The ability of dust in alveoli to produce hydroxyl radicals in phosphate buffer was higher than that in the workplace.Introduction Development within molecular medicine has given us an increased understanding of the pathophysiology of malignant diseases. This understanding has been the key to a development of a number of new effective target-specific drugs, including the PD-1/PD-L1 checkpoint inhibitors.Areas covered This review will focus on the clinical validation and utility of the commercially available IHC PD-L1 expression assays linked to the different PD-1/PD-L1 checkpoint inhibitors indicated for treatment of NSCLC. For the discussion of this subject, mainly data from studies where the PD-1/PD-L1 checkpoint inhibitors have been given as monotherapy will be reported.Expert opinion Although PD-L1 expression is not the perfect biomarker; the different IHC PD-L1 expression assays have had major impact on the clinical development of PD-1/PD-L1 checkpoint inhibitors for treatment of NSCLC. A number of clinical studies in NSCLC have shown that the efficacy of the PD-1/PD-L1 checkpoint inhibitors are positively correlated to the level of PD-L1 expression. Based on studies presented in this review, the recommendation is that monotherapy should mainly be used for treatment of NSCLC patients with a high PD-L1 expression, as defined by the cutoff values for the individual assays linked to the specific PD-1/PD-L1 checkpoint inhibitor.Introduction Trypsinogen and chymotrypsinogen have been used clinically in tissue repair due to their ability to resolve inflammatory symptoms. Recently, novel evidence has supported the anti-tumourigenic potential of a mixture of trypsinogen and chymotrypsinogen.Areas covered First, we analyze the structure of these proteases and the effects of pancreatic proteinases on tissue repair, inflammation and t
