Raloxifene hydrochloride, a selective oestrogen receptor modulator, has been shown to increase bone mineral density and decrease biochemical markers of bone turnover in postmenopausal women, without stimulatory effects on breast or uterus. Levels of proinflammatory cytokines, including IL-6, and TNF-alpha and TGF-beta1 which are important cytokines involved in remodeling, have been evaluated previously in in vitro studies of osteoporosis. However, there seems to be a paucity of in vivo research concerned with changes in these cytokines in osteoporosis. In this study, we evaluated the effects of raloxifene (Evista); Lilly Pharmaceutical Co. USA, 60 mg/day) on biochemical bone turnover markers, serum parathyroid hormone, and 25-OH vitamin D, as well as the serum levels of IL-6, TNF-alpha and TGF-beta1, in 22 p...

The aim of this study is to introduce a scientific and systematic approach for determination of fault rates in most frequent property damage only (PDO) traffic accidents in Turkey. In this study, data (police reports, skid marks, deformation situation of involvements, crush depth, etc.) collected from the most-frequent and controversial accident types (four sample vehicle-vehicle scenarios), which consist of property damage only (PDO), were inserted into a reconstruction software called vCrash. Sample real world scenarios were simulated on the software to generate different deformations on vehicles which also correspond to energy equivalent speed (EES) dat...

Both gases are emitted from fossil fuels and biomass burning, while methane alone has large sources from wetlands, agriculture, landfills and wastewater. Here we use measurements in firn air from Greenland and Antarctica to reconstruct the atmospheric variability of ethane during the 20th century. Ethane levels rose from early in the century until the 1980’s when the trend reverses, with a period of decline over the next 20 years. This variability is primarily driven by changes in ethane emissions from fossil fuels that peaked in the 1960’s and 1970’s at 14-16 Tg/y and dropped to 8-10 Tg/y before the end of the century. The reduction in fossil-fuel sources is likely related to changes in light hydrocarbon recovery during petroleum production and use. The ethane-based emission history implies that the decline in the fossil-fuel source of methane may have started prior to the 1980’s and that the magnitude of the decline is larger than previous estimates.
