Herpes simplex encephalitis (HSE) is a serious disease with 10-20% mortality and high rate of neuropsychiatric sequelae. This study is a long-term, nationwide study in a single country, Iceland. Clinical data were obtained from patient records and from DNA PCR and antibody assays of CSF. Diagnosis of HSE was classified as definite, possible or rejected based on symptoms, as well as virological,...

Allele-specific extension reactions (ASERs) use 3' terminus-specific primers for the selective extension of completely annealed matches by polymerase. The ability of the polymerase to extend non-specific 3' terminal mismatches leads to a failure of the reaction, a process that is only partly understood and predictable, and often requires time-consuming assay design. In our studies we investigat...

Herpetic encephalitis (HSE) is one of the most severe infection of the central nervous system (CNS), connected with high mortality rate, even when appropriate therapy has been introduced. Better understanding of pathomechanisms responsible for neuronal injury during the course of the disease can be useful in the assessment of the risk of the occurrence of severe complications, as well as in pot...

Introduction. Herpes simplex esophagitis is well recognized in immunosuppressed subjects, but it is infrequent in immunocompetent patients. We present a case of HSE in a 53-year-old healthy man. Materials and Methods. The patient was admitted with dysphagia, odynophagia, and retrosternal chest pain. An esophagogastroduodenoscopy revealed minute erosive area in distal esophagus and biopsies conf...

Expansions in sensory systems usually require processes such as gene duplication and divergence, and thus evolve slowly. We evaluate a novel mechanism leading to rapid sensory repertoire expansion: hybrid-sensory expansion (HSE). HSE occurs when two species with differently tuned sensory systems form a hybrid, bringing together alleles from each of the parental species. In one generation, a sen...

Heme oxygenase-1 is an essential enzyme in heme catabolism, and its human gene promoter contains a putative heat shock element (HHO-HSE). This study was designed to analyze the regulation of human heme oxygenase-1 gene expression under thermal stress. The amounts of heme oxygenase-1 protein were not increased by heat shock (incubation at 42 degrees C) in human alveolar macrophages and in a huma...

Transgenic tobacco expression was analysed of chimeric genes with point mutations in the heat shock element (HSE) arrays of a small heat shock protein (sHSP) gene from sunflower: Ha hsp17.7 G4. The promoter was developmentally regulated during zygotic embryogenesis and responded to heat stress in vegetative tissues. Mutations in the HSE affected nucleotides crucial for human heat shock transcri...

Herpes simplex virus encephalitis (HSE) is the most common fatal sporadic encephalitis in humans. HSE is primarily caused by herpes simplex virus (HSV)-1 infection of the brain. HSE results in increased levels of oxidative stress, including the production of reactive oxygen species, free radicals, and neuroinflammation. The most biologically active form of vitamin E (VE) is alpha-tocopherol (al...

Objective: To elucidate the value of early computed tomographic (CT) signs of stroke in predicting the occlusion site in the cerebral arteries. Patients: 105 consecutive patients with acute embolic stroke affecting the anterior circulation. Methods: Four early signs were evaluated on cranial CT within six hours of stroke onset: loss of the insular ribbon (LIR); attenuation of the lentiform nucl...

Selective malignant cell invasion at secondary sites mediated by organspecific (paracrine) motility factors may be of importance in preferential organ colonization of metastatic cells. In this study we isolated and exam ined a migration-stimulating activity present in mouse hepatic sinusoidal endothelial cell-conditioned medium (HSE-CM). HSE-CM contains mi gration-stimulating activity for highl...
