Determination of Bioactive Components in Chrysanthemum Tea (Gongju) Using Hyperspectral Imaging Technique and Chemometrics.

The bioactive components of chrysanthemum tea are an essential indicator in evaluating its nutritive and commercial values. Combining hyperspectral imaging (HSI) with key wavelength selection and pattern recognition methods, this study developed a novel approach to estimating the content of bioactive components in chrysanthemums, including the total flavonoids (TFs) and chlorogenic acids (TCAs). To determine the informative wavelengths of hyperspectral images, we introduced a variable similarity regularization term into particle swarm optimization (denoted as VSPSO), which can focus on improving the combinatorial performance of key wavelengths and filtering out the features with higher collinearity simultaneously.

Crosslinking-Driven Chemical Homogeneity Enhances Performance of Pre-Seeded Perovskite Solar Cells.

Perovskite solar cells (PSCs) have achieved impressive efficiency, but their commercialization is limited by issues like chemical homogeneity within the perovskite films, leading to defects and phase segregation, which severely compromise the stability and performance of PSCs. This study presents a novel approach to overcoming these barriers by employing N,N-methylenebisacrylamide (MBA) as a multifunctional crosslinking agent within the perovskite structure. MBA enhances chemical uniformity both laterally and vertically, improves crystallinity, and boosts overall film stability by forming a robust crosslinked network that regulates nucleation and growth dynamics during the pre-seeding process.

Effects of Water and Nitrogen Regulation on Soil Environment and Crop Growth in a ||Alfalfa System.

The increasing scarcity of water and soil resources, combined with inefficient water and fertilizer management, poses significant challenges to agriculture in arid regions. This study aimed to determine an optimal water and nitrogen regulation model to alleviate water shortages and improve agricultural productivity and quality. In this study, a two-year experiment was conducted to investigate the effects of varying irrigation and nitrogen levels on the soil environment and crop growth in a ||alfalfa system (LB||AS).

Environmentally Stable Reversible Cavitand Molecular Switches Based on the Excimer of Perylene.

Environmentally stable novel flexible bisperylene resorcin[4]arene molecular switch cavitand B and the corresponding rigid cavitand A were synthesized and a single crystal was obtained. Spectroscopic analysis revealed the formation of an excimer of perylene within the cavitand. The presence of flexible chains in cavitand B confers a high degree of environmental stability, rendering its fluorescence unaffected by external factors such as pH and temperature variations.

The structural discrepancy between the ability of fructan and arabinogalactan to cure acute pharyngitis in Hosta plantaginea (Lam.) Aschers flowers.

The flowers of Hosta plantaginea (Lam.), a traditional Chinese medicine, is utilized for the treatment of sore throat, aphonia, and cough alleviation. The polysaccharides HPFP-1 and HPFP-2 were separated from these plants through water-soluble alcohol precipitation and column chromatography.

Peroxynitrite activatable NIR-II probe for tumor diagnosis and photothermal therapy in vivo.

Peroxynitrite (ONOO) is a bioactive molecule involved in various biochemical processes, and the abnormal concentration fluctuations of ONOO in living systems are closely associated with various diseases, including cancer. An important characteristic of the tumor microenvironment is the overexpression of ONOO, highlighting the significance of specific detection of ONOO in distinguishing between tumor tissue and normal tissue. A single near-infrared second window (NIR-II) molecular probe integrated fluorescence imaging and photothermal therapy can achieve precise localization and effective ablation of deep-seated tumor tissue.

Rapid identification of moxa wool storage period based on hyperspectral imaging technology and machine learning.

Moxa wool (MW), derived from the dried leaves of , plays a significant role in traditional Chinese medicine. However, the quality of MW varies with its storage period, impacting its therapeutic efficacy. Traditional methods for quality detection are limited and destructive.

Development of a Robust Strain for Efficient Co-Fermentation of Mixed Sugars and Enhanced Inhibitor Tolerance through Protoplast Fusion.

The economical and efficient commercial production of second-generation bioethanol requires fermentation microorganisms capable of entirely and rapidly utilizing all sugars in lignocellulosic hydrolysates. In this study, we developed a recombinant strain, BLH510, through protoplast fusion and metabolic engineering to enhance its ability to co-ferment glucose, xylose, cellobiose, and xylooligosaccharides while tolerating various inhibitors commonly found in lignocellulosic hydrolysates. The parental strains, LF1 and BLN26, were selected for their superior glucose/xylose co-fermentation capabilities and inhibitor tolerance, respectively.

Optimal therapeutic strategies for hepatic metachronous oligometastatic nasopharyngeal carcinoma: Insights from a retrospective study.

Hepatic metachronous oligometastatic nasopharyngeal carcinoma (hmoNPC) exhibits distinct clinical characteristics compared to other types of metastatic NPC. We investigated the optimal therapy for hmoNPC. 160 patients with hmoNPC treated in Sun Yat-sen University Cancer Center between 2010 and 2021 were retrospectively recruited.

Anxiety and depression in nasopharyngeal carcinoma patients and network analysis to identify central symptoms: A cross-sectional study from a high-incidence area.

Purpose: To determine the prevalence of anxiety and depression in patients with nasopharyngeal carcinoma (NPC) and to identify central symptoms and bridge symptoms among psychiatric disorders.

Methods: This cross-sectional study recruited patients with NPC in Guangzhou, China from May 2022, to October 2022. The General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used for screening anxiety and depression, respectively.

Relationships among anxiety, depression, and health-related quality of life in adult epilepsy: A network analysis.

Objective: Comorbid depression and anxiety in patients with epilepsy (PWE) are common and frequently under-treated, thus, causing poor health-related quality of life (HRQoL). However, little is known regarding the interconnections between anxious/depressive symptoms and the dimensions of HRQoL. Therefore, we conducted a network analysis to explore these relationships in detail among Chinese adult PWE.

Slow-digestive yeast protein concentrate: An investigation of its in vitro digestibility and digestion behavior.

Yeast protein concentrate, a by-product of the fermentation industry waste, is a potential alternative protein source with high nutritional quality, environmental sustainability, and functional properties. However, its digestibility and digestion behavior are poorly understood. In this study, we compared the in vitro digestion behavior of yeast protein concentrate and whey protein concentrate using simulated gastrointestinal conditions.

Synthesis of Imidazole-Based Deep Eutectic Solvents as Solid Lubricants: Lubricated State Transition.

The controllable character of the melting point of deep eutectic solvents (DESs) makes it easy to realize lubricated state transitions and produce excellent lubricating properties during friction. In this work, a series of novel imidazole-based DESs were synthesized to present a room-temperature solid state by shifting its eutectic point. Tribological test results show that the wear volume of these DESs decreases as the alkyl chains of the hydrogen bond donors increase.

A nomogram model for predicting lower extremity deep vein thrombosis after gynecologic laparoscopic surgery: a retrospective cohort study.

Objective: To investigate the risk factors associated with lower extremity deep vein thrombosis (LEDVT) and to establish a predictive model for patients who undergo gynecologic laparoscopic surgery.

Methods: A review of clinical data was conducted on patients who underwent gynecologic laparoscopic surgery between November 1, 2020, and January 31, 2022. Patients who developed LEDVT after surgery were included as the observation group, while the control group comprised patients who did not experience complications.
