Importance of fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in detection of post-thyroidectomy recurrence in differentiated thyroid cancer with negative radio-isotope iodine scan, yet, elevated serum thyroglobulin level

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background Thyroid cancer considered the 6th common cancer in female and represents approximately 1% of all cancers. Thyroid cancer is generally characterized by good prognosis, long term survival and low aggressiveness. Its prognosis is related to tumor

LncRNAs has been identified as regulators of Myeloid-derived suppressor cells in lung cancer

open access: yesFrontiers in Immunology, 2023
Lung tumours are widespread pathological conditions that attract much attention due to their high incidence of death. The immune system contributes to the progression of these diseases, especially non-small cell lung cancer, resulting in the fast ...

Dcf1 Deficiency Attenuates the Role of Activated Microglia During Neuroinflammation

open access: yesFrontiers in Molecular Neuroscience, 2018
Microglia serve as the principal immune cells and play crucial roles in the central nervous system, responding to neuroinflammation via migration and the execution of phagocytosis. Dendritic cell-derived factor 1 (Dcf1) is known to play an important role
