This book comprehensively reviews current and novel treatment strategies against human parasites, including protozoans and helminths, using natural products. The initial chapters summarize the conventional treatment strategies and natural-product based therapeutics against these parasites. It discusses biochemical tools and techniques for the discovery of natural product based drugs against human parasites. The book also covers the ingenious and innovative mechanisms to achieve drug resistance by the protozoan parasites and strategies to overcome the resistance. It entails mechanistic insight into the modulation of host immune responses to delay or inhibit parasite clearance and explores host-pathogen interactions that mediate immunity against subsequent parasite challenge. In turn, the volume helps in understanding the immunobiology of the parasites and tools to identify candidate vaccine antigens and novel delivery systems against the protozoan parasites. Lastly, it explores the role of advanced methods, including nanotechnology, marine bioprospecting, and microorganisms-derived biochemicals against the protozoan parasites.This book is useful for students and researchers of pharmacology, parasitology, zoology and other allied fields.¿

As food producers, plants are constantly under attack by insects. Over the course of evolution, plants have not only developed a sophisticated defense apparatus but have also refined biochemical defense mechanisms to protect themselves, thereby maintaining the ecological balance. Plant-pest interactions induce an elaborate array of reactions involving the release of volatile compounds, effector and signaling molecules, trans-membrane proteins, and a variety of enzymes and hormones. This book offers a comprehensive guide to the strategies that plants employ against insects and other pests to ensure their continued survival. Addressing an important gap in the literature, it shares the latest findings in the field of plant-pest interactions for a broad audience. Providing an overview of the current state of knowledge on plant-pest interactions and their role in the genetic improvement of crops, it offers an essential guide for researchers and professionals in the fields of agriculture, plant pathology, entomology, cell biology, molecular biology and genetics.

कविता की गर्माहट आपको पूरे संग्रह में मिलेगी, जिसमें डॉक्टर अर्चना राकेश सिंह का मन, अनुभव, चेतना, दृष्टि सब शामिल है. यही कहना चाहूंगा कि हां यह कविता ही है ....! प्रताप सोमवंशी (कार्यकारी संपादक, हिन्दुस्तान) यह मात्र कविताएँ नहीं हैं, यह सरल शब्दों में लिखी गहरी सोच है. आज मैं अर्चना मैम का कवियित्री रूप देखकर स्तब्ध हूँ, निशब्द हूँ और उनका छात्र होने के नाते गौरवान्वित महसूस कर रहा हूँ. आयुष्मान ख़ुराना (फिल्म अभिनेता, गायक) उनकी कविताओं में प्रकृति, प्रेम और करुणा का ऐसा संगम है जिसको जब भी पाठक आत्मसात करने बैठे तब समझो वो उसका जीवन है जो इन कविताओं के माध्यम से एक बार फिर आंखों के आगे से गुजरने लगता है. इन कविताओं में वही सपने शामिल हैं जिनके ख़्वाब पाठकों ने देखे थे कभी. उनकी लेखनी में हर आम जन मानस का अक्स छुपा है कहीं न कहीं. डॉक्टर मंजू डागर चौधरी, कार्यकारी संपादक (अंतर्राष्ट्रीय मामले) कॉर्पोरेट इनसाइट आयरलैंड डॉक्टर अर्चना, जो अपने छात्रों के लिए हमेशा उनकी चहेती 'अर्चना मैम' रहेंगी अपने जीवन के खट्टे-मीठे अनुभव बहुत सहजता से अपनी कविताओं में पिरो देती हैं और अपने पाठकों को अपने संग एक मनोरम सफ़र पर ले जाती है. `मातृभाषा का प्रभाव' और `ज़ुर्राबें ' मेरी सबसे पसंदीदा कविताएँ हैं. ज्योति कपूर (फिल्म पटकथा लेखक) बधाई हो, गुड न्यूज़ इत्यादि This collection of poems by Prof. Archana R. Singh, from School of Communication Studies, Panjab University is an expression of her sensitivity, creativity and intellectual capacity to understand the modern society. They are unputdownable.

The Gangetic catfish, Clupisoma garua is commercially important inland water teleostean fish which is one of the most dominate species of catfish fishery in Ganga River system. The fish is largest species among the five species known to occur in India, and is considered to be a good table fish throughout the India and neighbouring countries, which fetches a good price in the market. The catch sold in the market comes from the natural stocks. Despite its abundance, consumer demand and palatability, very little information is available on the biology of this fish. The present situation demands the application of scientific method for its culture, but, it is inconceivable without a good knowledge of its biology. This book covers the findings and reviews of various aspects of fishery and biology such as food and feeding habits, reproduction and length and weight relationship of the fish. The book will be useful for those who are working in the field of aquaculture. Each chapter of the book focuses on the basic and current status of the knowledge based on the concerned topics. Hopefully the book will be beneficial not only for academicians but also for industrialists and professionals.
