The dominant antibody type present in the blood of transplant recipients may indicate their likelihood of experiencing organ rejection, according to a study which may help doctors identify patients who need aggressive treatments to safeguard the health of their new organ.
Transplant recipients who receive a kidney, heart, or lung often develop an immune response to the foreign tissue in the form of antibodies referred as donor-specific HLA antibodies. Some patients may already have these antibodies before their transplant because they have been exposed to blood products or previous transplants. Although the presence of donor-specific HLA antibodies in a recipient is usually not a good sign, not all patients who have them experience a poor outcome.
Women are more likely than men to initiate divorces, but not to end non-marital relationships, according to Michael Rosenfeld, an associate professor of sociology at Stanford University.
Rosenfeld's analysis relies on survey data from the 2009-2015 waves of the nationally representative How Couples Meet and Stay Together survey. He considers 2,262 adults, ages 19 to 94, who had opposite sex partners in 2009. By 2015, 371 of these people had broken up or gotten divorced.
As the use of e-cigarettes has risen dramatically in the United States in recent years, so have calls to poison centers about them, yet most parents are unaware of potential dangers.
The devices are used like cigarettes but instead of tobacco, they vaporize a liquid mixture of nicotine, glycerin and glycol ethers. If ingested, a teaspoon of this "e-liquid" can be lethal to a child, and smaller amounts can cause nausea and vomiting that may necessitate a trip to the emergency room. In a few cases, exposure to skin has also sickened children.
Tomato lovers rejoice: Adding or rearranging a few simple steps in commercial processing could dramatically improve the flavor of this popular fruit sold in the grocery store, according to researchers.
"Ideally, tomatoes should be picked ripe and then sold immediately, as they are at farm stands," says Jinhe Bai, Ph.D. But this isn't always possible for commercially sold tomatoes, which are often stored and then shipped over long distances.
To prevent tomatoes from becoming too ripe before they reach the store, growers pick them when they are still green. Packers then use a gas called ethylene to trigger fruit ripening, and after that the tomatoes are stored and shipped at low temperatures.
The world’s governments are preparing to finalize the Sustainable Development Goals at the United Nations in September 2015. It is set to be a major international event, and the goals will be ushered in with tremendous fanfare; they are widely regarded as a historic step toward building a better world, and toward eradicating poverty and hunger from the face of the Earth once and for all.-->
As part of a periodic review, the National Health and Medical Research Council (NHMRC) is calling for public submissions on its draft guidelines on the use of assisted reproductive technology in clinical practice and research. This, in lay terms, is the practice of in vitro fertiliszation (IVF).
Producing guidelines to advise the community on ethical issues relating to health is one of the NHMRC’s many tasks. Revisions aim to reflect changes in technology and social attitudes and are based on advice from the Australian Health Ethics Committee (AHEC), which I chair.
Shorter mothers have shorter pregnancies, smaller babies, and higher risk for a preterm birth. New research has found that a mother's height directly influences her risk for preterm birth.
Investigators at the March of Dimes Prematurity Research Center Ohio Collaborative looked at 3,485 Nordic women and their babies, and found that maternal height, which is determined by genetic factors, helped shape the fetal environment, influencing the length of pregnancy and frequency of prematurity. In contrast, birth length and birth weight are mainly influenced by transmitted genes. Preterm birth is the number one killer of newborns in the United States and serious gaps exist between racial and ethnic groups.
A recalculation of the dates at which boulders were uncovered by melting glaciers at the end of the last Ice Age has conclusively shown that the glacial retreat was due to rising levels of carbon dioxide and other greenhouse gases, as opposed to other types of forces.
Carbon dioxide levels are now significantly higher than they were at that time, as a result of the Industrial Revolution and other human activities since then. Because of that, the study confirms predictions of future glacial retreat, and that most of the world's glaciers may disappear in the next few centuries.
As is typical of our time, over the past few months, many newscasters have used the words apocalypse or apocalyptic to evoke the negative implications of events as diverse as the threat of Grexit, music streaming wars, an asteroid threat, the American housing market, the migrant cri-->
The explosion in coffee consumption in the past two decades has generally not benefited farmers of coffee beans in poorer nations along the equator, it has mostly just helped corporations, including those marketing "fair trade" as some sort of ethical improvement..
Do you want a better sex life and a better relationship to go with it? Sociologists say surveys show that if men take up more of the child-care duties, splitting them equally with their female partners, heterosexual couples have more satisfaction with their relationships and their sex lives, according to new research by Georgia State University sociologists.
Daniel L. Carlson, along with graduate students Sarah Hanson and Andrea Fitzroy, all of Georgia State University, used data from more than 900 heterosexual couples' responses in the 2006 Marital Relationship Study (MARS).
They found that when women were responsible for most or all of the child care, both parties reported both the lowest quality relationships and sex lives.
Does watching the news make you lose faith in a higher purpose? Does taking out an army of terrorists alone without so much as a scratch make you feel like you must have a divine gift? An analysis of cellphone data shows that spiritual awareness does vary based on activity, rather than being constant, according to sociologists at the American Sociological Association meeting who say that people had the highest levels of spiritual awareness in the morning and while engaged in activities such as praying, worship, and meditation. Spiritual awareness also was high when people listened to music, read, or exercised. It was low while people were doing work-related activities or playing video games.
Regular consumption of caffeinated coffee may help prevent the return of colon cancer after treatment and improve the chances of a cure, according to a new study.
The patients, all of them treated with surgery and chemotherapy for stage III colon cancer, had the greatest benefit from consuming four or more cups of coffee a day (about 460 milligrams of caffeine), according to the study. These patients were 42 percent less likely to have their cancer return than non-coffee drinkers, and were 33 percent less likely to die from cancer or any other cause.
In a dramatic 2013 cover story, Time warned of “A World Without Bees,” subtitled “The price we’ll pay if we don’t figure out what’s killing the honeybee.” Its author argued that the class of agricultural pesticides know as neonicotinoids was killing the honeybee and that the planet would starve unless we banned these chemicals immediately. He said this because “1 in every 3 mouthfuls you’ll eat today,” depends on bee pollination. In short: no bees, no food.-->
It has been almost a century since scientists at Eli Lilly figured out how to make large quantities of pure insulin. This historical discovery made it possible for the first time to save the lives of diabetics (mostly children). But now, we are witnessing another breakthrough.
Although perhaps not as dramatic as the development of insulin, for the first time a hypoglycemic drug has been found to increase life expectancy.-->
