Published by BMJ.Lactococcus lactis encounters various environmental challenges, especially acid stress, during its growth. Cell wall can maintain the integrity and shape of the cell under the environmental stress, and D-amino acids play an important role in the cell wall synthesis. Here, by analyzing the effects of 19 diverse D-amino acids on the physiology of L. lactis F44, we found that the exogenously supplied D-methionine and D-phenylalanine could increase the nisin yield by 93.22 % and 101.29 % respectively as wel

We review approaches used to estimate the population health impact of introducing a Modified Risk Tobacco Product (MRTP). Thirteen models are described, some focussing on e-cigarettes, others more general. Most models are cohort-based, comparing results with or without MRTP introduction. They typically start with a population with known smoking habits and then use transition probabilities either to update smoking habits in the "null scenario" or to update joint smoking and MRTP habits in the "alternative scenario". The models vary
