Effect of inhaled budesonide therapy on lung function in schoolchildren born preterm. (1/16)

We investigated the effect of inhaled glucocorticoid (GC) on bronchial obstruction and on bronchial lability in schoolchildren born preterm. Twenty-one children with bronchial obstruction, increased responsiveness to a beta2-agonist, and/or increased diurnal variation in peak expiratory flow (PEF) were selected for an open longitudinal study of the value of inhaled GC. None of these children had an earlier diagnosis of asthma or current GC treatment. Eighteen children with median (range) birth weight 1025 (640-1600) g and gestational age 28 (24-35) weeks, age at study 10.1 (7.7-13) years, were treated with inhaled budesonide in initially high (0.8 mg m(-2) day(-1) for 1 month) and subsequently lower dose (0.4 mg m(-2) day(-1) for 3 months). Daily symptom scores were recorded. Spirometric values were measured in the clinic at the beginning and end of each treatment period. At home, children used a data storage spirometer. After treatment with budesonide for 4 months, spirometric values in the clinic did not significantly change. The median forced expiratory volume in 1 sec (FEV1) was 74% of predicted both at entry and after budesonide treatment. However, the median number of > or = 20% diurnal change in PEF values at home decreased during treatment. According to the present study, inhaled budesonide for 4 months had no significant effect on basic lung function but may decrease bronchial lability in schoolchildren born preterm.  (+info)

Spontaneous pneumothorax: pragmatic management and long-term outcome. (2/16)

We prospectively considered 65 patients admitted for a spontaneous pneumothorax (SP) to describe the pragmatic management of SP, the first recurrence-free interval after medical therapeutic procedure and to specify the first recurrence risk factors over a 7-year period in these patients treated medically. The treatment options were observation alone (9%), needle aspiration (6%), small calibre chest tube (Pleurocatheter) drainage (28%) or thoracic tube drainage (49%), and pleurodesis with video-assisted thoracic surgery procedure (8%). Duration of the drainage and length of hospital stay were shorter in the Pleurocatheter group than in the thoracic tube group (P < 0.01). Among the 47 patients (72%) with a first SP and treated medically, nine patients (19%) had a first homolateral recurrence (FHR) during a mean follow-up of 84+/-13 months. Recurrence-free intervals ranged from 1 to 24 months (mean +/- SD: 9.3+/-8.4 months). FHR cases were more frequent in the Pleurocatheter group (P < 0 04). Analysis of potential risk factors showed that the patient's height and a previous homolateral SP episode are independent recurrence risk factors.  (+info)

The biphasic spirogram: a clue to unilateral narrowing of a mainstem bronchus. (3/16)

Two patients with narrowing of a mainstem bronchus each showed two unusual functional features that are likely to be characteristic of this condition. The maximum inspiratory flow-volume curve showed an end inspiratory "tail" and the forced expiratory spirogram had a biphasic shape with normal initial curvature but a "straight line" appearance in later expiration. In one patient relief of the bronchial stenosis by the insertion of a stent restored normal contours to the spirogram and flow-volume curves.  (+info)

Associations of dairy intake with CT lung density and lung function. (4/16)

OBJECTIVE: Dairy products contain vitamin D and other nutrients that may be beneficial for lung function, but they are also high in fats that may have mixed effects on lung function. However, the overall associations of dairy intake with lung density and lung function have not been studied. METHODS: We examined the cross-sectional relationships between dairy intake and computed tomography (CT) lung density and lung function in the Multi-Ethnic Study of Atherosclerosis (MESA). Total, low-fat, and high-fat dairy intakes were quantified from food frequency questionnaire responses of men and women who were ages 45-84 years and free of clinical cardiovascular disease. The MESA-Lung Study assessed CT lung density from cardiac CT imaging and prebronchodilator spirometry among 3965 MESA participants. RESULTS: Total dairy intake was inversely associated with apical-basilar difference in percent emphysema and positively associated with forced vital capacity (FVC) (the multivariate-adjusted mean difference between the highest and lowest quintiles of total dairy intake was -0.92 [p for trend = 0.04] for apical-basilar difference in percent emphysema and 72.0 mL [p = 0.01] for FVC). Greater low-fat dairy intake was associated with higher alpha (higher alpha values indicate less emphysema) and lower apical-basilar difference in percent emphysema (corresponding differences in alpha and apical-basilar difference in percent emphysema were 0.04 [p = 0.02] and -0.98 [p = 0.01] for low-fat dairy intake, respectively). High-fat dairy intake was not associated with lung density measures. Greater low- or high-fat dairy intake was not associated with higher forced expiratory volume in 1 second (FEV(1)), FVC, and FEV(1)/FVC. CONCLUSIONS: Higher low-fat dairy intake but not high-fat dairy intake was associated with moderately improved CT lung density.  (+info)

