New PBC tool for prioritizing laboratory-based CD-4 cell count testing

One of the major problems that has slowed progress toward universal access to life-saving antiretroviral therapy (ART) to treat AIDS in developing nations has been limited availability of laboratories and trained medical staff to conduct blood tests of immune system CD-4 T-cell levels that indicate when to start ART.

Caring for wife with breast cancer can affect men's health

Caring for a wife with breast cancer can have a measurable negative effect on men's health, even years after the cancer diagnosis and completion of treatment, according to recent research.

Coronary stents do not increase risk of heart attack, death in people with metal allergies

Cardiologists have long grappled with how to best manage patients with coronary artery disease who report skin hypersensitivity to nickel or other metal components found in stents -- small tubes placed in narrowed or weakened arteries to help improve blood flow to the heart. But new Mayo Clinic research, published in the April 16, 2012, issue of Circulation: Cardiovascular Interventions, may help allay these concerns.

Two related enzymes play a key role in development of T-ALL

Columbia University Medical Center (CUMC) scientists have demonstrated that two related enzymes - phosphoinositide-3 kinase (PI3K) gamma and delta - play a key role in the development of T-cell acute lymphoblastic leukemia (T-ALL), a highly aggressive childhood leukemia that is difficult to treat.

ALL induction treatment failure should not be an automatic indication for bone marrow transplant

International study that included St. Jude Children's Research Hospital reports some young acute lymphoblastic leukemia patients who fail induction therapy can achieve high cure rates without bone marrow transplantation.

Blocking PRC2 protein may help protect against AML

Scientists at Cold Spring Harbor Laboratory have identified a candidate drug target for treating acute myeloid leukemia, a white blood cell cancer that proliferates out of control in the bone marrow.

Top-line results from Shire's SPD476 phase 3 trial on diverticulitis

Shire plc, the global specialty biopharmaceutical company, today announced top-line results of the PREVENT2 trial, a phase 3 investigational study of once-daily SPD476, MMX mesalamine in patients with a history of diverticulitis.

Commensal bacteria may play an important role in influencing and controlling allergic inflammation

When poet Walt Whitman wrote that we "contain multitudes," he was speaking metaphorically, but he was correct in the literal sense. Every human being carries over 100 trillion individual bacterial cells within the intestine -- ten times more cells than comprise the body itself.

Results from AspenBio Pharma's AppyScore trial on appendicitis to be presented at SAEM meeting

The results from AspenBio Pharma's 503-patient pilot study of AppyScore will be presented from the podium the upcoming West Region meeting of the Society for Academic Emergency Medicine (SAEM) being held in Las Vegas, March 16-17.

Addition of inflammatory biomarkers to clinical variables improve mortality prediction in COPD

The addition of changes in inflammatory biomarkers to established clinical variables improves the prediction of mortality in patients with chronic obstructive pulmonary disease (COPD), according to a new study.

Study addresses how human body controls gamma-herpesviruses

New research from the Trudeau Institute addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers. The study, carried out in the laboratory of Dr. Marcia Blackman, awaits publication in The Journal of Immunology.

New inexpensive medical sensor may simplify diagnosis of diseases

An inexpensive new medical sensor has the potential to simplify the diagnosis of diseases ranging from life-threatening immune deficiencies to the common cold, according to its inventors at the Stanford University School of Medicine.

New HS44 molecule inhibits lung metastasis

One type of white blood cell, the Natural Killer T Cells, fights against infections and tumours by freeing cytokine proteins which activate the body's immune response and destroy infected or malignant cells. To do so they must receive an activation signal. Specific receptors located on their surface act as switches: they activate the lymphocyte in presence of an antigen, a molecule which triggers alarm signals.

Study identifies new processes that lead to development of novel cell implicated in allergies

A collaboration between scientists in Trinity College Dublin and the United Kingdom has identified new processes that lead to the development of a novel cell implicated in allergies. The discovery has the potential for new strategies to treat asthma and other allergic diseases.

Elevated levels of two TLRs can trigger heart disease and diabetes

UC Davis scientists have uncovered a key suspect in the destructive inflammation that underlies heart disease and diabetes. The new research shows elevated levels of a receptor present on leucocytes of the innate immune response in people at risk for these chronic diseases.

Study: 3D organization of chromosomes plays a role in cancer genomics

It is well understood that chromosomal translocation - a process whereby pieces of two chromosomes break off and exchange places - is a hallmark of many cancers including leukemia, thyroid cancer and lymphoma and play an important part in how healthy cells become cancerous. The role spatial proximity plays in why certain chromosomal translocations happen repeatedly, however, has been a long-standing area of debate among scientists.

New genetic resource to accelerate development of novel treatments for diseases

A new genetic resource from an international research consortium is expected to accelerate the development of new cures and treatments for a wide range of human diseases. This project, called the mouse "Collaborative Cross" (CC) resource, will increase the likelihood that experiments conducted in mice will advance our understanding of human biology.

Conventional method has minimal role in determination of PJI

In their search for new, better ways to diagnose periprosthetic joint infection, Rothman Institute at Jefferson researchers have discovered that measurement of C-reactive protein in the synovial fluid is extremely accurate, while measuring a patients- serum white blood cell count (WBC) and the percentage of neutrophils (PMN%), the conventional method for diagnosis, has a minimal role in the determination of PJI.

FDA accepts Genentech's pertuzumab BLA and grants Priority Review

Genentech, a member of the Roche Group, today announced that the U.S. Food and Drug Administration (FDA) has accepted the company's Biologics License Application for pertuzumab and granted Priority Review.

Natural resistance to flu could hold key to universal vaccine

Researchers have found that on infecting 41 healthy volunteers with different strains of flu virus, those with higher levels of a specific type of white blood cell were less likely to develop severe illness. Now the team of researchers hopes to mimic the natural resistance shown by some of the volunteers, by creating a vaccine that boosts levels of a particular subset of the 'T-cells'.
