Development of an H&E on-block staining technique for collagen detection in cryo-fluorescence tomography imaging of frozen breast tissue samples.

Background: Hematoxylin and eosin (H&E) staining is widely considered to be the gold-standard diagnostic tool for histopathology evaluation. However, the fatty nature of some tissue types, such as breast tissue, presents challenges with cryo-sectioning, often resulting in artifacts that can make histopathologic interpretation and correlation with other imaging modalities virtually impossible. We present an optimized on-block H&E staining technique that improves contrast for identifying collagenous stroma during cryo-fluorescence tomography (CFT) sectioning.

Acute Myeloid Leukemia Skews Therapeutic WT1-specific CD8 TCR-T Cells Towards an NK-like Phenotype that Compromises Function and Persistence.

Acute myeloid leukemia (AML) that is relapsed and/or refractory post-allogeneic hematopoietic cell transplantation (HCT) is usually fatal. In a prior study, we demonstrated that AML relapse in high-risk patients was prevented by post-HCT immunotherapy with Epstein-Barr virus (EBV)-specific donor CD8 T cells engineered to express a high-affinity Wilms Tumor Antigen 1 (WT1)-specific T-cell receptor (TTCR- C4). However, in the present study, infusion of EBV- or Cytomegalovirus (CMV)-specific T did not clearly improve outcomes in fifteen patients with active disease post-HCT.

Stakeholder perspectives on facilitators and barriers to implementing a zero-dollar copay program for chronic conditions study.

Background: Type 2 diabetes mellitus (T2D) remains a pressing public health concern. Despite advancements in antidiabetic medications, suboptimal medication adherence persists among many individuals with T2D, often due to the high cost of medications. To combat this issue, Blue Cross and Blue Shield of Louisiana (Blue Cross) introduced the $0 Drug Copay (ZDC) program, providing $0 copays for select drugs.

Inter-city movement pattern of notifiable infectious diseases in China: a social network analysis.

Background: Co-existence of efficient transportation networks and geographic imbalance of medical resources greatly facilitated inter-city migration of patients of infectious diseases in China.

Methods: To characterize the migration patterns of major notifiable infectious diseases (NIDs) during 2016-2020 in China, we collected migratory cases, who had illness onset in one city but were diagnosed and reported in another, from the National Notifiable Infectious Disease Reporting System, and conducted a nationwide network analysis of migratory cases of major NIDs at the city (prefecture) level.

Findings: In total, 2,674,892 migratory cases of NIDs were reported in China during 2016-2020.

Study of the Pore Structure and Fractal Characteristics of the Leping Formation Shale in the Junlian Block, Southern Sichuan Basin.

The pore structure of shale is a key factor affecting the occurrence and flow of shale gas, and fractal dimensions can be used to quantitatively describe the complexity of the shale pore structure. In this study, the Leping Formation shale in the Junlian block of the southern Sichuan Basin was investigated. The pore structure characteristics of this shale were examined via low-pressure CO adsorption (LP-COA) and low-temperature N adsorption (LT-NA) methods via field emission scanning electron microscopy (FE-SEM), shale geochemistry, and mineral composition analysis.
