n acetyl l cysteine/fever

It has been shown that staphylococcal enterotoxin A (SEA) acts through human peripheral blood mononuclear cells (PBMC) to stimulate synthesis or release of pyrogenic cytokines. Nuclear factor-kappa B (NF-kappaB) is thought to play an important role in inflammatory responses through the regulation of

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

Hyperthermia (HT) enhances the anti-cancer effects of radiotherapy (RT), but the precise biochemical mechanisms involved are unclear. This study was aim to investigate if mild HT sensitizes colorectal cancer cells to RT through reactive oxygen species (ROS)-inducing autophagic cell death in a mice

Regional hyperthermia has potential for human cancer treatment, particularly in combination with systemic chemotherapy or radiotherapy. The mechanisms involved in heat-induced cell killing are currently unknown. Hyperthermia may increase oxidative stress in cells, and thus, oxidative stress could

Mild hyperthermia enhances anti-cancer effects of chemotherapy, but the precise biochemical mechanisms involved are not clear. This study was carried out to investigate whether mild hyperthermia sensitizes gastric cancer cells to chemotherapy through reactive oxygen species-induced autophagic death.

N-Acetyl-l-cysteine (NAC) is a well-known medication, primarily used as a mucolytic agent in pulmonary disease. Recently, we have found that NAC possesses antipyretic properties. The aim of the present study was to investigate the mechanism by which NAC attenuates fever. The concentration of

Photodynamic therapy (PDT) is a cancer treatment that make use of the cancer-specific accumulation of porphyrins. We have reported that mitochondrial reactive oxygen species (mitROS) upregulate uptake transporter of porphyrins, heme carrier protein-1 (HCP-1). The accumulation of cancer-specific

In response to many stresses and pathologic states, including different models of nervous system injury, cells synthesize a variety of proteins, most notably the inducible 72 kDa heat shock protein 70 (Hsp70), which plays important roles in maintaining cellular integrity and viability. We report

Induction of the heat shock proteins (HSPs) is involved in the increased resistance to cancer therapies such as chemotherapy and hyperthermia. We used two human ovarian cancer cell lines; a cisplatin (CDDP)-sensitive line A2780 and its CDDP-resistant derivative, A2780CP. The concentration of

Exposure to 3, 4-methylenedioxymethamphetamine (MDMA) leads to spatial memory impairment and hippocampal cell death. In the present study we have examined the protective effects of N-acetyl-L-cysteine (NAC) on MDMA-induced neurotoxicity. A total of 56 male Sprague Dawley rats (200-250 g) received

Current study was attempted to assess whether hyperbaric oxygen pretreatment or treatment exerts its antipyresis by reducing circulating interleukin-6 and hypothalamic glutamate, hydroxyl radicals and prostaglandin-E(2) in rabbits. It was found that systemic administration of lipopolysaccharide

Existing evidence suggests that oxidative insults and antioxidant defense mechanisms play a critical role in the host cell response during infection of endothelial cells by Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever. Heme oxygenase (HO), a rate-limiting enzyme in the

Hyperthermia is used in cancer treatment and potentiates the cytotoxicity of radiation and certain chemotherapy drugs. The mechanism(s) of heat killing and those involved in heat potentiation of cytotoxic modalities are not understood. This study examines whether heat shock causes a redox imbalance,
