Bacteriocins sourced from traditional fermented foods for ensuring food safety: the microbial guards
Authors: Bisht Vishakha , Das Biki , Navani Naveen Kumar 
Published: August 2024

AbstractConcerns about food safety have consistently driven the exploration of potent antimicrobials with probiotic origins. Identification of probiotic‐derived bacteriocins as robust alternatives to antibiotics has gained traction following the COVID‐19 pandemic. Additionally, the global market is witnessing an increasing preference for minimally processed food products free from chemical additives. Another contributing factor to the search for potent antimicrobials is the escalating number of infections caused by antibiotic‐resistant bacteria and the need to mitigate the significant damage inflicted on the commensal human microbiota by broad‐spectrum antibiotics. As an alternative bio‐preservation strategy, there is substantial enthusiasm for the use of bacteriocins or starter cultures producing bacteriocins in preserving a variety of food items. This review specifically focuses on bacteriocins originating from lactic acid bacteria associated with fermented foods and explores their technological applications as nanobiotics. The food‐grade antibiotic alternatives, whether utilized independently or in combination with other antimicrobials and administered directly or encapsulated, are anticipated to possess qualities of safety, stability and non‐toxicity suitable for application in the food sector. © 2024 Society of Chemical Industry.

Authors: Keceli Turkan Mutlu , Mertoglu Tuba Simsek 
Published: August 2024

AbstractBackgroundThe use of natural antioxidants and antimicrobials in dairy production can increase the variety of dairy‐based products. In this study, the antioxidant and antimicrobial changes in lactic butter samples made from heat‐treated creams and enriched with M. communis essential oils (EOs) were investigated.ResultsThe best lactic butter properties were achieved by optimizing the process at 70 and 80 °C. M. communis EOs decreased lipid oxidation and spoilage microorganism growth in lactic butter during cold storage. M. communis EOs have antioxidant and antimicrobial activity in lactic butter equal to that of ascorbyl palmitate. α‐Pinene, p‐cymene, limonene, 3‐carene, 1,8‐cineol, β‐linalool, α‐terpineol and myretenol are the major contributors to the antioxidant and antimicrobial activities of M. communis EOs. They exhibit antioxidant activity by neutralizing free radicals by donating hydrogen or acting as termination enhancers, and antimicrobial activity by disruption of cell membranes, which may result in the leakage of macromolecules or the loss of essential metabolites, ultimately leading to cell death during the storage of lactic butter samples.ConclusionThe addition of M. communis EOs improves lactic butter stability equal to that of ascorbyl palmitate, and may be applied as a natural and effective preservative to maintain butter from lipid oxidation and microbial spoilage and enhance its safety.Practical applicationsThe growing recognition of the health benefits of natural antioxidants, as opposed to synthetic ones, has led to the development of new applications for natural antioxidants. In this regard, M. communis L. EOs can be used to enhance the shelf stability of cold‐stored lactic butter. © 2024 The Author(s).

Sustainable development of non‐mega international sports events in a small town: Social impacts, residents' attitudes, and leveraging role of local government
Authors: Wang Xi , Qiao Guiqiang , Lu Yu 
Published: August 2024

AbstractThe impacts of mega international sports events on host communities have attracted considerable scholarly attention, while few studies explored the impacts of non‐mega international sports events (NMISEs). Prior studies focus on economic impacts of hosting sports events, ignoring social impacts. This study interrogates the dynamics behind staging NMISEs in the small town of Cambridge, New Zealand, focusing on social impacts. It also examines the role of social exchange theory in explaining formation of residents' attitudes toward NMISEs. As findings indicate, Cambridge residents are supportive of NMISEs. They believe that hosting the events improves wellbeing. The local authority plays an important role in event planning and management. It was found that complementarity of social exchange theory and community attachment helps explain the phenomenon.

Published: August 2024

AbstractResidents' educational expectations for the next generation are closely related to individuals' awareness‐raising and community development, reflecting the sustainability of tourism development. However, few studies have focused on the formation of parental educational expectations (PEE) for their children during the process of residents' tourism participation. To fill this gap, this study examines the impact of resident participation on PEE using a three‐dimensional framework for resident participation that incorporates the decision‐making, economic, and social dimensions. A binary logistic regression was employed to analyze the survey data from 473 residents in Jiuzhai Valley, China. The results indicate that social participation is the strongest facilitator for PEE. Economic participation exerts a negative effect on PEE, whereas decision‐making participation has a positive but insignificant effect. This study holds implications for local authorities managing tourism destinations regarding improving the efficiency of residents' participatory behaviors and human capital accumulation in developing countries.
Value through diversity: A systematic literature review to understand diversity and inclusion in consumer research
Authors: Branca Generoso , Grosso Monica , Castaldo Sandro 
Published: August 2024

