Enhanced nestin expression and small blood vessels in human pituitary adenomas
(Springer, 2013-09)
The role of angiogenesis in human pituitary tumor progression is questioned. Our aim was to characterize the morphologic changes that occur in the vasculature of pituitary adenomas, in correlation with the expression of ...
Immunohistochemistry for pituitary hormones and Ki-67 in growth hormone producing pituitary adenomas Evaluación por inmunohistoquímica de la expresión de hormonas hipofisiarias y del marcador de proliferación celular Ki-67 en tejido de adenomas causantes
(2008)
Background: Growth hormone (GH) producing adenomas, frequently express several hormones. This condition could confer them a higher proliferative capacity. Ki-67 is a nuclear protein antigen that is a marker for proliferative ...
Pathogenesis of pituitary adenomas [Patogénesis de los adenomas hipofisiarios]
(2011)
In the present study, we report the isolation and characterization of seabream Sparus aurata pyloric caeca-duodenal lipase. Optimum activity was found at pH 8.5 and salinity of 50 mM NaCl. Lipase activity was sensitive to ...
Predictive factors for the development of visual loss in patients with pituitary macroadenomas and for visual recovery after optic pathway decompression
(CANADIAN OPHTHAL SOC, 2010)
Objective: To investigate clinical and MRI findings that are predictive of both visual loss in patients with pituitary adenomas and visual recovery after treatment. Design: Cohort study. Participants: Thirty patients (60 ...
Granular Cell Tumor (gct) Mimicking A Nonsecreting Anterior Pituitary Adenoma [tumor De Células Granulares (tcg) Mimetizando Um Adenoma Hipofisário Não Produtor]
(Associacao Arquivos de Neuro-Psiquiatria, 2015)
Aspectos moleculares da tumorigênese hipofisária
(Sociedade Brasileira de Endocrinologia e Metabologia, 2008)
Os tumores hipofisários, adenomas em sua quase totalidade, são de ocorrência freqüente, representando 10% a 15% de todas as neoplasias intracranianas. Estas lesões são classificadas em microadenomas (< 10 mm) ou macroadenomas ...
Association of PTP4A3 expression and tumour size in functioning pituitary adenoma: A descriptive study
(B M J Publishing Group, 2021-03)
PTP4A3 is a subclass of a protein tyrosine phosphatase super family and is expressed in a range of epithelial neoplasms. We evaluated PTP4A3 expression and its association with clinical-pathological parameters in different ...
Intrasellar pressure and tumor volume in pituitary tumor: relation study
(Academia Brasileira de Neurologia - ABNEURO, 2006-12-01)
OBJECTIVE: To determine if there was a relationship between intrassellar pressure (ISP) and pituitary tumor volume. METHOD: Between August 2002 and May 2004, 60 patients aged between 13 and 75 years old (39 males), having ...
Adenomas hipofisários produtores de ACTH: Aspectos neurocirúrgicos
(Academia Brasileira de Neurologia - ABNEURO, 2002-03-01)
We report our experience with 19 cases of ACTH secreting pituitary adenomas. They were microadenomas in 50% of the cases, coming with the typical picture of the Cushing syndrome. The ACTH adenoma associated with other types ...
