Authors:   The Table and Food Coordinate Society of Korea, Kim Yang Suk , Cheon Hee Soon , Kim Bumsik
Published: April 2023

Soy pulp, a food by-product derived from tofu and soy milk production, is rich in insoluble dietary fiber, β-conglycinin, and isoflavones. The researchers developed hangover pills incorporating soy pulp. This study aims to investigate the effects of soy pulp extract-based hangover pills on antioxidant and alcohol-degrading activity through in vitro and human tests, including DPPH and ABTS radical scavenging activity, as well as breath alcohol concentration. Eighteen healthy volunteers participated in this randomized crossover study. The participants were randomly assigned to either the soy pulp mixture (SPM) intake group or the non-intake (PLA) group. The difference in blood alcohol concentration between the test and control groups was measured as the primary outcome. The breath alcohol concentration in the SPM group was significantly reduced by 35% after 15 minutes and 36% after 30 minutes compared to the PLA group post-alcohol consumption. DPPH and ABTS radical scavenging activity of SPM increased in a dose-dependent manner. SPM demonstrated higher antioxidant activity than both PLA and hangover pills from Company A. Therefore, hangover pills containing soy pulp, which exhibit antioxidant and anti-hangover effects, are anticipated to play a role in alleviating hangovers, aligning with the health and convenience needs of modern individuals.

Theoretical treatments of polymer dynamics in liquid generally start with the basic assumption that motion at the smallest scale is heavily overdamped; therefore, inertia can be neglected. We report on the Brownian motion of tethered DNA under nanoconfinement, which was analyzed by molecular dynamics simulation and nanoelectrochemistry-based single-electron shuttle experiments. Our results show a transition into the ballistic Brownian motion regime for short DNA in sub-5-nm gaps, with quality coefficients as high as 2 for dsDNA, an effect mainly attributed to a drastic increase in stiffness. The possibility for DNA to enter the underdamped regime could have profound implications on our understanding of the energetics of biomolecular engines such as the replication machinery, which operates in nanocavities of a few nanometers wide.

Published: April 2023

The biosynthesis of glycopeptide antibiotics such as vancomycin and other biologically active biaryl-bridged and diaryl ether-linked macrocyclic peptides includes key enzymatic oxidative phenol macrocyclization(s) of linear precursors. However, a simple and step-economical biomimetic version of this transformation remains underdeveloped. Here, we report highly efficient conditions for preparing biaryl-bridged and diaryl ether-linked macrocyclic peptides based on multicopper(II) catalysts. The selective syntheses of ring models of vancomycin and the arylomycin cyclic core illustrate the potential of this technology to facilitate the assembly of complex antibiotic macrocyclic peptides whose syntheses are considered highly challenging. The unprecedented ability of multicopper clusters to chelate tethered diphenols and promote intramolecular over intermolecular coupling reactions demonstrates that copper clusters can catalyze redox transformations that are not accessible by smaller metal catalysts.
From Single-Particle to Collective Dynamics in Supercooled Liquids
Authors: Matyushov Dmitry , Richert Ranko
Published: April 2023

It has been recognized recently that the considerable difference between photon-correlation (PCS) and dielectric (BDS) susceptibility spectra arises from their respective association with single-particle and collective dynamics. This work presents a model that captures the narrower width and shifted peak position of collective dynamics (BDS), given the single-particle susceptibility derived from PCS studies. Only one adjustable parameter is required to connect the spectra of collective and single-particle dynamics. This constant accounts for cross-correlations between molecular angular velocities and the ratio of the first-rank and second-rank single-particle relaxation times. The model is tested for three supercooled liquids, glycerol, propylene glycol, and tributyl phosphate, and is shown to provide a good account of the difference between BDS and PCS spectra. Since PCS spectra appear to be rather universal across a range of supercooled liquids, this model provides a first step toward rationalizing the more material specific dielectric loss profiles.
Determination of Ideal Conditions for the Production of Hydroxyl Radicals through Spectroscopy of Ferric Thiocyanate and Methyl Orange
Authors: Maken Nirbaan
Published: April 2023

