A Follow-Up Study on the Effects of Football Scrimmages on Blink Reflex Parameters in Division I Athletes

Neurology

Abstract

The objective was to conduct a follow-up study to access the effects of football scrimmages on blink reflex parameters using the Eyestat. Eyestat is a noninvasive diagnostic tool measuring changes in blink reflex parameters. Prior research cited significant differences in various blink reflex parameters between active play, concussion, and baseline; however, the number of subjects for the active play population was small and within a football practice versus a football scrimmage. Fifty-eight division I male football players, between the ages of 18 and 22 years, participated in multiple sessions during a 3 week period of football scrimmages and a spring game. In addition, a subgroup of these subjects (N = 20) provided a minimal of 3 or more scans throughout the study. During various points of play, subjects completed the blink test and had heart rates assessed. For the blink test, subjects placed their face against the apparatus, which directed a puff of air to the corner of the subject's eye to stimulate the blink. Five puffs were administered in a random fashion over a 20-second period while videography captured and recorded the blink. The results of the study cited significant differences in heart rates above 55% of predicted...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.