Bronchial reactivity to inhaled histamine and annual rate of decline in FEV1 in male smokers and ex-smokers. (8/16)

We examined the relations between bronchial reactivity, baseline FEV1, and annual decline of height corrected FEV1 (delta FEV1/ht3) over 7.5 years in 227 men (117 smokers, 71 ex-smokers, and 39 non-smokers). Men with a clinical diagnosis of asthma or receiving bronchodilator treatment were excluded. Bronchial reactivity was determined as the provocation concentration (PC20) of inhaled histamine sufficient to reduce FEV1 by 20%; subjects were divided into reactors (PC20 less than or equal to 16 mg/ml) and non-reactors (PC20 greater than 16 mg/ml). Thirty per cent of smokers, 24% of ex-smokers, and 5% of non-smokers were reactors. When smokers who were reactors were compared with non-reactors, the reactors showed a lower baseline FEV1 as percentage predicted in 1981-2 (85% v 108%), and a faster delta FEV1/ht3 (14.1 v 9.2 ml/y/m3). Baseline FEV1 correlated with PC20 in both smokers (rs = 0.51) and ex-smokers (rs = 0.61), and all 15 subjects with an FEV1 under 80% of the predicted value were reactors. In ex-smokers delta FEV1/ht3 was similar in reactors and non-reactors (m 9.0 v 7.4 ml/y/m3), despite significant differences in baseline FEV1. When analysis was confined to men with a baseline FEV1 over 80% predicted, the prevalence of reactors was significantly increased among smokers and slightly increased among ex-smokers compared with non-smokers, though the mean FEV1 was higher in the non-smokers. Bronchial reactivity was not increased in smokers aged 35 years or less. In smokers delta FEV1/ht3 was faster in those with a personal history of allergy (usually allergic rhinitis), but was not related to a family history of allergic disease, total serum immunoglobulin E level, absolute blood eosinophil count, or skinprick test score. delta FEV1/ht3 was also faster in all subjects taking beta blocker drugs. Thus increased bronchial reactivity was associated with accelerated decline of FEV1 in smokers. Although the association could be a consequence of a lower lower baseline FEV1, a trend towards increased reactivity was found in smokers with normal baseline FEV1 and delta FEV1/ht3 was dissociated from increased reactivity in ex-smokers. These findings are compatible with the "Dutch hypothesis," but the association between allergic features and accelerated delta FEV1/ht3 was relatively weak, and increased reactivity may follow rather than precede the onset of smoking.  (+info)

We have calculated the effective time (t eff) of the forced expiratory spirogram in healthy non-smokers, in patients with simple chronic bronchitis, and in patients with chronic obstructive lung disease. Effective time was obtained by dividing the area underneath the forced expiratory spirogram by the forced vital capacity (FVC) and is equal to the time constant of lung emptying if the FVC-time curve is a single exponential. In 75 healthy non-smoking adults, t eff showed a linear increase with age but no difference between the sexes. In 37 patients with low forced expiratory volume in one second (FEV1)/FVC ratios, t eff, as expected, was increased. In 19 subjects with simple chronic bronchitis and normal FEV1/FVC ratios, t eff was longer than or at the upper limit of 2 SE above the mean for healthy subjects of the same age. A comparison of t eff with FEV1/FVC suggested that in most normal subjects and patients the forced expiratory spirogram was a multiple exponential and that t eff was a more ...
It has been proposed that increased production of IgE, a feature of atopy, is a cause of the non-specific bronchial hyper-reactivity that is characterisitc of asthma. This hypothesis was examined by selecting groups of subjects with asthma or rhinitis and a group of healthy control subjects and studying the relationship between their bronchial histamine reactivity and their atopic status. In none of the groups tested was there a significant association between the degree of bronchial histamine reactivity and either the serum level of total IgE or the number of extracts of aeroallergens giving positive prick test reactions.

