“Floss for Fertility,” Women Advised (BBC)

Women who want the best chance of having a baby should make sure they floss their teeth regularly, say doctors.

Poor oral health is as bad for fertility as obesity – delaying conception by about two months.

Experts at a fertility meeting in Sweden heard how women with gum disease took over seven months to conceive, compared to the usual five months.

They believe the underlying cause is inflammation.

Unchecked, this can set off a chain of reactions capable of damaging the body’s normal workings…MORE


Surprising Culprits Behind Cell Death from Fat & Sugar Overload (MedicalXpress)

Excess nutrients, such as fat and sugar, don’t just pack on the pounds but can push some cells in the body over the brink. Unable to tolerate this “toxic” environment, these cells commit suicide.

Now, scientists at Washington University School of Medicine in St. Louis have discovered three unexpected players that help a cell overloaded with fat initiate its own demise. They have shown that these molecules leading a cell to self-destruct are not proteins as might be expected, but small strands of RNA, a close chemical cousin to DNA. Since these small nucleolar RNAs play well-known roles in building proteins, the researchers were surprised to implicate them in killing cells.

The research, published July 6 in Cell Metabolism, is the first to link these small RNA molecules to the cellular damage characteristic of common metabolic diseases like diabetes…MORE


Eating Fake Fat Makes You Real Fat, Olestra Study Finds (ABC News)

In a new study released today by Purdue University, researchers found that rats who were fed Olean-containing potato chips as part of a high-fat diet ate more overall and gained more weight than those who were fed a high fat diet and regular, full-fat potato chips.

This counter-intuitive finding shakes the conventional wisdom that substituting lower calorie, lower fat foods for the full-fat versions will help reduce overall caloric intake and encourage weight loss…MORE


Bitter News for Drinkers of Diet Soda (San Antonio Express-News)

Two new studies from San Antonio suggest diet sodas might be a bad idea.

In one study that followed 474 older San Antonians for about a decade, those who drank diet sodas grew bigger bellies compared to those who didn’t, with those drinking the most suffering the biggest increases.

In the other study, artificial sweetener was added to the diets of mice bred to be prone to diabetes. After three months, the animals fed the artificial sweetener had higher blood sugar levels than mice not fed sweetener…MORE


Air Pollution Linked to Learning & Memory Problems, Depression (ScienceDaily)

Long-term exposure to air pollution can lead to physical changes in the brain, as well as learning and memory problems and even depression, new research in mice suggests.

While other studies have shown the damaging effects of polluted air on the heart and lungs, this is one of the first long-term studies to show the negative impact on the brain, said Laura Fonken, lead author of the study and a doctoral student in neuroscience at Ohio State University.

“The results suggest prolonged exposure to polluted air can have visible, negative effects on the brain, which can lead to a variety of health problems,” Fonken said…MORE


UCSF, Stanford Autism Study Shows Surprises (SF Chronicle)

Environmental factors play a more important role in causing autism than previously assumed and, surprisingly, an even larger role than genetics, according to a new study out of UCSF and Stanford that could force a dramatic swing in the focus of research into the developmental disorder.

The study, published in Monday’s issue of the Archives of General Psychiatry, looked at 192 pairs of twins in California and, using a mathematical model, found that genetics account for about 38 percent of the risk of autism, and environmental factors account for about 62 percent…MORE


How Tooth Microbes Aim Straight for the Heart (

Bacteria best known for causing cavities are also able to make their way into heart tissue, causing endocarditis, a dangerous and potentially lethal condition.

Identification of the protein that allows Streptococcus mutans to gain a foothold is reported in the journal Infection and Immunity, and may lead to a screening tool, like a swab of the cheek, or a spit test, to gauge a dental patient’s vulnerability to the condition…MORE
