TY - JOUR. T1 - Synthesis and characterization of membrane stable bis(arylimino)isoindole dyes and their potential application in nano-biotechnology. AU - Kim, Benjamin. AU - Yalaz, Ceren. AU - Pan, Dipanjan. PY - 2012/8/8. Y1 - 2012/8/8. N2 - A synthetic methodology of preparing novel membrane stable, responsive dyes is revealed in this manuscript. 1,3-Bis(arylimino)isoindole dyes were synthesized and their properties to undergo intramolecular hydrogen bonding was studied with fluorescence spectroscopy in varying solvent polarities. Based on the functional moieties, compound that is capable of hydrogen donor and acceptor interactions produces predominant photoexcitation in comparison to the responsive dyes that lack these functionalities. These dyes, by the virtue of the presence of long chain acyl groups could be incorporated stably within the phospholipids membrane of core-shell nanoparticles. Nanoparticle was cracked to release the dye from a hydrophobic to a hydrophilic environment. A ...

Activation of a calmodulin (CaM)-dependent protein kinase associated with rabbit skeletal-muscle sarcoplasmic reticulum (SR) results in the phosphorylation of polypeptides of 450, 360, 165, 105, 89, 60, 34 and 20 kDa. Radioligand-binding studies indicated that a membrane-bound 60 kDa polypeptide contained both CaM- and ATP-binding domains. Under renaturing conditions on nitrocellulose blots, the 60 kDa polypeptide of the membrane exhibited CaM-dependent autophosphorylation activity, suggesting that it was the CaM-dependent protein kinase of SR. Ca2+/CaM-independent autophosphorylation of polypeptides of 62 and 45 kDa was found to occur in the light SR, whereas the Ca2+/CaM-dependent autophosphorylation activity was enriched in the heavy SR. Both these kinase activities were absent from transverse tubules, although these membranes were enriched in CaM-binding polypeptides of 160, 100 and 80 kDa. In the absence of Ca2+, CaM bound to a 33 kDa polypeptide of the membrane. The purified ryanodine ...

L-Citrulline was measured by high-performance liquid chromatography in 250 coronary effluent samples from 32 hearts before and during exposure to each anesthetic in the absence and presence of 0.1, 1, 10, and 100 nM bradykinin. The high-performance liquid chromatography system consisted of a Laboratory Data Control constametric III G pump (Rivera Beach, FL), a Gilson Automatic Sampler model 231 (Middletown, WI), and an electrochemical detector (BAS LC-4B; Bioanalytical Systems, West Lafayette, IN).

A bioanalytical method for indirect determination of eflornithine enantiomers in 75?µL human plasma has been developed and validated. l- and d-eflornithine were derivatized with o-phthalaldehyde and N-acetyl-L-cysteine to generate diastereomers which were separated on two serially connected Chromolith Performance columns (RP-18e 100 × 4.6?mm i.d.) by a isocratic flow followed by a gradient flow for elution of endogenous compounds. The diastereomers were detected with UV (340?nm). The between-day precisions for L- and D-eflornithine in plasma were 8.4 and 2.3% at 3?µm, 4.0 and 5.1% at 400?µm, and 2.0 and 3.7% at 1000?µm. The lower limit of quantification was determined to be 1.5?µm, at which precision was 14.9 and 9.9% for L- and D-eflornithine, respectively. ...

A simple and highly sensitive procedure is described enabling the simultaneous determination of biogenic polyamines (PAs) and their related monoacetyl derivatives in stomach tissue. The method is based on HPLC using octane sulfonate as an ion-pairing agent employed in acetate buffers at pH 4.5. The application is accompanied with fluorescence detection followed by post-column derivatization with o-phthaldialdehyde at room temperature (20±0.5°C). N1- and N8-acetylspermidines (ASPD) can be determined with this method in the same run without performing any special procedures or pre-purification in concentrations exceeding 8.5 pmoles. The variability in reproducibility of the day-today precision and duplicate determination, and simultaneous determination of standard mixture and biological samples were found < 2%. The mean (± s.e.mean) retention times (n=12) for putrescine (Put), N1-ASPD, N8-ASPD, spermidine (Spd) and spermine (Spm) are 8.97±0.025; 17.64±0.063; 18.99±0.133; 28.20±0.070 and 39.81±0

