Fibroin allergy. IgE mediated hypersensitivity to silk suture materials. (1/375)
Delayed-type hypersensitivity with granulomatous lesions to silk sutures is rather rare. Yet, braided silk sutures often act as a non-immunologic foreign-body and cause a granulomatous inflammatory reaction years after surgery. We report here a case of recurrent granulomas with remarkable infiltration of eosinophils that may have resulted from an IgE-mediated hypersensitivity reaction to silk fibroin, a component of the braided silk suture. Under normal circumstances exposure to fibroin is rather rare. Therefore, the present patient may have developed this reaction to the silk sutures used in a previous surgery. (+info)The mechanical design of spider silks: from fibroin sequence to mechanical function. (2/375)
Spiders produce a variety of silks, and the cloning of genes for silk fibroins reveals a clear link between protein sequence and structure-property relationships. The fibroins produced in the spider's major ampullate (MA) gland, which forms the dragline and web frame, contain multiple repeats of motifs that include an 8-10 residue long poly-alanine block and a 24-35 residue long glycine-rich block. When fibroins are spun into fibres, the poly-alanine blocks form (&bgr;)-sheet crystals that crosslink the fibroins into a polymer network with great stiffness, strength and toughness. As illustrated by a comparison of MA silks from Araneus diadematus and Nephila clavipes, variation in fibroin sequence and properties between spider species provides the opportunity to investigate the design of these remarkable biomaterials. (+info)Conformational transitions in model silk peptides. (3/375)
Protein structural transitions and beta-sheet formation are a common problem both in vivo and in vitro and are of critical relevance in disparate areas such as protein processing and beta-amyloid and prion behavior. Silks provide a "databank" of well-characterized polymorphic sequences, acting as a window onto structural transitions. Peptides with conformationally polymorphic silk-like sequences, expected to exhibit an intractable beta-sheet form, were characterized using Fourier transform infrared spectroscopy, circular dichroism, and electron diffraction. Polymorphs resembling the silk I, silk II (beta-sheet), and silk III (threefold polyglycine II-like helix) crystal structures were identified for the peptide fibroin C (GAGAGS repetitive sequence). Two peptides based on silk amorphous sequences, fibroin A (GAGAGY) and fibroin V (GDVGGAGATGGS), crystallized as silk I under most conditions. Methanol treatment of fibroin A resulted in a gradual transition from silk I to silk II, with an intermediate state involving a high proportion of beta-turns. Attenuated total reflectance Fourier transform infrared spectroscopy has been used to observe conformational changes as the peptides adsorb from solution onto a hydrophobic surface. Fibroin C has a beta-strand structure in solution but adopts a silk I-like structure upon adsorption, which when dried on the ZnSe crystal contains silk III crystallites. (+info)Fine organization of Bombyx mori fibroin heavy chain gene. (4/375)
The complete sequence of the Bombyx mori fibroin gene has been determined by means of combining a shotgun sequencing strategy with physical map-based sequencing procedures. It consists of two exons (67 and 15 750 bp, respectively) and one intron (971 bp). The fibroin coding sequence presents a spectacular organization, with a highly repetitive and G-rich (approximately 45%) core flanked by non-repetitive 5' and 3' ends. This repetitive core is composed of alternate arrays of 12 repetitive and 11 amorphous domains. The sequences of the amorphous domains are evolutionarily conserved and the repetitive domains differ from each other in length by a variety of tandem repeats of subdomains of approximately 208 bp which are reminiscent of the repetitive nucleosome organization. A typical composition of a subdomain is a cluster of repetitive units, Ua, followed by a cluster of units, Ub, (with a Ua:Ub ratio of 2:1) flanked by conserved boundary elements at the 3' end. Moreover some repeats are also perfectly conserved at the peptide level indicating that the evolutionary pressure is not identical along the sequence. A tentative model for the constitution and evolution of this unusual gene is discussed. (+info)The fine structure of silk fibroin. (5/375)
