The reactive triazine dye, Cibacron Blue F3G-A, has been covalently attached to microparticulate porous silica and used for the resolution of a number of complementary proteins by high-performance liquid affinity chromatography (HPLAC). Cibacron Blue F3G-A was converted to its 6-aminohexyl derivative by reaction with 1,6-diaminohexane and coupled to γ-glycidoxypropyltrimethoxysilane-activated poro
Three methods were developed for preparing alginate gels containing cells that are stable in phosphate containing media. In Method I preformed alginate beads containing entrapped cells were treated with polyethyl eneimine followed by glutaraldehyde. In Method II alginate sol was treated with a carbodiimide and N-hydroxysuccinimide (to form active esters), mixed with cells and extruded into calcium
I denna master class går forskarna igenom huvudpoängerna i den pupulärvetenskapliga rapporten Framtidens möten.Projektet handlar om nya modeller för affärer, interaktion och kommunikation inom mötesindustrin. Forskarna har undersökt hur pandemin påverkat mötesindustrin och om krisen fört med sig nya möjligheter. De har också studerat hur gäster i fysiska, hybrida och digitala möten och konferenser
Spores of Curvularia lunata were immobilized in polyacrylamide granules and in calcium alginate beads (2–3 mm in diam.). Germination of the spores, initiated by the addition of nutrients, resulted in an even distribution of mycelium throughout the beads after 48 h. Such beads were used for the conversion of cortexolone to cortisol by steroid-11β-hydroxylation. In order to improve the steroid trans
An enzyme-coenzyme complex was immobilized on the surface of a glassy carbon electrode and investigated with cyclic voltammetry in ethanol-containing buffers. The complex consists of an Liver Alcohol Dehydrogenase molecule to which an NAD-analogue is covalently attached via its straight six-carbon, spacer. One cycle was observed but repeated recycling could not be carried out. presumably due to ca
Whole cells of Arthrobacter simplex were immobilized in a living state in calcium alginate gel. The bacteria showed steroid-Δ1-dehydrogenase activity and the production of prednisolone from cortisol was investigated. The Δ1-dehydrogenase activity of the immobilized cells could be increased about ten-fold by incubation in nutrient media (e.g., containing 0.5% peptone abd 0.2% glucose). The reason f
The present facsimile of The Rudiments or Principles of the German flute (1729)—now republished for the first time since 1729—is a separate supplement to the comparativestudy Les Traditions en Mouvement Principes de la Flute Traversiere ou Flute d’Allemagne (1707) by Jacques Hotteterre Le Romain and The Rudiments or Principles of the German flute (1729) the first English translation of Hotteterre’
Saccharomyces cerevisiae was immobilized in calcium alginate gel together with varying concentrations of iron oxide, in the form of magnetite or a colloidal ferrite suspension, Ferrofluid™. Inclusion of magnetic material apparently had no adverse effect on the yeast cells as judged from their fermentation capacity, their operational stability as well as their ability to propagatein situ in the pre
This paper describes the preparation of a bifunctional NAD compound (Bis-NAD) and its properties as a complexing/precipitating agent for the tetrameric enzyme lactate dehydrogenase (LDH).
To plan, design and build with diversity in mind is a complex process. While goals such as inclusion, participation and social sustainability may be present in the vision for a future product, service or environment, studies show that the initial vision isn’t always realized in the end result. There are still far too many products, services and environments that are hard to access or use for parts
Background: Informal caregivers may experience high levels burden. Prior to COVID-19, loneliness and social isolation, and especially the discordance between them, were recognized for rapid aging-related cognitive decline. The COVID-19 has significantly increased social isolation and loneliness in caregivers. Thus, we aimed to explore the variables that were associated with higher care burden amon
Large-scale gene sequencing studies for complex traits have the potential to identify causal genes with therapeutic implications. We performed gene-based association testing of blood lipid levels with rare (minor allele frequency < 1%) predicted damaging coding variation by using sequence data from >170,000 individuals from multiple ancestries: 97,493 European, 30,025 South Asian, 16,507 African,
Background: Neurofibrillary tangle pathology is thought to drive neurodegeneration in beta-amyloid positive (A+) cognitively normal (CN) individuals, i.e., preclinical Alzheimer’s disease (AD).However, in beta-amyloid negative (A-) CN, the contribution of tau pathology [primary age-related tauopathy (PART)] to neurodegeneration remains uncertain. We investigate the correlation between tau burden m
Background: The COVID-19 pandemic has renewed attention to the conflicting demands placed on caregivers worldwide. Nowhere is this more evident than in South Asia, where cultural norms and a scarcity of long-term care facilities have made the home the locus of caregiving for individuals with brain health conditions and disabilities. A hidden cost of this informal arrangement is the burden experien
BACKGROUND: The relation between blood pressure and kidney cancer risk is well established but complex and different study designs have reported discrepant findings on the relative importance of diastolic blood pressure (DBP) and systolic blood pressure (SBP). In this study, we sought to describe the temporal relation between diastolic and SBP with renal cell carcinoma (RCC) risk in detail.METHODS
