BD CompBeads were stained as compensation controls for V450 anti-human CD11b and for FITC anti-human CD35, while pHrodo™ labeled bacteria were used as phycoerythrin (PE) fluorescence to calculate the compensation matrix. The compensation values were calculated automatically by DiVa™ software. The BD High Throughput Sampler (HTS) System was used to run the plate samples. A total of 10,000 events were collected from each sample gated on live cells. Forward scatter and Side scatter were acquired on a linear scale and fluorescence was acquired on a logarithmic scale. PE and fluorescein isothiocyanate (FITC) were excited using 488 nm laser and the emission of fluorescence was collected using

585/42 nm and 530/30 nm filters, respectively. V450 and LIVE/DEAD

Fixable Aqua were excited by 405 laser and fluorescence emission was collected with 450/50 nm and 510/50 nm DF filters. After acquisition, all data were exported as Flow Cytometry Standard format 3.0 Ibrutinib mw files (FCS files) and analyzed by FlowJo (Mac-Version 9.1; Treestar US, Ashland, OR). Differentiated HL-60 cells were dispensed in 96 microtiter plates and incubated with labeled bacteria for 30 min in the presence of specific or unrelated serum and baby rabbit complement, under the same conditions and using the same concentration described for the fOPA. After incubation, cells were washed twice with PBS (centrifuging the plate at 900 rpm for 5 min at 2–8 °C) and fixed with 4% PFA in PBS for 5 min at 2–8 °C. After washing, Trametinib research buy bacteria were pelleted by centrifugation at 900 rpm for 5 min. The plasma membrane was then stained by incubating cells for 30 min at for 4 °C with 100 μl of Alexa Fluor 488-phalloidin (0.16 μM, Molecular Probes) solution or concanavalinA-FITC (Sigma) solution in PBS (2 μg/ml). After washing, cells were suspended in 10 μl of SlowFade Antifade kit (Molecular Probes) and mounted on a glass slide. Images were acquired on a Zeiss LSM 710 laser scanning confocal microscope. Each experiment was performed in triplicate. Data are represented as mean ± SD. Correlations were analyzed by a linear

regression model. Fitting was analyzed with the support of a statistical software (GraphPad Prism 5). The amine-reactive succinimidyl ester of pHrodo™ dye was used to label paraformaldehyde (PFA) fixed bacteria via amine groups present on the bacterial cell wall. To optimize bacterial labeling, PFA fixed bacteria were first incubated with 0.1 mM up to 0.9 mM concentrations of pHrodo™. A dye concentration of 0.1 mM, yielded the highest ratio between the mean fluorescence intensities of the positive and the negative controls (data not shown) was chosen for further use. To assess whether the fixation or conjugation steps altered the integrity of target antigens, labeled GBS Ia bacteria were compared with live bacteria for reactivity with a pool of mouse sera specific for polysaccharide Ia using flow cytometry analysis. As shown in Fig.

0, although currently, a cluster of biomarkers is recommended for a precise assessment of risk (Simpson and Guy, 2010). A few statistically significant relationships were observed when we calculated univariate correlations between immune parameters and fitness measures; in particular, low levels of U0126 mouse aerobic power were associated with low counts

of CD56dim cells, and individuals with greater muscle force showed higher scores for several T cell activation markers. It is possible that the lack of relationships between aerobic fitness and T-cell subsets could be due to the limited range of fitness levels within our sample (although such a range is typical of the general elderly population). A further potential issue is the phenotyping methods that we used, since

there have been recent reports of an inverse association between aerobic power and ‘senescent/exhausted’ CD8+ T-cells, regardless of age and body mass index, when a four-color Tofacitinib price cytometric flow analysis system is employed (Spielmann et al., 2011). However, when other psychobiological variables (depression, fatigue and quality of life) were introduced into multivariate equations, these latter variables accounted for most of the variance in immune parameters. Proponents of psychoneuroimmunology have long argued the importance of personal well-being to effective immune function (LaPerriere et al., 1994). In part as a consequence of our initial selection, our subjects had relatively normal scores for depression, fatigue and quality of life. Thus, even medroxyprogesterone larger effects might be anticipated across the full spectrum of older individuals. One complication in parceling out effects is that those with clinically significant depression, stressful life events and/or a poor quality of life would

likely show an associated reduction of physical activity (Yosiuchi et al., 2006 and Yoshiuchi et al., 2007). However, the range of fitness levels observed in our sample showed little association with mood state or quality of life, and our observations suggest that immuno-senescence may be countered more effectively by addressing psychological health than by engaging in moderate aerobic or resistance training. We should finally underline that all of our observations were made on circulating blood. Blood concentrations of lymphocytes are probably the most important factor in gauging immune health, although since some 99% of these lymphocytes are located elsewhere in the body, altered cell numbers in the aging could reflect in part a redistribution of cells rather than alterations in absolute cell numbers.

