The following articles were added on December 20, 2009 and complete our reviews for 2008...

Small Molecules, Large Effect: How Cancer Cells Ensure Their Survival (December 31, 2008) -- Scientists have identified a molecular mechanism used by cancer cells to "defend" themselves against chemotherapeutics in an attempt to ensure their own survival. Both the messenger substance Nitric Oxide (nitrogen monoxide) and the protein survivin play a role in this. ... >

Blood Sugar Linked To Normal Cognitive Aging (December 31, 2008) -- Maintaining blood sugar levels, even in the absence of disease, may be an important strategy for preserving cognitive health, suggests a new study. The findings suggest that exercising to improve blood sugar levels could be a way for some people to stave off the normal cognitive decline that comes with age. ... >

Another Reason To Avoid High-fat Diet: It Can Disrupt Our Biological Clock, Say Researchers (December 31, 2008) -- Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms -- everyone's 24-hour biological clock, researchers have shown. ... >

“The biological clock regulates the expression and/or activity of enzymes and hormones involved in metabolism, and disturbance of the clock can lead to such phenomena as hormone imbalance, obesity, psychological and sleep disorders and cancer.”

Women Double Fruit, Veggie Intake With Switch To Mediterranean Diet Plan (December 31, 2008) -- Women more than doubled their fruit and vegetable intakes and dramatically increased their consumption of 'good' fats when they were counseled by registered dietitians and provided with a list of guidelines on the amount of certain foods they should eat each day. ... >

Editors Note: Hemp Nuts would be a logical choice to provide adequate amounts of 'good' (essential) fats and essential proteins.

Moderate Drinking Can Reduce Risks Of Alzheimer's Dementia And Cognitive Decline, Analysis Suggests (December 31, 2008) -- Moderate drinkers often have lower risks of Alzheimer's disease and other cognitive loss, according to researchers who reviewed 44 studies. In more than half of the studies, published since the 1990s, moderate drinkers of wine, beer and liquor had lower dementia risks than nondrinkers. ... >

Common Food Additive Found To Increase Risk And Speed Spread Of Cancer (December 30, 2008) -- New research in an animal model suggests that a diet high in inorganic phosphates, which are found in a variety of processed foods including meats, cheeses, beverages and bakery products, might speed growth of lung cancer tumors and may even contribute to the development of those tumors in individuals predisposed to the disease. ... >

“Lung cancer is the number one cause of cancer deaths in the world.” "Our results clearly demonstrated that the diet higher in inorganic phosphates caused an increase in the size of the tumors and stimulated growth of the tumors," Dr. Cho said.

Editors Note: It would be logical to assume that inorganic phosphates contribute to all forms of cancer, not just lung cancer.

Both Major Theories About Human Cellular Aging Supported By New Research (December 30, 2008) -- Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells. ... >

Berry Compound Reduces Aging Effect (December 30, 2008) -- Aged laboratory animals that ate a diet rich in the berry and grape compound pterostilbene performed better than those in a group that did not eat the enriched diet, scientists with the Agricultural Research Service have reported. Pterostilbene reversed measurable negative effects of aging on brain function and behavioral performance. ... >

Breast Cancer: Diet High In Vegetables, Fruit And Fiber May Cut Risk Of Cancer Recurrence In Women Without Hot Flashes (December 30, 2008) -- A secondary analysis of a large, multicenter clinical trial has shown that a diet loaded with fruits, vegetables and fiber and somewhat lower in fat compared to standard federal dietary recommendations cuts the risk of recurrence in a subgroup of early-stage breast cancer survivors -- women who didn't have hot flashes -- by approximately 31 percent. These patients typically have higher recurrence and lower survival rates than breast cancer patients who have hot flashes. ... >

How Certain Vegetables Combat Cancer (December 29, 2008) -- Women should go for the broccoli when the relish tray comes around during holiday celebrations this season. ... >

Nutritious Fast-food Kids' Meals Are Scarce, Researchers Find (December 28, 2008) -- Only three percent of kids' meals served at fast-food restaurants met federal dietary guidelines in the first study to examine the nutrient quality of such meals in a major US metropolitan market. The small percentage of meals that did meet dietary guidelines included fruit as a side dish and milk, and nearly all were deli-sandwich meals. ... >

