In a former life I loved science. I majored in zoology, with a human biology emphasis. I came into the major my junior year of college. I'd been a chemical engineering major who burned out, turned to anthropology for solace and interest, but returned to science because I'm just not the kind of person who enjoys an easy A. Give me a struggle for a B and I'm much happier. My core ...

... of Medicine of Yeshiva University has found a clear link between living to 100 and inheriting a hyperactive version of an enzyme that rebuilds telomeres – the tip ends of chromosomes. The findings appear in the latest issue of the Proceedings of the National Academy of Sciences. In investigating the role of telomeres in aging, the Einstein researchers studied Ashkenazi Jews because they are a ...

Holy unrecognizable Jennifer Grey on New Adventures of Old Christine, Batman! Sure, we've all known about her disfiguring nose job of many moons ago, but now thanks to some apparent Botox and over-tweezing of the eyebrows, I would not have known her were it not for her voice! Poor Baby... This is going to be a hodgepodge, my friends. A female coworker posited the following earlier today: ...

*snicker* You gotta love anthropology! Here's an article to keep one pondering the great mysteries of life and genetics through the lense of physical anthropology (my favorite). Nature or nurture may not be so heatedly debated now. Of course, this is just one of the many theories that opens one's eyes... My favorite study is the one about children getting their intelligence from their ...

Background: The well-known typical fusion gene BCR/ABL can be observed in connection with a complex translocation event in only 2-10% of cases with chronic myeloid leukemia (CML). As nowadays most CML cases are treated with Imatinib, variant rearrangements have in general no specific prognostic significance, though the emergence of therapy resistance remains to be studied. Results: Here we report ...

Story Summary: The findings appear in the latest issue of the Proceedings of the National Academy of Sciences. Telomeres play crucial roles in aging, cancer and other biological processes. Each time a cell divides, its telomeres erode slightly and become progressively shorter with each cell division. As we suspected, humans of exceptional longevity are better able to maintain the length of their ...

HI Carolyn!  Loving that attitude of yours   My mom had a SCT for AML M1.  Her sister ended up matching, but there were 5 of them.  Her condtioning pre SCT consisted of 11 Total body radiation and chemo for 3 days.  Overall, the radiation was a breeze for my mom, and the chemo only gave her some nausea. After transplant she had the typical mouth sores, loss of appetite, and overall ...
