Published: December 2023

Spirituality is an important aspect of treatment and recovery for substance use disorders (SUDs), but ambiguities in measurement can make it difficult to incorporate as part of routine care. We evaluated the psychometric properties of an adapted short-form version of the Spirituality Scale (the Spirituality Scale–Short-Form; SS-SF) for use in SUD treatment settings. Participants were adult patients ( N = 1,388; Mage = 41.23 years, SDage = 11.55; 68% male; 86% White) who entered a large, clinically mixed inpatient SUD treatment program. Factor analysis supported the two-dimensional structure, with factors representing Self-Discovery and Transcendent Connection. Tests of measurement invariance demonstrated that the scale was invariant across age and gender subgroups. The SS-SF exhibited convergent and concurrent validity via associations with participation in spiritual activities, hopefulness, life satisfaction, 12-step participation, and depressive symptoms. Finally, scores on the SS-SF were significantly higher at discharge compared to admission, demonstrating short-term sensitivity to change. These findings support use of the SS-SF as a concise, psychometrically sound measure of spirituality in the context of substance use treatment.

Authors: Rusu Daiana Maria , Stevanović Dejan , Enea Violeta
Published: December 2023

Parental stress among parents of children with autism spectrum disorder (ASD) is well-documented in the literature. This study used the mediation model to investigate the relationship between the phenomenon of affiliate stigma and parental stress among parents of children diagnosed with ASD. This cross-sectional study involved 196 parents between 22 and 65 years of age with a child diagnosed with ASD whose age was between 2 and 22 years. The correlations between affiliate stigma, shame, and parental stress were confirmed. Therefore, affiliate stigma was positively associated with shame and parental stress. The results also indicated that the relationship between the phenomenon of affiliate stigma and parental stress is mediated by shame. A practical implication of our findings is that parents of children with ASD participating in stress-reducing interventions should be trained on how to cope with feelings of shame.

Authors: Chan Kylie Kai-yi , Yeung Nelson Chun-yiu , Mo Phoenix Kit-han , Yang Xue
Published: December 2023

Despite the high prevalence of perceived stress and mental health problems among medical professionals (MPs), their professional help-seeking is extremely low. This qualitative study explored MPs’ stressors, stress-coping, barriers and facilitators of professional help-seeking. 10 MPs (30% male, Mage = 34.8 years) were recruited by purposive-sampling for views from different roles/settings. Thematic analyses revealed five central stressors: emerging novel diseases, challenges from technology-advancement, patient-communication difficulties, lack of workplace mental health care culture, excessive workload/manpower shortage. Participants predominantly used peer support/supervision and de-stress activities for stress-coping. Five factors affecting professional help-seeking were time constraint versus flexibility, mental health stigma versus de-stigmatization, concern over confidentiality/anonymity versus sense of privacy, worry about damage on professional role versus least work disruption, doubts of service providers versus perceived efficacy. All participants indicated a preference for online mental health service delivery. Results reflected unmet needs and service gaps from MPs’ perspectives for the development of future interventions.
Love is love: Reverse isomorphism and the rise of LGBTQ+ romance publishing
Authors: Larson Christine , Carter Ashley
Published: December 2023

In the late 2010s, US romance publishing underwent an astonishing change. Previously, same-sex couples were all but nonexistent in romances released by major publishers. By 2022, every large publisher in the United States issued romances featuring same-sex couples: A few also published bisexual, trans, or polyamorous romances. This article turns to neo-institutionalism to analyze how processes of isomorphism contributed to this change. Through interviews with 10 authors and 7 editors, we show how specific mechanisms associated with isomorphism—coercion, mimesis, and normative pressures—explain this major shift. Contrary to prevailing literature, we find that structural innovations moved from publishing’s periphery to its core in a process we call reverse isomorphism. We contribute to discussions of representation in media by showing how social, organizational, and institutional processes facilitate or suppress underrepresented voices. At the same time, we caution that new structures may create new types of marginalization.
Spotlighting ‘Medical Collegiality’
Authors: Ng Isaac KS , Tan Sarah ML , Law Lawrence SC , Tan Li Feng , Teo Desmond B
Published: December 2023

