Traditional assessment (e.g., checklists, videotaping) for surgical proficiency may lead to subjectivity and does not predict performance in the clinical setting. Hand motion analysis is evolving as an objective tool for grading technical dexterity; however, most devices accompany with technical limitations or discomfort. We purpose the use of flexible wearable sensors to evaluate the kinematics of surgical proficiency. Surgeons were recruited and performed a vascular anastomosis task in a single institution. A modified objective structured assessment of technical skills (mOSATS) was used for technical qualification. Flexible wearable sensors (BioStamp RCTM, mc10 Inc., Lexington, MA) were placed on the dorsum of the dominant hand (DH) and nondominant hand (nDH) to measure kinematic parameters path length (T ), mean (V ) and peak (V ) velocity, number of hand movements (N ), ratio of DH to nDH movements (rMov), and time of task (tTask) and further compared with the mOSATS score. Participants were categorized as experts (n=12) and novices (n=8) based on a cutoff mean mOSATS score. Significant differences for tTask (P=0.02), rMov (P=0.07), DH T (P=0.04), V (P=0.07), V (P=0.04), and nDH N (P=0.02) were in favor of the experts. Overall, mOSATS had significant correlation with tTask (r=-0.69, P=0.001), N of DH (r=-0.44, P=0.047) and nDH (r=-0.66, P=0.001), and rMov (r=0.52, P=0.017). Hand motion analysis evaluated by flexible wearable sensors is feasible and informative. Experts utilize coordinated two-handed motion, whereas novices perform one-handed tasks in a hastily jerky manner. These tendencies create opportunity for improvement in surgical proficiency among trainees.Hand motion analysis evaluated by flexible wearable sensors is feasible and informative. 5-Ethynyluridine mouse Experts utilize coordinated two-handed motion, whereas novices perform one-handed tasks in a hastily jerky manner.

The aim of this work was to chemically characterize three Geoffroea decorticans extracts and determine their capacity to modulate the wnt/β-catenin pathway. This signaling pathway plays a key role in embryonic development but its overactivation leads to cancer cell growth. Phytochemical analysis of extracts showed presence of major classes of phytochemicals. Gas chromatography-mass spectrometry results revealed the presence of acids, esters and furanic compounds. Using Xenopus embryos as in vivo model organisms, we found that the extracts modulated dorso-ventral axis formation and rescued hyperdorsalized phenotypes produced by LiCl treatment. In agreement with these findings, Geoffroea decorticans extracts decreased β-catenin levels and suppressed the expression of wnt target genes such as xnr3 and chordin, thus demonstrating an inhibitory regulation of the wnt/β-catenin signaling pathway. All these results support a new role for Geoffroea decorticans fruit derivatives with possible anti-carcinogenic actions.Extracellular vesicles (EVs) are lipid bilayer particles that are released by various cells and provide a real-time snapshot of the state of these cells in tissue in a noninvasive manner. EVs contain components, including mRNA, miRNAs, proteins, and metabolites. Therefore, EVs hold promise for the discovery of liquid biopsy-based biomarkers for disease diagnosis. In the present study, metabolome analysis of urine EVs in rats with kidney injury caused by cisplatin and puromycin aminonucleoside was performed using liquid chromatography/mass spectrometry to identify candidate biomarkers that reflect the type and extent of injury in drug-induced nephrotoxicity. A total of 396 metabolites were detected in urine EVs, of which 65 were identified as potential biomarkers in urine EVs of drug-induced nephrotoxicity. Pathway analysis revealed that these metabolites may reflect changes occurring within damaged cells during kidney injury, suggesting that metabolomics of urine EVs could be a useful informative tool.Studies have demonstrated that stochastic configuration networks (SCNs) have good potential for rapid data modeling because of their sufficient adequate learning power, which is theoretically guaranteed. Empirical studies have verified that the learner models produced by SCNs can usually achieve favorable test performance in practice but more in-depth theoretical analysis of their generalization power would be useful for constructing SCN-based ensemble models with enhanced generalization capacities. In particular, given a collection of independently developed SCN-based learner models, it is useful to select certain base learners that can potentially obtain preferable test results rather than considering all of the base models together, before simply taking their average in order to build an effective ensemble model. In this study, we propose a novel framework for building SCN ensembles by exploring key factors that might potentially affect the generalization performance of the base model. Under a mild assumption, we provide a comprehensive theoretical framework for examining a learner model's generalization error, as well as formulating a novel indicator that contains measurement information for the training errors, output weights, and a hidden layer output matrix, which can be used by our proposed algorithm to find a subset of appropriate base models from a pool of randomized learner models. A toy example of one-dimensional function approximation, a case study for developing a predictive model for forecasting student learning performance, and two large-scale data sets were used in our experiments. The experimental results indicate that our proposed method has some remarkable advantages for building ensemble models.
