Ligand-Metal Cooperation Enables Net C–C Activation Cross-Coupling Reactivity of Cyclopropyl Ketones
Authors: Gilbert Michael , Trenerry Michael , Longley Victoria , Castro Anthony , Berry John , Weix Daniel
Published: July 2023

Reactions that cleave C–C bonds and enable functionalization at both carbon sites are powerful strategic tools in synthetic chemistry. Stereodefined cyclopropyl ketones have become readily available and would be an ideal source of 3-carbon fragments, but general approaches to net C–C activation / difunctionalization are unknown. Herein we demonstrate the cross-coupling of cyclopropyl ketones with organozinc reagents and chlorotrimethylsilane to form 1,3-difunctionalized, ring-opened products. A combination of experimental and theoretical studies rule out more established mechanisms and shed light on how cooperation between the redox-active terpyridine (tpy) ligand and the nickel atom enables the C–C bond activation step. The reduced (tpy•–)NiI species activates the C–C bond via a concerted asynchronous ring-opening transition state. The resulting alkylnickel(II) intermediate can then be engaged by aryl-, alkenyl-, and alkylzinc reagents to furnish cross-coupled products. This allows quick access to products that are difficult to make by conjugate addition methods, such as β-allylated and β-benzylated enol ethers. The utility of this approach is demonstrated in the synthesis of a key (±)-taiwaniaquinol B intermediate and the total synthesis of prostaglandin D1.

Authors: Silswal Akshay , Pramanik Anup , Koner Apurba Lal
Published: July 2023

The dysfunctions in the mitochondria are associated with various pathological conditions like neurodegeneration, metabolic disorder, and cancer, leading to dysregulated cell death. Here, we have designed and synthesized a julolidine-based molecular rotor (JMT) to target mitochondria with far-red emission accounting for mitochondrial dysfunction. JMT showed an excellent viscosity sensitivity with 160-fold and 4-times enhancement in fluorescence intensity and lifetime, respectively. The origin of the dark state in a lower viscous environment was investigated through density functional calculations. JMT has monitored mitochondrial dysfunction under stressed and inflammatory conditions. Moreover, we reported tracking small fluorescent molecules switching from mitochondria to the plasma membrane. On treating the mitochondria potential uncoupler, JMT relocates to the cell membrane and can be utilized for understanding the interplay between mitochondria and cell membranes.

Morphology of the bladder wall in idiopathic feline cystitis
Authors: Letkin Alexander Ilich , Bikeeva Elizaveta Nikolaevna
Published: July 2023

In feline idiopathic cystitis, morphological changes were found mainly in the mucosa and submucosal layer of the bladder wall. They are characterized by hyperplasia and congestion of blood vessels. Morphometric assessment of the main structures of the bladder wall in cats with idiopathic cystitis revealed an increase in the thickness of the mucous membrane due to a decrease in the thickness of the submucosal layer and muscular membrane. When using anti-stress therapy on the 14th day from the start of treatment, a decrease in a similar indicator was observed due to an increase in the thickness of the submucosal layer and muscle membrane. In control cats, after the application of the generally accepted treatment regimen, the processes of regeneration of the bladder wall were insignificantly expressed.

Published: July 2023

Autoclaves are vital equipment in the hospital sterilization processes. They are so important in any hospital center that a failure in the equipment can result in the total suspension of surgical activity, as they represent the main tool when it comes to prevent the spread of infections to which medical procedures are exposed [1]. Vacuum pumps are essential elements in the operation of autoclaves, since a successful sterilization process depends on their performance. This article intends to introduce a method to automatically detect the failure condition of an autoclave's vacuum pump, based on the characteristics of the acoustic signal produced by the equipment during its operation. Initially, the acoustic signals emitted by the pump in both normal and failure conditions were captured. The results obtained by different signal analysis methods were compared, and it was determined which of them ended up being more suitable in order to perform a diagnosis of the equipment's operating condition. The results obtained showed that, in order to identify the specific type of failure analyzed, the analysis within the time domain ended up being more suitable than the analysis within the frequency domain. Finally, an algorithm that detects the presence or absence of water in the vacuum pump of the autoclave was obtained.
Banach’s theorem in higher-order reverse mathematics
Authors: Hirst Jeffry L. , Mummert Carl
Published: July 2023

