A Study on the Extraction, Fermentation Condition Optimization, and Antioxidant Activity Assessment of Polysaccharides Derived from .

exhibits advantages such as strong thermotolerance, rapid growth rate, and high safety, making it an excellent host cell for the production of bio-based products. In this study, two exopolysaccharides, KE1 and KE2, were isolated from the fermentation broth of the strain KM-502, and their hydroxyl radical scavenging, DPPH scavenging, and Fe-reducing activities were evaluated. In vitro antioxidant assays demonstrated that exopolysaccharide KE2 exhibited superior antioxidant activity compared to KE1.

Orthopedic Implant Infection Management: Prevention, Barrier Breakthrough, and Immunomodulation.

The widespread use of biomedical implants has led to a surge in implant-associated infections, particularly in orthopedic applications, where biofilm formation, antibiotic resistance, and immune dysregulation synergistically exacerbate therapeutic challenges, increasing patient morbidity and healthcare burdens. This review delineates the pathogenic mechanisms, especially for , underpinning microbial persistence in orthopedic implant infections. Key mechanisms include biofilm-mediated physical barrier formation, abscesses, invasion of the osteocyte lacuno-canalicular network, and immune evasion that shield pathogens from antimicrobial agents and host defenses.

A Rho-Type GTPase Protein Pocdc42 Regulates the Development and Cellulase Expression of Penicillium oxalicum.

Penicillium oxalicum is a filamentous fungus widely recognized for its robust production of cellulases. It features complex pathways that govern the triggered expression of these enzymes. Signal transduction serves a critical function in the effective management of cellulase induction and expression.

The Impact of Robot-Assisted Digital Education on Prenatal Women's Health Literacy: A Randomized Controlled Trial.

This study aimed to evaluate the effectiveness of a robot-assisted digital education method in reducing anxiety and promoting healthy behaviors among pregnant women with gestational diabetes mellitus (GDM). A randomized controlled trial was conducted to compare the impact of robot-assisted health education with conventional video-based education. A total of 66 pregnant women from a single hospital were randomly assigned to either the experimental group ( = 32) or the control group ( = 34).

Effects of robot-assisted digital storytelling on hospitalized children's communication during the COVID-19 pandemic.

This study proposed a robot-assisted digital storytelling approach to reduce hospitalized children's anxiety about intravenous injections and to improve their therapeutic communication and therapeutic engagement. In order to verify the effectiveness of the robot-assisted digital storytelling approach, a randomized controlled study was implemented. A total of 47 children from a regional hospital were randomly assigned to an experimental group ( = 21) and a control group ( = 26).

An Advanced Chicken Face Detection Network Based on GAN and MAE.

Achieving high-accuracy chicken face detection is a significant breakthrough for smart poultry agriculture in large-scale farming and precision management. However, the current dataset of chicken faces based on accurate data is scarce, detection models possess low accuracy and slow speed, and the related detection algorithm is ineffective for small object detection. To tackle these problems, an object detection network based on GAN-MAE (generative adversarial network-masked autoencoders) data augmentation is proposed in this paper for detecting chickens of different ages.

CC-type glutaredoxin, MeGRXC3, associates with catalases and negatively regulates drought tolerance in cassava (Manihot esculenta Crantz).

Glutaredoxins (GRXs) are essential for reactive oxygen species (ROS) homeostasis in responses of plants to environment changes. We previously identified several drought-responsive CC-type GRXs in cassava, an important tropical crop. However, how CC-type GRX regulates ROS homeostasis of cassava under drought stress remained largely unknown.

Electronic healthcare records and external outcome data for hospitalized patients with heart failure.

Heart failure is one of the most important reasons for hospitalization among elderly individuals and is associated with significant mortality and morbidity. Epidemiological studies require the establishment of high-quality databases. Several datasets that primarily involve heart failure populations have been established in Western countries and have generated many high-quality studies.
