Second-generation Antidepressants Very Similar But Have Different Side
Because clinical depression is so disabling and affects more than 16 percent of adults in the United States at some time in their lives, researchers have worked hard to develop more effective treatments. But how much better are the newer pharmaceuticals? Technology That Could Double The Effectiveness Of Cancer Drugs Studied
To identify the best treatment for recurrent ovarian cancer, researchers at Yale School of Medicine are studying a technology called the Yale apoptosis assay in combination with another technology called the ChemoFX assay, which could double the response rate to existing drugs. Cockroaches Are Morons In The Morning, Geniuses In The Evening
In its ability to learn, the cockroach is a moron in the morning and a genius in the evening. Dramatic daily variations in the cockroach's learning ability are reported in a new study. The few studies that have been done with mammals suggest their ability to learn also varies with the time of day. For example, a recent experiment with humans found that people's ability to acquire new information is reduced when their biological clocks are disrupted, particularly at certain times of day. Stop Eating For Two: Obese Moms-to-be Should Gain Less Weight Than Cur
A new study suggests current guidelines for weight gain during pregnancy should be revised. Severely obese women should lose weight during pregnancy, while obese women who are pregnant should gain less weight than currently recommended, according to new research. The findings run counter to current recommendations developed by the Institute of Medicine in 1990 that suggest women should gain at least 15 pounds during pregnancy and places no upper limit on pregnancy weight gain. Adults Living With Children Eat More Fat Than Do Other Adults
Adults living with children eat more saturated fat -- the equivalent of nearly an entire frozen pepperoni pizza each week -- than do adults who do not live with children, according to a University of Iowa and University of Michigan Health System study. Artist/Scientist 'Dream Team' Assembles With Goal Of Capturing And Dis
An eclectic group of artists and scientists that organizers have dubbed the "dream team"of imaging and visualization gathered at New York University recently to begin to create a photographic system capable of capturing and displaying a gigapixel -- one billion pixels -- of visual information in a single image. Office of Cannabis Medical Access [Canada]
This Canadian government office "coordinates the development and administration of the regulatory approach permitting individuals to access marihuana (cannabis) for medical purposes."The site provides quick facts about the Marihuana Medical Access Regulations, the text of laws and regulations, guides and forms, information for patients and medical professionals, statistics (authorized users and producers and applications), and related information. In English and French. From Health Canada. NYU's Center For Comparative Functional Genomics Helps To Unravel The
MicroRNAs are a recently discovered large class of small, non-coding genes. Each animal genome contains hundreds of these genes, which have been shown to regulate the expression of protein coding genes by binding to partially complementary sites in messenger RNAs. However, little is known about the biological function of these tiny genes, which are encoded in a string of 21 to 24 DNA bases. Alcoholics Have A Greater Chance Of Infection Following Cardiac Surger
Long-term alcoholics are known to have a greater risk of disease and death following surgery. A new study examines the risk of infection following elective cardiac surgery. Results show that long-term alcoholics have a four-fold increased rate of postoperative infections, an increased length of need for mechanical ventilation, as well as a need for prolonged treatment in the intensive care unit. Sensor Technology At Case Western Reserve University Can Help Uncover
In a world with an intensified need for security, Case Western Reserve University researchers are developing materials that could make consumers less susceptible to product tampering or failures. Using a mixture of conventional polymers with small amounts of tailored fluorescent dyes, Case researchers have discovered that the dyes function as natural, molecular sensors, creating light-emitting polymer blends that show mechanical stress by changing colors when a material is deformed.
