Osmotic regulation of airway reactivity by epithelium. (1/123)

Inhalation of nonisotonic solutions can elicit pulmonary obstruction in asthmatic airways. We evaluated the hypothesis that the respiratory epithelium is involved in responses of the airways to nonisotonic solutions using the guinea pig isolated, perfused trachea preparation to restrict applied agents to the mucosal (intraluminal) or serosal (extraluminal) surface of the airway. In methacholine-contracted tracheae, intraluminally applied NaCl or KCl equipotently caused relaxation that was unaffected by the cyclo-oxygenase inhibitor, indomethacin, but was attenuated by removal of the epithelium and Na+ and Cl- channel blockers. Na+-K+-2Cl- cotransporter and nitric oxide synthase blockers caused a slight inhibition of relaxation, whereas Na+,K+-pump inhibition produced a small potentiation. Intraluminal hyperosmolar KCl and NaCl inhibited contractions in response to intra- or extraluminally applied methacholine, as well as neurogenic cholinergic contractions elicited with electric field stimulation (+/- indomethacin). Extraluminally applied NaCl and KCl elicited epithelium-dependent relaxation (which for KCl was followed by contraction). In contrast to the effects of hyperosmolarity, intraluminal hypo-osmolarity caused papaverine-inhibitable contractions (+/- epithelium). These findings suggest that the epithelium is an osmotic sensor which, through the release of epithelium-derived relaxing factor, can regulate airway diameter by modulating smooth muscle responsiveness and excitatory neurotransmission.

Nitric oxide synthesis in patients with infective gastroenteritis. (2/123)

BACKGROUND: There is evidence that endogenous nitrate synthesis is notably increased in patients with infective gastroenteritis. AIMS: To determine whether this is due to nitric oxide (NO) production via the L-arginine/NO pathway. METHODS: Seven male patients with community acquired bacterial gastroenteritis and 15 healthy male volunteers participated in this study. All patients had stool culture positive infective gastroenteritis. A bolus of 200 mg L-[(15)N](2)-arginine was administered intravenously after an overnight fast. Urine was collected for the next 36 hours. Urinary [(15)N:(14)N]nitrate ratio was assessed by dry combustion in an isotope ratio mass spectrometer. RESULTS: Mean 36 hour total urinary nitrate excretion in the gastroenteritis group was 5157 (577) micromol compared with 2594 (234) micromol in the control group (p<0.001). Thirty six hour urinary [(15)N]nitrate excretion was considerably higher in the gastroenteritis group compared with the control group (13782 (1665) versus 1698 (98) etamol; p<0.001). These values represent 1.129 (0.139)% and 0.138 (0.007)% of [(15)N]nitrogen administered (p<0.001), respectively. Corrected 36 hour urinary [(15)N]nitrate excretion for urinary creatinine was also significantly higher in the patient compared with the control group (1934 (221) versus 303 (35) etamol/mmol; p<0.001). CONCLUSION: Results show notably enhanced nitrate synthesis due to increased activity of the L-arginine/NO pathway in patients with infective gastroenteritis. (+info)

Essential roles for the products of the napABCD genes, but not napFGH, in periplasmic nitrate reduction by Escherichia coli K-12. (3/123)

The seven nap genes at minute 47 on the Escherichia coli K-12 chromosome encode a functional nitrate reductase located in the periplasm. The molybdoprotein, NapA, is known to be essential for nitrate reduction. We now demonstrate that the two c-type cytochromes, the periplasmic NapB and the membrane-associated NapC, as well as a fourth polypeptide, NapD, are also essential for nitrate reduction in the periplasm by physiological substrates such as glycerol, formate and glucose. None of the three iron-sulphur proteins, NapF, NapG or NapH, are essential, irrespective of whether the bacteria are grown anaerobically in the presence of nitrate or fumarate as a terminal electron acceptor, or by glucose fermentation. Mutation of napD resulted in the total loss of Methyl Viologen-dependent nitrate reductase activity of the molybdoprotein, NapA, consistent with an earlier suggestion by others that NapD might be required for post-translational modification of NapA.

