Brain tumor multi classification and segmentation in MRI images using deep learning [PDF]
arXiv, 2023 This study proposes a deep learning model for the classification and segmentation of brain tumors from magnetic resonance imaging (MRI) scans. The classification model is based on the EfficientNetB1 architecture and is trained to classify images into four classes: meningioma, glioma, pituitary adenoma, and no tumor.

Reproduction in Domestic Animals, Volume 58, Issue 1, Page 97-108, January 2023., 2023 Abstract Chemical castration, that is the reduction of circulating testosterone concentrations to castrate levels by administration of a GnRH‐agonist implant, is a popular alternative to surgical castration in male dogs. Detailed information concerning the pituitary‐testicular axis following administration of a GnRH‐agonist implant is still scarce ...

Inconsistent stimulation of plasma ACTH through corticotropin-releasing factor in a patient with central Cushing's disease due to pituitary adenoma [PDF]
, 1985 Three uncommon findings were observed in a case of Cushing's disease due to macroadenoma: no suppression of plasma ACTH during an 8-mg dexamethasone test, a negative corticotropin-releasing factor test, and a normal X-ray of the sella turcica.

The Genetics of Pituitary Adenomas [PDF]
, 2011 Cancer is considered a disease of the genome since the development of the vast majority of the human neoplasias is due to the accumulation of gene mutations. Indeed, the vast majority of tumours occur due to a considerable number of mutations that human cells accumulate during lifetime. Approximately 380 genes, representing about 1% of all human genes,
