    This book examines in detail many rhinologic issues that are not covered in other books, are still not completely understood, and can be difficult to deal with clinically. In each chapter, three authors – a young otorhinolaryngologist, a senior author, and an international expert – elaborate on a specific issue, such as the role of immunotherapy in treating nasal polyps, the management of rhinitis during pregnancy, how rhinitis can differ in adults and children, how to choose between open or endonasal rhinoplasty, the ideal form of anesthesia for nasal surgery, etc. The volume will appeal to a wide readership, from otorhinolaryngologists to allergists and facial plastic surgeons, as well as trainees and students in related fields

    Abstract The proteome composition of Echis carinatus carinatus venom (ECV) from India was studied for the first time by tandem mass spectrometry analysis. A total of 90, 47, and 22 distinct enzymatic and non-enzymatic proteins belonging to 15, 10, and 6 snake venom protein families were identified in ECV by searching the ESI-LC-MS/MS data against non-redundant protein databases of Viperidae (taxid 8689), Echis (taxid 8699) and Echis carinatus (taxid 40353), respectively. However, analysis of MS/MS data against the Transcriptome Shotgun Assembly sequences (87 entries) of conger E. coloratus identified only 14 proteins in ECV. Snake venom metalloproteases and snaclecs, the most abundant enzymatic and non-enzymatic proteins, respectively in ECV account for defibrinogenation and the strong in vitro pro-coagulant activity. Further, glutaminyl cyclase, aspartic protease, aminopeptidase, phospholipase B, vascular endothelial growth factor, and nerve growth factor were reported for the first time in ECV. The proteome composition of ECV was well correlated with its biochemical and pharmacological properties and clinical manifestations observed in Echis envenomed patients. Neutralization of enzymes and pharmacological properties of ECV, and immuno-cross-reactivity studies unequivocally point to the poor recognition of <20 kDa ECV proteins, such as PLA2, subunits of snaclec, and disintegrin by commercial polyvalent antivenom
