TY - JOUR. T1 - Basic carboxyl groups of hemoglobin S. T2 - Influence of oxy-deoxy conformation on the chemical reactivity of Glu-43(β). AU - Rao, M. Janardhan. AU - Acharya, A. Seetharama. PY - 1991/2/1. Y1 - 1991/2/1. N2 - The γ-carboxyl groups of Glu-43(β) and Glu-22(β) of hemoglobin-S (HbS), two intermolecular contact residues of deoxy protein, are activated by carbodiimide at p H 6.0. The selectivity of the modification by the two nucleophiles, glycine ethyl ester (GEE) and glucosamine, is distinct. Influence of N-hydroxysulfosuccinimide, a reagent that rescues carbodiimide-activated carboxyl (O-acyl isourea) as sulfo-NHS ester, on the overall selectivity and efficiency of the coupling of Glu-22(β) and Glu-43(β) with nucleophiles has been investigated. Sulfo-NHS increases the extent of coupling of nucleophiles to HbS. The rescuing efficiency of sulfo-NHS(increase in modification) with GEE and galactosamine as nucleophiles is 2.0 and 2.8, respectively. In the presence of sulfo-NHS, the ...

Highly porous 45S5 bioactive glass-based scaffolds were fabricated by the foam replica technique and coated with collagen by a novel method. After an initial cleaning step of the bioactive glass surface to expose reactive –OH groups, samples were surface functionalized by (3-aminopropyl)triethoxysilane (APTS). Functionalized scaffolds were immersed in a collagen solution, left for gelling at 37 °C, and dried at room temperature. The collagen coating was further stabilized by crosslinking with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and N-hydroxysuccinimide (NHS). Applying this coating method, a layer thickness of a few micrometers was obtained without affecting the overall scaffold macroporosity. In addition, values of compressive strength were enhanced by a factor of five, increasing from 0.04 ± 0.02 MPa for uncoated scaffolds to 0.18 ± 0.03 MPa for crosslinked collagen-coated scaffolds. The composite material developed in this study exhibited positive cell (MG-63)
TY - JOUR. T1 - Inactivation of neutrophil NADPH oxidase upon dilution and its prevention by cross-link and fusion of phox proteins. AU - Miyano, Kei. AU - Kitahara, Hiroki. AU - Ohmi, Shinobu. AU - Kakinuma, Katsuko. AU - Tamura, Minoru. PY - 2004/11/1. Y1 - 2004/11/1. N2 - Activation of the phagocyte NADPH oxidase involves assembly of p47 phox, p67 phox, Rac, and flavocytochrome b 558, and the activation can be triggered in a cell-free system with an anionic amphiphile. We find that the activated oxidase in a pure cell-free system was rapidly inactivated upon dilution. When the activated oxidase was treated with a chemical cross-linker, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, the half-life of the oxidase in dilution was extended from 1 min to 4 h at 25°C. The cross-linked oxidase was resistant to inhibition by inactive flavin analogs, indicating that cross-linking prevents flavin exchange. When a fusion protein p67N-p47N plus RacQ61L was added, flavocytochrome b 558 became ...
Bicomponent electrospun nanofibers based on the combination of synthetic (i.e., aliphatic polyesters such as polycaprolactone (PCL)) and natural proteins (i.e., gelatin) have been extensively investigated as temporary platforms to instruct cells by the release of molecular/pharmaceutical signals for the regeneration of several tissues. Here, water soluble proteins (i.e., gelatin), strictly embedded to PCL, act as carriers of bioactive molecules, thus improving bioavailability and supporting cell activities during in vitro regeneration. However, these proteins are rapidly digested by enzymes, locally produced by many different cell types, both in vitro and in vivo, with significant drawbacks in the control of molecular release. Hence, we have investigated three post-processing strategies based on the use of different crosslinking agents-(1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride) (EDC), glyceraldehyde (GC), and 1,4-butanediol diglycidyl ether (BDDGE)-to delay the dissolution time of
The 1H NMR spectrum for compound 4a in d6-DMSO at 70 °C demonstrates signals characteristic for the glycine ethyl ester and the resorcin[4]arene scaffold. The signal related to the methylene group of the ethyl ester at 4.12 ppm appears as a quartet, integrating to 16. The signal associated with the methyl group of this ester at 1.20 ppm is a triplet, integrating to 24. The signal related to the α-protons (Fig. 7) appears as two pairs of doublets at 3.96 ppm and 3.85 ppm, each of these integrates to eight. The signal for the amide NH protons for this derivative appears as a triplet at 7.72 ppm, integrating to eight.. The signal for the methylene protons (H5) of the OCH2CO groups appears as two doublets at 4.36 ppm and at 4.27 ppm, each of these signals integrates to eight. This splitting could be attributed to the presence of two glycine residues on each aromatic ring. The signals related to the protons of aromatic rings (H3 and H4) appear as two singlets at 6.73 ppm for H3 protons and at 6.57 ...

