intrinsic pathways have been reported to modulate myeloid-cell and T-cell infiltration creating "cold" tumors. However, clinical evidence suggests that excluding cytotoxic T cells from the tumor core also mediates immune evasion.

Unlabelled: Ubiquitous in nature, biofilms provide stability in a fluctuating environment and provide protection from stressors. Biofilms formed in industrial processes are exceedingly problematic and costly. While biofilms of sulfate-reducing bacteria in the environment are often beneficial because of their capacity to remove toxic metals from water, in industrial pipelines, these biofilms cause a major economic impact due to their involvement in metal and concrete corrosion.
