BACKGROUND Elevated Cyclooxygenase-2 (COX-2) expression is thought to increase metastatic potential of many tumors. Furthermore, elevated COX-2 expression correlates with radiation resistance in many tumor types. We evaluated whether: (i) the degree of COX-2 expression correlated with either metastatic tumor type or with the presence of necrosis and whether (ii) radiation-resistant tumors (rena...

PURPOSE To describe the MR features of primary central nervous system (CNS) lymphoma and to determine whether there is a correlation with histopathologic findings. METHODS The MR images, pathologic specimens, and clinical records of 23 patients with primary CNS lymphoma were reviewed. The imaging and pathologic characteristics were tabulated and compared by using the standard tests for associ...

OBJECTIVES The purpose of our study is to investigate whether diffusion-weighted imaging (DWI) is useful for monitoring the therapeutic response after neoadjuvant chemotherapy in osteosarcoma of long bones. MATERIALS AND METHODS Conventional magnetic resonance imaging (MRI) and DWI were obtained from 35 patients with histologically proven osteosarcomas. MR examinations were performed in all p...

purpose: to report a case of acute retinal necrosis following herpetic encephalitis. case report: a 25-year-old male presented with pain and visual loss in his left eye. he had herpetic encephalitis 1 month prior to the visual symptoms. ophthalmologic examination and paraclinical evaluation disclosed acute retinal necrosis. conclusion: herpetic encephalitis may be a risk factor for acute retina...

discussion transthoracic echocardiography disclosed massive pericardial effusion, respiratory variation in mitral and tricuspid inflow e velocity, increased diastolic flow reversal with expiration in the hepatic vein, septum deviation in inspiration toward the left ventricle (lv), preserved lv function, and inferior vena caval (ivc) dilation without any collapse in inspiration. chest computed t...

abstract background: the varieties of treatment methods for the scaphoid non:::::union::::: have always been a discussable issue for orthopaedic surgeons. the current study, considered to be review for treatment results of the patients who sustained the scaphoid non:::::union::::: with or without avascular necrosis and compared these two groups clinically and radiologically. methods: the clinic...

This study examined the effect of long-term control of hyperglycemia with a new sodium glucose cotransporter 2 inhibitor, luseogliflozin, given alone or in combination with lisinopril on the progression of renal injury in the T2DN rat model of type 2 diabetic nephropathy. Chronic treatment with luseogliflozin (10 mg/kg/day) produced a sustained increase in glucose excretion and normalized blood...

INTRODUCTION The aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (MTA) and 0.2% chlorhexidine (CHX) mixture to pure MTA, as a pulp capping material. METHODS AND MATERIALS The pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with MTA or MTA+0.2% CHX. After 2 months the animals were sacrificed and the teeth were pre...
