A nitrocellulose solution in ether and alcohol. Collodion has a wide range of uses in industry including applications in the manufacture of photographic film, in fibers, in lacquers, and in engraving and lithography. In medicine it is used as a drug solvent and a wound sealant.
Any of several generalized skin disorders characterized by dryness, roughness, and scaliness, due to hypertrophy of the stratum corneum epidermis. Most are genetic, but some are acquired, developing in association with other systemic disease or genetic syndrome.
A chronic, congenital ichthyosis inherited as an autosomal recessive trait. Infants are usually born encased in a collodion membrane which sheds within a few weeks. Scaling is generalized and marked with grayish-brown quadrilateral scales, adherent at their centers and free at the edges. In some cases, scales are so thick that they resemble armored plate.
Transglutaminases catalyze cross-linking of proteins at a GLUTAMINE in one chain with LYSINE in another chain. They include keratinocyte transglutaminase (TGM1 or TGK), tissue transglutaminase (TGM2 or TGC), plasma transglutaminase involved with coagulation (FACTOR XIII and FACTOR XIIIa), hair follicle transglutaminase, and prostate transglutaminase. Although structures differ, they share an active site (YGQCW) and strict CALCIUM dependence.

The immunoglobulin-like modules Cepsilon3 and alpha2 are the minimal units necessary for human IgE-FcepsilonRI interaction. (1/300)

Atopic allergy is a genetically determined immunodisorder that affects almost 20% of the population worldwide. Immediate symptoms of type I allergy are caused by the release of biologic mediators from effector cells induced by IgE-allergen complexes that cross-link the high-affinity receptor for IgE (FcepsilonRI). Chronic disease manifestations result from allergen-specific T-cell activation, a process that is enhanced when allergens are presented via FcepsilonRI-bound IgE. We report the baculovirus expression, as soluble recombinant proteins, of the minimal units required for human IgE and FcepsilonRI interaction: Cepsilon3 represents the third constant domain of the IgE heavy chain, and alpha2 is the membrane-proximal Ig-like module from FcepsilonRIalpha. Native overlay experiments showed binding of human FcepsilonRIalpha to recombinant Cepsilon3 and of natural or recombinant human IgE to recombinant alpha2. Moreover, recombinant Cepsilon3 inhibited binding of natural IgE antibodies to alpha2, and preincubation of human IgE with alpha2 inhibited anti-IgE-triggered histamine release from human basophils. Isolated Cepsilon3 and alpha2 can now be used for the molecular and structural analysis of the IgE-FcepsilonRI interaction, as well as for diagnostic and therapeutic applications.  (+info)

The structure of chromatophores from purple photosynthetic bacteria fused with lipid-impregnated collodion films determined by near-field scanning optical microscopy. (2/300)

Lipid-impregnated collodion (nitrocellulose) films have been frequently used as a fusion substrate in the measurement and analysis of electrogenic activity in biological membranes and proteoliposomes. While the method of fusion of biological membranes or proteoliposomes with such films has found a wide application, little is known about the structures formed after the fusion. Yet, knowledge of this structure is important for the interpretation of the measured electric potential. To characterize structures formed after fusion of membrane vesicles (chromatophores) from the purple bacterium Rhodobacter sphaeroides with lipid-impregnated collodion films, we used near-field scanning optical microscopy. It is shown here that structures formed from chromatophores on the collodion film can be distinguished from the lipid-impregnated background by measuring the fluorescence originating either from endogenous fluorophores of the chromatophores or from fluorescent dyes trapped inside the chromatophores. The structures formed after fusion of chromatophores to the collodion film look like isolated (or sometimes aggregated, depending on the conditions) blisters, with diameters ranging from 0.3 to 10 microm (average approximately 1 microm) and heights from 0.01 to 1 microm (average approximately 0.03 microm). These large sizes indicate that the blisters are formed by the fusion of many chromatophores. Results with dyes trapped inside chromatophores reveal that chromatophores fused with lipid-impregnated films retain a distinct internal water phase.  (+info)

Dot blot assay for detection of antidiacyltrehalose antibodies in tuberculous patients. (3/300)

A simple dot blot test with diacyltrehalose (DAT) as the antigen was developed to detect anti-DAT antibodies in tuberculous patients. To enhance antigen-antibody reaction detection, rabbit serum raised against human immunoglobulins was used prior to incubation with a protein A-colloidal gold complex. With the dot blot system, it was possible to obtain a sensitivity similar to that of enzyme-linked immunosorbent assay (ELISA) and a specificity of 97.14%, versus a specificity of 94.29% by the ELISA. We conclude that this simple and fast assay could be used in places where ELISA equipment is not easy available and that it might also be applicable with other Mycobacterium tuberculosis immunogenic antigens.  (+info)

