AIMS To assess which pathological features are associated with a sensitive marker of liver fibrogenesis and thus of the potential development of fibrosis in hepatitis C. METHODS The degree of liver fibrogenesis was evaluated by quantification of type I collagen mRNA and transforming growth factor (TGF) beta 1 mRNA (a major profibrogenic cytokine) in liver biopsy specimens from 28 patients wit...

Introduction: There are several different molecular pathways in tissue damage by Ischemic Brain Injury. The use of antioxidants and free radical scavengers are a matter of attention by some researchers. Crocus sativus (saffron) is used previously for protective effects in ischemia state by some researchers. To assess pathologic aspects of neuroprotection of saffron in some susceptible brain are...

Extramammary Paget's disease (EMPD) is a distinct form of malignant skin neoplasm. The clinicopathological significance of cutaneous adnexal involvement in EMPD has not been investigated in detail. Surgical specimens were obtained from 53 patients with primary EMPD. Tumor involvement of cutaneous adnexal structures was evaluated using histological parameters. The degree of involvement was score...

PURPOSE In the field of cancer research, there has been a paucity of interest in necrosis, whereas studies focusing on apoptosis abound. In neuro-oncology, this is particularly surprising because of the importance of necrosis as a hallmark of glioblastoma (GBM), the most malignant and most common primary brain tumor, and the fact that the degree of necrosis has been shown to be inversely relate...

AIM To examine the usefulness of the histopathological finding of tumor necrosis for stratifying TNM stage IV colorectal cancer in R0 status. PATIENTS AND METHODS We enrolled 98 patients with stage IV colorectal cancer, without residual disease after resection. The extent of necrosis was assessed using published thresholds, the extent was graded as "absent", "moderate" (<30% of tumor area), o...

Bone tissues from a variety of different skeletal elements of 89 healthy rhesus monkeys in an age series xwere screened for nonpathologic osteocy te necrosis.* Incidence of cellular necrosis x as found directly related to the age of the monkey. Virtually no cellular necrosis was found in very young monkeys having primary dentition. Bone samples from about half of the monkeys with mixed (lentiti...

warfarin induced skin necrosis is a rare complication associated with the use of oral ‎anticoagulants. most patients develop this complication at the initiation of therapy. the complication is ‎usually associated with an underlying thrombophilia. here we describe a case of a 75 year old ‎patient who developed skin necrosis in her both breasts during warfarin treatment for a ‎deep vein thrombosi...
