South Africa Launches HIV/AIDS Vaccine Trial
"The first clinical trial of an HIV/AIDS vaccine designed and developed in South Africa was launched in Cape Town" Monday, the SAPA/The Times reports. The trial will seek to determine the immune response of HIV-negative people to two experimental vaccines - SAAVI DNA-C2 and SAAVI MVA-C (7/20). Similar tests of the vaccine began in the U.S. earlier this year, the AP/Washington Post reports. According to Anthony Mbewu, president of South Africa"s government-supported Medical Research Council, the vaccine was designed at the University of Cape Town with technical help from the NIH, which also manufactured the vaccine (Faul, 7/20). Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, called the partnership between South Africa and the U.S. "the most important AIDS research partnership in the world," but cautioned the years ahead would prove challenging as researchers test the safety and efficacy of the HIV vaccine, the AP/Google.com reports (Faul, 7/20).

Ohio Supreme Court Restricts Mifepristone Use In State To Scope Of FDA's Approval Letter
In answering two certified questions from the U.S. Court of Appeals for the 6th Circuit, the Ohio State Supreme Court on July 1 declared that a state law regulating the use of mifepristone -- which is used in medication abortion -- bars physicians from prescribing it for off-label use, BNA reports. The court confirmed that doctors who use the drug to induce abortion must do so in compliance with the 49-day gestational limit included in FDA"s 2000 drug approval letter. Doctors also must prescribe the drug in accordance with the protocols and dosage indications included in its FDA-approved labeling.Interpretation of State Law in ContentionThe Ohio General Assembly in 2004 passed a law (Section 2919.123 (A)) that required any health care professional prescribing or dispensing mifepristone to comply with "all provisions of federal law that govern the use" of the drug. The law defines "federal law" as "any law, rule or regulation of the United States or any drug approval letter" from FDA "that governs or regulates the use of" mifepristone for inducing abortion. FDA"s approval letter states that the drug "is indicated for use in the termination of pregnancy (through 49 days" pregnancy) and has no other approved indication for use during pregnancy." In addition, the drug"s label states the recommended dosage and that its use requires three office visits by the patient. Planned Parenthood Southwest Ohio Region challenged the law in district court, arguing that neither FDA"s approval letter nor any other federal provision bans the off-label use of mifespristone to induce abortion beyond 49 days" gestation. The group also argued that the state law was unconstitutionally vague because it did not notify abortion providers in advance regarding which FDA documents were included in the state"s criminal law. In addition, Planned Parenthood said that prohibiting the evidence-based use of the drug would infringe on the rights of women, requiring them to take higher-than-necessary dosages of the drug or to undergo surgical abortions when a noninvasive alternative is available. The district court ruled in favor of Planned Parenthood, saying that the law was void because of vagueness. The state appealed the decision to the 6th Circuit, which then submitted two questions to the state Supreme Court seeking its interpretation of the law.The state Supreme Court ruled that FDA"s drug approval letter is included in the definition of "federal law" and that the state law is not ambiguous, according to BNA. The court said that because the drug approval letter incorporated FDA"s labeling text, Ohio physicians cannot prescribe or provide mifepristone to induce abortion outside of the stipulations of the drug approval letter and approved label. According to BNA, product liability law experts say the ruling will not have an impact outside of mifepristone or the state of Ohio.Case Returns to Appeals CourtRoger Evans of Planned Parenthood Federation of America said that he is not sure if the court"s decision helps or hurts the group"s case. Evans said that the district court declared the law unconstitutional based on an interpretation that the statute operates in the same way the state Supreme Court ruled it does. He noted that there are other possible interpretations of the law that would have solved the constitutional issues at the center of the litigation. However, because those issues were not resolved, the case now returns to the 6th Circuit, which will decide if the statute is constitutional based on the state Supreme Court"s interpretation. If the circuit court agrees with the district court that the statute is unconstitutionally vague, the state of Ohio could seek a U.S. Supreme Court review. If the circuit court finds that the statute is constitutional, the case likely will be sent back to the district court for resolution of some other issues in the case, according to BNA (BNA, 7/6).

The Fancier The Cortex, The Smarter The Brain?

Why are some people smarter than others? In a new article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, Eduardo Mercado III from the University at Buffalo, The State University of New York, describes how certain aspects of brain structure and function help determine how easily we learn new things, and how learning capacity contributes to individual differences in intelligence. Cognitive plasticity is the capacity to learn and improve cognitive skills such as solving problems and remembering events. Mercado argues that the structural basis of cognitive plasticity is the cortical module. Cortical modules are vertical columns of interconnected neuronal cells. Across different areas of the cerebral cortex, these columns vary in the number and diversity of neurons they contain. Identifying how cortical modules help us learn cognitive skills may help explain why variations in this capacity occur - that is, why people learn skills at different rates and why our ability to learn new skills changes as we age. Studies examining a number of different species have shown that, on average, a larger cortex predicts greater intellectual capacity. The of this correlation is unclear, but Mercado believes that a "more expansive cortex provides more space within which a larger quantity and greater diversity of cortical modules can be distributed." In other words, Mercado notes that when it comes to intellectual potential, it is not the absolute or even relative size that is important, but how many cortical modules (with various types of neurons) are available. These features of cortical organization and function determine how effectively our brain distinguishes events. This ability to differentiate events may be what enables us to learn cognitive skills. One implication of this proposal is that experience can be as important as genetics in determining intellectual capacity. Specifically, structural changes of cortical modules generated by development and learning experiences may also contribute to individual differences in intelligence. As these networks of neurons develop over time, their diversity increases, leading to further increases in cognitive plasticity. This research has important implications for improving educational techniques and can potentially lead to new methods for rehabilitating patients suffering from brain damage. In addition, understanding how cortical modules function may lead to new ways of increasing intelligence. However, Mercado cautions that "new technologies for increasing cognitive plasticity have ethical implications far beyond those raised by doping in sports." He concludes, "The phrase "changing your mind" may soon take on a whole new meaning." Barbara Isanski Association for Psychological Science
