Bilingual neurons and the secrets of brain disease

Winnerscience: We all know that the neuron is the basic unit of information processing and the building block of the brain and it works together with other neurons and cells throughout the body and it allows us to feel, think, move and breathe. In other words, neuron is an electrically excitable cell that processes and transmits information by electrical and chemical signalling. It is also known as nerve cell. Now a team of researchers from the University of Montreal and McGill University have discovered a type of “cellular bilingualism” – a phenomenon that allows a single neuron to use two different methods of communication to exchange information. An overview of this discovery was published in the Nature Reviews Neuroscience journal (Neuroscience is the archetypal multidisciplinary science encompassing a variety of fields that share the common goal of attempting to provide a complete understanding of the structure and function of the central nervous system. A series of advances in molecular, developmental and cognitive neuroscience, stimulated by the advent of powerful new experimental techniques and theoretical approaches, have now rendered some of the most enduring neurobiological questions increasingly tractable. This explosion of knowledge has in turn created a need for new tools to efficiently organize and communicate this information. Nature Reviews Neuroscience covers the breadth and depth of modern neuroscience by providing an authoritative, accessible, topical, and engaging first port of call for scientists who are interested in all aspect of neuroscience — from molecules to the mind. It has a very high 2009 impact factor of 26.483). Continue reading “Bilingual neurons and the secrets of brain disease”

High blood pressure in older adults is linked with steeper decline in walking speeds

Note from winnerscience: Researchers have found a link between high blood pressure and a greater drop in average walking speeds in older adults, according to results from a new National Institutes of Health-funded study. The drop seems to occur even in study participants whose high blood pressure is successfully treated. Drastic changes in walking speed can impact a older adult ability to remain independent and indicate possible health problems. The study will appear in the March edition of the Journal of the American Geriatric Society (The Journal of the American Geriatrics Society is a comprehensive and reliable source of monthly research and information about common diseases and disorders of older adults. It is published by Wiley-Blackwell and it has 2009 impact factor of 3.656. Start reading the Journal of the American Geriatrics Society now and you’ll enjoy the most current randomized clinical trials results, the best editorials from international experts and the reviews that wrap up recent outcomes in convenient, easy-to-read articles). Let us see how they reached into this conclusion: Continue reading “High blood pressure in older adults is linked with steeper decline in walking speeds”

Artesunate More Effective Than Quinine Against Severe Malaria

Note from Winnerscience: We all must be very much aware about the common medicine “Quinine” used to treat the severe malaria. Severe malaria occurs when the disease affects the function of vital organs. It is associated with rarer cerebral malaria, which affects the brain and can lead to long-term disability. More than a million people die each year from severe malaria, the majority in Sub-Saharan Africa. But now the researchers found another medicine “artesunate” which is more effective than “Quinine” in treatment of severe Malaria. Let us discuss how the researchers came to this inclusion: Continue reading “Artesunate More Effective Than Quinine Against Severe Malaria”

Tamoxifen Can Save Lives And Medical Costs

Note from Winnerscience: Hi friends, most of us may know about the side effects of medicine “Tamoxifen” taken by women as a preventive measure against breast cancer. For the information of our readers, breast cancer is caused due to the certain changes in DNA that results in normal breast cells to become cancer. (DNA is the chemical in each of our cells that makes up our genes — the instructions for how our cells work). Some inherited DNA changes called mutations can increase the risk for developing cancer and cause the cancers that run in some families. But most breast cancer DNA changes happen in single breast cells during a woman’s life rather than having been inherited. So far, the causes of most of the DNA mutations that could lead to breast cancer are not known. Continue reading “Tamoxifen Can Save Lives And Medical Costs”

Influence of Sunlight on the breakdown of medicines in the body

Note from Winnerscience: Dear friends, we all know that sunlight is very essential for our body especially for the bones. Now in a new study conducted by the researchers at the Swedish medical university Karolinska Institute has proved that the sunlight can influence the breakdown of medicines in the body. Therefore, the breakdown of medicines can vary with the seasons that are it will be different in winters than the summers. Let us elaborate it further: Continue reading “Influence of Sunlight on the breakdown of medicines in the body”