CT Lung Screenings Now Available for only $99* A randomized clinical trial conducted by the American College of Radiology Imaging Network and sponsored by the National Cancer Institute, released its results in November 2010. The trial showed screening current and former heavy smokers with CT scans reduced their risk of dying from lung cancer by 20%. With 100 million smokers and ex-smokers in the US and over 160,000 Americans dying early from lung cancer, CT lung screening could potentially save thousands of lives annually by catching tumors at an even earlier, more treatable stage than chest x-rays. Chest x-rays only have the capability of detecting tumors greater than 1 cm in size. A CT scan detects tumors significantly smaller than 1 cm in size. CT Lung Screenings can also provide information to physicians on cardiovascular disease, emphysema, and other pulmonary diseases.

Discrepancies are frequently noted between the degree of lung involvement as shown by the roentgenogram and the severity of subjective symptoms of the patient. With the advent of pulmonary functional studies, such as bronchospirometry and pulmonary artery catheterization, discrepancies were still observed between the degree of functional impairment and the degree of involvement on the roentgen-ray picture. It is also well known that there is often very little correlation between cardiorespiratory insufficiency that is observed in silicotics and the degree of pulmonary involvement as seen both on roentgenographic picture and at postmortem examination.

Because of the dynamic nature of the cases, the examiner cannot give you a time warning, but will keep track of the time. Instead, you should listen for cues from the examiner that tell you whether you should slow down or speed up. For example, "the nurse is asking what you would like to do next," is a cue that you should move a little more quickly. "The nurse asks you to repeat your orders," is a cue that the examiner needs more to time to record your actions. Its important to demonstrate effective time management during each case. Cases are designed to be manageable within the time limits, and the examiners help by guiding the pace of each encounter, so you have enough time to finish. You are not scored on speed, so be responsive to examiners efforts to either slow down or move the case along.. ...

A number of mechanisms have been proposed as the basis for the relationship between nonspecific airway responsiveness and prechallenge pulmonary function. Because resistance to flow through a tube is inversely proportional to the radius to the fourth power, a given degree of bronchoconstrictor-induced circumferential airway narrowing can be expected to cause a proportionally larger increase in airway resistance in a narrow airway than in a wider airway. Intersubject differences in the distribution of resistance along the bronchial tree may influence both the pattern of aerosol deposition and the relative impact on total airway resistance of bronchoconstriction at particular sites such as the peripheral airways. Airway hyperresponsiveness may result in heightened bronchomotor tone prior to challenge and thereby be correlated with reduced prechallenge pulmonary function. The convention of expressing responsiveness in terms of percentage of change in FEV, (eg, PD20FEV,) imposes a mathematical ...

AU aspects of his schedule were shifted simultaneously in this protocol including the sleep-wake cycle, meal times, activity, posture, and interaction with staff, precluding identification of the effective time signal, but collectively at least they were able to induce a phase advance. Other attempts to entrain circadian rhythms in blind people using a "potential complex "zeitgeber" including exercise (bicycle riding, 50 W over 15 mins), a strict social routine, a cold ...

This paper focuses on the signal preemption control of|i| emergency vehicles |/i|(EV). A signal preemption control method based on route is proposed to reduce time delay of EV at intersections. According to the time at which EV is detected and the current phase of each intersection on the travelling route of EV, the calculation methods of the earliest start time and the latest start time of green light at each intersection are given. Consequently, the effective time range of green light at each intersection is determined in theory. A multiobjective programming model, whose objectives are the minimal residence time of EV at all intersections and the maximal passing numbers of general society vehicles, is presented. Finally, a simulation calculation is carried out. Calculation results indicate that, by adopting the signal preemption method based on route, the delay of EV is reduced and the number of society vehicles passing through the whole system is increased.

Why Low Dose CT Vs. Standard CT or a Chest X-ray?. Standard CT scans of the chest provide more detailed pictures than chest x-rays and are better at finding small abnormalities in the lungs. Low-dose CT of the chest uses lower amounts of radiation than a standard chest CT but it is more than the dose from a chest x-ray. So LDCT is a balance, offering the detail closer to standard CT with the radiation dose closer to a chest x-ray.. Do all imaging centers provide Low Dose CT Lung Cancer Screening?. No. Not all imaging centers have Low Dose CT scanners. Screening should only be done at facilities that have the right type of CT scanner and have developed a proper Low Dose CT imaging protocol specific for Lung Cancer Screening. University Medical Imaging was the first to provide Low Dose CT to the Rochester Community in 2006 and is the community leader in reduced dose CT.. Is this test right for me?.

