Published: May 2024

:

Natural plant sources are essential in the development of several anticancer drugs,
such as vincristine, vinblastine, vinorelbine, docetaxel, paclitaxel, camptothecin, etoposide, and
teniposide. However, various chemotherapies fail due to adverse reactions, drug resistance, and
target specificity. Researchers are now focusing on developing drugs that use natural compounds
to overcome these issues. These drugs can affect multiple targets, have reduced adverse
effects, and are effective against several cancer types. Developing a new drug is a highly complex,
expensive, and time-consuming process. Traditional drug discovery methods take up to 15
years for a new medicine to enter the market and cost more than one billion USD. However,
recent Computer Aided Drug Discovery (CADD) advancements have changed this situation.
This paper aims to comprehensively describe the different CADD approaches in identifying anticancer
drugs from natural products. Data from various sources, including Science Direct, Elsevier,
NCBI, and Web of Science, are used in this review. In-silico techniques and optimization
algorithms can provide versatile solutions in drug discovery ventures. The structure-based drug
design technique is widely used to understand chemical constituents' molecular-level interactions
and identify hit leads. This review will discuss the concept of CADD, in-silico tools, virtual
screening in drug discovery, and the concept of natural products as anticancer therapies. Representative
examples of molecules identified will also be provided.
In vitro Antioxidant Activity of 5-caffeoylquinic Acid and Ester Analogues
Authors: Dizdar Muamer , Vidic Danijela , Zeljković Sanja Ćavar , Maksimović Milka
Published: May 2024

Background:

Chlorogenic acid, an ester of caffeic acid with quinic acid, also known as 5-
O-caffeoylquinic acid (5-CQA), is a ubiquitous plant constituent that is an important intermediate in
lignin biosynthesis. In some cases, it occurs at surprisingly high levels in the leaves and fruits of
certain higher plants, such as coffee beans. Due to its catechol moiety and an extended side chain
conjugation, it easily forms a resonance-stabilised phenoxy radical, accounting for its powerful antioxidant potential.

Objective:

The objective of this work was to determine if the esterification and methylation of 5-
CQA would enhance its antioxidant activity.

Methods:

Two 5-CQA derivatives were prepared for this study. Chlorogenic acid was esterified with
methanol over Amberlite IR120-H to obtain methyl chlorogenate, while methyl 3',4´-dimethyl
chlorogenate was prepared from 5-CQA by treatment with diazomethane. Spectroscopic methods
confirmed the structure of these derivatives. Their antioxidant properties were tested to establish a
relationship between structure and antioxidant activity.

Results:

Antioxidant activity results were generated for 5-CQA and its ester analogues using eight
different methods. Depending on the method applied, results were expressed as IC50/MCE50 values or
as equivalents of the applied standard (ascorbic acid and Trolox).

Conclusion:

In most of these tests, 5-CQA showed the highest antioxidant activity compared to its
derivatives. Nevertheless, due to their hydrophobic characteristics, their ester analogues remain
promising antioxidant candidates in emulsifying systems.
Lung Cancer Prediction and Classification Using Decision Tree and VGG16 Convolutional Neural Networks
Authors: Krishna S. Udit , Lakshman A.N Barath , Archana T. , Raja K. , Ayyadurai M.
Published: May 2024

Introduction

A malignant abnormal growth that starts in the tissues of the lungs is called Lung Cancer. It ranks among the most common and lethal cancers globally. Lung Cancer is particularly dangerous because of its aggressive nature and how quickly it can extend to other areas of the body. We propose a two-step verification architecture to check the presence of Lung Cancer. The model proposed by this paper first assesses the patient based on a few questions about the patient's symptoms and medical background. Then, the algorithm determines whether the patient has a low, medium, or high risk of developing lung cancer by diagnosing the response using the “Decision Tree” classification at an accuracy of 99.67%. If the patient has a medium or high risk, we further validate the finding by examining the patient's CT scan image using the “VGG16” CNN model at an accuracy of 92.53%.

Background

One of the key areas of research on Lung Cancer prediction is to identify patients based on symptoms and medical history. Its subjective nature makes it challenging to apply in real-world scenarios. Another research area in this field involves forecasting the presence of cancer cells using CT scan imagery, providing high accuracy. However, it requires physician intervention and is not appropriate for early-stage prediction.

Objective

This research aims to forecast the severity of Lung Cancer by analyzing the patient with a few questions regarding the symptoms and past medical conditions. If the patient has a medium or a high risk, we further examine their CT scan, validate the result and also predict the type of Lung Cancer.

Methodology

This paper uses the “Decision Tree” algorithm and the Customised “VGG16” model of CNN for the implementation. The “Decision Tree” algorithm is used to analyze the answers given by the patient to distinguish the severity of Lung Cancer. We further use Convolution Neural Networks with a Customised “VGG16” model to examine the patient's CT scan image, validate the result and categorize the type of Lung Cancer.

