Abstract

To compare blood flow velocity measurements obtained with two different linear probes (7.5 MHz and 12 MHz). CDI measurements were performed in 31 eyes of 19 individuals with a 12 MHz and a 7.5 MHz probe. Measurements were taken in the ophthalmic artery (OA), central retinal artery (CRA), temporal short posterior ciliary arteries (TSPCA), and nasal short posterior ciliary arteries (NSPCA). With each probe, three measurements of each vessel were obtained, and end-diastolic velocity (EDV), peak systolic velocity (PSV), and resistance index (RI) were calculated. For EDV, the variation among replicates with the 7.5 MHz probe was between 13.99% and 19.51% and with the 12 MHz probe between 15.40% and 23.17%. For PSV, the variation among replicates was between 5.16% and 9.98% and between 6.58% and 10.71%, respectively with each probe. For RI, the variation among the replicates was between 3.10% and 8.97% and between 3.93% and 10.16%, respectively with each probe. The variation between probes was between 15.02% and 23.07% for EDV, between 10.72% and 13.24% for PSV, and between 4.27% and 6.05% for RI. The difference between estimated means was only significant for EDV in the TSPCA (P = 0.019), PSV in the TSPCA (P = 0.0002), as well as NS...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.
