Studies look at how genes affect antipsychotic drug response

...linicians need to make sure they are appropriately monitored and treated as safely as possible. "Understanding risperidone pharmacogenetics and whether some individuals are at a higher risk for side effects is an important step in this process," he said. Risperidone is widely prescribed to treat bipolar di...

Fruit fly study identifies gene mutation that regulates sensitivity to alcohol

...chers exposed fruit flies to vaporized alcohol and monitored their behavior and motion patterns with sensitive tracking instruments. They isolated the flies that were less sensitive to alcohol's sedative effects. By breeding subsequent populations of mutant flies, the scientists identified the particular genet...

Monoclonal antibody reduces exacerbations in asthmatics

...moderate exacerbations in patients with asthma, as monitored by morning and evening use of an electronic spirometer incorporating a clinical diary," said Dr. Hansel. "Although infliximab therapy did not show significant efficacy for the primary endpoint of monitoring peak expiratory flow (PEF), it did produce ...

By 2048 all current fish, seafood species projected to collapse

...ated species diversity on small, local scales, and monitored the effects. Second, researchers tracked the 1,000-year-long history of change in species diversity and associated services across 12 coastal regions around the world. These included Chesapeake, Delaware, Massachusetts, Galveston, San Francisco Bay a...

Researchers show that veins stiffen as we age

...themselves." To find the answer, the researchers monitored the blood flow through each participant's veins in different scenarios that might constrict the veins, such as having one foot immersed in cold water, or while squeezing a handgrip. They also administered a nitroglycerin pill under the tongue of each...

Cryoablation -- A new treatment option for some kidney tumor patients

...Also, the area being treated cannot be effectively monitored with computed tomography (CT) or ultrasound. The ... (the edge of the frozen tissue) can be accurately monitored with CT, to ensure that the total tumor mass is treated. The researchers reviewed the records of ...

'Hidden-hero' microbes in soil, water may help naturally clean toxic sites

...ditions and pH adjustments. Subsurface changes are monitored using geophysical methods that send acoustic, electric and other signals into the ground. Kostka's research team from FSU's nationally top 10-ranked oceanography department will lead the "subsurface microbiology" portion of the ...

Triplex assay used to assay duplex genomic DNA

... in solution at room temperature. Reactions can be monitored after as little as five minutes. The highly sensitive diagnostic assay allows for the direct detection of base sequence in human genomic duplex samples, thereby obviating the use of PCR which has inherent problems and is costly. "We developed the he...

Racing neurons control whether we stop or go

... race model to existing data from experiments that monitored brain activity in monkeys while they were performing a visual stop signal task. In those experiments, the monkeys were taught to look at a visual target unless a stop signal came on, in which case they were supposed to refrain from looking at the tar...

UCSF brain tumor vaccine trial shows promising results

... second receives weekly vaccinations. Patients are monitored for immune response before, during and after treatment. The UCSF investigators will continue to follow patients for progression-free survival and overall survival. According to investigators, no adverse events or toxicity identified were considere...

Shedding new light on proteorhodopsin

...iratory poison azide." The Berkeley researchers monitored single cells of E. coli and observed the response to light of the proton motive force (pmf), the electrochemical potential of protons across cellular membranes that bacteria use as the energy source to, among other functions, power the rotary flagell...

A new study of living cells could revolutionize the way we test drugs

...? allowing the daily functioning of the cell to be monitored in a similar way to a cardiograph showing the workings of a human heart. With funding from the Engineering and Physical Sciences Research Council (EPSRC), Professor Andre Geim at the University of Manchester and his team have set out to make the f...

Helium helps patients breathe easier

..., while they exercised. During each test they were monitored for exercise time, breathing capacity, work of breathing and symptoms of exertion. The best results were achieved with a mix of 40 per cent oxygen and 60 per cent helium. The helium-hyperoxia mixture improved the exercise tolerance of the patients...

Biodiesel study targets cleaner air, cleaner engines

...horsepower and fuel efficiency. Environment Canada monitored exhaust emissions from tractors at the trial sites, including levels of carbon dioxide, nitrogen oxides and particulate matter. Although commercially available, biodiesel has never been tested on agricultural machinery in Canada and has not yet b...

Corals that can fight global warming may one day help fragile reefs

...nderstand how rising ocean temperatures (which are monitored with high-resolution satellite detectors) are related to lethal coral reef epidemics. The warm temperatures that have been occurring worldwide as a result of global warming appear to be facilitating fatal epidemics in coral reefs across the globe, ...

Early exposure to indoor fungus molecules may protect infants against future allergies

...ge. Environmental and food allergy development was monitored through annual skin prick tests. Scientists say early-life exposure to common microbial components—like bacterial endotoxins and fungal glucans—can stimulate the body’s immune system to produce infection- and allergy-fighting substances. Because o...

Snoring in children might be an allergic type disease

...rgic diseases in a group of children who have been monitored since before they were born. “Our findings were consistent with the view that snoring forms part of the spectrum of allergic diseases in childhood,” he said. While the study findings are limited to children with rhinitis, Dr Marshall explained ...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes

...ourse of each patient’s treatment, the researchers monitored blood counts, renal and liver function and clinical signs and symptoms. They then performed statistical analysis to assess which factors might have influenced patient outcomes. The median survival of all patients was 6.83 months. Patients with hig...
