Published: August 2023

Zinc oxide nanowires (ZnO NWs) have gained considerable attention in the field of piezoelectricity in the past two decades. However, the impact of growth-process conditions on their dimensions and polarity, as well as the piezoelectric properties, has not been fully explored, specifically when using pulsed-liquid injection metal–organic chemical vapor deposition (PLI-MOCVD). In this study, we investigate the influence of the O2 gas and DEZn solution flow rates on the formation process of ZnO NWs and their related piezoelectric properties. While the length and diameter of ZnO NWs were varied by adjusting the flow-rate conditions through different growth regimes limited either by the O2 gas or DEZn reactants, their polarity was consistently Zn-polar, as revealed by piezoresponse force microscopy. Moreover, the piezoelectric coefficient of ZnO NWs exhibits a strong correlation with their length and diameter. The highest mean piezoelectric coefficient of 3.7 pm/V was measured on the ZnO NW array with the length above 800 nm and the diameter below 65 nm. These results demonstrate the ability of the PLI-MOCVD system to modify the dimensions of ZnO NWs, as well as their piezoelectric properties.

To promote the rational use of Inonotus obliquus (chaga) from Eastern Canada, a mushroom consumed in infusion as a health drink, the extraction of its constituents was investigated. The extraction was carried out with water or ethanol at room temperature or by heating as well as following exposure to ultrasound. The extracts of the four seasons obtained with the four extraction methods were compared for their contents in carbon, nitrogen (N), sulfur (S), potassium (K), betulin, betulinic acid, potassium, flavonoids, and polyphenols. The antiradical effect as well as the photoprotective effects of all extracts were also investigated. The results show that there is no difference between the quantities extracted from the extracts of the 4 seasons. The results show a significant difference between the mass of the extracts obtained with water and ethanol. Betulinic acid was found to be more abundant in the extracts obtained with water while betulin was more abundant in the extracts obtained with ethanol. The mushroom and the extracts had high C contents, but low N and S contents, typical of protein-poor and carbohydrate-rich materials. Extracts were particularly rich in potassium, five times more than bananas. Heating favors the extraction of polyphenols and flavonoids. The aqueous extracts of chaga harvested in winter had the highest antiradical capacity. With a Sun Protection Factor (SPF) higher than 30 in the UVB wavelength, chaga extracts might be used as sunscreen. Extracts obtained with water had the highest SPF in general. The analysis of this mushroom further highlights this local product that deserves more attention for its potential benefits as a functional food/nutraceutical product. In addition to its nutritional values, this mushroom can also be used for its cosmetic qualities as it can be used as a sunscreen.
Pathophysiology of Red Blood Cell Dysfunction in Diabetes and Its Complications

Published: August 2023

Diabetes Mellitus (DM) is a complex metabolic disorder associated with multiple microvascular complications leading to nephropathy, retinopathy, and neuropathy. Mounting evidence suggests that red blood cell (RBC) alterations are both a cause and consequence of disturbances related to DM-associated complications. Importantly, a significant proportion of DM patients develop varying degrees of anemia of confounding etiology, leading to increased morbidity. In chronic hyperglycemia, RBCs display morphological, enzymatic, and biophysical changes, which in turn prime them for swift phagocytic clearance from circulation. A multitude of endogenous factors, such as oxidative and dicarbonyl stress, uremic toxins, extracellular hypertonicity, sorbitol accumulation, and deranged nitric oxide metabolism, have been implicated in pathological RBC changes in DM. This review collates clinical laboratory findings of changes in hematology indices in DM patients and discusses recent reports on the putative mechanisms underpinning shortened RBC survival and disturbed cell membrane architecture within the diabetic milieu. Specifically, RBC cell death signaling, RBC metabolism, procoagulant RBC phenotype, RBC-triggered endothelial cell dysfunction, and changes in RBC deformability and aggregation in the context of DM are discussed. Understanding the mechanisms of RBC alterations in DM provides valuable insights into the clinical significance of the crosstalk between RBCs and microangiopathy in DM.
Optimization of Longitudinal Alignment of an 4f System in a Compact Vectorial Optical-Field Generator Based on a High-Resolution Liquid Crystal Spatial Light Modulator
Authors: Li Mingyu , Liu Yuanzheng
Published: August 2023