A simple methodological approach for counting and identifying culturable viruses adsorbed to cellulose nitrate membrane filters. (4/300)

We identified conditions under which Buffalo green monkey cells grew on the surfaces of cellulose nitrate membrane filters in such a way that they covered the entire surface of each filter and penetrated through the pores. When such conditions were used, poliovirus that had previously been adsorbed on the membranes infected the cells and replicated. A plaque assay method and a quantal method (most probable number of cytopathic units) were used to detect and count the viruses adsorbed on the membrane filters. Polioviruses in aqueous suspensions were then concentrated by adsorption to cellulose membrane filters and were subsequently counted without elution, a step which is necessary when the commonly used methods are employed. The pore size of the membrane filter, the sample contents, and the sample volume were optimized for tap water, seawater, and a 0.25 M glycine buffer solution. The numbers of viruses recovered under the optimized conditions were more than 50% greater than the numbers counted by the standard plaque assay. When ceftazidime was added to the assay medium in addition to the antibiotics which are typically used, the method could be used to study natural samples with low and intermediate levels of microbial pollution without decontamination of the samples. This methodological approach also allowed plaque hybridization either directly on cellulose nitrate membranes or on Hybond N+ membranes after the preparations were transferred.  (+info)

Identification of tyrosine phosphatases that dephosphorylate the insulin receptor. A brute force approach based on "substrate-trapping" mutants. (5/300)

Many pharmacologically important receptors, including all cytokine receptors, signal via tyrosine (auto)phosphorylation, followed by resetting to their original state through the action of protein tyrosine phosphatases (PTPs). Establishing the specificity of PTPs for receptor substrates is critical both for understanding how signaling is regulated and for the development of specific PTP inhibitors that act as ligand mimetics. We have set up a systematic approach for finding PTPs that are specific for a receptor and have validated this approach with the insulin receptor kinase. We have tested nearly all known human PTPs (45) in a membrane binding assay, using "substrate-trapping" PTP mutants. These results, combined with secondary dephosphorylation tests, confirm and extend earlier findings that PTP-1b and T-cell PTP are physiological enzymes for the insulin receptor kinase. We demonstrate that this approach can rapidly reduce the number of PTPs that have a particular receptor or other phosphoprotein as their substrate.  (+info)

Distribution and localization of calmodulin-binding proteins in bull spermatozoa. (6/300)

Previous studies from our laboratory have shown that a decrease in the calmodulin binding properties of a few sperm proteins occurs during the capacitation process, an effect associated with a decrease in intracellular calmodulin concentrations. Using biotinylated-calmodulin nitrocellulose overlay assay on protein extracts of subcellular fractions of bull spermatozoa, one of these proteins (p32) is detected in the flagellar-enriched fractions, whereas p30 is found in the fraction enriched with sperm heads. This latter calmodulin binding protein, p30, appears to be associated with the perinuclear theca. None of these binding proteins was solubilized by nonionic detergents. Sodium dodecyl sulfate was effective solubilizing p32, whereas p30 was extracted only in conditions reported to isolate the perinuclear theca. Cellular localization of calmodulin binding proteins was also achieved by incubating spermatozoa fixed on slides with biotinylated calmodulin and revealed in a further step by fluorescein-conjugated streptavidin. Using this procedure, it was found that calmodulin binds to the sub- and postacrosomal areas of the sperm head along with the midpiece in the presence of Ca(2+). Only a sharp band of fluorescence at the subacrosomal area was observed when this procedure was performed in the absence of Ca(2+) in the presence of EGTA. The pattern of cellular calmodulin binding was highly decreased when spermatozoa were incubated under capacitating conditions, in the presence of heparin, in agreement with the published effect of capacitation on calmodulin binding proteins.  (+info)

Inflammatory cytokine production by immunological and foreign body multinucleated giant cells. (7/300)

Multinucleated giant cells (MGC) are a common feature of granulomas. The mechanism of their formation has been studied extensively, but their function has not been completely characterized. A new method for the in vivo production of MGC was developed involving subcutaneous injection of microscopic nitrocellulose particles with adsorbed mycobacterial antigens into the footpads of sensitized BALB/c mice (immune [I]-MGC), or by nitrocellulose administration to non-sensitized mice (foreign body [FB]-MGC). The development of granulomas with a highly enriched MGC population was observed 2 weeks after the nitrocellulose injection. MGC were larger with a greater number of nuclei in I-MGC than in FB-MGC. From days 7-28 after nitrocellulose administration, the production of interleukin-1alpha (IL-1alpha) and tumour necrosis factor-alpha (TNF-alpha) was demonstrated in both MGC types by in situ reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. After 2 months, the MGC had ceased production of IL-1alpha and TNF-alpha, but the expression of transforming growth factor-beta (TGF-beta) was very high, occurring together with extensive fibrosis. These results suggest that MGC are an active source of inflammatory cytokines, which can contribute to the initiation, maintenance and down-regulation of granulomatous inflammation induced by immunological and inert substances.  (+info)

