Device for measuring the length of a stenosis

Inflammatory bowel diseases (Crohn’s disease and ulcerative colitis) affect around 1.6 million Americans and represent a sales market worth $5.6 billion worldwide. Intestinal inflammation often results in stenosis, for which a classic treatment is surgical resection. However, surgical resection is a drastic option ; if the stenosis is located on a zone accessible to endoscopy, it can be treated alternatively by dilatation, using an endoscope coupled...

Method for increasing the pool of ngn3+ endocrine progenitor cells and pancreatic endocrine cell mass

Controlling glycemia with insulinotherapy is a challenge that diabetic patients face every day. Moreover, insulinotherapy is not a curative therapy by any means. This line of treatment is only palliative and presents many limitations for the fine control of blood sugar levels. Uncontrolled blood sugar levels can result in serious damages to the eyes, nerves and kidneys of diabetic patients. However, pancreatic islets transplantation provides an altern...

New biodegradable anti-migration intestinal stent

In the US, nearly 1,5 million patients suffer from Crohn’s disease. The most common complication is digestive stenosis (50% of patients). If the stenosis measures less than 5 centimeters, an endoscopic dilatation is possible. However, it is associated with relapse rates of 30 to 50 % at 1-3 years. In this case, the patient undergoes another endoscopic dilatation or sometimes a bowel resection. The use of covered expandable metallic prostheses (used...

Enabeling/facilitating trans-cutaneous delivery of active material

Efficient trans-cutaneous delivery of active molecules is still a challenge due to the nature itself of the dermal tissue. The permeabibility of therapeutic agents can be improved by permeability agents but most of the induced delivery mechanisms induce irreversible skin alterations. We present here an original strategy consisting in using the active molecule itself to parcicipate into ist own trans-cutaneous transport, while protecting solubilizing a...

Low energy consumption backery oven

Bread baking requires a large quantity of energy – roughly 2 to 5 Mjoules /kg that is 2 to 3 times higher than the energy required for the same mass of a food product in the form of canned food for example. Furthermore food habits are changing in the world : we see in most European countries a decreasing consumption of bakery products at home while the consumption of bakery products outside home increases significantly. This market trend is suppor...
