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 clear, colorless, viscous solution that is used in medicine and photography. Medically, collodion is often used as a temporary protective dressing for wounds, burns, or skin abrasions. When applied to the skin, it dries to form a flexible, waterproof film that helps to prevent infection and promote healing. Collodion is typically made from a mixture of nitrocellulose, alcohol, and ether.

In photography, collodion was historically used as a medium for wet plate photography, which was popular in the mid-19th century. The photographer would coat a glass plate with a thin layer of collodion, then sensitize it with silver salts before exposing and developing the image while the collodion was still wet. This process required the photographer to carry a portable darkroom and develop the plates immediately after exposure. Despite its challenges, the wet plate collodion process was able to produce highly detailed images, making it a popular technique for portrait photography during its time.

Ichthyosis is a group of skin disorders that are characterized by dry, thickened, scaly skin. The name "ichthyosis" comes from the Greek word "ichthys," which means fish, as the skin can have a fish-like scale appearance. These conditions can be inherited or acquired and vary in severity.

The medical definition of ichthyosis is a heterogeneous group of genetic keratinization disorders that result in dry, thickened, and scaly skin. The condition may affect any part of the body, but it most commonly appears on the extremities, scalp, and trunk. Ichthyosis can also have associated symptoms such as redness, itching, and blistering.

The severity of ichthyosis can range from mild to severe, and some forms of the condition may be life-threatening in infancy. The exact symptoms and their severity depend on the specific type of ichthyosis a person has. Treatment for ichthyosis typically involves moisturizing the skin, avoiding irritants, and using medications to help control scaling and inflammation.

Lamellar Ichthyosis is a rare, inherited genetic skin disorder characterized by widespread, persistent scaling of the skin. It is caused by mutations in genes responsible for maintaining the barrier function and hydration of the skin. The condition is present from birth and can vary in severity.

In lamellar ichthyosis, the skin cells do not shed properly and instead accumulate in plates or scales that cover the entire body. These scales are large, dark brown or gray, and have a cracked appearance, resembling fish scales. The scales may be present at birth (congenital) or develop within the first few weeks of life.

The skin is also prone to redness, irritation, and infection due to the impaired barrier function. Other symptoms can include overheating, dehydration, and difficulty with sweating. The condition may improve in warmer, more humid environments.

Treatment for lamellar ichthyosis is aimed at managing symptoms and preventing complications. This may include topical creams and ointments to moisturize the skin, medications to reduce inflammation and infection, and avoiding environmental triggers that can worsen symptoms. In some cases, oral retinoids may be prescribed to help regulate skin cell growth and shedding.

Transglutaminases are a family of enzymes that catalyze the post-translational modification of proteins by forming isopeptide bonds between the carboxamide group of peptide-bound glutamine residues and the ε-amino group of lysine residues. This process is known as transamidation or cross-linking. Transglutaminases play important roles in various biological processes, including cell signaling, differentiation, apoptosis, and tissue repair. There are several types of transglutaminases, such as tissue transglutaminase (TG2), factor XIII, and blood coagulation factor XIIIA. Abnormal activity or expression of these enzymes has been implicated in various diseases, such as celiac disease, neurodegenerative disorders, and cancer.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

Micropore filters are medical devices used to filter or sterilize fluids and gases. They are made of materials like cellulose, mixed cellulose ester, or polyvinylidene fluoride with precise pore sizes, typically ranging from 0.1 to 10 micrometers in diameter. These filters are used to remove bacteria, fungi, and other particles from solutions in laboratory and medical settings, such as during the preparation of injectable drugs, tissue culture media, or sterile fluids for medical procedures. They come in various forms, including syringe filters, vacuum filters, and bottle-top filters, and are often used with the assistance of a vacuum or positive pressure to force the fluid through the filter material.

A bandage is a medical dressing or covering applied to a wound, injury, or sore with the intention of promoting healing or preventing infection. Bandages can be made of a variety of materials such as gauze, cotton, elastic, or adhesive tape and come in different sizes and shapes to accommodate various body parts. They can also have additional features like fasteners, non-slip surfaces, or transparent windows for monitoring the condition of the wound.

Bandages serve several purposes, including:

1. Absorbing drainage or exudate from the wound
2. Protecting the wound from external contaminants and bacteria
3. Securing other medical devices such as catheters or splints in place
4. Reducing swelling or promoting immobilization of the affected area
5. Providing compression to control bleeding or prevent fluid accumulation
6. Relieving pain by reducing pressure on sensitive nerves or structures.

Proper application and care of bandages are essential for effective wound healing and prevention of complications such as infection or delayed recovery.
