SACRAMENTO, Calif. - Latinos and Asian Americans are the least likely to have a say in California's politics, during election cycles and year round. That is one of the key findings of a new report by Advancement Project and the School of Public Policy at University of California, Riverside, the first comprehensive assessment in more than a decade of political participation at the ballot box and beyond in California.

Proteins consist of chains of amino acids and in each one it is possible to make out short sequences of amino acids with a discrete function called functional motifs. In some instances these motifs have already been described, in others they are yet to be specified. When a functional motif appears modified, the mutation could influence the development of a disease such as cancer. Verifying the possible changes in a protein is one of the first steps in conducting research into its function.
BARCELONA-LUGANO, 30 June 2016 - Post-operative treatment intensification with chemoradiotherapy does not achieve better outcomes when compared to post-operative chemotherapy in patients with gastric cancer who have already undergone pre-operative chemotherapy, according to phase III data presented at the ESMO 18th World Congress of Gastrointestinal Cancer in Barcelona, Spain.
Parents and society in general shouldn't shift the blame for young people's sexual behavior on what teens supposedly see and read in the media about intimate encounters. Proclaiming a link between such so-called sexy media and the sexual behavior of young people is in fact premature. The media neither contributes to the early initiation of sex among young people, nor to their sexual conduct more generally.
The study shows that the appetite hormone CART not only controls the sensation of satiety, but it also helps increase insulin secretion and decrease glucagon production.
CART (Cocaine and Amphetamine-Regulated Transcript) is a hormone that has mainly been studied in the brain's centre for appetite control.
The research group behind the new study made the previously unknown discovery that CART can also be found in human alpha and beta cells located in the pancreas, and that cells from people with type 2 diabetes contain more CART than cells in people who are healthy.
The nerve cells that transmit pain signals in the body are called nociceptors. When activated they release pro-inflammatory neuropeptides. In order to recognise harmful external influences, nociceptors are equipped with a wide range of receptors. The capsaicin receptor channel, for example, reacts strongly to the spicy substance in chili peppers. Another receptor is sometimes called the mustard oil receptor as it is activated by a substance found in mustard, horseradish and onions.
Bremerhaven/Germany, June 30th, 2016. In a recent study, scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have determined the molecular mechanisms which microalgae apply in order to switch from rapid cell division to growth-arrest during times of acute nutrient deficiency. In laboratory experiments, the scientists have been able to observe that calcifying microalgae in a state of nutrient deficiency initially tweak their metabolism to be more economic and efficient before, out of necessity, they even partially digest themselves.
CAMBRIDGE, MA -- MIT researchers have developed low-cost chemical sensors, made from chemically altered carbon nanotubes, that enable smartphones or other wireless devices to detect trace amounts of toxic gases.
Researchers at the Ruhr-Universität Bochum and the Technische Universität Dortmund have examined how the interactions between solvents and biomolecules change at high pressure. With infrared spectroscopy and computer simulations, they analysed the behaviour of the small molecule TMAO -- short for trimethylamine oxide -- in a pressure range from one bar to ten kilobars. These results could help us understand how organisms have adapted to life in the deep sea on the molecular level.
Researchers at Cardiff University have found that online information about ovarian cancer can cause as much worry as comfort for women at high risk of developing the disease, in a new study published in ecancer.
For women at an increased risk of ovarian cancer but who haven't yet developed the disease, the most effective way to manage their risk is to surgically remove their fallopian tubes and ovaries.
Biofilms are communities of bacteria that adhere to a surface and are nearly impossible to eradicate when they are pathogenic, or disease-causing. Fortunately, a discovery from the laboratories of Lauren Bakaletz, PhD, and Steven Goodman, PhD, in The Research Institute at Nationwide Children's Hospital, provides strong evidence that an innovative therapeutic approach may be effective in the resolution of bacterial biofilm diseases.
An emerging field, known as implementation science, may help reduce the nearly 150,000 instances of mother-to-child HIV transmissions that occur annually around the world, mostly in developing countries. A team of scientists and program managers, led by the National Institutes of Health, has been studying a variety of implementation science approaches to prevent mother-to-child transmission and has published the results in a 16-article open-access supplement to the Journal of Acquired Immune Deficiency Syndromes.
A quiet transformation has been brewing in medicine, as large-scale DNA results become increasingly available to patients and healthcare providers. Amid a cascade of data, physicians, counselors and families are sorting out how to better understand and use this information in making health care decisions.
National experts who have gathered in Clinical Genetics Think Tank meetings at two large pediatric hospitals recently issued their first recommendations for integrating genomics into clinical practice.
- New insight into the most common genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia
- Novel function uncovered for the C9orf72 protein that is linked to amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD)
- Groundbreaking research could pave the way to for potential future drug development
In the late 1980s, researchers across the United States began reporting a link between discrimination against African Americans and poor cardiovascular health within the African American population. Eventually, the scope of these studies broadened, uncovering a connection between discrimination and other health disparities among minority groups.
Now, researchers at the University of Iowa have found another negative health outcome linked to discrimination: alcohol abuse.
