People who have had kidney stones are twice as likely to need dialysis or a kidney transplant later in life, demonstrates recently published findings by medical researchers at the University of Alberta. Their article was recently published in the British Medical Journal. Faculty of Medicine & Dentistry researchers Todd Alexander and Marcello Tonelli tracked data of more than three million Albertans over an 11-year period from 1997 to 2009. They discovered those with a history of kidney stones were twice as likely to have serious kidney problems later in life when compared ...

The Atlantic Ocean hurricane season spawned two hurricanes this week and NASA satellites have been monitoring them and providing valuable data to forecasters. NASA's TRMM satellite saw very heavy rainfall and powerful towering thunderstorms in Michael when the storm became a hurricane. Michael's wind speeds more than doubled in 24 hours and it is now a major hurricane on the Saffir-Simpson scale. Tropical Storm Michael became a hurricane on Sept. 5 and NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed by and collected data on rainfall and cloud heights. ...

Sorting good data from bad is critical when analyzing microscopic structures like cells and their contents, according to researchers at Rice University. The trick is to find the right window of time through which to look. A new paper by the Rice lab of Angel Martí, an assistant professor of chemistry and bioengineering, offers a methodology to optimize the sensitivity of photoluminescent probes using time-resolved spectroscopy. Martí and co-author Kewei Huang, a graduate student in his group, found their technique gave results nearly twice as good as standard fluorescence ...

Adding the monoclonal antibody bavituximab to docetaxel chemotherapy doubles overall response rate and improves progression-free survival and overall survival in late-stage non-squamous, non-small cell lung cancer (NS-NSCLC) patients who have already received one prior chemotherapy regimen, according to research presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung ...

This press release is available in French.Researchers from the Guy Rouleau Laboratory affiliated with the CHUM Research Centre and the CHU–Sainte-Justine Research Centre have discovered the genetic cause of a rare disease reported only in patients originating from Newfoundland: hereditary spastic ataxia (HSA). This condition is characterized by lower-limb spasticity (or stiffness) and ataxia (lack of coordination), the latter leading to speech and swallowing problems, and eye movement abnormalities. The disease is not deadly, but people start developing gait problems ...

Stage I, non-small cell lung cancer (NSCLC) patients who received radiation therapy have an increased median survival of 21 months compared to 16 months, and the percentage of patients who receive no treatment declined from 20 percent to 16 percent, respectively, when comparing the two eras evaluated, 1999-2003 and 2004-2008, according to detailed analysis of the SEER-17 (Surveillance Epidemiology and End Results, National Cancer Institute) national database presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the ...

Stage III non-small cell lung cancer (NSCLC) patients treated with surgery and/or radiation therapy have a significantly reduced risk of developing brain metastases if they also receive prophylactic cranial irradiation (PCI); however, this study did not show an improvement in overall survival with PCI, according to research presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the ...

TORONTO, Sept. 6, 2012 – Imagine that the players on your favourite football team were smaller than their opponents, and had to play without helmets or pads. Left defenseless, they would become easy prey for other teams. Similarly, changes in Canadian lake water chemistry have left small water organisms vulnerable to their predators, which may pose a serious environmental threat, according to a new study. "At low calcium levels the organisms grow slower and cannot build their armour," says study lead author Howard Riessen, professor of biology, SUNY College at Buffalo. ...

Treatment with pemetrexed, carboplatin and bevacizumab followed by maintenance pemetrexed and bevacizumab (Pem+Cb+B) is no better than standard therapy with paclitaxel, carboplatin and bevacizumab followed by bevacizumab (Pac+Cb+B) in patients with advanced non-squamous non-small cell lung cancer (NS-NSCLC), according to research presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association ...

SAN ANTONIO (Sept. 6, 2012) — RSV, a virus that causes respiratory infections in infants and young children, selectively kills cancer cells while leaving healthy cells alone, researchers from the School of Medicine at The University of Texas Health Science Center San Antonio said. Santanu Bose, Ph.D., of the School of Medicine, is the inventor on a pending U.S. patent of RSV as an oncolytic therapy. This represents a new use for the virus. Bandana Chatterjee, Ph.D., of the School of Medicine and the South Texas Veterans Health Care System, is the co-inventor. Oncolytic ...

Every ten years or so, someone will make the observation that there is a lack of political diversity among psychological scientists and a discussion about what ought to be done ensues. The notion that the field discriminates against and is skewed toward a liberal political perspective is worthy of concern; scholars, both within and outside the field, have offered various solutions to this diversity problem. As psychological scientists Yoel Inbar and Joris Lammers point out, however, we have few of the relevant facts necessary to understand and address the issue. In ...

Pick your poison: sun exposure that leads to skin cancer or low physical activity that leads to obesity? In fact, a University of Colorado Cancer Center study published this week in the journal Preventing Chronic Disease shows that parents' concern about skin cancer doesn't make them keep their kids indoors. "Actually, our hypothesis was the opposite – that if parents were concerned about skin cancer they wouldn't let their children go out as much," says Alexander Tran, summer fellow working with Lori Crane, PhD, CU Cancer Center investigator and chair of the Department ...

