https://www.selleckchem.com/products/rxdx-106-cep-40783.html Inflammation is one of major contributors of diabetic osteoporosis. Adipose derived mesenchymal stem cells (AD-MSCs) show great potential to inhibit inflammation. We investigated the anti-osteoporosis role of AD-MSCs-derived exosomes in diabetic osteoporosis and the underlying molecular mechanism. Cellular and animal diabetic osteoporosis models were created through high glucose exposure and streptozotocin injection. AD-MSCs-derived exosomes were isolated and characterized. Pro-inflammatory cytokines and osteoclast markers were determined by ELISA. Bone mineral content and density were detected to evaluate bone loss. qRT-PCR and Western blots were performed to detect the expression of target genes. AD-MSCs-derived exosomes inhibited the secretion of IL-1β and IL-18 in HG treated osteoclasts and restored the bone loss in streptozotocin-induced diabetic osteoporosis rats. Mechanistically, AD-MSCs-derived exosomes suppress NLRP3 inflammasome activation in osteoclasts, and then reduce bone resorption and recover bone loss. AD-MSCs-derived exosomes alleviate diabetic osteoporosis through suppressing NLRP3 inflammasome activation in osteoclasts, which might be a potential cell-free therapeutic approach for diabetes-induced bone loss treatment. Coronavirus disease (COVID-19) has led to significant changes in healthcare systems and its impact on the treatment of cardiovascular conditions, such as ST-elevation myocardial infarction (STEMI), is unknown in countries where the healthcare systems were not saturated, as was the case in Portugal. As such, we aimed to assess the effect on STEMI admissions and outcomes in Portuguese centers. We conducted a single-center, observational, retrospective study including all patients admitted to our hospital due to STEMI between the date of the first SARS-CoV-2 case diagnosed in Portugal and the end of the state of emergency (March and April 2020).
