Comparison of Extraction Methods for the Quantification of Phytohormones from Tomato Fruits and Leaves by LC-MS/MS

The paper compares three phytohormone extraction methods in tomato tissues, finding that solid-phase extraction methods do not consistently outperform a simpler single-phase method in reducing matrix effects.

Ammonium retention by Amberlite IRC-748 resin: useful for concentration assessments

The paper assesses ammonium retention by Amberlite IRC-748 resin, finding it removes metal ions but co-adsorbs NH4+ with concentration-dependent losses, affecting high-precision N analysis.

A study of different pre-treatment methods for cigarettes and their aroma differences

The paper compares different pre-treatment methods for cigarettes to identify aroma differences using GC-MS and sensory evaluation.

Rapid and precise quantification of lymphocyte iron content by single cell inductively coupled plasma mass spectrometry

The paper quantifies single-cell iron content in lymphocytes using ICP-MS and links iron levels to cellular activation and function.

Glucose uptake in mammalian cells measured by ICP-MS

The paper develops a method to measure 13C-labeled glucose and rubidium in biological samples using ICP-MS, demonstrating its ability to detect glucose uptake in skeletal muscles.

"Monoclonal-type" plastic antibodies for SARS-CoV-2 based on Molecularly Imprinted Polymers

This paper develops 'monoclonal-type' plastic antibodies based on Molecularly Imprinted Polymers (MIPs) that selectively bind SARS-CoV-2 spike protein to block infection.

Multi-Neuromodulator Measurements across Fronto-Striatal Network Areas of the Behaving Macaque using Solid-Phase Microextraction

The paper uses SPME to measure multiple neuromodulators in macaque brains during behavior, finding glutamate concentrations much higher than dopamine and acetylcholine.
