Respiratory epithelial cells demonstrate lactoferrin receptors that increase after metal exposure. (1/74)

Human airway epithelial cells can increase expression of both lactoferrin and ferritin after exposure to catalytically active metal. These proteins transport and store metal, with coordination sites fully complexed, and therefore can diminish the oxidative stress. The intracellular transport of lactoferrin results in a transfer of complexed metal to ferritin, where it is stored in a less reactive form. This effort to control the injurious properties of metals would be facilitated by lactoferrin receptors (LfRs) on airway epithelial cells. We tested the hypotheses that 1) LfRs exist on respiratory epithelial cells and 2) exposure to both an air pollution particle, which has abundant concentrations of metals, and individual metal salts increase the expression of LfRs. Before exposure to either the particle or metals, incubation of BEAS-2B cells with varying concentrations of 125I-labeled lactoferrin demonstrated lactoferrin binding that was saturable. Measurement of 125I-lactoferrin binding after the inclusion of 100 micrograms/ml of oil fly ash in the incubation medium demonstrated increased binding within 5 min of exposure, which reached a maximal value at 45 min. Inclusion of 1.0 mM deferoxamine in the incubation of BEAS-2B cells with 100 micrograms/ml of oil fly ash decreased lactoferrin binding. Comparable to the particle, exposure of BEAS-2B cells to either 1.0 mM vanadyl sulfate or 1.0 mM iron (III) sulfate, but not to nickel sulfate, for 45 min elevated LfR activity. We conclude that LfRs on respiratory epithelial cells increased after exposure to metal. LfRs could participate in decreasing the oxidative stress presented to the lower respiratory tract by complexing catalytically active metals.  (+info)

Role of soluble metals in oil fly ash-induced airway epithelial injury and cytokine gene expression. (2/74)

Particulate matter (PM) metal content and bioavailability have been hypothesized to play a role in the health effects epidemiologically associated with PM exposure, in particular that associated with emission source PM. Using rat tracheal epithelial cells in primary culture, the present study compared and contrasted the acute airway epithelial effects of an emission source particle, residual oil fly ash (ROFA), with that of its principal constitutive transition metals, namely iron, nickel, and vanadium. Over a 24-h period, exposure to ROFA, vanadium, or nickel plus vanadium, but not to iron or nickel, resulted in increased epithelial permeability, decreased cellular glutathione, cell detachment, and lytic cell injury. Treatment of vanadium-exposed cells with buthionine sulfoximine further increased cytotoxicity. Conversely, treatment with the radical scavenger dimethylthiourea inhibited the effects in a dose-dependent manner. RT-PCR analysis of RNA isolated from ROFA-exposed rat tracheal epithelial cells demonstrated significant macrophage inflammatory protein-2 and interleukin-6 gene expression as early as 6 h after exposure, whereas gene expression of inducible nitric oxide synthase was maximally increased 24 h postexposure. Again, vanadium (not nickel) appeared to be mediating the effects of ROFA on gene expression. Treatment with dimethylthiourea inhibited both ROFA- and vanadium-induced gene expression in a dose-dependent manner. Corresponding effects were observed in interleukin-6 and macrophage inflammatory protein-2 synthesis. In summary, generation of an oxidative stress was critical to induction of the ROFA- or vanadium-induced effects on airway epithelial gene expression, cytokine production, and cytotoxicity.  (+info)

Residual oil fly ash and charged polymers activate epithelial cells and nociceptive sensory neurons. (3/74)

Residual oil fly ash (ROFA) is an industrial pollutant that contains metals, acids, and unknown materials complexed to a particulate core. The heterogeneous composition of ROFA hampers finding the mechanism(s) by which it and other particulate pollutants cause airway toxicity. To distinguish culpable factors contributing to the effects of ROFA, synthetic polymer microsphere (SPM) analogs were synthesized that resembled ROFA in particle size (2 and 6 microm in diameter) and zeta potential (-29 mV). BEAS-2B human bronchial epithelial cells and dorsal root ganglion neurons responded to both ROFA and charged SPMs with an increase in intracellular Ca(2+) concentration ([Ca(2+)](i)) and the release of the proinflammatory cytokine interleukin-6, whereas neutral SPMs bound with polyethylene glycol (0-mV zeta potential) were relatively ineffective. In dorsal root ganglion neurons, the SPM-induced increases in [Ca(2+)](i) were correlated with the presence of acid- and/or capsaicin-sensitive pathways. We hypothesized that the acidic microenvironment associated with negatively charged colloids like ROFA and SPMs activate irritant receptors in airway target cells. This causes subsequent cytokine release, which mediates the pathophysiology of neurogenic airway inflammation.  (+info)