In this paper, methods of second-order and higher-order reverse mathematics are applied to versions of a theorem of Banach that extends the Schröder–Bernstein theorem. Some additional results address statements in higher-order arithmetic formalizing the uncountability of the power set of the natural numbers. In general, the formalizations of higher-order principles here have a Skolemized form asserting the existence of functionals that solve problems uniformly. This facilitates proofs of reversals in axiom systems with restricted choice.

Published: July 2023

Due to the post-pandemic, madrasahs need effective literacy strategies to cope with the challenges posed by the situation. While some madrasahs may have implemented these strategies, they may be constrained by common issues. This study aims to analyze blended literacy activities to improve the literacy program at Integrated Madrasah Tsanawiyah after the Covid-19 pandemic. This research used a qualitative approach with a case study type. Data were collected through observation, interviews, and documentation. The data was analyzed by organizing, reducing, and interpreting data. Based on the study results, it is evident that the blended literacy strategy used at Integrated Madrasah Tsanawiyah combines offline activities (print-based and face-to-face) and online activities (technology and internet-based) in student literacy activities, both within and outside the madrasah to improve the quality of madrasah literacy. This study can provide a framework for other madrasahs or educational institutions to develop their blended activities literacy programs, particularly during times of crisis when traditional teaching methods may not be feasible.

Background

Obesity is a significant worldwide health problem that is linked with mental health. The elucidation of the possible overlapping biochemical mechanism(s) involved in inflammation and oxidative stress is imperative to better understand and address obesity and related metabolic disorders. The aim of the study was to investigate the associations between inflammatory and oxidative stress profiles with parameters that reflect metabolic, emotional, and mental health in a Greek metabolically unhealthy obese cohort.

Methods

In total, 122 metabolically unhealthy people with obesity were recruited. Anthropometric measurements, biochemical, inflammatory and oxidative stress markers were assessed. Quality of life was evaluated through questionnaires for insomnia, self-esteem, depression, physical and mental health.

Results

The inflammatory biomarker tumor necrosis factor-alpha (TNF-α) and the ratio oxidized low-density lipoprotein/low-density lipoprotein (oxLDL/LDL) were higher in hypertensive (p=0.002, p=0.001 respectively) and hyperglycemic subjects (p=0.017, p=0.001 respectively). Furthermore TNF-α (p<0.001), oxLDL/LDL (p<0.001) and oxLDL/high-density lipoprotein (HDL) (p=0.016) increased significantly with the increase of metabolic syndrome components. Finally, a negative association between interleukin-6 (IL-6) and Rosenberg Self-Esteem Scale (Beta=-0.019, p=0.019) and a positive association between TNF-α and the Center for Epidemiologic Studies Depression Scale Revised (Beta=0.003, p=0.015) were found.

Conclusions

The results of the study suggest that obesity-related systemic inflammation is associated with worse self-esteem and depression symptoms, indicating an overlapping mechanism which can be utilized to the management of obesity.

Published: July 2023

Objective

The specific effect of Adipose-Derived Mesenchymal Stem Cells (Ad-MSC) on acute joint inflammation, where the response mostly depends on innate immunity activation, remains elusive. The pathogenesis of gouty arthritis, characterized by the deposition of monosodium urate (MSU) crystals in the joints, associated to acute flares, has been associated to NLRP3 inflammasome activation and subsequent amplification of the inflammatory response. Our aim was to study the effect of human Ad-MSC administration in the clinical inflammatory response of rabbits after MSU injection, and the molecular mechanisms involved.

Methods

Ad-MSC were administered by intraarterial route shortly after intraarticular MSU crystal injections. Joint and systemic inflammation was sequentially studied, and the mechanisms involved in NLRP3 inflammasome activation, and the synthesis of inflammatory mediators were assessed in the synovial membranes 72h after insult. Ad-MSC and THP-1-derived macrophages stimulated with MSU were co-cultured in transwell system.

