High-grade glioma (HGG), a deadly primary brain malignancy, manifests radioresistance mediated by cell-intrinsic and microenvironmental mechanisms. High levels of the cytokine transforming growth factor-β (TGF-β) in HGG promote enforcing an effective DNA damage response supporting stem cell self-renewal. Our analysis TCGA data immunohistochemical staining phosphorylated Smad2, which is main transducer canonical TGF-β signaling, indicated variable pathway activation across tumors. These...

Patients with multiple myeloma are immunosuppressed due to both the disease itself and immunosuppressive therapies. Thus, when presenting respiratory failure pulmonary opacities, pneumonia must be considered. However, while rare, immunomodulating medications used in treatment of can also cause potentially life-threatening failure, a distinction which has important implications.

INTRODUCTION: Gastric cancer is one of the most common cancers worldwide, but evidence for screening and surveillance in US limited by sparse clinical research. While recent immigrants from endemic regions such as East Asia are known to be at high risk, it’s unclear what important risk factors a population with fewer immigrants. Therefore, we conducted matched case-control study VA medical center. METHODS: We identified individuals gastric using both tumor registry electronic record New York...
