INDICATIONS The Absorb GT1 Bioresorbable Vascular Scaffold (BVS) is a temporary scaffold that will fully resorb over time and is indicated for improving coronary luminal diameter in patients with ischemic heart disease due to de novo native coronary artery lesions (length ≤ 24 mm) with a reference vessel diameter of ≥ 2.5 mm and ≤ 3.75 mm WHAT ARE THE POTENTIAL RISKS AND COMPLICATIONS? Treatment options for CAD have become increasingly common but, as with any invasive procedure, there are potential risk factors and complications. Serious complications do not occur often, and research is ongoing to make these procedures even safer and more effective. The risk of complications from percutaneous treatment methods may be higher for individuals: 75 years of age and older Who are women Who have kidney disease or diabetes Who have serious heart disease Who have had prior cardiac interventions

Newborn Jaundice
Newborn Jaundice samer kareem 2,553 Views • 2 years ago

Infant jaundice is a yellow discoloration in a newborn baby's skin and eyes. Infant jaundice occurs because the baby's blood contains an excess of bilirubin (bil-ih-ROO-bin), a yellow-colored pigment of red blood cells. Infant jaundice is a common condition, particularly in babies born before 38 weeks gestation (preterm babies) and some breast-fed babies. Infant jaundice usually occurs because a baby's liver isn't mature enough to get rid of bilirubin in the bloodstream. In some cases, an underlying disease may cause jaundice. Treatment of infant jaundice often isn't necessary, and most cases that need treatment respond well to noninvasive therapy. Although complications are rare, a high bilirubin level associated with severe infant jaundice or inadequately treated jaundice may cause brain damage.

A bulla is a fluid-filled sac or lesion that appears when fluid is trapped under a thin layer of your skin. It’s a type of blister. Bullae (pronounced as “bully”) is the plural word for bulla. To be classified as a bulla, the blister must be larger than 0.5 centimeters (5 millimeters) in diameter. Smaller blisters are called vesicles.

From axons to tracts
From axons to tracts Mohamed 21,086 Views • 2 years ago

The complex circuitry interconnecting different areas in the brain, known collectively as white matter, is composed of millions of axons organized into fascicles and bundles. Upon macroscopic examination of sections of the brain, it is difficult to discern the orientation of the fibers. The same is true for conventional imaging modalities. However, recent advancements in magnetic resonance imaging (MRI) make such task possible in a live subject. By sensitizing an otherwise typical MRI sequence to the diffusion of water molecules it is possible to measure their diffusion coefficient in a given direction1. Normally, the axonal membrane and myelin sheaths pose barriers to the movement of water molecules and, thus, they diffuse preferentially along the axon2. Therefore, the direction of white matter bundles can be elucidated by determining the principal diffusivity of water. The three-dimensional representation of the diffusion coefficient can be given by a tensor and its mathematical decomposition provides the direction of the tracts3; this MRI technique is known as diffusion tensor imaging (DTI). By connecting the information acquired with DTI, three-dimensional depictions of white matter fascicles are obtained4. The virtual dissection of white matter bundles is rapidly becoming a valuable tool in clinical research.

Our journey begins with a transverse section of tightly packed axons as seen through light microscopy. Although represented as a two-dimensional "slice", we see that these axons in fact resemble tubes. A simulation of water molecules diffusing randomly inside the axons demonstrates how the membranes and myelin hinder their movement across them and shows the preferred diffusion direction --along the axons. The tracts depicted through DTI slowly blend in and we ride along with them. As we zoom out even more, we realize that it is a portion of the corpus callosum connecting the two sides of the brain we were traveling on and the great difference in relative scale of the individual axons becomes evident. The surface of the brain is then shown, as well as the rest of the white matter bundles--a big, apparently chaotic tangle of wires. Finally, the skin covers the brain.

With the exception of the simulated water molecules, all the data presented in the animation is obtained through microscopy and MRI. Computer algorithms for the extraction of the cerebral structures and a custom-built graphics engine make our journey through the brain's anatomy possible in a living person.

How osteoporosis develops
How osteoporosis develops samer kareem 13,076 Views • 2 years ago

Osteoporosis is a disease in which bones become brittle and fragile due to low bone mass and bone tissue loss. It's the most common type of bone disease, according to the National Institutes of Health (NIH), and increases your risk of fractures, particularly of the hips, spine, and wrists. Prevalence In the United States, nearly 54 million people ages 50 and older were living with osteoporosis or osteopenia (low bone mass ) in 2010, according to a 2014 article in the Journal of Bone and Mineral Research. More specifically, 10.2 million adults had osteoporosis, and 43.4 million adults had osteopenia, which puts a person at high risk for osteoporosis.

Then you might want to start transitioning over to a low fat high fiber diet. Aside from this, you’ll also want to concentrate on foods that contain biotins, which play an essential role in maintaining healthy hair. Fish, cooked eggs, whole milk, and various nuts and fruits – all of these are good sources of biotins so it’s best that you take note of them. Drink plenty of water: It’s not only that gets thirsty, as even your hair requires the moisture that water provides. Dehydration can lead to symptoms like constipation, eczema, thick dandruff, wrinkly skin, foul breath and hair loss. Remember that your body is made up of 98% water and you need to maintain it at optimum levels if you want to keep your hair in place. An easy way to quickly replenish and establish enough water in your body is to routinely drink at least 8 ounces of water immediately after you urinate.

Cartilage is a slippery tissue that provides a smooth surface for joint motion and acts as a cushion between the bones. Synovium is soft, and it lines the joints. It produces fluid, called synovial fluid, for lubrication, and it supplies nutrients and oxygen to the cartilage. As these functions break down, they no longer protect the bones of the knee joint, and bone damage occurs. OA of the knee can cause pain and stiffness. The symptoms worsen over time
