A combined approach of photodynamic therapy (PDT) and radiation shows promise in treating mouse tumors, with increased oxygenation improving the effectiveness of both treatments. The study used verteporfin, a light-activated drug that targets tumor tissue, leading to improved outcomes.
Dr. Teitell's discovery of the animal model may uncover genetic mutations that cause certain types of blood cancers. The model could lead to new therapies by identifying cell pathways involved in cancer growth.
A study conducted in California found that infants sleeping on their sides are at an increased risk of SIDS, with a significant increase in risk when they turn onto their stomachs during sleep. The researchers recommend placing babies on their backs every time they go to sleep for consistent safety.
One in five nurses experience multiple types of violence in a single shift period. The Broken Windows theory suggests that tolerating minor acts of aggression among hospital staff creates an environment conducive to more severe violence. Researchers aim to address this issue with a visible response to incidents.
A study on infant rats suggests that high-fat diets and increased production of uncoupling protein 2 (UCP2) may protect the newborn brain from seizure-induced cell injury. The ketogenic high-fat diet is shown to work in human children to prevent or reduce seizures, sparking new research into its potential benefits.
A study led by UT Southwestern Medical Center found that Gleevec, a drug used to treat chronic myelogenous leukemia (CML), does not effectively target CNS leukemia in the brain or spinal fluid. The research revealed that Gleevec poorly penetrates the blood-brain barrier, allowing leukemia cells to avoid eradication.
Research found that composted biosolids can lower lead bioavailability by 20-38% in contaminated garden soil, reducing the danger of poisoning. The study's findings suggest that using composted biosolids as a soil amendment could be a cost-effective alternative to removing and replacing contaminated soils.
Researchers at Virginia Tech have made significant contributions to understanding bear behavior, including the impact of radio-collars on survival rates and the role of dispersal distance in helping bears evade hunters. Their findings also led to the development of a morphometric-based dichotomous key for age identification.
A UCSD biologists' study links human impacts along the coast to size declines of marine snails, particularly among owl limpets and Gilded turban snails. The researchers found that human activity, not environmental change, has led to diminished size in gastropods on the southern California coast.
A recent study found that 95% of skin penetration operators believe guidelines are needed, but only half follow them. Tattoo shop operators were more knowledgeable about infection control than others. Barriers to compliance include client perceptions and busy schedules.
The cloud's mass indicates that Europa faces more severe radiation consequences than previously thought, wielding significant influence on Jupiter's magnetosphere. The discovery uses innovative ENA imaging technique to visualize the three-dimensional structure of planetary space environments.
A new study reveals that ATR kinase plays a crucial role in maintaining genome integrity by regulating cell cycle checkpoints and preventing DNA damage. The study shows that ATR is essential for ensuring cells leave the cell cycle without DNA damage, which can lead to diseases such as cancer.
The National Science Foundation has awarded a three-year grant of approximately $500,000 to the University of Pennsylvania's Mathematics Department to continue its Access Science project. The program provides professional development and hands-on activities for urban teachers to enhance student learning in math and science.
A study found that personalized mailings can significantly increase mammogram use among older women with Medicare, who may need an extra push to get screened due to age-related risk factors. The intervention targeted women over 70 years old without recent mammograms and those with medical conditions preventing screening.
A recent study found that adolescents with high exposure to rap music videos were 3 times more likely to hit a teacher and twice as likely to have multiple sex partners. The researchers also discovered that frequent viewers of rap videos were more likely to acquire an STD, use drugs, and engage in other risky behaviors.
A study of six employers found that employees cost $3,524 a year in average healthcare costs due to physical health conditions. Heart disease was the most expensive condition at $236 per employee, followed by high blood pressure at $160 per employee.
Researchers have identified a gene responsible for the spread of cancer in the body, which could lead to more targeted and less toxic treatment options. The study found that silencing this gene can halt the migration of cancer cells, reducing the risk of metastasis.