‘Collegiality’ comes from the Latin term ‘Collegium’, which essentially refers to a community of individuals bounded by their collective pursuit of a common goal. The concept has historical roots in both organised religion and academia, with its use subsequently extended to various industrial and corporate settings including healthcare. Nowadays, ‘collegiality’ has become a common buzzword adopted by the medical fraternity – often deemed as having a polite and respectful demeanour, maintaining cordial work relationships and being a team player who demonstrates willingness to help others and avoid speaking ill of fellow colleagues. While it is true that workplace incivility, aggression, bullying and verbal abuse are not uncommonly reported in highly stressful healthcare settings, which are concerning phenomena that should be addressed and prevented, the concept of ‘medical collegiality’ is, in reality, a rich and multi-faceted concept that is not limited to behavioural attributes, but extends to larger cultural principles and organisational constructs. In this article, we herein define ‘medical collegiality’ as ‘a collective manifestation of respect, empathy and solidarity within the medical fraternity, driven by a common pursuit of clinical excellence in patient care, demonstrated through interpersonal/work relationships and organisational culture’, by referencing historical origins of ‘collegiality’ in organised religion and academia. We further review the concept of ‘medical collegiality’ through three core lenses of cultural, behavioural and structural collegiality. Finally, we discuss the importance of medical collegiality for physician mental health and well-being, and quality of clinical care.
Gender Minority Stress and Resilience Measure: A Meta-Analysis of the Associations with Mental Health in Transgender and Gender Diverse Individuals
Authors: Wilson Laura C. , Newins Amie R. , Kassing Francesca , Casanova Tracy
Published: December 2023

Transgender and gender diverse (TGD) individuals are more likely to experience mental health difficulties than cisgender individuals due to unique stressors related to their stigmatized gender identity and/or expression. This meta-analysis examined the associations between gender minority stressors and resilience factors, as measured by the Gender Minority Stress and Resilience Measure (GMSR; Testa et al., 2015), and two types of mental health symptoms (i.e., depression and anxiety). A comprehensive literature search and study inclusion process following PRISMA guidelines identified 69 sources, representing 47 unique samples. Mean effect sizes revealed significant positive associations between all GMSR minority stress subscales and anxiety and depression symptoms ( rs = .22 to .40) with larger correlations for proximal stressors compared to distal stressors. The GMSR resilience subscales were significantly negatively correlated with anxiety and depression symptoms ( rs = −.07 to −.16). These findings highlight the robust relationship between gender minority stressors and mental health symptoms among TGD individuals and indicate a need for addressing these stressors both by reducing exposure to external stressors and by addressing the internalization of those stressors in clinical settings. The small effects for the resilience subscales suggest a need to examine additional resilience factors that may be more pertinent to mental health among TGD individuals.
The Professionalization of Stigma: The Novel Case of Recovery Coaching
Authors: Silcox Joseph W. , Stewart Evan
Published: December 2023

Research on stigma management techniques often emphasizes reducing and challenging negative associations with stigmatization. How do people manage stigma in social groups where negative associations may be socially or professionally advantageous? We answer this question with a case study of the emerging industry of “Recovery Coaching,” where firsthand experiences with drug use and recovery are part of a credentialing system that offers entry into a professional field. Drawing on interviews with 22 participants, 15 of whom were certified recovery coaches, we demonstrate the presence of a unique stigma management technique: the professionalization of stigma. Recovery coaches explicitly leverage revealing stigmatized associations to establish and justify their membership in a professional group. We distinguish the professionalization of stigma from conventional management techniques that reduce stigma and discuss the implications of this concept for the study of destigmatization under neoliberal social and economic conditions across different subfields of sociological research.
Successes and Challenges in Implementing a Human Trafficking Screening Tool in a Local Detention Center
Authors: Hill Leslie , Hefner M. Kristen
Published: December 2023

