Should We Let Sleeping Dogs Lie? Controversies of Treating Central Sleep Apnoea in HFrEF Following the SERVE-HF Study
Central sleep apnoea (CSA) is characterised by cycles of apnoea, hypopnoea and hyperpnoea during sleep due to abnormalities in the regulation of breathing within the respiratory centre in the brainstem. CSA, defined as an apnoea –hypopnoea index (AHI) of ≥15 events/h, is common in patients with heart failure (HF), with a prevalence of 20–45 %.1, 2 Its presence is reported to be a marker of severity of HF. It is also described in some studies to be independently associated with increased morbidity and mortality rates in patients with HF.3 (Source: Radcliffe Cardiology)

Complete genomic sequence and comparative analysis of four genital and respiratory isolates of bovine herpesvirus subtype 1.2b (BoHV-1.2b), including the prototype virus strain K22
We report here the complete genomic sequence of four BoHV-1.2b isolates. The DNA sequence identity of the four genomes is 98.9 %. Differences were primarily in regions containing direct repeats, specifically gene UL36 and the terminal repeat regions immediately flanking gene BICP22. BoHV-1.2b and BoHV-1.1 genomes are similar in size (~135 kb), completely orthologous with respect to regional structure and gene location, a nd have a 97.5 % DNA sequence homology. The most notable difference is the structure of the DNA replication origin of the two viruses. (Source: Archives of Virology)

Pre-Frailty, frailty, and multimorbidity: Prevalences and associated characteristics from two French national surveys
ConclusionOur study highlights that in France, among individuals older than 55 years-old and free of disability, around 25% are either frail or multimorbid; another 30% to 40% being pre-frail. Pre-frailty, frailty and multimorbidity are known to be associated with adverse health outcomes and important economic costs. The health system must adapt to respond to the needs of its aging population. In addition, given the efficient impact of prevention actions, our findings emphasize the need to implement prevention strategies against Frailty and multimorbidity in France.

Evaluating targeted interventions via meta-population models with multi-level mixing.
Abstract Among the several means by which heterogeneity can be modeled, Levins' (1969) meta-population approach preserves the most analytical tractability, a virtue to the extent that generality is desirable. When model populations are stratified, contacts among their respective sub-populations must be described. Using a simple meta-population model, Feng et al. (2015) showed that mixing among sub-populations, as well as heterogeneity in characteristics affecting sub-population reproduction numbers, must be considered when evaluating public health interventions to prevent or control infectious disease outbreaks.

Correction of Lung Inflammation in a F508del CFTR murine Cystic Fibrosis model by the Sphingosine-1-Phosphate Lyase Inhibitor LX2931.
Abstract Progressive lung disease with early onset is the main cause of mortality and morbidity in Cystic Fibrosis patients. Here we report a reduction of Sphingosine-1-Phosphate (S1P) in the lung of unchallenged Cftrtm1EUR F508del CFTR mutant mice. This correlates with enhanced infiltration by inducible nitric oxide synthase (iNOS) expressing granulocytes, B- and T-cells. Furthermore, the ratio of macrophage derived dendritic cells (MoDC) to conventional dendritic cells (cDC) is higher in mutant mouse lung, consistent with unprovoked inflammation. Oral application of a S1P-lyase inhibitor (LX2931), increases S1P ...

Cap-independent translation by DAP5 controls cell fate decisions in human embryonic stem cells [Research Papers]
This study unveils an additional level of gene expression regulation involving noncanonical, cap-independent translation of a select group of mRNAs. This is driven by death-associated protein 5 (DAP5/eIF4G2/NAT1), a translation initiation factor mediating IRES-dependent translation. We found that the DAP5 knockdown from human ESCs (hESCs) resulted in persistence of pluripotent gene expression, delayed induction of differentiation-associated genes in different cell lineages, and defective embryoid body formation. The latter involved improper cellular organization, lack of cavitation, and enhanced mislocalized apoptosis. RNA...

Context COPD is, according to the Global Initiative for Chronic Obstructive Lung Disease, defined as persistent airflow limitation, that is, the key diagnostic criterion is a postbronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) ratio <0.70.1 However, this definition has clear limitations in clinical practice, as it does not take symptoms into account and only applies to individuals in whom fixed airflow limit...

Integrated Cardio-Respiratory Control: Insight in Diabetes
AbstractAutonomic dysfunction is a frequent and relevant complication of diabetes mellitus, as it is associated with increased morbidity and mortality. In addition, it is today considered as predictive of the most severe diabetic complications, like nephropathy and retinopathy. The classical methods of screening are the cardiovascular reflex tests and were originally interpreted as evidence of nerve damage. A more modern approach, based on the integrated control of cardiovascular and respiratory function, reveals that these abnormalities are to a great extent functional, at least in the early stage of the disease, thus sug...

Development and Dynamic Regulation of Mitochondrial Network in Human Midbrain Dopaminergic Neurons Differentiated from iPSCs
Publication date: Available online 22 September 2016 Source:Stem Cell Reports Author(s): Du Fang, Yu Qing, Shijun Yan, Doris Chen, Shirley ShiDu Yan Mitochondria are critical to neurogenesis, but the mechanisms of mitochondria in neurogenesis have not been well explored. We fully characterized mitochondrial alterations and function in relation to the development of human induced pluripotent stem cell (hiPSC)-derived dopaminergic (DA) neurons. Following directed differentiation of hiPSCs to DA neurons, mitochondria in these neurons exhibit pronounced changes during differentiation, including mature neurophysiology charact...

Development of vaccines against pertussis caused by Bordetella holmesii using a mouse intranasal challenge model
We examined the protective potency of pertussis vaccines available in Japan and vaccines prepared from B. holmesii. A murine model of respiratory infection was exploited to evaluate protective potency. No Japanese commercial pertussis vaccines were effective against B. holmesii. In contrast, a wBH vaccine and an aBH vaccine prepared from B. holmesii were both protective. Passive immunization with sera from mice immunized with aBH vaccine established protection against B. holmesii, indicating that B. holmesii‐specific serum antibodies might play an important role in protection. Immuno‐proteomic analysis with sera from m...
