Rocking embryos helps IVF

I'm not surprised by that gently rocking embryos (and maybe singing to them?) improved IVF success, but it also argues for getting yourself healthy and letting Mother Nature do her thing. I wonder if there will be any long term consequences from IVF...

From CBC news Canada:

(HealthDay News) - Scientists say they boosted the success of in vitro fertilization in mice by gently rocking embryos before implanting them into the womb.

No evidence yet proves that the same technique would work with human embryos, but authors of a new study hope it might do just that.

"By making the cells feel more at home, we get better cells, which is key to having better infertility treatment," said study co-author Shu Takayama, an associate professor in the University of Michigan's department of biomedical engineering.

The idea of the research is to mimic the motion that an embryo feels traveling through the fallopian tube to the uterus. Human embryos created with the assistance of in vitro fertilization don't get the benefit of such exposure.

Horrible Bpa source: receipts!

Just to show how chemicals have really invaded every corner of our lives, now they've found there's the endocrine-disrupting BPA (no good for anyone's fertility) in RECEIPTS. I had done a few posts on BPA in polycarbonate SIGG bottles, but this is even more serious.

From Science News:

While working at Polaroid Corp. for more than a decade, John C. Warner learned about the chemistry behind some carbonless copy papers (now used for most credit card receipts) and the thermal imaging papers that are spit out by most modern cash registers. Both relied on bisphenol-A...

“When people talk about polycarbonate bottles, they talk about nanogram quantities of BPA [leaching out],” Warner observes. “The average cash register receipt that's out there and uses the BPA technology will have 60 to 100 milligrams of free BPA.” By free, he explains, it’s not bound into a polymer, like the BPA in polycarbonates. It’s just the individual molecules loose and ready for uptake.

As such, he argues, when it comes to BPA in the urban environment, “the biggest exposures, in my opinion, will be these cash register receipts.” Once on the fingers, BPA can be transferred to foods. And keep in mind, he adds, some hormones — like estrogen in certain birth-control formulations — are delivered through the skin by controlled-release patches. So, he argues, estrogen mimics like BPA might similarly enter the skin.

Antidepressants may lead to lactation difficulties

Yes, not being able to breast feed can be REALLY depressing...

From Newswise, the journalists'-only web site:

Newswise — According to a new study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM), women taking commonly used forms of antidepressant drugs may experience delayed lactation after giving birth and may need additional support to achieve their breastfeeding goals.

Breastfeeding benefits both infants and mothers in many ways as breast milk is easy to digest and contains antibodies that can protect infants from bacterial and viral infections. The World Health Organization recommends that infants should be exclusively breastfed for the first six months of life. This new study shows that certain common antidepressant drugs may be linked to a common difficulty experienced by new mothers known as delayed secretory activation, defined as a delay in the initiation of full milk secretion.

“The breasts are serotonin-regulated glands, meaning the breasts’ ability to secrete milk at the right time is closely related to the body’s production and regulation of the hormone serotonin,” said Nelson Horseman, PhD, of the University of Cincinnati and co-author of the study. “Common antidepressant drugs like fluoxetine, sertraline and paroxetine are known as selective serotonin reuptake inhibitor (SSRI) drugs and while they can affect mood, emotion and sleep they may also impact serotonin regulation in the breast, placing new mothers at greater risk of a delay in the establishment of a full milk supply.”

Cleaning chemicals, etc., cause pediatric dermatitis

When are people going to realize that harsh cleaning chemicals aren't good for you? We use baking soda and tea tree oil, works rather well and it's cheap! From Newswise,, the journalists' only new site;

Newswise — Considered a dermatological nuisance that was long gone, skin irritations caused by toilet seats appear to be making a comeback in pediatricians’ offices, according to research led by Johns Hopkins Children’s Center investigator Bernard Cohen, M.D.

“Toilet seat dermatitis is one of those legendary conditions described in medical textbooks and seen in underdeveloped countries, but one that younger pediatricians have not come across in their daily practice,” says Cohen, director of pediatric dermatology at Hopkins Children’s. “If our small analysis is any indication of what’s happening, we need to make sure the condition is on every pediatrician’s radar.”

Analyzing five cases from the United States and India in the February issue of the journal Pediatrics, Cohen and colleagues said the culprits responsible for the reemergence of the condition are harsh cleaning chemicals and exotic wooden toilet seats — making a comeback as bathroom décor —especially seats covered with varnishes and paints.

Cohen says children can develop irritation after several uses of a wooden seat or repeated exposure to residue from harsh cleaning chemicals. He urges pediatricians to inquire about toilet seats and cleaners used both at home and at school any time they see a toddler or a young child

Reasons why Sex is Good for You

This came via Lifehacker.

2. Sex helps you forget
Oxytocin, which triggers orgasm, has an amnesic effect that lasts up to five hours. So for a period of time you forget that he maxed out your Visa card or she was an hour late getting home from work. Women get an additional benefit. During orgasm that parts of the brain that govern fear, anxiety, and stress are switched off. (Faking orgasm gives no such benefit.)

5. Heightened sense of smell
After sex, production of prolactin surges, causing stem cells in the brain to develop new neurons in the brain’s smell center (olfactory bulb).

6. Weight loss
Rambunctious sex burns a minimum of two hundred calories, about the same as running fifteen minutes on a treadmill. British researchers determined that the equivalent of six Big Macs can be worked off by having sex three times a week for a year.

9. Healthier heart
Women who have more sex have higher levels of estrogen, which protects against heart disease.

10. Cure for the common cold
Once-a-week sex produces 30 percent higher levels of immunoglobulin A, which boosts the immune system.

11. Better bladder control
Sex strengthens the pelvic muscles that control the flow of urine.

15. Relief for a stuffy nose
Really. Sex is a natural antihistamine. It can even help combat hay fever and asthma.

17. Boosts immune system
Endorphins stimulate immune-system cells that fight disease.

19. Protection against Alzheimer’s and osteoporosis
Women who have more sex have higher levels of estrogen, which protects against Alzheimer’s and osteoporosis.

Toxic cheap jewelry poisons children

What little kid DOESN'T chew on stuff. Stay away from cheap jewelry!

LOS ANGELES – The country's top product safety regulator warned parents and caretakers Wednesday to take cheap metal jewelry away from children out of concern they could be exposed to toxic heavy metals such as lead and cadmium.

Writing in a blog to be posted Wednesday evening, the chairman of the Consumer Product Safety Commission noted that children who chew, suck on or swallow a bracelet charm or necklace may be endangering their health.

Monsanto GMO corn and organ failure

I can only say EAT ORGANIC!!! Blech. Some other GMO corn I think kills monarch butterflies...scary stuff.

In a study released by the International Journal of Biological Sciences, analyzing the effects of genetically modified foods on mammalian health, researchers found that agricultural giant Monsanto's GM corn is linked to organ damage in rats.
