Light Acquisition02:16

Light Acquisition

8.0K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

6.0K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.7K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Veins of Lower Limbs01:15

Veins of Lower Limbs

3.1K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Modeling and Similitude

811
Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...

Veins of Thorax01:19

Veins of Thorax

2.6K
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

Summary

The SAPIEN 3™ (S3) transcatheter aortic valve implantation device shows promise in reducing vascular complications and paravalvular leaks. However, it may increase the risk of atrioventricular block requiring a permanent pacemaker.

Area of Science:

  • Cardiovascular Medicine
  • Medical Devices
  • Interventional Cardiology

Background:

  • Transcatheter aortic valve implantation (TAVI) is a key treatment for severe aortic stenosis in high-risk patients.
  • Future TAVI devices aim for improved safety and efficacy to expand patient eligibility.
  • Ideal prostheses require durability, optimal hemodynamics, and reduced complications like vascular injury, paravalvular leaks, stroke, and atrioventricular block.

Purpose of the Study:

  • To evaluate the safety and efficacy of the SAPIEN 3™ (S3) transcatheter heart valve.
  • To compare the S3 valve's performance against previous Edwards valve models.
  • To assess the S3 valve's impact on major TAVI complications.

Main Methods:

  • Analysis of data from the SAPIEN3 trial presented at EuroPCR 2014.
  • Comparison of S3 valve outcomes with SAPIEN and SAPIEN XT valves.
  • Assessment of vascular complications, paravalvular leaks, and pacemaker implantation rates.

Main Results:

  • The S3 valve demonstrated reduced vascular complications compared to earlier models.
  • Moderate-to-severe paravalvular leaks were less frequent with the S3 valve.
  • An increased incidence of atrioventricular block requiring permanent pacemaker implantation was observed with the S3 valve.

Conclusions:

  • The SAPIEN 3™ valve represents a significant advancement in TAVI technology.
  • It effectively lowers risks of vascular complications and paravalvular regurgitation.
  • Further investigation is needed regarding the increased risk of atrioventricular block, potentially linked to implantation depth.
