First-principles Modeling of the Absorption spectrum of Crystal Violet in Solution - The Importance of Environmentally-driven Symmetry Breaking
Authors: Bashirova Dayana , Zuehlsdorff Tim
Published: January 2024

Theoretical spectroscopy plays a crucial role in understanding the properties of materials and molecules. One of the most promising methods for computing optical spectra of chromophores embedded in complex environments from the first principles is the cumulant approach, where both (generally anharmonic) vibrational degrees of freedom and environmental interactions are explicitly accounted for. In this work, we verify the capabilities of the cumulant approach in describing the effect of complex environmental interactions on linear absorption spectra by studying Crystal Violet (CV) in different solvents. The experimental absorption spectrum of CV strongly depends on the nature of the solvent, indicating strong coupling to the condensed-phase environment. We demonstrate that these changes in absorption lineshape are driven by an increased splitting between absorption bands of two low-lying excited states that is caused by a breaking of the D3 symmetry of the molecule, and that in polar solvents this symmetry-breaking is mainly driven by electrostatic interactions with the condensed phase environment, rather than distortion of the structure of the molecule, in contrast with conclusions reached in a number of previous studies. Our results reveal the importance explicitly including a counterion in the calculations in nonpolar solvent due to electrostatic interactions between CV and the ion. In polar solvent, these interactions are strongly reduced due to solvent screening effects, thus minimizing the symmetry breaking. Computed spectra are found to be in reasonable agreement with experiment, demonstrating the strengths of the outlined approach in modeling strong environmental interactions.

Published: January 2024

Photoelectrochemical (PEC) systems offer a promising platform towards direct solar light harvesting and chemical storage. However, most prototypes employ wide bandgap semiconductors, moisture-sensitive inorganic light absorbers, or corrosive electrolytes. Here, we introduce PEC devices based on an organic donor-acceptor bulk heterojunction (BHJ), which demonstrate long-term H2 evolution and CO2 reduction in benign aqueous media using a carbon-based encapsulant. Accordingly, PCE10:EH-IDTBR photocathodes display long-term H2 production for 300 h in a near-neutral pH solution, whereas photocathodes with a molecular CO2 reduction catalyst attain a CO:H2 selectivity of 5.41±0.53 under 0.1 sun irradiation. Their early onset potentials enable the assembly of PCE10:EH-IDTBR - BiVO4 artificial leaves, which couple unassisted syngas production with O2 evolution, sustaining a 1:1 ratio of CO to H2 over 96 h of operation.
Impact of Symmetry and Donor Set on the Electronic Energy Levels in Nine-coordinated Eu(III) and Sm(III) Crystals Structures Determined from Single Crystal Luminescence Spectra
Authors: Mortensen Sabina Svava , Nielsen Villads R. M. , Sørensen Thomas Just
Published: January 2024

Lanthanide luminescence is characterised by “forbidden” 4f-4f transitions and a complicated electronic structure. Our understanding of trivalent lanthanide(III) ions luminescence is centered on Eu3+ because absorbing and emitting transition in Eu3+ occur from a single electronic energy levels. In Sm3+ both absorpbing and emitting multiplets have a larger multiplicity. A transition from the first emitting state multiplet to the ground state multiplet will result in nine lines for a Sm3+ complex. In this study, high resolution emission and excitation spectra were used to determine the electronic energy levels for the ground state multiplet and first excited state multiplet in four Sm3+ compounds with varying donor set and site symmetry. This was achieved by the use of Boltzmann distribution population analysis and experimentally determined transition probabilities from emission and excitation spectra. Using this analysis it was possible to show the effect of changing three oxygen atoms with three nitrogen atoms in the tricapping donor set for compounds with the same Trigonal Tricapped Prism (TTP) site symmetry on the crystal field splitting in both Eu3+ and Sm3+ crystals. This work celebrates the 40 year annivesary for the first report of [Eu(ODA)3]3- luminescence by Kirby and Richardson.