When the human body comes in contact with radiation, water breaks down into ROS, Reactive Oxidative Species such as hydroxyl radicals, in a process called radiolysis. With the presence of hydroxyl radicals (HOᐧ) and other ROS, DNA in the human body is susceptible to mutations. While hydrogen peroxide (H₂O₂), a product of radiolysis, may not be a strong ROS on its own, it can react with certain metals such as Iron(II) to produce hydroxyl radicals in a process called the Fenton Reaction. This study aimed to use the cost-effective spectroscopic study of Ferric Thiocyanate and Methyl Orange to determine optimum conditions for the Fenton Reaction. Understanding conditions and methods of detecting products of the Fenton Reaction is key to determine how and under what circumstances hydroxyl radicals are readily produced in the human body, putting humans at risk of cancer. Through the spectroscopic analysis of FeSCN2+ and degradation of Methyl Orange, it was determined that the Fenton Reaction occurred ideally at a pH between 2.0-4.0 with low temperature dependence. Furthermore, both spectroscopic methods were viable options for detecting the efficiency of Fenton Processes.
Complex formation of Cucurbit[6]uril with DABCO and DABCO derivatives: An experimental and DFT study
Authors: Wego Andreas , Zielesny Achim
Published: April 2023

The complex formation of Cucurbit[6]uril with DABCO and DABCO derivatives in solution has been studied using calorimetric titrations. For a better understanding of factors influencing the complex formation, several DABCO derivatives have been synthesized. All compounds have been characterized. Inclusion complex formation could not be observed. Even with dumbbell derivatives of DABCO threading through the Cucurbit[6]uril cavity does not occur. As a result, no rotaxanes have been formed in solution. These results are in accordance with DFT calculations.
Coupled cluster finite temperature simulations of periodic materials via machine learning
Authors: Herzog Basile , Gallo Alejandro , Hummel Felix , Badawi Michael , Bučko Tomáš , Lebègue Sébastien , Grüneis Andreas , Rocca Dario
Published: April 2023

Density functional theory is the workhorse of materials simulations. Unfortunately, the quality of results often varies depending on the specific choice of the exchange-correlation functional, and this significantly limits the predictive power of this approach. Coupled cluster theory, including single, double and perturbative triple particle-hole excitation operators, is widely considered as the `gold standard` of quantum chemistry as it can achieve chemical accuracy for non-strongly correlated applications. Because of the high computational cost, the application of coupled cluster theory in materials simulations is rare, and this is particularly true if finite-temperature properties are of interest for which molecular dynamics simulations have to be performed. By combining recent progress in machine learning models with low data requirements for energy surfaces and in the implementation of coupled cluster theory for periodic materials, we show that chemically accurate simulations of materials are practical and could soon become significantly widespread. As an example of this numerical approach, we consider the calculation of the enthalpy of adsorption of CO2 in a porous material.

Authors: Gerken James , Stamoulis Alexios , Stahl Shannon
Published: April 2023

Integrated rate equations are straightforward to fit to experimental data to verify a proposed mechanism and extract kinetic parameters. Such equations are derived for reversible disproportionation/comproportionation reactions with any set of initial concentrations. Extraction of forward and reverse rate constants from experimental data by fitting the rate law to the data are demonstrated for the disproportionation of TEMPO (2,2,6,6-tetramethyl-1-piperidinyl-N-oxyl) under acidic conditions where the approach to equilibrium is observed.

