New chemotherapy pill shows promise for stubborn lymphomas

A new chemotherapy pill is showing early success in treating people with stubborn lymphomas, according to scientists at the University of Rochester Medical Center. Doctors reported that the drug is halting disease in nearly half of the patients with chronic lymphocytic leukemia, and in patients with more aggressive lymphoma as well.

Discovery of 11 new gene sites that influence cholesterol or triglyceride levels

An international research team has identified 11 novel locations in the human genome where common variations appear to influence cholesterol or triglyceride levels, bringing the total number of lipid-associated genes to 30.

Rituxan in combination with chemo improves survival in chronic lymphocytic leukemia

Genentech, Inc. and Biogen Idec have announced that two global Phase III studies in chronic lymphocytic leukemia (CLL), CLL8 and REACH, showed Rituxan (rituximab) plus chemotherapy significantly increased the time patients lived without their disease advancing, as defined by the primary endpoint of progression-free survival (PFS), when compared to chemotherapy alone.

New approaches to prevent blood clots

The largest study ever to examine the preventive use of blood-thinning medication to help prevent deadly blood clots in patients with cancer undergoing chemotherapy presented December 7 during the 50th Annual Meeting of the American Society of Hematology in San Francisco, CA.

Study links cone death in retinitis pigmentosa to metabolic problem

Rods and cones coexist peacefully in healthy retinas. Both types of cells occupy the same layer of tissue and send signals when they detect light, which is the first step in vision.

Scientists create infectious prion disease in mouse model

A worldwide group of scientists has created an infectious prion disease in a mouse model, in a step that may help unravel the mystery of this progressive disease that affects the nervous system in humans and animals.

Biomarkers in blood could aid diagnosis of two severe and debilitating forms of malaria

Canadian researchers have identified protein biomarkers that shed new light on the development of two severe and debilitating forms of malaria.

Allos Therapeutics announces results from phase 2 trial of Pralatrexate in peripheral T-cell lymphoma

Allos Therapeutics, Inc. has announced preliminary top line results from PROPEL, the Company's pivotal Phase 2 trial of pralatrexate (PDX) in patients with relapsed or refractory peripheral T-cell lymphoma (PTCL), at the 50th Annual Meeting of the American Society of Hematology (abstract 261).

Anti-seizure drug Epilim shows promise for Alzheimer's

A drug commonly used to treat epilepsy could help clear the plaques in the brain associated with Alzheimer's disease, according to researchers at the University of Leeds. The plaques are known to lead to the progressive death of nerve cells in the brain linked to many forms of dementia.

Genes for nine health indicators: Population study finds genetics clues

A new genome-wide study examines genetic variants associated with nine metabolic traits and is the first to draw out novel variants from a population unselected for current disease. The traits are indicators for common disease such as cardiovascular disease, type 2 diabetes, blood pressure, inflammation and lipid levels.

Zinc key to formation of hospital-acquired infections

Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of Americans.

Well-armed immune cells help long-term non-progressors contain HIV

To help develop an effective HIV vaccine, researchers are trying to better understand how the immune systems of a small minority of HIV-infected people known as long-term non-progressors (LTNPs) contain the virus naturally.

Vitamin E supplementation may reduce inflammation in the brain

With up to half of a person's body mass consisting of skeletal muscle, chronic inflammation of those muscles - which include those found in the limbs - can result in significant physical impairment.

Breakthrough in understanding the phenomenon of nucleolar dominance

Since the machinery involved in nucleolar dominance is some of the same machinery that can go haywire in diseases such as cancer, Pikaard and his collaborators' research may have important implications for applied medical research.

Discovery of groundbreaking technique for body to accept gene therapy

Researchers at Columbia University Medical Center and the State University of New York at Stony Brook (SUNY) have developed a groundbreaking technique to sneak therapeutic genes past the body's defenses, possibly clearing one of the largest hurdles to realizing the potentials of medically altering a patient's DNA.

New insights into cell division

Biologists have discovered a mechanism that is critical to cytokinesis -- nature's completion of mitosis, where a cell divides into two identical daughter cells.

Breakthrough in sickle cell disease and thalassemia research

Researchers have identified a gene that directly affects the production of a form of hemoglobin that is instrumental in modifying the severity of the inherited blood disorders sickle cell disease and thalassemia.

Stem cells derived from bone marrow may offer novel therapeutic option for epidermolysis bullosa

Stem cells derived from bone marrow may serve as a novel therapeutic option to treat a disease called epidermolysis bullosa (EB), a disorder characterized by extraordinarily fragile skin, according to a study prepublished online in Blood, the official journal of the American Society of Hematology.

Doing the math for membranes

Determining the mechanisms that shape biological membranes has long been a tricky business. Like a factory assembly line, eukaryotic cells are organized into membrane-bound, functional compartments called organelles.
