ALAT PENYORTIR WARNA DAUN TEH MENGGUNAKAN SENSOR TCS3200 BERBASIS RASPBERRY PI DAN ARDUINO
Authors: Sari Yunita , Meisari Sri Wulan
Published: May 2023

Kualitas teh dapat ditentukan dari daun teh yang dipetik, dimana semakin muda daun teh maka mutu

yang dihasilkan semakin baik, begitu pula sebaliknya. Perbedaan umur daun teh ini juga menentukan

kandungan senyawa polifenol pada daun teh yang akan berpengaruh pada rasa, aroma, dan warna.

Identifikasi dan pengendalian mutu teh sebagai bahan utama suatu produk merupakan syarat utama

agar dihasilkan produk yang berkualitas baik. Oleh karena itu dibutuhkanlah kualitas daun teh yang

bagus untuk menghasilkan daun teh. Sistem penyortiran warna daun teh yang saat ini terjadi masih

bersifat manual menimbulkan masalah dalam kualitas daun teh. Dari permasalahan tersebut

dirancanglah alat untuk mensortir daun teh yang dapat memilih daun teh yang bagus sesuai dengan

warnanya. Pada penelitian ini digunakan 6 (enam) komponen utama untuk perancangan alat Sensor

TCS3200, Raspberry pi 3, mikrokontroler arduino, Driver Motor L298N, Buzzer, LCD. Semua

komponen tersebut dirangkai dan diprogram agar bisa melakukan sortir daun teh yang bagus

berdasarkan warna daunnya yang kemudian data hasil sortir akan tersimpan kedalam Log

penyortiran warna daun teh.

CO2 electro/photocatalytic reduction using nanostructured ZnO and silicon-based materials: A short review
Authors: Galdámez-Martínez Andrés , Dutt Ateet
Published: May 2023

Reducing CO2 net emissions is one of the most pressing goals in tackling the current global warming emergency. Therefore, the development of carbon recycling strategies has resulted in the application of heterogeneous catalysts toward the electro/photocatalysis reduction of CO2 into hydrocarbons with potential reusability. Their morphology is among the properties that affect the performance and selectivity of catalysts towards this reaction. Nanostructuring methods offer popular strategies for catalytic applications since they allow an increase in the area/volume ratio and versatile control over surface physicochemical properties. In this review, we summarize studies that report the use of versatile synthesis techniques for obtaining nanostructured metallic and semiconductor materials with application in the electro/photocatalytic reduction of CO2. Enhancing mechanisms to the catalytic CO2 reduction yield, such as improved charge carrier separation efficiency, defect engineering, active site concentration, and localized plasmonic behavior, are described in conjunction with the control over the morphologies of the nanostructured platforms. Special attention is given to ZnO and silicon-based matrices as candidates for developing abundant and non-toxic catalytic materials. Therefore, this work represents a guide to the efforts made to design electro/photocatalytic systems that can contribute significantly to this field.

Delirium is a frequent cause of decompensation in the elderly, especially with higher prevalence in highly dependent patients, in advanced ages and senile dementia. It is important to always look for the principal cause before treating only the symptom. This case describes a 79-year-old woman with an episode of agitation and disorientation lasting several days, underestimated by its mild nature, but which ends up being a thalamic hemorrhagic stroke. Hemorrhagic stroke is a less common pathology than ischemic stroke but with higher morbidity and mortality. Specifically focused on the thalamus produces behavioral and sensory alterations that can be confused with multiple pathologies. Early identification and approach influence recovery and the sequelae that are being worked with different physiotherapeutic therapies.

Using digital technologies in the stock market: The criminal law aspect
Authors: Komova E. Yu. , Sidorenko E. L.
Published: May 2023

Under sanctions, digital services and products that are not affected by restrictions are of particular interest to unqualified investors of the Russian stock market. The possibility of illegal use of digital technologies in the stock market has not gone unnoticed by people with criminal intent. This article analyzes the already existing illegal practices in the stock market of using digital technologies and services, and also identifies criminal legal risks of their potential development in the future. The authors use general scientific methods of research as synthesis, analysis, induction, deduction, classification, as well as special methods (systematical, structural and dogmatical, as well as content analysis methods) based on a wide range of judicial practice. As a result, the authors formulate the following main areas of using digital technologies in the stock market for criminal purposes: 1) obtaining unauthorized access to users’ personal accounts; 2) organizing the activities of financial pyramids and illegal forex dealers; 3) fraudulent activity through the marketing of financial services by illegal financial market participants; 4) using artificial intelligence for the purposes of false trading. It has been established that the measures currently taken by supervisory and law enforcement agencies are not sufficient to protect unqualified investors from the criminal actions of malefactors. At the same time, the need to strengthen control over the use of digital technologies will require finding a balance between minimizing risks by government agencies and continuing to actively use new technologies on the Russian stock market.

