Renal cell carcinoma (RCC) metastasis to duodenum is very rare and only a few case reports are available in the literature. We here reported a patient with solitary duodenal metastasis presented with melena six years after right nephrectomy. The patient underwent upper gastrointestinal endoscopy showing ulcerative mass at the second portion of duodenum and biopsy of this mass was consistent wit...

OBJECTIVE To compare the diagnostic accuracy of intravoxel incoherent motion (IVIM)-derived parameters and apparent diffusion coefficient (ADC) in distinguishing between renal cell carcinoma (RCC) and fat poor angiomyolipoma (AML). MATERIALS AND METHODS Eighty-three patients with pathologically confirmed renal tumors were included in the study. All patients underwent renal 1.5T MRI, including...

The main objective of this study was to assess cardiac death (CD) kidney grafts before transplantation to determine whether blood oxygen level-dependent (BOLD) and diffusion MRI techniques can predict damage to these grafts after transplantation. We assessed CD kidney tissue by BOLD and diffusion MRI. We also examined pathological and gene expression changes in CD kidney grafts before and after...

BACKGROUND Chemical-shift magnetic resonance imaging (MRI) has been known to successfully differentiate adenomas from metastases. However, there has been concern that metastasis from extra-adrenal primary malignancies which contain high lipid content such as clear cell renal cell carcinoma (RCC) could mimic adrenal adenomas. PURPOSE To evaluate the ability of MR to differentiate adrenal adeno...

Objectives: The purpose the study was to evaluate role of diffusion weighted magnetic resonance imaging (DW-MRI) in diagnosis benign and malignant breast lesions, calculate a cut-off apparent coefficient (ADC) value explore use relative ADC (r ADC) for improving sensitivity specificity MRI cancer. Methods: This retrospective based on cohort patients who underwent dynamic contrast enhanced (DCE)...

Microphthalmia-associated transcription (MiT) family translocation renal cell carcinoma (tRCC) comprises Xp11 tRCC and t(6;11) RCC. Due to the presence of fusion genes, Xp11 tRCC and t(6;11) RCC are also known as TFE3- and TFEB-rearranged RCC, respectively. TFE3 and TFEB belong to the MiT family, which regulates melanocyte and osteoclast differentiation, and TFE3- and TFEB-rearranged RCC show c...

OBJECTIVE We aimed to describe the efficacy and safety of sunitinib in unselected Korean advanced renal cell carcinoma (RCC) patients. PATIENTS AND METHODS From November 2005 to August 2008, 132 histologically confirmed advanced RCC patients (100 in the global expanded access program) were enrolled. Response and toxicity were assessed regularly according to the protocol. RESULTS Within this...

INTRODUCTION The effect of emergency department (ED) crowding has been recognized as a concern for more than 20 years; its effect on productivity, medical errors, and patient satisfaction has been studied extensively. Little research has reviewed the effect of ED crowding on medical education. Prior studies that have considered this effect have shown no correlation between ED crowding and resid...

The purpose of this study was to investigate the reliability of the Royal London Space Analysis (RLSA) and to evaluate its influence on orthodontic treatment decisions. Thirty-one case records were collected to represent various levels of crowding and different types of malocclusions. Seventeen examiners assessed these records and completed a data sheet that recorded information on their treatm...

We present a general-purpose model for biomolecular simulations at the molecular level that incorporates stochasticity, spatial dependence, and volume exclusion, using diffusing and reacting particles with physical dimensions. To validate the model, we first established the formal relationship between the microscopic model parameters (timestep, move length, and reaction probabilities) and the m...