Risk factors for the development of BPF after pneumonectomy include anatomic, technical, and patient factors (Table 82-1).4,5 Right pneumonectomy is associated with a fourfold to fivefold higher incidence of BPF than left pneumonectomy, likely related to anatomic differences between the right and left mainstem bronchi.6 A right pneumonectomy stump has minimal mediastinal coverage of the bronchial stump compared with a left-sided stump, which retracts underneath the aorta into the mediastinum when properly fashioned (Fig. 82-1). The right mainstem bronchus is also oriented much more vertically than the left, which permits secretions to pool in the bronchial stump. Finally, the vascular supply to the left mainstem bronchus is augmented by direct vascular branches as the bronchus passes behind the aorta. The blood supply on the right travels from the trachea via local branches in the subcarinal space, which are often disrupted by dissection and lymph node removal. ...
Devices, systems and methods for occluding blood vessels include a deployable constrictor having opposed pressure-applying portions, a delivery shaft configured to intravaginally advance the constrictor to the patients cervix, a location sensor configured to detect a blood vessel, a deployment member for deploying the constrictor about the patients cervix, and optionally a guide. The constrictor has a first configuration to receive a cervix and a second configuration to apply pressure to the cervical area to occlude a uterine artery by compression from the pressure-applying members. The pressure-applying members may be released from the cervix after a limited therapeutically effective time. The invention finds use in, for example, treating uterine disorders and conditions which may be treated by occlusion of the uterine arteries, such as uterine fibroids, dysfunctional uterine bleeding, post-partum hemorrhage, and bleeding associated with caesarian sections.
Unilateral airway occlusion permits measurement of single lung function. Since the results suggest that the occluded lung influences the mobility of the contralateral hemithorax, we wanted to test this hypothesis. In eight healthy subjects, we measured, using computed tomography, lung parenchymal area and inner rib cage parasagittal and transverse diameters at three different levels and at maximal inspiration and expiration. These measurements were made without and during balloon occlusion of one mainstem bronchus at residual volume (RV) and at total lung capacity (TLC). Unilateral occlusion at RV reduced the ipsilateral diameters in maximal inspiration, but the increase during inspiration was still 39-50% of that without occlusion. The inspiratory increase in contralateral diameters was reduced to 64-80% of the increase without occlusion. Occlusion at TLC reduced the expiratory decrease in ipsilateral diameters to 37-57% of that without occlusion. The expiratory decrease on the contralateral ...
The cover features an image of RNA sequencing (RNA-Seq) results for a processed transcript of the mucin 5AC gene (MUC5AC, foreground), a potentially important smoking- and lung cancer-related gene. The output is superimposed on an image of human ciliated columnar bronchial epithelial cells obtained by endoscopic brushings of the mainstem bronchi (100X, modified Wright-Giemsa stain). The MUC5AC read coverage plot displays reads aligning to the transcript normalized by the total number of reads on the y-axis versus the genomic coordinates on the x-axis. The MUC5AC processed transcript shows marked upregulation in healthy current smokers compared with never smokers and downregulation in smokers with lung cancer compared with smokers having benign lung disease. The detection of MUC5AC expression highlights the advantage of RNA-Seq because the transcript is not annotated in RefSeq and there are no probes on the Affymetrix Exon 1.0 ST microarray to interrogate it. RNA-Seq is one of several ...
There is alveolar, lobar consolidation of the left caudal and right cranial lung lobes. There is a diffuse bronchointerstitial pattern with nodular components in the remainder of the lung. The heart appears normal in size. On the d/v projection, there is widening of the mainstem bronchi at the hilus suggesting hilar lymphadenopathy. On the lateral projection, there is a focal hepatomegaly causing curving of the gastric axis ...
ABSTRACT Particle deposition on indoor surfaces has lately received great attention due to increasing concern about the effects of particle exposure on human health. In this study, we developed an easy and low-cost method of measuring the deposition amounts of different-sized particles and evaluated it through particle concentration measurement and theory calculation. First, a clean charge-coupled device (CCD) chip was exposed to air in order to receive the deposition of airborne particles. After sedimentation, images generated by the CCD of the deposited particles were analyzed, and the quantity of particles in each size range (> 2 µm) was identified based on the unique pixel sizes. Using a particle counter and a dust monitor, we also measured the concentrations of airborne particles with different sizes near the chip during sedimentation and compared them with the numbers of settled particles. The results show that the particle deposition can be quantified with this method and that a positive

While the Half Dome hike was the definite highlight of the retreat, there was of course more to it than that. Didnt leave Berkeley until around 1:30 pm. Due to damn traffic and various stops, we didnt get to the lodge until 6 pm. At first was pretty boring, people were all watching damn police chase show. It got interesting after more people got there, everyone started talking and doing various things. Somehow we managed to fit 35 people into a suit designed for (and paid for) 14 ppl (21 sleeping bags--- WOW) We basically assigned rooms for sleeping based on who was actually going to do what: Half Dome or off-roading. 23 ppl were to do Half Dome. We got to bed around 11:30 in anticipation of having to get up at 5 am. I didnt sleep very much that night and im not sure why. Perhaps it was the random noises i kept hearing or perhaps fear/agony of what we were about to do the next day. Anyway in the morning we actually all got up at 5 am and were out of the place at 6 am as planned. We split up ...

