Hypertension, a major cardiovascular disease, is one of the most prevalent and death causing disease worldwide. In the US, over 70 million adults have high blood pressure, that is, 1 in 3. A prolonged state of hypertension cause damages to the brain cells, the kidneys and can lead to a stroke. This research studies the biomechanical response of amphibian hearts in vivo when in hypertensive. A normotensive state is used as the control. Hypertension is induced by injecting a saline fluid directly into the heart ventricle using a syringe. The response of the heart is characterized by monitoring surface deformation …

It is well known that Atomic Force Microscopy imaging is capable of yielding high resolution results with of surfaces at the nanoscale. However, despite the device capabilities and vast applications, AFM microscopy is possibly the most prone to the creation of image artifacts. AFM imaging can easily, and is often, corrupted by various external forces. The most obvious and measurable form of external interference is of course the presence of ambient noise. Most AFM manufactures attempt to counter the effects of such noise on the imaging process through use of noise-proof or noise-resistant shields that cover the microscope aperture. Without …
