Abstract

BACKGROUND:

Soft tissue integration (STI) around dental implant abutments is a prerequisite to prevent bacterial invasion and achieve successful dental implant rehabilitation. However, peri-implant STI is a major challenge after dental abutment placement due to alterations in the immune microenvironment upon surgical dental implant installation.

METHODS:

Based on known immunomodulatory effects of zinc, we herein deposited zinc/chitosan/gelatin (Zn/CS/Gel) coatings onto titanium substrates to study their effect on macrophages. First, we exposed macrophages to cell culture media containing different zinc ion (Zn2+) concentrations. Next, we explored the immunomodulatory effect of Zn/CS/Gel coatings prepared via facile electrophoretic deposition (EPD).

RESULTS:

We found that Zn2+ effectively altered the secretome by reducing the secretion of pro-inflammatory and enhancing pro-regenerative cytokine secretion, particularly at a Zn2+ supplementation of approximately 37.5 μM. Zn/CS/Gel coatings released Zn2+ in a concentration range which effectively stimulated pro-regenerative macrophage polarization as demonstrated by M2 macrophage polarization. Additionally, the impact of these Zn2+-exposed macrophages on gingival fibroblasts incubated in conditioned medium showed stimulated adhesion, proliferation, and collagen secretion.

CONCLUSION:

Our promising results suggest that controlled release of Zn2+ from Zn/CS/Gel coatings could be applied to immunomodulate peri-implant STI, and to enhance dental implant survival.

Published: November 2024

AbstractIn the current work, the effect of the surface phase structure of silicon wafer on the copper assisted chemical etching (Cu-ACE) behavior was investigated by adopting N-type monocrystal silicon with different thickness as raw material. An inverted pyramid structure was prepared with the method of Cu-ACE, which exhibited a mild reaction temperature with the reflectance reaching as low as 6.34%. Furthermore, cetyltrimethylammonium bromide (CTAB) was employed as an additive to optimize the Cu-ACE process. The study revealed that CTAB molecules could adsorb Cu2+ near the silicon wafer surface in the HF/Cu(NO3)2/H2O2 solution, thereby promoting the deposition of copper particles and ensuring a uniform etching reaction. When 3 mg of CTAB was added to 100 mL of etching solution, the inverted pyramid structure showed larger dimensions and was more uniformly distributed, an excellent antireflection effect was achieved with the reflectance significantly reduced from 10.8% to 4.6%. This process could stably fabricate inverted pyramid structures, and is expected to advance the development of high-efficiency single-crystal solar cells in the future.

Abstract
Purpose
This narrative review aims to conduct a comparative analysis of dietary and non-dietary approaches in the management of weight and disordered eating behaviors (DEBs) in adults with obesity.

Methods
Studies were identified from Medline (PubMed), including only English-language manuscripts published from 1998 to 2024. To be included in the review the studies had to be RCTs that compared the effect of dietary and non-dietary approaches on weight loss and DEBs in adults with obesity not being treated with pharmacological treatments.

Results
Seven randomized controlled trials (RCTs) reported in 8 manuscripts published between 1998 and 2024 met the inclusion criteria. The sample size ranged from a minimum of 16 subjects to a maximum of 219. All studies involved adult subjects, mainly women, with first-, second-, or third-degree obesity and most subjects had cognitive restriction and/or uncontrolled eating. Dietary approaches were characterized by moderate caloric restriction (CR) and restriction of fat intake. In contrast, non-dietary approaches focused on mindful eating (ME), intuitive eating (IE) and weight neutral (WN) approaches. Of the 7 RCTs included, 5 reported greater weight loss in the diet group compared to the non-diet group; however, only one of these sustained the result at follow-up. In contrast, 4 studies demonstrated greater improvements in DEBs in the non-diet group.

Conclusion
CR is essential for weight loss in individuals with obesity, but long-term weight management also hinges on their relationship with food. The psychological improvements reported in non-dietary versus dietary approaches should not be overlooked and can be a starting point for the development of multidisciplinary interventions involving synergistic actions between diet, exercise, and practices to improve DEBs with the goal of reducing the obesity epidemic.

