Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

高铁酸钾与UV-vis/TiO₂协同氧化效应的研究

Gongye shui chuli, 2007
为研究高铁酸钾与紫外-可见光/二氧化钛(UV-vis/TiO2)光催化的协同氧化效应，以氨氮为目标物，研究了高铁酸钾、UV-vis/TiO2光催化以及高铁酸钾与UV-vis/TiO2光催化联用对水中氨氮的去除效果。结果表明，在高铁酸钾与UV-vis/TiO2光催化联用的条件下，在pH=8.0，温度为室温，反应时间为30min，氨氮质量浓度50mg/L，高铁酸钾、TiO2投加质量浓度分别为20、200mg/L时，水中氨氮的去除率为97.5%，比单独的高铁酸钾或UV-vis/TiO2最大去除率分别提高了22.

Color and Near‐Infrared Reflectance Covary in Distinct Ways Across Taxa

Ecology and Evolution
Solar radiation reaching Earth spans 300–2500 nm, covering ultraviolet (UV), visible (Vis), and near‐infrared (NIR) wavelengths. Its reflectance is critical for animal signaling, camouflage, and thermoregulation, likely leading to selective trade‐offs ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

FEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Adjusting UV‐Vis Spectrum of Alizarin by Insertion of Auxochromes

ChemistryOpen
First synthesized in 1868, alizarin became one of the first synthetic dyes and was widely used as a red dye in the textile industry, making it more affordable and readily available than the traditional red dyes derived from natural sources.
