Scientists solve 50-year mystery behind cholera

For 50 years scientists have been unsure how the bacteria that gives humans cholera manages to resist one of our basic innate immune responses. That mystery has now been solved, thanks to research from biologists at The University of Texas at Austin.

New imaging device can better diagnose chronic ear infections

Doctors can now get a peek behind the eardrum to better diagnose and treat chronic ear infections, thanks to a new medical imaging device invented by University of Illinois researchers. The device could usher in a new suite of non-invasive, 3-D diagnostic imaging tools for primary-care physicians.

Blocking Skp2 protein might inhibit glycolysis and treat breast cancer

HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in the May 25 issue of Cell.

New method can screen for bacterial genes that are expressed during meningitis

Bacterial meningitis is an infection of the meninges, the protective membrane that covers the spinal cord and brain. Children, elderly patients and immunocompromised patients are at a higher risk for the development of severe bacterial meningitis. Recently, researchers at the University of Adelaide in Australia sought to identify new vaccine targets in Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in the world.

New knowledge related to host-parasite interaction in severe malaria

Researchers from Seattle Biomedical Research Institute, the University of Copenhagen and the University of Edinburgh have uncovered new knowledge related to host-parasite interaction in severe malaria, concerning how malaria parasites are able to bind to cells in the brain and cause cerebral malaria - the most lethal form of the disease.

Scientists decipher structure of bacterial injection needles at atomic resolution

The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response.

Research demonstrates how a living cell controls its growth process

A collaboration between Lehigh University physicists and University of Miami biologists addresses an important fundamental question in basic cell biology: How do living cells figure out when and where to grow?

Esperance initiates enrollment in EP-100 and paclitaxel Phase 2 combination trial for ovarian cancer

Esperance Pharmaceuticals today announced that it has begun enrollment of a Phase 2, randomized, multi-center trial of EP-100 in combination with paclitaxel for the potential treatment of advanced ovarian cancer.

FDA clears MAQUET's new MEGA larger volume intra-aortic balloon catheters

MAQUET Cardiovascular LLC, a leading provider of cardiovascular technologies, today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its new MEGA 7.5Fr. 30cc and 40cc intra-aortic balloon (IAB) catheters. These new, larger volume catheters will allow clinicians to provide patients with greater hemodynamic support, regardless of their height.

RNP granules exit the nucleus via new budding mechanism akin to herpes-type viruses

New evidence published in Cell by Vivian Budnik, PhD, Melissa J. Moore, PhD, and colleagues at the University of Massachusetts Medical School, reveals a novel budding mechanism, similar to the process used by some viruses, capable of exporting large ribonucleoprotein particles from the nucleus to the cytoplasm.

MAGI genes play a role in psychiatric disease

These findings are not about the classic story of gift-giving, although the MAGI genes (officially named membrane associated guanylate kinase, WW and PDZ domain containing proteins) do influence brain function in important ways.

Regulatory T cell diversity provides cumulative protective effect against RA

Untangling the root cause of rheumatoid arthritis has been a difficult task for immunologists, as decades of research has pointed to multiple culprits in our immune system, with contradictory lines of evidence. Now, researchers at The Wistar Institute announce that it takes a diverse array of regulatory T cells (a specialized subset of white blood cells) to prevent the immune system from generating the tissue-specific inflammation that is a hallmark of the disease. Regulatory T cell diversity, the researchers say, provides a cumulative protective effect against rheumatoid arthritis. When that diversity is not present, it allows the immune system to attack joints.

Automated way to record electrical activity inside neurons in the living brain

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice it.

Researchers identify new mechanism that causes choroidal neovascularization

Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization.

Researchers investigate hydrogels' potential in drug delivery

The flexible properties of hydrogels - highly absorbent, gelatinous polymers that shrink and expand depending on environmental conditions such as humidity, pH and temperature - have made them ideal for applications from contact lenses to baby diapers and adhesives.

Integral Molecular receives U.S. patent for methodology that generates Lipoparticles

Integral Molecular, a leader in membrane protein reagents and services, announces the issuance of a key patent protecting its methodology for generating Lipoparticles, which provide highly-concentrated membrane proteins in their native conformation for antibody and drug discovery applications focused on membrane protein targets such as G protein-coupled receptors (GPCRs), ion channels, and transporters.

Non-invasive imaging technique measures specific brain chemical changes

Alzheimer's disease (AD) is a major neurodegenerative disorder that affects millions of people worldwide. New and accurate techniques for early diagnosis are critical. Pravat K. Mandal, PhD, and his colleagues have developed a completely non-invasive brain imaging technique to measure specific brain chemical changes. This provides a signature of the early stages of AD from the hippocampal region of the brain.

Symposium at EuroPRevent 2012 highlights benefits of oily fish consumption

Most people, whether healthy or having cardiovascular disease (CVD), would benefit from regular consumption of oily fish, concluded speakers at the EuroPRevent 2012 meeting. While eating whole fish undoubtedly offers the optimum approach for increasing omega-3 intakes in both primary and secondary prevention, delegates heard, supplements have a major role to play in increasing omega-3 intakes for people who do not like fish.

NJIT professor receives $340,000 NIH grant to investigate membrane proteins

NJIT Associate Professor Edgardo Farinas has been awarded today a three-year $340,000 National Institutes of Health (NIH) grant to investigate spores as a protein display platform for the directed evolution of membrane proteins.
