background and aims. helicobacter pylori is a microaerophilic gram-negative spiral organism. it is recognized as the etiologic factor for peptic ulcers, gastric adenocarcinoma and gastric lymphoma. recently, it has been isolated from dental plaque and the dorsum of the tongue. this study was designed to assess the association between h. pylori and oral lesions such as ulcerative/inflammatory le...

PURPOSE To evaluate the diagnostic value of magnetic resonance diffusion-weighted imaging (DWI) using apparent diffusion coefficient (ADC) values to the characterization of breast lesions and differentiation of benign and malignant lesions. MATERIALS AND METHODS Thirty-seven women (mean age, 38 years) with 37 enrolled in the study. DWI and ADC maps in the axial plane were obtained using a 1.5...

The present study was designed to identify the effect of obesity for induction histological lesions liver and kidneys in female rats Rattus norvegicus. treated with herbal therapy (aqueous extract grape leaves) used 16 which distributed randomly into four groups (each group containing female) first control administrated only normal diet water, second fed a high fat three months without treatmen...

Introduction: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system (CNS), affecting mostly young people at a mean age of 30 years. Magnetic resonance imaging (MRI) is one of the most specific and sensitive methods in diagnosing and detecting the evolution of multiple sclerosis disease. But it does not have the ability to differentiate between distinct histopathologic...

Neuro-axonal degeneration occurs progressively from the onset of multiple sclerosis and is thought to be a significant cause of increasing clinical disability. Several histopathological studies of multiple sclerosis and experimental autoimmune encephalomyelitis have shown that the accumulation of sodium in axons can promote reverse action of the sodium/calcium exchanger that, in turn, leads to ...

multiple primary tumors in a single patient are relatively rare when four or more distinct lesions are considered. herein, we report a case of woman with four different primary tumors: meningioma, renal angiomyolipoma, spinal ependymoma and high-grade soft tissue sarcoma. there was no family history and hereditary syndrome. the genetic analysis was completely normal. to best of our knowledge, t...

background: the role of retinoblastoma (rb) protein in cell cycle regulation prompted us to take up this study with the aim of assessing its role in the progression of oral cancer and to correlate with various clinicopathological parameters, including habits such as smoking, paan chewing, and alcoholism. materials and methods: this observational study included surgical specimens from 10 apparen...

PURPOSE We aimed to determine the apparent diffusion coefficients (ADCs) of focal breast lesions on diffusion-weighted magnetic resonance imaging (DW-MRI) and to evaluate whether ADC measurement can be used to characterize lesions as benign or malignant. MATERIALS AND METHODS Fifty-one patients between the ages of 18-79 years (mean age, 48.5 years) with 51 histopathologically verified breast ...

Mimickers of soft tissue tumours in the hand and wrist are more frequent than true neoplastic lesions. Pseudotumours belong to a large and heterogeneous group of disorders, varying from normal anatomical variants, cystic lesions, post-traumatic lesions, skin lesions, inflammatory and infectious lesions, non-neoplastic vascular lesions, metabolic disorders (crystal deposition disease and amyloid...
