Intestinal flora has multiple influences on human health, but researchers have revealed that it is also likely to have an effect on the body’s response to drugs. Recent research suggests that changes in the intestinal flora, caused by antibacterial and antibiotic drugs or individual differences between people, may have an effect on a person’s response to drugs including side effects. The research focused on the changes in proteins due to the condition of intestinal flora that affect the response to drugs in the liver and kidneys.

Avocados may hold the answer to beating leukemia

Avocados and leukemia

Professor Paul Spagnuolo from the University of Waterloo has discovered a lipid in avocados that combats acute myeloid leukemia by targeting the root of the disease — leukemia stem cells. Worldwide, there are few drug treatments available to patients that target leukemia stem cells. Image credit goes to: University of Waterloo

Rich, creamy, nutritious and now cancer fighting. New research reveals that molecules derived from avocados could be effective in treating a form of cancer. Professor Paul Spagnuolo from the University of Waterloo has discovered a lipid in avocados that combats acute myeloid leukemia (AML) by targeting the root of the disease – leukemia stem cells. Worldwide, there are few drug treatments available to patients that target leukemia stem cells.

Educating the immune system: A vaccine for allergies

Allergies and allergy sufferers

With the arrival of spring, millions of people have begun their annual ritual of sneezing and wheezing due to seasonal allergies. However, a Canadian research team  is bringing them hope with a potential vaccine that nudges the immune response away from developing allergies. The findings have major clinical implications since allergies and asthma are lifelong conditions that often start in childhood and for which there is presently no cure.

Diabetes drug found in freshwater potential cause of intersex fish

Scientist looking at fish in tanks

UWM School of Freshwater Sciences researcher Nicholas Niemuth studies minnows that are being raised in water heavy with pharmaceuticals to measure the drugs’ effects.

A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish –or male fish that produce eggs. The study determined exposure to the diabetes medicine metformin causes physical changes in male fish exposed to doses similar to the amount in wastewater effluent.

Could maple syrup help cut use of antibiotics?

Maple syrup covered waffles

Another reason to have those waffles… well maybe. Researchers have found that a concentrated extract of maple syrup makes disease-causing bacteria more susceptible to antibiotics. In an ever increasing antibiotic resistant world, this news is almost as sweet as the syrup (okay no more bad puns). The findings suggest that combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage.