AbstractEmbracing diversity and promoting inclusion is a critical challenge for marketers to meet the diverse consumers' needs and have a positive social impact. Despite increasing attention to diversity and inclusion, and calls to address inequalities, there appears to be a lack of a thorough understanding of diversity and inclusion in consumer research, and how marketing can effectively contribute to an inclusive and equity‐oriented society. Previous reviews and conceptual articles often focus on specific types of diversity or contexts. This study aims to provide a comprehensive examination of diversity and inclusion in consumer research through a systematic literature review of 52 articles combined with the theory, context, characteristics, and methodology (TCCM) framework. Our findings highlight that companies can actively foster inclusion and enhance equity through their policies, also by addressing stigmatization and marginalization. A conceptual framework outlines the impacts of these policies on individuals, society, and company performances, followed by a detailed research agenda for future studies. This article emphasizes the role of marketing in fostering inclusion but also stimulates practitioners to contribute through policies beyond representation and advertising, such as service and product design, and ensuring vulnerable consumers access to resources.
Degradation strategies for structural characterization of insoluble synthetic polymers by mass spectrometry
Authors: Fouquet Thierry N. J. , Cody Robert B. , Charles Laurence 
Published: August 2024

AbstractWith the advent of soft ionization techniques such as electrospray (ESI) and matrix‐assisted laser desorption/ionization (MALDI) to produce intact gas‐phase ions from nonvolatile macromolecules, mass spectrometry has become an essential technique in the field of polymeric materials. However, (co)polymers of very high molecular weight or with reticulated architectures still escape ESI or MALDI, mainly due to solubility issues. Strategies developed to tackle such an analytical challenge all rely on sample degradation to produce low‐mass species amenable to existing ionization methods. Yet, chain degradation needs to be partial and controlled to generate sufficiently large species that still contain topological or architectural information. The present article reviews the different analytical degradation strategies implemented to perform mass spectrometry of these challenging synthetic polymers, covering thermal degradation approaches in sources developed in the 2000s, off‐line sample pre‐treatments for controlled chemical degradation of polymeric substrates, and most recent achievements employing reactive ionization modes to perform chemolysis on‐line with MS.

AbstractBackgroundVibrotactile stimulation has been studied in its efficacy of reducing freezing of gait (FOG) in patients with Parkinson's disease (PD). However, the results are still controversial. We evaluated the efficacy of a newly developed vibrotactile foot device on freezing severity and gait measures in PD patients with FOG.ObjectiveTo evaluate the efficacy of vibrotactile foot device on PD patients with FOG.MethodsThirty‐three PD patients with FOG were examined during their “off” medication state. The efficacy of the vibrotactile foot device was evaluated using a gait protocol comprising walking trials with vibrotactile stimulation “off” and “on.” Walking trials were videotaped for the offline rating by two movement disorder specialists. The Opal inertial sensor unit (128 Hz; Mobility Lab; APDM Inc., Portland, OR, USA) was used for quantitative gait analysis.ResultsThe results demonstrated 33.1% reduction in number of FOG episodes (P < 0.001) and 32.6% reduction of freezing episodes (P < 0.001). Quantitative gait analysis showed a significant increase in step length (P = 0.033). A moderate negative correlation was observed between the change of percent time frozen and age (r = −0.415, P = 0.016). 73% of participants reported minimal to substantial improvement in walking with this vibrating stimulation delivered by the vibrotactile foot device.ConclusionsThe vibrotactile foot device is an efficient device that could significantly reduce freezing severity and provide gait regulation to patients with PD experiencing frequent freezing. It could potentially be used in the home environment for improving the quality of life.

Authors: Altamirano Juan Manuel , Salinas‐Barboza Karla 
Published: August 2024

ABSTRACTBackgroundThe complexities of unilateral dystonia have led to exploring simultaneous (dual) globus pallidus internus (GPi) and motor ventral thalamus (Vim/Vop) deep brain stimulation (DBS), yet detailed assessments are lacking.ObjectivesTo assess the efficacy of GPi, Vim/Vop, and dual DBS in unilateral dystonia.MethodsThree patients with unilateral dystonia (two idiopathic, one acquired), implanted with two DBS electrodes targeting ipsilateral Vim/Vop and GPi, were included. Three stimulation modalities were assessed. First, one electrode was activated, then the other, and finally, both electrodes were activated simultaneously.ResultsDBS yielded substantial symptomatic reductions in all three evaluated stimulation modalities. Patients exhibited varying responses regarding quality‐of‐life and depressive symptoms. Treatment satisfaction didn't align with clinical improvements, potentially affected by unrealistic expectations.ConclusionsThis study contributes critical insights into GPi, Vim/Vop and simultaneous stimulation for unilateral dystonia. The safety of the procedure underscores the promise of this approach.

