Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes.

This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.Obesity: A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).Mutation: Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.Computer Simulation: Computer-based representation of physical systems and phenomena such as chemical processes.Pregnancy: The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.Prevalence: The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time.Body Mass Index: An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese).

The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air. It moves downward when we breathe in, enlarging the chest cavity and pulling air in through the nose or mouth. When we breathe out, the diaphragm moves upward, forcing the chest cavity to get smaller and pushing the gases in the lungs up and out of the nose and mouth. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also enabling the body to get rid of carbon dioxide in the air breathed out. Air pressure in the chest c...

What Is the Connection between the Respiratory System and Homeostasis. What Is the Connection between the Respiratory System and Homeostasis. The lungs and trachea help rid the body of carbon dioxide. The respiratory system controls breathing processes in the body. Parts of the respiratory system can help stabilize pH levels in the blood and regulate the body's temperature. In addition, the gas exchange processes and actual breathing mechanisms facilitated by the respiratory system may be considered a form of homeostasis. Some of the factors that homeostasis is responsible for within a human being include body temperature, blood sugar levels, and acidity levels. Negative feedback helps facilitate breathing, so it fuels the processes of homeostasis and the respiratory system. The whole gas exchange process between carbon dioxide and oxygen that sustains the respiratory system is an example of homeostasis. The lungs, trachea, and other components help the body get rid of wasteful carbon dioxide. At the same tim...

Lung volumes were determined by helium dilution. An exponential curve of the form V = Vmax - Ae-KP was fitted to the pressure-volume data from each sheep where P is the static recoil pressure, Vmax represents the volume asymptote, A is the difference between Vmax and the intercept on the volume axis and K defines the slope and hence the shape of the P-V curve. Quality of fit of the data was assessed visually, by means of a sign test and a runs test and by the coefficient of determination r2. Exponential equations were found to adequately describe the shape of the pressure-volume curve in sheep. The exponent K was not correlated with effe...

*  Cheyne–Stokes respiration
... Name = Cheyne–Stokes respiration. 2 Cheyne–Stokes respiration and periodic breathing are the two regions on a spectrum of severity of oscillatory tidal volume. In heart failure, the mechanism of the oscillation is unstable feedback in the respiratory control system. In normal respiratory control, negative feedback allows a steady level of alveolar gas concentrations to be maintained, and therefore stable tissue levels of oxygen and carbon dioxide CO 2. At the steady state, the rate of production of CO 2 equals the net rate at which it is exhaled from the body, which assuming no CO 2 in the ambient air is the product of the alveolar ventilation and the end-tidal CO 2 concentration. Alveolar ventilation = body CO 2 production/end-tidal CO 2 fraction. Through respiratory control reflexes, any small transient fall in ventilation A leads to a corresponding small rise A' in alveolar CO 2 concentration which is sensed by the respiratory control system so that there is a subsequent small compensatory rise in ven...

... 'Upper airway resistance syndrome' or 'UARS' is a sleep disorder characterized by airway resistance to breath ing during sleep. Diagnosis Explanation Pathophysiology Clinical presentation Treatment Behavioral modification. Positive airway pressure therapy. Prognosis See also References External links. From obstructive sleep apnea syndrome to upper airway resistance syndrome: consistency of daytime sleepiness. Pathophysiology of UARS is similar to obstructive sleep apnea / hypopnea syndrome in that abnormal airway resistance in the upper airway during sleep leads to unwanted physiologic consequences. Increased upper airway resistance in this disorder does not lead to cessation of airflow apnea or decrease in airflow hypopnea, but instead leads to an arousal secondary to increased work of breathing to overcome the resistance. Repeated and multiple arousals of which the person is usually unaware result in an abnormal sleep architecture and daytime somnolence sleepiness. Arousals result in sympathetic activa...

DC Metering Circuits Kelvin 4-wire Resistance Measurement. Kelvin 4-wire Resistance Measurement. Because we’re only measuring voltage dropped across the subject resistance and not the wires’ resistances, though, the calculated resistance is indicative of the subject component’s resistance R subject alone. Any voltage dropped across the main current-carrying wires will not be measured by the voltmeter, and so do not factor into the resistance calculation at all. Resistance this low is comparable to wire connection resistance, which means voltage measured across such a shunt must be done so in such a way as to avoid detecting voltage dropped across the current-carrying wire connections, lest huge measurement errors be induced. This way, the voltmeter only measures voltage dropped across the precision resistance itself, without any stray voltages dropped across current-carrying wires or wire-to-terminal connection resistances. There will still be compound error between the standard resistor and the voltmeter use...

