Immunosuppression study helps understand why some prostate cancer treatments do not work as expected
by Tampere University On the left is a tissue sample from the prostate stained with hematoxylin and eosin. Hematoxylin stains the nuclei blue or purple because it binds to DNA, and eosin stains the cytoplasm and proteins red or pink. This method is used in the diagnosis of prostate cancer. Visium technology (in the centre) allows...

The anatomy of a hot flush. Can it really make your head steam?
by Michelle Spear, The Conversation Credit: Pixabay/CC0 Public Domain A hot flush is a phenomenon as disruptive as it is commonplace. One moment, life proceeds as usual. The next, a wave of heat rises, spreading from the chest to the face—leaving behind flushed skin and beads of sweat. For many, this sudden warmth is accompanied by...

Severe COVID-19 may be a risk factor for multiple sclerosis
by Örebro Universitet Credit: CC0 Public Domain COVID-19 may be a risk factor for multiple sclerosis (MS). This has been shown by new research at Örebro University and Örebro University Hospital, Sweden. The study is published in the journal Brain Communications. “We saw a raised risk of MS among people who had severe COVID-19. However, only an extremely...
