Role of Boron as Priming Agent on Biochemical and Antioxidant System in Two Wheat Varieties Against Heat Stress
(Springer, 2023) Payal Chakraborty; Padmanabh Dwivedi
In agriculture, the selection of healthy and vigorous seeds is critical, so seeds must be of high quality. Seed priming is a reliable and commercial strategy for improving seed germination and seedling establishment under stressful conditions, whether biotic or abiotic. Heat stress occurs when temperature rises above a particular point and results in permanent irreversible damage to plants, whereas, heat stress that primarily affects crops during their reproductive or grain-filling stages, is referred as terminal heat stress. The present experiment deals with treating two varieties of wheat (HUW-468: Temperature sensitive and HUW-510: Temperature resistant) using boric acid and borax as priming agents and evaluating their effect on different parameters including biochemical (Hydrogen peroxide, Malondialdehyde, and Proline) and antioxidant parameters (Superoxide dismutase, Catalase, Ascorbate peroxidase, and Glutathione reductase) by sowing them under two different conditions (Timely and Late sown) for evaluating effect of priming agents on heat stress on different days of study. The results obtained indicate that primed seedlings grew better and were more resilient to stress, and this was due in part to lower ROS production, stronger membrane stability, a strong antioxidant defense system, and preservation of a strong and healthy crop stand. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
THE MUSICAL REPRESENTATION OF SRI LANKAN KAFFIRS
(Logos Verlag Berlin GmbH, 2023) Geethika Abeysekara; Chinthaka Prageeth Meddegoda
This study presents a very small community within the Sinhalese context of Sri Lanka in light of academic interest: the Kaffirs. Their communal history reaches far back into colonial times, and they did not distinguish clearly from which territories in Africa these Kaffirs, an expression introduced by Portuguese rulers for slaves and servants brought to Sri Lanka from African shores, came and how they identify. Currently, Kaffirs are seen through the gaze of public writings and common biases. They are believed to have their performance styles and their strong association with the drum, dance, and vocal genres integrated into the canon of Sinhalese traditions. One specific vocal expression is the singing of manja songs, which are introduced and roughly analysed in this short paper. Manja songs are not so widely known to all people living in Sri Lanka. A specific study of these songs has not yet taken place. The main methods used are micro-analysis, literature studies, and open interviews with those who are connected to Kaffirs, either as members of the group or as people related to their studies and performing arts. Beyond presenting the exciting text repertoire, it is to connect the musical skills that come with this way of singing with related arts such as dancing and drumming. The Kaffirs’ performance potentials are widely underestimated. Many Kaffirs were integrated, through marriage and social subordination, into the current society. Yet, it is important to focus on the snippets in the history of specific performance skills and their relatedness to another continent in order to help understand global issues and their future. © 2023, Logos Verlag Berlin GmbH.

An introduction to tantric philosophy: The Paramarthasara of Abhinavagupta with the commentary of Yogaraja
(Taylor and Francis, 2014) Lyne Bansat-Boudon; Kamaleshadatta Tripathi
The Paramarthasara, or 'Essence of Ultimate Reality', is a work of the Kashmirian polymath Abhinavagupta (tenth-eleventh centuries). It is a brief treatise in which the author outlines the doctrine of which he is a notable exponent, namely nondualistic Śaivism, which he designates in his works as the Trika, or 'Triad' of three principles: Śiva, Śakti and the embodied soul (nara). The main interest of the Paramarthasara is not only that it serves as an introduction to the established doctrine of a tradition, but also advances the notion of jivanmukti, 'liberation in this life', as its core theme. Further, it does not confine itself to an exposition of the doctrine as such but at times hints at a second sense lying beneath the evident sense, namely esoteric techniques and practices that are at the heart of the philosophical discourse. Its commentator, Yogaraja (eleventh century), excels in detecting and clarifying those various levels of meaning. An Introduction to Tantric Philosophy presents, along with a critically revised Sanskrit text, the first annotated English translation of both Abhinavagupta's Paramarthasara and Yogaraja's commentary. This book will be of interest to Indologists, as well as to specialists and students of Religion, Tantric studies and Philosophy. © 2011 Lyne Bansat-Boudon and Kamaleshadatta Tripathi.

