Effect of physical parameters on the in situ survival of Escherichia coli MC-6 in an estuarine environment. (1/98)
Survival of Escherichia coli MC-6 of fecal origin in an estuarine environment as affected by time, water temperature, dissolved oxygen, salinity, and montmorillonite in diffusion chambers has been elucidated. Several in situ physical parameters were recorded simultaneously, and viable cell numbers were estimated. The survival of the bacteria varied seasonally. Montmorillonite addition extended the time needed for a 50% reduction of the viable cell population (t1/2) of cells by 40% over the t1/2 of cells in Rhode River water alone. The effect of this clay was not significantly greater between 50- to 1,000 mug/ml montmorillonite concentrations. In all experiments, the relationships among pairs of variables were studied by regression and correlation analysis. The slope between viable cell numbers and water temperatures increased about 50% for each 10 C increment in temperature and gave a correlation coefficient r = 0.617, significant at 95% confidence level. A similar correlation coefficient, r = 0.670, was obtained between water temperature and t1/2 of the initial cell population. In all experiments regressions were performed considering all variables after bacteria had been in the Rhode River environment for 3 days. Coefficient of multiple determination was estimated as R2 = 0.756. Approximately 75.6% of the variance of viable cell numbers can be explained by variation in water temperature, dissolved oxygen, and salinity. Simple correlation coefficients within the regression steps were also computed. Survival of bacteria was closely and negatively correlated with increasing water temperature (r = -0.717). It is suggested that water temperature is the most important factor in predicting fecal coliform survival from point and nonpoint sources in assessing water quality in an estuarine ecosystem. (+info)Delivery of extraterrestrial amino acids to the primitive Earth. Exposure experiments in Earth orbit. (2/98)
A large collection of micrometeorites has been recently extracted from Antarctic old blue ice. In the 50 to 100 micrometers size range, the carbonaceous micrometeorites represent 80% of the samples and contain 2% of carbon. They might have brought more carbon to the surface of the primitive Earth than that involved in the present surficial biomass. Amino acids such as "-amino isobutyric acid have been identified in these Antarctic micrometeorites. Enantiomeric excesses of L-amino acids have been detected in the Murchison meteorite. A large fraction of homochiral amino acids might have been delivered to the primitive Earth via meteorites and micrometeorites. Space technology in Earth orbit offers a unique opportunity to study the behaviour of amino acids required for the development of primitive life when they are exposed to space conditions, either free or associated with tiny mineral grains mimicking the micrometeorites. Our objectives are to demonstrate that porous mineral material protects amino acids in space from photolysis and racemization (the conversion of L-amino acids into a mixture of L- and D-molecules) and to test whether photosensitive amino acids derivatives can polymerize in mineral grains under space conditions. The results obtained in BIOPAN-1 and BIOPAN-2 exposure experiments on board unmanned satellite FOTON are presented. (+info)Stability of respiratory syncytial virus in a new bentonite holding medium. (3/98)
Stability of respiratory syncytial virus was determined in a new bentonite holding medium and compared with two other commonly used media. Eventual infectivity titers were similar with all three preparations. (+info)Lucigenin chemiluminescence assay as an adjunctive tool for assessment of various stages of inflammation: a study of quiescent inflammatory cells. (4/98)
A simple, fast, precise and biologically relevant toxicity assay for screening cytotoxicity of minerals would have distinct advantages due to its cost benefits and relative savings in time. Furthermore, a bioassay to differentiate acute and chronic in vivo pulmonary reactions could have potential value as predictors of fibrogenicity and pathogenicity. In this study we examined the potential use of lucigenin as a probe to evaluate the correlation between chemiluminescence (CL) generated by alveolar macrophages with the known cytotoxicity and patho genicity by conventional bioassays. In this study, we used small doses of dust (20 microg) to minimize cellular overload and to maintain homeostasis. Crystalline silica a highly fibrogenic dust was used as positive control and results are compared with those for bentonite, kaolin and talc. Among the three minerals compared with silica, bentonite was more reactive (27%) in CL assay and declined sharply compared to other minerals. This sudden decline in bentonite CL is caused by cytotoxicity leading to cell death. CL-induced by talc was comparable to silica and declines slowly. Kaolin on the other hand produced relatively a weaker (25%) CL compared to silica. Our data using relatively low doses of dust suggest that the CL assay may have a better predictive value in cytotoxicity evaluations compared to conventional toxicity assays. (+info)Desorption techniques for determination of metals mobility in soils. (5/98)
