Intracranial high-grade glioma along with cancerous growth of spine intramedullary metastasis: a good atypical business presentation together with overview of novels.
d and often supplemented to make the information more easily exploitable.We give access to our own unpublished georeferenced and genotyped records from 612 samples taken over the last 20 years in several European countries (Switzerland, Belgium, Netherlands, Spain etc.). These include two countries (Portugal and North Macedonia), for which the presence of C. pruni had not been reported before. As our specimens have been genotyped (74 sites with species A solely, 202 with species B solely and 310 with species A+B), our new data enable a better overview of the geographical distribution of the two cryptic species at the Palaearctic scale.The freshwater shrimp genus Cryphiops Dana, 1852 has a disjunct distribution in North (Mexico) and South (Brazil, Chile) America, and is composed of only six species. The current classification of genera in the Palaemonidae is controversial, based on variable morphological characters, and still far from a clear definition. Cryphiops differs from the speciose genus Macrobrachium Spence Bate, 1868 only by the absence of the hepatic spines on the carapace. Previous studies with a limited dataset suggested the necessity to link morphology and phylogeny to create an internal rearrangement in the genus to resolve the paraphyletic status. Through a molecular phylogenetic approach, the evolutionary relationships are inferred based on four (mitochondrial and nuclear) genes, among all recognized species of Cryphiops and, in combination with a taxonomic revision, a rearrangement in the systematics of the genus is suggested. The absence of hepatic spines on the carapace, the only character used to separate the genus Cryphiops, is subjective and should be considered as a homoplasy. This implies that Cryphiops and Macrobrachium are subjective synonyms and, because the latter genus is much more diverse and widely known, with several economically important species, to avoid confusion and disturbance in nomenclatural stability and keep universality, a proposal for the priority of the older synonym (Cryphiops) to be partially suppressed in favor of maintaining the prevailing use of the younger synonym (Macrobrachium) is presented. As the species of Cryphiops should be accommodated in the genus Macrobrachium, new names to replace three preoccupied specific names that, by this action, resulted to be secondary homonyms are offered.Although it is well known that both stretching and foam rolling can acutely increase the range of motion (ROM) and affect performance, the effects of a combined treatment (foam rolling and stretching) are not yet clear. Hence, the purpose of this meta-analysis was to compare the combined effect to that of stretching or foam rolling alone on both ROM and performance. We assessed the effect of a combined treatment on ROM and compared it to the effect of stretching, foam rolling, and a control condition by applying a random-effect meta-analysis. We also applied the same model to compare the effect of the combined treatment on performance. Moreover, by applying a mixed-effect model, we performed subgroup analyses with the stretching technique, type of foam rolling, tested muscles, type of task, and the order of the combined treatment. We found a significant overall effect on ROM change when comparing the combined treatment with the control condition (effect size (ES) = -0.332); however, no significant effect was found when comparing it to stretching (ES = 0.032) or foam rolling alone (ES = -0.225). click here The meta-analysis revealed no significant overall effect on performance when the combined treatment was compared to stretching alone (ES = -0.029). However, the subgroup analysis for performance revealed a superior effect for the combined treatment compared to stretching alone, but only if foam rolling was followed by stretching (ES = -0.17), and not vice versa. Athletes do not have to combine stretching with foam rolling since no additional effect was observed. However, to increase performance, the combination of foam rolling followed by stretching can lead to greater improvements.The purpose of the present study was to adapt and validate the Physical Appearance State and Trait Anxiety Scale (PASTAS) for Mexican adolescents, verifying the factor invariance by sports and non-sports practitioners. A sample of 930 Mexican adolescents (46.0% females), aged 11-15 years old, voluntarily participated in the study. A total of 415 participants regularly played sports in a club and/or regularly participated in sports competitions and 515 were non-sports practitioners. The adolescents filled out the trait version of the PASTAS questionnaire, which was previously translated and adapted for Mexican-speaking adolescents following the International Test Commission guidelines. The results of the confirmatory factor analyses showed an adequate measurement model for the original two-factor structure (e.g., GFI = 0.913; RMSEA = 0.078; CFI = 0.943). The internal consistency of the two dimensions was excellent (α and Ω = 0.92-0.93). Additionally, the results of the factorial invariance analyses showed an appropriate fit of the two-structure model (e.g., GFI = 0.96; CFI = 0.98; RMSEA = 0.04) among both sports and non-sports practitioners. The proposed trait version of the PASTAS questionnaire adapted to a Mexican-speaking population shows adequate psychometric properties among Mexican adolescents. The Mexican version of the PASTAS questionnaire supports the original two-factor structure (i.e., factor related to the body weight and factor not related to body weight) among adolescents. Additionally, the factorial invariance analyses support the equivalence of the two-factor structure among both sports and non-sports practitioners.By adopting Sport Education into the university context, this study examined how lesson content and teacher interaction contribute to university students' physical activity levels during physical education lessons. Following a continuing professional development workshop, a 10-week Sport Education season was designed collaboratively and implemented at a university, taking into account the university's facilities. This study used the momentary time sampling tool, System for Observing Fitness Instruction Time, in which eight teachers and 202 students (72% male) were videotaped in 156 lessons. The data on physical activity levels, lesson content, and teacher behavior were collected and analyzed. The student-participants engaged in an average of 38.77 (±18.78) moderate-to-vigorous physical activity (MVPA) minutes which did not meet the recommendation of 50% lesson time. Findings of hierarchical linear regression indicated that knowledge (β = 0.29) and general content (β = 0.29) contributed to the sitting physical activity while skill practices (β = 0.
