New Insight into the Related Candidate Genes and Molecular Regulatory Mechanisms of Waterlogging Tolerance in Tree Peony .

Research on the waterlogging tolerance mechanisms of helps us to further understand these mechanisms in the root system and enhance its root bark and oil yields in southern China. In this study, root morphological identification, the statistics of nine physiological and biochemical indicators, and a comparative transcriptome analysis were used to investigate the waterlogging tolerance mechanism in this plant. As flooding continued, the roots' vigor dramatically declined from 6 to 168 h of waterlogging, the root number was extremely reduced by up to 95%, and the number of roots was not restored after 96 h of recovery.

An Efficient In Vitro Regeneration Protocol and the Feature of Root Induction with Phloroglucinol in .

, a plant of substantial economic significance, continues to face constraints in achieving large-scale propagation. In vitro propagation offers a promising avenue for the production of disease-free plants and the genetic transformation of peonies to instill novel traits. However, significant challenges persist in tissue culture, particularly with regards to the reproduction coefficient of shoots and the rooting process.

Polycaprolactone/polylactic acid nanofibers incorporated with butyl hydroxyanisole /HP-β-CD assemblies for improving fruit storage quality.

In this study, the inclusion complex was prepared with butyl hydroxyanisole (BHA) as the functional substance and 2-hydroxypropyl beta-cyclodextrin (HP-β-CD) as the main molecule by ultrasound mediation. The inclusion complex was mixed with polycaprolactone (PCL)/polylactic acid (PLA), and nanofiber films loaded with different concentrations of BHA/HP-β-CD inclusion complex were prepared by electrospinning for fruit preservation. The scanning electron microscopy and infrared spectroscopy characterization results showed that HP-β-CD successfully embedded BHA in the cavity.

Ultrasound effect on flavor profile of beef jerky produced with partial potassium salt substitute based on GC-IMS technology.

Traditional beef jerky contains a high content of sodium salt while the reduction of sodium usage impairs the flavor of final product. Regarding above issues, this research innovatively applied ultrasound-assisted salts (NaCl and KCl) recombination in the pickling stage of low-sodium beef jerky, and further compared the flavor differences caused by ultrasound by sensory evaluation, E-nose and GC-IMS. Besides, the changes of physicochemical qualities were explored including salts content, color and shear force.

Meta-analysis of the effects of probiotics on hyperlipidemia.

Background: The potential role of probiotics in mitigating hyperlipidemia has garnered increasing evidence, yet the specific mechanisms warrant further investigation.

Objective: This study aimed to examine the alterations in short-chain fatty acids (SCFAs), a hypothesized lipid-lowering mechanism of probiotics, in animal models and to evaluate the lipid-lowering effects of probiotics on hyperlipidemic animal models through a meta-analysis of preclinical experiments. Methods: A comprehensive search of PubMed, Web of Science, EMBASE, Cochrane Library and Google Scholar up to June 2024 yielded nine studies that met the inclusion criteria (INPLASY registration number: No.

PCL/soy peptide nanofibers incorporated with riboflavin/HP-β-CD assemblies for improving fruit storage quality.

In this study, we first successfully developed functionalized electrospun nanofibers (PCL/SP/ICs) loaded with Riboflavin (RF) for fruit preservation with inclusion complexes (RF/HP-β-CD, IC) formed by encapsulating RF with hydroxypropyl-β-cyclodextrin (HP-β-CD) as a core material and soy peptide-assisted polycaprolactones (PCL/SP) as an overwrap material. Compared to 1 wt% and 5 wt% IC, nanofibers implanted with 3 wt% IC had an acceptable water contact angle (87.40°), good thermal stability, and superior mechanical properties.

Extraction and Synthesis of Typical Carotenoids: Lycopene, β-Carotene, and Astaxanthin.

