Specific hydroxylation and glucuronidation of 2'-hydroxyflavanone by Streptomyces coeruleorubidus NRRL B-2569.

Flavonoids constitute a class of natural compounds with varied bioactivities. Nevertheless, the potential health benefits of flavonoids for humans are often compromised by their low water solubility and limited bioavailability. In this study, four derivatives, namely 2',5'-dihydroxyflavanone (2), 5'-dihydroxyflavone-2'-O-β-d-glucuronide (3), and two isomers of hydroxyflavanone-2'-O-β-d-glucuronide (4 and 5), were biosynthesized from substrate 2'-hydroxyflavanone (1) through the specific hydroxylation and glucuronidation using Streptomyces coeruleorubidus NRRL B-2569.

Non-contrast MRI based machine learning and radiomics signature can predict the severity of primary lower limb lymphedema.

Purpose: According to International Lymphology Society guidelines, the severity of lymphedema is determined by the difference in volume between the affected limb and the healthy side divided by the volume of the healthy side. However, this method of measuring volume is time-consuming, laborious, and has certain errors in clinical applications.Therefore, this study aims to explore whether machine learning radiomics features based on non-contrast magnetic resonance imaging (NCMRI) can predict the severity of primary lower limb lymphedema.

CsCPC, an R3-MYB transcription factor, acts as a negative regulator of citric acid accumulation in Citrus.

The citric acid accumulation during fruit ripening determines the quality of fleshy fruits. However, the molecular mechanism underlying citric acid accumulation is not clearly understood yet in citrus due to the scarcity of paired germplasm that exhibits significant difference in organic acid accumulation. Two citrus triploid hybrids with distinct citric acid content in their mature fruits were herein identified from a previously conducted interploidy cross in our group, providing an ideal paired material for studying acid accumulation in citrus.

Perspectives on biomarkers of reproductive aging for fertility and beyond.

Reproductive aging, spanning an age-related functional decline in the female and male reproductive systems, compromises fertility and leads to a range of health complications. In this Perspective, we first introduce a comprehensive framework for biomarkers applicable in clinical settings and discuss the existing repertoire of biomarkers used in practice. These encompass functional, imaging-based and biofluid-based biomarkers, all of which reflect the physiological characteristics of reproductive aging and help to determine the reproductive biological age.

Microglia stimulation produces antidepressant-like effects in a mouse depression model induced by adolescent chronic unpredictable stress.

Depression triggered by harmful stress in adolescents is a common phenomenon that can lead to serious social problems. Its treatment is still frustrating in the clinic. We reported the phenomenon that a 12-day chronic unpredictable stress (CUS), starting on postnatal day 28, led to a significant decrease in the number of microglia in the dentate gyrus of the hippocampus in adult mice.

Distribution and controlling factors of dissolved inorganic carbon in urban rivers of a North China megacity: Insights from δC.

Transportation and transformation of the dissolved inorganic carbon (DIC) play a critical role in the regional carbon cycle. To clarify the natural and anthropogenic impacts on DIC, the concentration and isotopic composition of DIC (δC) in two typical urban rivers in northern China (Yongding River, YDR, and Chaobai River, CBR) were measured. Mass-balanced calculations were employed to quantify the impacts of different weathering processes.

Exploring the diversity of anti-defense systems across prokaryotes, phages and mobile genetic elements.

The co-evolution of prokaryotes, phages and mobile genetic elements (MGEs) has driven the diversification of defense and anti-defense systems alike. Anti-defense proteins have diverse functional domains, sequences and are typically small, creating a challenge to detect anti-defense homologs across prokaryotic and phage genomes. To date, no tools comprehensively annotate anti-defense proteins within a desired sequence.

Engineered bacteria that self-assemble bioglass polysilicate coatings display enhanced light focusing.

Cutting-edge photonic devices frequently rely on microparticle components to focus and manipulate light. Conventional methods used to produce these microparticle components frequently offer limited control of their structural properties or require low-throughput nanofabrication of more complex structures. Here, we employ a synthetic biology approach to produce environmentally friendly, living microlenses with tunable structural properties.

Ultrastretchable and highly sensitive ionic conductive hydrogel for environmentally resistant all-in-one human-motion sensors.

Conductive hydrogels have been considered ideal candidate materials for fabricating human-motion sensors due to their combination properties of electronic and tissue-like soft nature and the similar functions of human skin with mechanical and sensory properties. However, the perfect integration of multiple functionalities such as environmentally tolerant, stretchable, self-adhesive, self-healing, transparent, high sensitivity, and rapid response in one system (all-in-one) is still a significant challenge. Herein, a novel ionic conductive hydrogel platform with excellent comprehensive performance through multiple dynamic interactions was prepared by employing [BMIm]BF/glycerol/water ternary solvent system.

ArMYB89 and ArCOP1 interaction modulates anthocyanin biosynthesis in Acer rubrum leaves under low-temperature conditions.

Cadmium distribution and availability in different particle-size aggregates of post-harvest paddy soil amended with bio-based materials.

Research on the use of organic materials as soil amendments for the remediation of Cd-contaminated agricultural land exists. However, the mechanisms based on which organic materials affect the distribution and availability of Cd in soil aggregates remain unclear. Here, Cd-contaminated paddy soil and different bio-based materials were used for rice pot experiments.

Research on intervention strategies for fire rescue personnel's competency frustration: EEG experimental validation.

In order to accurately measure the level of competency frustration and what measures to take to alleviate the negative effects of competency frustration, 35 graduate students were selected to verify the effect of the frontal lobe asymmetry (FAA) as a judgement of the competence frustration level using EEG experimental method. On this basis, through two stopwatch stopping experiments, 108 fire rescue personnel were selected to conduct the experiments to investigate the intervention effects of developmental feedback and compassion-focused therapy in turn. The results showed that frontal asymmetry could be used as an EEG indicator for judging competency frustration, and the intervention method of compassion-focused therapy reduced the level of competency frustration of the subjects, while developmental feedback interventions did the opposite.

Matrix vesicles from osteoblasts promote atherosclerotic calcification.

Atherosclerotic calcification often coincides with osteoporosis, suggesting a potential interplay between bone and vascular mineralization. Osteoblast-derived matrix vesicles (Ost-MVs), pivotal in bone mineralization, have emerged as potential contributors to ectopic vascular calcification. However, the precise role of Ost-MVs in vascular calcification and the underlying mechanisms remain elusive.

A Scenario for a Carbon-Neutral Ammonia-Fueled Engine Mediated by Catalytic NH Cracking and CO Hydrogenation.

Utilizing near zero-carbon NH as fuel in engines is promising for carbon-neutrality. However, the application of NH into the engine suffers from the intrinsic poor combustion characteristics of NH and the emission of harmful NO exhausts. Herein, we proposed and successfully confirmed a novel scenario for converting a conventional "CH-fueled" engine to "NH-fueled" engine.
