Help people adapt to a new time zone or shift work more easily. Prevents mountain sickness Viagra could help mountain climbers breathe easier and prevent them becoming unwell, another study suggested. Researchers at Justus-Liebig University in Germany tested 14 healthy volunteers, who had their pulmonary artery pressure and oxygen levels logged in a lab.The same checks were repeated at the Mount Everest base camp, at around 17,000ft.Half had been given sildenafil, while half acted as the control group. Results, published in the journal Annals of Internal Medicine in 2004, show that the drug decreased pressure in the lungs’ blood vessels in both lab and mountain conditions.As a result, climbers could better tolerate hypoxia — low oxygen levels, which causes altitude sickness — while scaling the Himalayan peak. Shrinks cancerous tumoursPopping Viagra could make cancer treatment more effective, if separate research from 2022 is to be believed.Academics at Southampton University found PDE5 inhibitors — the class of erectile dysfunction drugs that includes Viagra, Cialis and Levitra — make oesophageal tumours more vulnerable to chemotherapy. The drugs were found to target cancer-associated fibroblasts — cells that surround tumours, support their growth and help them build up resistance to chemo.PDE5 inhibitor drugs relax the structure of the fibroblasts so they become floppy, meaning they can no longer help the tumour to thrive and grow. When the scientists tested PDE5 inhibitor drugs on oesophageal cancer cells in the lab and on mice, they found that chemo was effective in 75 per cent of cases. For comparison, chemo usually only works in 20 per cent of oesophageal cancer patients. READ MORE>>>>> Post navigation