Recent work from Dey et al. showed that miR-21 targets PTEN protein expression and promotes ccRCC survival and invasion through Akt/TORC1 signaling [52]. Taken together, our data provide strong evidence that Hippo signaling plays an important role in regulating proliferation, invasiveness, and metastatic potential of ccRCC and might serve as a target for therapeutic intervention in the future. Disrupted Hippo signaling and consecutive derepression and activation of YAP lead to increased production of the putative YAP target genes EDN1, EDN2, and c-Myc. Increased endothelin signaling in turn results in increased production CDK inhibition of proproliferative and proinvasive mediators by ccRCC cells and

might thus enhance metastatic colonization. Therefore, future studies aimed at developing specific inhibitory drugs of the Hippo signaling pathway or its downstream effectors described here seem warranted to generate novel therapeutic regimens against ccRCC.

“Murine 12/15-lipoxygenase (LOX) and its human homolog 15-LOX have long been known as generators of free acid eicosanoids, primarily 12- and 15-hydroxyeicosatetraenoic acids (HETEs), respectively. More recently, we showed these enzymes directly oxidize intact phospholipid, generating phosphatidylethanolamine (PE)-esterified forms that can dampen Toll-like receptor 4 signaling in human monocytes [1] and [2]. Analogous

lipids are generated by neutrophil 5-LOX and platelet 12-LOX, including MK 2206 phosphatidylcholine (PC) esterified homologs that can stimulate coagulation and regulate leukocyte anti-bacterial actions [3] and [4]. Since HETE-PEs remain cell associated following their generation, we sought to examine whether they could be involved in membrane regulatory processes. Autophagy is the process by which cells remove ageing organelles and damaged cellular structures [5]. There are three defined types of autophagy: macro-, micro-, and chaperone-mediated, all of which promote proteolytic degradation of cytosolic components at the lysosome. Autophagy begins with Idelalisib an isolation membrane, also known as a phagophore that is likely derived from lipid bilayer contributed by the endoplasmic reticulum (ER) and/or the trans-Golgi and endosomes. This expands to engulf intracellular cargo, sequestering it in a double-membraned autophagosome. This matures through lysosome fusion, promoting degradation of autophagosomal contents by lysosomal hydrolases. Lysosomal permeases and transporters export amino acids and other by-products of degradation back out to the cytoplasm, where they are re-used for cellular processes [6]. One particular type of autophagy, mitophagy, which removes old and damaged mitochondria, comprises several different processes termed Types 1–3 [7].

In PD, most biomarker discovery studies have relied on the proteome analysis of CSF. Using 2-DE, CSF profiling allowed the detection of a few differential proteins (i.e., complement c3) between control and PD patients [222] and [223]. Much more changes were detected in the CSF composition of PD patients using shotgun proteomic quantitative strategies as reviewed in [224]. Abdi et al.

found 72 proteins – including ceruloplasmin or apolipoprotein H, uniquely associated to PD compared to AD, dementia with LBs and control Selleck isocitrate dehydrogenase inhibitor patient samples differentially labeled with iTRAQ-4plex [218]. Based on these results, Zhang et al. performed a large-scale validation of their best potential candidates using a Luminex assay and found that a panel of eight proteins (i.e., tau, amyloid β-42, β-2 microglobulin, interleukin- 8, vitamin D binding protein, apolipoproteins A-II and E and BDNF) was highly effective at identifying PD [225]. The find more proteomic analysis of plasma and serum

