Purdue University researchers have engineered plants to produce a non-toxic form of selenium called methylselenocysteine, which has shown promise in reducing cancer risk in animal models. The plants can also accumulate high levels of selenium, potentially providing a natural source for nutritional supplements and environmental cleanup.
A recent study found that 25% of teenage girls experience major depression, highlighting the need for earlier identification and treatment. Decreases in social support and increases in smoking were linked to increased depressive symptoms.
A study found that high levels of CRP in blood are associated with an increased risk of colon cancer, particularly in individuals who do not smoke. Elevated CRP concentrations were also found in people with rectal cancer, but the association was weaker.
Scientists found a significant link between clouds and pollution transport in the Asian-Pacific region. Clouds mask pollutants from spacecraft sensors, leading to underestimated pollution levels.
A study published in The Journal of the American Medical Association found that people with higher CRP levels were more likely to develop colorectal cancers over an 11-year period. Median CRP levels were higher among those who developed colon cancer, and inflammation was linked to increased risk without being mediated by diabetes.
A study found that a computer-aided detection system did not change mammography recall rates or breast cancer detection rates, suggesting it may not be beneficial in academic practices. The results were similar even when focusing on the seven highest-volume radiologists at the center.
A randomized trial found that high doses of folic acid, vitamin B6, and vitamin B12 did not lower the risk of recurrent stroke. However, moderate reduction in blood amino acid levels was associated with a lower risk of stroke, heart disease, and death.
A study found that nursing home residents who wander, exhibit verbally abusive behavior, or have cognitive impairment are more likely to provoke injuries in others. Male residents and those living in Alzheimer's units were also at higher risk. The authors suggest focusing on the behavior of injured persons to prevent incidents.
Researchers discuss the need for additional research and standardization in partial-breast irradiation and accelerated partial-breast irradiation. A new study also finds that preoperative chemoradiation may benefit some patients with rectal cancer, while a diet high in glycemic load is linked to an increased risk of colorectal cancer.
A recent study found that high-dose vitamin therapy had no effect on preventing recurrent strokes and heart attacks. The VISP study involved 3,680 adults who received either a low or high dose of folic acid, B6, and B12 vitamins.
A new study by Cornell University's Liam O'Neill found that distance from a hospital significantly impacts access to medical facilities and outcome for heart attack victims. The study estimates that patients living far from hospitals face a higher risk of death from heart attacks, with approximately 60% expiring before reaching the hos...
A $4 million grant aims to conserve Papua New Guinea's rainforest by discovering medicinal plants. The project seeks compounds active against tuberculosis, HIV, malaria, and cancer, with the goal of providing economic development and biodiversity conservation.
A recent study found a significant link between increased levels of C-reactive protein and colon cancer risk. However, the study's findings do not suggest that C-reactive protein is a definitive marker for colon cancer risk.
Researchers found that brain waves change with each breath, suggesting a new understanding of how sleep apnea affects the brain. The study's novel algorithm detected changes in brain wave activity linked to breathing cycles, promising potential for predicting daytime sleepiness and treatment outcomes.
A recent study found that disabled children with psychosocial problems are less likely to receive mental healthcare, particularly younger and black children. In contrast, joint care coordination between a health professional and family member improved access to outpatient services.
Astronomers have discovered a possible link between a comet impact in the 6th century and the 'Dark Ages.' The comet's debris caused a prolonged cold period, similar to a nuclear winter, resulting in crop failures and widespread starvation. A small comet size was needed to cause such dramatic effects.
Researchers have discovered a new deep-sea jelly, Stellamedusa ventana, which uses its bell and oral arms to capture prey. The jelly's unique feeding strategy is unlike other species, as it prefers larger prey, with some individuals capturing creatures up to 5 cm across.
Researchers detected ClOOCl in the polar stratosphere, triggering ozone destruction through three-step process. The discovery was made during a joint US-European science mission using NASA's ER-2 aircraft.
