Abstract

Volume expansion for the establishment of normal to slightly hyperdynamic systemic circulation has become part of a standard concept in the treatment of septicemic patients. The goal is an improvement of microcirculation with beneficial effects on tissue oxygen supply. This study investigates the effect of hydroxyethyl starch solution (HES 6%: mean molecular weight = 40,000) versus ringer's solution on tissue oxygen tensions in human skeletal muscle during periods of septicemia in 10 mechanically ventilated ICU-patients. Measurement of tissue oxygen tension was achieved by a polarographic pO2-sensitive flexible probe. After computer assisted analysis pO2-histograms were calculated out of 200 single pO2-values measured consecutively within a time period of 4 min. Infusions of 500 ml ringer's solution or 500 ml HES were given over 60 min in each patient in a randomized order. The second infusion was begun when the pO2-histogram had reproducibly regained control values as measured before treatment. Measurements were made every 30 min after starting the infusion for a total period of 150 min. As a result the median pO2 improved by 24.5% 90 min after the infusion of HES was begun with a simultaneous significant (30 to 150 min; p les...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.
