Glucagon-like peptide-1 (GLP-1) receptor activation dilates cerebral arterioles, increases cerebral blood flow, and mediates remote (pre)conditioning neuroprotection against ischaemic stroke.

Basic Res Cardiol 2021 May 3;116(1):32. Epub 2021 May 3.

Centre for Cardiovascular and Metabolic Neuroscience, Neuroscience, Physiology and Pharmacology, University College London, Gower Street, London, WC1E 6BT, UK.

Stroke remains one of the most common causes of death and disability worldwide. Several preclinical studies demonstrated that the brain can be effectively protected against ischaemic stroke by two seemingly distinct treatments: remote ischaemic conditioning (RIC), involving cycles of ischaemia/reperfusion applied to a peripheral organ or tissue, or by systemic administration of glucagon-like-peptide-1 (GLP-1) receptor (GLP-1R) agonists. The mechanisms underlying RIC- and GLP-1-induced neuroprotection are not completely understood. Read More

Arterial Thrombotic Sequalae After Covid-19: Mind The Gap.

Ann Vasc Surg 2021 Apr 30. Epub 2021 Apr 30.

Unit of Vascular and Endovascular Surgery, General Surgery Department, University Hospital of Udine, Udine, Italy.

Investigations have shown that infection from the severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) is responsible also for initiating severe inflammatory responses that can lead macrovascular and microvascular thrombosis. Several studies have already described acute limb ischemia and peripheral arterial disease in critically ill patients with Coronavirus disease 2019 (Covid-19), as well as coronary artery disease and ischemic stroke as a manifestation usually associated with respiratory distress. However, what still remains unclear is how long inflammation and thrombotic derangements can last after recovery from the symptoms of Covid-19. Read More

Safety of Silk-elastin Sponges in Patients with Chronic Skin Ulcers: A Phase I/II, Single-center, Open-label, Single-arm Clinical Trial.

Plast Reconstr Surg Glob Open 2021 Apr 28;9(4):e3556. Epub 2021 Apr 28.

Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

Background: Although traditional wound dressings such as collagen scaffolds promote granulation tissue formation, the efficacy of these dressings in chronic wounds is limited because of high susceptibility to bacterial growth. Biomaterials that can be applied to chronic wounds should have an anti-bacterial function. We previously reported that administering a silk-elastin solution that forms moisturizing hydrogels to wound surfaces of diabetic mice reduced bacterial growth and promoted granulation tissue formation compared with control or carboxymethyl cellulose hydrogels.