Results

A single systemic dose of Ad-MSC accelerated the resolution of local and systemic inflammatory response. In the synovial membrane, Ad-MSC promoted alternatively M2 macrophage presence, inhibiting NLRP3 inflammasome and inducing the production of anti-inflammatory cytokines, such as IL-10 or TGF-β, and decreasing nuclear factor-κB activity. Ad-MSC induced a net anti-inflammatory balance in MSU-stimulated THP-1 cells, with a higher increase in IL-10 and IDO expression than that observed for IL-1β and TNF.

Conclusion

Our in vivo and in vitro results showed that a single systemic dose of Ad-MSC decrease the intensity and duration of the inflammatory response by an early local COX-2 upregulation and PGE2 release. Ad-MSCs suppressed NF-kB activity, NLRP3 inflammasome, and promoted the presence of M2 alternative macrophages in the synovium. Therefore, this therapeutic approach could be considered as a pharmacological alternative in patients with comorbidities that preclude conventional treatment.
Double burden of malnutrition and its associated factors among adolescents in Debre Berhan Regiopolitan City, Ethiopia: a multinomial regression model analysis
Authors: Getacher Lemma , Ademe Beyene Wondafrash , Belachew Tefera
Published: July 2023

Background

The double burden of malnutrition (DBM), contained both undernutrition and overnutrition, is a growing public health concern that presents a significant challenge to the food and nutrition policies of developing nations such as Ethiopia. However, the prevalence and contributing factors of DBM among adolescents in the study area have not been adequately investigated by Ethiopian researchers. Therefore, this study aims to determine the prevalence of DBM and contributing factors among secondary school students in Debre Berhan City, Ethiopia.

Methods

A school-based cross-sectional study was conducted among 742 adolescents aged 10–19 years from October 13, 2022, to November 14, 2022, using a multi-stage sampling method. Data were collected using the online Kobo toolbox tool. A multinomial logistic regression model was used to analyze the data. The data were cleaned and analyzed in R software 4.2.2. Adolescents who had body mass index for age Z score (BAZ) < −2 SD, > +1 SD, and > +2 from the median value were considered thin, overweight, and obese, respectively.

Results

The overall prevalence of DBM was 21.5% (14.8% thinness and 6.7% overweight/obesity). In the multivariable multinomial logistic regression analysis models factors such as age [AOR = 0.79, 95% CL: (0.67, 0.93)], sex [AOR = 3.86, 95% CL: (2.35, 6.32)], school type [AOR 5.03, 95% CL: (2.30, 10.99)], minimum dietary diversity score [AOR = 2.29, 95% CL: (1.27, 4.14)], frequency of meals [AOR = 2.09, 95% CL: (1.13, 3.89)], home gardening practice [AOR = 2.31, 95% CL: (1.44, 3.67)], history of illness [AOR = 0.57, 95% CL: (0.36, 0.93)], and knowledge of nutrition [AOR = 4.96, 95% CL: (1.61, 15.33)] were the significant predictors of either thinness or overweight/obesity (DBM).

Conclusion

More than one-fifth of adolescents were affected by DBM in the study area. This prevalence is higher compared with the national and regional prevalence that found to be a public health concern. Thus, interventions like double-duty interventions should consider the age, sex, school type, minimum dietary diversity score, frequency of meals, home gardening practice, history of illness, and nutritional knowledge of adolescents.

Published: July 2023

Multisystem inflammatory syndrome in children (MIS-C) has been widely reported, mainly in Western countries. The clinical features of MIS-C and Kawasaki disease are similar. The latter is common in Asian countries, including Japan. Meanwhile, the incidence of MIS-C seems to be low in Japan. Retropharyngeal edema is relatively common in older patients with Kawasaki disease and has been reported in a few patients with MIS-C. We describe a case of severe retropharyngeal edema after coronavirus disease 2019 (COVID-19) that improved quickly with high-dose of intravenous immunoglobulin treatment. Onset of retropharyngeal edema was 3 weeks after COVID-19. The patient received appropriate intravenous antibiotics for 5 days, but his symptoms worsened. Therefore, we suspected that his retropharyngeal edema was caused by suspected MIS-C even though he did not have the typical clinical symptoms of suspected MIS-C such as gastrointestinal symptoms and shock. Retropharyngeal edema was refractory to antibiotic therapy but lessened quickly with high-dose immunoglobulin therapy, without other typical clinical manifestations of MIS-C, suggesting that early immunoglobulin therapy might prevent the progression of MIS-C.

