Magnetic Field due to Moving Charges01:23

Magnetic Field due to Moving Charges

11.6K
A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...

Conservation of Mass in Moving, Nondeforming Control Volume

1.3K
Stormwater detention basins are essential in managing runoff during heavy rainfall, particularly in urban areas where impervious surfaces increase the risk of flooding. Understanding the conservation of mass in these systems allows engineers to optimize basin performance, balancing inflow, outflow, and water storage.
In the context of a detention basin, the conservation of mass states that the total mass of water entering the basin must equal the mass leaving the basin plus any accumulation of...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.9K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Targets for Drug Action: Overview01:26

Targets for Drug Action: Overview

10.3K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

5.7K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Nuclear Transmutation03:20

Nuclear Transmutation

20.7K
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed...

Summary
This summary is machine-generated.

Relapsing intestinal dysmotility arises from partial enteric nervous system (ENS) loss due to viruses, leading to inflammation-induced functional decline. This study identifies a key mechanism behind recurring gut motility disorders.

Area of Science:

  • Gastroenterology
  • Neuroscience
  • Immunology

Background:

  • The enteric nervous system (ENS) regulates intestinal motility.
  • Dysmotility diseases represent a spectrum of disorders affecting gut function.
  • The ENS is a potential therapeutic target for these conditions.

Purpose of the Study:

  • To investigate the mechanisms underlying relapsing intestinal dysmotility.
  • To explore the role of enteric neurotropic viruses and inflammation in ENS dysfunction.

Main Methods:

  • The study by White et al. examined the impact of partial ENS depletion.
  • Investigated the consequences of enteric neurotropic viral infection.
  • Assessed functional impairment resulting from intermittent intestinal inflammation.

Main Results:

  • Partial depletion of the ENS by enteric neurotropic viruses was identified as a key factor.
  • Subsequent intermittent, nonspecific intestinal inflammation leads to functional impairment.
  • This sequence of events results in relapsing intestinal dysmotility.

Conclusions:

  • Relapsing intestinal dysmotility is mechanistically linked to viral-induced ENS damage followed by inflammatory episodes.
  • Understanding this pathway offers insights into treating recurrent gut motility disorders.