A hybrid deep learning model for COVID-19 prediction and current status of clinical trials worldwide
(Tech Science Press, 2020) Shwet Ketu; Pramod Kumar Mishra
Infections or virus-based diseases are a significant threat to human societies and could affect the whole world within a very short time-span. Corona Virus Disease-2019 (COVID-19), also known as novel coronavirus or SARSCoV- 2 (Severe Acute Respiratory Syndrome-Coronavirus-2), is a respiratory based touch contiguous disease. The catastrophic situation resulting from the COVID-19 pandemic posed a serious threat to societies globally. The whole world is making tremendous efforts to combat this life-threatening disease. For taking remedial action and planning preventive measures on time, there is an urgent need for efficient prediction models to confront the COVID-19 outbreak. A deep learning-based ARIMA-LSTM hybrid model is proposed in this article for predicting the COVID-19 outbreak by utilizing real-time information from the WHO's daily bulletin report as well as provides information regarding clinical trials across the world. To evaluate the suitability and performance of our proposed model compared to other well-established prediction models, an experimental study has been performed. To estimate the prediction results, the three performance measures, i.e., Root Mean Square Error (RMSE), Coefficient of determination (R2 Score), and Mean Absolute Percentage Error (MAPE) have been employed. The prediction results of fifty countries substantiated the fact that the proposed ARIMA-LSTM hybrid model performs very well as compared to other models. The proposed model archives the lowest RMSE, lowest MAPE, and highest R2 Score throughout the testing, under varied selection criteria (country- wise). This article aims to contribute a deep learning-based solution for the wellbeing of livings and to provide the current status of clinical trials across the globe. © 2021 Tech Science Press.

Morphologies, crystal structure and antibacterial properties of chromium substituted zinc oxide nanoparticles synthesized by microwave method
(Elsevier Ltd, 2021) A. Prakasam; P.M. Anbarasan; R. Azhagu Raj; C. Ragupathi; Rajneesh Kumar
In this paper, we report on the synthesis on pure and Cr doped ZnO particles via the microwave method. Pure and Cr doped ZnO produced are monodisperse and versatile and were characterized with the help of FT-IR, XRD, SEM/EDX and TEM methods. Pure and Cr doped ZnO particles are crystalline in nature and average sizes were between 20 and 30 nm. Furthermore, the present work clearly indicated that the surface area to volume ratio and particle size variation of green ZnO nanoparticles are accountable for significantly increased antibacterial behaviour. © 2021 Elsevier Ltd.

Gene variants polymorphisms and uterine leiomyoma: an updated review
(Frontiers Media SA, 2024) Sonal Upadhyay; Pawan K. Dubey
Uterine leiomyoma, commonly referred to as fibroids, is a benign tumor that develops in the muscular wall of the uterus. These growths are non-cancerous and can vary in size, ranging from tiny nodules to larger masses. Uterine leiomyomas often occur during a woman’s reproductive years and can lead to symptoms such as heavy menstrual bleeding, pelvic pain, and pressure on nearby organs. While the exact cause is not fully understood, hormonal factors, particularly estrogen and progesterone, are believed to play a role in their development. The exploration of connections between genetic variants and uterine leiomyoma has captivated scientific attention for numerous years. The results from investigations remain a subject of intrigue within the scientific community. To date, the findings regarding the relationships between single nucleotide polymorphisms (SNPs) and uterine leiomyoma have exhibited some inconsistencies. However, amidst these inconsistencies, several promising outcomes have emerged that hold the potential to shape future research endeavors. These promising leads could pave the way for the development of innovative targeted therapies and novel prognostic biomarkers. This review specifically centers on accentuating the existing literature data concerning genetic variants that have been explored for their potential connections to uterine leiomyoma. Additionally, it underscores the prospects of employing genetic variations as diagnostic and prognostic biomarkers for individuals diagnosed with uterine leiomyoma.

Molecular Aberrations in Periampullary Carcinoma
(Springer India, 2017) Mallika Tewari; Jyoti R. Swain; V.K. Dixit; H.S. Shukla
Periampullary carcinomas are a group of rare lesions around the ampulla of Vater including distal bile duct and duodenum and are very different from pancreatic ductal adenocarcinoma clinically and pathologically, but the molecular alterations in these tumours are less known. Genetic alterations of the KRAS oncogenes, tumour suppressor genes p53, p16 and MADH4 (SMAD4/DPC4) and genome maintenance genes (MLHI, MSH2) are commonly altered in pancreatic adenocarcinoma and have also been described in periampullary cancers, although at lower frequencies. To understand the molecular characteristics of non-pancreatic periampullary carcinomas, ampullary cancers can now be further defined accurately into their intestinal and pancreatobiliary subtypes using histomolecular profiling. KRAS mutation, which occurs in most pancreatic cancers, is found to occur less frequently in ampullary (42–52%), biliary (22–23%) and duodenal cancers (32–35%). Mutations are also found in tumour suppressor genes (p53) and are associated with transformation of adenomas and low-grade carcinomas into high-grade carcinomas. Loss of DPC4 occurs late in ampullary carcinogenesis. This study summarizes the current knowledge in molecular aberrations in non-pancreatic periampullary cancers. © 2017, Indian Association of Surgical Oncology.
