The Hypothesis of Trace Elements Involvement in the Coronary Arteries Atherosclerotic Plaques' Location.

: Coronary artery disease (CAD) is a chronic inflammatory disease with multiple well-known risk factors. Although epidemiological studies report improvements in classical CAD risk-factor control, except for diabetes and obesity, cardiovascular diseases remain the leading causes of morbidity and mortality in the current population. The question regarding the atherosclerotic plaque location in particular arteries remains unanswered.

Do probiotics and iron supplementation have any impact on element distribution in rat kidneys? - bioimaging by laser ablation inductively coupled plasma mass spectrometry.

This study investigates the influence of multistrain probiotics and iron supplementation on the distribution and interaction of trace elements in the kidneys of Wistar rats using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) bioimaging. Forty 6-week-old female Wistar rats were divided into five groups, each fed an AIN-93 M diet with varying additions or deficiencies of iron and probiotics, which included a control, an iron-deficient diet, an iron-deficient diet with probiotics, an iron-deficient diet with iron supplementation, and an iron-deficient diet with both probiotics and iron supplementation. The obtained two-dimensional maps of the distribution of elements reveal distinct locations of Cu, Fe, Mn, and Zn in specific tissues of rat kidneys.

Distinct cellular uptake patterns of two anticancer unsymmetrical bisacridines and their metabolic transformation in tumor cells.

Unsymmetrical bisacridines (UAs) represent a novel class of anticancer agents. Their high cytotoxicity towards multiple human cancer cell lines and inhibition of human tumor xenograft growth in nude mice signal their potential for cancer treatment. Therefore, the mechanism of their strong biological activity is broadly investigated.

What Can We Learn from the Scalp Hair's Trace Element Content? The Relationship with the Advancement of Coronary Artery Disease.

: Multiple risk factors for coronary artery disease have been identified without answering one of the leading questions related to the extent of the involvement of the epicardial arteries. Trace elements are involved in various stages of atherosclerotic lesion formation and may play a significant role in the advancement of coronary artery disease. : A total of 157 (92 (59%) men and 65 (41%) women) patients with a median age of 71 (65-75) years presenting with chronic coronary syndrome were enrolled in the prospective single-center analysis.

Are Hair Scalp Trace Elements Correlated with Atherosclerosis Location in Coronary Artery Disease?

Coronary artery disease is among the leading current epidemiological challenges. The genetic, clinical, and lifestyle-related risk factors are well documented. The reason for specific epicardial artery locations remains unsolved.
