Connectin, an elastic protein from myofibrils. (1/1192)

The elastic protein isolated from myofibrils of chicken skeletal muscle was compared with extracellular non-collagenous reticulin prepared from chicken liver and skeletal muscle. The amino acid compositions of these proteins were similar except that their contents of Phe, Leu, Cys/2, and Hyp were different. The impregnations of the elastic protein and reticulin with silver were also different. The reticulin was not at all elastic. It also differed from reticulin in solubility and antigenicity. It is proposed to call the intracellular elastic protein connectin. (+info)

Adhesion of adhesive resin to dental precious metal alloys. Part I. New precious metal alloys with base metals for resin bonding. (2/1192)

New dental precious metal alloys for resin bonding without alloy surface modification were developed by adding base metals (In, Zn, or Sn). Before this, binary alloys of Au, Ag, Cu, or Pd containing In, Zn, or Sn were studied for water durability and bonding strength with 4-META resin. The adhesion ability of the binary alloys was improved by adding In equivalent to 15% of Au content, Zn equivalent to 20% of Ag content, and In, Zn, or Sn equivalent to 5% of Cu content. There was no addition effect of the base metals on Pd, however 15% of In addition improved adhesion with Pd-based alloys containing equi-atomic % of Cu and Pd. The alloy surfaces were analyzed by XPS and showed that oxides such as In2O3, ZnO, or SnO play an important role in improving the adhesive ability of the alloys. (+info)

Perineuronal nets of proteoglycans in the adult mouse brain, with special reference to their reactions to Gomori's ammoniacal silver and Ehrlich's methylene blue. (3/1192)

As our previous studies have indicated, many subsets of neurons in the vertebrate brain possess a sulfated proteoglycan surface coat which reacts to cationic iron colloid and aldehyde fuchsin. The present study demonstrated that this surface coat is supravitally stained with Ehrlich's methylene blue, and doubly with this blue and aldehyde fuchsin, a finding suggesting its being identical to Cajal's superficial reticulum (red superficial) and to Golgi's reticular coating (revetement reticulare). The perineuronal surface coat was further stained with Gomori's ammoniacal silver, and doubly with this silver and cationic iron colloid. These neurons with such a proteoglycan surface coat usually expressed cell surface glycoproteins which were labeled with lectin Wisteria floribunda agglutinin. Hyaluronidase digestion did not interfere with this lectin labeling of the glycoproteins, methylene blue and Gomori's ammoniacal silver staining of the surface coat, while it erased the cationic iron colloid and aldehyde fuchsin staining of the surface coat. These findings suggest that the perineuronal proteoglycan surface coat is associated with some additional molecules which are resistant to hyaluronidase digestion and stainable with methylene blue and Gomori's ammoniacal silver. The possibility is suggested that these molecules might represent "ligand proteoglycans" connecting the perineuronal proteoglycans and cell surface glycoproteins. (+info)

Modified hemoglobins produce venular interendothelial gaps and albumin leakage in the rat mesentery. (4/1192)

Cross-linked hemoglobin (alphaalpha-Hb) and polyethylene glycol (PEG)-conjugated Hb have both been considered as possible "blood substitutes." Previously, we showed that PEG-Hb extravasates rapidly in the intestinal mucosa and causes transient epithelial sloughing, resulting in temporary opening of the intestinal epithelial barrier. In the present study, the rat mesenteric preparation was used to quantify the effects of the two Hbs on microvascular leakage to albumin and to investigate possible changes in the integrity of the interendothelial cell junctions and the endothelial actin cytoskeleton. In anesthetized Sprague-Dawley rats, the microvasculature of a mesenteric window was perfused with HEPES-buffered saline (HBS) containing 0.5 mg/ml BSA and 2 mg/ml alphaalpha-Hb (n = 16) or PEG-Hb (n = 5) for 2 or 10 min. Controls (n = 4) just received HBS-BSA. In some experiments (n = 9 for alphaalpha-Hb; n = 5 for PEG-Hb), the perfusate was then replaced by FITC-albumin in HBS-BSA for the next 3 min. The vasculature was then perfusion fixed, stained for filamentous actin and for mast cells, and viewed microscopically. In the remaining experiments, the mesenteric microvasculature was stained with silver nitrate to determine the number of endothelial junctional gaps per length of venules. Both Hbs increased the number and area of leaks per micrometer of venular length compared with control, but alphaalpha-Hb increased to a greater extent than PEG-Hb. Formation of leaks was accompanied by changes in the endothelial actin cytoskeleton and by an increased number of endothelial gaps. Mast cell degranulation was significantly greater (P < 0.05) in Hb-treated preparations compared with controls, but there was no direct correlation between sites of degranulation and albumin leakage. These Hbs appear to induce venular leakage in the mesentery by mechanisms similar to those previously observed after treatment with histamine or nitric oxide synthase inhibitors. (+info)

