Protection Against Cancer May Begin During Pregnancy, Nursing
Url: http://oregonstate.edu/dept/ncs/newsarch/2006/Dec06/children.html
Omschrijving: There may be another reason
for pregnant and nursing women to eat a nutritious diet that includes generous amounts of
cruciferous vegetables like broccoli and cabbage – it could help protect their
children from cancer, both as infants and later in life.
A new study by scientists from the Linus Pauling Institute at Oregon State University,
done with laboratory mice, found that supplements of a key phytochemical found in certain
vegetables provided a very high level of protection against leukemia and lymphoma in young
animals, and also significantly protected against lung cancer during the rodent’s
equivalent of middle age.
The research, published in the journal Carcinogenesis, is one of the first of its type to
demonstrate that diet may play a protective role in a fight against cancer that may begin
– and could be won or lost – well before a person is ever born. And some of the
protective benefits may last into adulthood.

Mechanism of Black Cohosh Versus Hot Flashes Revealed

from=Releases&to=Release&id=1698&start=1159042136&end=1166818136&topic=0&dept=0
Omschrijving: The natural herb black cohosh
is commonly used by women to treat menopausal symptoms such as hot flashes, but the
molecular mechanisms underlying its action have eluded scientists -- until now.
Researchers at the University of Illinois at Chicago and the National Institutes of Health
Center for Botanical Dietary Supplements Research have discovered that black cohosh may
act on human opiate receptors, which play a role in regulating a body's temperature.
Z. Jim Wang, assistant professor of pharmacology and pharmaceutics, led the study, which
will be published in an upcoming issue of the Journal of Agricultural and Food Chemistry;
the paper is currently available on the journal's web site.
Opiate receptors are chemical sensors that respond to opiates like morphine and
endorphins, Wang said. Chemical substances with opiate activity bind to the receptors and
produce the appropriate response, including the regulation of pain, temperature and
appetite.
"We used several extracts of black cohosh and found that elements of the herb could
bind to the human 'mu' opiate receptor," Wang said. "The opiate receptor system
affects several aspects of female reproductive neuroendocrinology, such as the levels of
sex hormones and neurotransmitters that are important for temperature regulation."
Black cohosh (known as both Actaea racemosa and Cimicifuga racemosa) is a member of the
buttercup family. A perennial plant, it is native to North America. It has been used by
Native Americans to treat malaise, gynecological disorders, kidney ailments, malaria,
rheumatism and sore throat, as well as colds, cough, constipation, hives and backaches,
and to induce lactation.
Antibiotic Inhibits Cancer Gene Activity

from=Releases&to=Release&id=1577&start=1159042136&end=1166818136&topic=0&dept=0
Omschrijving: A little-known antibiotic
shows early promise as an anti-cancer agent, inhibiting a gene found at higher-than-normal
levels in most human tumors, according to researchers at the University of Illinois at
Chicago College of Medicine.
"We chose to target a gene believed to be over-expressed in cancer cells to screen
for promising anti-cancer agents," said Andrei Gartel, assistant professor of
medicine and of microbiology and immunology at UIC and principal investigator on the
study.
The FoxM1 gene is responsible for turning on genes needed for cell proliferation and
turning off genes that block proliferation. Uncontrolled proliferation is characteristic
of cancer cells.
The researchers developed a new screening system, based on a naturally fluorescent protein
called luciferase, to identify small molecules that inhibit proteins that turn genes on
and off. Using this system, they identified an antibiotic, siomycin A, that specifically
targets FoxM1 without affecting other cell functions.
Recurrence of a Flu Pandemic Similar to Infamous 1918 Flu Could Kill 62 Million
Url: http://www.hsph.harvard.edu/press/releases/press12212006.html
Omschrijving: In recent years, health
professionals and the general public alike have been acutely aware of the potential
ravages that could result from a flu pandemic. Although many people might still recall the
pandemics of 1968 and 1957, it is the infamous 1918-1920 pandemic--and the possibility of
a recurrence on that scale--that causes the most trepidation.
Strangely, researchers still don't know exactly how many people died from this particular
strain of the flu virus in that pandemic, and they know even less about how mortality
rates varied in different parts of the world. In fact, most historic information is based
on eyewitness accounts and not on statistical analysis. Now, a team of researchers from
Harvard School of Public Health (HSPH) and the University of Queensland in Australia have
re-analyzed data from 27 countries around the world to estimate both the global mortality
patterns of the 1918 pandemic and, based on 2004 population data, how a similar pandemic
would affect the world today.
Cluster of journals publish MSU, collaborator findings on common parasite
Url: http://www.montana.edu/cpa/news/nwview.php?article=4345
Omschrijving: Montana State University
researchers and their collaborators are gaining widespread attention for discoveries
involving a common parasite that can threaten everyone from babies to AIDS patients.
Their findings about Toxoplasma gondii and toxoplasmosis were published recently in three
major scientific journals. Nature published a paper Dec. 20 in its advanced online
version.
Toxoplasmosis is a disease caused by the parasite Toxoplasma gondii. Symptoms usually
appear only in people with weakened immune systems, but on rare occasions, healthy people
suffer serious eye and central nervous system problems from toxoplasmosis. Their babies
can have birth defects. White said toxoplasmosis also may be linked to some cases of
schizophrenia and bipolar disease. It can kill livestock and has devastated efforts to
restore sea otters near Monterey, Calif. Because it's common, yet complex, toxoplasmosis
is a potential weapon for bioterrorists.
Inflammatory bowel disease doubles risk of pregnancy complications