Avian retrovirus DNA internal attachment site requirements for full-site integration in vitro. (8/300)

Concerted integration of retrovirus DNA termini into the host chromosome in vivo requires specific interactions between the cis-acting attachment (att) sites at the viral termini and the viral integrase (IN) in trans. In this study, reconstruction experiments with purified avian myeloblastosis virus (AMV) IN and retrovirus-like donor substrates containing wild-type and mutant termini were performed to map the internal att DNA sequence requirements for concerted integration, here termed full-site integration. The avian retrovirus mutations were modeled after internal att site mutations studied at the in vivo level with human immunodeficiency virus type 1 (HIV-1) and murine leukemia virus (MLV). Systematic overlapping 4-bp deletions starting at nucleotide positions 7, 8, and 9 in the U3 terminus had a decreasing detrimental gradient effect on full-site integration, while more internal 4-bp deletions had little or no effect. This decreasing detrimental gradient effect was measured by the ability of mutant U3 ends to interact with wild-type U3 ends for full-site integration in trans. Modification of the highly conserved C at position 7 on the catalytic strand to either A or T resulted in the same severe decrease in full-site integration as the 4-bp deletion starting at this position. These studies suggest that nucleotide position 7 is crucial for interactions near the active site of IN for integration activity and for communication in trans between ends bound by IN for full-site integration. The ability of AMV IN to interact with internal att sequences to mediate full-site integration in vitro is similar to the internal att site requirements observed with MLV and HIV-1 in vivo and with their preintegration complexes in vitro.  (+info)

Collodion is a flammable, syrupy solution of pyroxylin (a.k.a. nitrocellulose, cellulose nitrate, flash paper, and gun cotton) in ether and alcohol. There are two basic types: flexible; non-flexible. The flexible type is often used as a surgical dressing or to hold dressings in place. When painted on the skin, collodion dries to form a flexible nitrocellulose film. While it is initially colorless, it discolors over time. Non-flexible collodion is often used in theatrical make-up. In 1846 Louis-Nicolas Ménard and Florès Domonte discovered that cellulose nitrate could be dissolved in ether. They devised a mixture of ether (ethoxyethane) as the solvent and ethanol as a diluent that rendered cellulose nitrate into a clear gelatinous liquid. Collodion was first used medically as a dressing in 1847 by the Boston physician John Parker Maynard. The solution was dubbed collodion (from the Greek κολλώδης (kollodis), gluey) by Dr. A.A. Gould of Boston, Massachusetts. In 1851, Frederick ...
The collodion process produced a negative image on a transparent support (glass). This was an improvement over the calotype process, discovered by Henry Fox Talbot, which relied on paper negatives, and the daguerreotype, which produced a one-of-a-kind positive image and could not be replicated. The collodion process, thus combined desirable qualities of the calotype process (enabling the photographer to make a theoretically unlimited number of prints from a single negative) and the daguerreotype (creating a sharpness and clarity that could not be achieved with paper negatives). Collodion printing was typically done on albumen paper. As collodion is a sticky and transparent medium, and can be soaked in a solution of silver nitrate while wet, it is ideal for coating stable surfaces such as glass or metal for photography. When a metal plate is coated with collodion, charged with silver nitrate, exposed, and developed, it produces a direct positive image, although backwards on the plate due to ...
1. In three previous publications it had been shown that electrolytes influence the rate of diffusion of pure water through a collodion membrane into a solution in three different ways, which can be understood on the assumption of an electrification of the water or the watery phase at the boundary of the membrane; namely,. (a) While the watery phase in contact with collodion is generally positively electrified, it happens that, when the membrane has received a treatment with a protein, the presence of hydrogen ions and of simple cations with a valency of three or above (beyond a certain concentration) causes the watery phase of the double layer at the boundary of membrane and solution to be negatively charged.. (b) When pure water is separated from a solution by a collodion membrane, the initial rate of diffusion of water into a solution is accelerated by the ion with the opposite sign of charge and retarded by the ion with the same sign of charge as that of the water, both effects increasing ...