Three leaching techniques for assessment of fixed and mobile metal or radionuclides in soils are demonstrated on radiocaesium speciation. A new leaching technique based on the variation of the leaching solution volume to solid phase amount is proposed. It enables parallel treatment of large numbers of samples and, therefore, is suitable for a routine analysis of contaminant mobility in soils. As a leaching solution, 1 M ammonium acetate is proposed for caesium, but any other desorption solution harmonised with existing speciation schemes can be used. (+info)Activity of free and clay-bound insecticidal proteins from Bacillus thuringiensis subsp. israelensis against the mosquito Culex pipiens. (6/98)
Bacillus thuringiensis subsp. israelensis produces parasporal insecticidal crystal proteins (ICPs) that have larvicidal activity against some members of the order Diptera, such as blackflies and mosquitoes. Hydrolysis of the ICPs in the larval gut results in four major proteins with a molecular mass of 27, 65, 128, and 135 kDa. Toxicity is caused by synergistic interaction between the 25-kDa protein (proteolytic product of the 27-kDa protein) and one or more of the higher-molecular-mass proteins. Equilibrium adsorption of the proteins on the clay minerals montmorillonite and kaolinite, which are homoionic to various cations, was rapid (<30 min for maximal adsorption), increased with protein concentration and then reached a plateau (68 to 96% of the proteins was adsorbed), was significantly lower on kaolinite than on montmorillonite, and was not significantly affected by the valence of the cation to which the clays were homoionic. Binding of the toxins decreased as the pH was increased from 6 to 11, and there was 35 to 66% more binding in phosphate buffer at pH 6 than in distilled water at pH 6 or 7.2. Only 2 to 12% of the adsorbed proteins was desorbed by two washes with water; additional washings desorbed no more toxins, indicating that they were tightly bound. Formation of clay-toxin complexes did not alter the structure of the proteins, as indicated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the equilibrium supernatants and desorption washes and by dot blot enzyme-linked immunosorbent assay of the complexes, which was confirmed by enhanced chemiluminescence Western blot analysis. Free and clay-bound toxins resulted in 85 to 100% mortality of the mosquito Culex pipiens. Persistence of the bound toxins in nonsterile water after 45 days was significantly greater (mortality of 63% +/- 12.7%) than that of the free toxins (mortality of 25% +/- 12.5%). (+info)Non-enzymatic oligomerization of racemic adenosine 5'-phosphorimidazolide on Na(+)-montmorillonite. (7/98)
In this study, we have investigated non-enzymatic oligomerization of an activated racemic mononucleotide in the presence of Na(+)-montmorillonite. Oligomers up to the decamer in length were formed by oligomerization reactions of activated D- and L-mononucleotides. Similarly, oligomerization of an activated racemic mononucleotide results in the formation of oligomers up to the octamer. These results suggest that montmorillonite catalysis is quite efficient for the oligomerization of racemic monomers, though it is somewhat less efficient than that of D- and L-monomers. (+info)Effects of bentonite on wool growth and nitrogen metabolism in fauna-free and faunated sheep. (8/98)
Two experiments were carried out with sheep that originated from a fauna-free flock and were fed a soybean meal-corn silage diet with or without a bentonite supplement. One-half of the sheep fed each diet in each experiment were faunated with a mixed population of ruminal protozoa, whereas the other half of the sheep remained fauna-free until the end of both experiments. Wool growth and daily gain were measured in Exp. 1. (eight rams per treatment), which lasted 110 d, and the metabolic effects in the rumen and intestinal tract of protozoa and dietary bentonite supplement were tested with cannulated wethers (four wethers per treatment) in Exp. 2. The results of Exp. 1 showed decreased wool growth (P less than .05) due to the presence of protozoa in the rumen. Dietary supplementation with bentonite partly offset the decreased wool growth in sheep with protozoa, but there were no effects of dietary bentonite and no protozoa x bentonite interaction (P greater than .05). Daily gain was decreased by the dietary bentonite (P less than .05) supplement but was not affected (P greater than .05) by the ruminal presence of protozoa. In Exp. 2, protozoa increased (P less than .01) the ruminal concentrations of ammonia and decreased (P less than .05) the acetic:propionic acid molar ratio. Fractionation of N in the duodenal digesta flowing from the stomach to the small intestine showed that protozoa decreased (P less than .05) the flow of nonammonia N and bacterial N, and there was a protozoa x bentonite interaction for these effects (P less than .05).(ABSTRACT TRUNCATED AT 250 WORDS) (+info)Bentonite is a type of clay mineral that is sometimes used in medical applications, such as wound dressings and as a adsorbent for toxins.
