The new guidelines for the management of peripheral arterial and aortic diseases (PAAD) from the European Society of Cardiology and endorsed by the European Society of Vascular Medicine (ESVM), emphasize on a comprehensive and multidisciplinary approach focusing on prevention, diagnosis, treatment, and follow-up of patients with a wide range of PAAD, including lower extremity peripheral arterial disease (PAD). The aim of this summary, focusing on PAD and coordinated by the Young Academy of ESVM, is to provide young angiologists with the fundamental principles of these guidelines and to assist them in navigating their everyday clinical practice. PAD diagnosis relies on objective evaluation of flow/oxygen reduction at rest, with arterial ultrasound as the first imaging modality to confirm the presence of arterial lesions.

The AAA protease FtsH associates with HflK/C subunits to form a megadalton-size complex that spans the inner membrane and extends into the periplasm of E. coli. How this bacterial complex and homologous assemblies in eukaryotic organelles recruit, extract, and degrade membrane-embedded substrates is unclear.

Osteochondrosis is a common disease that has been described in several farm and pet species as well as in some wildlife species, including captive roan antelope (Hippotragus equinus), a giraffe (Giraffa camelopardalis reticulata), snow leopard (Panthera uncia), and free-ranging wild boar (Sus scrofa ferus). It has not previously been confirmed in gray wolves (Canis lupus lupus). Postmortem radiographs of three free-ranging, juvenile sibling wolves revealed osteochondrosis in at least one of the glenohumeral joints (GHJs) in all individuals.
