Study identifies mechanism by which bacterium S. aureus colonizes nasal passages

A collaboration between researchers at the School of Biochemistry and Immunology and the Department of Microbiology at Trinity College Dublin has identified a mechanism by which the bacterium Staphylococcus aureus (S. aureus) colonizes our nasal passages. The study, published today in the Open Access journal PLOS Pathogens, shows for the first time that a protein located on the bacterial surface called clumping factor B (ClfB) has high affinity for the skin protein loricrin.

Hepatitis C virus takes over invaded cell by hijacking protein making machinery

Researchers at the University of Colorado School of Medicine have figured out intimate details of how the hepatitis C virus takes over an invaded cell, a breakthrough that could point to way for new treatments for the virus.

Scientists identify molecular mechanism central to development of osteoarthritis pain

Researchers at Rush University Medical Center, in collaboration with researchers at Northwestern University, have identified a molecular mechanism central to the development of osteoarthritis (OA) pain, a finding that could have major implications for future treatment of this often-debilitating condition.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

New light on how epigenetic signals may function together to determine fate of stem cell

Long-standing research efforts have been focused on understanding how stem cells, cells capable of transforming into any type of cell in the body, are capable of being programmed down a defined path to contribute to the development of a specific organ like a heart, lung, or kidney. Research from the University of North Carolina at Chapel Hill School of Medicine has shed new light on how epigenetic signals may function together to determine the ultimate fate of a stem cell.

Researchers develop unique approach to calpain inhibition

Calpain, a calcium-regulated enzyme, is essential to a host of cellular processes, but can cause severe problems in its overactivated state. It has been implicated as a factor in muscular dystrophy, AIDS, Alzheimer's disease, multiple sclerosis, and cancer. As such, finding and exploiting calpain inhibitors is an important area of research.

Cellular metabolism of immune cells protect against viral infections and tumours

New research demonstrates that the cellular metabolism of certain immune cells is closely linked to their function, which includes protecting against viral infections and the development of tumours.

Novel testing reaction based on magnetic resonance data

In their quest for new agents, pharmaceutical researchers test millions of substances all over the world. They like using color-forming reactions to identify new molecules. However, in intensively colored solutions or in the case of mixtures with multiple substances these tests fail.

CAC test can identify diabetes patients at high risk of fatal cardiovascular disease

People with Type 2 diabetes have two to four times the risk of cardiovascular disease compared to people without the disease. The best way for doctors to predict which diabetes patients are at the greatest risk for heart disease is to use a coronary artery calcium (CAC) test in addition to the most commonly used assessment tool, according to researchers at Wake Forest Baptist Medical Center.

Ebselen effectively inhibits thioredoxin reductase system in H. pylori, M. tuberculosis

A drug currently being used to treat ischemic strokes may prove to be a significant advance in the treatment of tuberculosis and ulcers. In a new research report appearing online in The FASEB Journal, a compound called ebselen effectively inhibits the thioredoxin reductase system in a wide variety of bacteria, including Helicobacter pylori which causes gastric ulcers and Mycobacterium tuberculosis which causes tuberculosis.

Investigators report non-coding miRNAs as appealing biomarkers for cancer malignancy

As many as 50 percent of all human protein-coding genes are regulated by microRNA (miRNA) molecules. While some miRNAs impact onset and progression of cancer, others can actually suppress the development of malignant tumors and are useful in cancer therapy. They can also serve as potential biomarkers for early cancer detection. In a new issue of Cancer Biomarkers, investigators report on non-coding miRNAs as appealing biomarkers for malignancy.

New antibiotic principle for fighting bacterial infections

Scientists at Karolinska Institutet in Sweden have presented a new principle for fighting bacterial infections, in other words, a new type of antibiotic, in the FASEB Journal.

BubR1 and its associated regulators promising targets for aging disorders and cancer

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. The findings appear in today's online issue of Nature Cell Biology.

Researchers identify possible heredity mechanism that predisposes children to ALL

Researchers at the Sainte-Justine University Hospital Center and the University of Montreal have found a possible heredity mechanism that predisposes children to acute lymphoblastic leukemia (ALL), the most common type of blood cancer in children. According to their findings published in Genome Research, the presence of a genetic defect in the egg or sperm from which children having ALL arise may be a prerequisite for the disease to develop.

Increased life expectancy not benefitting everybody equally: U of T

Global lifespans have risen dramatically in the past 40 years, but the increased life expectancy is not benefitting everybody equally, say University of Toronto researchers. In particular, adult males from low- and middle-income countries are losing ground.

Educational intervention increases calcium intake and retards bone loss in postmenopausal women

Today at the International Osteoporosis Foundation's Asia-Pacific Osteoporosis Meeting, researchers from the National Institute of Nutrition in Hanoi presented a new research study that showed the benefits of educational intervention in increasing calcium intake and retarding bone loss in postmenopausal women.

UBC researcher helps create new gel that could glue blood vessels back together

A University of British Columbia researcher has helped create a gel - based on the mussel's knack for clinging to rocks, piers and boat hulls - that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.