Vectorial optical fields have garnered significant attention due to their potential applications in areas such as optical nano-fabrication, optical micromachining, quantum information processing, optical imaging, and so on. Traditional compact vectorial optical generators with amplitude modulation perform poorly in terms of diffraction effect reduction. To tackle this problem, the refractive 4f system in amplitude modulation is longitudinally aligned using an optimization approach presented in this research. The phase images used for longitudinal alignment are loaded into the liquid crystal spatial light modulator (SLM), and the distance between the lens and the mirror in the reflective 4f system is adjusted for longitudinal alignment by compensating for the neglected phase in the integrated module for the compact vectorial optical-field generator. The spot images collected by the CCD are processed using the improved eight-direction Sobel operator and Roberts function, and the longitudinal alignment in the reflective 4f system is determined by the sharpness of the image. The sharpness of the edges of the lines and the overall image are both enhanced after optimization compared to before optimization. The results demonstrate that the proposed method can effectively reduce the longitudinal alignment error of the reflective 4f system in the amplitude modulation of the compact vectorial optical-field generator, lessen the diffraction effect, and improve the performance of the system.

Published: August 2023

The aim of this study was to evaluate and compare the stress concentration of short dental implants supporting different conical abutments using 3D finite element analysis (3D-FEA). A tridimensional model of single-unit short dental implants (5.2 mm × 5 mm) was designed using the computer-aided design (CAD) software based on the manufacturer’s stereolithography. The short implants were positioned in a bone model to support titanium or ceramic-reinforced PEEK conical abutments considering different bone levels (supra-crestal, crestal or sub-crestal). With the aid of a computer-aided engineering (CAE) software, the finite element model was created and an axial load of 500 N was applied. Observing the mechanical response of the implant, abutment and screw, both evaluated materials resulted in homogeneous stress and could be indicated for implant-supported restorations with short fixtures. However, aiming to decrease the strain in the bone tissue, placing the implant in the sub-crestal position is a preferable option; while the supra-crestal placement decreases the stress at the screw and implant.
Six Decades of Dopamine Hypothesis: Is Aryl Hydrocarbon Receptor the New D2?
Authors: Sfera Adonis
Published: August 2023

In 1957, Arvid Carlsson discovered that dopamine, at the time believed to be nothing more than a norepinephrine precursor, was a brain neurotransmitter in and of itself. By 1963, postsynaptic dopamine blockade had become the cornerstone of psychiatric treatment as it appeared to have deciphered the “chlorpromazine enigma”, a 1950s term, denoting the action mechanism of antipsychotic drugs. The same year, Carlsson and Lindqvist launched the dopamine hypothesis of schizophrenia, ushering in the era of psychopharmacology. At present, six decades later, although watered down by three consecutive revisions, the dopamine model remains in vogue. The latest emendation of this paradigm proposes that “environmental and genetic factors” converge on the dopaminergic pathways, upregulating postsynaptic transmission. Aryl hydrocarbon receptors, expressed by the gut and blood–brain barrier, respond to a variety of endogenous and exogenous ligands, including dopamine, probably participating in interoceptive awareness, a feed-back loop, conveying intestinal barrier status to the insular cortex. The conceptualization of aryl hydrocarbon receptor as a bridge, connecting vagal terminals with the microbiome, may elucidate the aspects of schizophrenia seemingly incongruous with the dopamine hypothesis, such as increased prevalence in urban areas, distance from the equator, autoantibodies, or comorbidity with inflammatory bowel disease and human immunodeficiency 1 virus. In this review article, after a short discussion of schizophrenia outcome studies and insight, we take a closer look at the action mechanism of antipsychotic drugs, attempting to answer the question: do these agents exert their beneficial effects via both dopaminergic and nondopaminergic mechanisms? Finally, we discuss potential new therapies, including transcutaneous vagal stimulation, aryl hydrocarbon receptor ligands, and restoring the homeostasis of the gut barrier.

