HPTLC-FLD-SERS as a facile and reliable screening tool: Exemplarily shown with tyramine in cheese.

Numai utilizatorii înregistrați pot traduce articole

The serious cytotoxicity of tyramine attracted marked attention as it induced necrosis of human intestinal cells. This paper presented a novel and facile high performance thin-layer chromatography (HPTLC) method tailored for screening tyramine in cheese. Separation was performed on glass backed

N‑trans‑ρ‑caffeoyl tyramine isolated from Tribulus terrestris exerts anti‑inflammatory effects in lipopolysaccharide‑stimulated RAW 264.7 cells.

Numai utilizatorii înregistrați pot traduce articole

Inflammation is induced by the expression of cyclooxygenase‑2 (COX‑2), which is an important mediator of chronic inflammatory diseases, such as rheumatoid arthritis, asthma and inflammatory bowel disease. Tribulus terrestris (T. terrestris) is known to have a beneficial effect on inflammatory

Tumor necrosis factor expressed by primary hippocampal neurons and SH-SY5Y cells is regulated by alpha(2)-adrenergic receptor activation.

Numai utilizatorii înregistrați pot traduce articole

Neuron expression of the cytokine tumor necrosis factor-alpha (TNF), and the regulation of the levels of TNF by alpha(2)-adrenergic receptor activation were investigated. Adult rat hippocampal neurons and phorbol ester (PMA)-differentiated SH-SY5Y cells were examined. Intracellular levels of TNF

Comparative analysis of the in vitro cytotoxicity of the dietary biogenic amines tyramine and histamine.

Numai utilizatorii înregistrați pot traduce articole

Tyramine and histamine, the most toxic biogenic amines (BA), are often found in high concentrations in certain foods. Prompted by the limited knowledge of BA toxicity, and increasing awareness of the risks associated with high intakes of dietary BA, the in vitro cytotoxicity of tyramine and

Involvement of bradykinin, cytokines, sympathetic amines and prostaglandins in formalin-induced orofacial nociception in rats.

1. This study characterises some of the mechanisms and mediators involved in the orofacial nociception triggered by injection of formalin into the upper lip of the rat, by assessing the influence of various treatments on behavioural nociceptive responses (duration of facial rubbing) elicited either

Preclinical profiles of the novel reversible MAO-A inhibitors, moclobemide and brofaromine, in comparison with irreversible MAO inhibitors.

Numai utilizatorii înregistrați pot traduce articole

Acceptance into clinical practice of monoamine oxidase (MAO) antidepressants requires unequivocal evidence that novel, non-hepatotoxic and reversible MAO-A inhibitors carry little or no risk of inducing severe hypertensive crises (cheese effect). This study summarizes the most relevant preclinical

EXPERIMENTAL STUDIES ON INFLAMMATION : II. EXPERIMENTAL CHEMICAL INFLAMMATION IN VIVO.

Numai utilizatorii înregistrați pot traduce articole

1. None of the salts tested produce a marked inflammation in vivo in concentrations under 10 per cent. Potassium salts and the different citrates produced atypical inflammatory reactions in mice, but not in frogs. There was no true inflammation, however, characterized by blood vessel changes,

Genetically engineered myoblast sheet for therapeutic angiogenesis.

Numai utilizatorii înregistrați pot traduce articole

Peripheral arterial disease is a common manifestation of systemic atherosclerosis, which results in more serious consequences of ischemic events in peripheral tissues such as the lower extremities. Cell therapy has been tested as a treatment for peripheral ischemia that functions by inducing

Rapid transfer of endothelial cell sheet using a thermosensitive hydrogel and its effect on therapeutic angiogenesis.

Numai utilizatorii înregistrați pot traduce articole

In this study, thermosensitive hydrogels incorporated with multiple cell-interactive factors were developed as a substrate to form monolayer of human umbilical vein endothelial cells (HUVECs) that can be detached and transferrable to target sites as a cell-sheet in response to temperature change.

Activity-guided isolation of NF-κB inhibitors and PPARγ agonists from the root bark of Lycium chinense Miller.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The root bark of Lycium chinense Miller, Lycii radicis cortex, has been used in traditional Chinese medicine (TCM) to treat different inflammation-related symptoms, such as diabetes mellitus. The pro-inflammatory transcription factor nuclear factor kappa B (NF-κB) is a key regulator of

Catecholamine cardiomyopathy: review and analysis of pathogenetic mechanisms.

Numai utilizatorii înregistrați pot traduce articole

Catecholamines given in high concentrations produce myocardial damage in several mammalian species. The histological changes are similar to those found in patients given large amounts of pressor agents and in those who develop pheochromocytomas. They include myofiber necrosis, myofibrillar

Counter effects of Asiaticosids-D through putative neurotransmission on rotenone induced cerebral ganglionic injury in Lumbricus terrestris.

Numai utilizatorii înregistrați pot traduce articole

Asiaticoside-D (AD) was shown to efficacy of ganglionic degenerated Lumbricus terrestris as a pioneering observation in our earlier research. Though, extract molecular mechanisms of AD for degenerative diseases (DDs) remains largely unknown. We investigated the neuroprotective effects of AD

Sympathetic Vasoconstrictor Responsiveness of the Leg Vasculature During Experimental Endotoxemia and Hypoxia in Humans.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Sympathetic vasoconstriction regulates peripheral circulation and controls blood pressure, but sepsis is associated with hypotension. We evaluated whether apparent loss of sympathetic vasoconstrictor responsiveness relates to distended smooth muscles or to endotoxemia and/or

Acetyl Eburicoic Acid from Laetiporus sulphureus var. miniatus Suppresses Inflammation in Murine Macrophage RAW 264.7 Cells.

Numai utilizatorii înregistrați pot traduce articole

The basidiomycete Laetiporus sulphureus var. miniatus belongs to the Aphyllophorales, Polyporaceae, and grows on the needleleaf tree. The fruiting bodies of Laetiporus species are known to produce N-methylated tyramine derivatives, polysaccharides, and various lanostane triterpenoids. As part of our

Alpha-adrenoceptor stimulation with exogenous norepinephrine or release of endogenous catecholamines mimics ischemic preconditioning.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Brief episodes of ischemia induced by proximal coronary artery occlusion can precondition the myocardium. Whether other stressful stimuli have the potential to protect the myocardium from subsequent ischemia remains controversial. RESULTS To study the hypothesis that transient
