Bone impairment in adolescent female rats chronically exposed to ethanol
258-262Ethanol consumption has increased among teenagers worldwide considerably,including females. Long-term ethanol
consumption in women has been reported to cause bone metabolism imbalance. However, only few studies are available on
the impact of long-term ethanol consumptionon bone morphology during adolescence. Here, we report the effects of chronic
ethanol consumption on bone structure in adolescent female rats. Twenty female Wistar rats (35 days old) received, by
gavage, distilled water (control) or ethanol (6.5 g/kg/day, 22.5% w/v) once daily for 55 days. After ethanol administration,
animals were perfused, and the femora were collected. Morphometric evaluations were performed by electron microscopy
scanning. Femora length, cortical bone thickness and medullar bone diameter was measured. The results demonstrated that
ethanol exposure during adolescence reduced the length of femurs, with a decrease of the anterior thickness, posterior
thickness, and mid-lateral diameter (P<0.05). Thus, long-term ethanol intake may lead to alterations on bone morphometry,
reducing the thickness of compact bone and femur length in adolescent females
A scoping review on the use of portable air cleaners in healthcare settings
The purpose of this scoping review is to map methodologies and outcome measurements used to assess the performance of portable air-cleaning technologies in dental and medical settings, identify gaps, and propose recommendations for future research