Welcome to The Silver Sunbeam - online home of Andy Martins forays into, and 21st century resurrection of, the Victorian era Wet Collodion (wetplate) photographic process in the tintype studio and across the North of England since 2010.. The images you see here are taken directly on metal and glass plates using a technique which dates back to 1851, invented by Englishman Frederick Scott Archer. On this site is a mix of studio based tintypes and ambrotypes of people Ive known a long time, some Ive only just met, a selection of scenes of Sunderland, Tanfield Railway, Beamish Museum and across the wider North East.. The wet collodion process involves coating a metal or glass plate with a collodion solution before placing it into a bath of silver nitrate. Once sensitised by the silver, the plate is loaded into the camera and the exposure made, ranging from a second up to a minute (sometimes more), depending on the lighting conditions.. Then, the plate is returned to the darkroom and developed, ...

Proteoglycan (PG) and glycosaminoglycan (GAG) samples corresponding to a minimum of 10 ng of uronic acid were reliably quantified as precipitates with the cationic dye Safranin O, collected by vacuum-aided filtration onto a cellulose acetate/nitrate membrane in a standard 96-well dot assay apparatus. The reflectances of the precipitation dots were measured by automatic densitometric scanning of the membrane sheets. Standard GAGs produced reflectance values which were related to the number of anionic groups per unit disaccharide; hyaluronate and keratan sulfate gave lower values while heparin yielded values higher than those of chondroitin sulfates. The presence of 8 m urea, 1% Triton X-100, 30% sucrose, 0.02% NaN3, or mixtures of proteinase inhibitors and various buffers did not markedly influence the reflectances, while 4 m guanidinium chloride and 3 m CsCl reduced the sensitivity of the assay to 30-50 ng. Samples containing sodium dodecyl sulfate (SDS) were not applicable because SDS ...
In 1851, Frederick Scott Archer invented a new photographic process to replace one-of-a-kind daguerreotypes on metal that were popular for portraits and multiple but imprecise calotypes made from paper negatives. The new process produced a clear negative on transparent glass that could be used to print multiple prints on paper. As its name implies,wet-plate collodion exposure and development of the negative had to be done within a ten-minute time frame while the light sensitive chemicals were wet, requiring photographers to bring portable darkrooms into the field. Although the process was capable of rendering fine detail within the shadows, the chemicals were sensitive only to blue light, making it impossible to render cloud-filled skies without exposing a separate negative only for the clouds. Because practical techniques for enlarging were not yet available, the glass negatives had to be the size of the finished print.. To achieve a large, or mammoth, print, a photographer required a glass ...
After some very disappointing experience, I adopted the following treatment: Immediately, on the discovery of a case of cerebral protrusion, I paint the protruding part with collodion; I order the nurse to do this three times a day. The collodion is carried entirely over the tumor, and down upon the scalp one-half an inch below the lower line of the protrusion. In twenty-four hours the hardened collodion has made a light, strong, cartilaginous-like cap, which fits loosely, yet perfectly, the protruding cerebral substance. From the moment it is applied the child is protected from all ordinary chances of head injury. Its head can be washed, its hair brushed, and it can be laid upon its pillow with but little chance of injuring the diseased parts. If the tumor protrudes much, it raises the plate, and yet is still covered by it. At the expiration of a week or so, I only paint the upper half of the plate and scalp, having the lower half free to permit of spraying or syringing with carbolized water. ...

MY instructions hitherto have been limited strictly to the chemical and mechanical manipulations that occur in that department of photography denominated the Wet Collodion Process. This process will ever remain the predominant mode of conducting photographic operations in the room; it is preferred, too, by many tourists in the field. The inconvenience, however, of dragging along over mountain and valley, or of stowing away on steamer or on the cars, a complete miniature operating gallery, has suggested the idea of superseding all this trouble by the discovery of a dry process. Several processes have been discovered which are more or less successful, and all very practical; but it must be confessed that the same degree of sensitiveness in the dry process has not yet been attained as in the wet process--instantaneous pictures are the result only of the latter. It appears natural for us to expect such a result; chemical combinations and reductions are effected most easily when the mole-cubes of ...

including progressive yellowing (to dark brown), formation of bubbles or foam, embrittlement and shrinkage of the film, and degradation into a powdery or foamy mass. These changes are accompanied by foul odours from nitrogen oxide gases. The same progression of decay can be expected for any cellulose nitrate object, but at a much slower rate for three-dimensional objects because they are made from less highly nitrated material than is film.. These changes are accompanied by progressive decreases in auto-ignition temperature, the lowest temperature at which an object will self-ignite without a direct heat source (spontaneous combustion). Fresh, undegraded cellulose nitrate auto-ignites at 150°C (paper ignites at 315°C to 370°C). The powdery or foamy mass of cellulose nitrate in the last stages of decomposition can auto-ignite at temperatures as low as 50°C. This temperature can easily be reached near light bulbs, radiators, and other heating equipment, or in unventilated buildings and attics ...

