Study: Blame Winter Baby Mama “at the reduction of life

 

study-winter-mom-and-babyA large body of research suggests that an average winter, babies grow up to be less educated, less intelligent, less healthy and less well paid than those born in spring, summer or autumn. Scientists have blamed the winter ills especially infants, since the time of the age cutoffs for school.

And now, a pair of University of Notre Dame economists have proposed an explanation that could account for half of the difference between winter and newborn babies during the remainder of the year: Ma.

Babies born in winter are more likely to have mothers who are unmarried adolescents who lack a high school diploma, and Daniel Buckles Kasey Hungerman concluded in a National Bureau of Economic Research Working Paper. They based their findings on an analysis of the U.S. birth certificates and census data.

Mothers should not worry about the fate of their children just because they were born in January, February or March, according Hungerman, PhD was born in February. “When you have a child may not matter as much as people thought,” he says. “Who are you, what really matters.”

In other words, he says, having been born to a woman of lower socioeconomic status, not their month of birth, which puts babies winter at a disadvantage.

But why are the women of lower socioeconomic status more likely to give birth in the winter?

Weather could play a role, but not because, as others have hypothesis, mothers of babies in winter are more likely to be sick with colds or the flu, said Buckles.

Consider that the heat is detrimental to sperm, which could explain the salsa spring – summer, nine months later – in births among women with lower socioeconomic status.

The heat may disproportionately affect their fertility because partners are less likely to have air conditioning, said Buckles.

And furthermore, could be the “Dance of the babies’ factor, it is speculated, noting that winter comes nine months after high school proms.

Surveys repeatedly show that winter is the least desirable women in the season to give birth, Buckles and Hungerman write. Perhaps theorize that those who are better educated and wealthier have better control over the dates of births of their children.

Amitabh Chandra, a professor of public policy at Harvard who has previously worked with Buckles, called his study Hungerman “impeccable”.

Although socioeconomic mothers could explain more like 20% of the difference between babies born in the winter and other seasons – 50% did not claim the authors – Chandra said, “… in the social sciences is enormous. “

Hopeful New Kidney Cancer Treatment

kidneyKidney cancer usually does not show symptoms until the disease is spread to other organs. This type of cancer is also often found on the stage are difficult to be cured.
Technical chemotherapy is the latest big show in the hope to extend the age of the patients with advanced cancer stadium. However, this therapy can also be very harmful considering the effects of poison.

In the latest findings on kidney cancer, experts of the University of California Davis, United States, successfully identified a way to impede the recovery mechanism by the genes in cancer cells. This is expected to increase the success of kidney cancer chemotherapy and make it more effective and more can be tolerated.

“Tuesday is famous cancer will be their ability to quickly create copies of themselves. Termutakhir Although the treatment successfully slows the process, the treatment does not tend to heal and may have side effects,” said the leader of the research, Robert Weiss, in which temuannya publicize journal Cancer Biology and Therapy, edition of December.

“We want to find ways to make chemotherapy effective as possible with the lowest dose,” he said.

Working with the latest treatment methods damage the stability of cancer cells in the level of DNA, which reduces their ability to reproduce themselves. The researchers, who know that the p21 genes have an important role in restoring the DNA of cancer cells and exploring the potential benefits for the treatment, trying to identify the order that can disrupt the point.

The team is to test thousands of substances and 12 of them can be found rekombinan binding protein, p21. The pilot shows three additional materials that reduce expression of p21, and impede the ability of kidney cancer cells to repair themselves and make it more responsive to treatment that damage DNA.

To study the future, the research team will focus on three candidates to ensure that the substance of the lowest concentration that may make them still more effective and to optimize the content antikankernya. Research will then test the material with standard treatment in the example of animals before finally tested in humans.

Men are more sensitive to caffeine

men-are-more-sensitiveA large cup of coffee has a greater effect on men than women, research shows. In a study of 668 healthy volunteers, an espresso pepped of men after just 10 minutes. Women also became more alert after drinking, but not both.

University of Barcelona, researchers say that some of this effect may be psychological, because decaffeinated coffee also worked to some extent. Progress in Neuro-psychopharmacology and Biological Psychiatry reports of the work.

The volunteers were asked to drink either a classic espresso coffee contains 100 mg of caffeine or a decaf espresso contains 5 mg of caffeine. Then the researchers looked for changes in surveillance during the following minutes and hours. Both men and women saw an improvement in activity levels after taking the classic espresso and these effects are initiated after only 10 minutes.

Awakening

According to the researchers, 45 minutes is the time to maximum concentration of caffeine to be achieved in the blood, but this will reach half the concentration levels after a few minutes.

And the effect seems to be higher in men. Decaffeinated coffee has a similar but weaker effect and tended to be stronger in women than in men.

Principal investigator Ana Adam said: “Numerous studies have demonstrated the stimulating effect of caffeine, but none of them have studied its effects on consumers in terms of gender.”

Anna Denny of the British Nutrition Foundation, said: “This study offers an interesting insight into how the effects of certain foods and nutrients may differ between men and women.

“The research on gene-nutrient” interactions is advancing rapidly and we are discovering more about how our genetic makeup affects our needs certain foods and nutrients, and how our bodies react to them. In the future this could allow scientists to make dietary recommendations based on our genetic structure, as well as our age and body size. ”

Dr. Paul Euán the British Coffee Association said: “This new scientific study shows interesting differences in the positive effects of caffeine can have on the alert for men and women, an area that has not been investigated much in previous research. We welcome further research to investigate with greater certainty the differences in the stimulatory effects of caffeine that can be tested among groups of women. “
