Women with HIV may benefit from a vaccine for human papillomavirus (HPV), despite having already been exposed to HPV, a study finds. Although many may have been exposed to less serious forms of HPV, more than 45 percent of sexually active young women who have acquired HIV appear never to have been exposed to the most common high-risk forms of HPV, according to the study from a National Institutes of Health research network.

Scientists Help Identify A Missing Link In Taste Perception
Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception.

Improving DNA Removal from Bioprocess Purification Processes
Many new biological drug products produced using recombinant DNA technology, such as monoclonal antibodies, are produced in cell culture. Because therapeutic proteins such as monoclonal antibodies are produced in cell culture, impurities can result from the host cells, or cell substrates. By 3M Purification Inc.

Microbial Fermentation In Single-Use Xcellerex™ XDR-50 MO Fermentor SystemThis application note describes the performance of a single-use Xcellerex XDR-50 bioreactor system when used in cultivations of E. coli and of modified Pseudomonas fluorecsens (P. fluorescens) producing a monoclonal antibody (MAb). Both the achieved microbe densities and product yield were shown to be consistent with the performance of conventional stainless steel systems.

The Challenge of Measuring Total Organic Carbon In Modern Pharmaceutical Water Systems
Total Organic Carbon (TOC) is one of the quality attributes defined in the European and USA pharmacopoeias for pharmaceutical waters. Modern water treatment systems can deliver such high purity water that TOC levels can be consistently close to zero and very difficult to measure with any accuracy. This paper discusses some of the challenges when using TOC analysers to demonstrate pharmacopoeial TOC level compliance for modern water systems in the light of the ICH Q2 document from the International Conference on Harmonisation.
