Transverse aortic constriction (TAC) in the mouse is a commonly used experimental model to study mechanisms underlying cardiac hypertrophy and heart failure development. Here, we describe procedures to constrict the aorta to create a reproducible degree of cardiac hypertrophy in mice.

Hypothalamic-Pituitary Axis

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. What Happens During Stress In response to stress, the neurons in the hypothalamus release...

Minimally invasive transverse aortic constriction (MTAC) conserves the essentials of regular transverse aortic constriction (TAC) while eliminating the use of a ventilator with tracheal intubation. It proves to be a highly desirable method for high-throughput studies on left ventricular overload, particularly in translational studies.

Speed of a Transverse Wave

The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length. One of the key properties of any wave is the wave speed. Light...

The present protocol describes a modified and simplified technique with a minimally invasive transverse aortic constriction (TAC) procedure using a self-made retractor. This procedure can be conducted without a ventilator or microscope and introduces pressure overload, eventually leading to cardiac hypertrophy or heart failure.
FAQs
The squared coordinate with the positive term identifies the opening direction in the standard form shown. In x²/a² − y²/b² = 1, the positive x-term places the transverse axis horizontally; exchanging the roles of x and y gives the vertical counterpart. This comparison helps distinguish the two orientations before graphing.
The parameter a controls the vertices rather than merely scaling the drawing. Each vertex lies a distance a from the center along the transverse axis, so increasing a moves the vertices farther apart and changes the full vertex-to-vertex length to 2a. Reading a correctly is therefore essential when plotting the central portion of the hyperbola.
The axis provides a geometric reference for several later constructions. Once its direction and vertex spacing are known, a graph can be oriented correctly, the foci can be located relative to that orientation, and asymptotes can be derived from the corresponding conic structure. Thus, identifying it connects the equation with both visible and calculated features.
Start by matching the equation to its orientation: in x²/a² − y²/b² = 1, the x-term is positive, so use the x-axis as the transverse direction. Then use the center and the value of a to mark vertices at equal distances on that line. This sequence establishes the structure needed for a reliable sketch.
During graphing, the transverse axis acts as the first geometric guide rather than a final measurement only. Marking the center, placing the two vertices a units away, and extending the branches in the indicated horizontal or vertical direction gives the sketch its correct orientation. The same reference also helps organize asymptote derivation.
In coordinate geometry, the transverse axis links algebraic parameters to conic features: a determines vertex spacing, while the axis indicates the relevant direction for foci and asymptotes. In applied mathematical modeling, this relationship helps interpret whether a modeled hyperbolic pattern extends horizontally or vertically, making the equation’s geometry easier to read.