ScopeThis study aims to identify the gut enterotypes that explain differential responses to intervention with whole grain rye by proposing an “enterotype ‐ metabolic” model.Methods and resultsA 12‐week randomized controlled trial is conducted in Chinese adults, with 79 subjects consuming whole grain products with fermented rye bran (FRB) and 77 consuming refined wheat products in this exploratory post‐hoc analysis. Responders or non‐responders are identified according to whether blood glucose decreased by more than 10% after rye intervention. Compared to non‐responders, responders in FRB have higher baseline Bacteroides (p < 0.001), associated with reduced blood glucose (p < 0.001), increased Faecalibacterium (p = 0.020) and Erysipelotrichaceae_UCG.003 (p = 0.022), as well as deceased 7β‐hydroxysteroid dehydrogenase (p = 0.033) after intervention. The differentiated gut microbiota and metabolites between responders and non‐responders after intervention are enriched in aminoacyl‐tRNA biosynthesis.ConclusionThe work confirms the previously suggested importance of microbial enterotypes in differential responses to whole grain interventions and supports taking enterotypes into consideration for improved efficacy of whole grain intervention for preventing type 2 diabetes. Altered short‐chain fatty acids and bile acid metabolism might be a potential mediator for the beneficial effects of whole grain rye on glucose metabolism.

AbstractPurposeCompared with lower field strengths, DWI at 7 T faces the combined challenges of increased distortion and blurring due to B0 inhomogeneity, and increased signal dropouts due to B1+ inhomogeneity. This study addresses the B1+ limitations using slice‐specific static parallel transmission (pTx) in a multi‐shot, readout‐segmented EPI diffusion imaging sequence.MethodsDWI was performed in 7 healthy subjects using MRI at 7 T and readout‐segmented EPI. Data were acquired with non‐pTx circular‐polarized (CP) pulses (CP‐DWI) and static pTx pulses (pTx‐DWI) using slice‐specific B1+ shim coefficients. Each volunteer underwent two scan sessions on the same day, with two runs of each sequence in the first session and one run in the second. The sequences were evaluated by assessing image quality, flip‐angle homogeneity, and intrasession and intersession repeatability in ADC estimates.ResultspTx‐DWI significantly reduced signal voids compared with CP‐DWI, particularly in inferior brain regions. The use of pTx also improved RF uniformity and symmetry across the brain. These effects translated into improved intrasession and intersession repeatability for pTx‐DWI. Additionally, re‐optimizing the pTx pulse between repeat scans did not have a negative effect on ADC repeatability.ConclusionThe study demonstrates that pTx provides a reproducible image‐quality increase in multishot DWI at 7 T. The benefits of pTx also extend to quantitative ADC estimation with regard to the improvement in intrasession and intersession repeatability. Overall, the combination of multishot imaging and pTx can support the development of reliable, high‐resolution DWI for clinical studies at 7 T.

Authors: Sabermahani S. , Ordokhani Y. , Razzaghi M. 
Published: August 2024

AbstractGeneralized Lucas wavelets (GLWs) have two more parameters ( and ), comparing with some existing classical wavelet functions. In this manner, we have different types of wavelet functions (orthogonal and non‐orthogonal) by choosing various values of parameters and . Due to the impressive feature of the GLWs, we design a new computational method for the solution of fractional optimal control problems and fractional pantograph optimal control problems. This technique uses the GLWs and least squares method. The scheme includes expanding the required functions using GLW elements. We present new Riemann–Liouville and pantograph operational matrices for GLWs. Applying the operational matrices and least squares method, the considered problems lead to systems of algebraic equations, which can be solved numerically. A brief discussion of the error of the estimate used is investigated. Finally, some numerical experiments are exhibited to demonstrate the validity and applicability of the suggested scheme. The proposed algorithm is easy to implement and presents very accurate results.

