Two Studies Reveal Important Genetic Insights Into The Development Of Non-Hodgkin Lymphoma (NHL)
7/02/2013
Scientists at the Genome Institute of Singapore (GIS) recently led in two studies that revealed important genetic insights into the development of non-Hodgkin lymphoma (NHL). NHLs are some of the most common blood cancers and include any kind of lymphoma1 except Hodgkin's lymphomas...
Measuring The Thermal Signatures Of Single Cells And Assessing Their Biological Activity
7/02/2013
To the ancients, probing the philosophical question of how to distinguish the living from the dead centered on the "mystery of the vital heat." To modern microbiology, this question was always less mysterious than it was annoying - researchers have known that biological processes should produce thermal signatures, even within single cells, but nobody ever knew how to measure them...
Cardiac Hormone-Related Inflammatory Pathway Linked To Tumor Growth
7/02/2013
A cardiac hormone signaling receptor abundantly expressed both in inflamed tissues and cancers appears to recruit stem cells that form the blood vessels needed to feed tumor growth, reports a new study by scientists at the University of South Florida Nanomedicine Research Center...
Cells rely on an intricate network of signaling pathways to govern a number of processes ranging from tissue repair to programmed cell death. De-regulation of signaling pathways is a hallmark of cancer and responsible for driving tumor formation...
Risk Of Breast Cancer Recurrence After Tamoxifen Treatment Predicted By Biomarker
7/02/2013
A biomarker reflecting expression levels of two genes in tumor tissue may be able to predict which women treated for estrogen-receptor (ER)-positive breast cancer should receive a second estrogen-blocking medication after completing tamoxifen treatment...
The Importance Of Preventing Iron Deficiency
7/02/2013
Iron deficiency is a worldwide problem, especially in developing countries and among infants and pregnant women. In infancy, iron deficiency is associated with poorer cognitive, motor, and social-emotional outcomes. In a new study scheduled for publication in The Journal of Pediatrics, researchers report on a 25-year follow-up of infants studied in Costa Rica for iron deficiency...

Engineers from Queen Mary, University of London have developed the world's most precise computer simulation of how red blood cells might travel around the body to help doctors treat people with serious circulatory problems...
Surgeons Report Melanoma Recurs After 10 Years In More Than 6 Percent Of Patients
7/01/2013
Recurrence of melanoma skin cancer 10 or more years after initial treatment is more common than previously thought, occurring in more than one in 20 patients. However, according to a new study, these patients tend to live longer after their cancer returns than patients whose melanoma recurs in the first three years...
