5'-Nucleotidase activity of mouse peritoneal macrophages. II. Cellular distribution and effects of endocytosis. (1/496)
The diazonium salt of sulfanilic acid (DASA) can inactivate about 80% of the total 5'-nucleotidase of viable macrophages. The remaining 20% can be inactivated if the cells are first lysed in detergent, and presumably represents an intracellular pool of 5'-nucleotidase. The bulk of this pool may represent cytoplasmic vesicles derived from plasma membrane by endocytosis. This internal compartment is expanded up to threefold immediately after the cells have ingested a large latex load. This is consistent with previous observations on the internalization of 5'-nucleotidase in latex phagosomes. In latex-filled cells this intracellular pool of enzyme is inactivated over a few hours, and the cells then slowly increase their enzyme activity to nearly normal levels. However, 24 h after latex ingestion the metabolism of 5'-nucleotidase in these recovered cells is abnormal, as the rate of enzyme degradation is about twice the normal rate, and the DASA-insensitive enzyme pool in these cells is strikingly diminished. This may reflect effects of the accumulated indigestible particles on the fate of incoming pinocytic vesicles or on newly synthesized plasma membrane precursor. Another endocytic stimulus, concanavalin A, also reduces the total cell 5'-nucleotidase activity. This effect, which is time and temperature dependent, can be prevented by the competitive sugar alpha-methyl mannose. The concanavalin A inhibition can be reversed in the absence of new protein synthesis or in cells cultivated in serum-free conditions. It is not known whether the effect of concanavalin A on 5'-nucleotidase depends upon the interiorizaiton of plasma membrane or is strictly associated with events at the cell surface. (+info)Three-independent-compartment chamber to study in vitro commissural synapses. (2/496)
We describe a novel chamber in which the two intact neonatal rat hippocampi and the commissural fibers are placed in three independent compartments separated by latex membranes and perfused selectively with different solutions. A set of control tests showed that the compartments are well isolated: 1) methylene blue or eosin applied to one compartment did not diffuse to other compartments when verified via the microscope, and spectrophotometry revealed that <1/10.000th of the dye diffuses to other compartments; 2) tetrodotoxin (1 microM) applied to the commissural compartment blocked the synaptic responses evoked contralaterally without affecting those evoked on the ipsilateral side. This chamber enables a wide range of experiments that cannot be performed in conventional chambers, e.g., to study the maturation and plasticity of the commissural connections, bilateral synchronization of the rhythmic activities in the limbic system, commissural propagation of the epileptiform activities, etc. (+info)A new sugar chain of the proteinase inhibitor from latex of Carica papaya. (3/496)
The structure of a sugar chain of the proteinase inhibitor from the latex of Carica papaya was studied. Sugar chains liberated on hydrazinolysis were N-acetylated, and their reducing-end residues were tagged with 2-aminopyridine. One major sugar chain was detected on size-fractionation and reversed-phase HPLC analyses. The structure of the PA-sugar chain was determined by two-dimensional sugar mapping combined with sequential exoglycosidase digestion and partial acid hydrolysis, and by 750 MHz 1H-NMR spectroscopy. The structure found was Manalpha1-6(Manalpha1-3)Manalpha1-6(Manalpha1-3) (Xylbeta1-2)Manbeta1- 4GlcNAcbeta1-4(Fucalpha1-3)GlcNAc. This sugar chain represents a new plant-type sugar chain with five mannose residues. (+info)2-Deoxyglucose selectively inhibits Fc and complement receptor-mediated phagocytosis in mouse peritoneal macrophages. I. Description of the inhibitory effect. (4/496)
Incubation of normal or thioglycollate-elicited mouse peritoneal macrophages with 2-deoxy-D-glucose (2-dG) inhibits the capacity of these macrophages to phagocytize IgG- or complement-coated particles via their Fc and C3 receptors. 2-dG has no inhibitory effect on the capacity of these macrophages to phagocytize latex or zymosan particles, which are ingested in the absence of specific opsonins, and it does not inhibit binding of IgG- or C3-coated particles to their respective receptors on the macrophage's plasma membrane. 2-dG exerts its inhibitory effect on the macrophage and not on the opsonized particle. The inhibition is independent of particle size, occurs within 15-30 min of addition of this glucose analogue to the medium at 37 degrees C, cannot be overcome by supra-agglutinating amounts of opsonizing antibody, and is completely reversible by substitution of 5.5 mM glucose for 50 mM 2-dG in the medium. Addition of equimolar amounts of glucose or mannose, but not of fructose, galactose, fucose, or glucosamine, to medium containing 50 mM 2-dG results in substantial reversal of the inhibitory effect of 2-dG on Fc and C3 receptor mediated phagocytosis. (+info)Discrimination of DNA hybridization using chemical force microscopy. (5/496)