Silver-based crystalline nanoparticles, microbially fabricated. (5/1192)

One mechanism of silver resistance in microorganisms is accumulation of the metal ions in the cell. Here, we report on the phenomenon of biosynthesis of silver-based single crystals with well-defined compositions and shapes, such as equilateral triangles and hexagons, in Pseudomonas stutzeri AG259. The crystals were up to 200 nm in size and were often located at the cell poles. Transmission electron microscopy, quantitative energy-dispersive x-ray analysis, and electron diffraction established that the crystals comprise at least three different types, found both in whole cells and thin sections. These Ag-containing crystals are embedded in the organic matrix of the bacteria. Their possible potential as organic-metal composites in thin film and surface coating technology is discussed.

Activities of a nitrofurazone-containing urinary catheter and a silver hydrogel catheter against multidrug-resistant bacteria characteristic of catheter-associated urinary tract infection. (6/1192)

The in vitro inhibitory activity of a nitrofurazone-coated urinary catheter (NFC) against 86 recently obtained susceptible and multidrug-resistant (MDR) clinical isolates of Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, Staphylococcus aureus, coagulase-negative staphylococci, and Enterococcus faecium, which are species implicated in catheter-associated urinary tract infection and which traditionally have been susceptible to nitrofuran derivatives, was determined using an agar diffusion assay. In a subset of these strains, the activity of the NFC was compared with that of a silver hydrogel urinary catheter (SHC), and the durability of each catheter's inhibitory activity was assessed during serial daily transfers of catheter segments to fresh culture plates. Except for vancomycin-resistant E. faecium, the NFC was active against all isolates tested and showed comparable inhibition zones with susceptible and MDR strains of each species. In contrast, the SHC inhibited only certain staphylococci (P < 0.01 versus the NFC), and among these strains, the SHC produced smaller inhibition zones than did the NFC (P < 0.01). Inhibition was evident for up to 5 days with the NFC, but for only 1 day (if at all) with the SHC (P < 0.01). These data document that, for most genera which traditionally have been susceptible to nitrofuran derivatives, the NFC remains active against contemporary MDR isolates. They also demonstrate that the in vitro antibacterial activity of the NFC is markedly superior to that of the SHC in several respects. Thus, the NFC shows promise for clinical use in the current era of MDR bacteria. (+info)

Four years of experience with silver-copper ionization for control of legionella in a german university hospital hot water plumbing system. (7/1192)

Silver-copper ionization was used for controlling Legionella distribution in a German university hospital hot water plumbing system for 4 years. In the beginning, silver concentrations were not allowed to exceed 10 microg/L because of drinking water regulation limits in Germany. Water samples were monitored for Legionella counts, temperature, and silver and copper concentrations. A significant (P<.001) 3.8-log reduction of Legionella counts, from 40, 000 cfu/L to 7 cfu/L, was found during the first year with silver-copper ionization. Nevertheless, the long-term efficacy of silver concentrations <10 ,++microg/L was not sufficient. Legionella counts increased to 10,000 cfu/L during the third year. During the fourth year, we studied the influence of higher silver concentrations on Legionella distribution. With an average silver level of 30 microg/L, only a 1.3-log reduction in Legionella, to 500 cfu/L, was achieved. The effect was not significant (P=.071); therefore, it must be considered that Legionella developed a tolerance to silver ions. (+info)

DNA cleavage activities of (-)-epigallocatechin, (-)-epicatechin, (+)-catechin, and (-)-epigallocatechin gallate with various kinds of metal ions. (8/1192)

The DNA cleavage activities of (+)-catechin (C), (-)-epicatechin (EC), (-)-epigallocatechin (EGC), and (-)-epigallocatechin gallate (EGCg) were examined with 16 different metal ions. Cu(2+) with all the catechins facilitated DNA cleavage, while Ag+ with EGC and EC showed a strong repressive effect. The other metal ions examined showed little effect. (+info)

I'm sorry for any confusion, but "Silver" is not a medical term. It is a chemical element with the symbol Ag and atomic number 47. Silver is a soft, white, lustrous transition metal that occurs in its pure, free form (native silver) as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.

