Bioactive Food Compounds in Cardiovascular Disease
(Springer, Cham, 2026) Shubhrat Maheshwari, Aditya Singh, Amita Verma, Vaseem A. Ansari, Bhupendra G. Prajapati
Cardiovascular diseases (CVDs) remain a major global health burden, driven by modifiable risk factors such as sedentary behavior, hypertension, obesity, smoking, poor diet, and chronic stress. Among the various preventive strategies, dietary modulation through the intake of plant-food-derived bioactive compounds has garnered substantial attention. Bioactive food compounds (BFCs) such as polyphenols, flavonoids, carotenoids, alkaloids, phytosterols, and omega-3 fatty acids exhibit a range of cardioprotective effects including antioxidant, anti-inflammatory, antihypertensive, lipid-lowering, and antithrombotic actions. This chapter highlights the physiological and molecular mechanisms through which these compounds exert their benefits, such as modulating nitric oxide production, improving endothelial function, inhibiting LDL oxidation, and reducing systemic inflammation.
Bioactive Food Compounds Against Liver Cancer
(Springer, Cham, 2026) Aditya Singh, Shubhrat Maheshwari, Amita Verma, Vaseem A. Ansari, Bhupendra G. Prajapati
Liver cancer arises from the dysregulated proliferation of hepatic cells and is driven by a multitude of contributing factors, as revealed through advanced cellular biology and comprehensive genomic investigations. Tumor initiation and progression in hepatic tissues are frequently attributed to somatic mutations, which may result in similar phenotypic manifestations across different liver cancer subtypes. Over recent decades, a deeper understanding of the genetic and molecular aberrations involved in hepatocarcinogenesis has emerged. This evolving insight holds promise for the development of innovative therapeutic agents capable of modulating multiple molecular targets implicated in liver cancer progression. This chapter explores the pathophysiological mechanisms underpinning liver cancer, outlines traditional treatment modalities, and highlights the therapeutic potential of bioactive phytochemicals. These naturally occurring compounds, present in everyday dietary sources, represent a valuable adjunct or alternative to existing liver cancer therapies, potentially improving outcomes through multi-target engagement and minimal toxicity.
Marine-Based Polysaccharides in Nose-to-Brain Drug Delivery
(Springer, Singapore, 2026) Shubhrat Maheshwari, Aditya Singh, Amita Verma, Vaseem A. Ansari, Juber Akhtar, Bhupendra G. Prajapati
This chapter explores the potential of marine-based polysaccharides in nose-to-brain drug delivery systems, focusing on their applications for treating central nervous system (CNS) disorders. Marine polysaccharides, including alginates, chitosan, and carrageenans, offer unique advantages due to their natural biocompatibility, biodegradability, and ability to form gels with desirable mechanical properties for drug delivery. These polysaccharides exhibit excellent mucoadhesive properties, enhancing the sustained release and absorption of therapeutic agents through the nasal mucosa. They can effectively bypass the blood-brain barrier (BBB) via olfactory and trigeminal nerve pathways, providing a noninvasive alternative to traditional drug delivery methods. The chapter highlights various synthesis strategies for marine polysaccharide-based hydrogels, including chemical crosslinking and physical stimuli-responsive gelation, and discusses their combination with nanoparticles for enhanced drug release and targeting. In vitro and in vivo studies demonstrate the successful application of these systems in nose-to-brain (N2B) drug delivery, with improved drug retention, reduced side effects, and enhanced therapeutic effects. While challenges remain in improving mechanical strength and optimizing drug release profiles, marine polysaccharides offer great promise as drug carriers for CNS treatments. Further research and development are essential to realize their full potential for treating neurological diseases.
The Role of AI-Powered Chatbots in Online Learning and Student Support
(Book Rivers, 2025) Mohd Gufran Barkati, Sadia Shakeel
The use of AI-powered chatbots in online learning and student support has drastically changed the way of students’ engagement with educational resources. These chatbots have become essential tools in modern education because of their interesting features like personalized learning, real-time feedback and assistance. The AI-chatbots help students in tutoring, provide interactive learning experiences, answer their queries. One of the greatest advantages of these AI chatbots is their 24/7 availability which improves accessibility, cuts response times, and improves overall student satisfaction. Additionally, AI chatbots can assess students’ learning patterns and provide them with tailored recommendations. Regardless of their benefits, these chatbots also present several challenges such as concerns over data privacy, ethical considerations, and problems in managing complex queries. This article explores the role of AI-driven chatbots in online learning and student support, analyse their potential advantages, limitations, and suggests ethical considerations for their implementation in educational settings.
Skill of Using Audio -Visual Aids
(Swarnrudra Publication, 2026) Smita Srivastava
These days, teaching is more than just reading from a textbook. Bringing concepts to life so that students can actually see, hear, and feel them is the goal. In order to make lectures stick, audio-visual (AV) aids are revolutionary.
In order to promote engagement, clarity, and true retention in your classroom, we'll go into a useful, instructor-friendly approach in this chapter on how to use tools like charts, films, models, and digital media. We'll connect all of this to learning theories that explain why children learn concepts more quickly and retain them longer when they use many senses.
In addition, you will learn the fundamentals of this skill, how to develop it through instruction and practical experience, real-world classroom anecdotes, and simple techniques to increase your self-assurance. Lastly, we'll examine why mastering AV aids is essential in our digital world and how it fits perfectly with NEP 2020's vision for vibrant, modern education.
