Polish scientists have obtained and tested a compound that is more effective in inhibiting acetylcholinesterase, and at the same time less toxic than a drug commonly used in the treatment of Alzheimer's disease. In patients taking such inhibitors, neurotransmission improves, and thus - cognitive functions.
In a healthy eye, the photoreceptor cells slightly change their length when there are flashes of light. A Polish team is developing a method to record these nano-changes. As a result, it will be possible to precisely image the work of the eye and check whether everything is working properly.

The liver is highly vulnerable to the effects of a high-fat diet. Research by scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn has shown that the best way to improve liver function is to switch to an easy-to-digest diet combined with chromium supplementation.
The number of cases of Alzheimer's disease is growing rapidly, and current treatments have a limited effect. New drugs are urgently needed, but so are better diagnostic methods. As part of the Alzheimer Prediction Project, experts from Poznań are working on one of such methods.
The corpus luteum plays an important role in early pregnancy through the production of progesterone, an essential hormone needed for the proper development of pregnancy. Scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn discovered that this gland also secretes a protein called prokineticin 1, which increases lifespan and stimulates the functions of the corpus luteum.
