Exploring the Mixed Methods Research Design: Types, Purposes, Strengths, Challenges, and Criticisms
Authors: Sharma Dr. Lok Raj , Bidari Sandesh , Bidari Dinesh , Neupane Sushil , Sapkota Rambabu
Published: January 2023

A mixed methods research design, which is a complex approach, combines both quantitative and qualitative data in a single study or succession of studies. This design can be particularly functional for exploring complex research questions that cannot be fully answered by using a single research design. Moreover, a mixed methods design is necessary to examine the relationships between different variables because examining the relationships between diverse variables is not viable just through a single research design. This design is required to complement and cater to the increasingly multifarious requirements of contemporary researchers. This article, which explores and discusses types, purposes, strengths, challenges and criticisms of the mixed methods research design as its objectives, stems from an analysis of some notable works in the field. It is grounded on the secondary qualitative data accumulated in the forms of words from journal articles and books related to the research designs. It assists the novices in the field of research in particular and other researchers in general by providing them with an overview of mixed methods design along with its types, such as convergent parallel, explanatory sequential, exploratory sequential, embedded, transformative and multi-phage designs.

Authors: Srishti Sneha , Jain Siddhi , Gowda Rahul
Published: January 2023

In modern communication devices, microstrip patch antennas are preferred to conventional antennas due to their size. In this review, a survey of commonly used techniques and designs for microstrip antennas is conducted. These techniques and designs were used by the authors to design an effective, low-profile, small, compatible, and affordable microstrip antenna. They were mostly used to design reconfigurable, multiband, and wideband antennas. After that, a initiator patch design with dimensions is provided on which technique will be used to analyze various antenna parameters. In recent years, research into microstrip patch antennas has made significant progress. Microstrip patch horns outperform conventional microstrip patches in a number of ways, including their low cost, ease of integration with integrated microwave circuits (MICs), low volume, small size, high performance, and low weight.

An Attempt to Understand the Negotiation of Teachers’ Identities in the Context of School Reform
Authors: Neira Del Ben Paul
Published: January 2023

Political discourses that state that the quality of an educational system relies on the quality of its teachers are frequent nowadays. This approach remarks the importance of teacher’s identity. However, how many times is this issue actually taken into consideration by the educational reform processes? This question turns relevant when we realize that many of the reforms seek to penetrate the classroom, and the teachers’ own practices. The following essay is an exploration of the elements that interact to shape the teacher’s identity in the context of constant change and school reform. How do educational policies and their discourses shape these new teachers’ identities? How do these identities interact with reforms? Do these reforms match the identities of teachers or not? The importance of addressing these issues is greater when we consider that they may have an important impact—whether positive or negative—on the educational change processes.

Published: January 2023

The decrease in the functional capacity of the heart to pump blood accompanied by symptoms of dyspnea causes heart failure patients to have physical limitations. This condition causes the patient to be unable to carry out self-care optimally, thus requiring the help of others, especially family. The study aimed was to identify the relationship between family support and behavior self-care of heart failure patients. The research design used a cross-sectional with many samples as many as 104 respondents. The research variable is family support, and self-care behavior measured using a questionnaire was declared valid and reliable. Data analysis used the Spearman rank test. The results study 53,8% of respondents moderate family support, and 47,1% of respondents have fewer self-care behavior skills. The Spearman Rank test results obtained p=0,000, with a correlation coefficient value of 0,709. The study concluded a relationship between family support and the self-care behavior of patients with heart failure, the relationship positively and strong. Better family support provides better self-care behavior will be. Nurses have a role to motivate families to be actively involved during the patient's self-care process while in the hospital or at home. Self-care for patients that can be carried out by the family in the form of caring for the family with the patient's condition, accepting the family with the patient's condition, providing assistance and seeking information about the patient's illness.

