Abstract:
Domoic acid, an amino acid neurotoxin, produces a single intense resonance Raman peak observed at 1652 cm−1 from aqueous solution when excited at either 242 or 257 nm. The detection limits for domoic acid in water are found to be well within those concentrations determined to be representative of values in toxic phytoplankton cells. Examination of cells known to contain identified large amounts of domoic acid shows that domoic acid spectra are sufficiently intensely excited to allow detection in the presence of normal phytoplankton cell constituents within the cell.

Abstract:
Domoic acid, a structural analogue of kainic acid, has been identified as the toxin that poisoned people who consumed contaminated blue mussels harvested from eastern Prince Edward Island in December of 1987. To investigate the pharmacology of domoic acid in vivo we injected groups of mice with serial dilutions of extracts of contaminated mussels and verified domoic acid concentrations using high performance liquid chromatography. Mice progressed through a series of behavioural changes that were both reproducible and dose-dependent. These behaviours formed the basis of a rating scale that was

Abstract Ten samples of commercial blue mussels (Mytilus edulis) from Japan were analyzed for domoic acid by an indirect competitive enzyme immunoassay (idc–EIA) based on an anti-domoic acid monoclonal antibody. Domoic acid was found in all samples at low concentrations (0.11–1.81 ng/g mussel tissue). The presence of domoic acid was confirmed by liquid chromatography coupled with immunoaffinity chromatography using an anti-domoic acid monoclonal antibody as ligand. To our knowledge, this is the first reported detection of domoic acid, a causative agent of amnesic shellfish poisoning, in Japane

Abstract:
The neurotoxin domoic acid is produced in quantity by the diatom Pseudo-nitzschia multiseries and is released to the environment directly and indirectly via food chains. Presumably there is a mechanism for the biodegradation and disposal of domoic acid and as bacteria are logical candidates for such an activity, a search for bacteria competent to carry out biodegradation of domoic acid was initiated. Extensive trials with a wide variety of bacteria isolated mainly from muds and waters taken from the marine environment showed that the ability to grow on or degrade domoic acid was rare; in fact,

Domoic acid (DA) is a naturally occurring cyanotoxin, which upon ingestion, is responsible for amnesic shellfish poisoning (ASP) in both humans and animals. Produced by the marine diatom, Pseudonitzschia, DA is accumulated by a number of marine organisms including shellfish, clams and mussels which upon consumption can lead to headaches, nausea and seizures. Possessing a variety of functional groups the structure of DA contains three carboxyl groups, a pyrrole ring and a potent conjugated diene region allowing for binding to glutamate receptors in the dorsal hippocampus of the brain causing th

Abstract:
Introduction California sea lion (Zalophus californianus) health is severely compromised by domoic acid toxicosis, which occurs in high levels during harmful algal blooms of Pseudonitzschia australis along the coast of California. Current diagnostic protocols are often inconclusive due to a 2-48 hour window of detectability within the urinary, circulatory, and gastric systems (Cook, et al. 2011 and Monte, Pers Comm, 2012). Past studies suggest that Z. californianus, with domoic acid toxicosis, commonly display abnormal behaviors (Goldstein, et al. 2008). However, many of these abnormal behavio

The excitotoxin domoic acid (DOM) acts at both kainic acid (KA)- and α-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA)-sensitive glutamate receptors. Clinical reports suggest that elderly people are hypersensitive to the neurological effects of DOM intoxication. Young, but not aged hippocampal slices which have been preconditioned with low concentrations of DOM or KA exhibit an acute �tolerance� to subsequent high doses of DOM or KA; application of the selective AMPA agonist fluorowillardiine (FW) fails to induce tolerance to excitotoxins.

Cases of poisoning caused by seafood are common around the world, especially in developing sea and ocean coastal countries. Domoic acid, which became popular with the mass poisoning case in the 1980s, was actually used in alternative treatment practices.

