In this report, we present a novel prodrug strategy that can significantly improve the efficiency and selectivity of combined therapy for bladder cancer. Our approach involved the synthesis of a conjugate based on a chlorin-e6 photosensitizer and a derivative of the tyrosine kinase inhibitor cabozantinib, linked by a β-glucuronidase-responsive linker. Upon activation by β-glucuronidase, which is overproduced in various tumors and localized in lysosomes, this conjugate released both therapeutic modules within targeted cells. This activation was accompanied by the recovery of its fluorescence and the generation of reactive oxygen species. Investigation of photodynamic and dark toxicity in vitro revealed that the novel conjugate had an excellent safety profile and was able to inhibit tumor cells proliferation at submicromolar concentrations. Additionally, combined therapy effects were also observed in 3D models of tumor growth, demonstrating synergistic suppression through the activation of both photodynamic and targeted therapy.
A Paradigm Shift in Catalysis: Electro- and Photomediated Nickel-Catalyzed Cross-Coupling Reactions
Authors: Palkowitz Maximilian , Emmanuel Megan , Oderinde Martins
Published: August 2023

Transition-metal cata-lyzed cross-coupling reactions are fundamental reactions in organic chemistry, facilitating strategic bond formations for accessing natural products, organic mate-rials, agrochemicals, and pharmaceuticals. Redox chemistry enables access to elusive cross-coupling mechanisms through single-electron processes as an alternative to classical two-electron strategies, which are predominated by palladium catalysis. The hallmark of this redox platform is the systematic modulation of transition-metal oxidation states by a photoredox catalyst or at a heterogeneous electrode sur-face. Electrocatalysis and photocatalysis enhance transition metal catalysis’ capacity for bond formation through electron- or energy-transfer processes. Cross-coupling conditions promoted by electrocatalysis and photocatalysis are mild and bond formation proceeds with exceptionally high chemoselectivity and wide functional group tolerance. The interfacing of abundant first-row transition-metal catalysis with electrocatalysis and photocatalysis has brought about a paradigm shift in cross-coupling technology. In particular, the merger of Ni catalysis with electro- and photochemistry ushered in a new era for carbon-carbon and carbon-heteroatom cross-couplings. We have developed enabling photo- and electrochemical methods throughout our research experience in industry (BMS, AstraZeneca), academia (Professor Baran, Scripps Research), and cross-disciplinary collaborative environments. In this Account, we will outline recent progress from our past and present labs in photo- and electrochemically mediated Ni-catalyzed cross-couplings. By highlighting these cross-coupling methodologies, we will also compare mechanistic features of both electro– and photochemical strategies for forging C(sp2)–C(sp3), C(sp3)–C(sp3), C–O, C–N, and C–S bonds. In each case study where we did not specifically develop both approaches, we will highlight related work from others for education. Through these side-by-side comparisons, we hope to demystify the subtle differences between the two complementary tools to enact redox control over transition metal catalysis. Finally, building off the collective experience of ourselves and the rest of the community, we propose a user guide to photo- and electrochemically-driven cross-coupling reactions to aid the practitioner in rapidly applying such tools in their synthetic designs.
Quantum chemical simulation of transient absorption spectroscopy in the CP29 light-harvesting complex
Authors: Saraceno Piermarco , Sláma Vladislav , Cupellini Lorenzo
Published: August 2023

Transient absorption spectroscopy is among the most valuable methods for investigating the dynamics of excitons in light-harvesting complexes (LHCs). Even in the simplest LHCs, a physical model is needed to interpret transient spectra, as the number of excitation energy transfer (EET) processes occurring at the same time is too large to be disentangled from measurements alone. Physical EET models are commonly built by fittings of the microscopic exciton Hamiltonians and exciton-vibrational parameters, an approach that can lead to biases. Here we present a first-principles strategy to simulate EET and transient absorption spectra in LHCs, combining molecular dynamics and accurate multiscale quantum chemical calculations to obtain an independent estimate of the excitonic structure of the complex. The microscopic parameters thus obtained are then used in EET simulations to obtain the population dynamics and the related spectroscopic signature. We apply this approach to the CP29 minor antenna complex of plants, for which we follow the EET dynamics and transient spectra after excitation in the chlorophyll b region. Our calculations reproduce all the main features observed in the transient absorption spectra and provide independent insight on the excited-state dynamics of CP29. The approach presented here lays the groundwork for the unbiased interpretation of transient spectra in multichromophoric systems.

