Neuroscientists use snail research to help explain ‘chemo brain’

In an effort to solve this mystery, neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) conducted an experiment in an animal memory model and their results point to a possible explanation. Findings appeared in The Journal of Neuroscience. In the study involving a sea snail that shares many of the same memory mechanisms as humans and a drug used to treat a variety of cancers, the scientists identified memory mechanisms blocked by the drug. …

Help explain ‘chemo brain’ through snail research

In an effort to solve this mystery, neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) conducted an experiment in an animal memory model and their results point to a possible explanation. Findings appeared in The Journal of Neuroscience. In the study involving a sea snail that shares many of the same memory mechanisms as humans and a drug used to treat a variety of cancers, the scientists identified memory mechanisms blocked by the drug. Then, they were able to counteract or unblock the mechanisms by administering another agent. …

New educational modules harness power of e-learning for pancreatic cancer education

The ePOSSOM endeavour was jointly developed by ecancer and the Severn Postgraduate School of Surgery, where surgical trainees led by Miss Katrina Butcher developed the content of the modules, providing key educational information for other surgical trainees and healthcare professionals. “ePOSSOM creates innovative e-learning material for audiences across the world, allowing each learner access to complex evidence-based medicine, wherever their learning environment allows them,” Miss Butcher writes in the accompanying editorial. These modules follow the UK ISCP (Intercollegiate Surgical Curriculum Programme) Curriculum, and aim to be a concise, up-to-date best evidence resource, for either new learning or revision. Experts from across the UK have contributed to and peer-reviewed the modules to ensure that the content is of the highest scientific quality — and poised on the frontier of pancreatic cancer knowledge. …

Partially blocking blood vessels’ energy source may stop cancer growth, blindness, other conditions

"Our findings reveal a new strategy to block blood vessel growth in various pathological conditions by depriving them of energy and building blocks necessary for growth," says senior author Dr. Peter Carmeliet of the University of Leuven and the Vesalius Research Center, VIB in Belgium. While current strategies to thwart pathological blood vessel formation focus primarily on inhibiting vascular endothelial growth factor (VEGF), this latest research centers around blocking glycolysis, the process that endothelial cells rely on for generating most of the energy they need to multiply and migrate. …

New study suggests low vitamin D causes damage to brain

In addition to being essential for maintaining bone health, newer evidence shows that vitamin D serves important roles in other organs and tissue, including the brain. Published in Free Radical Biology and Medicine, the UK study showed that middle-aged rats that were fed a diet low in vitamin D for several months developed free radical damage to the brain, and many different brain proteins were damaged as identified by redox proteomics. These rats also showed a significant decrease in cognitive performance on tests of learning and memory. "Given that vitamin D deficiency is especially widespread among the elderly, we investigated how during aging from middle-age to old-age how low vitamin D affected the oxidative status of the brain," said lead author on the paper Allan Butterfield, professor in the UK Department of Chemistry, director of the Center of Membrane Sciences, faculty of Sanders-Brown Center on Aging, and director of the Free Radical Biology in Cancer Core of the Markey Cancer Center. …

