The results of long-term author's studies of the optical and complex-forming properties of more than 30 synthetic low-molecular-weight fluorophores specific for DNA are described. These studies made it possible to significantly expand the already existing database of properties of such compounds, clarify the ideas about the patterns linking the mentioned properties of fluorophores with their structure, and formulate recommendations on designing new effective DNA-specific fluorophores. The results of these studies can be used, in particular, in the development of new rapid methods for diagnosing various diseases, biotesting of probiotic and antibiotic properties of various products and wastes, etc.

Idesia polycarpa Maxim (IPM) cake meal, a major by-product of oil extraction, is often discarded in large quantities, resulting in considerable waste. This study explored the extraction of IPM polysaccharides (IPMPs) from cake meal using the innovative ultrasonic-assisted three-phase partitioning (UTPP) method, in comparison with conventional techniques, including acid, medium-temperature alkali, chelating agent, and enzyme extraction methods. The IPMP-UT prepared via UTPP method achieved superior extraction efficiency (10.

Significant changes in a system's dynamics can be understood through modifications in the topological structure of its flow in phase space. In the Earth's climate system, such changes are often referred to as tipping points. One of the large-scale components that may pass a tipping point is the Atlantic Meridional Overturning Circulation.

Purpose: The caregiver burden of individuals with dysphagia is a major concern. Currently, assessment tools specifically designed for this population are lacking. The present study aimed to translate the Caregiver Analysis of Reported Experiences with Swallowing Disorders (CARES) Questionnaire into Mandarin Chinese and evaluate its psychometric properties.

Purpose: To develop and assess the psychometric properties of a quality of life (QoL) assessment tool for Chinese patients treated with intravitreal injection (IVI) of anti-vascular endothelial growth factor (anti-VEGF).
Methods: We developed a 31-item IVI-QoL questionnaire using semi- structured patient interviews and expert panel consultation, drawing on a study of the literature. After pretesting on a subset of patients undergoing IVI, the questionnaire was pared down to 23 items.
