geopolymer cement (inorganic polymeric binder) based on natural pozzolan are investigated. SiOof activator and total molar ratios of Nacomposition exhibiting the highest 28-day compressive strength. Mixtures exhibiting the highest compressive strength were studied for their molecular structure using laboratory technique of Fourier transform infrared spectroscopy.Results obtained confirm that ch...

BACKGROUND New technologies for molecular analysis are increasing our ability to diagnose cancer. METHODS Several molecular analysis technologies are reviewed and their use in the clinical laboratory is discussed. RESULTS Select key technologies, including polymerase chain reaction and next-generation sequencing, are helping transform our ability to analyze cancer specimens. As these techno...

What is it famous for? The MRC (Medical Research Council) Laboratory of Molecular Biology, or LMB, is the 'birthplace of molecular biology'. From humble beginnings in a temporary hut in Cambridge, UK, an extraordinarily talented group of scientists produced a series of breakthroughs, starting with Watson and Crick's Nobel prize-winning discovery of the double helix.

SUMMARY VIRTLAB is a self-training program based on PBL (Problem-Based-Learning Pathway) built to simulate a molecular biology laboratory. It has been designed to stimulate students in the biological sciences to analyse and solve molecular biology problems using standard laboratory techniques (e.g. restriction enzyme digestions, analytical and preparative agarose gels, DNA cloning and sequencin...