Non-glutaraldehyde fixation of an organ or a prosthesis for implantation in a mammal is based upon carbodiimide treatment. A solution containing a sterilizing agent, such as EDC, in combination with a coupling enhancer, such as Sulfo-NHS, and a high concentration of a diamine cross linking agent is used. As a result, only minimal surface reduction occurs during fixation, and the resultant products show a dramatic increase in resistance to calcification.

Purpose: To develop a sustained delivery system to improve the release kinetics of vancomycin as well as its therapeutic effectiveness to prevent postoperative corneal infection.. Methods: Vancomycin was incorporated into an engineered collagen hydrogel (10 and 15 wt%) scaffold through N-ethyl-N-[3-dimethylaminopropyl] carbodiimide/N-hydroxy succinimide (EDC/NHS) crosslinking technique. Vancomycin incorporation into the collagen hydrogel was examined by fourier transform infrared spectroscopy (FTIR) and quantified spectrophotometrically after collagen digestion with collagenase. Mechanical stability of hydrogel was measured by Instron instrument. In vitro release profile of vancomycin was measured in PBS at 37°C. Structural integrity of released vancomycin was assessed by circular dichroism (CD) spectroscopy. The minimum inhibitory concentration (MIC) of control and released vancomycin against S.aureus (SA) was determined by inoculating with bacterial suspension (106 colony-forming unit/ml). ...
The use of protein cross-linking agents during bonding procedures has been recently proposed to improve bond durability. This study aimed to use zymography and in situ zymography techniques to evaluate the ability of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) cross-linker to inhibit matrix metalloproteinase (MMP) activity. The hypotheses tested were that: (1) bonding procedures increase dentin gelatinolytic activity and (2) EDC pre-treatment prevents this enzymatic activity. The zymographic assay was performed on protein extracts obtained from dentin powder treated with Optibond FL or Scotchbond 1XT with or without 0.3M EDC pre-treatment. For in situ zymography, adhesive/dentin interfaces were created with the same adhesives applied to acid-etched dentin slabs pre-treated or not with EDC conditioner. Zymograms revealed increased expression of dentin endogenous MMP-2 and -9 after adhesive application, while the use of EDC as a primer inactivated dentin gelatinases. Results of in situ zymograpy
Human recombinant collagen can be cross-linked with a variety of chemical cross-linking agents. Cross-linking methods can be tuned to confer collagen-based scaffolds with specific physical properties, improved antigenicity and thermal stability without impeding the ability of the material to integrate into the surrounding tissue and to promote regeneration. Here, we describe a method to cross-link human recombinant collagen using a water soluble carbodiimide. Carbodiimides are referred to as zero-length cross-linking agents as they are not incorporated into the final cross-link and thus pose minimal risk with respect to cytotoxicity. The resulting collagen-based scaffold possesses properties comparable to that of the human cornea and is thus suitable for use as a corneal substitute.. ...
Human serum albumins modified by covalently bound tolmetin or zomepirac were synthesized as models for similar products formed in vivo from acyl glucuronides. Activated esters of both drugs were prepared with 1-ethyl-3-(3-dimethylaminopropyl)-carbodi-imide, and then allowed to react with human serum albumin. Tryptic digests of both protein products were analysed by HPLC to identify peptides containing covalently bound drugs, and binding sites on albumin were identified by high-performance tandem MS. Three binding sites were common to both products, i.e. lysine-195, -199 and -351. Three further modified residues were identified for the tolmetin-albumin product, i.e. aspartic acid 1, and lysine-524 and -536. ...
0281] Materials Preparation--To activate the labeling beads, one ml of 0.2 μm Time Resolved Fluorescence latex microparticles (MPs) (Thermo Fisher Fremont, Calif.) at 10% (w/v) solids are combined with 1 ml of 0.5 M MES buffer (pH 6.0), 5.5 ml of deionized H20, 2.3 ml of 50 mg of N-hydroxysuccinimide (ISIHS; Product #24500; Pierce Chemical Company, Rockford, Ill.) per ml deionized H2O and 0.2 ml of 5 mg of 1-ethyl-3-(3-dimethylamino-propyl) carbodiimide hydrochloride (EDC; Product #22980; Pierce Chemical Company) in deionized H2O. The resultant mixture is sonicated on ice for 40 seconds and then allowed to react on a shaker at RT for 30 minutes. The activated MPs are then centrifuged at 100 C at 10,000×g and washed three times with cold 50 mM MES buffer (pH 6.0) by resuspension and centrifugation cycles. In a typical procedure, the final pellet of MPs is suspended in 3.7 ml of 50 mM MES buffer (pH 6.0) and 2.3 ml of 1.0 mg of mouse anti-(Anti-NTproBNP peptide 63-71 antibody (Hytest., Turku, ...
