A procedure is described for the isolation of native DNA from protoplasts of ammi (Ammi visnaga) and carrot (Daucus carota) cells. Protoplasts were produced from 40 grams of fresh cells by enzyme hydrolysis and lysed with sodium dodecyl sulfate. The DNA was purified by treatment with pronase and ribonuclease. Final isolation was achieved by sucrose density gradient centrifugation.The melting te...

Background: Breast milk provides adequate protein to facilitate growth for term infants. Appropriate nutrition is necessary for the growth of preterm infants. Extremely-low-birth-weight (ELBW) infants require higher protein intakes to achieve adequate growth. The present study aimed to evaluate the effect of protein supplements on the physical growth of infants weighing less than 1,000 grams t...

Initially poorly conducting PbSe nanocrystal solids (quantum dot arrays or superlattices) can be chemically "activated" to fabricate n- and p-channel field effect transistors with electron and hole mobilities of 0.9 and 0.2 square centimeters per volt-second, respectively; with current modulations of about 10(3) to 10(4); and with current density approaching 3 x 10(4) amperes per square centime...
