Increased percentage of IFN-γ producing CD56CD3 cells in active tuberculosis patients upon CFP-10 stimulation of peripheral mononuclear cells
Aiming to identify a possible biomarker that distinguishes immune cellular response of active tuberculosis from latent infection. Peripheral blood mononuclear cells (PBMCs) of pulmonary tuberculosis patients (PTB), tuberculin positive household contacts (TST+ HHC), and tuberculin negative non-household contacts (TST− Non HHC) were stimulated with PPD or CFP-10 and the percentage of CD69+ cells, proliferating precursor and IFN-γ producing CD4+, CD8+, CD56+CD3− and CD56+CD3+ cells were compared. IL-2, IL-12p70, IL-15, IL-18 and IL-10 were measured in culture supernatants. (Source: Tuberculosis)

Protein and microRNA biomarkers from lavage, urine, and serum in military personnel evaluated for dyspnea
Conclusions: Candidate proteins and miRNAs associated with the general diagnosis of dyspnea have been identified in subjects with differing medical diagnoses. Since these markers can be measured in readily obtained clinical samples, further studies are possible that test the value of these findings in more formal classification or case-control studies in much larger cohorts of subjects with specific lung diseases such as asthma, emphysema, or some other well-defined lung disease.

Anticholinergics/Antimuscarinic Drugs in Asthma
Abstract Anticholinergic alkaloids have been used for thousands of years for the relief of bronchoconstriction and other respiratory symptoms, and their use in the treatment of chronic obstructive pulmonary disease is well established. Acetylcholine, acting through muscarinic receptor (M) receptor, modulates multiple physiologic functions pertinent to asthma including airway muscle tone, mucus gland secretion, and various parameters of inflammation and remodeling. In addition, activation of M receptors may inhibit beta2 adrenoreceptor. These observations offer the rationale for the use of M receptors antagonists ...

Intestinal current measurement versus nasal potential difference measurements for diagnosis of cystic fibrosis: a case-control study
Background: Nasal potential difference (NPD) and intestinal current measurement (ICM) are functional CFTR tests that are used as adjunctive diagnostic tools for cystic fibrosis (CF). Smoking has a systemic negative impact on CFTR function. A diagnostic comparison between NPD and ICM and the impact of smoking on both CFTR tests has not been done. Methods: The sweat chloride test, NPD, and ICM were performed in 18 patients with CF (sweat chloride >60 mmol/l), including 6 pancreatic sufficient (PS) patients, and 13 healthy controls, including 8 smokers. The NPD CFTR response to Cl-free and isoproterenol perfusion (Delta0Cl- +...

Systematic identification of transcriptional and post-transcriptional regulations in human respiratory epithelial cells during influenza A virus infection
Conclusion: Compared with other representative state-of-the-art algorithms, the proposed SITPR framework can more effectively identify the activated transcriptional and post-transcriptional regulations simultaneously from a given background network. The idea of SITPR is generally applicable to the analysis of gene regulatory networks in human cells. The results obtained for human respiratory epithelial cells suggest the importance of the transcriptional, post-transcriptional regulations as well as their synergies in the innate immune responses against IAV infection.

A chalcone with potent inhibiting activity against biofilm formation by nontypeable Haemophilus influenzae
In this study, a series of natural and synthetic chalcones with various chemical substituents were evaluated in vitro for their antibiofilm activities against strong biofilm‐forming strains of NTHi. Of the test chalcones, 3‐hydroxychalcone (chalcone 8) exhibited the most potent inhibitory activity, its mean minimum biofilm inhibitory concentration (MBIC50) being 16 μg/mL (71.35 μM), or approximately sixfold more active than the reference drug, azithromycin (MBIC50 419.68 μM). The inhibitory activity of chalcone 8, which is a chemically modified chalcone, appeared to be superior to those of the natural chalcone...

Duration of Gestation and Mode of Delivery Affect the Genes of Transepithelial Sodium Transport in Pulmonary Adaptation.
Conclusions: In late preterm and early term infants, low expression of ENaC and SGK1 may parallel insufficient lung liquid clearance predisposing to respiratory distress. Lower SGK1 expression after term CD could translate into insufficient sodium and lung liquid absorption. The findings demonstrate a central role for cortisol in regulation of ENaC and potentially perinatal sodium and lung liquid clearance. © 2014 S. Karger AG, Basel.

A randomized controlled trial of capnography during sedation in a pediatric emergency setting
Data suggest that capnography is a more sensitive measure of ventilation than standard modalities and detects respiratory depression before hypoxemia occurs. We sought to determine if adding capnography to standard monitoring during sedation of children increased the frequency of interventions for hypoventilation, and whether these interventions would decrease the frequency of oxygen desaturations.

Snoring – Obnoxious (but medically innocent) noise or wakeup call for sleep medicine?
In the present issue of Sleep Medicine Reviews, there are two articles with complementary reviews of adult and pediatric snoring [1,2]. Both studies acknowledge that snoring is often a marker of obstructive sleep apnea, but they also highlight the greater frequency of this symptom and its potential independent clinical importance. The most important issue raised by both reviews is the persisting question about the significance of snoring in the absence of frank obstructive sleep apnea. Both reviews allude to the assumption that snoring is the mildest form of the obstruction we loosely call “sleep disordered breathing” ...