Evaluation of Post-Cementation Sensitivity After Cementation with Bio-Active Luting Cement - A Randomized Clinical Control Trial
Authors: Vasudevan Sneha , N Shamnur Sunitha , DB Nandeeshwar , Kumar KR Pavan
Published: April 2023

Background The most common complaint following cementation is the occurrence of post cementation sensitivity. The sensitivity to cold stimulus after cementation can be indicative of a gap present below the crown or a marginal gap connecting to opened tubules which emerge into the pulp. A pulp fluid outflow occurs as a result of the contraction of dentinal fluid in this gap which causes postoperative sensitivity. Thus luting agents should form complete seal between fabricated restoration and prepared tooth.Objectives The current study was conducted to clinically evaluate post-cementation hypersensitivity of bioactive luting cement in a randomized clinical control trial using resin modified glass ionomer cement RMGIC as the control.Methods According to standard tooth preparation protocol the teeth were prepared to receive Porcelain fused to metal PFM bridges on both sides of the mouth. PFM final restorations were cemented using Bioactive and RMGIC luting cement. Sensitivity was tested by using compressed airbiting pressure tests and cold water and was evaluated by using Schiff scale with 0-3 scores before cementation soon after cementation one week and three months post cementation.Results Almost all the patients responded to hypersensitivity at pre-cementation and baseline with compressed airbiting pressure tests and cold water. The sensitivity scores reduced over time one week and three months for both the luting agents.Conclusion Based on the results it can be concluded that the bioactive luting cement exhibited lesser sensitivity scores when compared to resin modified GIC luting cement.

Authors: Kumar N Kiran , Merwade Seema , Shylaja V Dr. , H S Preetham , Swathisha P Annie
Published: April 2023

Background Dental caries is a multifactorial disease that results from an imbalance between pathological and protective factors. The imbalance produced favors demineralization of enamel. If detected early non-cavitated lesions can be reverted with the help of remineralizing agents. The role of calcium-phosphate remineralization systems and the ErYAG and diode lasers in the treatment of these lesions has recently been taken into account.Aim The aim of the study was to evaluate the remineralization potential of Erbium-doped yttrium aluminium garnet laser ErYAG laser diode laser combined with MI varnish on the depth of remineralization of incipient carious lesions.Methods Forty eight human premolars were collected conditioned with demineralizing agents to create artificial carious lesions. Then the samples were coated with nail paint leaving a uncoated window of 4 mmtimes 4 mm facially. The samples were then randomly divided into four groups n12 Group I ndashControl Group II ndashMI Varnish Group III ndash MI Varnish ErYAG laser and Group IV ndashMI Varnish Diode laser. For a period of seven days specimens were conditioned with remineralizing agents followed by laser irradiation. Confocal laser scanning microscopy CLSM was used to assess the depth of demineralization and remineralization. Statistical Package SPSS 22.0 SPSS Inc. Chicago IL was used to analyze the data. KruskalndashWallis test was used to analyze the difference between the groups and post hoc MannndashWhitney test was used to compare the differences between the groups. The level of significance was set at p lt0.05.Results Samples in Group III showed greater remineralization depth 1488.235 compared to other groups with statistically significant p lt0.001.Conclusion Within the limitations of this in vitro study MI varnish alone is less effective compared to laser groups MI varnish ErYAG and MI varnish Diode laser which showed increased remineralization depths.

Authors: Afreen Noor Rana , Reddy C Divya , T Paul Santhosh
Published: April 2023

Background Tooth brushing behaviours in children have been significantly associated with their oral health status and susceptibility to dental caries. Adoption of proper and consistent tooth brushing habits early in life will help in establishing the same in their adulthood. Therefore this study aimed to understand and assess the tooth brushing habits of preschool children in Bengaluru city Karnataka.Methodology Primary caregivers of 102 preschool children from selected preschools in Bengaluru were included in the study. A self-administered questionnaire was distributed and the responses were collected. The questionnaire consisted of questions pertaining to demographic information of both the child and the parents and questions regarding the tooth brushing habits of children. All the responses were tabulated and subjected to statistical analysis.Results It was noted that 60 of the primary caregivers introduced tooth brushing to their children from 6 months to 1 year of age which coincided with the time of eruption of the first tooth in the oral cavity. The majority of the children 61 did not brush their teeth twice daily and this showed a significant association with the frequency of brushing of mothers with 59 of mothers reporting to brushing their teeth once a day. It was reported that 58 of the pre-schoolers brushed their teeth on their own without any adult supervision. It was alarming to see that 70 of the caregivers did not receive any information or education pertaining to the maintenance of oral hygiene in their children.Conclusion The results of this study highlight the urgent need for the establishment of proper oral hygiene habits in young children as this behaviour is amenable to change leading to a positive impact on oral health.

