Biogenic Amine Analysis of Fresh and Stored Bluefish (Pomatomus Saltatrix) and Microbiological Survey of Histamine-Forming Bacte
Changes in histamine, putrescine, and cadaverine concentrations in fresh and stored bluefish (Pomatomus saltatrix) were determined using a new HPLC method. The HPLC method utilized a 5.0% (w/v) trichloroacetic acid (TCA) extraction, pre-column fluorescamine derivitization, and fluorescence …

Uncovering astrocyte roles at the blood brain barrier in the healthy and concussed brain
… in the cortex and leakage of the small molecule Cadaverine and large plasma protein fibrinogen, which are normally contained by a functional BBB. Vessels within regions of ablated astrocytes showed reduced expression of the tight junction protein zonula occludens-1, indicating impairment of the …

The D-domain of fibrin : structural and functional studies
… fibrin clotted in the presence of 2.45 mM dansyl cadaverine, a fluorescent lysine analogue. Fluorescent-D-monomer was a by-product of f-D-dimer purification, the yield being determined by the concentration of dansyl cadaverine. At 2.45 mM f-D-monomer was always present in the digest. The …

Analysis of Biogenic Amines by GC/FID and GC/MS
… 3, but day 5 showed average levels of 160 pm (cadaverine), 1000 ppm (histamine), and 350 ppm (tyramine). Good precision of six amine stardards at 50 ppm was shown: heptylamine 5.2%, putrescine 5.6%, cadaverine 5.0%, histamine 9.9%, tyramine 5.1%, and spermidine 6.2% RSD.

High-Throughput Discovery of Stimuli of Bacterial Two-Component Systems from the Human Gut Microbiome
… a candidate sensor of the microbial metabolite cadaverine. We characterize both divalent metal sensing TCSs as homologs of bacterial copper sensors with relaxed metal specificity and amino acid substitutions in metal-binding sites. We characterize specificity of our candidate cadaverine sensor …

The development of chemically engineered pullulan for drug delivery
… step were: hexadecylamine, decylamine, cadaverine (1-5 diaminopentane), and three jeffamine® (polyoxypropylenediamine) compounds of differing molecular weights (230, 400 and 2000). Results concluded that all six pullulan derivatives show an increase in reduced viscosity to varying …

Mechanistic Study of Antimicrobial Cyclic Peptide [R4W4] Antibacterial Effectiveness against Methicillin-resistant Staphylococcus aureus (MRSA)
… effects. Lastly, in the presence of BODIPY-Cadaverine fluorescence dyes, [R<sub>4</sub>W<sub>4</sub>] reveals binding affinity to LTA comparable with melittin, the positive control. In addition, a change in the antibacterial activity of [R<sub>4</sub>W<sub>4</sub>] against MRSA in the …

Mechanistic Studies of Flavin-Dependent Monooxygenases Involved in Bacterial Defense and Plant Metabolism
… and is favored over the aliphatic diamine cadaverine and amino acid L-ornithine. The three-dimensional structure of FbsI was solved and shown to have similarities to other NMOs, and characterization of active site mutants revealed residues essential for catalysis and cofactor specificity. …

Characterization of the Diverse Substrate Specificities and Biological Roles of Polyamine Biosynthetic Enzymes in Microorganisms
… presence of the reaction products putrescine and cadaverine to 1.7 and 2.15 Å, respectively. The overall structure is similar to eukaryotic ODC, however reorientation of the 310-helix enlarges the substrate binding-pocket, thereby allowing L-lysine to be accommodated. The structure of the …

Studio della maturazione di formaggi pecorino stagionati in stabilimento e in grotta
… Pecorino cheese (2-phenilethylamine, putrescine, cadaverine, hystidine, tyramine, spermine and spermidine). Further analysis were undertaken in order to track the lipid profile evolution, reporting the concentration of the cheese free fatty acids in object, in relation with ripening time, …

The Effects of Aging on EGFR/pSTAT3-Dependent Gliovascular Structural Plasticity
… by extravasation of 70kDa FITC and the ~1kDa Cadaverine, suggesting that BBB integrity was compromised. These findings led to the objective of this dissertation, which was to determine if focal ablation of an astrocyte is sufficient to disrupt BBB integrity. By utilizing the in vivo 2Phatal …
