Prevalence and resistance characteristics of multidrug-resistant isolated from the respiratory tracts of hospitalized children in Shenzhen, China.

Background: PCV13 introduction in China has led to a significant reduction of vaccine serotype . However, non-vaccine serotypes with highly resistance and invasiveness were often reported in the post-pneumococcal conjugate vaccine era and there was regional differences.

Methods: A total of 669 strains were collected from the respiratory tracts of hospitalized children at Shenzhen Children's Hospital in 2021 and 2022.

Efficacy of acupoint application in patients with overactive bladder: A randomized, placebo-controlled pilot trial.

Objective: Conventional treatments for alleviating the symptoms of Overactive bladder (OAB) have been reported to have limited efficacy and a high rate of side effects. Traditional Chinese medicine (TCM) has been used in Asia countries because of its low side effects and being easy to operate. To confirm the efficacy of acupoint application treatment for alleviating OAB symptoms, a randomized and placebo-controlled pilot trial was conducted in this study.

Effects of Mobile Mindfulness Meditation on the Mental Health of University Students: Systematic Review and Meta-analysis.

Background: Mobile mindfulness meditation (MMM) is a mindfulness meditation intervention implemented using mobile devices such as smartphones and apps. MMM has been used to help manage the mental health of university students.

Objective: This study aims to evaluate the effectiveness of MMM on the mental health of university students in the areas of stress, anxiety, depression, mindfulness, well-being, and resilience.

Dynamic algorithm for fitness function greatly improves the optimization efficiency of frequency selective surface for better design of radar.

Multiple objectives optimization of frequency selective surface (FSS) structures is challenging in electromagnetic wave filter design. For example, one of the sub-objectives, the sidelobe level (SLL), is critical to directional anti-interference, which is complicated and becomes the bottleneck for radar design. Here, we established a dynamic algorithm for fitness function to automatically adjust the weights of multiple objectives in the optimization process of FSS structures.

Highly Compressible Elastic Aerogel Spring-Based Piezoionic Self-Powering Pressure Sensor for Multifunctional Wearable Electronics.

To meet the rapid development of wearable flexible electronics, the multifunctional integrations into singe device are in extreme demand. In this paper, we developed novel self-powering multifunctional pressure sensors and supercapacitor-integrated device based on highly elastic silver nanowires@reduced graphene aerogel, being conductive to reduce integration difficulties and device size. Serving as an energy device, it behaves with a prominent specific capacitance of 146.

Simple-Structured OLEDs Incorporating Undoped Phosphorescent Emitters Within Non-Exciplex Forming Interfaces: Towards Ultraslow Efficiency Roll-Off and Low Driving Voltage for Indoor R/G/B Illumination.

To meet the requirement of indoor R/G/B monochrome illumination a simplified OLEDs structure and fabrication process must occur. Herein, a design philosophy of low efficiency roll-off and simple-structure OLEDs incorporating R/G/B phosphorescent ultrathin non-doped emissive layers (EMLs) within non-exciplex forming interfaces a luminescent system by a direct charge trapping mechanism has been reported, which uses bis(2-methyldibenzo[f,h]-quinoxaline)(acetylacetonate)iridium(III) (MDQ)Ir(acac), bis(3-phenylpyridin-e)iridium(III) (Ir(ppy)), and bis(3,5-difluoro-2 -(2-pyridyl)phenyl-(2-carboxypyridyl) iridiumII) (Firpic) as R/G/B luminescent dyes, respectively. Although the recombination zone is narrow in the designed OLEDs, the efficiency roll-off of the designed OLEDs are unexpectedly slow, due to stable charge trapping of the emitters and are refrained from concentration quenching in relatively low current density, but the luminance meets the requirement of indoor lighting.

The changing phenotypes and genotypes of invasive pneumococcal isolates from children in Shenzhen during 2013-2017.

Background: The phenotypes and genotypes of Streptococcus pneumoniae isolated from invasive pneumococcal diseases (IPDs) were changing all the time. To monitor these changes of phenotypes and genotypes of S. pneumoniae isolates from children, we examined antibiotic susceptibility, serotype distribution and sequence types (STs) of S.

Histological, hormonal and transcriptomic reveal the changes upon gibberellin-induced parthenocarpy in pear fruit.

Phytohormones play crucial roles in fruit set regulation and development. Here, gibberellins (GA), but not GA, induced pear parthenocarpy. To systematically investigate the changes upon GA induced pear parthenocarpy, dynamic changes in histology, hormone and transcript levels were observed and identified in unpollinated, pollinated and GA-treated ovaries.