Authors: Prasada L Krishna , . Suhas , Kumar Pai Akshay
Published: April 2023

Background A splint is recommended after toothteeth repositioning to stabilize the toothteeth and optimize healing outcomes of the pulp andor periodontal tissues. A splint is defined as an appliance used to support protect or fixate a tooth that has been loosened reimplanted fractured or undergone certain endodontic surgical procedure.Aim To analyze and determine the effect of certain factors like duration of splinting materials used for splinting and the splinting technique on long term prognosis of traumatized teeth.Methodology This review was conducted as per the PRISMA and JBI guidelines. A total of five randomized clinical trials published over the past 30 years were included in the qualitative synthesis.Results A total of 874 replanted repositioned permanent teeth from five publications reporting short-term up to 14 days and long-term ge14 days splinting according to current clinical guidelines were pooled. Evidence for the association between short-term splinting and increased odds of functioning reduced periodontal healing acceptable healing or replacement resorption seems decisive. This study found no evidence of contraindications. Splinting duration was found to have no effect on the success of reimplantation. With future research to the contrary pending dentists are advised to continue using the current recommended splinting duration when reimplanting avulsed permanent teeth.Conclusion This study found no evidence of contraindications to current guidelines suggesting that the success of periodontal healing after reimplantation is not affected by the duration of splinting. It is recommended that the dentists continue to use the current recommended splinting duration for reimplanting avulsed teeth
An Antique Approach to Frenectomy: Replenishing Functional Esthetics - A Case Report
Authors: Varshitha KV , S Pudakalkatti Pushpa , Satya Kurada , BR Sowmya
Published: April 2023

Frenectomy is total eradication of the anomalous frenum along with its attachment from the underlying bone. Pretreatment frenums are prone for relapse after orthodontic treatment. To attenuate the relapse phenomenon frenectomies are performed post orthodontically. A diastema closure patient was referred to our department by an orthodontist for frenectomy six weeks prior to removal of the orthodontic appliance. There have been several methods suggested for removing these incorrect frenal attachments. Considering the disadvantages of the Archerrsquos classical frenectomy procedure we contemplated the technique of laterally displaced flap to balance the functional esthetics of the aberrant frenulum attachment post completion of the orthodontic treatment. The current paper discusses the management of the above mentioned case using Millers technique which combines the frenectomy with a lateral pedicle flap yielding good aesthetic results with minimal scar tissue formation resulting in improved healing.

Restoring Dental Rubbles Using an Overlay Removable Partial Denture Fabricated with Digital Technology - A Case Report
Authors: Eshwar Adarsh , PS Manoharan , Abinayam V
Published: April 2023

Regressive changes of natural dentition may be a physiologic or pathologic process which proceeds to drastic occlusal wear. Loss of incisal or occlusal edge morphology due to functional or parafunctional activity of teeth can be regarded as physiologic whereas frictional action of a foreign body on the teeth or loss of tooth substance due to a chemical process involving bacteria may be termed as pathogenic. These result in loss of occlusal vertical dimension and may elicit occlusal instability compromised function and aesthetics.The treatment modalities for the same are confined to fixed prosthesis for restoration of the lost vertical dimension. But this technique in general is expensive technique sensitive and complex. An Overlay Removable Partial Denture ORPD though rarely reported in the literature can be considered as one of the alternative interim or even a permanent dental prosthesis. The proposed paper is a case report of worn dentition rehabilitated with ORPD. This approach was found to be non-invasive simple and cost effective. The patient on short term follow-up reported with optimal aesthetics and masticatory efficiency. Overall satisfaction and quality of life improved after the treatment.
Constructing density forecasts from quantile regressions: multimodality in macro-financial dynamics
Authors: Mitchell James , Poon Aubrey , Zhu Dan
Published: April 2023

