Elective haemodialysis increases exhaled isoprene. (1/562)

BACKGROUND: Uraemic odour is a characteristic feature of patients with end-stage renal disease (ESRD). However, few investigations have been carried out into the composition of exhaled air in ESRD patients undergoing haemodialysis (HD). Increases of exhaled isoprene levels by a factor of up to 2.7 following HD have been reported. METHODS: We attempted to confirm these findings in 50 patients undergoing HD using haemophan (n=23) or polysulphone (n=27) dialysis membranes. Parallel evaluation of ambient air, calorie intake, medication and haemodynamic variables was performed. Samples were analysed using proton transfer reaction-mass spectrometry (PTR-MS). RESULTS: Significant changes in breath isoprene concentration were observed when comparing patients before [39.14+/-14.96 parts per billion (ppbv)] and after (63.54+/-27.59 ppbv) dialysis (P<0.001). The quotient of values before and after dialysis was 1.84 (SD 1.41). No significant differences in isoprene kinetics were found between the use of haemophan and polysulphone membranes. No significant correlations were observed between isoprene quotients and variations in blood pressure during HD, calorie intake, ingestion of lipid-lowering drugs or serum lipid levels. CONCLUSIONS: Isoprene concentration was higher in the exhaled air of patients after HD as compared with values before HD. Large interindividual variability existed in isoprene kinetics. Oxidative stress appears to be an unlikely cause for this rise. An alternative hypothesis is an influence of respiratory variables on isoprene exhalation based upon Henry's law constant. We therefore propose to perform online monitoring of isoprene exhalation by PTR-MS during the HD session to investigate the possible influence of respiratory variables.  (+info)

Upper airway extraluminal tissue pressure fluctuations during breathing in rabbits. (2/562)

Transmural pressure at any level in the upper airway is dependent on the difference between intraluminal airway and extraluminal tissue pressure (ETP). We hypothesized that ETP would be influenced by topography, head and neck position, resistive loading, and stimulated breathing. Twenty-eight male, New Zealand White, anesthetized, spontaneously breathing rabbits breathed via a face mask with attached pneumotachograph to measure airflow and pressure transducer to monitor mask pressure. Tidal volume was measured via integration of the airflow signal. ETP was measured with a pressure transducer-tipped catheter inserted in the tissues of the lateral (ETPlat, n = 28) and anterior (ETPant, n = 21) pharyngeal wall. Head position was controlled at 30, 50, or 70 degrees, and the effect of addition of an external resistor, brief occlusion, or stimulated breathing was examined. Mean ETPlat was approximately 0.7 cmH2O greater than mean ETPant when adjusted for degree of head and neck flexion (P < 0.05). Mean, maximum, and minimum ETP values increased significantly by 0.7-0.8 cmH2O/20 degrees of head and neck flexion when adjusted for site of measurement (P < 0.0001). The main effect of resistive loading and occlusion was an increase in the change in ETPlat (maximum - minimum ETPlat) and change in ETPant at all head and neck positions (P < 0.05). Mean ETPlat and ETPant increased with increasing tidal volume at head and neck position of 30 degrees (all P < 0.05). In conclusion, ETP was nonhomogeneously distributed around the upper airway and increased with both increasing head and neck flexion and increasing tidal volume. Brief airway occlusion increased the size of respiratory-related ETP fluctuations in upper airway ETP.  (+info)

Purinergic signalling in the medullary mechanisms of respiratory control in the rat: respiratory neurones express the P2X2 receptor subunit. (3/562)

