Around 47-74% of patients with hereditary hemorrhagic telangiectasia (HHT) have hepatic vascular malformations (HVMs); magnetic resonance images (MRI) of the central nervous system (CNS) might show in T1 sequences a hyper-intensity signal in different areas, mainly in the basal ganglia (BG) as
BACKGROUND
Zinc (Zn), copper (Cu) and manganese (Mn) are involved in regulatory systems in the cell. Their role in neuromodulator activities and redox reactions has been implicated in the pathogenesis of neurological disorders. The aim of this study was to determine changes of Zn, Cu and Mn levels
Dietary iron deficiency enhances the absorption of iron, cobalt, manganese, zinc, cadmium and lead, whereas, iron deficiency due to bleeding increases the absorption of iron, cobalt and perhaps manganese. To determine whether the response to bleeding is qualitatively different from that induced by
A 44 year old right handed woman complained of difficulty in moving. She and her relatives had skin telangiectasia or recurrent epistaxis. On neurological examination, she had a mask-like facies and bradykinesia in both extremities. Laboratory examinations showed iron deficiency anaemia and mild
Intracerebral hemorrhage (ICH) is a subtype of stroke with high disability and mortality. Dexmedetomidine (Dex) has been shown to provide neuroprotection in several neurological diseases. The aim of present study was to investigate the effects of Dex on ICH-induced neurological BACKGROUND
Human immune cells generate large amounts of reactive oxygen species (ROS) throughout the respiratory burst that occurs during inflammation. In inflammatory bowel diseases, a sustained and abnormal activation of the immune system results in oxidative stress in the digestive tract and in a
In the present in vitro and in vivo study we investigated the pro-oxidant effects of hemoglobin, as well as the antioxidant effects of its metabolites, in the brain. Incubation of rat brain homogenates with hemoglobin (0-10 microM) but not hemin induced lipid peroxidation up to 24 h (EC50 = 1.2
Shiga toxin (Stx), the main virulence factor of Shiga toxin producing Escherichia coli, is a major public health threat, causing hemorrhagic colitis and hemolytic uremic syndrome. Currently, there are no approved therapeutics for these infections; however manganese has been reported to provide
Background. For the burn surgeon, the treatment of necrotizing soft tissue infections is one of the most demanding surgical emergencies, requiring "radical excisions" of the infected tissue and reconstruction. During the infection period, the excised sites are treated with application of gauzes
The study of morphological features of tissue organs of experimental animals after a single intragastric administration of an aqueous suspension nanodis-dispersed manganese (III, IV) at doses of 2000, 3500 and 5000 mg/kg showed complex of morphological changes in the form of circulatory disorders up
We present two patients with hereditary hemorrhagic telangiectasia (HHT) accompanied by multiple hepatic arteriovenous malformations (AVMs) whose cranial MRI demonstrated high signal intensity in the basal ganglia on T1-weighted images. Manganese levels in peripheral blood were very high in both
The signal abnormalities found on MRI in the basal ganglia in patients with an increased plasmatic level of manganese are well known. We report a case with a hyperintense signal in a patient with a high plasmatic level of manganese due to long term parenteral nutrition. The normal signal intensity
Exposure of Colisa fasciatus, a freshwater teleost, to 2500 mg/l manganese sulphate for 90 h caused decreased spermatogenic activity and hemorrhage in the testes.
Hemorrhage rapidly increases the expression of proinflammatory and immunoregulatory cytokines in the lungs. Binding elements for the nuclear transcriptional regulatory factors (NF)-kappa B and NF-IL6 (C/EBP beta) are present in the promoter regions of multiple cytokine genes, including those whose
Oxidative stress has been proposed as a possible mechanism involved in manganese (Mn) toxicity. Using natural antioxidants against metal-induced hepatotoxicity is a modern approach. The present study investigated the beneficial role of silymarin, a natural flavonoid, in Mn-induced hepatotoxicity
