A V-shaped association between high-density lipoprotein cholesterol levels and poor outcomes in patients after percutaneous coronary intervention.

Background: High density lipoprotein cholesterol (HDL-C) is considered as "good cholesterol". Recent evidence suggests that a high HDL-C level may increase the risk of poor outcomes in some populations.

Purpose: To investigate the association between HDL-C levels and poor outcomes in patients after percutaneous coronary intervention (PCI).

Prognostic value of triglyceride glucose index in population at high cardiovascular disease risk.

Background: Early identification of populations at high cardiovascular disease (CVD) risk and improvement of risk factors can significantly decrease the probability of CVD development and improve outcomes. Insulin resistance (IR) is a CVD risk factor. The triglyceride glucose (TyG) index is a simple and reliable index for evaluating IR.

Hydrogen-bonding network of N,N'-bis[2-(tert-butyldimethylsiloxy)ethyl]ethylenediammonium dichloride.

The title salt, C18H46N2O2Si2(2+)·2Cl(-), has been synthesized by reaction of N,N'-bis(2-hydroxyethyl)ethylenediamine with tert-butyldimethylsilyl chloride. The zigzag backbone dication is located across an inversion centre and the two chloride anions are related by inversion symmetry. The ionic components form a supramolecular two-dimensional network via N-H···Cl hydrogen bonding, which is responsible for the high melting point compared with the oily compound N,N'-bis[2-(tert-butyldimethylsiloxy)ethyl]ethylenediamine.
