Recent Advances in Direct Pyridine C-H Activation Strategies
Authors: Roy Sushmita
Published: January 2023

Background:

Pyridine is one of the most ubiquitous hetero-aromatic moieties in pharmaceutical chemistry and it has enormous importance in a plethora of fields. From a synthetic chemistry standpoint, pyridine moiety has been used as a directing group in C-H activation strategies to functionalize various rings. However, this unique feature to participate as a directing group hinders developing methodologies to carry out C-H activation on the pyridine ring itself. One of the simplest solutions is to block the activity of ring nitrogen at the cost of two extra steps. Here, in this review, along with the blocking, we will briefly mention some interesting ways to get around this problem and the remaining challenges ahead.

Objective:

The coordinating ability of pyridine N poses a big challenge toward C-H functionalization on the pyridine ring. This review summarizes some of the recent methods towards this challenge.

Method:

Some key ideas towards that goal have been described. Here, the C-H activation strategies are categorised as follows: (1) Pyridine N-oxide mediated C-H activation, (2) Dimerization of C-H activation of pyridine, (3) Direct Pyridine C2-H activation, (4) Direct Pyridine C3-H activation and (5) Direct Pyridine C4-H activation.

Results:

Several methods have been highlighted that can be utilised to prepare C-H functionalized products with regiospecificity that subsequently may be manipulated into interesting products which are difficult to attain easily.

Conclusion:

This review explores various new direct C-H activation methods on pyridine which attempts to fill the void of traditional synthetic protocols in regard to regioselective pyridine functionalization. This review also explores the limitations of current methodologies which must be wiped off to attain a mature state in need of the pharmaceutical industry.
Parasites as Metal Corrosion Inhibitors, New Achievements
Authors: Rassouli Maryam , Azadi Mahboobeh
Published: January 2023

Green inhibitors for metal corrosion were mostly known as plant extracts but in the series of
studies, parasites had some active biomaterials that inhibited metal corrosion. The extracts of different
parasites, tick (Hyalomma), fly larva (Oestrus), and leech (Hirudo) were used in acidic media for metal
corrosion inhibition. Total proteins of Hyalomma and Hirudo were also extracted and used for the investigation
of protein role in metal corrosion inhibition. In extract examinations, parasites can be candidates
for green inhibition of metal corrosion. During the experiment processes, the collagen of Hirudo was
dissolved and the chitin of arthropods was also dissolved to chitosan and coated the metal surfaces. In the
extracted proteins examinations, the corrosion inhibition of Hirudo was much better than Hyalomma.
According to different research, arthropods (as chitin-rich) and leech (as collagen-rich) parasites could
inhibit metal corrosion in acidic media, suggesting a bridge between parasitology and engineering.

Authors: Hastuti Sri , Hastuti Sri
Published: January 2023

Abstrack- Food court locations are placed in current visited places and usually many customer tables that are widely scattered there. It can be too slowly and inefficient ordering, both in terms of time and the process of delivering order because of difficulty of finding a customer table. Based on the explanation above, the authors make a design and build a table location information system in the food court using RFID based android applications. This system allows customers to inform the location of the table to food vendors using RFID. In designing hardware devices, a NodeMCU ESP8266 microcontroller is needed and for designing android software applications using APP Inventor. Google Firebase's realtime database platform was chosen to connect hardware and software devices. The measurement results from the design of this system show that the system is capable of producing precise RFID reading output with an accuracy level of 100% according to the location of the buyer's table. Meanwhile, the average delay obtained from this system is 0.81 seconds. This tool can read the RFID card without a barrier as far as 4.1 cm and cannot read the card if blocked by a metal material.Â Keywords: Food Court, RFID, NodeMCU ESP8266, App Invetor2, FirebaseÂ

