Immobilization of lipase on appropriate solid supports is one way to improve their stability and activity, can be reused for large scale applications. A sample, cost- effective high loading capacity method still challenging.A facile immobilization was developed in this study, by the use polydopamine coated magnetic nanoparticles (PD-MNPs). Under optimal conditions, 73.9% available immobilized PD-MNPs, yielding a as 429 mg/g. Enzyme assays revealed that PD-MNPs displayed enhanced pH thermal...
Plant responses to drought stress require the regulation of transcriptional networks via drought-responsive transcription factors, which mediate a range morphological and physiological changes. AP2/ERF factors are known act as key regulators resistance networks; however, little is about associated molecular mechanisms that give rise specific adaptations. In this study, we functionally characterized rice (Oryza sativa) factor OsERF71, expressed predominantly in root meristem, pericycle,...
The evaluation of the role physicochemical properties in toxicity nanoparticles is important for understanding mechanisms and controlling behavior nanoparticles. surface charge suggested as one key parameters which decide their biological impact. In this study, we synthesized fluorophore-conjugated polystyrene (F-PLNPs), with seven different types functional groups that were all based on an identical core, to evaluate cellular uptake Phagocytic differentiated THP-1 cells or non-phagocytic...
Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental comprising blood vessels nerve tissue, decontaminating residually through biomechanical instrumentation, root obturation using filler material to replace the space was previously composed pulp. Gutta percha (GP) is typically used as material, it malleable, inert, biocompatible. While filling with GP care for endodontic...
Plant organs are generated from meristems throughout development. Patterning and elaboration of organ primordia occur as a result organized cell division expansion, processes that likely to be controlled, in part, by meristem-derived signals. Communication between the meristem lateral is crucial for maintenance patterning, boundaries thought important mediating this communication. Arabidopsis thaliana LATERAL ORGAN FUSION1 (LOF1) encodes MYB-domain transcription factor expressed boundaries....
Detonation nanodiamonds (DNDs) have been widely explored for biomedical applications ranging from cancer therapy to magnetic resonance imaging due several promising properties. These include faceted surfaces that mediate potent drug binding and water coordination resulted in marked enhancements the efficacy safety of delivery imaging. In addition, scalable processing DNDs yields uniform particles. Furthermore, a broad spectrum biocompatibility studies has shown appear be well-tolerated....
Chemoresistance is a prevalent issue that accounts for the vast majority of treatment failure outcomes in metastatic cancer. Among mechanisms resistance markedly decrease efficacy, efflux drug compounds by ATP-binding cassette (ABC) transporter proteins can impair adequate retention cancer cells required therapeutic cytotoxic activity. Of note, ABC transporters are capable effluxing several classes drugs clinical standards, including anthracyclines such as doxorubicin, well anthracenediones...
Mesoporous forms of silica (MS) with different framework structures and pore sizes, including hexagonal MCM-41 (2.4 nm), cubic MCM-48 (1.9 SBA-15 (7.0 nm) mesocellular silicafoam MSU-F (24.8 were examined as functional additives in the preparation poly(methyl methacrylate) (PMMA)/mesoporous nanocomposites made by situemulsion polymerization compression molding. All composites at 5 wt% loadings MS, exhibit improved thermal stability, an elevated glass transition temperature, enhanced storage...
Significance There is a continued need to advance novel nanomedicine platforms into the clinic address treatment challenges in oncology, infection, and regenerative medicine, among other areas. As such, this work demonstrates in-human validation of nanodiamonds through their incorporation gutta percha [nanodiamond-embedded (NDGP)], polymer that repairs root canal sites following tissue disinfection. A randomized, dual-arm clinical trial was implemented, study endpoints included confirmation...
Drought is the most serious problem that impedes crop development and productivity worldwide. Although several studies have documented root architecture adaption for drought tolerance, little known about underlying molecular mechanisms. Our latest study demonstrated overexpression of OsERF71 in rice roots under conditions modifies structure including larger aerenchyma radial growth, thereby, protects plants from stresses. The OsERF71-mediated modifications are caused by combinatory general...
Abstract Background Plant glycine-rich proteins are categorized into several classes based on their protein structures. The RNA binding (GRPs) members of class IV subfamily possessing N-terminus RNA-recognition motifs (RRMs) and proposed to be involved in post-transcriptional regulation its target transcripts. GRPs developmental process cellular stress responses, but the molecular mechanisms underlying these regulations still elusive. Results Here, we report functional characterization rice...
Nanodiamonds have been suggested as biocompatible materials and are suitable for various biomedical applications, but little is known about how to synthesize safer nanodiamonds. Herein, seven different detonation-synthesized nanodiamonds (DNDs) with sequential sp3/sp2 carbon ratios were assembled by controlling the chemical purification parameters role of ratio on toxicity DNDs was investigated. Carbon black nickel oxide nanoparticles used reference particles. The intrinsic reactive oxygen...