Arc Fault Circuit Interrupters The AFCI breaker performs a different job entirely from GFIs, Ground Fault Interrupter GFCI breakers and outlets. About half of all residential electrical fires involve electrical wiring. Arc fault circuit interrupters AFCIs involve a technology that detects arcing-faults in electrical circuits that could cause fires. By recognizing characteristics unique to arcing and functioning to de-energize the circuit when an arc-fault is detected, AFCIs further reduce the risk of fire beyond the scope of conventional fuses and circuit breakers. Conventional circuit breakers only respond to overloads and short circuits; so they do not protect against arcing conditions that produce erratic, and often reduced current. The AFCI circuitry continuously monitors the current and discriminates between normal and unwanted arcing conditions. An AFCI should not trip during normal arcing conditions, which can occur when a switch is opened or...

Using boli of a second insoluble gas delivered at a given point during inspirations of a multibreath washout test, the proportions of labeled inspired ventilation reaching the poorly and well-ventilated regions may be determined by analyzing the kinetics of the exhaled tracer. We studied eight normal subjects breathing through large-bore solenoid valves controlled to maintain tidal volume at 600 or 900 ml. Boli consisting of 15 ml of 80% He-20% O2 were delivered over 75 ms; this labeled approximately 125 ml of inspired gas. Boli were delivered after 50 ml had been inspired to mark early inspiration and after 300 ml had been inspired to mark midinspiration. Using 900-ml tidal breaths, late inspira...

*  Functional residual capacity
... thumb|400px|Lung Volumes 'Functional Residual Capacity' 'FRC' is the volume of air present in the lungs at the end of passive expiration. At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles. FRC is the sum of Expiratory Reserve Volume ERV and Residual Volume RV and measures approximately 2400 mL in an 80 kg, average-sized male. It can not be estimated through spirometry, since it includes the residual volume. In order to measure RV precisely, one would need to perform a test such as nitrogen washout, helium dilution or body plethysmography. A lowered or elevated FRC is often an indication of some form of respiratory disease. For instance, in emphysema, FRC is increased, because the lungs are more compliant and the equilibrium between the inward recoil of the lungs and outward recoil of the chest wall is disturbed. As such, patients with emphysema often have noticeably broader chests due to the rel...

Functional residual capacity As PMA increased, a continuous rise p 0.001 in the end-expiratory lung volume measured either by body plethysmography FRC pleth or the SF 6 multiple breath washout technique FRC SF6 was evident in both groups Figure 7. No statistically significant difference in FRC pleth was apparent when former BPD and non-BPD infants were compared, whereas FRC SF6 was significantly lower p = 0.036 in the former BPD infants. In the present study, the most significant lung function differences between the two patient groups were in the tidal breathing parameters V T , V' E , lung compliance and end-expiratory lung volume. However, all differences in tidal breathing, lung compliance and FRC values disappeared after normalization of such parameters to actual body weight. also found that the respiratory compliance of VLBW infants with former BPD became normal at 2 years of age. Only a few studies have measured tidal breathing parameters in preterm BPD infants. The strengths are the depth at which LFT...

Steps History: 1+CK+CS+3 Posts: 752 Threads: 124 Thanked 596 Times in 262 Posts Reputation: 616. Because of the fibrotic nature of restrictive lung diseases, there's a radial traction on the walls of the bronchioles on expiration. This traction pulls on the walls of the bronchioles in a circumferential manner, in a direction opposite to the lumen, so they become dilated, increasing the forced expiratory volume FEV1. This is why FEV1/FVC ratio is above 80% in restrictive lung diseases, although tot...

Lung Protein May Predict Heart Risk Study Shows Protein Levels in Blood May Indicate Risk of Heart Attack and Stroke By Salynn Boyles WebMD Health News Reviewed by Laura J. June 10, 2011 -- A promising blood test for lung injury may also predict heart attack and stroke risk as well as death from cardiovascular causes. In a large study from Canada, high levels of circulating surfactant protein-D SP-D in the blood were found to be strongly predictive of death from heart and vascular causes, independent of established risk factors for heart attack and stroke. SP-D levels rise in response to lung inflammation, and the finding suggests that elevated levels in the blood in response to lung damage from smoking, air pollution, and other causes may have a direct role in cardiovascular disease, lung specia...

Lung infiltrate 01/25/2008. Question: What is it. What specifically causes it. Can it automatically be assumed that it is TB. If not, what other possibilities exist. Answer: Your lungs are usually filled with air as you breathe in and out. When you get a chest x-ray, the air in the lungs causes the x-ray to appear black. Sometimes a shadow white can appear on the lung. This can be from an infiltrate or a collapse of the lung. If you have an old chest x-ray, doctors can see if the change is new or old to compare. A collapse of the lung or atelectasis means that area of the lung is not receiving air so the lungs are not expanding. An infiltrate occ...