AbstractAn environmentally sustainable method was used to synthesize a novel class of biopolymer‐based PVP/ZnO nanocomposites (NCs) with pomegranate peel residue extract as a biosurfactant, zinc acetate as the primary material, PVP as the stabilizing substance and sodium hydroxide as the resolving product. Significant global concerns for human health and the environment are caused by the presence of disease‐causing microbes and toxic dyes in water supplies. Zinc oxide nanoparticles (ZnO NPs) exhibit exceptional photocatalytic and antibacterial efficacy toward reactive dye and bacterial strains. The microstructure of the NPs was analyzed by employing X‐ray diffraction (XRD), with a size of 20.24 nm. Investigation using field emission scanning electron microscopy (FE‐SEM) revealed the appearance of nanoflakes‐shaped PVP‐ZnO nanoparticles with a size ranging from 20 to 30 nm. The mixed composition of the nanoparticles was demonstrated using Fourier Transform Infrared Spectroscopy (FT‐IR), and an intensity of absorption at 346 nm was seen using UV–Vis spectroscopy. The PVP‐ZnO nanoparticles demonstrated exceptional photocatalytic efficacy, destroying about 90% of the reactive MB dye. The NPs exhibited antibacterial activity against E. aerogenes, S. aureus, P. aeruginosa, and K. pneumonia, with boundaries of inhibition of 21, 19, 18, and 16 mm, correspondingly. The results indicate that PVP‐ZnO nanoparticles may be efficiently employed for water purification, successfully removing both dye and pathogenic pollutants.

AbstractStarch‐based biocomposites exhibit great potential as an alternative to fossil‐based materials. This work focused on investigating the properties of the starch‐based biocomposite reinforced by cellulose nanofibers derived from sugarcane bagasse (SCB). The sodium hydroxide (NaOH) concentration was varied from 4%, 8%, and 12% wt/vol for the SCB extraction process. The obtained nanofibers, respectively called SCBNF4, SCBNF8, and SCBNF12, were characterized by various techniques prior to being incorporated into modified starch (MS). The effects of the type and amount of SCBNF on the mechanical properties, thermal behavior, optical transparency, and moisture absorption of the biocomposite films were examined. All SCBNF samples had a cellulose type I structure with a diameter on the nanometer scale, regardless of the NaOH concentration. The SCBNF's diameter decreased, whereas the crystallinity index increased with increasing NaOH concentration. When incorporated into MS, the higher SCBNF loading resulted in enhancements of mechanical properties and resistance to moisture absorption with the sacrifice of optical transparency. The biocomposite filled with SCBNF12 exhibited better overall performance at a certain filler loading due to the greater filler‐polymer interaction. The benefits of greater strength, light weight, and eco‐friendliness of the developed biocomposites make them suitable for many applications, including packaging.Highlights
Diameter and crystallinity index of SCBNF were governed by NaOH concentration.
Adding SCBNF to MS greatly improved the biocomposite's mechanical properties.
SCBNF12 showed the highest biocomposite's overall performance.
The maximum strength was achieved at 1 phr of SCBNFs.
The addition of SCBNFs reduced water and moisture absorption.
Real world prescription of beta‐blockers in patients with asthma
Authors: Lee Jihyun , Chun Pusoon 
Published: August 2024

AbstractPurposeThis study aimed to investigate the prescription of beta‐blockers (β‐blockers) for patients with asthma.MethodsIn this retrospective cross‐sectional study using the National Patient Sample (NPS) of the Health Insurance Review and Assessment Service (HIRA) of South Korea, β‐blockers and asthma medications were investigated using generic name codes provided by HIRA. Concomitant administration was identified when a β‐blocker and an asthma medication were co‐prescribed in one billing statement or when separate β‐blocker and asthma prescriptions had overlapping dates of use.ResultsIn the 1027 patients with asthma who were prescribed non‐selective β‐blockers (non‐SBs), 3087 non‐SB prescriptions were identified, of which 62.3% and 37.3% were for carvedilol and propranolol, respectively. Of the 906 patients with asthma prescribed selective β‐blockers (SBs), 2942 SB prescriptions were identified, of which 48.5%, 28.3%, and 20.3% were for bisoprolol, atenolol, and nebivolol, respectively. Overall, 2149 non‐SB and 2124 SB prescriptions with overlapping use dates with asthma medications were identified, which were prescribed to 726 and 657 patients, accounting for 70.7% and 72.5% of the patients receiving non‐SBs and SBs, respectively. β2‐agonists accounted for 39.9% of the concomitant asthma medications with overlapping dates of use with non‐SBs. Co‐prescribing of bronchodilators occurred at a rate of 38.7% and 45.1% for the 3087 non‐SB prescriptions and 2942 SB prescriptions, respectively.ConclusionsCarvedilol and propranolol accounted for half of all β‐blockers prescribed to asthma patients. Prescribing β‐blockers to patients with asthma requires caution to prevent exacerbation of asthma and drug interactions between β‐blockers and co‐prescribed asthma medications.
