Research on plasminogen-related growth factors has shed light on their role in mammalian development, tumorigenesis, and angiogenesis. The symposium explores the evolution of these growth factors and their interactions with other molecules, highlighting their importance in various biological processes.
A two-year study found that moderate air pollution can decrease lung function in adult hikers, even at relatively low ozone concentrations. Hikers with a history of asthma or wheezing experienced more pronounced declines.
A study at the University of Toronto has discovered a biological basis for phantom sensations experienced by amputees. The researchers found that neurons in the brain that used to represent sensation in the lost limb remain functional and are now driven by stimulation of other body parts, usually the part closest to the amputated limb.
This book brings together international specialists to discuss the genetic structure of telomeres, telomerase function, and their importance in aging and cancer. The chapters cover topics such as telomere length regulation, chromosome end replication, and telomerase repressor genes.
Researchers at USC identified signals in the cerebellum and inferior olive that cause blocking, a phenomenon where animals fail to associate new stimuli with learned responses. Blocking prevents distraction from redundant or erroneous signals, ensuring efficient learning.
Researchers have identified a new tick-borne disease in North Carolina and the Southeast that is distinct from Lyme disease. The disease, caused by an unknown organism, produces symptoms similar to ehrlichiosis but without a telltale rash. Investigation led by Dr. Kathryn Kirkland suggests the infection can be cured with antibiotics.
A population association study found a higher percentage of the 7 repeat allele and 7+ genotype in ADHD children compared to controls. The study also identified significant positive results from a family-based approach, providing additional evidence for an association between DRD4 gene and ADHD.
Scientists have identified specific brain regions linked to tinnitus, a condition with no known cause or effective treatment. The study's findings raise hopes for developing treatments and possibly even a cure.
A study by NIMH researchers suggests that female sex hormones trigger PMS symptoms, but the susceptibility to these symptoms in some women remains unexplained. Researchers found no differences between women with PMS and those without when hormone levels were artificially manipulated.
A unique strategy aims to use computer-examined variables and prescribe chemical regulations for specific areas to benefit the environment and agriculture. The nation's first 'smart' environmental regulations for ground water contamination by agricultural runoff are being created as part of Indiana's pesticide management plan.
The new welfare and immigration reform acts are likely to produce unintended consequences, including reduced legal immigration and increased incentives for illegal immigrants. Farm employment in rural California is also linked to poverty and a vicious cycle of rural poverty, with immigrants becoming trapped in low-paid labor.
Numerical simulations by U of T physicists suggest sea-level changes exceeding 100 meters can occur, contradicting previous assumptions linking them to ocean floor elevation changes. The 'wobbling' of the Earth's rotation axis produces regional sea-level variations, requiring a reevaluation of long-term climate studies.