Published: August 2023

In miniaturized affinity chromatography, the development of hydrophilic organic monoliths with reduced non-specific interactions and high-protein grafting capacity remains a hot topic. In this work, we propose the one-step synthesis of a diol organic monolith to replace the gold-standard epoxy-based organic monoliths (which require post-modification, namely hydrolysis, prior to use). The synthesis of this new monolith builds upon the use of N-N’-Methylenebis(acrylamide) (MBA), as a hydrophilic crosslinker, and 2,3-dihydroxypropyl methacrylate (DHPMA), a diol monomer that eliminates the time-consuming epoxy ring opening step and its associated side reactions. The optimization of one-step synthesis parameters led to a monolith with a satisfactory permeability ((4.8 ± 0.5) × 10−14 m2), high efficiency (117,600 plates/m at optimum flow velocity (uopt = 0.09 cm s−1)) and reduced non-specific interactions. It is exemplified by its separation ability in the HILIC mode (separation of nucleosides), and by the retention data set of 41 test solutes, which were used to evaluate the non-specific interactions. This new poly(DHPMA-co-MBA) monolith has not only hydrophilic surface properties, but also improved protein grafting capacity compared to the glycidyl-based monolith (13 ± 0.7 pmol cm−1). The potential of this monolith is illustrated in affinity chromatography, where the concanavalin ligands are ranked according to their Kd values.

Published: August 2023

In this work, the Pb adsorption and removal ability of biochar from simulated Pb(II)-contaminated wastewater, adsorption isotherms, kinetics, and thermodynamics were studied. Adsorption characteristics of biochar on Pb(II) were analyzed by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning electron microscope with energy dispersive spectrometer (SEM-EDS). The influence of the pH of the solution, the contact time, and the biochar dose on the removal of Pb(II) were investigated by single-factor design and response surface analysis. With the increase in biochar dose from 2 g/L to 4 g/L in wastewater, the Pb(II) amount adsorbed on biochar reduced from 21.3 mg/g to 17.5 mg/g. A weakly acidic environment was more conducive to the ligand exchange between Pb(II) ions and biochar. Pb(II) adsorption kinetics of biochar showed that the Pseudo-first-order model was more suitable than other employed models to describe the adsorption process. During the isothermal adsorption process, Langmuir and Freundlich’s isotherms fitted the adsorption data very well (R2 > 96%). The Pb (II) adsorption onto biochar was spontaneous in the specified temperature range (298–318 K) and the process was exothermic. Simultaneously, the optimal conditions were a pH of 5, a contact time of 255 min, and a biochar dose of 3 g/L, under which the maximum predicted Pb(II) removal efficiency was 91.52%.
A Nonlinear Optimization Design Algorithm for Nearly Linear-Phase 2D IIR Digital Filters
Authors: Omar Abdussalam , Shpak Dale , Agathoklis Panajotis , Moa Belaid
Published: August 2023

In this paper, a new optimization method for the design of nearly linear-phase two-dimensional infinite impulse (2D IIR) digital filters with a separable denominator is proposed. A design framework for 2D IIR digital filters is formulated as a nonlinear constrained optimization problem where the group delay deviation in the passband is minimized under prescribed soft magnitude constraints and hard stability requirements. To achieve this goal, sub-level sets of the group delay deviations are utilized to generate a sequence of filters, from which the one with the best performance is selected. The quality of the obtained filter is evaluated using three quality factors, namely, the passband magnitude quality factor Qh and the group delay deviation quality factor Qτ, while the third one is a new quality factor Qs that assesses the performance in the stopband relative to the minimum filter gain in the passband. The proposed framework is implemented using the interior-point (IP) method in a MATLAB environment, and the experimental results show that filters designed using the proposed method have good magnitude response and low group delay deviation. The performance of the resulting filters is compared with the results of other methods.
Mirroring Truths: How Liberal Democracies Are Challenging Their Foundational Narratives
Authors: Fernandez-Torne Carles , Young Graeme
Published: August 2023

