Rocky Mountain spotted fever (RMSF) takes its name from the characteristic rash that occurs as a consequence of vasculitis associated with rickettsial invasion of the endothelium. The authors examined sera from 14 patients with serologically confirmed RMSF for the presence of antibodies (IgG and
The molecular mechanism of factor Xa (FXa) inhibition by Alboserpin, the major salivary gland anticoagulant from the mosquito and yellow fever vector Aedes albopictus, has been characterized. cDNA of Alboserpin predicts a 45-kDa protein that belongs to the serpin family of protease inhibitors.
BACKGROUND
Familial Mediterranean fever (FMF) is a genetically linked disorder common amongst races of the Eastern Mediterranean region. Typical symptoms include episodic pain syndrome extending throughout the chest or abdomen associated with histopathological signs of amyloidosis of the
The dietary intake of certain fatty acids might contribute to the development of allergic diseases such as hay fever and asthma. We investigated the association between the concentrations of fifteen fatty acids in serum phospholipids, as a marker of dietary intake and metabolism, and hay fever,
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
OBJECTIVE
Hyperthermia induces tumour cell apoptosis through the mitochondrial apoptotic pathway; however, the signal transduction mechanism underlying this process still needs to be fully elucidated. Phospholipid scramblase 3 (PLS3), a target of protein kinase C-delta (PKC-delta), resides in
A 35-year-old woman is referred for right upper quadrant abdominal pain and fever. She had a cholecystectomy for gallstones 4 years previously. An aunt has also had a cholecystectomy. Abdominal ultrasound examination shows numerous hyperechoic foci within the liver and some "comet tail" artifacts.
Homogenates of cardiac left ventricle from malignant hyperthermia-susceptible (MHS) pigs produced a circa 72% more pentane than those from malignant hyperthermia-resistant (MHR) animals, indicating enhanced peroxidation of n-6 fatty acids. This is consistent with the observed circa 70% decrease in
Glomerulonephritis is a rare complication of Q fever and is usually associated with the chronic form of disease, i.e., infectious endocarditis. We describe a 31-year-old man with a self-limited acute febrile illness due to Coxiella burnetii infection who had acute renal failure secondary to
The subjects of the study--patients with severe hemorrhagic fever with renal syndrome--were divided into two groups: those who were on hemodialysis, and those who were not. The study included evaluation of the phospholipid spectrum of erythrocyte membranes in the acute period and during recovery.
Combined antitumour effects of mono- or diacyl ascorbates and heat treatment were studied in comparison with the parent compound, L-ascorbic acid (AsA). At 37 degrees C, 75 microM 6-O-palmitoyl (6P) and 6-O-stearoyl (6S) ascorbates appreciably inhibited DNA synthesis in Ehrlich ascites tumour cells.
In the absence of halothane challenge, incubates of skeletal whole-muscle homogenates from malignant-hyperthermia-susceptible humans and pigs exhibit greater free fatty acid production than controls, which has been attributed to elevated phospholipase A2 activity. The present study examines lipid
A cross-sectional study of the prevalence, significance, and specificity of antibodies to phospholipids (aPL) in patients with Q fever was undertaken in a university-based tertiary care medical center. The results of the lupus anticoagulant (LA) test, VDRL test, fluorescent treponemal antibody
In this study we have investigated the generation of African swine fever (ASF) virus variants resistant to neutralizing antibodies after cell culture propagation. All highly passaged ASF viruses analyzed were resistant to neutralization by antisera from convalescent pigs or antibodies generated
