Scientists created a new mouse strain with a genetic deletion that affects stress hormones and behavior. The mice exhibit anxiety-like behavior consistently, not just in response to external stimuli, offering insights into the role of CRH-binding protein in depression and anxiety disorders.
A team of researchers has identified several chemical compounds that can prevent HIV from fusing with human cells, a crucial step in the viral infection process. By targeting the gp41 protein, these compounds may provide a new avenue for treating HIV and potentially other viruses.
Researchers at Duke University discovered that cancer gene c-Abl triggers the internal framework of cells, building nerve cells and aiding movement. Altering levels of growth factors and Src protein revealed c-Abl's normal function.
Researchers at the UK College of Medicine are developing a technology to deliver drugs directly into brain tissue to treat Parkinson's disease. The team plans to use a modified Medtronic pump to deliver GDNF, a protein that has shown promise in protecting dopaminergic neurons in preclinical studies.
Researchers have successfully engineered cardiac tissue, a crucial step towards repairing damaged heart tissue and testing new drugs. The team characterized the tissues' structural and electrical properties, identifying key parameters for growth and development.
A pan-European study found that type 2 diabetes in Europe is a significant healthcare burden, with total costs exceeding €29 billion and average individual costs more than double those of the general population. Preventing long-term complications through urgent action is crucial to reducing these costs.
New data confirm Relenza's effectiveness in targeting viral replication and reducing complications in patients with influenza B. High concentrations of the drug in the lungs also reduce the risk of resistance development.
Research highlights potential causes of autoimmune diseases, including prenatal exposure to environmental chemicals and certain dietary factors. Studies also explore links between ultraviolet radiation, stress, and exposure to heavy metals.
Researchers found that rosiglitazone treatment improved glycaemic control and reduced risk factors for coronary heart disease in patients with type 2 diabetes. The medication also showed promise in reducing protein excretion and triglycerides, while improving lipid profiles.
A study of 46 Internet sites selling prescription drugs found that only five revealed their locations, while nine sites sold medications without a physician's prescription. The researchers also found that online doctor consultations cost more than in-person visits, and some popular drugs were sold at higher prices online.
The National Institute on Drug Abuse has launched a $55 million clinical trials network to rapidly test promising treatments for drug addiction. The network, which will consist of 20-30 regional research centers, aims to bridge the gap between research and practice by partnering with community-based treatment programs.
Rosiglitazone reduces insulin resistance by 33% and improves pancreatic function in individuals with type 2 diabetes. The treatment also reduces insulin levels in the blood, potentially alleviating the need for regular insulin injections.
A study has identified perchlorate in fertilizers, a chemical compound suspected of adverse health effects. The findings suggest that fertilizers could be a source for perchlorate accumulation in the food chain, posing risks to human health and ecosystems.
Researchers at MGH discovered TGF-beta-1 inhibits blood vessel growth associated with metastatic gallbladder cancer. The study's results may lead to anti-angiogenesis agents for cancer treatment.
A groundbreaking study reveals differences in the human brain's neural architecture compared to apes and monkeys. Researchers found a uniquely human feature in the magnocellular pathway of the primary visual cortex, which may help understand diseases like dyslexia.
Studies suggest that involving individuals with diabetes in their care can improve quality of life and reduce complications. The results highlight the importance of patient education and empowering patients to make informed treatment choices.
