A new study reveals that a key signaling mechanism can turn healthy cells into tumors and lead to colon cancer. The researchers identified the role of beta-catenin in this process and found that it is involved in essentially all cases of colon cancer.
Researchers found that bulimics exhibit a range of physiological and psychological problems, including abnormal blood pressure, poor response to stress, and low self-esteem. The study also revealed that bulimics are more likely to experience cardiovascular problems and major depression.
US unemployment remains below 6%, with record employment rates globally. North Carolina's economy is robust, with a seasonally adjusted annual rate of $165.65 billion in the third quarter of 1996, exceeding national growth. Despite a concerning education system, Smith recommends policy changes to enhance economic prospects.
Researchers at the University of North Carolina at Chapel Hill are investigating soybean component genistein's potential to prevent and treat cancer. The study aims to determine safe doses and treatment efficacy in humans, building on existing evidence from Japanese diets rich in soybeans.
A UNC-CH report evaluates the effectiveness of family planning programs in developing countries, identifying key components linked to success. The research emphasizes the importance of evaluation in allocating resources for maximum impact.
A new study published in the Annals of Internal Medicine suggests that intensive education for doctors and special programs within hospitals are more effective in changing the kind of care dying people receive than advance care directives. The study found that sophisticated educational techniques can motivate doctors to change their be...
A study led by Dr. Steven Wing found that lung cancer and leukemia rates were significantly higher downwind of the Three Mile Island reactor than upwind, consistent with high radiation exposures. The researchers conclude that radiation from the accident increased cancer in areas affected by radioactive plumes.
Researchers found a three-drug combination of indinavir, zidovudine, and lamivudine significantly reduces AIDS symptoms and prolongs patient survival compared to two-drug combinations. The study enrolled 1,156 participants and showed a 45% reduction in disease progression events.
Researchers have identified an inactive gene that contributes to cancer development when it fails to work in harmony with the tumor-suppressing p53 gene. The findings suggest that the bax gene can act as a tumor suppresser, and its dysfunction may lead to increased cancer cell death and tumor growth.
The Ocutech VES AutoFocus Telescope is the world's first self-focusing telescopic glasses for the visually impaired, developed by Dr. Henry Greene and his team. The device can help several million people in the US alone, providing improved vision and recognition of faces and objects.
Researchers at UNC-CH launch first major investigation of colon cancer in both black and white populations, exploring environmental factors and dietary influences. The four-year study aims to identify key risk factors and promote a better understanding of the disease among African Americans.
Scientists found that 65% of alcoholics preferred sweetest solution compared to 16% of non-alcoholics, linking liking sweets to increased propensity for alcohol consumption. Researchers hope to develop a predictive test using the sweet test to screen youngsters at risk of developing alcoholism.
Researchers find massive methane deposits in Blake Ridge area, equivalent to 35 billion tons, and estimate 7% of global carbon stored. The discovery suggests a significant role in past climate change and potential for future energy source.
Research by UNC-CH history professor Dr. Richard Kohn helped lead President Bill Clinton's awarding of the Congressional Medal of Honor to black WWII veterans. The research uncovered instances of racism and black heroism, leading to the re-evaluation of over 40 black soldiers' nominations for the top military honor.
Researchers found state-level media more likely to affiliate with the Democratic party, particularly in the South. However, a study published by Dr. Thad Beyle and colleagues found that partisan bias does not appear to affect coverage of governors.
A new study by the University of North Carolina at Chapel Hill reveals that Evangelicals are the most active Christian group in donating money to candidates and demonstrating for their beliefs. They feel threatened by current trends in US culture and strongly identify with Republican values.
Researchers have found a new technique to reduce organic and halogenated solvents used in industries, replacing them with environmentally benign carbon dioxide. This breakthrough could decrease waste by up to 100-fold and has implications for society.
A new company, Xanthon Inc., will develop and market a genetic detection diagnostic kit using advanced electrochemistry. The kit aims to improve the efficiency, speed, and accuracy of cancer and infectious disease diagnoses.
A new study finds that obese Blacks are more likely to experience physical disabilities due to their weight, with a 30% greater risk than Whites. Researchers at the University of North Carolina at Chapel Hill examined functional differences between Blacks and Whites in rural Johnston County.
A new study reveals that media reports of vaccine injuries can cause fear, lead to costly litigation, and prevent infants from being immunized. The authors urge journalists to report on rare adverse events without distorting the facts, highlighting the importance of accurate information in protecting public health.
Dr. Patricia Gensel and her husband discover ancient arthropods in Canada, including scorpions and millipedes that lived on land over 200 million years before dinosaurs appeared. The fossils provide conclusive proof of large land-dwelling arthropods existing early in the Paleozoic era.
A global study of children's weights and heights found a significant association between stunting and overweight in kids from diverse countries. The research suggests that critical periods for weight gain include infancy, childhood, and adolescence, emphasizing the importance of healthy feeding practices.
A new University of North Carolina at Chapel Hill study reveals that women with non-ischemic heart failure have a significantly higher survival rate than men, even after accounting for differences in age and other factors. In contrast, men with ischemic heart failure were more likely to die prematurely.
A recent study published in The Lancet found that a specific HIV vaccine, MNrgp120, did not stop the virus from reproducing or slow immune system destruction. Researchers evaluated 568 volunteers infected with HIV and found no significant differences in CD4 counts between those who received the vaccine and those who received a placebo.
Researchers at UNC-CH and Penn State University have identified a gene called KiSS-1 that controls the spread of malignant melanoma in laboratory mice. This finding may help doctors distinguish between tumors that will colonize other organs and those that will not.
Children drank ale at breakfast, lunch and dinner, with average daily consumption being a gallon for adults and less among children. Women brewed most of the ale consumed during the 14th and 15th centuries, challenging common assumptions about women's roles in medieval society.
Scientists have discovered that Archaeopteryx, the famous link between birds and reptiles, did not give rise to modern birds. Instead, they appear to have descended from a different, unknown ancestor with many characteristics of modern birds. This discovery challenges the classic view of bird evolution.
