One-Pot Hydrothermal Method Preparation of Cerium-Nitrogen-Codoped Carbon Quantum Dots from Waste Longan Nucleus as a Fluorescent Sensor for Sensing Drug Rifampicin.

Currently, the large-scale application of carbon quantum dots (CQDs) is usually limited by their low quantum yield and detection limit. Herein, the abandoned longan nucleus was used as a carbon source to synthesize cerium-nitrogen-codoped carbon quantum dots (Ce/N-CQDs) with strong luminescence intensity. In this work, the fluorescent properties and fluorescent quantum yield of CQDs may be improved by the single cerium-doped carbon quantum dots (Ce-CQDs) and the single nitrogen-doped carbon quantum dots (N-CQDs).

A new fluorescence method for detection of famotidine based on polyethyleneimine-templated Ag nanoclusters.

A rapid, simple, inexpensive fluorescence analysis method for determination of famotidine based on polyethyleneimine (PEI)-capped Ag nanoclusters (PEI-Ag NCs) was developed. The study showed that addition of famotidine could cause efficient quenching of PEI-Ag NC fluorescence, as the presence of famotidine could cause aggregation of Ag NCs and quench its fluorescence. The sensitivity and selectivity of the method were investigated and experimental conditions such as buffer type, pH, temperature, and reaction time were optimized.

Mechanism of Follicular Helper T Cell Differentiation Regulated by Transcription Factors.

Helping B cells and antibody responses is a major function of CD4T helper cells. Follicular helper T (Tfh) cells are identified as a subset of CD4T helper cells, which is specialized in helping B cells in the germinal center reaction. Tfh cells express high levels of CXCR5, PD-1, IL-21, and other characteristic markers.

Hepatitis B core antigen upregulates B7-H1 on dendritic cells by activating the AKT/ERK/P38 pathway: a possible mechanism of hepatitis B virus persistence.

B7-H1 binding to programmed death-1 may deliver a coinhibitory signal to T cells that is involved in the regulation of T-cell activation and tolerance.
