The new NSF report reveals that Latin American countries have made significant strides in publishing science and engineering articles. From 1988-2001, Brazil's output quadrupled and Mexico's more than tripled, while Argentina and Chile produced the most scientific articles per capita. The region's growing influence is reflected in the ...
Researchers at OHSU have determined the structural basis underlying a crucial mechanism that allows gram-positive bacteria to adapt to available energy sources. This finding could lead to the development of new antibiotics that disrupt this mechanism, making bacteria more susceptible to counter-attacks by the human body.
Researchers discovered a molecule that brings DNA polymerase alpha to replication sites, and it stabilizes the complex. This finding suggests that targeting Mcm10 may prevent cancer cells from multiplying.
Researchers at University of Manchester create graphene, the first two-dimensional fullerene, exhibiting remarkable electronic properties. The nanofabric shows potential to replace gallium arsenide in niche markets due to low energy consumption and high electron mobility.
A group of experts recommends incorporating environmental health into pediatric medical and nursing education, citing gaps in current curricula. The study aims to equip healthcare providers with tools to recognize, treat, and prevent diseases related to environmental factors.
A study found that a mitochondrial mutation may contribute to the development of metabolic syndrome, a cluster of disorders including high blood pressure and high cholesterol. Researchers discovered the link in a four-generation family affected by hypertension, hypercholesterolemia, and other conditions.
A recent study reports four cases of angiographically-confirmed stent thrombosis after elective implantation of drug-eluting stents, resulting in myocardial infarction. The authors emphasize the need for careful long-term follow-up to assess late thrombosis risk
Operations research and manufacturing techniques will improve healthcare delivery by reducing costs and enhancing quality. Techniques such as supply chain management and scheduling systems are being adopted in hospitals and blood banks to reduce delays and improve patient care.
Researchers at the University of Florida have created a living neural network using 25,000 rat brain cells, allowing it to learn and adapt like a computer. The 'brain' can now control a simulated aircraft, paving the way for potential use in flight control systems.
A single genetic mutation in mitochondrial genes has been found to be associated with multiple risk factors for heart disease and stroke, including hypertension, high cholesterol, and low magnesium levels. The researchers also discovered a link between the mutation and other conditions such as hearing loss and weakened heart muscle.
The Lancet editorial emphasizes the need for a more compassionate approach to end-of-life medical decisions, particularly in cases where parents and doctors disagree. The article advocates for arbitration as an alternative to court proceedings, citing its potential to resolve conflicts in a more constructive manner.
A study of 54 patients who underwent gastric bypass surgery found a 52% decrease in musculoskeletal complaints and a 92% reduction in fibromyalgia syndrome pain after 6-12 months. The significant weight loss resulted from stapling the stomach to create a small pouch, leading to improved function and quality of life.
A study by Johannes Schwarz and colleagues tracked molecular changes in brains of Parkinson's patients over 7.5 years using SPECT to measure dopamine transporter binding, revealing a single exponential decline rather than linear loss. This advancement enables the development of individualized treatment for advanced Parkinson's patients.
A Northwestern University team discovered that mutant Huntingtin protein aggregates bind to the proteasome machine, preventing complete degradation of proteins and leading to disease. This interference causes a cumulative negative effect, resulting in the buildup of damaged proteins.
Researchers found that stronger, more flavorful onion varieties have higher antioxidant activity and can fight colon cancer cells more effectively. Shallots were also found to be strong cancer-fighters, outperforming milder-tasting onions.
The study confirms that patients benefit from two years of treatment with Macugen for wet AMD, demonstrating a statistically significant 45% treatment benefit. Longer-term use may be beneficial for patients suffering from this chronic disease.
The ENCODE project aims to build a comprehensive 'parts list' of human DNA's sequence-based functional elements, including protein-coding genes and regulatory elements. The initiative will analyze the remaining 99% of the human genome using novel methods and technologies.
Researchers found that bilateral motor performance improvements were seen in patients with Parkinson's disease, regardless of where the stimulation was applied. The study suggests that unilateral deep brain stimulation could be a more effective and lower-risk treatment option for some patients.
Researchers have discovered a way to disable TB protein when it binds to certain molecules, making bacteria more sensitive to treatment by ethionamide. This finding suggests that combining ethionamide with benzylacetone could reduce the dosage of potent antibacterial compounds and improve TB treatment.
Researchers found that beta interferon significantly reduced brain tissue loss and slowed MS progression, with around a third of patients showing improved outcomes. The study's results suggest that beta interferon may be an effective treatment for delaying the progression of multiple sclerosis.
A new computational approach helps researchers understand the relationship between trait differences and variations in the mouse genome, moving closer to understanding human genetic differences. The method also has potential to uncover currently unknown genetic factors contributing to various diseases.
Fossil discovery reveals ancient sea spiders are related to land spiders and scorpions, with the new species Haliestes dasos dating back 35 million years. The preserved specimens provide valuable insights into their unique body form and behavior.
A team of physicists at Georgia Institute of Technology has successfully transferred quantum information from two different groups of atoms onto a single photon. The researchers report using atomic clouds of rubidium atoms as a matter qubit and converting the entanglement into a single photon.
Researchers at Virginia Tech have developed new fiber optic sensors using UV-induced intrinsic Fabry-Perot interferometers, increasing the range and enabling real-time monitoring of large areas. The technology has the potential to create a nationwide network of sensors for infrastructure monitoring with improved multiplexing capability.
A mouse study challenges the idea that a specific gene region is responsible for Down syndrome's characteristic facial features and traits. Researchers found that mice with only two copies of this region still exhibited shorter bones, contradicting previous assumptions.
