• Not just cars, but living organisms need antifreeze to survive

  If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again. Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter. Without such antifree more

• Ice-free through the winter

  Ants, jellyfish and ground beetles use it to defend themselves and when hunting. How effectively it can protect stinging nettles against predators is something many of us have experienced first hand: the substance in question is formic acid. The acrid and pungent smelling liquid produced by nature a more

• Radio chip and sensor in one

  RFID technology is on the advance. But, up to now radio chips primarily supply data for the identification of products. Researchers have now developed a transponder which measures temperature, pressure and humidity. The chip with sensor function could revolutionize the applications market. »Special more

• Isolation of DNA from Dried Blood Spot Using the High Pure PCR Template Preparation Kit
  

  DNA isolation from anti-coagulated whole blood for subsequent molecular analysis by PCR methods is well-established. In a standard laboratory setting, the blood is shipped in a blood collection vial containing the anticoagulant after phlebotomy. However, it might not always be possible to have blood samples shipped immediately, and for longer storage cooling is required. Freezing anticoagulated blood samples might interfere with the efficiency of DNA isolation afterwards. Thus, the collection and storage of whole blood samples on special filter paper has become more and more popular since it provides a simple and easy method to ship and to store the samples. Evaluation of established DNA isolation kits and procedures is required in order to recommend a protocol for DNA isolation from dried blood spots (DBS). Here, we report the assessment of the High Pure PCR Template Preparation Kit for DNA Isolation from DBS more

• Burn injuries under freezing (labor protection) conditions?
  

  "A little splash of liquid nitrogen hasn't hurt anybody" - this happens to be a widespread opinion in many laboratories. The real dangers connected to cryogenic gases many people had to learn firsthand, unexpected and painful. Skin irritation, cell and tissue damage or severe burn injuries may occur, depending on the type of contact and exposure time. There are less possibilities of medical treatment than for injuries caused by influence of heat more

• Agrisera Western Blot recommendations, troubleshooting and protocol
  

  Each antibody-antigen interaction has unique characteristics. A protocol giving good results for one antibody-antigen pair might found to be unsatisfactory for a second antibody even on the same sample. The interaction of antisera with protein epitopes in Western blot dependens upon a number of factors, all contributing to the final signal/noise ratio. Knowledge and control of those factors allows for modifications and optimization of the procedure. Polyclonal antibodies (serum or IgY-fractions from egg yolk) usually contain a number of different antibodies interacting independently with different epitopes on the target used for immunization. This number is limited for peptide-antigens but if recombinant or native proteins have been used for immunization the signal obtained has to be regarded as cumulative (=caused by several different types of antibodies present in the serum/IgY used) more

• CB1 RECEPTOR SIGNALING REGULATES SOCIAL ANXIETY AND MEMORY

  Abstract The endocannabinoid (eCB) system regulates emotion, stress, memory and cognition through the CB1 receptor. In order to test the role of CB1 signaling in social anxiety and memory, we utilized a genetic knockout (KO) and a pharmacological approach. Specifically, we assessed the effects o more

• Differential scanning calorimetry evaluation of oxidation stability of docosahexaenoic acid in microalgae cells and their extracts

  Summary The aim of this work was to evaluate the oxidative stability of docosahexaenoic acid (DHA) from Aurantiochytrium limacinum SR21 microalgae cells and in their lipidic extract by differential scanning calorimetry (DSC). Besides, freezing was evaluated as a strategy for microalgal DHA long‐ more

• Texture and Pectin Content of Four Frozen Fruits Treated with Calcium

  Abstract In this study, apple, mango, cantaloupe and pineapple cubes were immersed in a 1% calcium chloride solution before being frozen at −40C. The presence of calcium in these fruits did not significantly affect the total pectin content either before or after the freezing and thawing process more

• Belgium Pharmaceuticals and Healthcare Report Q2 2012

  BMI View: Belgium, much like most of the other regional markets, is expected to post negative year-onyear (y-o-y) value growth in its 2012 pharmaceutical sales because of patent expirations and the tightening operating environment. As part of its fiscal austerity programme, the new government is com more