Research solidly documents the victim-offender overlap in various crimes, including human trafficking. Given the hidden nature of this exploitative crime, increasing the identification of victims is crucial. One way to do this is through the creation and implementation of screening tools. To date, most screening tools for human trafficking victims are created by and implemented in the field of health care or with youth or young adults, particularly those who have experienced housing instability. However, the use of these tools to identify victims of human trafficking in correctional settings—where victims are often misidentified as offenders—is limited. To address this deficiency, a victim-centered, trauma-informed screening tool was implemented in a local detention center to identify human trafficking victims, with the purpose of offering them resources to facilitate their exit from trafficking situations. This article outlines the creation and implementation of the tool and discusses its successes, challenges, lessons learned, and recommendations for replication.
Distributed Discovery of News and Perceived Misinformation Exposure: A Cross-Continent Application of the Resilience to Online Disinformation Framework
Authors: Chan Michael , Kuznetsov Dmitry , Yi Jingjing , Lee Francis , Chen Hsuan-Ting
Published: December 2023

Perceived misinformation exposure (PME) among citizens is a global phenomenon and a normative concern because it can lead to reduced trust and faith in democratic institutions, actors, and processes. Using secondary data from multiple sources, this study analyzed individuals’ online news habits across forty-six countries in six continents (North America, South America, Europe, Asia, Africa, and Australia: N = 91,061) and country-level factors from the resilience to online disinformation framework that shape the relationship between distributed discovery of news and PME. Multilevel analyses showed that increased incidental news exposure and searching for news online at the individual level and news sharing on social media at the country level increased PME while aggregate media trust reduced PME. Cross-level interactions also indicated that higher levels of public service media in a country attenuated the relationship between online news search and PME, exhibiting what we call soft resilience. This study demonstrates the theoretical utility of the resilience to disinformation framework and certain country-level factors that can affect the individual-level dynamics of news consumption and PME.
When Fact-Checking Is Not WEIRD: Negotiating Consensus Outside Western, Educated, Industrialized, Rich, and Democratic Countries
Authors: Vinhas Otávio , Bastos Marco
Published: December 2023

This study unpacks the emerging framework of detection, verification, and correction of falsehoods developed by fact-checkers outside Western, Educated, Industrialized, Rich, and Democratic countries. We explore a series of semistructured interviews carried out in several languages with thirty-seven fact-checking experts from thirty-five organizations in twenty-seven countries across Africa, Asia, Latin America, and Eastern Europe. Our findings emphasize the contextual nature of the falsehoods that these professionals deal with on a daily basis, and the many strategies they employ to navigate cultural and political obstacles while strengthening social cohesion locally. We review these findings against the literature in the area and argue that the prevailing framework of fact-checking, where misinformation and disinformation are reduced to individual and behavioral problems, underplays the social and historical dimensions driving disinformation and propaganda.
Skin Tone and Inequality of Socioeconomic Outcomes in Mexico: A Comparative Analysis Using Optical Colorimeters and Color Palettes
Authors: Solís Patricio , Güémez Braulio , Campos-Vázquez Raymundo M.
Published: December 2023

We study the association between skin tone and socioeconomic outcomes in Mexico. Previous studies have relied on subjective measures of skin tone, but these may suffer from measurement error and bias from “money lightening” effects, and they do not include other physical attributes, which could lead to overestimation. We use a new data source in Mexico specifically designed to address these challenges, including an objective measurement of skin tone based on optical colorimeters. We find that the estimates of the association between skin tone and socioeconomic outcomes are consistent across data collection techniques (interviewer-rated, self-rated, machine-rated) and surveys. Around half of the association is explained by differences in socioeconomic background, a finding that emphasizes the importance of considering both historically accumulated disadvantages and current mechanisms of generating inequality. We also find that phenotypical characteristics other than skin tone (eye and hair color) are significant predictors of socioeconomic outcomes. These findings suggest that more than a strict pigmentocracy, where light skin is the only element or the definitive one, ethnoracial stratification in Mexico may be better characterized in a broader sense: as one where people with a set of racialized physical features linked to European origins have greater accumulated privilege and social advantages than those with features linked to Indigenous or Black ancestry.
One size fits all? The role of task complexity in L2 production via the audio chat
Authors: Qian Li , Shamsudin Sarimah
Published: December 2023

