Pleiotropy01:33

Pleiotropy

40.6K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Neurulation01:30

Neurulation

42.0K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

2.6K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Glucose Transporters01:27

Glucose Transporters

22.8K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

959
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Area of Science:

  • Gastroenterology
  • Pediatric Surgery
  • Genetics

Background:

  • Hirschsprung disease (HSCR) is a congenital intestinal disorder affecting 1 in 5,000 live births.
  • Characterized by the absence of nerve cells (ganglion cells) in the intestinal wall, leading to functional obstruction.
  • Often presents neonatally with delayed meconium passage, abdominal distension, and vomiting.

Purpose of the Study:

  • To provide a comprehensive overview of Hirschsprung disease.
  • To detail current diagnostic and surgical management strategies.
  • To highlight associated syndromes, genetic factors, and future research directions.

Main Methods:

  • Diagnosis relies on contrast enema to identify the transition zone and rectal biopsy for confirmation.
  • Surgical management involves removing the aganglionic segment and reconnecting healthy bowel to the anus.
  • Surgical approaches include Swenson, Soave, and Duhamel procedures, with options for laparoscopic assistance.

Main Results:

  • HSCR is associated with syndromes like trisomy 21 and involves genes such as RET and EDNRB.
  • Surgical success aims to restore bowel continuity and preserve sphincter function.
  • Potential comorbidities include obstructive symptoms, enterocolitis, and soiling.

Conclusions:

  • Continued research into HSCR mechanisms is crucial for advancing diagnostic and therapeutic innovations.
  • Improving understanding of HSCR pathogenesis will enhance patient outcomes.
  • Multidisciplinary approaches are essential for managing this complex congenital condition.
