Nonoperative and Operative Soft-Tissue, Cartilage, and Bony Regeneration and Orthopaedic Biologics of the Shoulder: An Orthoregeneration Network (ON) Foundation Review.

Arthroscopy 2021 Jul 19. Epub 2021 Jul 19.

Midwest Orthopaedics at Rush, Chicago, IL, USA. Electronic address:

Orthoregeneration is defined as a solution for orthopaedic conditions that harnesses the benefits of biology to improve healing, reduce pain, improve function, and optimally, provide an environment for tissue regeneration. Options include drugs, surgical intervention, scaffolds, biologics as a product of cells, and physical and electro-magnetic stimuli. The goal of regenerative medicine is to enhance the healing of tissue after musculoskeletal injuries as both isolated treatment and adjunct to surgical management, using novel therapies to improve recovery and outcomes.

Osteogenic and Regenerative Potential of Free Gingival Graft.

Bull Exp Biol Med 2021 Jul 22. Epub 2021 Jul 22.

Department of Histology, Embryology and Cytology, Pacific State Medical University, Ministry of Health of the Russian Federation, Vladivostok, Russia.

We studied immunolocalization of CD29, CD44, osteocalcin, and TGF-β1 in the bone tissue of the mandible of miniature pigs with extra-bone fixation of a free gingival graft. Three months after surgery, neoosteogenesis foci with high expression of the studied markers were found in the contact area of the free gingival graft with the alveolar bone. The markers were localized in the layer of external circumferential lamellae, on the surface of concentric lamellae of the growing osteons, and in the connective tissue of the Haversian canals.

Polydiacetylene Liposome Microarray toward Facile Measurement of Platelet Activation in Whole Blood.

ACS Sens 2021 Jul 22. Epub 2021 Jul 22.

Department of Materials Science and Engineering, University of Michigan, Ann Arbor, Michigan 48109, United States.

The necessity of a simple measurement of platelet activation has been increasing in clinical medicine to regulate the proper dose of the antiplatelet drugs for patients having clinical outcomes in acute situations such as angina pectoris, stroke, or peripheral vascular disease or procedures involving angioplasty or coronary thrombolysis. We developed a self-signaling polydiacetylene (PDA) liposome microarray to detect activated platelets from whole blood samples in a single step. A specific antibody, 9F9 antibody, to platelet-bound fibrinogen was selected and conjugated to the PDA liposome microarray to quantify the fibrinogen-bound platelets. Read More

Presence of Donor Lymph Nodes Within Vascularized Composite Allotransplantation Ameliorates VEGF-C-mediated Lymphangiogenesis and Delays the Onset of Acute Rejection.

Transplantation 2021 Aug;105(8):1747-1759

Department for BioMedical Research, University of Bern, Bern, Switzerland.

Background: The lymphatic system plays an active role in modulating inflammation in autoimmune diseases and organ rejection. In this work, we hypothesized that the transfer of donor lymph node (LN) might be used to promote lymphangiogenesis and influence rejection in vascularized composite allotransplantation (VCA).

Methods: Hindlimb transplantations were performed in which (1) recipient rats received VCA containing donor LN (D:LN+), (2) recipient rats received VCA depleted of all donor LN (D:LN-), and (3) D:LN+ transplantations were followed by lymphangiogenesis inhibition using a vascular endothelial growth factor receptor-3 (VEGFR3) blocker.

Rare anastomosis between the ascending pharyngeal and vertebral arteries via the hypoglossal canal: A cadaveric case report.

Anat Cell Biol 2021 Jul 22. Epub 2021 Jul 22.

Department of Neurosurgery, Tulane University School of Medicine, New Orleans, LA, USA.

We present a rare case of external carotid artery-vertebral artery anastomosis via the ascending pharyngeal artery, diagnosed upon cadaveric dissection. The ascending pharyngeal artery gave rise to a branch to the hypoglossal canal, which is a variation of a true persistent fetal hypoglossal artery. Knowledge of persistent carotid-vertebrobasilar anastomoses is important as these fetal vessels can contribute significantly to the posterior cerebral circulation. Read More

Transcatheter therapies for secondary mitral regurgitation in advanced heart failure: what are we aiming for?

Heart Fail Rev 2021 Jul 22. Epub 2021 Jul 22.

Division of Cardiology, San Raffaele Scientific Institute, Milan, Italy.

A severe secondary mitral regurgitation (SMR) can be found in a significant portion of patients affected by advanced heart failure (AHF). Conventional therapies (optimal medical therapy, devices, surgery) present restricted clinical efficacy in this stage of the left ventricle disease which is burdened by high mortality and morbidity rates. Although the treatment of choice is represented by heart transplantation (HTx), there is an unmet need related to the limited supply of donor hearts (as opposed to the growing prevalence of AHF) and the low eligibility of highly symptomatic patients.

Olfactory nerve sparing technique for anterior skull base meningiomas: how I do it.

Acta Neurochir (Wien) 2021 Jul 22. Epub 2021 Jul 22.

Department of Neurosurgery, Fondazione IRCCS Istituto Neurologico Carlo Besta, Via Celoria 11, 20133, Milan, Italy.

Background: Olfactory function preservation is a desirable objective in anterior skull base (ASB) surgery. The "infracerebral-supraolfactory nerve" corridor is presented.

Method: The technique for preserving the olfactory nerves (OlfNs) in anterior ASB meningioma removal involves the following points: deep knowledge of the ASB vascular and meningeal anatomy, precise preoperative planning, wide and sharp dissection of the OlfNs away from the frontal lobes, gravity-aided frontal lobe retraction, Gelfoam-assisted hemostasis on nervous structures, and access to the lesion through an infracerebral-supraolfactory nerve corridor.
