Researchers at Washington University in St. Louis have successfully made boron nanowhiskers, the world's first crystalline nanowires, exhibiting semiconducting behavior and potential as key materials in nanoelectronics. The discovery could lead to the development of more reliable conductors, solving limitations faced by carbon nanotubes.
Regular cranberry juice consumption could reduce UTI development and need for antibiotics, potentially slowing antibiotic resistance. Cranberry's anti-adhesion properties prevent bacteria from sticking to the urinary tract.
Researchers found that increasing UVB levels in wetlands are associated with an increased frequency of frog malformations. The study suggests that UV radiation may be a significant contributor to the decline of amphibian populations, particularly in areas where ozone depletion and climate change reduce natural UV protection.
A new study conducted in New Zealand found no increased risk of prostate cancer among men who had undergone vasectomy. The study, which interviewed over 2,200 men, suggests that vasectomy does not pose a biological risk for prostate cancer.
A study by Troost found Botox to be an effective preventive therapy for headache treatment, with 92% of patients experiencing improvement after four treatments. This alternative approach can reduce medication use and side effects, offering a promising solution for debilitating headaches.
A new analysis suggests that early statin use after a heart attack is only effective in patients with high cholesterol levels above the recommended guidelines. The study found no difference in mortality rates between those who received early statins and those who did not.
A study of female radiologic technologists found that prolonged exposure to low dose radiation is associated with a higher risk of breast cancer mortality. Women who started working as radiologic technologists before 1940 were nearly three times more likely to die from breast cancer than those who began working in 1960 or later.
A study found that the GSTP1 polymorphism was associated with increased survival in patients with advanced colorectal cancer who received platinum-based chemotherapy. Meanwhile, research on human herpesvirus-8 suggested that the K1 gene may play a role in malignant transformation.
University of Pittsburgh researchers found combined PET/CT scans to be a valuable tool for staging and re-staging patients with difficult-to-track cancers. The technology identified additional cancerous lesions in 80% of ovarian carcinoma patients and 45% of cervical carcinoma patients, leading to changes in treatment plans.
Scientists have identified brain chemicals that can stimulate nerve regeneration after spinal cord injury, providing a potential new target for intervention. By understanding how these chemicals interact with inhibitors, researchers hope to develop treatments to repair damaged nerve cells and improve outcomes for patients.
The study found that between 1950 and 1960, male cancer mortality was nearly 50% greater in high socioeconomic areas compared to low areas. By 1998, this gap had narrowed and even reversed, with the lowest socioeconomic groups experiencing higher mortality rates.
A study found that genetic mutation penetrance for melanoma varies by geographic location, with higher risks in countries like the US and Australia. Researchers suggest environmental factors contribute to this variation, contradicting previous assumptions about gene mutations and their impact on disease expression.
Researchers found over 200 groups of adjacent and similarly expressed genes in Drosophila melanogaster, accounting for approximately 20% of the genome. The 'sloppy' regulation may reflect chromatin's packaging and influence gene expression more by accident than design.
Researchers at Purdue University and the USDA have developed tomatoes with significantly higher levels of lycopene, a key cancer-fighting antioxidant. The genetically modified tomatoes contain up to 3.5 times more lycopene than conventional varieties, which may help reduce the risk of certain cancers and heart disease.
Recent studies have shown that combining Xenical with a mildly reduced calorie diet can improve glycaemic control, body weight, and waist circumference in overweight or obese patients with type 2 diabetes. The medication has been found to reduce HbA1c levels by as much as 46% in patients with poor glycaemic control.
A new computational model developed at Purdue University accurately predicts the performance of thermal-barrier coatings, allowing designers to predict the properties of various mixtures. The model has been shown to be over 90% accurate and promises to save time and money by ruling out ineffective mixtures.
Researchers found Xenical significantly improved HbA1c and fasting plasma glucose levels in patients with type 2 diabetes. Additionally, treatment with Xenical showed post-prandial glucose benefits and cost-effectiveness as an adjunctive therapy to oral anti-diabetic medications.
LY333531 improves nerve function and sensory symptoms, including tingling and numbness, of diabetic neuropathy. The treatment is being studied for multiple diabetic microvascular complications, including diabetic retinopathy and nephropathy.
A NASA study found that urban heat islands create more summer rain over and downwind of major cities worldwide. The increased heat promotes rising air and alters weather patterns, leading to higher rainfall rates in urban areas.
Researchers found that certain fungi can supply calcium to trees in acidic soils, reducing the loss of essential nutrients. However, not all tree species have beneficial fungal associations, and other factors like soil acidity can still hinder plant growth.
Researchers at Ohio University found that a behavioral therapy program reduced migraine frequency and severity in teens by 80%, with no medication required. The study suggests an alternative approach to treating migraines in children and teens.
A new set of patient interview questions has been developed to improve understanding of Hmong culture and traditions. The study found that many patients use both shamans and physicians for their health care, highlighting the need for a more holistic approach to patient care.
A computer model reveals that genetically modified organisms (GMOs) can lead to the extinction of natural populations in as few as 20 generations. The research also identifies an 'invasion risk' where introduced genes spread through the population without reducing overall size.
A study by Dartmouth/VA researchers found that major US news media favored routine use of screening mammography and urged caution about tamoxifen, with greater emphasis on the negative aspects of the latter. The coverage of these issues highlights the need for balanced media reporting to focus on science rather than emotions or politics.
