The Framework Convention on Tobacco Control (FCTC) is a legally binding international treaty aimed at reducing tobacco use, but its adoption in the US is threatened by American exceptionalism. The FCTC covers tobacco taxation, smoking prevention and treatment, illicit trade, advertising, sponsorship and promotion, and product regulation.
Researchers at UCSB discovered a connection between Alzheimer's disease and age-related macular degeneration, both linked to the presence of inflammatory plaques. The study suggests that a toxic protein called amyloid beta may be the underlying culprit, stimulating an inflammation process that contributes to vision loss.
A new study found that spiritual well-being can significantly impact the mental health of terminally ill cancer patients. Patients with high spiritual well-being were less likely to experience strong feelings of hopelessness and suicidal thoughts. The research highlights the importance of addressing spiritual needs in palliative care.
A new multi-center study confirms the effectiveness and safety of infliximab in treating pediatric Crohn's disease, leading to significant short-term medical benefits and a reduced need for steroids. The study shows improved symptoms such as pain, growth rates, and bowel movements, with no adverse reactions at infusion sites.
Researchers found that many patients with SARS developed recurrent fever and worsening lung conditions after initial improvement. The immune system's excessive response to the virus may be responsible for this clinical deterioration in the second week after hospitalization.
Lyman Briggs was a highly influential soil scientist who also pioneered work on high-speed wind tunnels and military technology. His experiments explored water behavior under low pressure, demonstrating the paradoxical fact that water can remain liquid even with minimal pressure.
A Phase II study found that the DVd regimen showed a high response rate of 88%, with 12% achieving complete response. The treatment was well-tolerated, with the most common Grade 3 or 4 toxicity being palmar-plantar erythrodysesthesia. Improved patient education and prevention measures reduced toxicity incidence.
Multidetector CT (MDCT) accurately identified 66 out of 71 total cancers found after additional tests and surgery, including small cancers under 5mm in diameter. MDCT offers a more comfortable and time-efficient alternative to excretory urography for detecting urinary tract abnormalities.
Scientists have identified a novel step in the formation of prions, proteins that cause neurodegenerative diseases such as Creutzfeldt-Jakob disease and chronic wasting disease. By inhibiting this conversion with compounds blocking free sulfhydryl groups, researchers may be able to develop a therapeutic strategy against prion disease.
A new approach suggests using nitrification inhibitors to reduce nitrate leaching to groundwater. Researchers developed management zones based on soil properties and crop yield maps, showing increased yield in wet seasons without affecting grain yield or nitrate leaching in dry seasons.
A Weizmann Institute study found that the Yatir forest is expanding rapidly into the Negev Desert, absorbing more carbon dioxide than expected. This could be due to the increased availability of carbon dioxide, which eases plants' water loss dilemma, allowing forests to grow in areas previously too dry.
Researchers DePaolo and Manga argue that mantle plumes are the primary cause of volcanic activity on Earth. They cite strong evidence from Hawaii and other hotspots, including rapid magma movement and unique chemical signatures. The debate highlights the importance of understanding plume origins for connecting seismology and geochemistry.
Researchers are developing a nanoprobe for early cancer diagnosis using optical coherence tomography, potentially replacing traditional biopsies. The probe aims to pinpoint microscopic changes in tissue structure and blood flow with high-speed, high-resolution imaging.
A new study suggests that CT radiation dose can be reduced by 50% for patients who are small or have low weight, providing acceptable image quality. The researchers used a state-of-the-art CT scanner to assess the quality of liver, spleen, and abdominal wall images in 39 patients aged 65 years and older.
Researchers found that 3D mammography (TOMO) outperforms traditional mammography in detecting breast lesions, including masses and architectural distortions. The technique has the potential to reduce anxiety for patients by providing a more accurate diagnosis upfront.
Researchers have identified 46 new mutations in colon cancer genes that can be targeted by drugs, affecting approximately 30% of colorectal cancers. The study used a forward-looking approach to screen the genes that produce tyrosine kinases, resulting in the discovery of novel mutations that spur colon cancer.
A study found that using mammograms read by specialists reduces call back rates significantly, with an average rate of 8% in the second year compared to 11% in the first year. Specialists are defined as radiologists who have read 3,000 mammograms per year over the last two years.
African-American smokers and non-smokers alike show substantial support for tobacco tax increases to reduce smoking prevalence rates. However, opinions on the fairness of such policies vary, with some arguing they would disproportionately affect low-income smokers.
A reanalysis of previous studies found that new-generation antipsychotics were moderately more efficacious than low-potency conventional drugs but did not significantly reduce neurological side-effects. Clozapine was the only new-generation drug associated with fewer side-effects and higher efficacy.
Researchers report successful treatment of 50 out of 51 renal tumors using radiofrequency ablation. The therapy is particularly effective for tumors on the outer surface of the kidney due to surrounding fat insulation.
Researchers discovered mutations in 14 tyrosine kinase genes, which play key roles in controlling cell growth and differentiation. These findings open the door to individualized treatment approaches for colorectal cancer, allowing for personalized therapeutics tailored to each patient's tumor DNA.
Scientists report evidence of catch bonds regulating white blood cell activity, offering potential targets for anti-inflammatory compounds and cancer metastasis control. Researchers discovered prolonged bond lifetimes with increasing force, contrary to initial theories.
A New Mexico State University scientist's study reveals that the cost of maintaining the upstream habitat for the endangered silvery minnow results in a net gain of $68,000 per year for New Mexico agriculture. However, central New Mexico agricultural users and Albuquerque residents would lose $68,000 annually, while southern New Mexico...
Schepens Eye Research Institute scientists have discovered a new drug that can trap abnormal growth factors in the cornea, potentially improving corneal transplants. Additionally, a gene therapy approach has shown promise in preventing and treating autoimmune diseases like uveitis by inducing a protein called a-MSH.
Radiofrequency ablation has shown promising results in treating advanced lung cancer, with significant pain reduction and improved survival rates. The procedure involves using extreme heat to destroy or slow the growth of tumors, and can be used as an alternative to surgery, chemotherapy, and radiation therapy.
