Abstract:
Environmental contextRare earth elements (REEs) are strategic metals and emerging contaminants for which plant-based remediation measures are needed. We screened a collection of hardy ferns and identified new accumulator species that preferentially transferred light REEs to their fronds. This study is an important step towards understanding the mechanisms of REE accumulation in plants. AbstractRare earth elements (REEs) include the lanthanides plus yttrium and scandium, and can be split according to their atomic mass into light (LREEs) and heavy REEs (HREEs). The increasing demand for REEs is

Abstract The Bayan Obo deposit in China is endowed with the largest rare earth element (REE) resource in the world. The mechanism resulting in this REE enrichment has been the focus of many studies. Carbonatite is known globally as the most favorable carrier of REE ores. In the Bayan Obo deposit, REE ores are hosted in dolomites (including coarse-grained and fine-grained varieties), and many carbonatite dikes (ferroan, magnesian, and calcic) have been identified. All of the dolomites and carbonatite dikes appear to be broadly coeval and possess similar geochemical characteristics. The Sm-Nd is

During mechanical ventilation the diaphragm experiences an extreme case of muscleunloading. In many cases this results in respiratory muscle dysfunctions making it difficult towean the patient off the ventilator. One component in this dysfunction is the accumulation ofintramyocellular lipids (IMCL) in the diaphragm muscle fibres. Using Oil Red O stainingsand confocal microscopy on rat diaphragm sections we have quantified this process. Theresults show a sudden increase in IMCL contents between 18 and 24 hours.

AbstractErythema is a word derived from the Greek erythros, which describes red color of the skin or mucous membrane. In particular, erythema and redness in scar are important as they are closely related to scar symptoms and tissue maturation, and thus can serve as an indicator for scar prognosis. There is rich information in the literature regarding its clinical manifestation, pathological mechanism, and its relation to inflammation and symptoms of pain and itching as well as the clinical treatment. Scar thickness reflects the accumulation of collagen content and there is no necessary association between scar redness and thickness. This chapter mainly focuses on the overview of scar erythema/redness in the aspects of definition, possible mechanism related to clinical manifestation and symptoms, and finally the therapeutic options.

Abstract:
We conducted biogeochemical investigations of Cd transport and uptake by vegetation over a metamorphic and intrusive terrane in the Fortymile River watershed and Mining District, east-central Alaska. The occurrence of Cd in eolian-dominated sub-arctic soils developed over five major rock units was examined, as well as its relative bioaccumulation in willow. Although the bioaccumulation of Cd by willow (Salix spp.) has been known for some time (Gough 1991), the connection to adverse animal health, under natural (geogenic) conditions, has only recently been demonstrated (Larison et al. 2000, Mykelbust and Pederson 1999). We present Cd data for three soil horizons and the leaf and twig material of Salix glauca L. (grayleaf willow) collected at sites within defined rock units. The cycling of Cd and its bioaccumulation in willow are compared among rock types and soil horizons. Cadmium in study area soils is derived from aeolian dust (loess) and the weathering of the primary bedrock. Plots of rare earth elements (REE, normalized to chondrite abundance’s) in samples of A, B, and C soil horizon soils were similar to REE patterns in regional loess samples and did not correspond to bedrock patterns. Not surprisingly, therefore, we found essentially no difference in the concentration of Cd in soils developed over different lithologic units. In addition, the anthropogenic input (from mining) at sites we sampled was found to be minimal. Cadmium levels in soil are generally higher than that found in the study area rock types (~2ppm)(Day2000). In our acidic soils (pH 4.5-6.0), Cd should be mobile (readily leached), and should tend to form complexes with carbonates, hydroxides, and phosphates. Interestingly, Cd concentrations decrease with increasing soil depth — a trend directly proportional to soil organic matter content. Enrichment factors (EF), a measure of the relative uptake by a plant of an element from its substrate — a sort of “bioavailability” assessment, are presented in Figure 12.2 for Cd in willow leaf material. This procedure normalizes the data, with respect to a geochemical reference element (in this case Ce), for each of the soil horizons developed over the five major rock units.

Abstract:
In this work, the dilution-concentration method proposed in our previous work is optimized to reduce the osmotic damage of red blood cells during the process of removing cryoprotective agents from cryopreserved blood. In the optimization, the dilution region i.e. the tubing length from the dilution point to the concentration point is extended so that the negative accumulation effect of the volume change of red blood cells can be allivated. By doing this, the volume maximum of red blood cells experienced during the removal of cryoprotective agents can be decreased and thereby the osmotic damage

Abstract:
Arteries undergoing atherogenic change show an increase in cholesteryl esterifying activity by acylCoA:cholesterol acetyl-transferase (ACAT) and a progressive accumulation of cholesterol esters within monocyte derived foam cells. The study of these factors, however, is limited by the necessity of obtaining artery tissues for analysis. In this study, an in vivo model (Am J Path 118:134 and 120:391, 1985) which permits the analysis of foam cell development without requiring collection of aortas was examined in more detail.

Its southwest's rugged and mountainous terrain has thick soil, which causes high resistance, poor efficiency, and sometimes even the impossibility to operate agricultural equipment. Using discrete element simulation, a cutting-edge technical technique, it is possible to optimize the agricultural machinery elements that come into contact with the soil in order to reduce drag and increase efficiency. Although there are presently no precise and trustworthy discrete element modeling parameters for red clay, the physical characteristics of red clay in the hilly and mountainous regions of the southw

Abstract:
Genes encoding cone pigments sensitive to middle-to-long wavelengths lie in a head-to-tail tandem array on the X-chromosome. Although two X-encoded genes, one for long-wavelength-sensitive pigments and one for middle-wavelength-sensitive pigments, are sufficient to serve trichromatic color vision, most people have more than two such genes. The arrangement, location, and degree of homology of the pigment genes promote recombination within the tandem arrays. Such recombination events produce pigment-gene complements that differ in the number and sequences of individual genes and in the interrela

A novel detection method for malignant tumour detection through specific accumulation of far-red emitting photosensitisers, has been developed. The set-up, based on He-Ne (633 nm) excitation was tested with phantom malignancies models using photosensitisers on chicken tissue. Intensity vs. depth of tissue measurements as well as photobleaching measurements were performed. Point by point fluorescence imaging indicated that the formation size is not significantly distorted with respect to depth of location.

The approach employed signature-tagged mutagenesis to construct mutants interrupted in individual genes, and the mouse model to identify mutants with attenuated virulence/survival.

It is most unlikely that adjusting to a 1.5 to 2 degree hotter world is possible within the prevailing political and economic norms of our times. In our post-capitalist times we need to modify modern technological market “liberalism” (which has become, actually, techno-feudalism). If we do not modify our present norms, the collapse of the natural means of power and privilege native to our present world order makes it almost inevitable that democratic liberalism will devolve further into a distinctly anti-liberal species of techno-tyranny.

With the objective to increase the S-amino acid content of forage legumes, the goal of this project was to co- express the methionine rich zein genes from corn along with a gene for a key enzyme in methionine biosynthesis, aspartate k