ATP is involved in central respiratory control and may mediate changes in the activity of medullary respiratory neurones during hypercapnia, thus playing an important role in central chemoreception. The main objective of this study was to explore further the role of ATP-mediated signalling in respiratory control and central chemoreception by characterising the profile of the P2X receptors expressed by physiologically identified respiratory neurones. In particular we determined whether respiratory neurones in the rostral ventrolateral medulla (VLM) express P2X2 receptor subunits of the ATP-gated ion channel, since ATP currents evoked at recombinant P2X2 receptors are potentiated by lowering extracellular pH. Experiments were performed on anaesthetised (pentobarbitone sodium 60 mg kg-1 I.P., then 10 mg kg-1 I.V. as required), gallamine-triethiodide-treated (10 mg kg-1 I.V., then 2-4 mg kg-1 h-1 I.V.) and artificially ventilated rats. The VLM respiratory neurones were classified according to the timing of their discharge pattern in relation to that of the phrenic nerve and by the exclusion of pump cells from the study population; these were labelled with Neurobiotin using the juxtacellular method, and visualised with fluorescence microscopy. It was found that a substantial proportion of the VLM respiratory neurones express the P2X2 receptor subunit. P2X2 receptor subunit immunoreactivity was detected in approximately 50 % (six out of 12) of expiratory neurones and in approximately 20 % (two out of 11) of neurones with inspiratory-related discharge (pre-inspiratory and inspiratory). In contrast, no Neurobiotin-labelled VLM respiratory neurones (n = 19) were detectably immunoreactive for the P2X1 receptor subunit. Microionophoretic application of ATP (0.2 M, 20-80 nA for 40 s) increased the activity of approximately 80 % (13 out of 16) of expiratory neurones and of approximately 30 % (five out of 18) of VLM neurones with inspiratory-related discharge. These effects were abolished by the P2 receptor blocker suramin (0.02 M, 80 nA), which also reduced the baseline firing in some expiratory neurones. These data indicate that modulation of P2X2 receptor function, such as that evoked by acidification of the extracellular environment during hypercapnia, may contribute to the changes in activity of the VLM respiratory neurones that express these receptors.  (+info)

Resting discharge of human muscle spindles is not modulated by increases in sympathetic drive. (4/562)

There is evidence in experimental animals that, in addition to receiving fusimotor drive, muscle spindles are subject to modulation by the sympathetic nervous system. We examined the validity of this idea in human subjects by recording from muscle spindles in the relaxed ankle and toe extensor muscles during a strong and sustained physiological activation of muscle sympathetic outflow. Unitary recordings were made from 20 primary and 17 secondary muscle spindle afferents via a tungsten microelectrode inserted percutaneously into the peroneal nerve in 10 awake, healthy subjects seated with the legs supported in the extended position. ECG, blood pressure, respiration and calf circumference were also recorded. The majority of the muscle spindles were spontaneously active at rest; a background discharge was induced in four silent spindles by vibrating the tendon. A sustained increase in muscle vasoconstrictor activity, an increase in calf volume and a fall in pulse pressure were produced by subjects performing a 30-40 s maximal inspiratory breath-hold. Despite this strong increase in muscle sympathetic outflow no significant changes occurred in the discharge of either primary or secondary muscle spindle afferents, measured as a change in mean frequency and variability over sequential 5 s epochs and compared with the preceding period of rest. Strong chemoreceptor-driven sympathetic bursts during sustained expiratory breath-holds also failed to modulate the firing of 14 spindle endings. We conclude that a sustained, physiological increase in muscle sympathetic activity causes no detectable change in muscle spindle firing, lending no support to the concept that the sympathetic nervous system can influence the sensitivity of human muscle spindles directly.  (+info)

Assessment of nasal and sinus nitric oxide output using single-breath humming exhalations. (5/562)

Nasal nitric oxide (NO) levels increase greatly during humming compared to silent exhalation. In this study, the physiological and anatomical factors that regulate NO release during humming have been characterised in 10 healthy subjects and in a model of the sinus and the nose. Single-breath humming caused a large initial peak in nasal NO output, followed by a progressive decline. The NO peak decreased in a step-wise manner during repeated consecutive humming manoeuvres but recovered completely after a silent period of 3 min. Topical nasal application of an NO synthase inhibitor reduced nasal NO by >50% but had no effect on the increase evoked by humming. Silently exhaled nasal NO measured immediately after repeated humming manoeuvres was between 5-50% lower than basal silent NO exhalation, suggesting variable continuous contribution from the sinuses to nasal NO. Among the factors known to influence normal sinus ventilation, ostium size was the most critical during humming, but humming frequency was also of importance. In conclusion, humming results in a large increase in nasal nitric oxide, which is caused by a rapid gas exchange in the paranasal sinuses. Combined nasal nitric oxide measurement with and without humming could be of use to estimate sinus ventilation and to better separate nasal mucosal nitric oxide output from sinus nitric oxide in health and disease.  (+info)