A strongly felt need for a multipurpose and simple-to-use computer language emerges as more and more institutional research offices acquire computer terminals. A veritable Babel of computer languages exists (Ryland, 1979), and a good deal of thought should be given to choosing the right language. Learning a computer language represents a significant investment in time and effort, and because of the problem of training new staff when turnover occurs, only one or, at most, two languages should be introduced into an office. The state of the art in languages has progressed far enough that, in most instances, institutional researchers need not become full-fledged computer programmers in order to access computer data. many of the high-level languages have taken the drudgery out of programming, and having the computer do much of the data manipulation takes the drudgery out of institutional research.

Published: July 2023

This study was carried out to determine the effects of different supplemental irrigation (SI) treatments on yield, yield components, and some drought-related traits in eight wheat varieties grown in the semi-arid environment of Jordan. Two SI treatments were used in addition to the control (i.e. rainfed treatment with 262.8mm accumulated rains): partially SI treatment (PSI=262.8mm rains+220mm irrigation at anthesis stage) and continuous SI treatment (CSI= 262.8mm rains + 377.5mm at 2-3 weeks intervals during different stages of wheat growth). Seven durum wheat varieties; namely Sham1, Omqais, Acsad65, Bani Suef6, Bani Suef4, Horani Nawawi, and Dairalla6 in addition to one bread wheat variety (Ammon) were included in this study. Yield and yield components were significantly increased and the time required to anthesis and maturity were delayed by SI. PSI treatment significantly increased grain yield by 50.2%, while CSI increased yield by 121% as compared to the control treatment. Considerable variations among varieties were observed under different irrigation treatments. Sham1 (2266.7 kg ha-1), Omqais (2253.3 kg ha-1), and Acsad65 (1963.3 kg ha-1) gave the highest grain yield under control treatment with low drought susceptibility indices, implying their low grain yield losses under control as compared with SI treatments with high genetic potentials for drought tolerance. The top-yielding varieties under CSI were Acsad65 (4716.7 kg ha-1), Dairalla6 (4586.7 kg ha-1), Bani Suef6 (4460 kg ha-1), and Omqais (4360 kg ha-1). Under PSI, Sham1 (3303 kg ha-1) followed by Dairalla6 (3193.3 kg ha-1), Horani Nawawi (3130 kg ha-1), and Bani Suef6 (3026.7 kg ha-1) gave the highest grain yield. All yield components (number of kernels per spike, number of tillers, and grain size) significantly contributed to increasing grain yield under SI. In conclusion, SI under rainfed conditions improves yield-attributing traits, which led to a substantial increase in grain yield. It would be possible to increase GY by more than 3 and 4 tonnes ha-1 with PSI and CSI, respectively.

Published: July 2023

У статті схарактеризовано психолого-педагогічні компоненти освітнього простору як провідної умови формування в курсантів-пілотів компетентності самотворення. Аналіз теоретичних підходів дозволив сформувати науковий погляд на освітній простір у системі професійної освіти майбутніх авіаційних фахівців. Основний зміст уможливив обґрунтування компетенції самотворення як умови, що передбачає взаємообумовленість та взаємодоповнюваність усіх компонентів навчальної діяльності, основою якої є  курсант, здатний змінити себе через компетентність. Саме курсант засвоює, інактивує для себе власний світ, конструює свій освітній простір, забезпечуючи у такий спосіб безперервне професійне й особистісне вдосконалення. Спроможність курсанта до саморуху в навчальній діяльності  за схемою «навчальні заняття – самостійна робота – навчальна самодіяльність – автодидактичні навички» дозволяє стверджувати про здатність особистості проявляти свою самостійність, адекватно співвідносити власні інтенції й потенції із характером та складністю проблемної ситуації, обирати відповідні методи щодо її вирішення, бути готовим нести відповідальність за свої дії. Саме означене вище є основним напрямом виникнення у свідомості курсанта мети особистісного й професійного вдосконалення як інструменту трансформації власної особистості в суб’єкта самотворення.

