Adenocarcinoma of the Transverse Colon taken by Dr. Julio Murra Saca This is the case of a 42 year-old male, with no significant past medical history presented with abdominal pain and no weight loss was reported. Adenocarcinoma of the colon is a primary cause of mortality and
morbidity in North America and Western Europe. Colonic cancers are the most common GI carcinomas and have the best prognosis. The 5-year survival rate is approximately 50%.
Survival rates may be improved by screening and removal of adenomatous polyps. Almost all colonic cancers are primary adenocarcinomas.

Intra Oral Camera
Intra Oral Camera Mohamed 12,997 Views • 3 years ago

Walk through your mouth with Intra Oral Technology and see the unseen! Most of us can't really see what is going on in our mouths because it is a very small, and shadowed area. What we don't know is that many situations and conditions in the mouth and painless and not always visible to the naked eye.

The Intra Oral Camera is a fascinating innovation in dentistry that allows the client and our clinicians to look deep into the mouth and observe the teeth at a very close angle. This wand like camera which transfers images to a television, can see so close to a tooth that it can see mini fractures, chips, secondary decay, wear down of the teeth, damaged and broken fillings and crowns and even gum disease. At Yaletown we believe that people can decide what is best for their own health. The Intra Oral Camera is a wonderful educational tool for clients so they can learn about their mouths to help them on their journey to overall dental wellness.

From axons to tracts
From axons to tracts Mohamed 21,097 Views • 3 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.