This study introduces a new equal area method for the calculation, representation, and visualization of physiologic dead space based on a principle similar to the Fowler equal area method. The new method is analytically identical to the Bohr-Enghoff equation and yields numerical results that do not differ significantly from those calculated directly by the Bohr-Enghoff equation. Advantages of this new method include the following: (1) the graphical representation on a linear scale of the relations between all of the dead space volumes and fractions, including Vdanat, Vdalv, Vdphys, Vt, Vdanat/Vt, Vdalv/Vt, Vdphys/Vt, and Vdalv/Vtalv, which is especially helpful for the visualization of dead spaces during bedside monitoring of patients; (2) the use of a principle similar to that used in the Fowler equal area method, which makes the calculation of anatomical and physiologic dead spaces on the carbon dioxide expirogram consistent; (3) the use of a more straightforward method than the partitioning ...
Tinnitus is the phantom auditory perception of sound in the absence of an external or internal acoustic stimulus. It is a frequent problem which can interfere significantly with the ability to lead a normal life. Tinnitus has been shown to be generated in the brain, as a result of functional reorganization of auditory neural pathways and the central auditory system. These changes are represented by hyper-activity and hyper-synchronicity in the auditory pathway. Treatment remains difficult. Non-invasive brain stimulation methods has shown to be effective in the treatment of chronic tinnitus with moderate effect size. Preliminary data presented on international conferences suggest the use of transcranial random noise stimulation (tRNS) over both auditory cortices as new and highly effective treatment. High-frequency (hf; 100-650Hz) tRNS might be highly effective in tackling hyper-synchronised cell assemblies. Daily Hf-tRNS (2 weeks) will be examined with regard to feasibility, safety and clinical ...
This well known home remedy was one of the first I learned in Naturopathic Medical school years ago and it has proven itself effective time and again for helping my patients get over nasty chest and head colds fast. Although most people know that eating garlic during a cold helps boost the immune system many people dont know the most important ingredient to making this Garlic "trick" work---exposure to oxygen/air, time and crushing of the garlic. Why? Because research has shown that by crushing the garlic one exposes the chemicals inside the cells to air which activates a chain on chemical reactions necessary to create its antibacterial and antiviral components. In this way Garlic chemically acts much like those "hot pockets" one uses when skiing to warm their hands - exposure to air to start the chemical reactions. Research has shown crushed garlic to be bacteriostatic, antiviral and antifungal inhibiting the growth of a wide range of pathogens including Staphylococcus sp., Neisseria ...

From The American Journal of Medicine, 1859, page 379.. "1859, Jan. 5. Improved Spirometer - Dr. S. W. Mitchell exhibited an improved form of spirometer, of which he gave the following description: -. "While conducting some recent researches upon the physical statistics of natives of this country, I was struck with the clumsiness, and, in some cases, with the inaccuracy, of the form of spirometer in common use. This instrument, well known as Hutchinsons spirometer, is accurate in its indications when well made, but is always inconvenient, because it requires to be filled with water, and, on account of its weight and form, is not easily carried from place to place. This latter objection applies equally to all the spirometers I have examined; while most of the instruments on the side of the water are also open to the additional objection of want of accuracy.. "The instrument which I have used in its place is merely a small "dry gasmeter" numbers of which are made in this city by Messrs. Code, ...
iRiver has a huge line of flash-based players with various memory sizes (128MB to 2GB). Some of these players may need an updated firmware in order to play Ogg Vorbis files, see the [http://www.iriveramerica.com/support/ support download page] for that. Note - on older players, only certain bitrates are supported, various problems are reported including reboots, silence and random noise when a VBR Vorbis passes outside the limit (either under 96Kbps or over 225 Kbps). Newer players dont have this limitation. However, please be alerted that many of the newer players, such as the Clix, use the Microsoft MTP transfer protocol exclusively so they only work with Windows, whereas other players may be shipped with MTP, but have alternate non-MTP firmware available for download. Tag support not present on U10/Clix (others also?), so Vorbis files will appear under unknown artist/unknown album. Please note that the H10 model does not (yet?) support ogg, and can operate in both MTP and UMS (mass ...
These little variations endogenous LRTs cause, in protein structure or protein expression, could be a huge driving force behind speciation and diversity! (microRNAs have a role in this too!). Well, weve got a minor problem trying to address the impact of LTRs on gene expression in humans. We do, like, these huge data mining experiments which tell us "OMG LIEK THEIR ALL ACTIVE!"… but then you have to go back by hand to figure out whether the LTR activity is random noise, a minor contributor to gene expression, creating an alternative protein, or the sole promoter for the gene.. A review was just published that consolidates a lot of what we know about ERV LTRs and human genes.. ...