Quantile regression methods are increasingly used to forecast tail risks and uncertainties in macroeconomic outcomes. This paper reconsiders how to construct predictive densities from quantile regressions. We compare a popular two-step approach that fits a specific parametric density to the quantile forecasts with a nonparametric alternative that lets the "data speak." Simulation evidence and an application revisiting GDP growth uncertainties in the US demonstrate the flexibility of the nonparametric approach when constructing density forecasts from both frequentist and Bayesian quantile regressions. They identify its ability to unmask deviations from symmetrical and unimodal densities. The dominant macroeconomic narrative becomes one of the evolution, over the business cycle, of multimodalities rather than asymmetries in the predictive distribution of GDP growth when conditioned on financial conditions.

Rent, borrow and...benefit? Exploring New Zealanders' intentions to rent and borrow consumer goods using an extension of the Theory of Planned Behaviour
Authors:   , Frude Elizabeth
Published: April 2023

Overconsumption of consumer goods has detrimental impacts on the environment. Shifting away from this harmful practice is imperative. Therefore, alternative ways to access goods, without having to own them, are necessary. Such opportunities already exist and are referred to as forms of collaborative consumption. While the idea of collaborative consumption is well-received, its uptake remains low. Therefore, research to understand what motivates people to engage in collaborative consumption is valuable.

Two examples of collaborative consumption are peer-to-peer (P2P) renting and borrowing from ‘non-traditional’ libraries. So far, few studies have investigated what encourages individuals to engage in, or conversely, discourages individuals from engaging in these behaviours. Additionally, there appears to be a lack of studies that have applied the Theory of Planned Behaviour (TPB) to explore the determinants of intention to rent and borrow consumer goods. This study aims to address these research gaps. Specifically, this study explores people’s motivations to engage in P2P renting and library borrowing using an extended version of the TPB that includes descriptive norm and personal norm. This study also identifies and explores the underlying beliefs that determine P2P renting and library borrowing.

Results indicate that attitude is the strongest predictor of intention to rent and borrow consumer goods. A favourable attitude toward P2P renting is determined by the beliefs that renting saves money, that items will be in a good condition and that it has social benefits. Although a favourable attitude toward library borrowing is also determined by those same beliefs conversely, a favourable attitude toward library borrowing is even more strongly determined by the beliefs that borrowing benefits the environment and reduces storage needs. The implications of these findings can be used to develop campaigns aimed at encouraging further uptake of P2P renting and library borrowing.
Millimeter-Wave Monopulse Filtenna Array with Directive Dielectric Resonators
Authors: Park Seung-Jun , Park Jeong-Hun , Lee Moon-Que
Published: April 2023

This paper presents a new millimeter-wave monopulse dielectric resonator (DR) filtering antenna (filtenna) array based on substrate-integrated waveguide (SIW) technology. The monopulse comparator realized by a square dual-mode (TE102 and TE201) SIW feed cavity uses diagonal irises, of which couplings between the feed and next-stage cavities lead to almost identical filter responses for the sum and difference channels with compact size and a planar single-substrate structure. Both dielectric resonator antennas (DRAs) adopting HEM133 mode for enhanced directivity are implemented with two filters based on SIW. The DR acts as the last resonator and the radiator in the filtenna. The prototype is designed at the Ka-band with a center frequency of 27.65 GHz and an operation bandwidth of 700 MHz. The measurement shows a 15-dB fractional bandwidth of 2.36%, a gain of 10.84 dBi for the sum channel, and a null depth of -15.6 dB for the difference channel.

