Linking the Ultraviolet Index to the “shadow rule” for sun protection: A theoretical model applied with a southern hemisphere example

Photochemistry and Photobiology, EarlyView.
We demonstrate the potential utility of the shadow rule and how it may be understood in relation to the UV Index. The shadow rule indirectly determines the sun's altitude by observing the length of a person's shadow during the course of the day. When the shadow cast by the sun on a horizontal surface is shorter than the height of the person casting the

Genetic risk variants implicate impaired maintenance and repair of periodontal tissues as causal for periodontitis—A synthesis of recent findings

Periodontology 2000, EarlyView.
AbstractPeriodontitis is a complex inflammatory disease in which the host genome, in conjunction with extrinsic factors, determines susceptibility and progression. Genetic predisposition is the strongest risk factor in the first decades of life. As people age, chronic exposure to the periodontal microbiome puts a strain on the proper maintenance of ...