Abstract Background Activation of the innate immune system plays a key role in exacerbations of chronic lung disease. We hypothesized that alarmins released from lung epithelium during environmental insults such as oxidant injury and viral infection might induce innate immune responses in lung fibroblasts. Methods Human bronchial epithelial cells BECs and human lung fibroblasts HLFs were cultured from brushings taken from lung transplant recipients and resected lung tissue respectively. Wild-type and Il1a-/- mice were infected with Inf...

The lung or pulmonary system is the essential respiration organ in air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located in the chest on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere. In order to completely explain the anatomy of the lungs, it is necessary to discuss the passage of air through the mouth to the alveoli. Once air progresses through the mouth or nose, it travels through the oropharynx, nasopharynx, the larynx, the trach...

Clean Your Lungs - Out. After Smoking. Smoking Causes. Clean your lungs...quick, easy and handy tips. Tips to clean your lungs are available for people who have been smoking and have quit. These tips are also applicable to people who are currently smoking and may help reduce the risk of resultant effects of smoke in your lungs. Cleaning your lungs is essentially a natural process which is also known as lung detox. When you clean your lungs you will be getting rid of toxins that would have accumulated in your lungs over time. To better understand why lung detox is absolutely necessary lets consider the effects of smoking in brief. Carbon monoxide together with other toxins are absorbed into the bloodstream and also head-out to do their destructive work in your system. Because your lungs are endowed with natural methods of self cleaning.

... September 4, 2013 Clinical tool accurately classifies benign and malignant spots on lung scans of smokers September 4, 2013 A Terry Fox Research Institute TFRI -led study has developed a new clinical risk calculator software that accurately classifies, nine out of ten times, which spots or lesions nodules are benign and malignant on an initial lung computed tomography CT scan among individuals at high risk for lung cancer. "An accurate and practical model that can predict the probability that a lung nodule is malignant and that can be used to guide clinical decision making will reduce costs and the risk of morbidity and mortality in screening programs," wrote Dr. Lam and study colleagues in the article, titled: Probability of Cancer in Pulmonary Nodules Detected on First Screening Computed Tomography." "The findings in this study bolster the potential for the successful implementation of a lung cancer screening program using low-dose computed tomography CT within a high-risk population.

Richard Knox. The task force estimates that its proposed recommendation will cut U.S. "And 20,000 lives is a lot of people." He says the lung cancer screening test – a computed tomography or CT scan – is actually more effective than mammography or colonoscopy in saving lives. Murphy, who smoked for three decades, started getting yearly lung scans in 2005 as part of a study. "Oh absolutely, that scan saved my life," Murphy tells Shots. And I believe to this day that it saved my life." The proposed recommendation is aimed at people who are at especially high risk of lung cancer. Nearly 90 million Americans are smokers or former smokers. "We are actually going to do some lung surgery on people just to prove that they don't have cancer," LeFevre says. A federal task force is planning to urge millions of smokers and former smokers to get an annual test that looks for early signs of lung cancer. But as we hear from NPR's Richard Knox, the screening has some important downsides. Preventive Services Task Force says i...

This aid to learning also includes an introduction to wider harmful consequences as exemplified by the effects on cellular respiration. It will exclude infection and consequences of radioactivity. It complements other modes of learning in the module. Relevant Fundamentals of Lung Structure and Function The airways of the lung derive from the trachea wind pipe downwards by progressive division into two or more branches. Those airways beyond the trachea that contain cartilage are called bronchi. The airways lacking in cartilage beyond the bronchi are the bronchioles. These lead into hollow spaces called alveoli which have a diameter of about 0.1 mm each. There are approximately 300 million alveoli and their total surface area is about 140 m 2. The conducting airways are lined by cells with cilia small motile surface projections. Inter...

Symptoms of quitting smoking 8 replies : I just quit smoking 1 or 2 pks per week. Sep 02, 2005. My daughter started smoking at around the same age as you - 13. Once you get cancer, say lung cancer, it is unlikely that you beat the disease. It is soo easy for someone who has never smoked or who has smoked and quit to give holier than thou advice. Continue to make attempts to quit even if it is for only a few days at a time, as they say every time you quit, even if you start again, it becomes easier to quit in the long run for good. His father died of small cell carcinoma twenty years out from quitting; his paternal aunt had a lung removed she's still alive, luckily, his other paternal aunt died of lung cancer, and her daughter his cousin died of throat cancer. No, I'll admit I don't know what it's like to try to quit, but I've heard...

