Stem cells hold great promise for tissue regeneration and have the potential to treat many incurable degenerative diseases. Cancer stem cells (CSCs), or cancer initiating cells, have the ability to self-renew and differentiate into heterogeneous lineages of cancer cells. Current stem cell therapies face limitations, such as limited stem cell sources, time consumption, tumor formation, and immune rejection upon allogeneic transplantation. Allogeneic stem cell treatments simplify stem cell manufacturing and reduce transplant time, but their therapeutic potential is limited by human leukocyte antigen (HLA)-matched donors. CSCs retain characteristics essential for tissue regeneration. However, several limitations hinder cancer stem cell reprogramming with pluripotent factors. The development of 3D culture models for tissue imitating extracellular matrix in cancer cell lines aims to enhance CSC enrichment. This mini-review focuses on a new strategy for treating incurable degenerative diseases involving in vitro and in vivo 3D cancer models and the induced differentiation of CSCs into mature normal cell types. This allows tissue survival without immune rejection and offers a safe alternative to cancer stem cell reprogramming with pluripotent factors. In conclusion, preservation and banking of allogeneic CSCs offer an alternative, readily available, and safe strategy that can be used to facilitate stem cell-based cell therapy.
The motto behind the keenness of urban areas has become unmistakable in current cities because of the rise of installed and associated shrewd gadgets, frameworks, and innovations. It is possible to connect every object to the Internet. As a result, in the impending Internet of Things era, the “Internet of Vehicles-IoV” will play a critical role in newly developed dazzling urban communities. The IoV can possibly address different traffic and street wellbeing issues successfully to forestall deadly crashes. In any case, a specific test of IoV, particularly in “Vehicle-to-Vehicle” as well as “Vehicle-to-Infrastructure” communications, guarantees quick, in order to transmit securely and exact performance of the information. The above effort is modifying Blockchain innovation for continuous application called RTA to meet “Vehicle-to-Every thing-V2x” communications problems in order to overcome these challenges. As a result, the main goal of the study is to develop a Blockchain-based IoT framework for establishing communication security and creating a completely decentralized computing platform. Research methodology used here is divided into two major sections. In the part 1 presented below, authors discuss the traceability and optimization over Merkle trees. The second section deals with implementing an actual blockchain with our optimized Merkle tree as the underlying technology to represent a distributed trust based ledger.
This proposed work is used to optimize the costs of exceptional elements of machine cells for a variety of components in changing environments to have reduced material movements in cell layout. The exceptional ele¬ments are eliminated in the optimization model by doing machine duplication and part subcontract. Then the shop floor layout is designed to have optimized material movements between cells and within a cell. The result of a linear programming optimization model is cost savings, machines duplicated, parts subcon¬tracted, inter intracellular movements. Finally, the output of the inbound facility design is the floor layout which has machine cell clusters with optimized floor areas. The optimization model is provided with budg¬etary constraints for duplication and the economic tradeoff between machine duplication and part subcontract. Cell layout is prepared to reveal the saving in floor area and material movement lengths than in process layout with the help of distance matrix and dimensions of cells.

Methods: The chloroform extract of Glinus lotodies linn was allowed for screening hepatoprotective activity on Paracetamol induced Albino rats and they were compared with standard and negative control. Results: The drug treatment Chloroform Extract of Glinus lotodies linn [CEGL] was carried out at two low dose levels 200mg and 400mg/ kg, both of which along the standard Silymarin 100mg/kg treated group showed a significant reduction in the elevated enzyme levels (P < 0.01). Liver section shows normal cells compared to control. Conclusion: These data suggests a dose dependent hepatoprotective activity of CEGL. At the end of this study, a strong conclusion can be drawn that the Chloroform Extract of Glinus lotoides linn possess hepatoprotective activities induced by Paracetamol in Albino rats.
Background: E-waste, is the waste generated from used electrical and electronic devices that are no longer fit for their original intended use. Currently e-waste comprises more than 5% of total municipal waste flow, equivalent to 20-50 million tonnes annually worldwide. In 2014, Nigeria generated about 219 kilo tonnes of e-waste. The study aimed to increase public awareness on the need for proper management of e-waste because of its hazardous nature. Methods: This was a cross-sectional study in Enugu West Senatorial District of Enugu State comprising Oji-River, Ezeagu, Udi, Awgu and Aninri Local Government Areas with a population of 980,988. An adaptation of the UNEP, EMPA and Basel convention questionnaire, administered to 400 households was used for data collection. Results: The potential e-waste generation in the study area was 0.05 kg per inhabitant. 76% of the households were aware of the hazards of e-waste. 64% were willing to give out their e-waste to waste collectors. Only 26% of the e-waste were collected with the general waste. The correlation between awareness of the hazards of e-waste and willingness of the households to give out their e-waste was positive, moderate, and insignificant (r= 0.43, p=0.47). Conclusions: Although 76 per cent of the households were aware of the hazards of e-waste, with 64% willing to give out their e-waste, only 26% of the e-waste were eventually collected together with the general waste. There is a need to create a separate e-waste collection system.
