Osteoarthritis, or OA, is the most common joint disease affecting middle - age and older people.
Oceanic uptake of anthropogenic carbon dioxide (CO2) causes pronounced shifts in marine carbonate chemistry and a decrease in seawater pH. Increasing evidence indicates that these changes — summarized by the term ocean acidification (OA)-- can significantly affect marine food webs and biogeochemical cycles.
Aim Experimental simulation of near ‐ future ocean acidification (OA) has been demonstrated to affect growth and development of echinoderm larval stages through energy allocation towards ion and pH compensatory processes.
Osteoarthritis (OA) is a degenerative condition which affects the cartilage of the body's joints.
«Sometimes called degenerative joint disease or degenerative arthritis, osteoarthritis (OA) is the most common chronic condition of the joints, affecting approximately 27 million Americans.»
It is a degenerative disease affecting the whole joint, and any joint can be affected but OA most commonly affects the knees, hips, hands, neck and low back.
Osteoarthritis (OA), the most common form of arthritis, affects mainly...
Degenerative joint disease or osteoarthritis (OA) is the most common joint disorder in the United States affecting more than 30 million adults.
While OA can affect any joint in your body, it primarily occurs in knees, hands, spine, and hips.
As part of this process, DOT, it's OAs, and recipients of Federal financial assistance will provide appropriate and meaningful opportunities for comment by representatives of potentially affected communities.
DOT is committed to engaging minority and low - income populations in the transportation decision - making process across all relevant OAs, from the earliest stages of planning through project implementation, including maintenance and operation, to ensure that affected communities are able to influence decision outcomes.
By some estimates, 20 % of dogs of all ages are affected by OA.
By most estimates, 20 % of all dogs (regardless of age) are affected by OA, making it the most common chronic disease they face.
Osteoarthritis (OA) affects approximately 20 percent of our cat and dog population, and the incidence increases with age.
A previous trauma affecting a joint or the bones around a joint may also lead to progression of OA.
By most estimates, 90 % of cats over age 10 are affected by OA, making it the most common chronic disease they face.
Thus, predictions of future trajectories of pH in coastal ecosystems are still highly uncertain even though model predictions can provide reliable predictions for the future trajectories of open - ocean pH and, thereby, the open - ocean end - member affecting coastal pH. Moreover, we argue that even the expectation that the component of coastal pH change associated with OA from anthropogenic CO2 will follow the same pattern as that in the open ocean is not necessarily supported.
However, the conditions predicted for the open ocean may not reflect the future conditions in the coastal zone, where many of these organisms live (Hendriks et al. 2010a, b; Hofmann et al. 2011; Kelly and Hofmann 2012), and results derived from changes in pH in coastal ecosystems often include processes other than OA, such as emissions from volcanic vents, eutrophication, upwelling and long - term changes in the geological cycle of CO2, which commonly involve simultaneous changes in other key factors affecting the performance of calcifiers, thereby confounding the response expected from OA by anthropogenic CO2 alone.
This new concept of anthropogenic impacts on seawater pH formulated here accommodates the broad range of mechanisms involved in the anthropogenic forcing of pH in coastal ecosystems, including changes in land use, nutrient inputs, ecosystem structure and net metabolism, and emissions of gases to the atmosphere affecting the carbon system and associated pH. The new paradigm is applicable across marine systems, from open - ocean and ocean - dominated coastal systems, where OA by anthropogenic CO2 is the dominant mechanism of anthropogenic impacts on marine pH, to coastal ecosystems where a range of natural and anthropogenic processes may operate to affect pH.
However, there have been relatively few studies that have investigated the impacts of OA on microbial processes, particularly those that affect the major biogeochemical cycles within the ocean [3,4].