In the medical field, silver compounds have been used for their antimicrobial properties. For example, silver sulfadiazine is a common topical cream used to prevent or treat wound infections. Colloidal silver, a suspension of silver particles in a liquid, has also been promoted as a dietary supplement and alternative treatment for various conditions, but its effectiveness and safety are not well-established.

Silver nitrate is defined as an inorganic compound with the chemical formula AgNO3. It is a white or colorless crystalline solid that is highly soluble in water. Silver nitrate is commonly used in medicine as a topical antiseptic and caustic, particularly for the treatment of wounds, ulcers, and warts. When applied to skin or mucous membranes, it can help to destroy bacteria, viruses, and fungi, and promote healing. However, it can also cause irritation and tissue damage if used inappropriately, so it should be used with caution and under the guidance of a healthcare professional.

Silver compounds refer to chemical substances that combine silver (Ag) with one or more other elements. In the medical context, silver compounds are known for their antimicrobial properties and have been used in various medical applications such as wound dressings, creams, and coatings on medical devices.

Some examples of silver compounds include:

* Silver sulfadiazine (AgSD): a common topical antibiotic used to prevent and treat bacterial infections in burn wounds.
* Silver nitrate (AgNO3): a strong antiseptic used to treat wounds, skin infections, and eye conditions such as neonatal conjunctivitis.
* Silver chloride (AgCl): a compound used in some wound dressings for its antimicrobial properties.
* Silver proteinate: a silver compound that is often used in dietary supplements and claimed to have immune-boosting and anti-inflammatory effects, although its efficacy is not well established.

It's important to note that while silver compounds can be effective antimicrobial agents, they can also have potential side effects such as skin irritation, discoloration, and in some cases, argyria (a bluish-gray discoloration of the skin caused by excessive accumulation of silver). Therefore, they should be used under the guidance of a healthcare professional.

"Silver staining" is a histological term that refers to a technique used to selectively stain various components of biological tissues, making them more visible under a microscope. This technique is often used in the study of histopathology and cytology. The most common type of silver staining is known as "silver impregnation," which is used to demonstrate the presence of argyrophilic structures, such as nerve fibers and neurofibrillary tangles, in tissues.

The process of silver staining involves the use of silver salts, which are reduced by a developer to form metallic silver that deposits on the tissue components. The intensity of the stain depends on the degree of reduction of the silver ions, and it can be modified by adjusting the concentration of the silver salt, the development time, and other factors.

Silver staining is widely used in diagnostic pathology to highlight various structures such as nerve fibers, axons, collagen, basement membranes, and microorganisms like fungi and bacteria. It has also been used in research to study the distribution and organization of these structures in tissues. However, it's important to note that silver staining is not specific for any particular substance, so additional tests are often needed to confirm the identity of the stained structures.

Silver Sulfadiazine is a topical antimicrobial cream, primarily used for the prevention and treatment of burn wounds' infections. It has broad-spectrum activity against various bacteria, including gram-positive and gram-negative organisms, as well as some fungi. The cream creates a physical barrier that helps minimize bacterial growth and contains silver, which has antimicrobial properties. Silver Sulfadiazine is often used in combination with other burn wound care treatments to optimize healing and reduce the risk of complications such as sepsis.

The medical definition of Silver Sulfadiazine can be stated as:

A topical antimicrobial agent, chemically described as silver(I) 1-(4-amino-2-sulfonylphenyl)-2-(N-pyrimidin-2-ylsulfamoyl)ethanone dihydrate. It is primarily used for the prevention and treatment of infections associated with burn wounds due to its broad-spectrum antibacterial and antifungal properties. The compound is available as a white cream, which forms a protective layer on the wound, releasing silver ions that inhibit bacterial growth and promote healing.

Medical definitions generally refer to terms and concepts within the medical field. The term "metal nanoparticles" is more commonly used in materials science, chemistry, and physics. However, I can provide a general scientific definition that could be relevant to medical applications:

Metal nanoparticles are tiny particles with at least one dimension ranging from 1 to 100 nanometers (nm), composed of metals or metal compounds. They have unique optical, electronic, and chemical properties due to their small size and high surface-to-volume ratio, making them useful in various fields, including medical research. In medicine, metal nanoparticles can be used in drug delivery systems, diagnostics, and therapeutic applications such as photothermal therapy and radiation therapy. Examples of metals used for nanoparticle synthesis include gold, silver, and iron.