Results

The “Decision Tree” approach for forecasting the severity of lung cancer yields an accuracy of 99.67%. The accuracy of the customized “VGG16” CNN model to indicate the type of Lung Cancer suffered by the patient is 92.53%

Conclusion

This research indicates that our technique provides greater accuracy than the prior approaches for this problem and has extensive use in the prognosis of Lung Cancer.

Authors: Alrafee Shaimaa A. , Abdelgawad Asmaa , Ali Menna-Allah Salem , Tamimi Sara
Published: May 2024

Objectives

This research assessed the efficacy of self-assembling peptide P11-4 (Curodont protect) in promoting biomimetic remineralization of dentin, thereby stabilizing the hybrid layer and enhancing the long-lasting of the resin-dentin bond.

Methods

Five premolar teeth were longitudinally sectioned to assess dentin microhardness before and after demineralization, as well as after the application of P11-4 (Curodont protect). For the microtensile test, ten premolar teeth were sectioned perpendicular to their long axes. The teeth were assigned to different groups. Following acid etching and rinsing, samples in control group I received no pretreatment, while the prepared dentin surface of group II was treated with 0.1 mL of P11-4 before the placement of the adhesive restoration. All specimens were stored in distilled water at 37 ± 2 °C for 24 hours and then underwent thermocycling. The microtensile test was measured, and the type of bond failure was evaluated. The obtained information, expressed in megapascals, was analyzed using a one-way analysis of variance (ANOVA), followed by Tukey’s multiple post hoc test.

Results

There was a statistically significant difference in hardness values after demineralization, followed by a significant increase in hardness after the application of P11-4 (Curodont protect) (p < 0.001, effect size = 0.985). No statistically significant difference was found in the microtensile bond strength between the two groups (p = 0.384, effect size = 0.582). Adhesive-type failure was more commonly observed.

Conclusion

The use of self-assembling peptide P11-4 (Curodont protect) on dentin resulted in higher microhardness than the control group without adversely affecting resin cement bond strength.

Authors: Ohniev VA , Peresypkina TV , Nesterenko VH , Martynenko NM , Pomohaibo KH
Published: May 2024

Introduction

This paper deals with the investigation of controlled risk factors associated with body weight disorders of young people with overweight and obesity. Authors are convinced that the formation of a conscious attitude to health in youth and early diagnosis of any abnormalities through the dynamic monitoring of adolescents and young people with excess body weight could help in the solution to this problem.

Methods

Statistical and sociological methods were used during the investigation. 80 students from a medical university participated in this research. In the survey, Google Forms online application were used. The authors followed all the principles of bioethics and medical deontology in conformity with the requirements of the Helsinki Declaration. The questionnaire contained points about the diet, food habits and preferences, socio-economic status of the respondent’s family, the level of their physical activity, knowledge about a healthy lifestyle, and relationships in the group.

Results

The primary processing of the obtained data was carried out using the methods of descriptive and analytical statistics with the provision of results in the form of relative indicators (Р, %) with an error (m, p). The specificity of the eating behavior of youth was connected with the absence of a food regime, the multiplicity of meals, and the low level of eating culture (lack of a permanent place to eat or eating in front of a computer or TV). Moreover, such habits, like eating before going to bed, eating under stress, or frequently visiting fast food restaurants, were typical for this group of population. A large number of young people were found to be prone to use advertised products.

Conclusion

Young people’s awareness of healthy nutrition has been found to be insufficient, and the level of physical activity in the studied group as unsatisfactory. Significant features of physical activity associated with maladaptive eating behavior have been observed to be a lack of physical activity on weekdays, absence of morning gymnastics, failure to comply with the norms of rational nutrition in the family, or low level of information about healthy nutrition.

Published: May 2024

The Internet of Things (IoT) is causing a sea change in the educational
system. IoTs are revolutionizing the classroom by making lessons more interactive and
interesting for both teachers and students. An understanding of why IoT is becoming a
vital component of daily instruction and learning is gained in this chapter, along with a
discussion of the challenges and relevance of the technology in question. According to
the study's findings, students can work together in real-time thanks to IoT devices.
Smart whiteboards, for instance, enable collaborative brainstorming, note-taking, and
writing amongst a group of people. Moreover, VR programs can imitate real-world
circumstances, providing pupils with a more comprehensive education. Teachers can
tailor their lessons to each student's individual needs with the aid of IoT devices.
Teachers can make a greater impact on student's academic performance and
engagement if they take into account how their students learn best. There are various
ways in which humankind will profit from IoT development, but these gains will not be
free. Some of the biggest drawbacks of the Internet of Things are security concerns,
technological dependency, and employment insecurity. Governments throughout the
world are investing time and energy to find solutions to these challenges and unlock the
full potential of the IoTs. The capacity to employ Internet of Things technologies to
create an interesting, dynamic learning environment is crucial for the future of
education. Incorporating Internet of Things (IoT) devices into the classroom allows
teachers to provide a more individualized, collaborative learning environment that

