Because these data are being used to conduct public policy analysis and advice for Mexico and countries at similar levels of development, knowledge of the limits of these data is of utmost importance.(More)
The technique of Random Amplification Polymorphic DNA allows fragments of the genome to be amplified by means of polymerase chain reaction (PCR) without previous knowledge of their sequences. The protozoa of the genus Leishmania present great genetic variability, making it difficult to characterize the different species. A method is developed with a single(More)
Nassella is one of the largest genera in the tribe Stipeae with approximately 116 species, distributed from Canada to Uruguay and Argentina. Although there are strong morphological characters that distinguish this genus from the rest of the tribe, molecular phylogenetic analyses have shown that it is a polyphyletic genus closely related to Jarava and(More)
Abdominal ultrasonograms of recumbent, supine adult subjects were used to measure the angle formed between the horizontal plane and a plane along the anterior border of upper lumbar vertebral bodies. The angle, referred to as phi, for male and female subjects averaged 8.8 degrees. When this angle was compared in subjects with the hips flexed and extended,(More)
