A majority of families with hereditary nonpolyposis colorectal cancer (HNPCC) are attributable to germline mutations in three DNA mismatch repair (MMR) genes, MLH1, MSH2 and MSH6. However, the clinical phenotype appears to reflect a complex interplay between the predisposing mutation and putative constitutional and somatic modifiers. Certain MMR gene mutations predispose to combined occurrence ...
this study was undertaken to examine the ability of spect in differentiation of a pulmonary lesion suspecions of lung cancr. a total of 170 patients with suspected lung cancer were studied. a dose of tl-201 chloride {148-296 mbq) was injected intravenously and tomographic early and delayed scans were obtained at 15 miniutes and 3 hours post injection, respectively. delayed tl-201 spect visulize...

BACKGROUND Boron neutron capture therapy (BNCT) is a cell-selective radiation therapy that uses the alpha particles and lithium nuclei produced by the boron neutron capture reaction. BNCT is a relatively safe tool for treating multiple or diffuse malignant tumors with little injury to normal tissue. The success or failure of BNCT depends upon the 10B compound accumulation within tumor cells and...
We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of unifor...
Epidemiological studies provide strong evidence that obesity and the associated adipose tissue inflammation are risk factors for breast cancer; however, the molecular mechanisms are poorly understood. We evaluated the effect of a high-fat/high-calorie diet on mammary carcinogenesis in the immunocompetent MMTV-PyMT murine model. Four-week old female mice (20/group) were randomized to receive eit...
Visceral urate deposition (visceral gout) is a common finding during post-mortem examination of poultry. Rare cases of visceral gout may occur in wild birds. A rare case of visceral urate deposition in a little bittern (Ixobrychus minutus) is reported here. In May 2013, carcass of a little bittern was submitted for necropsy to the Clinic of Poultry Diseases (Faculty of Veterinary Medic...
Five cases of visceral leishmaniasis are reported. The youngest patient was one year old and the eldest 8 years. All belonged to low-income families and their growth and development caracteristics were below standard. Diagnosis was confirmed in 4 cases through bone marrow aspiration and in one case by raised serum antibody titer prior to treatment and dramatic response to specific treatment. He...
Injection of strain MC29 avian leukosis virus into the peritoneal, pericardia!, and air sac cavities of the chicken resulted in high incidence of tumors of the mesothelium of the respective structures. As determined by light and electron microscopy, the growths arose as papillomas or expanding tumors by alteration of the squamous mesothe lium to spheroidal or cuboidal cells characterized by rou...
