Aloe Vera Fluid May Enhance Survival After Hemorrhagic Shock

Results suggest the fluid could increase survival in trauma patients and wounded soldiers

A novel resuscitation fluid derived from aloe vera that was developed by researchers at the University of Pittsburgh’s McGowan Institute for Regenerative Medicine has the potential to save the lives of patients with massive blood loss, according to results of an animal study published in the August edition of the medical journal Shock. The findings could have a significant impact on the tr

Stroke Prevention Program for Kids Shows Major Success

The incidence of first stroke in children with sickle cell disease in California has taken a nose-dive since 1998 and the likely reason is a program developed at the Medical College of Georgia to identify and treat kids at risk, a new study says.

The study by the University of California, San Francisco published in the current issue of Blood, looked at nearly two-thirds of the state’s children at high risk for stroke. Researchers found better than an 80 percent reduction in first s

Understanding Babies’ Thoughts Before They Speak

Babies as young as five months old make distinctions about categories of events that their parents do not, revealing new information about how language develops in humans. The research by Sue Hespos, assistant professor of psychology at Vanderbilt University, and Elizabeth Spelke, professor of psychology at Harvard University, was published in the July 22 issue of Nature in the article “Conceptual precursors to language.”

“It’s been shown in previous studies that adults actually categorize

URI oceanographer studies seasonal changes in coastal ’jet’ south of Block Island

University of Rhode Island Graduate School of Oceanography physical oceanographer David Ullman and University of Connecticut physical oceanographer Dan Codiga have studied the processes giving rise to a coastal current jet that forms in the Atlantic Ocean south of Block Island. Although the commonly accepted scientific view has been that the flow along the southern New England continental shelf is steady on seasonal timescales, recent collection and analysis of long-term current records as part of a

Organic vs. Conventional Produce: Key Health Insights Revealed

New research on specific sample groups shows some organic produce may have an added health benefit over conventionally grown counterparts, according to researchers presenting at the Institute of Food Technologists Annual Meeting and Food Expo. But inherent inconsistencies associated with organic farming make general comparisons inappropriate.

In her study of organic and conventionally grown tomatoes, Alyson Mitchell, a food chemist at University of California at Davis, found organic tomato

Aging Population, Longer Survival with Disease Magnify Heart Failure “Epidemic”

Heart failure is the leading cause of hospitalization among persons 65 and older, and admissions for its symptoms have increased by 155 percent over the last 20 years. This raises concerns about an epidemic that involves more new cases of heart failure. But improved survival with heart failure, not an increase in disease rates, is responsible for this epidemic of hospital admissions, according to findings of a Mayo Clinic study published this week in the Journal of the American Medical Association.

Ultrasound Accreditation Enhances Quality of Practice Standards

American Institute of Ultrasound in Medicine (AIUM) accreditation increases the quality of ultrasound practice, according to an article published in the August 2004 issue of the Journal of Ultrasound in Medicine. The article, “The Accreditation of Ultrasound Practices: Impact on Compliance With Minimum Performance Guidelines,” by Alfred Z. Abuhamad et al, concludes that “ultrasound accreditation adds value to the practice by improving compliance with AIUM minimum standards and guidelines for the pe

Broader Chemotherapy Strategy Enhances Breast Cancer Treatment

In the first comprehensive survey of gene activity in each cell type composing normal and malignant breast tissue, scientists at Dana-Farber Cancer Institute have identified genes in non-cancerous supporting cells that can spur the growth of breast cancer cells.

The findings suggest that aiming chemotherapy at both cancer cells and their genetically normal cellular “microenvironment” might improve the success of breast cancer treatment.

In the July 20 issue of Cancer Cell, the re

Research shows aspirin therapy didn’t work in almost half of stroke patients studied

Northwestern Memorial research shows an aspirin a day may not keep strokes away

Northwestern Memorial researchers have found that nearly half of patients who suffered a stroke or transient ischemic attack (TIA) after having been committed to aspirin therapy were “aspirin resistant,” meaning the aspirin wasn’t producing the antiplatelet (blood-thinning) effect needed to avoid these health threats. Aspirin resistance increased when patients had been taking baby (81 mg) or enteric coa

New Insights on Peutz-Jeghers Syndrome and mTOR Inhibitors

A study in the July 2004 issue of the medical journal Cancer Cell provides scientists with new insights into a rare genetic disorder known as Peutz-Jeghers Syndrome (PJS), and suggests that a class of drugs called mTOR inhibitors may be useful for the treatment of the condition, which has been linked to cancers of the gastrointestinal tract, lung, breast, uterus and ovaries. Caused by a mutation that inactivates the tumor suppressor gene, LKB1, PJS is characterized by the development of pigmented sp

Bladder-Sparing Treatment Offers Hope for Cancer Patients

For patients with invasive bladder cancer, treatment has typically meant an operation to remove the bladder and nearby organs. This requires up to a week in the hospital and leaves patients with a reconstructed bladder or urostomy bag.

Minimally invasive surgery combined with chemotherapy and radiation therapy has potential in some patients to cure the cancer but preserve the bladder. A new pilot study by University of Michigan Health System researchers found combining radiation therapy an

Impact of Earth’s Rising Atmospheric Carbon Dioxide Found in World Oceans

An international team of scientists has completed the first comprehensive study of the ocean storage of carbon dioxide derived from human activity, called anthropogenic CO2, based on a decade-long survey of global ocean carbon distributions in the 1990s.

The findings, along with those detailed in a companion paper on the impacts of anthropogenic CO2 on the chemistry of the oceans and the potential response of marine animals and plants to changes in CO2 levels, will be published in the July

New MRI Technique Detects Early Multiple Sclerosis Signs

An innovative study at Robarts Research Institute provides early evidence that hospital MRI scanners can be used to detect distinct brain cell abnormalities that are predictors of multiple sclerosis (MS).

In a preclinical study in rats with a disease similar to the human form, Robarts scientist Dr. Paula Foster used an injection of nano-particles of iron oxide, which exhibit magnetic qualities and can be detected by an MRI scanner.

During the acute inflammatory phase of the disease,

$100K Grant Fuels Retinal Cell Transplant Research at Utah

The University of Utah’s John A. Moran Eye Center has received a $100,000 grant from the Stephen A. and Elaine Wynn Charitable Foundation to fund continued research into retinal cell transplantation. The research is expected to help set the stage for human clinical trials of treatments for a blinding eye disease known as Retinitis Pigmentosa (RP).

The funding will support the work of Raymond D. Lund, Ph.D., the Calvin S. and Janeal N. Hatch Presidential Endowed Chair and Professor of Opht

Anxiety During Pregnancy: Impact on Child Behavior Explained

The idea that a woman’s emotional state during pregnancy affects her unborn child has persisted for centuries and has, in recent years, been supported by science. Called the “fetal programming hypothesis,” it theorizes that certain disturbing factors occurring during certain sensitive periods of development in utero can “program” set points in a variety of biological systems in the unborn child. This, then, affects the ability of those biological systems to change later in life, resulting in difficu

Migrating Birds Unlock Secrets of Sleep for Humans

A newly published study by a University of Wisconsin research team points the way to solving two of life’s seemingly eternal but unrelated mysteries: how birds that migrate thousands of miles every year accomplish the feat on very little sleep and what that ability means for humans who are seriously sleep-deprived or face significant sleep problems.

The study, published online in the July 13 issue of PloS (Public Library of Science) Biology, found that a group of sparrows studied in the l