Competition between Escherichia coli strains expressing either a periplasmic or a membrane-bound nitrate reductase: does Nap confer a selective advantage during nitrate-limited growth? (4/123)

The physiological role of the periplasmic nitrate reductase, Nap, one of the three nitrate reductases synthesized by Escherichia coli K-12, has been investigated. A series of double mutants that express only one nitrate reductase were grown anaerobically in batch cultures with glycerol as the non-fermentable carbon source and nitrate as the terminal electron acceptor. Only the strain expressing nitrate reductase A grew rapidly under these conditions. Introduction of a narL mutation severely decreased the growth rate of the nitrate reductase A strain, but enhanced the growth of the Nap(+) strain. The ability to use nitrate as a terminal electron acceptor for anaerobic growth is therefore regulated primarily by the NarL protein at the level of transcription. Furthermore, the strain expressing nitrate reductase A had a substantial selective advantage in competition with the strain expressing only Nap during nitrate-sufficient continuous culture. However, the strain expressing Nap was preferentially selected during nitrate-limited continuous growth. The saturation constants for nitrate for the two strains (which numerically are equal to the nitrate concentrations at half of the maximum specific growth rate and therefore reflect the relative affinities for nitrate) were estimated using the integrated Monod equation to be 15 and 50 microM for Nap and nitrate reductase A respectively. This difference is sufficient to explain the selective advantage of the Nap(+) strain during nitrate-limited growth. It is concluded that one physiological role of the periplasmic nitrate reductase of enteric bacteria is to enable bacteria to scavenge nitrate in nitrate-limited environments. (+info)

A habitat for psychrophiles in deep Antarctic ice. (5/123)

Microbes, some of which may be viable, have been found in ice cores drilled at Vostok Station at depths down to approximately 3,600 m, close to the surface of the huge subglacial Lake Vostok. Two types of ice have been found. The upper 3,500 m comprises glacial ice containing traces of nutrients of aeolian origin including sulfuric acid, nitric acid, methanosulfonic acid (MSA), formic acid, sea salts, and mineral grains. Ice below approximately 3,500 m comprises refrozen water from Lake Vostok, accreted to the bottom of the glacial ice. Nutrients in the accretion ice include salts and dissolved organic carbon. There is great interest in searching for living microbes and especially for new species in deepest Antarctic ice. I propose a habitat consisting of interconnected liquid veins along three-grain boundaries in ice in which psychrophilic bacteria can move and obtain energy and carbon from ions in solution. In the accretion ice, with an age of a few 10(4) years and a temperature a few degrees below freezing, the carbon and energy sources in the veins can maintain significant numbers of cells per cubic centimeter that are metabolizing but not multiplying. In the 4 x 10(5)-year-old colder glacial ice, at least 1 cell per cm(3) in acid veins can be maintained. With fluorescence microscopy tuned to detect NADH in live organisms, motile bacteria could be detected by direct scanning of the veins in ice samples. (+info)

Vasopressin does not effect hypertension caused by long-term nitric oxide inhibition. (6/123)

Nitric oxide attenuates both vasopressin-induced vasoconstriction and vasopressin release. We tested whether hypertension and renal dysfunction elicited by chronic inhibition of nitric oxide (NO) synthesis using N(G)-nitro-L-arginine (L-NNA) could be mediated in part by vasopressin V(1A) receptors. Male rats were treated orally for 6 weeks with L-NNA (15 mg/kg per day), a nonpeptide V(1A) receptor antagonist (2S)-1-[(2R,3S)-5-chloro-3-(2-chlorophenyl)-1-(3, 4-dimethoxybenzene-sulfonyl)-3-hydroxy-2, 3-dihydro-1H-indole-2-carbonyl]-pyrrolidine-2-carboxamide (SR 49059, 30 mg/kg per day), or a combination of SR 49059 and L-NNA (same doses), or they received no treatment. Both drugs were added to the food. Measurements were performed in conscious rats (urine collection in metabolic cages, tail-cuff arterial pressure) and at the end of the study in anesthetized rats (clearance measurements). L-NNA produced sustained hypertension, decreased glomerular filtration rate, and increased renal vascular resistance, plasma renin activity, and urinary albumin excretion. SR 49059 had no effect per se on these parameters and also did not attenuate the hypertension and renal dysfunction induced by L-NNA. Surprisingly, SR 49059 potentiated L-NNA-induced hypertension at the end of the 6-week treatment. However, the blood pressure response and the renal and mesenteric vasoconstriction elicited by exogenous vasopressin were attenuated in rats treated with SR 49059. L-NNA did not change plasma vasopressin concentration or 24-hour urinary vasopressin excretion. Our findings suggest that activation of vasopressin V(1A) receptors does not contribute to the hypertension and renal dysfunction induced by chronic NO synthesis inhibition. They also document unchanged plasma vasopressin concentration in NO-deficient hypertension. (+info)