The wet plate collodion process has many applications. The most historically popular and prevalent has been the tintype. A tintype is an image made on a blackened sheet of metal. Historically, the metal was Japaned by baking asphalt onto a metal plate. Today, the material of choice is trophy plate: painted aluminum used for engraving on trophies. Wet plate collodion is a process where a plate of either glass or metal has a salted collodion based emulsion poured over it. The plate is gently put into a silver nitrate solution to make it light sensitive. This is then loaded into a modified plate holder, exposed in camera and developed in the darkroom. The reason it is called wet plate is the plate is exposed while wet. As the old whites guys said We hold these truths to be self-evident. ...
Ian Ruhter had been working as a successful commercial and sports photographer when he first discovered the wet plate collodion process. The nineteenth century photographic process involves pouring a liquid mixture of iodides, bromides, and a solution called collodion over a glass or aluminum plate. The plate is then bathed in silver nitrate, making it light-sensitive. The plate must then be quickly exposed and developed in just a few minutes, before the collodion dries and loses sensitivity. The process is expensive, laborious, and extremely unpredictable as temperature and moisture affect the chemicals greatly and can entirely alter the developing process, ruining a wet plate. But the results of this labor intensive process are undeniable-- a completely unique and incredibly detailed image, with rich layers of silver suspended in emulsion producing a three dimensional effect. Because the process is produced and controlled entirely by hand, each plate is inherently unique, with the chemicals ...

Hi! I have questions about glycoprotein staining. I have partial purified some protein with con-A sepharose. When I electrophoresed the partial purified eluate, several major and minor bands ranged from 10 to 150 kD were appeared on silver stained gel. But I didnt get any signal from DIG detection on nitrocellulose membrane under about 50 kD. Of course, standard glycoprotein, fetuin was stained well. So, I am wondering whether all of the proteins eluted from lectin chromatography were glycoprotein or a part of the protein was non-glycoprotein. My second question is what product for glycoprotein staining is more sensitive and specific. Any idea will be helpful to me. Thanks. Best regards.

Legionella pneumophila is a facultative intracellular bacterium which replicates within amoebae and macrophages by a similar mechanism. Intracellular replication within both protozoa and mammalian cells requires the bacterial icm/dot genes, encoding a conjugation apparatus related to type IV secretion systems (T4SSs). The inositol carbohydrate moiety of phosphoinositides (PIs) is phosphorylated at positions 3, 4, and/or 5 by specific kinases or dephosphorylated by phosphatases, respectively. Phagocytosis of L. pneumophila by Dictyostelium was determined by a gentamicin protection assay and by flow cytometry. Wild-type L. pneumophila (but not ΔicmT) replicated more efficiently in ΔPI3K1/2 or in wild-type Dictyostelium treated with PI3K inhibitors. To investigate whether Icm/Dot secreted proteins bind in vitro to PIs immobilized on nitrocellulose membranes, the authors performed a lipid protein overlay assay using glutathione S-transferase fusion proteins and an anti-glutathione S-transferase antibody.
A biomarker for RA was identified in the synovial fluid of patients with RA using a modified strategy previously used to identify cancer biomarkers. An Agilent immunodepletion column was used to remove six abundant serum proteins (albumin, antitrypsin, haptoglobin, IgA, IgG, and transferrin) then the depleted synovial fluid was fractionated using a Beckman ProteomeLab PF2D Protein Fractionation System. Proteins were fractionated in the first dimension by chromatofocussing and in the second dimension by reverse phase High Performance Liquid Chromatography. This protein fractionation strategy increased the chance of identifying the lower abundance proteins by separating them from the higher abundance proteins, which could mask their presence. The second dimension fractions were used to construct protein arrays on nitrocellulose membranes, which were used to test for the presence of autoantigens by analysing differential reactivity of RA and control sera. Only sera obtained from RA patients is ...

1. This paper gives measurements of the influence of various electrolytes on the cataphoretic P.D. of particles of collodion coated with gelatin, of particles of casein, and of particles of boiled egg albumin in water at different pH. The influence of the same electrolyte was about the same in all three proteins.. 2. It was found that the salts can be divided into two groups according to their effect on the P.D. at the isoelectric point. The salts of the first group including salts of the type of NaCl, CaCl2, and Na2SO4 affect the P.D. of proteins at the isoelectric point but little; the second group includes salts with a trivalent or tetravalent ion such as LaCl3 or Na4Fe(CN)6. These latter salts produce a high P.D. on the isoelectric particles, LaCl3 making them positively and Na4Fe(CN)6 making them negatively charged. This difference in the action of the two groups of salts agrees with the observations on the effect of the same salts on the anomalous osmosis through collodion membranes coated ...