Cheyne–Stokes respirationLung receptor: Lung receptors sense irritation or inflammation in the bronchi and alveoli.Plateau pressure: Plateau pressure (PPLAT) is the pressure applied to small airways and alveoli during positive-pressure mechanical ventilation.Morgan, Edward G.DimefoxSwim bladder: The swim bladder, gas bladder, fish maw or air bladder is an internal gas-filled organ that contributes to the ability of a fish to control its buoyancy, and thus to stay at its current water depth without having to waste energy in swimming. Also, the dorsal position of the swim bladder means the center of mass is below the center of volume, allowing it to act as a stabilizing agent.Peak inspiratory pressure: Peak inspiratory pressure (PIP) is the highest level of pressure applied to the lungs during inhalation. In mechanical ventilation the number reflects a positive pressure in centimeters of water pressure (cmH2O).BalloonMayer waves: Mayer waves are cyclic changes or waves in arterial blood pressure brought about by oscillations in baroreceptor and chemoreceptor reflex control systems. The waves are seen both in the ECG and in continuous blood pressure curves and have a frequency about 0.Nasal EPAPSpirometer: A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs.Infant respiratory distress syndromeTrachealis muscle: The trachealis muscle is a smooth muscle that bridges the gap between the free ends of C-shaped cartilages at the posterior border of the trachea, adjacent to the esophagus.Medical ventilator: A medical ventilator (or simply ventilator in context) is a machine designed to mechanically move breathable air into and out of the lungs, to provide the mechanism of breathing for a patient who is physically unable to breathe, or breathing insufficiently.Flat-chested kitten syndrome: Flat-chested kitten syndrome (FCKS), is a disorder in cats, wherein kittens develop a compression of the thorax (chest/ribcage) caused by vertebral malformation. In mild cases, the underside of the chest becomes flattened (hence the name of the condition); in extreme cases the entire thorax is flattened, looking as if the kitten has been stepped on.Optoelectronic plethysmography: Optoelectronic plethysmography (OEP) is a method to evaluate ventilation through an external measurement of the chest wall surface motion.Arteriovenous oxygen difference: The arteriovenous oxygen difference, or a-vO2 diff, is the difference in the oxygen content of the blood between the arterial blood and the venous blood. It is an indication of how much oxygen is removed from the blood in capillaries as the blood circulates in the body.Respirometer: A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. They allow investigation into how factors such as age, chemicals or the effect of light affect the rate of respiration.Chronic lung diseasePlethysmographMethacholineMiddlesex County Hospital: Middlesex County Hospital was a hospital operated by Middlesex County which was operational from the 1930s until 2001 in Waltham and Lexington, Massachusetts. Originally opened as a tuberculosis hospital, the hospital eventually became the county hospital for Middlesex until its closure in 2001.BradypneaTranspulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.Hadrosaur diet: Hadrosaurids, also commonly referred to as duck-billed dinosaurs or hadrosaurs, were large terrestrial herbivores. The diet of hadrosaurid dinosaurs remains a subject of debate among paleontologists, especially regarding whether hadrosaurids were grazers who fed on vegetation close to the ground, or browsers who ate higher-growing leaves and twigs.Moens–Korteweg equation: In biomechanics, the Moens–Korteweg equation models the relationship between wave speed or pulse wave velocity (PWV) and the incremental elastic modulus of the arterial wall or its distensibility. The equation was derived independently by Adriaan Isebree Moens and Diederik Korteweg.List of countries by carbon dioxide emissionsBronchoconstriction: Bronchoconstriction is the constriction of the airways in the lungs due to the tightening of surrounding smooth muscle, with consequent coughing, wheezing, and shortness of breath.Swiss Institute of Allergy and Asthma Research: Swiss Institute of Allergy and Asthma Research (SIAF), founded in 1988, performs basic research in the field of allergy and asthma with the aim to improve the understanding and treatment of these conditions, which affect around 30-40% of the westernized population. The Institute has its roots in the Tuberculosis Research Institute of Davos, a medical society founded in 1905 to study the beneficial effects of high altitude treatment of tuberculosis.AlligatorAerosolization: Aerosolization is the process or act of converting some physical substance into the form of particles small and light enough to be carried on the air i.e.History of tracheal intubation: Tracheal intubation (usually simply referred to as intubation), an invasive medical procedure, is the placement of a flexible plastic catheter into the trachea. For millennia, tracheotomy was considered the most reliable (and most risky) method of tracheal intubation.Matrix model: == Mathematics and physics ==Luis Gabriel Cano: Luis Gabriel Cano Isaza (1924-2010)El Espectador obituary (In Spanish) was the President and publisher of El Espectador who won the Golden Pen of Freedom Award in 1990 for his writings on the cocaine traffic. His brother Guillermo, who had also worked on the paper, had been assassinated by drug gangs.EprozinolPotassium cyanideObesity hypoventilation syndromeDead space (physiology): In physiology, dead space is the volume of air which is inhaled that does not take part in the gas exchange, either because it (1) remains in the conducting airways, or (2) reaches alveoli that are not perfused or poorly perfused. In other words, not all the air in each breath is available for the exchange of oxygen and carbon dioxide.Helium-3Diaphragmatic excursion: Diaphragmatic excursion is the movement of the thoracic diaphragm during breathing.Diaphragm pacing: == Introduction ==Air sensitivity: Air sensitivity is a term used, particularly in chemistry, to denote the reactivity of chemical compounds with some constituent of air. Most often, reactions occur with atmospheric oxygen (O2) or water vapor (H2O),Handling and Storage of Air-Sensitive Reagents, Technical Bulletin AL-134, Sigma-Aldrich although reactions with the other constituents of air such as carbon monoxide (CO), carbon dioxide (CO2), and nitrogen (N2) are also possible.Alexander Walker (physiologist): Alexander Walker (1779—1852) was a Scottish physiologist, aesthetician, encyclopaedist, translator, novelist, and journalist.Isocyanide: An isocyanide (also called isonitrile or carbylamine) is an organic compound with the functional group -N≡C. It is the isomer of the related cyanide (-C≡N), hence the prefix iso.Ventolin (EP): "Ventolin" is a piece of electronic music composed by Cornish musician Richard D James. It is noted for its harsh, abrasive sound.Alveolar gas equation: The partial pressure of oxygen (pO2) in the pulmonary alveoli is required to calculate both the alveolar-arterial gradient of oxygen and the amount of right-to-left cardiac shunt, which are both clinically useful quantities. However it is not practical to take a sample of gas from the alveoli in order to directly measure the partial pressure of oxygen.Air displacement pipetteGas analysis: Gas analysis could refer to any of the following:Timeline of chemical warfareP-AnisidineLying (position)Bronchodilator: A bronchodilator is a substance that dilates the bronchi and bronchioles, decreasing resistance in the respiratory airway and increasing airflow to the lungs. Bronchodilators may be endogenous (originating naturally within the body), or they may be medications administered for the treatment of breathing difficulties.Lower respiratory tract infection: Lower respiratory tract infection (LRTI), while often used as a synonym for pneumonia, can also be applied to other types of infection including lung abscess and acute bronchitis. Symptoms include shortness of breath, weakness, fever, coughing and fatigue.Hyperventilation syndromeCostovertebral angleAcute esophageal necrosis

