Preclinical evidence demonstrates link between psoriasis and cardiovascular disease

The link between psoriasis and cardiovascular events has been observed for years, however the mechanics were unknown. For the first time, Case Western Reserve University School of Medicine researchers have discovered preclinical evidence demonstrating that the inflammatory skin disease leads to cardiovascular disease. Further, the research demonstrated that aggressive reversal of psoriasis reduces the cardiovascular risk as well.

New technique measures brain activity in large populations of nerve cells

Researchers have developed a new technique which allows them to measure brain activity in large populations of nerve cells at the resolution of individual cells. The technique, reported today in the journal Nature, has been developed in zebrafish to represent a simplified model of how brain regions work together to flexibly control behaviour.

BBI from soybeans shows promise against cancer

Soybeans soaking in warm water could become a new "green" source for production of a cancer-fighting substance now manufactured in a complicated and time-consuming industrial process, scientists are reporting in ACS' Journal of Agricultural and Food Chemistry.

Novel tiny spectrometer can detect food quality

Whether fruit, meat or cheese - the quality of food is not always as consumers would like it to be. But, in future, a spectrometer will allow them to gage the quality of food before they buy it. No bigger than a sugar cube, the device is inexpensive to manufacture and could one day even be installed in smartphones.

Researchers use clever screening methods to speed vaccine production

Infectious diseases-both old and new-continue to exact a devastating toll, causing some 13 million fatalities per year around the world. Vaccines remain the best line of defense against deadly pathogens and now Kathryn Sykes and Stephen Johnston, researchers at Arizona State University's Biodesign Institute, along with co-author Michael McGuire from the University of Texas Southwestern Medical Center are using clever functional screening methods to attempt to speed new vaccines into production that are both safer and more potent.

Treatment with IL-12 triggers T cell exhaustion in cancer patients

Rather than stimulating immune cells to more effectively battle cancerous tumors, treatment with the protein interleukin-12 (IL-12) has the opposite effect, driving these intracellular fighters to exhaustion, a Mayo Clinic study has found.

KLF15 molecule inhibits action of estrogen in the endometrium

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a molecule that inhibits the action of estrogen. This female hormone plays a key role in the growth, maintenance and repair of reproductive tissues and fuels the development of endometrial and breast cancers.

Scientists develop new method to directly identify miRNA targets in cells

Human cells are thought to produce thousands of different microRNAs (miRNAs)-small pieces of genetic material that help determine which genes are turned on or off at a given time. miRNAs are an important part of normal cellular function, but they can also contribute to human disease-some are elevated in certain tumors, for example, where they promote cell survival.

IDRI, Aeras partner to develop new TB vaccine candidate

Aeras and the Infectious Disease Research Institute (IDRI) announce today a new agreement to conduct joint development activities with respect to IDRI's novel tuberculosis vaccine candidate. This collaboration reflects the missions of the two non-profit product development partnerships to use cutting-edge science to develop products that address critical diseases of underserved populations around the world, including tuberculosis.

Chronic exposure to cocaine drives structural changes in the brain

Chronic exposure to cocaine reduces the expression of a protein known to regulate brain plasticity, according to new, in vivo research on the molecular basis of cocaine addiction. That reduction drives structural changes in the brain, which produce greater sensitivity to the rewarding effects of cocaine.

UMD researchers design molecular container that can increase solubility of drugs

A cross-disciplinary team of researchers at the University of Maryland has designed a molecular container that can hold drug molecules and increase their solubility, in one case up to nearly 3000 times. Their discovery opens the possibility of rehabilitating drug candidates that were insufficiently soluble. It also offers an opportunity to improve successful drugs that could be made even better with better solubility.

Bumped kinase inhibitors may control malaria

Over 200 million people contract malaria each year, and according to the World Health Organization, an estimated 655,000 people died from malaria in 2010. Malaria is caused by the parasite Plasmodium, which is transmitted to humans through mosquito bites. More effective control of malaria will require the development of new tools to prevent new infections.

Rutin may inhibit formation of blood clots

A compound called rutin, commonly found in fruits and vegetables and sold over the counter as a dietary supplement, has been shown to inhibit the formation of blood clots in an animal model of thrombosis.

Study shows how adolescent cannabis use can cause schizophrenia

New research from the Royal College of Surgeons in Ireland (RCSI) published in Nature's Neuropsychopharmacology has shown physical changes to exist in specific brain areas implicated in schizophrenia following the use of cannabis during adolescence. The research has shown how cannabis use during adolescence can interact with a gene, called the COMT gene, to cause physical changes in the brain.

Researchers discover location and effect of abnormal heart proteins

University of Guelph researchers have found the location and effect of abnormal heart proteins that can cause cardiac failure, a discovery that points to potential new ways to treat the most costly health problem in the world.

iBio receives U.S. patent for iBioModulator platform

iBio, Inc. today announced issuance of a US patent covering compositions of matter and methods of use of modified lichenase B polypeptides comprising the Company's iBioModulator platform.

Molecule that starts DNA repairs also halts them

Repairing DNA breaks can save a cell's life - but shutting off the repair machinery can be just as critical. How cells accomplish this feat was unknown. However, new research by Johns Hopkins scientists, published in the Feb. 22 issue of Nature, suggests that shutting down the repair machinery relies heavily on the same molecule used to start repair in the first place.

Chemically altered proteins may be key to understanding memories

Having a fat head may not be a bad thing, according to new findings at The Johns Hopkins University. As reported in the February 9 issue of Neuron, researchers have made a significant discovery as to how adding fat molecules to proteins can influence the brain circuitry controlling cognitive function, including learning and memory.

'Good' cholesterol may not protect against coronary heart disease

A new study by Harvard School of Public Health (HSPH) researchers has found that a subclass of high-density lipoprotein (HDL) cholesterol, the so-called "good" cholesterol, may not protect against coronary heart disease (CHD) and in fact may be harmful.

Research grants on facioscapulohumeral dystrophy prove useful as genetic basis is found

Businessman Bill Moss’s determination to fight his untreatable muscle-wasting disease may have paid off. Four years ago, Mr Moss, a former Macquarie Bank Executive Director, established a charitable research foundation, FSHD Global, which partly funded the Italian researchers who made the breakthrough.
