The multivariate-adjusted OR (95% CI) was estimated to evaluate the association of Lp(a) levels with prevalent MetS (Table 2). In the age- and sex-adjusted model, the highest quartile of Lp(a) level was associated with a lower risk of MetS, when compared with the lowest quartile (OR...
Alkanes are flammable
Structure elucidation of inactive-state GPCRs still mostly relies on X-ray crystallography. The major goal of our work was to create a new GPCR tool that would provide receptor stability and additional soluble surface for crystallization. Towards this ai
Kohn–Sham density functional theory is widely used in chemistry, but no functional can accurately predict the whole range of chemical properties, although recent progress by some doubly hybrid functionals comes close. Here, we optimized a singly hybrid