(1/2373) Physical characterization of a low-charge glycoform of the MUC5B mucin comprising the gel-phase of an asthmatic respiratory mucous plug.

We have previously noted that sequential extraction of an asthmatic mucous exudate with 6 M guanidinium chloride yielded a fraction of the mucins that were most resistant to solubilization and of high Mr [Sheehan, Richardson, Fung, Howard and Thornton (1995) Am. J. Respir. Cell Mol. Biol. 13, 748-756]. Here we show that this mucin fraction is dominated (at least 96% of the total) by the low-charge glycoform of the MUC5B gene product. Seen in the electron microscope the mucins appeared mainly as compact 'island' structures composed of linear threads often emanating from globular 'nodes' rather than the discrete linear threads more typical of mucins that we have previously described. The effect of reducing agents was as expected for other gel-forming mucins, i.e. reduced subunits or monomers of Mr 3x10(6)) were produced within 15 min of treatment. Kinetic experiments on the cleavage of the intact mucins with the proteinase trypsin indicated two clear regimes of fragmentation. An initial rapid cleavage generated mucins ranging from Mr=4x10(6) to 30x10(6) that in the electron microscope appeared as polydisperse threads (500-3000 nm in length), similar to normal and other respiratory mucins that we have previously characterized. A subsequent slower fragmentation over many hours yielded a major fragment of Mr 3x10(6) and length 200-600 nm, very similar in size and Mr to the subunits obtained by reduction. The results suggest that the MUC5B mucin is assembled, first into polydisperse linear threads, which are then linked together via a protein-mediated process. This might involve part of the mucin polypeptide or an as yet unidentified protein(s). The high proteinase susceptibility of the linkage suggests that it might be a point of control for mucin size and thus mucus rheology.  (+info)

(2/2373) Capsaicin-sensitive C-fiber-mediated protective responses in ozone inhalation in rats.