Carotenoids are tetraterpene compounds acting as precursors to vitamin A, with functions that include protecting eyesight, enhancing immunity, promoting cell growth and differentiation, and providing antioxidative benefits. Lycopene, β-carotene, and astaxanthin are particularly critical for health and have diverse applications in food, health products, and medicine. However, natural carotenoids are encased within cell structures, necessitating mechanical methods to disrupt the cell wall for their extraction and purification-a process often influenced by environmental conditions.

Adaptive strategies in architecture and allocation for the asymmetric growth of camphor tree (Cinnamomum camphora L.).

The stability-related asymmetry in roots, trunk, and crown is always found as a typical effect of biomechanical design under heterogeneous stimulus environment. However, it appears to be a conflict between the biomechanical principle and the source-sink distance of nutrient allocation strategies when the orientational asymmetry occurs. Adaptive growth strategies associated with biomass and nutrient allocation remain to be explored.

PCL/Locust bean gum nanofibers loaded with HP-β-CD/Epicatechin clathrate compounds for fruit packaging.

In this work, the hydroxypropyl-β-cyclodextrin (HP-β-CD)/Epicatechin (EC) clathrate compounds were rapidly prepared based on an ultrasound-mediated method, and Polycaprolactone (PCL)/Locust bean gum (LBG) nanofibers loaded clathrate compounds were fabricated by electrostatic spinning (ELS) for fruit packaging. The results of infrared spectrum and crystal type analysis proved that clathrate compounds were successfully prepared. With the addition of clathrate compounds, the diameter of fibers increased from 553.

Dual-signal ratiometric electrochemiluminescence biosensor based on Au NPs-induced low-potential emission of PFO Pdots and LSPR-ECL mechanism for ultra-sensitive detection of microRNA-141.

In this study, we have for the first time constructed a ratiometric ECL biosensor for the ultrasensitive detection of microRNAs (miRNAs) using gold nanoparticles (Au NPs) to trigger both the low-potential emission from conjugated polymer poly(9,9-dioctylfluorene-2,7-diyl) dots (PFO Pdots) and the LSPR-ECL effect with sulfur-doped boron nitride quantum dots (S-BN QDs). PFO Pdots were first applied to the Au NPs-modified electrode, followed by covalent binding to capture the hairpin H1. Immediately thereafter, a small amount of miRNA-141 was able to generate a large amount of output DNA (OP) by traversing the target cycle.

Development of a ratiometric fluorescent probe for the detection of peroxynitrite.

Peroxynitrite is one of the important reactive oxygen species in the human body and is closely related to the physiological and pathological processes of many diseases. Therefore, the development of probes to detect peroxynitrite is important for diagnostic and pathologic studies of many diseases. In this work, a ratiometric probe was designed using benzopyran as the recognition site, and the sensitivity and selectivity of the probe were tuned by modification of substituents on benzopyran.

Boosting one-step degradation of shrimp shell waste to produce chitin oligosaccharides at smart nanoscale enzyme reactor with liquid-solid system.

Chitin oligosaccharides (CTOS) possess potential applications in food, medicine, and agriculture. However, lower mass transfer and catalytic efficiency are the main kinetic limitations for the production of CTOS from shrimp shell waste (SSW) and crystalline chitin. Chemical or physical methods are usually used for pretreatment to improve chitinase hydrolysis efficiency, but this is not eco-friendly and cost-effective.

Tripedal DNA Walker as a Signal Amplifier Combined with a Potential-Resolved Multicolor Electrochemiluminescence Strategy for Ultrasensitive Detection of Prostate Cancer Staging Indicators.

A multicolor electrochemiluminescence (ECL) biosensor based on a closed bipolar electrode (BPE) array was proposed for the rapid and intuitive analysis of three prostate cancer staging indicators. First, [Irpic-OMe], [Ir(ppy)(acac)], and [Ru(bpy)] were applied as blue, green, and red ECL emitters, respectively, whose mixed ECL emission colors covered the whole visible region by varying the applied voltages. Afterward, we designed a simple Mg-dependent DNAzyme (MNAzyme)-driven tripedal DNA walker (TD walker) to release three output DNAs.
