The Effect of Dicarboxylic Acid Structure on the Plasticizing Ability of Its Ester.

Polyvinyl chloride (PVC) belongs to the most widely used group of thermoplastics. Most of the market for PVC products belongs to plasticized compositions. Plasticizers are the most demanded additives in the polymer industry.

Exploring serum trace element shifts: Implications for cervical intraepithelial neoplasia.

Background: Cervical intraepithelial neoplasia (CIN) represents a premalignant state presumably related to perturbations in circulating levels of trace elements.

Materials And Methods: Employing inductively coupled plasma mass spectrometry (ICP-MS), we quantified essential and toxic trace elements in the sera of 60 women diagnosed with CIN and 60 age-matched healthy counterparts.

Results: Our investigation revealed a noteworthy higher levels in serum of Mn, Zn, and Pb, as well as lower levels in Ni, Se, Rb, and Mo levels within the CIN cohort.

Changes of Target Essential Trace Elements in Multiple Sclerosis: A Systematic Review and Meta-Analysis.

(1) Background: Multiple sclerosis (MS) is a chronic, complex, and demyelinating disease closely associated with altered levels of trace elements. Although the first studies into the role of trace elements in MS were published in the 1970s, for five decades it has remained unknown whether trace elements can be part of this heterogeneous neurological disease. (2) Materials and methods: To drive toward at a potential solution, we conducted a systematic review and meta-analysis to elucidate whether there were differences in circulating levels of neurologically important essential trace elements (Zn, Fe, Co, Cu, Mn, and Se) between MS cases and controls.

The cathodically pretreated boron-doped diamond electrode as an environmentally friendly electrochemical tool for the detection and monitoring of mesotrione in food samples.

Excessive pesticide use can harm human health, making it essential to develop new techniques to monitor hazardous pesticides in food. Our study focuses on detecting mesotrione (MST) using an unmodified boron-doped diamond (BDD) electrode. This was the first application of cathodically pretreated BDD electrode for the detection of MST, based on its oxidation at a high potential value of +1.

Essential trace element levels in multiple sclerosis: Bridging demographic and clinical gaps, assessing the need for supplementation.

Background: Multiple sclerosis (MS) is a chronic demyelinating disorder intricately linked to perturbations in trace element levels. While previous studies have explored circulating trace elements in a limited sample, understanding the impact of demographic and clinical variables on the elemental profile within a larger cohort remains elusive.

Methods: This study aimed to evaluate essential trace elements (Cr, Mn, Co, Cu, Zn, and Se) in the sera of 215 MS patients compared to a meticulously matched control group of 100 individuals with similar gender and age.
