Researchers used fMRI to investigate a woman's guilt in a poisoning case. The study found that when she agreed with her accusers' account, her brain activated extensive regions, indicating potential deception.
A new study suggests that treatment can lower the risk of stroke in people with rare lung disease. The research, published in the journal Thorax, found that seemingly healthy patients with pulmonary arteriovenous malformations (pulmonary AVMs) have the same risk of stroke as those who are obviously unwell.
The National Professional Science Master's Association will promote and support professional master's degree programs across the nation, encouraging their expansion and excellence. The organization aims to improve workforce preparation and employment opportunities for graduates of these programs.
A study published in Medical Care found that people infected with HIV continue to die and suffer from AIDS complications due to delayed diagnosis and treatment. Researchers discovered that patients who had received medical care for other illnesses were often not diagnosed with HIV infections earlier, leading to severe complications.
Yi Hua Ma, a Worcester Polytechnic Institute professor, is honored for his research on hydrogen separation using ultra-thin palladium membranes. His work has reduced the cost of generating hydrogen pure enough to power fuel cells.
Researchers found that children of parents who died from these cancers have significantly worse survival rates than those with good parental survival. The risk of death was increased by 75% for breast cancer and 107% for prostate cancer.
Two new studies, led by the University of Michigan Stroke Program, reveal that 69% of stroke victims don't reach the hospital within three hours of symptom onset, resulting in delayed tPA treatment. A middle-school education program shows promising results in improving recognition and response to stroke symptoms.
Researchers at UCLA will use a new super-resolution stimulated emission depletion (STED) microscope to investigate molecular assemblies and biological processes, including chromatin structure and cell signaling. The instrument will also enable the development of new family of STED probes based on semiconductor nanocrystals.
A two-year study found that cooperative activities enhanced students' higher-level skills, such as application of concepts and analysis, compared to traditional lecture methods. Students also developed valuable real-world skills, including communication, conflict resolution, and time management.
Arizona State University has partnered with BP and Science Foundation Arizona to develop a renewable source of biofuel using photosynthetic bacteria. This project aims to produce sustainable high-energy fuel that can be used in conventional engines, reducing our transportation economy's dependency on oil.
The study found that children who received continuous peripheral nerve blockade (CPNB) for pain management after orthopaedic surgery had better pain control and a shorter hospital stay. The catheter system offers continuous relief for up to 100 hours, potentially cheaper than alternative treatments and long hospital stays.
A study published in World Journal of Gastroenterology found that plasma serotonin levels significantly increase in patients with liver cirrhosis, correlating with the degree of liver damage. This discovery provides a potential non-invasive diagnostic method for assessing liver insufficiency.
Scientists question mandatory folic acid fortification in flour, citing risks of unmetabolised folic acid entering the bloodstream and causing problems for people with certain medical conditions. The study suggests that even low doses of folic acid could lead to overconsumption and health issues.
The project aims to create 'smart, self-assembling nano-biomaterials' that can control bacterial adhesion on synthetic surfaces. Successful development of these materials will enable the creation of more resistant biomedical implants.
Research investigates the role of NCAM-180 as a tumor suppressor in colorectal cancer, finding low frequency and lack of prognostic value. The study concludes that routine use of NCAM-180 expression is not feasible due to its rarity.
A new study by Dr. Eric Fombonne found that social skills training groups for autistic adolescents can lead to significant improvements in social and interpersonal skills. The groups, which involve role-playing and peer validation, have been shown to be efficient and effective in reducing problems with irritability and sensitivity.
A 24-week course of interferon-alpha therapy after curative treatment for HCV-associated HCC significantly reduces tumor recurrence rates and improves patient survival compared to those without interferon therapy. Patients who achieved a sustained virological response also exhibit improved liver function and prolonged overall survival.
Italian researchers propose that copper transport protein Ctr1 binds platinum ion from cisplatin, stabilizing the trimeric channel structure and enabling endocytosis. This process allows cisplatin to accumulate in organelles, including the nucleus, where it exerts its antitumor effects.
Mice rely on a highly specialised set of proteins in their urine to recognise different individuals, suggesting this may also be true for other animals. The team found that female mice distinguish between dominant and weaker males by the freshness of male scent-marks.
A novel way to remove iron from ferritin has been discovered by scientists, which could lead to the development of new medications for patients with blood diseases. The study found that a small protein or heptapeptide can bind to ferritin and accelerate its iron removal rate.
A large dose of dexamethasone has been found to improve survival rates and reduce inflammation in rats with severe acute pancreatitis. The treatment also alleviated pancreatic tissue damage and induced apoptosis in acinar cells.
A study by UNC researchers concludes that people over 60 with high blood pressure are less likely to receive lifestyle modification advice from their doctors compared to younger groups. Despite this, most patients remember receiving some type of advice on making healthier choices to lower their blood pressure.
A study by Jason Dyck at the University of Alberta found that a protein responsible for transporting fat into heart cells may be a key to preventing age-related decline in heart function. Genetically modified mice with this protein deficiency showed no accumulated fat in their hearts and outperformed normal aged mice on a treadmill test.
A recent study reveals that coating diamond surfaces with heavier hydrogen isotopes can significantly reduce friction forces. The research, led by Argonne scientist Anirudha Sumant, used single-crystal diamond surfaces coated with layers of atomic or deuterium to investigate the effect on surface vibrations.
Researchers developed a hairpin-shaped molecule that imitates the spatial structure of an important viral protein, preventing the discharge of viral RNA from the cell nucleus. This breakthrough could lead to the development of a new class of HIV treatment drugs.
The study highlights key constraints affecting sweetpotato productivity in developing countries, including control of viruses, improvement of planting material, and development of high-yield cultivars. Small-scale farmers are expected to benefit from emerging technologies based on research, with potential impact within 5-10 years.
Three anesthesiologists and a medical ethicist discuss whether doctors should participate in state-ordered executions, citing technical problems with lethal injection. They argue that doctors can minimize suffering, but others propose replacing anesthesia-related drugs with alternative personnel.
A case report published in the World Journal of Gastroenterology presents a new technique for biliary drainage using endosonography (ES) guidance. The study shows that ESBD is a safe and effective method without pain or restriction, potentially replacing percutaneous transhepatic cholangio-drainage (PTCD).
