A putative thymidylate kinase gene of African swine fever virus has been identified at the left end of the SalI I' fragment of the virus genome. The gene, designated A240L, has the potential to encode a protein of 240 amino acids with an M(r) of 27,754 and is transcribed early after infection.
Serial passage of yellow fever 17D virus (YF5.2iv, derived from an infectious molecular clone) on mouse neuroblastoma (NB41A3) cells established a persistent noncytopathic infection associated with a variant virus. This virus (NB15a) was dramatically reduced in plaque formation and exhibited
1. The acute hyperthermia induced by exposure to elevated ambient temperatures (40 degrees C) during 90 min produced dramatic changes in certain brain transmitter amino acid levels in infant rats. 2. All inhibitor transmitter amino acids except taurine, rose significantly in 7 and 14 day-old rats.
Dengue virus infection causes life-threatening hemorrhagic fever. Increasing evidence implies that dengue viral nonstructural protein 1 (NS1) exhibits a tendency to elicit potentially hazardous autoantibodies, which show a wide spectrum of specificity against extracellular matrix and platelet
The aim of the present experiment was to evaluate the role played by aspartic acid and glutamic acid of frontal cerebral cortex during the hyperthermia induced by prostaglandin E1. Two groups of six Sprague Dawley male rats were anaesthetized with ethyl-urethane. The frontal cortical concentrations
Persistent infection of mouse neuroblastoma NB41A3 cells with yellow fever 17D virus generates viral variants which exhibit defective cell penetration, poor cell-to-cell spread, small plaque size and reduced growth efficiency, caused by substitution of glycine for aspartic acid or glutamic acid at
Severe fever with thrombocytopenia syndrome virus (SFTSV) is a novel phlebovirus responsible for causing an emerging zoonotic disease. We previously established subclones from SFTSV strain YG1 based on differences in low-pH-dependent cell fusion activities and found two amino acid substitutions,
Pestivirus nonstructural protein 2 (NS2) is a multifunctional, hydrophobic protein with an important but poorly understood role in viral RNA replication and infectious virus production. In the present study, based on sequence analysis, we mutated several representative conserved residues within the
Theophylline-associated convulsions have been observed most frequently in children with fever, but the mechanism is not fully understood. In this study, we investigated the basic mechanism of aminophylline [theophylline-2-ethylenediamine]-induced convulsions and the effects of Brewer's yeast-induced
Monodispersed Fe3O4 magnetic nanoparticles (MNPs) having size of 7 nm have been prepared from iron oleate and made water dispersible by functionalization for biomedical applications. Three different reactions employing thioglycolic acid, aspartic acid and aminophosphonate were performed on oleic
The high performance and increased tumor-targeting accumulation of magnetic nanocrystals (MNCs) are the most important considerations in cancer targeted magnetic hyperthermia (TMH). To achieve these goals, our study was firstly done using well-established fluorescence/magnetic Mn-Zn ferrite MNCs
Brain temperatures (Tbr) of male Wistar rats were recorded at every 15 min interval for 24 h, prior to the destruction of the medial septal (MS) neurons with N-methyl-D-aspartic acid, and on the 7th, 14th and 21st days after the destruction. The capacity of the rats to regulate their body
Background: COVID-19 is not fully known and causes severe inflammation and cytokine storm. It has many symptoms, such as: fever, sore throat, headache, dyspnoea, and diarrhoea. Arbidol was used in the treatment of COVID19, which was the
The Exaltation of Newcastle disease virus (END) phenomenon is induced by the inhibition of type I interferon in pestivirus-infected cells in vitro, via proteasomal degradation of cellular interferon regulatory factor (IRF)-3 with the property of the viral autoprotease protein N(pro). Reportedly, the
A 29-year-old female was admitted under section 2 of the mental health act with an acute psychosis. Her condition deteriorated as she developed a fever and worsening hallucinations. Brain imaging was normal but a lumbar puncture revealed a reactive cerebrospinal fluid. A transvaginal ultrasound
