Researchers at Johns Hopkins Medicine developed a new computer model that accurately reflects how the brain uses experience to improve motor control. The brain creates a map of forces expected in the world by multiplying electrical signals from nerve cells.
The guidelines recommend five medication types to treat neuropathic pain, including gabapentin, lidocaine patches, and narcotics. Neuropathic pain affects 4-6 million people in the US, caused by nerve damage from conditions like shingles, diabetes, and cancer.
A study using fMRI found that children with seriously delayed speech have higher levels of right brain lobe activity and less total brain activation than age-matched children. This suggests that speech-delayed children may be less receptive to language as they age, highlighting the importance of early intervention.
The article discusses a study on women's experiences with cervical cancer screening and finds that most are reluctant to reduce the frequency of Pap tests. Meanwhile, another study analyzes exercise stress test results for predicting cardiac mortality in older adults.
The Royal Society of Chemistry hosted a plenary lecture on green and sustainable chemistry, featuring speakers from industry and academia. Key highlights include collaborations between sectors, innovative technologies for reducing waste and consumption, and the importance of information infrastructure.
The American Association for the Advancement of Science (AAAS) honored six reporters for their outstanding contributions to science journalism between July 1, 2002 and June 30, 2003. The winners used science storytelling to convey complex issues and make them accessible to the general audience.
A study found that gray squirrels are essential for germination of black walnut trees due to their scatter hoarding behavior, while red squirrels' larder hoarding practice hinders seed dispersal. The researchers suggest changing land-use practices to maintain healthy forest connectivity.
The study found that infants exposed to magnesium sulfate had lower rates of pediatric mortality, cerebral palsy, and substantial gross motor dysfunction compared to those not receiving the treatment. However, these differences were not statistically significant, and further trials are necessary to confirm the findings.
A study found that regionalizing certain surgical procedures would not significantly increase travel time for patients, with most needing less than 30-minute additional trips. The study suggested implementing volume standards without imposing unreasonable burdens on rural area residents.
A study found that people with Alzheimer's disease show increased activation in the default network, a set of interconnected brain areas responsible for passive mental processes. This could be an attempt to compensate for memory problems caused by normal aging or Alzheimer's.
The partnership aims to address unequal burden of cancer on minority communities by providing access to clinical trials and strengthening cancer research programs. The collaboration will enhance cancer treatment capability and produce healthier outcomes for patients in South Central Los Angeles.
Scientists have directly observed RNA 'proofreading' for the first time using nanotech instruments, revealing a backtracking motion that corrects genetic errors. The study provides strong evidence for the self-correcting mechanism of RNA polymerase, improving our understanding of gene expression and potentially informing human health.
Researchers at NYU School of Medicine developed a new technique to measure brain volume, identifying healthy individuals who would later develop memory impairment. The study found that the medial-temporal lobe shrank considerably more in people with Alzheimer's disease compared to those without it.
Researchers determined the structure and behavior of a protein receptor complex in E. coli, revealing a 'two-receptor approach' to bring substances into the cell's cytoplasm. This discovery could provide insights into cellular metabolism and how proteins are transported across membranes.
Temple researchers mapped out early embryo development and found that clones replicate the process entirely at this stage. However, cloned embryos bear characteristics of both an embryo and adult cell, leading to slow and incomplete development.
A study by University of Michigan doctors found that gender is the biggest predictor of chaperone use, with male doctors more likely to have a nurse or assistant present. Regional differences also exist, with Southern doctors using chaperones more frequently than those in the Midwest.
Researchers at UCF are studying different learning techniques to train people to pick out guns, knives and other threatening objects as they pass through airport X-ray machines. The goal is to make screeners more accurate and faster, leading to improved safety and convenience for travelers.
A digital imaging system is being developed to automate the inspection process at a bakery, allowing for faster and more accurate quality control. The system uses computerized vision technology to identify imperfections in bread rolls and automatically remove them from production lines.
Researchers estimated that only one further case of vCJD in Ireland is likely, based on exposure to BSE-infected beef. The study used data from the UK to calculate the future risk to the Irish population.
A randomized, double-blinded study found no differences between olanzapine and haloperidol in reducing schizophrenia symptoms or improving quality of life. Olanzapine was associated with higher costs due to its high price tag, despite slightly better cognitive status and less restlessness.
A study found that nearly 70% of women aged 50-64 and 40% of those 85-90 had received mammograms in the last two years, despite limited benefits. The research suggests that over-screening can be costly and wasteful, particularly for healthy individuals.
A large study found warfarin to be highly effective in reducing the risk of ischemic stroke and thromboembolism in patients with atrial fibrillation, even among those at moderate to high risk for stroke. Warfarin was also associated with a reduced risk of all-cause mortality.
Researchers analyzed DNA samples from 127 patients with gastrointestinal stromal tumors (GISTs) to determine if a KIT tyrosine kinase mutation was present and its impact on Gleevec response. Patients with favorable lab results had an 84 percent chance of partial remission, while those with unfavorable results did not respond.
Researchers identified several factors that may enable or prevent HIV transmission through breastfeeding, including the hostile environment of saliva and immune activation in the gastrointestinal tract. Protective factors include natural killer cells, natural antibodies, and specific antibody responses.
Researchers have identified a new 'off switch' that limits the duration and intensity of T-cell activation, potentially treating autoimmune diseases. The IL-27 cytokine regulates immune cell growth and functions, offering a universal checkpoint for the immune system.
A study of 327 infants found chorioamnionitis increases CP risk by 4 times, with maternal black ethnicity and older age also associated. Chorioamnionitis was present in 14% of cases and controls.
A $2 million sorghum genome grant is funding a project to train students from diverse backgrounds in genetic analysis and presentation. The goal is to attract more scientists from underrepresented groups to plant genomics research, promoting diversity in the field.
Researchers used MRI to study 45 healthy elderly patients and found that progressive brain atrophy was predictive of future cognitive decline. The medial temporal lobe, a small but critical brain region, showed the most significant correlation with memory loss.
