Lucyna Konieczna et al.
Journal of chromatography. A, 1431, 111-121 (2016-01-10)
A simple and sensitive method using dispersive liquid-liquid microextraction (DLLME) followed by liquid chromatography coupled to mass spectrometry (LC-MS) with a hydrophilic interaction chromatography (HILIC) column was developed for the simultaneous determination of 13 compounds of different polarities, comprising monoamine
S Duleu et al.
International journal of Alzheimer's disease, 2010 (2010-08-20)
In Alzheimer's disease, indoleamine 2,3-dioxygenase and tryptophan hydroxylase are known to induce an overproduction of neurotoxic compounds, such as quinolinic acid and 3-hydroxykynurenine from the former, and 5-hydroxytryptophol and 5-methoxytryptophol from the latter. Other compounds, such as kynurenic acid, serotonin
Anthony Y Huang et al.
British journal of pharmacology, 173(21), 3121-3133 (2016-07-29)
Imiquimod is an immunomodulator approved for the treatment of basal cell carcinoma and has adverse side effects, including taste disturbances. Paracrine transmission, representing cell-cell communication within taste buds, has the potential to shape the final signals that taste buds transmit
Andrew N Bubak et al.
PloS one, 11(11), e0166417-e0166417 (2016-11-16)
Ant colonies are distributed systems that are regulated in a non-hierarchical manner. Without a central authority, individuals inform their decisions by comparing information in local cues to a set of inherent behavioral rules. Individual behavioral decisions collectively change colony behavior
Steven Moylan et al.
Brain and behavior, 3(3), 302-326 (2013-06-21)
Multiple studies have demonstrated an association between cigarette smoking and increased anxiety symptoms or disorders, with early life exposures potentially predisposing to enhanced anxiety responses in later life. Explanatory models support a potential role for neurotransmitter systems, inflammation, oxidative and
Naoko Arashida et al.
Analytica chimica acta, 954, 77-87 (2017-01-14)
Amino acids and their related metabolites play important roles in various physiological processes and have consequently become biomarkers for diseases. However, accurate quantification methods have only been established for major compounds, such as amino acids and a limited number of
Jian Zhang et al.
PloS one, 7(1), e30181-e30181 (2012-02-01)
Esophageal adenocarcinoma (EAC) is a rarely curable disease and is rapidly rising worldwide in incidence. Barret's esophagus (BE) and high-grade dysplasia (HGD) are considered major risk factors for invasive adenocarcinoma. In the current study, unbiased global metabolic profiling methods were
Pascal Amireault et al.
PloS one, 8(12), e83010-e83010 (2013-12-21)
Serotonin (5-HT) is a monoamine originally purified from blood as a vasoactive agent. In nonneuronal tissues, its presence is linked with the expression of tryptophan hydroxylase 1 (TPH1) that catalyzes the rate-limiting step of its synthesis. Targeted disruption in mice
Ping Chen et al.
PloS one, 8(8), e71984-e71984 (2013-08-31)
Pigmentation during insect development is a primal adaptive requirement. In the silkworm, melanin is the primary component of larval pigments. The rate limiting substrate in melanin synthesis is tyrosine, which is converted from phenylalanine by the rate-limiting enzyme phenylalanine hydroxylase
Laura Rivard et al.
BMC neuroscience, 11, 22-22 (2010-02-20)
Survival of an animal depends on its ability to match its responses to environmental conditions. To generate an optimal behavioral output, the nervous system must process sensory information and generate a directed motor output in response to stimuli. The nervous
Marta Rysz et al.
Biochemical pharmacology, 99, 113-122 (2015-11-20)
Our recent studies suggest that brain serotonergic system may be involved in the neuroendocrine regulation of cytochrome P450 expression. Intracerebral injection of the serotonergic neurotoxin 5,7-dihydroxytryptamine affected serum hormone concentration and increased the expression and activity of the hormone-dependent isoforms
Md Sharif Shajib et al.
PloS one, 8(8), e72774-e72774 (2013-09-10)
Infiltration of activated immune cells and increased cytokine production define the immunophenotype of gastrointestinal (GI) inflammation. In addition, intestinal inflammation is accompanied by alteration in the numbers of serotonin (5-hydroxytryptamine; 5-HT) synthesizing enterochromaffin (EC) cells and in 5-HT amount. It
Sergio Millán-Plano et al.
International journal of molecular sciences, 11(1), 312-328 (2010-02-18)
Since biological membranes are composed of lipids and proteins we tested the in vitro antioxidant properties of several indoleamines from the tryptophan metabolic pathway in the pineal gland against oxidative damage to lipids and proteins of synaptosomes isolated from the
