In silico molecular docking study of Andrographis paniculata phytochemicals against TNF-? as a potent anti-rheumatoid drug
Tumor necrosis factor-? (TNF-?) is a proinflammatory cytokine which plays a crucial role in controlling inflammatory responses. The pathway of Rheumatoid arthritis (RA) leading to TNF-alpha is activated by macrophages and quite often by natural killer cells and lymphocytes. In the inflammatory phase, it is believed to be the main mediator and to be anchored with the progression of different diseases such as ankylosing spondylitis, Crohn's disease, and Rheumatoid arthritis (RA). The major goal of this study is to use in silico docking studies to investigate the anti-inflammatory potential of a bioactive molecule from the medicinal plant Andrographis paniculata. The three-dimensional structures of different phytochemicals of A. paniculata were obtained from PubChem database, and the receptor protein was derived from PDB database. Docking analysis was executed using AutoDock vina, and the binding energies were compared. Bisandrographolide A and Andrographidine C revealed the highest score of ?8.6 Kcal/mol, followed by, Neoandrographolide (?8.5 Kcal/mol). ADME and toxicity parameters were evaluated for these high scoring ligands and results showed that Andrographidine C could be a potent drug, whereas Neoandrographolide and Bisandrographolide A can be modified in invitro and can lead to a promising drug. Further, the top scorer (Andrographidine C) and control drug (Leflunomide) were subjected to 100 ns MD Simulation. The protein complex with Andrographidine C had more stable confirmation with lower RMSD (0.28 nm) and higher binding energy (?133.927 +/? 13.866 kJ/mol). In conclusion, Andrographidine C may be a potent surrogate to the disease-modifying anti-rheumatic drugs (DMARDs) & Non-steroidal anti-inflammatory drugs (NSAIDs) that has fewer or minor adverse effects and can aid in RA management. 2022 Informa UK Limited, trading as Taylor & Francis Group. -

Detection and Classification of Colorectal Polyp Using Deep Learning
Colorectal Cancer (CRC) is the third most dangerous cancer in the world and also increasing day by day. So, timely and accurate diagnosis is required to save the life of patients. Cancer grows from polyps which can be either cancerous or noncancerous. So, if the cancerous polyps are detected accurately and removed on time, then the dangerous consequences of cancer can be reduced to a large extent. The colonoscopy is used to detect the presence of colorectal polyps. However, manual examinations performed by experts are prone to various errors. Therefore, some researchers have utilized machine and deep learning-based models to automate the diagnosis process. However, existing models suffer from overfitting and gradient vanishing problems. To overcome these problems, a convolutional neural network- (CNN-) based deep learning model is proposed. Initially, guided image filter and dynamic histogram equalization approaches are used to filter and enhance the colonoscopy images. Thereafter, Single Shot MultiBox Detector (SSD) is used to efficiently detect and classify colorectal polyps from colonoscopy images. Finally, fully connected layers with dropouts are used to classify the polyp classes. Extensive experimental results on benchmark dataset show that the proposed model achieves significantly better results than the competitive models. The proposed model can detect and classify colorectal polyps from the colonoscopy images with 92% accuracy. 2022 Sushama Tanwar et al. -
Computer-based Intelligence and Security
There is a massive increase in the incidence of cyberattacks day by day in the modern enterprise environment. Although humans are behind this task due to the rapid growth in the incidence human intervention is unable to control this. Therefore, something more than human intervention is required to have a check over it. With cyberattacks evolving at a rapid pace and with the increase in the use of devices in todays world, Artificial Intelligence (AI) and Machine Learning (ML) can help to have a check over cybercrime incidences, automate the process of detection of threat, and handle these in a better way as compared to the conventional methods used for controlling cybercrime and cyberattack. AI and ML has shown good results in data information security as these technologies are capable of analyzing a large and wide variety of data and can track threats related to cyberattacks that may cause phishing attacks. As these technologies are capable of learning and improving from past experiences, they can even predict and tell the new variety of attacks that may occur in the coming days. This chapter describes the use of AI in controlling cyberattacks and cybercrime and the expert views on this matter. 2024 selection and editorial matter, S. Vijayalakshmi, P.

Detection of colorectal cancer using dilated convolutional network via Raman spectra
Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide. Early detection plays a crucial role in improving patient outcomes and reducing mortality rates. In recent years, Raman spectroscopy has emerged as a promising tool for non-invasive cancer detection. This research introduces a new method for identifying colorectal cancer (CRC). It combines Raman spectroscopy, a technique that analyzes the molecular fingerprint of tissues, with a powerful deep learning algorithm called a dilated convolutional network (DCN). By combining these two tools, the researchers aim to improve the accuracy and reliability of diagnosing CRC. Intraoperative diagnostics and pathology need to distinguish tumors from normal tissues. This proposal explores Raman spectroscopy as a new surgical tool for identifying colorectal cancer during surgery. Raman spectroscopy offers a way to directly analyze the makeup of tissue, potentially revealing the presence of cancer. However, surrounding tissue can create background interference, making it difficult to detect the key signal. The authors suggest that high-quality data from Raman spectroscopy combined with advanced deep learning algorithms could be a solution to overcome this challenge. We collect a large Raman spectroscopy dataset from 26 colorectal cancer patients with Raman shifts from 385 to 1545 cm-1. Second, dilated convolutional networks classify colorectal cancer tumour tissues. Following the deep learning model's output, we proceed by visualizing and analyzing the identified fingerprint peaks. Our deep learning algorithm exceeds previous colorectal cancer detection methods with 99.1% accuracy. Colorectal cancer detection using Raman spectra is unique. Our ensemble DCN could classify colorectal tumour and normal tissue Raman spectra. 2024 Author(s). -