Atomic force microscopy (AFM) can be used to probe the mechanics of molecular recognition between surfaces. In the application known as "chemical force" microscopy (CFM), a chemically modified AFM tip probes a surface through chemical recognition. When modified with a biological ligand or receptor, the AFM tip can discriminate between its biological binding partner and other molecules on a heterogeneous substrate. The strength of the interaction between the modified tip and the substrate is governed by the molecular affinity. We have used CFM to probe the interactions between short segments of single-strand DNA (oligonucleotides). First, a latex microparticle was modified with the sequence 3'-CAGTTCTACGATGGCAAGTC and epoxied to a standard AFM cantilever. This DNA-modified probe was then used to scan substrates containing the complementary sequence 5'-GTCAAGATGCTACCGTTCAG. These substrates consisted of micron-scale, patterned arrays of one or more distinct oligonucleotides. A strong friction interaction was measured between the modified tip and both elements of surface-bound DNA. Complementary oligonucleotides exhibited a stronger friction than the noncomplementary sequences within the patterned array. The friction force correlated with the measured strength of adhesion (rupture force) for the tip- and array-bound oligonucleotides. This result is consistent with the formation of a greater number of hydrogen bonds for the complementary sequence, suggesting that the friction arises from a sequence-specific interaction (hybridization) of the tip and surface DNA. (+info)Studies in calf venous pump function utilizing a two-valve experimental model. (6/496)
OBJECTIVES: to explore the hydrodynamic mechanisms involved in the regulation of ambulatory venous pressure. DESIGN: an experimental model of calf venous pump was constructed with collapsible tubes and valves. MATERIAL: the model consisted of a conduit and a pump with an intervening competent valve. Another valve that could allow reflux into the pump was mounted above the pump. METHODS: conduit pressure and recovery times were monitored under conditions of different degrees of ejection fraction and reflux into the pump. Model variables included using poorly compliant tubes for the pump, the conduit and for both the pump and conduit. RESULTS: the latex tube exhibited a non-linear volume-pressure relationship and a bi-modal regimen of compliance. This bestowed pressure-buffering properties. Ambulatory venous hypertension resulted when reflux beyond buffering capacity occurred. Substituting less compliant PTFE for latex at the pump had a relatively minor effect on post-ejection pressure and recovery times. Using PTFE at the conduit had a profound but divergent effect on both of these parameters. Conduit capacitance reduction had a similar effect. CONCLUSION: conduit elastance plays a significant role in the regulation of ambulatory venous pressure in this experimental model. The hydrodynamic principles illustrated by the model may enhance our understanding of the human calf venous pump. (+info)Separation of submicron bioparticles by dielectrophoresis. (7/496)
Submicron particles such as latex spheres and viruses can be manipulated and characterized using dielectrophoresis. By the use of appropriate microelectrode arrays, particles can be trapped or moved between regions of high or low electric fields. The magnitude and direction of the dielectrophoretic force on the particle depends on its dielectric properties, so that a heterogeneous mixture of particles can be separated to produce a more homogeneous population. In this paper the controlled separation of submicron bioparticles is demonstrated. With electrode arrays fabricated using direct write electron beam lithography, it is shown that different types of submicron latex spheres can be spatially separated. The separation occurs as a result of differences in magnitude and/or direction of the dielectrophoretic force on different populations of particles. These differences arise mainly because the surface properties of submicron particles dominate their dielectrophoretic behavior. It is also demonstrated that tobacco mosaic virus and herpes simplex virus can be manipulated and spatially separated in a microelectrode array. (+info)Adhesive properties of the isolated amino-terminal domain of platelet glycoprotein Ibalpha in a flow field. (8/496)
We have examined the interaction between the amino-terminal domain of platelet glycoprotein (GP) Ibalpha and immobilized von Willebrand Factor (vWF) under flow conditions in the absence of other components of the GP Ib-IX-V complex. Latex beads were coated with a recombinant fragment containing GP Ibalpha residues 1-302, either with normal sequence or with the single G233V substitution that causes enhanced affinity for plasma vWF in platelet-type pseudo-von-Willebrand disease. Beads coated with native fragment adhered to vWF in a manner comparable to platelets, showing surface translocation that reflected the transient nature of the bonds formed. Thus, the GP Ibalpha extracellular domain is necessary and sufficient for interacting with vWF under high shear stress. Beads coated with the mutated fragment became tethered to vWF in greater number and had lower velocity of translocation than beads coated with the normal counterpart, suggesting that the G233V mutation lowers the rate of bond dissociation. Our findings define an approach for studying the biomechanical properties of the GP Ibalpha-vWF bond and suggest that this interaction is tightly regulated to allow rapid binding at sites of vascular injury, while permitting the concurrent presence of receptor and ligand in the circulation. (+info)In a medical context, "latex" refers to the natural rubber milk-like substance that is tapped from the incisions made in the bark of the rubber tree (Hevea brasiliensis). This sap is then processed to create various products such as gloves, catheters, and balloons. It's important to note that some people may have a latex allergy, which can cause mild to severe reactions when they come into contact with latex products.
