As treatments for HIV/AIDS improve and patients are living longer, the distribution of cancers in this population has undergone a dramatic shift in the United States. While cases of the types of cancer that have been associated with AIDS progression have decreased, cases of other types of cancer are on the rise. These results, reported by scientists from the National Cancer Institute (NCI), part of the National Institutes of Health, and the Centers for Disease Control and Prevention, were published online April 11, 2011, in the Journal of the National Cancer Institute. The ...

Scientists at the University of California, San Francisco have pinpointed a reason older adults have a harder time multitasking than younger adults: they have more difficulty switching between tasks at the level of brain networks. Juggling multiple tasks requires short-term, or "working," memory – the capacity to hold and manipulate information in the mind for a period of time. Working memory is the basis of all mental operations, from learning a friend's telephone number, and then entering it into a smart phone, to following the train of a conversation, to conducting ...

Combining the chronic kidney disease markers of creatinine-based estimated glomerular filtration rate and urine albumin-to-creatinine ratio with the biomarker cystatin C was associated with improved prediction of end-stage kidney disease and all-cause death, according to a study that will appear in the April 20 issue of JAMA. The study is being published early online to coincide with its presentation at the World Congress of Nephrology. Chronic kidney disease (CKD) is currently defined as certain levels of creatinine-based estimated glomerular filtration rate (GFR) or ...

A prediction model that included data on measures of several routinely obtained laboratory tests including blood levels of calcium, phosphate and albumin accurately predicted the short-term risk of kidney failure for patients with moderate to severe chronic kidney disease, according to a study that will appear in the April 20 issue of JAMA. The study is being published early online to coincide with its presentation at the World Congress of Nephrology. "An estimated 23 million people in the United States (11.5 percent of the adult population) have chronic kidney disease ...

In a famous experiment first performed more than 220 years ago, Italian physician Luigi Galvani discovered that the muscles of a frog's leg twitch when an electric voltage is applied. An international group of scientists from Italy, the UK and France has now brought this textbook classic into the era of nanoscience. They used a powerful new synchrotron X-ray technique to observe for the first time at the molecular scale how muscle proteins change form and structure inside an intact and contracting muscle cell. The results are published in the 11 April 2011 issue of the ...

The new model, to be named the 'Stealth', will be 15 Kg lighter, more rigid and able to handle more aggressive riding due to its hull construction. The idea to produce the Carbon fibre model was the brainchild of Chris Kanyaro. The initial concept being to lighten the overall weight of the current Sports Model. The new Stealth model will be much lighter, meaning more Horse Power, we expect an extra 5 - 10 K / Hr, better fuel consumption and ride. We are still in the early production phase but are due to have our prototype ready for testing in the coming month. Launch ...

The meaning of the standard fecal coliform test used to monitor water quality has been called into question by a new study that identified sources of Escherichia coli bacteria that might not indicate an environmental hazard. Fecal pollution of surface waters is measured by the concentration of E. coli bacteria in the water because E. coli is believed to live only in the intestines and waste of humans and other warm-blooded animals, and quickly die outside its host. The presence of E. coli in water also serves as a marker for other potentially more harmful organisms that ...

The number of cancers and the types of cancers among people living with AIDS in the U.S. have changed dramatically during the 15-year period from 1991-2005, according to an article published online April 11th in the Journal of the National Cancer Institute. It is known that HIV-infected patients face an increased risk of Kaposi sarcoma, non-Hodgkin lymphoma, and cervical cancer--the AIDS-defining cancers--and that the incidence of these cancers dropped when highly active anti-retroviral therapy (HAART) became available in the mid-1990s. People living with HIV and AIDS ...

Will only a few select people make it to heaven? Will billions of people spend eternity in hell? Many people are angry with God for allowing evil and suffering to exist in this world, and yet they are also angry with the idea of God as judge. You can't have it both ways, says Trevin Wax, associate pastor of First Baptist Church in Shelbyville, Tenn., and author of the new book Counterfeit Gospels: Rediscovering the Good News in a World of False Hope. "If you expect God to do something about the evil in this world, then you want God to judge," Wax explains. The ...

Hair grooming practices, such as braids and weaves, as well as inflammation in the form of bacterial infection, may be contributing to the development of scarring hair loss in African American women, according to a report posted online today that will appear in the August print issue of Archives of Dermatology, one of the JAMA/Archives journals. "Central centrifugal cicatricial alopecia (CCCA) is a term coined by the North American Hair Research Society to describe a scarring hair loss, centered on the vertex of the scalp, that spreads peripherally," the authors write ...

The act of making a recommendation appears to change the way physicians think regarding medical choices, and they often make different choices for themselves than what they recommend to patients, according to a survey study published in the April 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. "Patients facing difficult decisions often ask physicians for recommendations," the authors write as background information in the study. "However, little is known regarding the ways that physicians' decisions are influenced by the act of making a recommendation." Peter ...

CHAMPAIGN, Ill. — Most people have trouble telling them apart, but bumble bees, honey bees, stingless bees and solitary bees have home lives that are as different from one another as a monarch's palace is from a hippie commune or a hermit's cabin in the woods. A new study of these bees offers a first look at the genetic underpinnings of their differences in lifestyle. The study focuses on the evolution of "eusociality," a system of collective living in which most members of a female-centric colony forego their reproductive rights and instead devote themselves to specialized ...

Angiogenesis, the development of new blood vessels, is required during embryonic development and wound healing, as well as during disease processes such as tumor growth. The signals that direct angiogensis are incompletely understood, but could represent novel targets for the development of therapies that promote or inhibit this process. In this paper, Young-Guen Kwon and colleagues, of Yonsei University in Seoul, Korea, investigated the role of two related proteins- DKK1 and DKK2- in angiogenesis. These proteins are known to have similar functions in inhibiting a particular ...

PASADENA, Calif.—When black holes slam into each other, the surrounding space and time surge and undulate like a heaving sea during a storm. This warping of space and time is so complicated that physicists haven't been able to understand the details of what goes on—until now. "We've found ways to visualize warped space-time like never before," says Kip Thorne, Feynman Professor of Theoretical Physics, Emeritus, at the California Institute of Technology (Caltech). By combining theory with computer simulations, Thorne and his colleagues at Caltech, Cornell University, ...

Denver, CO., April 11, 2011 – Research to be presented this week at The Federation of American Societies for Experimental Biology (FASEB) Conference in Washington, D.C., demonstrates that consumption of white potatoes (non-fried) by children does not displace other vegetables from children's meals. In fact, meals that contain white potatoes contain more servings of other vegetables, and are significantly higher in potassium, fiber and vitamin C. Both potassium and fiber were identified as nutrients of concern in the 2010 Dietary Guidelines, released February 2011. "Potatoes ...

Washington, D.C., April 11, 2011 – In a first-of-its-kind study with nuts, randomized controlled-feeding research conducted by the Agricultural Research Service (ARS) of the United States Department of Agriculture (USDA) found that fat in pistachios may not be completely absorbed by the body. The findings indicate that pistachios may actually contain fewer calories per serving than originally thought – further validating pistachios as one of the lowest calorie nuts with 160 calories per 30 gram serving (approximately 1 ounce). The study was presented today at the Experimental ...
