The results of a new study show that changes in the design of cigarette with the passage of time can raise the risk for certain types of lung cancer particularly in the US smokers.
Dr. David Burns, the lead author of the study, says in a tobacco research meeting that nearly 51% cases of lung cancer are because of these changes.
It’s not happening for the first time that researchers have presented such results as many other previous studies have shown similar sort of results regarding different types of cigarettes that also include low-tar cigarettes. The interesting finding was that US as well as Australia both have switched to well-known milder cigarettes, but the risk of adenocarcinoma, a lung tumor was found higher in the US smokers than the Australian.
According to researchers, some common antidepressants can decrease the fertility of some men, as they cause damage in the DNA of their sperm.
In this small study, the researchers gave paraoxetine( Paxil or Seroxat) to 35 healthy men and they found that the ratio of fragmented DNA sperm cells rose from 13.8 percent to 30.3 percent after four weeks of treatment on average basis.
Almost the same levels of DNA damage are associated to problems with embryo capability in those couples who try to have children.
The research has been reported in the New Scientist magazine and it is expected to be presented in November at a meeting of the American Society for Reproductive Medicine.
Some experts conclude that only a substantial proportion of men on paroxtine may have to face fertility related damage, as it adversely affects the DNA integrity of sperm.
