High end tidal CO2 association with blood pressure response to sodium loading in older adults

Abstract

To test the hypothesis that blood pressure of older adults with high resting end tidal CO2 (PETCO2) is sensitive to high dietary intake of sodium chloride. Forty-four Caucasian men and women, aged 41-79 years (mean +/- SEM 55.5 +/- 1.4), restricted their dietary intake of sodium chloride for 11 days and ingested sodium chloride capsules (an additional 190 mmol sodium/day) during the last seven of those days. On days 1, 4 and 11, resting PETCO2 and blood pressure were monitored for 25 min in the laboratory, followed by ambulatory blood pressure monitoring in the natural environment for 24 h. Overnight urine samples were obtained at days 4 and 11 to estimate excretion of sodium and of an endogenous digitalis-like factor (EDLF) that is sensitive to changes in plasma volume. Individual resting PETCO2 remained stable within and between laboratory monitoring sessions and was correlated with urinary excretion of the endogenous digitalis-like factor, both before and after the period of high sodium intake. The high-sodium diet was associated with increased urinary sodium excretion and body weight in all quartiles of PETCO2. The high-sodium diet produced significant increases in resting and in 24 h systolic blood pressures in the upper t...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.
