Hematology News and Research

RSS

Hematology, also spelled haematology, is the branch of biology (physiology), pathology, clinical laboratory, internal medicine, and pediatrics that is concerned with the study of blood, the blood-forming organs, and blood diseases. Hematology includes the study of etiology, diagnosis, treatment, prognosis, and prevention of blood diseases.

Can a new combination treatment prevent a secondary stroke in children with sickle cell anemia?

St. Jude Children’s Research Hospital will lead a national Phase III clinical trial to investigate whether a new combination treatment can prevent a secondary stroke in children with sickle cell anemia (SCA) and eliminate the need for nightly injections with a drug that reduces iron overload in these patients.

Unique blood test detects iron deficiency in infants earlier

A unique blood test detects iron deficiency in infants earlier and more accurately than the commonly used hemoglobin screening test, according to a study in the August 24/31 issue of the Journal of the American Medical Association.

First proof of how the rare disorder Fanconi anemia causes chromosomal instability

The scientists found a gene mutation not previously known to be related to Fanconi anemia, and they say that BRIP1 is the first gene associated with the disease whose protein has a known function.

Medulloblastoma irradiation may impair reading skills in young children

Irradiation therapy for the brain cancer medulloblastoma is more likely to impair IQ and reading skills of younger children than older children even if the dose of radiation is reduced, according to the results of the largest study of its kind, conducted by investigators at St. Jude Children's Research Hospital, Texas Children's Cancer Center (Houston) and Royal Children's Hospital (Melbourne, Australia).

Customized gene chip offers clues to prognosis in cases of neuroblastoma

Rather than covering the entire genome, the microarray focuses on suspect regions of chromosomes for signs of deleted genetic material known to play a role in the cancer.

Customized gene chip will offer clues to prognosis in cases of neuroblastoma

Genetics researchers have developed a customized gene chip to rapidly scan tumor samples for specific DNA changes that offer clues to prognosis in cases of neuroblastoma, a common form of children's cancer.

Discovery may lead to new therapies for leukemia

Researchers from the University of Pennsylvania School of Medicine found that a protein called NF-Ya activates several genes known to regulate the development of hematopoietic stem cells (HSC), or blood-producing stem cells, in bone marrow.

Arf gene prevents excessive growth of blood vessels in the developing eye

A gene better known for its role in preventing cancer also plays a key role in the developing embryo, where the gene prevents excessive growth of blood vessels, according to investigators at St. Jude Children's Research Hospital.

New chemical compound can accelerate stem cell mobilization

The finding has led to the development of a new chemical compound that can accelerate this process (called stem cell mobilization) in mice - which could eventually lead to more efficient stem cell harvesting for human use.

NIPA levels act as switch regulating cell division

Cells control mitosis (cell division) by assembling a biochemical switch to block it or by disassembling the switch to trigger it, according to investigators at St. Jude Children's Research Hospital and the Technical University of Munich.

PGE2 may be a target for Celebrex therapy

A product produced by lung cancer tumors fuels the cells that suppress immune function in patients and may be a target for Celebrex therapy, giving oncologists another weapon to fight cancer, according to a study by researchers at UCLA's Jonsson Cancer Center.

Novel treatment for ovarian cancer

The Tulane University Section of Hematology and Medical Oncology is investigating a novel treatment for ovarian cancer by using intravenous Ontak to deplete harmful cells that inhibit the body's natural immune response to fight cancer. Ovarian cancer is the fifth leading cancer killer of women in the United States.

X-ray crystallography images show how a protein called alpha-actinin performs molecular ballet

As a cell moves forward, physical stress on its skeleton triggers molecular fingers and arms to grasp each other in reinforcing links that stabilize the skeleton, according to images produced by investigators at St. Jude Children's Research Hospital.

Researchers clarifiy role of Notch protein in T-cell development

Researchers at the University of Pennsylvania School of Medicine have recently clarified the role of the Notch protein in T-cell development. T cells are required for many aspects of immunity, including fighting viral infections, providing cancer surveillance, and regulating multiple aspects of the immune response.

New discoveries in treatment for patients with non-Hodgkin's lymphoma

Three scientific studies - each highlighting new discoveries in treatment for patients with non-Hodgkin's lymphoma - were announced at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Thalidomide may be a potent anti-cancer treatment

When people hear "thalidomide," many think "birth defects," however, evidence has come to light that this once-banned drug can be used as a potent anti-cancer treatment.

Female bed-rest study will understand changes to the immune response and decreased resistance to infection in space

A bed-rest study with female participants will help scientists understand changes to the immune response and decreased resistance to infection in space.

Hydroxyurea may prevent complications such as organ damage and stunted growth in treatment of sickle cell disease

Treating babies who have sickle cell disease (SCD) with oral liquid hydroxyurea appears to prevent the onset of long-term complications triggered by this disease, according to results of a preliminary study by investigators at St. Jude Children's Research Hospital.