To assess the role of lung sensory C fibers during and after inhalation of 1 part/million ozone for 8 h, we compared breathing pattern responses and epithelial injury-inflammation-repair in rats depleted of C fibers by systemic administration of capsaicin as neonates and in vehicle-treated control animals. Capsaicin-treated rats did not develop ozone-induced rapid, shallow breathing. Capsaicin-treated rats showed more severe necrosis in the nasal cavity and greater inflammation throughout the respiratory tract than did control rats exposed to ozone. Incorporation of 5-bromo-2'-deoxyuridine (a marker of DNA synthesis associated with proliferation) into terminal bronchiolar epithelial cells was not significantly affected by capsaicin treatment in rats exposed to ozone. However, when normalized to the degree of epithelial necrosis present in each rat studied, there was less 5-bromo-2'-deoxyuridine labeling in the terminal bronchioles of capsaicin-treated rats. These observations suggest that the ozone-induced release of neuropeptides does not measurably contribute to airway inflammation but may play a role in modulating basal and reparative airway epithelial cell proliferation.  (+info)

(3/2373) Mediators of anaphylaxis but not activated neutrophils augment cholinergic responses of equine small airways.

Neutrophilic inflammation in small airways (SA) and bronchospasm mediated via muscarinic receptors are features of chronic obstructive pulmonary disease in horses (COPD). Histamine, serotonin, and leukotrienes (LTs) are reported to be involved in the exacerbation of COPD, and currently, histamine has been shown to increase tension response to electrical field simulation (EFS) in equine SA. We tested the effects of these mediators and the effects of activated neutrophils on the cholinergic responses in SA. Histamine, serotonin, and LTD4 had a synergistic effect on EFS responses and only an additive effect on the tension response to exogenous ACh or methacholine. Atropine and TTX entirely eliminated the EFS-induced tension response in the presence of all three inflammatory mediators, indicating that augmentation of the EFS response applies only to the endogenous cholinergic response. Neutrophils isolated from control and COPD-affected horses were activated by zymosan, producing 18.1 +/- 2.3 and 25.0 +/- 2.3 nmol superoxide. 10(6) cells-1. 30 min-1, respectively. However, in contrast to the profound effect of mediators, incubation of SA for over 1 h in a suspension of up to 30 x 10(6) zymosan-treated neutrophils/ml did not significantly affect EFS responses of SA isolated from either control or COPD-affected horses. We conclude that in equine SA 1) the endogenous cholinergic responses are subject to strong facilitation by inflammatory mediators; 2) activated neutrophils do not affect cholinergic responses in SA; and 3) in acute bouts of equine COPD, histamine, LTD4, and serotonin (mediators primarily associated with type I allergic reaction) rather than mediators derived from neutrophils most likely contribute to increased cholinergic airway tone.  (+info)

(4/2373) Conserved function of mSpry-2, a murine homolog of Drosophila sprouty, which negatively modulates respiratory organogenesis.

In Drosophila embryos, the loss of sprouty gene function enhances branching of the respiratory system. Three human sprouty homologues (h-Spry1-3) have been cloned recently, but their function is as yet unknown [1]. Here, we show that a murine sprouty gene (mSpry-2), the product of which shares 97% homology with the respective human protein, is expressed in the embryonic murine lung. We used an antisense oligonucleotide strategy to reduce expression of mSpry-2 by 96%, as measured by competitive reverse transcriptase PCR, in E11. 5 murine embryonic lungs cultured for 4 days [2]. Morphologically, the decrease in mSpry-2 expression resulted in a 72% increase in embryonic murine lung branching morphogenesis as well as a significant increase in expression of the lung epithelial marker genes SP-C, SP-B and SP-A. These results support a striking conservation of function between the Drosophila and mammalian sprouty gene families to negatively modulate respiratory organogenesis.  (+info)

(5/2373) Epidermal growth factor system regulates mucin production in airways.

Goblet-cell hyperplasia is a critical pathological feature in hypersecretory diseases of airways. However, the underlying mechanisms are unknown, and no effective therapy exists. Here we show that stimulation of epidermal growth factor receptors (EGF-R) by its ligands, EGF and transforming growth factor alpha (TGFalpha), causes MUC5AC expression in airway epithelial cells both in in vitro and in vivo. We found that a MUC5AC-inducing epithelial cell line, NCI-H292, expresses EGF-R constitutively; EGF-R gene expression was stimulated further by tumor necrosis factor alpha (TNFalpha). EGF-R ligands increased the expression of MUC5AC at both gene and protein levels, and this effect was potentiated by TNFalpha. Selective EGF-R tyrosine kinase inhibitors blocked MUC5AC expression induced by EGF-R ligands. Pathogen-free rats expressed little EGF-R protein in airway epithelial cells; intratracheal instillation of TNFalpha induced EGF-R in airway epithelial cells, and subsequent instillation of EGF-R ligands increased the number of goblet cells, Alcian blue-periodic acid-Schiff staining (reflecting mucous glycoconjugates), and MUC5AC gene expression, whereas TNFalpha, EGF, or TGFalpha alone was without effect. In sensitized rats, three intratracheal instillations of ovalbumin resulted in EGF-R expression and goblet-cell production in airway epithelium. Pretreatment with EGF-R tyrosine kinase inhibitor, BIBX1522, prevented goblet-cell production both in rats stimulated by TNFalpha-EGF-R ligands and in an asthma model. These findings suggest potential roles for inhibitors of the EGF-R cascade in hypersecretory diseases of airways.  (+info)

(6/2373) Pulmonary expression of interleukin-13 causes inflammation, mucus hypersecretion, subepithelial fibrosis, physiologic abnormalities, and eotaxin production.

