Abstract

The aims of this study were to investigate whether: (i) lactating women had an elevated plasma level of motilin; (ii) there was a correlation between the plasma motilin level and the motilin level in breast milk in lactating women; and (iii) there was a difference in motilin levels between the colostrum and mature human milk in a controlled postprandial state. Twenty control women and 18 lactating women were enrolled in this study. All samples were drawn in a controlled postprandial state. The concentration of motilin was measured using radioimmunoassay. The plasma motilin level in lactating women was 434 +/- 180 pmol/L on the fifth day after delivery and 450 +/- 204 pmol/L on the 42nd day after delivery (P > 0.05). Both of these values were significantly higher than those in the control women (231 +/- 48 pmol/L, P < 0.05). The motilin level in human milk in the controlled postprandial state was 161 +/- 56 pmol/L on the fifth day and 154 +/- 60 pmol/L on the 42nd day after parturition (P = 0.7). Although there was motilin in the breast milk and an elevated plasma level of motilin in the lactating women, there was no correlation in motilin level between the blood and the breast milk. Motilin is elevated in the blood of lactating...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.