Latex fixation tests are diagnostic procedures used to detect the presence of certain antigens or antibodies in a patient's sample, such as blood or serum. These tests use latex particles that are coated with specific antigens or antibodies that can bind to complementary antigens or antibodies present in the sample. When the sample is added to the latex reagent, if the specific antigen or antibody is present, they will bind to the latex particles, forming an agglutination reaction that can be seen as a visible clumping or agglutination of the latex particles.
Latex fixation tests are commonly used in the diagnosis of infectious diseases, autoimmune disorders, and genetic disorders. For example, a latex fixation test may be used to detect the presence of Streptococcus pneumoniae antigens in a patient's sputum sample or to identify the presence of rheumatoid factor (RF) antibodies in a patient's blood sample. These tests are known for their simplicity, speed, and sensitivity, making them a valuable tool in clinical laboratories.
I believe there may be some confusion in your question. "Rubber" is not a medical term, but rather a common term used to describe a type of material that is elastic and can be stretched or deformed and then return to its original shape when the force is removed. It is often made from the sap of rubber trees or synthetically.
However, in a medical context, "rubber" might refer to certain medical devices or supplies made from rubber materials, such as rubber gloves used for medical examinations or procedures, or rubber stoppers used in laboratory equipment. But there is no medical definition specifically associated with the term 'Rubber' itself.
Surgical gloves are a form of personal protective equipment (PPE) used by healthcare professionals during medical procedures, particularly surgical procedures. They are designed to provide a barrier between the healthcare professional's hands and the patient's sterile field, helping to prevent contamination and reduce the risk of infection.
Surgical gloves are typically made of latex, nitrile rubber, or vinyl and come in various sizes to fit different hand shapes and sizes. They have a powder-free interior and an exterior that is coated with a substance to make them easier to put on and remove. The gloves are usually sterile and are packaged in pairs, often with a protective covering to maintain their sterility until they are ready to be used.
The use of surgical gloves is a critical component of standard precautions, which are measures taken to prevent the transmission of infectious agents from patients to healthcare professionals or from one patient to another. By wearing surgical gloves, healthcare professionals can protect themselves and their patients from potentially harmful bacteria, viruses, and other microorganisms that may be present during medical procedures.
"Hevea" is the genus name for the rubber tree, specifically *Hevea brasiliensis*, which is the primary source of natural rubber. The sap from this tree, known as latex, is collected and processed to produce raw rubber. This material can then be used in a wide variety of applications, including medical devices, tires, and various other products.
It's worth noting that some people may have allergic reactions to proteins found in natural rubber latex, which can cause symptoms ranging from mild skin irritation to severe respiratory problems. As such, it's important for healthcare providers and others who work with medical equipment to be aware of the potential risks associated with Hevea-derived products.
Protective gloves are a type of personal protective equipment (PPE) used to shield the hands from potential harm or contamination. They can be made from various materials such as latex, nitrile rubber, vinyl, or polyethylene and are designed to provide a barrier against chemicals, biological agents, radiation, or mechanical injuries. Protective gloves come in different types, including examination gloves, surgical gloves, chemical-resistant gloves, and heavy-duty work gloves, depending on the intended use and level of protection required.
