The B3 domain protein LEAFY COTYLEDON2 (LEC2) is required for several aspects of embryogenesis, including the maturation phase, and is sufficient to induce somatic embryo development in vegetative cells. Here, we demonstrate that LEC2 directly controls a transcriptional program involved in the maturation phase of seed development. Induction of LEC2 activity(More)
Nucleotide-binding site (NBS)-encoding resistance genes are key plant disease-resistance genes and are abundant in plant genomes, comprising up to 2% of all genes. The availability of genome sequences from several plant models enables the identification and cloning of NBS-encoding genes from closely related species based on a comparative genomics approach.(More)
Single nucleotide polymorphisms (SNPs) and/or insertion/deletions (InDels) are frequent sequence variations in the plant genome, which can be developed as molecular markers for genetic studies on crop improvement. The ongoing Brassica rapa genome sequencing project has generated vast amounts of sequence data useful in genetic research. Here, we report a(More)
OBJECTIVES To evaluate the effect of exenatide on gastric emptying (GE) in type 2 diabetes using scintigraphy. METHODS Seventeen subjects with type 2 diabetes participated in a randomized, single-blind, 3-period, crossover study. In each 5-day period, 5 or 10 microg exenatide or placebo was administered subcutaneously BID. Oral antidiabetic treatments(More)
AIMS To evaluate the pharmacokinetics (PK), safety and tolerability of a single exenatide dose in patients with renal impairment (RI). METHODS Exenatide (5 or 10 microg) was injected subcutaneously in 31 subjects (one with Type 2 diabetes) stratified by renal function [Cockcroft-Gault creatinine clearance (CrCL), number of subjects]: normal (>80 ml(More)
Plant somatic cells have the remarkable ability to regenerate an entire organism. Many species in the genus Kalanchoë, known as "mother of thousands," develop plantlets on the leaf margins. Using key regulators of organogenesis (STM) and embryogenesis (LEC1 and FUS3) processes, we analyzed asexual reproduction in Kalanchoë leaves. Suppression of STM(More)
Embryogenesis in higher plants consists of two major phases, morphogenesis and maturation. Morphogenesis involves the establishment of the embryo's body plan, whereas maturation involves cell expansion and accumulation of storage macromolecules to prepare for desiccation, germination and early seedling growth. Arabidopsis mutants showing defects in(More)
This study focused on the preparation of resveratrol nanocarrier systems and the evaluation of their in vitro antibacterial activities. Gold nanoparticles (AuNPs) and silver nanoparticles (AgNPs) for resveratrol nanocarrier systems were synthesized using green synthetic routes. During the synthesis steps, resveratrol was utilized as a reducing agent to(More)
Exenatide, a treatment for type 2 diabetes, slows gastric emptying as part of its pharmacologic action and may alter the absorption of concomitant oral drugs. This open-label, 2-period, fixed-sequence study evaluated the influence of exenatide coadministration on the pharmacokinetics and pharmacodynamics of warfarin, a narrow therapeutic index drug, in(More)
This open-label study investigated the effect of exenatide coadministration on the steady-state plasma pharmacokinetics of digoxin. A total of 21 healthy male subjects received digoxin (day 1, 0.5 mg twice daily; days 2-12, 0.25 mg once daily) and exenatide (days 8-12, 10 microg twice daily). Digoxin plasma and urine concentrations were measured on days 7(More)