The fine structure of Bombyx mori silk fibroin was investigated by electron microscopy and X-ray diffraction techniques. Examination of silk fibers fragmented with ultrasonic radiation and negatively stained revealed the presence of ribbon-like filaments of well-defined lateral dimensions. Analysis of the breadths of the equatorial reflections in the X-ray diffraction pattern of fibroin yielded similar dimensions for the lateral extent of the crystallites. It is concluded that the crystalline material in B. mori silk fibroin is in the form of ribbon-like filaments of considerable length parallel to the fiber axis and of lateral dimensions approximately 20 x 60 A. (+info)Silk fibroin of Bombyx mori is secreted, assembling a high molecular mass elementary unit consisting of H-chain, L-chain, and P25, with a 6:6:1 molar ratio. (6/375)
Silk fibroin produced by the silkworm Bombyx mori consists of a heavy chain, a light chain, and a glycoprotein, P25. The heavy and light chains are linked by a disulfide bond, and P25 associates with disulfide-linked heavy and light chains by noncovalent interactions. Quantitative enzyme-linked immunosorbent assay revealed that molar ratios of the heavy chain, light chain, and P25 were 6:6:1, both in cocoons and in fibroin secreted into the lumen of posterior silk gland. Trace amounts of fibroin produced by three "naked pupa" mutants of B. mori lacked the light chain, but the molar ratio of heavy chain and P25 was also 6:1. Gel filtration chromatography and sedimentation equilibrium analysis demonstrated that a large protein complex of approximately 2.3 MDa, designated an elementary unit of fibroin having 6:6:1 molar ratios of the heavy chain, light chain, and P25, existed in posterior silk gland cells. Inaccessibility of biotinylated concanavalin A to the native elementary unit and partial dissociation of the elementary unit after incubation with excess N-glycosidase F or endoglycosidase H suggest that a single molecule of P25 is located internally and plays an important role in maintaining integrity of the complex. (+info)Sulfated fibroin, a novel sulfated peptide derived from silk, inhibits human immunodeficiency virus replication in vitro. (7/375)
We prepared two kinds of sulfated silk fibroins, SclFib30 and SclFib31, which contain different amounts of sulfate. These sulfated silk fibroins have anti-HIV-1 activity in vitro, apparently due to interference with the adsorption of virus particles to CD4+ cells, and completely blocked virus binding to the cells at a concentration of 100 microg/ml. Sulfated fibroins also abolished cell-to-cell infection-induced syncytium formation upon cocultivation of MOLT-4 and MOLT-4/HIV-IIIB cells, suggesting that they would interfere with gp120 and prevent the formation of gp120/CD4 complex. Silk is used in biomaterials such as surgical sutures and is believed to be a safe material for humans. In accordance with low anticoagulant activity and high anti-HIV-1 activity against both X4 HIV-1 and R5 HIV-1 strains, sulfated silk fibroins have potential as antiviral material such for a vaginal anti-HIV formulation. (+info)Evidence for diet effects on the composition of silk proteins produced by spiders. (8/375)
Silks are highly expressed, secreted proteins that represent a substantial metabolic cost to the insects and spiders that produce them. Female spiders in the superfamily Araneoidea (the orb-spinning spiders and their close relatives) spin six different kinds of silk (three fibroins and three fibrous protein glues) that differ in amino acid content and protein structure. In addition to this diversity in silks produced by different glands, we found that individual spiders of the same species can spin dragline silks (drawn from the spider's ampullate gland) that vary in content as well. Freely foraging ARGIOPE: argentata (Araneae: Araneoidea), collected from 13 Caribbean islands, produced dragline silk that showed an inverse relationship between the amount of serine and glycine they contained. X-ray microdiffraction of the silks localized these differences to the amorphous regions of the protein that are thought to lend silks their elasticity. The crystalline regions of the proteins, which lend silks their strength, were unaffected. Laboratory experiments with ARGIOPE: keyserlingi suggested that variation in silk composition reflects the type of prey the spiders were fed but not the total amount of prey they received. Hence, it may be that the amino acid content (and perhaps the mechanical properties) of dragline silk spun by ARGIOPE: directly reflect the spiders' diet. The ability to vary silk composition and, possibly, function is particularly important for organisms that disperse broadly, such as Argiope, and that occupy diverse habitats with diverse populations of prey. (+info)I'm sorry for any confusion, but "Silk" is not a medical term. Silk is a natural protein fiber, mainly composed of fibroin and produced by certain insect larvae to form cocoons. It's commonly used in textiles and other industries for its softness, smoothness, and strength. If you have any questions related to medical terminology or health-related topics, I'd be happy to help with those instead!
