A study analyzing cancer death records from 1989-2000 found no correlation between cancer mortality and holiday events like Christmas or birthdays. However, it did reveal a slight increase in cancer deaths among certain populations, such as black Americans before Thanksgiving and white women on their birthdays.
Scientists studying prion diseases in mice found that preventing cell death does not stop the progression of neurological symptoms. Damage to synapses, critical for nerve cell communication, is instead linked to the disease.
A study by Johns Hopkins Medicine found that pulsatile lavage equipment was the cause of an Acinetobacter baumannii outbreak, infecting 11 patients. The investigation led to changes in hospital procedures, including wearing masks and gloves during procedures and using private treatment rooms.
A study examining genetic factors in lung cancer found increased risks for first-, second-, and third-degree relatives of patients with lung cancer. The risk was stronger for early-onset disease, suggesting a possible genetic component beyond environmental factors.
Researchers found a significant increase in obesity (12% of men, 11% of women) and drinking (almost doubled in women with highest qualifications) among UK youth since the 1940s. Additionally, depression and anxiety rates have risen, with modern mothers less likely to breastfeed their children.
A study of 10,591 Taiwanese residents found that those exposed to high levels of arsenic in their drinking water had a 3.29 times increased risk of developing lung cancer. Cigarette smoking further exacerbated this risk, particularly among non-smokers and those with lower arsenic exposure.
Researchers analyzed death certificate data from Ohio between 1989-2000 and found no significant dip or peak in cancer deaths around Christmas, Thanksgiving, or birthdays. Women dying of cancer were more likely to die during the week before their birthday compared to men.
Nanotubes form along atomic steps due to iron nanoparticles' attraction to local fields created by the steps. The orientation and form of these steps can be controlled, enabling the production of different nanowire arrangements.
Researchers found that increasing one skill can significantly impact others, with some activities dropping and others increasing in levels. The primary function of the enzymes remained largely unchanged despite changes in other promiscuous traits.
A study by Johns Hopkins researchers found that doctors talk more to white patients than black patients during medical visits, leading to less engagement and participation. This difference in communication style contributes to health disparities among African-American patients.
Pharmacogenomics has the potential to improve treatment successes and reduce adverse reactions by targeting specific drugs at specific patients. The industry is expected to bear a larger share of costs associated with drug-treatment failures as well-targeted therapies become more commonplace.
Researchers at UCL found that brain activity increases in areas known as the 'mirror system' when experts view movements they've been trained to perform, compared to non-experts. This fine-tuned system may enable professionals to simulate skills without moving and maintain movement ability despite injury.
The St. Jude team determined the shape of CbpA, a large protein used by Streptococcus pneumoniae bacteria to invade human cells. This discovery will guide researchers in developing a new vaccine that can trigger production of antibodies against the CbpA protein.
A team of researchers led by Gary Gilliland discovered that certain leukemia oncogenes can reactivate self-renewal programs in mature white blood cells. This finding has significant implications for understanding and treating chronic myeloid leukemia, a disease fueled by a small population of cancer stem cells.
Researchers found that women experiencing menopause have reduced estrogen sensitivity in their brains, leading to increased hot flashes and night sweats. The study suggests that this insensitivity may contribute to menopause-related symptoms.
Researchers found that dreams up to a week after a memorable emotional event often reflect problem resolution and positive emotions. This suggests that dreams can serve as a treatment for working through personal difficulties.
A study found that acute eosinophilic pneumonia (AEP) was diagnosed in 18 US military personnel deployed to Iraq, with a high incidence rate of 9.1 per 100,000 person-years. All patients reported significant exposure to fine airborne sand or dust and used tobacco, but no common source exposure was identified.
Researchers tested devices outside of the body and found no interference, but warn that technology advances require continual testing for clinical safety.
A new technique developed by the University of Toronto team enables accurate measurements of individual exons that make up different mRNAs, opening doors to understanding more about some diseases. This process, known as alternative splicing, is a cellular process that acquires the ability to control genetic messages.
Researchers study the impact of hurricanes on coral reefs in South Florida, finding a temporary removal of invasive seaweed. However, experts caution that without addressing nutrient pollution and its root causes, reefs will remain vulnerable to similar problems.
A study found that only 12% of jails continued methadone treatments for withdrawal, while 48% failed to provide appropriate detoxification methods. The lack of coordination between jails and community clinics is a major concern.
The Journal of Dental Research (JDR) is now featuring manuscripts from Critical Reviews in Oral Biology & Medicine, enhancing its content and Scientific Impact Factor. The journal will also be made freely available online after 12 months.
A large study of 188 women found that nearly 55% with minimal unwanted hair growth had an androgen excess disorder, primarily polycystic ovary syndrome (PCOS). Women with PCOS often struggle with menstrual irregularities, skin problems, and excess weight.
