Abstract

Heart rate, respiratory rate, and ability to maintain body temperature were evaluated in six infants born to rhesus monkeys that had been fed a low protein diet throughout pregnancy. All infants were kept in incubations equipped with a "servo" control thermal unit that maintained the infants' skin temperature at 37.0 C (98.6 F). The thermal units were disconnected and the infants were exposed to room temperature (approximately 27 C) for 6-hr periods each day after 24 hr of age in order to determine the efficiency of thermal control mechanism. The thermal servo control units were "on" for a longer period of time in experimental animals than in control animals during the first 24 hr of life. Infants from mothers fed the low protein diets were also less able to maintain their own body temperatures after exposure to room temperature. This function was seriously compromised in two of the six experimental infants. The compromised temperature control mechanism seen in these infant monkeys is a serious and potentially lethal side-effect of protein-calorie malnutrition during pregnancy. The possible relationship of inadequate maternal nutrition to the inefficient thermal mechanism of certain "high risk" human newborns should be reevalua...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.

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.

Systemic Juvenile Idiopathic Arthritis

Systemic juvenile idiopathic arthritis is a rare rheumatic disease that affects children. Symptoms include joint pain, but also fevers and skin rashes. Here is the latest on this disease.

Chromatin Regulation and Circadian Clocks

The circadian clock plays an important role in regulating transcriptional dynamics through changes in chromatin folding and remodelling. Discover the latest research on Chromatin Regulation and Circadian Clocks here.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain. Disocver the latest research on single cell analysis of the gut-brain axis here.