Although poisoning caused by humans attracts more attention, mass poisoning cases caused by other creatures such as sea lions are also important for the ecosystem. Domoic acid poisoning cases are mostly observed after algal blooms. The effects of acute poisoning are fatal a

Innate immune responses in animals and plants involve receptors that recognize microbe-associated molecules. In plants, one set of this defense system is characterized by large families of TIR–nucleotide binding site–leucine-rich repeat (TIR-NBS-LRR) resistance genes. The direct interaction between plant proteins harboring the TIR domain with proteins that transmit and facilitate a signaling pathway has yet to be shown. The Arabidopsis genome encodes TIR-domain containing genes that lack NBS and LRR whose functions are unknown. Here we investigated the functional role of such protein, TLW1 (TI

Abstract:
Loss of function mutations in the farnesyltransferase β subunit gene ERA1 (enhanced response to abscisic acid), cause abscisic acid hypersensitivity in seedlings and in guard cells. This results in slowed water loss of plants in response to drought. Farnesyltransferase (PFT) catalyses the attachment of the 15-carbon isoprenoid farnesyl to conserved cysteine residues located in a conserved C-terminal domain designated CaaX box. PFT is a heterodimeric protein comprised of an a and b sununits. The a subunit is shared between PFT and geranylgeranyltransferase-I (PGGTI) which catalyses the attachem

Abstract:
CRISPR gene editing is a molecular technology that can be used to silence gene expression. In this experiment, genes that are known to play a role in lipid accumulation in hepatocytes were targeted. Specifically, levels of fatty acid transport proteins 2 and 5 (FATP2 & 5) have been shown to be elevated in cases of non-alcoholic fatty liver disease. The goal of this experiment was to reduce expression of these genes by using a dead Cas9 (dCas9) protein with an attached inhibitory domain (KRAB) that acts on the promotor region. When measuring the mRNA expression, it was determined that the l

We have taken a molecular approach to clone cellular targets of calcium/calmodulin (Ca2+/CaM). A 35S-labeled recombinant CaM was used as a probe to screen various cDNA expression libraries. One of the isolated clones from petunia codes for the enzyme glutamate decarboxylase (GAD) which catalyzes the conversion of glutamate to g-aminobutyric acid (GABA). The activity of plant GAD has been shown to be dramatically enhanced in response to cold and heat shock, anoxia, drought, mechanical manipulations and by exogenous application of the stress phytohormone ABA in wheat roots.

Abstract:
The proposed research was directed at determining the activation/binding domains and gene regulation of the PBAN-R’s thereby providing information for the design and screening of potential PBAN-R-blockers and to indicate possible ways of preventing the process from proceeding to its completion. Our specific aims included: (1) The identification of the PBAN-R binding domain by a combination of: (a) in silico modeling studies for identifying specific amino-acid side chains that are likely to be involved in binding PBAN with the receptor and; (b) bioassays to verify the modeling studies using mut

Abstract:
Chair-side rapid detection of mutans streptococci is an important aid to clinical dental caries risk assessment. Rapid Streptococcus mutans detection tools are available on the market but there are a small number. Automutanolysin (Aml) is a peptidoglycan hydrolase whose cell wall-binding domain (CWBD) has substrate-specificity towards mutans streptococci. This study aims to develop a rapid detection assay using CWBD conjugated with horseradish peroxidase (HRP). However, the recombinant protein was as insoluble form. Therefore, magnetic nanoparticles were used as an alternative reporter to conj

Abstract:
Most plants accumulate the nonprotein amino acid, g-aminobutyric acid (GABA), in response to heat stress. GABA is made from glutamate in a reaction catalyzed by glutamate decarboxylase (GAD), an enzyme that has been shown by the Israeli PI to be a calmodulin (CaM) binding protein whose activity is regulated in vitro by calcium and CaM. In Arabidopsis there are at least 5 GAD genes, two isoforms of GAD, GAD1 and GAD2, are known to be expressed, both of which appear to be calmodulin-binding proteins. The role of GABA accumulation in stress tolerance remains unclear, and thus the objectives of th