Omschrijving: Inflammatory bowel disease
roughly doubles the chances of pregnancy complications, reveals research published ahead
of print in Gut.
Inflammatory bowel disease, or IBD for short, is an umbrella term for the inflammatory
disorders of Crohn's disease and ulcerative colitis.
The research team re-analysed 12 studies published over the past 20 years, which assessed
the impact of IBD on pregnancy and birth.
In all, the dozen studies, drawn from an extensive search of published material, involved
almost 4000 women with IBD and more than 320, 000 people without the condition, with whom
they were compared.
Around two thirds of the women had Crohn's disease; the remainder had ulcerative colitis.
The results showed that women with IBD were almost twice as likely to have a child born
prematurely, and more than twice as likely to have a child born below normal weight.
Premature and low birthweight babies run the risk of developmental problems and a greater
likelihood of serious chronic illness.
Women with IBD were 1.5 times as likely to have had a caesarean section as their healthy
peers, especially those with Crohn's disease.
And the rate of congenital birth defects in babies born to mothers with IBD was more than
twice as high.
If a woman becomes pregnant during an active bout of disease the risks of pregnancy
complications are likely to be greater, suggest the authors.

Single protein can determine severity of toxoplasma infections, Stanford study
shows
Url: http://mednews.stanford.edu/releases/2006/december/toxoplasma.html
Omschrijving: The unusual ability of the
organism Toxoplasma to infect and reproduce inside almost all warm-blooded animals has led
scientists to wonder about the tricks it uses so successfully to subvert the behavior of
cells. Now, a team of Stanford University School of Medicine researchers, led by John
Boothroyd, PhD, has shown for the first time how Toxoplasma manages to be so effective:
They documented how it injects a particular protein into the cell it infects and how that
protein then travels to the cell’s nucleus—where it blocks the cell’s
normal response to invasion.
High doses of lithium-like drugs may impair neuronal function
Url: http://www.eurekalert.org/pub_releases/2006-12/uonc-hdo121906.php
Omschrijving: New laboratory research
suggests that lithium and other drugs that inhibit a particular enzyme, GSK-3 beta, should
be used with caution in treating Alzheimer's disease because too high a dose can impair,
rather than enhance, neuronal function. Lithium is currently in clinical trials for
treating Alzheimer's. Pharmaceutical companies are interested in producing other GSK-3
beta inhibitors for the disease because these drugs are relatively easy to make and
lithium has been shown to be safe in low doses in treating people with manic-depressive
illness, said Dr. William D. Snider, professor of neurology, cell and molecular physiology
at the University of North Carolina at Chapel Hill's School of Medicine. "People
might think that if you make the inhibitor stronger and stronger, that would be better.
Our in-vitro experiments show that you will have to be careful with how you use GSK-3 beta
inhibitors, because if you use too much, it will interfere with and possibly kill
neurons," said Snider, who also is director of UNC's Neuroscience Center
Blood transfusions may raise infection risk for heart surgery patients —
especially women, U-M study finds
Url: http://www.med.umich.edu/opm/newspage/2006/bypass.htm
Omschrijving: Blood transfusions save the
lives of millions of heart surgery patients and others each year. But a new study suggests
that patients who receive transfusions during heart bypass surgery have a higher risk of
developing potentially dangerous infections, and dying, after their operation.
In fact, this increased risk may help explain a longstanding medical mystery: why women
bypass patients are more likely than men to die in the first few months after surgery.
Women are more likely to receive blood during heart bypass operations, which are performed
on more than 465,000 Americans each year.
Androgen Therapy May Slow Progress of Alzheimer's Disease
Url: http://www.sfn.org/?pagename=news_121906a
Omschrijving: Experiments on mouse models
of Alzheimer's disease (AD) suggest that treatment with male sex hormones might slow its
progression. The findings, published in the December 20 issue of The Journal of
Neuroscience, provide new insight into the relationship between testosterone loss and AD,
which affects 4.5 million Americans.
Senior author Christian Pike, PhD, of the University of Southern California (USC), with