Long-established liberal democracies with histories of settler colonialism—from the United States and Canada to Australia and Scandinavia—are beginning to explore their histories of violence and dispossession. This, in many ways, is long overdue, but the desire to come to terms with past injustices should not obscure the challenges that still stand in the way of any reasonable effort to do so. We argue that transitional justice can be applied to colonial history in liberal democracies, but there are major conceptual and practical obstacles that need to be overcome if this is to happen in meaningful ways. We explore three of these obstacles here that are particularly significant: the doctrine of intertemporal law, the unequal power balance between the Global North and the Global South, and national identity. If these are to be overcome, it is important to tie historical to present injustices and to incorporate, beyond violations of physical rights, violations of economic and social rights that are particularly relevant for understanding continuities between past and ongoing violations. These rights are commonly neglected even by states that recognize a broad set of liberal rights and have the capacity to ensure that they are realized, and represent a promising avenue for pursuing a truly inclusive, equitable, and universal understanding of justice.

Authors: Alarifi Abdullah M. , Alshahrani Najim Z. , Sah Ranjit
Published: August 2023

Since Saudi Arabia has already confirmed multiple monkeypox (Mpox) cases, it is essential to initiate timely preventive measures, including the implementation of vaccines. In this cross-sectional study, an online survey was conducted among healthcare workers (HCWs) in Saudi Arabia to understand their willingness to receive the Mpox vaccine. A structured questionnaire was used to gather the data. The study comprised 734 samples. Our study found that among study participants, 52.7% were willing to receive the Mpox vaccine and showed that sociodemographic factors were not significantly associated with vaccine willingness. Previous vaccination history (such as influenza and COVID-19) was significantly associated with Mpox vaccine willingness. The respondents reported that the main reasons for receiving the Mpox vaccine were their trust in the Saudi Health Ministry (57.7%) and their understanding that the vaccine was a social responsibility (44.6%). Furthermore, the majority of the respondents (74.7%) reported that they were motivated by the need to protect themselves, their family and their friends. Insufficient vaccine information and fear of unknown adverse reactions were the most reported reasons for an unwillingness to receive the Mpox vaccine. In conclusion, increasing Mpox vaccine-related awareness and focusing on greater information dissemination to reduce fear and increase vaccine uptake is highly recommended.

Published: August 2023

Carbon neutrality is a key human endeavor to deal with global climate while China is the country producing the most publications on carbon neutrality. However, what are the focuses of carbon-neutrality research in China? To answer such an important question, this study adopts a bibliometric approach to analyze carbon-neutrality journal publications from China-based researchers during the period of 2008–2022 using CNKI and Scopus. Results showed that carbon-neutrality publications in Chinese and English journals by Chinese-based researchers increased from 4 in 2008 to 2879 in 2022. In Chinese journals, X.D. Hao was the most productive author with 10 publications. In English journals, Y.K. Zhou was the most productive author with 14 publications. As a whole, the Chinese Academy of Sciences was the most productive institution with 376 publications. Co-occurrence of keywords analysis revealed seven themes in Chinese journal articles, namely, “carbon neutrality and climate change”, “energy transformation”, “peak carbon emission”, “carbon emission and low carbon economy”, “realization path in China”, “hydrogen energy and clean energy”, and “green finance and sustainable development”. In English journals, three major clusters were formed—“carbon, carbon neutralities, emission control, and energy utilization”, “carbon dioxide, carbon neutrals, biomass, and electrocatalysts”, and “China, carbon neutrality, sustainable development, and economic development.” Most extant publications focused on policy and technological development. Emphasis shall be paid to social change and changes in people’s behavior, sectoral carbon emissions, and carbon leakage in future research.

