Classification of neuroendocrine neoplasms: lights and shadows
Reviews in Endocrine & Metabolic Disorders, 2020 Neuroendocrine neoplasms (NENs) are a heterogeneous group of neoplastic proliferations showing different morphological features, immunophenotype, molecular background, clinical presentation, and outcome. They can virtually originate in every organ of the

Pituitary Adenoma Segmentation [PDF]
arXiv, 2011 Sellar tumors are approximately 10-15% among all intracranial neoplasms. The most common sellar lesion is the pituitary adenoma. Manual segmentation is a time-consuming process that can be shortened by using adequate algorithms. In this contribution, we present a segmentation method for pituitary adenoma.

Deprenyl, an old drug with new anticancer potential: Mini review [PDF]
arXiv, 2021 The anticancer potential of monoamine oxidase (MAO) was observed in pre-clinical assays conducted with cell cultures and animals. L-Deprenyl (DEP) causes apoptosis in melanoma, leukemia and mammary cells. High-dose DEP has shown toxicity in mammary and pituitary cancers, as well as in monoblastic leukemia, in rats.

Non-functioning pituitary adenomas: indications for pituitary surgery and post-surgical management
Pituitary, 2019 PurposeNon-functioning pituitary adenomas (NFPAs) are associated with impaired well-being, increased comorbidities, and reduced long-term survival. Data on optimal management of NFPAs around surgical treatment are scarce, and postoperative treatment and ...

Transcriptome and methylome analysis reveals three cellular origins of pituitary tumors
Scientific Reports, 2020 Pituitary adenomas (PA) are the second most common intracranial tumors. These neoplasms are classified according to the hormone they produce. The majority of PA occur sporadically, and their molecular pathogenesis is incompletely understood.

NeoUNet: Towards accurate colon polyp segmentation and neoplasm detection [PDF]
arXiv, 2021 Automatic polyp segmentation has proven to be immensely helpful for endoscopy procedures, reducing the missing rate of adenoma detection for endoscopists while increasing efficiency. However, classifying a polyp as being neoplasm or not and segmenting it at the pixel level is still a challenging task for doctors to perform in a limited time.

Higher order organizational features can distinguish protein interaction networks of disease classes: a case study of neoplasms and neurological diseases [PDF]
arXiv, 2022 Neoplasms (NPs) and neurological diseases and disorders (NDDs) are amongst the major classes of diseases underlying deaths of a disproportionate number of people worldwide. To determine if there exist some distinctive features in the local wiring patterns of protein interactions emerging at the onset of a disease belonging to either of these two ...

Endocrine-Related Cancer, 2017 The classification of neoplasms of adenohypophysial cells is misleading because of the simplistic distinction between adenoma and carcinoma, based solely on metastatic spread and the poor reproducibility and predictive value of the definition of atypical

Stability and Hopf bifurcation analysis for the hypothalamic-pituitary-adrenal axis model with memory [PDF]
, 2016 This paper generalizes the existing minimal model of the hypothalamic-pituitary-adrenal (HPA) axis in a realistic way, by including memory terms: distributed time delays, on one hand and fractional-order derivatives, on the other hand. The existence of a unique equilibrium point of the mathematical models is proved and a local stability analysis is ...
