Searching for therapeutic synergy in primary effusion lymphoma

2013-05-01
(Press-News.org) Primary effusion lymphoma (PEL) is a rare, fatal form of aggressive B-cell lymphoma caused by Kaposi's sarcoma-associated herpesvirus (KSHV). The disease most commonly occurs in immunocompromised patients, such as those with HIV and the elderly. Because current treatment options are not effective, there is a great need for new PEL therapies. In this issue of the Journal of Clinical Investigation, Juan Carlos Ramos and colleagues at the University of Miami used an immunocompromised mouse model of PEL to determine the efficacy of Bortezomib/Vorinostat combination therapy, two drugs that are currently being used to treat multiple myeloma and cutaneous T cell lymphoma, respectively. They found that this treatment combination reactivated virus-induced cell lysis and induced PEL cell death, increasing the lifespan of mice with PEL tumors. These findings indicate that this drug combination could potentially be beneficial in immunocompromised patients with KSHV-associated malignancies.

2 new papers on dabigatran etexilate (Pradaxa) and intracranial hemorrhage

2013-05-01
Charlottesville, VA (May 1, 2013). The Journal of Neurosurgery Publishing Group is pleased to announce publication of two new studies on dabigatran etexilate (Pradaxa®) and intracranial hemorrhage: one in the Journal of Neurosurgery and the other in Neurosurgical Focus. Background Dabigatran is an oral anticoagulant (blood thinner) approved by the US FDA in 2010 to lower the risk of stroke and prevent systemic embolism in persons with nonvalvular atrial fibrillation. Unlike warfarin, the most popular drug prescribed for this condition, dabigatran carries a lower risk ...

'Dirty dozen' invasive species threaten UK

2013-05-01
The researchers, Dr Bellinda Gallardo and Dr David Aldridge from the University of Cambridge, focussed on the 'dirty dozen' – a group of high-risk invasive aquatic plants and animals. Some, like the killer shrimp (Dikerogammarus villosus) and the bloody red mysid (Hemimysis anomala) are already in UK but have yet to spread. Others, such as the Asian clam (Corbicula fluminalis) and the marmokrebs, a crayfish (Procambarus fallax) may not yet have arrived. Working with Species Distribution Models, which are routinely used to predict which regions most suit invasive species, ...

The day NASA's Fermi dodged a 1.5-ton bullet

2013-05-01
NASA scientists don't often learn that their spacecraft is at risk of crashing into another satellite. But when Julie McEnery, the project scientist for NASA's Fermi Gamma-ray Space Telescope, checked her email on March 29, 2012, she found herself facing this precise situation. While Fermi is in fine shape today, continuing its mission to map the highest-energy light in the universe, the story of how it sidestepped a potential disaster offers a glimpse at an underappreciated aspect of managing a space mission: orbital traffic control. As McEnery worked through her ...

Outdoor recess time can reduce the risk of nearsightedness in children

2013-05-01
SAN FRANCISCO – May 1, 2013 – Two new studies add to the growing evidence that spending time outdoors may help prevent or minimize nearsightedness in children. A study conducted in Taiwan, which is the first to use an educational policy as a public vision health intervention, finds that when children are required to spend recess time outdoors, their risk of nearsightedness is reduced. A separate study in Danish children is the first to show a direct correlation between seasonal fluctuations in daylight, eye growth and the rate of nearsightedness progression. The research ...

Gastric bypass findings could lead to diabetes treatment

2013-05-01
A Lund University research team has shed new light on why gastric bypass often sends diabetes into remission rapidly, opening the door to developing treatment with the same effect. 85% of patients with type 2 diabetes who undergo a gastric bypass procedure recover from the disease within a few days, showing a return to normal blood sugar levels - long before any weight loss. Until now, there have been few clues as to why this happens. "Most previous studies have analysed samples taken from patients before and after a gastric bypass, but there is a risk that the results ...

CPR 'hands-only' guidelines may not be best for rural areas

2013-05-01
TORONTO, May 1,2013—Hands-only CPR (CPR without mouth-to-mouth resuscitation), may not be the best method for rural or remote areas or for anyone who has to wait more than a few minutes for an ambulance, a new study suggests. New guidelines released by the American Heart Association in 2010 permit the use of simpler hand-only or compression-only CPR in some cases instead of conventional CPR. If ambulances come quickly, experts believe that instructing people to just "push hard, push fast" saves more lives. But a literature review by Dr. Aaron Orkin found little evidence ...

'Traffic' in our cells works both for and against us

2013-05-01
Jerusalem, May 1, 2013 – A mechanism that permits essential substances to enter our cells while at the same time removing from them harmful components also has a "down side." This negative aspect prevents vital drugs, such as anti-cancer drugs, from achieving their designed functions, while also enabling bacterial cells to develop resistance to penetration of antibiotics. A study aimed at a fuller understanding of how this selective mechanism works -- with a view towards better controlling it through new drug designs -- is the subject of an article by Hebrew University ...

The biology behind binge eating

2013-05-01
EAST LANSING, Mich. — Female rats are much more likely to binge eat than male rats, according to new research that provides some of the strongest evidence yet that biology plays a role in eating disorders. The study, by Michigan State University scientists, is the first to establish sex differences in rates of binge eating in animals and has implications for humans. Binge eating is one of the core symptoms of most eating disorders, including bulimia nervosa and the binge/purge subtype of anorexia nervosa, and females are four to 10 times more likely than males to have ...

UEA research reveals consequences of a lifetime of sexual competition

2013-05-01
Research published today in the journal Evolution reveals how fruit flies (Drosophila melanogaster) that are subjected to continual competition from mating rivals, mate for longer and produce more offspring in early life. But they pay a high price – a shorter lifespan and reduced mating ability later in life. It is the first study to quantify the consequences of lifetime exposure to rivals. Researchers say that 'trade-offs' between reproduction and lifespan are common across the whole animal kingdom, so in principle the findings could be applicable more generally. The ...

Early intervention found cost effective through school years

2013-05-01
(NEW YORK, N.Y.) May 1, 2013 – The Early Start Denver Model (ESDM), a comprehensive behavioral early intervention program that is appropriate for children with autism spectrum disorder (ASD) as young as 12 months, has been found to reduce the need for ASD therapies and special education services through the school years following their early intervention. These findings were presented by David S. Mandell, Sc.D., Associate Professor, Director, Center for Mental Health Policy & Services Research, University of Pennsylvania Perelman School of Medicine, today at the Autism ...
