Abstract Posidonia Oceanica waste was used as reinforcement in a polyethylene matrix and the obtained composites were characterised by a tensile test and morphological analysis. The fi brous material derived from P. Oceanica wastes was characterised by morphological, thermal and chemical analysis, and a subsequent treatment with sodium hydroxide (NaOH) at different weight content (2, 5 and 10 wt%) was considered as an optimised method for surface modifi cation of pristine fi bres (PO). The TGA analysis and morphological investigation of the treated fi bres selected the 5 wt% of NaOH as the best treatment. Matrix compatibilisation with maleic anhydride grafted… More >

Abstract In the work presented in this article surface chemical modifi cation was applied to ramie cellulose nanocrystals by grafting organic acid chlorides presenting different lengths of the aliphatic chain. The objective of this surface chemical treatment was to enhance the nonpolar nature of the grafted nanocrystals and improve their dispersibility in a nonpolar polymeric matrix. The occurrence of the chemical modifi cation was evaluated by Fourier transform infrared (FTIR) spectroscopy, the degree of crystallinity by X-ray diffraction, and the morphology by scanning electron microscopy with fi eld emission gun (FEG-SEM) and atomic force microscopy (AFM). The morphology and crystallinity provided… More >

Abstract In this work, we report a one-pot synthesis of amphiphilic miktoarm cellulose graft copolymers, cellulose (-graft-oligo(L-lactide))-graft-oligo(N-isopropylacrylamide) (Cell(-g-OLLA)-g-ONIPAM), with dual side chains of oligo(L-lactide) and oligo(N-isopropylacrylamide) using 2-bromoisobutyl bromide functionalized cellulose (Cell(-OH)-Br) as the macroinitiator, by simultaneously conducting ring-opening polymerization and atom transfer radical polymerization using Cu/CuBr/PMDETA/Sn(Oct)₂ as the catalytic system. The chemical structures and thermal properties of Cell(-g-OLLA)-g-ONIPAMs were characterized with ¹ H and ¹³C nuclear magnetic resonance spectroscopy, differential scanning calorimetry and thermal gravimetric analysis. Cell (-g-OLLA)-g-ONIPAM could self-assemble into micelles in the aqueous solution as confi rmed by environmental scanning electron microscopy and dynamic light scattering analyses. The… More >

Abstract Relatively poor in vitro rooting has limited the large-scale commercial production of tree peony. In this study, on the basis of transcriptome sequencing, differentially expressed genes and the associated metabolic pathways were identified in tree peony roots at different stages of root formation under sandy loam cultivation. A total of 31.63 Gb raw data were generated and 120,188 unigenes (mean length of 911.98 bp) were annotated according to six databases (NR, NT, GO, KEGG, COG, and Swiss-Prot). Analyses of the ungerminated root primordium period, induced root primordium period, and root formation period detected 8,232, 6,907, and 10,687 differentially expressed genes related… More >

Abstract Microfibrillated cellulose (MFC) is often added to polylactic acid (PLA) matrixes as a reinforcing filler to obtain fully-biodegradable composites with improved mechanical properties. However, the incompatibility between MFC and the PLA matrix limits the mechanical performance of MFC-reinforced PLA composites. In this paper, DL-lactic acid-grafted-MFC (MFC-g-DL) was used to improve the compatibility with PLA. Reinforced composites were prepared by melt extrusion and hot-cold pressing. The tensile strength of the PLA/MFC-g-DL composite increased by 22.1% compared with that of PLA after adding 1% MFC-g-DL. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and dynamic thermomechanical analysis (DMA) were used to explore… More > Graphic Abstract

Abstract Baicalein, an active ingredient separated from Astragalus membranaceus, has shown its anticancer ability in various cancers. However, its effect on nasopharyngeal carcinoma has not been explored yet. The present study aimed to investigate the effect of baicalein on the growth, proliferation, apoptosis, and cell cycle of human nasopharyngeal carcinoma cells, as well as transplanted nude mouse xenograft. The results showed that baicalein inhibited the growth and proliferation of CNE1 and CNE2 cells in a time- and concentration-dependent manner. It also caused a significant increase in the number of cells in the G₀/G₁ phase and a decrease in the G₂/M phase,… More >

Abstract Adder with high efficiency and accuracy is the major requirement for electronic circuit design. Here the optical logic gate based adder circuit is designed for better performance analysis of optical input signals varied with the wavelength. Efficiency of the adder can be improved by increasing the speed of operation, reducing the complexity and power consumption. To maintain the high efficiency with accuracy, a new combination of adder has been proposed and tested in this work. A new adder by combining the logics of Brent Kung, Sklansky and Kogge Stone adders by Tree Grafting Technique (BSKTGT) has been tested along with… More >

Abstract Pulmonary valve implant is frequently necessary in children and adults with congenital heart disease. Infective endocarditis represents a rare but life-threatening complication after transcatheter pulmonary valve implantation. There are various treatments for native or prosthetic valve endocarditis. Surgical intervention, combined with intravenous antibiotic treatment, is of paramount importance, in case of concomitant mediastinal infection, in order to ensure the radical debridement of all infected tissue, avoiding any recurrent endocarditis. In this report, we describe a rare case of mediastinitis, associated with an infected endocarditis, occurring 8 months after Melody (Medtronic^®, Minneapolis, USA) valve implant, successfully treated with the implantation of… More >

Abstract This review aims to offer a vision of the clinical reality of cell therapy today in intensive medicine. For this, it has been carried out a description of the properties, functions, and Mesenchymal Stem Cells (MSCS) sources to subsequently address the evidence in preclinical models and studies clinical trials with whole cells and models attributed to small extracellular vesicles (sEVs), nanoparticles made up of microvesicles secreted by cells with an effect on the extracellular matrix, and their impact as an alternative towards cell-free regenerative medicine. MSCs are cells that enhance the regenerative capacity which can be differentiated typically in different… More >

Abstract Bone grafting is a surgical restructuring procedure of replacing broken bones and reconstructing missing bone pieces so that complex bone fractures can be repaired to avoid any serious health risk as well as permanent bone disfiguration. Normally, human bones tend to regenerate and heal completely from fracture. But it needs a small scaffold to provide the necessary space to grow. Bone implants allow a broken bone to grow seamlessly. Traditionally, non-corrosive metal alloys are used for fixing broken bones. A metal plate is fastened between two ends of broken bones to join them. However, issues like high weight, high cost,… More >