This case is designed to highlight the marketing strategies adopted by a new entrant in the fast-moving consumer goods (FMCG) sector. The importance of brand architecture in building brand relevance in this competitive environment and enhancing customer loyalty has been put forth as illustrated by the experts. The synchronization of branding strategies and marketing communications in terms of establishing a customer connect purely on the basis of nationalism, price, and natural preparations have been highlighted from the perspective of Patanjali’s growth strategy. The brand has been envied by all the big players of the sector for proving itself as the major disruptor being portrayed in terms of its voluminous sales and ever-rising revenues. This case on Patanjali offers an insight into the strategies followed by a new company to position the brand at the right time and acquire a substantial market share. It also highlights the facts that exceptional competitiveness in distribution strategies may not be the only determinant for effective management of distribution strategies, and the road ahead needs to be rightly sorted out. This case also tries to unlock the path that determines the success the brand Patanjali has achieved which otherwise took decades for Nestle, Proctor & Gamble, ITC, or Unilever to achieve.
Plants produce a diverse range of bioactive compounds making them a rich source of different types of medicines. Ornamental plants are cultivated for adornment and to enhance the appearance of houses and also for commercial purposes. However, only very few of these ornamental plant species have found to be used in medicine and only little literature exit on their chemical and biological actions. In the present study, the evaluation of antimicrobial activities and identification of bioactive compounds using TLC and GC-MS of the A. columnaris bark extract were performed. In GC-MS bioactive compounds with medicinal value were identified, such as Benzoic acid, 1H-N-Hydroxynaphth (2,3) imidazole-6,7-dicarboximide, 2-Propenoic acid, 3-(4-methoxyphenyl), 1H-N-Hydroxynaphth (2,3-d) imidazole-6,7-dicarboximi. To prove the nontoxic nature of the plant, its crude bark extract was subjected to toxicity study using human embryonic kidney cell line. It reveal that the plant is minimal toxic to the human kidney cell line so usage of appropriate level will found to be safe and also carrying out some structural modification will help in the extraction of new drugs for pharmaceutical purpose.
The COVID-19 was announced as pandemic by WHO on March 11th, 2020. Five days later, on March 16th, 2020 prevention measures to prevent the outbreaks had been taken by authorities in Libya. The health care institutes were working during the quarantine and until now. Pharmacists as health care professionals have a critical role in COVID-19 pandemic. This study aimed to access the levels of knowledge, attitude and practice (KAP) of community pharmacists, hospital pharmacists and pharmacy assistants toward COVID-19 in Libya. A cross-sectional online survey was conducted in period from November, 2020 to January, 2021. Data was analyzed using descriptive statistics and Chi-square to measure the differences and association within socio-demographic variables. Pearson correlation was used to measure the relationship between KAP of pharmacists. A total of 205 responses were received. The majority of respondents were from the eastern part of Libya. The percent of good knowledge score was 61.5%, the percent of adequate attitude score was 59% and the percent of sufficient practice score was 56.6%. There was an association between knowledge score and respondent’s professional and educational level with P=0.008 and P=0.028, respectively. There was an association between score of attitudes and working setup, professional level and educational level with p = 0.003, 0.011 and 0.002, respectively. There was also an association between practice score with regard to gender, age educational level and work place with P=0.004, P=0.017, P=0.002 and P=0.027, respectively. There was a positive relationship between knowledge and attitude (P>0.05). In conclusion, the KAP of community pharmacists, hospital pharmacists and pharmacy assistants were low but acceptable. Therefore, KAP should be improved among pharmacists by implanting an effective health education programs in Libya.