The pervasive use of information and computer technology in second or foreign language learning has led researchers to explore the ideal tasks for technological environments to facilitate second language (L2) learning. This study intended to contribute new knowledge to this area by examining the effects of the task complexity manipulated along the variable +-few elements in Robinson’s Cognition Hypothesis on L2 production of 42 lower intermediate Chinese EFL (English as a Foreign Language) learners who completed two interactive tasks (simple versus complex) in dyads via audio chat of the video-conferencing platform WeMeet in a laboratory setting. Participants were also instructed to measure the difficulty of the tasks by responding to a self-rating questionnaire immediately after they completed each task. Their L2 output in the two tasks were recorded, transcribed and coded in three dimensions namely, syntactic complexity, lexical complexity and accuracy. SPSS 26 was used for statistical analyses. The results revealed that increasing task complexity induced significantly more lexically complex language. However, it did not result in significant changes in terms of syntactic complexity or accuracy of learners’ L2 output via audio chat. These results contradicted the predictions of the Cognition Hypothesis, suggesting the inapplicability of Cognition Hypothesis in audio chat.
Historia stall zachodnich w kościele Wniebowzięcia Najświętszej Marii Panny w Toruniu w świetle ostatnich prac badawczych i konserwatorskich
Authors: Raczkowski Juliusz
Published: December 2023

Autor dokonuje próby wstępnego rozwarstwienia zespołu stall chórowych w kościele pofranciszkańskim WNMP w Toruniu, korzystając z metod analizy strukturalnej wspartej badaniami nieniszczącymi (NIR) i dendrochronologią. Wywód jest skoncentrowany na jednym ich fragmencie – siedziskach, przeniesionych prawdopodobnie w XVII wieku z prezbiterium do ostatniego przęsła nawy głównej, w strefę portalu zachodniego. Meble te (dawniej zapewne jeden element należący do kompletu stall w chórze) zostały tu rozbudowane o przedpiersia i przystosowane  technicznie do wymogów nowego miejsca, a także wizualnie zharmonizowane z wzniesioną w tym czasie emporą zachodnią.  W okresie bernardyńskim ich estetykę dopasowano znów do zmian w obrębie empory (zostały ozdobione – dziś już niewidocznym – ornamentem rocaille’owym). Na nowym miejscu stalle zyskały „nowe życie” i rejestrują przemiany konfesyjnie i funkcjonalne kościoła. Osobną uwagę autor poświęca dwóm wątkom ideowym: treściom ikonograficznym gotyckiego policzka z scenami z bajek Ezopa i historii lisa Reynarta, które zostały odsłonięte po niemal stu latach w 2021 roku, oraz – uczytelnionym dzięki podczerwieni – bernardyńskim sentencjom medytacyjnym na przedpiersiach, później zamalowanym. Odkrycia te były możliwe dzięki badaniom w projekcie „Inwentarz sztuki Torunia” i sondażowej konserwacji-restauracji policzka i przedpiersi północnych w 2022 roku. Prace konserwatorskie przy stallach zachodnich są kontynuowane, a niniejszy tekst jest propozycją rekonstrukcji historii tego zabytku, która być może zostanie w przyszłości uzupełniona lub odmiennie zinterpretowana.