'Calotropis' is a genus of flowering plants in the family Apocynaceae, also known as milkweeds or crownflowers. There are two main species within this genus: Calotropis procera and Calotropis gigantea. These plants are native to tropical and subtropical regions of Africa, Asia, and Australia. They have large, showy flowers and produce a milky sap that contains latex. Some parts of these plants, such as the roots and leaves, have been used in traditional medicine for various purposes, including treating skin conditions, inflammation, and pain. However, it is important to note that all parts of Calotropis plants contain toxic compounds and can cause serious side effects if ingested or applied improperly. Therefore, they should only be used under the guidance of a qualified healthcare professional.
Microspheres are tiny, spherical particles that range in size from 1 to 1000 micrometers in diameter. They are made of biocompatible and biodegradable materials such as polymers, glass, or ceramics. In medical terms, microspheres have various applications, including drug delivery systems, medical imaging, and tissue engineering.
In drug delivery, microspheres can be used to encapsulate drugs and release them slowly over time, improving the efficacy of the treatment while reducing side effects. They can also be used for targeted drug delivery, where the microspheres are designed to accumulate in specific tissues or organs.
In medical imaging, microspheres can be labeled with radioactive isotopes or magnetic materials and used as contrast agents to enhance the visibility of tissues or organs during imaging procedures such as X-ray, CT, MRI, or PET scans.
In tissue engineering, microspheres can serve as a scaffold for cell growth and differentiation, promoting the regeneration of damaged tissues or organs. Overall, microspheres have great potential in various medical applications due to their unique properties and versatility.
Euphorbiaceae is not a medical term, but a taxonomic category in botany. It refers to the spurge family, which is a large family of flowering plants that includes around 300 genera and 7,500 species. Some members of this family have medicinal uses, but others are toxic or invasive. Therefore, it is important to use caution when handling or consuming any plant material from this family.
Euphorbia is a genus of plants that belongs to the spurge family (Euphorbiaceae). It contains around 2,000 species of shrubs, trees, and herbs that are found worldwide, particularly in tropical and subtropical regions. Many euphorbias are known for their milky sap, which can be toxic or irritating to the skin and mucous membranes. Some species of euphorbia are cultivated as ornamental plants due to their attractive flowers and foliage, while others have medicinal or industrial uses. However, it's important to note that some euphorbias can be invasive and harmful to local ecosystems, so care should be taken when handling or growing them.
Occupational dermatitis is a specific type of contact dermatitis that results from exposure to certain substances or conditions in the workplace. It can be caused by direct contact with chemicals, irritants, or allergens present in the work environment. This condition typically affects the skin on the hands and forearms but can also involve other areas of the body, depending on the nature of the exposure.
There are two main types of occupational dermatitis:
1. Irritant contact dermatitis (ICD): This type occurs when the skin comes into direct contact with an irritating substance, leading to redness, swelling, itching, and sometimes blistering. Common irritants include solvents, detergents, oils, and other industrial chemicals.
2. Allergic contact dermatitis (ACD): This type is a result of an allergic reaction to a specific substance. The immune system identifies the allergen as harmful and mounts a response, causing skin inflammation. Common allergens include latex, metals (such as nickel), and certain plants (like poison ivy).
Prevention measures for occupational dermatitis include using appropriate personal protective equipment (PPE) like gloves, masks, and aprons, as well as practicing good hygiene, such as washing hands regularly and avoiding touching the face with contaminated hands. If you suspect you have developed occupational dermatitis, consult a healthcare professional for proper diagnosis and treatment.
Phagocytosis is the process by which certain cells in the body, known as phagocytes, engulf and destroy foreign particles, bacteria, or dead cells. This mechanism plays a crucial role in the immune system's response to infection and inflammation. Phagocytes, such as neutrophils, monocytes, and macrophages, have receptors on their surface that recognize and bind to specific molecules (known as antigens) on the target particles or microorganisms.
Once attached, the phagocyte extends pseudopodia (cell extensions) around the particle, forming a vesicle called a phagosome that completely encloses it. The phagosome then fuses with a lysosome, an intracellular organelle containing digestive enzymes and other chemicals. This fusion results in the formation of a phagolysosome, where the engulfed particle is broken down by the action of these enzymes, neutralizing its harmful effects and allowing for the removal of cellular debris or pathogens.
Phagocytosis not only serves as a crucial defense mechanism against infections but also contributes to tissue homeostasis by removing dead cells and debris.
"Carica" is a genus name that refers to a group of plants commonly known as papayas. The most widely cultivated and well-known species in this genus is Carica papaya, which is native to Central America and southern Mexico. This plant produces large, edible fruits that are rich in nutrients such as vitamin C, vitamin A, and potassium.