Published: November 2024

AbstractWearable sensing systems have been designed to monitor health conditions in real-time by detecting analytes in human biofluids. Wound diagnosis remains challenging, necessitating suitable materials for high-performance wearable sensors to offer prompt feedback. Existing devices have limitations in measuring pH and the concentration of pH-dependent electroactive species simultaneously, which is crucial for obtaining a comprehensive understanding of wound status and optimizing biosensors. Therefore, improving materials and analysis system accuracy is essential. This article introduces the first example of a flexible array capable of detecting pyocyanin, a bacterial virulence factor, while correcting dynamic pH fluctuations. We demonstrate that this combined sensor enhances accuracy by mitigating the impact of pH variability on pyocyanin sensor response. Customized screen-printable inks were developed to enhance analytical performance. The analytical performances of two sensitive sensor systems (i.e., fully-printed porous graphene/multiwalled carbon nanotube (CNT) and polyaniline/CNT composites for pyocyanin and pH sensors) are evaluated. Partial least square regression is employed to analyze nonzero-order data arrays from square wave voltammetric and potentiometric measurements of pyocyanin and pH sensors to establish a predictive model for pyocyanin concentration in complex fluids. This sensitive and effective strategy shows potential for personalized applications due to its affordability, ease of use, and ability to adjust for dynamic pH changes.

Published: November 2024

AbstractThe increasing centralization of the Web raises serious concerns regarding privacy, security, and user autonomy. In response, there has been a renewed interest in the development of secure personal information management systems and a movement towards decentralization. Decentralized personal online data stores (pods) represent a revolutionary example within this movement, built on the W3C’s existing guidelines – an approach exemplified by initiatives such as (https://solidproject.org). In the Solid paradigm, individuals store their personal data in pods and have absolute discretion when choosing to grant access to different users and applications. A barrier to the adoption of the pod approach is the predominant reliance on centralized indexes for search functionality in current Web and Web-based systems. This paper introduces the framework, which is designed to facilitate this new paradigm of large-scale searches within personal data stores while respecting the individual pod owners’ data access governance. The current ESPRESSO prototype integrates access control within pod indexes to enhance distributed keyword-based search. ESPRESSO’s unique contribution not only enhances search capabilities on the decentralized Web but also paves the way for future explorations in decentralized search technologies.

Abstract
E-waste management is a major environmental concern that also poses serious risks to occupational health. While e-waste workers are exposed to a variety of chemicals, little is known about occupational exposure to microbiological agents. This study aims to fill that gap. For that purpose, two e-waste facilities were assessed: one battery-recycling facility (BRF), and another facility (SRE) dedicated to e-waste sorting and storage before sending it for different processing. Filtering respiratory protection devices (FRPD, 24 samples) and settled dust (13 samples) were collected using standardized sampling approaches, and analyzed by culture-based, chemical and molecular methods. Workers also filled in a questionnaire regarding work activities and the use of FRPD. Microbial contamination, fungal diversity, azole resistance, and prevalence of Aspergillus sections Fumigati and Flavi (as surrogates of harmful fungal contamination) and mycotoxins were determined. To estimate potential health effects related to exposure, the FRPD cytotoxicity was determined in human A549 lung and HepG2 hepatic cells. Microbial contaminants with pathogenicity and toxigenic potential were observed in FRPD and settled dust. Aspergillus section Fumigati was widespread. The observed presence of Aspergillus section Flavi relates to the risk of exposure to aflatoxin B1 (a potent hepatocarcinogen). Four different mycotoxins were detected in 8% FRPD and 15% dust samples, including fumonisin B1 and sterigmatocystin (below the limit of quantification). A low to moderate cytotoxic effect of sampled FRPD was observed, with human lung alveolar cells more sensitive than hepatic cells. No relevant azole resistance was observed, nor correlations between fungal reduced azole-susceptibility and fungal growth at 37 °C or cytotoxicity. In summary, it can be concluded that this approach using FRPD and settled dust presents a promising potential for screening occupational exposure to microbiological contaminants in e-waste management. More studies in this occupational context should be prioritized to identify critical biological hazards and to support the implementation of appropriate health risk mitigation strategies.

