#1
C Reimann, P Filzmoser, K Hron, P Kynčlová, R G Garrett
Most data in environmental sciences and geochemistry are compositional. Already the unit used to report the data (e.g., μg/l, mg/kg, wt%) implies that the analytical results for each element are not free to vary independently of the other measured variables. This is often neglected in statistical analysis, where a simple log-transformation of the single variables is insufficient to put the data into an acceptable geometry. This is also important for bivariate data analysis and for correlation analysis, for which the data need to be appropriately log-ratio transformed...

The recycling of biosolids and livestock manure in agriculture may lead to the introduction of antibiotic residues, i.e., parent molecule and transformation products, into amended soils. Their fate in soils can be approached through the assessment of their environmental availability. In this work, the environmental availability of sulfamethoxazole (SMX) and three transformation products (N(4)-acetyl-SMX, 3-amino-5-methylisoxazole, aniline) was assessed in soils amended with sludge compost or cow manure throughout a three-month incubation, using soft extractions with CaCl2, EDTA or cyclodextrin solutions...

By measuring levels of tolerance to toxicants in microbial communities using functional toxicity tests under controlled conditions, pollution-induced community tolerance (PICT) approaches offer an effect-based tool to assess the ecological risk of chemicals in aquatic systems. However, induced tolerance of exposed microbial communities cannot always be attributed solely to the presence of toxicants as various environmental factors, such as temperature, can also be involved. Several PICT studies have been conducted to assess the effects of copper (Cu) on phototrophic periphyton, but little is known about the influence of temperature on the response of these microbial communities to acute and chronic exposure to Cu...

Generic and specific determination among the Laurencia complex is a challenging task. DNA barcoding combined with phenotypic investigations are mandatory for species differentiation. In this study, two morphologically different members of the Laurencia complex were investigated using untargeted (1) H NMR-based metabolomics. Twenty-one population samples were collected in order to evaluate both temporal and geographical homogeneity. Data obtained from (1) H NMR analysis followed by statistical analysis allowed a clear separation of all the samples into two groups...

BACKGROUND: Extravasation injury, a complication commonly seen in the neonatal intensive care unit, can result in scarring with cosmetic and functional sequelae. A wide variety of treatments are available, including subcutaneous irrigation with saline (with or without hyaluronidase), liposuction, use of specific antidotes, topical applications, and normal wound care with dry or wet dressings. All such treatments aim to prevent or reduce the severity of complications. OBJECTIVES: Primary objective To compare the efficacy and safety of saline irrigation or saline irrigation with prior hyaluronidase infiltration versus no intervention or normal wound care for tissue healing in neonates with extravasation injury...

AIMS: The standard sensor for abdominal pressure (Pabd) measurement in urodynamics (UD) is a rectal sensor. In patients where the rectum is not available due to prior surgery or when external anal sphincter (EAS) tone is poor, rectal sensor may slip, making Pabd recording unreliable. Vaginal Pabd measurement and wireless vaginal sensors have been tried. We present our preliminary series of a novel nasogastric tube (NG) sensor for Pabd measurement. METHODS: We identified patients undergoing UD with a NG Pabd sensor from a prospectively maintained UD database of a tertiary care urological center between July 2013 and December 2016...

Broadening clinical evidence has markedly designated inositol(s) as a common and effective therapeutic approach for PCOS and infertility. Although considerable research has been focused on the use in clinical practice of myo-inositol (myo-ins) and D-chiro-inositol (D-chiro-ins), the two major inositol stereoisomers, less attention has been paid to their bioavailability. Therefore, the aim of this paper is to gather and analyze information on inositol(s) bioavailability, to better delineate its optimal concentration for scientific and clinical purposes...

OBJECTIVE: Insulin resistance (IR) is a common disorder, which can impair female fertility and is characterized by phenotypic heterogeneity. Life-style treatment and insulin sensitizers are commonly used in the management of women with IR and consequent hyperinsulinemia, in order to restore the normal endocrinological and clinical parameters. Metformin (MET) is considered one of the first approaches to this pathology but new evidences are showing promising results using myo-inositol (MYO) in the management of this pathology...

