The antibiofilm effect and mechanism of silver nanowire-modified glass ionomer cement against multi-species oral biofilm.
BMC Oral Health
January 2025
Department of Stomatology, School of Medicine, Xiamen University, Xiamen, China.
Background: To investigate the antibiofilm effect and mechanism of the silver nanowire (AgNW)-modified glass ionomer cement (GIC) against multi-species oral biofilm, and to examine the mechanical and biochemical properties of this novel GIC material.
Methods: Conventional GIC was incorporated with different concentrations of AgNW and silver nanoparticles (AgNP). Multi-species biofilms of Streptococcus mutans, Streptococcus sobrinus, Lactobacillus fermentum, and Lactobacillus rhamnosus were cultured for 72 h on GIC specimens.
A randomized double-blind clinical trial investigating the effects of ellagic acid on glycemic status, liver enzymes, and oxidative stress in patients with non-alcoholic fatty liver disease.
BMC Complement Med Ther
January 2025
Department of Nutrition, Qazvin University of Medical Sciences, Qazvin, Iran.
Background: It seems that oxidative stress is involved in the occurrence and progression of non-alcoholic fatty liver disease (NAFLD). Considering the antioxidant features of Ellagic acid (EA), this study was designed to assess the effect of EA on some biochemical factors in patients with NAFLD.
Methods: In this clinical trial, 44 patients were selected based on including criteria and randomly received 180 mg of EA per day (n = 22) or placebo (n = 22) for 8 weeks.
Differences and driving factors of leaf functional traits between old tree and mature tree of Pinus tabulaeformis in the Loess Plateau.
BMC Plant Biol
January 2025
Key Comprehensive Laboratory of Forestry, Northwest A&F University, Yangling, Shaanxi Province, 712100, P. R. China.
Background: Study the leaf functional traits is highly important for understanding the survival strategies and climate adaptability of old trees. In this study, the old (over 100 years old) and mature trees (about 50 years old) of Pinus tabulaeformis in the Loess Plateau were studied, and the variation of 18 leaf functional traits (6 economic, 4 anatomical, 2 photosynthetic and 6 physiological traits) was analyzed to understand the differences of survival strategies between old and mature trees. Combined with transcriptome and simple sequence repeats (SSR) techniques, the effects of soil property factors and genetic factors on leaf functional traits and the potential molecular mechanisms of traits differences were studied.

Sci Rep
January 2025
Mechanical and Industrial Engineering Department, Universitas Gadjah Mada, Yogyakarta, Indonesia.
Research on flexible strain sensors has grown rapidly and is widely applied in the fields of soft robotics, body motion detection, wearable sensors, health monitoring, and sports. In this study, MXene was successfully synthesized in powder form and combined with multi-walled carbon nanotube (MWCNT) to develop MWCNT@MXene conductive network-based flexible strain sensors with silicone rubber (SR) substrate. Combining MWCNTs with MXene as a conductive material has been shown to significantly improve the sensor performance, due to MXene's high conductivity properties that strengthen the MWCNT conductive pathway, increase sensitivity, and improve sensor stability.

Department of Botany, University of Wrocław, Kanonia 6/8, 50-328, Wrocław, Poland.
Field margins have considerable ecological significance in farming landscapes, but are subject to constant changes resulting from natural processes and anthropogenic pressures. Understanding the balance of these processes is important from an ecological and conservation perspective. We measured 20 variables related to margin composition, woody vegetation and adjacent cropland fragmentation in 70 field margins in SW Poland in 2004 and 2006 (Poland's accession to the EU), and then resurveyed in 2021 by using the same protocol.