Two types of composite imprinted membranes, i.e., composite membrane comprised of D-Phe imprinted beads and D-Phe imprinted membrane or DCM and composite membrane comprised of L-Phe imprinted beads and L-Phe imprinted membranes or LCM, were synthesized by phase inversion technique after a uniform dispersion of beads within the polymeric solutions using simple physico-mechanical process. The assemblies of the prepared DCM, LCM and control membranes were employed in ultrafiltration for chiral separation of D, L-Phenylalanine racemate solution. DCM and LCM showed an improved adsorption capacity (0.334 mg g-1 and 0.365 mg g-1 respectively), and adsorption selectivity (2.72 and 2.98 respectively). However, the percent rejection of the template and counter enantiomer were lower than that of control membranes. Compared to control membrane, the DCM and LCM showed inverse permselectivity. These composite membranes having better adsorption and separation ability for Phenylalanine racemate solution will be ...
The primary objective of this project was to prepare and characterize a hydrogen permselective palladium-ceramic composite membrane for high temperature gas separations and catalytic membrane reactors. Electroless plating method was used to deposit a thin palladium film on microporous ceramic substrate. The objective of this paper is to discuss the preparation and characterization of a thin-film palladium-ceramic composite membrane for selective separation of hydrogen at elevated temperatures and pressures. In this paper, we also present a model to describe the hydrogen transport through the palladium-ceramic composite membrane in a cocurrent flow configuration.

AU - Agrawal, Devendra K.. PY - 1992. Y1 - 1992. N2 - A group of proteins binding to inositol 1,4,5-trisphosphate (IP3) has been identified in rat liver microsomes by a nitrocellulose blot-overlay technique. Proteins were resolved by SDS-PAGE, blotted on nitrocellulose and incubated with [32P]IP3 followed by autoradiography. Approximately eight IP3-binding polypeptides ranging Mr 23-50 kDA were present exclusively in microsomes; these were absent from plasma membrane and mitochondrial fractions. Binding of [32P]IP3 to these proteins was displaceable to a great extent by 5 μM unlabeled IP3 but not by 10 μM IP1, IP2, IP4, ATP, or GTPγS. These results suggest that liver microsomes contain multiple forms of IP3-binding proteins that can be detected by this new method.. AB - A group of proteins binding to inositol ...
Duncan is a portrait photographer and photographic historian using the historic wet plate collodion process. Invented in 1851, the wet plate process creates unique, handmade photographs on glass (Ambrotype) or Aluminium (Tintype). The process involves coating a glass or aluminium plate with a liquid collodion emulsion, sensitizing the plate in a bath of silver nitrate, exposing the plate in an antique large format brass and wood camera, and developing the plate inside a small mobile darkroom. As the plate needs to be wet during exposure and development, the whole process must take less than ten minutes. After drying, the plate is coated using a traditional organic lavender and sandarac varnish. The wet plate process is a truly handmade and original method of creating portraits, and in many ways stands as an antithesis of modern digital photography. The final work of art is completely unique and is not reproducible. When created properly the images are archival, and will last for more than 100 ...
Toronto. After 1851 when Frederick Scott Archer invented the first practical wet-plate process, you could tell a photographer from his blackened finger-tips. This situation came about by the practitioners need to sensitize his glass plate with a silver nitrate solution.. First, a collodion emulsion was carefully poured over the clean glass plate. This viscous emulsion stuck to the glass and offered a base for the silver halide bath (the silver nitrate and collodion - the viscous emulsion - form light sensitive silver halides). The whole gooey mess had to be moved to the camera, the camera to the scene for the shot, and back to the darkroom to develop the negative, all before the sensitized emulsion dried. Even in bright daylight a tripod was a necessity for sharp images.. And the bottle shown here was an essential ingredient to create a media sensitive to a brief daylight exposure in the camera, suitably mounted on a tripod, of course…. ...
Ambrotypes look… well, they look just like that one of me on this page. I did a bit of retouching on my face and uniform, but all the wonderful frayed bits? Thats just the nature of the process. And if youve ever wondered why nobody in the late 19th century ever seemed to smile, heres why: The exposure on an ambrotype is around 60 seconds. You can blink. It wont matter. It wont show up in the image. Try holding a smile for 60 seconds, though, without having it look like a creepy rictus.. As part of my photo session with Stephen I got to go through the whole process with him. My friend Suzanne and I polished the glass plates. We watched him coat them with a thin layer of collodion before dipping them in a solution of silver nitrate. After he took several exposures of me, we watched him develop the images in his darkroom.. The wet plate collodion process fixes the light parts of the scene. To see the full image you have to hold the plate before a dark background. As the picture is developed ...

