Breast Cancer Breakthrough

Recently, researchers at Lawrence Berkeley National Laboratory have developed the first clinically-relevant mouse model of human breast cancer, as part of successfully expressing functional estrogen receptor positive (ER+) adenocarcinomas.  The tumors that have been generated in this system bear a strong resemblance to the class of tumors that can be found among most women with breast cancer, in particular those whose cancer proves treatment-resistant.  Such a model could prove itself a powerful tool for testing therapies for aggressive E+ breast cancers, as well as for...

CJD and Alzheimer’s?

According to new research, the brains of Creutzfeldt-Jakob disease (CJD) victims show evidence of Alzheimer’s pathology.  However, neuroscientists have dismissed concerns that people can “catch” Alzheimer’s by becoming infected with the “seeds” of the condition through surgery with contaminated instruments or blood transfusions.  The study, published in Nature last week, reported autopsy results from the brains of eight people between 36 and 51 years old who died of CJD after receiving contaminated growth hormone injections.  In four subjects, there was evidence of...

Sleep Laterally

According to researchers at Stony Brook University, sleeping in the lateral position, as opposed to on one’s back or stomach, could help more effectively remove brain waste and be an important practice to help reduce the chances of developing such neurological diseases as Alzheimer’s and Parkinson’s.  By imaging the brain’s glymphatic pathway with dynamic contrast MRI, Stony Brook University researchers discovered that a lateral sleeping position, the most common among humans and animals, is the best to most efficiently remove waste from the brain.  Brain waste chemicals...

3D Printed Cadavers?

The onset of 3D printing has truly revolutionized numerous fields, such as fashion, prosthetics and human organs, although medical educators have been a little more skeptical when it comes to artificial cadavers.  The 3D Printed Anatomy Series, to be sold later this year by Paul McMenamin, the director of Monash University’s Centre for Human Anatomy Education, contains life-sized replicas of all parts needed to teach the anatomy of the limbs, chest, abdomen, head and neck.  While this may replace plastic models with higher resolution models, its place in medical schools...

Ebola Test Kit Developed

The outbreak of Ebola in West Africa has led to German researchers developing a fast, cheap and accurate test to be performed in patient-care settings without a centralized medical laboratory.  In the parts of West Africa hit hardest by Ebola, a lack of electricity, reliable cold storage and diagnostic equipment pose as major obstacles for technicians trying to test patients for Ebola.  However, a new test developed by researchers at the German Primate Center (DPZ) cuts the time to answer an Ebola diagnosis to just 15 minutes.  This method requires no electricity, and is...