Sputum induction leads to a decrease of exhaled nitric oxide unrelated to airflow. (6/562)

Measurement of exhaled nitric oxide (eNO) and analysis of induced sputum are both established noninvasive methods for studying airway inflammation in asthma. Both methods are often used sequentially within short time frames. The aim of the present study was to evaluate the influence of sputum induction on eNO in adults and to follow the kinetics of airway eNO production after induction in relation to forced expiratory volume in one second (FEV1). eNO and FEV1 were measured in 41 adult patients (aged 29 (range 23-50) yrs, 56% male) with asymptomatic atopy or mild asthma (mean FEV1 97.2+/-3% predicted) prior to and immediately after sputum induction with hypertonic saline (4%). Sputum induction with isotonic saline was also performed in 13 subjects (control group). Repeatability of eNO decrease after sputum induction was also studied in 27 patients on separate occasions and kinetics of eNO production after sputum induction were followed over 24 h in another 10 patients. Sputum induction with hypertonic, but not isotonic, saline led to a marked decrease in eNO (log) immediately after the procedure (pre: 3.85+/-0.13 parts per billion (ppb); post: 3.24+/-0.14 ppb). This decrease was shown to be highly reproducible and not related to a fall in FEV1 following sputum induction. While FEV1 returned to baseline within 1 h, decreased eNO levels were observed over 4 h and returned to baseline after 24 h. Hypertonic saline sputum induction leads to a prolonged reduction in exhaled nitric oxide in adult atopics that is reproducible within subjects and not related to a reduction in airflow following sputum induction. This methodological interference should be taken into account when sputum induction and exhaled nitric oxide measurements are performed in the same subject.  (+info)

Spinal stiffness changes throughout the respiratory cycle. (7/562)

Posteroanterior stiffness of the lumbar spine is influenced by factors, including trunk muscle activity and intra-abdominal pressure (IAP). Because these factors vary with breathing, this study investigated whether stiffness is modulated in a cyclical manner with respiration. A further aim was to investigate the relationship between stiffness and IAP or abdominal and paraspinal muscle activity. Stiffness was measured from force-displacement responses of a posteroanterior force applied over the spinous process of L2 and L4. Recordings were made of IAP and electromyographic activity from L4/L2 erector spinae, abdominal muscles, and chest wall. Stiffness was measured with the lung volume held at the extremes of tidal volume and at greater and lesser volumes. Stiffness at L4 and L2 increased above base-level values at functional residual capacity (L2 14.9 N/mm and L4 15.3 N/mm) with both inspiratory and expiratory efforts. The increase was related to the respiratory effort and was greatest during maximum expiration (L2 24.9 N/mm and L4 23.9 N/mm). The results indicate that changes in trunk muscle activity and IAP with respiratory efforts modulate spinal stiffness. In addition, the diaphragm may augment spinal stiffness via attachment of its crural fibers to the lumbar vertebrae.  (+info)

Respiratory muscle strength training with nonrespiratory maneuvers. (8/562)

The diaphragm and abdominal muscles can be recruited during nonrespiratory maneuvers. With these maneuvers, transdiaphragmatic pressures are elevated to levels that could potentially provide a strength-training stimulus. To determine whether repeated forceful nonrespiratory maneuvers strengthen the diaphragm, four healthy subjects performed sit-ups and biceps curls 3-4 days/wk for 16 wk and four subjects served as controls. The maximal transdiaphragmatic pressure was measured at baseline and after 16 wk of training. Maximum static inspiratory and expiratory mouth pressures and diaphragm thickness derived from ultrasound were measured at baseline and 8 and 16 wk. After training, there were significant increases in diaphragm thickness [2.5 +/- 0.1 to 3.2 +/- 0.1 mm (mean +/- SD) (P < 0.001)], maximal transdiaphragmatic pressure [198 +/- 21 to 256 +/- 23 cmH2O (P < 0.02)], maximum static inspiratory pressure [134 +/- 22 to 171 +/- 16 cmH2O (P < 0.002)], maximum static expiratory pressure [195 +/- 20 to 267 +/- 40 cmH2O (P < 0.002)], and maximum gastric pressure [161 +/- 5 to 212 +/- 40 cmH2O (P < 0.03)]. These parameters were unchanged in the control group. We conclude that nonrespiratory maneuvers can strengthen the inspiratory and expiratory muscles in healthy individuals. Because diaphragm thickness increased with training, the increase in maximal pressures is unlikely due to a learning effect.  (+info)