Interleukin (IL)-13 is a pleiotropic cytokine produced in large quantities by activated CD4(+) Th2 lymphocytes. To define further its potential in vivo effector functions, the Clara cell 10-kDa protein promoter was used to express IL-13 selectively in the lung, and the phenotype of the resulting transgenic mice was characterized. In contrast to transgene-negative littermates, the lungs of transgene-positive mice contained an inflammatory response around small and large airways and in the surrounding parenchyma. It was mononuclear in nature and contained significant numbers of eosinophils and enlarged and occasionally multinucleated macrophages. Airway epithelial cell hypertrophy, mucus cell metaplasia, the hyperproduction of neutral and acidic mucus, the deposition of Charcot-Leyden-like crystals, and subepithelial airway fibrosis were also prominently noted. Eotaxin protein and mRNA were also present in large quantities in the lungs of the transgene-positive, but not the transgene-negative, mice. IL-4, IL-5, granulocyte-macrophage colony-stimulating factor, and monocyte chemoattractant protein-5 were not similarly detected. Physiological evaluations revealed significant increases in baseline airways resistance and airways hyperresponsiveness (AHR) to methacholine in transgene-positive animals. Thus, the targeted pulmonary expression of IL-13 causes a mononuclear and eosinophilic inflammatory response, mucus cell metaplasia, the deposition of Charcot-Leyden-like crystals, airway fibrosis, eotaxin production, airways obstruction, and nonspecific AHR. IL-13 may play an important role in the pathogenesis of similar responses in asthma or other Th2-polarized tissue responses.  (+info)

(7/2373) Behaviour and aeration of the respiratory system in the domestic fowl embryo.

1. The monitoring of developmental stage and under-water dissection were used to examine the initial aeration of the respiratory system in domestic fowl embryos. 2. A virtually complete absence of free air within the chorioallantois was found before the beak had begun to make 'beak-clapping' movements, even when the membranes were already draped over its tip. 3. During the 'beak-clapping' stage, but before the membranes were pierced and before respiratory movements had begun, many embryos were found to contain free bubbles of air within the trachea and air sacs. 4. All embryos in which the respiratory system was aerated were found also to have froth in the crop or other parts of the digestive system. 5. Air was found in both the respiratory and digestive systems of all embryos examined after membrane penetration by the beak. 6. When air was injected into the chorioallantois before the stage of initial aeration it was recovered 5 min later from both the respiratory and digestive systems in under-water dissections. 7. It is suggested that lung ventilation takes place in the avian embryo in three distinct stages: the major air-ways become aerated, then respiratory movements begin and lastly the tertiary bronchi are slowly aerated. It is suggested also that movements involved in the imbibing of fluids play a part in aeration before the membranes are pierced.  (+info)

(8/2373) Suppression of airway inflammation by theophylline in adult bronchial asthma.

BACKGROUND: Chronic continuous airway inflammation caused by eosinophils has been noted to play critical roles in the pathophysiology of bronchial asthma, in addition to reversible obstruction and hypersensitivity of the respiratory tract. Therefore, suppression of chronic airway inflammation has become more important in asthma treatment. Although theophylline has been a conventionally used bronchodilator, it has been recently reported to have concurrent anti-inflammatory effects. OBJECTIVE: Accordingly, we studied the effects of a slow-release theophylline preparation, Theolong, on airway inflammation. METHODS: Administration of Theolong 400 mg/day to 24 patients with mild or moderate asthma and measuring eosinophil cationic protein (ECP), a marker of airway inflammation, and eosinophils in sputum and peripheral blood at 4 and 8 weeks. RESULTS: As a result, sputum ECP, serum ECP and sputum eosinophil count (%) were significantly lowered after 4 and 8 weeks. CONCLUSION: Thus, in the theophylline-administered group, slow-release theophylline, Theolong, was effective in treating asthma, with anti-inflammatory effects on inflammatory cells besides its bronchodilator action.  (+info)


respiratory system?????