GENOME-WIDE IDENTIFICATION OF NICOTIANA TABACUM MIRNAS AND THEIR ROLE IN HUMAN HEALTH – A COMPUTATIONAL GENOMICS ASSESSMENT
Authors: Bhavsar Mansi , Mangukia Naman , Manvar Toral , Mankad Archana
Published: January 2023

Tobacco kills their half of the consumers still, grown as the most lucrative crop worldwide for different uses like chewing, smoking, and snuffing. On the other side, it was known as a chief medicinal plant by Native Americans, ancient European, Amazonian and Indian. In the middle 20th century tobacco was declared a negative and hazardous plant because of its nicotine component. Nicotiana tabacum (N. tabacum) is well studied in plant biotechnology and studied as a model plant. Likewise. N. tabacum miRNAs were also identified a decade ago however a genome-wide computational approach to identify miRNAs remained to be explored. These XenomiRs and their cross-species talk were also revealed for the first time in the current study. The top ten hub nodes (CCNE1, DDX5, NEUROD1, SOS1, CUL2, OPHN1, SOX9, KCNA1, FBXW2, and NOC3L) were retrieved from the experiment which gives evidence of tobacco miRNAs and their involvement in diseases like carcinoma and neurodevelopmental disorders.

Investigating the Narrow-line Region Dynamics in Nearby Active Galaxies
Authors: Meena Beena , Crenshaw D. Michael , Schmitt Henrique R. , Revalski Mitchell , Chapman Zo , Fischer Travis C. , Kraemer Steven B. , Robinson Justin H. , Falcone Julia , Polack Garrett E.
Published: January 2023

We present dynamical models of the narrow-line region (NLR) outflows in the nearby Seyfert galaxies Mrk 3, Mrk 78, NGC 1068, and NGC 4151 using observations from the Hubble Space Telescope and Apache Point Observatory. We employ long-slit spectroscopy to map the spatially resolved outflow and rotational velocities of the ionized gas. We also perform surface brightness decompositions of host galaxy images to constrain the enclosed stellar mass distributions as functions of distance from the supermassive black holes (SMBHs). Assuming that the NLR gas is accelerated by active galactic nuclei (AGN) radiation pressure, and subsequently decelerated by the host galaxy and SMBH gravitational potentials, we derive outflow velocity profiles where the gas is launched in situ at multiple distances from the SMBH. We find a strong correlation between the turnover (from acceleration to deceleration) radii from our models, with the turnovers seen in the observed velocities and spatially resolved mass outflow rates for the AGN with bolometric luminosities > 1044 erg s−1. This consistency indicates that radiation pressure is the dominant driving mechanism behind the NLR outflows in these moderate-luminosity AGNs, with a force multiplier ∼500 yielding the best agreement between the modeled and observed turnover radii. However, in Meena et al. we found that this trend may not hold at lower luminosities, where our modeled turnover distance for NGC 4051 is much smaller than in the observed kinematics. This result may indicate that either additional force(s) are responsible for accelerating the NLR outflows in low-luminosity AGNs, or higher spatial resolution observations are required to quantify their turnover radii.
Asteroseismology: Looking for Axions in the Red Supergiant Star Alpha Ori
Authors: Severino Clara , Lopes Ilídio
Published: January 2023

In this work, for the first time, we use seismic data as well as surface abundances to model the supergiant α-Ori, with the goal of setting an upper bound on the axion–photon coupling constant g

a
γ
. We find that, in general, stellar models with g

a
γ
∈ [0.002; 2.0] × 10−10 GeV−1 agree with the observational data, but beyond that upper limit, we do not find stellar models that are compatible with the observational constraints and the current literature. From g

a
γ
= 3.5 × 10−10 GeV−1 on, the algorithm did not find any fitting models. Even so, all the axionic models considered present distinct internal profiles from the reference case, without axions. Moreover, as the axion energy losses become more significant, the behavior of the stellar models becomes more diversified, even with very similar input parameters. Nonetheless, the consecutive increments of g

a
γ
still show systematic tendencies, resulting from the axion energy losses. Moreover, we establish three important conclusions: (1) the increased luminosity and higher neutrino production are measurable effects, possibly associated with axion energy losses; (2) stellar models with axion energy loss show a quite distinct internal structure; and (3) the importance of future asteroseismic missions in observing low-degree nonradial modes in massive stars is emphasized—as internal gravity waves probe the near-core regions, where axion effects are most intense. Thus, more seismic data will allow us to constrain g

