A study published in The Lancet found that delaying umbilical cord clamping for two minutes at birth significantly increases a child's iron status, particularly among those with low birth weights or iron-deficient mothers. This efficient and low-cost method can help prevent iron deficiency before 6 months of age.
Bioengineering researchers found that cells use pairs, trios, and combinations of up to 13 transcription factors to regulate distinct sets of genes. The study predicts 980 as-yet-undiscovered transcription factor-gene binding interactions.
Researchers found that teenage girls who engage in self-harming behaviors have lower levels of serotonin, a hormone and brain chemical, in their blood. They also have reduced levels in the parasympathetic nervous system's respiratory sinus arrhythmia, which is associated with anxiety and depression.
In a study by Udo Groeger and Lutz Wiegrebe, vampire bats were taught to associate different human breathing patterns with cattle blood dispensers. The bats demonstrated the ability to recognize clips of humans breathing at rest and during physical strain, while human participants struggled to do so.
Researchers have identified a signal transduction process regulating stem-cell division, which could lead to drugs stimulating endogenous cell production. The discovery may help treat conditions such as stroke and Parkinson's by promoting the formation of new nerve cells.
Researchers compared wild rodents to laboratory rodents and found that wild animals had higher levels of antibodies associated with allergy and autoimmune disease. This suggests that a lack of exposure to microbes in modern environments may contribute to these conditions.
Researchers have discovered the structure of a protein called nucleoprotein, which helps viruses like rabies evade the human immune system. The protein acts as a 'clamp' to protect the virus RNA from degradation by host enzymes.
Research suggests that phosphodiesterase-5 inhibitors (PDE-5i) have mostly positive effects on various organ systems, including the blood, heart, lungs, and brain. The drugs are effective in treating erectile dysfunction even for men with diabetes, high blood pressure, and ischemic heart disease.
The new guidelines provide practical recommendations for evaluating patients with heart murmurs, preventing endocarditis, and treating concomitant coronary artery disease. The guidelines include more precise definitions of mild, moderate, and severe valvular disease, which may prompt earlier referrals for surgery.
Researchers discovered high levels of melatonin in Nebbolo, Merlot, Cabernet Savignon, Sangiovesse, and Croatina grapes. The study suggests that melatonin content can be enhanced by treating vines with a plant vaccine Benzothiadiazole.
The study demonstrates an extremely high rate of prediction accuracy (95%) in a very complex pathogen, the vaccinia virus. Bioinformatics was able to reveal the vast majority of epitopes that trigger an effective immune response against the virus.
A new study reveals that Pycnogenol, a French maritime pine bark extract, significantly reduces hyperactivity and improves attention, concentration, and motor-visual coordination in children with ADHD. The study's findings suggest that Pycnogenol may serve as a safe and effective treatment for children diagnosed with ADHD.
Researchers discover altered activity in NRG1-erbB4 and NMDA receptor pairs, suggesting a relationship between the two and contributing to schizophrenia symptoms. The study's findings provide new insights into the molecular mechanisms underlying the disease.
Researchers at the University of British Columbia have successfully prevented Huntington disease in a mouse model by blocking the cleavage of the mutant huntingtin protein. This discovery provides new hope for effective treatment and potentially a cure for the devastating disorder.
Researchers found that eliminating a molecular switch allows immune cells to enter the central nervous system (CNS), leading to symptoms similar to multiple sclerosis. Eliminating this switch prevents destructive immune cells from entering CNS tissue, keeping mice healthy.
A Northwestern University research team has developed a three-dimensional imaging technique that enables the study of fuel cell microstructure. This will help improve fuel cell performance and lifespan by revealing nanometer-scale features.
The Idaho Bureau of Land Management and weed control groups use new software to analyze NASA satellite imagery and target areas for cheatgrass treatment. The technology helps land managers be smarter in using their resources, improving the effectiveness of weed control efforts.
Researchers discovered that Shewanella oneidensis MR-1 bacteria protect metals like copper, aluminum, and mild steel from corrosion. The study found increased resistance to electrical currents and reduced pitting in metals exposed to the bacteria.
A new study by Vanderbilt University researchers suggests that helping children handle stress and emotions may help alleviate stuttering. The study found that children who stutter are more likely to be emotionally aroused in everyday situations, have difficulty controlling their attention, and take longer to calm down.
Rochester Institute of Technology and color scientist Roy Berns have developed a practical approach to eliminate subjective lighting decisions when imaging artwork. The five-year project will create an instrument to capture geometric and spectral information of artwork, using mathematical models to predict properties.
Scientists from the University of Wisconsin-Madison have made a fundamental discovery about RNA synthesis in E. coli, shedding light on how bacteria regulate gene expression. The study found that a specific region within DNA promoters makes contact with RNA polymerase, but not at promoters for genes involved in ribosomal RNA production.
The HPV vaccine protects against two types of HPV responsible for 70% of cervical cancer cases. Targeted school-based vaccination clinics are proposed as an effective strategy to reach at-risk African American females.
In a breakthrough study, researchers found that nerve cells in the olfactory bulb detect individual chemical compounds in odors, rather than perceiving complex mixtures as single objects. The brain integrates these signals to form a recognizable scent, much like combining multiple melodies to hear a symphony.
