Anecdotal suggestions and retrospective studies indicate an inverse relationship between the incidence of osteoarthritis and individuals who smoke. As a possible explanation, our studies confirm that nicotine upregulates glycosaminoglycan and collagen synthetic activity of articular chondrocytes at
The aims of the study were to show the direct effect of nicotine with different concentrations (0, 25, 50, and 100 ng/ml) on chondrocytes isolated from normal human and osteoarthritis patients, respectively. Microscopic observation was performed during the culture with an inverted microscope. Methyl
The deleterious effects of nicotine on various health conditions have been well documented. Although many orthopedic diseases are adversely affected by nicotine, little is known about its preclinical effects on chondrogenesis or osteogenesis, cartilage formation, osteoarthritis (OA), and
Epidemiological investigations indicate that effects related to prenatal adverse environments on the organs of the offspring could continue to adulthood. This study intends to confirm that prenatal nicotine exposure (PNE) increases the susceptibility of osteoarthritis (OA) in the male offspring, and
OBJECTIVE
To examine differences between tobacco users and nonusers who required surgical treatment for degenerative joint disease (DJD) of the spine.
METHODS
Two hundred randomly selected medical records of patients who had undergone surgery for DJD of the spine.
CONCLUSIONS
The number of tobacco
Osteoarthritis (OA) is a degenerative joint disease that causes chronic disability among the elderly. Despite recent advances in symptomatic management of OA by pharmacological and surgical approaches, there remains a lack of optimal approaches to manage inflammation in the joints, which causes
The objective of the study was to investigate the effects of nicotine on articular cartilage degeneration and inflammation in a rat model of early stage osteoarthritis (OA), using T2 mapping. In this study, a rat model of early stage OA was established by immobilizing the left knee joints of adult
Chondrocyte apoptosis is mainly responsible for the progressive degeneration of cartilage in osteoarthritis (OA). Interleukin-1beta (IL-1β) was widely used as a modulating and chondrocyte apoptosis-inducing agent. Nicotine is able to confer resistance to apoptosis and promote cell survival in some
This study aimed to evaluate whether female adult offspring born with intrauterine growth retardation induced by prenatal nicotine exposure (PNE) are susceptible to osteoarthritis (OA) and to explore the underlying programming mechanisms. Pregnant rats were treated with nicotine or saline at 2.0
Besides inhalation, a few studies have indicated that the uptake of nicotine through air or clothing may be a significant pathway of its exposure among passive smokers. Nicotine is well known to exert various physiological impacts, including stimulating sympathetic nervous system, causing vascular
Osteoarthritis (OA) is a chronic disease with a very high incidence and the pathology of which is quite complex. Epidemiological investigation showed that OA may be related to smoking and estrogen levels, but there are few studies focused on the cross-effect of these two factors. This OBJECTIVE
Despite the rising number of patients with osteoarthritis, no sufficient chondroprotective and prophylactic therapy for osteoarthritis has been established yet. The purpose of this study was to verify whether stimulation of the nicotinic acetylcholine receptor via nicotine has a beneficial
BACKGROUND
Osteoarthritis (OA) is a chronic joint disease characterized by a progressive and irreversible degeneration of articular cartilage. Among the environmental risk factors of OA, tobacco consumption features prominently, although, there is a great controversy regarding the role of tobacco
BACKGROUND
Although smoking is a well-accepted risk factor for surgical complications, the effect of smoking on patient-reported outcomes (PROs) has not been previously investigated. Prompted by an increasingly value-conscious healthcare environment, the purpose of this study is to investigate the
OBJECTIVE
Nicotine has been reported that it has a dose-dependent effect on matrix mineralization by human bone marrow cells. However, there is no relevant research concerning on chondrogenic differentiation potential of bone marrow stromal stem cells (BMSCs) treated with nicotine in vitro. The aims