Bioenergetic differences between MCF-7 and T47D breast cancer cells and their regulation by estradiol and tamoxifen
Estrogen receptor α (ERα+) breast tumors rely on mitochondria (mt) to generate ATP. The goal of this study was to determine how estradiol (E2) and 4-hydroxytamoxifen (4-OHT) affect cellular bioenergetic function in MCF-7 and T47D ERα+ breast cancer cells in serum-replete versus dextran-coated charcoal (DCC)-stripped fetal bovine serum (FBS)-containing medium (‘serum-starved’). Serum-starvation reduced oxygen consumption rate (OCR), extracellular acidification rate (ECAR), ATP-linked OCR, and maximum mt capacity, reflecting lower ATP demand and mt respiration.

The Anatomy of the Dog Soft Palate. III. Histological Evaluation of the Caudal Soft Palate in Brachycephalic Neonates
ABSTRACT A thickened and abnormally long soft palate is mostly involved in the pathogenesis of both nasopharyngeal and oropharyngeal narrowing, affecting the respiratory activity in virtually all of the brachycephalic dogs suffering from Brachycephalic Airway Obstructive Syndrome (BAOS). The morphology of the soft palate in adult mesaticephalic and brachycephalic dogs has been previously described. In this article specimens from brachycephalic dog neonates (N = 10) dead from one to 3 hr after birth of unrelated conditions were collected and histologically evaluated at three transverse levels to describe the microscopic...

Thromboxane-Induced Actin Polymerization in Hypoxic Neonatal Pulmonary Arterial Myocytes Involves Cdc42 Signaling.
Abstract In hypoxic pulmonary arterial (PA) myocytes, challenge with thromboxane mimetic U46619 induces marked actin polymerization and contraction, phenotypic features of persistent pulmonary hypertension of the newborn (PPHN). Rho GTPases regulate the actin cytoskeleton. We previously reported U46619-induced actin polymerization in hypoxic PA myocytes occurs independently of the RhoA pathway, and hypothesized involvement of the Cdc42 pathway. PA myocytes grown in normoxia or hypoxia for 72 hrs were stimulated with U46619, then analyzed for Rac/Cdc42 activation by affinity precipitation, PI3K activity by phospho-A...

Animal models of bronchopulmonary dysplasia. V: The preterm baboon models.
Abstract Much of the progress in improved neonatal care, particularly management of under-developed preterm lungs, has been aided by investigations of multiple animal models, including the neonatal baboon (Papio species). In this chapter we highlight how the preterm baboon model at both140d and 125 d gestation (term equivalent 185d) has advanced our understanding and management of the immature human infant with neonatal lung disease. Not only is the 125-d baboon model extremely relevant to the condition of BPD but there are also critical neurodevelopmental and other end-organ pathological features associated with t...

Carl Wilhelm Scheele, the discoverer of oxygen, and a very productive chemist.
Abstract Carl Wilhelm Scheele (1742-1786) has an important place in the history of the discovery of respiratory gases because he was undoubtedly the first person to prepare oxygen and describe some of its properties. In spite of this, his contributions have often been overshadowed by those of Joseph Priestley and Antoine Lavoisier who also played critical roles in preparing the gas and understanding its nature. Sadly, Scheele was slow to publish his discovery and therefore Priestley is rightly recognized as the first person to report the preparation of oxygen. Having said this, the thinking of both Scheele and Prie...

TRPV4: an exciting new target to promote alveolo-capillary barrier function.
Abstract Transient receptor potential (TRP) channels are emerging as important players and drug targets in respiratory disease. Amongst the vanilloid-type TRP channels (which includes the six member of the TRPV family), target diseases include cough, asthma, cancer, and more recently, pulmonary edema associated with acute respiratory distress syndrome. Here, we critically evaluate a recent report that addresses TRPV4 as a candidate target for the management of acute lung injury that develops as a consequence of aspiration of gastric contents, or acute chlorine gas exposure.

Sleep-disordered breathing, type 2 diabetes and the metabolic syndrome.
Abstract Sleep-disordered breathing (SDB) encompasses a spectrum of conditions that can lead to altered sleep homeostasis. In particular, obstructive sleep apnoea (OSA) is the most common form of SDB and is associated with adverse cardiometabolic manifestations including hypertension, metabolic syndrome and type 2 diabetes, ultimately increasing the risk of cardiovascular disease. The pathophysiological basis of these associations may relate to repeated intermittent hypoxia and fragmented sleep episodes that characterize OSA which drive further mechanisms with adverse metabolic and cardiovascular consequences.

Abstract Here we present a detailed statistical analysis of the discharge characteristics of mitral cells of the main olfactory bulb of urethane‐anesthetized rats. Neurons were recorded from the mitral cell layer, and antidromically identified by stimuli applied to the lateral olfactory tract. All mitral cells displayed repeated, prolonged bursts of action potentials typically lasting >100 sec and separated by similarly long intervals; about half were completely silent between bursts. No such bursting was observed in nonmitral cells recorded in close proximity to mitral cells. Bursts were asynchronous among even adja...