Effects of Ca(2+) channel activity on renal hemodynamics during acute attenuation of NO synthesis in the rat. (7/123)

In cultured vascular muscle cells, nitric oxide (NO) has been shown to inhibit voltage-dependent Ca(2+) channels, which are involved in renal blood flow (RBF) autoregulation. Therefore, our purpose was to specify in vivo the effects of this interaction on RBF autoregulation. To do so, hemodynamics were investigated in anesthetized rats during Ca(2+) channel blockade before or after acute NO synthesis inhibition. Rats were treated intravenously with vehicle (n = 10), 0.3 mg/kg body wt N(G)-nitro-L-arginine-methyl ester (L-NAME; n = 7), 4.5 microg. kg body wt(-1). min(-1) nifedipine (n = 8) alone, or with nifedipine infused before (n = 8), after (n = 8), or coadministered with L-NAME (n = 10). Baseline renal vascular resistance (RVR) averaged 14.0 +/- 1.2 resistance units and did not change after vehicle. RVR increased or decreased significantly by 27 and 29% after L-NAME or nifedipine, respectively. Nifedipine reversed, but did not prevent, RVR increase after or coadministered with L-NAME. RBF autoregulation was maintained after L-NAME, but the autoregulatory pressure limit (P(A)) was significantly lowered by 15 mmHg. Nifedipine pretreatment or coadministration with L-NAME limited P(A) resetting or suppressed autoregulation at higher doses. Results were similar with verapamil. Intrarenal blockade of Ca(2+)-activated K(+) channels also prevented autoregulatory resetting by L-NAME (n = 8). These findings suggest NO inhibits voltage-dependent Ca(2+) channels and thereby modulates RBF autoregulatory efficiency. (+info)

Possible involvement of undissociated acid molecules in the acid response of the chorda tympani nerve of the rat. (8/123)

To test whether undissociated acid is capable of exciting the chorda tympani nerves in rats, we have used buffered acid solutions as taste stimuli. These solutions were prepared by adding alkali to weak acids, such as acetic acid, so that the proportion of undissociated and dissociated acids was varied whereas keeping the total acid concentration constant. When acetic acid solutions, adjusted to wide ranges of pH by NaOH, were applied to the tongue, the response magnitude of the chorda tympani nerves was not varied systematically with pH changes. However, if the sodium effect was eliminated by amiloride or replacement of cation by potassium or Tris[hydroxymethyl]aminomethane; NH(2)C(CH(2)OH)(3) (Tris-base), the chorda tympani response was reduced systematically as pH increased. Similar results were obtained with citric acid and ascorbic acid. This pH-dependent change in taste nerve response to acid cannot be solely attributed to the proton gradient because the response magnitude induced by hydrogen itself, which was estimated from responses to strong acids, was much smaller than that by equi-pH acetic acid ( approximately 85%). Thus we cannot explain the pH-dependent responses of the chorda tympani nerves to weak acids unless effects of undissociated acid molecules are postulated. It is therefore concluded that undissociated acids in weak acid solutions can be a stimulant to taste receptor cells. (+info)

Nitric acid is not a medical term, but it is a chemical compound with the formula HNO3. It is a highly corrosive mineral acid and is the primary constituent of nitric acid solutions.

Medically, nitric acid or its salts may be mentioned in the context of certain medical conditions or treatments. For example, nitrate or nitrite salts of potassium or sodium can be used as vasodilators to treat angina pectoris (chest pain) by improving blood flow and reducing oxygen demand in the heart muscle. Nitric acid itself is not used medically.

It's important to note that exposure to nitric acid can cause severe burns and tissue damage, so it should be handled with care and appropriate personal protective equipment.

Atomic spectrophotometry is a type of analytical technique used to determine the concentration of specific atoms or ions in a sample by measuring the intensity of light absorbed or emitted at wavelengths characteristic of those atoms or ions. This technique involves the use of an atomic spectrometer, which uses a source of energy (such as a flame, plasma, or electrode) to excite the atoms or ions in the sample, causing them to emit light at specific wavelengths. The intensity of this emitted light is then measured and used to calculate the concentration of the element of interest.

