A three-year study using Arabidopsis thaliana aims to define the roles of protein-degrading enzymes important to wood formation. The researchers hope to identify genes that regulate this process, which could have significant implications for forest product development and our understanding of plant development.
A University of Toronto geneticist has discovered a process to clarify the relationship between bacterial pathogens and their plant hosts. By developing a functional screen, Professor David Guttman identified more type III effectors in plant pathogen Pseudomonas syringae than in any other animal or plant pathogen.
A new UCLA study finds that 'sweaty palms' syndrome is caused by a dominant gene, affecting up to 5% of the population. The disorder can significantly impact daily life and career, with symptoms including excessive sweating in hands and feet.
A study on female monkeys found that stress can reduce estrogen levels, leading to the development of atherosclerosis and increasing heart disease risk. The research highlights the importance of pre-menopausal behavioral and hormonal conditions for post-menopausal health.
The new technology uses magnetic resonance microscopy (MRM) to produce 3-D images of mice at unprecedented resolution, revolutionizing the use of mouse models in understanding human disease. Digital 'Visible Mice' will enable researchers to share and analyze animals electronically, facilitating collaboration across distances.
Scientists have combined satellite measurements with model calculations to demonstrate that atmospheric aerosols increase cloud brightness, leading to greater reflection of sunlight and potential cooling of the climate. This effect should be accounted for in assessing global climate change.
A study published in the American Journal of Psychiatry found that nearly all antidepressant trials exclude patients with mild depression, anxiety disorders, or other psychiatric problems. This limits the generalizability of trial results and may lead to unjustified exposure of risks and side effects.
Research suggests asteroids were responsible for a massive impact event 3.9 billion years ago, which destroyed older rocks and created thousands of craters across the inner solar system. This bombardment may have provided an environment conducive to pre-biotic chemistry and early life evolution.
A comprehensive study found that both prenatal and postnatal lead exposure were associated with increased antisocial behavior in children and adolescents. The researchers followed inner-city adolescents for over two decades, tracking blood lead levels and documenting delinquent behavior.
A study found that farmers with specific genetic variations in the paraoxonase gene are more likely to experience poor health after exposure to organophosphates used in sheep dip. This suggests a potential link between repeated exposure and chronic ill health.
Researchers are studying abnormal beta cell function to better understand canine and feline diabetes. They found that certain proteins play a crucial role in insulin secretion, which may contribute to the development of diabetes.
Researchers from National University of Singapore and John Innes Center discover protein RGL2 acts as molecular crossroad for seed germination. RGL2 accumulates upon imbibition and suppresses germination in absence of gibberellin, but is suppressed by GA allowing germination to begin.
The new UI Center for Research on Processes in Evolution will investigate the evolution of drug resistance in microbes and determine how specific viruses choose their hosts. This research could help identify patterns in evolution and constraints, shedding light on nature's workings and future disease threats.
A study found that genetic testing can identify HIV patients at risk of a life-threatening hypersensitive reaction to the antiretroviral drug abacavir. Patients with the HLA-B*5701 allele were over 100 times more likely to experience the adverse reaction.
A new study published in The Lancet suggests that abacavir-containing regimens are more effective than zidovudine/lamivudine in children with HIV-1 who have not previously been treated. This finding could provide a good NRTI backbone for use with protease inhibitors and non-nucleoside reverse-transcriptase inhibitors.
A team of researchers discovered a protein that controls animal cell fusion, which is crucial for proper development and tissue formation. The study found that mutations in this gene lead to birth defects and organ malformations, highlighting the importance of understanding the fusion mechanism.
A recent study found that nearly 33% of women misdiagnose themselves with vulvovaginal candidiasis, a yeast infection, while 19% actually had bacterial vaginosis. Dr. Daron G. Ferris suggests that women first see their doctor for confirmation before using over-the-counter treatments.
Researchers at Johns Hopkins Medicine have developed a novel imaging technique to detect tiny tumors that cause a rare bone disorder. The method, which uses radioactive pentetreotide to identify tumor locations, has correctly pinpointed tumors in five of seven patients with oncogenic osteomalacia.
The study found TMC125 effective against highly NNRTI-resistant HIV strains in patients failing treatment. The drug showed no signs of resistance development and was well-tolerated during the trial.
Chemists at Ohio State University have created the first-ever compounds of uranium bonded to atoms of three so-called
A study published in Medical Care found that managed care plans continuing to serve older Americans under the Medicare program tend to provide higher quality service. The research suggests that higher quality performance is associated with lower rates of withdrawal from the program.
Researchers used refined techniques to study minerals from meteorites, revealing a 20-million-year estimate for the Earth's formation. The new figure is based on careful separation of minerals and isolation of radioactive forms of niobium and zirconium.
The book examines California's commercial and recreational fisheries, discussing natural history and ecological health. With over 125 leading scientists contributing to the report, it provides valuable insight into the relationship between marine resources and economic prosperity.
A recent survey of over 500 first-time mothers found that 35% experienced urinary incontinence and 4% suffered from faecal incontinence. The study suggests that damage to the pelvic floor may occur during pregnancy as well as childbirth, highlighting the need for improved maternity care.
Researchers have identified a region of chromosome 4 associated with pancreatic cancer, which may lead to earlier identification and treatment. The discovery has potential implications for understanding the disease's causes and developing new treatments.
The University of Illinois Chicago has received a five-year, $7 million NIH grant to study the mechanisms of fertility and infertility. Researchers will investigate hormone regulation, immune response, and other factors contributing to endometriosis and infertility.
A UCLA-led team of chemists and engineers has developed a transparent plastic that can mend itself when heated, offering potential use in industries such as electronics, radar and communications. The material, called Automend, retains 60% of its original strength after healing.
A large family study identified a specific genetic marker on chromosome 4 associated with inherited pancreatic cancer. The discovery sheds light on the disease's development and may lead to new prevention and treatment strategies.
Researchers found that a specific strain of Staphylococcus aureus is linked to severe pneumonia in children, particularly those with influenza-like illness. The study highlights the need for vigilance in monitoring and treating these cases, as younger patients are at higher risk of death.
