Primary papillary tumors of the central nervous system are rare. We have encountered a series six pineal region with distinctive features that appear to represent clinicopathologic entity. The occurred in four women and two men, ranging age from 19 53 years. Imaging studies showed large well-circumscribed mass region. were characterized by an epithelial-like growth pattern, which vessels covered layer tumoral cells. In areas, neoplastic cells large, columnar or cuboidal, clear cytoplasm....

Hepatic encephalopathy (HE) is a neuropsychiatric complication of liver failure. Previous studies described astroglia alterations in HE, but regional changes have not been well investigated. This study addresses astroglial response by exploring glial fibrillary acidic protein (GFAP) immunoreactivity cortical structures including somatosensory (S1Tr and S1BF), piriform (Pir), perirhinal (PRh) cortices, subcortical regions corpus callosum (CC), ventromedial thalamus (VMT), mammillothalamic...

Neurosteroids are cholesterol-derived molecules synthesized within the brain, which exert trophic and protective actions. Infection by human feline immunodeficiency viruses (HIV FIV, respectively) causes neuroinflammation neurodegeneration, leading to neurological deficits. Secretion of neuroinflammatory host viral factors glia infiltrating leukocytes mediates principal neuropathogenic mechanisms during lentivirus infections, although effect neurosteroids on these processes is unknown. We...

Hepatic encephalopathy (HE) is a neuropsychiatric complication of both acute and chronic liver failure characterized by progressive neuronal inhibition. Some neurosteroids are potent positive allosteric modulators the gamma-aminobutyric acid (GABA)-A receptor complex, 'increased GABAergic tone' has been proposed to explain neuroinhibition characteristics HE. Brain levels pregnenolone, allopregnanolone tetrahydrodesoxycorticosterone (THDOC) functional status GABA-A complex were assessed in...

Abstract Fatigue is one of the most common non‐specific symptoms associated with several disease states including liver diseases. Recently, it was reported that levels progesterone metabolites such as allopregnanolone (3α,5α‐tetrahydroprogesterone; 3α,5α‐THP) and isopregnanolone (3β,5α‐THP) were increased in plasma patients chronic fatigue syndrome. We hypothesize THP might be commonly observed evaluated scores five 16 primary biliary cirrhosis (PBC), 12 hepatitis C (CHC) 11 age‐matched...