γ
better and to prove or dismiss the existence of axion energy loss inside massive stars.
Simulation of Solar Wind Turbulence near Corotating Interaction Regions: Superposed Epoch Analysis of Simulations and Observations
Authors: Ghanbari Keyvan , Florinski Vladimir
Published: January 2023

The effect of the turbulence that is associated with solar wind corotating interaction regions (CIRs) on transport of galactic cosmic rays remains an outstanding problem in space science. Observations show that the intensities of the plasma and magnetic fluctuations are enhanced within a CIR. The velocity shear layer between the slow and fast wind embedded in a CIR is thought to be responsible for this enhancement in turbulent energy. We perform physics-based magnetohydrodynamic simulations of the plasma background and turbulent fluctuations in the solar wind dominated by CIRs for radial distances between 0.3 and 5 au. A simple but effective approach is used to incorporate the inner boundary conditions for the solar wind and magnetic field for the periods 2007–2008 and 2017–2018. Legendre coefficients at the source surface obtained from the Wilcox Solar Observatory library are utilized for dynamic reconstructions of the current sheet and the fast and slow streams at the inner boundary. The dynamic inner boundary enables our simulations to generate CIRs that are reasonably comparable with observations near Earth. While the magnetic field structure is reasonably well reproduced, the enhancements in the turbulent energy at the stream interfaces are smaller than observed. A superposed epoch analysis is performed over several CIRs from the simulation and compared to the superposed epoch analysis of the observed CIRs. The results for the turbulent energy and correlation length are used to estimate the diffusion tensor of galactic cosmic rays. The derived diffusion coefficients could be used for more realistic modeling of cosmic rays in a dynamically evolving inner heliosphere.
Multiple Populations in Low-mass Globular Clusters: Eridanus

Published: January 2023

Multiple populations (MPs), characterized by variations in light elemental abundances, have been found in stellar clusters in the Milky Way, Magellanic Clouds, as well as several other dwarf galaxies. Based on a large number of observations, mass has been suggested to be a key parameter affecting the presence and appearance of MPs in stellar clusters. To further investigate the existence of MPs in low-mass clusters and explore the mass threshold for the formation of MPs, we carried out a project studying the composition of the stellar population in several low-mass Galactic globular clusters. Here we present our study on the cluster Eridanus. With blue-UV low-resolution spectra obtained with the OSIRIS/Multi-object spectrograph on the Gran Telescopio Canarias, we computed the spectral indices of CH and CN for a sample of giant stars and derived their carbon and nitrogen abundances using model spectra. A significant dispersion in the initial surface abundance of nitrogen was found in the sample, indicating the existence of MPs in Eridanus. Inspecting the age–initial mass distribution of in situ clusters with MPs, we find a slight trend that initial mass increases with increasing age, and the lowest initial masses of

log

initial

∼ 4.98 and 5.26 are found at the young and old end, respectively, which might provide a rough reference for the mass threshold for clusters to form MPs. However, more observations of clusters with low initial masses are still necessary before any firm conclusion can be drawn.
The Equilibrium of Coronal Loops Near Separatrices
Authors: Mason Emily I , Antiochos Spiro K , Bradshaw Stephen
Published: January 2023

We present numerical models from the field-aligned HYDrodynamics and RADiation code (HYDRAD) of a highly asymmetric closed coronal loop with near-singular expansion factor. This loop was chosen to simulate a coronal magnetic flux tube that passes close to a null point, as in the last set of closed loops under the fan surface of a coronal jet or a pseudostreamer. The loop has a very large cross section localized near the coronal null. The coronal heating was assumed to be uniform and steady. A siphon flow establishes itself within 4 hr of simulation time, flowing from the smaller-area footpoint to the larger-area footpoint, with high initial speeds dropping rapidly as the plasma approaches the null region. Observationally, this would translate to strong upflows on the order of 10 km s−1 from the footpoint rooted in the localized minority polarity, and weak downflows from the fan-surface footpoint on the order of a few kilometers per second, along with near-stationary plasma near the null region. We present the model results for two heating rates. In addition, we analyzed analogous Hinode EUV Imaging Spectrometer observations of null-point topologies, which show associated Doppler shifts in the plasma that correlate well with the simulation results in both direction and magnitude of the bulk velocity. We discuss the implications of our results for determining observationally the topology of the coronal magnetic field.

