Researchers generate kidney tubular cells from stem cells Posted: 19 Dec 2013 04:59 PM PST Investigators have discovered a cocktail of chemicals which, when added to stem cells in a precise order, turns on genes found in kidney cells in the same order that they turn on during embryonic kidney development. The kidney cells continued to behave like kidney cells when transplanted into adult or embryonic mouse kidneys.

Bullying in academia more prevalent than thought Posted: 19 Dec 2013 01:29 PM PST Bullying isn't only a problem that occurs in schools or online among young people. It can happen anywhere to anyone, and a nursing scholar is shedding some light on how it is becoming increasingly common in academia.

Black-white infant mortality gap: Large, persistent, unpredictable Posted: 19 Dec 2013 01:29 PM PST The unobservable factors that underpin the infant mortality gap between blacks and whites have persisted for more than 20 years and now appear to play a larger role than the observable factors, according to a new study.

New way to map important drug targets Posted: 19 Dec 2013 11:21 AM PST Researchers have used new techniques and one of the brightest X-ray sources on the planet to map the 3-D structure of an important cellular gatekeeper in a more natural state than possible before.

With sinus study, harmless members of microbiome spark immune reaction Posted: 19 Dec 2013 10:44 AM PST Researchers have found evidence that some chronic sinus issues may be the result of inflammation.

Nutrition influences metabolism through circadian rhythms, study finds Posted: 19 Dec 2013 10:44 AM PST A high-fat diet affects the molecular mechanism controlling the internal body clock that regulates metabolic functions in the liver, scientists have found. Disruption of these circadian rhythms may contribute to metabolic distress ailments, such as diabetes, obesity and high blood pressure.

Controlling parasitic worms with genetic selection Posted: 19 Dec 2013 10:12 AM PST Helminths are gastrointestinal parasitic worms that have become a major concern and source of economic loss for sheep producers around the world. A new article reviews current research into a promising alternative to control the disease.

Brain connections may explain why girls mature faster Posted: 19 Dec 2013 10:11 AM PST Scientists have discovered that as the brain re-organizes connections throughout our life, the process begins earlier in girls which may explain why they mature faster during the teenage years.

Congenital heart disease causes hypoglycaemia Posted: 19 Dec 2013 10:11 AM PST In a new study, scientists document a connection between congenital arrhythmia and the bodies' ability to handle sugar. The results can be of vital importance for patients with the disease and for the future treatment of diabetes.

Healthier happy meals Posted: 19 Dec 2013 10:10 AM PST What would happen if a fast-food restaurant reduces the calories in a children's meal by 104 calories, mainly by decreasing the portion size of French fries? Would children compensate by choosing a more calorie dense entrée or beverage? Researchers analyzed transaction data from 30 representative McDonald's restaurants to answer that question.

Chewing gum is often culprit for migraine headaches in teens Posted: 19 Dec 2013 10:09 AM PST A researcher has found that gum-chewing teenagers, and younger children as well, are giving themselves headaches with this habit. These findings could help treat countless cases of migraine and tension headaches in adolescents without the need for additional testing or medication.

Monthly appointments with pharmacists improve medication adherence Posted: 19 Dec 2013 10:09 AM PST Patients are more likely to take chronic medications when they meet monthly with pharmacists to coordinate medication schedules and treatments, according to a study.

A new -- and reversible -- cause of aging: A naturally produced compound rewinds aspects of age-related demise in mice Posted: 19 Dec 2013 10:07 AM PST Researchers have discovered a cause of aging in mammals involving a series of molecular events that disables communication between the nucleus and mitochondria. By administering a molecule naturally produced by the human body, the communication network was restored in older mice. Subsequent tissue samples showed biological hallmarks comparable to much younger animals.

First cancer operation room with navigator is created Posted: 19 Dec 2013 09:30 AM PST A team of researchers have started the first cancer operation room with a navigator. This image-guided system will allow for increased intraoperative radiotherapy safety.

Anti-epilepsy drugs can cause inflammation Posted: 19 Dec 2013 05:27 AM PST Physicians have been investigating if established anti-epilepsy drugs have anti-inflammatory or pro-inflammatory properties – an effect for which these pharmaceutical agents are not usually tested. One of the substances tested caused stronger inflammations, while another one inhibited them. As inflammatory reactions in the brain may be the underlying cause for epileptic disorders, it is vital to take the trigger for the disorder under consideration when selecting drugs for treatment, as the researchers concluded.

Stress reaction gene linked to death, heart attacks Posted: 19 Dec 2013 05:25 AM PST A genetic trait known to make some people especially sensitive to stress also appears to be responsible for a 38 percent increased risk of heart attack or death in patients with heart disease, scientists report.

With surgical robot, similar outcomes higher cost Posted: 18 Dec 2013 02:07 PM PST In a study of national data on colon surgery, researchers found that while patients who undergo either minimally invasive laparoscopic surgery or the high-tech robotic approach have similar outcomes, robotic surgery is significantly more expensive.

H1N1-triggered narcolepsy may stem from 'molecular mimicry' Posted: 18 Dec 2013 11:37 AM PST In genetically susceptible people, narcolepsy can sometimes be triggered by a similarity between a region of a protein called hypocretin and a portion of a protein from the pandemic H1N1 virus, according to a new study.

Newly identified immune receptor may activate B cells in autoimmunity Posted: 18 Dec 2013 11:37 AM PST A newly identified immune protein influences each person's response to vaccines and risk for autoimmune diseases like lupus and multiple sclerosis. The protein, called a receptor and part of signaling pathways, also provides a new target for personalized therapies for patients with autoimmune diseases.

Researchers identify genetic marker of resistance to key malaria drug Posted: 18 Dec 2013 10:37 AM PST An international team of researchers has discovered a way to identify, at a molecular level, malaria-causing Plasmodium falciparum parasites that are resistant to artemisinin, the key drug for treating this disease.

Immune avoidance mechanism could lead to treatments for deadly mosquito-borne viruses Posted: 18 Dec 2013 10:36 AM PST A mosquito-borne virus that kills about half of the people it infects uses a never-before-documented mechanism to "hijack" one of the cellular regulatory systems of its hosts to suppress immunity, according scientists. The discovery could aid in the development of vaccines and treatments for eastern equine encephalitis virus.

Obese children have higher stress hormone levels than normal weight peers Posted: 18 Dec 2013 10:35 AM PST Obese children naturally produce higher levels of a key stress hormone than their normal weight peers, according to new research.

Diet rich in tomatoes may lower breast cancer risk Posted: 18 Dec 2013 10:35 AM PST A tomato-rich diet may help protect at-risk postmenopausal women from breast cancer, according to new research.

Brain area attacked by Alzheimer's links learning, rewards Posted: 18 Dec 2013 10:02 AM PST One of the first areas of the brain to be attacked by Alzheimer's disease, the posterior cingulate cortex, or PCC, has been found to step in during a cognitive challenge to improve the brain's performance. This small study in monkeys establishes a role for the PCC in learning and its connection to the brain's reward system.

Improving pollen forecasting for better quality of life for allergy sufferers Posted: 18 Dec 2013 10:02 AM PST New measurements on the properties and spread of airborne pollen to improve the forecasting of this natural allergen, which affects human health as well as the Earth's temperature, have been published in a new international study.
