More than 400 seal mummies and skeletons are now mapped in the northern part of James Ross Island, Antarctica. Decomposing carcasses represent a rare source of both organic matter and associated elements for the soil. Owing to their high trophic position, seals are known to carry a significant mercury body burden. This work focuses on the extent of the mercury input from seal carcasses and shows that such carcasses represent locally significant sources of mercury and methylmercury for the environment. Mercury contents in soil samples from the surrounding areas were determined using a single-purpose AAS mercury analyzer...

People living with chronic inflammatory bowel disease (IBD) experienced that knowledge about their embodied tolerance limits, diet, mental problem solving, and change in lifestyle together with integrative health care could promote recovery from their diagnosed disease in calmer periods of suffering. A hermeneutic approach was used to analyze interviews with patients living with IBD outside hospitals. Thirteen young adults between 18 and 45 years of age in calmer phases of IBD participated in the study. Three main themes emerged from the analysis of the interviews: (1) Understanding limits in embodied tolerance, (2) Restoring balance is creating a new equilibrium, and (3) Creating resilience through integrative care...

PURPOSE: Accurate reconstruction of the dose delivered by (90)Y microspheres using a postembolization PET scan would permit the establishment of more accurate dose-response relationships for treatment of hepatocellular carcinoma with (90)Y. However, the quality of the PET data obtained is compromised by several factors, including poor count statistics and a very high random fraction. This work uses Monte Carlo simulations to investigate what impact factors other than low count statistics have on the quantification of (90)Y PET...

In moving beyond the second row of the periodic table for molecules of astronomical and atmospheric significance, the exploration of sulfur and phosphorus chemistry is essential. Additionally, silicon is abundant in most astrophysical environments and is a major component of most rocky bodies. The triatomic molecule composed of each of these atoms is therefore a tantalizing candidate for spectroscopic characterization for astrophysical reasons as well as gaining further understanding into the chemical physics of molecules that are not carbon-based...

The thermal decomposition of syn-ethanal-oxide (syn-CH3CHOO) through vinyl hydrogen peroxide (VHP) leading to hydroxyl radical is characterized using a modification of the HEAT thermochemical protocol. The isomerization step of syn-CH3CHOO to VHP via a 1,4 H-shift, which involves a moderate barrier of 72 kJ/mol, is found to be rate determining. A two-dimensional master equation approach, in combination with semi-classical transition state theory, is employed to calculate the time evolution of various species as well as to obtain phenomenological rate coefficients...

Previous works usually report greater postural stability in precise visual tasks (e.g., gaze-shift tasks) than in stationary-gaze tasks. However, existing cognitive models do not fully support these results as they assume that performing an attention-demanding task while standing would alter postural stability because of the competition of attention between the tasks. Contrary to these cognitive models, attentional resources may increase to create a synergy between visual and postural brain processes to perform precise oculomotor behaviors...

There is a large body of work evidencing the necessity to evaluate chemical speciation dynamics of trace metals in solution for an accurate definition of their bioavailability to microorganisms. In contrast, the integration of intracellular metal speciation dynamics in biouptake formalisms is still in its early stages. Accordingly, we elaborate here a rationale for the interplay between chemodynamics of intracellular metal complexes and dynamics of processes governing metal biouptake under non-complexing outer medium conditions...

BACKGROUND: A growing body of evidence links socioeconomic status (SES) to children's brain structure. Few studies, however, have specifically investigated relations of SES to white matter structure. Further, although several studies have demonstrated that family SES is related to development of brain areas that support executive functions (EF), less is known about the role that white matter structure plays in the relation of SES to EF. One possibility is that white matter differences may partially explain SES disparities in EF (i...

Acute and chronic alcohol exposure evidently influences epigenetic changes, both transiently and permanently, and these changes in turn influence a variety of cells and organ systems throughout the body. Many of the alcohol-induced epigenetic modifications can contribute to cellular adaptations that ultimately lead to behavioral tolerance and alcohol dependence. The persistence of behavioral changes demonstrates that long-lasting changes in gene expression, within particular regions of the brain, may contribute importantly to the addiction phenotype...

In this work, an innovative methodology for the treatment of landfill leachates, after aerobic lagooning, is proposed and adjusted at pilot-scale. This methodology involves an aerobic activated sludge biological pre-oxidation (ASBO), a coagulation/sedimentation step (240mgFe(3+)/L, at pH4.2) and a photo-oxidation through a photo-Fenton (PF) reaction (60mg Fe(2+), at pH2.8) combining solar and artificial light. The ASBO process applied to a leachate after aerobic lagooning, with high organic and nitrogen content (1...

Global warming and predation risk can have important impacts on animal physiology and life histories that can have consequences for ecosystem function. Zhang et al. () recently tested the separate and interactive effects of warming and predation risk on the body composition of Daphnia magna. By measuring both the elemental and biochemical composition of individuals, they showed that D. magna body elemental composition responded opposite to theoretical predictions and previous studies but that these changes were explained by adaptive life-history shifts in allocation to protein in eggs versus body lipid reserves...

Ambient mass spectrometry imaging has become an increasingly powerful technique for the direct analysis of biological tissues in the open environment with minimal sample preparation and fast analysis times. In this study, we introduce desorption electrospray ionization mass spectrometry imaging (DESI-MSI) as a novel, rapid, and sensitive approach to localize the accumulation of a mildly toxic ionic liquid (IL), AMMOENG 130 in zebrafish (Danio rerio). The work demonstrates that DESI-MSI has the potential to rapidly monitor the accumulation of IL pollutants in aquatic organisms...

We present the first numerical simulation setup for the calculation of the acoustic viscous torque on arbitrarily shaped micro-particles inside general acoustic fields. Under typical experimental conditions, the particle deformation plays a minor role. Therefore, the particle is modeled as a rigid body which is free to perform any time-harmonic and time-averaged translation and rotation. Applying a perturbation approach, the viscoacoustic field around the particle is resolved to obtain the time-averaged driving forces for a subsequent acoustic streaming simulation...

Antibody drug is a kind of glycoprotein which molecular weight is over one hundred thousand. The number of pharmaceutical approval of antibody drug has been increasing in recent years. In terms of a working mechanism and pharmacokinetics, antibody drug is markedly different from existing low molecular weight drugs. In prospect, about body kinetics is the same. This paper describes general features of antibody drug mainly about internal kinetics in the first half. In the last half, body kinetics of human anti-RANKL monoclonal antibody called Denosumab and body kinetics changes in special population are outlined...

OBJECTIVES: To examine the evolution of the concept of the symptom cluster through literature synthesis and identify knowledge gaps. DATA SOURCES: Published literature. CONCLUSION: A robust body of research has developed showing that clusters of symptoms can be identified empirically with modest evidence of convergence across methods. The science would benefit from a coordinated effort of qualitative studies to ensure that appropriate symptoms are evaluated; empirical symptom cluster identification studies building upon qualitative work; and subgroup identification studies based on empirically defined symptom clusters...
