Endophytic bacteria are critical for plant growth and health. However, compositional and functional responses of bacterial endophyte communities towards agricultural practices are still poorly understood. Hence, we analyzed the influence of fertilizer application and mowing frequency on bacterial endophytes in three agriculturally important grass species. For this purpose, we examined bacterial endophytic communities in aerial plant parts of Dactylis glomerata L., Festuca rubra L., and Lolium perenne L. by pyrotag sequencing of bacterial 16S rRNA genes over two consecutive years...

Insight in the molecular structure of humic acid (HA) and fulvic acid (FA) can contribute to identify relationships between their molecular properties, and further our quantitative abilities to model important organic matter functions such as metal complexation and association with mineral surfaces. Pyrolysis gas chromatography/mass spectrometry (Py-GC-MS) is used to compare the molecular composition of HA and FA. A systematic comparison was obtained by using samples from different environmental sources, including solid and aqueous samples from both natural and waste sources...

BACKGROUND: Breastfeeding has been shown to result in extensive physical and psychological benefits for both the mother and the newborn. However, the rate and duration of exclusive breastfeeding (EBF) remains low worldwide. Mother-infant skin-to-skin contact (SSC) immediately after birth has demonstrated results that support the argument for breastfeeding continuation. Research aim: This study aimed to investigate the prevalence of EBF 3 months postpartum and the effect of early SSC in maintaining optimal EBF practices for mothers and their healthy newborns...

The structurally complex oligomeric proanthocyanidins (OPACs) are promising biomimetic agents, capable of strengthening the macromolecular backbone of teeth via intermolecular and intermicrofibrillar cross-linking. This study establishes analytical methods capable of determining the absolute configuration of the catechin-type monomeric units of underivatized OPACs. This preserves the capacity of their biological evaluation, aimed at understanding the inevitably stereospecific interactions between the OPACs and dentin collagen...

Adaptation of prions to new species is thought to reflect the capacity of the host-encoded cellular form of the prion protein (PrP(C)) to selectively propagate optimized prion conformations from larger ensembles generated in the species of origin. Here we describe an alternate replicative process, termed nonadaptive prion amplification (NAPA), in which dominant conformers bypass this requirement during particular interspecies transmissions. To model susceptibility of horses to prions, we produced transgenic (Tg) mice expressing cognate PrP(C) Although disease transmission to only a subset of infected TgEq indicated a significant barrier to EqPrP(C) conversion, the resulting horse prions unexpectedly failed to cause disease upon further passage to TgEq...

Mixtures of zinc oxide with carbon nanoparticles, ZnO + xC (x = 0.1%, 1% and 3% by weight), were subjected to mechanical processing (MP) in a hermetically sealed grinding chamber. Using electron paramagnetic resonance (EPR) spectroscopy, we monitored the evolution of spin centers in CNPs. While the initial CNPs were EPR silent, their short-duration MP (tMP) gave rise to emergence of low-intensity carbon signal. Increasing the sample temperature at tMP > 9 min induced CNP oxidation, which lead to a dramatic increase in the intensity of C signal...

OBJECTIVES: The burden of pneumococcal disease is measured only through patients with invasive pneumococcal disease. The urinary antigen test (UAT) for pneumococcus has exhibited a high sensitivity and specificity. We aimed to compare the pneumococcal pneumonias diagnosed as invasive disease with pneumococcal pneumonias defined by UAT. METHODS: Prospective observational study on consecutive non-immunosuppressed patients with community-acquired pneumonia from January 2000 to December 2014...

Many epidemiological studies have used proximity to sources as air pollution exposure assessment method. However, proximity measures are not generally good surrogates because of their complex non-linear relationship with exposures. Neuro-fuzzy inference systems (NFIS) can be used to map complex non-linear systems, but its usefulness in exposure assessment has not been extensively explored. We present a novel approach for exposure assessment using NFIS, where the inputs of the model were easily-obtainable proximity measures, and the output was residential exposure to an air pollutant...

Carbon dioxide (CO2) molecules show a rich orientation landscape when they are enclathrated in type I hydrates. Previous studies have described experimentally their preferential orientations, and some theoretical works have explained, but only partially, these experimental results. In the present paper, we use classical molecular dynamics and electronic density functional theory to advance in the theoretical description of CO2 orientations within type I hydrates. Our results are fully compatible with those previously reported, both theoretical and experimental, the geometric shape of the cavities in hydrate being, and therefore, the steric constraints, responsible for some (but not all) preferential angles...

Chiral fullerene-metal hybrids with complete control over the four stereogenic centers, including the absolute configuration of the metal atom, have been synthesized for the first time. The stereochemistry of the four chiral centers formed during [60]fullerene functionalization is the result of both the chiral catalysts employed and the diastereoselective addition of the metal complexes used (iridium, rhodium, or ruthenium). DFT calculations underpin the observed configurational stability at the metal center, which does not undergo an epimerization process...

BACKGROUND: Social inequities in healthcare are known to exist for the management of many chronic diseases in France, including diabetes. The recession that began in 2008 has led to increased income disparities but has it also exacerbated health inequities. The aim of this study was to describe trends in inequities in diabetes-related healthcare between 2008 and 2011 in the PACA region (Provence-Alpes-Côte-d'Azur). METHODS: This analysis used two sources of data: the regional national health insurance fund (PACA region) reimbursement database and the socio-demographic databases of the national statistics office (INSEE) for four full years (2008 to 2011)...

Skeletal muscle is a plastic tissue during development with distinctive acute and chronic response to maternal protein restriction. This study evaluated gene and protein expression of key-enzymes of glycolytic pathway (HK2, PFK, PDK4 and CS), and fatty acid oxidation (CPT1 and β-HAD) of two different types of skeletal muscle [soleus and extensor digitorium longus (EDL)] from offspring rats at 30 and 90 days of age, exposed to maternal isoenergetic low protein diet throughout gestation and lactation. Pups from dams fed 17% protein diet (n=5, normal protein, Np), and low protein pups from dams fed 8% casein diet (low protein, Lp, n=5) were evaluated...

REVIEW
Miguel Vidal, Katharzina Starowicz
Hematopoiesis, the process by which blood cells are continuously produced, is one of the best studied differentiation pathways. Hematological diseases are associated to reiterated mutations in genes encoding important gene expression regulators, including chromatin regulators. Among them, the Polycomb group (PcG) of proteins is an essential system of gene silencing involved in the maintenance of cell identities during differentiation. PcG proteins assemble into two major types of Polycomb repressive complexes (PRC) endowed with distinct histone tail modifying activities...