Assessing the Feasibility and Preliminary Effects of a Web-Based Self-Management Program for Chronic Noncancer Pain: Mixed Methods Study
Authors: Marier-Deschenes Pascale , Pinard Anne Marie , Jalbert Laura , LeBlanc Annie
Published: May 2024

Background

In Canada, adults with chronic noncancer pain face a persistent insufficiency of publicly funded resources, with the gold standard multidisciplinary pain treatment facilities unable to meet the high clinical demand. Web-based self-management programs cost-effectively increase access to pain management and can improve several aspects of physical and emotional functioning. Aiming to meet the demand for accessible, fully automated resources for individuals with chronic noncancer pain, we developed a French web- and evidence-based self-management program, Agir pour moi (APM). This program includes pain education and strategies to reduce stress, practice mindfulness, apply pacing, engage in physical activity, identify and manage thinking traps, sleep better, adapt diet, and sustain behavior change.

Objective

This study aims to assess the APM self-management program’s feasibility, acceptability, and preliminary effects in adults awaiting specialized services from a center of expertise in chronic pain management.

Methods

We conducted a mixed methods study with an explanatory sequential design, including a web-based 1-arm trial and qualitative semistructured interviews. We present the results from both phases through integrative tables called joint displays.

Results

Response rates were 70% (44/63) at postintervention and 56% (35/63) at 3-month follow-up among the 63 consenting participants who provided self-assessed information at baseline. In total, 46% (29/63) of the participants completed the program. We interviewed 24% (15/63) of the participants. The interview’s first theme revolved around the overall acceptance, user-friendliness, and engaging nature of the program. The second theme emphasized the differentiation between microlevel and macrolevel engagements. The third theme delved into the diverse effects observed, potentially influenced by the macrolevel engagements. Participants highlighted the features that impacted their self-efficacy and the adoption of self-management strategies. We observed indications of improvement in self-efficacy, pain intensity, pain interference, depression, and catastrophizing. Interviewees described these and various other effects as potentially influenced by macrolevel engagement through behavioral change.

Conclusions

These ﬁndings provided preliminary evidence that the APM self-management program and research methods are feasible. However, some participants expressed the need for at least phone reminders and minimal support from a professional available to answer questions over the first few weeks of the program to engage. Recruitment strategies of a future randomized controlled trial should focus on attracting a broader representation of individuals with chronic pain in terms of gender and ethnicity.

Published: May 2024

Background

The lack of regular physical activity (PA) in individuals with spinal cord injury (SCI) in the United States is an ongoing health crisis. Regular PA and exercise-based interventions have been linked with improved outcomes and healthier lifestyles among those with SCI. Providing people with an accurate estimate of their everyday PA level can promote PA. Furthermore, PA tracking can be combined with mobile health technology such as smartphones and smartwatches to provide a just-in-time adaptive intervention (JITAI) for individuals with SCI as they go about everyday life. A JITAI can prompt an individual to set a PA goal or provide feedback about their PA levels.

Objective

The primary aim of this study is to investigate whether minutes of moderate-intensity PA among individuals with SCI can be increased by integrating a JITAI with a web-based PA intervention (WI) program. The WI program is a 14-week web-based PA program widely recommended for individuals with disabilities. A secondary aim is to investigate the benefit of a JITAI on proximal PA, defined as minutes of moderate-intensity PA within 120 minutes of a PA feedback prompt.

Methods

Individuals with SCI (N=196) will be randomized to a WI arm or a WI+JITAI arm. Within the WI+JITAI arm, a microrandomized trial will be used to randomize participants several times a day to different tailored feedback and PA recommendations. Participants will take part in the 24-week study from their home environment in the community. The study has three phases: (1) baseline, (2) WI program with or without JITAI, and (3) PA sustainability. Participants will provide survey-based information at the initial meeting and at the end of weeks 2, 8, 16, and 24. Participants will be asked to wear a smartwatch every day for ≥12 hours for the duration of the study.

Results

Recruitment and enrollment began in May 2023. Data analysis is expected to be completed within 6 months of finishing participant data collection.

Conclusions

The JITAI has the potential to achieve long-term PA performance by delivering tailored, just-in-time feedback based on the person’s actual PA behavior rather than a generic PA recommendation. New insights from this study may guide intervention designers to develop engaging PA interventions for individuals with disability.

