Perforative Lift Surgery

Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

The video demonstrates the induction of subarachnoid hemorrhage via endovascular perforation in a mouse model. An incision is made in the neck region of the anesthetized mouse to access the common carotid artery and its bifurcation. A filament is inserted through the arteries to perforate an intracranial artery branch, inducing subarachnoid hemorrhage.

This video demonstrates electrophysiological recording of olfactory sensory neurons (OSNs) in mice using a perforated patch-clamp technique. The olfactory epithelium, containing OSNs with fluorophore-tagged odor receptors, is isolated from a mouse and secured in a recording chamber. A recording pipette is clamped to the dendritic knob of an OSN, and nystatin within the pipette perforates the membrane to form electrical connectivity with the cell. Finally, another pipette is used to deliver an...

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks. The location of esophageal perforation can vary, occurring anywhere along the esophagus.

Wing performance can be further enhanced by deploying high-lift devices, such as flaps (at the trailing edge) and slats (at the leading edge) during takeoff or landing. In this experiment, a wind tunnel is utilized to generate certain airspeeds, and a Clark Y-14 wing with a flap and slat...
