Abstract

Since 1966 the School Dental Clinic of St. Gall has been in charge of preventive dentistry and treatment of school and kindergarten children. For children from kindergarten and the 1st level of primary school, the caries incidence rate was established in percentages. For those of 14 years of age, the DFM-T index (including 2 bit-wings) was determined. For the 14-year-old children the average number of carious, filled and extracted teeth (DMF-teeth) decreased as follows: 1974 DFM-T = 7.0; 1978 DMF-T = 5.0; 1982 DMF-T = 3.0; 1987 DMF-T = 2.7; 1991 DMF-T = 1.1. The percentage of children with a healthy natural dentition in this age group was approximately 40% in 1991. The number of extractions of permanent teeth dropped 15 times, the number of required tooth fillings up to 5 times. Whilst children of 14 years of age in 1991 showed a minimum of carious lesions, the caries prevalence of kindergarten children and those of 1st level primary school increased slightly (partly due to influx of foreigners). This fact draws attention to the significance of a uniform, continuous and systematic prevention in the future.

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.
