Application and direct measurements of forces on neurons in the 2-1000 microdyne range are achieved with high precision using calibrated glass needles. This methodology can be used to control and measure several aspects of axonal development, including axonal initiation, axonal tension, velocity of axonal elongation, and force vectors.

2014
Pneumonia is one of the top ten leading causes of death in the U.S. Osteopathic manipulative techniques (OMT) may be utilized as an adjunctive therapy in the treatment of pneumonia to enhance biomechanical and immune function; and ultimately, to reduce hospital stay, duration of antibiotics, incidence of respiratory failure, and mortality. In this video-article, we will review randomized controlled studies on the use of OMT in pneumonia patients, as well as demonstrate specific hands-on...

We present two independent, microscope-based tools to measure the induced nuclear and cytoskeletal deformations in single, living adherent cells in response to global or localized strain application. These techniques are used to determine nuclear stiffness (i.e., deformability) and to probe intracellular force transmission between the nucleus and the cytoskeleton.

This protocol designs a cannula that can be used to control the range of motion for the lifting and thrusting manipulation in acupuncture, thereby improving stability and safety. It can thus serve both the clinical application and scientific research of acupuncture treatment.
FAQs
These variables determine how biological material responds during handling. Greater or sustained force can promote movement, deformation, separation, or assembly, while viscosity changes how readily material flows or resists motion. Pressure and exposure time also influence the result. Controlling these conditions helps researchers obtain consistent sample preparation and distinguish intended physical effects from unwanted changes.
Biological materials can respond differently depending on the physical conditions applied. Inconsistent force, pressure, or handling duration may alter how a sample moves, separates, or interacts with other components. Careful control improves experimental accuracy and makes physical responses easier to interpret, particularly when researchers are examining how cellular or molecular structures respond to stress.
Researchers can observe how biological structures respond when the applied conditions are varied. Changes in force, pressure, viscosity, or exposure time may reveal whether material moves, deforms, separates, or remains stable. This connects biochemical function with physical behavior and helps characterize the properties of biomolecules, cellular components, or other biological materials under controlled manipulation.
Common approaches include pipetting, mixing, centrifugation, microfluidic flow, and micromanipulation. Each provides a way to deliver or control physical forces during an experiment. Researchers select among them according to whether they need to prepare a sample, move material, isolate biomolecules or cellular components, control molecular interactions, or examine responses to mechanical stress.
Physical handling processes can prepare biological samples before analysis and help separate biomolecules or cellular components. Pipetting and mixing support controlled sample handling, while centrifugation and microfluidic flow provide additional ways to direct material through an experimental workflow. The resulting preparation can improve access to biochemical components and support more accurate downstream observations.
It is useful when an experiment requires precise handling of biological material or an assessment of physical response. Applications include sample preparation, isolation of biomolecules or cellular components, control of molecular interactions, and study of responses to mechanical stress. These uses make the approach relevant for linking biochemical activity with the physical behavior of matter.