Various factors also influence this policy, both at the individual level, media routines, organizations, social institutions, and social systemsThis research concludes that the editorial policy is more careful in the function of control and criticism as well as the existence of various factors both at the individual level, media routines, organizations, social institutions, and social systems that underlie these decisions.
The Effect of Prophylactic Intravenous Amiodarone Administration on Reperfusion Ventricular Fibrillation in Patients With Left Ventricular Hypertrophy Undergoing Cardiopulmonary Bypass Surgery: Protocol for a Randomized Double-Blind Clinical Trial
Authors: Zhou Xiaokai , Zhang Zhenfeng , Gong Chanjuan , Fang Yin
Published: January 2023

Background

Ventricular fibrillation (VF) is a common arrhythmia that occurs after the release of aortic cross-clamp (ACC) in patients undergoing cardiopulmonary bypass (CPB) surgery. Repeated defibrillation and long duration of VF could increase myocardial injuries. In patients with left ventricular hypertrophy (LVH), VF is easier to occur and more difficult to be terminated. Amiodarone, known as class III antiarrhythmic agent, has the prominent properties of converting VF and restoring the sinus rhythm. Before ACC release, administration of amiodarone has been confirmed useful to reduce occurrence of VF. However, few studies are focused on the effect of amiodarone before ACC release on reducing VF in patients with LVH.

Objective

This study aimed at determining the efficacy of prophylactic intravenous amiodarone administration on reperfusion VF after release of ACC in patients with LVH undergoing CPB surgery.

Methods

This will be a prospective, randomized, double-blind, placebo-controlled trial. The trial will enroll 54 patients with LVH aged 18-75 years who will undergo CPB surgery. All eligible participants will be randomly allocated to either the amiodarone or placebo group by using the block randomization in a 1:1 ratio. The primary end point will be the incidence rate of VF 30 minutes after ACC release and be assessed using the Fisher exact test. All data will be analyzed in accordance with the intention-to-treat principle.

Results

The study began in August 2022, and the data collection will take place for the next 2 academic years. As of this writing, 21 participants have already been recruited for the study.

Conclusions

With this trial, we are hoping to demonstrate that prophylactic infusion of amiodarone before ACC release could reduce the occurrence of reperfusion VF in patients with LVH.

Background

Medical informatization has initially demonstrated its advantages in improving the medical service industry. Over the past decade, the Chinese government have made a lot of effort to complete infrastructural information construction in the medical and health domain, and smart hospitals will be the next priority according to policies released by Chinese government in recent years.

Objective

To provide strategic support for further development of medical information construction in China, this study aimed to investigate the current situation of medical information construction in tertiary class-A public hospitals and analyze the existing problems and countermeasures.

Methods

This study surveyed 23 tertiary class-A public hospitals in China who voluntarily responded to a self-designed questionnaire distributed in April 2020 to investigate the current medical information construction status. Descriptive statistics were used to summarize the current configurations of hospital information department, hospital information systems, hospital internet service and its application, and the satisfaction of hospital information construction. Interviews were also conducted with the respondents in this study for requirement analysis.

Results

The results show that hospital information construction has become one of the priorities of the hospitals’ daily work, and the medical information infrastructural construction and internet service application of the hospitals are good; however, a remarkable gap among the different level of hospitals can be observed. Although most hospitals had built their own IT team to undertake information construction work, the actual utilization rate of big data collected and stored in the hospital information system was not satisfactory.

Conclusions

Support for the construction of information technology in primary care institutions should be increased to balance the level of development of medical informatization in medical institutions at all levels. The training of complex talents with both IT and medical backgrounds should be emphasized, and specialized disease information standards should be developed to lay a solid data foundation for data utilization and improve the utilization of medical big data.

