Interlaboratory comparison of the measurement of albumin in urine

Clinical Chemistry, 1991
Abstract Because of increased interest in the assay of albumin in urine and the sensitivity required to quantify concentrations associated with (a) increased risk of developing end-stage renal disease and cardiovascular disease among people with diabetes and (b) renal damage caused by exposure to nephrotoxic substances, we conducted a ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

The “PTB Ex Proficiency Testing Scheme” - Interlaboratory Comparisons in the Field of Explosion Protection

Chemical Engineering Transactions, 2016
The requirement of participation in interlaboratory comparisons was not sufficiently fulfilled by laboratories in the field of explosion protection (Ex-testing laboratories) due to a lack of proficiency testing programs.

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

MXene Bioinks for 3D Bioprinting: Design and Translation

Small, EarlyView.
This study establishes a comprehensive framework for MXene‐based bioinks in 3D bioprinting, highlighting the interplay between rheological engineering and electroactive hydrogels. By optimizing electrical percolation and mediated signaling, these formulations drive tissue‐specific biological outcomes and accelerated regeneration.

Harnessing the nonthermal effects of ultrasound for cancer treatment: From mechanisms to applications

Smart Molecules, EarlyView.
Nonthermal ultrasound transforms acoustic energy into diverse therapeutic bioeffects through cavitation, mechanical stimulation, and physicochemical activation. This review discusses how acoustic parameters, biological mechanisms, and responsive materials interact to influence nonthermal ultrasound‐enabled cancer therapies. Mechanism‐guided engineering

Harmonisation of methane isotope ratio measurements from different laboratories using atmospheric samples [PDF]

Atmospheric Measurement Techniques
Establishing interlaboratory compatibility among measurements of stable isotope ratios of atmospheric methane (δ13C-CH4 and δD-CH4) is challenging. Significant offsets are common because laboratories have different ties to the VPDB or SMOW-SLAP scales ...

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

Environmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.
