Elena V Piletska, Demi Pink, Kal Karim, Sergey A Piletsky
Patulin is a toxic compound which is found predominantly in apples affected by mould rot. Since apples and apple-containing products are a popular food for the elderly, children and babies, the monitoring of the toxin is crucial. This paper describes a development of a computationally-designed polymeric adsorbent for the solid-phase extraction of patulin, which provides an effective clean-up of the food samples and allows the detection and accurate quantification of patulin levels present in apple juice using conventional chromatography methods...

BACKGROUND: Switchgrass is a crop with many desirable traits for bioenergy production. Plant genomes have high DNA methylation levels throughout genes and transposable elements and DNA methylation is known to play a role in silencing transposable elements. Here we analyzed methylomes in two switchgrass genotypes AP13 and VS16. AP13 is derived from a lowland ecotype and VS16, typically considered drought-tolerant, is derived from an upland ecotype, both genotypes are tetraploid (2n = 4× = 36)...

A full domain control model is established for impurity transportation in the liquid phase, gas-liquid interface and gas phase of silicon to analyze the dynamic mechanics of impurity removal. The results show that the overall mass transfer coefficient mainly depends on the temperature and the chamber pressure. Its value increases with the increase of temperature or the decrease of chamber pressure. Under the same melting condition, the order of the overall mass transfer coefficients for P, Al and Ca is kP > kAl > kCa, indicating that P is easier to remove by evaporation...

With several different imaging options available, it is not surprising that health care providers are unsure which imaging study is most appropriate for evaluating patients who present to the emergency department with abdominal pain. The American College of Radiology, currently, has appropriateness criteria for patients presenting with right upper, right lower, and left lower quadrant pain, and there are different variants for each of these quadrants. Clinicians should be aware of the American College of Radiology appropriateness criteria and, whenever possible, should be using criteria as guide to help them order the most appropriate imaging study...

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is assumed to play a role in mediating neuroplasticity after stroke. Carriers of the function-limiting Val66Met (rs6265) single nucleotide polymorphism (SNP) may have a downregulation in BDNF secretion, which may lead to a poorer prognosis after stroke compared to noncarriers in motor learning and motor function recovery. The present study investigates whether this polymorphism may also affect the recovery of poststroke aphasia (ie, language impairment)...

The plasma kallikrein-kinin system (KKS) consists of serine proteases, prekallikrein (pKal) and factor XII (FXII), and a cofactor, high-MW kininogen (HK). Upon activation, activated pKal and FXII cleave HK to release bradykinin. Activation of this system has been noted in patients with rheumatoid arthritis, and its pathogenic role has been characterized in animal arthritic models. In this study, we generated 2 knockout mouse strains that lacked pKal and HK and determined the role of KKS in autoantibody-induced arthritis...

Previous studies suggest that metabolic disturbances might be involved in the development of osteoarthritis (OA). Associations have been found between the individual components of metabolic syndrome (MetS) and OA. MetS has been associated with increased oxidative stress (OxS). The study aimed to clarify the role of MetS components in OA and to evaluate the levels of OxS in OA patients and in age-matched controls. Fifty-five patients with end-stage OA (age 63 ± 7 years) prior to hip or knee joint replacement surgery and 55 age-, gender- and body mass index matched controls (61 ± 8 years) were enrolled in the study...

INTRODUCTION: Neural tube defects (NTDs) are a group of common and severe congenital birth defects that occur during early embryonic development due to incomplete closure of the neural tube. The genetic architecture of human NTDs, including spina bifida and hydrocephalus, is highly heterogeneous, with multiple genes/loci and both gene-gene and gene-environment interactions involved. Hence, the variation in outcomes also most likely relates to a combination of the severity of different variants in multiple genes and genetic modifiers affecting the biochemical traits...

PMM2-CDG (MIM#212065) is the most common type of congenital disorders of glycosylation (CDG) caused by mutations in PMM2 (MIM#601785). In Estonia, five patients from three families have been diagnosed with PMM2-CDG. Our aim was to evaluate the presence of different PMM2-CDG-causing mutations in a population-based cohort and to calculate the expected frequency of PMM2-CDG in Estonia. Also, we analyzed the prevalence of PMM2-CDG based on our patient group data. To calculate the expected frequency of PMM2-CDG, we used the whole genome sequencing data of 2,244 participants from biobank of the Estonian Genome Center, University of Tartu...

PURPOSE: People without neurological impairments show superior motor learning when they focus on movement effects (external focus) rather than on movement execution itself (internal focus). Despite its potential for neurorehabilitation, it remains unclear to what extent external focus strategies are currently incorporated in rehabilitation post-stroke. Therefore, we observed how physical therapists use attentional focus when treating gait of rehabilitating patients with stroke. METHODS: Twenty physical therapist-patient couples from six rehabilitation centers participated...

Common bean (Phaseolus vulgaris L.) is an important legume, useful for its high protein and dietary fiber. The fungal pathogen Uromyces appendiculatus (Pers.) Unger can cause major loss in susceptible varieties of the common bean. The Ur-3 locus provides race specific resistance to virulent strains or races of the bean rust pathogen along with Crg, (Complements resistance gene), which is required for Ur-3-mediated rust resistance. In this study, we inoculated two common bean genotypes (resistant "Sierra" and susceptible crg) with rust race 53 of U...