Arab Journal of Plant Protection, 40(4): 307-314. https://doi.org/10.22268/AJPP-40.4.307314 This study aimed to evaluate the effect of some food sources on some of the biological indicators of the parasitoid Psytalia concolor (Hymenoptera: Braconidae). In the sugar diet, the following sugar sources were used: sucrose and yeast, glucose, fructose, sucrose, honey solution, and the honeydew obtained from the black scale olive insect Saissetia oleae and Euphyllura olivina, and water as control. In the protein diet, the amino acids tryptophan, phenylalanine and proline were used, with a mixture of them and distilled water as control. The results obtained showed differences in the effect of sugar type on the life span of both males and females, and the females' life span were longer than the males' life span in all tested groups, suggesting that the female's food requirements were higher than that of the males to provide energy for maturation and laying eggs. Results obtained also showed that P. concolor females fed on sucrose had lower average life span compared to other tested sugars and solid food. The protein feeding of the P. concolor parasitoid is very important because the females depend on the protein nutrition of the flowers to complete their sexual maturity. Nutrients such as proteins, amino acids and vitamins are also important for the activity and effectiveness of the insect parasitoids . Keywords: Psytalia concolor, glucose, honeydew, amino acids, Proline

Development of new technologies distributing electric power from power stations to our homes through a  network of cables and wires, including numerous electric devices at working places and home environment become a source of electromagnetic radiation (EMR) much stronger than EMR of natural origin. To provide a better understanding of the impact of the EMR of anthropogenic origin on living organisms, we investigated the long-term effects of EMR on Lemna minor. In this study, plants of the L. minor laboratory clone were exposed to low frequency (50 Hz) electromagnetic radiation (LF EMR) growing clones in Petri dishes placed on the coils initially generating magnetic flux (MF) of 1 µT for first three weeks, 2 µT until 12th week and after 12th week of the experiment MF was enhanced up to 300 µT. We exam-ined the response of the plants by sequencing DNA fragments that included promoter, intron, and exon regions of ascorbate peroxidase (APx), glutathione peroxidase (GPx), and catalase (Cat) genes) as well measured growth parameters growth intensity, frond area, and number of fronds. Comparison of growth parameters of L. minor clones exposed to 2 µT and 300 µT magnetic flux revealed positive effect stimulating growth of experimentally affected plants at 2 µT After the first 14 weeks of treatment, the growth parameters were lower in the directly exposed by LF EMR group than in the group grown distantly from the source of EMR. However, after 18 weeks from the beginning of the experiment no significant difference was observed between two groups of L. minor including directly and indirectly affected by LF EMR plants. Moreover, the signals of the impact of LF EMR on the plants as rising of new point mutations were detected. The significantly enhanced number of variations in DNA sequences of L. minor clones directly affected by LF EMR in comparison to indirectly affected clones were revealed at the  introns of APx (P = 0.011), GPx (P = 0.009), and Cat (P = 0.044) genes starting from the 10th week of the experiment In conclusion, the comparison of DNA sequencing data together with measurements of growth parameters revealed differences in response at molecular and physiological levels of directly and indirectly affected L. minor clones providing evidence that response to the impact of LF EMR depended on the prolongation of the impact and the magnetic flux density.

Abstract: Pancreatic cancer is the fourth leading cancer-related cause of death throughout the world. Magnetic resonance imaging (MRI) is typically capable of quickly differentiating cystic from noncystic tumours due to the good soft tissue contrast resolution. Cystic tumours are frequently simple to identify with an MRI; however, non-cystic non-adenocarcinoma tumours can exhibit a wide range of imaging characteristics that may be mistaken for ductal adenocarcinoma. An effective method for identifying pancreatic lesions is MRI. This study investigates the current and recent evidence concerning the role of MRI in the diagnosis and staging of pancreatic cancer. PubMed, Web of Science, Science Direct, EBSCO, and Cochrane library were searched. Study articles were screened by title and abstract using Rayyan QCRI then a full-text assessment was implemented. A total of 7 studies were included, with 618 pancreatic cancer patients with different histopathological types. Most studies reported the benefits of MRI in the diagnosis and staging of pancreatic cancer and in identifying extra-abdominal metastases. Only one study found that MRI understaged the tumor size and did not detect the micro-infiltration of peri-pancreatic tissues. MRI has a significant role in diagnosing and staging pancreatic cancer. There have lately been substantial advancements in pancreatic imaging utilizing multiple imaging modalities, such as SG-KS-4D-MRI and DW imaging with traditional MR.

