Read MoreHayfever: time we moved exams to the winter?Aug 2, 2010
Crucial exams take place during adolescence in most societies, which can have a major impact on an individual's career trajectory. In a Guest Editorial appearing in the August issue of Expert Review of Respiratory Medicine, a team of UK experts review the evidence of the disease burden associated with hayfever and summarize recent evidence suggesting that poorly controlled hayfever can adversely impact on exam performance
Read MoreHaiti: might the earthquake worsen TB rates? Jul 28, 2010
Prior to the earthquake of January 12th 2010, Haiti had experienced the highest TB notification rate in the Latin America and Caribbean region. In a forthcoming editorial in Expert Review of Respiratory Medicine, Kevin Schwartzman and colleagues from the McGill University Health Centre (Montreal, Canada) discuss whether the devastation of Haiti six months ago will lead to an unavoidable increase in the incidence of TB.

Read MoreThe Eppendorf Research plus pipette May 17, 2010
In today's research environment, attention on pipettes no longer focuses exclusively on precision and accuracy; instead, user-friendly operating features, which reduce strain during pipetting, have moved into the foreground. Therefore, ergonomics plays an important role for the user. Primarily mentioned aspects are the weight of the pipette and the forces required during use. Included in the handling force are, among others, the force required for attachment and securing as well as ejection of the pipette tip. The new mechanical pipettes of the pipette family Eppendorf Research plus have demonstrated optimal performance in all those areas.
Read MoreUser Report on epMotion from the research laboratory of the Institute of Pathology at the Technical University of MunichMay 17, 2010
After our work group in the department of pathology in the University Hospital rechts der Isar had established a method for the extraction of proteins from fixed materials embedded in paraffin, we wanted to analyze these samples on a antibody specificity, and to avoid entering the saturation range during quantification, serial dilutions need to be spotted onto the slide. These must be prepared in 96-well and/or even 384-well plates.
Read MoreReducing PCR reaction times by using faster ramp rates, modifying programs and changing the reaction mixMay 17, 2010
In the modern laboratory, speed is often of the essence and any process capable of saving valuable research time is an advantage. One recent advance in this direction is the development of fast PCR protocols which include both specialised PCR reagents and modified thermal cycling steps. The Techne TC-PLUS thermal cycler gives the user all the features required to make best use of these new methodologies by offering flexible programming and rapid block ramp rates of up to 5ºC/s.
Read MorePerforming Cell Growth Curve Experiments with different Substances on the Eppendorf epMotion 5075 LHMay 17, 2010
In the present Application Note we make use of the liquid handling system epMotion® 5075 LH to analyze simultaneously the influence of seven different concentrations of three substances dissolved in three different solvents on the growth of the fibroblast cell line NIH/3T3. Three independent experiments were performed and each experiment is divided into 5 steps: Cell seeding, Cell treatment, Culture media change, Fixation and Sulforhodamin B staining and measurement.

Read MoreTracking Down Fake CashmereFeb 28, 2010
New application note from Retsch GmbH
Due to the fact that only a very small amount can be won from each animal, cashmere wool is an expensive resource for the textile industry which makes it susceptible to falsifications. Instead of cashmere, the cheaper sheep wool is used and the product is then declared as genuine cashmere. Or products only contain a small amount of cashmere while the rest is wool from other animals which is processed without declaration.
The research laboratory of Shell Global Solutions in Amsterdam has recently been equipped with state-of-the-art particle measurement systems for catalyst research. By using two instruments from Retsch Technology the Shell researchers are now able to determine particle sizes in a range from 10 nanometers to 30 millimeters.

Read MoreDetection of Mycotoxins in NutsDec 21, 2009
Mykotoxins are natural metabolism products of molds which have a toxic effect on humans and animals. Just like micro-organisms which generate antibiotics, molds which generate mycotoxins have spread all over the world. Aflatoxins are the most toxic form of mycotoxins. Some types of food show an increased risk of aflatoxin release due to fungal infestation: dried fruit, spices, nuts (peanuts, hazelnuts, pistachios) and grain (wheat, corn).
In many pilot-plant or production facilities temperature control systems are like a wallflower at the junior high school dance – they are not the most technical, expensive or exciting equipment in the room and are easily overlooked. But, when the most popular person in the class asks the wallflower to dance...
Read MoreParticle sizing with static laser scatteringDec 11, 2009
When determining particle sizes a wide variety of techniques are used in which sieving may be the most popular. Sieving is a relatively simple technique, despite the fact that of course different instrumental approaches can be used. The main advantages of sieving are the low price of the instrumentation and the fact that different fractions of the original sample can be prepared for further use.