Published: January 2024

β-Hydroxy esters are essential building blocks utilised by the pharmaceutical and food industries in the synthesis of functional products. The asymmetric reduction of β-keto esters using cell-free enzymes presents a viable approach to manufacture enantiomerically pure β-hydroxy esters. However, the unbearable economic costs underlying enzymes and cofactors call for innovative approaches to maximize their reusability. Herein, we develop two self-sufficient Heterogeneous Biocatalysts (ssHBs) for the enantiodivergent reduction of β-keto esters to yield enantiomerically pure β-hydroxy esters. A thermophilic (S)-3-hydroxybutyryl-CoA dehydrogenase from Thermus thermophilus HB27 (TtHBDH) and an (R)-specific ketoreductase from Lactobacillus kefir (LkKRED) are selected, kinetically characterised, and immobilised onto macroporous agarose beads. Finally, the immobilised enzymes are coated with cationic polymers to co-immobilise the required redox cofactors. The resulting ssHBs catalyse the asymmetric reduction of β-keto esters without the exogenous supply of NAD(P)H and using 2-propanol as an ancillary electron donor. Then, we construct two enantiodivergent packed bed reactors (PBRs) integrating these two ssHBs and determine their optimal operational parameters through condition screening and kinetic simulations. The ssHBs in continuous flow operation exhibit good operational stability, illustrated by a maximum Space-Time Yield (STY) of 49.5 g L-1 h-1 for the continuous production of enantiopure ethyl 3-(R)-hydroxybutyrate over 21 days. Under these conditions, LkKRED and NADPH achieve total turnover numbers of 9.3 x 105 and 2.7 x104, respectively. Upon mass metric analysis, we conclude that these ssHBs meet the efficiency and sustainability standards to be implemented in some industrial processes, advancing the concept of self-sufficient biocatalysis for process intensification.
Fluoride Retention During Low Temperature Organic Removal from Imidazolium-Containing Zeolites by Ozone Treatment
Authors: Gao Zihao Rei , Márquez Álvarez Carlos , Balestra Salvador R. G. , Yu Huajian , Villaescusa Luis A. , Camblor Miguel
Published: January 2024

For zeolites synthesized using imidazolium cations, the organic matter can be extracted at very low temperatures (100 ºC) using ozone. This is possible for zeolites with 12-ring or larger pores, but requires higher temperatures in medium pore zeolites. The first chemical events in this process occur fast, even at room temperature, and imply the loss of aromaticity likely by formation of an adduct between ozone and the imidazole ring through carbons C4 and C5. Subsequent rupture of the imidazole ring provides smaller and more flexible fragments that can desorb more readily. This process has been studied experimentally, mainly through infrared spectroscopy, and theoretically by density functional theory. Amazingly, fluoride anions occluded in the small double four-ring units (d4r) during the synthesis remain inside the cage throughout the whole process when the temperature is not too high (≤ 150 oC). However, fluoride in larger cages in MFI ends up bonded to silicon in penta or hexacoordinated units, likely out of the cages, after ozone treatment at 150 ºC. For several germanosilicate zeolites, the process allows their subsequent degermanation to yield stable high-silica zeolites. Quaternary ammonium cations, require harsher conditions that eventually also extract fluoride from zeolite cages, including the d4r unit.

Authors: John Jesteena , S M Varsha , George Robin
Published: January 2024

The terms "monochorionic" and "diamniotic" refer to multiple gestations with just one placental disk (or chorion) and two separate amniotic cavities, respectively. Each fetus in a monochorionic diamniotic twin pregnancy has its own amniotic sac in addition to the common placenta. PPROM is the rupture of membranes before the onset of labor and before 37 weeks of gestation. We present a case of a 33-week-old primigravida female with monochorionic diamniotic twin gestation, Rh negative pregnancy, and PPROM who presented to the labour room with a fully dilated cervix, an emergency lower segment caesarean section was performed with prolonged second stage labour, and twins were delivered.

Authors: Dhamotharan Jothieswari , M Prathyusha , Nelavala Audi Narayana
Published: January 2024

This study was conducted to evaluate the Factors Affecting Medication Adherence in patients suffering from Rheumatoid Arthritis. The study included 135 patients who came to the Rheumatology department and were diagnosed with Rheumatoid Arthritis. The study was conducted from May 2023 to November 2023. Male and female subjects, aged ?18 years, and diagnosed with RA were included in the study. Demographic data, disease- and treatment-related data, adverse event profile and investigation data were obtained from all the participants. Among 135 patients 26 patients were adherent to their medications and 109 patients were non-adherent to the medications. The success of the treatment of Rheumatoid arthritis depends both on patient compliance and treatment efficacy. Improving adherence to therapy could therefore dramatically improve the efficacy of drug therapy. Increased knowledge of the impact of therapeutic adherence of patients with RA and identification of possible predictors of adherence will allow to develop strategies to promote adherence. Upper lower-class patients were found to be significant with the medication adherence.