GAINERS AND LOSERS OF EURO ADOPTION: THE CASE OF THE BALTIC STATES
Authors: Petrylė Vaiva , Bunevičiūtė Karolina
Published: May 2023

In this paper we analyse the effects of the adoption of euro on the economies of the three Baltic countries. We employ the difference-in-differences approach to estimate the impact of the currency changeover on the product prices in the Baltic states. We also examine which specific demographic groups of consumers (by their age, education and income levels) were the most sensitive for the currency changeover. Our results suggest that the greatest euro-related price increase in the Baltic countries was related to the products belonging to the 4th and the 5th price quantiles, especially services. We also find that in the Baltic countries consumers groups which reacted to the adoption of euro the most sensitively were better educated people between 30 and 49 years. However, the impact of currency changeover for the consumers seems to be country specific.
MESOCLIMATIC ANALYSIS OF NON-PRECIPITATION PERIODS IN LITHUANIA
Authors: Ūselytė Joana , Bukantis Arūnas
Published: May 2023

In this paper, climatic analysis of non-precipitation periods (NPP) in Lithuania was performed, assessing their recurrence and trends from 1991 to 2020 using two criteria – when precipitation was <0.1 mm per day all year round and when precipitation was <1 mm per day during the warm period – and analysing typical atmospheric circulation in the middle troposphere and sea level during the longest NPP (≥20 days). From 1990 to 2020, NPP were most frequent in the Middle Lithuania lowland (according to both criteria), in Southern and South-western Lithuania (daily precipitation <0.1 mm) and in part of Eastern Lithuania (daily precipitation <1 mm), and least frequent in part of the Samogitian highland and in part of the Baltic Highlands (according to both criteria). NPP recurred most often in the spring months, as this is associated with a higher number of days with anticyclonic circulation and powerful anticyclones recorded. Based on the growth trend of NPP of various durations in Lithuania from 1990 to 2020, in the last decade NPP have become more frequent, but only a few stations have shown reliable trends. Analysis of the atmospheric circulation during the longest NPP (≥20 days) showed that NPP were mostly determined by the Azores anticyclone ridge or anticyclone over Northern, Central or Eastern Europe regardless of the time of year. The atmospheric circulation conditions for the formation of long NPP varied more in the cold period than in the warm period, but NPP often lasted ≥20 days only at one or a few stations.
A Chandra X-Ray Survey of Optically Selected Close Galaxy Pairs: Unexpectedly Low Occupation of Active Galactic Nuclei
Authors: He Lin , Hou Meicun , Li Zhiyuan , Feng Shuai , Liu Xin
Published: May 2023

High-resolution X-ray observations offer a unique tool for probing the still-elusive connection between galaxy mergers and active galactic nuclei (AGNs). We present an analysis of nuclear X-ray emission in an optically selected sample of 92 close galaxy pairs (with projected separations ≲20 kpc and line-of-sight velocity offsets <500 km s−1) at low redshift (

z

), based on archival Chandra observations. The parent sample of galaxy pairs is constructed without imposing an optical classification of nuclear activity, thus it is largely free of selection effect for or against the presence of an AGN. Nor is this sample biased for or against gas-rich mergers. An X-ray source is detected in 70 of the 184 nuclei, giving a detection rate of

, down to a 0.5–8 keV limiting luminosity of ≲1040 erg s−1. The detected and undetected nuclei show no systematic difference in their host galaxy properties such as galaxy morphology, stellar mass, and stellar velocity dispersion. When potential contamination from star formation is avoided (i.e., L
2−10 keV > 1041 erg s−1), the detection rate becomes

