The endogenous system may be responsible for the delayed onset of diabetic retinopathy

About one-third of patients with diabetes mellitus (DM) develop diabetic retinopathy (DR), a leading cause of blindness in working-age individuals. DR usually develops after many years of DM and some patients do not develop DR until more than 50 years of age. New research suggests that an endogenous system that protects human retinal endothelial cells … Read more

Growing motor neurons guided by ‘love-hate relationship’ with blood vessels | Health

A new joint study shows how blood vessel genes play a critical role in motor neuron development by telling blood vessels to get out of the way. The discovery has implications for understanding diseases in which motor neuron connections are destroyed, such as amyotrophic lateral sclerosis (ALS) or spinal muscular atrophy (SMA). Now, a new … Read more

Properties of dense breasts promote cancer growth, study suggests

The risk of developing breast cancer is higher in what are known as dense breasts, which appear white on mammograms, than in non-dense breasts, which appear gray. Researchers from the University of Linköping, Sweden, have now shown that there are major biological differences between dense breasts and non-dense breasts.