BACKGROUND: Uterine rupture following to placenta accreta spectrum disorder such as placenta percreta in second trimester pregnancy is a very rare obstetrical condition. This condition occurs primarily in the third trimester and leads to both fetal and maternal life-threatening complications.
CASE PRESENTATION: We report a 28-year-old woman in 24−25 weeks of gestation with scars from previous cesarean delivery came to emergency department due to acute abdomen following to intraperitoneal hemorrhage. From diagnostic modalities, it was found uterine rupture from the varicose veins of placenta percreta without tears in the uterus. Total hysterectomy was performed with good recovery and histopathology result showed placenta percreta.
CONCLUSION: In spite of being a rare case in second trimester of pregnancy, spontaneous rupture of uterus due to placenta percreta should be considered in the case of a patient with placenta percreta who presents with severe abdominal pain and acute intraperitoneal hemorrhage, even in the second trimester of gestation.
Quelle recomposition des services financiers dans l'UE27 après le Brexit ?
Authors: Beau Denis
Published: January 2023

Le Brexit a non seulement constitué un bouleversement politique majeur, mais est également à l'origine de transformations profondes pour les services financiers, compte tenu tant de l'importance de ces services dans le bon fonctionnement des économies européennes et britanniques que de leurs liens. Par ailleurs, pour l'Union européenne, le Brexit constitue assurément une opportunité sans précédent d'asseoir son autonomie en matière de financement, de renforcer sa robustesse en développant un système financier polycentrique appuyé sur des infrastructures de marché européennes et de s'inscrire comme leader en matière d'innovation. Cela n'implique pas cependant de relâcher les liens et le dialogue avec le Royaume-Uni : le maintien d'une forte coordination avec les autorités britanniques, particulièrement sur les champs de la réglementation afférents à des risques systémiques ou globaux, demeure éminemment souhaitable pour éviter d'alimenter un risque de fragmentation réglementaire qui serait dommageable.

Les liens entre les marchés financiers de l'UE et du Royaume-Uni ont-ils résisté au Brexit ?
Authors: Mitra Srobona , Pradhan Mahmood
Published: January 2023

Six ans après le référendum du Royaume-Uni, la question du Brexit n'a pas encore été résolue. Alors que l'attention se concentre principalement sur le désaccord sur les règles du commerce via l'Irlande du Nord, la résilience des flux financiers transfrontaliers entre l'Union européenne (UE) et le Royaume-Uni ne suggère aucune fracture significative dans les liens qui lient de longue date les marchés financiers de l'UE et du Royaume-Uni. Les deux parties ont été pragmatiques, permettant une transition plus douce, en se prémunissant contre les risques bien connus pour la stabilité financière d'une séparation brutale. L'initiative de l'Union des marchés des capitaux, bien que bien avancée, est loin d'offrir aux entités de l'UE un marché commun des capitaux intra-UE, ainsi que la liquidité du marché et les avantages des réseaux offerts actuellement par Londres. La réalisation de cette Union des marchés des capitaux égalisera les coûts de financement pour les entreprises et les ménages, mais requerra l'élimination des barrières aux flux transfrontaliers de capitaux financiers et bancaires dans l'UE. La préservation des liens entre le Royaume-Uni et l'UE profitera donc aux deux parties, créant un pont en direction de la longue transition vers des marchés de capitaux plus intégrés au sein de l'UE.

