Authors: Doman Marc , Para Marylou , Caudron Julia , Rozencwajg Sacha , De Montmollin Etienne 
Published: March 2024

L’admission en soins critiques du patient transplanté cardiaque est fréquente aussi bien en post opératoire immédiat qu’à distance de la transplantation. La prise en charge de ces patients relève d’une approche multidisciplinaire en raison des nombreuses problématiques hémodynamiques, cardiaques, infectieuses, immunologiques et pharmacologiques. Nous aborderons dans un premier temps le péri-opératoire de la transplantation cardiaque avec ses complications spécifiques, puis les problématiques pouvant survenir plus à distance : les infections bactériennes et opportunistes, la gestion des immunosuppresseurs, le diagnostic et le traitement du rejet aigu, la vasculopathie du greffon, l’insuffisance rénale et enfin la place de l’assistance circulatoire.

Material analysis of tool feed on scrap machines using the vibration method
Authors: Kharis Surnadi Ahmad , Subekti Subekti  
Published: March 2024

Flexibility comes from the cutting force generated when the workpiece and tool react and are moved to different areas of the scrap machine. The chisel will get damaged as a result. The material and cutting speed that are used can cause damage. Given this, further studies employing the vibration method are required to determine the ways in which material affects the speed at which scrap is chopped. PVC, iron, and aluminum 5052 were the materials used in this investigation. The cutting rotational speeds varied from 32 to 80 m/min. To measure vibration, the accelerometer is positioned along the x, y, and z axes. The measurement outputs of the accelerometer are connected to the FFT Analyzer, which performs analysis using Matlab. When comparing cutting speeds above or below 50 m/min, the research results indicate that the x-axis has the largest amplitude and the most form variants. The most widely used material is PVC, which is followed by iron and aluminum. This is because, unlike aluminum and iron, which have microstructures in the form of crystal grains, PVC is a thermoplastic polymer with a microstructure made of chain molecules. Because all of the cutting energy is used in the frictional action between the chip and the workpiece when the tool is being used, the high frequency is the result. As a result, the friction on the sliding plane is breaking up atomic or molecular bonds. Additionally, the cutting force exerts a significant amount of pressure on the tool's wearing active surface
Painting robot with three axis motion

Published: March 2024

Paint was applied directly to the painted surface while painting with a brush. There are occasionally unsatisfactory outcomes, such as paint stacking or streaks remaining. Spray guns yield better paint results, therefore a robot was developed that can regulate the spray gun's movement in order to apply paint. A painting robot that resembles an arm is one that has three axes of movement. The robot can move left-right on the x axis, up-down on the y axis, and back-front on the z axis. Its end effector is a spray cannon. An ultrasonic sensor is used to measure the distance between components and the spray gun; when the sensor measures near distances, such as between 4 and 8 cm, the test sensor distance measurements have a larger average error. When the test reading distance is increased from 10 cm to 14 cm, the average error reduces. Superior painting outcomes can be achieved with a paint distance of 10 cm, an air pressure of 80 psi, and a spray gun arm movement speed of 25 rpm. With average x-axis movement of 74.6 cm, y-axis movement of 14.8 cm, and z-axis movement of 88.2 cm, the largest volume that can be painted is 97,517.5 cm3. The rotation of the arm is used to determine the angular rotation needed to paint components. Painting the left side of the component at an angle of 10°, the back side at an angle of 100°, the right side at an angle of 190°, and only painting the front side of the component at the required angle of 90° require the rotational movement of the arm to the left.

Published: March 2024

The world's richest flora may be found in Indonesia, where a variety of plants, such as the sesame plant (Melastoma malabathricum L) or MM, may be used to treat cancer. According to earlier studies, the methanol extract of the leaves had a substantial anticancer effect on the MCF-7 cell line, with an IC50 of 7.14 µg/mL. The purpose of this study was to evaluate the cytotoxic potential of the water, ethyl acetate, and n-hexane fractions of senduduk leaf ethanol extracts. Maceration was the extraction technique, partitioning (liquid-liquid extraction) was the fractionation technique, and the MTT method was employed to assess cytotoxic activity. The n-hexane, ethyl acetate, and water fractions showed cytotoxic effects with IC50 values of 137.200 µg/mL, 17.108 µg/mL, and 610.863 µg/mL, respectively. The water and n-hexane fractions were classified as fragile, based on the results of the cytotoxicity test. The ethyl acetate fraction, on the other hand, was added to the active category for suppressing MCF-7 cells.

