Genome-wide identification and diversity of FAD2, FAD3 and FAE1 genes in terms of biotechnological importance in Camelina species.

Background: False flax, or gold-of-pleasure (Camelina sativa) is an oilseed that has received renewed research interest as a promising vegetable oil feedstock for liquid biofuel production and other non-food uses. This species has also emerged as a model for oilseed biotechnology research that aims to enhance seed oil content and fatty acid quality. To date, a number of genetic engineering and gene editing studies on C.

Rationally designed laterally-condensed-catalysts deliver robust activity and selectivity for ethylene production in acetylene hydrogenation.

Future carbon management strategies require storage in elemental form, achievable through a sequence of CO hydrogenation reactions. Hydrogen is recycled from molecular intermediates by dehydrogenation, and side product acetylene selectively hydrogenated to ethylene. Existing Pd alloy catalysts for gas purification underperform in concentrated feeds, necessitating novel concepts.

Development of vegetative oil sorghum: From lab-to-field.

Biomass crops engineered to accumulate energy-dense triacylglycerols (TAG or 'vegetable oils') in their vegetative tissues have emerged as potential feedstocks to meet the growing demand for renewable diesel and sustainable aviation fuel (SAF). Unlike oil palm and oilseed crops, the current commercial sources of TAG, vegetative tissues, such as leaves and stems, only transiently accumulate TAG. In this report, we used grain (Texas430 or TX430) and sugar-accumulating 'sweet' (Ramada) genotypes of sorghum, a high-yielding, environmentally resilient biomass crop, to accumulate TAG in leaves and stems.

Genome-wide identification and evolution of the tubulin gene family in Camelina sativa.

Background: Tubulins play crucial roles in numerous fundamental processes of plant development. In flowering plants, tubulins are grouped into α-, β- and γ-subfamilies, while α- and β-tubulins possess a large isotype diversity and gene number variations among different species. This circumstance leads to insufficient recognition of orthologous isotypes and significantly complicates extrapolation of obtained experimental results, and brings difficulties for the identification of particular tubulin isotype function.

Autophagy formation, microtubule disorientation, and alteration of ATG8 and tubulin gene expression under simulated microgravity in Arabidopsis thaliana.

Autophagy plays an important role in plant growth and development, pathogen invasion and modulates plant response and adaptation to various abiotic stress stimuli. The biogenesis and trafficking of autophagosomes involve microtubules (MTs) as important actors in the autophagic process. However, initiation of autophagy in plants under microgravity has not been previously studied.

Overcoming genetic paucity of : possibilities for interspecific hybridization conditioned by the genus evolution pathway.

Camelina or false flax () is an emerging oilseed crop and a feedstock for biofuel production. This species is believed to originate from Western Asian and Eastern European regions, where the center of diversity of the genus is located. Cultivated species arose via a series of polyploidization events, serving as bottlenecks narrowing genetic diversity of the species.

Aim: Stroke clot retrieval (SCR) is now considered a standard of care for select stroke patients with proximal large vessel occlusion (LVO) of the anterior circulation. Here we present the experience of regional Taranaki patients transferred by air for SCR and compare this to metropolitan Auckland patients who were transferred by road. The aim is to present and compare process metrics and outcomes between the regional and metropolitan centres.

Dynamics over a Cu-graphite electrode during the gas-phase CO reduction investigated by APXPS.

The electrocatalytic conversion of CO to fuels and chemicals using renewable energy is a key decarbonization technology. From a technological viewpoint, the realization of such process in the gas phase and at room temperature is considered advantageous as it allows one to circumvent the limited CO solubility in liquid electrolytes and CO transport across the electrical double layer. Yet, electrocatalysts' performances reported so far are promising but not satisfactory.

Properties of Bulk In-Pt Intermetallic Compounds in Methanol Steam Reforming.

Heterogeneous catalysts are often complex materials containing different compounds. While this can lead to highly beneficial interfaces, it is difficult to identify the role of single components. In methanol steam reforming (MSR), the interplay between intermetallic compounds, supporting oxides and redox reactions leads to highly active and CO -selective materials.

Learning Instructional Methods and Practices: An Early Career Health Sciences Librarian Perspective.

Formal training or education, in pedagogy in library school or as part of job onboarding process, remains sparse, despite being a required qualification for a significant portion of academic librarian positions. This situation often leaves early career librarians left to piece together their knowledge of effective teaching strategies. This article discusses the experience of an early career librarian in learning pedagogical practices as well as the specific needs of a new discipline.

Cutaneous collagenous vasculopathy: A report of three cases.

