If you are tired of dealing with glasses or squinting to read signs in the distance, then you should consider LASIK Eye Surgery. In this outpatient refractive procedure, lasers are used to correct vision issues by changing the structure of the cornea. This may entirely eliminate reliance upon glasses or contacts. In this interactive LASIK Eye Surgery, you will assist in numbing the patient’s eye and cleaning the area for the procedure. With a speculum, you will hold the eye open, mark the cornea using a water-soluble ink, then attach a suction ring to it. After that, a specialized blade device is used to cut into the corneal flap and peel it back so that the laser can clear away corneal tissue underneath. This process corrects the shape of the cornea in less than a minute before putting the corneal flap back in place. After the procedure, we will go over LASIK Eye Surgery recovery instructions. Scrub in and let’s get started!
Root canal is a treatment to repair and save a badly damaged or infected tooth instead of removing it. The term "root canal" comes from cleaning of the canals inside a tooth's root. Decades ago, root canal treatments often were painful. With dental advances and local anesthetics, most people have little if any pain with a root canal. In fact, it's probably more painful living with a decayed tooth. Root canal alternatives include extracting the damaged tooth and replacing it with a dental implant, bridge or removable partial denture.

Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy, the cause of most scoliosis is unknown.
One thing we do know: We can live without it, without apparent consequences. Appendicitis is a medical emergency that requires prompt surgery to remove the appendix. Left untreated, an inflamed appendix will eventually burst, or perforate, spilling infectious materials into the abdominal cavity.
Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.
Three to five years after gastric bypass surgery, some patients start to regain weight because the size of their stoma (the opening at the bottom of the stomach pouch) or their stomach pouch itself has increased. This can keep you from feeling full after small meals.
To resolve this problem, our surgeons use new surgical tools to create and suture folds into the pouch, reducing its volume and at the stoma to decrease its diameter. The surgeon performs the procedure entirely through the mouth -- inserting an endoscope under heavy sedation -- so there are no external incisions into the body.
The most popular and one of the principal stains in histology is hematoxylin and eosin stain. It gives us an overview of the tissue and its structure. Hematoxylin binds with basophilic structures – for example DNA and RNA. So we can observe nuclei stained in blue or purple color. Eosin binds to acidophilic substances such as positively charged amino acid side chains. So as the result cytoplasm is pink or orange. All samples in laboratory are stained with H&E. There are several different types of hematoxylins and eosins used in histology which will give us different results.
In this video you will see, how we stain slides with different types of hematoxylins and eosins. Finally, we will compare the results.

Folic acid, which is also called folate, is a B vitamin. The best food sources of folic acid are fortified cereals. Folic acid plays an important role in the production of red blood cells and helps your baby's neural tube develop into her brain and spinal cord.
Bartter syndrome is a rare inherited defect in the thick ascending limb of the loop of Henle. It is characterized by low potassium levels (hypokalemia), increased blood pH (alkalosis), and normal to low blood pressure. There are two types of Bartter syndrome: neonatal and classic
