First-trimester euploid miscarriages analysed by array-CGH
submitted by lhat 9 minutes ago - Topic: Biology
It is estimated that 10–15 % of all clinically recognised pregnancies results in a miscarriage, most of which occur during the first trimester. Large-scale chromosomal abnormalities have been found in up to 50 % of first-trimester spontaneous abortions and, for several decades, standard cytog...



Association of two SNPs in the coding region of the insulin-like growth factor 1 receptor (IGF1R) gene with growth-related traits in Angus cattle
submitted by lhat 9 minutes ago - Topic: Biology
The insulin-like growth factor 1 (IGF-1) is considered to be a factor that mainly regulates growth, differentiation, and the maintenance of various function in numerous tissues through binding to a family of transmembrane tyrosine kinase receptors, signaling primarily through the insulin-like gro...

Transgenic pigs designed to express human α-galactosidase to avoid humoral xenograft rejection
submitted by lhat 9 minutes ago - Topic: Biology
The use of animals as a source of organs and tissues for xenotransplantation can overcome the growing shortage of human organ donors. However, the presence of xenoreactive antibodies in humans directed against swine Gal antigen present on the surface of xenograft donor cells leads to the compleme...

Soil contamination by phthalate esters in Chinese intensive vegetable production systems with different modes of use of plastic film
submitted by loeloempix 11 minutes ago - Topic: Environment
The concentrations of six priority phthalic acid esters (PAEs) in intensively managed suburban vegetable soils in Nanjing, east China, were analyzed using gas chromatography–mass spectrometry (GC–MS). The total PAE concentrations in the soils ranged widely from 0.15 to 9.68 mg kg−1 with a...

Interactions of tetracycline with Cd (II), Cu (II) and Pb (II) and their cosorption behavior in soils
submitted by loeloempix 11 minutes ago - Topic: Environment
Tetracycline (TC), a common antibiotic, can behave as an efficient ligand with cations, but the effect of its interaction with heavy metal cations on the mobility of both species in soils has not been well evaluated. In this study, the complexation affinities of TC with Cd (II), Cu (II) and Pb (I...



Oxidation of nonylphenol and octylphenol by manganese dioxide: Kinetics and pathways
submitted by loeloempix 11 minutes ago - Topic: Environment
Due to their potent estrogenicity and ubiquitous occurrence, non-ionic surfactant metabolites nonylphenol (NP) and octylphenol (OP) are of significant concern. Abiotic chemical oxidation by naturally abundant metal oxides may be an important route of their environmental attenuation, but is poorly...

Upwind impacts of ammonia from an intensive poultry unit
submitted by loeloempix 11 minutes ago - Topic: Environment
This study investigated potential ammonia impacts on a sand dune nature reserve 600 m upwind of an intensive poultry unit. Ammonia concentrations and total nitrogen deposition were measured over a calendar year. A series of ammonia and nitrogen exposure experiments using dune grassland species w...

Contribution of a submerged membrane bioreactor in the treatment of synthetic effluent contaminated by Bisphenol-A: Mechanism of BPA removal and membrane fouling
submitted by loeloempix 11 minutes ago - Topic: Environment
A submerged membrane bioreactor has been operated at the laboratory scale for the treatment of a synthetic effluent containing Bisphenol-A (BPA). COD, NH4–N, PO4–P and BPA were eliminated respectively, at 99%, 99%, 61% and 99%. The increase of volumetric loading rate from 0 to 21.6 g/m3/d di...

An intermediate complexity dynamic model for predicting accumulation of atmospherically-deposited metals (Ni, Cu, Zn, Cd, Pb) in catchment soils: 1400 to present
submitted by loeloempix 11 minutes ago - Topic: Environment
The Intermediate Dynamic Model for Metals (IDMM) is a model for prediction of the pools of metals (Ni, Cu, Zn, Cd, Pb) in topsoils of catchments resulting from deposition of metals from the atmosphere. We used the model to simulate soil metal pools from 1400 onwards in ten UK catchments comprisin...

Health effects of daily airborne particle dose in children: Direct association between personal dose and respiratory health effects
submitted by loeloempix 11 minutes ago - Topic: Environment
Air pollution is a widespread health problem associated with respiratory symptoms. Continuous exposure monitoring was performed to estimate alveolar and tracheobronchial dose, measured as deposited surface area, for 103 children and to evaluate the long-term effects of exposure to airborne partic...

Bridging the gap between traffic generated health stressors in urban areas: Predicting xylene levels in EU cities
submitted by loeloempix 11 minutes ago - Topic: Environment
Many citizens live, work, commute, or visit traffic intensive spaces and are exposed to high levels of chemical health stressors. However, urban conurbations worldwide present monitoring “shortage” – due to economical and/or practical constraints – for toxic stressors such as xylene isome...

Historical arsenic contamination of soil due to long-term phosphate fertiliser applications
submitted by loeloempix 11 minutes ago - Topic: Environment
Archived samples from the Park Grass Experiment, established in 1856, were analysed to determine the impacts of long-term phosphate fertiliser applications on arsenic concentrations in soil and herbage. In plots receiving 35 kg P ha−1 annually (+P), topsoil As concentrations almost doubled f...

Different motor tasks impact differently on cognitive performance of older persons during dual task tests
submitted by rabhawett 12 minutes ago - Topic: Health
Dual task paradigm states that the introduction of a second task during a cognitive or motor performance results in a decreased performance in either task. Treadmill walk, often used in clinical applications of dual task testing, has never been compared to overground walk, to ascertain its suscep...

COMFORT behaviour scale and skin conductance activity: what are they really measuring?
submitted by tkengon 17 minutes ago - Topic: Health
To assess how efficiently the COMFORT behaviour scale measures acute pain in neonates, in comparison to skin conductance activity, a validated measure of pain and stress. Images of 36 newborns were analysed before, during and after painful heel pricks to measure glucose levels and compared to ski...

An international survey of bacterial contamination and householders' knowledge, attitudes and perceptions of hygiene
submitted by mojedh7 19 minutes ago - Topic: Health
This prospective, multinational study was conducted in 20 homes in eight cities or regions in different countries to determine the level of microbiological contamination of common surfaces and items, and investigate the attitudes and perceptions of householders towards cleaning and hygiene. Envir...