Moreover, most nuclei at the smallest projected separations probed by our sample (a few kiloparsecs) have an unexpectedly low apparent X-ray luminosity and Eddington ratio, which cannot be solely explained by circumnuclear obscuration. These findings suggest that close galaxy interaction is not a sufficient condition for triggering a high level of AGN activity.
Molecular species delimitation and description of a new species of Phenacogaster (Teleostei, Characidae) from the southern Amazon basin
Authors: Souza Camila S. , Mattox George M. T. , Vita George , Ochoa Luz E. , Melo Bruno F. , Oliveira Claudio
Published: May 2023

Phenacogaster is the most species-rich genus of the subfamily Characinae with 23 valid species broadly distributed in riverine systems of South America. Despite the taxonomic diversity of the genus, little has been advanced about its molecular diversity. A recent molecular phylogeny indicated the presence of undescribed species within Phenacogaster that is formally described here. We sampled 73 specimens of Phenacogaster and sequenced the mitochondrial cytochrome c oxidase subunit I (COI) gene in order to undertake species delimitation analyses and evaluate their intra- and interspecific genetic diversity. The results show the presence of 14 species, 13 of which are valid and one undescribed. The new species is known from the tributaries of the Xingu basin, the Rio das Mortes of the Araguaia basin, and the Rio Teles Pires of the Tapajós basin. It is distinguished by the incomplete lateral line, position of the humeral blotch near the pseudotympanum, and shape of the caudal-peduncle blotch. Meristic data and genetic differentiation relative to other Phenacogaster species represent strong evidence for the recognition of the new species and highlight the occurrence of an additional lineage of P. franciscoensis.
Touch: changing norms of physical contact between men and women in 18 th century England
Authors: Philp Mark
Published: May 2023

Résumé Cet article examine l’évolution des normes concernant le toucher, en particulier entre les jeunes femmes en âge de se marier et les jeunes hommes en Grande-Bretagne à la fin du 18 e  siècle. Ces normes émergentes, liées à la sociabilité et aux idéaux de la société polie, ont été largement contrôlées par d’autres femmes. Bien qu’elles leur aient permis une certaine liberté par rapport aux tentatives intrusives des hommes, ces normes s’accompagnent également d’un déni du désir sexuel des femmes. Les personnes considérées comme transgressant ces normes risquent d’être exclues de la « société ». La discussion s’appuie sur une série de mémoires, de journaux intimes, de romans, de livres de conduite et de lettres pour examiner un domaine de conduite qui fait rarement l’objet de commentaires explicites.
Le statut civil et politique des femmes chez Montesquieu
Authors: Radica Gabrielle
Published: May 2023

Montesquieu élucide le statut des femmes à travers la connaissance des mœurs, la critique de la vie domestique, et l’évaluation juridique (soit : sociologie, morale et droit). Distinguer les femmes comme individus (membres d’une famille, sujets de droit), des femmes entendues comme classe, groupe social plus ou moins unifié, permet tout d'abord de séparer les problèmes. En outre, le contraste entre harems et familles harmonieuses révèle combien le bonheur de tous les membres des familles, hommes comme femmes, dépend des ressorts domestiques de la tendresse ou de la liberté, bien supérieurs à celui de la crainte. Enfin, l’auteur montre à quel point l’assise et le rôle des femmes dans leur famille dépendent de la qualité de leur accès aux biens et du régime juridique auquel elles sont soumises. C’est le droit civil en effet qui fait des femmes tantôt les propriétés des maris, tantôt des propriétaires sous leur tutelle, tantôt enfin des propriétaires à plein titre.
Le pouvoir de l’amitié pour saisir un phénomène « météorologique » exceptionnel. Informateurs et observateurs des globes de feu de 1676 et 1784
Authors: Dolet Simon
Published: May 2023

Les globes de feu demeurent des phénomènes incompris jusqu’en 1794, lorsque Chaldni annonce leur nature extraterrestre. Jusque-là traités comme des météores, ils entraient dans le champ de la météorologie naissante. En s’intéressant à Montanari et à Toaldo, deux savants italiens, la lente construction de ce savoir apparaît dans sa distanciation avec Aristote et sa relation avec les croyances populaires. Elle repose sur la contribution d’informateurs et d’observateurs, recrutés dans des réseaux personnels, régionaux et locaux. Moins considérés que les réseaux supranationaux, ils démontrent pourtant un pan de la construction de la science météorologique, animé par l’amitié.

