Abstract

Exposure to chloroform (CHCl3) in indoor swimming pool swimmers. CHCl3 presence has been evidenced many times in water and air of indoor pools as a consequence of water chlorination with sodium hypochlorite or other chlorinated disinfectants. In previous studies CHCl3 in environmental air appeared at a high concentration within one meter over the surface of the water and was correlated to the number of swimmers inside the pool. CHCl3 has also been evidenced in blood serum samples of people present at the swimming pool, at different levels depending on: the concentration in the environmental air, the intensity and the length of the sport activity and the number of swimmers in the pool. At the end of the swimming session CHCl3 concentration tends to lower quickly and usually is no longer detectable within half an hour. Other studies have evidenced CHCl3 in breath samples (alveolar air) of a volunteer subject who swam one hour every day in an indoor pool in Modena. The spirometric parameters of the same subject were evaluated in order to estimate his CHCl3 uptake during time spent at the swimming pool, both resting and swimming in different modes. In the present paper the A.A. report data about CHCl3 exposure, intake and uptake bi...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.