colleagues at USC and the University of California, Irvine, sought to better understand
the role hormones play in aging and disease. Recent studies had already established a link
between testosterone loss in men and AD due to natural aging.
The research team established a correlation between low testosterone and elevated
beta-amyloid (Aß), a protein that accumulates abnormally in AD patients. This finding,
they say, suggests that testosterone depletion in aging men may be a risk factor for AD by
promoting accumulation of Aß in the brain. Testosterone, the primary male sex hormone, is
one in a group of related steroid hormones referred to as androgens. Recent studies
suggest that androgens may lower Aß levels.
"This study raises the possibility that androgen replacement therapy might lower the
risk for Alzheimer's, but this is far from proven," says Sam Gandy, MD, PhD, chair of
the Alzheimer's Association's Medical and Scientific Advisory Council and director of the
Farber Institute for Neurosciences at Thomas Jefferson University. "Because
testosterone is rapidly converted to estrogen after entry into neurons, the new data are
logical, and they dovetail well with historical data."
Higher occurrence of Parkinson's linked to low LDL cholesterol
Url: http://www.eurekalert.org/pub_releases/2006-12/uonc-hoo121906.php
Omschrijving: People with low levels of LDL
cholesterol are more likely to have Parkinson's disease than people with high LDL levels,
according to University of North Carolina at Chapel Hill researchers.
LDL stands for low-density lipoprotein cholesterol; low levels of LDL cholesterol are
considered an indicator of good cardiovascular health. Earlier studies have found
intriguing correlations between Parkinson's disease, heart attacks, stroke and smoking.
"People with Parkinson's disease have a lower occurrence of heart attack and stroke
than people who do not have the disease," said Dr. Xuemei Huang, medical director of
the Movement Disorder Clinic at UNC Hospitals and an assistant professor of neurology in
the UNC School of Medicine. "Parkinson's patients are also more likely to carry the
gene APOE-2, which is linked with lower LDL cholesterol." And for more than a decade,
researchers have known that smoking, which increases a person's risk for cardiovascular
disease, is also associated with a decreased risk of Parkinson's disease.
CeRPTA develops new gluten-free bread
Url: http://www.eurekalert.org/pub_releases/2006-12/uadb-cdn121906.php
Omschrijving: Researchers at the Food
Technology Plant Special Research Centre (CeRPTA) have for the first time developed a
completely gluten-free bread that is of a much higher quality than products currently
available for coeliacs. The product was 100% successful in the tests carried out. The
resulting product has an increased nutritional value, a longer useful life and a similar
texture to traditional bread.
Coeliac disease is the permanent intolerance of gluten, forcing sufferers to follow a
strictly gluten-free diet for their whole life. Gluten is a protein contained in certain
cereals such as wheat, rye, barley, triticale (hybrid of wheat and rye) and possibly oats.
Eating gluten produces atrophy to the villi in the intestine. Food is not absorbed,
causing an inflammatory reaction. It affects genetically predisposed individuals,
including children and adults.
It currently affects approximately 1% of the population. The number of coeliacs is growing
rapidly, thus significantly increasing the number of consumers of gluten-free products.

Less sugary drinks during childhood may cut disease risk
Url: http://www.eurekalert.org/pub_releases/2006-12/ps-lsd121806.php
Omschrijving: Symptoms of heart disease and
diabetes usually seen in adults are increasingly being found in adolescents according to a
longitudinal study, which suggests that reducing the intake of sugar-sweetened beverages
during childhood may lessen the risk of chronic disease in later life. "Research on
obesity and associated problems such as hypertension and type-2 diabetes has largely dealt
with adults," says Alison Ventura, doctoral candidate at Penn State's Center for
Childhood Obesity Research. "But with increasing rates of obesity in children, we are
seeing these problems at much younger ages."
Ventura and her colleagues Eric Loken, assistant professor of human development and family
studies, and Leann Birch, professor of human development and family studies, are studying
the clustering of traits such as insulin resistance, abdominal obesity, hypertension, and
high triglycerides combined with low HDL – good cholesterol – that are thought
to be related to cardiovascular disease and diabetes in adults.

