In pressure myography, an intact small segment of a vessel is mounted onto two small cannulas and pressurized to a suitable luminal pressure. Here, we describe the method to measure vasorelaxation response of the mouse 3rd order mesenteric arteries in c57 and sGCα1-/- mice using pressure myography.

Pressure myography is used to assess vasoactivity of small arteries that develop sustained constriction when pressurized. This manuscript provides a detailed protocol to assess in isolated segments of small mesenteric arteries from rats, vasoactivity and the effect of intraluminal pressure on vascular diameter.

The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Source: Alexander S Rattner, Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA This experiment introduces the measurement and modeling of pressure losses in piping networks and internal flow systems. In such systems, frictional flow resistance from channel walls, fittings, and obstructions causes mechanical energy in the form of fluid pressure to be converted to heat. Engineering analyses are needed to size flow hardware to ensure...
FAQs
An Air Pressure Resistant Door handles pressure differences through three coordinated features: reinforced construction resists deformation, fitted seals reduce gaps, and the latching mechanism keeps the door firmly closed. Together, these elements limit uncontrolled leakage so the intended airflow relationship between adjoining rooms remains more stable. This mechanical reliability is essential when ventilation depends on directional pressure control.
Negative-pressure isolation rooms are used to contain infectious aerosols, while positive-pressure protective environments are used to keep contaminants out. An Air Pressure Resistant Door must support either arrangement by limiting unintended exchange when closed. The pressure direction therefore determines the infection-control objective: containment protects surrounding areas, whereas protection preserves a cleaner room environment.
When seals do not fit tightly or the latching mechanism does not secure the door, gaps can permit uncontrolled leakage despite the ventilation system's intended pressure relationship. That weakness may reduce containment in an isolation room or allow contaminants to enter a protective environment. Seal fit and latch security therefore connect the door's mechanical performance directly to infection-control effectiveness.
The essential operating sequence is to keep the door closed and securely latched whenever the pressure-controlled room is in use, allowing the fitted seals to limit leakage. Its performance should be considered alongside the room's ventilation arrangement, because the barrier supports rather than replaces pressure control. This coordinated use helps maintain the intended separation between adjacent spaces.
They are relevant wherever rooms must remain separated by controlled pressure conditions, including infectious-disease isolation spaces and protective environments. In clinical care and infection research, they support ventilation strategies designed either to contain infectious aerosols or to exclude contaminants. Their value is greatest as part of a coordinated room and facility design for airborne-transmission control.
By reducing uncontrolled leakage at a pressure boundary, reliable operation helps the ventilation system maintain the separation it was designed to provide. That contribution can protect patients and healthcare workers, support containment procedures, and strengthen defenses against airborne transmission. The door is therefore one engineered element within a broader infection-control system, not a substitute for the ventilation arrangement itself.