Primary Cilium As Cellular 'GPS System' Crucial To Wound Repair (December 25, 2008) -- The primary cilium, the solitary, antenna-like structure that studs the outer surfaces of virtually all human cells, orients cells to move in the right direction and at the speed needed to heal wounds, much like a global positioning system helps ships navigate to their destinations. ... >

Peripheral Artery Disease: Pain When Walking Can Be Reduced With Moderate Exercise, Study Suggests (December 25, 2008) -- You probably know that poor diet and lack of exercise can lead to dangerous deposits of fatty plaques in arteries. But it is not just the heart that is affected – blood flow can be blocked to the legs too, leading to pain when walking, immobility and even in extreme cases, amputation. Approximately 20% of us will suffer from this peripheral artery disease (PAD) once we are 65 or over, and with risk factors including smoking, diabetes, obesity and high blood pressure it is on the rise. ... >

Protein Helps Build Muscle Mass: Possible Treatment For Muscle Wasting Disorders (December 24, 2008) -- Researchers are reporting how to build muscle mass with the protein FHL1. The protein partners with and activates the transcription factor, NFATc1. Encouraging this partnership might provide a possible treatment for muscle wasting disorders. ... >

Probiotics May Help People Taking Antibiotics (December 24, 2008) -- Up to one in five people on antibiotics stop taking their full course of antibiotic therapy due to diarrhea. Physicians could help patients avoid this problem by prescribing probiotics, according to a new study. ... >

Common Infant Virus May Trigger Type 1 Diabetes (December 22, 2008) -- Human parechovirus is a harmless virus which is encountered by most infants and displays few symptoms. Suspected of triggering type 1 diabetes in susceptible people, research methods need to take this 'silent' virus into consideration. ... >

Breakthrough In Understanding Development Of Type 1 Diabetes (December 19, 2008) -- Finnish scientists have reported a breakthrough in understanding the development of type 1 diabetes. They discovered disturbances in lipid and amino acid metabolism in children who later progressed to type 1 diabetes, also known as juvenile diabetes. The alterations preceded the autoimmune response by months to years. The study may prompt new approaches for prediction and prevention of type 1 diabetes in pre-autoimmune phase of the disease. ... >

Lean Muscle Mass Helps Even Obese Patients Battle Cancer (December 18, 2008) -- Lean muscle-mass may give even obese people an advantage in battling cancer, a new study shows. ... >

Cellular Stress Causes Fatty Liver Disease In Mice (December 16, 2008) -- Researchers have discovered a direct link between disruption of a critical cellular housekeeping process and fatty liver disease, a condition that causes fat to accumulate in the liver. The findings might open new avenues for understanding and perhaps treating fatty liver disease, which is the most common form of liver disease in the Western world. ... >

Editors note: The Hemp Nut and/or Hemp Protein diet may be an answer to protein miss-folding and we encourage the authors to study the effects that “Globular Proteins” found in Hemp may have. “Protein folding, which occurs in a cellular compartment called the endoplasmic reticulum (ER), is a vital cellular process because proteins must be correctly folded into defined three-dimensional shapes in order to function.”

How Mutations Are Transmitted From One Generation To The Next (December 15, 2008) -- A fundamental process in the transmission of genes from mother to child has been identified. The new study identifies a mechanism that plays a key role in how mutations are transmitted from one generation to the next, providing unprecedented insight into metabolic diseases. ... >

Mathematical Model Gives Clearer Picture Of Physics Of Cells, Organelles (December 15, 2008) -- Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula. Over the years, scientists have made much progress in understanding the biomolecular details of how these organelles function within cells, but understanding the actual physical forces that maintain the structures of these organelles' membranes continues to be a challenge. ... >

Understanding Of Bone Marrow Stem Cell Niche Expanded (December 15, 2008) -- Scientists have identified the precise location of the bone marrow stem cell niche. The findings were published in Nature. ... >