Authors: Tuncali Yaman Tutku , Yaylalı Serdar
Published: December 2023

The post-Covid era has witnessed the adoption of various new habits in our daily lives, particularly in relation to the ubiquitous e-commerce platforms that have become essential for urban populations. The surge in e-commerce activities and the intensified volume in delivery of packages during the pandemic sparked innovative ideas. This study explores one such creative concept: parcel pick-up points. We conducted a pioneering research endeavor to determine the optimal locations for these pick-up points in Istanbul, Turkey. Our methodology employed a novel hybrid approach, combining the Spherical Fuzzy Analytic Hierarchy Process (AHP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The evaluation of criteria importance was facilitated by a literature review and experienced high-level managers in the cargo industry, who determined the criteria weights using the Spherical Fuzzy AHP method. Subsequently, the TOPSIS method was employed to identify the most ideal locations, leading to the selection of Kadikoy, Umraniye, and Atasehir. This study provides valuable insights into the selection of the optimal locations for parcel pick-up points in Istanbul, Turkey, which can inform policymakers, e-commerce companies, and logistics stakeholders. The proposed hybrid approach demonstrates the integration of modern smart technologies with fuzzy decision-making techniques, offering a robust framework for decision support in the field of e-commerce logistics. Future research can further explore the implementation and effectiveness of these pick-up points to enhance the efficiency and convenience of last-mile deliveries in urban areas.

The identification of vortices and cores is crucial for understanding airflow motion in aerodynamics. Currently, numerous methods in Computer Vision and Machine Learning exist for detecting vortices and cores. This research develops a comprehensive framework by combining classic Computer Vision and state-of-the-art Machine Learning techniques for vortex and core detection. It enhances a CNN-based method using Computer Vision algorithms for Feature Engineering and then adopts an Ensemble Learning approach for vortex core classification, through which false positives, false negatives, and computational costs are reduced. Specifically, four features, i.e., Contour Area, Aspect Ratio, Area Difference, and Moment Centre, are employed to identify vortex regions using YOLOv5s, followed by a hard voting classifier based on Random Forest, Adaptive Boosting, and Xtreme Gradient Boosting algorithms for vortex core detection. This novel approach differs from traditional Computer Vision approaches using mathematical variables and image features such as HAAR and SIFT for vortex core detection. The findings show that vortices are detected with a high degree of statistical confidence by a fine-tuned YOLOv5s model, and the integrated technique produces an accuracy score of 97.56% in detecting vortex cores conducted on a total of 133 images generated from a rotor blade NACA0012 simulation. Future work will focus on framework generalisation with a larger and more diverse dataset and intelligent threshold development for more efficient vortex and core detection.
Integration of water, sanitation, and hygiene program with biosecurity: A One Health approach to reduce the prevalence and exposure of antibiotic-resistant bacteria in the livestock community

Published: December 2023

The global spread of antibiotic resistance poses a significant threat to public health and is one of the main causes of this problem. Livestock farming plays a significant role in the horizontal and vertical transmission of treatment-resistant genes and bacteria. These processes involve contact with agricultural products and the environment, raising concerns for public health, and farming communities. The farming community is composed of a staggering 608 million farms worldwide, and their livelihood depends heavily on livestock farming. To address this issue, a multidisciplinary One Health approach focusing on integrated monitoring and intervention for humans, animals, and the environment is essential. Water, sanitation, and hygiene (WaSH) programs have the potential to significantly reduce the risk of exposure to antibiotic-resistant bacteria, particularly extended spectrum beta-lactamase (ESBL) Escherichia coli, by obstructing the transmission route between humans and animals. Additional risk reduction measures for ESBL E. coli infection in animals include vaccination and biosecurity program implementation. Water, sanitation, and hygiene and biosecurity measures must be combined to maximize the effectiveness of the One Health program. Therefore, this study aimed to describe recent advances in biosecurity and WaSH interventions in the livestock environment, analyze the effects of these interventions on human and animal health, and investigate potential future scenarios within the quantitative microbial risk assessment framework. This study used an integrative literature review through searches of four databases, a review of World Health Organization documents through websites, and an examination of relevant texts from previously obtained reference lists. Although hygiene and sanitation are often combined, there is still a lack of quantitative evaluation of the efficacy of integrating WaSH with biosecurity in livestock. In addition, the integration of the WaSH program with biosecurity has potential as a One Health intervention in the coming years.

