Metagenomics for Legume Crop Improvement offers a comprehensive and timely exploration of the enormous potential hidden within legume-associated microbial communities. Legumes play a crucial role in global food security and sustainable agriculture due to their natural symbiosis with nitrogen-fixing and plant growth–promoting microbes. Yet, despite their significance, the microbiomes surrounding legumes remain poorly understood. This book aims to bridge that gap by bringing together cutting-edge research, analytical tools, and practical applications of metagenomics, a transformative approach that allows the direct study of entire microbial communities without the need for cultivation. The book provides an interdisciplinary perspective, integrating plant science, microbiology, biotechnology, and bioinformatics to reveal how metagenomic insights can enhance legume productivity, resilience, soil health, and long-term sustainability. It uniquely combines foundational concepts with advanced methodologies and real-world agricultural relevance, making it stand out as a vital reference for emerging research in plant–microbe interactions.Key Features:Provides a holistic overview of legume-associated microbiomes, including microbial ecology, nutrient cycling, and stress responses.Highlights advanced metagenomic techniques, sequencing platforms, and bioinformatics tools tailored for legume research.Explores how environmental stresses such as extreme pH, nutrient deficiencies, fertilizers, and climate stressors shape legume microbiomes.Introduces integrative “omics” approaches (metagenomics–metabolomics) to uncover microbial functions and plant interactions.Written for researchers, graduate students, academicians, and agricultural practitioners, this book serves as both an educational resource and a practical guide. By connecting scientific discovery with field-level applications, Metagenomics for Legume Crop Improvement provides the knowledge needed to harness beneficial microbes for sustainable farming and future-ready legume cultivation. It is an essential addition to the libraries of professionals working in plant science, microbiome research, and agricultural biotechnology.

"A Handbook of Tricuspid And Pulmonary Valve Disease" contains a detailed description of the diseases of these two valves. A detailed description of Ebstein''s Anomaly Of Tricuspid vale is highlight of this book. Etiology, pathogenesis and hemodynamics of diseases of both valves have been dealt in simple and comprehensible manner. Special effort has been made to explain the clinical features (Symptoms and signs) of disease. Probably the clinical features is the forgotten art in the newer text books. However, the author has taken a special interest to include a detailed description of clinical features. The treatment section includes description about the various interventions (catheter based as well as surgical) and it also includes the ACC / AHA guidelines. Like his previous two handbooks (A handbook of Rheumatic Fever and A Handbook of Aortic valve Disease), this book also has extensive description of all aspects of the disease. A small chapter about ''Straight Back Syndrome'' has also been included in this book. All in all, the book promises to be a great reference book for Aortic Valve disease and is worth having it on shelf for easy reading. The point wise and concise writing has made this book specially useful for students and exam going students

"A Handbook of Multivalvular and Prosthetic Valve Disease" contains a detailed description of the disease. There are no clear cut guidelines about management of multivalvular disease. However, author has tried to deal in simple and comprehensible manner. Special effort has been made to explain the clinical features (Symptoms and signs) of multivalvular disease and to decide about dominant lesion in each case. Likewise, the prosthetic valve evaluation has also been dealt in great details in this book. Readers will find it very useful as current books lack a detailed description of prosthetic valves. Prosthetic valve dysfunction, its assessment and management is again highlight of this handbook. The treatment section includes description about the various interventions (catheter based as well as surgical) and it also includes the ACC / AHA guidelines whereever possible. All in all, the book promises to be a great reference book for multivalvular and prosthetic Valve Disease and is worth having it on shelf for easy reading. Pointwise and concise writing has made this book specially useful for students and exam going students.

Mitral stenosis is due to thickening and immobility of the mitral valve leaflets, resulting in obstruction in blood flow from the left atrium to the left ventricle. The mitral valve leaflets are thickened and the commissures are fused along with thickening and shortening of the chordae tendineae. This mechanical obstruction leads to increases in pressure within the left atrium, pulmonary vasculature, and right side of the heart; in comparison, the left ventricle is unaffected if there is pure mitral stenosis.

A Handbook of Aortoarteritis and Ruptured Sinus of Valsalva contains a detailed description of these diseases. Aortoarteritis is a relatively common disease in Indian subcontinent. It is a common cause of dilated cardiomyopathy in this region. It has various presentations due to stenotic involvement of aorta and its branches. Ruptured sinus of Valsalva although rare but has catastrophic clinical presentation. These diseases require early recognition and diagnosis to optimize management of patients. Current text books lack a detailed description of these diseases. Special efforts have been made by the author to give a thorough overview of these diseases. Clinical features (Symptoms and signs), investigations, natural history, prognosis as well as management have been dealt in details. Clinical features are probably the forgotten art in the newer text books. However, the author has taken a special interest to include a detailed description of clinical features. The treatment section includes description about the various interventions (catheter based as well as surgical). The author has published a series of handbooks on Rheumatic fever and Valvular heart diseases from AuthorHouse. Like his previous books, this book also has extensive description of all aspects of the disease.All in all, the book promises to be a great reference book for Aortoarteritis and Ruptured sinus of Valsalva and is worth having it on shelf for easy reading. The point wise and concise writing has made this book useful for students especially exam going students.