Synthesis As previously stated, glutamine is a nonessential amino acid. In the body, glutamine is synthesized from glutamate via the enzyme glutamine synthestase (GS) and through the addition of ATP and ammonia. (See Figure). Glutamate + ATP + NH3 → Glutamine + ADP + phosphate + H20 The incorporation of ammonia into glutamate is an amidation type reaction and the hydrolysis of ATP to ADP drives the reaction forward. ATP is directly involved in the reaction because it phosphorylates the carboxyl group on the side chain of glutamate and forms an acyl-phosphate intermediate (See Figure: Glutamine Final). The acyl-phoshphate intermediate reacts with free ammonia and forms glutamine. Glutamine synthetase (GS) plays a major role because a high-affinity binding-site for ammonia is formed in GS after the formation of the intermediate to prevent hydrolysis of the intermediate. Hydrolysis of the intermediate would not yield glutamine and thus waste a valuable molecule of ATP. Functions Glutamine is a ...
Laccase was covalently immobilised to activated carbon using four derivatisation methods. The highest bound activity was obtained using diimide coupling of laccase to carboxyl groups on the carbon. The maximum bound activity was reached at 11.5 mg laccase/g carbon; the maximum protein bound was 42.85 mg/g carbon. The carbon-immobilised laccase (CIL) was stable at pH values from 4.0 to 9.0. CIL stored at 4-degrees-C lost 38 +/- 5 % activity in the first 4 days, then a further 22 +/- 5 % in 126 days. CIL showed increased stability to low pH although the pH optimum was unchanged. The activation energy of CIL was lower than soluble laccase. Oxidation of 2,6-dimethoxyphenol (DMP) by CIL in a packed-bed system was only 30 +/- 10 % of that in a fluidised bed system. Of the initial activity 10-30 % was retained after oxidation of seven batches of DMP. CIL removed colour from two industrial effluents. Colour was removed from pulp mill bleach plant effluent at 115 colour units per enzyme unit per hour and ...
Animals. Crabs, C. borealis, were obtained from commercial suppliers (Boston, MA) and the Marine Biological Laboratory (Woods Hole, MA). Animals were maintained in aerated artificial seawater at 10-12°C, and were cold-anesthetized by packing in ice for 20-40 min before dissection. The stomach, including the STNS, was removed from the animal, and the rest of the dissection was performed in chilled (∼4°C) physiological saline. Data were obtained from 190 male crabs.. Solutions. C. borealis physiological saline had the following composition (in mm): NaCl, 440; MgCl2, 26; CaCl2, 13; KCl, 11; Trizma base, 10; and maleic acid, 5, pH 7.4-7.6.. Immunocytochemistry. Whole-mount immunocytochemistry was performed using standard techniques for this system (Beltz and Kravitz, 1983; Blitz et al., 1995). Briefly, tissue was fixed for 2-24 hr with either 4% paraformaldehyde or 4% 1-ethyl 3-(3 dimethylaminopropyl)-carbodiimide (EDAC; Sigma, St Louis, MO) in 0.1m sodium phosphate, pH 7.3. Preparations were ...
At the same time, the aircraft industry as a whole was becoming increasingly interested in VTOL aircraft. It was expected that any future European war would start with a nuclear exchange that would destroy most airbases, so aircraft would need to operate from limited airbases, roads or even unprepared fields. Considerable research effort was put into various solutions to securing a second-strike capability. Some of these solutions included rocket-launched aircraft like the zero-length launch concept, while many companies started work on VTOL aircraft as a more appropriate long-term solution.[7] Frost felt the excellent performance of his new engine would be a natural fit for a VTOL aircraft due to its high expected power-to-weight ratio. The problem was how to use the annular thrust to drive the aircraft forward, as well as the problem of fitting the very large engine into a suitable airframe. Frost suggested using a series of ducts and vents to redirect the thrust flowing out of the front of ...

In cellulose, there are several alcohol groups - the two on the ring being secondary alcohols, and the one on the branch being a primary alcohol. I would expect all of these to be oxidised in the presence of any oxidising agent, such as heating under reflux with acidified potassium dichromate - this would give an aldehyde, and then a carboxyl group on the branch, whilst the two on the ring would be oxidised to ketones. However, as you can see in the diagram below (ignoring the sulfonation step which is irrelevant to the question), this is not the case with cellulose.. ...