Keywords: antibiotic-resistant bacteria, biosecurity, extended-spectrum beta-lactamase Escherichia coli, One Health, scenario, water, sanitation, and hygiene.
Effects of Drying Techniques and Different Solvents on Phytochemical Composition and Antioxidant Activity of Carica papaya Seed Extracts: Implications for Industrial Use and Medicinal Benefits
Authors: Olatunya Ayomadewa Mercy
Published: December 2023

Plant has always been of immense health benefits to humanity because, plant contains different parts that have been found to have various medicinal and industrial values. Therefore, plants play a crucial role in obtaining their most effective extracts for medical and  industrial applications. The primary components of these preparations involve the extraction and drying methods. Carica papaya is a  plant that is known to have different parts with numerous and unexplored medicinal and industrial benefits. Thus, this study  investigated the effects of drying techniques and different extracting solvents on the phytochemical composition and antioxidant  activity of Carica papaya seeds extract using standard analytical procedures. The results showed that drying technique has significant  effect (p < 0.05) on the phytochemical composition of the C. papaya seeds with air-drying at room temperature having the highest  amount of total phenolic compounds, flavonoids, saponin content and antioxidant activity when compared to other techniques.  Hexane extracted the highest amount of total phenolic compounds (121.08 mg/GAE/100 g). Diethyl ether extracted the highest  amount of total flavonoid and saponin content while polar solvents (aqueous and ethanol) extracts have the highest amount of  antioxidant activity. This study showed that air drying at room temperature is a good method of preservation of the phytochemicals  present in medicinal plants and that stereochemistry and structural diversity of compounds determine the efficiency of their extraction  in any solvent. Furthermore, the highlighted phytochemicals and antioxidant activity of C. papaya seed extracts could be of  immense benefits in various industries and for medicinal purposes.
Anticancer and Antioxidant Activities of Biologically Active Newly Synthesized α-Amino Acid-Dithiocarbamate Complexes of Some Bivalent Metals
Authors: Kaviyarasi P. , Manivannan S.
Published: December 2023

The present study focuses on the synthesis and characterization of L-proline dithiocarbamate and its L-prodtc metal(II) (M = Ni2+, Cu2+ and Se2+) complexes. The ligand was synthesized in the presence of an alkali through the reaction of one mole of carbon  disulphide and L-proline in ethanol under ice cold condition. The solubility of this ligand in the media is attributed to its high  hygroscopic character and therefore, its metal(II) complexes were synthesized using a freshly prepared ligand. The characterization of  the metal(II) complexes were carried out by molar conductance, magnetic susceptibility, elemental analysis, TGA/DTA, mass, IR,  Raman, UV-Visible, 1H and 13C NMR spectroscopic studies. The biological activity of all the metal(II) complexes has been examined  using an inhibition method for bacteria and pathogenic fungus, which will assess their possible antibacterial, antioxidant, anticancer  activities and anti-inflammatory. It has been observed that Se(L-Prodtc)2 exhibits anticancer activity against breast cancer cells (MCF7)  and also observed that antioxidant activity of Se(L-Prodtc)2 is more as compared to standard BHT, whereas Cu(L-Prodtc)2 complex  shows appreciable anti-inflammatory activity.

Published: December 2023

In this work, co precipitation method was adopted to synthesis Cu (0.01M, 0.02M, and 0.03M) doped CaSnO3 nanoparticles and the structural, optical, morphological and electrochemical characterization were studied using XRD, FTIR, UV–Visible, Photoluminescence, SEM and Cyclic voltammetry with Electrochemical impedance analysis. It is noticed from XRD patterns that the peaks shift towards higher angles attributed to the substitution of Cu2+ ions for Ca2+ ions, and confirms the orthorhombic structure of Cu2+ doped CaSnO3. The average crystallite size is found between 40 – 49 nm for Cu doping. FTIR analysis boosts the confirmation of Cu doping in to the CaSnO3 nanoparticles by the presence of vibrational peaks at 698 cm-1, 622 cm-1, and 581 cm-1 due to Cu-O stretching and the peak 483 cm-1 due to Sn-O stretching vibration. The calculated band gap values are 4.7 eV, 4.8 eV, and 4.9 eV for Cu doping. The PL emission study showed light emission towards the visible region. SEM analysis proved well-formed cubed particles about < 2µm. Specific capacitance values are highest for 0.02 M Cu doped CaSnO3 at about 1694F/g, compared to 572 F/g, 922 F/g, and 1626 F/g for pure, 0.01 M, and 0.03 M Cu doped CaSnO3 particles, respectively, at a scan rate of 10 mV/s.  Overall, these findings indicate that 0.02 M and 0.03 M Cu doped CaSnO3 are promising candidates for energy storage applications.