It is well known that patients undergoing bronchoscopy could be less suffering and the procedures could be carried on more smoothly if the patients have adequate sedation and analgesia. The preferred sedative and analgesic drugs are Midazolam and opioid, like Alfentanil or Morphine, which were titrated according to physicians judgment on patients clinical responsiveness. However, due to the pharmacokinetic characteristic of midazolam while used in intravenous injection (onset time 4-6 minutes, effective time 2-4 hours), the effective onset time may be too slow for repeated injection while patients already suffered from the bronchoscopic procedure. It is also noted that when over-sedation occurred the side effects like apnea/hypopnea, hypoxemia, and hypotension could last from dozen minutes to few hours. Although events mentioned above could be handled properly under experienced medical staff, it is still very difficult to predict the oncoming events as the pharmacokinetic effect is variant ...
THURSDAY, Sept. 15, 2016 (HealthDay News) - Spirometers used in primary care offices are frequently inaccurate, according to a study published online Sept. 6 in the Annals of the American Thoracic Society.. Matthew J. Hegewald, M.D., from Intermountain Healthcare in Murray, Utah, and colleagues tested 17 spirometers used in primary care offices with a waveform generator to assess spirometer accuracy. They determined the clinical significance of inaccurate instruments by applying the forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) error from an obstructed waveform to a clinical data set.. The researchers found that only one of the spirometers met the accuracy criteria, with mean errors ranging from 1.7 to 3.1 percent for FVC, FEV1, and FEV1/FVC. Twenty-eight percent of tests were re-categorized from obstructed to non-obstructed when applying the percent error to a clinical data set. Sixty percent of the spirograms reviewed were considered acceptable for clinical use. No ...
Dairy foods and beverages account for about 70% of all dietary calcium intake among Americans. Dozens of epidemiological and randomised controlled trials in adults and children have used dairy products as the principal source of calcium, and have credited dairy intake with preventive benefits on study end points including bone mass, fractures and osteoporosis. A recent meta-analysis of over 270 000 people showed a strong trend for dairy intake protecting against hip fracture; the relative risk (RR) of hip fracture per daily glass of milk was 0.91, 95% CI 0.81 to 1.01.9. In many industrialised nations, milk is often the most cost-effective strategy for achieving recommended levels of calcium intake at a population level. Yet, legitimate concerns exist regarding potential deleterious effects of chronic dairy intake on health.10-16 Dairy foods, on an evolutionary time scale, are relative new-comers to the hominin diet.17 Domestication of cattle, sheep and goats first occurred approximately 11 ...
36 The use of external PEEP in the setting of auto-PEEP may be conceptualized by the "waterfall over a dam" analogy. In this analogy, the presence of dynamic hyperinflation and 10 cmH20 of auto-PEEP is represented in the top panel by the reservoir of water trickling over the dam represented by the solid block. In the middle panel, as long as the external PEEP is less than or equal to the amount of auto-PEEP, the amount of water in the upstream reservoir, representing dynamic hyperinflation, does not increase. However, once the amount of water in the reservoir does increase (bottom panel), dynamic hyperinflation worsens. ...

