Insights

Serum substance P (SP) levels are higher and vasoactive intestinal peptide (VIP) levels are lower in infants with acute intussusception. These levels normalize with treatment, suggesting a role in the condition's development.

Area of Science:

  • Pediatric Gastroenterology
  • Neurogastroenterology
  • Intestinal Physiology

Background:

  • Intussusception is a common cause of intestinal obstruction in infants.
  • Intestinal neurotransmitters like substance P (SP) and vasoactive intestinal peptide (VIP) play roles in gut motility and function.
  • The specific involvement of SP and VIP in the pathogenesis of infant intussusception requires further elucidation.

Purpose of the Study:

  • To investigate the role of intestinal neurotransmitters, specifically vasoactive intestinal peptide (VIP) and substance P (SP), in infants diagnosed with acute intussusception.
  • To compare serum levels of SP and VIP at various time points (pre- and post-operation) between infants with intussusception and a control group.

Main Methods:

  • A comparative study involving 30 infants with acute intussusception (experimental group) and 30 infants with indirect inguinal hernia (control group).
  • Serum samples were collected pre- and post-operation.
  • Enzyme-linked immunosorbent assay (ELISA) was used to quantify serum levels of SP and VIP.
  • Statistical comparison of neurotransmitter levels between the groups and over time.

Main Results:

  • Serum SP levels were significantly elevated in infants with acute intussusception compared to controls.
  • Following treatment and recovery from intussusception, SP levels demonstrated a gradual decrease.
  • Serum VIP levels were significantly reduced in infants with acute intussusception compared to controls.
  • VIP levels showed a gradual increase post-treatment, correlating with recovery.

Conclusions:

  • The findings suggest a potential association between altered serum levels of SP and VIP and the pathogenetic mechanisms underlying acute intussusception in infants.
  • SP and VIP may serve as potential biomarkers for intussusception and its recovery process.

Peptide Bonds02:43

Peptide Bonds

A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Deleterious Substances in Aggregate

Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Connective Tissue Fibers and Ground Substance

One of the significant functions of connective tissue is connecting tissues and organs. Unlike epithelial tissue that is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. It plays a significant role in the functioning of this tissue. The major component of the matrix is a...

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...
