Scientific Staff of the Institute 76 Preface I am delighted in presenting the Annual Report of the National Institute of Malaria Research for the year 2012–13. During the reported year, the work on Quality Assurance of Malaria Rapid Diagnostic Tests in India in collaboration with National Vector Borne Disease Control Programme and to study the Safety and Efficacy of Artesunate + Mefloquine and Artesunate + Sulphadoxine-Pyrimethamine for the treatment of falciparum malaria in pregnancy was carried out. Studies on parasite biology on aspartic protease are inhibited by NOS donors and activators. This activity may provide a new approach for the mechanism of killing malaria parasites. The Centre for the Study of Complex Malaria was established at NIMR in collaboration with New York University and Pennsylvania State University, with the National Institute of Health, USA. The project for the Development of plant-based immersion oil for microscopy in collaboration with Forest Research Institute, Dehradun and Development of botanical insecticide formulation of essential oils extracted from Lantana camara and Valeriana jatamansii and Psoralea corylifolia for the control of mosquitoes with Defence Research Laboratory, Tezpur (Asom) is undergoing. Assessment of the effectiveness of intensive intervention measures on malaria control programme in the tribal district, Balaghat, Madhya Pradesh in collaboration with Regional Medical Research Centre for Tribals, Jabalpur is being conducted. Standardization of molecular and biochemical techniques for characterization of resistance has been initiated and the study is in progress. The strain of Anopheles stephensi was sequenced by using voltage-gated sodium channel. Overall emphasis is being laid on research projects with operational and translational approach. The Institute had received extramural grants from various national and international agencies like National Vector Borne Disease Control Programme, MMV, Geneva, Michigan University (USA), Institut Pasteur, Paris and State Governments of Rajasthan and Gujarat, etc. On the request of NDMC/MCD, Delhi, NIMR undertook Entomological surveillance for Aedes and the breeding habitats mapped. The work on Health Impact Assessment of Narmada Basin Dam and rehabilitation of colonies was undertaken at Jabalpur, Bhopal and Narmada Nagar, and Sardar Sarovar project areas of Narmada canal in Rajasthan. The activities were continued for providing support to the programme. The Journal of Vector Borne Diseases, published by the Institute got an impact factor of 1.04 for the reported year. NIMR organised a workshop on Comprehensive Case Management in Odisha. The outcome of the project is very significant in terms of demonstrating reduction in malaria with management using usual resources with better supervision. The Institute continued the activities of human resource development by imparting trainings to various health personnel, district programme officers, VBD consultants, laboratory technicians, guiding research scholars, and M.Sc. students etc. I take this opportunity to thank all the scientists and staff for their valuable support in all the activities. We are also grateful to the Secretary, Department of Health Research and the Director General, Indian Council of Medical Research for his continued support and encouragement. I also thank the Annual Report Committee, and the Publication Division of NIMR for bringing out this report.
