A Potent Antibacterial Peptide (P6) from the De Novo Transcriptome of the Microalga .

Marine microalgae are a rich source of natural products, and their amino acid-based antimicrobial agents are usually obtained by enzymatic hydrolysis, which is inefficient and limits the research on antimicrobial peptides (AMPs) from microalgae. In this study, is used as a model to predict antimicrobial peptides through high-throughput methods, and 471 putative peptides are identified based on the de novo transcriptome technique. Among them, three short peptides, P1, P6, and P7 were found to have antimicrobial activity against , , , and yeast , and they showed no hemolytic activity even at higher concentrations up to 10 mg/mL.

A weakly coordinating-intervention strategy for modulating Na solvation sheathes and constructing robust interphase in sodium-metal batteries.

Constructing powerful anode/cathode interphases by modulate ion solvation structure is the principle of electrolyte design. However, the methodological and theoretical design principles of electrolyte/solvation structure and their effect on electrochemical performance are still vague. Here, we propose a cationic weakly coordinating-intervention strategy for modulating the Na solvation sheathes and constructing robust anode/cathode interphases in sodium-metal batteries.

Unraveling the energy storage mechanism in graphene-based nonaqueous electrochemical capacitors by gap-enhanced Raman spectroscopy.

Graphene has been extensively utilized as an electrode material for nonaqueous electrochemical capacitors. However, a comprehensive understanding of the charging mechanism and ion arrangement at the graphene/electrolyte interface remain elusive. Herein, a gap-enhanced Raman spectroscopic strategy is designed to characterize the dynamic interfacial process of graphene with an adjustable number of layers, which is based on synergistic enhancement of localized surface plasmons from shell-isolated nanoparticles and a metal substrate.

Integration of molecular breeding and multi-resistance screening for developing a promising restorer line Guihui5501 with heavy grain, good grain quality, and endurance to biotic and abiotic stresses.

Rice, a critical staple on a global scale, faces escalating challenges in yield preservation due to the rising prevalence of abiotic and biotic stressors, exacerbated by frequent climatic fluctuations in recent years. Moreover, the scorching climate prevalent in the rice-growing regions of South China poses obstacles to the cultivation of good-quality, heavy-grain varieties. Addressing this dilemma requires the development of resilient varieties capable of withstanding multiple stress factors.

Modified Xiaoyao San reverses lipopolysaccharide-induced depression-like behavior through suppressing microglia M1 polarization via enhancing autophagy involved in PI3K/Akt/mTOR pathway in mice.

Ethnopharmacological Relevance: Modified Xiaoyao San (MXYS), a clinical empirical modified formula based on famous traditional Chinese herbal prescription Xiaoyao San, according to the "yu syndrome" theory of traditional Chinese medicine. MXYS has been shown to be an excellent effective therapy for depression patients in clinic, but the antidepressant mechanisms remain unclear.

Aim Of The Study: A growing body of evidence indicates the microglia autophagy and M1 polarized microglia (proinflammatory phenotype)-mediated neuroinflammation act critical roles in the pathogenesis of depression.

Functional OCT angiography reveals early retinal neurovascular dysfunction in diabetes with capillary resolution.

Altered retinal neurovascular coupling may contribute to the development and progression of diabetic retinopathy (DR) but remains highly challenging to measure due to limited resolution and field of view of the existing functional hyperemia imaging. Here, we present a novel modality of functional OCT angiography (fOCTA) that allows a 3D imaging of retinal functional hyperemia across the entire vascular tree with single-capillary resolution. In fOCTA, functional hyperemia was evoked by a flicker light stimulation, recorded by a synchronized time-lapse OCTA (i.

Study on the hepatotoxicity and potential mechanism of gefitinib based on CYP450 in mice and AML12 cells.

Objectives: Gefitinib is mainly used for the treatment of non-small-cell lung cancer. Hepatotoxicity is one of the main side effects of gefitinib, and seriously affects the treatment process of the disease. However, the hepatotoxicity mechanism of gefitinib remains unclear.

A Polysiloxane Delivery Vehicle of Cyclic -Halamine for Biocidal Coating of Cellulose in Supercritical CO.

Cyclic -halamines are highly antimicrobial, very stable, and not susceptible to bacterial resistance. A polysiloxane delivery vehicle was synthesized to deliver cyclic imide -halamine onto cellulose via a benign and universal procedure that does not require a harmful solvent or chemical bonding. In brief, Knoevenagel condensation between barbituric acid and 4-hydroxybenzaldehyde furnished 5-(4-hydroxybenzylidene)pyrimidine-2,4,6-trione, whose phenolic O-H was subsequently reacted with the Si-H of poly(methylhydrosiloxane) (PMHS) via silane alcoholysis.

Dynamic inverse SNR-decorrelation OCT angiography with GPU acceleration.

Dynamic OCT angiography (OCTA) is an attractive approach for monitoring stimulus-evoked hemodynamics; however, a 4D (3D space and time) dataset requires a long acquisition time and has a large data size, thereby posing a great challenge to data processing. This study proposed a GPU-based real-time data processing pipeline for dynamic inverse SNR-decorrelation OCTA (ID-OCTA), offering a measured line-process rate of 133 kHz for displaying OCT and OCTA cross-sections in real time. Real-time processing enabled automatic optimization of angiogram quality, which improved the vessel SNR, contrast-to-noise ratio, and connectivity by 14.

Effect of manual lymphatic drainage combined with vacuum sealing drainage on axillary web syndrome caused by breast cancer surgery.

The aim of the study was to explore the application value of manual lymphatic drainage combined with vacuum sealing drainage in axillary web syndrome (AWS) after breast cancer surgery. From 1 April 2020 to 1 June 2020, a total of 102 patients with AWS after axillary lymph node biopsy or axillary lymph node dissection in our hospital were included in this prospective study. According to the random number table method, all patients were divided into the study group (n = 51) and the control group (n = 51).