Published: August 2023

Machine learning has the potential to provide tremendous value to the chemical and material sciences by providing models that promise to save time, energy, and starting material. Model training requires large amounts of clean high-quality data, and the methodology for transforming raw data to machine learning-ready data should be robust, adaptable, and accessible. However, data is often cleaned differently for different projects using proprietary code, making it difficult to compare approaches and creating additional effort for other researchers who want to work with literature-mined data. Herein, we present ORDerly, an open-source Python package with a novel benchmark for reaction data and a highly customizable pipeline for cleaning chemical reaction data stored in accordance with the Open Reaction Database (ORD) schema. ORDerly contains standard cleaning operations, such as frequency filtering and canonicalization checks, in addition to chemically-informed assignment of reaction roles using atom mapping, bespoke name resolution, and reproducible open-source benchmark generation. We use ORDerly to generate a machine learning-ready benchmark dataset for the prediction of reaction conditions, and through extensive analysis, we find the aforementioned cleaning steps to be essential to provide a high quality dataset for machine learning. In particular, we show that datasets missing key cleaning steps can lead to silently overinflated performance metrics. We then demonstrate that ORDerly can be used in an end-to-end pipeline that goes from raw data to a reaction condition prediction model in less than a day. With this customizable open-source solution for cleaning and preparing chemical reaction data, ORDerly is poised to push forward the boundaries of artificial intelligence applications in chemistry by providing a novel benchmark for chemical reaction conditions, and a data pipeline for researchers in the chemical sciences to leverage large reaction datasets.
Rational Design of Organic Molecules with Inverted Gaps between First Excited Singlet and Triplet
Authors: Pollice Robert , Ding Benjamin , Aspuru-Guzik Alán
Published: August 2023

One implication of Hund’s first rule for molecules is that the first excited triplet is for the large majority of molecules more stable than the first excited singlet. Only a handful of structural motifs are known to violate it. Recently, the potential of such molecules for emissive materials has been appreciated as their inverted singlet-triplet gaps enable favorable triplet exciton harvesting and low triplet exciton population to be utilized in both efficient and long-lived organic light-emitting diodes. Herein, we report bottom-up design of small organic molecules with inverted singlet-triplet gaps, i.e., INVEST molecules, via the Ring-Bonds-Substitutions (RiBS) ruleset which we introduce in this work. It relies on a few simple rules based on orbital interactions in alternant hydrocarbons to both minimize the exchange integral between highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) and maximize dynamic spin polarization. Using RiBS, we find many new molecules violating Hund’s first rule in their first excited states thereby greatly expanding the chemical space of potential inverted singlet-triplet gap (INVEST) emitters.

Authors: Shenoy Varsha , . Pallavi
Published: August 2023

Caecum is the initial blind part of large intestine normally located in the right iliac fossa. It receives terminal part of ileum on its posteromedial wall. Vermiform appendix is attached to caecum below the attachment of ileum. Variations in the position of caecum have been reported which can be attributed to its development. However variations in the appendix are very rare and most often reported as a finding during surgery. This article reports a cadaveric finding where terminal ileum was opening on to the anterior aspect of caecum. The vermiform appendix was U-shaped and it was fixed to pelvic brim at the bend. This anatomical variation may be of interest to the surgeons operating in the region. A rare finding of appendix which is U shaped not reported so far.

