Identification of Diagnostic Magnetic Resonance Imaging Findings in 47 Shoulders with Subcoracoid Impingement Syndrome by Comparison with 100 Normal Shoulders.

BACKGROUND The aim of this study was to identify the diagnostic magnetic resonance imaging (MRI) findings in 47 shoulders with subcoracoid impingement syndrome by comparison with 100 normal shoulders. MATERIAL AND METHODS The subcoracoid impingement syndrome group consisted of 47 shoulders with subcoracoid impingement syndrome and the normal group consisted of 100 normal shoulders. The MRI parameters - coracoids-humeral distance (CHD), coracoid index (CI), height of the lesser tuberosity (HLT), coracoid obliquity (CO), coracoglenoid angle (CGA), coracohumeral angle (CHA), width of the subscapular tendon (WST), and contact distance between subscapular tendon and coracoid process (CD) - were compared between the subcoracoid impingement syndrome group and the normal group.

Discovering Peptide Inhibitors of Human Squalene Synthase Through Screening the Phage-Displayed Cyclic Peptide c7c Library.

Many drugs for the treatment of hypercholesterolemia are targeting the enzymes involved in human cholesterol biosynthesis pathway. Squalene synthase, the rate-limiting enzyme located at the downstream of cholesterol synthesis pathway, has become a better candidate to develop next-generation hypocholesterolemia drugs. In the present study, we cloned and expressed the recombinant human squalene synthase (hSQS) as the lure to isolate potential peptide inhibitors from screening the conformation-constrained phage-displayed cyclic peptide c7c library.

Exploration of Peptide Inhibitors of Human Squalene Synthase through Molecular Modeling and Phage Display Technique.

Many studies have demonstrated the role of elevated levels of serum cholesterol in the pathogenesis of atherosclerosis and coronary heart disease. Various drugs targeting the key enzymes involved in the cholesterol biosynthesis pathway have been investigated for the treatment of hypercholesterolemia. Human squalene synthase has been one of the most important targets for therapeutic intervention.
