Wide attention has been given to hyperthermia as a new measure for cancer treatment. Clinical trials of hyperthermia, as they possess antitumour activity on some occasions. When cells were incubated with oleic we examine if fatty acids exert a synergistic effect on Ehrlich ascites tumour cells when
An improved gas chromatography with mass spectrometry procedure was developed to highlight the esterified fatty acids in 100 μL blood of dengue fever patients in the early febrile phase versus healthy volunteers. 24 adult patients and 24 healthy volunteers were included in this study. The recoveries
Malignant hyperthermia is caused by an abnormal increase in Ca2+ levels in skeletal muscle in response to anesthetics, including halothane. Since fatty acid production is elevated in skeletal muscle from individuals with malignant hyperthermia, the effects of fatty acids on the threshold of
The production of pro-inflammatory cytokines, such as interleukins 1 and 6 and tumour necrosis factors, occurs rapidly following trauma or invasion of the body by pathogenic organisms. The cytokines mediate the wide range of symptoms associated with trauma and infection, such as fever, anorexia,
In this study we evaluated the biting deterrent effects of a series of saturated and unsaturated fatty acids against Aedes aegypti (L), yellow fever mosquito (Diptera: Culicidae) using the K & Dbioassay module system. Saturated (C6:0 to C16:0 and C18:0) and unsaturated fatty acids (C11:1 to C14:1,
Hyperthermia-induced cell lethality is thought to be mediated through injury to the cell membrane. Membrane perturbation results in the release of prostaglandins (PG) and leukotrienes (LT). These compounds are potent biological mediators and may modify the tumor microenvironment and therapeutic
Actual consumption of vitamins A, E, beta-carotene, ascorbic acid, thiamin, pyridoxine and main foodstuffs by recovered patients suffered from hemorrhagic fever with renal syndrome has been given. Frequency analysis of foodstuffs consumption was used to study actual nourishment of recovered
Based on studies in swine, the malignant hyperthermia syndrome has been postulated to result from an enhanced sensitivity (low threshold) of the Ca2(+)-induced Ca2(+)-release process. However, fatty acid production is elevated in homogenates of skeletal muscle from pigs and humans susceptible to
The quantitative distribution of cell surface alterations of heated P388 ascites tumour cells was determined by scanning electron microscopy. Cells harvested from host animals maintained on a standard rodent chow diet or one high in saturated fatty acids responded differently, to identical
The effects of free fatty acids in the blood on osmotic fragility and water content of erythrocytes when combined with hyperthermia were investigated. The isotonic buffer, containing the fatty acid, was added to the erythrocyte suspension to a final concentration of 200 microM/l. The samples were
Dengue virus (DENV) is the most prevalent human arthropod-borne virus and causes severe problems worldwide, mainly in tropical and sub-tropical regions. However, there is no specific antiviral drug against DENV infection. We and others recently reported that stearoyl-CoA desaturase-1 (SCD1)
Hyperthermic sensitivities of Escherichia coli B/r and Bs-1 were determined for lag-, midlog-, and stationary-phase cells at 47, 48, and 49 degrees C. In both strains midlog-phase cells were strikingly more heat sensitive (100-fold greater killing after 4 h at 48 degrees C) than stationary-phase
The influence of membrane fluidity on hyperthermic cell killing has been investigated in ascites tumor cells. Membrane lipid composition of P388 ascites tumor cells were modified by feeding host animals with diets containing either unsaturated fatty acids (UFA) or saturated fatty acids (SFA). Both
In our view, the initial effect of hyperthermia on cells is the disorganization of the membrane lipid. Such disorganization alters the membrane's biophysical properties leading to passive changes in transmembrane permeability, shifts in surface charge, and altered stereoorganization of
Outbreaks of hypersensitivity pneumonitis or humidifier fever were attributed to the inhalation of organic material aerosolized by a chilled-water spray humidification system. The purpose of this study was to isolate and characterize the serologically detectable antigen(s) present in extracts
