Researchers distinguish a new type of leukemia called mixed-lineage leukemia (MLL) that is genetically different from acute lymphoblastic leukemia (ALL). The study used DNA microarrays to compare gene expression profiles and found clues about the origin of MLL, suggesting it is caused by arrested maturation of lymphocytes.
A new study found that Topamax significantly reduced the severity of manic symptoms in patients with bipolar disorder, with 70% experiencing improvement. The medication was well-tolerated, with no significant weight gain and fewer side effects compared to traditional treatments.
Two studies examine the link between sex hormones and coronary artery spasm, finding that estrogen levels during menstruation affect blood vessel function. Automated external defibrillators are also shown to be safe and easy to use by trained laypersons, paving the way for potential home sales.
Researchers at the University of Delaware have developed a portable detection platform that can detect chemical and biological weapons using infrared spectroscopy. The device, about the size of a large shoebox, can identify even small amounts of agents in solid, liquid or vapor phases.
Researchers have created a novel method to measure soil fertility using Mason jars, which can detect chemical fractions that feed corn plants. The Illinois N Test uses a combination of heating and titration to determine nitrogen content in the soil.
Chemical oceanographers at the University of Rhode Island used naturally occurring radium to estimate ground water input to coastal systems. The study found that ground water was a significant source of radium in Rhode Island salt ponds.
Researchers at the University of Illinois found a statistical correlation between weak polar vortices and severe cold outbreaks. The study proposes a dynamical mechanism where stratospheric forcing stimulates pre-existing modes of variability in the troposphere.
Researchers found that asthmatic children from urban environments are not using preventive medications and devices correctly, and are not adhering to NHLBI guidelines during asthma flare-ups. This is particularly concerning given the high risk of developing asthma in African American children.
The WTC's design had several vulnerabilities that made it susceptible to collapse, including flimsy floor trusses and weak connections in the tube frame system. The impact of the jetliners shattered support columns, causing partial collapse and triggering a fire that exacerbated the damage
Researchers at the University of Illinois have developed a simple protein test to detect telomerase activity in cancerous cells of dogs and cats. The test has shown promising results in diagnosing malignant tumors in pets, with high accuracy rates compared to traditional diagnostic methods.
UT Southwestern researchers say automated external defibrillators (AEDs) can be used by anyone with minimal training, and are becoming increasingly widespread. Studies have shown that early defibrillation can dramatically improve survival rates for cardiac arrest victims.
A panel of experts recommends focusing on remission as the goal for treating depression and anxiety, rather than just partial improvement. This aims for virtual elimination of symptoms and restoration of psychosocial and occupational functioning.
Researchers at the University of Illinois have identified key factors affecting phosphorus runoff and developed management strategies to minimize its impact on lakes and streams. The team suggests adopting no-till soil conservation practices, injecting liquid manure and fertilizer into the soil just below the surface.
Undertreated asthma has a significant impact on women's lives, affecting their physical activities, relationships, and overall well-being. Many women report poorly controlled symptoms, anxiety, and worry about their condition.
Archaeologists have found a fragment of a French wine bottle made around the time of the American Revolution, confirming the existence of an old French site in Peoria, Illinois. The discovery resolves a decades-long debate over the village's location and sheds light on the life of Louis Chatellereau, a French farmer and fur trader.
A study by Northwestern University researchers found that men who smoke are more likely to experience erectile dysfunction due to the negative effects of smoking on blood vessels. The prevalence of erectile dysfunction in former smokers was similar to that of never-smokers, highlighting the long-term risks of tobacco use.
Researchers suggest a structured intermittent therapy approach, where patients receive daily doses of HAART for seven days, followed by seven days off the medication. This regimen has shown significant reductions in certain side effects, including cholesterol and triglyceride levels, without compromising treatment efficacy.
The discovery of the Jaragua Sphaero, a lizard measuring about three quarters of an inch from snout to tail, highlights the Caribbean's unique species diversity. Rapid population growth, agricultural practices, and lack of access to data contribute to the region's biodiversity loss.
A new study found that eliminating gatekeepers in health maintenance organizations (HMOs) does not necessarily increase costs. In contrast to traditional HMOs, point-of-service plans with open physician panels showed comparable spending on medical care expenditures, including physician services, hospital services, and prescription drugs.
A new study aims to determine the effectiveness of drug therapy, psychotherapy, or a combination in treating major depression in teenagers. The study, administered by Northwestern University Medical School, will enroll participants between 12-17 years old with clinician-diagnosed depression.
Scientists at Uppsala University have identified a gene that regulates mast cell survival upon allergic activation, providing hope for a novel therapy to treat allergies. Inhibition of this gene, A1, leads to the death of mast cells, decreasing their numbers and alleviating allergic symptoms.
Researchers found that groundwater in aquifers is generally older than expected based on flow velocity, due to mixing between aquitards and aquifers. This discovery has significant implications for estimating water supply yields and predicting contaminant migration rates.
Researchers have identified a molecule, GCNF, that restricts mouse cells' potency. This discovery may allow for the creation of embryonic stem cells without sacrificing embryos, opening up new avenues for research.
The newly discovered species, Sphaerodactylus ariasae, is the smallest of all 23,000 species of reptiles, birds, and mammals. The tiny lizard can curl up on a dime or stretch out on a quarter, measuring only 16mm long.
Researchers measured aerosols in clean marine conditions and under polluted conditions, revealing large concentrations of particulate material including mineral dust. The findings will help reduce uncertainties in global climate models and develop better policies.
A recent study by Washington University in St. Louis researchers attributes increased flood levels on the Missouri and Mississippi rivers to the placement of thousands of wing dams, built by the US Army Corps of Engineers in the 1930s and '40s. The structures impede water flow during floods, causing water levels to rise.
Research at Hope School found that animal-assisted therapy improved mobility, communication, compliance, and attention span in severely disabled children. The study suggested that a team effort among administrators, teachers, and staff is necessary for effective therapeutic interventions.
A randomized controlled trial found that unopposed estrogen therapy reduced atherosclerosis progression by .0017 millimeters per year in postmenopausal women. The study also showed that cholesterol-lowering drugs had a similar effect when combined with estrogen, suggesting potential benefits for cardiovascular health in women at risk.
