Fertility Prediction Kit Ovu-Trac(R) By OvumOptics Harnesses The Testing Power Of Saliva Testing
Saliva sample testing is fast becoming the diagnostic data collector of choice in a variety of medical testing. Over the past two years, American scientists are turning more to the accuracy of results in saliva sample tests, more than traditional blood and urine tests. Ovu-Trac® is at the leading edge of this scientific knowledge with its ovulation test and predictor kit. These fertility test kits can help women who are trying to conceive a child determine when they are ovulating.

Federal Official Comments On HIV Travel Ban, Needle Exchange In U.S. At Conference
National Institute of Allergy and Infectious Diseases Director Anthony Fauci told delegates at the 5th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention in Cape Town, South Africa "that a bill to lift the ban on funding needle exchange programmes was working its way through Congress, and restrictions on HIV-infected people entering the U.S. were also almost certain to be lifted in the near future," Plus News/IRIN reports. Fauci added, "With regard to science and policy, we will stay on the right path." Eric Goosby, the U.S. Global AIDS Coordinator, was also present at the conference and discussed U.S. policies related to global HIV/AIDS (7/20).

Discovery Of Fetal Short-Term Memory In 30-Week-Old Fetuses

Memory probably begins during the prenatal period, but little is known about the exact timing or for how long memory lasts. Now in a new study from the Netherlands, scientists have found fetal short-term memory in fetuses at 30 weeks. The study provides insights into fetal development and may help address and prevent abnormalities. Published in the July/August 2009 issue of the journal Child Development, it was conducted by researchers at Maastricht University Medical Centre and the University Medical Centre St. Radboud. The scientists studied about 100 healthy pregnant Dutch women and their fetuses, measuring changes in how the fetus responds to repeated stimulation. After receiving a number of stimuli, the fetus no longer responds to the stimulus as observed by ultrasonography and the stimulus is then accepted as "safe." This change in response is called "habituation." In a second session, the fetus "remembers" the stimulus and the number of stimuli needed for the fetus to habituate is then much smaller. Based on their research, the scientists found the presence of fetal short-term memory of 10 minutes at 30 weeks. They determined this because a significantly lower number of stimuli was needed to reach habituation in a second session, which was performed 10 minutes after the first session. They also found that 34-week-old fetuses can store information and retrieve it four weeks later. Fetuses were tested at 30, 32, 34, and 36 weeks, and again at 38 weeks. The 34- and 36-week-old fetuses habituated much faster than the 38-week-old fetuses that had not been tested before. This implies that these fetuses have a memory of at least 4 weeks - the interval between the test at 34 weeks and that at 38 weeks. "A better understanding of the normal development of the fetal central nervous system will lead to more insight into abnormalities, allowing prevention or extra care in the first years of life and, as a consequence, fewer problems in later life," according to the study"s authors.