Bentonite is a type of clay that is commonly used in the medical field for a variety of purposes. It is a natural clay that is formed from volcanic ash and is rich in minerals such as silica, aluminum, and iron. Bentonite has a high adsorption capacity, which means that it can absorb and hold onto other substances, including toxins and heavy metals. In the medical field, bentonite is often used as a detoxifying agent to help remove toxins and heavy metals from the body. It is sometimes used in conjunction with other detoxifying agents, such as activated charcoal, to enhance its effectiveness. Bentonite is also sometimes used as a binding agent to help bind together other substances in the body, such as medications or supplements. Bentonite is available in various forms, including powders, capsules, and suppositories. It is typically taken orally, although it can also be applied topically to the skin or used in enemas. It is important to note that bentonite should not be used as a substitute for medical treatment and should only be used under the guidance of a healthcare professional.
Plant poisoning occurs when a person or animal ingests or comes into contact with toxic substances found in plants, leading to various symptoms and potential health complications.
Plant poisoning, also known as phytotoxicity, is a condition that occurs when a person or animal ingests or comes into contact with a toxic substance found in plants. The toxic substances can be present in the plant's leaves, roots, seeds, or fruits, and can cause a range of symptoms depending on the type and amount of the substance ingested. Plant poisoning can be acute or chronic, and the symptoms can range from mild to severe. Acute plant poisoning typically occurs within a few hours to a few days after exposure, and can cause symptoms such as nausea, vomiting, diarrhea, abdominal pain, dizziness, headache, and difficulty breathing. Chronic plant poisoning occurs over a longer period of time and can cause more serious symptoms such as liver or kidney damage, neurological problems, and even death. The treatment for plant poisoning depends on the type and severity of the poisoning. In some cases, the person or animal may need to be hospitalized and treated with medications to remove the toxic substance from their system. In other cases, supportive care such as fluid replacement and symptom management may be sufficient. It is important to note that not all plants are toxic, and some plants can even be beneficial for human health. However, it is always best to exercise caution when handling or ingesting unfamiliar plants, and to seek medical attention if you suspect that you or someone else may have been poisoned by a plant.
Terphenyl compounds are organic molecules consisting of three phenyl rings bonded together, which have potential applications in the medical field as antioxidants, anti-inflammatory agents, and cancer therapeutics.
In the medical field, terphenyl compounds are a class of organic compounds that contain three benzene rings connected together. These compounds are typically used as intermediates in the synthesis of other organic compounds, such as pharmaceuticals and dyes. Some terphenyl compounds have also been studied for their potential therapeutic effects, including anti-inflammatory, anti-cancer, and anti-viral properties. However, more research is needed to fully understand their potential medical applications.
Zeolites are hydrated aluminosilicate minerals that have been used in the medical field as adsorbents, ion-exchangers, and drug delivery systems.
Zeolites are naturally occurring or synthetic microporous aluminosilicate minerals that have a unique three-dimensional structure with interconnected channels and cavities. In the medical field, zeolites are used as adsorbents, which means they can bind to and remove certain substances from the body. One of the most common uses of zeolites in medicine is as a dietary supplement for detoxification. Zeolites are believed to bind to toxins, heavy metals, and other harmful substances in the body and help eliminate them through the digestive system. Some studies have suggested that zeolites may be effective in reducing symptoms of certain conditions, such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), although more research is needed to confirm these findings. Zeolites are also used in some medical treatments, such as in the treatment of certain types of cancer. Zeolites have been shown to have anti-cancer properties and may help to slow the growth of cancer cells or even cause them to die. However, more research is needed to fully understand the potential benefits and risks of using zeolites in cancer treatment. It is important to note that the use of zeolites as a dietary supplement or in medical treatments should only be done under the guidance of a healthcare professional. Zeolites can interact with certain medications and may not be safe for everyone to use.
T-2 Toxin is a mycotoxin produced by certain fungi that can cause illness and death in humans and animals if ingested.
