Evaluation of Different Dental Lasers' Ability to Congeal Pooled Blood: An In Vitro Study.

Most dental lasers claim that they can aid in hemostasis during oral and periodontal surgery. To date, there are no studies that compare different lasers' ability to congeal pooled blood. The aim of the study was to see if there was a difference in dental lasers' ability to congeal pooled human blood in vitro.

Autophagy and leucine promote chronological longevity and respiration proficiency during calorie restriction in yeast.

We have previously shown that autophagy is required for chronological longevity in the budding yeast Saccharomyces cerevisiae. Here we examine the requirements for autophagy during extension of chronological life span (CLS) by calorie restriction (CR). We find that autophagy is upregulated by two CR interventions that extend CLS: water wash CR and low glucose CR.
