New Measurements to Guide Radiation Therapy

When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. Ionizing radiation used for cancer treatment includes gamma rays, X-rays and energetic particles. The electrons produced by this process, known as secondary electrons, can themselves go on to wreak further havoc, causing even more dramatic changes. This week in The Journal of Chemical Physics, investigators report studies of the impact of secondary electrons on a model of DNA.

Researchers Isolate Biting, Non-Biting Genes in Pitcher Plant Mosquitoes

Understanding that divergence, University of Notre Dame researchers say, is a starting point to determining whether there are non-biting genes in other species that could be manipulated in order to reduce transmission of vector-borne diseases.

The Not So Sweet Side of Christmas

A new video by the University of Warwick highlights a bitter side to our sugar consumption at Christmas. The short film highlights how excessive consumption of sugar can affect our health – and how the sugar trade in the past and today has caused inequality and bloodshed.Today Britons eat too much sugar, on average 10 per cent of our daily calories come from sugar which is equivalent to 60 g per day; however WHO guidelines state that adults should eat no more than of 30g of sugar a day which is just five per cent of our daily calorific intake.

Study Sheds Light on Rarity of Disease-Causing IGF Mutations

Peter Rotwein, M.D., was recently spotlighted by the American Society for Biochemistry and Molecular Biology (ASBMB) for a study he conducted on insulin-like growth factors (IGFs), a family of proteins that are crucial in early human growth and development. IGF mutations have been tied to dire health problems, like growth failure, intellectual deficiencies, and other developmental abnormalities.

Molecular Signature of “Trailblazer” Neural Crest Cells Gives Insight Into Development and Cancer

SIMR_Press_Release_14Dec_2017_PMK.jpg

In a study published online in the journal eLife, the researchers identified a molecular signature of approximately 1300 genes differentially expressed in an aggressive subset of migrating neural crest cells termed as “trailblazers” in a vertebrate model system of development. These genes appear to play a critical role in migration and may be part of a broader molecular signature of cell invasion in a number of phenomena.

Flower or Flesh? Genetics Explain Mosquito Preference

Researchers have found genetic explanations for why most mosquitoes in one species favor nectar over blood. This work could one day lead to strategies to prevent mosquito-borne illness.

UCLA scientists have developed a new strategy to efficiently isolate, mature and transplant skeletal muscle cells created from human pluripotent stem cells, which can produce all cell types of the body. The findings are a major step towards developing a stem cell replacement therapy for muscle diseases including Duchenne Muscular Dystrophy.

Scientists Pinpoint Gene to Blame for Poorer Survival Rate in Early-Onset Breast Cancer Patients

A new study led by scientists at the University of Southampton has found that inherited variation in a particular gene may be to blame for the lower survival rate of patients diagnosed with early-onset breast cancer.

Un estudio de Mayo Clinic descubrió que entre los obstáculos para que los pacientes se sometan al trasplante de células madre como parte del tratamiento para el mieloma múltiple están la educación, el seguro de salud y el acceso a atención médica en una institución con gran volumen de pacientes.
