The effects of diet on the composition and properties of adipose tissue in relation to lymph nodes were studied in adult guinea-pigs. The proportions of monoenoic triacylglycerol fatty acids were constant in all sites in adipose tissue of similarly fed guinea-pigs, but were substantially greater in samples from guinea-pigs fed on suet-enriched chow. Triacylglycerols in adipose tissue from near ...

We describe the case of a 36-years-old male patient, originating from India, who presented with enlarged cervical lymph nodes and elevated liver chemistry tests. Histologically necrosing granulomas were observed in the lymph nodes, and PCR revealed DNA from mycobacterium tuberculosis. However, in the liver biopsy granulomatous hepatitis without central necrosis was seen. With a positive PCR for...

background while tuberculosis (tb) can be diagnosed by microscopy and culture, the sensitivity of ziehl-neelsen staining is variable and culture results require 4 - 8 weeks to be determined. polymerase chain reaction (pcr) and its modifications, including nested pcr, might be promising methods for the rapid diagnosis of tb. objectives this study aimed to evaluate the performance of nested pcr o...

INTRODUCTION Acute pancreatitis is a local inflammatory process that leads to a systemic inflammatory response in the majority of cases. Bacterial contamination has been estimated to occur in 30-40% of patients with necrotizing pancreatitis. Development of pancreatic necrosis depends mainly on the degree of inflammation and on the microvascular circulation of the pancreatic tissue. Activated pr...

OBJECTIVE To investigate the relation of Fas and Fas ligand (FasL) protein expression with carcinogenesis and metastasis of cardiac carcinoma. METHODS Immunohistochemistry was used to detect Fas and FasL protein expression in 64 cardiac carcinoma tissue samples and 20 normal gastric tissue samples. Relation between FasL and Fas expression, age and gender of gastric cancer patients, and pathol...

Lymphatic vasculature in solid tumors may serve as the pathway for metastatic spread of the cancer to the regional lymph nodes and to distant organs. Controversy still exists whether tumors metastasize through existing lymphatics or through newly formed vessels (lymphangiogenesis). The role of lymphangiogenesis in lymphoma spread and proliferation is not clearly established. VEGF-C is the most ...

we report a case of a 75-year old man that came at hematologist’s attention for lymphoma evaluation due to axillary lymph node enlargement and fever. thorax, abdomen and pelvis contrast-enhanced computed tomography (cect) showed lymph nodes, spleen and liver lesions. axillary lymph node biopsy was performed and the diagnosis of marginal zone lymphoma (mzl) at stage iv was postulated, then the p...

Cat scratch disease (CSD), the typical clinical manifestation of Bartonella infections usually follows a typical benign self-limited course. Nevertheless, a variety of unusual clinical manifestations and confusing imaging features can lead to misinterpretations and render the disease a diagnostic dispute. Routine laboratory tests exhibit varying reported sensitivity and are usually unhelpful in...
