How To Confirm The Causes Of Iron Deficiency Anemia In Young Women Posted: 06 Jul 2009 08:00 PM PDT A research group from Italy showed that a pre-endoscopic serological screening for Helicobacter pylori and celiac disease may help to confirm the causes of iron deficiency anemia in young women. This screening permits the identification of patients at higher risk of iron malbsorption related disease such as Helicobacter pylori-related gastritis and celiac disease and to select patients to submit for gastroscopy.

Single Protein Dimers Observed Wavering Between Two Symmetrically Opposed Structures Posted: 06 Jul 2009 08:00 PM PDT Researchers have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the protein's chemical environment. One folded form is active and the other is inactive, but the protein can easily morph from one state to another.

Babies Born After Freeze-thawing Embryos Do Just As Well Regardless Of Whether They Were Created Via ICSI Or Standard IVF Posted: 06 Jul 2009 08:00 PM PDT Analysis of the longest running ICSI program in the United States has found reassuring evidence that babies born from frozen embryos fertilized via ICSI (intracytoplasmic sperm injection) do just as well as those born from frozen embryos fertilized via standard IVF treatment.

Battle Of The Sexes Benefits Offspring, Says Research In Birds Posted: 06 Jul 2009 05:00 PM PDT Parents compensate for a lazy partner by working harder to bring up their offspring, but not enough to completely make up for the lack of parenting, says research by bird biologists.

Variations In Five Genes Raise Risk For Most Common Brain Tumors Posted: 06 Jul 2009 05:00 PM PDT Common genetic variations spread across five genes raise a person's risk of developing the most frequent type of brain tumor, scientists report.

Ancient Drought And Rapid Cooling Drastically Altered Climate Posted: 06 Jul 2009 05:00 PM PDT Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate. The events -- one, a massive, long-lived drought believed to have dried large portions of Africa and Asia, and the other, a rapid cooling that accelerated the growth of tropical glaciers -- left signals in ice cores and other geologic records from around the world.

Vitamin A Derivative Provides Clues To Better Breast Cancer Drugs Posted: 06 Jul 2009 05:00 PM PDT A comparison of the effects of estrogen and retinoic acid, a derivative of vitamin A, on the genome of breast cancer cells showed that they have a "yin-yang" effect, with estrogen tipping the scales towards cell proliferation and retinoic acid inhibiting cellular growth. The finding could lead researchers to a new set of drug targets for this disease.

Natural Deep Earth Pump Fuels Earthquakes And Ore Posted: 06 Jul 2009 05:00 PM PDT For the first time scientists have discovered the presence of a natural deep earth pump that is a crucial element in the formation of ore deposits and earthquakes.

Sick Children Do Not Always Have Their Pain-relief Needs Met Posted: 06 Jul 2009 05:00 PM PDT Despite great effort to reduce anxiety, fear and pain, related to health care, children still considered "being in pain" as the worst aspect of a medical procedure, according to new research.

Fireworks Display In The Helix Nebula Posted: 06 Jul 2009 02:00 PM PDT The Helix Nebula, NGC 7293, is not only one of the most interesting and beautiful planetary nebulae; it is also one of the closest nebulae to Earth, at a distance of only 710 light years away. A new image, taken with an infrared camera on the Subaru Telescope in Hawaii, shows tens of thousands of previously unseen comet-shaped knots inside the nebula. The sheer number of knots -- more than have ever been seen before -- looks like a massive fireworks display in space.

Nitrates May Be Environmental Trigger For Alzheimer’s, Diabetes And Parkinson's Disease Posted: 06 Jul 2009 02:00 PM PDT A new study has found a substantial link between increased levels of nitrates in our environment and food with increased deaths from diseases, including Alzheimer's, diabetes mellitus and Parkinson's.

To Protect Threatened Bat Species, Street Lights Out Posted: 06 Jul 2009 02:00 PM PDT Slow-flying, woodland bats -- which tend to be at greater risk from extinction than their speedier kin -- really don't like street lights, according to a new study. Lesser horseshoe bats will stray from their usual flight routes to steer clear of the artificial glow from lights that are similar to everyday street lights, the new report shows.

Urine Test For Appendicitis To Indicate Which Children Need Surgery? Posted: 06 Jul 2009 02:00 PM PDT Appendicitis is the most common childhood surgical emergency, but can be hard to diagnose, often leading to either unnecessary surgery or serious complications when the condition is missed. Now, emergency physicians and proteomics researchers have identified a urine protein that might serve as a "biomarker" for appendicitis, the most accurate one known to date.

Genome-wide Map Shows Precisely Where MicroRNAs Do Their Work Posted: 06 Jul 2009 02:00 PM PDT MicroRNAs are the newest kid on the genetic block. By regulating the unzipping of genetic information, these tiny molecules have set the scientific world alight with such wide-ranging applications as onions that can't make you cry and therapeutic potential for new treatments for viral infections, cancer and degenerative diseases. But the question remains: How do they work?

Being Overweight Or Obese In Mid-life Linked To Increased Risk Of Reduced Memory And Thinking Skills In Late Life Posted: 06 Jul 2009 02:00 PM PDT Individuals with higher mid-life Body Mass Index (BMI) in the 1960s have been found to have lower memory and thinking skills and a sharper decline in these abilities in old age, compared to those with lower BMI in mid-life.
