Researchers studied rhesus macaques from birth to young adulthood, finding that those with high cortisol levels responded more strongly to stress and drank more alcohol as adults. The study's findings suggest early life stress can influence later alcohol consumption and offer a promising biological marker of risk.
A new Ohio University study found that weight training does not increase cholesterol levels in healthy young men and women, but reduces body fat and increases muscle strength. The research counters previous studies and news reports giving weight lifting a bad name.
A study found that faucet handles and phone receivers are high-risk areas for transferring bacteria and viruses to hands and faces. This could lead to diseases like diarrhea and infection if proper hygiene is not practiced. The researchers also highlighted the potential for household items like sponges and telephones to spread infections.
A Phase III trial shows long-term hormone suppression can control recurrence and improve survival in prostate cancer patients. The treatment significantly reduces disease-free survival, local progression, and freedom from distant metastasis.
A new study found that elderly men who rate their health as poor are more likely to die than women with similar ratings. Men's perceptions of their health are a better predictor of death risk, while women consider emotional distress from various factors, reducing accuracy in predicting mortality.
Researchers used a mouse model to identify changes occurring in nerve cells before the onset of Huntington's disease. They identified several signaling molecules that could be targeted for future therapies.
Researchers discovered a sub-group of alcoholics who self-medicate low serotonin levels with carbohydrates when not drinking. Carbohydrates increase serotonin levels, similar to alcohol, and this study provides insight into treating alcoholics with disturbed serotonergic function.
The company presented Phase II data of tgDCC-E1A, a lead cancer therapy, which showed a 45% objective response rate in patients with recurrent head and neck squamous cell carcinoma. Preclinical studies also demonstrated the ability of E1A to sensitize tumors to radiation and chemotherapy.
A study found that infant monkeys raised without adult supervision experienced higher cortisol levels, indicating increased stress, which later led to heavy drinking as adults. This suggests a link between early life experiences, sensitivity to stress, and subsequent alcohol consumption.
A Yale study found that older persons with acute illnesses prefer hospital care over home care, even if the outcomes are equally good. Home care is a viable option only if it provides the same level of care as the hospital.
Chronic alcohol consumption combined with thiamine deficiency may have a synergistic effect on the brain, causing impaired learning, reference memory, and cognitive functions. Thiamine supplementation can exacerbate this effect, and some experts suggest that food supplementation or beer enrichment may be more beneficial.
The X-40A test vehicle, built by Boeing, is being shipped to NASA's Dryden Flight Research Center at Edwards, Calif., for a series of ground and air tests. The X-37 project aims to demonstrate technologies in the orbital and reentry environments for next-generation reusable launch vehicles.
Scientists at Northwestern University discovered that polyglutamine aggregates are toxic and can bring healthy proteins to aggregate with them. The growth of these aggregates can be suppressed by molecular chaperones called heat shock proteins. This finding provides a new model for understanding the common pathology of neurodegenerativ...
Researchers will grow functional human heart tissue, aiming for a fully functional heart in 10 years. They'll use scaffolding, stem cells, and patented technology to engineer cardiac muscle and valves.
Researchers found that watching the video reduced anxiety and stress in patients before surgery, while also decreasing cortisol levels and pain medication needs. The study suggests that preparing for an operation by watching a videotape may improve coping abilities.
A new study shows Bexxar produced tumor shrinkage in 97% of patients with advanced-stage, low-grade non-Hodgkins lymphoma. Most patients achieved complete remission, with no sign of cancer, and molecular remissions lasting up to three years.
The data from an ongoing Phase 1/2 trial of O-Vax in patients with advanced ovarian cancer indicates that the vaccine induces a positive immunological response, as measured by a delayed type hypersensitivity test. Favorable clinical responses were also observed, including complete regression of tumors and normalization of CA-125 levels.
A study found that recently detoxified male alcoholics experience significant cognitive and motor deficits, particularly in gait and balance. These impairments can lead to an increased risk of falls and may be linked to the 'premature aging hypothesis,' where the brains of older alcoholics resemble those of non-drinkers.
A new University of Florida study reveals that consuming folate-rich foods daily can significantly reduce homocysteine levels, a risk factor for heart disease, in postmenopausal women. The research suggests that improving folate intake is crucial for older women's health.
Scientists at Max Planck Institute discover novel potassium current activated by calcium, shaping neural signal frequency. SK channels play a crucial role in neuronal adaptation, influencing brain function and learning. The study resolves a long-standing controversy between electrophysiology and apamin-binding studies.
The Pew Fellows Program in Marine Conservation awards $150,000 to ten ocean ambassadors from five continents tackling pressing issues like marine pollution and coastal conservation. The 2000 recipients will conduct interdisciplinary projects applying sound science to urgent challenges.
A recent study of female participants with functional gastrointestinal disorders found that catastrophizing and low perception of power over symptoms worsened health outcomes. The researchers suggest that cognitive behavioral therapy may help alleviate these negative coping strategies and improve gastrointestinal symptoms.
Researchers have identified a water extract from potatoes that inhibits the attachment of certain bacteria, such as oral streptococcus and E. coli, to their target tissue. This finding could provide a new direction for antibiotic research and potentially help solve the growing problem of antibiotic resistance.
