show that homologous muscle functions are mediated through common oscillatory input that extends over alpha, beta, and gamma frequencies with different synchronization patterns at different movement periods.Skillful manipulation requires forming memories of object dynamics, linking applied force to motion. Although it has been assumed that such memories are linked to objects, a recent study showed that people can form separate memories when these are linked to different controlled points on an object (Heald JB, Ingram JN, Flanagan JR, Wolpert DM. Nat Hum Behav 2 300-311, 2018). In that study, participants controlled the handle of a robotic device to move a virtual bar with circles (control points) on the left and right sides. Participants were instructed to move either the left or right control point to a target on the left or right, respectively, such that the required movement was constant. When these control points were paired with opposing force fields, adaptation was observed. In this previous study, both the controlled point and the target changed between contexts. To assess which of these factors is critical for learning, here, we used a similar paradigm but with a bar that automatically rotated as it was moved. In the first experiment, the bar rotated, such that the left and right control points moved to a common target. In the second experiment, the bar rotated such that a single control point moved to a target located on either the left or right. In both experiments, participants were able to learn opposing force fields applied in the two contexts. We conclude that separate memories of dynamics can be formed for different "contact goals," involving a unique combination of the controlled point on an object and the target location this point "contacts."NEW & NOTEWORTHY Skilled manipulation requires forming memories of object dynamics, previously assumed to be associated with entire objects. However, we recently demonstrated that people can form multiple motor memories when explicitly instructed to move different locations on an object to different targets. Here, we show that separate motor memories can be learned for different contact goals, which involve a unique combination of a control point and target.The Extended Bootstrap (EB) assessment approach was developed for the examination of relationships of Type I error, power, sample size (n), and effect size (ES) for statistical tests of ecological data. The EB approach was applied to univariate and multivariate statistical analyses of a large data set collected from an ongoing, multiple stressor bioassessment study of watersheds in the Central Valley, San Francisco, and Central Coast areas of California. Benthic metrics were created that either increased or decreased monotonically with stress (toxicants or metrics indicative of habitat quality). Type I errors were stable for all statistical tests that were evaluated. The relationships between n and ES displayed patterns of "diminishing returns" for all statistical tests i.e. an increasingly larger n was required to detect decreasingly smaller ES. Nonetheless, the n's collected across the watersheds and within a selected watershed were sufficient to detect even small correlations between representative benthic metrics and potential stressors with high power. The power and robustness of a novel method using EB and previously described statistical techniques designed to address multicollinearity were shown to approach those of simpler univariate regressions. Potential applications of the EB approach for experimental design, data assessment and interpretation, and hypothesis testing are discussed.Fish cell lines, collectively referred to as the fish invitrome, are useful diagnostic tools to study radiation impacts on aquatic health and elucidate radiation mechanisms in fish. This paper will highlight the advantages, discuss the challenges, and propose possible future directions for uses of the fish invitrome in the field of environmental radiobiology. The fish invitrome contains at least 714 fish cell lines. However, only a few of these cell lines have been used to study radiation biology in fish and they represent only 10 fish species. The fish invitrome is clearly not yet explored for its full potential in radiation biology. Evidence suggests that they are useful and, in some cases, irreplaceable in making underlying theories and fundamental concepts in radiation responses in fish. The debate of whether environmental radiation is harmful, presents risks, has no effect on health, or is beneficial is on-going and is one that fish cell lines can help address in a time-effective fashion. Any information obtained with fish cell lines is useful in the framework of environment radiation risk assessments. Radiation threats to aquatic health will continue due to the very likely rise of nuclear energy and medicine in the future. The fish invitrome, in theory, lives forever and can meet new challenges at any given time to provide diagnostic risk analyses pertaining to aquatic health and environmental radiation protection.This study plans to investigate the effects of long-noncoding RNA MACC1-AS1 on glioma cells and its mechanism at metabolic plasticity angle. The MACC1-AS1 level was identified both in glioma tissues and in cells. Then the effects of MACC1-AS1 abnormal level on cell viability, apoptosis, the expression of apoptosis associated protein, glucose metabolism and redox status were measured in A172 and U251 cells by different methods. Furthermore, the interaction of MACC1-AS1 and MACC1 in glioma cells was investigated and the role of AMPK pathway was specifically examined. Our results demonstrated that MACC1-AS1 level was high in glioma tissues and cells, and MACC1-AS1 overexpression was closely associated with poor prognosis of glioma. FRAX597 in vivo Notably, under glucose deprivation, the MACC1-AS1 level was significantly increased, and overexpression of MACC1-AS1 increased cell viability but inhibited apoptosis. Also, MACC1-AS1 overexpression obviously increased the levels of GLUT1, HK2, G6PD, MCT1, ATP, lactate and NAPDH as well as promoted the activities of HK2 and LDHA, while reduced ROS level and the ratio of NADP+/NAPDH. In particular, the effects of proliferation, apoptosis and metabolic plasticity of glioma cells caused by MACC1-AS1 overexpression were achieved by positively regulating MACC1, and MACC1-AS1 promoted MACC1 expression via the AMPK pathway. In conclusions, the MACC1-AS1/MACC1 axis exertes the tumor-promoting effect by regulating glucose metabolism and redox homeostasis in glioma cells by activating the AMPK signals.
