Evaluation of an inertial measurement unit-based approach for determining centre-of-mass movement during non-seated cycling.

J Biomech 2021 Apr 19;126:110441. Epub 2021 Apr 19.

Centre for Sensorimotor Performance School of Human Movement and Nutrition Sciences, The University of Queensland, St Lucia, Queensland, Australia.

Instantaneous crank power does not equal total joint power if a rider's centre of mass (CoM) gains and loses mechanical energy. Thus, estimating CoM motion and the associated energy changes can provide valuable information about the mechanics of cycling. To date, an accurate and precise method for tracking CoM motion during outdoor cycling has not been validated. Read More

Lactate and glutamine support NADPH generation in cancer cells under glucose deprived conditions.

Redox Biol 2021 Jul 11;46:102065. Epub 2021 Jul 11.

Cancer Institute (Key Laboratory for Cancer Intervention and Prevention, China National Ministry of Education, Zhejiang Provincial Key Laboratory of Molecular Biology in Medical Sciences), The Second Affiliated Hospital, Zhejiang University School of Medicine, 310009, Hangzhou, Zhejiang, China. Electronic address:

Although glucose, through pentose phosphate pathway (PPP), is the main source to generate NADPH, solid tumors are often deprived of glucose, hence alternative metabolic pathways to maintain NADPH homeostasis in cancer cells are required. Here, we report that lactate and glutamine support NADPH production via isocitrate dehydrogenase 1 (IDH1) and malic enzyme 1 (ME1), respectively, under glucose-deprived conditions. Isotopic tracing demonstrates that lactate participates in the formation of isocitrate. Read More

Prev Med 2021 Jul 19:106721. Epub 2021 Jul 19.

Department of Oncology, Dell Medical School, University of Texas at Austin, Austin, TX, USA.

To identify potentially modifiable risk-factors in the age-related disablement process, we examined the association between change in mobility limitations and multimorbidity and how dietary quality moderates this association. Information from 3320 adults aged 65 and older in 2012 was drawn from the Health and Retirement Study and the Health Care and Nutrition Study. Mobility limitations reported in 2012 and change in mobility limitations from 2012 to 2014 were regressed on multimorbidity measured as number of chronic conditions in 2012, dietary quality measured in 2013 using the Alternative Healthy Eating Index-2010 (AHEI-2010), and their interaction term using Poisson regression.