Authors: Pankaj Kumar
Published: January 2024

Communication over the wireless has significantly evolved to the level where it is capable of supporting the essential controlling mechanisms of the high-definition automated industrial process. The Fifth-Generation (5G) mobile networking air-based interface, named New Radio (5GNR), is presently capable of adopting scalable control and subband data transmission for small data packets, which has made it efficiently compatible for the critical controlling application of industrial automation processes. The minimum cycle time is used as a reliable parameter for an indication of the healthy techniques for industrial wireless telecommunication, but it has not undergone deep investigation within the framework of modern 5G technology. For addressing such types of challenges, this paper has taken into consideration 5G-based industrial automation process control through wireless networking by using a delay optimization approach associated with data-base channel control using the Ant Colony Optimization (ACO) approach for solving the proposed evaluation of a reliable minimum cycle time over 5G network communication.

Authors: Ortiz-Zableh Ana María , Sandoval-Ojeda Juan Manuel , Patiño-Covelli Natalia , Bolívar-Aguilera Isabel Cristina , Ortiz-Azuero Alfredo
Published: January 2024

Objective: The objective of this report is to present the case of metastatic melanoma to the bladder, a rare and underdiagnosed condition due to its often asymptomatic characteristic. Case presentation: The case was a 62-year-old female patient, with a history of melanoma at the level of the first toe, with surgical and pharmacological management. The reason for consultation was hematuria. Cystoscopy revealed a single solid, erythematous lesion with necrosis and easy bleeding, and transurethral resection (TUR) was indicated. The pathology found metastatic ulcerated melanoma. Second-line treatment (pembrolizumab) was started and presented progression to the upper limbs and relapse at the bladder level. The patient died a year later. Discussion: Melanoma metastases to the genitourinary tract are common, but isolated bladder metastases are rare. Treatment is usually TUR of the lesion, cystectomy, chemotherapy, and radiation therapy. TUR is curative for lesions restricted to the epithelium, although radical cystectomy is usually the therapy of choice in patients with a localized tumor. Pembrolizumab has been shown to increase survival. The prognosis depends on the size and depth of the invasion. Conclusion: Metastatic cancer to the bladder is rare and underdiagnosed, it may be present in patients with melanoma, nonspecific urinary irritative symptoms, and hematuria. It tends to have a poor prognosis, and requires surgical treatment associated with systemic management.

O presente artigo tem a intencionalidade de discutir a perspectiva da Pesquisa-Trans-Formação, modalidade de pesquisa que vem sendo desenvolvida por um grupo pertencente ao Programa de pós-graduação em Educação: Psicologia da Educação, o Grupo Atividade Docente e Subjetividade (GADS). Esta modalidade traz em sua significação histórica um chamamento para o agir revolucionário, tensionando a atuação crítica e transformadora que pode ser excitada na realidade pesquisada. Este artigo versa sobre um recorte analítico acerca dos encontros formativos realizados junto a uma média de quinze professores de escolas públicas da cidade de São Paulo, que se propuseram a discutir os desafios dos processos de ensino-aprendizagem durante a pandemia. O objetivo desta pesquisa foi a apreensão da dimensão subjetiva dos processos educacionais em tempos de pandemia e os seus desdobramentos. A intenção de desenvolver pesquisas e formações, decisivamente nesta perspectiva crítica marxista da qual tratamos aqui, pode ser percebida no movimento práxico científico desta modalidade de pesquisa - que tem como pedra angular a crítica, a necessidade de apreensão da realidade social para além de sua aparência, que considere o movimento histórico da realidade, que mantenha a coerência teórico-metodológica na concepção dialética das interrelações teoria-prática-método-técnica-síntese, tudo isso rigorosa e explicitamente assumido desde a escolha do objeto, do objetivo, dos procedimentos e formas de análise e de interpretação. Nesse caminho orientado pela dialética pesquisar-formar-transformar, tendo por base as contribuições de Karl Marx, Lev Vigotski e Paulo Freire, refletimos neste artigo sobre o potencial do desenvolvimento de formações realizadas sob a modalidade da Pesquisa-Trans-Formação, mostrando a relevância dos processos da pesquisa na criação de importantes mediações na formação de consciência crítica e desvelamento de condições de alienação.
Emotional burnout of healthcare professionals: models, risk factors and protective factors
Authors: Assonov Dmytro
Published: January 2024

