Developing Product Environmental Footprint Category Rules for Olive Oil

In the context of the Communication “Building the Single Market for Green Products”, the European Commission (EC) recommends a method to measure the environmental performance of products, named the Product Environmental Footprint. The PEF is a multi-criteria measure of the environmental performance of goods and services from a life cycle perspective. Currently, 25 pilot projects test the development of Product Environmental Footprint Category Rules (PEFCRs) for various products. This paper gives an overview of the process of developing the PEFCR for olive oil. An overview of the methods of the PEF screening study that aims at identifying the most relevant environmental impacts, processes and elementary flows are presented. The screening study assesses the impacts of the average olive oil consumed in the European markets.JRC.H.8-Sustainability Assessmen

Ex situ conservation of forest genetic resources in Finland : Evaluation and adaptation of the current strategy

The objectives and methods of conservation of forest genetic resources in Finland are defined in the National Genetic Resources Program for Agriculture, Forestry and Fishery. While dynamic in situ conservation is the preferred type of conservation for most of the economically important tree species, Finland also manages and maintains genetic resources for nine tree species in ex situ conservation units. This document is a revision of the current national ex situ strategy and tries to unravel knowledge and conservation gaps, shows where conservation progress has been made to reach the defined conservation goals, and gives recommendations for the creation of a new action plan. The revision of the current ex situ framework also considers the global context of international treaties, conventions, and strategies aiming at improving genetic conservation in forest trees and monitoring conservation efforts more thoroughly. Due to its versatile applicability, ex situ genetic conservation has the potential to serve conservation needs in a multifunctional way and can make a significant contribution for short-term and long-term protection of forest genetic resources in response to abiotic and biotic threats. Ex situ conservation progress has been made for the highly endangered white elm population in Finland (Ulmus laevis) for which a significant part has been conserved in dynamic and static clonal archives covering the entire natural distribution range in Finland. Conservation progress has also been made for some other noble hardwood species: Oak (Quercus robur), Norway maple (Acer platanoides), and rowan (Sorbus aucuparia). Conservation gaps, on the other hand, do exist for whych elm (Ulmus glabra), linden (Tilia cordata), and in European ash (Fraxinus excelsior). This is mainly because of current biotic threats, which have the potential to drastically reduce the population sizes in these species. In the short-term (3–5 years from now) we recommend conservation plans for European ash, white elm, and whych elm that include the following actions: • Inventory and rescue of resilient European ash clones/families from the 4 existing archives into one dynamic conservation unit. • Development of static ex situ conservation methods (e.g., cryopreservation, seedlots) in European ash for fast rescue into long-term ex situ repositories. • Identification of new conservation units for white elm and wych elm with more favorable site conditions to replace the currently existing units in Paimio. • Achieving a conservation goal in white elm and wych elm of 270 and 425 unrelated individuals, respectively. In the long-term (10–15 years from now) we recommend achieving the following conservation goals for species which are not under immediate threat: • Norway maple (Acer platanoides): 600 unrelated individuals • Linden (Tilia cordata): 1,200 unrelated individuals • Oak (Quercus robur): 400 unrelated individuals • Rowan (Sorbus aucuparia): 400 unrelated individuals • Juniper (Juniperus communis): 400 unrelated individuals • Bird cherry (Prunus padus): 400 unrelated individuals In addition, Luke strongly emphasizes to make use of already existing and novel data resources to improve the genetic monitoring and population genetic analyses of forest genetic resources. Such resources should encompass: • DNA markers & genetic simulation tools • Climate data • Biodiversity databases • Novel sensing technologies for monitoring A detailed implementation plan with budgetary considerations will be prepared by LUKE during 2024 to achieve the conservation targets

Ixodid Tick Vectors of Wild Mammals and Reptiles of Southern India

Background: We aimed to focus on the ixodid ticks parasitizing wild mammals and reptiles from Wayanad Wildlife Sanctuary, Western Ghat, southern India. Methods: The taxonomic identification of ticks collected from wild mammals and reptiles was performed based on the morphology of adults. Results: We revealed eight species of ticks including, Amblyomma integrum, Rhipicephalus (Boophilus) annulatus, Haemaphysalis (Kaiseriana) spinigera, H. (K.) shimoga, H. (K.) bispinosa, H. (Rhipistoma) indica, Rhipicephalus haemaphysaloides and R. sanguineus  s.l. collected from nine species of wild mammals while four tick species Ablyomma kraneveldi, A. pattoni, A. gervaisi and A. javanense parasitizing on four species of reptiles. The highest host rich­ness was shown by H. (K.) bispinosa and R. haemaphysaloides parasitizing six and five different host species, re­spectively.  Reports of R. (B.) annulatus on sambar deer, A. javanense and A. kraneveldi on python as well as A. pat­toni on Indian rat snake are the new host records from this region. Conclusion: Eight species of ticks parasitizing on nine species of wild mammals and four species of parasitizing on four species of reptiles were identified. The highest host richness was shown by H. (K.) bispinosa and R. haemaphy­saloides. H. spinigera as the vector of KFD was also identified in this study