Foods that may prevent Type-2 diabetes in children

As our lives have become more fast-paced, the way we feed our children has also changed. Running from one activity to the next can make it easy to justify the convenience of quick food, even if it means not providing the best nourishment. Research has shown that the top sources of energy for children between the ages of two and 18 come from grain desserts, pizza and soda - with nearly 40% of their consumed energy coming in the form of empty calories.  The mentality that a quick bite is better than nothing may be ruining our children’s health. Learning disorders, fatigue, depression, obesity and diabetes among children is becoming the norm rather than the exception. However, Type 2 diabetes can be prevented and even reversed with the right diet.  One of the best gifts a parent can give a child is a strong nutritional start and healthy eating habits. Children need nutrient dense foods to provide them with adequate energy to grow and play. The easiest way to do this is by sticking with fresh food and avoiding anything that can sit on a shelf without decomposing for years. From a child’s first bite of food, their tastes begin to form. Feeding them salty and sugary foods and juice will create cravings for more. Instead, offer a variety of different flavors and create a natural desire for fresh foods. Bone broth  Real bone broth made from chicken, beef, fish or other bones is simple to make and full of minerals that can boost immunity. Aside from healthy minerals, bone broth is rich in gelatin and glycosaminoglycan which promote the healthy development of bone and dental structures. Bone broth can easily be incorporated into soups, casseroles, stews and sauces – and can even be frozen in ice cube trays for reuse. Saturated fats Children need saturated fats and cholesterol in order to develop a healthy brain and nervous system. They are also vital for developing strong teeth and bones, healthy tissues and strong immune systems. The key is to buy the highest quality you can afford. Meats and eggs from pasture-raised animals are significantly higher in vital nutrients such as Omega-3 fatty acids and are free of antibiotics and hormones. Buying produce from local farms can guarantee freshness while keeping costs down.  Vegan sources of saturated fat also provide amazing health benefits and are usually kid-friendly. Olive and coconut oil are great for cooking with and nuts and avocado make great nutrient-dense snacks that can keep children from craving junk food. Fermented foods From pickles to yogurt, finding a few fermented foods to add to your child’s diet can help keep them healthy. Fermented foods are rich in probiotics, which increase healthy gut bacteria, and have been linked to stronger immunity, better digestion and fewer allergies.  Since fermented foods come in so many different flavor and texture profiles, finding at least one that your child enjoys should be relatively easy. Almost any vegetable can be pickled and sauerkraut, kimchi and pickles can be refrigerated for long periods of time. Organic, plain yogurt and kefir are great additions to smoothies and can make a quick breakfast when you’re on the go. Children have a natural drive to be active and get the right kind of exercise, so take advantage of it. With recess being shortened and physical education being cut out of many schools, having the opportunity to exercise at home is crucial.  Turn your back yard into a mini gym by providing heavy things to play with, obstacles to jump around and sand for digging in. If you don’t have a yard, make it a daily habit to do an outdoor activity together such as going for a walk, riding a bike or kicking a soccer ball back and forth. Keep the exercise fun and enjoy the bonding time.Jacqueline Banks is a certified holistic health counselor and busy mother. & Her focus is on helping other busy moms in all stages of motherhood keep themselves and their little ones healthy and happy. & She uses natural and organic solutions to solve individual health problems and promote clean living.

Could eating less save your brain? Study shows reducing calories delays nerve cell loss

Calorie restriction may not always be fun, but cutting back has benefits beyond even weight loss. Studies have shown that eating less can help slow aging, prolong life and even decrease the effects of diseases like Alzheimer’s in a variety of organisms. Based on this knowledge, a group of researchers from the Massachusetts Institute of Technology (MIT) decided to dig further and ask: Could calorie restriction also delay nerve cell loss in the brain – and the changes in learning and memory that go along with it? “We reasoned – and other folks reasoned – that because cognitive decline and neurodegeneration are characteristics of the aging process, that calorie restriction might also work in the brain to slow neurodegeneration,” lead study author, Dr. Johannes Gräff from the Picower Institute for Learning and Memory at MIT, and Howard Hughes Medical Institute, told FoxNews.com. Gräff and his colleagues tested their theory using a group of mice engineered to experience rapid neurodegeneration. Researchers decreased half of the mice’s calorie intake by 30 percent and kept the remaining mice on a normal diet. After three months, researchers tested the learning and memory skills in each group of mice, expecting to see a decline in both cognitive areas. However, while the mice eating normally showed evidence of significant learning and memory deficits related to nerve cell loss, the calorie-restricted mice showed no defecits in their learning or memory skills. “That was one of the first experiments we did, and that was quite promising and cool that it worked,” Gräff said. In the next phase of the study, researchers took a more in-depth look at the brains of both groups of mice. “What we further did was to look through the brains to check the extent or amount of neurodegeneration, and what we found was that neurodegeneration had been slowed down by calorie restriction,” Gräff said. Researchers were curious if reduced neurodegeneration could still be achieved by utilizing proteins activated during calorie restriction – without actually restricting calories. Eventually, they targeted an enzyme called Sirtuin 1 (SIRT1). “This protein is one candidate that has been known to be more abundantly expressed as a result of calorie restriction in our tissues,” Gräff said. The scientists then gave a separate group of mice, also engineered to experience rapid neurodegeneration, a pharmacological dose of SIRT1, without restricting their calorie intake. These mice experienced the same effects as the calorie-restricted mice, showing slower rates of nerve cell loss and no learning or memory deficits after a three-month period. Graff noted that more research needed to be done in this area, and he hopes to further explore the relationship between calorie restriction, SIRT1 and neurodegeneration. “We have the choice – (to look into how) to reduce calorie intake in order to slow onset of neurodegeneration, or we look to this pharmacological activator (to do the same thing),” Gräff said. “Do you want to engage more into reducing caloric intake or revert to pharmacological means for the same effect?” This study is published in the May 22nd issue of The Journal of Neuroscience.source : http://www.foxnews.com/health/2013/05/22/could-eating-less-save-your-brain-study-shows-reducing-calorie-intake-delays/