CD14 is a type of protein found on the surface of certain cells in the human body, including monocytes, macrophages, and some types of dendritic cells. These cells are part of the immune system and play a crucial role in detecting and responding to infections and other threats.
CD14 is not an antigen itself, but it can bind to certain types of antigens, such as lipopolysaccharides (LPS) found on the surface of gram-negative bacteria. When CD14 binds to an LPS molecule, it helps to activate the immune response and trigger the production of cytokines and other inflammatory mediators.
CD14 can also be found in soluble form in the bloodstream, where it can help to neutralize LPS and prevent it from causing damage to tissues and organs.
It's worth noting that while CD14 plays an important role in the immune response, it is not typically used as a target for vaccines or other immunotherapies. Instead, it is often studied as a marker of immune activation and inflammation in various diseases, including sepsis, atherosclerosis, and Alzheimer's disease.
I'm sorry for any confusion, but "spiders" is not a term that has a specific medical definition. It is a common name used to refer to arachnids of the order Araneae, characterized by having two main body parts (the cephalothorax and abdomen), eight legs, and fangs that inject venom.
However, in a medical context, "spider" or "spider bite" may be used to describe skin lesions or reactions resulting from the bite of certain spiders, particularly those with medically significant venoms. For example, necrotic arachnidism is a condition caused by the bite of some spider species, such as recluse spiders (Loxosceles spp.). The bites can cause skin necrosis and other systemic symptoms in severe cases.
If you are looking for information on a specific medical topic or condition, please provide more details so I can offer a more accurate response.
"Bombyx" is a genus name that refers to a group of insects in the family Bombycidae, which are known as silk moths. The most well-known species in this genus is "Bombyx mori," which is the domesticated silkworm used for commercial silk production.
The term "Bombyx" itself does not have a specific medical definition, but it is sometimes used in medical or scientific contexts to refer to this group of insects or their characteristics. For example, researchers might study the effects of Bombyx mori silk on wound healing or tissue regeneration.
It's worth noting that while some species of moths and butterflies can be harmful to human health in certain circumstances (such as by acting as vectors for diseases), the Bombyx genus is not typically considered a medical concern.
The black widow spider (Latrodectus mactans) is a species of venomous spider known for the distinctive, hourglass-shaped marking on its abdomen. It is found throughout North America and in parts of Europe, Africa, Asia, and South America. The female black widow spider is typically black or dark brown with a red or orange hourglass-shaped marking on the underside of her abdomen. She is larger than the male, measuring about 1/2 inch in length, while the male is smaller and usually light brown or grayish in color.
The black widow spider's venom contains a neurotoxin called alpha-latrotoxin, which can cause muscle pain, rigidity, and severe cramping. Bites from this spider are rarely fatal to healthy adults but can be dangerous to young children, the elderly, and those with compromised immune systems. Symptoms of a black widow bite may include nausea, sweating, and difficulty breathing.
Black widow spiders build irregular, tangled webs in dark, secluded areas such as woodpiles, sheds, and outdoor toilets. They are not aggressive by nature but will bite if they feel threatened or disturbed. It is essential to seek medical attention immediately if you suspect a black widow spider bite. Treatment may include pain medication, muscle relaxants, and in severe cases, antivenin therapy.
Insect vectors are insects that transmit disease-causing pathogens (such as viruses, bacteria, parasites) from one host to another. They do this while feeding on the host's blood or tissues. The insects themselves are not infected by the pathogen but act as mechanical carriers that pass it on during their bite. Examples of diseases spread by insect vectors include malaria (transmitted by mosquitoes), Lyme disease (transmitted by ticks), and plague (transmitted by fleas). Proper prevention measures, such as using insect repellent and reducing standing water where mosquitoes breed, can help reduce the risk of contracting these diseases.
Exocrine glands are a type of gland in the human body that produce and release substances through ducts onto an external or internal surface. These glands are responsible for secreting various substances such as enzymes, hormones, and lubricants that help in digestion, protection, and other bodily functions.
Exocrine glands can be further classified into three types based on their mode of secretion:
1. Merocrine glands: These glands release their secretions by exocytosis, where the secretory product is enclosed in a vesicle that fuses with the cell membrane and releases its contents outside the cell. Examples include sweat glands and mucous glands.
2. Apocrine glands: These glands release their secretions by pinching off a portion of the cytoplasm along with the secretory product. An example is the apocrine sweat gland found in the armpits and genital area.
