Yanrong Zhou et al.
Veterinary microbiology, 250, 108839-108839 (2020-10-02)
Like obligate intracellular parasites, viruses co-opt host cell resources to establish productive infections. Polyamines are key aliphatic molecules that perform important roles in cellular growth and proliferation. They are also needed for the successful multiplication of various viruses. Little is...
Frank Madeo et al.
Autophagy, 6(1), 160-162 (2010-01-30)
Spermidine is a ubiquitous polycation that is synthesized from putrescine and serves as a precursor of spermine. Putrescine, spermidine and spermine all are polyamines that participate in multiple known and unknown biological processes. Exogenous supply of spermidine prolongs the life...
Julia Torres et al.
Organic & biomolecular chemistry, 13(27), 7500-7512 (2015-06-13)
Within all the eukaryotic cells myo-inositol phosphates (InsPs) are an important group of biomolecules that are potentially related to signaling functions. The most abundant member of this family in nature is InsP6 (phytate, L(12-) in its fully deprotonated form). The...
Elvira S Plakidi et al.
Foods (Basel, Switzerland), 9(5) (2020-05-14)
Monitoring of biogenic amines in food is important for quality control, in terms of freshness evaluation and even more for food safety. A novel and cost-effective method was developed and validated for the determination of the main biogenic amines: histamine...
Yong Kee Choi et al.
European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology, 19(2), 77-84 (2008-10-11)
Levels of ionotropic glutamate (Glu) N-methyl-d-aspartic acid (NMDA), 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propionic acid (AMPA), and kainic acid (KA) receptors in forebrain regions of juvenile rats (age 42 days) were quantified after 3 weeks of treatment with three different doses of risperidone (0.3, 1.0...
L L Vindeløv et al.
Cytometry, 3(5), 323-327 (1983-03-01)
A new modification of our detergent technique for the preparation of nuclei for flow cytometric DNA analysis is described. The attainment of low coefficients of variation of the peaks and of quantitative staining of nuclei from different tissues was a...
Shruti Shukla et al.
Journal of food science, 80(8), M1794-M1803 (2015-07-07)
To select appropriate microorganisms as starter cultures for the reliable and reproducible fermentation of soybean fermented products of Korean Doenjang, various ratios of fungi (Aspergillus oryzae J, Mucor racemosus 15, M. racemosus 42) combined with Bacillus subtilis TKSP 24 were...
H C Ha et al.
Proceedings of the National Academy of Sciences of the United States of America, 95(19), 11140-11145 (1998-09-16)
The polyamines are small organic cations that are absolutely required for eukaryotic cell growth. Although their growth requirements are well established, the molecular functions of the polyamines are ill-defined. Oxidative damage to DNA by reactive oxygen species is a continual...
G Brent Dawe et al.
Neuron, 102(5), 976-992 (2019-05-06)
Neurotransmitter-gated ion channels are allosteric proteins that switch on and off in response to agonist binding. Most studies have focused on the agonist-bound, activated channel while assigning a lesser role to the apo or resting state. Here, we show that nanoscale...
Alexis Goichon et al.
The American journal of clinical nutrition, 102(2), 359-367 (2015-06-26)
Amino acids are well known to be key effectors of gut protein turnover. We recently reported that enteral delivery of proteins markedly stimulated global duodenal protein synthesis in carbohydrate-fed healthy humans, but specifically affected proteins remain unknown. We aimed to...
Tadeu Chaves de Figueiredo et al.
Talanta, 142, 240-245 (2015-05-25)
A quantitative and confirmatory high-performance liquid chromatography with ultraviolet detection (HPLC-UV) method for the determination of bioactive amines in the albumen and yolk of commercial eggs was developed, optimized and validated by analyte extraction with trichloroacetic acid and pre-column derivatization...
Desiree Bailey et al.
Pharmacology, biochemistry, and behavior, 133, 57-64 (2015-04-01)
The aim of this study was to examine the acute effect of a range of novel hydroxycinnamic acid derivatives of spermine on the development of spermine-induced CNS excitation and convulsions in female Laca mice, and to assess the chronic adverse...
Tsuyoshi Minami et al.
Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 31(7), 721-724 (2015-07-15)
This study is the first to report on the detection of biogenic amines in an aqueous solution using an organic field-effect transistor (OFET) device with an extended gate electrode modified with a layer of diamine oxidase and a horseradish peroxidase...
E Bergers et al.
Journal of clinical pathology, 49(11), 931-937 (1996-11-01)
Conflicting results have been reported concerning the prognostic value of DNA flow cytometric variables (DNA ploidy, DNA index, %S phase fraction) in breast cancer. Selection bias and differences in treatment may have contributed to these conflicting prognostic results. Differences in...
J Griffith et al.
Biochemistry, 24(1), 158-162 (1985-01-01)
The RecA protein of Escherichia coli, whether pure or in a crude cell lysate, will rapidly form small crystals (microcrystals) in the presence of low concentrations of spermidine. We describe the conditions of time, pH, and polyamine concentration over which...
A S Jackson et al.
The British journal of nutrition, 40(3), 497-504 (1978-11-01)
1. Skinfold thickness, body circumferences and body density were measured in samples of 308 and ninety-five adult men ranging in age from 18 to 61 years. 2. Using the sample of 308 men, multiple regression equations were calculated to estimate...
Enzo Agostinelli et al.
International journal of oncology, 45(3), 1109-1122 (2014-06-28)
It has been confirmed that multidrug resistant (MDR) melanoma cells (M14 ADR2) are more sensitive than their wild-type counterparts (M14 WT) to H2O2 and aldehydes, the products of bovine serum amine oxidase (BSAO)-catalyzed oxidation of spermine. The metabolites formed by...
Kiarash Riazi et al.

Peripheral inflammatory diseases are often associated with behavioral comorbidities including anxiety, depression, and cognitive dysfunction, but the mechanism for these is not well understood. Changes in the neuronal and synaptic functions associated with neuroinflammation may underlie these behavioral abnormalities. We...