Ethics and Technique in Welfare Economics: How Welfarism Evolves in the Making
Authors: Baujard Antoinette
Published: January 2023

Dans le cadre d’étude welfariste, des affirmations telles que « cet état social est meilleur que tel autre état social » ou « cette politique devrait être promulguée » reposent sur l’hypothèse que le bien-être social ne dépend que du bien-être des individus et de rien d’autre. Une analyse normative du welfarisme vise à fournir une description transparente des jugements de valeur impliqués dans ces évaluations et ces recommandations, ce qui revient à s’interroger en particulier sur la notion du bien-être qui a été retenue. Cette enquête normative peut prendre deux formes et cet article défend l’idée qu’il convient de les distinguer : l’analyse éthique du welfarisme concerne le recours à une théorie éthique donnée du bien-être ; et l’analyse technique du welfarisme concerne la mesure de l’utilité individuelle qui est utilisée en pratique pour mesurer ce bien-être social. L’article passe en revue successivement quatre points de vue types portant sur l’articulation de ces deux versions du welfarisme : le point de vue standard, de l’approximation, de la preuve et de la tension. En étudiant l’interprétation normative des affirmations welfaristes, il explore les différences qui émergent entre les approches éthique et technique. JEL Codes: B4, D6, I31.
El Occidente islámico a la luz de las fuentes de la primera época abasí (ss. VIII-X): un mundo invisible
Authors: Montel Aurélien
Published: January 2023

Dentro de la riquísima literatura producida en el círculo del poder abasí entre los siglos VIII y X, el Occidente islámico (es decir, al-Andalus, el Magreb y las islas del Mediterráneo occidental) ocupa un lugar insignificante, a pesar de las pretensiones universalistas que tenían sus autores. Este silencio afecta a todos los géneros literarios, con excepción de la geografía, que experimentó un gran desarrollo en ese periodo. ¿Cómo puede explicarse esta circunstancia? Contextualizar estos textos permite considerar dos argumentos. El primero es la ausencia de datos históricos sobre Occidente a disposición de los autores de Oriente, lo que nos lleva a poner en cuestión la cronología de la formación de comunidades de sabios en el Occidente islámico, así como la circulación del saber en el mundo islámico. También se puede considerar que este silencio resulta de un desinterés deliberado respecto a Occidente, directamente vinculado con cuestiones políticas y geopolíticas. Desde una perspectiva imperial, invisibilizar el Occidente islámico -tierra de rebeldía desde mediados del siglo VIII- contribuye a diseñar un mundo ideal, cuya estructura muestra de manera implícita la centralidad de Bagdad.
Conceptualization and Models of Mulsim Counseling in Ghana
Authors: Osei-Tutu Annabella , Affram Adjeiwa Akosua
Published: January 2023

Ghana is a secular state in which Islam is the second largest religion. Counselors who follow principles in Islam and Muslim culture, comprising imams and followers, serve as de facto mental health providers, but their counseling practices have received limited research attention. This study examined the conceptualizations and counseling practices of 19 Muslim counselors aged 32–72 (M=57.83; SD=12.95) who follow principles in Islam and Muslim culture in southern Ghana. Qualitative data was obtained using one-on-one verbal interviews. Data was inductively and thematically analyzed. Results were organized around five main areas: (1) counseling inventory, (2) conceptualizations of counseling, (3) counseling models, (4) process considerations, and (5) personal prescriptions. Participants conceptualized counseling primarily as advising. They provided services in nine different languages and utilized advising and mediatorial models of counseling. The counselors attended to religious considerations and socio-gender norms in their counseling. The study fills important gaps in Muslim mental health research. Implications for professional psychology training and practice, as well as mental health research and advocacy, have been discussed.