At school, my teacher paired us all up for a science project. We all have to reaserch a different body system. My groups system is the respiratory system. Now my question is, How does the respitory system work with other systems in the body???? And it has to be 3 examples.
----------

you need to research on the net, the respiratory system is a large organ with many functions.


Respiratory System?


Is your heart included in the respiratory system?
----------

Your heart certainly plays a key role, but it is not part of the respiratory system. the heart is part of the circulatory system.


Respiratory system?


Explain how the air comes into and out of the lungs and where it goes once entering the body! please help, thank you!!!
----------

In order to inhale, your medulla sends a message to your diaphragms to contract which makes them pull downward.  This causes a subatmospheric pressure in your lungs causing air to enter.  Once in your lungs, the oxygen goes all the way into microscopic air sacs called alveoli and cross a barrier called the alveoli capillary membrane entering your bloodstream.  At the same time, carbon dioxide leaves your blood stream and enters your lungs.  In order to exhale, your lungs collapse much like a rubber baloon causing the air to leave.  Your lungs normally have a residual amount of air that always remains so that your lungs dont collapse completly.


How does the respiratory system connect to other bodily systems?


I'm doing a science project, and talking about how Pulmonologoy and the respiratory system relates to other bodily system.  I've already found info on the Digestive and and Cardiology system, but I'm at a loss for how it relates to the Endocrine, Excretory and Nervous systems.  If you know any or all, please answer! Thanks so much!
----------

nervous system: there are nerves that enervate the diaphragm (and thoracic muscles), which are critical to muscular manipulation of the lung volume.  

Endocrine: see renin-angiotensin system.

Excretory: perhaps the surfactant excretions that decrease surface energies, so that the lung doesn't collapse onto itself.


What everyday system is similar to how your respiratory system works?


I need help thinking of ways the respiratory works. So if someone can think of a system that works like your respiratory system does, that would be great :) 
If you dont understand my question, think of this; muscles work the same way a rubber band does.

How do the circulatory system, respiratory system and digestive system function together and how do they meet?


how do the circulatory system, respiratory system and digestive system function together and how do they meet in the body?

I would really like to know the answer to this question. I have checked myself and have yet to discover a detailed answer.

thank you very much.
----------

Whoa....rather a complex question that requires an extensive answer to be complete and detailed.  Even with my pretty good knowledge of anatomy I can't do it typing from memory.

Let me refer you to my anatomy bible.  It is the classic 1918 Anatomy of the Human Body by Bartleby.  Even haven been written in 1918....it is still accurate.  The human body hasn't changed.

If the information you need isn't here...it doesn't exist.


What happens in your respiratory system when you inhale dust?


Say a big cloud of dust flies in your face while cleaning out a closet… you will probably cough and sneeze. 
In addition to these violent exhalations, what are the parts of the respiratory system that are working to keep dust out of your lungs? And what are they doing?
----------

That's what the upper respiratory system is all about.If you breathe the dust in through your nose, dust particles get trapped in the mucous membrane right away but what gets by is caught up in the nasal passages with the turbinates. In the nasal cavity air swirls around a bit and that increases the amount of dust that gets trapped when it hits the walls. Now you're down to the pharynx where you've got the epiglottis and a number of other structures there that are lined with moist membranes.All of these trap the dust also. What gets by the larynx and into the trachea has a real problem because the mucous membranes there are much more responsive to inhaled foreign bodies. Mucous is produced by the glands that line the airways. This traps whatever remains of the dust. Now there are structures in your airways that look like little hairs but they are anything but. They are called cillia and their responsibility is a wave like motion to move the excess mucous escalator fashion back up towards the trachea. Once enough mucous gets into the trachea it stimulates a cough, if you haven't already and expels the dust out.


Explain the function of the respiratory system and its function?

The human body is composed of a number of organ systems that work together to perform all the necessary functions of the body. Each organ system is comprised of a number of component organs that work together to accomplish certain tasks.

Here are three important human organ systems:  Circulatory, Respiratory, & Endocrine.

Your group will choose one of these three organ systems.

Imagine that you have been asked to provide an explanation about the structure and function of this system to a specific segment of the general public, perhaps a group of senior citizens, pregnant women, or student athletes, who want to learn more about normal functions of the human body as well as health concerns.

You will be providing the seniors with an informative handout. In this handout you will cover the following topics:

Describe the general function of the system and explain how the organ system contributes to physiological homeostasis of the human organism?
Explain how the organ system interacts with other organ systems in the human body.
List the organs in this system and state the function of each organ listed.
Select one representative organ in this system. Describe its structure and explain how the structure relates to the specific function of the organ. When describing the structure, include details about the types of cells in the organ as well as the types of tissues.
Select one specific disease associated with this organ system and explain how it affects the system and human health