Emotional burnout (also known as professional burnout, burnout syndrome) is a serious mental health problem for physicians, nurses and other healthcare professionals around the world. The positive dynamics observed between 2014 and 2017 are a cause for optimism and indicate that progress is possible and that more needs to be done to combat burnout. However, despite this progress, the incidence of burnout among physicians is still higher than in the general population. Thus, further research on emotional burnout and systematization of both risk and protective factors is needed. The purpose of this review article is systematization of burnout-related information to outline further ways of development. We analyzed the literature on the topic published over the past 5 years. Databases such as PubMed, APA PsychNet, Google Scholar, Scopus and Web of Science were used to search the literature. Emotional burnout of health workers is associated with a number of risk factors, which can be divided into work-related, social and psychological. The greatest importance in the occurrence of the syndrome hold work-related factors. In addition, a number of professional, social and psychological factors are associated with a decrease in the level of emotional burnout, and therefore have protective properties. The main group of protective factors against emotional burnout are psychological factors, such as emotional intelligence, empathy, optimism, internal control, certain character traits. Despite much research on this topic and the latest advances in psychotherapy, so far, we can only talk about reducing the prevalence of emotional burnout to the level of a decade ago. This suggests that the increase in the prevalence of emotional burnout worldwide has been slowed, but further research on prevention and new, more effective and evidence-based psychosocial methods of dealing with emotional burnout are needed to further reduce the prevalence.
Application of anxiolytics and β1-adrenoblockers in combination with cognitive-behavioral therapy to reduce anxiety disorders in young people with vegeto-vascular dystonia
Authors: Hrubliak Viacheslav
Published: January 2024

The article is devoted to the problem of the influence of autonomic dysfunction and anxiety disorders on the quality of life and performance of young people. The relevance of the study is beyond doubt, because vegetative-vascular dystonia is the most common pathology among adolescents and young adults. The author of the article emphasizes that functional autonomic (vegetative) disorders without appropriate correction eventually transform into organic nosological diseases, such as coronary heart disease and hypertension. Anxiety disorders and panic attacks often accompany vegetative disorders, especially in young people, and are actually obligate in the development of vegetative crises of the cerebral or cardiac type, which as a result leads to temporary disability and reduced quality of life. In the complex treatment of vegetative-vascular dystonia in young people with anxiety disorders, the use of cognitive-behavioral therapy in combination with pharmacotherapy – anxiolytic (buspirone) and a selective β1-adrenergic blocker (bisoprolol) was proposed. The dynamics of the general condition, clinical and physiological indicators and the level of anxiety in persons with cardiac, cephalic and arrhythmic syndromes are determined. As a result of the treatment of young people with vegetative-vascular dystonia, a positive effect of selective β1-adrenergic blockers on the general condition, clinical and cardiodynamic parameters was revealed in the form of disappearance or significant reduction of pain and heart rhythm disorders, normalization of blood pressure, regression of neurotic, especially anxiety disorders with simultaneous cognitive behavioral and anxiolytic therapy with buspirone, which can be recommended for use in young people, as well as young men and adolescents, in the process of training and acquiring professional skills, to improve the quality of life and prevent the development of behavioral disorders and organic complications in the future.

Background. Social anxiety disorder (social phobia) is one of the most common variants of anxiety pathology, which is mainly characterized by a chronic course, persistent symptoms, and a tendency to relapse. Negative social experience in the pathogenesis of social phobia may be accompanied by signs resembling avoidance symptoms, negative alterations in cognition/mood, and changes in arousal and reactivity. In addition, recent scientific studies indicate that individuals with social anxiety disorder suffer from clinically significant symptoms of PTSD in response to social trauma, which impairs quality of life and increases the risk of suicide attempts. Aim. Investigate the clinical and psychological features of people with signs of social anxiety disorder associated with traumatic experiences. Materials and methods. The study group included 179 individuals who complained of significant psychoemotional distress due to avoidance of social interaction and symptoms characteristic of social anxiety disorder with a history of more than six months. The mean age was 31.45 ± 3.84 years, 77.09% (138) were female, 76.5% (137) had higher education, and 26.81% (48) lived alone. As part of the screening of the mental state, we used The MINI: International Neuropsychiatric Interview, self-questionnaires, and scales from complex IAPT were used to study the pathopsychological symptoms, and the Q-LES-Q-SF self-questionnaire was assessed for quality of life. Objective. The study found that individuals who reported significant distress due to avoidance of social interaction were more often diagnosed with social phobia and panic disorder (with and without agoraphobia). They are more characterized by higher levels of psychopathological symptoms, psychosocial dysfunction, and lower subjective satisfaction with the quality of life than the control group. Social avoidance in people with social phobia who have experienced an immediate threat to life was primarily due to comorbid manifestations of post-traumatic symptoms and the impact of traumatic experiences. At the same time, people with social phobia who were affected by social events, defined as traumatic, showed a combination of anxiety and depressive symptoms, which led to distress associated with the avoidance of social interaction. In our opinion, cognitive and behavioral strategies characteristic of the clinical picture of social phobia affect adaptation difficulties, exacerbating distress in daily activities and reducing satisfaction with the quality of life. In addition, for those with a life-threatening experience, the traumatic experience should be considered a separate factor. In contrast, those with a social trauma experienced a modifying factor of vulnerability. The obtained results may lead to different approaches to psychocorrectional work and require further research.

