Effects of music and video on perceived exertion during high-intensity exercise

引用

Journal of Sport and Health Science 2017年第1期6卷 81-88页

作者： Enoch C.Chow jennifer l.Etnier Department of Kinesiology University of North Carolina at GreensboroGreensboroNC 27412USA

Background: Dissociative attentional stimuli(e.g., music, video) are effective in decreasing ratings of perceived exertion(RPE) during low-tomoderate intensity exercise, but have inconsistent results during exercise at higher intensity. The purpose of this study was to assess attentional focus and RPE during high-intensity exercise as a function of being exposed to music, video, both(music and video), or a no-treatment control ***: During the first session, healthy men(n = 15) completed a maximal fitness test to determine the workload necessary for high-intensity exercise(operationalized as 125% ventilatory threshold) to be performed during subsequent sessions. On 4 subsequent days, they completed 20 min of high-intensity exercise in a no-treatment control condition or while listening to music, watching a video, or both. Attentional focus, RPE,heart rate, and distance covered were measured every 4 min during the ***: Music and video in combination resulted in significantly lower RPE across time(partial η~2= 0.36) and the size of the effect increased over time(partial η~2= 0.14). Additionally, music and video in combination resulted in a significantly more dissociative focus than the other conditions(partial η~2= 0.29).Conclusion: Music and video in combination may result in lower perceived exertion during high-intensity exercise when compared to music or video in isolation. Future research will be necessary to test if reductions in perceived exertion in response to dissociative attentional stimuli have implications for exercise adherence.

Determination of the cellulase activity distribution in Clostridium thermocellum and Caldicellulosiruptor obsidiansis cultures using a fluorescent substrate

引用

Journal of Environmental Sciences 2015年第8期27卷 212-218页

作者： jennifer l.Morrell-Falvey James G.Elkins Zhi-Wu Wang Bio Energy Science Center Biosciences Division Oak Ridge National Laboratory The Ohio State University ATI

This study took advantage of resorufin cellobioside as a fluorescent substrate to determine the distribution of cellulase activity in cellulosic biomass fermentation systems. Cellulolytic biofilms were found to express nearly four orders greater cellulase activity compared to planktonic cultures of Clostridium thermocellum and Caldicellulosiruptor obsidiansis, which can be primarily attributed to the high cell concentration and surface attachment. The formation of biofilms results in cellulases being secreted close to their substrates, which appears to be an energetically favorable stategy for insoluble substrate utilization. For the same reason,cellulases should be closely associated with the surfaces of suspended cell in soluble substrate-fed culture, which has been verified with cellobiose-fed cultures of C. thermocellum and C. obsidiansis. This study addressed the importance of cellulase activity distribution in cellulosic biomass fermentation, and provided theoretical foundation for the leading role of biofilm in cellulose degradation. System optimization and reactor designs that promote biofilm formation in cellulosic biomass hydrolysis may promise an improved cellulosic biofuel process.

PARP inhibitors as precision medicine for cancer treatment

Personalized or precision medicine is an emerging treatment approach tailored to individuals or certain groups of patients based on their unique characteristics. These types of therapies guided by biomarkers tend to be more effective than traditional approaches, especially in cancer. The inhibitor against poly(ADP-ribose) polymerase(PARP), olaparib(lynparza, Astra Zeneca), which was approved by the US Food and Drug Administration(FDA) in 2014, demonstrated efficacy specifically for ovarian cancer patients harboring mutations in BRCA genes, which encode proteins in DNA double-strand break ***, the response to PARP inhibitors has been less encouraging in other cancer types that also carry defects in the BRCA genes. Thus, furthering our understanding of the underlying mechanism of PARP inhibitors and resistance is critical to improve their efficacy. In this review, we summarize the results of preclinical studies and the clinical application of PARP inhibitors, and discuss the future direction of PARP inhibitors as a potential marker-guided personalized medicine for cancer treatment.

Activation of phagocytosis by immune checkpoint blockade

引用

Frontiers of Medicine 2018年第4期12卷 473-480页

作者： Chia-Wei li Yun-Ju lai jennifer l. Hsu Mien-Chie Hung Department of Molecular and Cellular Oncology The University of Texas MD Anderson Cancer Center Houston TX 77030 USA Department of Neurology McGovern Medical School The University of Texas Health Science Center at Houston Houston TX 77030 USA

Inhibition of macrophage-mediated phagocytosis has emerged as an essential mechanism for tumor immune evasion. One mechanism inhibiting the innate response is the presence of the macrophage inhibitory molecule, signal regulatory protein-a （SIRPa）, on tumor-associated macrophages （TAMs） and its cognate ligand cluster of differentiation 47 （CD47） on tumor cells in the tumor microenvironment. On the basis of a recently discovered programmed death protein 1 （PD-1） in TAMs, we discuss the potential inhibitory receptors that possess new functions beyond T cell exhaustion in this review. As more and more immune receptors are found to be expressed on TAMs, the corresponding therapies may also stimulate macrophages for phagocytosis and thereby provide extra anti-tumor benefits in cancer therapy. Therefore, identification of biomarkers and combinatorial therapeutic strategies, have the potential to improve the efficacy and safety profiles of current immunotherapies.

Background: Selective serotonergic reuptake inhibitors(SSRIs) are first-line pharmacologic treatments for patients with posttraumatic stress disorder(PTSD), but must be given over extended period of time before the onset of action. The use of SSRIs in PTSD patients with mild traumatic brain injury(m TBI) is problematic since SSRIs could exacerbate post-concussion syndrome(PCS) symptoms. VA/DOD guidelines identify trauma-focused psychotherapy as the best evidence-based treatment for PTSD, but overall effectiveness is limited by reduced levels of patient engagement and retention. A previous study from this research group suggested that quetiapine monotherapy, but not risperidone or valproate, could increase engagement in trauma-focused ***: We report the study protocol of a pilot study funded under the South-Central Mental Illness Research, Education, and Clinical Center pilot study program from the U.S. Department of Veterans Affairs. This randomized, open-label study was designed to evaluate the feasibility of completing a randomized trial of quetiapine vs. treatment as usual to promote patient engagement in PTSD patients with a history of m ***: We expect that the success of this ongoing study should provide us with the preliminary data necessary to design a full-scale randomized trial. Positive efficacy results in a full-scale trial should inform new VA guidelines for clinical practice by showing that quetiapine-related improvements in patient engagement and retention may be the most effective approach to assure that VA resources achieve the best possible outcome for *** registration: NCT04280965.
