tryptamine/necrosis

When trinitrophenylated (TNP) hepatocytes and lipopolysaccharide (LPS) are intravenously injected into TNP-liver protein sensitized guinea pigs, massive hepatic cell necrosis was induced in most of mice. Using this experimental acute hepatic failure model, the tryptophan metabolism in the liver,

When heat-killed Propionibacterium acnes, a gram-positive anaerobe, is intravenously injected into mice followed by an intravenous injection of gram-negative lipopolysaccharide (LPS) 7 days later, most of the mice die of massive hepatic cell necrosis within 24 hours of LPS injection. Using this

β-phenylethylamine and tryptamine are biogenic amines (BA) often found in foods. In general, BA are assumed to be toxic and their accumulation in food is not recommended. However, present knowledge regarding the toxicity of β-phenylethylamine and tryptamine is limited; more information is needed if

In this study, we present multiple lines of evidence to support a critical role for heparin-bound EGF (epidermal growth factor)-like growth factor (HB-EGF) and tumor necrosis factor-alpha-converting enzyme (TACE) (ADAM17) in the transactivation of EGF receptor (EGFR), ERK phosphorylation, and

OBJECTIVE Chronic oxidative stress and subacute inflammation have been implicated as causes of age-related macular degeneration (AMD). In this study, we tested whether an orally available 5-OH-tryptamine (5HT) 1a receptor agonist, xaliproden, could protect against retinal pigment epithelium (RPE)

A comparison of the acute toxicity and a histological examination of the toxic effects in mouse of 4,7-; 5,6-; 5,7- and 6,7-dihydroxytryptamines and related compounds are present. A time and dose dependent induction of subepicardial lesions by 5,6-dihydroxytryptamine is demonstrated. The development

OBJECTIVE Eight peptide dendrimers were designed as structural mimics of natural cationic amphiphilic peptides with antifungal activity and evaluated for their anti-Candida potential against the wild type strains and mutants. METHODS Dendrimer 14 containing four Trp residues and dodecyl tail and a

Among all types of pollution, heavy metals are considered the greatest threat to human health, and heavy metals are associated with an increased risk of cardiovascular disease, coronary heart disease and neurodegenerative disorders. Manganese (Mn) exposure is well reported to exert neurotoxicity and

Increasing evidence hints to the central role of neuroinflammation in the development of post-stroke depression. Danger signals released in the acute phase of ischemia trigger microglial activation, along with the infiltration of neutrophils and macrophages. The increased secretion of

Obesity and osteoporosis are two alarming health disorders prominent among middle and old age populations, and the numbers of those affected by these two disorders are increasing. It is estimated that more than 600 million adults are obese and over 200 million people have osteoporosis worldwide.

Burkholderia cepacia complex strains are genetically related but phenotypically diverse organisms that are important opportunistic pathogens in patients with cystic fibrosis (CF,) as well as pathogens of onion and banana, colonizers of the rhizospheres of many plant species, and common inhabitants

Semicarbazide-sensitive amine oxidase (SSAO) is known to increase during in vitro adipogenesis and to be one of the most highly expressed membrane proteins of white adipocytes. Although less well documented, mitochondrial monoamine oxidases (MAOs) are also present in adipocytes and share with SSAO
