    Description: Inflammation is an important step in the early phase of tissue regeneration around an implanted metallic orthopaedic device. However, prolonged inflammation, which can be induced by metallic corrosion products, can lead to aseptic loosening and implant failure. Cells in peri-implant tissue as well as metal corrosion can induce reactive oxygen species (ROS) formation, thus contributing to an oxidative microenvironment around an implant. Understanding cellular reactions to implant-induced oxidative stress and inflammatory activation is important to help prevent an adverse response to metallic materials. In an earlier study we have shown that endothelial cells grown on Ti6Al4V alloy are subjected to oxidative stress. Since endothelial cells play a critical role in inflammation, in this study we examined the role of oxidative stress in their response to pro-inflammatory activation. Therefore, we stimulated endothelial cells in contact with Ti6Al4V with tumour necrosis factor-α (TNF-α) and monitored the expression of inflammation-associated molecules, such as E-selectin, intercellular adhesion molecule-1 (ICAM-1) and interleukin-8 (IL-8). The induction of these proteins was lower in endothelial cells on Ti6Al4V compared to control tissue culture conditions. There was, however, a discrepancy in pro-inflammatory activation at protein compared to mRNA level in the cells on Ti6Al4V. To examine the role of oxidative stress in this response we utilized different ROS scavengers and showed that ROS depletion improved cellular response to TNF-α on Ti6Al4V. These results could contribute to developing strategies to improve tissue response to metal implants.

    Description: Obituaries do not only announce the death of a significant other but also provide insights into how a society deals with death according to the norms governing the rituals of individuals within that society. This study aimed at investigating possible differences between German and Dutch obituaries, specifically in terms of visual and textual elements, information about the deceased, and funeral ceremony-related information. Data used to address the research questions were the contents of 240 German and 240 Dutch obituaries published in 10 different newspapers (6 in Germany, 4 in the Netherlands). Results of this study show that statistically significant differences between German and Dutch obituaries exist. While German obituaries use illustrations more than Dutch ones, Dutch obituaries provide more information, in general, than their German counterparts. The types of deceased-related information on German and Dutch obituaries also vary significantly. Moreover, Dutch obituaries provide more funeral ceremony-related information than German obituaries.

    Description: Grasslands are a major part of the global ecosystem, and make a significant contribution to food security through providing part of the feed requirement of ruminants for meat and milk production. Breeding has the potential to improve the characteristics of grassland species to withstand adverse environmental conditions and to increase their overall growth and vigour. Grasslands consist of a mixture of several species that are adapted to specific ecosystems, and the breeding effort is directed mainly towards the major species, mostly for enhanced agronomic performance. It is only in the past decade that major efforts have been made in the field of ‘omics’ to unravel the underlying causes of the responses of forage species to environmental stimuli and to develop tools for selection in breeding programmes. This Highlight section of Annals of Botany comprises eight papers that examine various aspects of breeding for improvement in forage and grass species.

    Description: Also known as the privacy paradox, recent research on online behavior has revealed discrepancies between user attitude and their actual behavior. More specifically: While users claim to be very concerned about their privacy, they nevertheless undertake very little to protect their personal data. This systematic literature review explores the different theories on the phenomenon known as the privacy paradox. Drawing on a sample of 32 full papers that explore 35 theories in total, we determined that a user’s decision-making process as it pertains to the willingness to divulge privacy information is generally driven by two considerations: (1) risk-benefit evaluation and (2) risk assessment deemed be none or negligible. By classifying in accordance with these two considerations, we have compiled a comprehensive model using all the variables mentioned in the discussed papers. The overall findings of the systematic literature review will investigate the nature of decision-making (rational vs. irrational) and the context in which the privacy paradox takes place, with a special focus on mobile computing. Furthermore, possible solutions and research limitation issues will be discussed.

    Description: This paper highlights two groups of Jews, Palestinian prisoners of war and Jewish penitentiary prisoners, who remained largely "invisible" within the Nazi camp system as, unlike Jewish camp inmates, they were not visibly marked by the yellow star and German authorities kept their Jewish identities secret. In the industrial camp complex of Blechhammer in Upper Silesia, Palestinian POWs, Jewish penitentiary prisoners and inmates of the forced labour camp for Jews coexisted for over a year, while three different sets of legal frameworks determined their status and respective treatment: the Geneva Conventions, the Prison Regulations for Poles and Jews and Nazi anti-Jewish legislation. Compared to the "visible" inmates, the two "invisible" groups had significantly higher survival rates, partly the result of their (temporary) protection from the regime's annihilationist policy. While the workforce of all three was exhaustively exploited and food was limited, POWs and penitentiary prisoners received better medical attention and, most importantly, did not fall victim to selections for the Auschwitz death camp. However, it also became evident that their "invisibility", the fact that they could not be distinguished from non-Jews, contributed to their survival

    Description: Miscanthus and Saccharum are closely related perennial C 4 grasses. Miscanthus has recently attracted interest as a non-food crop for energy and fibre production. However, molecular genetic tools for the selection of new Miscanthus genotypes and study of its genetic resources are limited. We have identified six chloroplast (plastid) marker loci,containing both microsatellites (cpSSRs) and single nucleotide polymorphisms (SNPs) and developed primers to amplify and sequence these regions. The primers were designed using the complete chloroplast genome sequence of sugarcane and were tested on a collection of 164 Miscanthus genotypes and 14 related species of the subfamily Panicoideae. The cpSSR markers were highly polymorphic, with the number of alleles ranging from 10 to 16 per locus. Within the six cpSSR marker loci, the hybrid M. × giganteus exhibits virtually no cpDNA variation compared with its putative parents M. sinensis and M. sacchariflorus . These SNP markers enable the differentiation of most Miscanthus species and detect infraspecific variation suitable for defining cytoplasmic genepools of Miscanthus for breeding purposes.

    Description: Natural sodium borate minerals from non-marine evaporite sequences are used for world production of sodium perborate, an industrially manufactured bleaching agent added to a variety of detergent formulations and cleaning products. During end use, water-soluble boron compounds are discharged with domestic aqueous effluents into sewage treatment plants, where little or no boron is removed and, hence, the anthropogenic boron load is almost entirely released into the aquatic environment. Natural sodium borate minerals are characterized by a rather narrow range in boron isotopic composition within the large natural variations, such that an isotopic approach may be used to decipher an anthropogenic boron source (mainly from industrial perborate, the dominant use of mined boron) in a given natural aquatic system that is characterized by a distinctive local background signature. This paper presents new boron isotope data for a series of industrial sodium perborate monohydrate and tetrahydrate products. super(11)B/ super(10)B isotopic ratios were measured by NTIMS (Negative Thermal Ionization Mass Spectrometry) with an analytical uncertainty of plus or minus 0.5ppt (2 sigma sub(mean)). Boron isotope values of sodium perborate monohydrate and tetrahydrate products, reported as delta super(11)B values (in per mille) relative to a mean super(11)B/ super(10)B ratio of 4.00125 measured for the NIST SRM-951 boric acid standard ( delta super(11)B = {[( super(11)B / super(10)B) sub(Sample)/( super(11)B/ super(10)B) sub(Standard)] - 1} x 10 super(3)), show variations from -3.9 to +0.9ppt and -4.8 to + 0.5ppt. respectively, which are within the delta super(11)B range of natural sodium borate minerals. The application of this innovative stable isotope tracer technique for monitoring pollution of natural aquatic systems is discussed in the framework of two case studies which demonstrate the usefulness of boron isotopes for constraining distinct solute sources (anthropogenic vs natural) in groundwater.
