Tumor hypoxia promotes angiogenesis, dysfunctional vascular formation, and the epithelial-to-mesenchymal transition phenotype. We propose that a CXCR4 inhibitor (AMD3100) could decrease cancer stemness and improve the efficacy of the anticancer drug gemcitabine (GEM) in targeting hypoxic pancreatic ductal adenocarcinoma (PDAC) cells. In this study, we synthesized a hypoxia-responsive polymer containing poly(lactic acid)-diazobenzene-poly(ethylene glycol) to produce hypoxia-responsive...

Wound healing after myocardial infarction (MI) is a dynamic and multifaceted process that links the molecular alterations induced by or in response to prolonged ischemia with structural and physiological changes to the damaged myocardium. Changes, at the tissue level, are driven by a complex intersection of cellular and molecular mechanisms that operate along a classic wound healing paradigm as an attempt to repair the damaged myocardium and restore cardiac physiology. Maladaptive healing...

BACKGROUND: Mycoplasma pneumoniae is a known causative agent for community-acquired pneumonia. Extrapulmonary manifestations can occur independently of pneumonia in Mpneumoniae infection, and cardiac involvement is around 1% to 5%. Myocarditis and pericarditis are often associated with mycoplasma infections.
