Summary
Slow transit constipation (STC) is a severe condition of the colon, almost exclusively affecting reproductive age women with no effective treatment. We recently found an association between STC and defects in connexin proteins in the large intestine. We aim to reveal the role of connexins and female hormones in the maintenance of normal intestinal function and their involvement in STC. The study will provide completely new perspectives in the understanding of the functional bowel disorders.
Development Of The GUTSTIM Device For The Treatment Of Intractable Constipation

Funding Amount
$380,746.00
Summary
We have developed a new treatment for chronic constipation that uses electrical stimulation through the skin similar to physiotherapy treatments for sports injuries. 20 million people (3% of children and 20% of the elderly) have chronic constipation. This proposal is to develop a simple purpose-built machine that has the best electronic properties for stimulating the intestine. The machine will be simple, easy to use and cheap, allowing safe use at home by children and the elderly.
Mechanical Factors In Normal Human Colonic Motility

Funding Amount
$650,023.00
Summary
Abnormal human colonic contractions cause significant medical, societal and financial burdens. Diagnosis and treatment of motility disorders requires an understanding of normal colonic contractility against which to measure dysfunction. Through state-of-the-art recording and analytical techniques, developed by the applicants, this project will provide the first clear description of normal human colonic motor patterns and how they are generated.
The Potential Benefit Of Resistant Starch On Zinc Retention And Its Potential For Utilisation In Infants At Risk Of Zinc Deficiency.

Summary
Resistant starch (RS) can promote absorption of minerals such as calcium and magnesium from the large intestine. As zinc deficiency in children from the developing world remains a major public health issue, we will use a rodent model to determine if RS can improve zinc absorption in growing rats with preceeding zinc deficiency. In parallel we will also determine whether infants, who are most vulnerable to the effects of zinc deficiency, have the gut bacteria required to utilise the potential and ....Resistant starch (RS) can promote absorption of minerals such as calcium and magnesium from the large intestine.

Summary
Constipation is a considerable problem, especially in the elderly; it occurs in 20-25% of people over 65 and in about 50% of people in nursing homes. It is also a significant concern for children, with up to 30% being affected. There are no adequate treatments and the majority of people are dissatisfied with their management. We have discovered a class of compounds that stimulate defecation. In this project we will test the effectiveness of these compounds to relieve constipation.
TRANSCUTANEOUS ELECTRICAL STIMULATION TO TREAT CONSTIPATION DUE TO ANORECTAL RETENTION IN CHILDREN

Funding Amount

Summary
If you don't poop, you die! Over 20% of older people have constipation. It starts in childhood in 1/100 people and lasts through life. At the Royal Children’s Hospital, Melbourne, we have been developing a physiotherapy method using electrical stimulation across the skin to treat long-term constipation. In this study we are comparing this treatment to current treatment in the most common type of chronic constipation in children.
Use Of A Novel Technique To Identify The Sensory Nerve Endings That Respond To Painful Stimuli In The Upper Gastrointestinal Tract And Characterize Their Mechanisms Of Activation

Summary
Many people experience pain in their upper gastrointestinal tract. Unlike the skin, however, we have no idea where the sensory nerve endings that detect pain are located in this part of the body, and no clear understanding of how these nerve endings are activated to cause pain. This project will utilise a novel technique recently developed by the CIA to finally identify and record directly from the sensory nerve endings that detect painful stimuli in the upper gastrointestinal tract and characte ....Many people experience pain in their upper gastrointestinal tract.
