The researchers suggest that these stem cells could be a new treatment for limiting or repairing heart muscle damaged by a heart attack.
Scientists have discovered a new gene, Bnip3L, that helps p53 eliminate cancer cells under low-oxygen conditions. Silencing this gene allows tumors to grow more aggressively in hypoxic environments.
Scientists discovered that humans have only 30,000 genes, far fewer than expected, and that RNA editing plays a crucial role in protein diversity. A-to-I RNA editing has been linked to various diseases, including ALS, epilepsy, and depression, and may shed light on evolutionary processes.
A recent study by Indiana University School of Medicine found that nearly all sexually active adolescent females aged 14-17 were infected with the human papillomavirus. The researchers also discovered that many of these participants had multiple HPV types, which are associated with an increased risk for cervical cancer.
A recent UCSF study found that rates of pregnancy and STIs remained unchanged among young women with increased access to the morning after pill. Despite efforts to make emergency contraception more accessible, only a fraction of women who had unprotected sex used it.
Researchers found that women who received emergency contraception (EC) through pharmacies or advance provision were more likely to use EC than those with clinic access. Despite concerns about increased risk-taking and STIs, the study revealed no significant differences in pregnancy rates or STI acquisition between groups.
Researchers pinpoint MuRF1's role in regulating cardiac cellular molecules involved in abnormal heart enlargement. The protein degrades troponin-1, a critical component of the cardiac contractile machinery, suggesting new therapeutic avenues for treating cardiac hypertrophy.
Researchers found that families with good relationships with their pediatricians received more advice on injury prevention issues, leading to better behavior changes. The study suggests that establishing a trust-based relationship between parents and doctors can lead to improved health outcomes.
A new study found that children's hospitals can do better in preventing hospital-acquired infections, clots in intravenous lines, and bedsores. The analysis suggests ways to refine analytical tools to fit children's care more accurately.
A study found that environmental tobacco smoke exposure is linked to significant declines in reading and math scores, as well as logic and reasoning skills in children. The research suggests that even low levels of exposure can have adverse effects on cognitive abilities, with an estimated 33 million US children at risk.
A study found that childhood obesity decreases quality of life in children, particularly in physical and social functioning. The research also showed a small but significant effect of overweight on children's overall health-related QOL, highlighting the need for early intervention to prevent long-term health risks.
A study found that college students were less willing to hire a woman with two children and judged her as a lesser candidate for promotion compared to a childless woman. Fathers, on the other hand, were held to more lenient standards than both women and childless men.
Researchers have developed a new treatment that significantly reduces morphine use after hysterectomies, leading to improved lung function and more consistent pain relief. The treatment combines two non-opioid drugs, gabapentin and rofecoxib, which work together to alleviate movement-related pain and promote better breathing.
A new study found that blocking VEGFR-3 prevented lymphangiogenesis in a mouse model, potentially inhibiting tumor metastasis. The study suggests that targeting VEGFR-3 may be a viable therapeutic strategy to prevent lymphatic vessel growth and tumor spread.
Falls are a leading cause of death from unintentional injury in the US, with 7% of households reporting a fall requiring medical attention. Homeowners can take steps to prevent falls by installing protective devices such as grab bars, handrails, and safety gates.
Researchers used MRI to study brain activity and found that tens of thousands of discrete brain regions form a network with the same features as other complex networks, such as the Internet. The brain network shares two fundamental properties: small world connectivity and in-homogeneity, allowing for efficient information transmission.
The study aims to understand the complex linkages between environmental change, whale population dynamics, and human societies in Alaska's Arctic ecosystem. Collaborators will investigate climate variability, ice reduction, and its impact on local whaling practices and global commerce.
A team of scientists from Cornell University and international partners will assess the impact of recent tsunamis on Sri Lanka's coastline. The research aims to enhance predictive capabilities and inform future development of tsunami warning systems.
A recent study published in BMC Medicine reveals that environmental factors are a major contributor to higher blood pressure among African Americans, contradicting the long-held assumption of a genetic predisposition. The research found significant variations in hypertension rates across different populations worldwide.
Researchers at McMaster University have used ancient DNA to study the evolution of the Haast's eagle, a giant bird that once ruled New Zealand. The study found that the species is related to one of the world's smallest eagles, with an estimated common ancestor living less than a million years ago.
Researchers found that using a gonad capsule during MDCT scans significantly reduced the radiation dose to the testicles. The study revealed a 87% decrease in radiation exposure when using the gonad capsule compared to those who did not use it.
Researchers from USC found evidence that progesterone signaling influences ovarian cancer risk, particularly two haplotypes (4-D and 4-E) that increase risk by almost 3.5-fold in women who carry them. The study's findings suggest that subtle changes in the progesterone receptor gene may decrease its efficiency, leading to ovarian cancer.
