Abstract

In this article, the author invokes Cummins’ model for social empowerment of minority students to suggest an alternative way of thinking about the empowerment of school communities. This paper explains Cummins’ theoretical framework and suggests implications that might help teachers better understand social language literacy development in terms of Cummins’ (1986-1994) conceptual framework, which is based on the notion that students who are from a diverse background are in need of school literacy learning that attends to “the goals of instruction, the role of the home language, instructional materials, classroom management and interaction with students, relationships with the community, instructional methods and assessment” (Au, 1998, p. 298). This paper also attempts to explain how the relationships among students’ literacy development, social practices, and their diverse background empower them and assess them in developing their learning literacy skills, taking into consideration the types of literacy that best work with diverse communities.

Abstract

Abstract Follicular dendritic cell sarcoma (FDCS) is a rare malignancy, often challenging to diagnose due to its nonspecific presentation and resemblance to other neoplasms. This case highlights a locally advanced nasopharyngeal FDCS initially misdiagnosed as a meningioma, underscoring the importance of differential diagnosis in unusual tumor presentations. A 77-year-old patient presented with nasal obstruction for 3 months. Imaging studies revealed a mass in the nasopharynx prolapsing into the oropharynx, leading to an initial diagnosis of meningioma based on its radiologic appearance. Surgical resection was performed, and histopathological examination, supplemented by immunohistochmical staining, revealed features consistent with follicular dendritic cell sarcoma. The tumor was locally advanced, involving surrounding structures, which complicated the initial clinical and radiologic assessment.

Abstract

Laurus nobilis, commonly known as bay, is used in folk medicine as a remedy for many ailments. The present study investigates the protective effect of L. nobilis leaves extract against high fat diet-induced type 2 diabetes in rats. Animals were divided into group 1 (control), groups 2, 3, and 4 (bay leaves aqueous (AQ) extracts; 50, 100, and 250 mg/kg of body weight, respectively), and groups 5, 6, and 7 (bay leaves methanol/acetone (MeAc) extract; 50, 100, and 250 mg/kg of body weight, respectively). Animals were fed an isocaloric high fat diet for four weeks. The intake of bay leaves extracts was associated with a significant decreases in serum levels of glucose (AQ, 100 and 250 mg/kg; MeAc, 50, 100, and 250 mg/kg) and serum triglyceride (AQ, 250 mg/kg; MeAc, 100, and 250 mg/kg) as well as lower abdominal fat (all AQ and MeAc groups) and body weight gain (MeAc groups only). In conclusion, L. nobilis leaves extract intake provides a protective remedy against high fat diet-induced type 2 diabetes. Key words: Laurus nobilis, type 2 diabetes, bay leaves, high fat diet.

Abstract

In a smart city environment, various intelligent devices, applications, and digital networks collaborate to provide technological solutions for the public good. The exponential data generated from intelligent interactions among stakeholders within the smart city ecosystem raises concerns regarding security and privacy. Maintaining data openness while safeguarding it against social engineering attacks, network breaches, and data masking threats is paramount to achieving resilience. Blockchain technology has demonstrated great promise in addressing these challenges due to its decentralized, consistent, and tamper-proof nature. Our paper explores how blockchain can address the challenges of integrity, security, and privacy in smart city operations. Despite significant research efforts, the subject remains in need of a comprehensive survey. Consequently, we conduct a study on state-of-the-art blockchain-based reputation and trust management methods within the three fundamental components of a smart city: energy, healthcare, and transportation. The trust and reputation mechanisms are analyzed to identify their strengths and limitations. The investigation reveals that the existing trust schemes are resource-constrained and encounter scalability limitations, high energy consumption, and incompatibility with existing systems.

Abstract

The relationship between academia and industry is old. However, a twist is necessary to move from the traditional exchange of funding for research to the creation of long-term strategic partnerships of mutual benefit. The purpose of this study is to explore the effort made in Lebanon to forge the industry-academia link and to highlight the challenges faced. The researcher relied on both secondary and primary data. A review of the literature is made to set the theoretical framework regarding the need for creating strategic partnerships between academia and industry and its impact on sustainable economic growth. The researcher distinguished strategic partnership from the conventional exchange of research for funding approach. Moreover, she described the lessons learned from international experiences. Primary data are collected about Lebanon through interviewing key actors both in the industry and in academia. The study revealed that Lebanon realized several years ago the need to link academia to industry, several actors took measures to facilitate the collaboration. However, some measures did not reach their full potential yet due to some challenges. The author suggests few recommendations to overcome these challenges and strengthen the academia-industry collaboration.

