Researchers at Western Australian Institute for Medical Research (WAIMR) have cured mice with a congenital myopathy disorder that causes babies to be born without normal muscle function. They achieved this by replacing missing skeletal muscle actin with heart actin, allowing the mice to live normally into old age.
A new tool helps decision-makers determine when and how to use managed relocation, a strategy considered too radical for serious consideration in the past. The approach involves moving species into more accommodating habitats where they are not currently found.
A study by Johns Hopkins Medicine found that vestibular dysfunction increases the risk of falls among middle-aged and older Americans. The survey revealed that people with diabetes are more likely to suffer from balance problems, and that balance testing needs to be part of basic primary care.
Researchers at La Jolla Institute have identified a cellular defect that increases the risk of severe reactions to the smallpox vaccine in people with eczema. Boosting Natural Killer cell activity may help prevent such reactions.
Researchers analyzed 22 trials of web- and computer-based smoking cessation programs, finding a significant improvement in success rates compared to quitting alone. The studies involved nearly 30,000 participants and showed that these programs can be an effective, cost-effective way to help smokers overcome tobacco dependence.
People taking cholesterol-lowering statins after a stroke are less likely to have another stroke and die within 10 years. Statin use reduces recurrent stroke risk by 35% and mortality risk by 57%. Anti-inflammatory and antioxidative effects of statins may contribute to this benefit.
Researchers found that rooks can use tools to solve problems and adapt them for better performance. They also demonstrated sequential tool use and creative modifications.
A study by University of Florida researchers suggests that the nervous system may be the primary cause of severe breathing problems in children with Pompe disease, a rare genetic disorder. The discovery shifts responsibility from muscle weakness to signaling between the spinal cord and the diaphragm.
A study published in Archives of Internal Medicine found that retail clinics tend to be located in areas with higher median incomes and home ownership rates. In contrast, counties without these clinics have higher uninsured rates and lower socioeconomic status.
Researchers found health-related activities in Second Life, including disease-specific support groups, virtual simulations, and medical research. These activities have significant implications for patients' experiences, offering a safe environment to seek information and share health experiences.
A study found that faculty physicians who spent more time on their most meaningful activities had lower rates of burnout. The authors suggest that career fit can be optimized by providing additional time for physicians to pursue their passions.
Researchers Finarelli and Flynn challenge the Social Brain Hypothesis, finding that increased brain size is not routinely associated with sociality in carnivores. They document at least six separate changes in brain sizes across different lineages of mammals.
A meta-analysis of 22 randomized controlled trials found that web- and computer-based smoking cessation programs increased abstinence rates by 1.5 times compared to control groups. After six to 10 months, intervention groups had an 11.7% quit rate, while control groups had a 7% rate.
Researchers found that a heart muscle protein, ACTC, can compensate for a lack of skeletal muscle protein, ACTA1, in mice with myopathy. Mice with this compensation survived more than three months and showed improved endurance, locomotor performance, and muscle strength.
Michigan State University researchers identify two new genes and two new enzymes in tomato plants that produce monoterpenes, a compound responsible for the plant's distinctive smell. The discovery challenges traditional understanding of how plants make monoterpenes, opening up new avenues for protecting plants from pests.
Researchers have identified a genetic link between periodontitis and coronary heart disease (CHD), with a shared genetic variant located on chromosome 9. The study found that the genetic variation associated with both diseases is identical, indicating a strong genetic basis for the connection.
Research suggests that lymph nodes are not necessary for marshalling T-cells to respond to skin breaches, with the liver playing a key role instead. This discovery implies a novel function for the liver and offers insights into the evolution of immune systems in mammals.
A new study found that retail clinics are more likely to be located in higher-income areas, making it difficult for poor and underserved communities to access medical care. The clinics' location may be an adjunct to existing traditional medical care rather than addressing unmet needs.
A study published in the Canadian Medical Association Journal found that primary care physicians who adopted a new capitation model for payment had fewer sick patients and less after-hours billing. However, they also had more patients visiting emergency departments and fewer new patients compared to those who opted for an enhanced fee-...
A study by ICES found that doctors in Ontario's Family Health Network (FHN) model had fewer visits with chronically ill patients and provided less after-hours care. The FHN model pays doctors based on a capitation payment system, whereas the fee-for-service model paid per visit.
Women experience cognitive decline during the menopause transition, with verbal memory and processing speed affected. However, these declines are temporary and resolve once women enter postmenopause, suggesting that estrogen or progesterone may have a beneficial impact on brain function before menopause.
A study published in Archives of Internal Medicine found that only half of patients diagnosed with metastatic lung cancer discuss hospice options with their physicians. The study also revealed disparities in hospice discussions among different racial and marital groups, highlighting the need for improved end-of-life care conversations.
The study found that 35% of U.S. adults aged 40 and older have vestibular dysfunction, which can increase the risk of falling. Individuals with vestibular dysfunction are more likely to report dizziness and a history of falls.
Researchers call for clear communications, external analysis, and a review focusing on quality care to address large-scale medical errors. The authors argue that national guidelines would ensure more timely disclosure and improve patient safety.
A genome-wide association study identified 20 single nucleotide polymorphisms related to an earlier menopause, which could affect fertility in women. The study suggests that understanding these genetic variants may help improve fertility treatment for women with infertility issues.
Researchers at McGill University found that statin therapy can inhibit myelin repair in Multiple Sclerosis patients. The study suggests a negative impact of long-term statin therapy on remyelination and oligodendrocyte number.
A study using genetically modified mice found a link between low levels of inositol and neural tube defects, such as spina bifida. The research suggests that increasing inositol doses may help prevent these birth defects.
A population genetics study found that parasite-driven selection has left a footprint on human DNA, particularly in immune genes. This variation correlates with parasite diversity and may contribute to the development of inflammatory bowel diseases.
A brain-imaging study found that cocaine users show reduced activity in areas involved in monitoring behavior and regulating emotions, suggesting these impairments may underlie addictive vulnerability. Improving these functions could help addicted individuals resist drugs.
The Climate Disclosure Standards Board has proposed a global framework to enhance corporate transparency by including climate change data in companies' annual reports. The framework clarifies which climate change data should be reported and provides guidelines for streamlined disclosure procedures.
