Insights

Intrauterine growth retardation (IUGR) in neonates is linked to reduced insulin sensitivity and lower adiponectin levels. These findings suggest a potential connection between adiponectin and insulin resistance in newborns with IUGR.

Area of Science:

  • Neonatal Endocrinology
  • Metabolic Disorders
  • Perinatal Medicine

Background:

  • Intrauterine growth retardation (IUGR) is a significant concern in neonatology.
  • Insulin sensitivity plays a crucial role in neonatal metabolic health.
  • Adiponectin, a key adipokine, influences glucose and lipid metabolism.

Purpose of the Study:

  • To investigate the impact of IUGR on neonatal insulin sensitivity.
  • To examine the relationship between insulin sensitivity and plasma adiponectin levels in neonates.

Main Methods:

  • Comparison of term neonates with IUGR (n=82) and appropriate for gestational age (AGA) neonates (n=90).
  • Measurement of anthropometric data, glucose, lipids, insulin, and adiponectin levels on day 7 postpartum.
  • Calculation of Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) and Insulin Sensitivity Index (ISI).

Main Results:

  • No significant differences in glucose or lipid profiles between IUGR and AGA groups.
  • IUGR neonates exhibited higher plasma insulin and lower plasma adiponectin levels (P<0.05).
  • IUGR group showed increased HOMA-IR and decreased ISI (P<0.05), with HOMA-IR negatively correlated with adiponectin and birth weight.

Conclusions:

  • Neonates with IUGR demonstrate impaired insulin sensitivity and elevated insulin levels.
  • Reduced plasma adiponectin levels in IUGR neonates may be associated with their decreased insulin sensitivity.

Retarders

Retarders are chemical admixtures designed to extend the setting time, which is especially useful when there is a delay in sequential concrete pours to prevent cold joints and to achieve a cohesive structure. Retarders, when used in appropriate amounts, can also enhance the architectural appearance of exposed aggregate finishes.
The function of retarders is to delay the setting of concrete, and this effect can be measured using a penetration test. The retardation process involves adding...

Factors Affecting Renal Clearance: Drug's Physicochemical Properties and Plasma Levels

Renal clearance of a drug is influenced by various factors, including its physicochemical properties and plasma levels. These factors play a significant role in determining how efficiently the kidneys eliminate a drug.
One important factor is the drug's molecular size. The kidneys readily excrete smaller molecules below 300 Daltons (Da). On the other hand, molecules weighing between 300 and 500 Da are excreted through both urine and bile. Larger molecules above 500 Da tend to be excreted...

Insulin Secretory Vesicles01:05

Insulin Secretory Vesicles

Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

Leveling Effect01:29

Leveling Effect

In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Insulin: The Receptor and Signaling Pathways01:28

Insulin: The Receptor and Signaling Pathways

Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

Insulin Formulations: Types and Delivery

Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into...
