Abstract Background Ribosomal biogenesis and ribosomal proteins have attracted attention in the context of tumor biology in recent years. Instead of being mere translational machineries, ribosomes might play an active role in tumor initiation and progression. Despite its importance, regulation of ribosomal biogenesis is still not completely understood. Methods Using Gene Set Enrichment Analysis of RNA sequencing and proteomical mass spectrometry data in breast cancer cells expressing Krüppel-like factor 7 (KLF7), we identified processes altered...

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...

Association of sex steroid hormones and new bone formation rate after iliac onlay grafting: a prospective clinical pilot study

Victoria Constanze Landwehr, Tobias Fretwurst, Julia Heinen, Kirstin Vach, Katja Nelson, Susanne Nahles & Gerhard Iglhaut
Abstract Purpose The present prospective study evaluates the association between new bone formation rate in the iliac onlay graft and sex steroid hormone serum levels. Methods A total of 15 partially or completely edentulous postmenopausal females and 9 males with less than 5 mm height of the remaining alveolar bone underwent iliac onlay grafting followed by dental implant placement using a two-stage approach. Sex hormone binding globulin and 17β-estradiol serum levels were investigated by electrochemiluminescence...

Health and social care of home-dwelling frail older adults in Switzerland: a mixed methods study

Abstract Background Home-dwelling frail older adults are often faced with multimorbidity and complex care needs, requiring health and social care systems that support frail older adults to age in place. The objective of this paper was to investigate the types of formal health and social care as well as informal care and social support used by home-dwelling frail older adults; whether they perceive their support as sufficient; and their experience with and preferences for care...

Light as quantum back-action nullifying meter

Sankar Davuluri & Yong Li
We propose a new method to overcome quantum back-action in a measurement process using oscillators. An optical oscillator is used as a meter to measure the parameters of another open oscillator. The optical oscillator is synthesized such that the optical restoring force counters any perturbations induced by the quantum back-action phenomena. As a result, it is shown that the quantum back-action in continuous measurement is suppressed in the low frequency regime i.e., for frequencies much...

Experimental investigation on the pre-holed screw-drilling riveting process for joining dissimilar lightweight sheets

Zhiyong Li, Zhiyong Wang, Yong Li & Shanling Han
The use of lightweight sheets such as carbon fiber reinforced composites (CFRP), magnesium alloys, and aluminum alloys is of great significance to realize the lightweight of automobiles. However, the differences between the sheets make the joining processes of dissimilar sheets a great challenge. A pre-holed screw-drilling riveting (PH-SDR) process is proposed based on a study of existing joining processes, the rivet with threads is riveted into the sheets by rotating, and the effective joining between...

Fabrication and application of free-standing fiber based on blue phase liquid crystal

Yong Li, Zhen Yin & Dan Luo
The application of blue-phase liquid crystals (BPLCs) in optical control devices has been widely studied due to their fast response characteristics. However, the fabrication of free-standing BPLC fiber with emerging functionalities is challenging. Here, we demonstrates a free-standing fiber based on BPLC with excellent stability, flexibility and multifunction. The multi-mode fiber (MMF) end face is etched by the etching agent of buffered oxide etch (BOE), which can be fixedly connected with the free-standing BPLC fiber...

Hand hygiene improvement of individual healthcare workers: results of the multicentre PROHIBIT study

Tjallie van der Kooi, Hugo Sax, Hajo Grundmann, Didier Pittet, Sabine de Greeff, Jaap van Dissel, Lauren Clack, Albert W. Wu, Judith Davitt, Sofia Kostourou, Alison Maguinness, Anna Michalik, Viorica Nedelcu, Márta Patyi, Janja Perme Hajdinjak, Milena Prosen, David Tellez, Éva Varga, Fani Veini, Mirosław Ziętkiewicz & Walter Zingg
Abstract Background Traditionally, hand hygiene (HH) interventions do not identify the observed healthcare workers (HWCs) and therefore, reflect HH compliance only at population level. Intensive care units (ICUs) in seven European hospitals participating in the “Prevention of Hospital Infections by Intervention and Training” (PROHIBIT) study provided individual HH compliance levels. We analysed these to understand the determinants and dynamics of individual change in relation to the overall intervention effect. Methods We included HCWs who contributed...
