Abstract

Using human volunteers the metabolic alterations during standardized nutrition (2,000 kcal/day = 8,400 kJ/day) and during energy-reduced nutrition (1,180 kcal/day = 6,000 kJ/day) with a carbohydrate-containing semiformula diet were investigated. Evaluating the concentrations of blood glucose, serum insulin and serum-free fatty acids it was demonstrated that the nutrition-induced metabolic alterations between the meals (i.e. hyperinsulinemia, low fatty acid concentrations) were not normalized in the group using the standardized diet. In contrast in the group with energy-reduced diet (240 kcal/meal = 1,000 kJ) the concentrations of serum-free fatty acids and of serum insulin reached the fasting values before the next meal. The concentrations of triglycerides and of urea show merely slight reactions following the meals. A rise in concentration of these two parameters is found after the last meal. It is concluded that with the standardized diet the absorption phase following the meals lasts for at least 4 h, whereas the absorption is ended within 2-3 h following the energy-reduced meal. The results of these investigations are interpreted as follows. During a carbohydrate-containing semiformula diet the metabolic mechanisms includin...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.
