Identification of Saccharomyces cerevisiae Genes Involved in the Resistance to Phenolic Fermentation Inhibitors.
Saccharomyces cerevisiae was exposed to inhibitory concentrations of the three phenolic phenylpropanoids: coniferyl aldehyde, ferulic acid, and isoeugenol. Deoxyribonucleic acid microarray analysis was employed as one approach to generate a set of candidate genes for deletion mutant analysis to determine the potential contribution of the corresponding gene products to the resistance against toxic
Multimethod 3D characterization of natural plate-like nanoparticles: shape effects on equivalent size measurements
The fundamental properties and processes that govern nanoparticle behavior in colloidal dispersions are critical to predict their performance in applications and also their environmental and health implications. Illite is a platy clay mineral that is present in large amounts in aquatic environments and can be used as a model natural particle for environmental risk assessment. However, the high-asp
Variants at APOE Influence Risk of Deep and Lobar Intracerebral Hemorrhage
Objective: Prior studies investigating the association between APOE alleles epsilon 2/epsilon 4 and risk of intracerebral hemorrhage (ICH) have been inconsistent and limited to small sample sizes, and did not account for confounding by population stratification or determine which genetic risk model was best applied. Methods: We performed a large-scale genetic association study of 2189 ICH cases an
Miniaturized and Automated High-Throughput Verification of Proteins in the ISET Platform with MALDI MS.
A major bottleneck in high-throughput protein production is the validation step, which is why parallel and automated sample processing methods are highly desirable. Also, a miniaturized sample preparation format is preferred, as the reduction of reagent volumes significantly decreases the analysis cost per sample. We have developed an automated and miniaturized protein sequence verification protoc

Biological Sunscreens Tune Polychromatic Ultraviolet Vision in Mantis Shrimp
Stomatopod crustaceans, or mantis shrimp, are renowned for their complex visual systems. Their array of 16 types of photoreceptors provides complex color reception, as well as linear and circular polarization sensitivity [1-6]. The least-understood components of their retina are the UV receptors, of which there are up to six distinct, narrowly tuned spectral types [4]. Here we show that in the sto
Petrological discrimination among Precambrian dyke swarms: eastern Kaapvaal craton (South Africa)
Age-determinations on a complex array of mafic dykes across the eastern Kaapvaal craton (Olsson et al.. 2010) are complemented herein by field evidence, dyke trend analysis, and petrological characterization of 58 dyke samples. similar to 2.95 Ga SE-trending, a similar to 2.65 Ga E- to SE-radiating, and similar to 1.90 Ga NE-trending swarms can be distinguished. Prominent Archean (similar to 2.95
The nasal mucosa contains a large diversity of human papillomavirus from the Beta- and Gammapapillomavirus genera.
Background. Human papillomavirus (HPV) types from the Beta- and Gammapapillomavirus genera are common at cutaneous sites. The aim of this study was to analyze the prevalence of these HPV types in oral and nasal samples.Methods. Nasal and oral samples were taken from 312 volunteers of Danish health-care staff (240 women and 72 males, with mean age of 42 years). Of these 311 oral and 304 nasal sampl
Equivocation for the Objective Bayesian
According to Williamson (In defense of objective Bayesianism, Oxford University Press, Oxford, 2010), the difference between empirical subjective Bayesians and objective Bayesians is that, while both hold reasonable credence to be calibrated to evidence, the objectivist also takes such credence to be as equivocal as such calibration allows. However, Williamson's prescription for equivocation gener

State responsibility beyond borders: what legal basis for Italy's push-backs to Libya?
This article takes Italy’s widely-debated 2009 push-backs to Libya campaign as a point of reference to address whether bilateral agreements for technical and police cooperation provide the legal foundation for the forced return of intercepted refugees to countries of embarkation. Through a detailed analysis of both the facts and the texts of the published and unpublished bilateral accords, it conc
Extracellular Histones Induce Chemokine Production in Whole Blood Ex Vivo and Leukocyte Recruitment In Vivo.
The innate immune system relies to a great deal on the interaction of pattern recognition receptors with pathogen- or damage-associated molecular pattern molecules. Extracellular histones belong to the latter group and their release has been described to contribute to the induction of systemic inflammatory reactions. However, little is known about their functions in the early immune response to an
Effects of the buffering capacity of the soil on the mobilization of heavy metals. Equilibrium and kinetics.
Understanding the possible pH-buffering processes is of maximum importance for risk assessment and remediation feasibility studies of heavy-metal contaminated soils. This paper presents the results about the effect of the buffering capacity of a polluted soil, rich in carbonates, on the pH and on the leaching evolution of its main contaminant (lead) when a weak acid (acetic acid) or a strong one (
With that diet, you will go far: trait-based analysis reveals a link between rapid range expansion and a nitrogen-favoured diet
Recent global change has had a substantial influence on the distribution of organisms, and many species are currently expanding their ranges. To evaluate the underlying processes, long-term data with good geographic resolution are essential. One important but generally overlooked data source is offered by the taxon-specific national catalogues of first provincial records that are kept in many coun
On icing and icing mitigation of wind turbine blades in cold climate
A review on icing physics, ice detection, anti-icing and de-icing techniques for wind turbines in cold climate has been performed. Typical physical properties of atmospheric icing and the corresponding meteorological parameters are presented. For computational modeling of ice accretion on turbine blades, the LEWINT code was adopted to simulate ice accretion on an aerofoil for a 2 MW wind turbine.
Double ionization probed on the attosecond timescale
Double ionization following the absorption of a single photon is one of the most fundamental processes requiring interaction between electrons(1-3). Information about this interaction is usually obtained by detecting emitted particles without access to real-time dynamics. Here, attosecond light pulses(4,5), electron wave packet interferometry(6) and coincidence techniques(7) are combined to measur
Global arginine bioavailability, a marker of nitric oxide synthetic capacity, is decreased in PTSD and correlated with symptom severity and markers of inflammation.
Psychiatric, physical and biological aspects of posttraumatic stress disorder (PTSD) may be associated with dysfunctions in several cellular processes including nitric oxide (NO) production. NO is synthesized from arginine in a reaction carried out by NO synthase (NOS) enzymes. The recently introduced "global arginine bioavailability ratio" (GABR; ratio of arginine to [ornithine+ citrulline]) has
Metastatic sites and survival in lung cancer.
Population-based data on metastatic sites and survival in site-specific metastases are lacking for lung cancer and for any cancer because most cancer registries do not record metastases. This study uses a novel population-based approach to identify metastases from both death certificates and national inpatient data to describe metastatic pathways in lung cancer patients.