Argyria is a rare, cosmetic condition that results from excessive exposure to silver and its compounds, leading to the accumulation of silver particles in various tissues of the body, particularly the skin. The most noticeable symptom of argyria is the development of a blue-gray or slate-gray discoloration of the skin, mucous membranes, and eyes. This condition is usually permanent and not harmful to one's health, but it can cause significant psychological distress due to its impact on appearance.

The primary causes of argyria are long-term use or misuse of silver-containing medications, dietary supplements, or topical products that contain silver compounds like silver nitrate, silver sulfadiazine, and colloidal silver. Prolonged exposure to silver dust in occupational settings can also lead to argyria.

It is important to note that argyria should not be confused with generalized silver toxicity or acute silver poisoning, which can have more severe health consequences.

"Green Chemistry Technology," also known as "Sustainable Chemistry," refers to the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. It aims to minimize negative impacts on human health and the environment, while maximizing economic benefits. This is achieved through the application of principles such as preventing waste, designing safer chemicals, using renewable feedstocks, and minimizing energy use. Green Chemistry Technology involves the development and implementation of novel chemical reactions, catalysts, and processes that are inherently safer and more environmentally benign than traditional methods.

Silver proteins are a type of compound that consists of silver ions (Ag+) bonded to protein molecules. These compounds are often used in medical applications, including topical creams and ointments, for their antimicrobial properties. The silver ions in the compound can help to kill or inhibit the growth of a wide range of microorganisms, including bacteria, fungi, and viruses.

The protein component of silver proteins helps to stabilize the silver ions and control their release, which can improve the efficacy and safety of the product. The protein may also help to enhance the penetration of the silver ions into the skin or other tissues, allowing for more effective killing of microorganisms.

Silver proteins are used in a variety of medical products, including wound dressings, creams and gels for the treatment of burns and other types of wounds, and as a coating on medical devices to prevent infection. They have been shown to be effective against a wide range of microorganisms, including antibiotic-resistant strains, making them a valuable tool in the fight against infectious diseases.

The Nucleolus Organizer Region (NOR) is a specific region within the chromosomes, primarily in the short arm of the acrocentric chromosomes (chromosomes 13, 14, 15, 21, and 22). It consists of clusters of repetitive DNA sequences that encode ribosomal RNA (rRNA) genes. During interphase, these regions form the nucleolus, a distinct structure within the nucleus where rRNA transcription, processing, and ribosome assembly occur. The number of NORs in an individual can vary, which has implications in certain genetic conditions and aging processes.

'Staining and labeling' are techniques commonly used in pathology, histology, cytology, and molecular biology to highlight or identify specific components or structures within tissues, cells, or molecules. These methods enable researchers and medical professionals to visualize and analyze the distribution, localization, and interaction of biological entities, contributing to a better understanding of diseases, cellular processes, and potential therapeutic targets.

Medical definitions for 'staining' and 'labeling' are as follows:

1. Staining: A process that involves applying dyes or stains to tissues, cells, or molecules to enhance their contrast and reveal specific structures or components. Stains can be categorized into basic stains (which highlight acidic structures) and acidic stains (which highlight basic structures). Common staining techniques include Hematoxylin and Eosin (H&E), which differentiates cell nuclei from the surrounding cytoplasm and extracellular matrix; special stains, such as PAS (Periodic Acid-Schiff) for carbohydrates or Masson's trichrome for collagen fibers; and immunostains, which use antibodies to target specific proteins.
2. Labeling: A process that involves attaching a detectable marker or tag to a molecule of interest, allowing its identification, quantification, or tracking within a biological system. Labels can be direct, where the marker is directly conjugated to the targeting molecule, or indirect, where an intermediate linker molecule is used to attach the label to the target. Common labeling techniques include fluorescent labels (such as FITC, TRITC, or Alexa Fluor), enzymatic labels (such as horseradish peroxidase or alkaline phosphatase), and radioactive labels (such as ³²P or ¹⁴C). Labeling is often used in conjunction with staining techniques to enhance the specificity and sensitivity of detection.

Together, staining and labeling provide valuable tools for medical research, diagnostics, and therapeutic development, offering insights into cellular and molecular processes that underlie health and disease.

Anti-infective agents, local, are medications that are applied directly to a specific area of the body to prevent or treat infections caused by bacteria, fungi, viruses, or parasites. These agents include topical antibiotics, antifungals, antivirals, and anti-parasitic drugs. They work by killing or inhibiting the growth of the infectious organisms, thereby preventing their spread and reducing the risk of infection. Local anti-infective agents are often used to treat skin infections, eye infections, and other localized infections, and can be administered as creams, ointments, gels, solutions, or drops.

