PURPOSE OF REVIEW: Whole lung tissue engineering is a relatively new area of investigation. In a short time, however, the field has advanced quickly beyond proof of concept studies in rodents and now stands on the cusp of wide-spread scale up to large animal studies. Therefore, this technology is ever closer to being directly clinically relevant. RECENT FINDINGS: The main themes in the literature include refinement of the fundamental components of whole lung engineering and increasing effort to direct induced pluripotent stem cells and lung progenitor cells toward use in lung regeneration...

Selenium (Se) is vital for health because of its antioxidative and anti-inflammation functions. The aim of this study was to determine if dietary selenium could inhibit the rat lung injury induced by ambient fine particulate matter (PM2.5). Sprague-Dawley rats were randomly allocated in seven groups (n = 8). The rats in PM2.5 exposure group were intratracheally instilled with 40 mg/kg of body weight (b.w.) of PM2.5 suspension. The rats in Se prevention groups were pretreated with 17.5, 35, or 70 μg/kg b...

PURPOSE: Pulmonary hypertension and exercise-induced oxygen desaturation (EID) influence acute exacerbation of COPD. Computed tomography (CT)-detected pulmonary artery (PA) enlargement is independently associated with acute COPD exacerbations. Associations between PA to aorta (PA:A) ratio and EID in patients with COPD have not been reported. We hypothesized that the PA:A ratio correlated with EID and that results of the 6-minute walk test (6MWT) would be useful for predicting the risk associated with PA:A >1...

A highly invasive Du145-III subline was isolated by three successive passages of the parental Du145 prostate tumor cell line (Du145-P) through a Boyden chamber with matrigel-coated membrane support. Du145-III cells showed great invasion potential based on their increased ability to spread/migrate and enhanced expression/secretion of the matrix metalloproteinase 9 (MMP9). Du145-III cells exerted vasculogenic mimicry (VM) properties, reminiscent of endothelial cell characteristics and expressed elevated levels of cancer stem cell (CSC) markers, including Nanog, Sox2, CD44 and ABCG2 and ability to self-renew...

BACKGROUND: Comparability of multiple breath washout (MBW) systems has been little explored. We assessed agreement in lung clearance index (LCI) from two similar, commercial nitrogen MBW setups in patients with Cystic Fibrosis (CF) and controls. METHODS: The EasyOne Pro (NDD) and Exhalyzer D (EM) were randomly applied in 85 adults (34 with CF) and 97 children (47 with CF and normal forced expiratory volume in one second). We assessed differences between setups in LCI, lung volumes and breathing pattern and diagnostic performance for detecting abnormal lung function...

BACKGROUND: Malnutrition is common among congenital diaphragmatic hernia (CDH) survivors and may result from elevated respiratory effort. We evaluated body mass index (BMI), measured resting energy expenditure (mREE) and pulmonary function test (PFT) results in children and adolescents with CDH to determine if there is a correlation. METHODS: With ethics approval (REB# 1000035323), anthropometrics, indirect calorimetry (IC) results and PFTs were collected from patients 5-17years of age during CDH clinic visits between 2000 and 2016...

AIMS: Patients with advanced cancer have been shown to suffer from abnormal cardiac function and impaired exercise capacity that may contribute to their impaired quality of life. As tachycardia is considered as a sign of potential early cardiac damage, we sought to determine whether resting heart rate and other ECG-derived variables have prognostic value. METHODS AND RESULTS: From 2005 to 2010, we enrolled 145 patients with histologically confirmed cancer (36 colorectal, 72 pancreatic, and 37 non-small cell lung cancer patients) and 59 healthy controls...

Lung cancer is the main reason of cancer death worldwide. About 30% of non-small-cell lung cancer (NSCLC) cases are diagnosed with locally advanced disease (stage III). This is a mixed population including patients who have far more extensive and bulky disease than others. Management of these patients continue to be a challenge; frequently, patients have both local recurrence and distant metastases in this stage and the prognosis is very poor with a 5-year overall survival estimated between 3% and 7% for inoperable disease...

We investigated the expression levels of virulence factors (ompA, omp33-36, and carO) in 5 clinical isolates and in a standard ATCC19606 strain of Acinetobacter baumannii to determine their effect on the virulence characteristics of the isolates. The mRNA levels of ompA in the clinical isolates were higher and similar compared with those in ATCC19606, whereas the mRNA levels of omp33-36 in the clinical isolates were lower and similar compared with those in ATCC19606. The mRNA levels of carO in the clinical isolates were significantly higher than those in ATCC19606...

We measured esophageal pressures (n = 4), respiratory flow rates (n = 5), and expired O2 and CO2 (n = 4) in five adult Patagonia sea lions (Otaria flavescens, body mass range 94.3-286.0 kg) during voluntary breaths while laying down out of water. The data were used to estimate the dynamic specific lung compliance (sCL), the O2 consumption rate ([Formula: see text]O2) and CO2 production rates ([Formula: see text]CO2) during rest. Our results indicate that the resting tidal volume in Patagonia sea lions is approximately 47-73% of the estimated total lung capacity...

BACKGROUND: -During adult life, blood vessel formation is thought to occur via angiogenic processes involving branching from existing vessels. An alternate proposal suggests that neo-vessels form from endothelial progenitors able to assemble the intimal layers. We here aimed to define vessel-resident endothelial progenitors in vivo in a variety of tissues in physiological and pathological situations such as normal aorta, lungs, as well as wound healing, tumors and placenta. METHODS: -Based on protein expression levels of common endothelial markers using flow cytometry, three sub-populations of endothelial cells could be identified among VE-Cadherin+ and CD45- cells...

The persistent public health threat of infection with the Middle East respiratory syndrome coronavirus (MERS-CoV) highlights the need for an effective MERS-CoV vaccine. Previous studies have focused mainly on the receptor-binding domain (RBD) on the spike protein of MERS-CoV. Herein, we investigated the immunogenicity and protective potential of the recombinant N-terminal domain (rNTD) of spike proteins as a vaccine candidate. BALB/c mice vaccinated with 5 or 10μg of rNTD protein demonstrated a significant humoral immune response (serum IgG and neutralizing activity)...