The limestone formations are a unit of geological rock formations that are important for the formation of unique Karst landscapes but are often threatened by development interests, one of which is in the environment around Goa Peteng, whose existence is threatened. This research aims to investigate: 1) the conditions of limestone formations around Goa Peteng, 2) identified threats to the existence of limestone formations around Goa Peteng, and 3) potential opportunities for protecting the existence of limestone formations around Goa Peteng. The methods used in this research include field observation, literature review, and assistance with map digitization. This assistance involves utilizing literature studies, both scientific articles and reports containing maps that also cover the study location. The results of the research show that the limestone formations in the Goa Peteng environment exist at of a level of karst development in the Goa Peteng environment, which is Mesokarst and parts of the surrounding area are Non-Karst apart from that there is Exokarst Potential and Endokarst though not much exists at the study location. The real threat to the existence of the karst landscape in the Goa Peteng environment is the development of mass tourism in the form of tourist accommodation such as hotels and villas, which has developed rapidly over the last 14 years, as seen from Satellite Image data. The limestone formations in the Goa Peteng environment themselves has the opportunity to be a place for education and further studies need to be carried out on the limestone formations and karst development in South Bali.
Liens entre les pratiques enseignantes perçues au collégial, le SEP à réussir ses études et le stress des étudiants
Authors: Pelletier Christine , Frenette Éric , Gaudreau Nancy 
Published: March 2024

Les étudiants inscrits aux études postsecondaires vivent de plus en plus de détresse psychologique. Cette situation, surtout documentée d’un point de vue clinique et dans le but d’organiser les services spécialisés offerts aux étudiants (Baik et al., 2019), a été observée dans les cégeps du Québec (Gosselin et Ducharme, 2017). La présente étude pose la question suivante : que peuvent faire les personnes enseignantes pour développer le sentiment d’efficacité personnelle (SEP) des étudiants et diminuer leur stress? Une meilleure connaissance des pratiques enseignantes susceptibles de développer le SEP des étudiants à réussir leurs études pourrait fournir des éléments de réponse à cette question. Ainsi, cette étude de type quantitatif et exploratoire s’intéresse aux liens unissant les pratiques enseignantes au collégial, le SEP à réussir ses études et le stress (n = 355) à partir d’une analyse acheminatoire. La discussion porte sur les principaux résultats : 1) les perceptions de pratiques enseignantes varient selon le genre, l’âge et le programme d’études, 2) le SEP-études est influencé par quatre types de pratiques : défis d’apprentissage et choix des tâches, modelage par l’enseignant et autres modèles, messages d’efficacité et relations positives, 3) le degré de stress est influencé par le SEP-études, ainsi que par 4)le genre des répondants et les messages de peur de l’enseignant, et 5)le SEP-études présenterait un effet indirect sur la relation entre d’une part les messages d’efficacité et le stress, et d’autre part les relations positives et le stress.

Published: March 2024

Objective:
To elucidate the relationship among knowledge, attitudes, and practices regarding Covid-19 and their relationship with booster vaccination status among women with infertility.

Methods:
This questionnaire-based cross-sectional study was performed online and offline among women with infertility who visited an infertility clinic in Jakarta, Indonesia. We assessed the patient’s knowledge, attitudes, and practices regarding Covid- 19 and their relationship with booster vaccination status and sociodemographic profile.

Results:
A total of 178 subjects participated in this study, and most participants (92.6%) had received booster Covid-19 vaccines. From the questionnaire, 74.2% had good knowledge, and 99.4% had good attitudes regarding Covid-19; however, only 57.9% of patients had good practices. A weak positive correlation existed between knowledge and attitudes (r=0.11, P=0.13) and a moderate negative correlation between attitudes and practices (r=-0.44, P=0.56). Participants’ knowledge about vaccines and infertility was correlated with booster vaccination status (P=0.04). Academic background (P=0.01) and attitudes (P=0.01) were also correlated with booster vaccination status. The significant determinants of hesitance of receiving Covid-19 booster vaccines were high school education or below (OR=0.08, 95% CI 0.02-0.36) and poor practices (OR=0.21, 95% CI 0.05-0.95).

