ABSTRACT Staphylococcus aureus is an opportunistic pathogen that employs an array of different virulence factors to evade the immune system.The bi-component pore-forming leukocidins are of particular importance for their ability to target and kill phagocytes.The operon of two of these toxins, lukED and lukSF-PV, are repressed by two proteins, SarS
The concentrically braced system is one of the most common lateral load bearing systems among steel structures.These systems have remarkable lateral stiffness and strength, but their compressive Fitness Toys buckling prevents them from being ductile and absorbing optimal energy.In this study to solve this problem, by using numerical and experimenta
Human rhinoviruses (HRVs) are associated with acute exacerbations in patients with chronic obstructive pulmonary disease (COPD) and asthma, which are accompanied by mucus hypersecretion.Whereas, various studies have shown that HRVs increase epithelial mucin production and thus may directly contribute to mucus hypersecretion.The effects of drugs use
Introduction: Lactate has gained increasing attention as a platform chemical, particularly for the production of the bioplastic poly-lactic acid (PLA).While current microbial lactate production processes primarily rely on the use of sugars as carbon sources, it is possible to envision a future where lactate can be produced from sustainable, non-foo