The recent study aimed to evaluate the knowledge levels of dentists on intraoral scanners and 3D printers with their usage prevalence of them in Türkiye.A link to the survey was sent via e-mail to 1782 dentists in different branches who participated in this survey, which had 27 questions in four subgroups, including demographic information, general digital dentistry, intraoral scanners, and 3D printers. The total number of dentists who answered the questionnaire was determined as 305. Considering the distribution of the ages, %21.3 (n=65) of the participants were 23-28 years, %32.1 (n=98) were 29-35 years, and %46.6 (n=142) were 36 and over years. A statistically significant difference was found in the use of intraoral scanners and 3D printers in workplaces (p<0.001, p<0.001). A statistically significant difference was found regarding branches in intraoral scanner usage. While the rate of using intraoral scanners by 54.5% of restorative dentists is higher than other branches (p<0.001), orthodontists were found to be more active users of 3D printers (47.9%, p=0.001). According to the results of our study, it has been observed that dentists generally obtain information about intraoral scanners and 3D printers through individual efforts and only a few dentists in Türkiye can integrate these devices into their everyday practices.
THE RELATIONSHIP BETWEEN FOOD INSECURITY AND OBESITY IN UNIVERSITY EMPLOYEES: A CROSS-SECTIONAL STUDY
Authors: BAL Simge , OKAN BAKIR Binnur
Published: August 2023

Food insecurity is the lack of availability or access to safe and healthy food due to limited resources and is a nutritional factor associated with obesity. We aimed to evaluate the relationship between food insecurity and obesity in university employees. This study was conducted among 142 administrative employees of a private university between January 2020 and October 2020. Data was collected with Household Food Security Survey Module-Short Form (HFSSM-SF), and anthropometric measurements and socio-demographic characteristics were recorded. Of the participants 39.4% were overweight, and 21.8% were obese. 64.1% of the individuals were food secure, and 35.9% were food insecure. There was no statistically significant relationship between body mass index (BMI) classes or waist circumference (WC) categories and both food accessibility levels and food security status (p>0.05). A weak significant positive relationship existed between the BMI (kg/m2) and HFFSM-SF scores (r=0.219,p=0.009). As the risk of inaccessibility of food increased, the BMI of the participants increased. According to the data collected with the HFSSM-SF, it has been determined approximately one-third of the employees experience food insecurity. It is crucial to develop policies that will contribute to preventing food insecurity with the necessary investigations and future studies.

The data were analyzed by following Collazzi's seven-stage method.11 sub-themes and 3 themes were created: difficulties experienced during the pandemic period, emotions experienced during the pandemic period, and coping strategies during the pandemic period. It has been shown that These caregivers, who have a high burden of care even in normal times, faced many difficulties and were negatively affected emotionally due to the surgery of their patients during the pandemic period. The nurse should know the daily life, social supports, social conditions, and ways of coping with the problems of the caregiver of the elderly person with Alzheimer's disease and related dementia. If caregivers' experiences, social supports, social conditions, and ways of coping with the problems and difficulties are known, home care strategies can be developed to manage these difficulties.

Published: August 2023

This study aimed to determine the relationship between cancer information overload and attitudes toward cancer screening in elderly patients who underwent surgery. A total of 123 geriatric individuals participated in the cross-sectional study. The mean age of the participants in the study was 70.63±5.81. It was determined that 17.1% of the individuals had cancer, 30.9% had cancer in their first degree relatives, 52% had cancer screening before, and the most common screenings were colonoscopy (23.6%), pap smear (14.6%), and breast self-examination (8.1%). It was determined that the total score averages of the attitude scale for cancer screening of those who obtained information about cancer from the internet/media were significantly lower (p=0.030). It was determined that there was a significant moderate negative correlation between cancer information overload and the total scores of the attitude scale for cancer screening (r=-0.303, p=0.001). To encourage screening in the geriatric population and to prevent the risks of unnecessary screening, arrangements should be made to facilitate access to accurate information.

