Aims Poly (ADP-ribose) polymerase (PARP) inhibitor has been reported to attenuate inflammatory response in rat models of inflammation. This study was designed to investigate the effect of PARP signalling in osteoarthritis (OA) cartilage inflammatory response in an OA rat model. Methods The OA model was established by anterior cruciate ligament transection with medial meniscectomy in Wistar rats. The poly (ADP-ribose) polymerase 1 (PARP-1) shRNA (short hairpin (sh)-PARP-1) and negative control shRNA (sh-NC) were delivered using a lentiviral vector and were intra-articularly injected into rats a

Membrane-free stem cell components (MFSCC) from basal adipose tissue-derived stem cells (ADSCs) are unknown for the treatment strategies in osteoarthritis (OA). OA has been considered to be associated with inflammatory damage and cartilage degradation. In this study, we intended to investigate the molecular mechanism of the anti-inflammation and cartilage protection effect of MFSCC in vitro (rat primary chondrocytes) and in vivo (rat OA model). The MFSCC treatment significantly inhibited interleukin-1α (IL-1α) stimulated inflammation and cartilage degradation. The MFSCC considerably reduced th

BACKGROUND: Osteoarthritis (OA) is a degenerative joint disease in one or more joints characterized by changes in pathological structures such as cartilage, hypertrophy, and remodeling of the subchondral bone and secondary inflammation of the synovium membrane, causing changes in joint components such as cells, matrices, and molecular production. At the molecular level, an imbalance between catabolic and anabolic activities in joint cartilage results in OA. Nuclear factor kappa beta (NFκβ) is a cytokine that plays an important role in the signaling pathway of the pathogenesis of OA in causing

Objective To study the therapeutic effect and mechanism of action of quercetin in a rat model of osteoarthritis (OA). Methods The OA rat model was established by intra-articular injection of papain. Changes in knee diameter, toe volume and histopathology were measured. Levels of interleukin (IL)-β and tumor necrosis factor (TNF)-α were assessed by ELISA. Relative expression of Toll-like receptor (TLR)-4 and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) was evaluated by western blotting.

Biomarkers of osteoarthritis (OA) that can accurately diagnose the disease at the earliest stage would significantly support efforts to develop treatments for prevention and early intervention. We have sought to determine the time course of alterations in peripheral blood gene expression profile associated with the development of OA. Blood samples were collected from a tail vein of individual rats with monosodium iodoacetate- (MIA-) induced OA (2, 14, 21, and 28 days after the treatment).

Background: Autophagy, a self-protective mechanism of chondrocytes, has become a promising target to impede the progress of osteoarthritis (OA). Autophagy is regulated by cytosolic Ca2+ activity and may thus be modified by the Ca2+ permeable transient receptor potential channel vanilloid 5 (TRPV5). Therefore, we investigated the potential role of TRPV5 in mediating Ca2+ influx and in inhibiting chondrocyte autophagy in a rat OA model.

Knee Osteoarthritis (OA) is one of the most common forms of arthritis and is primarily a degenerative joint disease. It causes pain, stiffness, and loss of movement in the knee joint by affecting the surrounding tissues, bones, and cartilage. Manual diagnosis of this condition involves looking at knee region X-ray images and using the Kellgren-Lawrence (KL) system to categorize severity levels. Conventional techniques for identifying and classifying osteoarthritis, such as manual radiography evaluation, are frequently laborious and subjective.

Osteoarthritis (OA) is best described as a chronic pain syndrome affecting one, or more frequently, multiple joints. It most commonly affects the knees, hips, hands, neck and lower back, although any joint can be affected. Defining OA by pathological changes is no longer con­sidered best practice, as the correlation between path­ology and symptoms is frequently discordant, i.e. patients with severe structural changes may present with min­imum symptoms and vice versa. For this reason, patients should be assessed using a biopsychosocial model, which takes into consideration impact on social and

Abstract Imidazolines have been used in the area of corrosion inhibition since at least the mid 1940’s when it was shown that long chain organic compounds with polar functional groups had corrosion inhibition properties when applied to oil-field environments. Part I. of this paper reported the synthesis, separation/isolation and performance characteristics of various imidazoline species synthesised from oleic acid (OA) and diethylenetriamine (DETA). These techniques have been employed in order to yield relatively ‘pure’ imidazolines for more detailed study. This paper presents the preliminary

Orofacial pain associated with osteoarthritis (OA) in the temporomandibular joint (TMJ) is a significant clinical problem [1]. The pathophysiologic and cellular mediators that underlie the development of such chronic orofacial pain are not well understood, nor has a relationship to mechanical loading been defined. Several experimental models have been developed to examine causative factors in TMJ OA progression and joint pathology. Such models often involve intra-articular injections or surgical manipulation of tissue structures in order to alter joint kinematics and stability [2–6]. For examp

According to the Arthritis Foundation, 66 million Americans (or nearly 1 in 3 adults) currently suffer from arthritis, with osteoarthritis (OA) being the most common form, and the knee being the joint most commonly affected. Despite the need for early treatment, few clinical interventions slow the progression of knee OA. Since articular cartilage is responsive to the amount of joint loading, reducing compressive loads in the diseased compartment may slow the rate of cartilage breakdown. Because medial compartment load cannot be measured non-invasively in vivo, an external measure to quantify t

This study conducts a quantitative analysis of the inclusion of open access (OA) academic books in the OpenAlex and Web of Science (WoS) databases from 2004 to 2023. It explores the differences and trends between the two databases in terms of the number of OA books, annual variations, and disciplinary distribution. The study finds that OpenAlex shows a significant advantage over WoS in the scale of OA book inclusion and growth rate, with a particularly strong growth potential in recent years.

Holographic correction for telescope lens distortions was first proposed and realised yet in 70-es1; in this and more recent experiments2 the holograms were recorded in the static media, providing thus correction only for static distortions. The prospective scheme, which can be used for real-time dynamic correction in wide spectral range, uses thin (plain) dynamic hologram record in the optically addressed liquid crystal spatial light modulators (OA LC SLM).
