OSTEOPOROSIS FROM YESTERDAY TO TODAY – A NARRATIVE REVIEW.

Despite different lifestyles, humankind has suffered from osteoporosis for thousands of years. A literature review concerning the history of osteoporosis in the following databases: Index Medicus, Medline, PubMed, and PMC Citations was done. In the final analysis, 18 review articles and 31 original papers were included.

The effectiveness of global protected areas for climate change mitigation.

Forests play a critical role in stabilizing Earth's climate. Establishing protected areas (PAs) represents one approach to forest conservation, but PAs were rarely created to mitigate climate change. The global impact of PAs on the carbon cycle has not previously been quantified due to a lack of accurate global-scale carbon stock maps.

Flood hazards and risk mapping using geospatial technologies in Jimma City, southwestern Ethiopia.

Cities in Ethiopia are suffering from unprecedented floods due to climate change and other anthropogenic activities. Failure to include land use planning and poorly designed urban drainage system aggravates the problem of urban flood. The integration of geographic information system, and multi-criteria evaluation (MCE) technique were used for flood hazards and risk mapping.

Prepontine non-giant neurons drive flexible escape behavior in zebrafish.

Many species execute ballistic escape reactions to avoid imminent danger. Despite fast reaction times, responses are often highly regulated, reflecting a trade-off between costly motor actions and perceived threat level. However, how sensory cues are integrated within premotor escape circuits remains poorly understood.
