Brief Summary

A research study to find out more about a specific white blood cell called a dendritic cell. These cells are found in a layer of fat in the body called the omentum. The omentum is a layer of fat that covers the bowels (intestines) and protects them. The purpose of this study is to allow us to compare dendritic cells in normal weight individuals to the dendritic cells of people who are extremely overweight. These cells will be collected from the omentum, the layer of fat that covers and protects the bowels (intestines), from the mesentery, which is another layer of fat that surrounds the intestines directly, and from the subcutaneous tissue, which is the layer of fat just under the skin.

Non Interventional Study in Patients With Open Angle Glaucoma and/or Ocular Hypertension Treated With XALATAN®

Completed

All adult subjects 18 years or greater being seen in the minimally invasive surgery clinic for elective laparoscopic surgery will also be screened.

These will be subjects who are non-obese (BMI\<30) and undergoing laparoscopic surgery for a different indication such as hernia repair or cholecystectomy. These will be patients who are undergoing elective procedures to minimize the impact an acute inflamed abdomen may have on the fat cells.

You may not qualify if:

Women who are pregnant or planning to become pregnant will be excluded from this study. Gastric banding cannot not be performed on pregnant women.
