A combined morphological and biochemical investigation of mitochondria from developing and rapidly growing tissues ( tumors, fetal, and very early neonatal rat liver) revealed mitochondria which were deficient in respiratory control, showed no valinomycin induced K(+) accumulation or spontaneous Ca(++) uptake, and were unable to undergo a swelling-contraction cycle. Electron microscopic examina...

Abstract Central nervous system (CNS) tumors are the most common solid in children and adolescents. However, neonates aged younger than a year, they very rare. Clinical presentation is often subtle nonspecific. When neurological symptoms apparent at this age, cranial ultrasound (CUS) done as initial evaluation, with standard approach through anterior fontanel (AF), followed by further imaging, ...

BACKGROUND Overexpression of the human c-MYC (MYC) oncogene is one of the most frequently implicated events in the pathogenesis of hepatocellular carcinoma (HCC). Previously, we have shown in a conditional transgenic mouse model that MYC overexpression is restrained from inducing mitotic cellular division and tumorigenesis in the adult liver; whereas, in marked contrast, MYC induces robust prol...
