Summary
This study analyzed plasma proteome changes in preterm infants, revealing how gestational age impacts systemic homeostasis and recovery pathways. Key findings include gestational age-dependent hemopexin induction and altered inflammatory and coagulation factors.
Area of Science:
- Neonatal research
- Proteomics
- Systems biology
Background:
- Preterm birth leads to systemic immaturity and developmental challenges.
- Understanding plasma proteome changes is crucial for neonatal care.
- Gestational age significantly influences infant development and recovery.
Purpose of the Study:
- To analyze time-resolved plasma proteome changes in preterm neonates.
- To identify malfunctioning pathways due to systemic immaturity.
- To highlight differentially regulated pathways during early development.
Main Methods:
- Quantitative proteomics was used to assess plasma protein abundances.
- Preterm neonates were stratified into three gestational age groups.
- Plasma samples were collected at delivery and 36 weeks post-menstrual age.
Main Results:
- Significant time-related differences in plasma protein abundances were observed.
- Key changes were noted in inflammatory, immunomodulatory, and coagulation pathways.
- Hemopexin induction showed a strong gestational age dependency.
Conclusions:
- Gestation duration profoundly impacts systemic homeostasis recovery post-preterm birth.
- The data suggests a progression toward recovery from perinatal perturbations.
- Proteomic analysis provides insights into preterm infant development and resilience.

01:22Diabetes Mellitus: Type 2 and Gestational
5.0K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

9.8K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:29Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

01:19The Effect of Aging on Tissues
3.6K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
