Scientists identify specific enzymes that make meningitis hard to fight

Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremely virulent, have been identified in new research published today.

Pregnancy hormone prolactin gives hope to MS victims

Canadian scientists believe they may be some way to solving the mystery of why women suffering from multiple sclerosis (MS) go into remission while they are pregnant.

Experimental vector vaccine reduces stillbirths from cytomegalovirus

Researchers funded by the National Institutes of Health have developed an experimental vaccine that reduces stillbirths among rodents born to mothers infected with cytomegalovirus (CMV) - a common virus that can also cause mental retardation and hearing loss in newborn children who were infected in early fetal life.

Imaging of disease dynamics during meningococcal sepsis

Each year 170,000 people around the world die of this type of meningitis, according to the World Health Organization, (WHO).

Gardasil reaction report released

The National Vaccine Information Center (NVIC) today released a new analysis of the federal Vaccine Adverse Event Reporting System (VAERS) reports of serious health problems following HPV vaccination (Merck's Gardasil) during the last six months of 2006.

New test identifies suitable lymphoma patients likely to respond to new therapy

Researchers at the Albert Einstein College of Medicine of Yeshiva University have discovered a genetic signature identifying cases of lymphoma that are uniquely susceptible to a newly developed molecular targeted therapy. As a result, physicians organizing clinical trials of the new therapy will be able to enroll patients who'll be most likely to benefit from it.

Hormone prolactin key to repairing nerve cell damage

The mystery of why multiple sclerosis (MS) tends to go into remission while women are pregnant may be the secret to overcoming the devastating neurodegenerative disease, according to University of Calgary researchers who have shown that a pregnancy-related hormone is responsible for rebuilding the protective coating around nerve cells.

Chemotherapy drug bortezomib packs a one-two punch

Cancer can be wily, and those who treat the disease have amassed a wide array of weapons with which to fight it and kill tumors.

siRNA delivery into human T cells and primary cells with carbon-nanotube transporters

A promising approach to gene therapy involves short DNA fragments (interfering RNA) that bind to specific genes and block their "translation" into the corresponding, disease-related protein.

How T cells attack tumors

Our immune system struggles to eliminate tumors effectively. By unraveling its strategies, we can enhance its effects on tumor cells and so improve the clinical prospects of cancer immunotherapy.

Scientists label cells with magnetic nanoparticles

Investigators at the German Cancer Research Center have developed silica-coated iron oxide nanoparticles that allow for cell tracking in a live animal using magnetic resonance imaging (MRI).

Food scare number 4 this week - chicken breast meat

In yet another food scare in the United States a nationwide recall of 52,650 pounds of Oscar Mayer ready to eat chicken breast strips is suspected to be contaminated.

RNAi shows promise in gene therapy

Three years ago Mark Kay, MD, PhD, published the first results showing that a biological phenomenon called RNA interference could be an effective gene therapy technique. Since then he has used RNAi gene therapy to effectively shut down the viruses that cause hepatitis and HIV in mice.

More evidence that inflammation can fuel cancer

As evidence mounts that the body's normally protective inflammation response can drive some precancerous tissues to become fully malignant, UCSF scientists report discovering an apparent trigger to this potentially deadly process.

Scientists discover vulnerable area on HIV that could lead to development of HIV/AIDS vaccine

Scientists on Wednesday announced they had identified a vulnerable area on HIV that might be susceptible to antibodies and could prevent the virus from infecting human cells, Reuters Health reports. The findings are published in the Feb. 15 issue of the journal Nature.

The present and future for influenza vaccines

The near inevitability that influenza will explode into a pandemic in the coming few years has kept researchers searching for a way to prevent the worst effects of infection. The ultimate prize is a highly effective vaccine that could be produced and deployed rapidly.
