 Pacing program can lead to seven-fold reduction in fainting episodesPacing program can lead to seven-fold reduction in fainting episodes
 
Patients with recurrent fainting episodes (syncope) who received a pacemaker delivering a pacing program designed to detect and stop the abnormal heart rhythms that precede syncope had a seven-fold reduction in fainting compared with patients in a placebo pacing group, according to research presented at the American College of Cardiology's 66th Annual Scientific Session.

A minimally invasive treatment for migraine headaches used for adults is also proving to be a safe and effective treatment for children and teenagers, and only takes minutes for a child to feel relief, according to new research presented at the Society of Interventional Radiology's 2017 Annual Scientific Meeting last week.
 
 Enhancing the Reproducibility of Serial Dilutions with Automated Pipetting
 
Enhancing the Reproducibility of Serial Dilutions with Automated PipettingSince pipetting serial dilutions is a time-consuming process and is consequently prone to errors, particularly in 384 well plates, pipetting serial dilutions reproducibly can be very difficult. The human influence impacts most on pipetting results, assuming that pipettes are properly maintained and calibrated. In order to improve reproducibility and accuracy, good pipetting practice should be observed.
 
 
 Using CLARIOstar Microplate Reader to Determine Total Number of Individualized Viable Moss Cells
 
Using CLARIOstar Microplate Reader to Determine Total Number of Individualized Viable Moss CellsA model organism in plant biology is the moss Physcomitrella patens. High rates of homologous recombination, a fast reproduction cycle, and the availability of efficient haploid protonema cell transformation methods make this model organism suitable to serve as an expression system for recombinant proteins.
 
 
 Using the POLARstar® Omega Microplate Reader to Develop High Throughput, Kinetic Protein Unfolding Assays
 
Using the POLARstar® Omega Microplate Reader to Develop High Throughput, Kinetic Protein Unfolding AssaysUnderstanding the kinetics of protein folding that are linked to protein stability is essential to gain knowledge about the structure, energetic and dynamic properties of proteins. Carrying out Ф-value analyses is advantageous, but data collection is laborious for such analyses. Moreover, in most cases, Ф-value analyses are not suitable to high throughput.

 Measurement of Sub-Visible Particles in Parenteral Drugs using AccuSizer 780 SIS Sampler
 
Measurement of Sub-Visible Particles in Parenteral Drugs using AccuSizer 780 SIS SamplerPatients are administered parenteral drugs usually by means of injections, and therefore these drugs must be free of visible particles. To ensure this, the USP Particulate Matter in Injections test is employed for measuring the size and count of sub-visible particles in parenteral drugs, as shown in Figure 1. This test requires counting of particles on a filter by using microscopy and a light obscuration particle counter.
 
 
 Pharmaceutical Applications of Focused Light Obscuration Technology
 
Pharmaceutical Applications of Focused Light Obscuration TechnologySeveral new pharmaceutical preparations, including new vaccines and protein-based drugs, have been commercially available for the past few years. Safety and efficacy of all types of pharmaceutical preparations are largely ensured by Particle Size Analysis. Keeping drug safety in mind, the US Pharmacopeia (USP) contains many particle sizing methods.
 
 
 Linking RNA to autoimmune diseases
 
Linking RNA to autoimmune diseasesWell, the central dogma of biology states that DNA makes RNA and RNA makes proteins. However, there are many different types of RNAs, and only one of them, the messenger RNA (mRNA), gives rise to proteins. Some others don't make proteins at all.
 
 
 Repeatable sample preparation through programmable heated mixers
 
Repeatable sample preparation through programmable heated mixersSample preparation may initially be assumed to be the most basic element of analytical processes in research laboratories. However, the accuracy of measurements achieved during analysis is heavily dependent on the quality of the sample preparation performed. If the substances analyzed do not accurately represent the original samples, the generation of meaningful data is undermined and the study findings are unreliable.
 
 
 Using Electrophoretic Techniques to Measure Zeta Potential of White and Red Blood Cells
 
Using Electrophoretic Techniques to Measure Zeta Potential of White and Red Blood CellsZeta potential is proportional to the charge on the surface of particles and this value can be used to measure the stability of colloidal dispersions. The larger the zeta potential, the stronger the repulsive forces between the particles.

Centrifugal concentrators for biological applicationsIn life science labs around the world the task of concentration of a solute in a solution is commonly achieved using evaporator technology. Such technologies are also widely used in the concentration of pharmaceutical / natural product preparations using an extraction, precipitation and drying of the crude active agent protocol.
 
 
 Study reveals link between endovascular procedures and microbleeding in the brain
 
Study reveals link between endovascular procedures and microbleeding in the brainSmall leakages from blood vessels in the brain, known as microbleeds, increase with age and are associated with cognitive decline. Of 84 older patients undergoing transcatheter aortic valve replacement (TAVR), nearly a quarter developed new microbleeds after their procedure, according to results of a single-center study presented at the American College of Cardiology's 66th Annual Scientific Session.
