Conclusions The results of this study highlight that opioid tapering is challenging and may be influenced by many different factors. Some patients find opioid tapering particularly difficult and therefore need additional assistance in order to taper off successfully. Implications For opioid tapering to succeed, it is highly important to establish a trustful relationship with the patients, to take each patient's personal circumstances into account and to address fears of increased pain and withdrawal symptoms. Clinicians should also focus on patient involvement in opioid tapering and consider to offer a follow-up after discharge to patients at risk for prolonged opioid use.Bacteriocins produced by lactic acid bacteria are safer alternatives to the more popularly used chemical preservatives which exhibit several adverse effects. The bacteriocins have an advantage of being efficient in controlling food pathogens without possessing any side-effects. However, the bacteriocins have a limitation of exhibiting a narrow antimicrobial spectrum and having a high-dosage requirement. With an aim to combat these limitations, the present study involved the biosynthesis of bacteriocin-capped nanoparticles, using two bacteriocins (Bac4463 and Bac22) extracted and purified from Lactobacillus strains. Nanoconjugates synthesised at optimum conditions were characterized using various physico-chemical techniques. The interaction of bacteriocin-capped silver nanoparticles with the pathogenic bacteria was observed using scanning electron microscopy, wherein the deformed and elongated cells were clearly visible. In vitro antimicrobial efficacy of both Bac4463-capped silver nanoparticles and Bac22-capped silver nanoparticles against different food pathogens was observed to be enhanced in comparison to the antimicrobial activity of bacteriocins alone. Minimum inhibitory concentration was observed to be as low as 8 μg/ml for Bac4463-capped silver nanoparticles against Staphylococcus aureus, and 2 μg/ml for Bac22-capped silver nanoparticles against Shigella flexneri. This study, therefore, recommends the use of bacteriocin-capped nanoparticles as food preservatives to control the growth of food spoiling bacteria.In order to expand the application in the medical field and enhance pharmacological effects, casein-myricetin nanomicelles were prepared by the self-assembly method and characterised by ultraviolet-visible spectroscopy and Fourier transform infrared spectroscopy. The parameters in self-assembly were optimised according to the factors of particle size, encapsulation yield, and drug loading. The result showed a pH of 5.5, a casein concentration of 2 mg/ml, a mass ratio of casein to myricetin of 81, ultrasonic power of 300 W, ultrasonic time of 5 min and ethanol volume of 7 ml were the optimal conditions. read more The situ cycle intestinal perfusion methods indicated that casein-myricetin nanomicelles can be more easily absorbed by small intestine than myricetin standard sample. Therefore, casein micelles are effective for improving the water solubility of myricetin.Biosynthesis of silver nanoparticles (AgNPs) using plant extract is a cheap, easily accessible and natural process in which the phyto-constituents of the plants act as capping, stabilising and reducing agent. The present study explored the biosynthesis of AgNPs using aqueous leaf extract of Tinospora cordifolia and characterised via various techniques such as Fourier transform infrared, scanning electron microscopy, transmission electron microscopy (TEM), energy dispersive X-ray analysis and X-ray diffraction. Here, TEM confirmed the spherical morphology with 25-50 nm size of synthesised AgNPs. Further, anticancer efficiency of AgNPs synthesised using T. cordifolia leaves were evaluated against human lung adenocarcinoma cell line A549 by MTT, trypan blue assay, apoptotic morphological changes using Annexin V-FITC and Propidium iodide (PI), nuclear morphological changes by DAPI (4, 6-diamidino-2-phenylindole dihydrochloride) staining, reactive oxygen species generation and mitochondrial membrane potential determination. Results confirmed the AgNPs synthesised using T. cordifolia leaves are found to be highly toxic against human lung adenocarcinoma cell line A549.Gold nanoparticles (AuNPs) possess colourful light-scattering properties due to different composition, size and shape. Their unique physical, optical and chemical properties coupled with advantages, have increased the scope of anisotropic AuNPs in various fields. This study reports a green methodology developed for the synthesis of anisotropic AuNPs. The aqueous extracts of Alternanthera sessilis (PGK), Portulaca oleracea (PAK) and Sterculia foetida (SF) with gold ions produced violet, purple and pink coloured AuNPs, respectively, under sonication and room temperature methods revealing the formation of different shapes of AuNPs. The results of TEM analysis of AuNPs confirmed the formation of triangular plate AuNPs of the size 35 nm for PAK extract. Spherical-shaped AuNPs (10-20 nm) were obtained using an extract of PGK. SF extract produced rod, hexagon, pentagon-shaped AuNPs and nanorice gold particles. The cell viability studies of the PGK, PAK and SF-mediated AuNPs on MCF-7 cell lines by MTT assay revealed the cytotoxic activity of AuNPs to depend on the size, shape and the nature of capping agents. The synthesised AuNPs significantly inhibited the growth of cancer cells (MCF-7) in a concentration-dependent manner. The size and shape of these anisotropic AuNPs also reveal its potency to be used as sensors, catalysis, photothermal and therapeutic agents.This study is planned to synthesise new biocompatible, nano antimicrobial formulation against biofilm producing strains. Aqueous root extract of Arctium lappa l. was used to synthesise ceria nanoparticles (CeO2-NPs). The synthesised nanoparticles were encapsulated with nano-chitosan by sol-gel method and characterised using standard techniques. Gas chromatography-mass spectrometer of Arctium lappa l. revealed the presence of ethanol, acetone, 1- propanol, 2-methylethane, 1,1-di-ethoxy, 1-Butanol, and oleic acid acted as reducing and surface stabilising agents for tailoring morphology of CeO2-NPs. Erythrocyte integrity after treatment with synthesised nanomaterials was evaluated by spectrophotometer measurement of haemoglobin release having biocompatibility. Scanning electron microscopy revealed the formation of mono dispersed beads shaped particles with mean particle size of 26.2 nm. X-ray diffractometry revealed cubic crystalline structure having size of 28.0 nm. After encapsulation by nano-chitosan, the size of CeO2-NPs enhances to 48.