Atomic spectrophotometry can be further divided into two main categories: atomic absorption spectrophotometry (AAS) and atomic emission spectrophotometry (AES). In AAS, the sample is atomized in a flame or graphite furnace and the light from a lamp that emits light at the same wavelength as one of the elements in the sample is passed through the atoms. The amount of light absorbed by the atoms is then measured and used to determine the concentration of the element. In AES, the sample is atomized and excited to emit its own light, which is then measured and analyzed to determine the concentration of the element.

Atomic spectrophotometry is widely used in various fields such as environmental monitoring, clinical chemistry, forensic science, and industrial quality control for the determination of trace elements in a variety of sample types including liquids, solids, and gases.

I'm sorry for any confusion, but "Neodymium" is not a medical term. It is a chemical element with the symbol Nd and atomic number 60. Neodymium is a rare-earth metal that has been used in various industrial and technological applications, such as magnets, lasers, and glass coloration. It is not directly related to medical terminology or healthcare.

I'm not able to provide a specific medical definition for the term "Decalcification Technique" as it is not a standard term in medical or scientific literature. However, decalcification is a process that is commonly used in histology (the study of the microscopic structure of tissues) to prepare calcium-containing tissue samples for sectioning and staining.

Decalcification involves removing the calcium salts from the tissue using a weak acid solution, such as formic acid or acetic acid. This process makes it possible to cut thin sections of the tissue with a microtome (a tool used to cut thin slices of tissue for examination under a microscope).

The decalcification technique may refer to the specific method or protocol used to decalcify tissue samples, including the type and concentration of acid used, the duration of decalcification, and the temperature at which the process is carried out. The choice of decalcification technique will depend on the type and size of the tissue sample being prepared, as well as the specific research or diagnostic questions being addressed.

Hydrofluoric acid is not typically considered a medical term, but rather a chemical one. However, it's important for medical professionals to be aware of its potential hazards and health effects.

Hydrofluoric acid (HF) is a highly corrosive and toxic liquid, which is colorless or slightly yellowish. It is a solution of hydrogen fluoride in water. It is used in various industries for etching glass, cleaning metal surfaces, manufacturing semiconductors, and in chemical research.

In terms of health effects, exposure to HF can cause severe burns and tissue damage. Even at very low concentrations, it can cause pain and irritation to the skin and eyes. Inhalation can lead to respiratory irritation, coughing, and choking. If ingested, it can be fatal due to its ability to cause deep burns in the gastrointestinal tract and potentially lead to systemic fluoride toxicity. Delayed medical attention can result in serious complications, including damage to bones and nerves.

I believe there might be a slight confusion in your question. Sulfuric acid is not a medical term, but instead a chemical compound with the formula H2SO4. It's one of the most important industrial chemicals, being a strong mineral acid with numerous applications.

If you are asking for a definition related to human health or medicine, I can tell you that sulfuric acid has no physiological role in humans. Exposure to sulfuric acid can cause irritation and burns to the skin, eyes, and respiratory tract. Prolonged exposure may lead to more severe health issues. However, it is not a term typically used in medical diagnoses or treatments.

Trace elements are essential minerals that the body needs in very small or tiny amounts, usually less than 100 milligrams per day, for various biological processes. These include elements like iron, zinc, copper, manganese, fluoride, selenium, and iodine. They are vital for maintaining good health and proper functioning of the human body, but they are required in such minute quantities that even a slight excess or deficiency can lead to significant health issues.

Hydrochloric acid, also known as muriatic acid, is not a substance that is typically found within the human body. It is a strong mineral acid with the chemical formula HCl. In a medical context, it might be mentioned in relation to gastric acid, which helps digest food in the stomach. Gastric acid is composed of hydrochloric acid, potassium chloride and sodium chloride dissolved in water. The pH of hydrochloric acid is very low (1-2) due to its high concentration of H+ ions, making it a strong acid. However, it's important to note that the term 'hydrochloric acid' does not directly refer to a component of human bodily fluids or tissues.

Nitrates are chemical compounds that consist of a nitrogen atom bonded to three oxygen atoms (NO3-). In the context of medical science, nitrates are often discussed in relation to their use as medications or their presence in food and water.

As medications, nitrates are commonly used to treat angina (chest pain) caused by coronary artery disease. Nitrates work by relaxing and widening blood vessels, which improves blood flow and reduces the workload on the heart. Some examples of nitrate medications include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.

