Fluorescent probe for imaging NH in plants, food, and living cells and for quantitative detection of NH in soil and water using a smartphone.

Hydrazine is volatile and highly toxic, causing severe harm to water, soil, air, and organisms. Therefore, real-time detection and long-term monitoring of hydrazine are crucial for environmental protection and human health. Herein, an "OFF-ON" fluorescent probe 5-((10-ethyl-2-methoxy-10 H-phenothiazin-3-yl)methylene)-2,2-dimethyl-1,3-dioxane-4,6-dione (MPD) for hydrazine detection through a nucleophilic addition reaction was developed.

A signal recognition particle receptor gene from the sea cucumber, Apostichopus japonicas.

The signal recognition particle (SRP) system delivers approximately 30% of the proteome to the endoplasmic reticulum (ER) membrane. SRP receptor alpha (SRα) binds to SRP for targeting nascent secreted proteins to the ER membrane in eukaryotic cells. In this study, the SRα homologous gene was identified in the sea cucumber, Apostichopus japonicus (AjSRα).

Analysis of the Curative Effect of the Anterior Approach to the Lower Cervical Spine for Cervicothoracic Spinal Tuberculosis.

Background: The purpose of this study was to explore the clinical effect of the anterior approach to the lower cervical spine for cervicothoracic spinal tuberculosis (CTSTB).

Methods: A total of 8 patients (6 males and 2 females) with CTSTB diagnosed by imaging examination and γ-interferon test, underwent the first stage lesion removal, bone grafting and internal fixation through the anterior approach to the lower cervical spine, were studied. Then, the clinical efficacy was evaluated using statistical analysis based on the materials about the Cobb angle of kyphosis, visual analog scale (VAS), Frankel grade, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).

Theoretical studies on structures and spectroscopic properties of self-assembled bis(2,4,8,10-tetramethyl-9-methoxycarbonylethyldipyrrin-3-yl)methane with Co(II).

We report a combined experimental and computational study of the large self-assembly complex (CoL)(2) [L= bis(2,4,8,10-tetramethyl-9-methoxycarbonylethyldipyrrin-3-yl)methane] containing 172 atoms. An extensive density functional theory (DFT) and time-dependent DFT study of this complex in gas phase and in CH(2)Cl(2) solution was performed, investigating the effect of substitutions of methyl and methyl propionate on the electronic structure and optical properties of this complex. The calculated IR and Raman spectra are in excellent agreement with the experiment, thus allowing a detailed assignment of the vibrational absorption bands.