The hydrolytic and cost efficiencies of five endopeptidases (Alcalase 2.4L, Corolase 7089, Neutrase 0.8L, Promod 671L and Protex 7L) to hydrolyze Atlantic salmon by-products were compared at standardized activity levels based on a casein assay. The substrate was characterized prior to the hydrolytic experiments (pH=6.5, t=50 °C) to obtain substrate-specific constants for nitrogen to protein mass (in g) ratio, i.e. conversion factor fN=5.23 and total amount of peptide bonds (htot)=9.3 mmol per g of protein. At low enzyme activity to substrate ratio, all enzymes were equally efficient in hydrolyzing the substrate. At highest enzyme activity to substrate ratio, Protex 7L, Alcalase 2.4L and Promod 671L gave higher degree of hydrolysis (DH=14.2-14.6 %) than Corolase 7089 (13.2 %) and Neutrase 0.8L (11.6 %) after 120 min of hydrolysis. No differences were observed in protein recovery (yield of solubilized protein) relative to DH. Determination of DH was followed by the pH-STAT and o-phthaldialdehyde ...

Many of the extraction and amino acid analysis methodologies currently employed do not provide complete analysis of all the physiological amino acids and biogenic amines. Extraction procedures frequently employ dilute acid which partially converts gln and asn to glu and asp. A commonly used pre-column derivatizing agent, o-phthalaldehyde, does not react with the imino acids, pro and hydroxypro. The purpose of this investigation was to integrate extraction and analysis procedures into a reliable method for measuring the complete physiological amino acid profiles of fruit and vegetables using HPLC instrumentation commonly available to most laboratories. Water extraction of ground, frozen-thawed tissues effected complete recovery of the physiological amino acids as demonstrated by spiking experiments and tissue combination experiments. HPLC of dabsyl derivatives of the free amino acids allowed their quantification in a selection of fruit and vegetables. Physiological amino acid levels were determined for

BioAssay Systems Protein Assay Kit (QFPR-200) measures total protein.

The electronic absorption bands extend into the 1200-1500 nm ...

4,7-Dihydroisoindole in heterocyclic chemistry is a reduced form of isoindole. 4,7-Dihydroisoindole is a useful building block for extended porphyrins which are relevant as materials for optical applications. An early attempt to access 4,7-dihydroisoindole - the closest relative of thermodynamically unstable isoindole was performed 1985. It was based on the classical Paal-Knorr synthesis under conditions which probably harmed the electron-rich pyrrole ring. Observed instability of 4,7-dihydroisoindole led researchers to conclude that it was not a useful intermediate in the porphyrin chemistry. It turned out that changing the conditions made it possible to isolate 4,7-dihydroisoindole. Three-step synthesis starting from tosylacetylene which includes Diels-Alder reaction, Barton-Zard synthesis and thermal decarboxylation was reported. Though it was expected that under acidic or basic conditions the migration of double bond in 4,7-dihydroisoindole would happen, this does not take when either strong ...

The aim of this study was to investigate an in-capillary derivatization capillary electrophoresis (CE) technique that was performed to determine the concentration of gamma-aminobutyric acid (GABA) and alanine (Ala) in tea after being derivatized with o-phthaldialdehyde/2-mercaptoethanol (OPA/2-ME) to form fluorescence-labeled products. The conditions of labeled derivatization and CE separation were optimized and then applied to real sample analysis. The labeled derivatization with 20 mM OPA and 26.67 mM 2-ME (mol ratio = 0.75) at pH 10 offered the most sensitive detection, and the separation with 30 mM sodium tetraborate buffer (pH 10.0) under 21 kV achieved good selectivity within 14 min. The detections were linear in the range of 0.05-5 mu M with correlation coefficients (R-2) of 0.9995 and 0.9964 and with detection limits of 0.004 and 0.02 mu M for GABA and Ala, respectively. The recoveries were 94.22% (3.58% RSD) and 93.54% (6.46% RSD) for five determinations of GABA and Ala, respectively. ...

The simultaneous determination of 17 free amino acids and 8 biogenic amines in Alicante Monastrell wines was investigated for the first time. The quantification was carried out by using a RP-HPLC method. based on a pre-column derivatization with o-phthaldialdehyde (OPA) and fluorescence detection. From the results obtained it may be concluded that the most abundant free amino acids were Glu, Arg, Ala Asp, and Lys. None of the wine samples analysed had histamine (HIM) or Tyramine (TYM) levels above the limits considered as a possible toxic risk for healthy individuals. No measurable amounts of cadaverine (CAD) or methylamine (MEA) were found, showing no spoilage symptoms of sensory properties of the wines. Tryptamine (TRM) content was significantly higher in aged wines compared to young wines. However ethanolamine (ETA) content was lower. These data were used to make a preliminary classification of the samples using cluster analysis. (C) 2012 Elsevier Ltd. All rights reserved ...

