Research reveals that diarrheal bacteria can cause colon cancers

Johns Hopkins scientists say they have figured out how bacteria that cause diarrhea may also be the culprit in some colon cancers. The investigators say that strains of the common Bacteroides fragilis (ETBF) dupe immune system cells into permitting runaway colon tissue inflammation, a precursor for malignant growth.

Discovery of genetic biomarkers enable targeted personalised medication for Colorectal cancer

Colorectal cancer (CRC) is the second leading cause of cancer-related death in the Western world. Fortunately physicians today have an abundance of drug therapies available to improve survival length for more advanced cancer patients. Now the discovery of genetic biomarkers relevant to CRC means that targeted personalised medication is increasingly common.

Research study discovers lethal effects of tetracycline and chloramphenicol against certain bacterial strains

By studying the intricate mechanisms at work in protein production, a Princeton-led team has discovered why certain kinds of antibiotics are so effective. In doing so, they also have discovered how one protein protects against cell death, shedding light on a natural cancer-fighting process.

New strategy found to increase the efficacy of protein-based drugs

A new method for attaching a large protective polymer molecule to a protein appears to improve protein drugs significantly.

FDA approves Hiberix Haemophilus influenzae type b vaccine

In response to a U.S. shortage of a vaccine to protect infants from Haemophilus influenzae type b (Hib), GlaxoSmithKline (NYSE: GSK) has received accelerated approval from the FDA (Food and Drug Administration) for Hiberix((R)) [Haemophilus b Conjugate Vaccine (Tetanus Toxoid Conjugate)] as a booster dose in children 15 months through four years of age. Hib is an often severe and potentially deadly bacterial infection that can cause meningitis.

Research study highlights the biological importance of Vitamin D in humans and other primates

A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans - but no other known animal species.

New understanding on meningitis cause

A specific protein on the surface of a common bacterial pathogen allows the bacteria to leave the bloodstream and enter the brain, initiating the deadly infection known as meningitis. The new finding, which may guide development of improved vaccines to protect those most vulnerable, including young infants and the elderly, is now available online in the Journal of Experimental Medicine.

Tiny magnetic particles guide stem cells to damaged tissue

Microscopic magnetic particles have been used to bring stem cells to sites of cardiovascular injury in a new method designed to increase the capacity of cells to repair damaged tissue, UCL scientists announced today.

Scientists harness carbon nanomaterials for drug delivery, oxygen sensors

Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.

Mother's immune system may block fetal treatments for blood diseases

Pediatric researchers have resolved an apparent contradiction in the field of prenatal cell transplantation - a medical approach that holds future promise in correcting sickle cell disease and other serious congenital blood disorders. In a new study in animals, the researchers showed that the mother's immune response interferes with the offspring's earlier ability to tolerate transplanted donor cells.

Research on blood transfusions points to a potential risk of transfusing donated platelets

Doctors have noticed a pattern in performing bone marrow transplants as a cure for diseases involving bone marrow failure: more transfusions before a bone marrow transplant correlates with a higher likelihood of rejection, says James Zimring, MD, PhD, assistant professor of pathology and laboratory medicine at Emory University School of Medicine.

New insights into identifying children at risk for autoimmune brain disorders

A new study by researchers at Columbia University Mailman School of Public Health's Center for Infection and Immunity indicates that pediatric obsessive-compulsive disorder (OCD), Tourette syndrome and/or tic disorder may develop from an inappropriate immune response to the bacteria causing common throat infections.

Seattle Genetics reaches milestone under collaboration agreement with MedImmune

Seattle Genetics, Inc. (NASDAQ:SGEN), announced today that it has achieved a milestone under its antibody-drug conjugate (ADC) collaboration agreement with MedImmune, LLC, a wholly owned subsidiary of AstraZeneca. The milestone was triggered by MedImmune’s initiation of a phase I clinical trial of MEDI-547, its anti-EphA2 ADC for solid tumors.

Researchers launch study into search-and-destroy antigen for deadly skin cancer

UT Southwestern Medical Center researchers are studying a new antigen to see whether it can track down and kill cancer cells in patients with recurring melanoma, the leading cause of skin cancer deaths.

Cephalon, Inc. completes acquisition of Arana Therapeutics

Cephalon, Inc. (Nasdaq: CEPH) announced today that it has completed its previously announced acquisition of all of the outstanding ordinary shares of Australian biotechnology company, Arana Therapeutics Limited. As a result of the acquisition, Arana is now a wholly-owned subsidiary of Cephalon.

Novel approach for developing an AIDS vaccine

Researchers at the Yerkes National Primate Research Center, Emory University, believe conventional vaccine strategies should not be the only avenue explored in the development of an effective AIDS vaccine.

Reversible cell-specific drug delivery with aptamer-functionalized liposomes

For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug must also spare healthy cells, and - ideally - its effects will be reversible, to cut short any potentially dangerous side effects.

Phase 1 clinical trial starts for new antibody aimed at hepatitis C virus

Building upon a series of successful preclinical studies, researchers at MassBiologics of the University of Massachusetts Medical School (UMMS) today announced the beginning of a Phase 1 clinical trial, testing the safety and activity of a human monoclonal antibody they developed that can neutralize the Hepatitis C virus (HCV).

Protein DNA repair complex key to avoiding DNA repair mistakes

As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows.

Discovery of potential candidate protein for cancer vaccines

Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. The finding suggests that a vaccine against the protein might prevent malignancies in high-risk individuals.
