Decreased bone mineral density (BMD) in astronauts returning from long-duration spaceflight missions has been well documented, but the altered mechanical loading environment experienced by the musculoskeletal system, which may contribute to these changes, has not been well characterized. The current study describes the loading environment of the lower(More)
The prevalence and bionomics of known Indian malaria vector anophelines was studied in three forest fringe villages in Sonitpur district of Assam, India. Anopheles philippinensis/nivipes (36.8%) and An. annularis (25.6%) were the most abundant of the seven vector anopheline species recorded. Densities of vector anophelines in general were high during(More)
BACKGROUND & OBJECTIVES Container-breeding mosquitoes, especially Aedes spp are vectors of diseases such as dengue and chikungunya. The abundance of these disease vectors in an area depends on the availability of container habitats and their physicochemical characteristics. The species composition of container-breeding mosquitoes in Asom, India was studied(More)
Ovitraps baited with hay and leaf infusions were evaluated for enhancing the oviposition response of gravid females of the dengue vector Aedes albopictus. The egg density per trap (mean ± SEmean) was the highest with 30% infusions of Pennisetum grass hay (623.6 ± 41) and rice straw (580 ± 51.3), which corresponded to oviposition activity index (OAI)(More)
BACKGROUND & OBJECTIVES Paramilitary operations along the Indo-Bangladesh border are adversely affected by malaria induced morbidity and mortality. Villages surrounding the paramilitary installations often serve as disease reservoirs. Malaria incidence in Tripura State Rifles (TSR) units in Dhalai District of Tripura was studied and the role of the village(More)
Long-duration exposure to microgravity has been shown to have detrimental effects on the human musculoskeletal system. To date, exercise countermeasures have been the primary approach to maintain bone and muscle mass and they have not been successful. Up until 2008, the three exercise countermeasure devices available on the International Space Station (ISS)(More)
Cotton leaf curl disease (CLCuD) outbreaks caused by CLCuD associated begomoviruses (CABs) significantly constrain cotton production in India and Pakistan. In comparison to the CABs circulating in Pakistan, molecular epidemiology, evolution and recombination patterns of CABs circulating in India are less studied. In this work, we characterized CAB complex(More)
Malaria epidemiological surveys were conducted in 16 villages along the Indo-Bangladesh border in Tripura, northeastern India. Insecticide resistance among malaria vectors and chloroquine resistance in the parasite were also studied along with monitoring of vector density using light traps. The epidemiological data indicated that malaria incidence was(More)
BACKGROUND & OBJECTIVES Dengue is an arboviral disease of public health importance in many parts of India and recently many cases have been reported from northeastern India. Aedes mosquitoes, which are the vectors of dengue, are widely prevalent in the region. A study was initiated in Sonitpur district of Assam to understand the spatiotemporal distribution(More)