GAINESVILLE, Fla. — University of Florida scientists publishing the first study on butterflies and moths of Guantanamo Bay Naval Station have discovered vast biodiversity in an area previously unknown to researchers. Appearing in the Bulletin of the Allyn Museum Sept. 5, the study creates a baseline for understanding how different plant and animal species have spread throughout the Caribbean. "Biodiversity studies are extremely important because they give us clues about where things were and how they evolved over time so we can better understand what may happen in ...

CAMBRIDGE, MA -- Competition is a strong driving force of evolution for organisms of all sizes: Those individuals best equipped to obtain resources adapt and reproduce, while others may fall by the wayside. Many organisms — mammals, birds and insects, for instance — also form cooperative social structures that allow resources to be defended and shared within a population. But surprisingly, even microbes, which are thought to thrive only when able to win the battle for resources against those nearest to them, have a somewhat sophisticated social structure that relies on ...

A study of survival data for Stage III, non-small cell lung cancer (NSCLC) patients at the University of Maryland's Greenebaum Cancer Center in Baltimore indicates that marital status and race can significantly impact patient survival rates, according to research presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung Cancer (IASLC), and The University of Chicago. This ...

Analysis of non-small cell lung cancer (NSCLC) patient records in the California Cancer Registry (CCR) database during the 20-year period of 1988-2008 indicates that Hispanics/Latinos with NSCLC have a higher overall survival compared to non-Hispanic white patients, according to research presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung Cancer (IASLC), and The ...

Crizotinib is effective in shrinking tumors in patients with anaplastic lymphoma receptor tyrosine kinase (ALK) positive non-small cell lung cancer, a cancer commonly found in people who never smoked, and should be the standard of care for advanced stages of this disease, according to research presented at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology. This symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung Cancer (IASLC) ...

COLLEGE PARK, Md. - From a public policy point of view, the national debt accumulation since President Obama took office is largely a result of policies put in place prior to his inauguration, says a new analysis by University of Maryland expert Philip Joyce. He adds that Obama's policies will make little impact in the debt over the next decade. "The best that can be said about presidential fiscal policies thus far is that they would slow the bleeding, but they neither would stop it nor would they do much to heal the patient," Joyce says. The size of the debt has been ...

Today, technicians in Minnesota will begin to position the first block of a detector that will be part of the largest, most advanced neutrino experiment in North America. The NuMI Off-Axis Neutrino Appearance experiment – NOvA for short – will study the properties of neutrinos, such as their masses, and investigate whether they helped give matter an edge over antimatter after both were created in equal amounts in the big bang. The experiment is on track to begin taking data in 2013. "This is a significant step toward a greater understanding of neutrinos," said Marvin ...

BUFFALO, N.Y. -- We hear all the time that we need to get off the couch, stop watching TV and get moving. But what if watching TV under specific conditions could actually provide the mental boost you need to tackle a difficult task? A new paper that describes two studies by Jaye Derrick, PhD, research scientist at the University at Buffalo's Research Institute on Addictions, found that watching a rerun of a favorite TV show may help restore the drive to get things done in people who have used up their reserves of willpower or self-control. "People have a limited pool ...

ENERGY – Revolutionary heat pump . . . Oak Ridge National Laboratory and Oklahoma's ClimateMaster Inc. have collaborated to develop a ground source heat pump that can reduce a homeowner's electric bill by up to 60 percent. The Trilogy 40 is the first geothermal heat pump certified by the Air Conditioning, Heating and Refrigeration Institute to achieve a space cooling efficiency rating in excess of 40 EER (energy efficiency ratio). An EER rating of 13.5 is typical of conventional heat pumps. For a family living in a 2,600-square-foot well-insulated home, that translates ...

URBANA – As a college student, you may be happy simply not to have gained the "Freshman 15." But a University of Illinois study shows that as little as 1.5 pounds per year is enough to raise blood pressure in that age group, and the effect was worse for young women. "In our study, a small weight gain was enough to raise a college student's systolic blood pressure by 3 to 5 points. If young people continue to gain 1.5 pounds a year and think it doesn't matter, they're misleading themselves and increasing their risk for heart disease," said Margarita Teran-Garcia, a U of ...

A new study published in a special issue of Substance Abuse finds that recovering alcoholics who help others in 12-step programs furthers their time sober, consideration for others, step-work, and long-term meeting attendance. These novel findings are from a 10-year, prospective investigation led by Maria Pagano, PhD, associate professor of psychiatry at Case Western Reserve University School of Medicine and principal investigator of the "Helping Others" study. Dr. Pagano and colleagues evaluated the decade long of treatment outcomes using data from a single site in ...

Boston, Mass. - Sepsis, or bacterial infection of the bloodstream, is a grave, hard-to-diagnose threat in premature newborns in the NICU. Even when it's detected and treated with antibiotics, its inflammatory effects can harm fragile babies' development. Now, researchers at Boston Children's Hospital have modeled the effects of sepsis on the unique newborn immune system, using mice. They and others have begun using the model to identify diagnostic markers and better treatments. The new model is described September 6 in the online open-access journal PLOS ONE (available ...
