Segmental Phase Angle and Body Composition Fluctuation of Elite Ski Jumpers between Summer and Winter FIS Competitions

(1) Background: The purpose of this study was to observe segmental phase angle (PhA) and body composition fluctuation of elite ski jumpers. (2) Methods: In the study, 12 professional ski jumpers took part. Body composition was estimated with segmental multi-frequency bioelectrical impedance analysis. Repeated ANOVA was used to check the parameters’ variability in time. The symmetry between the right and left side of the body was verified with the t-test for dependent samples. Pearson’s linear correlation coefficient was calculated. (3) Results: The most stable parameter was body weight. An increase in the visceral fat area was noted, the fat-free mass dropped, and significant changes were noted in the internal and external cell water parameters. Parameters connected with water between the right and left side of the body were symmetrical. Significant correlation between PhA values and body parameters with regard to fat tissue and PhA values of the legs was noticed when PhA was measured at 50 kHz. (4) Conclusions: PhA could be considered as a ski jumper body symmetry monitoring tool. The described relationship may be useful for the assessment of body fat change, which, in the case of jumpers, is crucial. Moreover, our data suggest that segmental PhA evaluation could be a good solution for ski jumpers as a confirmation if lowered body mass and low BMI are still healthy and increase the chance for longer jumps and good performance.

Presence in Lume’s Work as Temporal Enlargement and Oceanic Feeling

ABSTRACT The article combines efforts to read Lume’s aesthetic based on possible philosophical connections supported by the notion of temporal enlargement and the Freudian concept of oceanic feeling. The philosophical-conceptual methodology was used to this end. The ideas of composition, fluctuation and saturation plane, delirium, the dissolution of borders and a sense of holistic connection stood out. Presence was the articulating element of Lume’s aesthetic, which is framed by the aforementioned conceptual principles. By exposing two possible receptions, the text intends the comparison with such knowledge to add layers of expansion to the theatrical aesthetic experience, not aiming to reveal meanings, but rather to propose intelligibilities.

Draft Genome Sequences of 15 Bacterial Species Constituting the Stable Defined Intestinal Microbiota of the GM15 Gnotobiotic Mouse Model

ABSTRACT The GM15 community is a bacterial consortium used to generate a novel standardized mouse model with a simplified controlled intestinal microbiota recapitulating the specific opportunistic pathogen-free (SOPF) mouse phenotype and the potential to ensure an increased reproducibility and robustness of preclinical studies by limiting the confounding effect of microbiota composition fluctuation.

A standardized gnotobiotic mouse model harboring a minimal 15-member mouse gut microbiota recapitulates SOPF phenotype

Mus musculus is the classic mammalian model for biomedical research. Despite global efforts in standardizing breeding and experimental procedures, the undefined nature and inter-individual diversity of laboratory mouse microbiota remains a limitation. In an attempt to standardize preclinical studies, we have developed a simplified mouse microbiota composed of 15 strains from 7 of the 20 most prevalent bacterial families representative of the fecal microbiota found in specific opportunistic- and pathogen-free (SOPF) C57BL/6J animals and derived a standardized gnotobiotic mouse model called GM15. GM15 recapitulates extensively the functionalities found in C57BL/6J SOPF microbiota metagenome and GM15 animals are phenotypically similar to SOPF. They even perform better in a model of post-weaning malnutrition. The GM15 model ensures an increased reproducibility and robustness of preclinical studies by limiting the confounding effect of microbiota composition fluctuation and offers new possibilities for research focusing on how the microbiota shapes host physiology in health and diseases.