Fractional exhaled nitric oxide (FeNO) measurement is an important noninvasive tool for evaluating eosinophilic inflammation of the airways. However, measurement of online FeNO in elderly people may not be possible if they are unable to perform the expiratory maneuver. The offline FeNO test is an alternative method that obviates the need for the expiratory maneuver. Adult asthma patients were enrolled and assigned to one of two age groups: group 1, aged >65 years old (n = 29), and group 2, control group, aged 20‐65 years old (n = 27). Online and offline FeNO measurements were performed for all patients. There were no significant differences in pulmonary function parameters (forced expiratory volume in 1 second [FEV1], percentage of predicted FEV1, and FEV1/forced vital capacity [FVC]) between the two groups but group 1 had significantly lower Asthma Control Test scores. There was a high correlation between online and offline FeNO levels (r = 0.908; p < 0.001). There was significantly higher ...

BACKGROUND: Factors affecting fractional exhaled nitric oxide (FeNO) in early childhood are incompletely understood. OBJECTIVE: To examine the relationships between FeNO and allergic sensitization, total IgE, atopic dermatitis, rhinitis, asthma, and lung function (spirometry) in children. METHODS: Children at high risk of asthma and other allergic diseases because of parental history were enrolled at birth and followed prospectively. FeNO was measured by an online technique at ages 6 and 8 years. Relationships among FeNO, various atopic characteristics, and asthma were evaluated. RESULTS: Reproducible FeNO measurements were obtained in 64% (135/210) of 6-year-old and 93% (180/194) of 8-year-old children. There was seasonal variability in FeNO. Children with aeroallergen sensitization at ages 6 and 8 years had increased levels of FeNO compared with those not sensitized (geometric mean; 6 years, 10.9 vs 6.7 parts per billion [ppb], P | .0001; 8 years, 14.6 vs 7.1 ppb, P | .0001).

Next, multiple flow volume tests are performed. First, all of the injectors are flow tested in both a static (wide open) and a dynamic (pulsed) mode. These are timed tests and range from 15 to 30 seconds. The results are noted for comparison after the cleaning process. As you can see from this illustration, the injectors can have a wide range of flow volume. This shows that these injectors are in need of cleaning and the engine they came from would not have been running as smoothly or efficiently as it would have if all of the injectors were flowing the same volume.. ...
The Topographic Wetness Index (TWI), also called Compound Topographic Index (CTI), is a steady-state wetness index. In some areas, TWI has been shown in some study areas to predict solum depth (i.e., Gessler et al., 1995). It involves the upslope contributing area (a), a slope raster, and a couple of geometric functions. The value of a for each cell in the output raster (the CTI raster) is the value in a flow accumulation raster for the corresponding DEM. Higher CTI values represent drainage depressions, lower values represent crests and ridges.. Things to consider carefully: FlowAcc and Slope. How you calculate each will strongly affect TWI values. Catchment area (flow accumulation) can be calculated at least 3 ways (i.e., D8, D-infinity, Triangular multiple flow). Slope calculations also can take different forms (i.e., local slope of a pixel, max or min slope generated using a small neighborhood around each pixel, etc.). See referenced articles.. CTI = ln(a/tan B ...
FENO is used in epidemiological studies as a non-invasive marker of airway inflammation. Some patients do not manage to fulfill the measurement criteria. The objective was to examine if there are any differences between subjects that do and do not manage to perform a correct FENO measurement, mainly relating to respiratory disease and differences in lung function.. The Adonix-cohort comprises a general population sample of 6,296 subjects (52% women), aged 25 to 75 years. They have all been examined with FENO (NIOX, Aerocrine™), lung function, questionnaires and blood samples. To fulfill the measurement criteria for FENO the subjects had to exhale at a 50 mL/s ±10% (mean level 45-55 mL/s and allowed instant flow 40-50 mL/s) during the last 3 seconds of the exhalation, in accordance to international guidelines.. 217 subjects (3.4%, 67% women) were unable to perform a correct test. These subjects were characterized by significantly lower lung function; FVC 3.6 vs 4.2 L (p,0.001) and FEV1 2.8 vs ...
A water trap is connected to a cannula which has a substantially constant internal diameter and which communicates moisture laden patient exhalations therethrough to an analyzer. The trap includes a body having a recess adapted for receiving a water absorbing compound which has an aperture therethrough for communicating dried exhalations to the analyzer. A second recess in the body is adapted for receiving another water adsorbing compound which similarly has an aperture of same diameter. When the first compound becomes substantially saturated and thereby permits moisture laden exhalations to pass therethrough, then the second compound absorbs those exhalations and swells for thereby closing its aperture and preventing communication of moisture laden exhalations to the analyzer.