It is well recognized that young individuals with neurological impairments such as epilepsy receive less suitable assistance than young people with other chronic diseases. The period between the ages of 13 and 19 surrounding the transition to adult services is particularly crucial for promoting young peoples continued control and self-care. Epilepsy-specific biological psychosocial and biological variables can both hinder and facilitate the sharing of information and the development of self-care behaviors. The goals of the present review were to explain how young people with epilepsy aged 13 to 19 years and their parents experienced sharing information in healthcare settings to identify characteristics that affect both good and negative healthcare communication and identify what is known to be beneficial in doing so. Seizures which are frequent bursts of electrical activity in the brain are brought on by epilepsy. By the time they are adolescents almost two-thirds of all children with epilepsy outgrow their seizures. Epilepsy however maybe a lifelong condition for certain people. To better comprehend their childs condition and treatment parents should work together with their medical professionals.

PROBLEM ASPECTS OF IDENTIFICATION THE FACTORS OF SHADOWING OF ENVIRONMENTAL TAXATION IN UKRAINE
Authors: Kobushko Iana , Myroshnychenko Iuliia , Tenytska Iryna
Published: August 2023

In order to overcome the reasons for the environmental tax not fulfilling its compensatory, stimulating and fiscal functions, the need to study the problems of environmental taxation through the prism of the growth of the shadow economy and corruption in Ukraine is argued. The established relationships "shadow economy - corruption - environmental regulation - environmental pollution" are summarized and analyzed. A comparison of the volume of environmental taxes in Ukraine, environmental tax as a % of GDP in EU countries and Ukraine was made.

The nature of shadow factors and the consequences of their impact on environmental taxation have been studied. A chain model was built to identify shadow processes in the mechanisms of assessment, settlement, distribution and development of environmental tax in Ukraine. It allows to identify and structure the nature of the appearance of shadow factors at various links of the chain: economic, political, regulatory, organizational, regulatory, budgetary.

The most used shadow operations in environmental taxation are: evasion of payment of environmental tax to the budget due to lack of unified accounting of polluting economic entities; unreliability of data on the volume of emissions and their generalization; transfer of economic activity to the informal sector; corruption schemes when obtaining permits for emissions of pollutants and licenses for handling hazardous waste; untargeted distribution of environmental tax funds between the levels of the budget system; corrupt actions regarding the use of environmental tax.

It was determined that at the current stage, it is necessary to make appropriate management decisions at the state level to counter informal processes in the mechanisms of assessment, settlement, distribution and development of the environmental tax in Ukraine. The chain model of identification of shadow factors will allow a comprehensive analysis of the areas of state policy that require improvement and normative and regulatory changes to prevent informal processes in environmental taxation in Ukraine.
COMPARATIVE ANALYSIS OF APPROACHES TO WORLD CONCEPTS: SPOD SOCIETY, VUCA SOCIETY AND BANI SOCIETY
Authors: Zakharov Yevhenii
Published: August 2023

The author of this study conducts a comparative analysis of several modern approaches to world concepts that replaced each other. Such concepts of the world include: SPOD society, VUCA society and BANI society. Starting proposed research with the description of each approach, the author gradually understands their essence by revealing their abbreviation, where each letter carries a certain meaning of the concept. SPOD is an acronym that characterizes a steady, predictable, ordinary and defined world and the society that lives in it. In 1987, the fundamentally new concept of VUCA society, which is characterized by a volatile, uncertain, complex, ambiguous state of the world replaced the SPOD of society. The next concept – BANI concept of society became relevant after loud, total events – with the onset of the pandemic period of COVID-19 in 2020 and people deciphered it as a brittle, anxious, non-linear and incomprehensible world (when the world had not previously faced a pandemic of this scale), despite the fact that the signs of VUCA society also remained present in the world. The specific characteristics of the subject, object and purpose of the scientific article determine the choice of research methods. To study approaches to world concepts, the author used the method of generalization, analysis and synthesis, classification methods, comparative analysis, inductive and deductive methods for the author to generalize the obtained data.. After conducting research, the author of article comes to the certain conclusions that the above approaches (namely SPOD, VUCA and BANI) are rather a reaction to events that occurred in one or another period of time than actual solutions. The benefit of this research lies in its informativeness, generalization of approaches to world concepts. The information from this research allows companies to better understand the world in which they live and the society in which they do business.
Bank Governance, Asset Quality, and Risk. Do Macro-Prudential Policy and Macroeconomic Factors Matter? Evidence from Nigeria’s Banking Sector
Authors: Agha Eze , Oluyombo Onafowokan , Aworinde Olalekan
Published: August 2023

Purpose: This study examines the nexus between bank governance, asset quality, and banking risk measured by the distance to default (DTD) and their interactions with prudential policy and macroeconomic factors.
 
