ESHRE sets standards for cross-border reproductive care

The Guide aims to ensure high-quality assisted reproduction treatment as defined by the European Union criteria for good quality medical treatment and the ESHRE position paper on Good clinical treatment in Assisted Reproduction. Although in principle foreign and local patients should be treated the same and with the best possible treatment, there is evidence that this is not always the case. The Guide is based on the core principles in health care: 'equity', 'safety', 'efficiency', 'patient centeredness', 'timeliness' and 'effectiveness'. The principle of equity means ...

What's your gut type?

In the future, when you walk into a doctor's surgery or hospital, you could be asked not just about your allergies and blood group, but also about your gut type. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and collaborators in the international MetaHIT consortium, have found that humans have 3 different gut types. The study, published today in Nature, also uncovers microbial genetic markers that are related to traits like age, gender and body-mass index. These bacterial genes could one day be used to help diagnose and predict outcomes ...

Contemporary climate change alters the pace and drivers of extinction

Local extinction rates of American pikas have increased nearly five-fold in the last 10 years, and the rate at which the climate-sensitive species is moving up mountain slopes has increased 11-fold, since the 20th century, according to a study soon to be published in Global Change Biology. The research strongly suggests that the American pika's distribution throughout the Great Basin is changing at an increasingly rapid rate. The pika (Ochotona princeps), a small, hamster-looking animal sensitive to climate, occurs commonly in rocky talus slopes and lava flows throughout ...

Beams of electrons link Saturn with its moon Enceladus

Data from NASA's Cassini spacecraft have revealed that Enceladus, one of Saturn's diminutive moons, is linked to Saturn by powerful electrical currents - beams of electrons that flow back and forth between the planet and moon. The finding is part of a paper published in Nature today. CAPS, one of the instruments on board Cassini which made the electron beam discovery, includes a electron sensor called CAPS-ELS – led by UCL (University College London). Since Cassini's arrival at Saturn in 2004 it has passed 500km-wide Enceladus 14 times, gradually discovering more of ...

Avoiding Home Loan Modification Scams

The nationwide economic recession has cost tens of thousands their jobs, forced millions into foreclosure and resulted in countless bankruptcy filings. Despite their best efforts, many people are falling behind on mortgage payments due to financial circumstances beyond their control. In an effort to avoid foreclosure, more and more people are seeking loan modifications as a way to lower payments temporarily (or permanently), making them more affordable and making keeping the home a real possibility. Unfortunately, at a time when foreclosures are at a record high, unscrupulous ...

Molecule Nutlin-3a activates a signal inducing cell death and senescence in primary brain tumors

Researchers of Apoptosis and Cancer Group of the Bellvitge Biomedical Research Institute (IDIBELL) have found that a small molecule, Nutlin-3a, an antagonist of MDM2 protein, stimulates the signalling pathway of another protein, p53. By this way, it induces cell death and senescence (loss of proliferative capacity) in brain cancer, a fact that slows its growth. These results open the door for MDM2 agonists as new treatments for glioblastomas. The study has been published at the journal PLoS ONE. Glioblastoma multiforme is the most common brain tumour in adults and the ...

How molecules get to the right place at the right time

In a multicellular organism, different cells fulfill a range of diversified functions. Often such specialization depends on the delivery of molecular goods to distinct places within a cell. It ensures that particular functions only occur at defined cellular sites. This establishment of intracellular asymmetry in the otherwise fluid environment of the cell cytoplasm requires active transport processes. Messenger RNAs (mRNA) represent an especially important type of freight. They are copies of genetic information stored in the nucleus. In the cytoplasm the information encoded ...

Lightning-fast materials testing using ultrasound

Expectant mothers are familiar with the procedure: the physician examines them with an ultrasound apparatus that displays lifelike images of the fetus on the monitor. The application of this technology has been customary in medicine for years; in materials testing though, it has been used only in relatively rudimentary form to date. Researchers at the Fraunhofer Institute for Non-Destructive Testing IZFP in Saarbrücken have adapted the conventional sonar procedure – a simple ultrasound method – and have succeeded in generating three-dimensional images with the aid of innovative ...

Nassau County Crime Lab Shut Down

Prosecutors trust that the information they receive from crime labs is correct and accurate. The results from tests run at the lab are used to help build cases against those accused of crimes. When this information is inaccurate it can lead to questions for both past and future cases, and in some instances, lead to innocent people being convicted of crimes they did not commit. The Nassau County crime lab recently became the only police lab in the nation to completely close its doors due to its inability to follow procedures. The lab's troubles started in December 2010. ...

How can we measure infants' pain after an operation?