Published: January 2023

O presente trabalho investiga, a partir de uma perspectiva instrumental de Políticas Públicas, o papel que a tributação pode – ou deve – desempenhar no combate a crises estruturais, especialmente considerando a pandemia gerada pelo coronavírus (COVID-19). Em análise que adota o método hipotético-dedutivo, considera-se que a tributação, enquanto mecanismo de Políticas Públicas, apresenta papel elementar no combate às externalidades negativas geradas pela pandemia, especialmente através do reconhecimento das importantes funções (sobretudo extrafiscais) a serem desempenhadas pela tributação. A Política Tributária Anticíclica, nesse contexto, serve aos propósitos contemporâneos de combate à pandemia. Nessa linha, interessa observar como o Brasil tem refletido – no substrato tributário – para alcançar tal finalidade. Finalmente, o trabalho analisa as recentes medidas tributárias legais e infralegais adotadas para o combate à crise, assim como recentes proposições de leis e propostas oriundas de setores representativos do Fisco, considerando também a experiência dos países membros da OECD com o mesmo propósito.

Published: January 2023

Fuzzy soft set are introduced by author Molodtsov, which is solve imprecise problems in the field of engineering, social science, economic, medical secience and environment. This paper addresses the study of domination in fuzzy soft graphs. By using the concept of strength of a path, strength of connectedness and strong arc, domination set is established. The necessary and sufficient condition for the minimum domination set of FSG is investigated. Further some properties of independent domination number of FSG are obtained and the proposed concepts are described with suitable examples. Finally, we state and prove some results related to these concepts.

Optimal Control of Customers to the Service Facility with Two Types of Customers
Authors: P. Maheswari  , C. Selvakumar  , C. Elango
Published: January 2023

In this article, we considered a discrete-time service facility system, viewed as a Markov Decision Process (MDP). Decisions are taken at discrete time epochs to control admissions to the system. Here the queue before the server is divided into eligible queue and potential queue. Potential queue has two types of customers (Priority and nonpriority). It is assumed that demands arrived throughout the period but they are satisfied only at the end of the period. The MDP based on average cost criteria is used to find the optimal policy to be implemented for the system. Numerical example is provided to illustrate the problem.
On Two Arithmetic-Geometric Banhatti Indices of Certain Dendrimer Nanostars
Authors: V.R.Kulli
Published: January 2023

Chemical Graph Theory is a branch of Mathematical Chemistry whose focus of interest is to finding topological indices of chemical graphs which correlate well with chemical properties of the chemical molecules. We propose the arithmetic-geometric Banhatti index and multiplicative arithmetic-geometric Banhatti index of a molecular graph. In this paper, we compute these Banhatti topological indices of certain infinite classes of dendrimer nanostars.

O artigo apresenta os resultados de uma pesquisa sobre as relações étnico-raciais no currículo de uma escola do campo. O objetivo foi identificar de que forma conteúdos de história e cultura afro-brasileira e africana são trabalhados pelos professores das disciplinas de Língua Portuguesa, História, Ciências e Artes da Escola Municipal Margarida Maria Alves, localizada na cidade de Amargosa-Ba. Para a produção dos dados, realizamos uma pesquisa qualitativa, do tipo estudo de caso utilizando a entrevista semiestruturada.  Os dados foram organizados segundo a técnica de análise de conteúdo e permitem apontar que as práticas pedagógicas dos professores apresentam indícios de uma educação intercultural para os estudantes camponeses.
Governance of the right to privacy under administrative and penal legislation: An analytical study
Authors: Alshawabkeh Faisal Abdulhafez , Shiyab Tayil Mahmoud
Published: January 2023

