Atypical hemolytic uremic syndrome (HUS) is a rare disorder in children, therefore it may lead to misdiagnosis, delay in treatment, or acute kidney injury. Patients with atypical HUS present signs and symptoms of hemolytic anemia, thrombocytopenia, and higher lactate dehydrogenase and uric acid levels. The main risk factor highlighted is consanguinity, gene mutations, and viral infections. Ecul...

The immunocytochemical localization of the base excision repair en zyme uracil DNA glycosylase was examined as a function of cell prolif eration. Two nontransformed normal human fibroblast cell strains were analyzed using an anti-human uracil DNA glycosylase monoclonal anti body. In quiescent cells, basal levels of a nonnuclear immunocytochemically reactive glycosylase protein were detected. No...

AIMS To establish whether PAb248 recognises human p53 as well as murine p53 and if so, to determine its distribution in normal tissues. METHODS The ability of PAb248 to recognise human p53 was established by analysis of the human osteosarcoma derived Saos-2 cell line, which lacks the p53 gene, before and after transfection with p53 cDNA, using western blotting and immunoprecipitation. Immunos...

The VP1 subunit of the picornavirus capsid is the major antigenic determinant and mediates host cell attachment and virus entry. To investigate the localisation of Theiler's murine encephalomyelitis virus (TMEV) VP1 during infection, a bioinformatics approach was used to predict a surface-exposed, linear epitope region of the protein for subsequent expression and purification. This region, comp...

Bartonella bacilliformis was continuously internalized into human endothelial cells beginning shortly after addition of the bacteria and continuing for at least 24 h after infection in vitro, with a major increase in uptake occurring between 16 and 24 h. Preincubation of endothelial cells with C3 exoenzyme, which inactivated intracellular Rho-GTPase, blocked internalization of the bacteria. Add...

Cocaine is a popular recreational drug in the United States, and up to 70% of the seized cocaine contains levamisole which is an antihelminthic that can cause cutaneous vasculitis with necrosis and positive antineutrophil cytoplasmic antibodies (ANCAs). Here, we report a unique case of recurrent cocaine-induced vasculitis in a patient who smokes cocaine for more than 20 years. A 38-year-old wom...

Anti-leucine-rich glioma inactivated-1 (LGI1) limbic encephalitis (LE) is a rare neurological disorder that has a subacute course of progressive encephalopathy and fasciobrachial dystonic seizures. We report a patient with anti-LGI1 LE that presented with atypical manifestations that complicated the diagnosis. A 62-year-old woman presented with a chronic course of memory disturbance and a subse...

INTRODUCTION A ntiglomerular basement membrane (GBM) disease is an autoimmune disease that classically presents as a rapidly progressive crescentic glomerulonephritis, with or without pulmonary hemorrhage, and typically does not relapse. The anti-GBM autoantibodies, typically polyclonal IgG1 and IgG4, bind to the noncollagenous 1 domain of the alpha-3 chain of type IV collagen that is present o...
