A self-expanding coated stent was eventually placed to seal the esophageal perforation with significant improvement in the clinical condition of the patient. At 1-year follow-up, the patient is tolerating an oral diet with no(More)
The role of inositol polyphosphates (InsPs) in the mediation of cellular apoptosis was investigated in mouse MC3T3 osteoblastic cell line. Extracellular administration of InsP4, InsP5, and InsP6 increased apoptosis in a dose-dependent manner. InsP6 was more potent than InsP5 and InsP4 in promoting apoptosis. Inositol hexasulfate (InsS6), a structural analog(More)
Our patient, a resident of Arkansas, presented with a solitary pulmonary nodule for lung resection to rule out primary lung cancer. However, pathologic examination showed the lung nodule to be a granuloma secondary to dirofilariasis. Human pulmonary dirofilariasis is a rare zoonotic disease caused by Dirofilariasis immitis (dog heartworm) that is usually(More)
Classical MHC class I glycoproteins (HLA-A, B, and C) present endogenous cytosolic peptide antigen fragments to CD8-positive T-cells. CD8-positive T-cell recognition and destruction of virus-infected cells are dependent on adequate cellular MHC class I expression. Constitutive MHC class I expression is ubiquitous, but known to be deficient on specific(More)
