Nature-engineered nanomotors could be used in targeted drug delivery

In the quest to shrink motors so they can maneuver in tiny spaces like inside and between human cells, scientists have taken inspiration from millions of years of plant evolution and incorporated, for the first time, corkscrew structures from plants into a new kind of helical "microswimmer."

Boston College researchers combine two catalytic reactions to produce highly reactive compounds

Boston College chemists have developed a new chemical synthesis methodology that converts chemicals known as alpha-olefins into new organic compounds.

Study finds milk serves as protective carrier of bioactive molecules

Polyphenols found in tea manifest anti-cancer effects but their use is limited by poor bioavailability and disagreeable taste. A new study in the Journal of Dairy Science- finds that when epigallocatechin gallate (EGCG), the major extractable polyphenol in green tea and the most biologically active, when diluted in skim milk or other milk complexes remains bioactive and continues to reduce colon cancer cell proliferation in culture at concentrations higher than 0.03 mg of EGCG/mL.

Sugar-based gelators may provide alternatives to trans fats linked to obesity, heart disease, diabetes

Researchers at The City College of New York have reported the successful transformation of vegetable oils to a semisolid form using low-calorie sugars as a structuring agent.

Study supports mounting evidence that inflammation may be the cause of chronic rhinosinusitis

Saint Louis University researchers have analyzed the microbiomes of people with chronic rhinosinusitis and healthy volunteers and found evidence that some chronic sinus issues may be the result of inflammation triggered by an immune response to otherwise harmless microorganisms in the sinus membranes.

UC Irvine scientists find that reprogramming of liver 'clock' may contribute to metabolic disorders

A high-fat diet affects the molecular mechanism controlling the internal body clock that regulates metabolic functions in the liver, UC Irvine scientists have found. Disruption of these circadian rhythms may contribute to metabolic distress ailments, such as diabetes, obesity and high blood pressure.

Researchers develop diagnostic nanomachine to screen diseases that have genetic basis

As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology. The results of this research is published this month in the journal ACS Nano.

Researchers reveal how metabolic system breaks down in obesity

Researchers at University of Michigan have illuminated an aspect of how the metabolic system breaks down in obesity. The findings provide additional evidence that a drug entering clinical trials at the university could reverse obesity, Type 2 diabetes and fatty liver disease in humans.

Study: Standard treatment approaches yield modest to large improvement in TMD patients

empromandibular pain disorders (TMDs) are characterized by a dysfunction of the TMD joint and cause orofacial pain, masticatory dysfunction or both.

Researchers develop oral vaccine against Helicobacter pylori

Researchers from Southern Medical University in Guangdong, Guangzhou, China, have developed an oral vaccine against Helicobacter pylori, the bacteria responsible for peptic ulcers and some forms of gastric cancer, and have successfully tested it in mice. The research is published ahead of print in the journal Clinical and Vaccine Immunology.

Researchers map cell's complex genetic interactions to fix UV damaged DNA

Researchers at the University of California, San Diego School of Medicine, with colleagues in The Netherlands and United Kingdom, have produced the first map detailing the network of genetic interactions underlying the cellular response to ultraviolet (UV) radiation.

Two GW professors named 2013 Fellows of the National Academy of Inventors

Ferid Murad and Akos Vertes-two of George Washington University's scientific pioneers-are among the 143 innovators who have been named 2013 Fellows of the National Academy of Inventors.

Co-culture with mesenchymal stem cells results in improved viability, function of human hepatocytes

Hepatocyte transplantation is becoming an accepted therapy for acute liver failure, either for liver regeneration or as a bridge to liver transplantation. However, maintaining the viability and functional aspects of hepatocytes has been a concern even with successful freezing.

Researchers investigate several non-invasive methods for measuring intracranial pressure

Do you ever turn your world upside down by standing on your head? After a few minutes you might feel some pressure in your face and around your skull. This is because headstands invert the body's blood flow, pushing more blood toward your head.

Regenerative medicine may offer ways to banish baldness

Regenerative medicine may offer ways to banish baldness that don't involve toupees. The lab of USC scientist Krzysztof Kobielak, MD, PhD has published a trio of papers in the journals Stem Cells and the Proceedings of the National Academy of Sciences (PNAS) that describe some of the factors that determine when hair grows, when it stops growing and when it falls out.

Study reveals why people are predisposed to cardiovascular disease and death

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 at Duke Medicine report.

Cells grown in ISS could help patients recover from stroke, says Mayo Clinic researcher

Abba Zubair, M.D., Ph.D, believes that cells grown in the International Space Station could help patients recover from a stroke, and that it may even be possible to generate human tissues and organs in space. He just needs a chance to demonstrate the possibility.

New RUB project to unravel role of enzyme Parkin in promoting neuronal survival

Cell biologists at the Ruhr-Universit-t Bochum have launched a new project to unravel the role of the enzyme Parkin in promoting neuronal survival. The team of Prof Dr Konstanze F. Winklhofer from the Institute of Physiological Chemistry, Department of Molecular Cell Biology, is looking for new therapeutic options to treat Parkinson's disease. The Michael J. Fox Foundation finances this research project with 125,000 US Dollars.

MSCs isolated from MS patients have decreased suppressive function

Multiple sclerosis, an inflammatory autoimmune disease affecting more than one million people worldwide, is caused by an immune reaction to myelin proteins, the proteins that help form the myelin insulating substance around nerves. Demyelination and MS are a consequence of this immune reaction. Bone marrow mesenchymal stem cells have been considered as an important source for cell therapy for autoimmune diseases such as MS because of their immunosuppressive properties.

Aerobic glycolysis is a cause of malignancy, show Berkeley Lab researchers

Metabolism was lost in the shadows of cancer research for decades but has recently been reclaiming some of the spotlight. Now, Mina Bissell, Distinguished Scientist with Berkeley Lab's Life Sciences Division and a leading authority on breast cancer, has shown that aerobic glycolysis - glucose metabolism in the presence of oxygen - is not the consequence of the cancerous activity of malignant cells but is itself a cancerous event.