samples was proved challenging considering their complexity and the presence of a few highly abundant proteins. However, recent studies successfully highlighted potential PD biomarkers in blood [226], [227] and [228], of which the most promising may be plasma apolipoprotein A1 (ApoA1) [227]. This result was confirmed by independent studies based on multiplex and ELISA immunoassays, which suggested that low ApoA1 levels correlated with early PD onset and greater dopaminergic deficit as measured by putaminal DA transporter binding [229]. Alternatively, peripheral blood lymphocytes were investigated, highlighting a panel of five proteins (cofilin, tropomyosin, gamma-fibrinogen, ATP synthase beta and basic actin variant), which may be useful for PD diagnosis [230]. In the future, other sources of potential biomarkers accessible in

vivo may be investigated by proteomics ( Table 1, Table 3). Moreover, as shown on Fig. 1, tissue biomarkers may be found in peripheral regions susceptible to Lewy pathology such as submandibulary gland, colon, or skin [50], [53], [185] and [231]. These regions could be accessed through biopsy PtdIns(3,4)P2 in living patient and could allow the detection of early disease biomarkers, as the peripheral nervous system may be involved before the central nervous system in PD. Saliva was recently analyzed given its connection to the submandibular gland, which produces most of the salivary volume [29]. Importantly, α-SYN and DJ-1 were successfully identified in saliva, providing further relevance for the study of this fluid in a biomarker context [184]. Finally, unbiased proteomics investigations of post-mortem tissues from selected PD-relevant brain regions of neuropathologically confirmed cases might provide useful candidate biomarker proteins, which could further be screened in biofluids using immunoassay or targeted proteomics such as SRM.

We further categorized the inpatient population into those who had VCE placed within 3 days and after 3 days of admission and examined the association between time of placement and detection of active bleeding and active bleeding with angioectasia via t tests

of proportions. We similarly examined the relationship between successful therapeutic intervention and comorbidities and timing of VCE placement. Additionally, we compared timing of VCE placement with length of stay through t tests of means. In all instances, a P < .05 was considered to be statistically significant. Finally, we conducted post-hoc power calculations on key outcomes of interest to assess whether lack of significance was likely Pifithrin �� because of low power or to a truly small effect. All statistical analyses were conducted by using SAS 9.2

software (SAS Institute Inc., Cary, North Carolina, USA), whereas post-hoc power calculations were performed by using Power Analysis and Sample Size (PASS 11.0, NCSS LLC, Kaysville, Utah, USA). Because this was a retrospective study, with data collected from previously recorded data, the study was waived for Navitoclax cost a full review by the Institutional Review Board of the University of Massachusetts Medical Center and received expedited approval. The study design, including distribution of the patients, is showed in Figure 1, and patient demographics are presented in Table 1. A positive result was defined as active bleeding, angioectasia, red spot, tumor, ulcer, or bleeding outside of the small intestine (stomach or colon). The overall yield of VCE was 65.9% (95 of 144) for the inpatient population versus 53.4% (62 of 116) for the outpatient population Guanylate cyclase 2C (P = .054).

Red spots were included in the list of positive findings but were not included in the analysis. Findings of VCE for inpatients are presented in Table 2. The mean hematocrit on admission was 26.8% ± 6%. The inpatient population was further divided into those who had VCE placed within 3 days of admission (n = 90) and those who had VCE placed after 3 days of admission (n = 54) for OOGIB. We were interested in lesions in which endoscopic intervention was potentially feasible. We therefore looked specifically at patients with either active bleeding or angioectasia. Active bleeding was found in 28.9% of the <3-day cohort (26 of 90) compared with 13.0% of the >3-day cohort (7 of 54) (P = .028) ( Fig. 2). The yield to find either an active bleed and/or an angioectasia was 44.4% in the <3-day cohort (40 of 90) versus 27.8% in the >3-day cohort (15 of 54) (P = .046) ( Fig. 2). Two VCEs from each cohort showed evidence of both an active bleed and one or more angioectasia. Detection of active bleeding declined progressively for each day after admission (Fig. 3) as did the detection of active bleeding and angioectasia for each day after admission (Fig. 4) for the inpatient population.