Variable pulmonary responses from exposure to concentrated ambient air particles in a rat model of bronchitis. (4/74)

Chronic bronchitis may be considered a risk factor in particulate matter (PM)-induced morbidity. We hypothesized that a rat model of human bronchitis would be more susceptible to the pulmonary effects of concentrated ambient particles (CAPs) from Research Triangle Park, NC. Bronchitis was induced in male Sprague-Dawley rats (90-100 days of age) by exposure to 200 ppm sulfur dioxide (SO2), 6 h/day x 5 days/week x 6 weeks. One day following the last SO2 exposure, both healthy (air-exposed) and bronchitic (SO2-exposed) rats were exposed to filtered air (three healthy; four bronchitic) or CAPs (five healthy; four bronchitic) by whole-body inhalation, 6 h/day x 2 or 3 days. Pulmonary injury was determined either immediately (0h) or 18 h following final CAPs exposure. The study protocol involving 0 h time point was repeated four times (study #A, November, 1997; #B, February, 1998; #C and #D, May, 1998), whereas the study protocol involving 18 h time point was done only once (#F). In an additional study (#E), rats were exposed to residual oil fly ash (ROFA), approximately 1 mg/ m(3)x6 h/day x 3 days to mimic the CAPs protocol (February, 1998). The rats allowed 18 h recovery following CAPs exposure (#F) did not depict any CAPs-related differences in bronchoalveolar lavage fluid (BALF) injury markers. Of the four CAPs studies conducted (0 h time point), the first (#A) study (approximately 650 microg/m3 CAPs) revealed significant changes in the lungs of CAPs-exposed bronchitic rats compared to the clean air controls. These rats had increased BALF protein, albumin, N-acetyl glutaminidase (NAG) activity and neutrophils. The second (#B) study (approximately 475 microg/m3 CAPs) did not reveal any significant effects of CAPs on BALF parameters. Study protocols #C (approximately 869 microg/m3 CAPs) and #D (approximately 907 microg/m3 CAPs) revealed only moderate increases in the above mentioned BALF parameters in bronchitic rats exposed to CAPs. Pulmonary histologic evaluation of studies #A, #C, #D, and #F revealed marginally higher congestion and perivascular cellularity in CAPs-exposed bronchitic rats. Healthy and bronchitic rats exposed to ROFA (approximately 1 mg/m3) did not show significant pulmonary injury (#E). Analysis of leachable elemental components of CAPs revealed the presence of sulfur, zinc, manganese, and iron. There was an apparent lack of association between pulmonary injury and CAPs concentration, or its leachable sulfate or elemental content. In summary, real-time atmospheric PM may result in pulmonary injury, particularly in susceptible models. However, the variability observed in pulmonary responses to CAPs emphasizes the need to conduct repeated studies, perhaps in relation to the season, as composition of CAPs may vary. Additionally, potential variability in pathology of induced bronchitis or other lung disease may decrease the ability to distinguish toxic injury due to PM.  (+info)

Diminished injury in hypotransferrinemic mice after exposure to a metal-rich particle. (5/74)

Using the hypotransferrinemic (Hp) mouse model, we studied the effect of altered iron homeostasis on the defense of the lung against a catalytically active metal. The homozygotic (hpx/hpx) Hp mice had greatly diminished concentrations of both serum and lavage fluid transferrin relative to wild-type mice and heterozygotes. Fifty micrograms of a particle containing abundant concentrations of metals (a residual oil fly ash) was instilled into wild-type mice and heterozygotic and homozygotic Hp animals. There was an oxidative stress associated with particle exposure as manifested by decreased lavage fluid concentrations of ascorbate. However, rather than an increase in lung injury, diminished transferrin concentrations in homozygotic Hp mice were associated with decreased indexes of damage, including concentrations of relevant cytokines, inflammatory cell influx, lavage fluid protein, and lavage fluid lactate dehydrogenase. Comparable to other organs in the homozygotic Hp mouse, siderosis of the lung was evident, with elevated concentrations of lavage fluid and tissue iron. Consequent to these increased concentrations of iron, proteins to store and transport iron, ferritin, and lactoferrin, respectively, were increased when assayed by immunoprecipitation and immunohistochemistry. We conclude that the lack of transferrin in Hp mice did not predispose the animals to lung injury after exposure to a particle abundant in metals. Rather, these mice demonstrated a diminished injury that was associated with an increase in the metal storage and transport proteins.  (+info)