Dans l’œil du viseur : vision armée, images opératoires et contre-visualités
Authors: Fourmentraux Jean-Paul
Published: May 2023

À l’ère numérique, l’acte de voir n’a peut-être jamais été autant articulé à une soumission aveugle aux machines. Dans le cas des drones et des « images opératoires » à l’œuvre dans les conflits armés, ce premier couplage du regard aux machines se dédouble : voir y est également synonyme de viser une cible et de l’atteindre par les armes. L’œil numérique devient « œil armé » lorsque le mouvement du regard est appelé à diriger celui de canons mitrailleurs ou de lance-missiles embarqués à bords de drones ou d’hélicoptères de combats.
Des images fantômes qui nous regardent : l’œil de la machine soumis au regard des artistes
Authors: Dietschy Nathalie
Published: May 2023

À la fin des années 1980, Paul Virilio (1988) observe la délégation croissante de l’œil humain par les machines de vision. Le régime des images automatisées est caractérisé par l’« aveuglement » des machines. Cet article propose de réfléchir aux rapports entre œil humain et vision computationnelle et les manières dont ces regards sont traités par plusieurs artistes contemporains aux pratiques et approches très différentes (Harun Farocki, Trevor Paglen, Julien Prévieux, Eva et Franco Mattes, Miguel Chevalier, Paolo Cirio). Des images opérationnelles (Farocki, 2004) dans un contexte militaire aux enregistrements de Google Street View, en passant par la reconnaissance faciale, cet article propose, par l’analyse de quelques œuvres exemplaires, de réfléchir aux visions de l’ordinateur et invite à penser l’œil machinique comme un œil qui n’est jamais « naïf » (Debray, 1994), mais qui s’inscrit au contraire toujours dans des enjeux et des contextes matériels, sociaux, politiques ou économiques, autrement dit proprement humains, et dont il s’agit de dévoiler la teneur pour que les yeux « aveugles » de la machine soient rendus visibles.
Expérience esthétique en milieu numérique

L’article interroge l’influence de l’environnement numérique sur notre expérience des œuvres d’art. Il s’agit d’identifier certains traits saillants des modifications structurelles de notre rapport aux œuvres, en mettant en dialogue le paradigme de l’expérience esthétique tel qu’il est défini par Jean-Marie Schaeffer, et le paradigme de l’attention post-numérique pensé par Katherine Hayles et Yves Citton. Cette réflexion, portant sur l’effet de l’environnement numérique sur nos comportements cognitifs, affectifs, sensoriels, ne se limite donc pas à l’étude d’œuvres d’art utilisant un medium numérique.

Common solutions to some extended system of fuzzy ordered variational inclusions and fixed point problems
Authors: Ahmad Iqbal , Sarfaraz Mohd , Irfan Syed Shakaib
Published: May 2023

The main aim of this work is to use the XOR-operation technique to find the common solutions for a new class of extended system of fuzzy ordered variational inclusions with its corresponding system of fuzzy ordered resolvent equations involving the $ \oplus $ operation and fixed point problems, which are slightly different from corresponding problems considered in several recent papers in the literature and are more advantageous. We establish that the system of fuzzy ordered variational inclusions is equivalent to a fixed point problem and a relationship between a system of fuzzy ordered variational inclusions and a system of fuzzy ordered resolvent equations is shown. We prove the existence of a common solution and discuss the convergence of the sequence of iterates generated by the algorithm for a considered problem. The iterative algorithm and results demonstrated in this article have witnessed, a significant improvement for many previously known results of this domain. Some examples are constructed in support of the main results.
Stochastic multiple attribute decision making with Pythagorean hesitant fuzzy set based on regret theory
Authors: Zhang Nian , Yuan Xue , Liu Jin , Wei Guiwu
Published: May 2023

The objective of this paper is to present an extended approach to address the stochastic multi-attribute decision-making problem. The novelty of this study is to consider the regret behavior of decision makers under a Pythagorean hesitant fuzzy environment. First, the group satisfaction degree of decision-making matrices is used to consider the different preferences of decision-makers. Second, the nonlinear programming model under different statues is provided to compute the weights of attributes. Then, based on the regret theory, a regret value matrix and a rejoice value matrix are constructed. Furthermore, the feasibility and superiority of the developed approach is proven by an illustrative example of selecting an air fighter. Eventually, a comparative analysis with other methods shows the advantages of the proposed methods.
Physical fitness in Austrian elementary school children prior to and post-COVID-19
Authors: Drenowatz Clemens , Ferrari Gerson , Greier Klaus , Chen Sitong , Hinterkörner Franz
Published: May 2023

Background

With the emergence of the COVID-19 pandemic, many countries implemented policies that included movement restrictions, social distancing and school closures in order to control the spread of the virus. Even though these actions may have been necessary to save lives, there have been some unintended consequences that could affect future public health.

