A 30-year-old woman developed ataxia and nystagmus after using an herbal supplement for weight loss, leading to a diagnosis of Wernicke's Encephalopathy. The woman responded positively to daily thiamine injections, resolving her symptoms.
Satellite observations show northern regions experiencing a 'greening' trend over the past two decades, with spring advancing by about a week and summer maximum leaf cover increasing. The LPJ model confirms this trend, attributing it to warming caused by climate change, while also highlighting other factors such as increased carbon dio...
Researchers created mice with human alpha-synuclein gene to study MSA pathology. Healthy cells do not produce this protein, while affected cells form insoluble inclusion bodies.
Researchers investigate how reducing serotonin levels affects people with and without depression. The study uses tryptophan depletion to temporarily lower serotonin levels in participants, aiming to discover new ways to predict who is at risk for major depression and when treatment can be safely discontinued.
Researchers have developed a way to modify genes that create maytansinoids, potentially making them more effective against tumors and better tolerated by patients. The technique uses genetic engineering to alter the chemical structure of the anti-cancer agents, reducing toxicity and improving efficacy.
A new natural family planning method, the Standard Days Method, is more than 95% effective in preventing pregnancy. This method uses a color-coded bead system called CycleBeads to track ovulation and identify fertile days.
The proposed system uses autonomous spaceships to transport crews between Earth and Mars, enabling frequent 5-month trips. The design architecture includes Astrotels and Taxis, which will facilitate sustainable Mars habitation and exploration.
Researchers from Cornell University deployed acoustic recording units to capture sounds from the Pearl River drainage, but found no indication of the ivory-billed woodpecker's presence. The technology may provide conclusive evidence on future sound recordings.
The American Academy of Neurology endorses electrodiagnostic tests for diagnosing carpal tunnel syndrome (CTS). These tests offer a high degree of sensitivity and specificity. The guideline recommends laboratory studies for confirming the clinical diagnosis of CTS due to its importance in treating patients who frequently require surgery.
A natural compound found in tomatoes has been patented and licensed for production as an insect repellent. The substance, IBI-246, is considered slightly safer than DEET and repels a range of insects, including mosquitoes, ticks, fleas, and biting flies.
A new study by UCSF researchers reveals that osteoporosis has significant economic costs for Californians, with Medicare paying for most hospital care and nursing home care being the largest expense. Early detection and prevention are critical to reducing these costs, which include indirect losses due to premature death.
A common soil bacterium produces a toxin that kills zebra mussels, causing major problems in water-dependent infrastructure. Preliminary tests indicate the microbe does not harm other species, paving the way for commercialization and potential use as an eco-friendly control agent.
A recent study by the University of Southern California reveals that breast cancer incidence rates have increased significantly among Asian-American women, particularly those of Japanese descent. The study found that breast cancer rates for Japanese and Filipino women were about double those for Chinese and Korean women.
A study found that sisters of centenarians have about half the risk of dying at any given age compared to the national average. Brothers of centenarians also exhibit low mortality rates, especially during young adulthood, increasing their chances of becoming centenarians.
The new guidelines stress the importance of inhaled corticosteroids for controlling and preventing asthma symptoms. The update also highlights the need for further research on combination therapy, particularly in young children.
Researchers have developed a new technique using the vascular endothelial growth factor (VEGF) as a carrier to deliver a toxic agent selectively to tumor blood vessels. This approach has shown impressive anti-tumor effects in mice with human melanoma and prostate cancer, reducing tumor growth by up to 16 percent.