AbstractIn this study, silicene nanosheets (SNs) were synthesized using molten salt chemical exfoliation. Polythiophene (PTh) and SNs/PTh nanocomposites were prepared through an in-situ chemical oxidative polymerization method. Raman spectroscopy confirmed the formation of SNs, PTh, and various SNs/PTh nanocomposites at different ratios. X-ray diffraction (XRD) analysis verified the presence of crystalline SNs, the amorphous nature of PTh, and the combination of crystalline SNs with amorphous PTh in the nanocomposites. Field-emission scanning electron microscopy (FESEM) revealed the morphology of silicene sheets and the distribution of PTh granular globes and flakes in the SNs/PTh nanocomposites. Transmission electron microscopy (TEM) showed transparent and reduced-stacking SNs, as well as aggregated PTh flakes and evenly distributed PTh flakes over the SNs surface in the nanocomposites. Electrochemical tests indicated that SNs/PTh nanocomposites exhibited higher specific capacitance, energy density, and stable cycling performance compared to individual SNs and PTh. Cyclic voltammetry (CV) measurements showed that the best performing supercapacitor electrode, SNs/PTh-67 nanocomposite displayed a specific capacitance of 276.25 F/g at a scan rate of 5 mV/s and delivered an energy density of 13.8 Wh/kg. The SNs/PTh-67 nanocomposite also exhibited excellent cycling stability with a capacitance retention of 85.9% after 2000 consecutive charge–discharge cycles at a current density of 4 A/g. This study demonstrates the potential of SNs/PTh-67 nanocomposite as a stable and high-performance electrode material for supercapacitors.

Published: November 2024

AbstractThe twenty-first century has become synonymous with two primary architectural concepts: sustainability and digital technologies. While the former seeks less carbon footprint within the built environment, the latter drives a novel approach towards efficient and effective productivity. However, previous findings show inadequate study on Emerging Digital Technologies (EDTs) and their Awareness in Higher Educational Institutions (HEIs), especially in the Global South. In light of this, the study primarily aims to evaluate the perceived Awareness of students of EDTs within architectural educational institutions in Ghana. The study used a quantitative approach, obtaining data from 243 respondents using a questionnaire. Findings revealed students were aware of most EDTs, indicating an interest specifically in Computer-Aided Design and Building Information Modelling software. However, the students perceived little Awareness and interest in robotics and nanotechnology. Furthermore, the students perceived that inadequate tools and equipment are vital influences that limit their Awareness of EDTs. The authors recommend that HEIs review curricula to incorporate EDTs and collaborate with digital agencies to create an effective environment for students to increase their interest and proficiency in EDTs in architecture. There should also be continuous capacity building for the architectural HEI staff to ensure the transfer of relevant skills in contemporary EDTs in the industry. Moreover, further studies must be conducted into a standardized framework for introducing EDTs in architectural education.
Advancing insights into virus-induced neurodevelopmental disorders through human brain organoid modelling

Published: November 2024

Abstract
Human neurodevelopment is a complex process vulnerable to disruptions, particularly during the prenatal period. Maternal viral infections represent a significant environmental factor contributing to a spectrum of congenital defects with profound and enduring impacts on affected offspring. The advent of induced pluripotent stem cell (iPSC)-derived three-dimensional (3D) human brain organoids has revolutionised our ability to model prenatal viral infections and associated neurodevelopmental disorders. Notably, human brain organoids provide a distinct advantage over traditional animal models, whose brain structures and developmental processes differ markedly from those of humans. These organoids offer a sophisticated platform for investigating viral pathogenesis, infection mechanisms and potential therapeutic interventions, as demonstrated by their pivotal role during the 2016 Zika virus outbreak. This review critically examines the utilisation of brain organoids in elucidating the mechanisms of TORCH viral infections, their impact on human brain development and contribution to associated neurodevelopmental disorders.

