08/12/2013 — 12/12/2013, Malaria infects over 250 million worldwide and kills an estimated 660,000 annually -- mostly African children. Current anti-malaria efforts are largely focused on advanced science and vaccine development. But experts gathering this week at the Hebrew university of Jerusalem believe a parallel...

Researchers at the University of Calgary's Hotchkiss Brain Institute have made a discovery that could lead to better treatment for patients suffering from brain cancer. Researchers looked at human brain tumor samples and discovered that specialized immune cells in brain tumor patients are...

Researchers from the Monell Center and collaborating institutions have found that as much as 30 percent of the large array of human olfactory receptor differs between any two individuals. This substantial variation is in turn reflected by variability in how each person perceives odors. Fuente :...

A new study has found that bed bugs may be less susceptible to freezing temperatures than previously reported, but given adequate time and cold enough temperatures, freezing can still be an effective means of control. Fuente : http://www.eurekalert.org/pub_releases/2013-12/eso...

New research presented today during the 55th American Society of Hematology Annual Meeting and Exposition in New Orleans uncovers several important insights into the pathophysiology of sickle cell disease and thalassemia that may soon translate into the development of better, more targeted...

Adding bortezomib (Velcade) to standard preventive therapy for graft-versus-host-disease results in improved outcomes for patients receiving stem-cell transplants from mismatched and unrelated donors, according to researchers from Dana-Farber Cancer Institute. Fuente :...

The energy needed to change the magnetic orientation of a single atom -- which determines its magnetic stability and therefore its usefulness in a variety of future device applications -- can be modified by varying the atom's electrical coupling to nearby metals. Fuente :...

In our youth we are strong and healthy and then we weaken and die -- that's probably how most would describe what aging is all about. But, in nature, the phenomenon of aging shows an unexpected diversity of patterns and is altogether rather strange, conclude researchers from The University of...

Hematology researchers have manipulated key biological events in adult blood cells to produce a form of hemoglobin normally absent after the newborn period. Because fetal hemoglobin is unaffected by the genetic defect in sickle cell disease, these cell culture findings may open the door to a new...

There is more than meets the eye following even a mild traumatic brain injury. While the brain may appear to be intact, new findings reported in Nature suggest that the brain's protective coverings may feel the brunt of the impact. Fuente : http://www.eurekalert.org/pub_releases/2013-12/nio...

Imágenes de cuerpos torturados y caras poco reconocibles, víctimas de linchamientos de enardecidos pobladores, sacuden cada poco a la sociedad de Bolivia. Un fenómeno de ajusticiamiento sumario que nada tiene que ver con la justicia comunitaria, aunque los victimarios se arropen en ella. Estadísticas de la Defensoría del Pueblo...

Certain genetic alterations to the PAX gene family may be responsible for survival disparities seen between African-American and non-Latino white men with head and neck cancer, according to results presented here at the Sixth AACR Conference on the Science of Cancer Health Disparities in...

Large numbers of marine fossils have been discovered for the first time in the limestone of the upper part of the Linxi Formation in the Guandi section, Linxi County, eastern Inner Mongolia. These marine fossils provide the first evidence that the Xingmeng area was still a marine or mainly marine...

A team of scientists at Johns Hopkins and in Texas has identified a handful of genetic mutations in black Americans, in addition to some chemical alterations affecting gene activity, which may help explain why the death rate among African-Americans from the most common form of head and neck cancer...

Nearly 90 percent of children and adults with a highly aggressive form of acute lymphoblastic leukemia showed no evidence of cancer after receiving a novel, personalized cell therapy that reprograms a patient's immune system. In pilot studies of bioengineered T cells that attack leukemia, 24 of 27...

A series of advancements in genetically engineered cell therapies demonstrate early efficacy and safety in patients with blood disorders for whom standard treatments have been unsuccessful, according to data showcased today during the 55th American Society of Hematology Annual Meeting and...

Hematopoietic stem cell transplantation, once considered an effective yet risky alternative to drug therapy for blood cancer, has become more accessible and successful in a wide range of patients as a result of major advances in transplant strategies and technologies. Several studies representing...

Patients with myelodysplastic syndromes who were as old as 74 fared as well with stem cell transplantation as did patients in the 60-to-65 age range, according to a study from Dana-Farber Cancer Institute presented at the annual meeting of the American Society of Hematology. Fuente :...

Some babies diagnosed with and treated for a bone marrow failure disorder, called Diamond Blackfan Anemia, may actually be affected by a very rare anemia syndrome that has a different disease course and treatment, say scientists from Dana-Farber/Boston Children's Cancer and Blood Disorders Center....

Researchers reported promising outcomes data for the first group of boys with X-linked severe combined immunodeficiency syndrome, a fatal genetic immunodeficiency also known as "bubble boy" disease, who were treated in an international clinical study of a new form of gene therapy. The mechanism...

Three and a half years after beginning a clinical trial which demonstrated the first successful and sustained use of genetically engineered T cells to fight leukemia, a research team from the University of Pennsylvania will announce the latest data on 59 adults and children with advanced blood...

Una encuesta realizada en Irán tras la elección del presidente Hasán Ruhaní indica que la mayoría se opone a que su país intervenga en Siria e Iraq y cree que el gobierno busca fabricar armas nucleares, aunque sostenga lo contrario.

Researchers are looking for new ways to fight malaria through mosquito control. In 2011, 1,925 malaria cases were reported in the U.S., according to the Centers for Disease Control and Prevention (CDC). This number is the highest seen since 1971 and represents a 48 percent increase from 2008. The majority of malaria infections...
