Gingivae is soft tissue that serves as a biological barrier to cover the oral cavity side of the maxilla and mandible. Recently, the gingivae were identified as containing mesenchymal stem cells (GMSCs). However, it is unknown whether the GMSCs are derived from cranial neural crest cells (CNCC) or the mesoderm.
'Organic' milk has a lower concentration of elements like zinc, iodine and selenium than milk produced by conventional farming methods, due to the absence of mineral substances in the diets of the cows reared.
According to researchers at the University of Santiago de Compostela, animals on organic farms should have their diets supplemented with iodine because it is a very important element for children and pregnant women.
About 5 million children worldwide have been born by IVF since 1978, and 1.4 percent of total births in the U.S. annually and as many as 4.4 percent in western Europe result from the procedure, according to government and industry figures.
Across all types of IVF procedures, compared with spontaneous pregnancies, a study found no increase in the risk of autism, but in one type there was.
Methane has been in water since man has been able to drink water from the ground - but when environmental activists sink their teeth into a fundraising issue, it suddenly becomes a cancer epidemic (nuclear power, along with everything else) and, in the case of hydraulic fracturing - fracking - the Earth deflating and even setting water on fire.
Now, water on fire is hilarious. Pittsburgh, like every other place, has lots of chemicals in its water and most prevalent is the one that makes people ridicule Cleveland. Yet if you ask most people about when the Cuyahoga River in Cleveland was on fire, or why, they won't know. It's just...Cleveland.
Claims from Chen-Yu Zhang's group at China's Nanjing University made international headlines when they reported that, after mice ate lettuce, bits of genetic material from the plants made its way into their bloodstreams intact
- and could turn the animals' own genes off.
Miracle vegetable of the week journalists said it was a triumph for the promise of medicinal food. Scare journalism of the week writers instead worried that genetically modified food might modify consumers in unanticipated ways.
Look for actual science to receive far less attention.
Scholars have linked higher IQ at early school age to weight gain and increased head size in the first month of a baby's life.
The results were determined - as apparently intelligence is - by analyzing data from more than 13,800 children who were born full-term.
The findings in Pediatrics were that babies who put on 40% of their birth weight in the first four weeks had an IQ 1.5 points higher by the time they were six years of age, compared with babies who only put on 15% of their birth weight. Those with the biggest growth in head circumference also had the highest IQs.
Deciding who gets a lung transplant - and thereby who doesn’t - is not easy. Lungs can only be transplanted from people who are organ donors, who are brain dead, and who died in such a way that their organs remain intact. Problem is, there are not enough people marking the “organ donor” box on their driver’s license to give everyone on the transplant list a chance to live.
If you are a patient in the United Kingdom's National Health Service (NHS), try to have surgery on a Monday instead of a Friday, says a paper in the British Medical Journal.
The authors analyzed over four million elective procedures conducted in NHS hospitals in England between 2008 and 2011. They found that 27,582 patients died within 30 days of surgery and the mortality rate was lowest for patients having operations on Monday. Mortality increased for each subsequent day of the week. The odds of death were 44 per cent higher for operations on a Friday than a Monday.
