Abstract

Excessively crying, hard-to-soothe infants are described as colicky. The self-limiting course of infantile colic during early infancy suggests an etiology of transient developmental dysmaturation. It has been proposed that emotional characteristics such as temperament and self-soothing ability are correlated with the balance of the autonomic nervous system. Heart rate variability (HRV) analysis was used for evaluating the balance of the autonomic nervous system in colicky and control infants during and after the colicky period. HRV analysis was carried out on 12 colicky infants and 14 control infants at the age of 2 mo, and repeated on 10 colicky and 11 normal infants at the age of 7 mo. Measurements were performed during polygraphically confirmed slow-wave sleep (sleep stages 3 and 4). Three HRV frequency bands were defined, including a high (0.2-1.0 Hz), middle (0.12-0.2 Hz) and low (0.025-0.12 Hz) frequency variability. There were no differences between the study groups in any of the three HRV frequency bands analyzed. The high frequency variability increased significantly with age in both study groups (p = 0.009). The findings suggest that imbalance between the parasympathetic and the sympathetic nervous system is not assoc...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.
