Objective: The purpose of this study was to compare the energy expenditure of a tailored, interactive genre of e-gaming ("Winds of Orbis: An Active Adventure"; Entertainment Technology Center, Carnegie Mellon, Pittsburgh, PA) ( www.activeadventuregame.com ) with that of a tethered videogame ("Dance Dance Revolution" [DDR]; Konami Digital Entertainment, El Segundo, CA) and with traditional physical education (PE) activities in meeting recommended levels of moderate- to vigorous-intensity physical activity (MVPA).
Subjects And Methods: Schoolchildren (n=104) in grades 3-8 from inner-city Washington, DC completed three randomly ordered 20-minute bouts of DDR, "Orbis," and PE. Energy expenditure was measured using accelerometry.
Results: Overall, energy expenditure was significantly greater from PE compared with "Orbis" and DDR (P<0.01). Among girls (n=58) and children with obesity (n=49), however, energy expenditure from "Orbis" and PE was similar, and both resulted in higher energy expenditure compared with DDR (P<0.01). After adjustment for sex, grade, and body mass index, we observed that among children in grades 3-5 energy expenditure from all three activities was sufficient to meet recommended intensity criteria for vigorous activity (>6 metabolic equivalents). Among children in grades 6-8, however, these vigorous-intensity criteria were met only by boys and only with PE activities.
Conclusions: In the school setting, traditional PE activities continue to work well for some children in meeting MVPA recommendations. Among special subgroups, however, e-gaming may provide a useful supplement to PE in increasing activity levels during the school day and beyond.

Thermodynamics has long been applied in predicting undiscovered microorganisms or analyzing energy flows in microbial metabolism, as well as evaluating microbial impacts on global element distributions. However, further development and refinement in this interdisciplinary field are still needed. This work endeavors to develop a whole-cycle framework integrating thermodynamics with microbiological studies, focusing on representative nitrogen-transforming microorganisms.

In this study, we investigated the synergistic potential of bacteriophage vB_SauM-515A1 ( family) and the first-line antibiotic linezolid against the methicillin-resistant strain SA0413Rev. A checkerboard assay revealed a significant synergistic effect against planktonic cells (FIC = 0.

In this study, we examined the effects of different residual feed intakes (RFIs) on nutrient digestibility and the microbiota of the digestive tract of Dexin fine-wool sheep. Fifty 70-day-old Dexin fine-wool meat lambs were selected as the experimental group and fed in a single pen for 100 days. Based on their mid-term metabolic weight, 100-day average daily weight gain and daily feed intake, the male Dexin lambs were divided into a low-RFI group (13), a mid-RFI group (18), and a high-RFI group (11).

Autophagy is a conservative process of self degradation, in which abnormal organelles, proteins and other macromolecules are encapsulated and transferred to lysosomes for subsequent degradation. It maintains the intracellular balance, and responds to cellular conditions such as hunger or stress. To date, there are mainly three types of autophagy: macroautophagy, microautophagy and chaperone-mediated autophagy.

Periphyton acts as an important primary producer in stream food webs with bottom-up grazing pressure and is also subject to effects of top-down grazing pressure. However, the underlying mechanisms of these interactions remain unclear. In this study we conducted a mesocosm experiment to explore the periphyton response to grazing pressure by the freshwater snail in relation to food quality indicated by polyunsaturated fatty acid (PUFA) biomarkers, including eicosapentaenoic acid (20:5n3) and the 22C fatty acid docosahexaenoic acid (22:6n3), which are essential for cell growth and reproduction and cannot be synthesized by most consumers of periphyton.
