Insights

Early recombinant human erythropoietin (rhEPO) administration improves white matter development in preterm infants. This neuroprotective effect was observed using diffusion tensor imaging (DTI) and fractional anisotropy (FA) measurements.

Area of Science:

  • Neonatal neurology
  • Neurodevelopmental imaging
  • Pharmacological interventions

Background:

  • Preterm infants face risks of white matter damage.
  • Early interventions are crucial for neuroprotection.

Purpose of the Study:

  • To assess the impact of early recombinant human erythropoietin (rhEPO) on white matter development in preterm infants.
  • Utilized fractional anisotropy (FA) from diffusion tensor imaging (DTI) to quantify white matter integrity.

Main Methods:

  • 81 preterm infants (gestational age ≤32 weeks) were randomized into rhEPO and control groups.
  • rhEPO or saline was administered within 24 hours of birth.
  • Head MRI, DTI, and FA calculations were performed at 35-37 weeks corrected gestational age.

Main Results:

  • No significant differences in intracranial hemorrhage or white matter damage incidence between groups.
  • The rhEPO group showed higher FA values in specific white matter tracts (internal capsule, corpus callosum, frontal, and occipital white matter).
  • No significant FA differences were found in parietal white matter or deep gray matter nuclei.

Conclusions:

  • Early rhEPO application demonstrates a neuroprotective effect on white matter development in preterm infants.
  • rhEPO may promote white matter maturation and integrity.

Classifying Matter by State

Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

The Atomic Theory of Matter

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...

What is Matter?

The substance of the universe—from a grain of sand to a star—is called matter. Scientists define matter as anything that occupies space and has mass. An object’s mass and its weight are related concepts, but not quite the same. An object’s mass is the amount of matter contained in the object and is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object’s weight, on the other hand, is its mass as affected by the pull of...

States of Matter

Solids, liquids, and gases are the three states of matter commonly found on Earth. A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of its container, except it forms a flat or slightly curved upper surface when acted upon by gravity. Both liquid and solid samples have volumes nearly independent of pressure. A gas takes both the shape and volume of its container.
Scientists have discovered a fourth state of matter, plasma, that occurs naturally in the interiors...