Autoantibodies in a Subgroup of Patients with Linear IgA Disease React with the NC16A Domain of BP1801

Linear IgA disease is an autoimmune subepidermal blistering disease characterized by IgA deposits at the cutaneous basement membrane zone. IgA antibodies from linear IgA disease sera react with antigens of 97 kDa (LABD97) and 120 kDa (LAD-1), both of which appear to be fragments of the extracellular domain of bullous pemphigoid 180 (type XVII collagen). The aim of this study was to determine whether linear IgA disease sera react with the immunodominant region of BP180 (NC16A domain), which is a major target of IgG autoanti-bodies produced by patients with bullous pemphigoid. Indeed, 11 of 50 linear IgA disease sera were found to contain IgA autoantibodies that recognized a recombinant form of NC16A by immunoblotting. The same sera also reacted with NC16A by enzyme-linked immunosorbent assay. An epitope mapping analysis uncovered four linear IgA disease-associated epitopes located within the 45 amino acid N-terminal stretch of NC16A, all of which were previously identified as antigenic sites targeted by bullous pemphigoid autoantibodies. Eight of the linear IgA disease sera that were reactive with NC16A also recognized LAD-1 secreted by the SCC-25 cell line, and five sera recognized BP180 extracted from keratinocytes. Linear IgA disease sera depleted of reactivity to NC16A by immunoadsorption continued to react with both the LAD-1 antigen and BP180 by immunoblotting and with the basement membrane zone by indirect immunofluorescence microscopy. Our results demonstrate that IgA autoantibodies from a subset of linear IgA disease patients react with the same sites on BP180 that are targeted by IgG autoantibodies in bullous pemphigoid

A variant in LIN28B is associated with 2D:4D finger-length ratio, a putative retrospective biomarker of prenatal testosterone exposure

The ratio of the lengths of an individual's second to fourth digit (2D:4D) is commonly used as a noninvasive retrospective biomarker for prenatal androgen exposure. In order to identify the genetic determinants of 2D:4D, we applied a genome-wide association approach to 1507 11-year-old children from the Avon Longitudinal Study of Parents and Children (ALSPAC) in whom 2D:4D ratio had been measured, as well as a sample of 1382 12- to 16-year-olds from the Brisbane Adolescent Twin Study. A meta-analysis of the two scans identified a single variant in the LIN28B gene that was strongly associated with 2D:4D (rs314277: p = 4.1 108) and was subsequently independently replicated in an additional 3659 children from the ALSPAC cohort (p = 1.53 106). The minor allele of the rs314277 variant has previously been linked to increased height and delayed age at menarche, but in our study it was associated with increased 2D:4D in the direction opposite to that of previous reports on the correlation between 2D:4D and age at menarche. Our findings call into question the validity of 2D:4D as a simplistic retrospective biomarker for prenatal testosterone exposure

The Prehistoric Indian Ayurvedic Rice Shashtika Is an Extant Early Domesticate With a Distinct Selection History

Fully domesticated rice is considered to have emerged in India at approximately 2000 B.C., although its origin in India remains a contentious issue. The fast-growing 60-days rice strain described in the Vedic literature (1900–500 B.C.) and termed Shashtika (Sanskrit) or Njavara (Dravidian etymology) in Ayurveda texts including the seminal texts Charaka Samhita and Sushruta Samhita (circa 660–1000 B.C.) is a reliable extant strain among the numerous strains described in the Ayurveda literature. We here report the results of the phylogenetic analysis of Njavara accessions in relation to the cultivars belonging to the known ancestral sub-groups indica, japonica, aromatic, and aus in rice gene pool and the populations of the progenitor species Oryza rufipogon using genetic and gene genealogical methods. Based on neutral microsatellite markers, Njavara produced a major clade, which comprised of minor clades corresponding to the genotypic classes reported in Njavara germplasm, and was distinct from that were produced by the ancestral sub-groups. Further we performed a phylogenetic analysis using the combined sequence of 19 unlinked EST-based sequence tagged site (STS) loci with proven potential in inferring rice phylogeny. In the phylogenetic tree also the Njavara genotypic classes were clearly separated from the ancestral sub-groups. For most loci the genealogical analysis produced a high frequency central haplotype shared among most of the rice samples analyzed in the study including Njavara and a set of O. rufipogon accessions. The haplotypes sharing pattern with the progenitor O. rufipogon suggests a Central India–Southeast Asia origin for Njavara. Results signify that Njavara is genetically distinct in relation to the known ancestral sub-groups in rice. Further, from the phylogenetic features together with the reported morphological characteristics, it is likely that Njavara is an extant early domesticate in Indian rice gene pool, preserved in pure form over millennia by the traditional prudence in on-farm selection using 60-days maturity, because of its medicinal applications

