Human fetal breathing and gross body activity relative to maternal meals during insulin-dependent pregnancy

Abstract

Measurement of the percentage incidence of fetal breathing and gross body movements as well as of maternal blood glucose concentration was carried out in 12 insulin-dependent diabetic pregnant women and 12 normal controls between 33 and 37 weeks of gestation. The observation period was related to the three meal times. In diabetics no diurnal variation in pre-prandial fetal breathing activity was observed whereas in normal controls fetal breathing incidence was significantly higher before evening dinner than before breakfast. Immediately following lunch and dinner, fetal breathing demonstrated a significantly lower incidence in diabetics than in normals. Since no significant difference in maternal blood glucose concentration was found between the two groups, it is suggested that other factors relative to carbohydrate metabolism may also be involved in the regulation of fetal breathing in diabetes. Fetal gross body activity in diabetics vs. normals did not differ essentially and demonstrated no correlation with the maternal blood glucose levels.

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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