Наголошено, що успішність курсанта в самотворенні  постає через здатність до конструювання освітнього простору й оволодіння відповідним алгоритмом, завдяки якому здобувач освіти відчуває владність над своїми здібностями й особливостями психіки, власну компетентність у самоорганізації навчальної діяльності та самотворенні.
Development of the Smart Specialisation Concept: Theoretical Aspects
Authors: Shvets N.
Published: July 2023

The article examines the development of the concept of smart specialisation with determination of the sequence and directions of evolutionary changes, reveals the essence of the concept of smart specialisation and provides the results of its terminological analysis.
The article shows the growing popularity of the smart specialisation concept in the world, which is confirmed by the data on the frequency of use of the term “smart specialisation” in the global Internet space and the number of published works included in the Scopus database for the period 2011-2022. The prerequisites and sequence of conceptualisation of smart specialisation as a new management approach in the system of regional governance of the EU member states are established.
The article analyses a selection of scientific and methodological publications by developers and promoters of the smart specialisation concept and concludes that its theoretical and methodological development is in three main directions: specification of the process methodology, political deployment and instrumental direction.
Based on the results of the terminological analysis, the essence of smart specialisation is clarified, including consideration of its semantic foundations – “smart” and “specialisation”. Attention is focused on the change in the subject area of specialisation with the development of the concept of smart specialisation. The author’s vision of the conceptual relationship between the concepts of smart specialisation and diversification is presented. It is concluded that it is advisable to use the latter in two aspects: as a component of the smart specialisation process and as its result.
Based on the results of the analysis and study of the development of the concept of smart specialisation, five semantic constructions of smart specialisation are allocated, which reveal the content of this polysemic term in various aspects, namely, the smart specialisation approach, the smart specialisation process, the smart specialisation strategy, the smart specialisation policy and the smart specialisation as a tool. The essence of these concepts and a certain logical connection between them are revealed.
The author makes a conclusion about the role and importance of smart specialisation for the Ukrainian economy as a tool for uniting regional stakeholders, developing innovative ecosystems and interregional and cross-border partnerships, and attracting investments to ensure the recovery and development of the national economy on an innovative basis.
Uncertain random problem for multistage switched systems
Authors: Liu Guangyang , Chang Yang , Yan Hongyan
Published: July 2023

Optimal control problems for switched systems how best to switch between different subsystems. In this paper, two kinds of linear quadratic optimal control problems for multistage switched systems composing of both randomness and uncertainty are studied. Chance theory brings us a useful tool to deal with this indeterminacy. Based on chance theory and Bellman's principle, the analytical expressions are derived for calculating both the optimal control input and the optimal switching control law. Optimal control is implemented by genetic algorithm instead of enumerating all the elements of a series of sets whose size grows exponentially. Finally, the results of numerical examples are provided to illustrate the effectiveness of the proposed method.

