Children's exposure to second hand smoke at home: A cross-sectional study in Portugal
This study describes Portuguese children's exposure to SHS at home (total and by Portuguese main regions). In 2010/2011, a questionnaire was applied to a sample of Portuguese children in the 4th grade (N =3187, mean age 9.05±0.7 years, 51.1% male). Descriptive analysis, chi-square tests and crude odds ratios were performed. Of the participants, 62.9% of those with smoking parents and 19.2% of those with non-smoking parents were exposed to SHS at their home. Parental smoking varied significantly among regions and was significantly associated with children's exposure to SHS at home. Children's exposure to SHS at home was hi...

The effects of sex and neonatal stress on pituitary adenylate cyclase‐activating peptide expression
New Findings What is the central question of this study? Does sex or neonatal stress affect the expression of pituitary adenylate cyclase‐activating peptide or its receptors? What is the main finding and its importance? Neonatal–maternal separation stress has little long‐lasting effect on the expression of pituitary adenylate cyclase‐activating peptide or its receptors, but sex differences exist in these genes between males and females at baseline. Sex differences in classic stress hormones have been studied in depth, but pituitary adenylate cyclase‐activating peptide (PACAP), recently identified as playing a c...

Influence of Different Interfaces on Synchrony During Pressure Support Ventilation in a Pediatric Setting: A Bench Study.
CONCLUSIONS: The choice of the interface can influence patient-ventilator synchrony in a pediatric model breathing at increased f, thus making it more difficult to set the ventilator, particularly during noninvasive ventilation. The helmet demonstrated the worst interaction, suggesting that the face mask should be considered as the first choice for delivering noninvasive ventilation in a pediatric model.

Ultrastructural analysis of five patients with total sperm immotility.
In conclusion, we present three cases with DFS associated with total sperm immotility, abnormal mitochondria, and absence of the annulus, central pair complex and radial spokes, of which one had in addition absence of dynein arms and nexin bridges. We also describe a patient, with total sperm immotility and a different presentation of DFS, as the annulus was present and the dysplastic fibrous sheath was restricted to the principal piece. These findings thus confirm the heterogeneity of the DFS condition. The changes observed in the patient with situs-inversus also further support previous observations. PMID: 25601002 [...

Photoinduction of cyclosis-mediated interactions between distant chloroplasts.
Abstract Communications between chloroplasts and other organelles based on the exchange of metabolites, including redox active substances, are recognized as a part of intracellular regulation, chlororespiration, and defense against oxidative stress. Similar communications may operate between spatially distant chloroplasts in large cells where photosynthetic and respiratory activities are distributed unevenly under fluctuating patterned illumination. Microfluorometry of chlorophyll fluorescence in vivo in internodal cells of the alga Chara corallina revealed that a 30-s pulse of localized light induces a transient i...

Stigmatellin Probes the Electrostatic Potential in the QB Site of the Photosynthetic Reaction Center.
Abstract The electrostatic potential in the secondary quinone (QB) binding site of the reaction center (RC) of the photosynthetic bacterium Rhodobacter sphaeroides determines the rate and free energy change (driving force) of electron transfer to QB. It is controlled by the ionization states of residues in a strongly interacting cluster around the QB site. Reduction of the QB induces change of the ionization states of residues and binding of protons from the bulk. Stigmatellin, an inhibitor of the mitochondrial and photosynthetic respiratory chain, has been proven to be a unique voltage probe of the QB binding pock...

Programming and Regulation of Metabolic Homeostasis.
Abstract ABSTRACT Evidence is presented that the rate and equilibrium constants in mitochondrial oxidative phosphorylation set and maintain metabolic homeostasis in eukaryotic cells. These internal constants determine the energy state ([ATP]/[ADP][Pi]), and the energy state maintains homeostasis through a bidirectional sensory/signaling control network that reaches every aspect of cellular metabolism. The energy state is maintained with high precision (to about 1 part in 10(10)) and the control system can respond to transient changes in energy demand (ATP utilization) of more than 100 times the resting rate.

[Newsdesk] Research brief
A study provides evidence for an interaction between respiratory syncitial virus (RSV) and Streptococcus pneumonia infections. An analysis of data collected between 1992 and 2009 on hospital admissions for RSV and for pneumococcal pneumonia among US children younger than 2 years shows that the two diseases shared a distinctive spatiotemporal pattern over the study period. Moreover, among children younger than 1 year, 20% of pneumococcal cases were associated with RSV activity and hospital admissions for RSV declined after the introduction of PCV7 vaccination against S pneumoniae.

Dynamic arterial elastance predicts mean arterial pressure decrease associated with decreasing norepinephrine dosage in septic shock
IntroductionGradual reduction of the dosage of norepinephrine (NE) in patients with septic shock is usually left to the physician?s discretion. No haemodynamic indicator predictive of the possibility of decreasing the NE dosage is currently available at the bedside. The respiratory pulse pressure variation / respiratory stroke volume variation (dynamic arterial elastance (Eadyn)) ratio has been proposed as an indicator of vascular tone. The purpose of this study was to determine whether Eadyn can be used to predict the decrease in arterial pressure when decreasing the NE dosage in resuscitated septic patients. Methods: A p...

Antibodies against the majority subunit of Type IV pili disperse nontypeable Haemophilus influenzae biofilms in a LuxS‐dependent manner and confer therapeutic resolution of experimental otitis media
Summary Despite resulting in a similar overall outcome, unlike antibodies directed against the DNABII protein, integration host factor (IHF), which induce catastrophic structural collapse of biofilms formed by nontypeable Haemophilus influenzae (NTHI), those directed against a recombinant soluble form of PilA [the majority subunit of Type IV pili (Tfp) produced by NTHI], mediated gradual ‘top‐down’ dispersal of NTHI from biofilms. This dispersal occurred via a mechanism that was dependent upon expression of both PilA (and by inference, Tfp) and production of AI‐2 quorum signaling molecules by LuxS. The addition of ...
