Heading-Related Slowing by Twenty-Four Hours in Youth Athletes.

Research suggests cumulative effects of repetitive head impacts (RHIs) on brain structure, especially with younger age of first exposure. Further, recent evidence suggests no immediate cognitive changes with increased RHIs but impairments across a sports season. The aim was to examine more closely the short-term time course of behavioral effects of exposure to RHI.

Evaluation of salivary interleukin-6 in children with early childhood caries after treatment.

Background: The role of cytokines as a marker in the oral inflammatory process in ECC has not been fully explored before and after full mouth rehabilitation.

Aims: The aim of this study was to assess the level of salivary interleukin-6 (IL-6) in children with ECC and to compare its levels before and after comprehensive full mouth rehabilitation.

Methods And Materials: Saliva samples were collected from children with ECC prior to dental treatment and 3-month post treatment.

Marker assisted selection of low phytic acid trait in maize (Zea mays L.).

Maize is the third important major food crop. Breeding for low phytate maize genotypes is an effective strategy for decreasing the content of kernel phytic acid (a chelator of cations such as Ca(2+) and Fe(3+) ) and thereby increasing the bioavailability of nutritive minerals in human diet and animal feed. Previous studies have established that a mutant plant with a lpa2-2 allele accumulates less phytic acid in seeds.
