Myocardial infarction after coronary artery bypass graft (CABG) surgery has been described clinically in up to 30% of patients but there is little morphologic information about the character and pathogenesis of the myocardial injury. We studied myocardium in the distribution of bypassed and nonbypassed coronary arteries for the presence of contraction band necrosis as compared to coagulation ne...

background: hepatitis activity index (hai) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis b. the aim of this study was to determine the hai and fibrosing stage in patients with anti-hbe positive chronic hepatitis b. methods: liver biopsy slides of 72 patients were evaluated at the department of pathology in two teaching h...

conclusions the current study adds evidence to the association of tnf-α gene polymorphism and ms in this southern south iranian population which is consistent with the genetic analysis of ms in europeans (games) project reports and these two alleles reported in this study may be one of the genetic risk factor for ms. furthermore, this data can be used to build the iranian gene bank for future s...

background tnf-α is one of the most potent cytokines in proinflammatory reactions. results one hundred and twenty children with acute pyelonephritis were evaluated. urinary tnf-α/cr was 0.0051 ± 0.00083 pg/g creatinine. the authors found out a significant difference in urinary tnf-α/cr between patients who have normal and abnormal levels of urine leukocytes, urine protein, urine culture, erythr...

injection of synthetic fillers for soft tissue augmentation is increasing over the last decade. one of the most common materials used is hyaluronic acid (ha) that is safe and temporary filler for soft tissue augmentation. we present a case of 54-year-old female who experienced vascular occlusion and nasal alar necrosis following ha injection to the nasolabial folds. she suffered from pain, necr...

fat necrosis is a benign inflammatory process which can involve adipose tissue anywhere in the body. a previous history of trauma or surgery may or may not be present. information about the clinical and radiological appearance of this lesion is very important because it can mimic breast cancer. in this article, we review the features of fat necrosis in different imaging modalities including mam...

OBJECTIVE To assess the relationship between apparent diffusion coefficient (ADC) values on diffusion-weighted magnetic resonance (MR) imaging and pathologic measures of a tumor using a prostate cancer xenograft model. MATERIALS AND METHODS Eighteen athymic nude mice with 36 PC-3-induced tumors were sacrificed to obtain specimens immediately after MR imaging in order to compare the findings o...

abstract fat necrosis secondary to pancreatitis can be either mild and self limited or create severe organ damage, but may rarely lead to abdominal opancreatic pseudotumor. we report a case of fat necrosis secondary to pancreatitis which clinically simulates transverse colon cancer.

conclusions in our study, no prominent effect was seen; therefore, in order to have a better perspective of crocin activity against cancerous cell lines, further studies are highly recommended. results the highest concentration of crocin significantly decreased ros production after 48 hours of treatment. however, crocin had no effect on the expression level of hsp (heat shock protein). addition...
