There is thought to be a genetic defect within the calcium release channel of the sarcoplasmic reticulum in malignant hyperthermia (MH). This primary alteration is hypothesized to influence the function and/or structure of various muscle membrane systems; e.g., to have a direct effect on the
The most typical alteration of membrane phospholipids in rat tissues in acute hyperthermia was an increase in content of sphingomyelin and phosphatidylinositol. The increase in phosphatidylinositol appears to occur as a result of unspecific effect of hyperthermia on the cells, while the increase of
Thermal stability of erythrocyte membrane is a measure for its ability to maintain permeability barrier at deleterious conditions. Hence, it could impact the resistance of erythrocytes against detrimental factors in circulation. In this study the thermostability of erythrocyte membranes was
Spermatogenesis is known to be vulnerable to temperature. The aim of this study was to investigate the effects on testicular lipids of the transient germ cell loss that is induced by mild testicular hyperthermia. Adult rat testes were exposed once a day to 43 °C for 15 min for 5 days and the effects
Relapsing fever borreliae require lipid compounds for growth in vitro. In this study, the major pathways of lipid catabolism in three species of tick-borne relapsing fever borreliae were investigated. Thin-layer chromatography was used to compare chloroform-methanol extracts of fresh culture media
We recently reported that a mild heat shock induces a long lasting stimulation of TRAIL-induced apoptosis of leukemic T-lymphocytes and myeloid cell lines, but not normal T-lymphocytes, which correlates with an enhanced ability of TRAIL to recognize its receptors. As shown here, this phenomenon
Reye syndrome, characterized by acute encephalopathy, selective liver damages, a fatty degeneration in visceral organs and miserable prognosis, is probably caused by various drugs, especially antipyretic such as acetylsalicylate. The incidence of the disease has been decreased by prohibition of
Chilling injury is the major limiting factor for successful cryopreservation of both human and animal oocytes. Maternal hyperthermia is the main reason for summer infertility in dairy cows. In this paper, we will present evidence for the involvement of membrane lipid composition and its
In this review, potential roles for the endogenous sphingolipid, sphingosine, and its derivatives are described for muscle cells. Sphingosine modulates the function of important calcium channels in muscle, including the ryanodine receptor (RyR) calcium release channel of the sarcoplasmic reticulum
Alphaviruses are mosquito-borne, enveloped, plus-strand RNA viruses that cause a spectrum of diseases in humans that include fever, rash, arthritis, meningitis, and encephalomyelitis. Sindbis virus (SINV) is the prototype alphavirus, causes encephalomyelitis in mice, and provides a model system for
Chikungunya virus (CHIKV) is a rapidly spreading, enveloped alphavirus causing fever, rash and debilitating polyarthritis. No specific treatment or vaccines are available to treat or prevent infection. For the rational design of vaccines and antiviral drugs, it is imperative to understand the
Flaviviruses are emerging arthropod-borne pathogens that cause life-threatening diseases such as yellow fever, dengue, West Nile encephalitis, tick-borne encephalitis, Kyasanur Forest disease, tick-borne encephalitis, or Zika disease. This viral genus groups >50 viral species of small enveloped plus
OBJECTIVE
Enzyme replacement therapy with olipudase alfa (recombinant human acid sphingomyelinase) is being developed for Niemann-Pick disease type B (NPD B).
METHODS
A single-center, open-label, nonrandomized, single-ascending-dose trial evaluated the safety of intravenous olipudase alfa (0.03-1.0
Fever is the most common reason that children present to Emergency Departments. Clinical signs and symptoms suggestive of bacterial infection are often non-specific, and there is no definitive test for the accurate diagnosis of infection. The 'omics' approaches to identifying biomarkers from the
