Cytokine Expression and Cytolytic Effect of Natural Killer Cells are Suppressed in Septic Shock.

Septic shock is the most severe stage of sepsis. How immune dysregulation contributes to the pathogenesis of septic shock has not been thoroughly understood. In the current research, the phenotype and function of circulating natural killer (NK) cells of septic patients were characterised.

A MOF-derived flower-shaped CeCo-oxide as a multifunctional material for high-performance lithium-ion batteries and supercapacitors.

Precursor method is a well-known technology for preparing certain functional materials. In this work, a novel 3d-4f bimetallic organic framework, denoted as 45MCeCo (45 M representing 4,5-imidazole dicarboxylic acid), was successfully synthesized via a hydrothermal technique. The compound thus obtained has the molecular formula of CHCeCoNO.

Multifunctional Carbon Dots-Based Fluorescence Detection for Sudan I, Sudan IV and Tetracycline Hydrochloride in Foods.

Sudan dyes are strictly prohibited from being added to edible products as carcinogens and tetracycline hydrochloride (TC) remaining in animal-derived food may cause harm to the human body. Therefore, it is necessary to establish a high-sensitivity, simple and convenient method for the detection of Sudan dyes and TC in foods for safety purposes. In this work, multifunctional blue fluorescent carbon dots (B-CDs) were prepared by a one-step hydrothermal synthesis using glucose as the carbon source.

Dezocine Has the Potential to Regulate the Clinical and Biological Features of Tumors.

Cancer is the second leading cause of death following ischemic heart disease in the world and the primary clinical, social and economic burden. Surgical resection is the main measure for the treatment of the vast majority of solid tumors. However, the recurrence and metastasis of tumors occur at different periods after surgery in many cases undergoing radical tumor surgery, which is the main cause of death of tumor patients.

Ultralow Thermal Conductivity and High Thermoelectric Performance in AgCuTeSe through Isoelectronic Substitution.

In this paper, we report a series of polycrystalline AgCuTeSe samples with high thermoelectric performance. X-ray photoelectron spectroscopy data suggest the observation of Ag, Cu, Te, and Se states of Ag, Cu, Te, and Se. Meanwhile, the carrier concentration of the obtained p-type samples changes from 9.

The effect of n-π* electronic transitions on the N photofixation ability of carbon self-doped honeycomb-like g-CN prepared microwave treatment.

Light harvesting is an important part of the photocatalysis process. In this work, carbon self-doped honeycomb-like g-CN with outstanding N photofixation ability was prepared microwave treatment. XRD, N adsorption, UV-Vis, SEM, XPS, ESR and PL were used to characterize the as-prepared catalysts.

Structural and functional studies on three alginate lyases from Vibrio alginolyticus.

To date, several microorganisms that can metabolize alginate have been characterized. In these microorganisms, a class of enzymes called alginate lyases (Alys) catalyze the depolymerization of alginate into oligomers via an endolytic β-elimination reaction. But it is not clear how these lyases differ on their enzymological functions or their divisions of labor.

Prediction of peptide drift time in ion mobility mass spectrometry from sequence-based features.

Background: Ion mobility-mass spectrometry (IMMS), an analytical technique which combines the features of ion mobility spectrometry (IMS) and mass spectrometry (MS), can rapidly separates ions on a millisecond time-scale. IMMS becomes a powerful tool to analyzing complex mixtures, especially for the analysis of peptides in proteomics. The high-throughput nature of this technique provides a challenge for the identification of peptides in complex biological samples.

[Pharmacognostic identification of Rodersia aesculifolia].

Objective: To establish pharmacognostical methods of Rodersia aesculifolia.

Methods: Macroscopical, microscopic and physicochemical identification were used to authenticate this crude drug, and the identification characteristics were studied.

Results: There were some palea on the rhizoma superior extremity and some white flare dot on transverse section.
