Left ventricular hypertrophy prevalent in lung disease patients

The prevalence of left ventricular hypertrophy is increased in normoxemic patients with chronic obstructive pulmonary disease, results from a pilot study suggest.

Children with eczema have distinct gut microbiome

Infants with eczema have more diverse total gut microbiota than those without the skin condition, show study findings.

Study shows promising results for cancer treatment

The plasma membrane transporter SLC5A8 can inhibit the spread of tumours by decreasing the amount of the anti-apoptotic protein surviving in tumour cells.

New hope for lupus patients

A clinical trial with 149 patients suffering from the very disabling autoimmune disease systemic lupus erythematosus, has shown the effectiveness of a synthetic peptide developed by a team of researchers led by CNRS biologist Slyviane Muller at the Institut de Biologie Moleculaire (IBMC) in Strasbourg, France.

Researchers discover unique hairpin-like structure that facilitates Abeta clumping

Alzheimer's disease is the most common cause of late-life dementia. The disorder is thought to be caused by a protein known as the amyloid-beta protein, or Abeta, which clumps together in the brain, forming plaques that are thought to destroy neurons. This destruction starts early, too, and can presage clinical signs of the disease by up to 20 years.

Enterococcal cytolysin synthetase helps form distinctly different, 3-D protein ring structures

While working out the structure of a cell-killing protein produced by some strains of the bacterium Enterococcus faecalis, researchers stumbled on a bit of unusual biochemistry. They found that a single enzyme helps form distinctly different, three-dimensional ring structures in the protein, one of which had never been observed before.

Researchers report novel charge zipper principle used by proteins to form functional units

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane.

Blocking interaction of JNK enzyme may counteract neuron destruction

Oxidative stress is a primary villain in a host of diseases that range from cancer and heart failure to Alzheimer's disease, Amyotrophic Lateral Sclerosis and Parkinson's disease.

PKM-zeta-less adult mice still able to form long-term memories

A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation - that it hinges on a single enzyme in the brain - is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.

Kareus announces start of KU-046 Phase I study in Alzheimer's

Kareus Therapeutics SA, the private biotechnology company focused on the development of novel therapeutics for the unmet treatment of age-related and chronic diseases, today announces the start of a Phase I clinical study following the Investigational New Drug (IND) approval from the US Food and Drug Administration for the development of KU-046, a first-in-class disease modifying new chemical entity discovered for the treatment of Alzheimer's disease using Kareus' proprietary bioenergetics and KARLECT platforms.

Aeterna Zentaris reaches SPA agreement with FDA for AEZS-108 Phase 3 trial in endometrial cancer

Aeterna Zentaris Inc. today announced that it has reached an agreement with the U.S. Food and Drug Administration ("FDA") on a Special Protocol Assessment ("SPA") for an upcoming Phase 3 registration trial in endometrial cancer with its doxorubicin peptide conjugate, AEZS-108. The SPA agreement states that the proposed trial protocol design, clinical endpoints and planned analyses are acceptable to the FDA to support a regulatory submission.

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.

Protein in human blood platelets points to a new weapon against malaria

One of the world's most devastating diseases is malaria, responsible for at least a million deaths annually, despite global efforts to combat it. Researchers from the Perelman School of Medicine at the University of Pennsylvania, working with collaborators from Drexel University, The Children's Hospital of Philadelphia, and Johns Hopkins University, have identified a protein in human blood platelets that points to a powerful new weapon against the disease. Their work was published in this months' issue of Cell Host and Microbe.

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.

Pergamum’s DPK-060 Phase II trial on acute external otitis meets primary end-point

Pergamum AB announced today that the primary end-point was met in the randomized Phase II trial of DPK-060 for treatment of acute external otitis.

Study finds new signaling pathway involved in development of chronic inflammation of brain cells

The number of Alzheimer's patients will continue to dramatically increase in the next several decades. Various teams of researchers worldwide are feverishly investigating precisely how the illness develops. A

GI bacteria exert some control over their hosts' appetites: Review

Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals. Now Vic Norris of the University of Rouen, France, and coauthors propose yet another role for GI bacteria: that they exert some control over their hosts' appetites.

Adiponectin flags up pancreatic cancer risk

Circulating levels of adiponectin may provide a novel marker for identifying individuals who are at an increased risk for pancreatic cancer, report researchers.

Metallic probe can detect fibrils from misfolded proteins in real time

Rice University scientists have discovered a new way to look inside living cells and see the insoluble fibrillar deposits associated with Parkinson's disease.

New MIT technology may help make cancer biomarker detection much easier

Finding ways to diagnose cancer earlier could greatly improve the chances of survival for many patients. One way to do this is to look for specific proteins secreted by cancer cells, which circulate in the bloodstream. However, the quantity of these biomarkers is so low that detecting them has proven difficult.