Conclusions:
The majority of the participants had received the Covid-19 booster vaccine and had good knowledge and attitudes but poor practices regarding Covid-19. Most participants had poor knowledge about the relationship between infertility and the Covid- 19 vaccine. The general population should be more informed and reminded about practices to prevent Covid-19 and the relationship between vaccination and fertility to increase the number of people who receive Covid-19 booster vaccines.

Areca nut – A gift by nature but a sweet poison for oral environment: A comprehensive review
Authors: Aga Nausheen , Vanka Aruna , Shreevats Ruchira , Gupta Sonia , Mohamed Hassan Muna Eisa , Matcheswala Fatema 
Published: March 2024

Abstract

Background:
Nature provides us with a diversity of plants and fruits. These organic plants and the products they produce might have some therapeutic potential that can be applied to the treatment of specific bacterial and pathological disorders of the body. Yet, some of these ingredients may have harmful effects on tissue and health if they are abused. In Hindu culture, areca nuts (ANs) are widely used for food, Ayurvedic medicine, and social and religious purposes. Nonetheless, frequent use may cause some changes to the oral environment.

Aim:
The purpose of this review is to provide an overview of how AN addiction affects the oral environment and dental health.

Materials and methods:
Electronic research of the published English literature was performed in PubMed/Medline, Science Direct, Web of Science, Embase, Google Scholar, and Scopus databases, from 2001 to 2023 using mesh keywords such as (areca nut or betel nut) and (oral tissues or oral cavity or oral environment). A manual search of all the related journals was also performed. We also checked the reference lists of the relevant articles.

Conclusions:
Although the AN plays a positive function in dental and digestive health, excessive ingestion can have negative effects on the environment and oral tissues. The globe is now aware of using this sweetener with caution because of the increased prevalence and incidence of numerous oral illnesses induced by this habit for the last few years, especially in school-age youngsters. It has been discovered that this behavior is linked to even the precancerous diseases and lesions that lead to mouth cancer. Hence, it is essential to persuade them to stop chewing ANs to avoid further difficulties.

Effect of Flax seed oil and Ashwagandharishta on various behavioral and pharmacological models of depression in Swiss albino mice
Authors: Tanna Ila Revachand , Chandola Hari Mohan 
Published: March 2024

Abstract

Background:

Linum usitatissimum Linn., commonly known as flax seed or linseed, is known to be the richest plant source of alpha linoleic acid, an omega 3 fatty acid, whereas Ashwagandharishta, an Ayurvedic classical formulation, is the treatment remedy for Apasmara (epilepsy), Murchha (syncope), and Unmada (psychosis).

Aim:
The aim of the present study is to evaluate the antidepressant effect of flax seed oil and Ashwagandharishta on various behavioral and pharmacological models of depression.

Materials and methods:
The healthy Swiss albino mice were randomly divided into five groups: (i) Normal control i.e., water control, (ii) vehicle control - Milk control (7.4 mL/kg), (iii) flax seed oil with milk (2.6 mL/kg), (iv) Ashwagandharishta (6.5 mL/kg), and (v) flax seed oil with milk followed by Ashwagandharishta (2.6 mL/kg + 7.4 mL/kg+ 6.5 mL/kg). The antidepressant effect was evaluated using behavioral despair test, anti-reserpine test, and L-DOPA potentiation test.

Results:
Flax seed oil, when administered with milk as the vehicle was found to be an excellent antidepressant in behavioral model of depression [P < 0.001 [vs. control]; P < 0.05 [vs. milk]] as well as against reserpine-induced depression (P < 0.05). However, it failed to exert a similar effect in the L-DOPA potentiation test. Whereas Ashwagandharishta showed moderate antidepressant activity in behavior despair test (P < 0.05) as well as against reserpine-induced depression (P < 0.01) and failed to exert L-DOPA potentiating effect.

Conclusion:
Flax seed oil and Ashwagandharishta exhibit a significant antidepressant effect in various behavioral and pharmacological models of depression in Swiss albino mice.