The fruit of the Carica papaya tree is often used for its medicinal properties, including its anti-inflammatory and digestive benefits. The leaves, stems, and roots of the plant also have various traditional uses in different cultures, such as treating wounds, reducing fever, and alleviating symptoms of digestive disorders.
It's worth noting that while Carica papaya has been studied for its potential health benefits, more research is needed to fully understand its effects and safety profile. As with any treatment or supplement, it's important to consult with a healthcare provider before using Carica papaya for medicinal purposes.
Skin tests are medical diagnostic procedures that involve the application of a small amount of a substance to the skin, usually through a scratch, prick, or injection, to determine if the body has an allergic reaction to it. The most common type of skin test is the patch test, which involves applying a patch containing a small amount of the suspected allergen to the skin and observing the area for signs of a reaction, such as redness, swelling, or itching, over a period of several days. Another type of skin test is the intradermal test, in which a small amount of the substance is injected just beneath the surface of the skin. Skin tests are used to help diagnose allergies, including those to pollen, mold, pets, and foods, as well as to identify sensitivities to medications, chemicals, and other substances.
Agglutination tests are laboratory diagnostic procedures used to detect the presence of antibodies or antigens in a sample, such as blood or serum. These tests work by observing the clumping (agglutination) of particles, like red blood cells or bacteriophages, coated with specific antigens or antibodies when mixed with a patient's sample.
In an agglutination test, the sample is typically combined with a reagent containing known antigens or antibodies on the surface of particles, such as latex beads, red blood cells, or bacteriophages. If the sample contains the corresponding antibodies or antigens, they will bind to the particles, forming visible clumps or agglutinates. The presence and strength of agglutination are then assessed visually or with automated equipment to determine the presence and quantity of the target antigen or antibody in the sample.
Agglutination tests are widely used in medical diagnostics for various applications, including:
1. Bacterial and viral infections: To identify specific bacterial or viral antigens in a patient's sample, such as group A Streptococcus, Legionella pneumophila, or HIV.
2. Blood typing: To determine the ABO blood group and Rh type of a donor or recipient before a blood transfusion or organ transplantation.
3. Autoimmune diseases: To detect autoantibodies in patients with suspected autoimmune disorders, such as rheumatoid arthritis, systemic lupus erythematosus, or Hashimoto's thyroiditis.
4. Allergies: To identify specific IgE antibodies in a patient's sample to determine allergic reactions to various substances, such as pollen, food, or venom.
5. Drug monitoring: To detect and quantify the presence of drug-induced antibodies, such as those developed in response to penicillin or hydralazine therapy.
Agglutination tests are simple, rapid, and cost-effective diagnostic tools that provide valuable information for clinical decision-making and patient management. However, they may have limitations, including potential cross-reactivity with other antigens, false-positive results due to rheumatoid factors or heterophile antibodies, and false-negative results due to the prozone effect or insufficient sensitivity. Therefore, it is essential to interpret agglutination test results in conjunction with clinical findings and other laboratory data.
An antigen is any substance that can stimulate an immune response, leading to the production of antibodies or activation of immune cells. In plants, antigens are typically found on the surface of plant cells and may be derived from various sources such as:
1. Pathogens: Plant pathogens like bacteria, viruses, fungi, and oomycetes have unique molecules on their surfaces that can serve as antigens for the plant's immune system. These antigens are recognized by plant pattern recognition receptors (PRRs) and trigger an immune response.
2. Endogenous proteins: Some plant proteins, when expressed in abnormal locations or quantities, can be recognized as foreign by the plant's immune system and elicit an immune response. These proteins may serve as antigens and are involved in self/non-self recognition.
3. Glycoproteins: Plant cell surface glycoproteins, which contain carbohydrate moieties, can also act as antigens. They play a role in plant-microbe interactions and may be recognized by both the plant's immune system and pathogens.
4. Allergens: Certain plant proteins can cause allergic reactions in humans and animals when ingested or inhaled. These proteins, known as allergens, can also serve as antigens for the human immune system, leading to the production of IgE antibodies and triggering an allergic response.
5. Transgenic proteins: In genetically modified plants, new proteins introduced through genetic engineering may be recognized as foreign by the plant's immune system or even by the human immune system in some cases. These transgenic proteins can serve as antigens and have been a subject of concern in relation to food safety and potential allergies.
Understanding plant antigens is crucial for developing effective strategies for plant disease management, vaccine development, and improving food safety and allergy prevention.