On the Monday night I hardly managed to get any sleep somehow - I shall blame it on the huge list of things-to-do on my list!. After getting up at silly-O-clock (6:00) I check on my collodion mixture - and it looks good! I pour a little on the ends of some narrow-cut plates so I can leave those in the silver bath jar overnight.. no images were found. My mum and I went on an epic shopping round through the area, visiting 6 second-hand shops to find things I still needed for this project. Remember - I may be sponsored but I am on a budget! Lets make that buck go further! This time, I found a good glass bowl, wisk, plate fryer aka BBQ utensil, coffee filter, small bottles with screwcap (these are actually baby bottles and they are a fantastic size! Dont mix them up with the one for the baby though…) and a drying rack.. So having gotten these items, I decant the collodion mixture into 3 of these 300 ml bottles (2 full, 1 to about 1/3rd). I mixed up the egg whites and ammonium iodine to create ...
A lot of my focus has been on Cadmium free Collodion's, so I wanted to show, as best I can, the difference (or same-ness) of a couple of different formulas. Ive done many multiple plates using these formulas, so Ive tried to choose representative samples of each. They are all from my standard shot, using the same silver bath, developer, fixer and varnish. The only variation is exposure time for the UVP #3 All Lithium formula.Collodions shown:Lea Formula #1 - this is a classic Ammonium Iodide, Cadmium Bromide Formula that is similar to Quinns Quick Clear. UVP Formula #1 - this is an Ammonium Iodide, Lithium Bromide Formula that behaves similarly to the Lea#1 UVP Formula #3 - this is a Lithium Iodide, Lithium Bromide Formula that is 1 or more stops faster that the other two standard speed formulas.The Lea 1 and UVP 1 were both exposed for 7 seconds while the UVP 3 was between 2 and 3 seconds.They are all very close, but I prefer the UVP #1. The UVP #3 has less detail in the blacks, so opting

Back in March 2018 Lorraine Finch, a photograph conservator, gave the archive team some valuable training on identifying different photographic processes and how to care for the different types of photographic material. We were aware that among the various photographic formats held in the Jesuits in Britain Archives there was a collection of glass plate negatives.. Before cellulose nitrate film was invented in 1903, photographic emulsions were made on glass supports, more typically known as glass plate negatives, and this enabled amateur as well as professional photography to flourish. There are two separate glass plate negative photographic methods which both consist of a light sensitive emulsion fixed to the glass plate base with a binder. In 1851, at almost the same time, Frederick Scott Archer (1813-1857) and Jean-Baptiste Gustave Le Gray (1820-1884) produced the first collodion wet plate negatives. Wet plate negatives were produced by spreading a glass plate with collodion, bathed in silver ...
Polymer chemistry started by studying the long fibers in plants. The work of Henri Braconnot in 1777 and the work of Christian Schönbein in 1846 led to the discovery of nitrocellulose. Nitrocellulose treated with camphor makes celluloid. Chemists dissolve celluloid in ether or acetone to make collodion. Doctors have used collodion as a wound dressing since the U.S. Civil War. Cellulose acetate was first prepared in 1865. In 1834, Friedrich Ludersdorf and Nathaniel Hayward independently discovered that adding sulfur to raw natural rubber (polyisoprene) helped prevent the material from becoming sticky. In 1844 Charles Goodyear received a U.S. patent for vulcanizing rubber with sulfur and heat. Thomas Hancock had received a patent for the same process in the UK the year before. In 1884, Hilaire de Chardonnet started the first artificial fiber factory based on regenerated cellulose, or viscose rayon, as a substitute for silk, but it was very flammable.[4] In 1907 Leo Baekeland invented the first ...

Dressings. These may be either dry or wet.. Dry dressings consist of gauze and bandage or of cotton and collodion (the cocoon dressing.). The most convenient form in which sterile gauze can be obtained is in small squares in individual envelopes. Large packages are contaminated with the first opening and are inconvenient.. The cocoon dressing is occlusive and should never be applied over an infected area. It is applicable to sensitive areas for protection, and to operated areas not liable to infection.. Protective varnishes, such as collodion, compound tincture of benzoin, or pure ichthyol, are useful where little protection is indicated.. Wet dressings. Two distinct therapeutic actions may be derived from the wet compress, depending upon whether or not an impervious covering is employed. These actions are antiphlogistic and hyperemic, and these in turn may be either antiseptic or astringent. The wet dressing, without a covering, is cleansing and heat reducing, because of evaporation. There ...

