The UV-Vis spectroscopy was used to study cisP loading and release from the prepared nanocomposites. The results showed that the highest loading efficacy was achieved by CS/M and CS/M/S/GO nanocomposites (87% and 84% respectively). While the releasing potentiality for CS/M composite was the highest compared with the other ones (91%). Polysaccharide is the main active compound of Lilium, and showed many activities, such as hypoglycemic, antioxidant, immune-modulatory. There are three types' Lilium in China market, i.e. Lilium lancifolium Thunb (JD), Lilium davidiivar. Unicolor Salisb (L. davidii var)(LZBH), and Lilium brownii F.E. Brown var. viridulum Baker (BH). Near infrared spectroscopy (NIR) technique has become popular in the fields of quality control, due to its advantages, such as fast, non-destructive, and can detect several ingredients, simultaneously. In this study, a classification model was established based on NIR technique and random forest method to accurately distinguish three types' Lilium species, and the classification accuracy reached 94.37%. Furthermore, taking the effects of neighbor wavelength into account, a new weighted partial least square algorithm was proposed to establish an accurate and quantitative model for predicting the polysaccharide contents of these samples. In the model establishing process, some signal pre-treatment methods were optimized, and the validation results with highest determination coefficient (R2) and low root mean square errors of prediction (RMSEP) were, 0.9455 and 0.9098, respectively. The obtained results showed that combined NIR technique with chemometrics was an effective and green method for quality control. V.A polymer-clay hybrid composite material, (KG-g-PMETAC/MMT) has been synthesised by microwave assisted free radical polymerisation using modified karaya gum and clay mineral and was characterised by various techniques. The karaya gum has been modified by grafting with (2-methacryloyloxy ethyl) trimethyl ammonium chloride prior to making the clay composite. Montmorillonite was used as the clay component. The nanocomposite exhibited pH responsive swelling behaviour. The maximum swelling of 42.23 g/g was observed at pH 7.0 and minimum of 17.28 g/g was noticed at pH 9.2. The water transport mechanism was Fickian in nature and followed second order kinetic model. The adsorption capacities of the nanocomposite for the chosen cationic dyes, methylene blue (MB), toluidine blue (TB), crystal violet (CV) and azure B (AB) were found to 155.85, 149.64, 137.77 and 128.78 mg/g respectively. The dye adsorption was found to be a pseudo-first order kinetic process. The adsorption data is found to best fit with Freundlich isotherm model indicating heterogeneous adsorption and possibility of multilayer formation. BIBF 1120 mw Negative value of ΔG indicated the spontaneous nature of adsorption process at the temperatures under study. The reusability studies indicated that desorption of about 70% of the adsorbed dyes can be achieved after two consecutive cycles. V.In a world that canopies numerous opportunities to advance towards a green sustainable life, biopolymer development offers a platform that fits into the paradigm of achieving an eco-friendly environment whilst reducing reliance on the scarce fossil fuel elements for the fabrication of day-to-day products. Today's technological improvements have aided biopolymer end-products to escalate to higher purposes and soon may have their performance level in par with the petroleum-based synthetic polymers. The motive of this paper is to shimmer light on some aspects of biopolymers that include its classes, properties, composites and applications. Depending on the type of class on the basis of various categories, many enthralling chemistries of polymer composition can be substantiated. Essential properties can imparted to the ensuing biopolymer by altering its chemical configuration and method of synthesis while also focusing on its functional purpose. Nowadays, biopolymer composites blend qualities of one biopolymer with another to acquire an enhanced component that showcases unique explicit attributes. There are several techniques to process biopolymer composites, of which in-situ, infiltration and electrospinning methods have captured considerable limelight. Biopolymers and its composites have embarked captivating impressions in regions of biomedical, packaging, agricultural and automotive applications. Although their efficacy is yet to reach their fossil fuel counterparts, biopolymers have laid a distinguishing mark that will continue to inspire creation of novel substances for many years to come. In this study, iron oxide (γFe2O3) nanoparticles synthesized via hydrothermal route and doxorubicin (Dox) were successfully encapsulated into natural almond gum hydrocolloids via antisolvent precipitation technique. Cubic γFe2O3 crystal structure of the synthesized iron oxide nanoparticles were confirmed using X-ray diffraction and X-ray photoelectron spectroscopy. The refinement of XRD and elemental analysis revealed oxygen vacancies, which is also indicated by an increased magnetization comparable to bulk γFe2O3. Magnetization studies revealed the superparamagnetic nature of IO and IODPC nanoparticles. The particles were characterized for its morphology (TEM and FESEM), size (FESEM, DLS), surface charge (DLS) and MRI (proton relaxation). The heating ability of the IO and IODPC nanoparticles was studied and their specific absorption rate was found to be 83.06 W/g and 154.37 W/g respectively. The entrapment efficiency of the IODPC nanoparticles was found to