Introduction: Statins are the mainstay of lipid-lowering therapies targeted at reducing cardiovascular risk. However, they do not completely obviate risk, not all patients tolerate them, and they are not sufficiently effective in patients with very high plasma levels of low-density lipoprotein-cholesterol (LDL-C) such as those with familial hypercholesterolemia (FH) or patients with elevated plasma levels of lipoprotein(a) [Lp(a)]. Recent advances in the understanding of lipoprotein metabolism have led to the development of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors including evolocumab , which lowers plasma levels of LDL-C by 50 - 75% as monotherapy or in combination with statin therapy.
Areas Covered: We discuss in this review the rationale and background behind the development of evolocumab, and its pharmacodynamics and pharmacokinetics. We then discuss the current state-of-play of relevant clinical trials.
Expert Opinion: The dramatic reduction in plasma levels of LDL-C attributable to evolocumab is anticipated to translate into lower rates of atherosclerotic cardiovascular disease, but this hypothesis remains to be proven. Also to be established are the long-term safety and economic benefits of evolocumab. PCSK9 inhibitors will also probably provide a valuable option for patients with statin intolerance, those with FH and patients with elevated plasma levels of Lp(a).

As an essential micronutrient, phosphorus plays a key role in oceanic biogeochemistry, with its cycling intimately connected to the global carbon cycle and climate change. Authigenic carbonate fluorapatite (CFA) has been suggested to represent a significant phosphorus sink in the deep ocean, but its formation mechanisms in oceanic low-productivity settings remain poorly constrained. Applying X-ray absorption near edge structure, transmission electron microscopy, and laser ablation inductively coupled plasma mass spectrometer analyses, we report a unique mineral assemblage where CFA crystals coat phillipsite in abyssal sediments of the East Mariana Basin and the Philippine Sea.

Background: Hemodialysis may excessively remove valuable solutes. Untargeted metabolomics data from a prior study suggested that ergothioneine was depleted in the plasma of hemodialysis subjects. Ergothioneine is a dietary-derived solute with antioxidant properties.

Background: Acute ischemic stroke treatment typically involves tissue-type plasminogen activator (tPA) or tenecteplase, but about 50% of patients do not achieve successful reperfusion. The causes of tPA resistance, influenced by thrombus composition and timing, are not fully clear. Neutrophil extracellular traps (NETs), associated with poor outcomes and reperfusion resistance, contribute to thrombosis.

Weibel-Palade bodies (WPB) are secretory organelles exclusively found in endothelial cells and among other cargo proteins, contain the hemostatic von-Willebrand factor (VWF). Stimulation of endothelial cells results in exocytosis of WPB and release of their cargo into the vascular lumen, where VWF unfurls into long strings of up to 1000 µm and recruits platelets to sites of vascular injury, thereby mediating a crucial step in the hemostatic response. The function of VWF is strongly correlated to its structure; in order to fulfill its task in the vascular lumen, VWF has to undergo a complex packing/processing after translation into the ER.

Lipopolysaccharides (LPS) are major components of Gram-negative bacteria. LPS not only induce endotoxemia and inflammation, but also contribute to various diseases. In experimental settings, LPS administration serves as a model for acute inflammatory responses.
