Abstract

Orientation of cell and its actin fibres dictate various properties of the cell and its associated tissue including morphology, cell migration and response of cell to external stimuli. While the vital role of cell and actin fibre orientation has been demonstrated in various studies and across many cell-types, extracting this information from microscopy images is a challenging task. Although several methods have been developed to quantify alignment of a cell and its actin fibres from experimental images, all of them differ at one step or the other. We highlight the importance of orientation of cell and associated fibres and present a generic scheme of various approaches to assimilate the widely used methods. We have presented a systematic approach to determine cell and fibre orientation. The study will improve our understanding of the core processes and will also help in development of high throughput imaging methods to extract information from experimental images.

Abstract

The world is going through a demographic transition. During the last few decades, there has been a tremendous increase in the population of elderly persons. The reasons are multi factors: socio-economic progress, healthier life style, better environmental conditions, increased availability of high quality medical care, wide range of life saving drugs, new-surgical techniques and immunization programs have drastically reduced mortality rate and thus , increased life expectancy ( Bhandari , 1999). In such a scenario ,corporate hubs are started looking for these people as the future workforce. The ultimate goal of promoting longevity should be to improve quality of life, personal effectiveness and happiness Thus, the present study was planned with the aim to asses the level of happiness and personal effectiveness of personality typeA/B aging adults. The purposive sample comprised of 120 aging adults (60-70 years) who retired from government jobs. Equal number of male and female aging adults, having personality type A and B, belonging to middle SES were included in the sample. SES scale developed by Bhardwaj (2001) ,ABBPS developed by Dhar and Jain (1983) to measure personality type A and B, Personal effectiveness inventory developed by Pareek (2001) and Happiness scale by responses of the subjects. Percentages, mean scores, S.D. and‘t’ test were computed to analyze the data. Findings of the study revealed that personality type A males ( joint and nuclear families) and personality type B males (Joint families) were found to be high on self disclosure. Majority of females had low self disclosure irrespective of their personality type and family setup. Type A / B females (Joint and Nuclear families) and type B males were found to be more open to feedback. Majority of personality type A / B aging adults had low perceptiveness. Majority of females were found to be task obsessed irrespective of their personality type and family set up. Significant differences were found in openness to feed back among type B females and males living in nuclear and joint families. A significant gender difference was found in level of happiness of male and female aging adults living in nuclear and joint families. Both personality type A and B males were found happier in joint families whereas the reverse was true in case of females with personality A and B.
