Dedicated hippocampal inhibitory networks for locomotion and immobility [PDF]

open access: yes, 2017
Network activity is strongly tied to animal movement; however, hippocampal circuits selectively engaged during locomotion or immobility remain poorly characterized.

Role of cyclic AMP in the control of cell-specific gene expression [PDF]

open access: yes, 1993
Genes have to be expressed in specific cell types at appropriate times of development dependent on external signals. cAMP signaling occurs in all cells, thus raising the question of how this signal transduction pattern is integrated into mechanisms ...

An Update on DOTA-Peptides PET Imaging and Potential Advancements of Radioligand Therapy in Intracranial Meningiomas

open access: yesLife
Meningiomas arise from the meningeal layers covering the central nervous system structures. Although most are benign, meningiomas can still cause neurological morbidity due to the mass effect and compression of the surrounding parenchyma.

Contemporary nuclear medicine diagnostics of neuroendocrine tumors [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2015
The new positron emission tomography (PET/CT) methods for neuroendocrine tumors detection are presented and compared with classic, conventional methods. Conventional methods use a gamma scintillation camera for patients with neuroendocrine tumor

Advances in Parahydrogen‐Induced Polarization for Nuclear Magnetic Resonance of Peptides, Proteins, and Biopolymers

open access: yesChemistryEurope, EarlyView.
Hyperpolarization by parahydrogen‐induced polarization enhances the sensitivity of nuclear magnetic resonance spectroscopy of amino acids, peptides, mini‐proteins, and biopolymers using nonnatural amino acids with unsaturated side chains up to three orders of magnitude.

PET tracers for somatostatin receptor imaging of neuroendocrine tumors: current status and review of the literature.

open access: yesFuture Oncology, 2014
Neuroendocrine tumors have shown rising incidence mainly due to higher clinical awareness and better diagnostic tools over the last 30 years. Functional imaging of neuroendocrine tumors with PET tracers is an evolving field that is continuously refining ...

Current Status of Radiopharmaceuticals for the Theranostics of Neuroendocrine Neoplasms

open access: yesPharmaceuticals, 2017
: Nuclear medicine plays a pivotal role in the management of patients affected by neuroendocrine neoplasms (NENs). Radiolabeled somatostatin receptor analogs are by far the most advanced radiopharmaceuticals for diagnosis and therapy (radiotheranostics ...
