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
We investigated the efficacy of hyperthermia and gamma-linolenic acid on experimental carcinoma. This study focused on polyunsaturated fatty acids that are substrates for free radical reactions. Oleic acid, linolenic acid, alpha-linolenic acid, or gamma-linolenic acid was injected into the arteries
The formation and mineralisation of bone are two critical processes in fast-growing Atlantic salmon (Salmo salar). The mechanisms of these processes, however, have not been described in detail. Thus, in vitro systems that allow the study of factors that influence bone formation in farmed Atlantic
Twenty-five years ago prostaglandin (PG) F2 alpha was identified as the first cyclooxygenase-derived metabolite of polyunsaturated fatty acid metabolism in the bovine central nervous system (CNS). On the other hand, 12-hydroxyeicosatetraenoic acid (12-HETE) was the first lipoxygenase product of
The sensitivity of the solid mammary adenocarcinomas CA755 and MtGB, grown in the medial aspect of the hind legs of host mice, to local hyperthermia (43.5 +/- 0.1 degrees C for 1 hr) was increased by feeding the host mice a diet enriched in linoleic acid. The enhanced sensitivity was expressed only
The aim of the article is to study actual ration of patients suffered from hemorrhagic fever with renal syndrome (HFRS) and its interaction with the development of arterial hypertension (AH). 296 men aged 20–59 suffered from HFRS were under the care of physician within the period of 1 to 6 years.
OBJECTIVE
To study the time course of visual cell damage resulting from hyperthermic light exposure and the possible involvement of rod outer segment (ROS) lipids in the process.
METHODS
Rats were acclimated in darkness for 2 hours in a hyperthermic chamber to elevate core body temperature and then
N-3 polyunsaturated fatty acids reduce the synthesis of IL-1, the main molecule responsible for fever. We speculate that this action may be used as a prophylactic in preventing febrile seizures in susceptible children.
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
BACKGROUND
Allergies have become more prevalent globally over the last 20 years. Dietary consumption of n-3 (or omega 3) long chain polyunsaturated fatty acids (LCPUFA) has declined over the same period of time. This, together with the known role of n-3 LCPUFA in inhibiting inflammation, has
Arachidonic acid (AA), a representative ω6-polyunsaturated fatty acid (PUFA), is a precursor of 2-series prostaglandins (PGs) that play important roles in inflammation, pain, fever, and related disorders including cardiovascular diseases. Eating fish or supplementation with the ω3-PUFAs such as
Nonsteroidal anti-inflammat ory drugs (NSAIDs) are one of the drug types frequently prescribed for their analgesic, anti-inflammatory, and antithrombotic actions, but carry a risk of major gastroduodenal damage from mild erosive changes to serious ulceration leading to fatal outcomes. From the long
Homogenates of semitendinosus muscle from malignant hyperthermia (MH)-susceptible pigs produced threefold more pentane than those from MH-resistant pigs, indicating enhanced free radical-mediated peroxidation of n-6 fatty acids. This did not reflect a deficiency in tissue antioxidants or
The present study was designed to determine the effect of eicosapentaenoic acid (EPA) on the susceptibility of tumor cells to treatments that kill the cells by lipid peroxidation. Using AH109A carcinoma, a rat liver cancer, we measured EPA content, levels of antioxidants, and degree of lipid
Polyunsaturated fatty acids have important structural roles in cell membranes. They are also intermediates in the synthesis of biologically active molecules such as eicosanoids, which mediate fever, inflammation, blood pressure and neurotransmission. Arachidonic and docosahexaenoic acids are
