| Adapting to stress: Understanding the neurobiology of resilience Posted: 02 Sep 2016 11:22 AM PDT New research examines the way our bodies, specifically our brains, become "stress-resilient." There is a significant variation in the way individuals react and respond to extreme stress and adversity—some individuals develop psychiatric conditions such as posttraumatic stress disorder or major depressive disorder—others recover from stressful experiences without displaying significant symptoms of psychological ill-health, demonstrating stress-resilience. |
| Spiritual meditation plus medication: Best medicine for migraines? Posted: 02 Sep 2016 09:53 AM PDT New research examines whether or not, and to what extent, a combination of spiritual meditation and migraine medication affects analgesic medication usage. |
| Babies born with a low birth weight may be less active in later life Posted: 02 Sep 2016 08:14 AM PDT Individuals who are born with a low birth weight are less likely to be good at sports at school or participate in exercise later on in life. The study used data from the Medical Research Council National Survey for Health and Development, a unique birth cohort that closely monitors a group of people all born in the same week in the UK in March 1946. This particular research involved data from 2,739 of study participants. |
| Luminous heart cells: Jellyfish proteins assist in heart rhythm disorder research Posted: 02 Sep 2016 08:14 AM PDT Cell models from stem cells serve an ever-increasing role in research of cardiac dysfunction. Researchers have succeeded in producing cells which offer new insights into properties of the heart. They installed a molecular sensor into the cells which emits light, and not only makes the cells' electrical activity visible, but also makes it possible for the first time to quickly identify cell types. |
| Virtually reality simplifies early diagnosis of multiple sclerosis and Parkinson's disease Posted: 02 Sep 2016 05:26 AM PDT Scientists are developing an early diagnosis system for neurodegenerative disorders. The system is intended to such diseases as multiple sclerosis, Parkinson's disease and others. The diagnosis system is based on virtual reality (VR) – a person is immersed in a virtual environment to carry out some functional tests. Researchers vary the parameters of the virtual environment and record changes in the person's movements. |
| Solid-state nanopores unravel twisted DNA mystery Posted: 01 Sep 2016 12:23 PM PDT Cancer thrives when mutated cells undergo frequent division. Most anti-cancer drugs work by inserting themselves in between the DNA base pairs that encode our genetic information. This process is known as intercalation, and it can result in subtle changes to the DNA molecule's geometric shape or tertiary structure. These structural changes interfere with the DNA's transcription and a cell's replication process, ultimately resulting in cell death. While intercalating agents used in chemotherapy drugs are highly effective in fighting cancer, they also may kill important cells in the body and lead to other complications such as heart failure. Therefore, researchers are always searching for faster, cheaper and more accurate tools to aid in the design of next-generation anti-cancer drugs with reduced side effects. |
| Chemistry method expedites path to useful molecules for medicine Posted: 01 Sep 2016 12:21 PM PDT A highly efficient method has been developed to convert abundant organic molecules into new medicines. A new report describes a way to convert carbon-hydrogen bonds into nitriles, common components of bioactive molecules used in medicinal and agricultural applications. |
| New method makes building 'one-handed' drugs easier than ever Posted: 01 Sep 2016 12:19 PM PDT Chemists have invented a new technique for constructing one-handed or 'chiral' drug molecules. The new method is already being adopted by pharmaceutical researchers. |
