Whether FS combined with an even lower dose of estrogen is effective at preserving bone or whether FS interferes with the effect of this lower dose of estrogen is unknown. Thus, this study determined whether an ultra-low-dose (ULD) estrogen therapy, half the dose previously studied, in combination with FS preserved bone mass and strength

in the lumbar vertebrae in ovariectomized rats. Rats were treated for 12 wk with (1) basal diet (BD) (ovariectomized control), (2) BD + ULD estrogen implant, or (3) BD containing 10% buy DihydrotestosteroneDHT FS + ULD estrogen implant. A sham-operated control group was fed BD. Unlike ULD, FS + ULD attenuated loss of BMD and strength at the lumbar vertebrae and BMD in femurs and tibias. FS + ULD resulted in higher percentages of n-3 fatty acids including alpha-linolenic acid and eicosapentaenoic acid and lower percentages

of n-6 fatty acids including linoleic acid compared to all other groups. Differences in fatty acid selleck chemicals composition at the lumbar vertebrae and tibia were significantly related to BMD, BMC, and strength. No treatment-induced effects on uterus weight were observed, but histological analyses are needed to confirm safety. In conclusion, FS did not antagonize the activity of ULD, and their combination attenuated the loss of BMD and strength at the lumbar vertebrae, which was associated with differences in bone fatty acid composition.”
“The objective of this study was to evaluate whether exposure to disinfection by-products (DBP) is associated with colon cancer. A matched case-control study was used to investigate the relationship between the risk of death attributed to colon cancer and exposure to total trihalomethanes (TTHM) in drinking water in 65 municipalities in Taiwan. All colon cancer deaths of the 65 municipalities from 1997 through 2006 were obtained from the Bureau of Vital Statistics of the Taiwan

Provincial Department of Health. Controls were deaths from other causes and were pair-matched to the cancer cases by gender, year of birth, and year of death. Each matched control was selected randomly from the set of possible controls for each cancer case. Data on TTHM levels in drinking water in study municipalities were collected from the TPCA-1 Taiwan Environmental Protection Administration. The municipality of residence for cancer cases and controls was assumed to be the source of the subject’s TTHM exposure via drinking water. The adjusted odds ratios (OR) for colon cancer death for those with high TTHM levels in their drinking water were 1.02 (0.87-1.2) and 1.04 (0.89-1.21) compared to the lowest group. The results of the present study show that there was no statistically significant association between TTHM in drinking water at levels in this study and risk of death from colon cancer.”