Controls the variable expiration feature, which allows items to expire a little earlier than the stated expiration time to help prevent cache miss stampedes.. Value is between 0.0 and 1.0, with 0.0 meaning that items expire exactly when specified (feature is disabled), and 1.0 meaning that items might expire anytime from now until the stated expiration time. The default is 0.0. A setting of 0.10 to 0.25 would introduce a small amount of variation without interfering too much with intended expiration times.. The probability of expiration increases as a function of how far along we are in the potential expiration window, with the probability being near 0 at the beginning of the window and approaching 1 at the end.. For example, in all of the following cases, an item might be considered expired any time between 15 and 20 minutes, with about a 20% chance at 16 minutes, a 40% chance at 17 minutes, and a 100% chance at 20 minutes.. ...
It takes a bit to get close enough to get a good picture - but even from beyond visible range, it soon becomes apparent that the transmission is from a very small piece of the probe - specifically, the antenna, removed from within the probe and with just enough power to transmit something. This is inconsistent with being fried or crushed. ...

Stimulated inflammatory cells release large amounts of hydrogen peroxide (H2O2). Breath condensate H2O2 has been shown to be elevated in stable asthmatic children, chronic obstructive pulmonary disease and intubated adult respiratory distress syndrome. In cystic fibrosis airways, where neutrophilic inflammation dominates, it is postulated that H2O2 in breath condensate would be elevated and may be used as a marker of airways inflammation. Expired breath condensate was collected from 16 clinically stable cystic fibrosis (CF) patients (mean age 25.3 yrs, mean forced expiratory volume in one second (FEV1) 50.2%) and 14 normal subjects (mean age 29.9 yrs). Total plasma leukocyte, neutrophil, monocyte and eosinophil counts and lung function were also measured on the day of collection. A method of breath condensate collection excluding the confounding factors of nasal air and saliva contamination was validated and used and H2O2 measured fluorometrically using an optimized assay. The median level of H2O2

