Abstract	Physical activity results in oxidative stress, as evidenced by the increased production of reactive oxygen, nitrogen species, and inflammatory mediators. The management of these components is instrumental for antioxidant adaptation to exercise and post-exercise recovery. Therefore, the present report aims to study the antioxidant response to two types of exercise (a 2000 m run and a burpee test) in healthy volunteers after a long period of inactivity (1-2 months). Antioxidant enzyme activities and oxidative stress markers (protein carbonyls and malondialdehyde content) were measured in neutrophils, peripheral blood mononuclear cells, and plasma. These parameters were determined under basal conditions and immediately post-exercise. Compared to those in basal state, neutrophil superoxide dismutase (28.3 vs. 22.9 pkat/10

Abstract	Altitude exposure may suppress appetite and hence provide a viable weight-loss strategy. While changes in food intake and availability as well as physical activity may contribute to altered appetite at altitude, herein we aimed to investigate the isolated effects of hypobaric hypoxia on appetite regulation and sensation.

Abstract	The 800-m (m) run is part of Physical Education classes in Cameroon, after which arrhythmias may occur during recovery. Hence, this study aimed at determining relationship between 800-m run loads on cardiac autonomic recovery among school adolescents.Forty-two male adolescents (aged [17 ± 1] years) performed 800-m. Post-exercise heart rate variability (HRV) was recorded during 5-min (min) (HRV5-min) and 15-min (HRV15-min) in time: Standard deviation of normal to normal (SDNN); Root mean square of successive differences (RMSSD) and frequency domain (LH: Low frequency, HF: High frequency, TP: Total power). Rating of Perceived Exertion (RPE) and blood lactate concentration (BLa) were measured after exercise. In HRV5-min, RPE was associated with SDNN (r = −0.44, p < 0.01) and RMSSD (r = −0.38, p < 0.05). BLa was correlated with SDNN (r = −0.38, p < 0.05) and RMSSD (r = −0.56, p < 0.001) in the time-domain, LF (r = −0.64, p < 0.001), HF (r = −0.58, p < 0.001) and TP (r = −0.61, p < 0.001) in frequency-domain. Moreover, RPE was correlated with LF (r = −0.44, p < 0.01), TP (r = −0.49, p < 0.01) while exercise duration with HF (r = −0.38, p < 0.05). In HRV15-min, BLa was correlated with RMSSD (r = −0.53, p < 0.001) and SDNN (r = −0.68, p < 0.001). RPE was negatively correlated SDNN (r = −0.53, p < 0.01) and RMSSD (r = −0.44, p < 0.01). BLa was associated with HF (r = −0.55, p < 0.001), TP (r = −0.50, p < 0.01) and RPE with LF (r = −0.51, p < 0.01), HF (r = −0.50, p < 0.01), TP (r = −0.49, p < 0.01). In addition, exercise duration was negatively linked to HF (r = −0.36, p < 0.05). This study outlined that in untrained adolescents an increase of 800-m loads is associated with a slow vagal indexes of HRV during the recovery.

Abstract	Fbw7 is a tumor suppressor often deleted or mutated in human cancers. It serves as the substrate-recruiting subunit of a SCF ubiquitin ligase that targets numerous critical proteins for degradation, including oncoproteins and master transcription factors. Cyclin E was the first identified substrate of the SCFFbw7 ubiquitin ligase. In human cancers bearing FBXW7-gene mutations, deregulation of cyclin E turnover leads to its aberrant expression in mitosis. We investigated Fbw7 regulation in Xenopus eggs, which, although arrested in a mitotic-like phase, naturally express high levels of cyclin E. Here, we report that Fbw7α, the only Fbw7 isoform detected in eggs, is phosphorylated by PKC (protein kinase C) at a key residue (S18) in a manner coincident with Fbw7α inactivation. We show that this PKC-dependent phosphorylation and inactivation of Fbw7α also occurs in mitosis during human somatic cell cycles, and importantly is critical for Fbw7α stabilization itself upon nuclear envelope breakdown. Finally, we provide evidence that S18 phosphorylation, which lies within the intrinsically disordered N-terminal region specific to the α-isoform reduces the capacity of Fbw7α to dimerize and to bind cyclin E. Together, these findings implicate PKC in an evolutionarily-conserved pathway that aims to protect Fbw7α from degradation by keeping it transiently in a resting, inactive state.

Abstract	Exercise intensity usually correlates with increased oxidative stress and enhanced cytokine production. However, it is unknown if all types of exercise that induce muscle damage can cause a parallel response in the oxidation balance and cytokine production. To this end, the effect of a 2000-m running test in a group of volunteers that regularly train in aerobic routines was studied. Different circulating parameters were measured, oxidative stress markers (protein carbonyls and malondialdehyde), antioxidant enzyme activity, and cytokine levels in plasma as well as in the main circulating cells of blood samples obtained in basal conditions and after test execution. As a result, the test caused muscle damage evidenced by an increase in circulating creatine kinase and myoglobin. This was accompanied by an increase in protein carbonyls in plasma and peripheral blood mononuclear cells. Activities of antioxidant enzymes (catalase, glutathione peroxidase and reductase, superoxide dismutase) were elevated in peripheral blood mononuclear cells, neutrophils, and erythrocytes after the test. Regarding cytokine production, interleukin-6, interleukin-8, interleukin-10, and tumor necrosis factor-α exhibited no significant changes after the test. Results suggest that this short but intense running exercise (2000 m) can induce muscle damage and elicit a good balance between oxidant/antioxidant responses with no changes in the circulating concentration of pro-inflammatory cytokines.

Abstract	Objectives: Our primary objective was to examine the distribution of 3-m usual walk, five repeated chair stands, and three static balance stance performances among age and gender subgroups of adults at least 65 years in two national data sets. We secondarily determined whether demographic-function associations varied across data sets, birth cohorts, or models incorporating data from those "unable to do" tasks. Methods: Two nationally representative data sets were used to generate survey weight-adjusted performance distributions: the 2015-2016 National Social Life Health and Aging Project and the 2016 National Health and Aging Trends Study. We then regressed walk and chair stand performance on age, gender, and race/ethnicity, examining differences across data sets, birth cohorts (1920-1947, 1948-1965), and before/after incorporating the "unable to do" performers. Results: Findings confirmed the gradual decline in function with age and allowed estimation of "relative" performance within age/gender subgroups. Data set distribution differences were noted, possibly due to recruitment, eligibility, and protocol variations. Demographic associations were similar across data sets but generally weaker among the 1948-1965 cohort and in models including the sizable "unable to do" group. Discussion: We present the largest, most current Short Physical Performance Battery reference data in U.S. adults aged 65 or older. Findings support standardization of administration protocols in research and clinical care and differentiating absolute from relative performance.
