Herbicide atrazine linked to reproductive dysfunction

An international team of researchers has reviewed the evidence linking exposure to atrazine - an herbicide widely used in the U.S. and more than 60 other nations - to reproductive problems in animals. The team found consistent patterns of reproductive dysfunction in amphibians, fish, reptiles and mammals exposed to the chemical.

Second biopsy for suspected recurrent breast cancer can alter treatment

A second, larger clinical research study led by breast cancer specialists at Princess Margaret Hospital (PMH) has again proven that comparing a new biopsy of progressing or recurring cancer with that of the original cancer can dictate a change in treatment.

Serotonin instructs scar forming cells to switch off regeneration in chronic liver disease

In liver disease, extent of tissue damage depends on the balance between the generation of scar tissue and the regeneration of new liver cells. In a significant minority of people who get injury to their organs instead of repairing them, they form scars.

Caregivers have stress reactions that put them at greater risk for physical health problems

When a person with mild cognitive impairment is agitated or restless, caregivers can expect to find they are more edgy as well.

Knocking out one copy of IGF1 receptor fails to increase life span of male mice

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even if their bodies were less responsive to insulin, the hormone that lowers blood sugar.