THE LUNASOL 20 THE NEW BENCHMARK FOR EDC LIGHTS Like my SF A2 thread, this thread is a hymn of praise for a single light, and also like the SF A2 thread, along the way I consider a number of other lights, as well as discuss a number of general and far-reaching topics. As such this thread isnt really a review and doesnt belong in the reviews forum, nor does it have the objectivity and disinterested point of view that usually go along with a review. I love this light. And it shows. Yet

The free carboxyl groups of peptides used for plate coating can be covalently linked via reaction with the water-soluble peptide coupling reagent l-ethyl-3-(3-(dimethylamino)-propy1)carbodiimide (EDC). These peptides can subsequently be linked to amino groups that are attached to the surface of microtiter plate wells. The end result is a population of peptides directly coating the surface of the microtiter plate via peptide bonds.. ...

Medicine X - EDC": 2 day, $400. After the huge success of our regular "Medicine X" course and the continued request from our students; we have created the next evolution of civilian tactical medical training… "Medicine X - EDC (Every Day Carry)"!. This two-day course was developed for those that wanted to learn how to identify and treat life-threatening injuries in a gunfight; but from a civilian concealed carry perspective. If youve taken "Medicine X" before youve learned how to work from your chest rig, plate carrier, body armor, etc. Well, what about when youre not wearing all that kit? How do you carry the contents of an IFAK without the pouch? How do we "run & gun" while in jeans and a T-shirt?. That is exactly what youll learn in this class. Well show students the different options in wearing and using your medical kit as part of your "every day carry" (EDC) gear. No matter if you are a concealed handgun license holder, an undercover LEO, or even working on a low-profile detail; ...

Polyamides comprising substantial amounts of Nylon-11 and/or Nylon-12 units are cross-linked by irradiation in the presence of an unsaturated cross-linking agent, preferably triallyl isocyanurate. The cross-linked products are particularly useful in the form of heat-recoverable shaped articles, e.g. heat-shrinkable tubing.
Much like the EDC staples listed in the previous article, the list below is the more common items but the list can change. Typically the items in the tiers of EDC transfer in that carrying a item in ones pockets might alleviate the need for carrying an additional item in the bag - then again some items stack like flashlights. You can never have too many lights, in my opinion (I have a lot of lights. I may have crawled out of a very deep cave with four guys and two Bic lighters because we came ill prepared and may have vowed to not let that happen again.) Same argument could be made for pocket knives, and probably other items. For the backpack, well start with the above mentioned items and add a few:. -Portable USB charger - Everyone would like their cell phones to last all day long on heavy usage, but sadly thats not the case.

Hydrogels made from the cardiac extracellular matrix (ECM) as two-dimensional (2D) or 3D cell-culture substrates have beneficial biochemical effects on the differentiation of stem cells into cardiomyocytes. The mechanical properties of the substrates that match those of the host tissues have been identified as critical biophysical cues for coaxing the tissue-specific differentiation of stem cells. The objectives of the present study are (1) to fabricate hydrogels comprising pure ventricular ECM (vECM), (2) to make the gels possess mechanical properties similar to those of the decellularized ventricular tissue, and (3) to evaluate the cellular compatibility of the hydrogels. In order to achieve these aims, (1) a simplified protocol was developed to produce vECM solution easily and rapidly, (2) N-(3-Dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDAC) was chosen to crosslink the hydrogels made from the vECM solution to enhance their mechanical properties and stabilize the microstructure of the
Current hydrogels based on chondroitin sulfate (ChS) generally lack the necessary strength and precise mechanical tunability. Addressing these limitations, covalent cross-linking has evolved to produce hydrogels with desirable properties. However, such a methodology always precludes injection and self-healin
Figure 4. CAF-1 binds (H3-H4)2 tetramers and H3-H4 dimers with similar affinities, yet 2-fold different stoichiometries. (A) An overlay of the binding curves for CAF-1 titrated into a H3(L126R, I130R)-H4 double mutant that effectively prevents tetramer formation (gray squares) and a cross-linked (H3-H4)2 tetramer (triangle) with the wild-type H3-H4 curve from Figure 1 (dashed line). The curves are very similar to wild-type and produce dissociation constants of 5.5 nM for the double mutant and 9.0 nM for the cross-linked complex (Table 1). (B) Determination of the stoichiometry of the CAF-1•WT H3-H4 complex by titration of CAF-1 into a constant concentration of labeled H3-H4. Fluorescence change occurs until wild-type H3-H4 is saturated with CAF-1 and the ratio at this inflection point is equal to the number of CAF-1 molecules bound to a single H3-H4 complex. (C) Determination of the stoichiometry of CAF-1/H3(L126R, I130R)-H4 complex. The fluorescence change plateaus similar to that of ...
