Abstract:
Previous studies have indicated that CD44 isoforms, spliced with variant exons, are heterogeneously glycanated with chondroitin sulphate and heparan sulphate chains. Because such alternative splicing may regulate divergent biological effects of the specific isoforms, we analysed the consequences of this process on the composition and structure of the chondroitin-sulphate chains. Recombinant chimaeras were engineered with and without exons V3-10 or V3,8-10 and expressed as Ig fusion proteins in COS cells. In addition, the chondroitin sulphates of wild-type isoforms were contrasted with those of

Abstract:
SummaryDermatan sulphates have been shown to inhibit thrombus formation and thrombus growth in different experimental models of venous thrombosis. At variance with heparins, they show a remarkably low haemorrhagic potential. On the other hand, very few data are available on the effect of dermatan sulphates on arterial thrombus formation. We evaluated the effects of a low molecular weight (LMW)-dermatan sulphate, a high molecular weight (HMW)-dermatan sulphate and sulo-dexide (a mixture of fast-moving heparin fraction and dermatan sulphate) in comparison with LMW- and HMW-heparin, in a model of

Abstract:
Chondroitin sulphates belong to a group of naturally occurring glycosaminoglycans and play a role in many physiological processes including ageing and the effects of various diseases. Research into chondroitin sulphates has found that the most important analytes are 4- and 6-sulphated disaccharides. We developed an HPLC method for the separation and quantification of underivatized chondroitin/dermatan sulphates—unsaturated disaccharides (4- and 6-sulphated disaccharides). This method is based on the separation of disaccharides by amido as well as amino columns under acidic conditions. These co

Abstract:
Many current structures are characterized by the complexity of architecture (various shapes and bends) and a high concentration of reinforcement which often makes it difficult to use concrete with conventional plasticity. Recent researches have been conducted in order to adopt concrete to these structures. The resulting concrete formulations are characterized by better workability, while remaining stable with mechanical properties and durability. This new type of concrete can fit in place under the influence of gravity, hence the term self compacting concrete “SCC”.

The corrosion products formed in humid air containing SO2 are mainly composed of magnesium sulphites and sulphates, with sulphite-containing corrosion products formed initially while the contribution from sulphates increased with exposure time.

Abstract:
Abstract Microbiologically Influenced Corrosion (MIC) of stainless steel can be caused by the action of Iron Oxidizing Bacteria (IOB) in relatively low chloride waters. One effect of the IOB can be simulated by oxidising ferrous sulphate solution to cause precipitation of a ferric oxide (or hydroxide) deposit, and then drying the precipitated film on to a stainless steel surface. This process may also replicate cooling water treatment of iron-containing waters. In-situ Raman spectroscopy has been used to characterise the deposited film, which is shown to be mainly FeOOH at open-circuit, but is

Abstract:
การใช้ 6% glyceryl guaiacolate ร่วมกับ 0.2% thiopentone sodium ภายหลัง premedication ด้วย atropine sulphate กับ azaperone หรือกับ propionyl promazine เพื่อวางยาสลบสุกร ทำให้เกิดการสลบใกล้เคียงกับ metomidate แต่ analgesic effect ด้อยกว่าการสลบจาก thiopentone sodium โดยเหตุที่ต้องใช้ส่วนผสมนี้ฉีดในปริมาตรที่สูงมาก จึงยังไม่ควรนำมาใช้ในการวางยาสลบสุกร เพื่อการปฏิบัติทางศัลยกรรม หรือเพื่อการใช้ทางคลินิก

Abstract:
The geology of the Montney Formation and the geochemistry of its produced fluids, including nonhydrocarbon gases such as hydrogen sulfide were investigated for both Alberta and BC play areas. Key parameters for understanding a complex petroleum system like the Montney play include changes in thickness, depth of burial, mass balance calculations, timing and magnitudes of paleotemperature exposure, as well as kerogen concentration and types to determine the distribution of hydrocarbon composition, H2S concentrations and CO2 concentrations. Results show that there is first-, second- and third- or

Abstract:
This work aims to improve pipeline segment prioritization for stress corrosion cracking (SCC) excavations. Specifically, it is aimed at optimizing the technical accuracy and the cost of the Association for Materials Protection and Performance (AMPP, formerly NACE) Stress Corrosion Cracking Direct Assessment (SP0204-2015) process by: - evaluating the SCC susceptibility criteria of soil property parameters that were proposed in the first phase of the project (pH, resistivity, sulfide concentration, soil carbon dioxide (CO2) concentration, carbonate concentration, soil oxygen (O2) concentration,

Abstract:
To increase our food security in Västerbotten we will need to become more self-sufficient of both energy, feed and nutrients that are now imported to the region. Biogas production from different waste streams is one solution to this. Biogas is produced using biowaste or sewage sludge as substrate in the major cities Umeå and Skellefteå. Biogas systems offer a range of benefits to society. Biogas production is currently prized for its climate benefits when replacing fossil fuels for the production of heat, electricity and vehicle gas, but at Bothnia Nutrient Recycling we have studied how to use
