• Stem cell aging: what
bleach can
teach
Intracellular oxidants may contribute to overall lifespan, in part by
affecting
stem cells. The connection between oxidants and aging now gains
strength in a
study of hematopoietic stem cells, which respond to oxidants by
activating a
pathway leading to stem cell exhaustion.

BIOMEDICINE: Lowering LDL--Not Only How Low, But How Long?
People with a mutation in a proteolytic enzyme are at a substantially
lower
risk for coronary heart disease because of their lifelong reduction of
plasma
low-density lipoprotein. Authors: Michael S. Brown, Joseph L. Goldstein

• When it comes
to the mind, use it or lose it
New research suggest that lifestyle choices can be as important as
genetics in
determining how our brains age and that simple changes can help combat,
and
sometimes reverse, the memory loss that comes with getting older.
• 7 Ways to Help
Curb Cancer
Death Risk
A new report from the American Cancer Society estimates that at least
half of
all cancer deaths "could in principle be avoided" with some lifestyle
changes.
• Ovary Removal
May Up
Dementia Risk
Women who undergo ovary removal before menopause may have an increased
risk of
dementia, a Mayo Clinic study suggests.
• Aspirin equally
heart-protective in men and women
"Women are clearly benefiting from taking aspirin and should continue
to
take it to improve their cardiovascular health," Dr. Diane M. Becker
states in a Johns Hopkins press release. "Aspirin has been proven by
all
previous studies to lower the risk of stroke and, as our latest
findings show,
it also reduces platelet aggregation that can lead to potentially fatal
clots
in blood vessels."
• HDL cholesterol
level
predicts heart events
NEW YORK (Reuters Health) - Levels of HDL cholesterol -- the good
cholesterol
-- can be used to predict major adverse coronary events, independent of
other
heart and circulatory risk factors, according to a report published
this month.
• Breast Size
Studied As
Cancer Risk
Few women have perfectly symmetrical breasts, but larger differences in
size,
according to a study in the U.K., might be a risk factor for breast
cancer. The
American Cancer Society calls the findings "interesting" but
"very preliminary."
• X Chromosomes
Key To Sex
Differences In Health
Females have two X chromosomes and males only have one -- and this
simple fact,
along with the occurrence of what geneticists call mosaicism, may not
only
explain why women are less susceptible than men to certain genetic
diseases,
but also may account for the female prevalence in the incidence of
other
conditions and even sex differences in behavior, according to a special
communication in the March 22/29 issue of JAMA, a theme issue on
women's
health.
