Article Synopsis
  • A study was conducted to examine the impact of a low iron diet on arthritis progression in a mouse model, focusing on collagen-induced arthritis (CIA).
  • Male DBA/1 mice were divided into two groups: one fed a normal iron diet and the other a low iron diet, with arthritis monitored over 34 days after immunization.
  • Results showed mice on a low iron diet had less severe arthritis, lower serum levels of a key inflammatory regulator, and decreased red blood cell indices, indicating less iron absorption.

Colloidal nuclear magnetic resonance (cNMR) spectroscopy on inorganic cesium lead halide nanocrystals (CsPbX NCs) is found to serve for noninvasive characterization and quantification of disorder within these structurally soft and labile particles. In particular, we show that Cs cNMR is highly responsive to size variations from 3 to 11 nm or to altering the capping ligands on the surfaces of CsPbX NCs. Distinct Cs signals are attributed to the surface and core NC regions.

Lead halide perovskite (LHP) nanocrystals (NCs) have gathered much attention as light-emitting materials, particularly owing to their excellent color purity, band gap tunability, high photoluminescence quantum yield (PLQY), low cost, and scalable synthesis. To enhance the stability of LHP NCs, bulky strongly bound organic ligands are commonly employed, which counteract the extraction of charge carriers from the NCs and hinder their use as photoconductive materials and photocatalysts. Replacing these ligands with a thin coating is a complex challenge due to the highly dynamic ionic lattice, which is vulnerable to the commonly employed coating precursors and solvents.

Article Synopsis
  • The decline in liquid milk consumption in Western countries is being offset by a rise in processed dairy products and plant-based milk alternatives, which are frequently marketed as substitutes for cow's milk.
  • A study compared the nutritional content of 27 plant-based drinks to cow's milk, analyzing factors like protein, fat, vitamins, and minerals, as well as harmful residues such as glyphosate and arsenic.
  • The findings indicated that while soy drinks contained more protein and certain vitamins than milk, most plant-based alternatives were low in protein and did not match the nutrient profile and quality of cow's milk, highlighting the need for better fortification in these products.

Background: Whereas the dietary intake of industrial trans fatty acids (iTFA) has been specifically associated with inflammation, cardiovascular disease, and type 2 diabetes, understanding the impact of dietary fats on human health remains challenging owing to their complex composition and individual effects of their lipid components on metabolism. The aim of this study is to profile the composition of blood, measured by the fatty acid (FAs) profile and untargeted metabolome of serum and the transcriptome of blood cells, in order to identify molecular signatures that discriminate dietary fat intakes.

Methods: In a parallel study, the molecular effects of consuming dairy fat containing ruminant TFA (rTFA) or margarine containing iTFA were investigated.
