Researchers discover potential treatment for Friedreich's ataxia

Using clever chemistry, a Scripps Research team has pinpointed the enzyme target of a drug group that stops the progression of the devastating disease Friedreich's ataxia in mice and may do the same for humans. The findings, developed in collaboration with scientists from Repligen Corporation, help advance this treatment approach one step closer toward human clinical trials, which will be a welcome event for disease sufferers who currently have few treatment options.

AABM Team wins two medals in a national contest

The Aquatic Animal Bio-Medicine R&D Team (AABM Team) of National Cheng Kung University (NCKU) in Taiwan, led by Distinguished Prof. Huey-Lang Yang from Institute of Biotechnology, won two medals out of more than 100 teams in the national contest, “2009 Crazy Idea – King of Practical Applications on Creative Researches and Development of Biotechnology,” organized by the Industrial Development Bureau of the Ministry of Economic Affairs, Taiwan.

Researchers develop molecule to confuse insects' ability to detect plants

Biotechnology and Biological Sciences Research Council (BBSRC)-funded research, published this week in Chemical Communications, describes how scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food security.

Researchers to use Intravenous Immune Globulin for slowing AD progression

Researchers from the Memory and Cognition Center at University Hospitals Case Medical Center will begin testing an intriguing new approach to slowing down the progression of Alzheimer's Disease (AD) using Intravenous Immune Globulin (IGIV), also known as gammaglobulin.

Research to improve the targeting of chemotherapeutic drugs to specific cells

Kenneth Longmuir, associate professor of physiology & biophysics, and Richard Robertson, professor of anatomy & neurobiology, used liposomes, small spheres (less-than 100 nanometer in diameter) of naturally-occurring lipid molecules, as "packages" for the cancer chemotherapeutic agent doxorubicin, and a small peptide molecule to "address" the package to the targeted tissue.

Research to develop small-molecule drug that blocks excess iron absorption

Excess iron in the body, if left unchecked, can form toxic deposits in major organs leading to serious conditions including heart failure, diabetes, liver cirrhosis, arthritis, and even infertility. Iron overload can be a consequence of a genetically mutated gene known as hereditary hemochromatosis, or a consequence of red blood cell transfusions, required as life saving treatments, for patients with diseases such as thalassemia.

Researchers study about abnormal gene functioning in mitochondria

Researchers are delving into abnormal gene function in mitochondria, structures within cells that power our lives. Mitochondria are the place where energy is generated from the most basic molecules of food. Because this function is essential to life, defects in mitochondria may affect a wide range of organ systems in humans and animals.

Neuroscience professor receives Institutes of Health Director's New Innovator Award

Leon Reijmers, PhD, assistant professor of neuroscience at Tufts University School of Medicine in Boston, is one of 55 recipients of the National Institutes of Health Director's New Innovator Award. Reijmers is investigating the way memories are stored in the brain, specifically focusing on the proteins involved in long-term memory storage.

Current stem cell applications to be discussed at NJIT

Stem cell researcher Treena Livingston Arinzeh will discuss current stem cell applications at NJIT, including the regeneration of bone and cartilage for bone fracture and osteoarthritis treatments, spinal cord repair, and liver regeneration at NJIT's first Research Caf.

Researchers develop a process to tag cancer cells

Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. Now, a study reviewed by Philip Dawson, a member of Faculty of 1000 Biology and leading authority in chemistry and cell biology, describes a novel labelling technique that uses a chemical reaction to make live cancer cells light up quickly and safely.

Chronic sleep deprivation linked to early incidence of Alzheimer's brain plaques

Chronic sleep deprivation in a mouse model of Alzheimer's disease makes Alzheimer's brain plaques appear earlier and more often, researchers at Washington University School of Medicine in St. Louis report online this week in Science Express.

Moderately elevated levels of ROS positive in fruit flies

It has been known for decades that reactive oxygen species (ROS) - ions or very small molecules that include free radicals - damage cells. But much to their surprise, Jonsson Cancer Center researchers found that in Drosophila, the common fruit fly, moderately elevated levels of ROS are a good thing.

Clostridium difficile's five genetic regions identified

Five genetic regions have been identified that are unique to the most virulent strain of Clostridium difficile (C. difficile), the hospital superbug. Researchers writing in BioMed Central's open access journal Genome Biology studied the genome of the bacterium, looking for genes relating to motility, antibiotic resistance and toxicity.

Matrix metalloproteinase-8 enzyme increases the risk of heart diseases

Scientists at Queen Mary, University of London have made an important discovery in understanding what causes arteries to clog up. They have discovered that an enzyme called matrix metalloproteinase-8 plays a crucial role in raising blood pressure and causing abnormal build-up of cells in the arteries - both of which increase the risk of heart disease.
