Abstract

The primary objective of this study was to assess the acute effects for both cold and warm air running on pulmonary function testing and the diagnosis of exercise-induced bronchospasm (EIB). Subjects (n = 12, 8 men, 4 women) were distance runners (25.91 +/- 4.91 milesxwk) with mean age 30.2 +/- 5.1 years, mean height 179.0 +/- 11.5 cm, and mean weight 77.1 +/- 15.7 kg. Subjects first performed a maximal oxygen test on a motor-driven treadmill to assess Vo2max and maximal heart rate (MHR). On 2 subsequent days and within a 1-week time period, subjects ran 8 minutes in random order either on an outside 478.2-m course or on the treadmill at 6% grade. Speed was adjusted under both conditions to elicit 85-95% of MHR achieved on the Vo2max test. All tests were conducted in the month of January to maximize the potential for a cold climate. Pulmonary function test was performed immediately prerun, immediately postrun, and at 5, 10, 18, and 30 minutes postrun. There was no significant difference in any of the pulmonary function tests over time for cold vs. warm running (p > 0.05). Also, the pattern of change over time for the pulmonary function variables was not significantly different by condition (p > 0.05). Although group comparisons...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.
