BACKGROUND The present study was undertaken to evaluate the accuracy of methods proposed by Tanaka and Johnston, Moyers, and Bernabé and Flores-Mir to forecast the mesiodistal dimensions of permanent canine and premolars in a North Indian population. METHODS Mesiodistal tooth dimensions were measured from study models representing 68 male and 68 female subjects (aged 12-16 years) of North Ind...

BACKGROUND & OBJECTIVES Studies conducted to assess the prevalence of cardiovascular (CV) risk factors among different regions of the country show variation in risk factors in different age groups and urban and rural population. We undertook this study to determine the prevalence of cardiovascular risk factors among urban adults in a north Indian city. METHODS In a cross-sectional survey, 222...

South Asian populations harbor a high degree of genetic diversity, due in part to demographic history. Two studies on genome-wide variation in Indian populations have shown that most Indian populations show varying degrees of admixture between ancestral north Indian and ancestral south Indian components. As a result of this structure, genetic variation in India appears to follow a geographic cl...

The prevalence of gallbladder cancer, the commonest biliary malignancy, shows geographical and racial variations. It is reported to be rare in India. However, the incidence of gallbladder cancer in north and central India is very high--it is the commonest gastrointestinal cancer in women. Even Indian migrants to different countries have a higher risk of having gallbladder cancer as compared to ...

BACKGROUND The vitamin D receptor (VDR) gene is a candidate gene for susceptibility to several diseases. Studies on association between VDR polymorphisms and risk of type 2 diabetes (T2DM) in different ethnic populations are yet inconclusive. AIMS This study was conducted to evaluate association between VDR polymorphisms and genetic susceptibility to T2DM in the north Indian population. SET...

The SW Indian Ocean contains at least four layers of water masses with different sources: deep Antarctic (Lower Circumpolar Deep Water) flow to the north, midwater North Indian Deep Water flow to the south and Upper Circumpolar Deep Water to the north, meridional convergence of intermediate waters at 500-1500 m, and the shallow South Equatorial Current flowing west. Sedimentation rates in the a...

During El Niño-Southern Oscillation (ENSO) events, atmospheric teleconnections associated with sea surface temperature (SST) anomalies in the equatorial Pacific can influence the ocean thousands of kilometers away. We use several data sets to delineate this “atmospheric bridge” between ocean basins, focusing on two emerging research areas: 1) the evolution of atmosphere-ocean interactions in th...

The Shillong Plateau (northeastern India) constitutes the only significant topography in the Himalayan foreland. Knowledge of its surface uplift history is key to understanding topographic development and unraveling tectonic–climate–topographic coupling in the eastern Himalaya. We use the sedimentary record of the Himalayan foreland basin north of the Shillong Plateau to show that the paleoBrah...

[1] The responses of tropical cyclone (TC) potential intensity (PI) and the associated environmental control parameters over the North Indian Ocean (NIO) to the doubled CO2 concentration are assessed based on the ensemble simulation from 15 coupled general circulation models (CGCMs) participated in the Intergovernmental Panel for Climate Change (IPCC) Forth Assessment Report (AR4). The results ...

Aim. The purpose of this study was to investigate the prevalence of transmigrated canines in a north Indian population and association with gender, side, associated pathologies, and dental anomalies. Subjects and methods. The prospective study consisted of panoramic radiographs of 3000 patients from two dental colleges in north India. The panoramic radiographs were screened for radiographically...
