A biguanide chitosan-based hydrogel adhesive accelerates the healing of bacterial-infected wounds.

The development of tissue adhesives with good biocompatibility and potent antimicrobial properties is crucial for addressing the high incidence of surgical site infections in emergency and clinical settings. Herein, an injectable hydrogel adhesive composed of chitosan biguanidine (CSG), oxidized dextran (ODex) and tannin (TA) was synthesized primarily through Schiff-base reactions, hydrogen bonding, and electrostatic interactions. TA was introduced into the CSG/ODex hydrogel to prepare a physicochemically double cross-linked hydrogel.

Polyvinyl Butyral Loading with Combined Repellents Showed Effective Protection Against Leech Bites in Diverse Situations.

Leech bites have long been a persistent problem for individuals engaged in outdoor activities, particularly in environments such as moors, jungles, and grasslands. Methods to prevent leech bites are anecdotal and individual, highlighting the need for the development of universal and effective repellent formulations. This study developed a novel approach for repelling leeches using combined repellent agents and a film-forming material (polyvinyl butyral), to enhance efficiency in multi-scenario applications.

Spectrum-Effect Relationship between HPLC Fingerprint and Anti-Inflammatory and Analgesic Activities of (A. Gray) Solms-Laub.

The predominant objective of the research is to establish the anti-inflammatory and analgesic spectrum-effect relationship of (A. Gray) Solms-Laub (CF), to reveal the pharmacodynamic basis of the anti-inflammatory and analgesic effects of CF. The fingerprints of ten batches of CF from various origins were established by high-performance liquid chromatography (HPLC) and evaluated for similarity, hierarchical cluster analysis (HCA), and principal component analysis (PCA).

Study on the Fingerprint Spectrum and the Spectrum-Effect Relationship of Analgesic and Anti-Inflammatory Effects of the Aqueous Extract from Benth.

Benth. () is one of the most frequently utilized traditional Chinese medicine in Zhuang medicine. Simultaneously, it has been included in the "Quality Standard of Zhuang medicine in Guangxi Zhuang Autonomous Region (Vol.

A Monte Carlo algorithm to improve the measurement efficiency of low-field nuclear magnetic resonance.

Nuclear magnetic resonance (NMR) has shown good applications in engineering fields such as well logging and rubber material ageing assessment. However, due to the low magnetic field strength of NMR sensors and the complex working conditions of engineering sites, the signal-to-noise ratio (SNR) of NMR signals is low, and it is usually necessary to increase the number of repeated measurements to improve the SNR, which means a longer measurement time. Therefore, it is especially important to set the measurement parameters appropriately for onsite NMR.

Spectrum-effect relationship between hplc fingerprint and anti-inflammatory activity of n-butanol parts of Tetrastigma planicaule (Hook) Gagnep.

The present study aimed to evaluate the spectrum-effect relationships between high-performance liquid chromatography fingerprints and anti-inflammatory effects of Tetrastigma planicaule(Hook.)Gagnep. Chemical fingerprints of ten batches of Tetrastigma planicaule from various sources were obtained by HPLC.

Study on the Spectrum-Effect Correlation of Anti-Inflammatory Active Extract of Beille.

Beille () is a commonly used medicine of the Bourau and Yao nationalities. However, the composition of is complex, and simple chemical fingerprints cannot accurately evaluate the relationship between its composition and efficacy. In this study, high-performance liquid chromatography (HPLC) method was used to establish the fingerprint of the ethyl acetate extract of .

Transition Activity Recognition System based on Standard Deviation Trend Analysis.

With the development and popularity of micro-electromechanical systems (MEMS) and smartphones, sensor-based human activity recognition (HAR) has been widely applied. Although various kinds of HAR systems have achieved outstanding results, there are still issues to be solved in this field, such as transition activities, which means the transitional process between two different basic activities, discussed in this paper. In this paper, we design an algorithm based on standard deviation trend analysis (STD-TA) for recognizing transition activity.

Polysaccharides from via Ultrasound-Assisted Enzymatic Extraction Using Response Surface Methodology.

An efficient procedure for ultrasound-assisted enzymatic extraction of crude polysaccharides from (crude TFP) using response surface methodology (RSM) was developed. The Box-Behnken design was applied to optimize the effects of pH (), enzyme amount (), extraction temperature (), and liquid-to-solid ratio () on the extraction. The statistical analysis indicated that the independent variables (, , and ), the quadratic coefficients (, , , and ), and the interaction coefficient () had significant impact on the yield of crude TFP.