Theoretical framework: This study uses the Resource Based View (RBV) lens to examine how banks use their unique resources, asset, competencies, and governance framework to mitigate the adverse impact of risks and navigate regulatory policies and macroeconomic variables. The RBV provides context on banks’ unique resources to optimise their long-term objectives in a complex economic landscape.
 
Design/Methodology/Approach: The study analyses panel data from 12 listed banks on the Nigeria Stock Exchanges (NGX) from 2008 to 2021. This study tests autocorrelation, heteroskedasticity, and cross-sectional dependence to validate the study’s analysis. Based on various diagnostic tests, the Feasible Generalised Least Squares (FGLS) are suitable for hypothesis testing.
 
Findings: The findings revealed that bank governance interaction with asset quality has a negative and insignificant impact on bank risk. And liquidity, interest rate, inflation and gross domestic product are significant determinants of banking risk.
 
Research, practical & social implications: Maintaining effective bank risk management requires adherence by all stakeholders to macro-prudential policies by monetary policymakers and macroeconomic factors from the fiscal policymakers.
 
Originality/Value: This study empirically examines bank governance, asset quality, and banking risk in a developing country, incorporates macro-prudential policies and macroeconomic factors, and uses the DTD metric for risk assessment rarely used in related studies in developing countries.

Published: August 2023

The purpose of this study is to substantiate the possibility of successful organ-preserving management tactics for placenta accretion based on the study of a clinical case. We studied the results of examination and treatment of a pregnant woman, a woman in labor and a maternity ward, 32 years old, who received medical care in inpatient conditions at the Perinatal Center of the V.D. Seredavin State Medical University. It can be assumed that the cause of the abnormal attachment of the placenta in this patient could be an infection, in particular, chronic endometritis. This is evidenced by the premature rupture of the fetal membranes, the cause of which is most often an infectious factor. Diagnosis of anomalies of placental attachment is based on the data of instrumental studies. It should be detected in the antenatal period with ultrasound. Despite the presence of placenta accretion, this pathology, unfortunately, was not detected at the stage of pregnancy, which would make it possible to draw up a plan for pregnancy and childbirth in accordance with the tactics recommended for this pathology. In this clinical case, an additional placental lobule isolated from the main part of the placental tissue apparently grew in, which made it possible to avoid massive bleeding in the postpartum period before attempting to separate this part. Careful observation of the patient in the postpartum period with dynamic ultrasound control allowed the diagnosis of placental ingrowth. With diagnostic hysteroscopy, the diagnosis was confirmed, an organ-preserving operation was performed: hysteroesectoscopy with electrosurgical resection of placenta increta. During the control examination, no pathology of the myometrium was detected. It is necessary to take into account the presence of all causes that can lead to abnormalities of placental attachment, in particular, an infectious factor. Active identification of risk factors and early diagnosis of placental abnormalities are the main conditions in the prevention of massive obstetric bleeding and reduction of maternal mortality rates. It is necessary to strive to perform organ-preserving surgical interventions, if there are conditions that ensure their implementation. In this clinical case, despite the presence of a difficult-to-diagnose variant of placental ingrowth, it was possible to perform an organ-preserving operation and preserve the patient's ability to realize reproductive function in the future.

