Abstract

We determined gastrin concentrations in newborns and their mothers both before and during lactation. Twenty-five women who had uncomplicated pregnancies with normal vaginal delivery of healthy infants at term participated in the study. Twelve preterm neonates with low birth weight (LBW) were also studied. Gastrin levels were determined by radioimmunoassay in amniotic fluid and in serum of both the neonates and their mothers at birth and during breast-feeding. Serum levels of gastrin and prolactin (PRL) were measured in the mothers before and after tactile self-stimulation of the breast. In normal newborns, gastrin levels in cord sera were significantly higher than levels in maternal blood and amniotic fluid at birth. However, gastrin cord sera in LBW newborns was lower than in the normal neonates. Nursing resulted in an increment of serum gastrin levels in the infants and mothers; this rise was similar in the 3 postpartum weeks tested. Tactile stimulus of the mother's nipple resulted in increases of both gastrin and PRL. Newborns at term show significantly higher gastrin levels than do LBW neonates, which may indicate differences in development of the gastrointestinal system. Breast-feeding induced gastrin secretion in both mot...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.
