Thus, we use three types of data to characterize fruit nitrogen content of a given site: comprehensive sampling of all fruits obtained during a study, fruits eaten by primates, and fruits eaten and not eaten by primates if non-eaten fruits had been collected for comparisons. To control for possible physiological differences between primate radiations, we investigated whether the nitrogen content of all dietary plant components CH5138303 differed between primate radiations. Osteoporosis, marked by low bone density, is a common geriatric disease. The NHANES Study III reported that the frequency of osteoporosis more than doubles from decade fifties to eighties. Osteoporosis is clinically marked with a fracture event. Risk of Parthenolide fractures increases with age ; largest cost of osteoporosis being ascribed to hip fractures. Additional costs can arise due to long-term care and dependency. A study reported a decline in the activities of daily living in people with osteoporosis. It appears thus that, osteoporosis could impact functional status and life-quality. As like the ADL, the Timed-up-and-go test, an index for physical mobility, is yet another geriatric tool indexing functional status. TUG is often used to predict fractures; though specifically more often used to predict falling. Since around 89% of fractures are triggered by falling, TUG is required to be controlled for, for outcomes like falling and fractures. Higher rate of osteoporosis has been also observed in people with lower mobility. A physiological explanation could be that the loss of muscles, sarcopenia or weight loss, lowers bone density. Yet not much is known about the relationship of osteoporosis per se and functional status. Osteoporosis poses an existing public health challenge, which can be expected to rise, given the prognosis of a growing elderly population. A political will towards a greater investment in health-care is in consideration and some parts of world are grappling with huge cost of osteoporosis that prevention seems a suitable alternative. However, often due to the association of fractures as a clinical end-point in the practical diagnosis of osteoporosis, it renders the situation too late for a timely osteoporosis control.
