Lead, copper, zinc, and magnesium content in hair of children and young people with some neurological diseases

Biological Trace Element Research

Abstract

The lead, copper, zinc, and magnesium levels of scalp hair taken from 153 children aged 1-15 yr and young people (16-18 yr) with selected neurological disorders (hyperexcibility, loss of consciousness, and epileptiform convulsions of an unknown origin, etc.), were measured using the atomic absorption spectrometry method and then compared with a control group of healthy children (n = 108). The research indicated significantly reduced mean levels of magnesium in the hair of children suffering from selected neurological diseases (in children aged 11-15 yr of age, above 30%; up to 5 yr of age, nearly 30%; the differences were statistically significant at p < 0.05) and slightly decreased mean levels of copper (differences statistically significant at p < 0.05, particularly in the 11 to 15-yr category). Differences in zinc levels in hair were inconsiderable (not statistically significant in any age groups). The lead level in the hair of the above-mentioned group of children was exceeded in relation to the control group (a statistically significant difference at p < 0.05 for the total group). A more than twofold decrease in the mean value of the Mg/Pb ratio (and a nearly 30% decrease in the value of the Mg/Zn ratio) in the hair of chi...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