In the context of medical and health sciences, particle size generally refers to the diameter or dimension of particles, which can be in the form of solid particles, droplets, or aerosols. These particles may include airborne pollutants, pharmaceutical drugs, or medical devices such as nanoparticles used in drug delivery systems.

Particle size is an important factor to consider in various medical applications because it can affect the behavior and interactions of particles with biological systems. For example, smaller particle sizes can lead to greater absorption and distribution throughout the body, while larger particle sizes may be filtered out by the body's natural defense mechanisms. Therefore, understanding particle size and its implications is crucial for optimizing the safety and efficacy of medical treatments and interventions.

I'm sorry for any confusion, but "nanocomposites" is not a term that has a specific medical definition. It is a term used in materials science and engineering to refer to a type of composite material where at least one of the phases has dimensions in the nanoscale (typically less than 100 nanometers). Nanocomposites can have unique properties that make them useful for various applications, including biomedical applications such as drug delivery systems or tissue engineering scaffolds. However, the term itself is not a medical definition.

I believe there may be some confusion in your question. Gold is typically a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable, and ductile metal. It is one of the least reactive chemical elements and is solid under standard conditions.

However, if you are referring to "Gold" in the context of medical terminology, it may refer to:

1. Gold salts: These are a group of compounds that contain gold and are used in medicine for their anti-inflammatory properties. They have been used in the treatment of rheumatoid arthritis, although they have largely been replaced by newer drugs with fewer side effects.
2. Gold implants: In some cases, a small amount of gold may be surgically implanted into the eye to treat conditions such as age-related macular degeneration or diabetic retinopathy. The gold helps to hold the retina in place and can improve vision in some patients.
3. Gold thread embedment: This is an alternative therapy used in traditional Chinese medicine, where gold threads are embedded into the skin or acupuncture points for therapeutic purposes. However, there is limited scientific evidence to support its effectiveness.

I hope this information helps! If you have any further questions, please let me know.

Colloids are a type of mixture that contains particles that are intermediate in size between those found in solutions and suspensions. These particles range in size from about 1 to 1000 nanometers in diameter, which is smaller than what can be seen with the naked eye, but larger than the molecules in a solution.

Colloids are created when one substance, called the dispersed phase, is dispersed in another substance, called the continuous phase. The dispersed phase can consist of particles such as proteins, emulsified fats, or finely divided solids, while the continuous phase is usually a liquid, but can also be a gas or a solid.

Colloids are important in many areas of medicine and biology, including drug delivery, diagnostic imaging, and tissue engineering. They are also found in nature, such as in milk, blood, and fog. The properties of colloids can be affected by factors such as pH, temperature, and the presence of other substances, which can influence their stability and behavior.

Transmission electron microscopy (TEM) is a type of microscopy in which an electron beam is transmitted through a ultra-thin specimen, interacting with it as it passes through. An image is formed from the interaction of the electrons with the specimen; the image is then magnified and visualized on a fluorescent screen or recorded on an electronic detector (or photographic film in older models).

TEM can provide high-resolution, high-magnification images that can reveal the internal structure of specimens including cells, viruses, and even molecules. It is widely used in biological and materials science research to investigate the ultrastructure of cells, tissues and materials. In medicine, TEM is used for diagnostic purposes in fields such as virology and bacteriology.

It's important to note that preparing a sample for TEM is a complex process, requiring specialized techniques to create thin (50-100 nm) specimens. These include cutting ultrathin sections of embedded samples using an ultramicrotome, staining with heavy metal salts, and positive staining or negative staining methods.

I'm sorry for any confusion, but "Foxes" is not a term that has a widely accepted or specific medical definition. The common fox (Vulpes vulpes) is a species of small omnivorous mammals, and while there can be medical issues related to foxes or other animals in certain contexts, such as zoonotic diseases, "Foxes" itself does not have a medical connotation. If you have any specific medical query, I'd be happy to try and help with that.

I'm sorry for any confusion, but "nanowires" is not a medical term. It is a term used in the field of materials science and nanotechnology. Nanowires are one-dimensional structures with a diameter of 1-100 nanometers (nm) and an aspect ratio (length/diameter) greater than 1000. They have unique electrical, mechanical, and optical properties that make them useful in various applications such as electronics, sensors, energy storage, and biomedical devices.
