To successfully induce tissue repair or regeneration in vivo, bioengineered constructs must possess both optimal bioactivity and mechanical strength. This is because cell interaction with the extracellular matrix (ECM) produces two different but concurrent signaling mechanisms: ligation-induced signaling, which depends on ECM biological stimuli, and(More)
In the present study, we used suspension cultured cells from Chorispora bungeana Fisch. and C.A. Mey to investigate whether nitric oxide (NO) is involved in the signaling pathway of chilling adaptive responses. Low temperatures at 4 °C or 0 °C induced ion leakage, lipid peroxidation and cell viability suppression, which were dramatically alleviated by(More)
It is true that we have a global fisheries crisis, but it is equally true that we already have the tools to understand its causes and overcome it. One of the elements of this toolkit is the Food and Agriculture Organization (UN) Code of Conduct for Responsible Fisheries, launched in 1995 and endorsed by all of FAO's member states. The Code, a mixture of(More)
The objective of this study was to investigate whether abscisic acid (ABA), a second messenger in chilling stress responses, is involved in brassinosteroids (BRs)-induced chilling tolerance in suspension cultured cells from Chorispora bungeana. The suspension cells were treated with 24-epibrassinolide (EBR), ABA, ABA biosynthesis inhibitor fluridone (Flu)(More)
Polygalacturonase-inhibiting proteins (PGIPs) are plant defense proteins. To date, no spatial distribution of PGIPs and interaction between PGIPs and nitric oxide (NO) in plant were described. Here, we first reported the full-length cDNA sequence of PGIP of Chorispora bungeana (CbPGIP1). Notably, immunofluorescence localization showed that the CbPGIP was(More)

We developed an ultrasensitive fluorescence resonance energy transfer (FRET) aptasensor for kanamycin detection, using upconversion nanoparticles (UCNPs) as the energy donor and graphene as the energy acceptor. Oleic acid modified upconversion nanoparticles were synthesized through a hydrothermal process followed by a ligand exchange with hexanedioic acid.(More)
To develop a growing root, cell division in the root meristem has to be properly regulated in order to generate or propagate new cells. How cell division is regulated in the root meristem remains largely unknown. Here, we report the identification and characterization of the Arabidopsis (Arabidopsis thaliana) RETARDED ROOT GROWTH (RRG) gene that plays a(More)
Postoperative cognitive dysfunction (POCD) is a common geriatric complication, although its exact neuropathogenesis remains elusive. Blockers of the renin-angiotensin system (RAS) ameliorate cognitive deficits in inflammatory brain disorders, with its effects on POCD not yet fully elucidated. The aim of the present study was to investigate regulation of the(More)
The underlying mechanism of isoflurane-induced cognitive dysfunction in older individuals is unknown. In this study, the effects of isoflurane exposure on the hippocampal blood-brain barrier (BBB) in aged rats were investigated because it was previously shown that BBB disruption involves in cognitive dysfunction. Twenty-month-old rats randomly received 1.5%(More)
