The fear of letting go and the Ivory Tower of dental educational training.

Issue: Clinical training in dental education is complex and happens mostly within a well-controlled environment such as a university dental clinic where oral health care services are delivered; it is mostly student-centered. While such training is important, it is also possible to augment and enhance it by training predoctoral dental students outside such a clinic within off-site community-based placements using a more person-centered approach. However, there seems to exist a reluctance in recognizing and utilizing the work produced in these off-site placements holistically as an integral part of students' clinical assessment.

Production of Gibberellic Acid by Solid-State Fermentation Using Wastes from Rice Processing and Brewing Industry.

Gibberellic acid (GA) is a natural hormone present in some plants used in agricultural formulations as a growth regulator. Currently, its production on an industrial scale is performed by submerged fermentation using the fungus Gibberella fujikuroi, which is associated with low yields, leaving the purification stages with high costs. An alternative is solid-state fermentation (SSF), which makes it possible to obtain higher concentrations of product using low-cost substrates, such as agroindustrial by-products.