A energia elétrica é um dos recursos cruciais à sobrevivência da sociedade moderna, pois não nos imaginamos mais sem ela, mas também sabemos que não é um recurso infinito, logo, temos que inovar e fazermos o uso consciente deste recurso. Essa reinvenção passa pela reeducação das pessoas em relação ao uso mais consciente e eficiente. Atualmente, a energia elétrica é necessária em praticamente todas as atividades humana desde o simples ato de tomar banho passando pela conservação de nossos alimentos, até a iluminação pública para melhor convivência em sociedade, além de nos proporcionar conforto e segurança. Com a conscientização de todos podemos então, fazer uso mais racional de tal recurso, pois manteremos os aparelhos eletrônicos em funcionamento por mais tempo, tendo em vista que a energia será utilizada de melhor forma e com o mínimo de desperdício. Isso implicaria em menor impacto ao meio ambiente em função da construção de menos represas e consequentemente menos áreas inundadas, pois as formas de geração apesar de vir migrando para fontes alternativas ainda têm quase 70% de geração hidráulica. Assim sendo devemos adotar atitudes mais eficientes que levará à economia, como a simples ação de desligar os aparelhos da tomada, quando não estiverem em uso evitando que os mesmos fiquem em modo stand by, substituição das atuais lâmpadas fluorescentes e econômicas por lâmpadas a LED (light emitting diode) ou diodo emissor de luz, etc., representando apenas algumas ações eficazes para um melhor aproveitamento e consequente diminuição do consumo da energia elétrica, mas para isso precisaremos da conscientização e colaboração de todos, pois a classe residencial representa a segunda maior em termos de consumo.

En este trabajo se obtuvieron membranas sulfonadas a partir de la copolimerización radicalaria al azar del MMA y del SPMAK para su potencial uso como membranas de intercambio protónico. Se emplearon cuatro relaciones molares diferentes entre el MMA y el SPMAK para estudiar el efecto del grado de sulfonación en sus propiedades fisicoquímicas. Se usó el análisis de FTIR para identificar los grupos químicos funcionales presentes en la estructura de las membranas, se obtuvo la temperatura de transición vítrea (Tg) por calorimetría diferencial de barrido (DSC); además, se determinó la capacidad de absorción de agua y el ángulo de contacto con el agua. Finalmente, la capacidad de intercambio iónico y propiedades de transporte de iones fueron evaluadas. Este conjunto de propiedades fisicoquímicas permite considerar a las membranas obtenidas con un alto potencial de aplicación en celdas de combustibles, tratamiento de agua y aplicaciones relacionadas con el transporte de protones. Se identificó una banda de absorción a 1726 cm-1 asignada al estiramiento C=O que pertenece al éster y la banda 2935 cm-1 debido al estiramiento del –CH2–, que son bandas características para PMMA, de igual manera, se identificaron las bandas en 1180 cm-1 y 1045 cm-1 las cuales se asignaron al enlace O=S=O, asociadas a la presencia de grupo sulfónico. Se observó una disminución de la Tg de los copolímeros conforme aumentaba el contenido de SPMAK y al mismo tiempo se observó un aumento en la absorción de agua. En este sentido los ángulos de contacto obtenidos, para PMMA fue de 72°, disminuyendo conforme la composición de SPMAK aumentaba así; en el copolímero 88.5:11.5 %MMA/SPMAK se obtuvo un ángulo de contacto de 41° y para el de 78.5:21.5% fue de 0°. Los copolímeros aleatorios SPMAK-11.5 y SPMAK-21.5 mostraron un aumento en la IEC con respecto al homopolímero de PMMA, presentando valores de 0.1948, 0.4316 y 0.9784 mmol g-1, con una tendencia casi lineal en el incremento de la composición del monómero sulfonado. La permeabilidad y el flujo iónico para el copolímero SPMAK-11.5 son de 95 % y 4.2586 m/s, respectivamente, mayores al PMMA.

El efecto de la innovación y registros de los productos en las empresas es lo que las hace ser competitivas. En Bimbo Chihuahua, se realizó la presente investigación con el objetivo de identificar las deficiencias en la innovación y registro de productos para saber en qué se está fallando y en que se puede mejorar estos procesos. La investigación fue de naturaleza cuantitativa, con apoyo bibliográfico. La investigación es con base a criterios metodológicos, con la información que se brindó por el personal encargado de ventas. Con los datos obtenidos por los 60 empleados se analizaron las variables de estudio, así como también la estructura en la que se relacionan, con base a esto se obtuvieron las conclusiones y recomendaciones. Se trabajó directamente con el personal involucrado en ventas, donde se elaboró un cuestionario basado en 20 preguntas con observación participativa y así poder confirmar la información recabada. En los resultados se muestra que la empresa cuida sus productos, sin embargo, es necesario poner más atención en este punto a corto plazo para evitar el riesgo de robo de ideas en productos que se encuentren en el proceso de innovación.