Cutaneous collagenous vasculopathy is a rare pauci-inflammatory, superficial, cutaneous vasculopathy characterized by progressive fine-branching telangiectasias clinically, while light microscopically one observes dilated venules and capillaries within the superficial dermis exhibiting excessive Type IV collagen within the vessel wall. We present three cases of collagenous vasculopathy. Two cases were associated with certain autoimmune stigmata, including a positive serologic anti-endothelial cell antibody assay and positive lupus anticoagulant in one, while the third case had positive anti-ribonucleoprotein (RNP) antibodies.

Regulation of dual leucine zipper kinase activity through its interaction with calcineurin.

Hyperglycemia enhancing the intracellular levels of reactive oxygen species (ROS) contributes to dysfunction and progressive loss of beta cells and thereby to diabetes mellitus. The oxidation sensitive calcium/calmodulin dependent phosphatase calcineurin promotes pancreatic beta cell function and survival whereas the dual leucine zipper kinase (DLK) induces apoptosis. Therefore, it was studied whether calcineurin interferes with DLK action.

The Coalescence Behavior of Two-Dimensional Materials Revealed by Multiscale Imaging during Chemical Vapor Deposition Growth.

Wafer-scale monocrystalline two-dimensional (2D) materials can theoretically be grown by seamless coalescence of individual domains into a large single crystal. Here we present a concise study of the coalescence behavior of crystalline 2D films using a combination of complementary methods. Direct observation of overlayer growth from the atomic to the millimeter scale and under model- and industrially relevant growth conditions reveals the influence of the film-substrate interaction on the crystallinity of the 2D film.

[Volvulus of the spiral colon in a pygmy goat buck].

In small ruminants intestinal volvulus is a rare finding and therefore only scarcely mentioned in the literature. The case report summarizes findings and clinical development of a pygmy goat with a volvulus of the spiral colon.

A Peeling Approach for Integrated Manufacturing of Large Monolayer h-BN Crystals.

Hexagonal boron nitride (h-BN) is the only known material aside from graphite with a structure composed of simple, stable, noncorrugated atomically thin layers. While historically used as a lubricant in powder form, h-BN layers have become particularly attractive as an ultimately thin insulator, barrier, or encapsulant. Practically all emerging electronic and photonic device concepts currently rely on h-BN exfoliated from small bulk crystallites, which limits device dimensions and process scalability.

The molecular signature of AML with increased ALDH activity suggests a stem cell origin.

Enrichment of leukemic blasts with a stem cell phenotype correlates with poor survival in acute myeloid leukemia (AML). In this context, measurement of the stem cell marker aldehyde-dehydrogenase (ALDH) activity can distinguish poor prognosis cases with increased fractions of ALDH-positive cells (ALDH-numerous AML) and favorable outcome cases with low percentages (ALDH-rare AML). It has been shown that ALDH-numerous AML favor leukemic engraftment in xenotransplantation assays which suggests increased leukemic stem cell (LSC) potential.

The Chemical Evolution of the LaSrCoO Surface Under SOFC Operating Conditions and Its Implications for Electrochemical Oxygen Exchange Activity.

Owing to its extraordinary high activity for catalysing the oxygen exchange reaction, strontium doped LaCoO (LSC) is one of the most promising materials for solid oxide fuel cell (SOFC) cathodes. However, under SOFC operating conditions this material suffers from performance degradation. This loss of electrochemical activity has been extensively studied in the past and an accumulation of strontium at the LSC surface has been shown to be responsible for most of the degradation effects.

Surface Chemistry of Perovskite-Type Electrodes During High Temperature CO Electrolysis Investigated by Operando Photoelectron Spectroscopy.

Any substantial move of energy sources from fossil fuels to renewable resources requires large scale storage of excess energy, for example, via power to fuel processes. In this respect electrochemical reduction of CO may become very important, since it offers a method of sustainable CO production, which is a crucial prerequisite for synthesis of sustainable fuels. Carbon dioxide reduction in solid oxide electrolysis cells (SOECs) is particularly promising owing to the high operating temperature, which leads to both improved thermodynamics and fast kinetics.

Interfacial charge distributions in carbon-supported palladium catalysts.

Controlling the charge transfer between a semiconducting catalyst carrier and the supported transition metal active phase represents an elite strategy for fine turning the electronic structure of the catalytic centers, hence their activity and selectivity. These phenomena have been theoretically and experimentally elucidated for oxide supports but remain poorly understood for carbons due to their complex nanoscale structure. Here, we combine advanced spectroscopy and microscopy on model Pd/C samples to decouple the electronic and surface chemistry effects on catalytic performance.