Social Network sites are one of the most prominent websites used in almost every facet of life. A social network reflects relationships among social entities, including acquaintances, co-workers, or co-authors. With the extreme success of Social networks, the misuse has also been escalated and unlocked the way for various illegal behavior and security threats. Social Network anomaly detection has become a critical topic to be explored by researchers. The nature of the input data is a significant aspect of an anomaly detection technique. In the field of anomaly detection in the social network, input networks can be classified as static or dynamic, Attributed or unattributed. The number of nodes and the connections between the nodes in static networks would not change with time. Attribute networks are pervasive in various domains and constitute a vital element of modern technological architecture, where node attributes support the topological structure in data exploration. While social networks build up over time, evaluating them as if they had been static is very beneficial. Numerous studies have been done for Anomaly detection, but to the best of our knowledge, research in static attributed anomaly detection has been very limited. This review tries to portray earlier research on detecting anomalies for social static attributed networks and thoroughly discusses state-of-the-art embedding approaches
The quality of software systems may be seriously impacted by specific types of source code anomalies. For example, poor programming practices result in Code Smells (CSs), which are a specific type of source code anomalies. They lead to architectural problems that consequently impact some significant software quality attributes, such as maintainability, portability, and reuse. To reduce the risk of introducing CSs and alleviate their consequences, the knowledge and skills of developers and architects is essential. On the other hand, ontologies, which are an artificial intelligence technique, have been used as a solution to deal with different software engineering challenges. Hence, the aim of this paper is to describe an ontological approach to representing and analyzing code smells. Since ontologies are a formal language based on description logics, this approach may contribute to formally analyzing the information about code smells, for example, to detect inconsistencies or infer new knowledge with the support of a reasoner. In addition, this proposal may support the training of software developers by providing the most relevant information on code smells. This ontology can also be a means of representing the knowledge on CSs from different sources (documents in natural language, relational databases, HTML documents, etc.). Therefore, it could be a valuable knowledge base to support the struggle of software developers and architects either to avoid CSs or to detect and remove them. The ontology was developed following a sound methodology. The well-known tool Protégé was used to manage the ontology and it was validated by using different techniques. An experiment was conducted to demonstrate the applicability of the ontology and evaluate its impact on speeding up the analysis of CSs.
Objective: To explore unusual association between Turner Syndrome (TS) and Hypopituitarism in a Tunisian cohort. Methods: We reported 6 patients with TS associated to Hypopituitarism, including three familial cases except the fourth sister who showed only a TS phenotype. Biochemical analysis, resonance magnetic imaging and cytogenetic analyses were performed. Results: The average age of our patients was 17.2 years (11-31 years). They were all referred for short stature and pubertal delay, except for the fourth sister who presented spontaneous puberty with the integrity of the pituitary axis and the presence of an X ring chromosome. Karyotype analysis showed monosomy in 3 cases and a mosaic TS in the 3 remaining cases, including one patient with abnormal X chromosome structure. Somatotropic and corticotropic deficiencies were confirmed in 2 sporadic cases while the gonadotropic and thyrotropic axes were spared. In contrast; familial cases were consistently affected by the integrity of the corticotropic axis. MRI showed pituitary hypoplasia in all familial cases and pituitary stalk interruption syndrome in only one sporadic case. No correlation was found between the chromosome formula and the anterior pituitary involvement. Conclusion: Co-segregation of congenital Hypopituitarism with pituitary hypoplasia and X chromosome aberrations could imply a molecular anomaly of transcription factors responsible for the differentiation and development of pituitary cells such as PROP1, POUF1, Hesx1, Lhx3, Lhx4. The etiopathogenic link between X chromosome abnormalities and the occurrence of Hypopituitarism remains unclear; however, the progress of molecular biology may clarify the interrelation between transcription factors and sex chromosome segregation abnormalities.
Étudier les phénomènes grammaticaux actuels sans s’interroger sur la longue trajectoire historique qui a servi de support et de canal au français moderne manquerait de pertinence. En effet, une telle étude permet une meilleure compréhension des phénomènes linguistiques contemporains. Ainsi, notre domaine de recherche, la linguistique diachronique, met l’accent sur les connaissances étymologiques de la langue. Il s’agira, pour les besoins de l’article, de rendre compte de l’évolution morphologique du présent de l’indicatif depuis le latin jusqu’au français moderne. Notre curiosité nous poussera à nous interroger sur les raisons qui expliquent l’écart morphologique du présent de l’indicatif entre le latin et le français moderne. En sus, l’étude des variations diachroniques du présent de l’indicatif renseigne sur les formes actuelles de ce temps verbal. Du latin au français moderne, le présent de l’indicatif subit des flottements aussi bien dans ses radicaux que dans ses désinences. Ceci met en chef l’écart formel existant entre le présent latin et celui du français actuel. Toutefois, les phonèmes subirent des transformations selon qu’ils étaient toniques ou atones, radicaux ou désinentiels. Certaines formes se sont maintenues avec modification ou non de sons; d’autres ont complètement disparues du système. Suivant un ordre chronologique et des lois phonétiques cohérentes, nous montrerons que les formes actuelles du temps le plus usuel du système, le présent, ne sont pas le fruit du hasard. De ce fait, la langue moderne gagnerait à revisiter la morphologie des temps verbaux depuis leur origine pour mieux asseoir les difficultés liées à la conjugaison et fournir une explication authentique sur les variations de forme jusque-là ignorées par certains.