AU - Ogawa, Hiroto. AU - Kobayashi, Hirosuke. AU - Takizawa, Naosada. AU - Tanishita, Kazuo. PY - 1998. Y1 - 1998. N2 - A new nitric oxide (NO) selective electrode was developed. The tip diameter of the NO electrode is less than 10 μm. A working and a reference electrodes are located coaxially at the tip of the NO electrode. A stable NO donor SNAP (S-nitroso-N-acetyl-DL-penicillamine) and a putative NO scavenger hemoglobin (Hb) was used to examine the response of the electrode. Considering the instantaneous concentration of NO secretion previously reported in biological systems, 0.1, 1 μM NO solution was used to calibrate the electrode. From the result of the test of the electrode with SNAP and Hb, we confirmed this microcoaxial NO electrode can detect NO released from SNAP directly and continuously. From the ...
This study investigated whether or not there was an overall difference in the pulmonary oxidative marker, 8-isoprostane (PGF2-a), found in exhaled breath condensate, during pregnancy versus the non-pregnant state. The utility of this information was important secondary to the effect of maternal asthma on pregnancy and outcome, as it has been demonstrated in past studies that overall pregnant females with asthma have been shown to have an increased risk of exacerbation requiring medical intervention.The primary goal of this study sought to determine if there is a difference in PGF2a levels in the exhaled breath condensate of pregnant versus non-pregnant females. In order to achieve this goal a cross-sectional study was performed consisting of two groups and were compared to one another. A group of 16 healthy, non-pregnant females aged 18-35 years old was compared to a group of 6 healthy, pregnant females in their third trimester of pregnancy. Both groups exhaled breath condensate was collected and 8
An early and accurate diagnosis can be very important for cancer sufferers. Having the cancer spotted early is one of the things that can help put a cancer sufferer in as strong of position as possible to fight the cancer. Thus, finding methods to help with the diagnosing of cancer is a remarkably important research objective.. A recent study indicates that a rather unconventional, and simple, method may be able to help doctors when it comes to diagnosing lung cancer.. In the study, Italian researchers had the participants (some of who had lung cancer and others of who did not) undergo a breath temperature test. The test simply involved the use of a breath thermometer.. The researchers made a rather surprising finding. They found that breath temperatures were higher among the individuals with lung cancer than they were for those without the cancer. They further found that breath temperature tended to go up as a persons lung cancer became more developed.. Based on these findings, the researchers ...
Evidence-based recommendations on the NIOX MINO, NIOX VERO and Nobreath devices to measure fractional exhaled nitric oxide concentration in asthma
Background:, Fractional exhaled nitric oxide (FENO), a marker of eosinophilic airway inflammation, is easily measured by noninvasive means. The objective of this study was to determine the cost-effectiveness of FENO measurement using a hand-held monitor (NIOX MINO), at a reimbursement price of 23, for asthma diagnosis and management in the UK. Methods:, We constructed two decision trees to compare FENO measurement with standard diagnostic testing and guideline recommendations for management. For asthma diagnosis, we compared FENO measurement with lung function and reversibility testing, bronchial provocation and sputum eosinophil count. For asthma management, we evaluated the impact on asthma control, including inhaled corticosteroid use, exacerbations and hospitalizations, of monitoring with FENO measurement vs symptoms and lung function as in standard care. Resource use and health outcomes were evaluated over a 1-year time frame. Direct costs were calculated from a UK health-care payer ...
Second baseman Robinson Cano is battling a bruise between the thumb and forefinger on his left hand, the Mariners confirmed Friday when he wasnt in the lineup for a second straight game.. I feel better than I felt yesterday (Thursday), Cano said. Maybe tomorrow (Saturday, back in the lineup), but thats up to the manager.. The injury occurred earlier this week on a swing when the bat jammed back into the soft webbed area between the thumb and forefinger. Club officials privately indicate Cano should return by the end of the weekend.. Im just going to leave him out (today), manager Lloyd McClendon said prior to the series opener against Detroit at Safeco Field. Hes going to be day to day. Hes not in the lineup today.. Well see how hes feeling (on Saturday). Its nothing serious. He has a little soreness in there in the muscle area.. Cano is batting .327 with a .371 on-base percentage and a .420 slugging percentage. He has two homers and 31 RBIs in 52 games. No player has appeared ...

An exhalation valve for inhalation therapy includes a base member provided with an exhalation port encircled by a valve seat for a valve closure disc, the center of which is connected to the inner end of a pin extending outwardly away from the disc and slidably mounted in a sleeve spaced from the disc. The sleeve is held rigidly by a support connected with the base member. A number of Constant-Force Compression coil springs extend between the sleeve and disc and are bowed outwardly away from the pin. The ends of the springs are connected with the sleeve and closure disc to urge the disc toward the valve seat. The springs exert a substantially constant pressure against the disc as it is moved outwardly away from the valve seat by air flowing out through the valve port.

