Abstract

We compared the iodine excretion and thyroid volumes in young students with or without continuous use of iodized salt in household. Students from five different Universities in Bavaria were evaluated on a voluntary basis. Exclusion criteria were age above 35 years, known thyroid illness except simple goiter, application of x-ray contrast medium within the last 6 months or other known exposure to high doses of iodine. The participants answered a questionnaire indicating permanent utilization of iodized salt for more than one year during all their meals, the intake of iodide tablets and eating in student cafeterias, offering meals that are prepared with iodized salt. Morning spot urine was drawn from each participant to measure creatinine correlated iodide excretion and thyroid volume was measured by ultrasound. In this study, 932 students could be included, mean age was 24 years, 501 females, 431 males. Chronic users of iodized salt were 75.9% (80.4% females, 70.5% males), 1.7% were on iodide tablets (200 micrograms/day) and 2.6% were on TSH suppressive therapy with thyroid hormones. The mean iodide excretion in chronic iodized salt users was 72.0 (+/- 68.7) micrograms/g creatinine compared to non-users 66.0 (+/- 65.4) microgram...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.