In food and water, nitrates are naturally occurring compounds that can be found in a variety of vegetables, such as spinach, beets, and lettuce. They can also be present in fertilizers and industrial waste, which can contaminate groundwater and surface water sources. While nitrates themselves are not harmful, they can be converted into potentially harmful compounds called nitrites under certain conditions, particularly in the digestive system of young children or in the presence of bacteria such as those found in unpasteurized foods. Excessive levels of nitrites can react with hemoglobin in the blood to form methemoglobin, which cannot transport oxygen effectively and can lead to a condition called methemoglobinemia.

I'm sorry for any confusion, but "microwaves" is not a term typically used in medical definitions. Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; they are commonly used in communication devices and home appliances such as microwave ovens. If you have any questions related to health or medicine, please provide more context so I can give you a more accurate response.

In the context of medicine and medical devices, calibration refers to the process of checking, adjusting, or confirming the accuracy of a measurement instrument or system. This is typically done by comparing the measurements taken by the device being calibrated to those taken by a reference standard of known accuracy. The goal of calibration is to ensure that the medical device is providing accurate and reliable measurements, which is critical for making proper diagnoses and delivering effective treatment. Regular calibration is an important part of quality assurance and helps to maintain the overall performance and safety of medical devices.

Environmental monitoring is the systematic and ongoing surveillance, measurement, and assessment of environmental parameters, pollutants, or other stressors in order to evaluate potential impacts on human health, ecological systems, or compliance with regulatory standards. This process typically involves collecting and analyzing data from various sources, such as air, water, soil, and biota, and using this information to inform decisions related to public health, environmental protection, and resource management.

In medical terms, environmental monitoring may refer specifically to the assessment of environmental factors that can impact human health, such as air quality, water contamination, or exposure to hazardous substances. This type of monitoring is often conducted in occupational settings, where workers may be exposed to potential health hazards, as well as in community-based settings, where environmental factors may contribute to public health issues. The goal of environmental monitoring in a medical context is to identify and mitigate potential health risks associated with environmental exposures, and to promote healthy and safe environments for individuals and communities.

Copper is a chemical element with the symbol Cu (from Latin: *cuprum*) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. Copper is found as a free element in nature, and it is also a constituent of many minerals such as chalcopyrite and bornite.

In the human body, copper is an essential trace element that plays a role in various physiological processes, including iron metabolism, energy production, antioxidant defense, and connective tissue synthesis. Copper is found in a variety of foods, such as shellfish, nuts, seeds, whole grains, and organ meats. The recommended daily intake of copper for adults is 900 micrograms (mcg) per day.

Copper deficiency can lead to anemia, neutropenia, impaired immune function, and abnormal bone development. Copper toxicity, on the other hand, can cause nausea, vomiting, abdominal pain, diarrhea, and in severe cases, liver damage and neurological symptoms. Therefore, it is important to maintain a balanced copper intake through diet and supplements if necessary.

Medical definitions of water generally describe it as a colorless, odorless, tasteless liquid that is essential for all forms of life. It is a universal solvent, making it an excellent medium for transporting nutrients and waste products within the body. Water constitutes about 50-70% of an individual's body weight, depending on factors such as age, sex, and muscle mass.

In medical terms, water has several important functions in the human body:

1. Regulation of body temperature through perspiration and respiration.
2. Acting as a lubricant for joints and tissues.
3. Facilitating digestion by helping to break down food particles.
4. Transporting nutrients, oxygen, and waste products throughout the body.
5. Helping to maintain healthy skin and mucous membranes.
6. Assisting in the regulation of various bodily functions, such as blood pressure and heart rate.

Dehydration can occur when an individual does not consume enough water or loses too much fluid due to illness, exercise, or other factors. This can lead to a variety of symptoms, including dry mouth, fatigue, dizziness, and confusion. Severe dehydration can be life-threatening if left untreated.

Copper sulfate is an inorganic compound with the chemical formula CuSO₄. It is a common salt of copper and is often found as a blue crystalline powder. Copper sulfate is used in various applications, including as a fungicide, algicide, and in some industrial processes.

In medical terms, copper sulfate has been historically used as an emetic (a substance that causes vomiting) to treat poisoning. However, its use for this purpose is not common in modern medicine due to the availability of safer and more effective emetics. Copper sulfate can be harmful or fatal if swallowed, and it can cause burns and irritation to the skin and eyes. Therefore, it should be handled with care and kept out of reach of children and pets.
