Imazethapyr-Induced Inhibition of Arabidopsis Root Growth Associated with Disrupting Auxin Signal to Alter Cell Wall Remodeling.

Imazethapyr, a widely used herbicide, exhibits a long persistence in soils and can cause injury to rotational crops. Here, we discovered that imazethapyr inhibits primary root elongation in Arabidopsis by inhibiting cell division and expansion rather than damaging the organization of root meristem. Integration of transcriptomic and metabolomic analysis revealed that imazethapyr downregulated multiple genes related to cell wall loosening and modification, leading to increased cell wall thickness and inhibited cellular expansion in Arabidopsis roots.

Analysis of status quo and influencing factors of oral health literacy among the elderly in Hangzhou.

Human adipose-derived multipotent stromal cells enriched with IL-10 modRNA improve diabetic wound healing: Trigger the macrophage phenotype shift.

Diabetic wounds present a significant challenge in regenerative medicine due to impaired healing, characterized by prolonged inflammation and deficient tissue repair, primarily caused by a skewed pro-inflammatory macrophage phenotype. This study investigates the therapeutic potential of interleukin-10 (IL-10) chemically modified mRNA (modRNA)-enriched human adipose-derived multipotent stromal cells (hADSCs) in a well-established murine model of diabetic wounds. The modRNAs used in this study were chemically modified using N1-methylpseudouridine-5'-triphosphate (m1Ψ) by substituting uridine-5-triphosphate.

Here, we discussed surgical techniques based on our previous experience with facial artery perforator (FAP)-based facial defect reconstruction.

Carbon nitride dots do not impair the growth, development, and telomere length of tadpoles.

Carbon nanoparticles, or carbon dots, can have many beneficial uses. However, we must consider whether they may have any potential negative side effects on wildlife or the ecosystem when these particles end up in wastewater. Early development stages of amphibians are particularly sensitive to contaminants, and exposure to carbon dots could disrupt their development and cause morbidity or death.

Advancing glioblastoma imaging: Exploring the potential of organic fluorophore-based red emissive carbon dots.

Over time, the interest in developing stable photosensitizers (PS) which both absorb and emit light in the red region (650 and 950 nm) has gained noticeable interest. Recently, carbon dots (CDs) have become the material of focus to act as a PS due to their high extinction coefficient, low cytotoxicity, and both high photo and thermal stability. In this work, a Federal and Drug Association (FDA) approved Near Infra-Red (NIR) organic fluorophore used for photo-imaging, indocyanine green (ICG), has been explored as a precursor to develop water-soluble red emissive CDs which possess red emission at 697 nm.

Investigation into Red Emission and Its Applications: Solvatochromic N-Doped Red Emissive Carbon Dots with Solvent Polarity Sensing and Solid-State Fluorescent Nanocomposite Thin Films.

In this work, a NIR emitting dye, -toluenesulfonate (IR-813) was explored as a model precursor to develop red emissive carbon dots (813-CD) with solvatochromic behavior with a red-shift observed with increasing solvent polarity. The 813-CDs produced had emission peaks at 610 and 698 nm, respectively, in water with blue shifts of emission as solvent polarity decreased. Subsequently, 813-CD was synthesized with increasing nitrogen content with polyethyleneimine (PEI) to elucidate the change in band gap energy.

Nano-carrier for gene delivery and bioimaging based on pentaetheylenehexamine modified carbon dots.

Carbon dots (CDs) have attracted much attention due to their excellent properties and applications, especially the use for gene delivery.

Therefore, in this study, the potential to apply CDs as a non-viral vector for gene delivery was investigated.