Broccoli Compound Targets Key Enzyme In Late-stage Cancer (December 14, 2008) -- Broccoli and other cruciferous vegetables have long been known to have anti-cancer benefits, and researchers have now found out why. One well-known anti-cancer chemical in broccoli, indole-3-carbinol, was found to inhibit the enzyme elastase, which is found at high levels in late-stage breast and prostate cancers. The discovery of this target will help to design better anti-cancer drugs and to target treatment to specific types of cancer, including late-stage breast and prostate cancers. ... >

Fructose Metabolism More Complicated Than Was Thought (December 11, 2008) -- A new study suggests that we may pay a price for ingesting too much fructose. Chances are you consume quite a bit of fructose. Most Americans do --- in refined sugars such as sucrose or table sugar (which is half fructose) and in high-fructose corn syrup, used in products as diverse as soft drinks, protein bars, and fruit juice. Dietary fructose affects a wide range of genes in the liver that had not previously been identified. ... >

Editors note: The authors fail to mention that candy, commercial breads, breakfast cereals and bakery's often use a lot of fructose and/or sucrose in their goods.

Sugar Can Be Addictive: Animal Studies Show Sugar Dependence (December 11, 2008) -- Scientists have demonstrated that sugar can be an addictive substance, wielding its power over the brains of lab animals in a manner similar to many drugs of abuse. Researchers found profound behavioral changes in rats that, through experimental conditions, have been trained to become dependent on high doses of sugar. Lab animals that were denied sugar for a prolonged period after learning to binge worked harder to get it when it was reintroduced to them. They consumed more sugar than they ever had before, suggesting craving and relapse behavior. ... >

38 Percent Of Adults And 12 Percent Of Children Use Complementary And Alternative Medicine, Government Survey Shows (December 11, 2008) -- Approximately 38 percent of adults in the United States aged 18 years and over and nearly 12 percent of U.S. children aged 17 years and under use some form of complementary and alternative medicine, according to a new nationwide government survey. ... >

'Border Patrol Agents' Identified In The Gut (December 10, 2008) -- Researchers have shown in mice how and under what circumstances the gut activates its defensive mechanisms to prevent illness. ... >

Eye Disorders Linked To Statin Drug Use In Some Patients (December 10, 2008) -- Statin medications are used to lower patients' cholesterol levels, thus helping prevent coronary heart disease, stroke and other deaths related to high cholesterol levels. Statin use has grown rapidly since 1992, and seems likely to increase in light of the recent, widely-reported Jupiter Study on statin benefits in patients with low cholesterol but elevated C-reactive protein. ... >

Apoptosis Inhibitors Prevent Not Only Cell Death, But Also Play A Role In Cell Migration (December 10, 2008) -- Many of the cancer drugs currently undergoing clinical trials target apoptosis inhibitors (IAPs), since if the levels of IAPs are reduced, tumor cells will be destroyed by the body's own self-protecting mechanism or by the chemotherapeutic drugs. However, researchers have recently discovered that IAPs also have another life: they control cell migration. ... >

According to the researchers, drugs to target IAPs should therefore only be used with caution in future.

Food Can Affect A Cell In The Same Way Hormones Do (December 9, 2008) -- Researchers have discovered an important new mechanism with which cells can detect nutrients. This happens in the same way - and with the same effects – as when cells receive a message from a hormone. This finding can teach us more about how food affects our body; and, furthermore, it can form the basis for new candidate targets for medicines. ... >

Progression Of Retinal Disease Linked To Cell Starvation (December 9, 2008) -- A new study illuminates an incurable eye disease that afflicts approximately 100,000 Americans. Your retina contains two types of cells that send signals when they detect light: rods and cones. In patients with Retinitis Pigmentosa, first the rods, then the cones die, leading to blindness. While most cases of the disease are due to mutations in rod-specific genes, cones don't escape death. New data suggest that the cones die because they are starving. ... >

Antibiotics: Single Largest Class Of Drugs Causing Liver Injury (December 8, 2008) -- Antibiotics are the single largest class of agents that cause idiosyncratic drug-induced liver injury, reports a new study in Gastroenterology. DILI is the most common cause of death from acute liver failure and accounts for approximately 13 percent of cases of acute liver failure in the US. It is caused by a wide variety of prescription and nonprescription medications, nutritional supplements and herbals. ... >