The monitoring of plants and the verification of process models depend crucially on reliable sets of steady state component and total flow rate data. These measurement data are generally subject to random noise (and possibly systematic errors) and typically violate the process constraints of the system. It is consequently necessary to adjust the data, and also to account for systematic or gross errors in the data prior to this reconciliation procedure, or as part of it, in order to avoid severe impairment of the adjustment process. This can be accomplished by using a back propagation neural net to form an internal representation of the relationship between the distributions of the measurement residuals and the residuals of the process constraints. The major advantage of using neural nets instead of conventional statistical methods, is that neural nets can also be used to detect systematic errors in process systems subject to non-linear process constraints (a common situation in the chemical and ...
Intelligible crosstalk in microwave radio systems employing single-sideband modulation is substantially eliminated by phase-modulating the AM carrier-wave prior to its modulation by the baseband signal. The phase-modulation may comprise a periodic signal, such as a single sinusoidal tone or pseudo-random noise, or it may comprise an aperiodic signal such as a truly random noise. In this latter event, the coding signal is transmitted to the receiving location to ensure proper demodulation of the encoded signal.
The Connectivity Map (CMap) is a database of 1.4 million transcriptional profiles from cell lines treated with small molecule or genetic perturbations. This resource promises to serve as a comprehensive "lookup table" for biology by linking drugs to genes and pathways. However, distinguishing true similarities from random noise within such a large, multidimensional dataset presents significant challenges to result interpretation and hit prioritization. To address these challenges, we took advantage of the fact that different CMap drugs may share the same molecular target or mechanism of action. We hypothesized that grouping drugs into reference pharmacologic classes would yield dramatically more crisp and readily interpretable query results.. In order to successfully group drugs by mechanism of action, standardized drug annotations were required. More than 2,000 CMap compounds were mapped to their known targets by comparing chemical structures to entries in existing public databases or by manual ...

The trachea (windpipe) divides into two main bronchi (also mainstem bronchi), the left and the right, at the level of the sternal angle. The right main bronchus is wider, shorter, and more vertical than the left main bronchus. The right main bronchus subdivides into three segmental bronchi while the left main bronchus divides into two. The lobar bronchi divide into tertiary bronchi. Each of the segmental bronchi supplies a bronchopulmonary segment. A bronchopulmonary segment is a division of a lung that is separated from the rest of the lung by a connective tissue septum. This property allows a bronchopulmonary segment to be surgically removed without affecting other segments. There are ten segments per lung, but due to anatomic development, several segmental bronchi in the left lung fuse, giving rise to eight. The segmental bronchi divide into many primary bronchioles which divide into terminal bronchioles, each of which then gives rise to several respiratory bronchioles, which go on to divide ...
TY - JOUR. T1 - Antihypertensive action of allantoin in animals. AU - Chen, Mei Fen. AU - Tsai, Jo Ting. AU - Chen, Li Jen. AU - Wu, Tung Pi. AU - Yang, Jia Jang. AU - Yin, Li Te. AU - Yang, Yu Lin. AU - Chiang, Tai An. AU - Lu, Han Lin. AU - Wu, Ming Chang. PY - 2014. Y1 - 2014. N2 - The agonists of imidazoline I-1 receptors (I-1R) are widely used to lower blood pressure. It has been indicated that guanidinium derivatives show an ability to activate imidazoline receptors. Also, allantoin has a chemical stricture similar to guanidinium derivatives. Thus, it is of special interest to characterize the effect of allantoin on I-1R. In conscious male spontaneous hypertensive rats (SHRs), mean blood pressure (MBP) was recorded using the tail-cuff method. Furthermore, the hemodynamic analyses in catheterized rats were applied to measure the actions of allantoin in vivo. Allantoin decreased blood pressures in SHRs at 30 minutes, as the most effective time. Also, this antihypertensive action was shown in ...
Using a sensitive single isotope enzymatic assay we measured bronchoalveolar lavage (BAL) fluid histamine in asymptomatic normal (nonallergic), allergic rhinitic, and allergic asthmatic subjects. Normal subjects were found to have little or no detectable amounts of histamine in BAL fluid (11 +/- 11 pg/ml), and few BAL fluid mast cells. In comparison, the allergic rhinitics and allergic asthmatics had much higher amounts of BAL fluid histamine (113 +/- 53 and 188 +/- 42 pg/ml, respectively), and a significantly greater number of BAL fluid mast cells. Furthermore, despite having equivalent baseline pulmonary function values, allergic asthmatics with BAL fluid histamine levels greater than 100 pg/ml required only 7 +/- 2 breath units of methacholine to induce a 20% drop in forced expiratory volume in 1 s (FEV1) (PD20FEV1) while asthmatics with BAL fluid histamine levels less than 100 pg/ml required 49 +/- 19 breath units (P less than 0.05). These data suggest that allergic asthmatics have ongoing ...

