Emerging cryopreservation techniques are increasing hope of restoring fertility for women after diseases such as ovarian cancer that lead to destruction of reproductive tissue. The same techniques can also be used to maintain stocks of farm animals, and protect against extinction of endangered animal species by maintaining banks of ovarian tissue or even nascent embryos that can used to produce offspring at some point in the future.

Troubled children hurt their classmates' math and reading scores and worsen their behavior, according to new research by economists at the University of California, Davis, and University of Pittsburgh.
The study, "Externalities in the Classroom: How Children Exposed to Domestic Violence Affect Everyone's Kids," was published in August by the National Bureau of Economic Research and is available online at http://papers.nber.org/papers/w14246.
Researchers from the University of Newcastle are investigating a new way to help schizophrenia patients develop their communication and social skills.
PhD student Kathryn McCabe is studying the eye movements of people with schizophrenia to understand better how they view other people's faces.
Ms McCabe said the ability to recognise facial expressions and social clues was impaired in people with schizophrenia.
Berkeley -- Researchers at the University of California, Berkeley, are continuing their march toward creating a synthetic, gecko-like adhesive, one sticky step at a time. Their latest milestone is the first adhesive that cleans itself after each use without the need for water or chemicals, much like the remarkable hairs found on the gecko lizard's toes.
People who survived the Indian Ocean tsunami or lost loved ones in the disaster went through a complex process of trauma and grief, according to research published in the latest Journal of Advanced Nursing.
In-depth interviews carried out over the course of a year by nurse researchers found that a number of common themes emerged when they talked to people about their emotions and attitudes to life following the tragedy.
They hope that these will provide useful guidance to help nurses and other healthcare professionals to deal with traumatic events in the future.
Retail medical clinics located in pharmacies and other stores typically attract insured and uninsured patients who are seeking help for a small group of easy-to-treat illnesses or preventive care and do not otherwise have a regular health care provider, according to a new RAND Corporation study.
Some studies have demonstrated H. pylori stimulates the release of interleukin-8 (IL-8) from gastric epithelia, which initiates inflammatory damage to gastric mucosa and plays a crucial role in the pathogenesis of H. pylori infections. H. pylori lipopolysaccharide (H. pylori-LPS) is the major initiator in H. pylori-induced IL-8 production via activation of Toll-like receptor 4 (TLR4) pathway in gastric epithelia. Considering the novel finding that H.
Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA. There are two branches in the checkpoint response pathway—ataxia telangiectasia-mutated (ATM) and ATM-Rad3-related (ATR). Many viruses are now known to interact with DNA damage sensing and repair machinery. These viruses have evolved tactics to eliminate, circumvent, or exploit various aspects of the DNA damage response of the host cell.
It is widely accepted that urgent endoscopy for UGIB should be performed within 24 hour from the admission. However, within this period of time, it is still unclear whether it should be performed either very early – i.e. within 2 hour – or in a more delayed interval, such as after 6, 12 or 24 hour. Therefore, optimal timing for urgent endoscopy in UGIB patients has not been yet established.
Serology and C14-UBT are the most commonly used non-invasive tests of H. pylori infection. The diagnostic characteristics of the tests depend also on the prevalence of H. pylori infection in the population tested. The diagnostic characteristics of the tests depend also on the prevalence of H. pylori infection in the population tested. Higher prevalences would imply higher sensitivity and lower specificity. There are reports suggesting that there is an association between the level of H.
SIBO is a common feature in IBS and in fact may be directly related to the genesis of IBS symptoms. An ERBHAL on a lactulose breath test may indicate SIBO. Antibiotics and elemental diets have been shown to be effective in treating SIBO, but the efficacy of probiotics is untested. A pilot study was undertaken to determine the effect of L. strain Shirota (Yakult(R)) on intestinal fermentation patterns of IBS patients.
Washington, DC (August 18, 2008) — In the world of Down syndrome, 'Mr. C' is a rarity. A real person whose progress has been tracked for the past 16 years, at seventy, 'Mr. C' has well surpassed the average life expectancy of a person with Down syndrome, currently in the late fifties, but in the teens when 'Mr. C' was born. Further, 'Mr. C' does not exhibit clinical symptoms of Alzheimer's disease, which is almost a given for people with typical Down syndrome over 65 yeas of age. 'Mr.
Sticky glue secreted by the bacterium Staphylococcus aureus could be the clue scientists have been searching for to make an effective vaccine against MRSA, medical researchers heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
New nanotechnology paints for walls, ceilings, and surfaces could be used to kill hospital superbugs when fluorescent lights are switched on, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
The new paints contain tiny particles of titanium dioxide, which is the dazzling white compound often used as a brightener in commercial paints. It will also be familiar to tennis fans as the powder used for the white lines to mark out the courts at Wimbledon.
Killer dyes that can wipe out bacteria could help solve the superbug problems faced by surgical patients, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
"We showed that 99% of the potentially dangerous Staphylococcus aureus bacteria in infected wounds can be killed using a green dye that gives off toxic molecules when it is activated by near-infrared light," said Dr Ghada Omar from University College London, UK.
