Phagocytic cells contain NADPH oxidase that they use for host defense by catalyzing the production of superoxide. Bacterial lipopolysaccharide (LPS) has been found to stimulate NADPH oxidase in mobile and sessile macrophages and microglia. It also evokes fever in homeothermic animals and men, a
Vascular endothelial cells (ECs) lining the blood vessels are the preferred primary targets of pathogenic Rickettsia species in the host. In response to oxidative stress triggered by infection, ECs launch defense mechanisms such as expression of heme oxygenase-1 (HO-1). Previous evidence from an
A single administration of 3,4-methylenedioxymethamphetamine (MDMA, 20 mg/kg, i.p.), induced significant hyperthermia in rats and reduced 5-hydroxytryptamine (5-HT) content and [3H]paroxetine-labeled 5-HT transporter density in the frontal cortex, striatum and hippocampus by 40-60% 1 week later.
BACKGROUND
Alpha lipoic acid is a powerful antioxidant widely used for the supplementary treatment of diabetic neuropathy. Intoxication with alpha lipoic acid is very rare. There is no reported dose of safety in children.
METHODS
A 14-month-old previously healthy girl was referred to our hospital
The aim of this study was to investigate the effects of antioxidants (e.g. alpha-lipoic acid and N-acetyl-L-cysteine) as well as N-methyl-D-aspartate (NMDA) receptor antagonists (e.g. MK-801 and LY235959) on the changes of both core temperature and hypothalamic levels of 2,3-dihydroxybenzoic acid
The heat shock response protects against sepsis-induced mortality, organ injury, cardiovascular dysfunction, and apoptosis. Several inducers of the heat shock response, such as hyperthermia, sodium arsenite, and pyrollidine dithiocarbonate, inhibit NF-kappaB activation and nitric oxide formation.
OBJECTIVE
To report a case of severe cholestatic hepatitis caused by thioctic acid in a patient with diabetic peripheral polyneuropathy and mild chronic renal failure.
METHODS
A 63-year-old man with type 2 diabetes, hypertension, hypothyroidism, and stage 2 chronic renal failure was referred to the
An open, non-randomized phase II study was carried out including all patients treated with whatever chemotherapy or combined modality regimen for whatever cancer who were in clinical objective response or stable disease (SD) for more than three months, to receive maintenance treatment with
The involvement of oxidative mechanisms in the pathogenesis of rickettsiosis was investigated using infection of C3H/HeN mice with sub-lethal and lethal infectious doses of Rickettsia conorii, the causative agent of Mediterranean spotted fever. Microscopic examination of tissues at 48 and 96 h
