A study by Harvard Medical School found that elderly patients with acute myocardial infarction (AMI) covered by non-profit health maintenance organizations (HMOs) received higher use of lifesaving therapy and emergency transportation compared to those with fee-for-service insurance. HMOs improved access to timely urgent care, particula...
Researchers at UB used a fluorescent probe to track the uptake of AN-152, a cancer drug linked to a peptide hormone carrier, by human breast-cancer cells. The study provides evidence that AN-152 directly enters cancer cells, accumulates in the nucleus and associates with chromosomes.
The University of Michigan School of Public Health is leading a $12.5 million project to improve the quality of life for children with asthma. The initiative aims to establish local coalitions that implement programs reducing hospital stays, emergency room visits, and enhancing asthma management. Faculty from U-M's asthma research team...
A Cornell University study of over 1,700 six- and seven-year-olds found that single mothers' education levels were more important than family income for their children's math, reading, and vocabulary scores. Strong links between a mother's ability level and her child's academic performance were seen in white, black, and Hispanic families.
New research from UCSF reveals that HIV patients with high CD4+ counts are still at risk of opportunistic infections such as CMV retinitis. The studies found a relationship between the effectiveness of anti-CMV therapy and HAART, highlighting the need for careful consideration in treatment strategies.
The Microbe-Mineral Group at Virginia Tech aims to discover conditions under which microbes release nutrients or contaminants from mineral surfaces. Researchers hope to advance bioremediation and control unwanted releases of phosphorus and other minerals.
The Max Planck Institute for Gravitational Physics has released the public beta of the Cactus Computational Toolkit 4.0, a collaborative environment for solving partial differential equations in physics and engineering. The toolkit allows individual scientists to plug their own computing applications into a modular framework, enabling ...
A study suggests that frequent dental visits can eliminate gingival overgrowth recurrence in patients taking nifedipine for high blood pressure. This regimen significantly reduces gum swelling and associated health risks.
Researchers found that increasing humus content can increase quinoline's movement to groundwater, but mineral interactions play a key role. The study suggests that strongly bound pollutants may still be broken down by microorganisms.
The University of Wisconsin-Madison has launched a Center for the Study of Mind-Body Interaction to investigate how emotions affect physical health. The center will focus on five projects, including examining resilience in older women and the impact of meditation on brain activity.
A recent study published in Nature Medicine has found that gamma/delta T cells are essential for regulating airway hyperresponsiveness, which is characterized by an exaggerated response to stimuli. The research suggests that these cells have a suppressive effect on airway constriction and may be a key target for future treatments.
Researchers have identified 15 M. tuberculosis genes expressed only when the bacteria are growing in macrophages, key disease-fighting cells. These genes play important roles in pathogen metabolism, propagation and self-protection, potentially leading to new drug targets or vaccines.
Researchers have identified 109 mariner elements in the human genome, which may contribute to genetic disorders such as Charcot-Marie-Tooth disease and hereditary neuropathy. The study's findings suggest that mariner transposons could be a hotspot for genetic change and error.
Researchers at University of Washington found that couples who later divorced displayed significantly more negative emotions and words in their initial discussions compared to those who stayed married. The study suggests that learning how to soften one's approach and improve emotional connectedness can help prevent divorce.
Recent studies have found that high cortisol levels might be a cause of depression, potentially leading to new antidepressant drug strategies. Cortisol-lowering drugs have shown promise in reducing depressive symptoms, especially in patients with high cortisol levels.
Outbreaks of toxic Pfiesteria microorganisms in recreational waterways can have significant impacts on summer tourism and seafood sales. According to a survey of 3,500 coastal residents, a Pfiesteria outbreak could reduce tourism by at least 40% and lead to nearly two-thirds of respondents eating less locally harvested seafood. Consume...
The University of Maryland School of Medicine will receive $24 million over six years from Novartis Pharma AG to discover new treatments for schizophrenia. The partnership aims to find ways to treat patients with 'negative' symptoms, which are limited in emotional expression and social functioning.
The consortium aims to collect medical information and genetic material from 400 families nationwide with AS to identify additional genes associated with its pathogenesis. Researchers will conduct genome-wide searches and map genes linked to AS outside of the MHC.
Scientists have found that the gene order in Arabidopsis, a model eudicot, is not preserved in rice, a model monocot. This discovery reveals an evolutionary divide between dicots and monocots, cautioning against using Arabidopsis genome for understanding cereal crops like rice and wheat.
Researchers at Michigan Technological University found that metal contaminants in Lake Superior sediments primarily come from native ore deposits, not atmospheric sources. High concentrations of mercury were detected, associated with copper and silver deposits.
Researchers have successfully sequenced human chromosome 17 using a microdevice fabricated from glass wafers, demonstrating a bright future for convenient and low-cost sequencing machines. The device holds 500 sequencing machines on a single chip, making it a significant breakthrough in DNA sequencing technology.
A study found that despite comprehensive treatment, four patients became infected with HIV at least six months after initial exposure due to ongoing contact with infected partners. Counseling strategies targeting misconceptions about transmission are crucial to preventing future infections.
Researchers at Yale University have found that healthy bullfrog tadpoles can distinguish the odors given off by infected animals and keep their distance. This ability may be widespread among animals, enabling them to avoid diseases and reducing the spread of infection.
A new method enables cheap and simple manufacture of customized DNA chips, revolutionizing genetic analysis and research. This technology can help diagnose genetic diseases and accelerate drug discovery, while reducing production costs.