TeraBAT receives patent for breath analysis that can detect diseaseGunbarrel-based TeraBAT Inc. has received a patent for what it calls its breakthrough breath analysis technology.
The volumes of both TEW and EBC increased significantly with Vm. The volume of EBC varied between 627 μl and 1358 μl for a 6 minute collection in the Vm range 7.5-22.5 l/min. This indicates that, for this collection device with subjects breathing at a typical resting Vm of 10 l/min, a 6 minute collection would generate a sample of approximately 900 μl. The volume of TEW was significantly higher than the volume of EBC throughout the Vm range studied. This indicates that the condenser efficiency is far from 100% (range 40-29%). It would be reasonable to suppose that this inefficiency also applies to the trapping of aerosolised droplets and that a device with improved efficiency would yield an increased quantity of solutes, thereby enhancing the sensitivity of this technique. A mean reduction of 962 ml in Vt was associated with a 15% reduction in TEW for the same Vm; however, no corresponding effect was seen on solute dilution. This would imply that, at lower Vt, proportionally less solute is ...
You may have noticed that at Pran Yoga Reading there is a prevailing emphasis on breath work. On a physical level there are two main reasons why we teach lengthened exhalation during yoga practice. It provides us with both physical and psychological benefits.. There is more in a simple breath than we may realise. Firstly the oxygen we breath acts as fire of life, burning the nutrients in the system and turning them into energy which we need to live and interact with the world. Without oxygen body cells would die within minutes of being generated. Secondly, the process of exhalation also allows the body to dispose of carbon dioxide and other waste gases that our body produces.. The exchange of gases takes place though the air sacs known as alveoli. A minute network of blood vessels called capillaries surrounds each sac. It is through these capillaries that oxygen enters the bloodstream and is distributed throughout the body. Carbon dioxide is removed through the alveoli from blood travelling in ...

Second base and catcher are the two hardest positions to get better than average offensive players. Cano is an All-Star 2B. The Yankees would have to be crazy to trade him for a AA catching prospect. I might trade Cano for C Ronny Paulino of the Pirates straight up (131 games, .310/.360/.394, age 25, +fielder, +arm) but never a prospect. Robinson Cano can play in NY and is very good. If I were Cashman Id consider Cano a building block of the lineup and look elsewhere to make a deal.. I love Melky but OFs are easy to come by and the Yankees can always sign someone the caliber of Johnny Damon for $$$. There are only a handful of 2B and Cs who can hit. You cant necessarily buy 2B and Cs on the open market like OFs. If Cashman is going to deal youth (I dont think he is) I think it will be Cabrera, not Cano, to leave ...
RATIONALE: Collecting and storing samples of blood and exhaled breath from patients with cancer and from healthy participants to study in the laboratory
In order to properly evaluate different algorithms for computing the total contributing area (TCA) and specific contributing area (SCA) from DEMs, it is important to have mathematical test surfaces for which these quantities can be computed in closed form. In previous work, the inverted cone and inclined plane have been used for this purpose because they are the only mathematical surfaces for which closed- form results were available. Note that the various algorithms differ most in terms of how well they work on divergent topographic surfaces where streamlines diverge, and several different algorithms based on multiple flow directions have been developed for this case. The purpose of this paper is to show how TCA and SCA can be computed mathematically and to provide several new examples of test surfaces for which results can be given in closed form. These new results are then used to test the mass flux method for computing TCA and SCA from DEMs ...
What is interesting is Canos sudden discovery that the team he chose to cast his lot with is not very good. It is the exact same scenario to what his idol and adviser Alex Rodriguez discovered his first year in Texas in 2001 after signing his then-record $252 million deal with the Rangers. Back then, Tom Hicks, the idiot Texas owner who gave A-Rod more than $100 million more than any other team was offering, promised him he would have input in all his teams player personnel decisions. As such, A-Rod was in on all the calls with the scouts during his time in Texas and, like Cano last week, would frequently make his recommendations to Hicks. He was also an instantly privileged player who, unlike any of his teammates, could act like the general manager. It was shortly after the All-Star break in 2001 when A-Rod started referring to the Rangers as 24 kids and me. Still, it took him three years to negotiate his own trade out of Texas, first to the Red Sox (which the players union rejected) and ...

RESULTS: The median FENO peak was 2.69 ppb, and the median FENO plateau was 1.57 ppb. The coefficients of repeatability between the 2 consecutive measurements for FENO peak and FENO plateau were 0.74 and 0.59, respectively. The intraclass coefficient between subjects within the cohort was 0.988 (95% CI 0.975-0.994, P , .001) for FENO peak and 0.991 (95% CI 0.982-0.996, P , .001) for FENO plateau. We found that the FENO peak was directly correlated with minute ventilation, but we did not find a direct relationship between the FENO peak concentration, exhaled NO output, or pulmonary NO excretion and respiratory severity score. ...
