Novel imaging techniques improve post heart attack survival rates in mouse model

Human adult stem cells injected around the damage caused by a heart attack survived in the heart and improved its pumping efficiency for a year in a mouse model, researchers at The University of Texas MD Anderson Cancer Center report online ahead of publication in Circulation Research.

Animal study reveals intestinal bacteria can promote tumor growth

A team of University of California, San Diego School of Medicine researchers has discovered that common intestinal bacteria appear to promote tumor growths in genetically susceptible mice, but that tumorigenesis can be suppressed if the mice are exposed to an inhibiting protein enzyme.

Sagacity may have a neurobiological basis

In 2009, Dilip V. Jeste, MD, and Thomas W. Meeks, MD, both professors in the department of psychiatry at the University of California, San Diego and researchers at the Sam and Rose Stein Institute for Research on Aging, published a paper proposing that sagacity might have a neurobiological basis.

Ancient DNA sequences within human cells can help cancer cells survive: Study

A new study in the journal Nature Medicine, part-funded by Cancer Research UK, has discovered that ancient DNA sequences within human cells can actually help cancer cells survive - at least in one type of the disease.

Inflammation enzyme regulates production of brown fat tissue

Love handles, muffin tops and stomach tires - white fat tissue forms the typical curves in the notorious problem areas to store energy. Exactly the opposite happens in brown fat tissue: Instead of being stored, energy gets transformed into heat. To the dismay of many people, adults have only small amounts of this energy burner. By contrast, babies and animals in hibernation have lots of it in their bodies where it serves for heat regulation.

Report: 34 C>G of PPAR-γ gene might be a potential therapeutic target for colon cancer

Colorectal cancer is one of the major causes of cancer death in the developed countries. Accumulated evidences indicate that lipid metabolism, especially the one in the arachidonic acid -pathway, appears to play a critical role in the development of CRC.

New report: Evaluation of Biomarkers and Surrogate Endpoints in Chronic Disease

Claims about the health benefits of foods and nutritional supplements have proliferated in recent years, most of them based on studies measuring ingredients' effects on biomarkers as substitutes for actual clinical outcomes.

Chemical changes in genetic material regulate activity of many genes

Chemical changes in the genetic material, known as epigenetic modifications, regulate the activity of many genes. Thus, attachment of methyl groups to DNA often inactivates important cellular growth brakes. Therefore, this process called methylation is believed to be a major cause of uncontrolled division of cancer cells. Specific enzymes, the DNA methyltransferases, are responsible for methylation.

Researchers investigate aberrant expression of nuclear matrix proteins in gastric cancer cells

Gastric cancer is the most common malignant gastrointestinal cancer and accounts for 25% of cancer deaths. Nuclear matrix, a filamentous protein framework for eukaryotic cellular chromatin, closely relates to DNA duplication and transcription. Research on nuclear matrix proteins will provide insight into how tumors developed.

Encouraging B. anthracis to unwittingly unmask itself will help eradicate the pathogen

Anthrax-causing bacteria can be engineered to shed their invisibility cloaks, making it easier for the immune system to eradicate it, according to a new study published in Microbiology. The work could lead to new measures to treat anthrax infection in the event of a biological warfare attack.

Cytori Therapeutics to initiate European medical device approval study for Celution System

The first clinical trial of adipose (fat) tissue-derived stem and regenerative cells for the treatment of heart attacks showed a substantial reduction in the size of injury to the heart, an improvement in the amount of blood supply to the heart muscle, and a corresponding functional improvement in the amount of blood the heart can pump.

Plant breeding can be used to produce new types of wheat with enhanced health benefits

Wheat products, and in particular, wholegrain products, are important sources of dietary fibre, vitamins, minerals and other components which are beneficial for human health. Analysis of a diverse range of wheat varieties within the HEALTHGRAIN project of the European Union has shown substantial variation (up to four-fold) in the content and composition of these components.

Fragile X syndrome iPS cells and embryonic stem cells behave differently: Study

In the last three years, a new technique for reprogramming adult cells has given scientists an easier and less controversial way to harness the power of embryonic-like stem cells to study human disease from its earliest beginnings in hopes of gleaning new insights into the root causes of disease and developing new therapies.

Manual provides laboratory methods, information and resources on new collection of model species

Mice, frogs, and E. coli are standard organisms in biology laboratories. But in the last few years, due in part to technical advances, the reduced costs of genome sequencing, and increased interest in evolution and development, the range of organisms used for research has greatly expanded. Scientists now have more flexibility in choosing a model system that might better address their specific research question.

Closer to understanding age-related memory loss and drug to boost memory

The world's scientific community may be one step closer to understanding age-related memory loss, and to developing a drug that might help boost memory. In an editorial published May 7 in Science, J. David Sweatt, Ph.D., chair of the University of Alabama at Birmingham (UAB) Department of Neurobiology, says that drugs known as histone deacetylase inhibitors are showing great promise in stopping memory loss - and even in boosting the formation of memory in animal models.

DNA capture techniques enable sequencing of ancient Neandertal DNA

Researchers from the Max Planck Institute (MPI), Cold Spring Harbor Laboratory (CSHL), Agilent Technologies Inc., and other prestigious institutions worldwide have shown that DNA capture techniques can greatly enable the sequencing of ancient Neandertal DNA, providing new insight into the nature of these prehistoric hominids.

ETH Zurich researchers discover HIV transmission chains

Since the emergence of the first AIDS cases in the early 1980s, an infectious wave has spread over Switzerland. Every year, several hundred people are infected with the HI-virus which triggers the acquired immunodeficiency syndrome, AIDS. Does the infection spread according to a particular pattern? Do these patterns vary among the transmission groups such as drug addicts, homosexual or heterosexual persons?
