F Vida Zohoori, A Maguire
The urinary fluoride/creatinine ratio (UF/Cr) in a spot urine sample could be a useful systemic F exposure monitoring tool. No reference value for UF/Cr currently exists, therefore this study aimed to establish an upper reference value for a UF/Cr, corresponding to excessive systemic F exposure, i.e., >0.07 mg F/kg body weight (b.w.)/day, in children. Subsidiary aims were to examine the relationship between (i) total daily F intake (TDFI) and 24-h urinary F excretion (DUFE); (ii) DUFE and UF/Cr, and (iii) TDFI and UF/Cr...

Moisture content (MC) is one of the most important quality parameters of green coffee beans. Therefore, its fast and reliable measurement is necessary. This study evaluated the feasibility of near infrared (NIR) spectroscopy and chemometrics for rapid and non-destructive prediction of MC in intact green coffee beans of both Coffeaarabica (Arabica) and Coffeacanephora (Robusta) species. Diffuse reflectance (log 1/R) spectra of intact beans were acquired using a bench top Fourier transform NIR instrument. MC was determined gravimetrically according to The International Organization for Standardization (ISO) 6673...

In see-through systems an observer watches a (background) scene partially occluded by a display. In this display, usually positioned close to the observer, a region of the background scene is shown, yielding the sensation that the display is transparent. To achieve the transparency effect, it is very important to compensate the parallax error and other distortions caused by the image acquisition system. In this paper a detailed study of a video see-through methodology with parallax correction is performed. In a system composed by two cameras - one directed to the user and another to the background scene - and a display, the relative position between the user, the display and the scene is estimated using a feature detection algorithm and the parallax error is compensated assuming a planar scene model...

BACKGROUND: Suboptimal blood pressure (BP) control is commonly observed in patients receiving antihypertensive agents, but the relationship between uncontrolled BP and left atrial (LA) impairment remains unknown. METHODS: This study enrolled 279 hypertensive patients who had been medicated, as well as 85 matched normal controls. The BP of systolic <140 mmHg and diastolic<90 mmHg was defined as optimal (HT1 group, n=146), otherwise as suboptimal BP control (HT2 group, n = 133)...

BACKGROUND: Several disc disease nomenclatures and approaches for LDH exist. The traditional midline bone-destructive procedures together with approaches requiring extreme muscular retraction are being replaced by muscle sparing, targeted, stability-preserving surgical routes. The increasing speculation on LDHs and the innovative corridors described to treat them have lead to an extensive production of papers frequently treating the same topic but adopting different terminologies and reporting contradictory results...

The transformation of a European guideline (2013/59/Euratom) from 2013 into national law requires adaptation of the national statutory regulations. This year, all areas of protection from ionizing radiation will be subject to the new radiation protection law (StrlSchG). Through this, the German X‑ray and Radiation Protection Acts will be combined to form a higher level of authority. The main parts of the StrlSchG will receive a new classification and will be organized according to the exposure scenario: radiation protection in planned exposure scenarios, radiation protection in emergency exposure scenarios, radiation protection in existing exposure scenarios, and the regulation of overall exposure scenarios...

Human behavior is strongly affected by culturally transmitted norms and values. Certain norms are internalized (i.e., acting according to a norm becomes an end in itself rather than merely a tool in achieving certain goals or avoiding social sanctions). Humans' capacity to internalize norms likely evolved in our ancestors to simplify solving certain challenges-including social ones. Here we study theoretically the evolutionary origins of the capacity to internalize norms. In our models, individuals can choose to participate in collective actions as well as punish free riders...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...

There is a dearth of scholarly analysis and critique of the Australian newsprint media's role in the medicalization of child behaviour. To begin to redress this lack this paper analyses newsprint media's use of metaphors that re/describe and construct realities of ADHD with a medicalizing effect. The interdisciplinary team used the Factiva(TM) database to locate and review 453 articles published in Australian national and metropolitan newspapers during the decade 1999-2009. Data analysis involved generating statistical descriptions of the dataset according to attributes such as: date, state, newspaper titles and author names...

Patulin is a water-soluble mycotoxin produced by several species of fungi. Governmental bodies have placed it under scrutiny for its potential negative health effects, and maximum residue limits are fixed in specific food matrices to protect consumers' health. Confirmatory analysis of patulin in complex food matrices can be a difficult task, and sample clean-up treatments are frequently necessary before instrumental analyses. With the aim of simplifying the clean-up step, we prepared a 256-member combinatorial polymeric library based on 16 functional monomers, four cross-linkers and four different porogenic solvents...

Miniproteins simplify the protein-folding problem, allowing the dissection of forces that stabilize protein structures. Here we describe PPα-Tyr, a designed peptide comprising an α-helix buttressed by a polyproline II helix. PPα-Tyr is water soluble and monomeric, and it unfolds cooperatively with a midpoint unfolding temperature (TM) of 39 °C. NMR structures of PPα-Tyr reveal proline residues docked between tyrosine side chains, as designed. The stability of PPα is sensitive to modifications in the aromatic residues: replacing tyrosine with phenylalanine, i...

An efficient strategy for the synthesis of high-purity lactulose through chemical isomerization of lactose was developed using recyclable catalyst sodium aluminate. Maximum yield of 85.45±1.79% was obtained from 35% (w/v) of lactose using a 1:1M ratio of NaAlO2-lactose after reaction at 60°C and pH 12 for 50min, with a purity ratio (Pu) of approximately 95%. Al(OH)3 precipitation from lactulose syrup through pH adjustment showing a superior decolorizing efficiency was implemented, which simplified the removal of catalyst and provided a convenient approach to achieve catalyst recovery...

Demographic changes in contemporary society require implementation of proper perioperative care of elderly patients due to an increased risk of perioperative complications in this group. Preoperative assessment of health status identifies risks and enables preventive interventions, improving outcomes of surgical treatment. The Comprehensive Geriatric Assessment contains numerous diagnostic tests and consultations, which is expensive and difficult to use in everyday practice. The development of a simplified model of perioperative assessment of elderly patients will help identifying the group of patients who require further diagnostic workup...

Examination of the current the American College of Cardiology/American Heart Association (ACC/AHA) and European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines on the prevention of cardiovascular disease and the management of dyslipidemias finds much common ground. Both note that Atherosclerotic cardiovascular disease (ASCVD) is, in most people, the product of a number of risk factors, notably tobacco exposure, hyperlipidemia, hypertension, inactivity, overweight and diabetes. They stress that risk calculators can help in the assessment of risk in apparently healthy persons...

PREMISE OF THE STUDY: High-throughput sequencing of genomic DNA can recover complete chloroplast genome sequences, but the sequence data are usually dominated by sequences from nuclear/mitochondrial genomes. To overcome this deficiency, a simple enrichment method for chloroplast DNA from small amounts of plant tissue was tested for eight plant species including a gymnosperm and various angiosperms. METHODS: Chloroplasts were enriched using a high-salt isolation buffer without any step gradient procedures, and enriched chloroplast DNA was sequenced by multiplexed high-throughput sequencing...