1. Twelve non-smoking subjects inhaled capsaicin at three different inspiratory flow rates: 50, 100 and 150 litres/min. Capsaicin was delivered by a breath-actuated dosimeter; inhalations consisted of 0.21-13.6 nmol of capsaicin in doubling amounts given in random order.. 2. The mean number of coughs per challenge decreased with increasing inspiratory flow rate. The difference in cough numbers were significant: 7.7 (95% confidence interval 2.5-12.8) for 50 versus 100 litres/min and 10.9 (95% confidence interval 5.0-16.9) for 100 versus 150 litres/min.. 3. On a separate day, a cough threshold was measured by giving increasing doses of citric acid that were inhaled at 50 litres/min. There was a positive correlation between the sensitivity to capsaicin and the cough threshold to citric acid (r = 0.69, P = 0.01), and also between the cough latencies (r = 0.67, P = 0.02).. 4. The negative relationship between the cough response and the inspiratory flow rate may be caused by increased laryngeal ...
Early buyers will receive 10% customization on reports.. A spirometer is an instrument used to measure the air inhaled into and exhaled out of the lungs. It provides a simple way of measuring lung volume and capacity, and is used in pulmonary tests. It helps in diagnosing respiratory diseases (such as asthma, bronchitis, emphysema, and COPD), shortness of breath, exposure to chemicals at work, lung function before surgery, effect of medication, and progress in disease treatment.. Most spirometers depict a volume time graph and a flow volume graph, which help in examining a patient s pulmonary functions. The application of spirometers has become easier with the help of technological advancements in the field of respiratory care devices. Key factors influencing the growth of the market in the U.S. and Europe are policies mandating the use of respiratory devices, and lack of awareness of respiratory diseases and their symptoms..

ABSTRACT: In statistical practice, rectangular tables of numeric data are commonplace, and are often analyzed using dimension-reduced methods like the singular value decomposition and its close cousin, principal component analysis (PCA). This analysis produces score and loading matrices representing the rows and columns of the original table and these matrices may be used for both prediction purposes and to gain structural understanding of the data. In some tables, the data entries are necessarily nonnegative (apart, perhaps, from some small random noise), and so the matrix factors meant to represent them should arguably also contain nonnegative elements. This thinking, and the desire for parsimony, underlies such techniques as rotating factors in a search for simple structure. These attempts to transform score or loading matrices of ...
I used to teach social statistics in a major Australian university and I find medical statistics pretty obfuscatory. They seem uniformly designed to make mountains out of molehills. Many times in the academic literature I have excoriated my colleagues in psychology and sociology for going ga-ga over very weak correlations but what I find in the medical literature makes the findings in the social sciences look positively muscular. In fact, medical findings are almost never reported as correlations -- because to do so would exhibit how laughably trivial they generally are. If (say) 3 individuals in a thousand in a control group had some sort of an adverse outcome versus 4 out of a thousand in a group undergoing some treatment, the difference will be published in the medical literature with great excitement and intimations of its importance. In fact, of course, such small differences are almost certainly random noise and are in any rational calculus unimportant. And statistical significance is ...

When looking back on this day, well probably remember the big fish, the unseen gulpers after dark and the weight on the rods after setting up on random noises that may or may not have been a brown sucking in our dry flies. The victories are easy to remember but my knees and calves are not so quick to forget the hours of walking up and down the river. My eyes are stinging a bit this morning from staring at riseless water in bright sun trying to see if there were dimples under the trees, in the shade. My back remembers the pounding it took as a result of my mind wishing there were rising fish in the next riffle, around the bend. The Tacoma bears the aftermath of dusty dirt roads and mud from my boots as we stopped at spot after spot roaming up one side and down the other looking for signs of life. Drakes came off from 9am to 3pm and I saw 2 fish, which I promptly put down with pretty good casts. Scott got a decent fish to take his drake in the mid-day sun with an audience of a drifter who had the ...
Things were ok. Judith was cranky - a combination of being tired and teething (those pesky molars are working their way through, and I know its really bothering her), and I did have to take her out of the church during the sermon. Part of the problem was there were too many people for her to look at in the back of the church (I thought ahead on that one, and had the sense to sit as close to an exit as possible... just in case!), and the other part was she just could not find a comfortable spot in my arms. I started out wearing her in the ring sling, much like I do for Sunday morning services, but she was getting pissed by being more restricted in that. Then she got mad because I refused to let her eat my bulletin, and gave her an appropriate toy to gnaw on. She wasnt really noisy up until the sermon, when she started to fuss because she couldnt get comfy. So I got up, took her out into the hallway, and listened to her make random noises (excited screams included) because she made the ...