It turns out to be difficult to find out exactly how much a child who cannot yet speak suffers after a surgical operation. Researchers at the University Hospital of La Paz, in Madrid, have validated the 'Llanto' scale, the first, and only, tool in Spanish which measures infant pain rapidly and simply. "The lack of appropriate tools prevents health professionals from knowing if a pre-verbal child who cannot tell us how much a surgical wound hurts, is being treated correctly", explains Francisco Reinoso, lead author of the study and head of the section of Paediatric Anaesthesia ...

Shades of gray: LSU researcher studies South Louisiana's historical ties to the oil industry

BATON ROUGE – On the one year anniversary of the Deepwater Horizon oil spill that took the lives of 11 men and devastated the livelihoods of many residents of coastal Louisiana, it's difficult to put the complicated relationship between people and oil into perspective. While the environmental impacts have thus far not been as pervasive as originally feared, most scientists are in agreement that it is still simply too early to tell. However, dependence upon oil has not lessened over the past year, laying the groundwork for some very significant debates between environmentalists ...

Rotten meat doesn't stand a chance

Is the vacuum-packed chicken leg really still fresh and edible? Looks alone do not tell the whole story. And the "best-before" date is no guarantee, either. Scandals involving the sale of rotten meat have added to the uncertainty, and the customer him- or herself may be shortening the shelf life through improper storage. This is an area in which a sensor film developed by the Fraunhofer Research Institution for Modular Solid State Technologies EMFT in Munich can immediately give a green – or rather: yellow light, or warn of spoiled goods. EMFT developed the film in a project ...

California Family Courts: Take a Number ... A Very Large Number

California Family Courts deal with a huge volume of traffic every year. Just the Los Angeles Superior Court -- Family Law handles 100,000 filings per year. The high number of filings combined with the fact that over 70 percent of litigants in family law are unrepresented -- meaning they don't have an attorney -- many courts have adopted local rules and procedures in an attempt to more efficiently process the high volume of family law cases. While some of these rules and procedures help speed up the process, the price that efficiency comes at was the virtual elimination ...

A galactic rose highlights Hubble's 21st anniversary

This image, taken by the NASA/ESA Hubble Space Telescope, shows a group of interacting galaxies called Arp 273. The larger of the spiral galaxies, known as UGC 1810, has a disc that is tidally distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. The swathe of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light. The smaller, nearly edge-on companion shows distinct signs of intense star formation at its ...

New Loan Modification Proposal Would Help Distressed Homeowners

While the foreclosure crisis has had a devastating effect on the real estate market, loan modifications have been equally as troubling for struggling homeowners. The Home Affordable Modification Program (HAMP) was supposed to help millions of Americans struggling to pay their mortgages by modifying home loans to reflect the current value of their properties. Unfortunately, HAMP has not been as effective as first contemplated. As of March 2011, less than 500,000 mortgages have been modified through this program, when it was estimated that 3-4 million mortgages would be ...

How TRIM5 fights HIV

Thanks to a certain protein, rhesus monkeys are resistant to HIV. Known as TRIM5, the protein prevents the HI virus from multiplying once it has entered the cell. Researchers from the universities of Geneva and Zurich have now discovered the protein's mechanism, as they report in Nature. This also opens up new prospects for fighting HIV in humans. Unlike people, certain monkey species, such as rhesus or night monkeys, are resistant to HIV thanks to TRIM5, a cellular protein: In the case of an HIV infection, the protein intercepts the virus as soon as it enters the ...

MicroRNA mediates gene-diet interaction related to obesity

BOSTON (April 20, 2011, 5pm ET) − Eating more n-3 polyunsaturated fatty acids, commonly known as omega-3 fatty acids, may help carriers of a genetic variant on the perilipin 4 (PLIN4) gene locus lose weight more efficiently. Based on this observation, researchers at the Jean Mayer Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University identified a microRNA (miRNA) which may elucidate the underlying biological mechanism. Led by Jose M. Ordovas, PhD, director of the Nutrition and Genomics Laboratory at the USDA HNRCA, researchers genotyped seven ...

Breastfeeding tied to stronger maternal response to baby's cry

A new study from the Journal of Child Psychology and Psychiatry finds that mothers who feed their babies breast milk exclusively, as opposed to formula, are more likely to bond emotionally with their child during the first few months after delivery. The breastfeeding mothers surveyed for the study showed greater responses to their infant's cry in brain regions related to caregiving behavior and empathy than mothers who relied upon formula as the baby's main food source. This is the first paper to examine the underlying neurobiological mechanisms as a function of breastfeeding, ...

Consider Bankruptcy to Discharge Credit Card Debt

When Congress' recent revisions to federal laws governing credit card usage went into effect, some consumers saw interest rates double or even triple. The law now allows for credit providers to be more flexible with interest rate raises, provided they give the cardholders notice of the action and share information about the total amount of the debt and approximately how long it will take to pay it off. The changes in the law were initially introduced as a way to protect consumers, but, in practice they are much more biased toward lenders. Following the enacting of those ...