Rare-earth orthoferrites are a group of compounds which exhibit improved magnetic, optical, and electrical characteristics throughout a wide range of temperatures. In present work, dysprosium based orthoferrite compound containing double phase of DyFeO3 perovskite/ Dy3Fe5O12 garnet was synthesized via co-precipitation technique. A mixed phase of orthoferrite, DyFeO3 perovskite and  Dy3Fe5O12 garnet has been obtained. The X-ray diffraction (XRD) was carried out to explore the structural arrangements of atoms in  the prepared material and clearly demonstrated the presence of both cubic phase of Dy3Fe5O12 (bcc) and orthorhombic phase of  DyFeO3 in the powder sample. The nanoparticles surface morphological behaviour is explored with field emission scanning electron  microscope (FE-SEM), which shows nearly spherical shape particles with little agglomeration. Using the UV-visible absorbance, band  gap of the prepared sample was evaluated as 2.06 eV from Tauc plot. The magnetization behaviour was observed using a vibrating  sample magnetometer (VSM), which revealed the Langevin component (ferromagnetic) at low field and as linear component  (antiferromagnetic) at high field. The electric polarization (P-E loop) studies also revealed the typical induced ferroelectric behaviour.
Interaction Mechanism of Hesperidin and L-Tryptophan: A Experimental and Molecular Docking Studies
Authors: Kanimozhi A. , Bakkialakshmi S.
Published: December 2023

The binding of L-tryptophan (L-Trp) and hesperidin (HES) was investigated by UV, fluorescence, synchronous fluorescence, time-resolved fluorescence, Fourier transform infrared (FTIR) spectroscopies, FRET, antibacterial activity, anticancer activity and molecular docking study. The flavonoid glycoside known as hesperidin has been shown to have therapeutic properties for a variety of disorders, including cancer diseases. Its low solubility and bioavailability cause it to be little absorbed, which means that a delivery mechanism is necessary in order for it to reach its therapeutic goal. Fluorescence data revealed that the fluorescence quenching mechanisms of L Trp by hesperidin are all static quenching procedures. Synchronous fluorescence spectroscopy shows the interaction between hesperidin  and L-Trp changes the hydrophobicity of the microenvironment of tryptophan (Trp) residues. The anticancer activity effect of  hesperidin and L-Trp on human cervical cancer cell lines was assessed using MTT and crystal violet assays.

Few 3-methyl-1-2-[(4-methyl-2-oxo-2H-chromen-7-yl)oxy]acetyl-4,5-dihydro-1H-pyrazol-5-one derivatives were synthesized and their structures were characterized by FTIR, 1H NMR and mass spectrometry. To assess the potential antibacterial action of a conventional medicine, a biological screening was done on Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa. Furthermore, these medicines underwent in silico ADME evaluation. Although all compounds successfully underwent the ADME  evaluation, only a limited number of compounds passed the projected toxicity test.

Expanding urban impervious surface area (ISA) mapping is crucial to sustainable development, urban planning, and environmental studies. Multispectral ISA mapping is challenging because of the mixed-pixel problems with bare soil. This study presents a novel approach using spectral and
temporal information to develop a Soil-Suppressed Impervious Surface Area Index (SISAI) using the Landsat Operational Land Imager (OLI) data set, which reduces the soil but enhances the ISA signature. This study mapped the top 12 populated megacities using SISAI and achieved an over-all accuracy
of 0.87 with an F1-score of 0.85. It also achieved a higher Spatial Dissimilarity Index between the ISA and bare soil. However, it is limited by bare gray soil and shadows of clouds and hills. SISAI encourages urban dynamics and inter-urban compari- son studies owing to its automatic and unsupervised
methodology.
