Notch regulates vascular collagen IV basement membrane through modulation of lysyl hydroxylase 3 trafficking.

Angiogenesis 2021 May 6. Epub 2021 May 6.

Department of Biological Sciences, University of Denver, Denver, CO, 80210, USA.

Collagen type IV (Col IV) is a basement membrane protein associated with early blood vessel morphogenesis and is essential for blood vessel stability. Defects in vascular Col IV deposition are the basis of heritable disorders, such as small vessel disease, marked by cerebral hemorrhage and drastically shorten lifespan. To date, little is known about how endothelial cells regulate the intracellular transport and selective secretion of Col IV in response to angiogenic cues, leaving a void in our understanding of this critical process.

Precision Medicine Considerations for the Management of Heart Disease and Stroke in East Asians.

Cardiol Plus 2020 Jul-Sep;5(3):101-108. Epub 2020 Sep 30.

Department of Anesthesiology, Perioperative and Pain Medicine, School of Medicine, Stanford University, Stanford, California, USA.

Heart disease is the leading cause of death in Asian Americans. Importantly, people of East Asian descent are more likely to carry a loss-of-function point mutation in aldehyde dehydrogenase 2 (ALDH2), ALDH2*2, which reduces ALDH2 enzymatic activity by at least 40% relative to wild type ALDH2. Given the role of ALDH2 in removing toxic aldehydes from the cell, ALDH2 is intimately involved in the cardioprotective mechanisms of ischemic preconditioning and the pathophysiology of ischemia reperfusion injury.

Select hyperactivating NLRP3 ligands enhance the T1- and T17-inducing potential of human type 2 conventional dendritic cells.

Sci Signal 2021 Apr 27;14(680). Epub 2021 Apr 27.

Laboratory of Dendritic Cell Biology, Department of Dermatology, University Hospital Erlangen, Friedrich-Alexander University of Erlangen-Nürnberg, 91052 Erlangen, Germany.

The detection of microorganisms and danger signals by pattern recognition receptors on dendritic cells (DCs) and the consequent formation of inflammasomes are pivotal for initiating protective immune responses. Although the activation of inflammasomes leading to secretion of the cytokine IL-1β is typically accompanied by pyroptosis (an inflammatory form of lytic programmed cell death), some cells can survive and exist in a state of hyperactivation. Here, we found that the conventional type 2 DC (cDC2) subset is the major human DC subset that is transcriptionally and functionally poised for inflammasome formation and response without pyroptosis.

A Novel Endoscopic Technique for Biopsy and Tissue Diagnosis for a Paraspinal Thoracic Tumor in a Pediatric Patient: A Case Report.

Int J Spine Surg 2021 Feb 29;14(s4):S66-S70. Epub 2020 Dec 29.

Warren Alpert Medical School of Brown University, Rhode Island Hospital, Providence, RI.

Background: Conventional approaches to the thoracic spine can require extensive tissue dissection, bony disruption, and instability that may warrant the need for instrumentation and fusion. Furthermore, anterior approaches may require the involvement of various surgeons from multiple disciplines to ensure a successful operation and mitigate complications. Currently, available minimally invasive approaches still require bony removal and usually rely heavily on computed tomography (CT)-guided imaging without direct gross visualization. Read More

A genome-wide analysis of cardiac lesions of pigs that die during transport: Is heart failure of in-transit-loss pigs associated with a heritable cardiomyopathy?

Can J Vet Res 2021 Apr;85(2):119-126

Department of Population Medicine, University of Guelph, 50 Stone Road East, Guelph, Ontario N1G 2W1 (Zurbrigg, Friendship, O'Sullivan); Department of Animal Science, Iowa State University, Ames, Iowa 50011, USA (Bertolini, Walugembe, Rothschild); National Institute of Aquatic Resources, Technical University of Denmark, Lyngby, Denmark (Bertolini); Veterinary Pathology Consultant, Ontario (van Dreumel), Veterinary Epidemiology Consultant, Elora, Ontario (Alves).

While heart failure is a primary cause of death for many in-transit-loss (ITL) pigs, the underlying cause of these deaths is not known.

The left ventricular assist device as a patient monitoring system.

Ann Cardiothorac Surg 2021 Mar;10(2):221-232

Center for Medical Physics and Biomedical Engineering, Medical University of Vienna, Vienna, Austria.

Technological progress of left ventricular assist devices (LVADs) towards rotary blood pumps and the optimization of medical management contributed to the significant improvements in patient survival as well as LVAD support duration. Even though LVAD therapy is now well-established for end-stage heart failure patients, the long-term occurrence of adverse events (AE) such as bleeding, infection or stroke, still represent a relevant burden. An early detection of AE, before onset of major symptoms, can lead to further optimization of patient treatment and thus mitigate the burden of AE. Read More

Institute for Experimental Cardiovascular Medicine, University Heart Center Freiburg Bad Krozingen, and Faculty of Medicine, University of Freiburg, 79110 Freiburg, Germany.

The mechanical environment of cardiac cells changes continuously and undergoes major alterations during diseases. Most cardiac diseases, including atrial fibrillation, are accompanied by fibrosis which can impair both electrical and mechanical function of the heart. A key characteristic of fibrotic tissue is excessive accumulation of extracellular matrix, leading to increased tissue stiffness. Read More
