Random Errors in DNA Replication Play Major Role in Cancer

English

Briefly, human cancer is traditionally known to occur from heredity or environmental sources, but researchers found errors in the DNA replication of many healthy cells that has an effect on cancer and they called that factor ‘’R’’ or random mutations.

Random Errors in DNA Replication Play Major Role in Cancer

The main result of this article is that “nearly two-thirds of mutations in human cancers are attributable to random errors that occur naturally in healthy, dividing cells during DNA replication.”  Before this result, the scientific community believed a much bigger part of the DNA mutations were cause heredity or environmental source. According to one of the researcher, the implication of the R (random) mutation was underestimated he believes that their result will increase the attention given to it.

Random Errors in DNA Replication Play Major Role in Cancer ... What Else ?

English

A lot of element can cause a cancer but one of them is particularly grabbing our attention: the “R mutations” or “random mutations”. In fact, two-thirds of mutations in human cancers are engendered by a random error in DNA replication and this happen even when the cells are completely healthy. This means that heredity and environment have a greatly lower impact on cancer mutation than everybody always thought. Up until now, R mutations have been neglect but these mutations need to be taken very seriously.

The Medicine of Older TImes

       During the trip to the Osler Library that was on the McGill campus my class and I had the opportunity to work with some old artifacts which happened to be books. The book my group worked with was William Cockburn’s," Sea Diseases: Or A Treatise Of Their Nature, Caufes, And Cure. Also, An Essay On Bleeding In Fevers;". What was great about the book was the fact that the information that was portrayed throughout the pages was about how they discovered diseases that happened while men sailed the seas.

Locking Up People with Mental Health: West Africa vs. Quebec

Every country struggles to take care of people with mental health problems. Now, in West Africa in particular “mental health is an incredible neglected issue […] [because] there are so many competing priorities”. In this article written by Carey Benedict, on October 11th 2015, the lack of resources to treat mental illnesses is very clear.

If We Can Edit Genes from Butterflies, Can We Do the Same With Humans?

English

The article that I read from News Activist talks about how scientists have been able to change the painting genes from butterflies using the technology of CRISPR. With this, scientists might be able to change the specific patterns in the brain by turning on and off human genes. This is a big revolution in the world of genetics that must be known!

Cigarette: slaying with its third-hand smoke

English

Cigarettes are more harmful then what we thought and that is already surprising! It’s well known how cigarettes have a poisonous effect in health as the damages it provokes include blood vessels, reproductive organs, mouth, lungs, heart, and many other organs. Certainly, the number of deaths caused by smoking cigarettes is higher than alcohol in many countries. Though, not only its first-hand smoke kills, its second-hand smoke can be very dangerous causing the same number of diseases. But how is this a new discovery? These effects have been known for a while.

Could the Zika Virus Cure Brain Cancer?

English

In the past couple of years, the Zika virus made headlines as the world grew more and more concerned about the health effects it could have on us humans.  During that time, the scientific community has been hard at work trying to find an efficient treatment, but the solution to the Zika virus remains a mystery to this day. However, the extensive research on this topic has led to a brand-new discovery: the Zika virus could help cure brain cancer.
