The influence of age on reactive hyperaemia in the human calf: a study with strain gauge plethysmography

Scandinavian Journal of Clinical and Laboratory Investigation

Abstract

Postischaemic reactive hyperaemia in the calf was investigated by strain gauge plethysmography in four groups of ten subjects. The mean age of the different groups was 6, 13, 24 and 57 years respectively. Basal calf flow, repayment and recovery time in the 6-year-old children were greater than in the other groups, which may be related to a higher metabolic rate in young children. Maximal flow in the four groups was not significantly different, which indicates that the arteriolar response to circulatory arrest is not altered by increasing age. The cause of delay in maximal flow in the group of 6-year-olds is not clearly understood. Basal and postischaemic lowest peripheral resistance increased with age, which is probably caused by changes of the arterioles due to ageing and possibly inactivity. The fall in peripheral resistance induced by 3 min of ischaemia was positively correlated with mean blood pressure. This may be due to a greater net reduction in blood pressure during ischaemia, which brobably elicits a stronger myogenic response of the vessel wall. It is concluded that in clinical use of the reactive hyperaemia test in the calf, the influence of age is of minor importance, whereas postischaemic peripheral resistance is a...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.
