We would like to invite all members of the physiological sciences community to contribute to the success of the 37th Congress of the International Union of Physiological Sciences through your attendance. IUPS 2013 will attract many graduate students and postdoctoral fellows seeking knowledge of the latest research findings. Many of these physiologists do not have adequate funds for travel to the UK and need to be supported with travel grants in order to attend and present their data and learn about yours. To make their participation possible, we ask for your financial assistance to make it an exciting and dynamic Congress. Please take an active role in ensuring the success of the IUPS 2013. Take a few moments now to make a donation. Contributors will be acknowledged and recognised in materials distributed in conjunction with the Congress and on this website. Regardless of the amount that you contribute, your participation will make a big difference as we launch our sponsorship campaign. Thank you in advance for your support of the 37th International Congress of Physiological Sciences.