Abstract

Transformer architectures are highly expressive because they use self-attention mechanisms to encode long-range dependencies in the input sequences. In this paper, we present a literature review on Transformer-based (TB) models, providing a detailed overview of each model in comparison to the Transformer’s standard architecture. This survey focuses on TB models used in the field of Natural Language Processing (NLP) for textual-based tasks. We begin with an overview of the fundamental concepts at the heart of the success of these models. Then, we classify them based on their architecture and training mode. We compare the advantages and disadvantages of popular techniques in terms of architectural design and experimental value. Finally, we discuss open research, directions, and potential future work to help solve current TB application challenges in NLP.

Abstract

This paper demonstrates, for the first time, the stability of synthetic diamond as a passive layer within neural implants. Leveraging the exceptional biocompatibility of intrinsic nanocrystalline diamond, a comprehensive review of material aging analysis in the context of in-vivo implants is provided. This work is based on electric impedance monitoring through the formulation of an analytical model that scrutinizes essential parameters such as the deposited metal resistivity, insulation between conductors, changes in electrode geometry, and leakage currents. The evolution of these parameters takes place over an equivalent period of approximately 10 years. The analytical model, focusing on a fractional capacitor, provides nuanced insights into the surface conductivity variation. A comparative study is performed between a classical polymer material (SU8) and synthetic diamond. Samples subjected to dynamic impedance analysis reveal distinctive patterns over time, characterized by their physical degradation. The results highlight the very high stability of diamond, suggesting promise for the electrode’s enduring viability. To support this analysis, microscopic and optical measurements conclude the paper and confirm the high stability of diamond and its strong potential as a material for neural implants with long-life use.

Abstract

As cancer treatment improves, more young women of reproductive age are surviving, but they suffer from infertility as a consequence of the radiation and chemotherapy. Human ovarian tissue containing immature primordial follicles has been successfully cryopreserved. The ultimate aim of this technique is to induce ovarian function by re-plantation of ovarian tissue or, further into the future, by in vitro maturation (IVM) of the oocytes derived from the cryopreservedthawed ovarian tissue, followed by routine in vitro fertilization. IVM of primordial follicles from young cancer survivors would avoid the risk of cancer retransmission by the ovarian grafts. The present review discusses the current achievements in IVM of female germ cells and primordial ovarian follicles and the attempts to improve their development by adding various factors to the culture medium. The established methods for the evaluation of survival and growth in culture are also discussed: follicular counts, immunocytochemical methods, transmission electron microscopy, fluorescent viability markers and endocrine assays. Although the development of IVM systems is still in its infancy, researchers need to pursue their approach step-by-step, especially with regard to factors that might be involved in the activation of the ovarian follicles or female germ cells. The final measure of success will be the ability of the in vitro matured oocytes to fertilize and produce healthy offsprings. The availability of such treatment will probably lead to its demand not only by cancer patients but by other women as well.

Abstract

Abstract Collision tumors associating carcinoid tumor and sclerosing pneumocytoma have rarely been reported in the literature. The clinical presentation may be challenging especially in cases showing multiple and bilateral nodules. This case illustrates the association of both tumors diagnosed incidentally and illustrates a full spectrum of neuroendocrine lesions and sclerosing pneumocytoma. The authors present the case of a 52‐year‐old patient presenting an abdominal pain revealing a vesicular lithiasis and multiple pulmonary nodules. Radiologic follow‐up of the asymptomatic lung lesions revealed the stabilization of a left lobe lesion with a disappearance of the other lesions. A lobectomy with a mediastinal lymph node curettage was performed. The microscopic examination revealed both tumor components associating a typical carcinoid tumor to a sclerosing pneumocytoma in association to lesions of diffuse neuroendocrine hyperplasia present in the peri‐tumoral parenchyma. This case illustrates radiologic, gross, and microscopic features of a rare pulmonary tumor.

Abstract

Background The use of marijuana (MJ), combustible cigarettes (hereafter cigarettes), and electronic nicotine delivery systems (ENDS) is widespread among United States (US) adults and linked to worsening respiratory symptoms, especially among adults with asthma. This study examined state-specific prevalence and factors associated with MJ, ENDS, and cigarette use among US adults with asthma. Methods We analyzed data of 41 974 adults aged ≥18 years having self-reported current asthma from the 2018 Behavioral Risk Factor Surveillance System (BRFSS). We reported weighted prevalence to account for complex survey design and performed multivariable logistic regression models to examine factors associated with current use of MJ, ENDS, and cigarettes. Results Overall prevalence of current MJ, ENDS, and cigarette use among adults with asthma was 14.5%, 6.6%, and 27.2%, respectively. Our results showed the US states and territories with highest and lowest use prevalence for MJ (California: 23.6% vs Guam: 3.2%), ENDS (Indiana: 12.8% vs North Dakota: 4.0%), and cigarettes (West Virginia: 42.1% vs Guam: 12.3%). Both MJ and ENDS users were more likely to be male, younger, and live in an urban area, but MJ users were more likely and ENDS users less likely to be Non-Hispanic (NH) American Indian/Alaskan Native. Cigarette users were more likely to be older, have at least 1 health condition, and were less likely to be NH Black or Hispanic and college-educated. Conclusion Many US adults with asthma use MJ, ENDS, and cigarettes. Our findings provide insights for clinicians about the urgent need for effective interventions to reduce tobacco and MJ use among adults with asthma.

