1. Expression of estrogen and progesterone receptors in astrocytomas: a literature review
Gliomas are the most common type of primary central nervous system neoplasm. Astrocytomas are the most prevalent type of glioma and these tumors may be influenced by sex steroid hormones. A literature review for the presence of estrogen and progesterone receptors in astrocytomas was conducted in the PubMed database using the following MeSH terms: “estrogen

2. Segmentação de tumores de encéfalo em imagens por ressonância magnética baseada em informações texturais. / Brain tumor segmentation in magnetic resonance images based on texture information.
Magnetic resonance images are essential in the diagnosing and treatment of brain tumors due to its high amount of anatomic details. The task of segmenting brain tumor regions in these images makes more exact quantitative analysis feasible, allowing a better tracking of the evolution/regression of the disease. Nevertheless, the execution of such task is burde

5. Central nervous system involvement in Hodgkin's lymphoma associated with Epstein-Barr virus in a patient with AIDS: case report and review of the literature
Intracranial and intraspinal involvement is a rare complication of Hodgkin's disease. We report a case of a patient with diagnosis of AIDS and Hodgkin's lymphoma who developed brain and spinal involvement at the time of the relapse of the neoplasm disease. Mixed cellularity histology was the subtype of Hodgkin's disease in our patient; we identified the Epst

6. Stereotactic radiosurgery in the treatment of brain metastases: efficacy and complications based on brain location / Radiocirurgia no tratamento das metástases cerebrais: resposta terapêutica e complicações baseadas na localização da lesão
Brain metastases are the most common Central Nervous System tumors. Among the therapy options stereotactic radiosurgery has became in the last two decades an usefulness treatment technique attending with lower complication and mortality rate. However, even an extended literature review, many questions remain unclear about this therapy modality, mainly relate

7. Avaliação clínica da saúde bucal de crianças com neoplasias malignas atendidas no Hospital Infantil Varela Santiago em Natal-RN
The childhood cancer is characterized by a predominance of hematogenic and lymphatic system neoplasm, although a fTequency of the central nervous system tumors and sarcomas are widely common. Particularities of many childhood cancers and the adverses effect of the antineoplastic agents can change radically the oral environrnent and predisposes to the risk of

8. Serum leucine-enkephalin in bronchial carcinoma and its relation to tumour location.
Serum concentrations of the opioid peptide leucine-enkephalin were measured by radioimmunoassay in 30 patients with histologically confirmed bronchial carcinoma and 10 control subjects. This peptide, which is present in greatest amounts in the central and autonomic nervous systems, has previously been found in bronchial neoplasms. The mean serum concentratio

9. Current and Future Gene Therapy for Malignant Gliomas
Malignant gliomas are the most common neoplasm in the central nervous system. When treated with conventional treatments including surgery, irradiation, and chemotherapy, the average life expectancy of the most malignant type, glioblastoma multiforme is usually less than 1 year. Therefore, gene therapy is expected to be an effective and possibly curative trea

10. Study of disease associations from linked records.
Comparisons are made between the principal diagnosis on discharge from hospital in successive periods of inpatient care for persons in the Oxford Record Linkage Study area admitted over a period of years. The observed numbers of pairs of diagnoses are compared with expected numbers computed to take account of the discharge rates in the population by age and

11. Conservation of the Drosophila lateral inhibition pathway in human lung cancer: A hairy-related protein (HES-1) directly represses achaete-scute homolog-1 expression
The achaete-scute genes encode essential transcription factors in normal Drosophila and vertebrate nervous system development. Human achaete-scute homolog-1 (hASH1) is constitutively expressed in a human lung cancer with neuroendocrine (NE) features, small cell lung cancer (SCLC), and is essential for development of the normal pulmonary NE cells that most re

12. Ectopic intracranial retinoblastoma in childhood.
Twelve out of a series of 630 children with retinoblastoma, treated in the ocular oncology units at St Bartholomew's and Moorfields Eye Hospitals during the past 30 years, have developed ectopic intracranial retinoblastoma. The ectopic tumour occurred in the pineal region in eight children and in the suprasellar region in four. Ten patients had bilateral ret