Oil fly ash-induced elevation of plasma fibrinogen levels in rats. (6/74)

Particulate matter air pollution (PM) has been associated with morbidity and mortality from ischemic heart disease and stroke in humans. It has been hypothesized that alveolar inflammation, resulting from exposure to PM, may induce a state of blood hypercoagulability, triggering cardiovascular events in susceptible individuals. Previous studies in our laboratory have demonstrated acute lung injury with alveolar inflammation in rats following exposure to residual oil fly ash (ROFA), an emission source particulate. In addition, increased mortality has been documented following exposure to ROFA in rats with preexistent cardiopulmonary disease. ROFA's toxicity derives from its soluble metal content, which appears also to drive the toxicity of ambient PM. The present study was conducted to test the hypothesis that exposure of rats to a toxic PM, like ROFA, would adversely alter hemostatic parameters and cardiovascular risk factors thought to be involved in human epidemiologic findings. Sixty-day-old male Sprague-Dawley rats were exposed by intratracheal instillation (IT) to varying doses (0.3, 1. 7, or 8.3 mg/kg) of ROFA, 8.3 mg/kg Mt. Saint Helen's volcanic ash (MSH, control particle), or 0.3 ml saline (SAL, control). At 24 h post-IT, activated partial thromboplastin time (APTT), prothrombin time (PT), plasma fibrinogen (PF), plasma viscosity (PV), and complete blood count (CBC) were performed on venous blood samples. No differences from control were detected in APTT and PT in ROFA-exposed rats; however, ROFA exposure did result in elevated PF, at 8.3 mg/kg only. In addition, PV values were elevated in both ROFA and MSH-exposed rats relative to SAL-control rats, but not significantly. Although no changes were detected in APTT and PT, alteration of important hematologic parameters (notably fibrinogen) through PM induction of an inflammatory response may serve as biomarkers of cardiovascular risk in susceptible individuals.  (+info)

Induction of pulmonary matrilysin expression by combustion and ambient air particles. (7/74)

The molecular mechanism(s) by which chemically complex air pollution particles mediate their adverse health effects is not known. We have examined the ability of combustion and ambient air particles to induce pulmonary matrilysin expression due to the well-documented role of matrix metalloproteinases in tissue injury and repair responses. Rats were exposed to saline, residual oil fly ash (2.5 mg/rat), or ambient air particles (2.5 mg/rat) via intratracheal instillation and examined 3-72 h after exposure. Saline-exposed animals had low levels of matrilysin mRNA, whereas the animals exposed to either complex particle showed an early induction of pulmonary matrilysin gene expression as well as of the 19-kDa activated form of matrilysin. Immunocytochemistry and in situ hybridization analyses identified the alveolar macrophages and monocytes as primary sources of air pollution particle-induced matrilysin expression. Matrilysin gene induction and protein activation by combustion and ambient air particles correlated with the early histopathological changes produced by these particles. These results demonstrate the ability of combustion and ambient air particles to induce pulmonary matrilysin expression and suggest a role for this matrix metalloproteinase in the initiation of lung injury produced by these particles.  (+info)

The Indian Ocean experiment: widespread air pollution from South and Southeast Asia. (8/74)

The Indian Ocean Experiment (INDOEX) was an international, multiplatform field campaign to measure long-range transport of air pollution from South and Southeast Asia toward the Indian Ocean during the dry monsoon season in January to March 1999. Surprisingly high pollution levels were observed over the entire northern Indian Ocean toward the Intertropical Convergence Zone at about 6 degrees S. We show that agricultural burning and especially biofuel use enhance carbon monoxide concentrations. Fossil fuel combustion and biomass burning cause a high aerosol loading. The growing pollution in this region gives rise to extensive air quality degradation with local, regional, and global implications, including a reduction of the oxidizing power of the atmosphere.  (+info)

