Patterns and Trends of Childhood Cancer Incidence (0-14 Years) in Delhi, India: 1990-2014.

Objectives: To investigate the patterns and temporal trends of childhood cancer incidence (0-14 years) in Delhi from 1990 to 2014.

Methods: The new childhood cancer cases diagnosed between 1990 and 2014 were extracted from the Delhi population-based cancer registry (PBCR). Joinpoint regression analysis was performed to assess the temporal behaviour of new childhood cancer.

Trends and future burden of tobacco-related cancers incidence in Delhi urban areas: 1988-2012.

Introduction: Tobacco products are the major contributors for various cancers and other diseases. In India, tobacco-related cancers (TRCs) contribute nearly half of the total cancers in males and one-fifth in females.

Objective: The objective of the study is to investigate 25-year trends and projection of TRCs for 2018-2022.

Trends in Lung Cancer Incidence in Delhi, India 1988-2012: Age-Period-Cohort and Joinpoint Analyses.

Introduction: Lung cancer (LC) has been one of the most commonly diagnosed cancers worldwide, both in terms of new cases and mortality. Exponential growth of economic and industrial activities in recent decades in the Delhi urban area may have increased the incidence of LC. The primary objective of this study was to evaluate the time trend according to gender.

Inchworm bipedal nanowalker.

Nanowalkers take either inchworm (IW) or hand-over-hand (HOH) gait. The IW nanowalkers are advantageous over HOH ones in force generation, processivity and high-density integration, though both gaits occur in intracellular nanowalkers from biology. Artificial IW nanowalkers have been realized or proposed, but all rely on different 'head' and 'tail' to gain an adventitious direction.
