This study examines the shared caregiving responsibilities of adult children in the form of long-existing practice of meal and residence rotation of elderly parents in rural China in the post-reform era. Based on the analysis of qualitative data collected in two northern Chinese villages in 2007, the study goes beyond the usual focus on inter-generational(More)
Chloroplast transformation in wheat was achieved by bombardment of scutella from immature embryos and immature inflorescences, respectively. A wheat chloroplast site-specific expression vector, pBAGNRK, was constructed by placing an expression cassette containing neomycin phosphotransferase II (nptII) and green fluorescent protein (gfp) as selection and(More)
The high molecular weight glutenin subunit (HMW-GS) compositions of 66 Chinese endemic wheats were determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Ten alleles at the Glu-1 loci were detected in 50 Tibetan weedrace wheat accessions which in combination resulted in seven different HMW-GS patterns. Four HMW-GS patterns were(More)
Increasing the provitamin A content in staple crops via carotenoid metabolic engineering is one way to address vitamin A deficiency. In this work a combination of methods was applied to specifically increase β-carotene content in wheat by metabolic engineering. Endosperm-specific silencing of the carotenoid hydroxylase gene (TaHYD) increased β-carotene(More)
Immature embryos have been used frequently as target tissues in the genetical transformation of wheat. However, obtaining a large number of high quality immature embryos throughout the year is a laborious and delicate process, because of the need to cultivate the plants under controlled conditions. To circumvent this, we have employed mature embryos rather(More)
To identify inhibitors of the intrinsic N-acetylated alpha-linked acidic dipeptidase (NAALADase) activity of prostate specific membrane antigen (PSMA) that may be useful for targeting imaging agents or chemotherapeutic drugs to disseminated prostate cancer, analogs of the tetrahedral transition state for hydrolysis of the natural substrate,(More)
Seed storage proteins in wheat endosperm, particularly high-molecular-weight glutenin subunits (HMW-GS), are primary determinants of dough properties, and affect both end-use quality and grain utilization of wheat (Triticum aestivum L). In order to investigate the interactive effects between the transgenically overexpressed 1Ax1 subunit with different(More)
Although propofol is most commonly known for its general anesthetic properties, at subanesthetic doses, propofol has been effectively used to suppress seizures during refractory status epilepticus, a mechanism, in part, attributed to the inhibition of neuronal sodium channels. In this study, we have designed and synthesized two novel analogs of propofol,(More)
Room-temperature sodium-ion batteries have shown great promise in large-scale energy storage applications for renewable energy and smart grid because of the abundant sodium resources and low cost. Although many interesting positive electrode materials with acceptable performance have been proposed, suitable negative electrode materials have not been(More)
Regenerable, embryogenic haploid cell suspensions were initiated and established from type II pollen calluses of two selected Chinese maize genotypes (No 592 Y and 592.A2 LY). The induction frequency of friable, embryogenic callus (type II) was highly dependent on three factors: genotype, medium, cold pretreatment, and on their interactions. Repeated callus(More)