Abstract

To aim of the study was to investigate whether controlled ovarian hyperstimulation (COH) causes endothelial activation and whether there is a correlation between endothelial activation and serum sex-steroid levels.The study population consisted of 14 consecutive patients undergoing our routine IVF long gonadotropin-releasing hormone-analog protocol. Blood was drawn three times during the COH cycle: (1) day when adequate suppression was obtained (Day-S); (2) on the day of or the day prior to hCG administration (Day-hCG); and (3) on the day of ovum pick-up (Day-OPU). The levels of sex steroids and plasma soluble endothelial (E)-selectin were compared among the time points. Soluble E-selectin was measured with a commercial sandwich enzyme-linked immunosorbent assay.Soluble E-selectin levels were significantly higher on Day-OPU than Day-S and Day-hCG, whereas no difference was observed between Day-hCG and Day-S. No significant correlations were found between soluble E-selectin level and patient age, number of gonadotropin ampoules used, number of oocytes retrieved, or serum estradiol, progesterone and human chorionic gonadotropin levels.Human chorionic gonadotropin administration leads to endothelial activation regardless of the degree of ovarian response. Further studies are required to elucidate the relationship between COH and endothelial activation. These findings may lead to new strategies for predicting and preventing complications of COH, such as severe ovarian hyperstimulation syndrome.

Abstract

To proactively mitigate malware threats, cybersecurity tools, such as anti-virus and anti-malware software, as well as firewalls, require frequent updates and proactive implementation. However, processing the vast amounts of dataset examples can be overwhelming when relying solely on traditional methods. In cybersecurity workflows, recent advances in natural language processing (NLP) models can aid in proactively detecting various threats. In this paper, we present a novel approach for representing the relevance and significance of the Malware/Goodware (MG) datasets, through the use of a pre-trained language model called MalBERTv2. Our model is trained on publicly available datasets, with a focus on the source code of the apps by extracting the top-ranked files that present the most relevant information. These files are then passed through a pre-tokenization feature generator, and the resulting keywords are used to train the tokenizer from scratch. Finally, we apply a classifier using bidirectional encoder representations from transformers (BERT) as a layer within the model pipeline. The performance of our model is evaluated on different datasets, achieving a weighted f1 score ranging from 82% to 99%. Our results demonstrate the effectiveness of our approach for proactively detecting malware threats using NLP techniques.

Abstract

Sera from diabetic patients or sera with high levels of diabetic metabolic products, were found to affect mouse and rat blastocysts. In the present study we examined the earliest developmental stages at which human diabetic serum will be lethal to mouse pre-implantation embryos, and whether reactive oxygen species (ROS) are involved in these diabetes-induced injuries. We cultured 2-4 cell-stage embryos and blastocysts in a medium containing 30 or 50% serum obtained from pregnant women with diabetes Type I, Type II and gestational diabetes (GDM) for 72 h. The development of the 2-4 cell-stage embryos was delayed when cultured in 30% diabetic serum, but the viability was impaired to a lesser extent. Viability was reduced in blastocysts cultured in 50% diabetic serum, but the development of the living embryos was not delayed. Cyclic voltametry measures the oxidation potential of the tissue and the concentration of antioxidants, thus reflecting the total antioxidative activity of the embryos. Pre-implantation embryos cultured in diabetic serum had a lower concentration of antioxidants than embryos cultured in non-diabetic serum. It seems, therefore, that diabetic metabolic factors may induce embryotoxicity in pre-implantation embryos through derangement of the antioxidant defense mechanism. A similar mechanism is suggested for the diabetes-induced teratogenicity in post-implantation embryos.

Abstract

Schinus molle (SM) was investigated as a primary source of cellulose with the aim of discovering resources to generate cellulose nanofibers (CNF). The SM was put through a soda pulping process to purify the cellulose, and then, the fiber was treated with an enzymatic treatment. Then, a twin-screw extruder and/or masuko were utilized to help with fiber delamination during the nanofibrillation process. After the enzymatic treatment, the twin-screw extruder and masuko treatment give a yield of 49.6 and 50.2%, respectively. The optical and atomic force microscopy, morfi, and polymerization degrees of prepared cellulosic materials were established. The pulp fibers, collected following each treatment stage, demonstrated that fiber characteristics such as length and crystallinity varied according to the used treatment (mechanical or enzymatic treatment). Obviously, the enzymic treatment resulted in shorter fibers and an increased degree of polymerization. However, the CNF obtained after enzymatic and extrusion treatment was achieved, and it gave 19 nm as the arithmetic width and a Young’s modulus of 8.63 GPa.