Methods

The present study uses data from more than 24,500 Austrian elementary school children (51.2% male) that participated in a state-wide fitness evaluation program, which was initiated in the 2016/17 school year. In addition to body weight and height, data on cardiorespiratory endurance, muscular power, speed, agility, flexibility and object control were collected from three cohorts prior to the implementation of movement restrictions (school years: 2016/17, 2017/18, 2018/19) and one cohort in 2022, after the majority of COVID-19 policies had been lifted.

Results

Body mass index percentiles were significantly higher in children post-COVID-19 (p < 0.01). Further, cardiorespiratory endurance, agility and flexibility were significantly lower post-COVID-19 compared to the years preceding movement restrictions (p ≤ 0.01), while absolute muscular strength was higher in the year 2022 (p < 0.01).

Conclusion

Given the detrimental effects of COVID-19 policies on physical fitness in children, additional efforts are necessary that include versatile opportunities for physical activity and the promotion of physical fitness in order to modify the observed negative health trajectories and ensure future public health.
¿Tecnología o acompañamiento del parto? La relación profesional sanitario-gestante en España a lo largo del siglo XX
Authors: Ruiz-Berdún Dolores
Published: May 2023

En España, como en otros países del entorno, durante el siglo XX, la atención al parto hospitalario fue desplazando progresivamente al parto domiciliario. En el entorno clínico, la relación de los profesionales sanitarios con las gestantes sufrió grandes transformaciones, derivadas, fundamentalmente, de la pérdida de las posibilidades de elección de las parturientas durante el proceso obstétrico. Paralelamente, los protocolos y los adelantos científicos, como la monitorización cardio-tocográfica, propiciaron la tecnificación y medicalización del parto, lo que a su vez tuvo implicaciones en la relación entre gestantes y profesionales sanitarios, quienes no siempre fueron conscientes de cómo todas estas transformaciones afectaban a las mujeres durante parto.
Effect of antioxidant-enriched microcrystalline cellulose from almond residue on physicochemical and textural characteristics of mayonnaise
Authors: Ünver N. , Çelik Ş.
Published: May 2023

The purpose of this study was to investigate whether antioxidant-enriched microcrystalline cellulose from almond residue (AE-MCC-AS) affects the physicochemical and textural characteristics of mayonnaise during 56 days of storage at 25 °C. The L * value of the mayonnaise decreased by increasing the AE-MCC-AS ratio; whereas the redness and yellowness values increased. The emulsion stability and viscosity increased by increasing the AE-MCC-AS ratio from 0.2% to 0.4%; however, they decreased with an increase in the AE-MCC-AS ratio from 0.4% to 0.6%. The largest oil droplets were observed in the micrographs of the control, 0.2% AE-MCC-AS-M and 0.6% AE-MCC-AS-M; while the smallest ones were observed in the micrographs of α-tocopherol-M, BHT-M and 0.4% AE-MCC-AS-M. During the storage period, the total MUFA and PUFA showed a declining trend in all treatments with a higher decrease in the control; while total SFA showed an upward trend with a higher increase in the control. In terms of textural characteristics, a significant declining trend (P < 0.01) was observed in firmness and consistency; whereas an upward trend was observed in cohesiveness during the storage in all treatments.
Les zones d’éducation prioritaire (ZEP) rurales en France (1981-1998)
Authors: Heurdier Lydie
Published: May 2023

En 1981, la création des zones d’éducation prioritaire a concerné des territoires en prise avec des difficultés sociales et scolaires, qu’ils soient urbains ou ruraux. Il s’agissait de lutter contre l’échec scolaire grâce à un projet interdegrés et partenarial, élaboré après un diagnostic établi collectivement par les acteurs locaux. Le choix d’intégrer dans le dispositif des établissements ruraux a varié dans l’espace et le temps, selon les académies et les départements. Depuis la relance de cette politique en 1998, il reste peu de territoires ruraux classés sans pour autant que les problèmes initiaux aient été résolus. La politique conduite par les autorités déconcentrées a oscillé entre mesures classiques de soutien à la ruralité et projets privilégiant les liaisons interdegrés et les partenariats liés au classement en éducation prioritaire.