A technique for applying a protective and hardening coating on steel 18G2S by electrodeposition from ionic melts has been developed. Melt in the triple eutectic point of salts NaF - 30%, NaCl - 16.6% and AlF3 - 53.4% is used as an electrolyte. During electrolysis, a graphite crucible was used as an anode, samples of reinforcing steel (18G2S) cleaned of corrosion and other contaminants were used as a cathode. The temperature of the ionic melt during electrolysis was 1120 ± 5K. In the process of electrolysis, the value of the electric current and voltage were controlled, the change in the mass of the deposited aluminium over a given time was measured. The current output during the deposition of aluminium was kept in the range of 89 ... 96 %. During electrolysis, aluminium diffuses into the surface layers of steel and with iron form solid solutions, intermetallic compounds and eutectics. At the same time, crystals of the FeAl3 compound (59.18% Al) appear in the structure. A further aluminium content decrease in the depth of the surface layer entails the appearance of chemical compounds of the following compositions: Fe2Al7, Fe2Al5, FeAl2 , FeAl. The elasticity limit and ultimate tensile strength of aluminium-coated samples compared to uncoated samples increased by 7.9% and 7.8% respectively. Electrochemical oxidation of samples with aluminium coating of reinforcing steel in sulfuric acid electrolyte was carried out. The oxidation rates for aluminium are set within (7.1... 8.3) 10-6 g / (s mm2) and iron (7.6 10.4) 10-6 g / (s mm2). Experimental assessment of samples oxidation rate under conditions of sulfuric acid electrolyte was carried out at an electric current value of 11 to 18 A.

Published: January 2023

This paper mainly studied the coefficient of friction (COF), wear performance and frictional vibration performance of polyphenyl ester modified polytetrafluoroethylene under dry friction and water lubrication friction conditions. Polyphenyl ester modified polytetrafluoroethylene composites were prepared by blending 20% polyphenyl ester with polytetrafluoroethylene, and the COF, wear performance and frictional vibration properties of such composites were tested. The results showed that: (1) Under dry friction conditions, as the specific pressure between the friction pairs increased, the volume of wear and the thickness of the wear increased, the COF decreased at first and then increased, the frictional vibration increased and stabilized after the pressure of 0.5 MPa. (2) Under water-lubricated friction conditions, as the specific pressure between the friction pairs increased, the COF increased, and the frictional vibration increased and stabilized after the pressure of 0.5 MPa; (3) The wear resistance of polyphenyl ester modified polytetrafluoroethylene composite under water-lubricated friction was better than that under dry friction, the COF was less than that under dry friction, and the total level of frictional vibration was slightly lower than that under dry friction. Therefore, in order to reduce frictional vibration and improve service life, the working pressure should be reduced, and the lubrication performance between the friction surfaces should be improved. Under water-lubricated friction, the maximum working pressure of the polyphenyl ester modified polytetrafluoroethylene composite system is recommended not to exceed 0.8 MPa.

The air cap nozzle grooves were modifying in the HVOF system by adding 2 and 4 vertical grooves to analyze the effect on the quality of the Cr3C2+20NiCr ceramic coating, then compared with the original (smooth) nozzle. With constant parameters of the HVOF process, such as spraying distance, time, and pressure of the gas fuel, this experiment will determine the quality of the coating, namely the thickness, hardness, and porosity observed through the ceramic coating cross-section. The results of porosity analysis using SEM and image analysis show that a nozzle with 4-grooves has a porosity of 2.42%. In contrast, the nozzle with 2-grooves has a porosity of 2.85%, and the original (smooth) nozzle has a porosity of 4.42%. The low porosity of the nozzle with 4-grooves increases the bond strength due to the lowest degree of particle porosity.

