  • Dihaploid lines of tobacco (Nicotiana Tabacum L.) were developed from vitro anther culture of single cross F 1, "SC 72"X "Hicks". All genetic materials were evaluated for agronomic performance and chemical composition. Compared with midparent value, pollen derived dihaploid progenies showed reduced vigor in all measured features of plant growth, and increased total alkaloids as well as decreased reducing sugar content.

  • Biopharmaceuticals, with their ability to treat many unmet needs, are seen as promising medications in diabetes mellitus, growth hormone deficiency, chronic renal failure, cancer, and rheumatoid arthritis. However, almost all biopharmaceuticals should be administrated by injection; IV, IM, and SC. In addition, these treatments are long term, and patients should receive frequent injections for many years. Patient compliance is therefore of critical importance to ensure treatment benefits. Therefore, the goal of drug product development should be focused on improving patient compliance by reducing injection-associated pain as well as stable formulation development. This review will suggest the kinds of factors that should be considered to minimize injection pain with regard to formulation, device, and injection procedures focused on SC injections.

  • High power piezoelectric materials are presently being extensively developed for applications such as ultrasonic motors and piezoelectric transformer In this study, the piezoelectric and dielectric properties of $MnO_2$ doped $0.36Pb(Sc_{1/2}Nb_{1/2})O_{3}-0.25Pb(Ni_{1/3}Nb_{2/3})O_{3}-0.39PbTiO_3$ (hereafter PSNNT), which is the morphotropic phase boundary composition of the PSN-PNN-PT system were investigated. $MnO_2$-addition into the $0.36Pb(Sc_{1/2}Nb_{1/2})O_{3}-0.25Pb(Ni_{1/3}Nb_{2/3})O_{3}-0.39PbTiO_3$ composition increases the piezoelectric coefficient up to $k_{p}{\fallingdotseq}$55.6[%] and $Q_{m}{\fallingdotseq}$252. Moreover, $MnO_2$ addition makes tetragonal phase more stable with respect to rhombohedral phase.