Günümüzde ülkelerin gelişmişlik düzeylerine ilişkin tüm sınıflandırmalarda enerji önemli bir yer tutmaktadır. Ülkelerin geleceğe yönelik yaptığı bütün planlamalarda enerji kullanım oranı etkin bir parametre olarak göz önüne alınmaktadır. Buna bağlı olarak enerji kullanımının düşürülmesi amacıyla yapılan bilimsel çalışmalar önem kazanmaktadır. Bu çalışmada, ara kat döşemelerinde yalıtım ve faz değiştiren malzeme (FDM) kullanılmasının enerji verimliliği ve konfor koşulları üzerindeki etkileri incelenmiştir. Bodrum, zemin ve iki normal kattan oluşan örnek bir binada eş zamanlı olarak ısıtılan ve ısıtılmayan ortamlardan oluşan farklı senaryolar üzerinde çalışma yapılmıştır. Bu senaryolarda yalıtımsız, yalıtımlı ve yalıtıma ek FDM içeren bir katmanın olduğu üç farklı döşeme tipi kullanılarak, bu parametrelerin ortamların ısı yüklerine, ortam sıcaklığına ve enerji kullanımına etkileri incelenmiştir. Çalışmada elde edilmiş olan bulgulara göre; döşeme ve tavanda yalıtım ve FDM kullanılması ile ortamların ısı yükü düşmektedir. Aynı zamanda ortam sıcaklıklarının ayar sıcaklığına daha yakın olması ile birlikte ısıl konfor koşullarının iyileşmekte olduğu belirlenmiştir. Çalışma sonuçları göstermektedir ki; döşeme ve tavanlarda yalıtım ve FDM kullanımı, yıllık enerji kullanımını aşağıya çekmekte ve enerji verimliliğinde önemli bir artış sağlamaktadır.

Published: July 2023

"This study was conducted for the retail trade; approaches to determining changes in retail trade under the influence of digitalisation of socio-economic processes were established. The purpose of the research was to analyse the vectors of digitalisation in the field of digital trade in Ukraine. The main methods used in the study were analysis, deduction, forecasting, abstraction, modelling, etc. The study analysed the main factors influencing the development of digital transformation in Ukraine. Using the developed model, it was demonstrated that technological and behavioural factors have the greatest impact; they force retailers to actively adapt to the environment and find new methods of introducing innovations into their business models. Other factors, such as socio-economic or institutional, have a much smaller impact on retail innovation. In addition, the study evaluates the interdependence of consumer needs and relevant innovations in the field of innovation and describes how certain companies have used the latest technologies to improve the quality of their business."

Authors: Raslin Harvin
Published: July 2023

Latar belakang dari penelitian ini terdapat beberapa kendala terhadap kondisi bangunan Polsek dalam memberikan pelayanan prima kepada masyarakat dan menunjang kinerja Polri. Dalam membahasnya, dilakukan melalui pendekatan kualitatif dan kuantitatif serta pendekatan Teori Evaluasi dan Pelayanan Prima. Proses pengumpulan data dilakukan dengan metode Focus Group Discussion (FGD), pengisian kuesioner, wawancara dan observasi. Responden yang disasar berasal dari anggota Polri Tingkat Polres dan Polsek. Lokasi penelitian sebagai uji petik terdiri dari 10 (sepuluh) Polda dan 1 (satu) Polsek untuk masing-masing Polres. Sedangkan obyek penelitian berupa struktur dan non struktur bangunan Polsek (aspek fasum dan fasos).Pelaksanaan penelitian dilakukan mulai tanggal 8 Februari s/d 11 Maret 2021 dengan melibatkan Peneliti Puslitbang Polri  dan mitra sebagai Konsultan yaitu Slog Polri, Universitas Indonesia (UI), Badan Penerapan dan Pengkajian Teknologi (BPPT) dan PT Rekacipta Kreasindo. Dari pelaksanaan penelitian ini telah ditemukan beberapa kendala terkait struktur dan non struktur bangunan Mako Polsek yang kurang selaras dengan standar dan kelayakan mutu bangunan. Dan kendala tersebut dirumuskan beberapa rekomendasi untuk peningkatan mutu dan standar bangunan.Berdasarkan temuan dari sampel uji petik terlihat bahwa mayoritas bangunan Mako Polsek yang dikunjungi tidak memenuhi persyaratan konstruksi yang aman, terutama pada Polsek yang dibangun 15 tahun lalu atau sebelumnya. Bangunan Polsek yang lama tersebut juga banyak yang tidak memiliki sertifikat dan IMB. Kondisi fasilitas umum dan sosial terlihat sudah cukup memadai, namun dapat ditingkatkan lagi misalnya dengan lebih memperhatikan fasilitas untuk warga dengan disabilitas. Hal lain yang perlu diperhatikan adalah standardisasi pemasangan CCTV dan jaringan internet, serta penyesuaian anggaran harwat untuk pemeliharaan rutin bangunan.
