Starvation resistance is associated with developmentally specified changes in sleep, feeding and metabolic rate RESEARCH ARTICLE
Elizabeth B. Brown, Melissa E. Slocumb, Milan Szuperak, Arianna Kerbs, Allen G. Gibbs, Matthew S. Kayser, and Alex C. Keene Food shortage represents a primary challenge to survival, and animals have adapted diverse developmental, physiological and behavioral strategies to survive when food becomes unavailable. Starvation resistance is strongly influenced by ecological and evolutionary history, yet the genetic basis for the evolution of starvation resistance remains poorly understood. The fruit fly Drosophila melanogaster provides a powerful model for leveraging experimental evolution to investigate traits associated with starvation resistance. While control populations only live a few days without food, selection for starvation resistance results in populations that can survive weeks. We have previously shown that selection for starvation resistance results in increased sleep and reduced feeding in adult flies. Here, we investigate the ontogeny of starvation resistance-associated behavioral and metabolic phenotypes in these experimentally selected flies. We found that selection for starvation resistance resulted in delayed development and a reduction in metabolic rate in larvae that persisted into adulthood, suggesting that these traits may allow for the accumulation of energy stores and an increase in body size within these selected populations. In addition, we found that larval sleep was largely unaffected by starvation selection and that feeding increased during the late ...

Conclusions/Implications for Practice Sleep quality in Chinese nurses is influenced directly and indirectly by various modifiable work-related factors. Interventions such as adjusting work shifts and reducing job burdens should be prioritized by administrative staff to ensure the sleep quality and clinical performance of Chinese nurses and to subsequently improve nursing care quality.
ConclusionDISE induced significant revision of the location and change in treatment of obstruction sites in children with OSAHS. Systematic implementation, especially in type-I OSAHS, would allow more precise pre-therapeutic classification and treatment adapted to actual airway obstruction.
TUESDAY, Sept. 17, 2019 -- Now that children are back in school, it's important to make sure they get enough shut-eye, sleep experts say. " No matter the age, children report improved alertness, energy, mood and physical well-being when enjoying...
This study aimed to investigate whether aromatherapy (inhalation and massage) could affect levels of stress, blood glucose, fatigue, and sleep quality in middle-aged prediabetic women.MethodsThis was a randomized controlled trial. In this study, prediabetic middle-aged women, aged 40–65-years old, with a fasting blood glucose or HbA1c level of 100 mg/dL–126 mg/dL or 5.5–6.4%, respectively, were included. The experimental treatment consisted of direct inhalation of aroma essential oil and self-massage with 3% massage oil for two weeks, as prescribed by an international aromatherapist. To dete...
