CUMC researchers clarify three fundamental issues about Alzheimer's disease

Using high-resolution functional MRI imaging in patients with Alzheimer's disease and in mouse models of the disease, Columbia University Medical Center researchers have clarified three fundamental issues about Alzheimer's: where it starts, why it starts there, and how it spreads. In addition to advancing understanding of Alzheimer's, the findings could improve early detection of the disease, when drugs may be most effective.

Researchers investigate how androgen receptors affect prostate cancer progression

Approximately 1 out of every 6 American men will be diagnosed with prostate cancer, and this year alone there are expected to be nearly a quarter of a million new cases diagnosed, making prostate cancer the most common malignancy among men in the United States. Center for Nuclear Receptors & Cell Signaling Assistant Professor Daniel Frigo and his research team recently published a study investigating the processes through which androgen receptors affect prostate cancer progression.

Study reveals that K-Ras gene mutations behave in ways that subvert normal mechanisms of cell death

Cells with a mutation in the gene called K-Ras—found in close to 30 percent of all cancers, but mostly those with worst prognosis, such as pancreatic cancer, colon cancer, and lung cancer—behave in ways that subvert the normal mechanisms of cell death, according to a cell-culture study by researchers from Huntsman Cancer Institute (HCI) at the University of Utah.

Newly-discovered selective process may explain why brain function does not deteriorate

As we grow older, our brains undergo a major reorganisation reducing the connections in the brain. Studying people up to the age of 40, scientists led by Dr Marcus Kaiser and Ms Sol Lim at Newcastle University found that while overall connections in the brain get streamlined, long-distance connections that are crucial for integrating information are preserved.

New antibody could boost strength, muscle mass in patients with cancer and other diseases

A new antibody could dramatically boost strength and muscle mass in patients with cancer, chronic obstructive pulmonary disease, sporadic inclusion body myositis, and in elderly patients with sarcopenia according to research published ahead of print in the journal Molecular and Cellular Biology.

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.

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.
