Researchers found that breast cancers behave differently before and after age 70. Women aged under 70 are less likely to have aggressive tumors spreading to lymph nodes as they age, but the opposite occurs for women over 70. Decreased immune defense mechanisms may play a role in this change.
Researchers at Fox Chase Cancer Center have identified a molecule, IPA-3, that can shut down PAK1, an enzyme involved in pathways leading to breast cancer. The molecule achieves high selectivity for PAK1 by binding to its auto-regulatory arm, preventing the enzyme from becoming active.
Researchers confirm structure of Greenland Ice Sheet plumbing and find that summertime melt indeed contributes to the speed up of ice loss. However, they also conclude that summertime melt is not as critical a factor as other causes of ice loss.
A study of 1,394 women found that those with low vitamin D levels had a significantly increased breast cancer risk. Carriers of certain polymorphisms in the vitamin D receptor gene also showed an increased risk of developing breast tumors.
A study found that acupuncture reduces hot flushes in breast cancer patients taking tamoxifen by 50%, with a sustained effect after treatment cessation. Acupuncture also improves overall well-being and has the advantage of being cheap and side-effect-free compared to other treatments.
Researchers at UC San Diego have created the first 3D image of an antibody gene, shedding light on the human genome's three-dimensional structure. The study uses geometry to resolve the structure of a genetic locus, revealing 'flower-like' structures connected by linkers that generate diverse antibodies.
The US Department of Homeland Security has developed a wearable hood for emergency escape with 15-minute chemical protection. The EH-15 mask provides protection against chemicals and biologics, has a three-year shelf life, and highly efficient particulate filters.
Researchers found that female mice prefer outbred males with diverse major urinary proteins (MUPs) in their urine. This distinction allows females to 'count' the number of protein types, avoiding inbred males with less varied protein profiles.
Researchers found that oxygen atoms in yttria-stabilized zirconia can heal radiation-induced damage by moving into pre-existing vacancies. This self-healing behavior could lead to the development of radiation-resistant materials, improving durability and reducing replacement costs. The simulation results also suggest that this ceramic ...
A recent study published in the British Journal of Pharmacology has made a significant breakthrough in treating aortic valve stenosis, a common form of heart valve disease. The experimental treatment, which raises high-density lipoproteins (HDL), showed promising results, including reduced aortic valve narrowing and calcifications.
Researchers from Florida State University, Yale University, and Princeton University developed a new theory that analyzes music using geometry. The 'geometrical music theory' tool helps composers explore uncharted possibilities and musicians may be trained differently. It represents a culmination of the marriage between music and math.
A new study by the American Cancer Society found that female African American patients tend to overestimate their level of cancer screening. The study compared self-reported data with medical records and found significant discrepancies for some procedures, affecting estimates of screening rates.
NOAA researchers are part of the FISH-BOL initiative, a global effort to barcode marine and freshwater species. This allows for fast and accurate identification of species, including larval fish and fishery products.
A study found that severe housing damage is a key factor behind socioeconomic disparities in psychological distress after Hurricane Katrina. The research also revealed that blacks were substantially more likely to experience serious psychological distress, with almost one-third reporting high levels of distress.
Research suggests mammograms are effective for women aged 70-75, with a lower mortality rate compared to earlier age groups. The best interval for screening is every three years, which has been shown to be an appropriate upper age limit and saves lives without causing harm.
A study found that follow-up care for breast cancer patients costs less when led by nurses rather than physicians, with significant savings potential for healthcare budgets. Specialist nurse-led follow-up resulted in €866 per patient over a five-year period, making it a cost-effective alternative.
Researchers have discovered that Type IV pili on bacteria can bundle together and pull with forces far stronger than previously thought possible. This discovery sheds light on the role of pili in initiating infectious diseases such as tuberculosis.
Research challenges traditional views on homeworker isolation, finding that mobile connection can facilitate career progression and networking. Four interviewees expressed a desire for promotion and remained connected outside working hours.
A University of Michigan researcher is conducting a clinical trial to test the effectiveness of Zoloft on anxiety patients. The study aims to determine if genetic variations can predict an individual's response to anti-anxiety medication.
The 'GeparQuattro' trial shows that combining anthracycline and taxane chemotherapy with trastuzumab improves HER2 breast cancer response rates to 41.3%, compared to 19.5% without trastuzumab. The regimen also minimizes cardiac toxicity, making it a promising treatment option.
The Miami Youth Development Project is a community-supported program that targets risky behaviors while promoting positive self-development. The research draws on Developmental Intervention Science, which aims to promote both short-term and long-term life course changes.
