Researchers found that long-term albuterol use can lead to accumulation of the (S)-isomer, which reduces anti-inflammatory effects and worsens asthma symptoms. The study suggests that current combination therapies may not be realizing their full potential due to isomer interactions.
A study of 1,991 Iraqi men and women found that human rights abuses were common, with 47% reporting torture, killings, or other forms of abuse. The Baath party regime was identified as the primary perpetrator of these abuses, with 95% attributed to Baath party-affiliated groups.
Researchers found cognitive behavior therapy significantly reduced hypochondriacal symptoms, beliefs, and attitudes, as well as health-related anxiety. CBT also improved social role functioning and daily living activities in patients with hypochondria.
Engineers at Ohio State University used compressed carbon dioxide to embed protein molecules in plastic, creating a process for developing implantable drugs. The technology could be used to release medicines into the body, improving medical treatment and reducing environmental impact.
Webster Cavenee receives $250,000 grant from National Foundation For Cancer Research to study cancer tumors. His research focuses on defining genetic lesions in human cancer and developing therapeutic approaches.
Chronic sinusitis is an immune disorder caused by fungi in the mucus lining of the sinuses. Antifungal medicine has been shown to be effective in reducing inflammation and nasal swelling. The study suggests a new potential treatment approach for this common disease.
Researchers observed electronlike excitations at temperatures above the transition temperature in cobaltate materials, suggesting a novel mechanism for high-temperature superconductivity. This discovery opens up new avenues for understanding the phenomenon of high-temperature superconductivity.
A report by the International Zinc Nutrition Consultative Group finds that zinc deficiency affects millions worldwide, particularly in developing countries. It highlights methods for assessing population zinc status and potential strategies for controlling nutritional deficiencies through supplements and public education.
The AACR International Scholars in Breast Cancer Research program aims to improve cancer research and clinical care worldwide. Principal Investigators will mentor talented scientists from under-resourced countries, enhancing their skills and knowledge for successful breast cancer research.
The experiment detected three events consistent with the rare K meson decay, which occurs once in every 7 billion decays. The result suggests a possible departure from the Standard Model, but further analysis is needed to confirm or rule out the discrepancy.
A study led by Baylor College of Medicine and the University of Rochester Medical Center is testing a vaccine against H9 bird flu, which infected several people in Hong Kong in 1999. The goal is to prepare for potential transmission of the virus from person to person.
Researchers have extended atmospheric record of methyl bromide over 300 years by analyzing air bubbles in an ice core. The study shows that global atmospheric methyl bromide levels increased significantly during the industrial era.
The U-M group uses lab-made dendrimers as the backbone of their delivery system, which can attach targeting agents to recognize cancer cells and deliver lethal doses while leaving normal cells unharmed. Early results show that nanoparticle drugs effectively treat cancer with fewer side effects than conventional chemotherapy.
Researchers at Duke University Medical Center have demonstrated the feasibility of brain-machine interfaces (BMIs) in humans, using arrays of electrodes to record brain signals and control external devices. The study showed that patients with Parkinson's disease and tremor disorders could use BMIs to play a hand-controlled video game.
Researchers at the University of Toronto have created a new gel-like substance that guides neural cells through channels, providing a greater surface area for neural stimuli transmission. This breakthrough could lead to stronger signals in regenerated nerves, paving the way for regenerative medicine applications.
A study published in Obesity Research found that customers who were served larger portions of high-calorie foods consumed significantly more calories, often without noticing. The study's findings suggest that portion size can have a significant impact on food consumption and weight management.
A recent study from Ohio State University found that listening to music during exercise improves verbal fluency test scores in cardiac rehabilitation patients. The study also revealed that participants reported feeling better emotionally and mentally after working out regardless of whether they listened to music.
A study found that nearly half of rural North Carolina adults use home remedies for various health conditions. The most common remedies used were honey-lemon-vinegar-whiskey for respiratory issues, herbs for cardiovascular conditions, and teas for general well-being.
The Oregon Stem Cell Center aims to develop therapies using adult stem cells for human diseases through a rapid approach from basic research to animal trials and human studies. The center's focus will be on the liver and pancreas, building on OHSU's existing expertise in cell therapy.
A study of premenopausal women with abnormal uterine bleeding found that hysterectomy improved health-related quality of life within six months compared to expanded medical treatment. Another study in Finland compared the LNG-IUS to hysterectomy for menorrhagia, finding similar outcomes and lower costs for the intrauterine system.
A study published in Agronomy Journal suggests that producers can reduce seeding rates for Roundup Ready soybeans without affecting yield, especially in northern Wisconsin. This approach could be economically viable for farmers in certain regions, but current recommendations may still be suitable.
Professor Sandra C. Greer was recognized for her dedication to encouraging women in chemistry, with over half of her Ph.D. students being female. She has supervised 14 Ph.D. dissertations and chaired the University of Maryland Department of Chemistry and Biochemistry.
Harvard chemist Harold Corey has made thousands of complex chemical structures, leading to medicines like Celebrex, Singulair, and Xalatan with sales over $10 billion annually. His approach of mentally dissecting molecules into simple building blocks is now a standard in academic and commercial research.
Researchers found that apoE4 produced by neurons is susceptible to fragmentation, leading to increased tau phosphorylation and damaging brain cells. The study suggests targeting a neuron-specific enzyme to prevent Alzheimer's disease progression.
The Virginia Tech trio of Tom Ward, James McGrath, and Garth Wilkes has been awarded the Paul J. Flory Polymer Education Award by the American Chemical Society Division of Polymer Chemistry for their long-term efforts in educating students in polymer science and engineering. The award recognizes the trio's creation of an interdisciplin...
A new species of deep-sea predatory fish, dubbed Eustomias jimcraddocki, has been discovered by Dr. Tracey Sutton at the Harbor Branch Oceanographic Institution. The species exhibits unique bioluminescent features and varying barbel patterns, challenging previous assumptions about its functionality.
Scientists have identified amino acid sequences that allow prions to aggregate and replicate, leading to the creation of an artificial yeast prion. This breakthrough sheds light on the mechanisms behind diseases like mad cow disease and Alzheimer's, potentially paving the way for new treatments.
