A new study found that only 2% of patients who experienced an allergic-like event after the first penicillin prescription had another reaction, despite previous estimates suggesting a 60% rate. The researchers suggest that some patients labeled as penicillin-allergic can safely receive the antibiotic in emergency situations.
Scientists have found that magnetic field reversal events occur within certain time-frames, regardless of polarity, with an average duration of 7,000 years. The variation in duration is influenced by latitude, taking half as long at low-latitude sites compared to mid- and high-latitude sites.
A study published in Neuron found that a lack of RIM1 alpha protein leads to profound deficits in learning and memory, impacting mice with symptoms similar to schizophrenia. The discovery offers insights into the molecular events underlying learning and memory processes.
Michelle Edwards, a UH College of Pharmacy student, took first place in the Patient Counseling Competition at the American Pharmacists Association (APhA) national convention. She demonstrated exceptional ability to communicate under pressure and will receive $1000 and an all-expense-paid trip to judge the 2005 competition.
A study found 16 non-native species of fish in ocean waters off the southeast coast of Florida, released from home aquariums. Aquarium owners are often unaware of the potential pitfalls of releasing pets into the wild, and education programs can help curtail exotic species introductions.
Researchers analyzed data from 96,545 galaxies to track star formation history. They found that massive galaxies formed stars earlier than smaller ones, and star formation has decreased since then, contributing to the gradual dimming of the universe.
Research suggests that sloths expel larger particles more efficiently than expected, potentially due to unique digestive adaptations. This study challenges the conventional wisdom on sloth behavior and highlights the importance of considering the interplay between resting posture, digestive anatomy, and ingesta characteristics.
A recent analysis of 11,633 species published in Nature found that more than 300 critically endangered species are completely unprotected. The study emphasizes the need for a major shift in conservation strategies to prevent large-scale species extinctions over the next few decades.
Rett Syndrome researchers successfully introduced the 'Rett protein' into post-mitotic neurons, reversing symptoms in mice. This breakthrough could pave the way for new treatments and potentially even cures for Rett Syndrome, a devastating neurological disorder primarily affecting girls.
The NSF-funded Collaborative Undergraduate Experiences program pairs US students with international mentors at top institutions in Japan, Taiwan, and Australia. Students work on projects related to cyberinfrastructure, exploring its potential impact on science and global collaboration.
AstraZeneca has submitted a regulatory application to the European Union for the use of Atacand in treating heart failure. The CHARM study programme showed that Atacand reduces both cardiovascular deaths and hospital admissions across a broad spectrum of patients with chronic heart failure.
Researchers at Stanford University challenge the existence of a single supercolony of Argentine ants spanning California. Instead, they propose that multiple genetically distinct colonies have colonized the state over the past century.
Time-reversal acoustics (TRA) systems hold promise for precise medical imaging, diagnostic techniques, and incision-free surgical methods. TRA's ability to focus sound waves accurately in dense environments makes it an attractive solution for imaging the human body or targeting tumors non-surgically.
A 12-month quality of life study with Parkinson's patients shows significant improvement in movement and quality of life after receiving a transplant or sham surgery, regardless of actual treatment. The study suggests that the placebo effect plays a crucial role in this disease.
Australian researchers introduce a simple method to collect, archive and process DNA from wildlife samples using FTA databasing paper, which preserves DNA integrity despite temperature fluctuations. This technique enables the transport of large reference collections over long distances, enabling extensive wildlife studies.
Genetic studies of leukemia patients have led to the identification of specific gene mutations linked to treatment responses and drug resistance. This information is guiding the development of new drugs targeting specific cell molecules, reducing toxic side effects.
Researchers at the University of Illinois developed an activity called 'See it, Do it, Teach it' to help people understand nutrition labels and increase their calcium intake. The eight-week study showed that participants significantly increased their calcium consumption, getting closer to daily requirements.
A new study found that children who stayed in the ICU for more than 48 hours after cardiac surgery were at a higher risk of developing post-traumatic stress disorder (PTSD). Five out of 43 children met diagnostic criteria for PTSD, with symptoms including disorganized behavior, nightmares, and concentration problems.