Common variants in the region around Osterix are associated with bone mineral density and growth in childhood

Peak bone mass achieved in adolescence is a determinant of bone mass in later life. In order to identify genetic variants affecting bone mineral density (BMD), we performed a genome-wide association study of BMD and related traits in 1518 children from the Avon Longitudinal Study of Parents and Children (ALSPAC). We compared results with a scan of 134 adults with high or low hip BMD. We identified associations with BMD in an area of chromosome 12 containing the Osterix (SP7) locus, a transcription factor responsible for regulating osteoblast differentiation (ALSPAC: P = 5.8 × 10−4; Australia: P = 3.7 × 10−4). This region has previously shown evidence of association with adult hip and lumbar spine BMD in an Icelandic population, as well as nominal association in a UK population. A meta-analysis of these existing studies revealed strong association between SNPs in the Osterix region and adult lumbar spine BMD (P = 9.9 × 10−11). In light of these findings, we genotyped a further 3692 individuals from ALSPAC who had whole body BMD and confirmed the association in children as well (P = 5.4 × 10−5). Moreover, all SNPs were related to height in ALSPAC children, but not weight or body mass index, and when height was included as a covariate in the regression equation, the association with total body BMD was attenuated. We conclude that genetic variants in the region of Osterix are associated with BMD in children and adults probably through primary effects on growth

Surface Modification of Acetaminophen Particles by Atomic Layer Deposition

Organic solid pharmaceutical powders are used for the preparation of various drug dosage forms. Primary particles in powder form undergo several processing steps first in pharmaceutical formulations followed by pharmaceutical manufacturing to final dosage form of a drug. These unit operations involve both handling of powders in aqueous or solvent solutions and drying. There will be a probable rise for a demand for the different unit operations in the requirements of protecting the active pharmaceutical ingredient or challenges in powder handling. Besides pharmaceutical manufacturing, there are many biological interfaces where control of surface characteristics of pharmaceutical powders can improve the therapeutic response and bioavailability. In this work, we have modified acetaminophen particles with atomic layer deposition (ALD) by conformal nanometer scale coatings in a one-step coating process. According to the results, ALD comprising common chemistries for Al2O3, TiO2 and ZnO is shown to be a promising coating method for solid pharmaceutical powders. Acetaminophen does not undergo degradation during the ALD coating and maintains its stable polymorphic structure. The nanometer scale ALD coating can sustain the drug release. ALD oxide coated acetaminophen particles show different cytocompatibility assessed in in vitro intestinal Caco-2 cells.Peer reviewe

Integrative analysis of gene expression, DNA methylation, physiological traits, and genetic variation in human skeletal muscle

We integrate comeasured gene expression and DNA methylation (DNAme) in 265 human skeletal muscle biopsies from the FUSION study with >7 million genetic variants and eight physiological traits: height, waist, weight, waist-hip ratio, body mass index, fasting serum insulin, fasting plasma glucose, and type 2 diabetes. We find hundreds of genes and DNAme sites associated with fasting insulin, waist, and body mass index, as well as thousands of DNAme sites associated with gene expression (eQTM). We find that controlling for heterogeneity in tissue/muscle fiber type reduces the number of physiological trait associations, and that long-range eQTMs (>1 Mb) are reduced when controlling for tissue/muscle fiber type or latent factors. We map genetic regulators (quantitative trait loci; QTLs) of expression (eQTLs) and DNAme (mQTLs). Using Mendelian randomization (MR) and mediation techniques, we leverage these genetic maps to predict 213 causal relationships between expression and DNAme, approximately two-thirds of which predict methylation to causally influence expression. We use MR to integrate FUSION mQTLs, FUSION eQTLs, and GTEx eQTLs for 48 tissues with genetic associations for 534 diseases and quantitative traits. We identify hundreds of genes and thousands of DNAme sites that may drive the reported disease/quantitative trait genetic associations. We identify 300 gene expression MR associations that are present in both FUSION and GTEx skeletal muscle and that show stronger evidence of MR association in skeletal muscle than other tissues, which may partially reflect differences in power across tissues. As one example, we find that increased RXRA muscle expression may decrease lean tissue mass.Peer reviewe