Omschrijving: Question: I am having a very
difficult time defending the benefits of a diet rich in saturated fat. I attend Bastyr
University, a naturopathic medical school, and through all my nutrition classes, saturated
fat has been deemed unhealthy and detrimental to one's health. For instance, my Diet and
Nutrient Therapy class professor cites a 2002 article in the British Journal of Nutrition,
"Acute effects of a meal fatty acid composition on insulin sensitivity in healthy
post-menopausal women" as showing that saturated fat reduces insulin sensitivity,
thereby contributing to type-2 diabetes. He also cited a 2002 study in Diabetologia,
"Substituting dietary saturated fat with polyunsaturated fat changes abdominal fat
distribution and improves insulin sensitivy." I would be very interested in your
comments on these studies and your views on saturated fat and diabetes.
The importance of saturated fats for biological functions
Url: http://www.greenclippings.co.za/gc_main/article.php?story=20061204110130622
Omschrijving: Most Westerners consume very
little myristic acid because it is provided by coconut oil and dairy fats, both of which
we are told to avoid. But myristic acid is a very important fatty acid, which the body
uses to stabilize many different proteins, including proteins used in the immune system
and to fight tumors. This function is called myristoylation; it occurs when myristic acid
is attached to the protein in a specific position where it functions usefully. For
example, the body has the ability to suppress production of tumors from lung cancer cells
if a certain genetically determined suppressor gene is available. This gene is called fus1
and is a protein that has been modified with covalent addition of the saturated fatty acid
myristic acid. Thus, the loss of myristic acid from the diet can have unfortunate
consequences, including cancer and immune system dysfunction. Lauric acid has several
functions. It is an antimicrobial fatty acid on its own and as a monoglyceride. It also
has the function of stabilization when it is attached to certain proteins in a similar
fashion to myristic acid and palmitic acid.
Healthy Alternative to Conventional Infant Formula

Omschrijving: The advice to make homemade
baby formula as an alternative to commercial formula has been one of the most
controversial positions taken by the Weston A. Price Foundation -- and also one that has

While government officials and orthodox pediatricians are often appalled at the thought of
a parent mixing up baby formula -- and one based on raw milk, no less -- the feedback we
have received from parents has been extremely positive.
Some breastfeeding advocates have also criticized our stance, claiming that by providing a
more healthy alternative to commercial formulas, we are discouraging breastfeeding. Make
no mistake: the best food for baby is breastmilk from a healthy mother.

Url: http://www.webmd.com/content/article/98/104684.htm?src=rss_cbsnews
Omschrijving: For decades we've been told
that eating saturated fat is bad for our hearts, but new research shows that the opposite
just might be true for those at risk for heart disease. In a study involving older women
with heart disease, women who ate the most saturated fat had the least atherosclerosis
disease progression in coronary arteries over a three-year period.

Omschrijving: Well, that's what the drug
companies and low-fat food manufacturers who make billions in revenue each year as a
direct result of the reigning cholesterol paranoia would like you to believe! It's also
what 'respectable' health authorities - who receive millions in 'donations' from food and
drug companies in one hand, while disseminating allegedly 'impartial' health advice to the
public on the other - would have you believe.
Statines effect study
Url: http://medicine.ucsd.edu/ses/
Omschrijving: We are seeking to get
information from people who have had adverse responses to statins or to other
cholesterol-lowering drugs, and also from people who have done well on these drugs. We can
learn from this information, perhaps gaining a better understanding of who may be at risk
and who will do well with statins; and what to expect in people who develop adverse
effects (e.g. how quick or long recovery may take; what factors predict or facilitate
recovery).
Women and statines
Url: http://medicine.ucsd.edu/ses/statin_information.htm
Omschrijving: As of this writing, no study
has shown statins or any other cholesterol drugs to lower overall mortality in women; and
epidemiologically, cholesterol in women does not have the same relation to mortality as in
men. Although higher cholesterol is linked to a higher rate of heart attacks per se, it is
not linked to overall cardiovascular death or to overall death; indeed, lower cholesterol
is linked to a slightly higher risk in some studies. Consistent with this, there is a
decided reduction in heart attacks in women with statins, but the death rate overall -- or
even cardiovascular death rate - has not been shown to be reduced. It is possible that
there are subgroups of women for whom statins confer benefit exceeding risk, but this has
never been demonstrated.
Athens professor hypothesizes stress and diabetes link
Url: http://www.decaturdaily.com/decaturdaily/news/061224/link.shtml
Omschrijving: Malcolm Cort, assistant
professor of sociology, said blacks have a high incidence of type II diabetes. Cort is

stereotypes that produces stress, and initiates an accumulation of abdominal fat
associated with heart disease and type II diabetes.
Low-fat diet can help prevent breast cancer recurrence
Url: http://www.poughkeepsiejournal.com/apps/pbcs.dll/article?AID=/20061224/NEWS06/612240309
Omschrijving: The study of more than 2,400
women, ages 48 to 79, found the rate of cancer recurrence after five years was 9.8 percent
among women who ate a low-fat diet (about 33 grams of fat per day) and 12.4 percent among
those who ate a standard diet (about 52 grams of fat per day).
Welsh scientists get breakthrough in fight against Alzheimer's
