Genetic modification (GM) has been advocated as an alternative or complement to micronutrient interventions such as supplementation, fortification or dietary diversification. While proof-of-concept of various GM biofortified crops looks promising, the decision tree of policy makers is much more complex, and requires insight on their socio-economic impacts: Will it actually work? Is it financially sound? Will people accept it? Can it be implemented in a globalized world? This review shows that GM biofortification could effectively reduce the burden of micronutrient deficiencies, in an economically viable way, and is generally well received by target beneficiaries, despite some resistance and uncertainty...

Fisheries have an enormous economic importance but reconciling their socio-economic features with the conservation and sustainability of marine ecosystems presents major challenges. Bycatch mortality from fisheries is clearly among the most serious global threats for marine ecosystems, affecting a wide range of top predators. Recent estimates report ca. 200,000 seabirds killed annually by bycatch in European waters. However there is an urgent need to rigorously estimate actual mortality rates and quantify effects of bycatch on populations...

Nonlinear registration is an important technique to align two different images and widely applied in medical image analysis. In this paper, we develop a novel nonlinear registration framework based on the diffeomorphic demons, where a reciprocal regularizer is introduced to assume that the deformation between two images is an exact diffeomorphism. In detail, first, we adopt a bidirectional metric to improve the symmetry of the energy functional, whose variables are two reciprocal deformations. Secondly, we slack these two deformations into two independent variables and introduce a reciprocal regularizer to assure the deformations being the exact diffeomorphism...

A major success in personality has been the development of a consensual structure of traits. However, much less progress has been made on the structure of an equally important aspect of human psychology: motives. We present an empirically and theoretically structured hierarchical taxonomy of 161 motives gleaned from a literature review from McDougall to the present and based on the cluster analysis of similarity judgments among these 161 motives, a broader sampling of motives than previous work. At the broadest level were: Meaning, Communion, and Agency...

Until about 1900, large proportions of the world population endured hunger and poverty. The 20th century saw world population increase from 1.6 to 6.1 billion, accompanied and to some extent made possible by rapid improvements in health standards and food supply, with associated advances in agricultural and nutrition sciences. In this paper, I use the application of linear programming (LP) in preparation of rations for farm animals to illustrate a method of calculating the lowest cost of a human diet selected from locally available food items, constrained to provide recommended levels of food energy and nutrients; then, to find a realistic minimum cost, I apply the further constraint that the main sources of food energy in the costed diet are weighted in proportion to the actual reported consumption of food items in that area...

As nations seek to address obesity and diet-related chronic disease, understanding shifts in food intake over time is an imperative. However, quantifying intake of basic foods is not straightforward because of the diversity of raw and cooked wholefoods, processed foods and mixed dishes actually consumed. In this study, data from the Australian national nutrition surveys of 1995 and 2011, each involving more than 12,000 individuals and covering more than 4500 separate foods, were coherently disaggregated into basic foods, with cooking and processing factors applied where necessary...

Maria C Giannakourou, Nikolaos G Stoforos
Traditionally, for the determination of the kinetic parameters of thermal inactivation of a heat labile substance, an appropriate index is selected and its change is measured over time at a series of constant temperatures. The rate of this change is described through an appropriate primary model and a secondary model is applied to assess the impact of temperature. By this approach, the confidence intervals of the estimates of the rate constants are not taken into account. Consequently, the calculated variability of the secondary model parameters can be significantly lower than the actual variability...

BACKGROUND: Intensive Care to facilitate Organ Donation (ICOD) may help to increase the donor pool. We describe the Spanish experience with ICOD. METHODS: ACCORD-Spain consisted of an audit of the donation pathway from patients dead as a result of a devastating brain injury (possible donors) in 68 hospitals during 11/1/2014-4/30/2015. We focused on possible donors whose family was interviewed to discuss organ donation once intensive care with a therapeutic purpose was deemed futile and brain death (BD) was a likely outcome...

This study examined mostly lower-middle-income Latino (37%) and African American (33%) adolescents' (N = 90, Mage = 15.90) conceptions of how U.S. wealth is and ought to be distributed, and whether these judgments are related to adolescents' views about societal and legal fairness and their immediate academic plans. Individually administered multipart interviews assessed conceptions regarding (a) actual and ideal U.S. wealth distribution and related "Rawlsian" judgments, (b) social system and legal fairness, and (c) adolescents' near-term life goals...

In the current study, dual-task performance is examined with multiple-object tracking as a primary task and target-change detection as a secondary task. The to-be-detected target changes in conditions of either change type (form vs. motion; Experiment 1) or change salience (stop vs. slowdown; Experiment 2), with changes occurring at either near (5°-10°) or far (15°-20°) eccentricities (Experiments 1 and 2). The aim of the study was to test whether changes can be detected solely with peripheral vision. By controlling for saccades and computing gaze distances, we could show that participants used peripheral vision to monitor the targets and, additionally, to perceive changes at both near and far eccentricities...