Gaze and Queer Autonomy? Representations and Possibilities on New Visual Media Landscapes in the Indian Context
Representations of sexuality in Indian mainstream cinema tend to reinforce sexual differences, imbalances, and certain stereotypes that put queer identities in a disadvantageous position. The shift and transition from the monopoly of the state to an era of popular forms of entertainment enabled the centrality of debates on representations and sexuality. The study examines the representations of queerness that flourished on new visual media landscapes such as the OTT platforms Netflix and Amazon Prime Video that engaged in a new dialogue on queer representations and possibilities. The study attempts to analyze Super Deluxe (2019), Made in Heaven (2019) and Ajeeb Daastans (2021), as they become the representative form of cinema that marked the shift and engaged in a new dialogue on queer representations and possibilities. The study reads queer representation in light of the frameworks of gaze and homophyly to understand why they might offer different opportunities for representation and gaze.

Cultural Violence, Violent Gendering, and Abjection: Discourses on Sites of Violence through Trans Womens Narratives from India
The conventional cultural construct of gender and sexuality embedded in the dichotomous paradigm makes it challenging for people with queer and trans identities to fit into an assigned social role. Violent gendering takes place where women are seen as secondorder beings, disciplined and controlled by men, the first-order beings. The process of feminization and femininity is linked to women, which fixates on the idea that one is born a woman rather than one becomes a woman. This violent process of acculturation to these set norms comes with a lot of vulnerability for trans people in the form of abiding by the parameters of femininity and the threat of physical violence against their intersecting and transitioning bodies. Kristevas conception of abjection can be used to understand the discriminatory behavior against outcasts whose sexual or gender practices fall outside of the normative standards and conventions. At the same time, cultural violence, which Charlotte Bunch (2015) describes, is the culturally embedded practice and assumption of domination over women in virtually all societies. She also emphasizes that there is a need to understand that all violence against women is supported by cultural attitudes, which she argues is the real cultural challenge of violence. Keeping in perspective the idea put forth by Bunch, this article critically examines the violence reinforced by culture, and the process of gendering, with a central focus on the intersectional experiences of trans bodies as abject between gender, sex, and culture. This leads to the systematic violence enacted upon them by the invisible disciplinarians. The article considers 21st-century trans womens narratives, Laxmi Narayan Tripathis Me Hijra, Me Laxmi (2015) and Red Lipstick: The Men in my Life (2016). This article contextualizes and situates trans narratives, which provide insight into how trans womens bodies are seen as abject and have gone through the violent process of gendering and culturing 2022 Journal of International Womens Studies -
Female masculinities and women of third nature: Analyzing the gender and sexual politics of identity and visibility of alternative masculinities through indian mythologies and literary narratives
Alternative sexualities have been a part of the Indian past since time immemorial, and mention of them is often visible in Sanskrit mythological texts. As much as the presence of hijras and other gendered cultural identities is in Indian and Western public discourses, there is a narrow space occupied by women of the third kind with female masculinities, with scant attention leading to the higher invisibility of women of the third kind. Female masculinity is often considered a "rejected shred, " while male masculinity is seen as real and heroic. This chapter focuses on "masculinity without men" to explore alternative masculinities-the concept popularized by Judith Halberstam (Judith Halberstam, Female Masculinity. Zubaan Books, New Delhi, 1998). We delve into the politics of alternative modes of enactment and production where male masculinity is embedded. This chapter centers on female masculinity and alternative forms of masculinities performed, enacted, and embodied by female individuals as reflected in the Indian past and mythology. This chapter further delves into identifying histories and representations of female masculinities in Indian literature to bring female masculinities and women of the third kind into academic discourse.

Feminist Mobilization and Digital Feminism: Reading the Role of Digital Spaces as Catalysts for Feminist Action and Social Change
In the dynamic and evolving digital landscape, digital platforms and social media have had a transformative impact on feminist activism, representa-tion, and women's interactions in digital spaces. These digital technologies provide a space for self-expression, representation, and offer unparalleled opportunities for women's emancipation and change. However, there is also a rise of online harassment, which presents a counterbalance to these advancements. The study explores the ways in which women explore and engage with, and are affected by, digital platforms, social media, and tech-nology in the spheres of activism, visibility, and online harassment. These digital spaces and online communities make personal experiences more public and create spaces for a variety of voices to coexist which can be seen as promoting gender sustainable perspectives which integrates an ecosystem where women's emancipation and well-being thrive together. This study seeks to unravel the interplay between digital platforms, feminism, and women's collective experiences in online spaces, offering a nuanced under-standing of the challenges and a source of sustainable opportunities posed by technology in contemporary feminist discourse. In addition, the study aims to highlight the transformative potential of digital technologies for women's empowerment, visibility, and activism and create communities for change. By examining women's sustainable engagement with digital platforms in an Indian context through social media such as Instagram, the study contributes to a deeper comprehension of how technology shapes feminist activism, self-representation, and the broader feminist movement in the digital age. 2026 Dhishna Pannikot.
