In an interesting Turkish retrospective study, conducted between 2012 and 2015, involving 1510 adults, Kekilli et al.[1] tested triple therapy (lansoprazole 30 mg b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.), bismuth group C (lansoprazole, clarithromycin, amoxicillin, and bismuth subsalicylate 524 mg b.i.d.), and bismuth group M (lansoprazole, amoxicillin, metronidazole 500...

Most strains of the yeast Saccharomyces cerevisiae contain many copies of a 2-microm plasmid, a selfish autonomously replicating DNA that relies on two different mechanisms to ensure its survival. One of these mechanisms involves the high fidelity segregation of the plasmids to daughter cells during cell division, a property that is starkly reminiscent of centromeres. A new study reported in th...

Glycoscience—the study of the complex carbohydrates on the surface of proteins and lipids—has long been the neglected stepchild of molecular biology. Although genomics, proteomics and now systems biology have become hot topics of biomedical research, attracting both researchers and funding, glycoscience has played a rather minor role. Once of little interest to understanding biology on a larger...
