Viral Stimuli Trigger Exaggerated Thymic Stromal Lymphopoietin Expression by Chronic Obstructive Pulmonary Disease Epithelium: Role of Endosomal TLR3 and Cytosolic RIG-I-Like Helicases.

Background: Rhinovirus (RV)-induced chronic obstructive pulmonary disease (COPD) exacerbations exhibit TH(2)-like inflammation. We hypothesized that RV-infected bronchial epithelial cells (BEC) overproduce TH(2)-switching hub cytokine, thymic stromal lymphopoietin (TSLP) in COPD. Methods: Primary BEC from healthy (HBEC) and from COPD donors (COPD-BEC) were grown in 12-well plates, infected with RV

Evaluation of quantitative (90)Y SPECT based on experimental phantom studies.

In SPECT imaging of pure beta emitters, such as (90)Y, the acquired spectrum is very complex, which increases the demands on the imaging protocol and the reconstruction. In this work, we have evaluated the quantitative accuracy of bremsstrahlung SPECT with focus on the reconstruction algorithm including model-based attenuation, scatter and collimator-detector response (CDR) compensations. The scat

Development of an automated method for display of ischemic myocardium from simulated electrocardiograms.

BACKGROUND: Knowledge of the size and location of ischemic myocardium during acute coronary occlusion could provide decision support before reperfusion therapy. Electrocardiogram (ECG) scores based on the number of leads and the sum of ST-segment elevation have been unreliable in quantifying ischemia. We aimed to develop a new method to graphically display ischemic myocardium from simulated ECGs (

Effect of an Occupation-Focused Family Intervention on Change in Parents' Time Use and Children's Body Mass Index.

OBJECTIVE. This study explored factors related to changes in the time parents spent with their children with obesity and associated decreases in children's body mass index (BMI) z-scores after an occupation-focused intervention. METHOD. Parents participated in a 1-yr occupation-focused intervention to promote healthy family lifestyles. Data on 40 parents of 22 children with obesity ages 4-6 yr wer

Tree-ring stable carbon isotope-based May-July temperature reconstruction over Nanwutai, China, for the past century and its record of 20th century warming

Growth anomaly of trees in some regions was detected under current episode of rapid warming. Thisraises a dilemma for temperature reconstructions by using tree-ring width which is believed to be themost important proxy on inter-annual temperature reconstruction during the past millenniums. Here weemployed the tree-ring d13C to reconstruct temperature variations for exploring their potential oncapt

The Wnt-5a-derived hexapeptide Foxy-5 inhibits breast cancer metastasis in vivo by targeting cell motility.

PURPOSE: An inherent problem in breast cancer treatment is that current therapeutic approaches fail to specifically target the dissemination of breast cancer cells from the primary tumor. Clinical findings show that the loss of Wnt-5a protein expression in the primary breast tumor predicts a faster tumor spread, and in vitro analyses reveal that it does so by inhibiting tumor cell migration. There

Obesity in orthopedic patients.

BACKGROUND: To investigate the correlation between various orthopedic conditions and overweight/obesity at the Department of Orthopedics, Malmö University Hospital Sweden. Obesity is associated with numerous major medical conditions. Although the relationship between gonarthrosis and osteoarthritis and body mass index (BMI) is well recognized, other orthopedic conditions have been less well studie

Effects of prothrombin on the individual activated protein C-mediated cleavages of coagulation factor Va.

The factor Va (FVa) inactivation by activated protein C (APC), mediated by cleavages at Arg306 and Arg506 in FVa, is inhibited by both factor Xa (FXa) and prothrombin. While FXa is known to specifically inhibit the Arg506 cleavage, the effect of prothrombin has not been confined to one cleavage site. We used recombinant FV variants, FV:506Q/679Q and FV:306Q/679Q, to investigate the effect of proth

Confirmation of the Intracoronary Near-Infrared Spectroscopy Threshold of Lipid-Rich Plaques That Underlie ST-Segment-Elevation Myocardial Infarction.

In a previous exploratory analysis, intracoronary near-infrared spectroscopy (NIRS) found the majority of culprit lesions in ST-segment-elevation myocardial infarction (STEMI) to contain a maximum lipid core burden index in 4 mm (maxLCBI4mm) of >400. This initial study was limited by a small sample size, enrollment at a single center, and post hoc selection of the maxLCBI4mm ≥400 threshold. This s

Constructions of work stress and coping in a female- and a male-dominated department.

In the present study the nature of stress and coping was investigated and considered as socially constructed. Thirty small group interviews were performed using the Critical Incident Technique in one female- and one male-dominated customer service department of a telecom company. The main themes about stress among both women and men were often expressed as collective phenomena and were connected t

Tumor selectivity at short times following systemic administration of a liposomal temoporfin formulation in a murine tumor model

Meso-tetra(hydroxyphenyl)chlorin (mTHPC) (INN: Temoporfin) is one of the most potent photodynamically active substances in clinical use. Treatment protocols for Temoporfin-mediated photodynamic therapy often rely on drug-light intervals of several days in order for the photosensitizer to accumulate within the target tissue, though tumor selectivity is limited. Here, the mTHPC localization was stud

On the efficiency and gain of antennas

The fundamental limits of the gain and e±ciency of an antenna are explored. These are very important quantities for, e.g., superdirective arrays. The antenna is in this paper con¯ned in a sphere and all of the currents are assumed to run in a material with a given conductivity. It is shown that one can ¯nd the current distribution in the sphere that optimizes the gain, given the frequency and the

Challenges in prosthesis classification.

Accurate prosthesis classification is critical for total joint arthroplasty surveillance and assessment of comparative effectiveness. Historically, prosthesis classification was based solely on the names of the prosthesis manufacturers. As a result, prosthesis designs changed without corresponding name changes, and other prostheses' names changed over time without substantial design modifications.

V-ATPase-mediated phagosomal acidification is impaired by Streptococcus pyogenes through Mga-regulated surface proteins.

Streptococcus pyogenes, a significant bacterial pathogen in humans, interferes with the membrane traffic of human neutrophils and survives following phagocytosis. The mechanism(s) behind this property is not known, but in contrast to wild-type bacteria, mutant bacteria lacking virulence factors regulated by the transcriptional regulator Mga, are phagocytosed and killed. In the present work we inve

A compact planar MIMO antenna system of four elements with similar radiation characteristics and isolation structure

A compact planar multiple-input-multiple-output (MIMO) antenna system of four elements with similar radiation characteristics is proposed for the whole 2.4-GHz WLAN band. It consists of two proximity-coupled fed microstrip square ring patch antennas and two lambda/4 microstrip slot antennas of the same linear polarization. These two types of antennas are printed on different sides of the substrate
