C. Normally, restoring the frozen organs has been failed because the cell membranes are always damaged by the expanded volume of water when it freezes. However, this problem has been overcome by using a novel cryoprotectant liquid which is non-toxic. The liquid does not damage cells as it freezes and cause very small osmotic pressure across cell membranes. So if any one want to sleep for 50 or 100 years and weak up to see the year 2100, it might be possible in the near future. 28 September 1996.
Cervical cancer is known to be related to human papilloma virus, a sexually transmitted agent.
A case-control study conducted in three hospitals in Thailand found that wives of men who frequently visited prostitutes sometime in their lives with infrequent use of condoms tend to be at higher risk for cervical cancer. The women in this study were between the ages of 21 and 60 years old who were married and have all reported of having only one sexual partner. A latent period between the women's likely initial exposure to a sexually transmitted oncogenic agent and their diagnosis of cervical cancer was about a quarter of a century. Regular use of condoms by customers of prostitutes can reduce the number of invasive cervical cancer cases in the general population of Thailand by at least one-fourth.
