For quantitative real time PCR data, the effect of treatment (CTR versus LES), the effect of ErbB2 over-expression (BALB/c versus BALB-neuT) and the interaction between the two factors (treatment and ErbB2 over-expression) were analyzed by two-way ANOVA test. Analysis of all ErbBs showed highly significant main effects of treatment (CTR versus LES) while the effect of ErbB2 over-expression (BALB/c versus BALB-neuT) and the interaction between the two factors (treatment and ErbB2 over-expression) was not significant. Analysis of NRG1 showed highly significant main effects of treatment (CTR versus LES) for all NRG1 isoforms analyzed; the effect of ErbB2 over-expression (BALB/c versus BALB-neuT) and the interaction between the two factors (treatment and ErbB2 over-expression) were highly significant only for NRG1 alpha, beta, type I/II.

Swimming behaviors of four species of cnidarian hydromedusae (Aequorea victoria, Mitrocoma cellularia, Stomotoca atra, Aglantha digitale) exposed to two flow conditions in a laboratory turbulence generator - still water and turbulent (ε ~10-7 m2 s-3) were examined.

A two-way ANOVA was used to test for significant effects of species, flow level (still and turbulent) and their interaction on swimming behavior parameters, including depth in the tank, observed speed, acceleration, NGDR, and time spent swimming. Raw data that did not meet the assumption of normality were square root transformed. Proportion data (NGDR, and time spent swimming) that did not meet the assumption of normality were arcsine square root transformed, which is appropriate for proportion data (Zar, 1999).

This dataset examines the complexity of network structures in professional and collegiate women’s soccer teams using directed network analysis based on tri-axial acceleration data. The study involved one professional team and one university-level team, with data collected from matches during their respective seasons. Directed network analysis identified dyads and triads, representing cooperative interactions among players, while movement entropy quantified the influence of individual movements within the team. Network diversity, defined as the variability in activation probabilities of dyads and triads, was calculated to evaluate the tactical dynamics and cooperative behaviors of the teams. Data were collected using GNSS devices equipped with tri-axial accelerometers, ensuring precise measurement of movement intensity. The findings provide insights into the structural and functional differences in team coordination between professional and collegiate levels. The dataset is anonymized an..., Participants Prior to participant recruitment, we calculated the minimum required number of matches using G*Power 3.1.9.4 (Heinrich Heine Universität Düsseldorf, Germany). This study employs a two-way analysis of variance (ANOVA) to primarily examine the interaction effects between the period of the match (the first half and second half of the match) and three team groups (professional teams during the first half of the season, professional teams during the second half of the season, and collegiate teams). Thus, the calculation for the F-test with ANOVA was conducted a priori, given an effect size of 0.40, an α error probability of 0.05, a power of 0.80, and a numerator df of 2 with six groups. The effect size (0.40) for this analysis was set based on findings from a previous study that examined changes in team coordination states during matches and reported a large effect size (η² = 0.240 to 0.263) for differences influenced by the level of the opposing team.

Dataset Overview

This dataset investigates the complexity of network structures in professional and collegiate women’s soccer teams, focusing on cooperative interactions and tactical dynamics. Data were collected during matches using GNSS devices equipped with tri-axial accelerometers, providing precise measurements of player movements and interactions.

Data Content

The dataset includes:

1. Player Movement Data: Tri-axial acceleration data recorded at 10 Hz for all players during each match. Data capture spans from match entry to exit, with segmentation into 45-minute halves. Stoppage time is excluded, and substitutions are handled by segmenting data accordingly.
2. Network Analysis Results: Quantitative results of directed network analysis, includ...

This record contains raw data related to article "Robotic surgery, video-assisted thoracic surgery, and open surgery for early stage lung cancer comparison of costs and outcomes at a single institute"

Background:

Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC).

Methods:

We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values <0.05 were considered significant.

Results:

Twenty-three patients were treated by robot, 41 by VATS, and 39 by open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (P<0.001). Significantly more lymph node stations were removed (P<0.001), and median length of stay was shorter (4, 5 and 6 days, respectively; P<0.001) in the robotic than VATS and open groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches.

Discussion:

Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.