Published: January 2023

Bismuth ferrite nanoparticles were successfully synthesized by the co-precipitation method and modified by polyethylene glycol (PEG) 4000. X-ray diffraction patterns showed a sillenite structure of bismuth ferrite (Bi25FeO40) with a crystallite size of 35.0 nm and the new phase appeared after surface modification. The new phase was Bi2Fe4O9. Crystallite size increased after surface modification of nanoparticles with PEG. The highest increase of crystallite size after surface modification with PEG was 40.1 nm. Transmission electron microscopy images showed that samples before and after surface modification were polycrystalline and still agglomerated. Spectra of Fourier transform infrared showed the presence of C-O stretching at 1080 cm-1 and C-H bending vibration at 1342 cm-1 in the bismuth ferrite/PEG sample, which did not appear in bismuth ferrite sample. The magnetic measurement indicated the weak ferromagnetic properties of the samples. Saturation magnetization did not appear after a maximum external magnetic field (15 kOe) was applied. The maximum magnetization of nanoparticles was 0.5 emu/g and tended to decrease to 0.2 emu/g after surface modification with PEG. Optical properties analysis showed a shift in the maximum absorption peak of bismuth ferrite nanoparticles towards a lower wavelength (blue shift) after surface modification of the nanoparticles. The specific absorption rate (SAR) value of nanoparticles increased by increasing an alternating magnetic field (AMF) strength. The SAR values of bismuth ferrite nanoparticles were 48.8, 61.4, and 84.4 mW/g and decreased to 32.0, 45.2, and 83.3 mW/g after surface modification at the AMF strength of 150, 200, and 250 Oe, respectively.

Introduction: Curcuma zedoaria Roscoe (C. zedoaria) is used in traditional medicine for various diseases, including inflammation. This study aimed to evaluate the in vitro anti-inflammatory activity of the aqueous extract of C. zedoaria rhizome and its fractions and develop an anti-inflammatory cream incorporating its aqueous extract.
Methods: The crude aqueous extract of C. zedoaria rhizome was prepared by the decoction method. A portion of it was freeze-dried and the other part was subjected to sequential fractionation using hexane, dichloromethane and ethyl acetate. All the fractions were dried using a rotary vacuum evaporator. The dry powders of the above extracts were assessed for their in vitro anti-inflammatory activity using heat-induced egg albumin denaturation assay and compared with the reference drug, diclofenac sodium. A cream was formulated by incorporating the most effective fraction; the aqueous extract and its anti-inflammatory activity was compared against a commercially available diclofenac sodium cream.
Results: The aqueous extract of C. zedoaria rhizome and its hexane, dichloromethane, ethyl acetate fractions and the remaining aqueous extract showed anti-inflammatory activity against heat-induced protein denaturation with the IC50 values; 94.45 µg/mL, 3822 µg/mL, 373.2 µg/mL, 337.7 µg/mL and 565.4 µg/mL respectively. The IC50 value obtained for diclofenac sodium powder was 915.7µg/mL. The IC50 value obtained for the formulated cream (containing 3% w/w aqueous extract of C. zedoaria rhizome) was 1894 µg/mL. The observed IC50 value of the commercially available diclofenac sodium 1% w/w cream was 1227 µg/mL.
Conclusion: The cream formulated with the aqueous extract of C. zedoaria rhizome possesses in vitro anti-inflammatory efficacy. Further studies are required to improve its drug-releasing capacity.

Published: January 2023

Background & objectives:

There is a possibility that vaccinated people may experience lesser psychological distress due to the sense of safety felt by them against getting the COVID-19 infection as compared to those who are not vaccinated. However, there is a paucity of research examining the mental health status of this important sub-group of population. Thus, the present study was aimed to examine the pattern of psychological distress and its correlates among people receiving COVID-19 vaccine.

Methods:

This cross-sectional study assessed individuals receiving COVID-19 vaccine at a tertiary care hospital. Psychological distress and COVID-19-related anxiety were assessed using the Depression Anxiety Stress Scale (DASS-21) and the COVID-19 Anxiety Scale-7, respectively.

Results:

The study comprised 728 individuals with a mean age of 44.8 yr. Moderate levels of depression, anxiety and stress were reported by about 50, six and 15 per cent of the participants, respectively, as assessed on DASS-21. Generalized linear model and quantile regression analyses revealed COVID-19-related anxiety, and being a healthcare worker or front-line worker as significant correlates of psychological distress.

Interpretation & conclusions:

About half of the study participants receiving COVID-19 vaccine reported moderate to severe symptoms of depression. Strategies focusing on alleviation of COVID-19-related fear and anxiety might be effective in improving the symptoms of psychological distress.
