Tension01:10

Tension

13.9K
Tension is a force along the length of a medium, in particular, a force carried by a flexible medium, such as a rope or cable. The word "tension" comes from Latin, meaning "to stretch". Not coincidentally, the flexible cords that carry muscle forces to other parts of the body are called tendons. Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pull only parallel to its length; so, a force carried by a flexible connector is a tension with a...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Surface Tension of Fluid

1.6K
Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.

Tension Response at Adherens Junctions

3.6K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
α-Catenin as a Mechanosensory Protein
The α-catenin of adherens junctions is an allosteric protein with three VH (vinculin...

Surface Tension and Surface Energy01:16

Surface Tension and Surface Energy

3.3K
When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Types of RNA01:23

Types of RNA

72.9K
Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

Summary

Tension-type headache (TTH) is a common disorder causing significant disability. Management includes acute nonprescription analgesics for episodic cases and prophylaxis with amitriptyline or physical therapies for chronic TTH.

Area of Science:

  • Neurology
  • Primary Headache Disorders

Background:

  • Tension-type headache (TTH) is the most prevalent primary headache disorder globally.
  • TTH leads to substantial disability and lost workdays, exceeding that of migraine.
  • Its etiology is multifactorial, influenced by genetic and environmental elements.

Purpose of the Study:

  • To outline the management strategies for Tension-type Headache (TTH).
  • To discuss pharmacological and non-pharmacological treatment options for TTH.
  • To highlight prophylaxis indications and first-line treatments for chronic TTH.

Main Methods:

  • Review of current literature on TTH diagnosis and management.
  • Identification of recommended treatments for episodic and chronic TTH subtypes.
  • Exploration of pharmacological (amitriptyline) and integrative therapies.

Main Results:

  • Episodic TTH is managed with nonprescription analgesics.
  • Prophylaxis is recommended for chronic, frequent episodic TTH, and at-risk patients.
  • Amitriptyline is a first-line prophylactic option (off-label use).

Conclusions:

  • Effective management of TTH involves tailored approaches based on headache frequency and chronicity.
  • Integrative therapies such as biofeedback, CBT, exercise, and massage offer complementary treatment options.
  • Pharmacological prophylaxis, including amitriptyline, plays a crucial role in managing refractory TTH.