Shared Features Of Human Gut Microbial Communities: Variations Linked To Obesity (December 8, 2008) -- Researchers have catalogued the microbial species in the guts of lean and obese female twins and their mothers, finding that each individual carries a unique collection of bacteria, although the communities are more similar among family members. However, when the scientists looked closer, they found the various collections of bacterial species carried a common set of genes that performed key functions to complement those performed by our human genes. ... >

Escape Cancer, But Age Sooner? The Dark Side Of The Tumor Suppressing Process (December 5, 2008) -- Cells shut down and stop dividing when their DNA is damaged so as to prevent damaged DNA from leading to unregulated cell division and therefore cancer. However, a new study has found that when these cells shut down they also spew proteins into their surrounding environment. This causes inflammation and sets up conditions that support the development of age-related diseases including, ironically, cancer. ... >

Calcium And Vitamin D May Not Be The Only Protection Against Bone Loss (December 4, 2008) -- Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study. The study found that increasing the alkali content of the diet, with a pill or through a diet rich in fruits and vegetables has the opposite effect and strengthens skeletal health. ... >

Some 'Good Cholesterol' Is Actually Bad, Study Shows (December 3, 2008) -- If you think your levels of "good cholesterol" are good enough, a new study suggests that you may want to think again. Researchers show that good cholesterol (HDL) has varying degrees of quality and that poor quality HDL is actually bad for you. ... >

Antioxidants Are Unlikely To Prevent Aging, Study Suggests (December 2, 2008) -- Diets and beauty products which claim to have anti-oxidant properties are unlikely to prevent aging, according to new research. Scientists in England say this is because a key 50-year-old theory about the causes of aging is wrong. ...

"Oxidative damage is clearly not a universal, major driver of the aging process. Other factors, such as chemical reactions involving sugars in our body, clearly play a role."

Eating Eggs When Pregnant Affects Breast Cancer In Offspring (December 2, 2008) -- A stunning discovery based on epigenetics (the inheritance of propensities acquired in the womb) reveals that consuming choline -- a nutrient found in eggs and other foods -- during pregnancy may significantly affect breast cancer outcomes for a mother's offspring. This finding is the first to link choline consumption during pregnancy to breast cancer. It also is the first to identify possible choline-related genetic changes that affect breast cancer survival rates. The 'genetic impact' of a pregnant woman's diet has a profound effect on her child. ... >

It Takes Guts To Build Bone, Scientists Discover (December 1, 2008) -- Bone growth is controlled in the gut through serotonin, the same naturally present chemical used by the brain to influence mood, appetite and sleep, according to a new discovery. Until now, the skeleton was thought to control bone growth and serotonin was known as a neurotransmitter acting in the brain. This insight could transform how osteoporosis is treated by giving doctors a way to increase bone mass, not just slow its loss. ... >

Acupuncture Just As Effective Without Needle Puncture, Study Shows (December 1, 2008) -- Acupuncture works - but it works equally well with or without needle penetration. This conclusion can be drawn from a treatment study involving cancer patients suffering from nausea during radiotherapy. ... >

Melatonin May Save Eyesight In Inflammatory Disease, Study Suggests (December 1, 2008) -- Current research suggests that melatonin therapy may help treat uveitis, a common inflammatory eye disease. ... >

Potentially Universal Mechanism Of Aging Identified (November 27, 2008) -- Researchers have uncovered what may be a universal cause of aging, one that applies to both single cell organisms such as yeast and multicellular organisms, including mammals. This is the first time that such an evolutionarily conserved aging mechanism has been identified between such diverse organisms. The mechanism probably dates back more than one billion years. The study shows how DNA damage eventually leads to a breakdown in the cell's ability to properly regulate which genes are switched on and off in particular settings. ... >

"According to this specific mechanism, while DNA damage exacerbates aging, the actual cause is not the DNA damage itself but the lack of gene regulation that results," says Oberdoerffer. "Lots of research has shown that this particular process of regulating gene activity, otherwise known as epigenetics, can be reversed—unlike actual mutations in DNA. We see here, through a proof-of-principal demonstration, that elements of aging can be reversed."

