Fruit flies too get kidney stones

Research on kidney stones in fruit flies may hold the key to developing a treatment that could someday stop the formation of kidney stones in humans, a team from Mayo Clinic and the University of Glasgow found.

Testosterone may play a role in treatment of triple negative breast cancer

Could blocking a testosterone receptor lead to a new way to treat an aggressive form of breast cancer? That's a question researchers at Mayo Clinic in Arizona and the Translational Genomics Research Institute (TGen) are exploring. Preliminary results of a Mayo Clinic - TGen collaborative study shows the testosterone receptor may be a potential target to attack in treating triple negative breast cancer (TNBC).

Fraunhofer FIT software rapidly analyzes complex biological processes

At Analytica 2012, Fraunhofer FIT presents software that supports the search for new active pharmaceutical ingredients of cancer drugs. Through a high degree of parallelization, the software can analyze complex biological processes very fast, even with large amounts of data.

Deficiency of Mitofusin 2 protein leads to insulin resistance, glucose intolerance

The study shows that the lack of Mitofusin 2 in mice produces insulin resistance and glucose intolerance, the main causes of diabetes.

Multiresistant bacteria withstand wastewater treatment processes

Large quantities of antibiotic-resistant bacteria enter the environment via municipal - and especially hospital - wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous - multiresistant - strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

Mendelian randomization not the 'Holy Grail' in evaluating alcohol intake with cognitive function

Many observational cohort studies have shown that moderate alcohol use is associated with better cognitive function. However, since such studies are vulnerable to residual confounding by other lifestyle and physiologic factors, the authors conducted a Mendelian randomization study, using aldehyde dehydrogenase 2 (ALDH2) genotype (AA, GA, or GG) as an instrumental variable in 2-stage least squares analysis.

Genetic marker identifies tumors unable to repair DNA damage by platinum agents

Scientists from Brigham and Women's Hospital and Dana-Farber Cancer Institute and their colleagues have found a genetic marker that predicts which aggressive "triple negative" breast cancers and certain ovarian cancers will likely respond to platinum-based chemotherapies.

Treatment with aromatase inhibitors enables some women to have lumpectomy

Preoperative treatment with aromatase inhibitors increases the likelihood that postmenopausal women with estrogen receptor-positive breast cancer will be able to have breast-conserving surgery rather than a mastectomy, according to the results of a national clinical trial presented today at the Society of Surgical Oncology annual meeting in Orlando, Fla.

Max Planck researchers obtain somatic stem cells from fully differentiated somatic cells

Breaking new ground, scientists at the Max Planck Institute for Molecular Biomedicine in M-nster, Germany, have succeeded in obtaining somatic stem cells from fully differentiated somatic cells. Stem cell researcher Hans Sch-ler and his team took skin cells from mice and, using a unique combination of growth factors while ensuring appropriate culturing conditions, have managed to induce the cells' differentiation into neuronal somatic stem cells.

Obese children with PNPLA3 and GCKR genetic variants more susceptible to fatty liver disease

New research found the genetic variant Patatin-like phospholipase domain containing protein-3 (PNPLA3) acting in conjunction with the glucokinase regulatory protein (GCKR) is associated with increased susceptibility to fatty liver disease in obese children.

Uppsala University researchers identify promising biomarkers for ASD

An important step towards developing a rapid, inexpensive diagnostic method for autism has been take by Uppsala University, among other universities. Through advanced mass spectrometry the researchers managed to capture promising biomarkers from a tiny blood sample.

Women with low serum adiponectin levels more likely to develop asthma

Low serum adiponectin levels predict an increased future risk for developing asthma in middle-aged women, particularly among smokers, according to a new study.

UC Riverside to study molecular basis of hormonal regulation of mosquito reproduction

Female mosquitoes require energy for their egg development, which they acquire from vertebrate blood. But by sucking on blood, they become vectors of numerous disease pathogens of human and domestic animals. If the mechanisms that govern their egg production are better understood, novel approaches to controlling the reproduction and population of mosquitoes can be devised.

Immediate skull reconstruction aggravates brain damage in TBI model

Immediate skull reconstruction following trauma that penetrates or creates an indentation in the skull can aggravate brain damage inflicted by the initial injury, a study by a University of South Florida research team reports.

Scripps scientists generate synthetic memory trace

Scripps Research Institute scientists and their colleagues have successfully harnessed neurons in mouse brains, allowing them to at least partially control a specific memory. Though just an initial step, the researchers hope such work will eventually lead to better understanding of how memories form in the brain, and possibly even to ways to weaken harmful thoughts for those with conditions such as schizophrenia and post traumatic stress disorder.

Prenatal PAH exposure can lead to behavioral problems in children

Mothers' exposure during pregnancy to a class of air pollutants called polycyclic aromatic hydrocarbons (PAH) can lead to behavioral problems in their children.

TAS2R38 and CD36 gene may play a role in fat perception

While high-fat foods are thought to be of universal appeal, there is actually a lot of variation in the extent to which people like and consume fat. A new study in the March issue of the Journal of Food Science, published by the Institute of Food Technologists, reported that two specific genes, may play a role in some people's ability to taste and enjoy dietary fat.

Researchers identify corin enzyme linked with pre-eclampsia

Researchers have identified an enzyme linked to pregnancy-induced hypertension - also known as pre-eclampsia - a pregnancy complication characterized by high blood pressure and swelling due to fluid retention. The findings could be used to better screen for - and treat - this condition.

Scientists artificially derive brain stem cells from connective tissue of mice

These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells.

Blocking PFKFB4 enzyme could prevent growth of prostate cancer cells

Cancer Research UK scientists have discovered how blocking a key enzyme, which helps convert glucose into energy, could provide a new way to kill prostate cancer cells, according to a study published in the journal Cancer Discovery.