In the series of Yamatogi and Ohtahara, 75% of patients developed

West syndrome between 2 and 6 months of age, and 12% subsequently developed Lennox-Gastaut syndrome [10]. The transition is accompanied by changes in electroencephalographic pattern. The evolution to West syndrome is marked by a transition from suppression burst to hypsarhythmia, and further progression to Lennox-Gastaut syndrome is accompanied by the development of a generalized, slow spike-wave pattern. The close relationship among these three syndromes has led to the theory that they represent age-specific reactions in the brain to similar exogenous influences, and to the proposal that they be classified together as the age-dependent epileptic encephalopathies [2] and [8]. Considerable similarities characterize the clinical presentations of Ohtahara syndrome and early myoclonic encephalopathy. Like Ohtahara buy Epigenetics Compound Library Alectinib datasheet syndrome, early

myoclonic encephalopathy presents during the neonatal period, usually within the first 3 months of age, and sometimes as early as a few hours after birth. The initial presentation typically involves the onset of focal myoclonus, usually of the face or extremities and or of only a small area, such as a finger or eyelid. The jerks are often described as erratic or fragmentary because they can shift from one area of the body to another in an asynchronous, seemingly random pattern. Focal seizures are also very common, and occur in more than 80% of cases [12]. These seizures may be overt, involving deviation of an eye

or tonic posturing, or they may be subtle, sometimes involving only autonomic signs such as facial flushing Loperamide or apnea. Tonic spasms are also frequent, occurring both singly and in clusters. The key electroencephalographic feature in early myoclonic encephalopathy comprises a suppression burst pattern, much like that in Ohtahara syndrome (Fig 1). In the case of early myoclonic encephalopathy, however, this pattern is not continuous, and is often more distinct during sleep. It was reported exclusively during sleep in 33% of cases in one study [12]. The suppression burst pattern in early myoclonic encephalopathy may not be appreciated at disease onset, and follow-up electroencephalograms may be necessary to arrive at the diagnosis [13]. The myoclonic movements themselves are not associated with electrographic changes. The suppression burst pattern can evolve into an atypical pattern of hypsarrhythmia in up to 50% of patients, typically occurring at 3-5 months of age [12]. This change is generally transient, lasting months, with a subsequent return to burst suppression, which can last throughout childhood [14]. The prognosis is generally very poor. Up to half of patients die by 2 years of age [5]. The remainder manifest severe psychomotor impairments, including some patients who remain in a persistent vegetative state [15].

Superoxide radicals are normally produced by the enzyme NADPH oxidase in order to activate APO866 cost the defense mechanisms against invading pathogens (Halliwell and Gutteridge, 2007). Superoxide is produced by the electron transport chain from oxygen occupying the final position and acting as the terminal electron acceptor. Some electrons can randomly “leak” from the electron transport chain (Campian et al., 2004) and interact with oxygen

to produce superoxide radicals. Thus under physiological conditions, about 1–3% of the oxygen molecules in the mitochondria are converted into superoxide radicals. Superoxide radical is normally present mainly in the form of an anion radical and is removed by a dismutation reaction (Liochev and Fridovich, 2000): equation(1) 2O2−·+2H+⟶SODH2O2+O2 While without SOD this reaction AZD4547 clinical trial proceeds very slowly (k ∼ 0.2 M−1 s−1), the reaction becomes biologically relevant

when it is catalyzed by the SOD. The kinetic constant of the SOD-catalyzed superoxide depletion dismutation reaction has been estimated to be 2.5 × 109 M−1 s−1 ( Liochev and Fridovich, 2003). A mutual link between superoxide radicals and iron shows, that under in vivo stress conditions, an excess of superoxide releases “free iron” from iron-containing molecules (e.g. ferritin). The release of iron by superoxide has also been demonstrated for the [4Fe–4S] cluster-containing enzymes. Inactivation of these enzymes by O2− is a rapid process that leads to oxidation of the iron-sulphur cluster. The native clusters contain two Fe(II) and two Fe(III) ions, and the oxidation [one Fe(II) is oxidized to Fe(III)] may be denoted as follows (Liochev and Fridovich, 1994): equation(2) [2Fe(II) 2Fe(III)–4S]2+ + O2−  + 2H+ → [Fe(II) 3Fe(III)–4S]3+ + H2O2 The rate constant for reaction Branched chain aminotransferase (2) has been estimated in the range of 108 to 109 M−1 s−1. Since the oxidized protein binds the Fe(III) more firmly, Fe(II) ions are released from protein