3. Holocrine glands: These glands release their secretions by disintegrating and releasing the entire cell, including its organelles and secretory products. An example is the sebaceous gland found in the skin, which releases an oily substance called sebum.
Biocompatible materials are non-toxic and non-reacting substances that can be used in medical devices, tissue engineering, and drug delivery systems without causing harm or adverse reactions to living tissues or organs. These materials are designed to mimic the properties of natural tissues and are able to integrate with biological systems without being rejected by the body's immune system.
Biocompatible materials can be made from a variety of substances, including metals, ceramics, polymers, and composites. The specific properties of these materials, such as their mechanical strength, flexibility, and biodegradability, are carefully selected to meet the requirements of their intended medical application.
Examples of biocompatible materials include titanium used in dental implants and joint replacements, polyethylene used in artificial hips, and hydrogels used in contact lenses and drug delivery systems. The use of biocompatible materials has revolutionized modern medicine by enabling the development of advanced medical technologies that can improve patient outcomes and quality of life.
Tissue scaffolds, also known as bioactive scaffolds or synthetic extracellular matrices, refer to three-dimensional structures that serve as templates for the growth and organization of cells in tissue engineering and regenerative medicine. These scaffolds are designed to mimic the natural extracellular matrix (ECM) found in biological tissues, providing a supportive environment for cell attachment, proliferation, differentiation, and migration.
Tissue scaffolds can be made from various materials, including naturally derived biopolymers (e.g., collagen, alginate, chitosan, hyaluronic acid), synthetic polymers (e.g., polycaprolactone, polylactic acid, poly(lactic-co-glycolic acid)), or a combination of both. The choice of material depends on the specific application and desired properties, such as biocompatibility, biodegradability, mechanical strength, and porosity.
The primary functions of tissue scaffolds include:
1. Cell attachment: Providing surfaces for cells to adhere, spread, and form stable focal adhesions.
2. Mechanical support: Offering a structural framework that maintains the desired shape and mechanical properties of the engineered tissue.
3. Nutrient diffusion: Ensuring adequate transport of nutrients, oxygen, and waste products throughout the scaffold to support cell survival and function.
4. Guided tissue growth: Directing the organization and differentiation of cells through spatial cues and biochemical signals.
5. Biodegradation: Gradually degrading at a rate that matches tissue regeneration, allowing for the replacement of the scaffold with native ECM produced by the cells.
Tissue scaffolds have been used in various applications, such as wound healing, bone and cartilage repair, cardiovascular tissue engineering, and neural tissue regeneration. The design and fabrication of tissue scaffolds are critical aspects of tissue engineering, aiming to create functional substitutes for damaged or diseased tissues and organs.
I'm sorry for any confusion, but "mechanical phenomena" is not a standard medical term. The term "mechanical phenomenon" is more commonly used in the fields of physics and engineering to refer to events or processes that involve physical forces and movements, such as the movement of a lever or the flow of a fluid due to pressure differences.
If you have any questions about a specific medical concept or condition, I would be happy to try to help you with that instead!
Thermogravimetry (TG) is a technique used in materials science and analytical chemistry to measure the mass of a substance as a function of temperature while it is subjected to a controlled heating or cooling rate in a carefully controlled atmosphere. The sample is placed in a pan which is suspended from a balance and heated at a constant rate. As the temperature increases, various components of the sample may decompose, lose water, or evolve gases, resulting in a decrease in mass, which is recorded by the balance.
TG can be used to determine the weight loss due to decomposition, desorption, or volatilization, and to calculate the amount of various components present in a sample. It is often used in conjunction with other techniques such as differential thermal analysis (DTA) or differential scanning calorimetry (DSC) to provide additional information about the thermal behavior of materials.
In summary, thermogravimetry is a method for measuring the mass changes of a material as it is heated or cooled, which can be used to analyze its composition and thermal stability.
Tensile strength is a material property that measures the maximum amount of tensile (pulling) stress that a material can withstand before failure, such as breaking or fracturing. It is usually measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa). In the context of medical devices or biomaterials, tensile strength may be used to describe the mechanical properties of materials used in implants, surgical tools, or other medical equipment. High tensile strength is often desirable in these applications to ensure that the material can withstand the stresses and forces it will encounter during use.
