Research by UCLA chemists suggests that too much Coenzyme Q can be harmful to adult worms, extending their life span. The study, published in the journal Science, found that lower amounts of Coenzyme Q significantly extended the life span of Caenorhabditis elegans worms.
A new UCLA imaging study has found that placebo alters brain function in individuals with major depression, showing increased activity in the prefrontal cortex for those who responded to treatment. This discovery challenges traditional views on treatment effectiveness and may lead to the development of new medications.
Researchers found a significant link between exposure to high levels of ozone and carbon monoxide during the second month of pregnancy and an increased risk of conotruncal heart defects. The study analyzed data from over 9,000 babies born in Los Angeles and found that women exposed to elevated pollution levels were three times as likel...
The UCLA Basic Plasma Science Facility has been awarded a $4.8 million grant to conduct controlled experiments on plasma, a fourth state of matter. The Large Plasma Device (LAPD) machine allows physicists to create and analyze superheated, energized gas, with potential applications in fusion energy, computer chips, and waste destruction.
UCLA researchers found that anxiety about breast self-examination leads to low compliance among high-risk women. Only 34% of participants performed regular breast self-exams, despite high rates of mammogram and Pap smear adherence.
Researchers at UCLA's Jonsson Cancer Center have discovered the PTEN gene's role in regulating brain stem cells, finding that its absence disrupts normal growth and proliferation. The study suggests that PTEN is a critical regulator of brain stem cell behavior, which may contribute to tumor formation.
A new study by UCLA researchers has created images showing how an individual's genes affect their brain structure and intelligence. The findings, published in Nature Neuroscience, reveal that genetic differences can significantly impact brain regions controlling language and reading skills.
A UCLA/VA neuroscientist's review of REM sleep studies reveals that sleep is not necessary for memory formation. While sleep loss can affect concentration and performance, it does not appear to be essential for learning.
Researchers will combine surgical robotic systems with telemedicine to train surgeons-in-training in complex, minimally invasive procedures. The proposed system will feature shared control of a single set of 'arms' and haptic feedback for immersive training.
A study of 13 HIV-positive men found that those with high levels of autonomic nervous system activity responded less well to antiretroviral treatment, with some experiencing no immune recovery. Stress accelerates AIDS progression by increasing viral replication and making it harder for the body to fight off the infection.
Researchers found Thrombospondin-1 (TSP1) regulates tumor growth by suppressing MMP9 activation, which promotes angiogenesis. The discovery could lead to new treatments targeting malignancies by cutting off the blood supply to tumors.
Scientists at UCLA and NIMH detected a spreading wave of gray matter loss in schizophrenic patients, which engulfed the brain over five years, leading to worse symptoms. The study's findings may aid early detection and treatment, as well as inform future medication development.
Researchers predict that 42% of all HIV cases will be drug-resistant by 2005, mainly due to the conversion of drug-sensitive cases during antiretroviral therapy. The study recommends four epidemic-control strategies to minimize prevalence and transmission of drug-resistant HIV.
UCLA researchers have discovered a unique gene modification that may be the cause of certain types of lymphoma. The discovery, which involves DNA methylation, could lead to new treatments for these types of cancer.
Researchers identified a small group of neurons responsible for issuing breathing commands within the preBotzinger Complex. Destroying these neurons in rats resulted in irregular breathing patterns and impaired oxygen control, suggesting they hold underlying causes of breathing disorders.
Researchers suggest that Yasmin, with its unique progestin ethinyl estradiol combination, holds promise for reducing PMDD symptoms and improving women's lives. A three-month study found that 82 women taking Yasmin showed greater improvement than the placebo group.
A recent study found that adolescents who participated in community-based treatment programs significantly reduced drug use and criminal behavior, and improved academic performance. Longer stays in treatment were associated with better outcomes.
Biologists from UCLA and Swedish universities have uncovered the history of how wild horses were domesticated, revealing widespread interbreeding across multiple regions. The study found that genetic diversity was much higher than previously thought, suggesting a more complex process of domestication.
Researchers from UCLA and Curtin University of Technology found ancient zircons in a rock that suggest liquid water existed on Earth's surface around 4.3 billion years ago. This discovery supports the idea that the conditions for life were met early on, possibly allowing for the emergence of life as early as 4.3 billion years ago.
The researchers designed and made a rotaxane-based nano motor powered by sunlight, which operates according to a four-stroke cycle. The system works continuously without consuming chemical fuels or generating waste.
A new UCLA study suggests that a high-fat diet may contribute to the development of osteoporosis by reducing bone density and mineral content. The research, published in Journal of Bone and Mineral Research, could lead to new treatment options for osteoporosis, a disease affecting over one million people annually.
Researchers at UCLA and NASA are creating a robotic stepper device that uses precise measurements to help therapists monitor patients' progress in rehabilitation. The device could enable some wheelchair-bound individuals to learn to walk again or improve their walking ability, according to the researchers.
A study by UCLA researchers found that androstenedione supplements can contain a contaminant linked to banned steroid nandrolone. The study tested 37 healthy men, revealing that 20 of their urine samples contained enough 19-norandrosterone to test positive for steroid use.
A study published in Nature reveals that individual neurons in the human medial temporal lobe selectively alter their firing rates depending on the stimulus the subjects imagined. This discovery sheds new light on how the 'mind's eye' works, providing insight into the neural mechanisms underlying visual recall and imagery.
A new UCLA study reveals an inverse relationship between depression and strong ties to the African American community, independent of demographic and health factors. Women with strong ethnic identity experienced lower levels of depression and less excess weight.
Researchers at UCLA have discovered a new treatment that can reverse heart damage in children with acute myocarditis, an infection of the heart. The study used OKT3, an immunosuppressive treatment, to suppress the immune response and improve heart function in five critically ill children.
Researchers at UCLA and Cambridge report a breakthrough in pain medicine that delivers painkillers directly to affected areas, eliminating unwanted side effects. A single injection of the new medication can alleviate pain for several days, offering a significant improvement over current treatments.
UCLA researchers found that nicotine causes selective degeneration in the fasciculus retroflexus pathway, a region linked to drug addiction and relapse. High doses of nicotine led to almost complete degeneration in this pathway, highlighting its vulnerability to stimulant drugs.