Background: Early postoperative neurocognitive disorders (ePND), include both emergence delirium, which is defined as very early onset postoperative delirium, and emergence agitation, defined as motor arousal. Although research on anesthesia emergence is limited, ePND are likely associated with unfavorable outcomes. This meta-analysis assessed the effect of ePND on clinically relevant outcomes.Methods: A systematic search of studies published between 2002 and 2022 on MEDLINE, PubMed, Google Scholar, and the Cochrane Library was performed. Studies that included adults with emergence agitation and/or delirium and reported at least one of the following outcomes: mortality, postoperative delirium, length of post-anesthesia care unit stay, or length of hospital stay were included. The internal validity, risk of bias, and certainty of the evidence were assessed.Results: A total of 16,028 patients from 21 prospective observational studies and one case-control retrospective study were included in this meta-analysis. The occurrence rate of ePND was 13% (data excluding the case-control study). The mortality rate was 2.4% in patients with ePND vs. 1.2% in the normal emergence group (risk ratio [RR]: 2.6, P = 0.01, very low quality of evidence). Postoperative delirium occurred in 29% of patients with ePND and 4.5% of patients with normal emergence (RR: 9.5, P < 0.001, I2 = 93%). Patients with ePND had a prolonged length of post-anesthesia care unit stay (P = 0.004) and length of hospital stay (P < 0.001).Conclusions: This meta-analysis suggests that ePND are associated with twice the risk of mortality and a 9-fold increased risk of postoperative delirium.

Introduction:

Optimum patient compliance is required for periodontal-health maintenance during orthodontic treatment. The study aims to evaluate knowledge, attitude and practices regarding periodontal awareness among orthodontic patients of different treatment duration that may affect the outcome of orthodontic treatment.

Materials and Methods:

A total of 180 patients undergoing orthodontic treatment were grouped under three categories based on the duration of fixed orthodontic treatment, with each group of 60 participants. (Group A - <6 months duration, Group B - 6–12 months duration and Group C - >12 months duration). A questionnaire (total of 34 questions) was provided to each to assess the periodontal-health knowledge and awareness among subjects with an orthodontic appliance.

Results:

86.5% of participants were well aware of their periodontal health. 93.9% of participants believed that it is important to follow OHI given by the clinician. 91.9% of participants affirmed that regular dental visits enhance periodontal health. 88.8% of participants believed that it is important to brush more after wearing fixed orthodontic appliances. 89.3% of patients feel needed to visit regularly for follow-up after wearing orthodontic appliances. Only 40.6% of participants were aware of the indication for bleeding gums. 34% of subjects did not know about the prevention of gum disease, and very few believed that it could be prevented by regular brushing and flossing.

Conclusion:

Results suggested that awareness and attitude regarding oral health are moderate. Hence, it is necessary to increase awareness about knowledge, attitude and practice about periodontal health and hygiene to combat the adverse consequences during orthodontic treatment.

Published: May 2023

Introduction:

Irrigation is a major part of successful root canal treatment due to the fulfilment carried out of various essential mechanical, chemical and miro-biological functions that include the healing of periapical tissues. This way, they reach areas of the root canal wall easier, which are not touched by any mechanical instrumentation. The important factor is to go for the initial and primary endodontic treatment, otherwise known as root canal treatment. The focus should be on using root canal disinfection to prevent infection. The widely used endodontic irrigant is sodium hypochlorite. It has many limitations; therefore, there has been a study going on for many years to replace to get an ideal root canal irrigant! Various studies are being conducted in an attempt to replace sodium chloride with newer root canal irrigants. There has been wide research conducted for several years to use new endodontic irrigant materials in place of sodium hypochlorite and ethylenediaminetetraacetic acid. Many solutions are available in the new age practice of endodontic practice with plenty of advantages. Hence the objective of this study is to conduct an in depth research of such available literature in lieu of usage of natural based products in endodontics.

Materials and Methods:

By making use of the Google Scholar, MEDLINE and PubMed databases, this study has been conducted. Large data covering the relevant and potential literature, along with review articles in the English language were looked upon.