Adult Brain Neurons Can Remodel Connections (November 27, 2008) -- Overturning a century of prevailing thought, scientists are finding that neurons in the adult brain can remodel their connections. ... >

Exercise Increases Brain Growth Factor And Receptors, Prevents Stem Cell Drop In Middle Age (November 27, 2008) -- A new study confirms that exercise can reverse the age-related decline in the production of neural stem cells in the hippocampus of the mouse brain, and suggests that this happens because exercise restores a brain chemical which promotes the production and maturation of new stem cells. ... >

Tiny Protein Provokes Healthy Bonding Between Cells (November 26, 2008) -- In human relationships, a certain "spark" often governs whether we prefer one person to another. Critical first impressions can occur within seconds. Researchers have found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer. ... >

Gasping Helps Cardiac Arrest Victims Survive, New Research Shows (November 26, 2008) -- People who witness an individual collapse suddenly and unexpectedly should perform uninterrupted chest compressions even if the patient gasps or breathes in a funny way, a new study shows. Researchers hope their findings lead to greater willingness of untrained bystanders to jump in and perform continuous chest compressions. ... >

Household Exposure To Toxic Chemicals Lurks Unrecognized, Researchers Find (November 26, 2008) -- Many women are surprised to learn the extent of personal, in-home contamination caused by exposure to everyday consumer products, according to a team of researchers. The study, published in the Journal of Health and Social Behavior, is one of the first accounts of participants' responses to learning personal exposure data, research critical to environmental science and public health. ... >

Feed A Cold, Feed A Fever: Calorie Cut Makes It Harder To Fight Flu, Animal Study Shows (November 25, 2008) -- Dieters or those who consume fewer calories during flu season could have a harder time fighting off the flu virus, according to a nutritional immunology professor. Researchers have shown that mice with a calorie-restricted diet were more likely to die during the first few days of infection than mice with a normal diet. ... >

Calorically restricted diets in general have been shown to increase lifespan in everything from yeast to primates. "Adults can calorically restrict their diet eight months out for the year, but during the four months of flu season they need to bump it up to be ready."

New Diabetes Treatment? New Source Of Insulin-producing Cells Identified (November 25, 2008) -- Researchers have shown that insulin-producing pancreatic beta cells can form after birth or after injury from progenitor cells within the pancreas that were not beta cells. ... >

Drug Therapy For Premature Infants Destroys Brain Cells In Mice (November 25, 2008) -- A class of drugs that are used in premature infants to treat chronic lung damage can cause damage in the brain. New research suggests the drugs may cause cognitive and motor-control problems even when they are given before birth. ... >

Mineral Oil Contamination In Humans: A Health Problem? (November 24, 2008) -- From a quantitative standpoint, mineral oil is probably the largest contaminant of our body. That this contaminant can be tolerated without health concerns in humans has not been proven convincingly. An editorial in the European Journal of Lipid Science and Technology reflects on this and concludes that this proof either has to be provided or we have to take measures to reduce our exposure from all sources, including cosmetics, pharmaceuticals and the environmental contamination. ... >

Soluble Fiber, Antispasmodics And Peppermint Oil Should Be Used To Treat Irritable Bowel Syndrome, Study Suggests (November 24, 2008) -- Fiber, antispasmodics and peppermint oil are all effective therapies for irritable bowel syndrome and should become first-line treatments, according to a new study. ... >

Hope For Treating Relapse To Methamphetamine Abuse (November 24, 2008) -- A new study suggests that vigabatrin blocks drug-seeking behavior in animals previously trained to associate methamphetamine with a particular environment. ... >

Editors note: This study refers to a synthetic GABA (gamma-amino butyric acid) and we encourage the public to consider the natural form that is available at your health food store.