T-2 Toxin is a type of mycotoxin produced by certain species of fungi, including Fusarium and Aspergillus. It is commonly found in cereals, grains, and other agricultural products, and can cause a range of health problems in humans and animals if ingested in sufficient quantities. In the medical field, T-2 Toxin is considered a potential hazard to human health, particularly in cases of food poisoning. It can cause a variety of symptoms, including nausea, vomiting, diarrhea, abdominal pain, and fever. In severe cases, it can lead to more serious health problems, such as liver and kidney damage, and even death. T-2 Toxin is also a concern in veterinary medicine, as it can cause illness and death in livestock if they consume contaminated feed. In addition, it can have negative effects on the growth and development of animals, as well as on their reproductive systems. To prevent the occurrence of T-2 Toxin poisoning, it is important to properly store and handle agricultural products, and to monitor them for signs of fungal contamination. In cases where contamination is suspected, it may be necessary to remove the contaminated products from the food supply and to take steps to prevent further contamination.
Aluminum silicates are a type of mineral compound that can be used in various medical applications, such as as an antacids or an adsorbent to remove toxins from the body.
In the medical field, aluminum silicates are a type of mineral compound that is commonly used as an antacid and an adsorbent. They work by neutralizing stomach acid and binding to toxins and other substances in the digestive tract, which helps to prevent their absorption into the bloodstream. Aluminum silicates are often used to treat conditions such as heartburn, acid reflux, and indigestion. They are available in a variety of forms, including tablets, capsules, and powders, and can be taken orally or used topically. It is important to note that while aluminum silicates are generally considered safe for short-term use, long-term use or high doses may have potential side effects, such as constipation, nausea, and abdominal pain. As with any medication, it is important to follow the instructions of your healthcare provider and to report any adverse reactions.
Cetrimonium compounds are a class of quaternary ammonium compounds used in the medical field as antifungal and anti-inflammatory agents, particularly in the treatment of skin conditions.
Cetrimonium compounds are a class of quaternary ammonium compounds that are commonly used in the medical field as antiseptics, preservatives, and skin conditioners. They are typically composed of a quaternary ammonium salt attached to a fatty acid chain, which allows them to interact with and disrupt the lipid bilayer of bacterial cell membranes, leading to cell death. Cetrimonium compounds are often used in shampoos, conditioners, and other personal care products to help prevent scalp infections and dandruff. They are also used in some topical antiseptic products to help kill bacteria and prevent the spread of infection. In addition, cetrimonium compounds have been shown to have anti-inflammatory and anti-irritant properties, which may make them useful in the treatment of skin conditions such as eczema and psoriasis. It is important to note that while cetrimonium compounds are generally considered safe and well-tolerated, they can cause skin irritation or allergic reactions in some people. As with any product, it is always a good idea to patch test a small area of skin before using a new cetrimonium-containing product to check for any potential adverse reactions.
Swainsonine is a toxic amino acid derivative found in certain plants that can cause liver damage and other health problems in animals and humans who consume them.
Swainsonine is a toxic amino acid derivative that is produced by certain species of fungi, including the ergot fungus (Claviceps purpurea). It is named after the English botanist William Swainson, who first described the fungus in the early 19th century. In the medical field, swainsonine is known for its ability to inhibit the activity of eukaryotic initiation factor 2B (eIF2B), a key enzyme involved in protein synthesis. This inhibition leads to the accumulation of unprocessed proteins in the cell, which can cause a range of toxic effects, including cell death. Swainsonine has been studied for its potential as an antifungal agent, as well as for its potential use in cancer therapy. It has been shown to selectively kill certain types of cancer cells, including those that are resistant to other forms of chemotherapy. However, swainsonine is also toxic to normal cells, and its use in humans is limited by its potential for side effects.
Carboxylesterase is an enzyme that breaks down ester bonds in various molecules, including drugs and toxins, in the body.
Carboxylesterase is an enzyme that catalyzes the hydrolysis of carboxylic esters. In the medical field, carboxylesterases are important in the metabolism of a variety of drugs and toxins, including anesthetics, barbiturates, and certain pesticides. They are also involved in the breakdown of fatty acids and cholesterol in the body. Deficiency or dysfunction of carboxylesterases can lead to a variety of health problems, including drug toxicity and metabolic disorders.
Toxoids are inactivated or weakened forms of toxins used as vaccines to prevent infectious diseases caused by bacteria.
In the medical field, "toxoids" refer to vaccines or immunizing agents that are made from inactivated or weakened forms of toxins produced by bacteria or other microorganisms. These toxins are usually produced by the same microorganisms that cause diseases, such as diphtheria, tetanus, and pertussis. Toxoids are used to stimulate the immune system to produce antibodies against the toxins, which can then protect against the disease caused by the microorganism. They are often used in combination with other vaccines to provide comprehensive protection against a range of diseases. Toxoids are considered safe and effective, and are widely used in vaccination programs around the world. They are typically administered through injection, and can be given to people of all ages, including infants and children.