TY - JOUR. T1 - Preparation of Pt/zeolite-Nafion composite membranes for self-humidifying polymer electrolyte fuel cells. AU - Son, Dong Hoon. AU - Sharma, Raj Kishore. AU - Shul, Yong Gun. AU - Kim, Hansung. PY - 2007/3/20. Y1 - 2007/3/20. N2 - A novel Pt/zeolite-Nafion (PZN) polymer electrolyte composite membrane is fabricated for self-humidifying polymer electrolyte membrane fuel cells (PEMFCs). A uniform dispersion of Pt nanoparticles with an average size of 3 nm is achieved by ion-exchange of the zeolite HY. The Pt nanoparticles embedded in the membrane provide the catalytic sites for water generation, whereas the zeolite HY-supported Pt particles absorbs water and make it available for humidification during cell operation at elevated temperature. Compared with the performance of ordinary membranes, the performance of cells with PZN membranes is improved significantly under dry conditions. With dry H2 and O2 at 50 °C, the PZN membrane with 0.65 wt.% of Pt/zeolite (0.03 mg Pt cm-2) gives ...
Carbon nanotubes are attractive approach for designing of new membranes for advanced molecular separation because of their unique transport properties and ability to mimic biological protein channels. In this work the synthetic approach for fabrication of carbon nanotubes (CNTs) composite membranes is presented. The method is based on growth of multi walled carbon nanotubes (MWCNT) using chemical vapour deposition (CVD) on the template of nanoporous alumina (PA) membranes. The influence of experimental conditions including carbon precursor, temperature, deposition time, and PA template on CNT growth process and quality of fabricated membranes was investigated. The synthesis of CNT/PA composites with controllable nanotube dimensions such as diameters (30-150 nm), and thickness (5-100 µm), was demonstrated. The chemical composition and morphological characteristics of fabricated CNT/PA composite membranes were investigated by various characterisation techniques including scanning electron microscopy (SEM

Chitosan/coconut (CTS/coconut) composite membranes were successfully prepared by the cross-linking reaction with glutaraldehyde and they were applied in eliminating heavy metals from aqueous solutions. The cross-linked membranes were obtained at the ratios of 1/1, 1/1.5 and 1/2 and the coconut fiber was chemically treated by NaOCl/NaOH. The best ratio of CTS/coconut fiber is found to be 1/1.5 which has a relatively high stability with the degree of swelling (DS) and solvent content (SC) of membrane to be 13.33% and 69.88%, respectively. The results also indicate that the CTS membranes showed preferential separation of heavy metals for blend CTS/coconut membranes.

24-25); other test specimens included portions of dispensable collodion negatives in various conditions. The samples were analyzed in an attempt to determine the role of glass deterioration in the degradation of 19th-century negatives.. Surface deposits from the secondry-support glass plates were rinsed with distilled water into sample cups for analysis by x-ray fluorescence. A blank was similarly prepared but by rinsing newly made window glass into the sample cups. With titanium being used as the target, the presence of silicon in the surface deposit was confirmed. No silicon was detected in the blank. There is no obvious source of silicon other than the glass itself, therefore it appears that the glass is chemically unstable and plays a role in the deterioration of the negative.. An attempt was made to quantify the silicon present in the surface deposits of a deteriorated secondary support (one sample) and in the varnish and binder layers of 19th-century plates in both good condition (one ...
Background: Plastic baby are those babies who looks like a rubber doll and sheds skin like that of reptile scales at birth. It is also known as the collodion baby which is a descriptive term for the infant, born encased in a tight shiny membrane that resembles plastic wrap1. Method: This article explains the incidence, causes, pathogenesis, signs and symptoms and various recent treatment modalities for plastic baby. Result: Unfortunately, most of people are unaware that this types baby can be born and till now only 2 cases are report in India. Conclusion: Recent advancement in the understanding of the causative genetic defects making DNA-based prenatal diagnosis is now possible, using chorionic villus or amniotic fluid sampling procedures early in pregnancy, with a lower risk to fetal health and with a reduced burden on the parents.
That, surely, is a considerable exaggeration, for Eastman led a notably active life and had no trouble making his way in the world. Although he left school after the seventh grade to get a job at three dollars a week, he was an avid reader, and new things always interested him. By the time he was 15, he was earning six dollars a week, a very good wage for an adolescent.. At 21 he had a job at the Rochester Savings Bank that paid him $1,000 a year, a middle-class income. In 1877 he was prosperous enough to plan a trip to Santo Domingo, and he bought a camera to take along, paying $49.58, according to his meticulously kept personal accounts. He got more than just a camera. Indeed, he also got, according to a letter he wrote in 1891, a tripod, plus plates, paper, boxes for storing negatives, and a tent that he could set up as a darkroom, also the furnishings of a small chemistry laboratory-nitrate of silver, acetate soda, chlorides of gold, sodium, and iron, collodion, varnish, alcohol....
