Molecularly imprinted polymers selective for d- and l-phenylalanine have been prepared in water solution using 2-acryloylamido-2,2'-dimethylpropane sulfonic acid bisacryloyl β-cyclodextrin as functional monomers, N,N'-diacryloylpiperazine cross-linker. Polymer−ligand recognition was evaluated a combination of HPLC, displacement chromatography fluorescence spectroscopic studies. HPLC studies revealed that the possess optimal ligand selectivity 30% acetonitrile. The results demonstrate balance...

A method for the rapid estimation of extent complex formation in molecular imprinting pre-polymerization mixtures is described. By use a UV spectroscopy titration procedure, apparent binding constants such self-assembly processes have been obtained. This was used comparison interactions between dipeptide template (N-acetyl-L-phenylalaninyl-L-tryptophanyl methyl ester) and functional monomer methacrylic acid, analogues acetic acid trifluoroacetic acid. The importance template–monomer...

In the present study molecularly imprinted polymers (MIPs) were prepared against a series of structurally related compounds containing various numbers pyridyl groups. The goal, to increase understanding mechanisms recognition in MIPs, was achieved by comparing patterns retention on different MIPs when blank (non-imprinted) polymer high performance liquid chromatography system. Furthermore, frontal analysis carried out three polymers: blank, pyridine-imprinted and 4,4′-bipyridyl-imprinted...

Semiconductor nanowire arrays offer significant potential for biosensing applications with optical read-out due to their high surface area and the unique properties of one-dimensional materials. A challenge analyte-binding nanowires is need efficiently collect detect light from a three-dimensional volume. Here we show that fluorophores attached along several μm long vertical Al2O3 coated gallium phosphide couples into wires, guided them emitted at tip. This enables effective collection by...

A novel molecularly imprinted polymer (MIP) system selective for D-phenylalanine is described where polymerization performed in aqueous solution. The unique comprises a hydrophobic moiety-selective functional monomer, polymerizable β-cyclodextrin, an electrostatic interacting 2-acryloylamido-2-methylpropane sulfonic acid (AMPSA), and the crosslinking agent N,N′-diacryloylpiperazine. Chromatographic evaluation of polymer–ligand recognition characteristics demonstrated ligand selectivity by...

We test previous claims that the bacteria Vibrio alginolyticus produces tetrodotoxin (TTX) when living in symbiosis with nemertean Lineus longissimus by a setup cultivation for TTX production. Toxicity experiments on shore crab, Carcinus maenas, demonstrated presence of paralytic toxin, but evidence from LC-MS and electrophysiological measurements voltage-gated sodium channel–dependent nerve conductance male Wistar rat tissue showed conclusively this effect did not originate TTX. However,...

Abstract Polypeptides from animal venoms have found important uses as drugs, pharmacological tools, and within biotechnological agricultural applications. We here report a novel family of cystine knot peptides nemertean worms, with potent activity on voltage-gated sodium channels. These toxins, named the α-nemertides, were discovered in epidermal mucus Lineus longissimus , ‘bootlace worm’ known longest earth. The most abundant peptide, 31-residue long α-1, was isolated, synthesized, its 3D...

ABSTRACT The proportion of elderly people in the population is increasing, presenting a number new challenges society. purpose this qualitative study was to investigate how persons with motoric eating difficulties perceive and perform their food meal practices everyday life. By using Goffman's concept performance as theoretical framework together Bourdieu's thinking on habitus, deeper understanding obtained. Semi-structured interviews were conducted 14 (aged between 67 87 years) observations...

Three molecular imprinting strategies, each based upon a series of ethylene glycol dimethacrylate (EGDMA) cross-linked co-polymers, have been used to produce materials selective for the commonly analgesic and antipyretic agent paracetamol (p-acetaminophen or 4-acetamidophenol) (1). The polymers were synthesised using either semi-covalent strategy 4-acetamidophenyl-(4-vinylphenyl) carbonate (4) non-covalent on methacrylic acid (MAA) as functional monomer, by employing combination these...

Peptide toxins from marine invertebrates have found use as drugs and in biotechnological applications. Many habitats, however, remain underexplored for natural products, the Southern Ocean is among them. Here, we report one of top predators Antarctic waters: nemertean worm Parborlasia corrugatus (McIntosh, 1876). Transcriptome mining revealed a total ten putative with cysteine pattern similar to that alpha nemertides, four nemertide-beta-type sequences, two novel full-length parborlysins....
