Article Abstract

Benzo[a]pyrene (BaP), known for its carcinogenic and mutagenic properties, is a marker of polycyclic aromatic hydrocarbons (PAHs). This study aimed to investigate the effect of partially replacing sodium chloride with different calcium salts (calcium chloride, calcium gluconate, calcium citrate, and calcium lactate) on BaP formation in barbecued pork sausages. The results revealed that all four calcium salts inhibited BaP formation in barbecued pork sausages (P < 0.05). Specifically, calcium gluconate showed the most significant effect on BaP inhibition, with an inhibition rate of 61.82 %. Furthermore, calcium salts were found to inhibit lipid oxidation in barbecued pork sausages while promoting the Maillard reaction. Further validation experiments used resveratrol and sodium sulfite as lipid oxidation and Maillard reaction inhibitors, respectively. These results indicated that lipid oxidation is the primary pathway for BaP production in barbecued pork sausage and that the addition of calcium salts can effectively block this process.

An idea of using ion-exchanger salt containing optically active cations to prepare ion-selective membranes is proposed. Although the presence of an ion-exchanger in the composition of neutral ionophore based sensors is necessary, the choice of available salts for cation-selective sensors preparation, is usually limited to sodium or potassium compounds. In this work we propose application of an alternative salt, using a cation optically active both in absorption and emission mode as a mobile one.

Lead is a toxic heavy metal, which accumulates in the soil and is readily absorbed by plant roots. The uptake of toxic elements by crops is a serious threat to human health. For this reason, it is important to prevent the incorporation of heavy metals into the food chain.

: Vitamin D receptor (VDR) agonists are commonly used in clinical practice for their roles in calcium regulation and potential benefits in various diseases. However, their safety profiles, particularly for compounds available as food supplements, remain underexplored in real-world settings. This study aimed to analyze the safety profiles of VDR agonists using the EudraVigilance database, focusing on adverse drug reactions (ADRs) reported between 1 January 2004 and 23 June 2024.

In this paper, the enhancement of thermochemical energy storage by alkali metal chloride salts-doped Ca-based sorbents is revealed by experiments and DFT calculations. The results indicate that NaCl and KCl doping increases the reaction rate and cycle stability. Compared to CaO, the conversion of NaCl-CaO and KCl-CaO after one cycle is increased by 59.

: Nephrocalcinosis (NC) is a common condition characterized by the deposition of calcium salts in the kidneys of very preterm infants due to tubular immaturity, intensive treatment and nutritional supplements. However, optimal vitamin D supplementation remains unclear. In most patients, NC spontaneously resolves within the first year of life, but long-term kidney function data are lacking.