The aim of the work was to assess the advantage of therapeutic measures in children with a stooped back against the background of dysplastic processes, based on the stabilometric method of examination. From 2013 to 2023, the examined patients were registered at the dispensary. The groups are presented as follows: 132 patients – the main group, 122 patients – the comparison group. At the beginning of the follow-up, the age was 5.5±0.7 years. Patients of the two groups were offered back massage No. 10 1 time in 4 months for 20 minutes, physiotherapy, electrical stimulation of the muscles of the paravertebral No. 10 1 time in 6 months, a therapeutic and physical training complex to strengthen the muscles of the anterior abdominal wall and back.
Patients of the main group were additionally recommended exercises on the "Swedish wall", swimming in the water, group classes at the educational school of health "Posture Correction", dosed individual corseting, additional courses of physiotherapy treatment. Based on the results of computer stabilometry in children with incorrect posture against the background of dysplastic manifestations, we note that during the dynamic observation in patients of the main group, the parameters were statistically better than in the comparison group. Physiological posture, a developed muscular corset were formed, and the number of complications significantly decreased. This was not noted in the comparison group (p<0.001). According to computer stabilometry, it was found that the equilibrium function for all statbilometric indicators improved significantly after comprehensive rehabilitation treatment. In patients in the comparison group who were prescribed standard treatment, changes in stabilometric parameters were statistically lower, unreliable, and had negative dynamics. The main criteria for stabilometric evaluation of the effectiveness of treatment are a decrease in the displacement of the center of pressure of the feet, an improvement in the quality of the balance function. During the stabilographic examination after 12 months from the start of classes, positive dynamics (normalization of the projection of the center of gravity relative to the area of support) in children who were engaged in complex functional programs was noted in 49.3% of patients. In children who were engaged in standard schemes, positive dynamics was noted in 15.6% of patients (p<0.001).
In the process of dispensary observation, the parameters of the stabilometric method in children were evaluated. The expediency of prescribing therapeutic measures in the main group of patients has been proved.

Chronic gastroduodenitis (CGD) is one of the most common diseases in children. Current data on the prevalence and incidence of CGD in children are contradictory. Currently, no work has been carried out to assess the prevalence and incidence of CGD in a multicenter study in Russia. The aim of the study was to assess the prevalence of CGD in terms of prevalence using meta-analysis among children aged 0-17 years living in the city of Yaroslavl and large districts of the Yaroslavl region. The research material was the indicators of statistical reporting of medical institutions of the region for 2017-2021. At the same time, the figures are higher than the data of local works on the territory of the Russian Federation. According to our study, the cumulative incidence at the end of 2021 ranged from 7.3% to 11.4% in some districts of the Yaroslavl Region of the Central Federal District, while in some age subgroups this figure exceeds 16%. CGD is a common disease of the upper digestive tract (UDT) in children living in the studied territories (from 15% to 26%). At the same time, in the age groups of 6-7 years and 13-14 years, this indicator exceeds the average value in all the studied territories, and in some it exceeds 53%, which reflects the insufficient level of effectiveness of clinical diagnostic programs for the early detection of CGD in children and will further increase the prevalence of CGD in the general population, especially among children from 3 to 14 years old.

This article discusses the impact of the use of information and communication technologies on the educational process of learning foreign vocabulary. The educational and experimental work carried out with a group of students is presented, in the process of which online services and applications were introduced. During the study, the online service Quizlet was chosen. In conclusion, the results of the study are presented and analyzed, according to which the conducted educational experimental work demonstrates successful results in the development of certain lexical units and grammatical rules in a short time. On average, students increased their results by 16% compared to the initial test - the percentage of positive answers of students in the initial test varies from a minimum value of 40% to a maximum of 70%. According to the results of the first lesson, it can be noted that 67% of students have successfully mastered new lexical units. About 73% of students completed the final test with between 60% and 80% correct answers. These results indicate that the use of interactive services in the learning process is an effective method for learning foreign languages, since such programs use algorithms that affect all types of memory, which leads to more successful consolidation of lexical units, and the use of the Quizlet application in the educational process helps to increase the motivation of students, and thanks to the variety of exercises that this service offers, the process of learning a foreign language becomes simpler and more effective. It can be said with confidence that the use of information and communication technologies in the study of foreign languages significantly improves the formation and development of students' speech skills.
