Diaphragmatic dysfunction is suggested to play an important role in the development of PPCs and diaphragm echodensity can be used as an indicator of diaphragm function. This study aimed to determine whether diaphragm echodensity could predict the occurrence of PPCs in patients after major abdominal surgery. Methods Diaphragm ultrasound images of patients after major abdominal surgery were...

Growth with Commensal Streptococci Alters Streptococcus mutans Behaviors

M. Rose, N. Wilson, E. Williams, H. Letner, R. Bettinger, A. Bouchendouka, J. Batagower & J.R. Kaspar
As oral bacteria grow and persist within biofilms attached to the tooth’s surface, they interact with other species to form synergistic or antagonistic exchanges that govern homeostasis for the overall population. One example are the interactions between the cariogenic species Streptococcus mutans and oral commensal streptococci. Previously, we showed that the cell–cell signaling pathways of S. mutans were inhibited during coculture with other oral streptococci species, leading us to posit that the S. mutans transcriptome...

Unambiguous spectral characterization on triplet energy transfer from quantum dots mediated by hole transfer competing with other carrier dynamics

Lei Wang, Gaoyuan Yang, Boyu Zhang, Xin Zhang, Dezheng Liu, Ying Liang & Guijie Liang
Triplet generation by QDs-sensitized molecules emerges great potential in many applications. However, the mechanism of triplet energy transfer (TET) is still fuzzy especially due to complicated energy level alignment of QDs and molecules or trap states in QDs. Here, CdSe QDs and 5-tetracene carboxylic acid (TCA) molecules are selected as the triplet donor and acceptor, respectively, to form a TET system. By tuning the band gap of CdSe, the CdSe-TCA complex is exactly designed to...

Abstract Clinical translation from bench to bedside often remains challenging even despite promising preclinical evidence. Among many drivers like biological complexity or poorly understood disease pathology, preclinical evidence often lacks desired robustness. Reasons include low sample sizes, selective reporting, publication bias, and consequently inflated effect sizes. In this context, there is growing consensus that confirmatory multicenter studies -by weeding out false positives- represent an important step in strengthening and generating preclinical evidence before moving on...

Yasmine Sommerer, Olena Ohlei, Valerija Dobricic, Derek H. Oakley, Tanja Wesse, Sanaz Sedghpour Sabet, Ilja Demuth, Andre Franke, Bradley T. Hyman, Christina M. Lill & Lars Bertram
Abstract Epigenome-wide association studies (EWAS) assessing the link between DNA methylation (DNAm) and phenotypes related to structural brain measures, cognitive function, and neurodegenerative diseases are becoming increasingly more popular. Due to the inaccessibility of brain tissue in humans, several studies use peripheral tissues such as blood, buccal swabs, and saliva as surrogates. To aid the functional interpretation of EWAS findings in such settings, there is a need to assess the correlation of DNAm variability across...

Harmonic error observation of permanent magnet synchronous motor and its angle lag compensation method

Lei Wang, Yukun Han & Guoxu Zhao
During the permanent magnet synchronous motor operation, the inherent back-EMF output voltage harmonics of the permanent magnet synchronous motor shows the high harmonic noise signal, which is not conducive to the high precision control system. The harmonic error compensation method based on feedforward compensation is adopted to solve this problem and improve the system response characteristics and control accuracy. Firstly, in this paper, the torque harmonic error of a 12-pole 18-slot permanent magnet synchronous motor...
