Shaping electrospray plume with convergent sound beams

iScience
Summary: Electrospray ionization (ESI) is one of the mainstream ionization techniques for mass spectrometry (MS) nowadays. Here, we present a new variant of ESI-MS setup, in which an electrospray emitter points to the mass spectrometer’s orifice while ...

Nanoparticle‐Mediated CXCL12–CXCR4 Inhibition Reprograms Macrophages and Suppresses Gastric Carcinoma

Advanced Science, EarlyView.
Molecular mechanism study of self‐assembled M2pep‐Cs NPs/Plerixafor nanoparticles in targeting MΦ reprogramming by regulating the CXCL12–CXCR4 signaling pathway to enhance immune recognition and clearance of GC (Created by BioRender). Abstract Gastric carcinoma (GC) remains a major global health challenge, requiring novel therapeutic approaches.

Avaliação da eficiência das técnicas ESI-MS e ATR/FTIR na determinação de adulteração de BX com querosene e óleo residual

Química Nova, 2011
Direct infusion electrospray ionization mass spectrometry in the negative ion mode, ESI(-)-MS and Fourier transform infrared spectroscopy (FTIR) were used together with partial least squares (PLS) as a tool to determine B3 adulteration (B3 - mixture of 3%

Theta-Glass Capillaries in Electrospray Ionization: Rapid Mixing and Short Droplet Lifetimes

Analytical Chemistry, 2014
Double-barrel wire-in-a-capillary electrospray emitters prepared from theta-glass capillaries were used to mix solutions during the electrospray process. The relative flow rate of each barrel was continuously monitored with internal standards.

Inhibition of Phosphodiesterase 10A by MP‐10 Rescues Behavioral Deficits and Normalizes Microglial Morphology and Synaptic Pruning in A Mouse Model of FOXP1 Syndrome

Advanced Science, EarlyView.
We demonstrate that Foxp1± mice, modeling FOXP1 haploinsufficiency, exhibit behavioral deficits, striatal neuroinflammatory changes including altered microglial complexity and synaptic pruning, and markedly reduced Pde10a expression. Pde10a inhibition starting immediately after birth restores Foxp1± behavior, microglial morphology, and pruning ...

Characterization and Determination of the Alkaloid Metabolites of Evodiae fructus in Rat Urine by Liquid Chromatography-Tandem Mass Spectrometry Detection

Molecules, 2011
The lack of authentic standards limits the quantitative analysis of herbal drugs in biological samples. This present work demonstrated a practicable assay of herbs and their metabolites independent of the availability of authentic standards.

Advanced Microfluidics for Single Cell‐Based Cancer Research

Advanced Science, EarlyView.
Cutting‐edge microfluidic platforms are transforming single‐cell cancer research. This review highlights advanced technologies, from droplet microfluidics to tumour‐chips, that enable functional and spatial single‐cell analyses. By integrating biosensing, immune components, and patient‐derived materials, these systems offer new insights into tumour ...
