The role of metal ions in Alzheimer's disease etiology is unresolved. For the redox-active iron and copper, formation reactive oxygen species by amyloid complexes has been proposed to contribute neurodegeneration. are generated copper redox cycling between its 1+ 2+ oxidation states. Thus, AβCuI complex potentially a critical reactant associated with etiology. Through competitive chelation, we have measured affinity soluble copper-binding domain amyloid-β peptide for CuI. dissociation...

Clinical trials and compassionate use agreements provide selected patients with access to potentially life-saving treatments before approval by the Food Drug Administration (FDA). Approval from FDA decreases a number of barriers; however, it is unknown whether associated increases in equitable novel therapies reductions disparities among cancer US.

Abstract Background Palliative treatment has been associated with improved quality of life and survival for a wide variety metastatic cancers. However, it is unclear whether the benefits palliative are uniformly experienced across US cancer population. We evaluated patterns outcomes based on socioeconomic, sociodemographic treating facility characteristics. Methods Patients diagnosed between 2008 2019 Stage IV primary nine organ sites were analyzed in National Cancer Database. The...

Pancreatitis is an inflammatory disease of the exocrine pancreas and ranks among most common gastrointestinal disorders. Inflamed tissues frequently experience conditions insufficient oxygen availability, or hypoxia. Here, we demonstrate that hypoxia consequent stabilization hypoxia-inducible factor 1α (HIF1α) transcription occur in murine human pancreatitis. Mice lacking pancreas-specific HIF1α expression display markedly impaired pancreatic regeneration following cerulein-induced...

Donation after cardiac death (DCD) liver transplantation is associated with increased biliary complications and graft failure. Yet for unclear reasons, DCD recipients relisted have lower wait-list mortality than other retransplant candidates. We used Organ Procurement Transplantation Network United Sharing data from 2002 to 2011 evaluate all the impact of utilization Model End-Stage Liver Disease (MELD) exception points on outcomes. Of 262 >2 weeks initial transplantation, 82 (31.3%) applied...

<h3>Importance</h3> The 2017 international PACIFIC trial established a role for immunotherapy after chemoradiation unresectable stage III non–small cell lung cancer (NSCLC). However, in the US, patients with NSCLC commonly differ from clinical populations terms of age, health, access to care, and treatment course, which may all factor into efficacy immunotherapy. <h3>Objective</h3> To determine outcomes use general US population. <h3>Design, Setting, Participants</h3> This cohort study...
