Pseudolaric acid B ameliorates synovial inflammation and vessel formation by stabilizing PPARγ to inhibit NF-κB signalling pathway.

J Cell Mol Med 2021 Jun 11. Epub 2021 Jun 11.

Department of Immunology, School of Basic Medical Sciences, Southern Medical University, Guangzhou, China.

Synovial macrophage polarization and inflammation are essential for osteoarthritis (OA) development, yet the molecular mechanisms and regulation responsible for the pathogenesis are still poorly understood. Here, we report that pseudolaric acid B (PAB) attenuated articular cartilage degeneration and synovitis during OA. PAB, a diterpene acid, specifically inhibited NF-κB signalling and reduced the production of pro-inflammatory cytokines, which further decreased M1 polarization and vessel formation. Read More

Osteochondritis Dissecans: Current Understanding of Epidemiology, Etiology, Management, and Outcomes.

J Bone Joint Surg Am 2021 Jun;103(12):1132-1151

Department of Orthopedic Surgery, University of Minnesota, Minneapolis, Minnesota.

: Osteochondritis dissecans occurs most frequently in the active pediatric and young adult populations, commonly affecting the knee, elbow, or ankle, and may lead to premature osteoarthritis.

: While generally considered an idiopathic phenomenon, various etiopathogenetic theories are being investigated, including local ischemia, aberrant endochondral ossification of the secondary subarticular physis, repetitive microtrauma, and genetic predisposition.

: Diagnosis is based on the history, physical examination, radiography, and advanced imaging, with elbow ultrasonography and novel magnetic resonance imaging protocols potentially enabling early detection and in-depth staging. Read More

Changes to the activity and sensitivity of nerves innervating subchondral bone contribute to pain in late-stage osteoarthritis.

Pain 2021 Jun 3. Epub 2021 Jun 3.

Department of Anatomy and Physiology, University of Melbourne, Victoria, Australia.

Abstract: Whilst it is clear that osteoarthritis (OA) pain involves activation and/or sensitization of nociceptors that innervate knee joint articular tissues, much less is known about the role of the innervation of surrounding bone. In this study, we used mono-iodoacetate (MIA)-induced OA in male rats to test the idea that pain in OA is driven by differential contributions from nerves that innervate knee joint articular tissues vs the surrounding bone. The time-course of pain behavior was assayed using the advanced dynamic weight bearing device, and histopathology was examined using H&E histology. Read More

Senolytics alleviate the degenerative disorders of temporomandibular joint in old age.

Aging Cell 2021 Jun 8:e13394. Epub 2021 Jun 8.

UConn Center on Aging, UConn Health, Farmington, CT, USA.

Aging is one of the major risk factors for degenerative joint disorders, including those involving the temporomandibular joint (TMJ). TMJ degeneration occurs primarily in the population over 65, significantly increasing the risk of joint discomfort, restricted joint mobility, and reduced quality of life. Unfortunately, there is currently no effective mechanism-based treatment available in the clinic to alleviate TMJ degeneration with aging. Read More

Systemic transplantation of adult multipotent stem cells prevents articular cartilage degeneration in a mouse model of accelerated ageing.

Immun Ageing 2021 Jun 7;18(1):27. Epub 2021 Jun 7.

Shirley Ryan Abilitylab (Formerly the Rehabilitation Institute of Chicago), 355 E. Erie St, IL, 60611, Chicago, USA.

Background: Osteoarthritis (OA) is one of the most prevalent joint diseases of advanced age and is a leading cause of disability worldwide. Ageing is a major risk factor for the articular cartilage (AC) degeneration that leads to OA, and the age-related decline in regenerative capacity accelerates OA progression. Here we demonstrate that systemic transplantation of a unique population of adult multipotent muscle-derived stem/progenitor cells (MDSPCs), isolated from young wild-type mice, into Zmpste24 mice (a model of Hutchinson-Gilford progeria syndrome, a condition marked by accelerated ageing), prevents ageing-related homeostatic decline of AC.

Review: Mesenchymal Stem Cell Therapy in Canine Osteoarthritis Research: "Experientia Docet" (Experience Will Teach Us).

Front Vet Sci 2021 19;8:668881. Epub 2021 May 19.

Department of Medical Imaging and Orthopedics of Domestic Animals, Faculty of Veterinary Medicine, Ghent University, Merelbeke, Belgium.

Osteoarthritis (OA) is currently an incurable and progressive condition in dogs causing chronic joint pain and possibly increasing disability. Due to the poor healing capacity of cartilage lesions that occur with OA, development of effective therapeutics is difficult. For this reason, current OA therapy is mostly limited to the management of pain and inflammation, but not directed ad disease modification. Read More

Systemic Transplantation of Adult Multipotent Stem Cells Functionally Rejuvenates Aged Articular Cartilage.

Aging Dis 2021 Jun 1;12(3):726-731. Epub 2021 Jun 1.

1Shirley Ryan AbilityLab, Chicago, Illinois, USA.

Osteoarthritis (OA) is the most common and debilitating joint disease of advanced age and has no universally effective therapy. Here, we demonstrate that systemic transplantation of adult multipotent muscle-derived stem/progenitor cells (MDSPCs)-isolated from young mice-rejuvenates the knee articular cartilage (AC) of naturally aged mice. This intervention reduced expression of pro-inflammatory cytokines ( and ) and catabolic matrix-degrading proteinases ( and ) in aged cartilage. Read More

Ear Nose Throat J 2021 Jun 6:1455613211014109. Epub 2021 Jun 6.

Department of Otorhinolaryngology and Head and Neck Surgery, University Hospital Ostrava, Ostrava-Poruba, Czech Republic.

Chondrosarcoma of the thyroid cartilage is a sporadic disease with nonspecific clinical presentation. Smooth swelling of the supraglottic area should arouse suspicion of possible pathology. In addition to laryngoceles, which usually do not have a significant impact, otolaryngologists should consider chondrosarcoma of the thyroid cartilage and indicate computed tomography (CT).

Return to sport following anterior cruciate ligament reconstruction: the argument for a multimodal approach to optimise decision-making: current concepts.

J ISAKOS 2021 Jun 4. Epub 2021 Jun 4.

Department of Orthopaedic Surgery, Stanford University, Redwood City, California, USA

Existing literature is varied in the methods used to make this determination in the treatment of athletes who have undergone recent anterior cruciate ligament (ACL) reconstruction. Some authors report using primarily time-based criteria, while others advocate for physical measures and kinematic testing to inform decision-making. The goal of this paper is to elucidate the most current medical evidence regarding identification of the earliest point at which a patient may safely return to sport. Read More

Ginkgolide J protects human synovial cells SW982 via suppression of p38‑dependent production of pro‑inflammatory mediators.

Mol Med Rep 2021 Aug 3;24(2). Epub 2021 Jun 3.

Faculty of Pharmacy, The University of Sydney, Sydney, NSW 2006, Australia.

Fibroblast‑like synoviocytes (FLS) in the synovial lining play a key role in the pathological process of rheumatoid arthritis (RA), which produce pro‑inflammatory mediators to perpetuate inflammation and proteases to contribute to cartilage destruction. Ginkgolide J (GJ) is a subclass of ginkgolides (GGs) that exhibits anti‑inflammatory activity. In the present study, the protective effect of GJ on lipopolysaccharide (LPS)‑treated human synovial cells SW982 and its related mechanisms were investigated using various methods, including ELISA, Griess assay, western blotting, immunofluorescence analysis and p38 kinase activity assay.