Plastic Additives Leach Into Medical Experiments, Research Shows (November 20, 2008) -- Using plastic lab equipment can skew or ruin the results of medical experiments, a new study finds. Researchers identified two classes of chemical compounds in commonly-used plastic lab ware that could leach into solutions. They further demonstrated that the compounds interacted biologically with, and changed the behavior of, human enzymes and brain receptors in different experiments. ... >

New Bacteria Discovered In Raw Milk (November 20, 2008) -- Raw milk is illegal in many countries as it can be contaminated with potentially harmful microbes. Contamination can also spoil the milk, making it taste bitter and turn thick and sticky. Now scientists have discovered new species of bacteria that can grow at low temperatures, spoiling raw milk even when it is refrigerated. It seems the microbial population of raw milk is much more complex than previously thought. ... >

Garlic Chemical Tablet Treats Diabetes I And II, Study Suggests (November 19, 2008) -- A drug based on a chemical found in garlic can treat diabetes types I and II when taken as a tablet, a new study shows. ... >

How Household Bleach Kills Bacteria (November 19, 2008) -- Developed more than 200 years ago and found in households around the world, chlorine bleach is among the most widely used disinfectants, yet scientists never have understood exactly how the familiar product kills bacteria. ... >

The main job of chaperones is to protect proteins from unfavorable interactions, a function that's particularly important when cells are under conditions of stress, such as the high temperatures that result from fever. These findings are not only important for understanding how bleach keeps our kitchen countertops sanitary, but they may lead to insights into how we fight off bacterial infections. Our own immune cells produce significant amounts of hypochlorite as a first line of defense to kill invading microorganisms.

Broccoli May Lower Lung Cancer Risk In Smokers (November 19, 2008) -- The cancer preventive properties of broccoli and other cruciferous vegetables appear to work specifically in smokers, according to new research. ... >

For example, among current smokers, only the consumption of raw cruciferous vegetables was associated with risk reduction of lung cancer. No significant results were found for consumption of vegetables in general and fruits.

Gut Check Reveals Vast Multicultural Community Of Bugs In Bowels (November 19, 2008) -- Mention the phrase "diverse ecosystem," and it conjures images of tropical rainforests and endangered coral reefs. It also describes the human colon. A new study reveals in greater detail than ever before the full extent of the bacterial community inhabiting the human bowel -- 10 times more diverse than previous research had suggested. ... >

Antibiotics Can Cause Pervasive, Persistent Changes To Microbiota In Human Gut (November 19, 2008) -- Using a novel technique developed at the Marine Biological Laboratory to identify different types of bacteria, scientists have completed the most precise survey to date of how microbial communities in the human gut respond to antibiotic treatment. ... >

When you change the microbial population structure in the gut, you may affect how that population is keeping indigenous pathogens at manageable levels,” says Sogin. Bacteria that do not normally cause problems may begin to grow more rapidly, and cause disease.

How Cells Take Out The Trash To Prevent Disease (November 18, 2008) -- Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard. Similarly, individual cells that make up such biological organisms as humans also have sophisticated methods for managing waste. ... >

Vitamin C Lowers Levels Of Inflammation Biomarker Considered Predictor Of Heart Disease (November 14, 2008) -- For people who have elevated levels of C-reactive protein, a predictor of heart disease, taking vitamin C supplements can help lower levels of the inflammation biomarker, according to a new study. The new findings come just days after a major, eight-year clinical trial failed to show that vitamins C or E could cut the risk of heart attacks or strokes. ... >

The researchers said that for people with elevated CRP levels, the amount of CRP reduction achieved by taking vitamin C supplements in this study is comparable to that in many other studies of cholesterol-lowering drugs called statins. They noted that several larger statin trials lowered CRP levels by about 0.2 milligrams per liter; in this latest study, vitamin C lowered CRP by 0.25 milligrams per liter.”

How Eating Red Meat Can Spur Cancer Progression: New Mechanism Identified (November 14, 2008) -- Researchers have shown a new mechanism for how human consumption of red meat and milk products could contribute to the increased risk of cancerous tumors. Their findings suggest that inflammation resulting from a molecule introduced through consumption of these foods could promote tumor growth. ... >

Neu5Gc is a type of glycan, or sugar molecule, that humans don't naturally produce, but that can be incorporated into human tissues as a result of eating red meat. The body then develops anti-Neu5Gc antibodies – an immune response that could potentially lead to chronic inflammation.” http://www.google.com/search?q=Neu5Gc

New Method Provides Panoramic View Of Protein-RNA Interactions In Living Cells (November 12, 2008) -- Scientists have developed a genome-wide platform to study how specialized proteins regulate RNA in living, intact cells. The platform allows researchers to identify, in a single experiment, every sequence within every strand of RNA to which proteins bind. The result is an unbiased and unprecedented look at how differences in RNA can explain how a worm and a human can each have 25,000 genes yet be so different. ... >

"The cell seems to be going through great trouble to regulate these RNAs in different conditions and different cell types," says Darnell. "When RNA developed the ability to make a more stable copy of itself -- DNA -- it didn't write itself off as a relic for the textbooks. It stayed at the core of complex processes in the cell."