People often filter their experience of new events through knowledge they already have; for example, encoding new events by relying on prototypical event "scripts" at the expense of actual details. Previous research suggests that positive affect often increases this tendency. Three studies assessed whether awe-an emotion elicited by perceived vastness, and thought to promote cognitive accommodation-has the opposite effect, reducing rather than increasing reliance on event scripts. True/false questions on details of a short story about a romantic dinner were used to determine whether awe (a) reduces the tendency to impute script-consistent but false details into memory, and/or (b) promotes memory of unexpected details...

Electrochemical devices for energy conversion and storage are central for a sustainable economy. The performance of electrodes is driven by charge transfer across different layer materials and an understanding of the mechanistics is pivotal to gain improved efficiency. Here, we directly observe the transfer of photogenerated charge carriers in a photoanode made of hematite (α-Fe2O3) and a hydrous iridium oxide (IrOx) overlayer, which plays a key role in photoelectrochemical water oxidation. Through the use of operando X-ray absorption spectroscopy (XAS), we probe the change in occupancy of the Ir 5d levels during optical band gap excitation of α-Fe2O3...

Sensory mismatch between actual motion information and anticipated sensory patterns (internal model) is the etiology of motion sickness (MS). Some evidence supports that hippocampus might involve the neural storage of the "internal model". This study established an "internal model" acquisition-retention behavioral model using a repeated habituation rotation training protocol. We tried to identify the hippocampal subregion involved in "internal model" retention using chemical lesion methods. Hippocampal kinases (CaMK, CaMKIV, CREB and ERK1/2) phosphorylation in the target subregion was assayed and the effects of kinase inhibitors (KN93 or U0126) on "internal model" retention were investigated...

Drilling and handling of permanently frozen soil cores without microbial contamination is of concern because contamination e.g. from the active layer above may lead to incorrect interpretation of results in experiments investigating potential and actual microbial activity in these low microbial biomass environments. Here, we present an example of how microbial contamination from active layer soil affected analysis of the potentially active microbial community in permafrost soil. We also present the development and use of two tracers: (1) fluorescent plastic microspheres and (2) Pseudomonas putida genetically tagged with Green Fluorescent Protein production to mimic potential microbial contamination of two permafrost cores...

INTRODUCTION AND AIMS: Efforts to reduce excessive alcohol consumption need to take into account drinkers' perceptions of their risk of alcohol-related harm. The aim of the present study was to profile adult Australian drinkers according to their self-identification with various drinker prototypes to determine the extent to which these prototypes are associated with perceived and actual risk of alcohol-related harm. DESIGN AND METHODS: A large web panel provider disseminated an online survey to a national sample of 2168 drinkers aged 18+ years who consumed alcohol at least twice per month...

Increasing identification of transmissions of emerging infectious diseases (EIDs) by blood transfusion raised the question which of these EIDs poses the highest risk to blood safety. For a number of the EIDs that are perceived to be a threat to blood safety, evidence on actual disease or transmission characteristics is lacking, which might render measures against such EIDs disputable. On the other hand, the fact that we call them "emerging" implies almost by definition that we are uncertain about at least some of their characteristics...

The limited capacity for the central nervous system (CNS) to repair itself was first described over 100 years ago by Spanish neuroscientist Ramon Y. Cajal. However, the exact mechanisms underlying this failure in neuronal regeneration remain unclear and, as such, no effective therapeutics yet exist. Numerous studies have attempted to elucidate the biochemical and molecular mechanisms that inhibit neuronal repair with increasing evidence suggesting that several inhibitory factors and repulsive guidance cues active during development actually persist into adulthood and may be contributing to the inhibition of repair...

Necrotizing fasciitis is one of the uncommon presentations of a rapidly spreading subcutaneous tissue infection. Although the actual cause is unclear in many cases, most of them are due to the rapid proliferation of microorganisms. Retroperitoneal necrotizing fasciitis is extremely rare. It is a potentially lethal infection that requires immediate and aggressive surgical care. Early diagnosis is the key to a better prognosis. The possibility of retroperitoneal necrotizing fasciitis should be suspected in patients with symptoms of sepsis that are disproportionate to clinical findings...

Type B trichothecenes, which pose a serious hazard to consumer health, occur worldwide in grains. These mycotoxins are produced mainly by three different trichothecene genotypes/chemotypes: 3ADON (3-acetyldeoxynivalenol), 15ADON (15-acetyldeoxynivalenol) and NIV (nivalenol), named after these three major mycotoxin compounds. Correct identification of these genotypes is elementary for all studies relating to population surveys, fungal ecology and mycotoxicology. Trichothecene producers exhibit enormous strain-dependent chemical diversity, which may result in variation in levels of the genotype's determining toxin and in the production of low to high amounts of atypical compounds...
