Did you know you can improve your search engine rankings by providing optimized articles and placing them on your site?
So, you want to rank on the first page of Google. Well, who doesn't? You've pumped your web site full of keywords - even hired some know-it-all search engine optimization specialists to work a little magic. Still, you're just not getting the results you're looking for. So, what's the answer?
Professional, high-quality professional writing. Article writer, web content writer, resume writer, copy editor, business writer, travel writer, biography writer, financial writer, etc.
Sequencing a patient's entire genome to discover the source of his or her disease is not routine, but geneticists are getting close. A case report shows how researchers can combine a simple blood test with an "executive summary" scan of the genome to diagnose a severe glycosylation disorder.
One of the big mysteries in biology is why cells age. Now scientists report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.
Newly divorced middle aged women are more vulnerable to contract HIV and other sexually transmitted diseases, according to new research, because they tend to let their guard down with new sexual partners and avoid using protection since they are not afraid of getting pregnant.
Could the use of vitamin and mineral supplements in a regular diet help to reduce the risk of colon cancer and protect against carcinogens? A study published in the Canadian Journal of Physiology and Pharmacology found that rats given regular multivitamin and mineral supplements showed a significantly lower risk of developing colon cancer when they were exposed to carcinogens.
Refugee children have scant access to medical care and are particularly vulnerable to disease. Fresh research results show that just a few hours of schooling a week may have a pronounced positive impact on their health not only in childhood but later in life when they achieve adulthood.
Placebos reduce pain by creating an expectation of relief. Distraction -- say, doing a puzzle -- relieves it by keeping the brain busy. But do they use the same brain processes? Neuromaging suggests they do. When applying a placebo, scientists see activity in the dorsolateral prefrontal cortex. That's the part of the brain that controls high-level cognitive functions like working memory and attention -- which is what you use to do that distracting puzzle.
In the largest and longest head-to-head comparison of two anti-clotting medications, warfarin and aspirin were similar in preventing deaths and strokes in heart failure patients with normal heart rhythm, according to new research.

Though pacemakers require only small amounts of energy (about 1 millionth of a Watt), their batteries have to be replaced periodically, which means multiple surgeries for patients. Researchers have searched for ways to prolong battery life - trying to generate energy to power a pacemaker using blood sugar, or the motion of the hands and legs - but these methods either interfere with metabolism or require a more drastic surgery, such as passing a wire from the limbs to the chest area...
A new study recently published in the Journal of Integrated Pest Management (JIPM) shows that from 2003 to 2008, the use of insecticide active ingredients was reduced by about 90% in University of Florida housing buildings after an Integrated Pest Management (IPM) program was implemented. IPM is a systematic approach to managing pests based on long-term prevention or suppression by a variety of methods that are cost effective and minimize risks to human health and the environment...
The same gene mutations linked to inherited, early-onset Alzheimer's disease have been found in people with the more common late-onset form of the illness. The discovery by researchers at Washington University School of Medicine in St. Louis may lead doctors and researchers to change the way Alzheimer's disease is classified. They reported their findings in the online journal PLoS One (Public Library of Science)...
Rutgers scientists have uncovered genetic clues as to why some mice no longer in danger are still fearful while others are resilient to traumatic experiences - knowledge that could help those suffering with crippling anxiety and PTSD. "Our work with mice demonstrates how genes play a role in developing and extinguishing pathological fear like Post Traumatic Stress Disorder," says Gleb Shumyatsky, an associate professor in the Department of Genetics in the School of Arts and Sciences...
A research team led by investigators at Mayo Clinic in Florida has found that a small device worn on a patient's brow can be useful in monitoring stroke patients in the hospital. The device measures blood oxygen, similar to a pulse oximeter, which is clipped onto a finger. Their study, published in Neurosurgical Focus, suggests this tool, known as frontal near-infrared spectroscopy (NIRS), could offer hospital physicians a safe and cost-effective way to monitor patients who are being treated for a stroke, in real time...
Nighttime visits to the bathroom are generally associated with being pregnant or having an enlarged prostate, but the problem can affect youngsters, too. A new study sheds light on why some children may need to urinate more often during the rest cycle. Danish researchers have found that sleep deprivation causes healthy children, between the ages of eight and twelve, to urinate significantly more frequently, excrete more sodium in their urine, have altered regulation of the hormones important for excretion, and have higher blood pressure and heart rates...
Occasional erratic heart rhythms appear to cause about one-fifth of strokes for which a cause is not readily established, according to research presented at the American Stroke Association's International Stroke Conference 2012. About one-third of survivors leave the hospital with the cause of their stroke still undetermined. "Identifying and treating these patients for irregular rhythm could reduce the recurrence of stroke by 40 percent compared to reducing the risk by treating them with aspirin," said Daniel J. Miller, M.D...
