BACKGROUND The migration and proliferation of myofibroblasts are prominent features of myointimal hyperplasia associated with haemodialysis polytetrafluoroethylene (PTFE) grafts. Since C-reactive protein (CRP) possesses functional activities on vascular smooth muscle cells (SMCs), we examined the expression of this protein in PTFE grafts early in the course of myointimal hyperplasia development...

Red meat consumption is associated with an increased colon cancer risk. Heme, present in red meat, injures the colon surface epithelium by luminal cytotoxicity and reactive oxygen species. This surface injury is overcompensated by hyperproliferation and hyperplasia of crypt cells. Transcriptome analysis of mucosa of heme-fed mice showed, besides stress- and proliferation-related genes, many upr...

Increased numbers of bone marrow megakaryocytes and thrombocytosis are frequently observed in patients with myeloproliferative disorders (MPD). Increased marrow megakaryocytes and thrombocytosis are also noted in a variety of inflammatory and neoplastic disease leading to the phenomenon of reactive thrombocytosis (RT). The pathogenesis of this finding remains incompletely understood. Using meth...

Inflammatory responses appear to play an important role in the occurrence of restenosis following coronary intervention. However, the contribution of C-reactive protein (CRP) and oxidative stress to restenosis after balloon angioplasty and stent implantation remains unclear. The aim of this study was to examine this issue using hyperlipidemic rabbits. Rabbits were divided into two groups; they ...

primary cutaneous anaplastic large cell lymphoma is a t-cell malignancy with atypical cd30 positive lymphocytes. pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

INTRODUCTION Intravascular lesions of the hand comprise reactive and neoplastic entities. The clinical diagnosis of such lesions is often difficult, and usually requires pathologic examination. We present the largest series to date of intravascular lesions affecting the hand. METHODS A retrospective review of intravascular (arterial and venous) lesions involving the hand was conducted. Data r...