Numerous iron-containing preparations are available on the market; these vary in dosage, salt, chemical state of iron (ferric or ferrous) and in the iron delivery process (immediate or prolonged-release). Tardyferon® is a prolonged-release tablet containing 80 mg ferrous sulphate. The formulation has recently been modified; changes to the excipients which constitute the inert formulation matrix have allowed a decrease in tablet size for easier swallowing. The aim of this multicenter open-label study was to characterize the serum pharmacokinetics of iron in non-pregnant women aged 23-45 years with iron deficiency anaemia (IDA) following single oral administration of 160 mg Tardyferon® under fasting conditions...

Importance: The issue of the aging physician and when to cease practice has been controversial for many years. There are reports of prominent physicians who practiced after becoming dangerous in old age, but the profession has not demonstrated the ability to prevent this. A mandatory retirement age could be discriminatory and take many competent physicians out of practice and risk a physician shortage. An increasing body of evidence regarding the relationship between physicians' age and performance has led organizations, such as the American College of Surgeons, to revisit this challenge...

Conservation planning information is important for identifying options for watershed water quality improvement and can be developed for use at field, farm, and watershed scales. Translation across scales is a key issue impeding progress at watershed scales because watershed improvement goals must be connected with implementation of farm- and field-level conservation practices to demonstrate success. This is particularly true when examining alternatives for "trap and treat" practices implemented at agricultural-field edges to control (or influence) water flows through fields, landscapes, and riparian corridors within agricultural watersheds...

Wildland fire can alter mercury (Hg) cycling on land and in adjacent aquatic environments. In addition to enhancing local atmospheric Hg redeposition, fire can influence terrestrial movement of Hg and other elements into lakes via runoff from burned upland soil. However, the impact of fire on water quality and the accumulation of Hg in fish remain equivocal. We investigated the effects of fire-specifically, a low-severity prescribed fire and moderate-severity wildfire-on young-of-the-year yellow perch () and lake chemistry in a small remote watershed in the Boundary Waters Canoe Area Wilderness in northeastern Minnesota...

Urbanization affects ecosystem function and environmental quality through shifts in ecosystem fluxes that are brought on by features of the built environment. Green infrastructure (GI) has been suggested as a best management practice (BMP) to address urban hydrologic and ecological impacts of the built environment, but GI practice has only been studied from a limited set of climatic conditions and disciplinary approaches. Here, we evaluate GI features in a semiarid city from the perspective of soil ecology through the application of soil nematode community analysis...

The unique physical and chemical properties of biochars make them promising materials for odor, gas, and nutrient sorption. Floating covers made from organic materials (biocovers) are one option for reducing odor and gas emissions from livestock manure lagoons. This study evaluated the potential of floating biochar covers to reduce odor and gas emissions while simultaneously sorbing nutrients from liquid dairy manure. This new approach has the potential to mitigate multiple environmental problems. Two biochars were tested: one made via gasification of Douglas fir chips at 650°C (FC650), and the other made from a mixture of Douglas fir [ (Mirb...

The leaf spotting diseases in wheat that include Septoria tritici blotch (STB) caused by , Stagonospora nodorum blotch (SNB) caused by , and tan spot (TS) caused by pose challenges to breeding programs in selecting for resistance. A promising approach that could enable selection prior to phenotyping is genomic selection that uses genome-wide markers to estimate breeding values (BVs) for quantitative traits. To evaluate this approach for seedling and/or adult plant resistance (APR) to STB, SNB, and TS, we compared the predictive ability of least-squares (LS) approach with genomic-enabled prediction models including genomic best linear unbiased predictor (GBLUP), Bayesian ridge regression (BRR), Bayes A (BA), Bayes B (BB), Bayes Cπ (BC), Bayesian least absolute shrinkage and selection operator (BL), and reproducing kernel Hilbert spaces markers (RKHS-M), a pedigree-based model (RKHS-P) and RKHS markers and pedigree (RKHS-MP)...
