Investigating heterogeneous PSMA ligand uptake inside parotid glands [PDF]

open access: yesPhysica Medica: European Journal of Medical Physics, 2024
The purpose was to investigate the spatial heterogeneity of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) uptake within parotid glands. We aim to quantify patterns in well-defined regions to facilitate further investigations.

Development of the Pituitary Gland.

open access: yesComprehensive Physiology, 2020
The development of the anterior pituitary gland occurs in distinct sequential developmental steps, leading to the formation of a complex organ containing five different cell types secreting six different hormones. During this process, the temporal and spatial expression of a cascade of signaling molecules and transcription factors plays a crucial role ...

A deep learning classification scheme based on augmented-enhanced features to segment organs at risk on the optic region in brain cancer patients [PDF]

open access: yesarXiv, 2017
Radiation therapy has emerged as one of the preferred techniques to treat brain cancer patients. During treatment, a very high dose of radiation is delivered to a very narrow area. Prescribed radiation therapy for brain cancer requires precisely defining the target treatment area, as well as delineating vital brain structures which must be spared from ...

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

Transcriptional profiling and pathway analysis reveal differences in pituitary gland function, morphology, and vascularization in chickens genetically selected for high or low body weight

open access: yesBMC Genomics, 2019
Background Though intensive genetic selection has led to extraordinary advances in growth rate and feed efficiency in production of meat-type chickens, endocrine processes controlling these traits are still poorly understood. The anterior pituitary gland

Gene Expression and the Physiological Role of Transforming Growth Factor-α in the Mouse Pituitary [PDF]

open access: yes, 2003
Transforming growth factor-alpha (TGF-alpha), a member of the epidermal growth factor (EGF) family, is produced within the mouse anterior pituitaries. However, the cell types of TGF-alpha-expressing cells and the physiological roles of TGF-a within mouse

Oral paltusotine, a nonpeptide selective somatostatin receptor 2 agonist: Mass balance, absolute bioavailability and metabolism in healthy participants

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Paltusotine is a novel, nonpeptide, selective somatostatin receptor 2 agonist in development for the treatment of acromegaly and carcinoid syndrome. This study investigated the mass balance, routes of excretion, absolute bioavailability and metabolite profile of orally administered paltusotine.
