Identification and gene expression profiling of human gonadotrophic pituitary adenoma stem cells
Acta Neuropathologica Communications, 2023 Background Gonadotrophic pituitary adenoma is a major subtype of pituitary adenoma in the sellar region, but it is rarely involved in the hypersecretion of hormones into blood; thus, it is commonly regarded as “non-functioning.” Its tumorigenic ...

Preoperative Volume Determination for Pituitary Adenoma [PDF]
, 2016 The most common sellar lesion is the pituitary adenoma, and sellar tumors are approximately 10-15% of all intracranial neoplasms. Manual slice-by-slice segmentation takes quite some time that can be reduced by using the appropriate algorithms. In this contribution, we present a segmentation method for pituitary adenoma.

Improving Precancerous Case Characterization via Transformer-based Ensemble Learning [PDF]
arXiv, 2022 The application of natural language processing (NLP) to cancer pathology reports has been focused on detecting cancer cases, largely ignoring precancerous cases. Improving the characterization of precancerous adenomas assists in developing diagnostic tests for early cancer detection and prevention, especially for colorectal cancer (CRC).

Acta Neuropathologica Communications, 2015 The term atypical pituitary adenoma (APA) was revised in the 2004 World Health Organization (WHO) classification of pituitary tumors. However, two of the four parameters required for the diagnosis of APAs were formulated rather vaguely (i.e., “extensive”

Effects of loperamide on the human hypothalamo-pituitary-adrenal axis in vivo and in vitro. [PDF]
, 1992 Loperamide, an opiate agonist of high specificity for p-receptors, was recently reported to suppress ACTH and cortisol levels in normal subjects, but not in patients with proven ACTH-dependent Cushing’s disease. However, there is little information on

Preservation of multidimensional quality of life after endoscopic pituitary adenoma resection.
Journal of Neurosurgery, 2015 OBJECT Pituitary adenomas are well suited to resection by a minimal-access endoscopic technique. Validation of this approach requires prospective outcome studies to determine the impact on quality of life (QOL).