This paper presents a high-gain wideband circularly polarized antenna composed of an end-fire dipole array antenna integrated with a metasurface. The antenna consists of a two-layer cascaded non-uniform metasurface made up of 4 × 4 circular patches with cross-slots of unequal lengths placed above an end-fire dipole array antenna with an air gap between the structures. The end-fire dipole array antenna comprises four equally spaced dipole elements, and each dipole is connected to a parallel stripline printed on the front and back sides of the substrate. The metasurface, which is made up of a circular patch with 2 × 2 center patches that have a different radius than the outer patches, and the cross-slots of unequal lengths are used for the polarization conversion of a linearly polarized wave to a circularly polarized wave. The measured reflection coefficients for |S11| < -10 dB yielded an impedance bandwidth of 25.6–31.8 GHz (21.5%), a 3-dB axial ratio (AR) bandwidth of 26.1–30.5 GHz (15.5%), a 3-dB gain bandwidth of 26.0–31.1 GHz (17.4%) with a peak gain of 11.0 dBic, and a radiation efficiency of more than 80% in the axial ratio bandwidth.
Deep Neural Network for the Behavioral Modeling of Memory Effects and Supply Dependency on 10-W Nonlinear Power Amplifiers

In this paper, a deep neural network (DNN) model is proposed for the behavioral modeling of nonlinear power amplifiers with supply dependency. Although the conventional nonlinear model, such as the Volterra series, has high accuracy, it is not commonly implemented because of its complexity. However, with manageable complexity, the multidimensional input parameters of the proposed model ensure the modeling of the nonlinear behavior of power amplifiers with supply voltage dependency. The proposed model is trained by multi-tone signals on a 10-W power amplifier and validated by comparing the output spectrum and the third-order intermodulation (IMD3) of the model versus the measured data. The output spectrum shows less than 0.38 dB of error over a bandwidth of 10 MHz and input power from 11 dBm to 17 dBm, and the IMD3 error is less than 0.1 dB over the output power range.

The article presents the results of an empirical study in the features of the bodily sensations categorization associated with the disease in patients suffering from multiple sclerosis of varying degrees of disability. Using the psychosemantic technique “Choice of descriptors of intraceptive sensations” by A.Sh. Tkhostov, the peculiarities of verbalization, interpretation and categorization of intraceptive (internal bodily) sensations used by patients to describe their complaints were revealed. The sample consisted of 76 patients with multiple sclerosis, aged from 21 to 60 years (µ = 35.3, σ = 8,6), the duration of the disease from 1 to 33 years (µ = 4,4, σ = 5). Methods of descriptive statistics, frequency analysis and the nonparametric Kraskel-Wallis criterion were used to compare groups of patients with different disability rating (according to EDSS). There were no differences in the volumes of descriptor dictionaries used to describe the bodily experience of the disease in patients with different duration of the disease, since multiple sclerosis does not have a linear development and each patient goes through his own unique path in the process of nosognosy. Statistically significant differences were found in the volumes of dictionaries of intraceptive sensations (associated with the disease, dangerous and often experienced) in patients with varying degrees of disability rating (according to EDSS). It is shown that the most extensive dictionaries of intraceptive sensations associated with the disease are in patients with average disability rating. That group has already had some adaptation to the fact of the disease, but due to the diversity of its manifestations and the unpredictability of their appearance, patients tend to attribute any bodily sensations to the disease. In more severe patients, there is a reduction of dictionaries describing the bodily experience of the disease. The most commonly used words in all groups of patients are those describing feelings of loss of tone, strength and sensitivity. Taking into account the peculiarities of nosognosia is necessary when building psychoprophylactic programs with patients suffering from multiple sclerosis