En el análisis de fenómenos sociales como el presente caso de estudio, no siempre es fácil hacerlo a profundidad y, por lo tanto, aportar propuestas que contribuyan al mismo partiendo solo de bases teóricas. Recurrir a la disciplina de la estadística matemática es cada vez más necesario para comprender mejor los fenómenos sociales. La apropiación del patrimonio arquitectónico, se ha dicho, es necesaria para reforzar la identidad colectiva; pero, para saber cómo se logra o cuáles elementos o acciones sociales favorecen ese vínculo, se realizó un modelo matemático con base en los resultados de una encuesta, cuyos reactivos se relacionaron con la identificación de los elementos culturales de Pachuca, entre ellos y como variable respuesta, parte de su legado arquitectónico industrial minero. El objetivo fue detectar el vínculo social existente entre habitantes y patrimonio, y, al mismo tiempo, identificar las variables que más inciden en ello.
Espacios y sentido en la política del arte dramático
Authors: Torija Aguilar Jaime
Published: May 2024

Este trabajo trata de sustentar que el arte, en particular el arte dramático, guarda una especificidad con la política a través de sus propios procesos, los cuales se relacionan directamente con acontecimientos subjetivos, creativos, individuales y sociales. Este posicionamiento, conquistado en la posmodernidad, coloca al arte en general en una condición generadora de cambios en los procesos psicosociales. Planteamos que, entre la politicidad del arte, se identifica la necesidad de mantener de forma continua el sentido de vida de los individuos, quienes han optado por dedicar sus actividades al arte escénico, así como la precisión de reafirmarse permanentemente como artistas. Para lograrlo, se exterioriza el reclamo —tanto a instituciones de educación superior como a los sectores empresariales— por mayores espacios escénicos y oportunidades laborales para su estabilidad económica. Esta lucha, por parte de los egresados de las universidades públicas, solo se puede lograr a través de la formación de grupos, condición necesaria para hacerse visibles y alcanzar sus objetivos.

Authors: A. Al-Samarai Riyadh , Obaid Abdulsalam Y. , Al-Douri Y.
Published: May 2024

Experimental study of the effects of surface roughness parameters and their relationship to the coefficient of friction (COF) on AlSi10Mg alloy. The information demonstrates that the average surface roughness (Ra) does not directly correlate with COF when sliding is presented. This work is focused on the relationship and interaction between the roughness parameters (Ra), maximum profile height (Rt), average profile slope, and COF. To alter the surface roughness effect, the samples of the alloy are chemically treated with an alkaline 0, 5, 10, 15, 25, and 50 minutes and tested under different circumstances. Using a T-05 block-on-ring tribometer, the COF is calculated, and surface roughness measurements are collected utilizing an optical system for measuring three-dimensional surfaces. The program MATLAB is used to analyze the obtained data. Contrarily, the results demonstrate that there is a substantial positive association with COF under sliding conditions, while Ra and Rt can change without affecting CO significantly.

Authors: Saltos Orrala Miguel Ángel , De Gaetano Andrés Marcelo , Acheriteguy Federico , Gómez Villavicencio Roxana
Published: May 2024

El artículo tiene como finalidad indagar y analizar el alcance y desarrollo del control constitucional en Ecuador, vigente desde la Constitución del año 2008, en el entendimiento de que ha sido la propia Corte Constitucional quien a través de su jurisprudencia ha redimensionado los caracteres y reglas de ejercicio del sistema de control de constitucionalidad, frente a un marco reglamentario impreciso que ofrece interpretaciones divergentes. Como parte de esta indagación se demostrará que el presupuesto de estabilidad, carácter constitutivo del modelo kelseniano, se encuentra en crisis. Ello, al constatarse que los Tribunales Constitucionales pertenecientes a los sistemas derivados del modelo de control de constitucionalidad concentrado, en ciertas hipótesis, modifican jurisprudencialmente las reglas del sistema de control, actuando de manera similar a las cortes supremas del modelo de la judicial review.

An Assessment of the Siltation and Sediment Generation in Yusmerg Dam Located in Jammu and Kashmir
Authors: Pandit Dr. Bashir Ahmad
Published: May 2024

Abstract: Although siltation is a natural process, human activity can speed it up and cause serious issues for reservoirs, lowering their usable volume for irrigation. One illustration of this issue was the Yusmerg dam's mirror water area shrinking by 48.3% over the course of 20 years. Thus, the purpose of this study was to assess the siltation and sediment production of the dam using a methodology that may be used for small earth dams used for agriculture. The amount of silt deposited in the reservoir was tracked for this purpose every month of the year. With a retention sediment percentage ranging from 53.9 to 94.5% and a high specific sediment output, the Yusmerg dam will fully silt in a maximum of 57 years. Restoring permanent preservation areas and clearing 17,500 m3 of silt from the dam's riverbed should be done as little as possible.
