[Pseudoaneurysm of the mitro-aortic trigone: Clinical case and literature review].

Case Report: We report the case of a 63-year-old patient who underwent aortic valve replacement with a biological valve for a bicuspid aortic stenosis, and LIMA-IVA single-bypass surgery. Two weeks later, he presented with Enterococcus faecillis bacteremia, attributed to left pyelonephritis and successfully treated with Amoxicillin. Two months after his surgery, he had a new bacteremia due to Enterococcus faecalis and we discovered a pseudo-aneurysm of the mitro-aortic trigone.

Epicardial Fat Volume Assessed by MRI in Adolescents: Associations with Obesity and Cardiovascular Risk Factors.

: In adults, epicardial adipose tissue (EAT) is associated with metabolic syndrome (MS) and coronary artery disease. EAT thickness is increased in obese youth, but total EAT volume and its correlation with cardiovascular risk factors have not been studied. : To determine EAT volume in adolescents and its association with obesity and cardiovascular risk factors.

Zweifel olefination for C-glycosylation.

C-glycosides are significant in medicinal chemistry due to their resistance to enzymatic hydrolysis, making them more stable and bioavailable compared to O-glycosides. Their unique structure also offers potential for developing drugs with improved therapeutic properties, particularly in treating diseases like diabetes and cancer. The main challenge in synthesizing C-glycosides lies in forming the carbon-carbon bond between the sugar and aglycone efficiently, while controlling the stereochemistry and minimizing side reactions.

Stereoselective polar radical crossover for the functionalization of strained-ring systems.

Radical-polar crossover of organoborates is a poweful tool that enables the creation of two C-C bonds simultaneously. Small ring systems have become essential motifs in drug discovery and medicinal chemistry. However, step-economic methods for their selective functionalization remains scarce.

Strain-release arylations for the bis-functionalization of azetidines.

The addition of nucleophilic organometallic species onto generated azabicyclobutanes enables the selective formation of 3-arylated azetidine intermediates through strain-release. Single pot strategies were further developed for the -arylation of resulting azetidines, employing either SAr reactions or Buchwald-Hartwig couplings.
