Research reveals a strong link between stroke damage to brain region putamen and motor neglect, a condition causing slow movement on the left side. Treatment targeting dopamine-like compounds may ease this disability in patients with Parkinson's disease.
A study of 372 men with prostate cancer found that 49% had osteoporosis, with those receiving hormone therapy and having undergone radical prostatectomy being at highest risk. The authors suggest that daily calcium intake could be used as a prognostic factor for osteoporosis in these patients.
Researchers at the University of Oregon have discovered the structural basis for photoswitching in fluorescent proteins, allowing for control over light emission. The study revealed that inserting a single oxygen atom can delay the switch-on time from five minutes to 65 hours, enabling more precise studies within cells.
Researchers provide new insights into how a key protein used to fight viruses works, raising hopes for improved treatments against viral infection. Additionally, heart stem cells are shown to be unaffected by acute heart failure, making them available for cardiac recovery. A chemical called thioredoxin also helps prevent loss of neuron...
A study suggests that stem cell transplantation can induce extended insulin independence in patients with type 1 diabetes. The therapy involved high-dose immunosuppression followed by autologous nonmyeloablative hematopoietic stem cell transplantation, resulting in 93% of patients achieving periods of insulin independence. The treatmen...
A new P2P system, Similarity-Enhanced Transfer (SET), can significantly speed up music and movie downloads by leveraging similarities between files. By identifying relevant chunks of files, SET greatly increases the number of potential sources for downloads.
Researchers at Oklahoma Medical Research Foundation discovered that ApoE4 attaches to a receptor on brain cells, leading to protein fragment formation and cell death. This finding may lead to new pathways for developing Alzheimer's therapeutics.
ConocoPhillips has established a $22.5 million eight-year research program at Iowa State University focused on developing biorenewable fuels technologies, including ethanol and biodiesel from organic materials. The program aims to promote energy diversification and reduce greenhouse gas emissions.
Researchers report on patients who suffered toxic side effects from taking excessive doses of niacin, a common vitamin used to pass urine drug tests. The study warns against this practice due to the risks of liver toxicity, hypoglycemia, and other serious health issues.
A recent study by Dr. Jesús Gómez-Zurita and collaborators found that phytophagous leaf beetles (Chrysomelidae) radiated independently of their host plants, with origins dating back to the late Cretaceous period. This challenges the long-held coevolution hypothesis, suggesting a more complex evolutionary process.