Bacteria In Mouth Help Make Certain Foods Tasty (November 11, 2008) -- Scientists in Switzerland are reporting that bacteria in the human mouth play a role in creating the distinctive flavors of certain foods. They found that these bacteria actually produce food odors from odorless components of food, allowing people to fully savor fruits and vegetables. ... >

Can Vitamins And Minerals Prevent Hearing Loss? (November 10, 2008) -- Researchers and physicians at the University of Michigan Kresge Hearing Research Institute are hoping to reverse a rising trend of noise-induced hearing loss with a cocktail of vitamins and the mineral magnesium that has shown promise as a possible way to prevent hearing loss caused by loud noises. ... >

Embryonic Heart Exhibits Impressive Regenerative Capacity (October 14, 2008) -- A new study demonstrates that the embryonic mouse heart has an astounding capacity to regenerate, a phenomenon previously observed only in non-mammalian species. The research describes the previously unrecognized potential of the embryonic heart to replace diseased tissue through compensatory proliferation of healthy cells. ... >

Unraveling The Complexity Of Human Disease (October 14, 2008) -- The mysteries of the human genome are slowly being revealed -- but the more we uncover the more complicated the picture becomes. This was one key message to emerge from the European Science Foundation's 3rd Functional Genomics Conference. Functional genomics describes the way in which genes and their products, proteins, interact together in complex networks in living cells. If these interactions are abnormal, diseases can result. ... >

Why Starving Cells Prolong Life (October 14, 2008) -- Cellular damage due to stress is an important factor in aging processes. It is, thus, amazing that starving, which is a stress factor per se, decelerates ageing processes and extends the lifespan of organisms. It has long been known that proteins from the sirtuin family contribute to this mechanism. ... >

First Evidence That Common Pollutant May Reduce Iodine Levels In Breast Milk (October 13, 2008) -- Researchers in Texas are reporting the first evidence from human studies that perchlorate, a common pollutant increasingly found in food and water, may interfere with an infant's availability of iodine in breast milk. Iodine deficiency in infants can cause mental retardation and other health problems, the scientists note. The study also provides further evidence that iodine intake in U.S. mothers is low and that perchlorate may play a key role. ... >

New Properties Of Skin Stem Cells (October 13, 2008) -- New research reveals completely new properties of the skin’s stem cells – discoveries that contradict previous findings. The studies, which are published in Nature Genetics, show amongst other things, that hair follicle stem cells can divide actively and transport themselves through the skin tissue. ... >

The stem cells don’t behave at all in the way we’d previously thought, and are found in unexpected places.”

'Caffeine Receptor' Solved: Structure Of Important Neurological Receptor Defined (October 13, 2008) -- Scientists from the Scripps Research Institute have determined the structure of an adenosine receptor that plays a critical role in a number of important physiological processes including pain, breathing, and heart function. The findings could lead to the development of a new class of therapeutics for treating numerous neurological disorders, including Parkinson's and Huntington disease. ... >

'Junk' DNA Proves Functional; Helps Explain Human Differences From Other Species (November 5, 2008) -- In a new study, scientists in Singapore report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species. ... >

More than 50 percent of human DNA has been referred to as "junk" because it consists of copies of nearly identical sequences. This research also shows that these repeats are anything but "junk DNA,".

Folic Acid, B Vitamins Do Not Appear To Affect Cancer Risk (November 5, 2008) -- A daily supplementation combination that included folic acid and vitamin B6 and B12 had no significant effect on the overall risk of cancer, including breast cancer, among women at high risk of cardiovascular disease, according to new study. ... >

Previously Unknown Immune Cell May Help Those With Crohn's And Colitis (November 5, 2008) -- The tonsils and lymphoid tissues in the intestinal tract that help protect the body from external pathogens are the home base of a rare newly identified immune cell. Researchers indicate that the immune cells could have a therapeutic role in inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. ... >

"That finding suggests that these cells play a role in maintaining a balance in the immune system between inflammatory processes and anti-inflammatory processes."

