A new study published in Pediatrics reveals a strong link between teenage smoking and depressive symptoms, with non-depressed teens who smoke facing a four times greater risk. Social factors such as peer tobacco use, poor school performance, and parental report of bad temper also predict progression to heavy smoking.
A six-month study confirms that antibiotic choice significantly impacts long-term patient outcomes for acute infections, with gemifloxacin reducing hospitalizations and recurrences of chronic bronchitis. The study found a 30% lower rate of recurrence in patients treated with gemifloxacin compared to clarithromycin.
Critics argue that the 1990 Act has shifted protection focus towards rehabilitation, allowing more abuse to occur. The number of children placed in care fell by a third, but this decline is attributed to social workers' reluctance to intervene rather than a decrease in abuse.
A large-scale study suggests that coffee drinkers are at a higher risk of developing rheumatoid arthritis. The research found that those who consumed four or more cups of coffee daily were twice as likely to test positive for the disease, while those who drank 11 cups or more were nearly 15 times more likely.
A study of over 300 heart attack survivors found that only one in four called for help within an hour, while 12% delayed more than 24 hours. Prompt treatment can halve the risk of death from a heart attack, highlighting the importance of swift medical attention.
A study found that young women with heart disease experience worsening exercise performance and angina pain in the early follicular phase, just after menstruation, but improved performance and slower pain onset in mid-cycle. Sex hormones may play a role in these fluctuations.
The ACM SIGCOMM 2 000 conference was held in Stockholm, Sweden, gathering researchers from USA and Europe to discuss network security, Internet telephony, and other topics. Notable speakers included Prof. André Danthine, Dr. Radia Perlman, and Professor Henning Schulzrinne.
The report reveals big variations between countries, with France, Germany, and the UK carrying out more than half of all IVF treatments. Scandinavian countries and the Netherlands have the highest availability of IVF treatment, resulting in a significant number of children being born through IVF.
Researchers are using lasers to aid embryonic development by precision-drilling the 'shell' of human eggs. This technique has shown improved IVF success rates and increased implantation rates, allowing embryos to embed themselves in the womb more effectively.
Researchers found that ERT increased blood flow to areas involved in memory formation, such as the hippocampus and parahippocampal gyrus. The study suggests ERT may lower susceptibility to age-related memory problems and Alzheimer's disease.
Researchers develop novel method of membrane fusion to transfer infertile woman's nucleus into donor egg, enabling nearly full genetic contribution. The technique could help women with embryo development failures due to cytoplasmic defects in their own eggs.
Researchers have found that most of the interstellar dust particles consist of 3-dimensionally cross-linked organic macro-molecules, called polymeric-heterocyclic-aromates. These molecules have been detected in five impact mass spectrometer samples from NASA's STARDUST spacecraft.
Researchers are exploring alternative methods for delivering drugs, including handheld electronic inhalers, dry powder injection and implantable microchips. These innovative systems have the potential to deliver precise doses of medication in a faster and more efficient manner than traditional hypodermic needles.
The Catalyst study found that over half of the women scientists interviewed preferred industry careers due to a lack of information about corporate job markets. Many reported feeling unwelcome in academic environments, leading them to pursue careers in applied science and product development. To address this issue, companies are advise...
A Canadian study found that university-educated white-collar women experience significant increases in blood pressure due to office stress and large family responsibilities. The research revealed a persistent effect of these factors on blood pressure throughout the day, evening, and night.
Researchers found that Chlamydia proteins can trigger an autoimmune response in the host, leading to inflammation of the heart. The link between Chlamydia and heart disease appears to involve an autoimmune disorder, with similar proteins on the pathogen's surface matching those found in human heart muscle.
The Gallup survey reveals that 77% of American moms whose preschool children have suffered from ear infections are concerned about the long-term effects. Despite this, many parents are unaware of how to detect middle ear fluid, which can cause complications such as hearing loss and speech delays.
A significant proportion of individuals within the low risk population test positive for HIV-1 antibodies in their urine and negative in their blood. The presence of antibody against HIV-1 in the urine indicates prior exposure to the virus, suggesting a need for both blood and urine screening.
A study found that inhaled zanamivir significantly reduces the time to recover from influenza symptoms by up to one-third and complications by 71% in high-risk patients. It also showed faster return to normal activities and better health status scores compared to placebo.
A study discovered that individuals carrying a genetic variant in the CYP2A6 enzyme break down nicotine more slowly, leading to greater resistance to nicotine addiction. This finding suggests that medications targeting the enzyme may help prevent and treat nicotine addiction.
A new study analyzes US hurricane damage data, normalizing for inflation, coastal population increase, and wealth. It finds that landfalling hurricanes in the 1940s-1960s would have produced over $10 billion in damages if they struck today, contradicting claims of climate change causing recent damage increases.
Research suggests that neighborhoods with high poverty rates have significantly higher rates of domestic violence, particularly involving intimate partners. The study found that nine times more incidents of assaultive violence occurred in these areas compared to non-poverty neighborhoods.
The Virginia Tech project aims to develop a National Digital Library of Theses and Dissertations, increasing accessibility of graduate research results. With federal funding, over 40 institutions will benefit from electronic thesis submission and retrieval, enhancing knowledge transfer.
Two new classes of organic compounds show promise in limiting damage caused by lung disease and other inflammatory diseases. By blocking enzymes that cause connective tissue damage, the compounds reduce inflammation and potentially prevent further tissue harm.
Researchers at Virginia Tech have developed a safer wireless antenna design called Safetenna. Safetenna eliminates transmission in the direction where the signal would be blocked by the user's head, reducing harmful absorption of power by the body. The new technology demonstrates improved performance with no trade-off on safety.
Researchers are investigating alternative methods to stabilize seemingly chaotic oscillations in experimental nerve cell and heart preparations. They aim to improve treatments for arrhythmia by controlling chaos in the heart's upper chambers, which can lead to conditions like atrial fibrillation.