be 88.29%. The drug release studies revealed that IODPC nanoparticles were more responsive towards acidic pH and their release follows Higuchi diffusion kinetics. In-vitro uptake and in-vitro cell viability studies were performed for IODPC nanoparticles using HeLA cell lines. The inhibiting effect of chitosan coating (2%) on the softening and sodium carbonate-soluble pectin (SSP) evolution of sweet cherries during non-isothermal storage was investigated. Chitosan coating significantly extend the softening (6.4% greater than the control group), maintained the SSP content (6.6% greater than the control group), and reduced the degradation of SSP by inhibiting the expression of the paPME1-5 genes, which regulating pectin methylesterase activity of sweet cherries under temperature variation. In addition, the results of methylation and monosaccharide composition indicated that the chitosan coating reduced demethylation of SSP and the loss of RG-I main and side chain neutral sugars. Atomic force microscopy images revealed that the coated sweet cherries contained more linked, branched, and long SSP chains and maintained the width of the pectin backbone (>140 nm). These results indicated that a chitosan coating is feasible to preserve postharvest fruit under non-isothermal conditions. Pulmonary fibrosis is a serious respiratory disease, with limited therapeutic options. Since TGF-β is a critical factor in the fibrotic process, downregulation of this cytokine has been considered a potential approach for disease treatment. Herein, we designed a new lung-targeted delivery technology based on the complexation of polymeric antisense oligonucleotides (pASO) and dimeric human β-defensin 23 (DhBD23). Antisense oligonucleotides targeting TGF-β mRNA were polymerized by rolling circle amplification and complexed with DhBD23. After complexation with DhBD23, pASO showed improved serum stability and enhanced uptake by fibroblasts in vitro and lung-specific accumulation upon intravenous injection in vivo. The pASO/DhBD23 complex delivered into the lung downregulated target mRNA, and subsequently alleviated lung fibrosis in mice, as demonstrated by western blotting, quantitative reverse-transcriptase PCR (qRT-PCR), immunohistochemistry, and immunofluorescence imaging. link2 Moreover, as the complex was prepared only with highly biocompatible materials such as DNA and human-derived peptides, no systemic toxicity was observed in major organs. Therefore, the pASO/DhBD23 complex is a promising gene therapy platform with lung-targeting ability to treat various pulmonary diseases, including pulmonary fibrosis, with low side effects. CdTe quantum dots (QDs) are still widely considered as excellent fluorescent probes because of their far more superior optical performance and fluorescence efficiency than non‑cadmium QDs. link3 Thus, it is important to find ways to control their toxicity. In this study, CdTe QDs and CdTe@ZnS QDs both could cause IL-1ß-mediated inflammation following with pyroptosis in BV2 cells, but the toxic effects caused by CdTe@ZnS QDs was weaker than CdTe QDs, which demonstrated the partial protection of ZnS shell. When investigating the molecular mechanisms of QDs causing the inflammatory injury, the findings suggested that cadmium-containing QDs exposure activated NF-κB that participated in the NLRP3 inflammasome priming and pro-IL-1ß expression. After that, QDs-induced excessive ROS generation triggered the NLRP3 inflammasome activation and resulted in active caspase-1 to process pro-IL-1ß into mature IL-1ß release and inflammatory cell death, i.e. pyroptosis. Fortunately, the inhibitions of caspase-1, NF-κB and ROS or knocking down of NLRP3 all effectively attenuated the increases in the IL-1ß secretion and cell death caused by QDs in BV2 cells. This study provided two methods to alleviate the toxicity of cadmium-containing QDs, in which one is to encapsulate bare-core QDs with a shell and the other is to inhibit their toxic pathways. Since the latter way is more effective than the former one, it is significant to evaluate QDs through a mechanism-based risk assessment to identify controllable toxic targets. BACKGROUND Cough is one of the most common presenting symptoms to general practitioners. The objective of this article is to collate the pediatric components of the CHEST chronic cough guidelines that have recently updated the 2006 guidelines to assist general and specialist medical practitioners in the evaluation and management of children who present with chronic cough. METHODS We reviewed all current CHEST Expert Cough Panel's statements and extracted recommendations and suggestions relating to children aged ≤14-years with chronic cough (>4-weeks duration). Additionally, we undertook systematic reviews to update other sections we considered relevant and important. RESULTS The 8 recent CHEST guidelines relevant to children, based on systematic reviews, reported some high-quality evidence in the management of chronic cough in children (e.g. use of algorithms and management of wet/productive cough using appropriate antibiotics). However, much evidence is still inadequate particularly in the management of non-specific cough in the community. CONCLUSION The recommendations and suggestions related to the management of chronic cough in the pediatric age group have been based upon high quality systematic reviews and are summarized in this article. Compared to the 2006 Cough Guidelines, there is now high-quality evidence for some aspects of the management of chronic cough in children. However, further studies particularly in primary healthcare are required.
