RDSRespiratory distress syndrome, a problem often seen in premature babies. The condition makes it hard for the baby to breathe. Neonatal RDS occurs in infants whose lungs have not yet fully developed. The disease is mainly caused by a lack of a slippery substance in the lungs called surfactant. This substance helps the lungs fill with air and keeps the air sacs from deflating. Surfactant is present when the lungs are fully developed. Neonatal RDS can also be due to genetic problems with lung development. Most cases of RDS occur in babies born before 37 weeks. The less the lungs are developed, the higher the chance of RDS after birth. The problem is uncommon in babies born full-term (at 40 weeks). Source: Medline Plus |
REEResting Energy Expenditure, the amount of energy, usually expressed in kcal (food calories), required for a 24-hour period by the body during resting conditions. It is closely related to, but not identical to, basal metabolic rate. Source: Wikipedia |
RNARibonucleic acid, a polymeric molecule implicated in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the three major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded unto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the letters G, U, A, and C to denote the nitrogenous bases guanine, adenine, uracil and cytosine) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome. Source: Wikipedia |