Abstract
This study aimed to assess nutritional status and associated factors among adult tuberculosis patients in public health centres in Horro Guduru Wollega Zone, Western Ethiopia, 2021. An institutional-based cross-sectional study was conducted among 334 randomly selected adult TB patients at public health centres from May 7, 2021, to June 21, 2021. Data were collected using structured questionnaires and anthropometric measurements. The nutritional status was measured by using body mass index (BMI). Data was entered into EpiData version 4.6 and exported to SPSS version 25 for analysis. A bivariate and multivariable multinomial logistic regression analysis was done to identify factors associated with nutritional status. The prevalence of under and overnutrition was found to be 48.2% and 8.7%, respectively. Female TB patients (AOR = 3.48, 95% CI: (1.918–6.314)), patients who didn’t receive dietary counselling (AOR = 2.51, 95% CI: (1.335–4.720)), TB patients on the initiation phase of treatment (AOR = 3.76, 95% CI: (2.072–6.852)), and meal frequency less than three times per day (AOR = 3.6, 95% CI: (1.942–6.676)) were significantly associated with under nutrition. The prevalence of undernutrition was high in the study area. Being a female, being in the initiation phase of treatment, lack of dietary counselling, and having meal less than three per day were independently associated with undernutrition. Hence, regular nutritional assessments, dietary counselling, and nutritional support should be encouraged at the facility and community level.
Influence of Horizontal Model Resolution on the Horizontal Scale of Extreme Precipitation Events
Authors: Ali S. M. Anas , Tandon Neil F. 
Published: November 2024

AbstractA fundamental characteristic of extreme precipitation events (EPEs) is their horizontal scale. This horizontal scale can influence the intensity of an EPE through its effect on the timescale of an EPE as well as its effect on the strength of convective feedbacks. Thus, to have confidence in future projections of extreme precipitation, the horizontal scales of EPEs in global climate models (GCMs) should be evaluated. Analyzing daily output from 27 models participating in the Coupled Model Intercomparison Project phase 6 (CMIP6), including 13 models participating in the High Resolution Model Intercomparison Project (HighResMIP), we computed the horizontal scales of EPEs and extreme ascent for annual maximum EPEs during 1981–2000. We found that the horizontal scales of both EPEs and the associated ascending motion are resolution‐dependent: for a factor of seven increase in horizontal resolution, the horizontal scale decreases by a factor of approximately two to five, with higher sensitivity in the tropics than in the midlatitudes. Further analysis in the southern hemisphere midlatitudes reveals that this resolution dependence results from precipitation during the simulated EPEs that is almost entirely resolved rather than parameterized. However, the EPEs are not simply grid box storms, and analysis of the horizontal scales of geopotential anomalies suggests that the planetary‐scale dynamics in GCMs is not resolution‐dependent. Thus, the dominance of resolved precipitation during EPEs is more likely due to convection on the model grid or formation of strong, poorly resolved fronts, and additional work is needed to explore these possibilities and find a remedy for this resolution dependence.
Imaging Magma Reservoirs From Space With Altimetry‐Derived Gravity Data
Authors: Le Mével Hélène 
Published: November 2024

AbstractI investigate the detectability of magma reservoirs in the vertical gravity gradient (VGG) anomalies calculated from satellite altimetry data. First, I calculate a suite of synthetic seamount models to show the expected VGG anomaly characteristic wavelength and amplitude for a simplified magmatic system, hydrothermal system, and a caldera infill, varying their dimensions for a given depth and density contrast. I find that most magmatic and hydrothermal systems create VGG anomalies with a characteristic wavelength and amplitude greater than the data uncertainty and are therefore detectable. The proposed approach consists in three main steps: (a) calculate the VGG from the two components of the deflection of the vertical, (b) calculate and remove the gravity contribution of the bathymetry interface using an independent bathymetry data set (e.g., acquired by multibeam echosounders) to obtain a VGG Bouguer gravity anomaly, (c) invert the Bouguer VGG anomaly to obtain a 3D density model. I image a 6‐by‐8‐km low density body between 3 and 9 km depth under Brothers volcano in the Kermadec arc. I hypothesize that it represents the main magmatic system, possibly with a minor fraction of hydrothermal fluids at the shallower depths. There are about 225 submarine volcanoes globally that could be studied with satellite altimetry‐derived gravity data to potentially image their magmatic system. Future altimetry data will increase the gravity data resolution and allow us to image smaller features. This is thus an invaluable data set for the study of underexplored submarine volcanoes and can help improve our volcano hazards assessment.
