Mannitol: A novel chemical marker in stingless bee honey.

Stingless bee honey (SBH) has garnered attention as a natural sweetener and functional food, recognized for its exceptional biological activity and distinctive flavour. Compared to honey bee honey, SBH has lower annual production but commands a higher market value, making it more susceptible to adulteration. During an analysis of trehalulose in SBH, we unexpectedly identified the naturally occurring sugar alcohol, mannitol.

Development of morphology-dependent nanoselenium carriers for enhancing biological activity and reducing plant stress.

Owing to their small size, morphology and release modification properties, nanopesticides are considered promising alternative strategies for enhancing biological activity and minimizing pesticide losses. In this study, we used a colloidal self-assembly method to develop a morphology-stable, regularly rod-shaped nanoselenium pesticide carrier (NSer), which was further modified with chitosan. After loading penthiopyrad (PEN), the biological activity of NSer@PEN and its impact on the physiological and biochemical processes of plants were further compared with those of spherical nanoselenium pesticides (NSes@PEN) and commercial materials (20 % PEN SC).

Functional analysis of the PcCDPK5 gene in response to allelopathic substances on p-hydroxybenzoic acid (p-HBA) stress in patchouli.

Calcium-dependent protein kinase (CDPK) is an important mediator for Ca signal recognition and transduction, playing a crucial role in plant stress response. Previous studies have shown that PcCDPK5 may be involved in the response of patchouli to p-hydroxybenzoic acid (p-HBA) stress. In this study, we further found that the subcellular localization of PcCDPK5 protein is in the cytoplasm, and its gene expression is closely related to continuous cropping (CC) and p-HBA stress.

Enzymes offer a promising avenue for enhancing the competitiveness of biodegradable plastics in environmental restoration and the circular economy.

As a promising alternative to traditional plastics, the widespread application of biodegradable plastic (BP) will help solve worsening environmental problems. Enzymes such as cutinase, lipase, protease and esterase produced by bacteria and fungi in the environment play a crucial role in the degradation, recycling and valorization of BP by degrading them into low-molecular-weight oligomers or small monomers. These enzymes offering advantages such as high efficiency, cleanliness, safety and environmental friendliness, making them more competitive in environmental restoration and circular economy.

Revealing structure-performance relationship of biomimetic cyclodextrin metal-organic framework composite electrolytes for dendrite-free lithium metal batteries.

Cyclodextrin metal-organic frameworks (CD-MOFs) with infinitely extensible network structures show potential applications in lithium metal batteries. However, the disordered accumulation of CD-MOF particles leads to slow interparticle diffusion of ions, so the CD-MOF composite electrolytes are needed to be developed. In addition, the influences of CD-MOFs structure on the electrochemical performance of the composite electrolytes remains unclear.

Perturbative Framework for Engineering Arbitrary Floquet Hamiltonian.

We develop a systematic perturbative framework to engineer an arbitrary target Hamiltonian in the Floquet phase space of a periodically driven oscillator based on Floquet-Magnus expansion. The high-order errors in the engineered Floquet Hamiltonian are mitigated by adding high-order driving potentials perturbatively. We introduce a transformation method that allows us to obtain an analytical expression of the leading-order correction drive for engineering a target Hamiltonian with discrete rotational and chiral symmetries in phase space.

A π-Extended AIE Platform for Pattern Recognition of Glycosaminoglycans.

Accurate discrimination of complicated glycosaminoglycans is a challenging but meaningful task for ensuring their safe use in clinics. With the purpose of reducing the production cost of sensor arrays for glycosaminoglycans, three fluorescence turn-on sensors named , , and were readily synthesized by simple alkylation of the pyridyl units of the π-extended AIEgen, namely, tetra-(4-pyridylphenyl) ethylene. The designed sensors are cross-reactive toward tested glycosaminoglycans including heparin, chondroitin sulfate, hyaluronic acid, and dextran sulfate, whose mechanism could be ascribed to the multivalent electrostatic, CH···π, and hydrophobic interactions between the sensors and different glycosaminoglycans to form corresponding fluorescent aggregates.

Identification of Intracranial Germ Cell Tumors Based on Facial Photos: Exploratory Study on the Use of Deep Learning for Software Development.

Background: Primary intracranial germ cell tumors (iGCTs) are highly malignant brain tumors that predominantly occur in children and adolescents, with an incidence rate ranking third among primary brain tumors in East Asia (8%-15%). Due to their insidious onset and impact on critical functional areas of the brain, these tumors often result in irreversible abnormalities in growth and development, as well as cognitive and motor impairments in affected children. Therefore, early diagnosis through advanced screening techniques is vital for improving patient outcomes and quality of life.

A Quantitative First Passage Time Model for Tubular Microfluidic Immunoassays.

Solid-phase immunosorbent reactions, such as ELISA, are widely used for detecting, identifying, and quantifying protein markers. However, traditional centimeter scale well-based immunoreactors suffer from low surface-to-volume (S/V) ratios, leading to large sample consumption and a long assay time. Microfluidic technologies, particularly tubular microfluidic immunoreactors, have emerged as promising alternatives due to their high S/V ratios.

Atomic-Level Tin Regulation for High-Performance Zinc-Air Batteries.

The trade-off between the performances of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) presents a challenge in designing high-performance aqueous rechargeable zinc-air batteries (a-r-ZABs) due to sluggish kinetics and differing reaction requirements. Accurate control of the atomic and electronic structures is crucial for the rational design of efficient bifunctional oxygen electrocatalysts. Herein, we designed a Sn-Co/RuO trimetallic oxide utilizing dual-active sites and tin (Sn) regulation strategy by dispersing Co (for ORR) and auxiliary Sn into the near-surface and surface of RuO (for OER) to enhance both ORR and OER performances.

Sonodynamic Therapy by Reactive Oxygen Species Generation-Responsive Pseudo-Semiconducting Polymer Nanoparticles Combined with a Fibroblast Growth Factor Receptor Inhibitor for Enhancing Immunotherapy in Bladder Cancer.

Sonodynamic therapy, a treatment modality recently widely used, is capable of disrupting the tumor microenvironment by inducing immunogenic cell death (ICD) and enhancing antitumor immunity during immunotherapy. Erdafitinib, an inhibitor of the fibroblast growth factor receptor, has demonstrated potential benefits for treating bladder cancer. However, Erdafitinib shows effectiveness in only a small number of patients, and the majority of patients responding positively to the medication have "immune-cold" tumors.
