Researchers make white fat take on characteristics of brown fat

Brown seems to be the color of choice when it comes to the types of fat cells in our bodies. Brown fat expends energy, while its counterpart, white fat stores it. The danger in white fat cells, along with the increased risk for diabetes and heart disease it poses, seems especially linked to visceral fat. Visceral fat is the build-up of fat around the organs in the belly.

Large-scale, patient-specific simulations of blood function

Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.

Scientists determine structure of green pigment seen in nitrite-cured bacon, other meats

As with many concerned consumers, a team of University of Oklahoma researchers wondered if the green color sometimes seen in bacon is, in fact, harmful to human health. Recently, these OU scientists took an important first step in answering this question by determining the structure of the green pigment responsible for this 'nitrite burn.'

New test accurately detects aggressive prostate cancer

One in six men will be diagnosed with prostate cancer during his lifetime, the second leading cause of death among men in the United States. It's a serious problem and current diagnostic tests aren't very specific. But a research team at the University of Central Florida NanoScience Technology Center has found a more accurate test that not only determines whether a patient has prostate cancer, but also how aggressive it is.

Researchers discover intra-cellular function of LOXL2 protein

Researchers at the Hospital de Mar Research Institute (IMIM) have discovered that the protein LOXL2 has a function within the cell nucleus thus far unknown. They have also described a new chemical reaction of this protein on histone H3 that would be involved in gene silencing, one of which would be involved in the progression of breast, larynx, lung and skin tumours.

Transgenic mice to visualize metastasis and inflammation

One of the major routes of tumor cell dissemination to form metastasis at distant organs in the body is the lymphatic system. To study this process, still poorly understood, and to gain information on which tumors prefer this route for dissemination and how to block it, researchers of the Spanish National Cancer Research Center, led by researcher Sagrario Ortega, have created transgenic mice in which, for the first time, the growth of the lymphatic vessels can be visualized in the whole animal, by a light-emitting reaction, as tumor progresses and forms metastasis.

New method uses E. coli bacteria to engineer human therapeutic glycoproteins

Escherichia coli - a bacteria considered the food safety bane of restaurateurs, grocers and consumers - is a friend. Cornell University biomolecular engineers have learned to use E. coli to produce sugar-modified proteins for making pharmaceuticals cheaper and faster.

X-rays help decipher how natural antibiotics defy a longstanding set of chemical rules

Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules - a mechanism that has baffled organic chemists for decades.

Scientists determine chemical features of DHPS enzyme's active site

More than 70 years after the first sulfa drugs helped to revolutionize medical care and save millions of lives, St. Jude Children's Research Hospital scientists have determined at an atomic level the mechanism these medications use to kill bacteria. The discovery provides the basis for a new generation of antibiotics that would likely be harder for bacteria to resist and cause fewer side effects.

BioConnections, Yissum to commercialize kits that detect MDR and XDR infections

Yissum, the research and development company of the Hebrew University of Jerusalem, had signed a licensing agreement with BioConnections, a UK based microbiology company, for the commercialization of kits that enables immediate detection of all multidrug resistant (MDR) and of any extremely drug resistant (XDR) infections.

Biocompatible interface scaffolds for improved prosthetics

Sandia National Laboratories researchers, using off-the-shelf equipment in a chemistry lab, have been working on ways to improve amputees' control over prosthetics with direct help from their own nervous systems.

Study reveals how mutation shuts down DJ-1 protein's neuroprotective abilities

Purdue University researchers revealed how a mutation in a protein shuts down a protective function needed to prevent the death of neurons in Parkinson's disease, possibly opening the door to new drug strategies to treat the disorder.

Pyromaker can rapidly sequence cancer-driving mutations

Using precise information about an individual's genetic makeup is becoming increasingly routine for developing tailored treatments for breast, lung, colon and other cancers. But techniques used to identify meaningful gene mutations depend on analyzing sequences of both normal and mutant DNA in tumor samples, a process that can yield ambiguous results. Now, a team of Johns Hopkins researchers says it has developed an easy-to-use online computer software application that can clear up any confusion faster and cheaper than other methods currently used to do the job.

Discovery sheds light on what happens in cells when DNA is damaged

A research group in the Faculty of Medicine & Dentistry at the University of Alberta is hoping its latest discovery could one day be used to develop new therapies that target certain types of cancers.

Lycopene can kill prostate cancer cells

A nutrient in cooked tomatoes has been shown in laboratory studies to slow the growth of or even kill prostate cancer cells.

SonoPhoto Dynamic Therapy shows promise against squamous cell carcinoma

George Miller developed an ulcer on his bottom lip that began to bleed. His doctor sent cell scrapings to a pathologist, and diagnosed Miller with squamous cell carcinoma (SCC). According to TMD Limited, a medical tourism company, squamous cell carcinoma is the 2nd most common cancer in humans and other animals.

Detox diets useless – eat less and exercise more for good health

Detox diets may promise to help lose weight and purge the body of poisoning chemicals but the only thing that detox products will help lose is money, a British researcher says.

TAU develops tumor destruction method that also creates immunity

Even when surgical tumor removal is combined with a heavy dose of chemotherapy or radiation, there's no guarantee that the cancer will not return. Now researchers at Tel Aviv University are strengthening the odds in favor of permanent tumor destruction - and an immunity to the cancer's return - with a new method of tumor removal.

New technique to accomplish 'accelerated serendipity' using robotics

Scientists can now take that "a-ha" moment to go with a method Princeton University researchers developed - and successfully tested - to speed up the chances of an unexpected yet groundbreaking chemical discovery.
