Background: Acoustic cavitation which occurs at high intensities of ultrasound waves can be fatal for tumor cells; however, it can be used to destroy cancer cells as an efficient therapeutic method. On the other hand, it is known that the existence of nanoparticles in a liquid decreases the acoustic cavitation onset threshold. Materials and Methods: In this work, the combined effects of therape...

Sinonasal teratocarcinosarcoma (STCS) is a rare, morphologically heterogeneous and highly aggressive tumour of ambiguous origin. It is characterized by the presence of benign and malignant epithelial, mesenchymal and neuroectodermal components. Because of their rarity and heterogeneity, these lesions are often misdiagnosed, leading to management difficulties. Adequate sampling with a high index...

Inflammatory myofibroblastic tumor is an uncommon benign neoplasm and its presentation in small bowel is rare. Due to clinical manifestation, laboratory data and radiologic results, there is an increased risk of over diagnosis as malignant tumors particularly malignant lymphoma in childhood therefore may be resulting in wrong therapeutic approach. However pathologic findings could be demonstrat...

In this paper, we propose and discuss four fitness features considered as essential for developing personal learning environments (PLE) that are viable and ready for appropriation.

Cystic lymphangioma is a rare benign tumour occurring during childhood. This tumour, caused by lymphatic system malformations, commonly occurs in head and neck regions. Herein, we report the case of a three-month-old male infant, diagnosed with a large cystic mass in the abdominal cavity and groin. The infant presented with low-grade fever and significant abdominal distension. Abdominal CT scan...

After speculation in the literature about the nature of Personal Learning Environments, research in the design and development of PLEs is now in progress. This paper will report on the first phase of research in a PLE, the identification process, of what potential users would find important components, applications and tools on a PLE. The methodology includes surveying “super-users” on their us...

An increasing body of evidence indicates that p53, the product of a tumour suppressor gene, has a role in development - could this developmental role have provided the primary driving force in the evolution of a protein best known as a stress-response integrator?

background: prognostic models have clinical appeal to aid therapeutic decision making. two main practical challenges in development of such models are assessment of validity of models and imputation of missing data. in this study, importance of imputation of missing data and application of bootstrap technique in development, simplification, and assessment of internal validity of a prognostic mo...
