Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

66.0K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Perpendicular-Axis Theorem01:16

Perpendicular-Axis Theorem

4.6K
The perpendicular-axis theorem states that the moment of inertia of a planar object about an axis perpendicular to its plane is equal to the sum of the moments of inertia about two mutually perpendicular concurrent axes lying in the plane of the body.
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...

Parallel-axis Theorem01:06

Parallel-axis Theorem

8.3K
The parallel-axis theorem provides a convenient and quick method of finding the moment of inertia of an object about an axis parallel to the axis passing through its center of mass. Consider a thin rod as an example. There is a striking similarity between the process of finding the moment of inertia of a thin rod about an axis through its middle, where the center of mass lies, and about an axis through its end using the conventional method. In the conventional method, the concept of linear mass...

Load along a Single Axis

646
In structural engineering, the analysis of beams subjected to varying loads is a critical aspect of understanding the behavior and performance of these structural elements. A common scenario involves a beam subjected to a combination of different load distributions.
Consider a beam of length L subjected to a varying load, which is a combination of parabolic and trapezoidal load distribution along the x-axis. In this case, it is essential to determine the resultant loads, their locations, and...

Parallel-Axis Theorem for an Area01:12

Parallel-Axis Theorem for an Area

3.0K
The moment of inertia is a fundamental concept in mechanical engineering that plays a significant role in designing rotationally symmetric objects such as flywheels, gears, and other mechanical systems. In this context, we will discuss the moment of inertia of a flywheel rotating about its centroidal axis and how it relates to the moment of inertia about an axis parallel to it.
For a flywheel approximated as a solid disc, consider an infinitesimal differential element with an arbitrary distance...

Moment of a Force About an Axis: Scalar01:28

Moment of a Force About an Axis: Scalar

702
The moment of a force about an axis is a crucial concept in mechanics that helps determine an object's rotational motion around a specific point or axis. The moment of force can be calculated using scalar analysis, which involves considering the perpendicular distance between the axis of rotation and the line of action of the force or simply the moment arm.
To better understand the concept of moment of force, consider the example of a cyclist riding a bicycle. When the cyclist applies force on...

Summary

Neuroimmune interactions offer a new therapeutic target for acute kidney injury (AKI). Stimulating the vagus nerve or using pulsed ultrasound can prevent AKI by activating the cholinergic anti-inflammatory pathway.

Area of Science:

  • Neuroscience
  • Immunology
  • Nephrology

Background:

  • Neuroimmune interaction, the bidirectional communication between the nervous and immune systems, is a rapidly developing field.
  • This interaction is increasingly recognized for its role in inflammatory diseases, particularly acute kidney injury (AKI).

Purpose of the Study:

  • To review the role of neural circuits in controlling renal inflammation and AKI.
  • To explore the potential of neuroimmune modulation as a therapeutic strategy for AKI.
  • To highlight optogenetics as a tool for studying these neural circuits.

Main Methods:

  • Review of existing literature on neuroimmune interactions in AKI.
  • Discussion of the cholinergic anti-inflammatory pathway.
  • Introduction to optogenetics for neural circuit investigation.

Main Results:

  • Vagus nerve stimulation and pulsed ultrasound activate the cholinergic anti-inflammatory pathway, demonstrating a neuroprotective effect against AKI in mouse models.
  • Renal innervation by sympathetic and sensory neurons suggests their involvement in modulating inflammation during AKI.

Conclusions:

  • The nervous system, through pathways like the cholinergic anti-inflammatory pathway, plays a significant role in regulating renal inflammation and AKI.
  • Targeting neuroimmune interactions presents a promising therapeutic avenue for managing AKI.
  • Optogenetics offers a powerful method for dissecting the complex neural circuits involved in renal inflammation.
