We projected tuberculosis incidence, prevalence, and mortality in each World Health Organization region from 2010 to 2050, and incorporated changing trends in smoking, case detection,...

Retinopathy is a common cause of blindness in all age groups. There are 15 million people in the United States with age-related macular degeneration (AMD)—20% of those aged 65 to 74 years and 30% aged
74 years—and 1.6 million of those have neovascular (wet) AMD. In the working age population there are
20 million (
7% of the population) with diabetes, and 50% of patients with diabetes mellitus have diabetic retinopathy (DR) after 25 years. In children, retinopathy of prematurity (ROP)...

In recent years, parents in the United States and worldwide have purchased enormous numbers of videos and DVDs designed and marketed for infants, many assuming that their children would benefit from watching them. We examined how many new words 12- to 18-month-old children learned from viewing a popular DVD several times a week for 4 weeks at home. The most important result was that children who viewed the DVD did not learn any more words from their monthlong exposure to it than did a...

Further studies have shown that the NC cells which participate in facial skeletogenesis correspond to the anteriormost region of the body axis where the genes of the Hox cluster are not expressed. If the forced expression of Hoxa2, Hoxa3 and Hoxb4 (the most anteriorly expressed Hox genes) is induced in this part of the neural fold, brain development is deeply affected with anencephaly and no skeletogenesis takes place in the face which fails to develop. This phenotype is reproduced when the...

A proposal for an interactive process that integrates myth and science regarding water-culture awareness. If science and myth are reconciled, we believe that synthesis can occur within communities in ways that enable collaboration, trust building, and local water policy change, especially where common pool resources are a concern.

This video shows the life cycle of the sea biscuit Clypeaster subdepressus and is part of my master's thesis project at the Biosciences Institute of University of São Paulo. We collected adults from sand beds of São Sebastião Channel (São Sebastião, SP, Brazil) and induced gamete release (eggs and sperm). We did the fertilization in vitro and followed the embryonic development in the laboratory, under light microscopy. Embryos become swimming larvae, approximately 0.2 mm wide,...