In the medical field, waste products refer to any materials or substances that are generated during the course of medical treatment or research and are considered to be no longer useful or safe to handle. These waste products can include a wide range of materials, such as used needles, syringes, gloves, gowns, bandages, catheters, and other medical equipment and supplies. Waste products can be classified into different categories based on their potential hazards and the methods required for their safe disposal. For example, infectious waste, which may contain pathogens that can cause disease, must be handled and disposed of differently than non-infectious waste. Proper management and disposal of medical waste is essential to prevent the spread of disease, protect the environment, and ensure the safety of healthcare workers and patients. Healthcare facilities must follow strict guidelines and regulations for the collection, storage, transportation, and disposal of medical waste.

I'm sorry, but I cannot find any medical definition for "Coal Ash." Coal ash is a waste product generated during the combustion of coal, and it is typically not used in the medical field. However, coal ash can contain harmful substances such as heavy metals and radioactive materials, and exposure to it can have negative health effects. If you have any concerns about your exposure to coal ash or its potential health effects, I would recommend consulting with a healthcare professional.

I'm sorry, but I couldn't find any medical definition of "coal." Coal is a fossil fuel that is primarily used for energy production, but it is not typically used in the medical field. If you have any other questions, please let me know.

Coal tar is a dark, viscous liquid that is produced as a byproduct of the distillation of coal. It has been used in the medical field for centuries to treat a variety of skin conditions, including psoriasis, eczema, and seborrheic dermatitis. Coal tar works by reducing inflammation, slowing down the growth of skin cells, and killing bacteria and fungi that can cause skin infections. It is typically applied topically to the affected area, either as a cream, ointment, or shampoo. While coal tar can be effective in treating skin conditions, it can also cause side effects such as skin irritation, dryness, and discoloration. It is important to follow the instructions for use carefully and to consult a healthcare provider if you experience any adverse reactions.

Pneumoconiosis is a group of lung diseases caused by the inhalation of dust particles that are small enough to be breathed deep into the lungs. These dust particles can be made up of a variety of materials, including coal, silica, asbestos, and other minerals. Over time, the dust particles can accumulate in the lungs and cause inflammation, scarring, and other damage to the lung tissue. This can lead to a range of symptoms, including shortness of breath, coughing, and chest pain. Pneumoconiosis can be a serious and potentially life-threatening condition, and it is important for people who work in industries that involve exposure to dust particles to take steps to protect themselves from the risk of developing this disease.

Anthracosis is a type of lung disease caused by the inhalation of coal dust or other types of particulate matter. It is characterized by the accumulation of black, coal-like material in the lungs, which can lead to inflammation, scarring, and other respiratory problems. The severity of anthracosis can vary depending on the amount and duration of exposure to the dust, as well as the individual's overall health. Treatment for anthracosis typically involves addressing the underlying respiratory symptoms and may include medications, oxygen therapy, and pulmonary rehabilitation. In severe cases, surgery may be necessary to remove damaged lung tissue.

In the medical field, dust refers to a mixture of small particles that are suspended in the air. These particles can come from a variety of sources, including soil, pollen, pet dander, and human skin cells. Dust can be inhaled and can cause a range of health problems, including respiratory issues such as asthma, bronchitis, and pneumonia. It can also cause irritation of the eyes, nose, and throat, and can exacerbate existing conditions such as allergies and eczema. In some cases, exposure to certain types of dust can be hazardous, such as asbestos or silica dust, which can cause serious health problems if inhaled in large quantities.

In the medical field, "quartz" typically refers to a type of mineral that is commonly used in the production of medical devices and instruments. Quartz is a hard, crystalline mineral that is composed of silicon dioxide (SiO2) and is known for its high refractive index, which makes it useful for producing lenses and other optical components. Quartz is often used in the production of medical devices such as microscopes, spectrometers, and lasers. It is also used in the manufacture of surgical instruments, such as scalpels and forceps, due to its durability and resistance to corrosion. In addition to its use in medical devices, quartz is also used in the production of certain types of medical implants, such as dental fillings and orthopedic implants. However, it is important to note that the use of quartz in medical implants is relatively uncommon, and other materials such as titanium and stainless steel are more commonly used for this purpose.