Russian aggression disrupted delivery of mental healthcare services for veterans in Ukraine. These causes required to create some new solutions about artificial intelligence based (AI-based) psychological services for Ukrainian defenders. Specialists from the Centre for veterans’ mental health “Forest Glade” of Ministry of Health of Ukraine have created a Telegram-based bot (Lisova Poliana Bot) to reach the specific needs of veterans and servicemen. Such form of AI-based service achieved positive feedback from soldiers, officers and volunteers and helped to partially unload the psychological service in wartime without excluding the Ukrainian defender from it. Therefore, AI solutions have a potential to be integrated in healthcare system. Given the great potential of artificial intelligence in the provision of services during the war, further comprehensive research and cooperation at the international level can be promising. We invite international researchers to cooperate in creating and delivering AI-based consulting tools for Ukrainian defenders.

Background: Social restrictions during the COVID-19 pandemic, such as being forced to stay at home, observing social distancing in public places, or having to switch to remote work (study), increased difficulties with social interaction. Although quarantine measures mitigated the "harmful impact of the pandemic" through psychological distancing from the typical stressors of social interaction, for individuals prone to social anxiety disorder, they contributed to the consolidation of avoidance strategies, prevented the disconfirmation of dysfunctional beliefs and unproductive expectations. Psychosocial support programs focused on affordable and flexible interventions will help improve resourcefulness, prevent excessive distress in difficult life circumstances, and relapse of comorbid mental health disorders. The aim: To study changes in symptoms and levels of psychosocial dysfunction in individuals with social anxiety disorder as a result of completing an online psychological support program based on low-intensity CBT. Materials and methods: One hundred thirteen individuals with a social anxiety disorder and/or complaints that meet the diagnostic criteria for this disorder according to DSM-5 were enrolled in an online low-intensity intervention program based on the cognitive-behavioral model during the COVID-19 pandemic. In 6 months after completing the program, 84 people underwent a mental state assessment using the SCL-90-R scale. Also, assessed was the influence of experiential (emotional) avoidance on the severity of symptoms and their reduction. Results. According to the results of the pilot study, it was found that the proposed program of psychosocial support for people suffering from social anxiety disorder contributed to the reduction of psychosocial distress and the severity of mental symptoms in the six months after its completion. Low-intensity techniques based on CBT, offered in an online format, have demonstrated effectiveness and sustainability of effects with regular practice in everyday life. Since the program is focused on reducing avoidance strategies as a pathogenetic mechanism, these changes can be considered preventive factors. Conclusions: The presented results are preliminary and limited by several factors: in particular, adaptation to martial law conditions. Considering the positive feedback from participants, the flexibility of the proposed program, and the prognostically positive results reflected in the moderate experimental effect of exposure on comorbid symptoms and the level of severity of distress, we see the perspective of further research and the implementation of the program for practical use.
War in Ukraine: Psychiatry from the frontline

This text contains information about new data from the National Military Medical Clinical Center "Main Military Clinical Hospital" A retrospective analysis of of medical history data from Military Medical Clinical Center of the Northern Region (Ukraine) has showed a 7-fold increase in the number of hospitalizations during active hostilities. Anxiety, dissociative, stress-related, somatoform and other non-psychotic disorders (F40 - F48) were the most common mental health issues, accounting for 76.1% of cases of hospitalization. (Hydabrus, 2022). Phenomena of alexithymia was quite common among active servicemembers, and could be an predictor of early onset of PTSD and prevent patients from service usage due to lack of insight of mental health symptoms (Chaban et a.l, 2018, Frankova et al., 2019). The main characteristics of alexithymia are marked dysfunction of emotional awareness, social attachment and interpersonal relationships. Current assessment tools for PTSD, for example CAPS-5 or PCL-5 do not evaluate the degree of alexithymia. Untimely detected PTSD combined with alexithymia leads to the phenomenon of "rapid aging" after the war. The rapid aging is a syndrome composed of progressive asthenia (rapid aging, weight loss, mental weakness and the desire to have rest); post-traumatic rent-seeking behavior (aquired disability with benefits and privileges provided, transition to a passive life position), and a complex of "militarized psyche" characterized by desire to be understood, despite the fact that alexithymia also manifests itself in ineffective decoding of the emotions of others. All this causes an increase in cruelty, intransigence, rigidity to the moral guidelines of society, a decrease in thresholds of sensitivity to social influences, etc. Phenomenon of alexithymia is an important prognostic factor and psychotherapeutic targets in effective management of a patient with PTSD.