Fibromyalgia Can No Longer Be Called The 'Invisible' Syndrome (November 4, 2008) -- Using single photon emission computed tomography, researchers in France were able to detect functional abnormalities in certain regions in the brains of patients diagnosed with fibromyalgia, reinforcing the idea that symptoms of the disorder are related to a dysfunction in those parts of the brain where pain is processed. ... >

Optimal Dose Of Vitamin E Maximizes Benefits, Minimizes Risk (November 4, 2008) -- Excess vitamin E can promote bleeding by interfering with vitamin K. Nutrition researchers review some possible explanations. ... >

Antioxidant Effects From Eating Almonds (November 4, 2008) -- Eating almonds significantly decreased levels of two biomarkers for oxidative stress in a group of 27 male and female volunteers with elevated cholesterol. ... >

Biologists Spy On The Secret Inner Life Of A Cell (November 4, 2008) -- The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Antibodies help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases. Images from Caltech biologists reveal for the first time the complicated process by which antibodies are shuttled from mother's milk, through her baby's gut and into the bloodstream -- offering new insight into the mammalian immune system. ... >

The images offered more surprises. Complexes were collected within cells inside large vesicles, called "multivesicular bodies," that contain other small vesicles. The vesicles previously were believed to be responsible only for the disposal of cellular refuse and were not thought to be involved in the transport of vital proteins.

Human Genes: Alternative Splicing Far More Common Than Thought (November 4, 2008) -- Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. Now, scientists have shown that this phenomenon, known as alternative splicing, is both far more prevalent and varies more between tissues than was previously believed. ... >

"A decade ago, alternative splicing of a gene was considered unusual, exotic … but it turns out that's not true at all — it's a nearly universal feature of human genes."

Prenatal Exposure To Famine May Lead To Persistent Epigenetic Changes (November 3, 2008) -- Prenatal exposure to famine can lead to epigenetic changes that may affect a person's health into midlife. New findings show a trickle-down effect from pregnant women to the DNA of their unborn children and the timeframe over which such early damage can operate. These data are the first to show that early-life environmental conditions can cause epigenetic changes in humans that persist throughout life. ... >

"Understanding how epigenetic control responds to well defined early exposures may shed light on the link between development and health over a life time and ultimately suggest new ways to prevent human disease," said Dr. Lumey.

How Signals Flow Between Neurons: New Research Explains Membrane Fusion At Synapse (November 3, 2008) -- Imagine a bathtub with two soap bubbles colliding but never fusing. Then you add detergent, and the surface of the water goes flat as the walls of the bubbles collapse and merge. Scientists have used that analogy to describe the action of synaptotagmin-1, which acts to catalyze the fusion of the membranes of tiny neurotransmitter-filled bubbles called vesicles with the wall membrane of a neuron. This action allows signals to flow between neurons. ... >

It takes no more than 1/1,000th of a second for this to occur. Neuroscientists are not only fascinated by this astonishing speed, but they also recognize that disturbing the speed of synaptic transmission has deleterious consequences on brain function and can lead to various diseases of the nervous system including schizophrenia, depression, Parkinson's disease, epilepsy and Alzheimer's disease.”

Friend Or Foe? How The Body's Clot-busting System Speeds Up Atherosclerosis (November 2, 2008) -- Scientists have been puzzled by the fact that high levels of plasmin in blood and high levels of urokinase in artery walls are linked to high risk for rapid progression of atherosclerosis and heart attacks. Are these naturally occurring clot busters contributors to disease or evidence of the body's attempt to fight it? Molecular biology research shows interactions between urokinase and plasminogen accelerate atherosclerosis. Genetic loss of plasminogen production (the precursor to plasmin) protects mice against atherosclerosis, even when urokinase levels are elevated. ... >

"However, despite much work," he said, citing other studies that seemed to predict a different outcome, "a coherent picture of the role of the urokinase/plasminogen system in the development of atherosclerosis has not yet emerged."