according to the following reaction: equation(3) [Fe(II) 3Fe(III)–4S]3+ → [3Fe(III)–4S]+ + Fe(II) The released Fe(II) can participate in the Fenton reaction, generating highly reactive hydroxyl radicals ( OH) (Prousek, 2007) equation(4) Fe(II) + H2O2 → Fe(III) +  OH + OH−  (Fenton reaction) The Fenton reaction has its in vivo significance mainly under state of an organisms overloaded by iron (as in the conditions of hemochromatosis, b-thalassemia, hemodialysis). Thus high amounts of “free available iron” can have deleterious effects (Kakhlon and Cabantchik, 2002). The superoxide radical participates in the Haber–Weiss reaction (Liochev and Fridovich, 2002): equation(5) O2−  + H2O2 → O2 +  OH + OH−which is a combination of Fenton reaction and the reduction of Fe(III) by superoxide: equation(6) Fe(III) + O2−  → Fe(II) + O2 The hydroxyl radical is highly reactive with a half-life in aqueous solution of less than 1 ns (Pastor et al., 2000).

The mouse scapulae (1 sample at each time point) were contained in sealed sample chambers. These were mounted on a 2-axis motorised linear stage on beamline I22 at the Diamond Light Source (Harwell, Oxfordshire, United Kingdom). A schematic of the setup is shown in Fig. 1(A). A synchrotron X-ray beam (wavelength λ = 1.24 Å, beam cross section 200 μm × 200 μm) was used to measure the SAXS patterns. SAXS patterns were collected on a 2D multiwire RAPID2D detector system [17]. The distance between the sample and the detector was

7.57 m, which was verified with a calibration standard. Each SAXS data frame had a pixel resolution of 512 × 512 pixels and a pixel size of 383.4 × 383.4 μm2. Exposure time for a single SAXS image was 10 s. SAXS patterns of scapulae were collected in a raster map  Fig. 1(C) of 3.4 × 3.4 mm2 with a step size of Selleck Pexidartinib 200 μm in both vertical and horizontal directions. The scanning composite SAXS map ( Fig. 2) of the mouse scapula, which illustrates the distribution of the measurement positions, was obtained by translating the chamber horizontally and vertically.

Selleckchem SRT1720 Two dimensional SAXS images were analysed as described previously by Rinnerthaler et al. [18]. We determined two numerical parameters from each SAXS pattern in this study: the predominant direction of orientation (χ) and the degree of orientation (ρ) of mineral particles; both these parameters reflect the collagen fibril orientation and direction, and thus give an indication of the local nanostructural characteristics PAK6 of the bone tissue. The predominant direction of orientation of mineral particles can be derived using the χ parameter, as the particles are aligned along the main

axis of the collagen fibril [18]. Scattering intensity is plotted as a function of the azimuthal polar angle (χ) ( Fig. 1(D)) for a SAXS pattern in Fig. 1(E). Two peaks are separated by 180° (dark grey curve is the fitted Gaussian curves with centres separated by 180°). χ1 and χ1 + 180 are maximum scattering intensities. The direction of the mineral crystal long axis is defined by the angle χ = χ1 + 90. We compared the χ parameter at the LB (bony ridge; Fig. 3(A) black box) and the IF (flat bone; Fig. 3(A) white box) in the same scapula, to illustrate the impact of different muscle forces on the direction of mineral particle orientation. To ensure comparability, the same anatomical regions were selected in scapulae for all ages, in both wild type and Hpr mice. In order to compare the angle of the mineral crystals between scapulae of different ages, the direction of the LB ( Fig. 3(A–B) black dashed line) of each scapula was used as a reference line. SAXS data from the same two distinct tissue regions in the same scapula (Fig. 3(A–B)) were used to quantify the degree of orientation (ρ) of the mineral crystals, as previously defined by other researchers [18].

Some studies showed that intraperitoneal administration of Tepary bean (Phaseolus acutifolius) crude extract presented toxic effects as weight loss, negative efficiency on protein ratio, negative net protein utilization, poor digestion of proteins and death of rats and mice after 10 days treatment, however, after autoclaving the crude extract, the toxic effects were lost [17]. Studies on the toxicity of semipure lectins from Tepary bean intraperitoneally administrated in CD-1 mice, found a lethal Belinostat clinical trial dose (LD50) of 1100 and 1120 mg/kg body weight for males and females, respectively