This research is concerned with the administrative and penal protection of the right to privacy under the United Arab Emirates (UAE) legislation, in comparison with the relevant Jordanian legislation. The purpose of this research is to clarify the concept of the right to privacy (Bennett & Raab, 2020), the important forms of violation of this right, its relation with governance (Rajaretnam, 2022), and the legal texts enacted and the amendments adopted in the respective countries in order to notice the strengths and weaknesses of these two laws and indicate opportunities for improvement. The research problem consists of the insufficient legal framework in the UAE and Jordan regarding the content and the means of the protection of this right. It is suggested that this goal is achieved by comparing the different laws adopted in these two countries. The main findings of the paper are that the UAE and Jordanian legislations need to be modified to comply with the new technologies due to the multiplicity of agencies supervising the protection of this right and the absence of a central authority. Finally, the study concludes that legislators in the UAE and Jordan should adopt measures of governance to ensure the effectiveness of the legal framework relating to this right.
Variation in genomic vulnerability to climate change across temperate populations of eelgrass (Zostera marina)
Authors: Jeffery Nicholas , Vercaemer Benedikte , Stanley Ryan , Kess Tony , Wong Melisa
Published: January 2023

A global decline in seagrass populations has led to renewed calls for
their conservation as important providers of biogenic and foraging
habitat, shoreline stabilisation, and carbon storage. Eelgrass (Zostera
marina) occupies the largest geographic range among seagrass species
spanning a commensurately broad spectrum of environmental conditions.
However, relatively little is known about their fine-scale genetic
structure and broad-scale genomic signatures of environmental
adaptation, and in Canada, eelgrass is considered a single phylogroup
despite occurring across three oceans. We used a pooled whole-genome
re-sequencing approach to characterise population structure, gene flow,
and adaptation of 23 eelgrass populations ranging from the Northeast
United States, to Atlantic, subarctic, and Pacific Canada. We identified
over 500,000 SNPs, which when mapped to a chromosome-level genome
assembly revealed six broad clades of eelgrass across the study area,
with pairwise FST ranging from 0 among neighbouring populations to 0.54
between Pacific and Atlantic coasts. Genetic diversity was highest in
the Pacific and lowest in the Arctic, consistent with colonisation of
the Arctic and Atlantic oceans from the Pacific. Using redundancy
analyses and two climate change projection scenarios, we found that
subarctic populations are more vulnerable to climate change through
genomic offset predictions. Conservation planning in Canada should
ensure that representative populations from each identified clade are
included within a national network so that latent genetic diversity is
protected, and gene flow is maintained. Northern populations, in
particular, may require stronger protective measures given their
susceptibility to change climate.

Incorporation of Arebica in Sandzak and its significance in the process of Muslim womens’ education
Authors: Ziljkic Hasna , Skrijelj Redzep
Published: January 2023

Arebica is mentioned in the literature in the context of Aljamiado
literature, considering that Aljamiado literature was written in this script
(a form of Aebica adapted to the phonetic spelling of the Serbian and
Bosnian languages, used mainly by Muslims). Aljamiado literature, as well
as religious and other literature, were printed in Arebica. Thus, in some
schools in Sandzak, even in the last decade of the 20th century, Arebica was
still used. In this paper, it will be demonstrated how the Arebica was
created, how it was used in Sandzak and the role it played in the literacy
of Muslim women in the 20th century, considering their departure from
?secular? schools. The aim of this study is to survey the use of the Arebica
among the Muslim population in Serbia from the perspective of the education
in the 20th century with a special emphasis on the women, but also to recall
the circumstances that contributed to the existence of a special culture of
language and writing which will remain in our region until the end of the
20th century. In addition to the scientific literature, the paper will also
present transcripts based on conversations with interlocutors in the field
(Tutin, Novi Pazar and Pester Municipality).