The use of performance feedback in the workplace has gained popularity over the years, yet school heads have been challenged in providing it to teachers. In the initial interview, they shared that evaluation results can impact teachers’ motivation, and that feedback should be done carefully. However, they failed to clearly articulate a specific mechanism that had been applied in this vital role. Also, no studies have provided clear detail on the feedback mechanism used by school heads in the past. For this reason, a study explored the feedback mechanisms employed by school heads in conveying the performance evaluation results to teachers. This study employed a narrative inquiry, and interviews were conducted with five school heads and five teachers who were chosen purposively for this research. Responses were recorded using a voice recorder. These responses were transcribed and analyzed using thematic narrative analysis. Based on transcripts, the study identified six emergent themes, such as conversational (one-on-one), relational, reflective, technical, reinforcing, and properly situated mechanisms in conveying performance evaluation results to teachers. Thus, a new feedback mechanism framework was developed.
The aim of this study was to evaluate the knowledge, attitude, and practice of pharmacovigilance by healthcare professionals in Benghazi. A structured questionnaire adapted from a previous validated study. One hundred questionnaires were distributed in August 2019 and filled by healthcare providers working at different hospitals in Benghazi, Libya. Participants were 57% physicians and 43% pharmacists (age average 31-40 years). 47% had correctly defined Pharmacovigilance while 19% know what is meant by adverse drug reactions. Moreover, 61% of the participants did not share information about raising adverse drug reactions in some patients with other healthcare professionals. 35% of them did not know about the adverse drug reactions reporting system in Libya. Whereas, 42% have strongly agreed that reporting adverse drug reactions is essential. 41% and 45% of participants believed that reporting adverse drug reactions is not time-consuming and increases patient safety, respectively. In conclusion, educational programs and training courses about the importance of Pharmacovigilance for physicians and pharmacists in Benghazi are needed.

ABSTRACT- Objective- The principal objective of the present investigation was the preparation of several analogs to further evaluate the binding site hypothesis. Aryl semicarbazides have also been reported to display excellent anticonvulsant activity in mice and rats. Method- In this project, the synthesis of semicarbazone derivatives was carried out. All molecules were synthesized using the common starting material –aniline. In all compounds, an intermediate was first formed by substituted phenyl urea using substituted aniline and potassium cyanate, and then it was hydrolyzed to get substituted phenyl semicarbazide, which was directly coupled with ketones. All the synthesized compounds were biologically screened for their anticonvulsant activity by the MES method. Result- Standard error mean was calculated concerning standard and control drug, Phenytoin sodium (25mg/kg.) and DMSO. The synthesized semicarbazone was characterized by using IR Spectroscopy. One another representative molecule compound was characterized using 1H NMR Spectroscopy. Conclusion- It can be concluded that designed semicarbazones were synthesized and characterized successfully. After synthesis of designed semicarbazones compounds were evaluated for anticonvulsant activity. Finally, two compounds have shown better activity in comparison to the other molecules.
Higher education is leadership education. The values and virtues practiced in universities heavily influence the future leaders. Many institutions of higher education simultaneously show excellence in academic subjects, are green campuses with manifold ethics curricula, are active members in community engagement, and also are adept in providing value orientation to all stakeholders. It is universally felt that the status of teaching profession requires to be raised to ensure its dignity and integrity. Accordingly, it is considered necessary that there should be a code of ethics which may be evolved by the teaching community itself for its guidance. There are five major areas of professional activities which encompass the work of a teacher. For each of these areas certain principles have been identified to serve as guidelines for teacher’s conduct. HUMAN VALUES Basic human values refer to those values which are at the core of being human. The values which are considered basic inherent values in humans include truth, honesty, loyalty, love, peace, etc. because they bring out the fundamental goodness of human beings and society at large.

Efforts to understand the causes of poverty, how poverty is perceived have become important in the fight to mitigate poverty. In Vietnam, studies on the attitudes of poverty in specific populations, such as Vietnamese students, are rare. Thus, this dataset reports the results collected from 180 social work students and non-social work students of Ho Chi Minh City Open University through attitudes toward poverty and poor people in Vietnam. The Attitude toward Poverty Short Form 21-item scale, developed by Yun & Weaver, was used for the data collection. The survey results showed that when looking for causes of poverty, social work students and non-social work students put the most emphasis on structural factors of poverty. However, social work students, compared with non-social work students, consider personal deficiency and stigma more important. In future, this dataset can serve as a reference source for comparative studies on student’ attitudes toward poverty and impoverished persons and for social work education
