Legumes (Fabaceae or Leguminosae) are unique among cultivated plants for their ability to carry out endosymbiotic nitrogen fixation with rhizobial bacteria, a process that takes place in a specialized structure known as the nodule. Legumes belong to one of the two main groups of eurosids, the Fabidae, which includes most species capable of endosymbiotic(More)
OBJECTIVE To develop a statewide school-based program of measuring and reporting cardiovascular fitness levels in children, and to create age- and sex-specific cardiovascular fitness percentile-based distribution curves. STUDY DESIGN A pilot study validated cardiovascular fitness assessment with Progressive Aerobic Cardiovascular Endurance Run (PACER)(More)
We present the case of a 15-year-old with a cerebellar infarct that involved multiple arterial territories. It was temporally related to, and probably caused by, heavy marijuana use. While the mechanism of marijuana-associated stroke is unclear, the drug is known to cause hypotension and to impair peripheral vasomotor reflexes. We suspect that the child had(More)
With the introduction of massively parallel, microminiature-based instrumentation for DNA sequencing, robust, reproducible, optimized methods are needed to prepare the target DNA for analysis using these high-throughput approaches because the cost per instrument run is orders of magnitude more than for typical Sanger dideoxynucleotide sequencing on(More)
OBJECTIVES HIV infection is associated with a higher prevalence of low bone mineral density (BMD) and fractures than that found in the general population. There are limited data in HIV-positive adults, naïve to antiretroviral therapy (ART), with which to estimate the relative contribution of untreated HIV infection to bone loss. METHODS The primary(More)
The leptin-regulated melanocortin (MC) system modulates energy homeostasis and hypothalamic MC neuronal circuits regulate insulin secretion. We therefore hypothesized that MC system components were present in the pancreas. In order to determine the veracity of the hypothesis, we examined c-Fos, melanocortin-4 receptor (Mc4r), and(More)
Case histories of 47 children with strict criteria for Landry-Guillain-Barré-Strohl polyneuritis admitted to a rehabilitation facility from late 1959 through 1972 were analyzed retrospectively. The children were followed to full recovery (good to normal strength in all muscle groups) or for three years without full recovery. The data were then compared(More)
