For patients treated for stage I seminoma who choose surveillance rather than undergoing adjuvant therapy, there have been no randomized trials to determine the optimum frequency of scans and visits, and the schedules vary very widely across the world, and within individual countries. In the UK there is an ongoing clinical trial called TRISST. [35] [36] This is assessing how often scans should take place and whether magnetic resonance imaging (MRI) can be used instead of CT scans. MRI is being investigated because it does not expose the patient to radiation and so, if it is shown to be as good at detecting relapses, it may be preferable to CT.

2) Irreversible adaptation to sperm competition . It has been suggested that the ancestor of the boreoeutherian mammals was a small mammal that required very large testes (perhaps rather like those of a hamster ) for sperm competition and thus had to place its testes outside the body. [44] This led to enzymes involved in spermatogenesis, spermatogenic DNA polymerase beta and recombinase activities evolving a unique temperature optimum, slightly less than core body temperature. When the boreoeutherian mammals then diversified into forms that were larger and/or did not require intense sperm competition they still produced enzymes that operated best at cooler temperatures and had to keep their testes outside the body. This position is made less parsimonious by the fact that the kangaroo , a non-boreoeutherian mammal, has external testicles. The ancestors of kangaroos might, separately from boreotherian mammals, have also been subject to heavy sperm competition and thus developed external testes, however, kangaroo external testes are suggestive of a possible adaptive function for external testes in large animals.

One thing that many people seem to agree on is that high temperatures can cause BPA to leach into the food or beverage. In one study, boiling water was placed in hard plastic water bottles. The rate of release of BPA with the boiling water was compared with room-temperature water. With room-temperature water, BPA was released at a rate of to nanograms per hour. The BPA was released 15 to 55 times faster with the boiling water, with a rate of 8 to 32 nanograms per hour. The concern about this has led Canadian retailers to pull all baby bottles made with BPA from the shelves. In the United States, many manufacturers and retailers are beginning to do the same.