Results:

The extensive research of literature resulted in the varied examples of the usage of herbal products in the field of endodontics are pulp–dentine repair, cleaning, disinfection, removal of smear layer, sealer cement for lubricating, removal of obturation material by dissolving it, etc. This signifies that there is a strong possibility for establishing the fact that herbal based products can be effectively be used in endodontics with further detailed studies being conducted.

Conclusion:

As per the research conducted, “Naturodontics” does have a good potential although there is an extensive need for elaborative in-vitro and in-vivo studies, confirming the same.

Published: May 2023

Coronavirus disease 2019 (COVID-19) is characterized by multi-organ involvement, including respiratory and cardiac events. Echocardiography is widely considered the first-choice tool for the evaluation of cardiac structures and function because of its reproducibility, feasibility, easy to use at bedside, and for good cost-effectiveness. The aim of our literature review is to define the utility of echocardiography in the prediction of prognosis and mortality in COVID-19 patients with mild to critical respiratory illness, with or without known cardiovascular disease. Moreover, we focused our attention on classical echocardiographic parameters and the use of speckle tracking to predict the evolution of respiratory involvement. Finally, we tried to explore the possible relationship between pulmonary disease and cardiac manifestations.

Published: May 2023

Background:

Human immunodeficiency virus (HIV) affects many organ systems in the body including the cardiovascular system, often manifesting as a subclinical left ventricular (LV) systolic dysfunction that may progress to heart failure.

Aim:

This study assessed the prevalence of LV systolic dysfunction in children on highly active antiretroviral therapy (HAART) with established clinical stage 1 HIV-disease.

Materials and Methods:

The study was a cross-sectional comparative study conducted in Aminu Kano Teaching Hospital from April to August 2019 on 200. It involved study participants comprising 100 WHO clinical stage 1 HIV-infected children and 100 control subjects, aged between 1 and 18 years selected using systematic sampling method. Echocardiography was carried out on the study participants who had already completed a pretested questionnaire.

Results:

Out of 100 HIV-infected children studied, 49 were males and 51 females (Male: Female ratio; 0.96:1.0). The mean age at diagnosis of HIV infection was 2.6 (±2.6 years) and the median viral load was 35 copies/ml. The mean ejection and shortening fractions in HIV-infected children were 59.0% and 31.0%, respectively, compared to 64.4% and 34.0% in control subjects, respectively, and were statistically significant (P = 0.000). The prevalence of LV systolic dysfunction was 8.0% (8 out of 100) in HIV-infected children while the control groups had zero prevalence (P = 0.002). The age at diagnosis correlated negatively with LV systolic dysfunction (r = 0.23, P = 0.02).

Conclusion:

This study found a subclinical LV systolic dysfunction in an HAART-established clinical stage 1 HIV-infected children. The age at diagnosis was negatively correlated with the LV systolic function. This study, therefore, support the inclusion of routine echocardiography into the evaluation of HIV-infected children.

Published: May 2023

Background:

The relationship between visual assessment and longitudinal strain during dobutamine stress echocardiography (DSE) remains poorly investigated. This study assessed wall motion segments visually graded as normokinetic, hypokinetic, and akinetic at baseline and the peak of DSE and compared with longitudinal strain between segments with and without induced impaired contractility and improved contractility during DSE.

Methods:

This study included 112 patients examined by DSE, consisting of 58 patients referred for diagnostic study and 54 patients referred for viability study. Regional left ventricular (LV) contractility was assessed visually and longitudinal strain was measured using echocardiography transthoracic.

Results:

At baseline, the strain of LV segments was −16.33 ± 6.26 in visually normokinetic, 13.05 ± 6.44 in visually hypokinetic, and −8.46 ± 5.69 in visually akinetic segments. During peak dose, the strain of LV segments was −15.37 ± 6.89 in visually normokinetic, −11.37 ± 5.11 in visually hypokinetic, and −7.37 ± 3.92 in visually akinetic segments. In segments with visually observed impaired contractility, the median longitudinal strain was significantly lower than in segments without impaired contractility. For segments with visually observed improved contractility, the median longitudinal strain was significantly higher than for segments without improved contractility. In diagnostic study, sensitivity of visual assessment for absolute decrease of >2% longitudinal strain was 77%, respectively. In the viability study, the sensitivity was 82% for an absolute decrease of ≥2% longitudinal strain.

Conclusions:

There is good association between strain analysis value and visually assessed wall motion contractility.
