Development and Clinical Application of an Enzyme-Linked Immunosorbent Assay for Oxidized High-Density Lipoprotein.
CONCLUSION: We have established a novel sandwich ELISA for Ox-HDL, which might be a useful and easy strategy to evaluate HDL functionality, although the comparison study between this Ox-HDL ELISA and the assay of HDL cholesterol efflux capacity remains to be done. Our results indicated that probucol treatment may be associated with lower Ox-HDL levels. PMID: 33028763 [PubMed - as supplied by publisher]
AbstractAbstractCancer patients with acute coronary syndrome (ACS) have significantly greater mortality compared with non-cancer patients. This risk is partly directly attributable to the malignancy; however these patients are frequently undertreated with respect to guideline recommended treatments for ACS due to higher bleeding risks from anemia and thrombocytopenia. Due to exclusion from large clinical trials, there is a paucity of data regarding how to best treat these complex and high-risk patients.Purpose of ReviewTo review the literature and identify risk factors among cancer patients associated with poor outcomes, p...
CONCLUSIONS: Our data demonstrate that UPR is necessary and sufficient to drive phenotypic switching of SMCs to cells that resemble modulated SMCs found in atherosclerotic plaques. Preventing a UPR in hyperlipidemic mice diminishes atherosclerotic burden, and our data suggest that preventing SMC transition to dedifferentiated cells expressing macrophage and fibroblast markers contributes to this decreased plaque burden.

CONCLUSION: The results suggest that lipid accumulation induced macrophage recruitment in swine livers, and that the number of M2-like macrophages increased at the early stage of NAFLD, while the number of M1-like macrophages increased at the late stage of NAFLD, resulting in a liver condition like non-alcoholic steatohepatitis. We provide evidence of the phenotypic changes that occur in macrophages during the development of NAFLD that has never been reported before using µMPs.

CONCLUSIONS: Modulation of the quantity and quality of ApoM might explain, at least in part, the impaired functions of HDL in subjects with diabetes mellitus. ApoM might be a useful target for laboratory testing and/or the treatment of diabetes mellitus. PMID: 32999208 [PubMed - as supplied by publisher]
CONCLUSIONS: Our study demonstrates the development of spontaneous atherosclerotic lesions in aged male and female LCAT-/- hamsters with higher plasma oxidative lipid levels independent of plasma total cholesterol levels, further confirming the antiatherosclerotic role of LCAT.

CONCLUSIONS: The neutrality of 18:0 on plasma LDL-cholesterol concentrations is not attributable to a single factor. Compared with 18:1, 18:0 had higher plasma area under the curve because of lower clearance and oxidation rates, underwent both a direct and a multistage conversion to 18:1, and was preferentially incorporated into cholesteryl esters and triglycerides.

Conclusions: PCSK9 in plasma directly enhances platelet activation and in vivo thrombosis, as well as MI expansion post-MI, by binding to platelet CD36 and thus activating the downstream signaling pathways. PCSK9 inhibitors or aspirin abolish the enhancing effects of PCSK9, supporting the use of aspirin in patients with high plasma PCSK9 levels in addition to PCSK9 inhibitors to prevent thrombotic complications.

Microvascular and macrovascular thrombotic events are among the hallmarks of coronavirus disease 2019 (COVID-19). Furthermore, the exuberant immune response is considered an important driver of pulmonary and extrapulmonary manifestations of COVID-19. The optimal management strategy to prevent thrombosis in critically-ill patients with COVID-19 remains unknown.
AbstractAntiplatelet agents and statin therapies are widely used in patients with known cardiovascular disease. Plaque rupture (PR) and plaque erosion (PE) are the most frequent underlying mechanisms of acute coronary syndromes (ACS). The conditions and medications that are associated with ST-segment elevation myocardial infarction (STEMI) following PR or PE have not been systematically studied. A total of 838 ACS patients (494 with STEMI, 344 with NSTE-ACS) who were diagnosed with PR or PE by optical coherence tomography were included. The patients were categorized into two groups based on underlying pathology, and the ba...
CONCLUSIONS: Our findings suggest that prestroke statin use was associated with good leptomeningeal collaterals and clinical outcomes in acute ischemic stroke (AIS) patients presenting with occlusion of the middle cerebral artery. However, clinical studies should be conducted to verify this claim. PMID: 32925118 [PubMed - as supplied by publisher]