[18]. A semipure lectin fraction from Tepary bean seeds (TBLF) obtained by a molecular weight exclusion chromatography protocol exhibits in vitro antiproliferative differential effect on cancer and

normal cells [19]. Before testing the in vivo anticancer effect, we studied the acute toxicity of TBLF using intragastric doses from 5 to 2,000 mg/body weight kg suggesting a AZD5363 secure dose of 50 mg/kg. The intragastric 50 mg/kg TBLF dose was assayed for subchronic toxicity (daily dosing for 28 days) where no toxic or adverse effects were observed, therefore 50 mg/kg TBLF was determined as the NOAEL [20]. Here we present a short-term assay in order to know the digestion resistance of lectins and the effect on complete blood count (CBC) after 24 h of 50 mg/kg TBLF single-dose administration. The anti-nutritional effects and toxic parameters of a 6-week schedule study (intragastric administration every third day) were studied; where food intake, body weight, biochemical blood markers and histopathological analysis were included. Sprague Dawley (SD) rats were purchased from Institute of Neurobiology, Universidad Nacional Autonoma de Mexico (INB-UNAM) and placed in individual cages with ad libitum water and rodent chow food (Rodent Laboratory Chow 5001, Saint Louis, MO, USA). The animals remained one week

for acclimatization where the circadian cycle was adjusted to 12 h light/12 h darkness, at 22° C and a relative humidity of 30%. The animals were sacrificed by decapitation at the end of the experiments. The experimental protocol was PLEK2 based on the Mexican official standard [21] and approved by the INB-UNAM ethics committee. We have performed a standardized method for TBLF obtaining [19]. Some modifications were done in order to improve the lectin enrichment. Briefly, Tepary bean seeds were grinded (A-10 Analytical Tekmar mill) and degreased with chloroform-methanol 2:1 in a 4:1 w/v proportion, stirring for 15 min and then vacuum filter; this process was repeated 2 more times and flour was dried at room temperature in a fume hood.

We quantified these mediators based on our TSA HDAC in vivo knowledge of previous findings showing that AE improves the immunologic response by increasing levels of Th1 cytokines (Ray and Cohn, 2000) or the anti-inflammatory cytokine IL-10 (Nakagome et al., 2005). However, our results have shown that AE did not modify the expression of either Th1 cytokines (IL-2 and IFN-γ) or IL-10. Altogether, our results may suggest that AE acts directly on Th2 cytokine expression; however, the precise mechanism for such an effect needs to be evaluated in the near future. Levels of exhaled nitric oxide (ENO) have been considered to be a marker of

airway inflammation in asthmatic patients and are increased in asthmatic patients (Prieto et al., 2002). Suman and Beck (2002) suggested that the inhibition of NO synthesis slightly attenuates exercise-induced bronchoconstriction. Although we showed that OVA sensitization increased ENO to levels similar to those observed in another OVA-induced asthma model in guinea pigs (Prado et al., 2005), this increase was not reduced by AE, which suggests that the effect of AE was not mediated by NO in our guinea pig model of asthma. Airway remodeling is an important feature

of the asthmatic airway and seems to be a consequence of non-resolved inflammation as well as an imbalance in the healing and repair process (Irvin and Wenzel, 1995). Airway remodeling is characterized by epithelium desquamation, the increased deposition of

extra-cellular matrix proteins on the airway Obeticholic Acid solubility dmso wall and airway smooth muscle hypertrophy and hyperplasia (Larché et al., 2003). In our animal model, OVA exposure induced an increase in airway edema and bronchoconstriction as well as in the epithelium and smooth muscle. Although AE reduced airway edema, AE had no effect on airway smooth muscle or on bronchoconstriction. One limitation of our study is that we did not evaluate central (cartilaginous) airways that play an important role in the pulmonary mechanical changes secondary to antigen challenge in asthmatic patients and murine animal Glutamate dehydrogenase model of asthma. It is possible that the absence of reduction on airway smooth muscle and bronchoconstriction induced by exercise training may be due the fact that we have evaluated only peripheral and not central airways. In contrast, aerobic training induced a thickening of the airway epithelium. The effect on the airway epithelium observed in our study was previously reported by Chimenti et al. (2007), who demonstrated that aerobic training increases apoptosis and the proliferation rate of the airway epithelium independent of any previous inflammation. Our results have also shown that AE did not reduce OVA-induced airway remodeling in our guinea pig model of asthma, contrary to other mouse studies from our group and others demonstrating the beneficial effects of AE on airway remodeling (Pastva et al., 2004, Vieira et al., 2007 and Silva et al., 2010).
