Objective This study was done to evaluate whether perioperative propranolol (ß-blocker) in ovarian cancer patients undergoing debulking surgery reduced tumor growth induced by surgical stress. Methods a prospective randomized single institution analysis. The primary objective compare the changes CA 125 level (changes between preoperation day 2 and postoperative 7). As arm, received low dose of 40 mg/day (4×10 mg) starting two days before mg twice daily for three following surgery. Results...
Summary Timely detection of herbicide resistance at an early stage crop cultivation is essential to help farmers find alternative solutions manage in their fields. In this study, maximum quantum yield PS II [ F v / m = ( – o )/ ] was measured the 4–5 leaf discriminate between herbicide‐resistant and susceptible biotypes Echinochloa species. The differences spp. were consistent with whole‐plant assay based on I 50 (herbicide doses causing a 50% inhibition ) GR reduction plant fresh weight)...
Miscanthus species are tall perennial rhizomatous grasses with C4 photosynthesis originating from East Asia, and they considered as important bioenergy crops for biomass production. In this study, Agrobacterium-mediated transformation system M. sinensis was developed using embryogenic calli derived mature seeds. order to establish a stable system, optimum conditions obtain highly regenerable transformation-competent were investigated, efficiently induced callus induction medium containing 3...
Phytochromes are dimeric pigment proteins with reversible photochromism between red and far-red light-absorbing forms. They photoreceptors that regulate various aspects of plant growth development have been used for biotechnological applications to improve agricultural performance crops. Miscanthus species suggested as one the most promising energy In this paper, Arabidopsis phytochrome B (PHYB) gene was introduced into sinensis using Agrobacterium -mediated transformation method we...
Abstract Growing dedicated bioenergy crops on marginal land can provide beneficial outcomes including biomass production and energy, resource management, ecosystem services. We investigated the effects of harvest timing (peak standing crop [PEAK] or after killing frost [KF]) nitrogen (N) fertilizer rates (0, 56, 112 kg N ha −1 ) yield, nutrient concentrations, removal perennial grasses a wet land. evaluated three monocultures, switchgrass ( Panicum virgatum L., SW), Miscanthus x giganteus...
This paper presents the modeling and design of digital controller for a phase-shifted full-bridge converter (PSFBC) in discrete-time domain. The discretized PSFBC model is first derived then analyzed considering sampling effect system parameters. Based on this model, was directly designed simulation experimental results are provided to verify proposed design.
Echinochloa species is one of the most problematic weed due to its high competitiveness and increasing herbicide resistance. Florpyrauxifen-benzyl, a new auxin herbicide, was recently introduced for management; however, potential risk development resistance in has not been well-investigated. Thus, this study conducted evaluate baseline sensitivity florpyrauxifen-benzyl estimate future development. A total 70 71 accessions crus-galli oryzicola were collected from paddy fields Korea,...
This study was conducted to evaluate the cross‐resistance of acetolactate synthase ( ALS ) inhibitors with different chemistries, specifically azimsulfuron (sulfonylurea), penoxsulam (triazolopyrimidine sulfonanilide) and bispyribac‐sodium (pyrimidinyl thio benzoate), in Echinochloa oryzicola crus‐galli that had been collected South Korea investigate their herbicide resistance mechanism. Both spp. showed belonging above three chemistries. In a whole plant assay herbicides alone,...
The purpose of this paper is to identify features space planning guidelines for elderly care environments from a holistic health perspective. This was undertaken with the expected outcome promoting better understanding environment as resource. major method used content analysis technique that employed physical, psychological, and social criteria. Data were collected through facility administrators using checklist 114 items related spatial planning, developed analyzing design Japan, UK,...
Abstract A 2‐year field experiment was conducted in Daejeon, South Korea, to investigate changes the growth parameters of rice plants during and model yield loss as affected by competition with Leptochloa fusca , Bidens frondosa Ammannia coccinea under transplanted cultivation. Compared B. A. L. significantly reduced number tillers at early stage, resulting more reduction panicles other components such spikelets, ripened grain ratio ultimate later stage. Among components, panicle most...
The complete chloroplast (cp) genomes of two Miscanthus species, M. sinensis and sacchariflorus, were sequenced investigated for genes, genome size variation, polymorphisms. There are 170 genes in both cp genomes, consisting 122 mRNA (84 protein-coding 38 hypothetical genes), 40 tRNA 8 rRNA genes. contains inverted repeat (IR) regions, separated by large single copy (LSC) region small (SSC) region. Indels responsible bp difference species. In addition, we established phylogenetic...
Miscanthus is a promising bioenergy crop due to its high productivity and broad environmental adaptability tropical temperate climates. As important species such as M. sinensis sacchariflorus are native East Asia, implying more diverse genetic resources in this region, study, we collected about 300 accessions from mainly Korea. From the whole collections, 66 representing geographical location latitude were selected tested through 3-year field trial investigate diversity their agronomic...

Quantifying herbicide dose–response resistance in Echinochloa spp. by measuring root length growth pouches. Can. Plant Sci. 95: 1181–1192. The aim of the presented study was to develop a bioassay for rapid diagnosis Echinochloa. Pre-germinated seeds were incubated pouches (18 cm×16.5 cm) containing solutions range concentrations. Shoot lengths measured after 6 d incubation. Dose–responses estimated...
Miscanthus × giganteus (Miscanthus) is a warm-season perennial grass grown for bioenergy feedstock production. Nitrogen (N) fertilizer management crucial the sustainability of In our two-year study (2018 and 2019), we investigated role vegetation indices (VIs) in evaluating N fertilization (0 N, 56 112 168 kg ha−1) impacts on biomass yield stand health. The flight campaigns were conducted early, middle, late during summer growing season. Among VIs, mid-summer season NDRE provided best...
Echinochloa species are among the most troublesome weeds in rice cultivation, and grow a broad habitat range Korea. Although various ecotypes of have been collected as germplasm for future studies, it has difficult to classify them due their high level morphological similarity. This study was thus conducted develop investigate phylogenetic relationships between 77 accessions with use 23 simple sequence repeat (SSR) markers 24 traits. Of accessions, including 57 from Korea 5 reference...
Understanding the effects of nitrogen (N) fertilizer on soybean-weed competition is essential for establishing a practical tool N application and weed management. A two-year field experiment was conducted in soybean located Bogatyrka (43.82° N, 131.6° E), Primorsky krai, Russia, to investigate multiple-weed interference (Glycine max) yield model these effects. Soybean loss caused by multiple weeds including common ragweed (Ambrosia artemisiifolia), barnyard grass (Echinochloa crus-galli),...