In the medical field, industrial waste refers to any waste materials generated during the production, processing, or distribution of medical products or services. This can include a wide range of materials, such as packaging materials, contaminated equipment, used needles and syringes, biological waste, and chemical waste. Medical industrial waste is considered hazardous because it can contain infectious agents, toxins, and other harmful substances that can pose a risk to human health and the environment if not properly managed. As a result, medical facilities are required to follow strict regulations and guidelines for the collection, storage, transportation, and disposal of medical industrial waste to ensure that it is handled safely and responsibly.

Anthracosilicosis is a type of lung disease caused by the inhalation of coal dust, which contains a high concentration of silica particles. The disease is characterized by the accumulation of black, coal-like material (anthracosis) and silica particles in the lungs, leading to inflammation, scarring, and the formation of nodules. Symptoms of anthracosilicosis may include coughing, shortness of breath, chest pain, and fatigue. The disease can progress slowly over many years, and can lead to chronic obstructive pulmonary disease (COPD), lung cancer, and other respiratory problems. Anthracosilicosis is most commonly associated with coal mining and other occupations that involve exposure to coal dust. Treatment may include medications to manage symptoms, oxygen therapy, and in severe cases, lung transplantation. Prevention measures include the use of protective equipment, proper ventilation, and regular medical monitoring for workers exposed to coal dust.

In the medical field, polycyclic compounds are organic compounds that consist of two or more fused aromatic rings. These compounds are often found in nature and are known for their complex structures and diverse biological activities. Polycyclic compounds can be classified into several categories based on their structure, including polycyclic aromatic hydrocarbons (PAHs), heterocyclic compounds, and fused-ring systems. PAHs are compounds that contain multiple aromatic rings, typically with a carbon skeleton, and are known for their carcinogenic properties. Heterocyclic compounds contain at least one heteroatom (such as nitrogen, oxygen, or sulfur) in addition to carbon, and are often used as pharmaceuticals or as intermediates in the synthesis of other drugs. Fused-ring systems are compounds that consist of two or more rings that are fused together, and are often used as dyes or pigments. Polycyclic compounds can have a wide range of biological activities, including anti-inflammatory, anti-cancer, and anti-microbial properties. They are also used in the development of new drugs and as research tools to study the mechanisms of various diseases. However, some polycyclic compounds can be toxic or carcinogenic, and their use must be carefully monitored to minimize potential risks.

In the medical field, the term "fossil fuels" is not commonly used. However, it is worth noting that the burning of fossil fuels, such as coal, oil, and natural gas, is a major source of air pollution, which can have negative health effects on humans. Exposure to air pollution has been linked to a variety of health problems, including respiratory diseases, heart disease, and cancer. Therefore, reducing the use of fossil fuels and transitioning to cleaner sources of energy is an important public health concern.

In the medical field, particulate matter (PM) refers to tiny solid or liquid particles that are suspended in the air. These particles can be inhaled into the lungs and can cause a range of health problems, including respiratory and cardiovascular diseases. PM can be classified based on their size, with smaller particles being more harmful to health. PM2.5 refers to particles with a diameter of 2.5 micrometers or less, while PM10 refers to particles with a diameter of 10 micrometers or less. These particles can penetrate deep into the lungs and even enter the bloodstream, causing inflammation and oxidative stress. Exposure to high levels of PM can increase the risk of developing conditions such as asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and heart disease. It can also exacerbate existing health conditions and increase the risk of premature death. In summary, particulate matter is a type of air pollution that can have serious health consequences when inhaled. It is an important consideration in public health and environmental policy, and efforts are being made to reduce its levels in the air.

In the medical field, the term "carbon" typically refers to the chemical element with the atomic number 6, which is a vital component of all living organisms. Carbon is the building block of organic molecules, including proteins, carbohydrates, lipids, and nucleic acids, which are essential for the structure and function of cells and tissues. In medicine, carbon is also used in various diagnostic and therapeutic applications. For example, carbon-13 (13C) is a stable isotope of carbon that is used in metabolic studies to investigate the function of enzymes and pathways in the body. Carbon-14 (14C) is a radioactive isotope of carbon that is used in radiocarbon dating to determine the age of organic materials, including human remains. Additionally, carbon dioxide (CO2) is a gas that is produced by the body during respiration and is exhaled. It is also used in medical applications, such as in carbon dioxide laser therapy, which uses the energy of CO2 lasers to treat various medical conditions, including skin disorders, tumors, and eye diseases.