FDA believes that certain sterilizers and disinfectant devices, such as Cetylcide-G, may help reduce this risk of viral exposure based on FDAs current understanding of these devices and SARS-CoV-2. Because sterilization processes render devices free from viable microorganisms including baterial spores, and because disinfection kills most recognized pathogenic microorganisms, it can generally be inferred that sterilization and disinfection should minimize the viability of SARS-CoV-2 on surfaces. More information is available here: https://www.fda.gov/sterilizers-disinfectant-devices-coronavirus.

The bactericidal effect of disinfectants against biofilms is essential to reduce potential endoscopy-related infections caused by contamination. Here, we investigated the bactericidal effect of a high-level disinfectant, peracetic acid (PAA), against Staphylococcus aureus and Pseudomonas aeruginosa biofilm models in vitro. S. aureus and P. aeruginosa biofilms were cultured at 35 °C for 7 days with catheter tubes. The following high-level disinfectants (HLDs) were tested: 0.3% PAA, 0.55% ortho-phthalaldehyde (OPA), and 2.0% alkaline-buffered glutaraldehyde (GA). Biofilms were exposed to these agents for 1-60 min and observed after 5 min and 30 min by transmission and scanning electron microscopy. A Students t test was performed to compare the exposure time required for bactericidal effectiveness of the disinfectants. PAA and GA were active within 1 min and 5 min, respectively, against S. aureus and P. aeruginosa biofilms. OPA took longer than 10 min and 30 min to act against

According to the authors of OSAPs Mission Guide, the Peracetic Acid based product available in powder form that is listed in the humanitarian guide is Perasafe made by Antec International ( http://www.antechh.com ).

Antiseptics, disinfectants, and sterilants are a diverse group of germicides used to prevent the transmission of microorganisms to patients (Table 104-1). Although these terms are sometimes used interchangeably and some of these xenobiotics are used for both antisepsis and disinfection, the distinguishing characteristics between the groups are important to emphasize. An antiseptic is a chemical that is applied to living tissue to kill or inhibit microorganisms. Iodophors, chlorhexidine, and the alcohols (ethanol and isopropanol) are commonly used antiseptics. A disinfectant is a chemical that is applied to inanimate objects to kill microorganisms. Bleach (sodium hypochlorite), phenolic compounds, formaldehyde, hydrogen peroxide liquid, ortho-phthalaldehyde, and quaternary ammonium compounds are examples of currently used disinfectants. Neither antiseptics nor disinfectants have complete sporicidal activity. A sterilant is a chemical that is applied to inanimate objects to kill all microorganisms ...

Prostate circulating tumor cells (PCTCs) in circulation are shed from either a primary tumor or metastases, which are directly responsible for most prostate cancer deaths. Quantifying exfoliated PCTCs may serve as an indicator for the clinical management of prostate cancer, isolating and removing of PCTCs could potentially reduce prostate cancer metastasis, and culturing and characterizing captured PCTCs could facilitate the development of personalized treatment options. Prostate-specific membrane antigen (PSMA) is an established biomarker for prostate cancer being strongly expressed on prostate tumor cells associated with high-grade primary, androgen independent, and metastatic tumors. ...

A cascade of simple mechanisms influences thalamic innervation of the neocortex. The cortex exerts a remote growth-promoting influence on thalamic axons when they start to grow out, becomes growth-permissive when the axons begin to invade, and later expresses a stop signal, causing termination in layer 4. However, any part of the thalamus will innervate any region of developing cortex in culture, and the precise topographic distribution of thalamic fibres in vivo is unlikely to depend exclusively on regional chemoaffinity. The handshake hypothesis proposes that axons from the thalamus and from early-born cortical preplate cells meet and intermingle in the basal telencephalon, whereafter thalamic axons grow over the scaffold of preplate axons, and become captured for a waiting period in the subplate layer below the corresponding part of the cortex. The bizarre pattern of development of thalamic innervation in the mutant reeler mouse provides strong evidence that thalamic axons are guided by

Quantitatively inhibited hexokinase contains approx. 1 mol of dye per mol of monomer of mol.wt. 51000. The inhibition is irreversible and activity cannot be recovered on incubation with high concentration (20 mM) of ATP or D-glucose. 4. Mg2+ protects the enzyme against inactivation by Procion Green H-4G but enhances the rate of inactivation by all the other ...
