Breast cancer rates are on the rise among pregnant waomen because women are waiting longer to have children.

Breast cancer rates among pregnant women are on the increase because would-be parents are waiting longer to have children, an expert has warned.  The diagnosis of the disease in expectant mothers leads to a terrible dilemma as the treatment can be devastating for the unborn child.

Modeling Autism in a Lab Dish…

A striking resemblance to Jim Carrey… Or is it?

A collaborative effort between researchers at the Salk Institute for Biological Studies and the University of California, San Diego, successfully used human induced pluripotent stem (iPS) cells derived from patients with Rett syndrome to replicate autism in the lab and study the molecular pathogenesis of the disease.

“The Sickle Cell Gene” Supports ‘Malaria Hypothesis”

“Malaria No More” plans on destroying all malaria by 2015!

At a global scale, the sickle cell gene is most commonly found in areas with historically high levels of malaria, adding geographical support to the hypothesis that the gene, while potentially deadly, avoids disappearing through natural selection by providing protection against malaria.

Bright Stars of the Brain Regulate Breathing

This image of brainstem astrocytes was taken using a confocal microscope.

Astrocytes — brain cells named after their characteristic star-shape and previously thought to act only as the ‘glue’ between neurons, have a central role in the regulation of breathing, according to scientists.

Baby Brain Growth Mirrors Changes from Apes to Humans

Areas of expansion in the human cortex during infancy and childhood, top, closely match areas of change in the human brain when compared to the brains of apes and monkeys. Yellow areas expanded the most, followed by orange, red, blue and light blue areas.

A study undertaken to help scientists concerned with abnormal brain development in premature babies has serendipitously revealed evolution’s imprint on the human brain.

Obesity is Becoming an Increasing Burden in the Maternity Ward

obese and pregnant

One in five women are obese when they become pregnant.

As Americans have grown fatter over the last generation, inviting more heart disease, diabetes and premature deaths, all that extra weight has also become a burden in the maternity ward, where babies take their first breath of life. 

About one in five women are obese when they become pregnant, meaning they have a body mass index of at least 30, as would a 5-foot-5 woman weighing 180 pounds, according to researchers with the federal Centers for Disease Control and Prevention. And medical evidence suggests that obesity might be contributing to record-high rates of Caesarean sections and leading to more birth defects and deaths for mothers and babies.

Children With Autism Show Slower Pupil Responses, Study Finds

The Human eye

Autism affects an estimated 1 in 150 children today, making it more common than childhood cancer, juvenile diabetes and pediatric AIDS combined. Despite its widespread effect, autism is not well understood and there are no objective medical tests to diagnose it. Recently, University of Missouri researchers have developed a pupil response test that is 92.5 percent accurate in separating children with autism from those with typical development. In the study, MU scientists found that children with autism have slower pupil responses to light change.

Disinfectants Used To Purify Water Create Toxic By-Products

Disinfectants Used To Purify Water Create Toxic By-Products

 

Although perhaps the greatest public health achievement of the 20th century was the disinfection of water, a recent study now shows that the chemicals used to purify the water we drink and use in swimming pools react with organic material in the water yielding toxic consequences.

Transplanted Stem Cells Undo Birth Defects

Transplanted Stem Cells Undo Birth Defects 

 Neural stem cells, tagged green with a fluorescent dye, have been transplanted among the brain cells (red) of a mouse born with brain damage after its mother was given heroin during pregnancy.

By injecting stem cells directly into the brain, scientists have successfully reversed neural birth defects in mice whose mothers were given heroin during pregnancy. Even though most of the transplanted cells did not survive, they induced the brain’s own cells to carry out extensive repairs.
