RESUMO

Having close friends in the third age as in any other period of life consistently corresponds with happiness and satisfaction. Friends provide support, companionship, and acceptance, which are crucial to older adults' sense of self-esteem. Having close friends positively affects the psychological well-being of older adults. Friends are named as the people with whom older adults enjoy spending time, engage in leisure activities, and have daily or frequent contact and who have the most positive and significant impact on well-being. Research suggests that adults' views of social relationships are likely to vary with age. As friendship patterns are affected by age, perceptions of friendship also get affected with it. Gender is the other important factor affecting the perceptions of friendship. This paper seeks to understand the elements involved in older adults’ perception of friendship relationships by analysing the definitions of. Friendship provided by the participants. The research also explored the problems affecting the friendship relationships of the elderly and the factors causing such problems.

RESUMO

Lung cancer is one of the leading causes of cancer related death in most developed and many developing countries of the world. Due to lack of validated screening methods and poor prognosis, treatment of lung cancer has not improved significantly over the last two decades. Therefore the risk of the disease needs to be minimized by preventive measures. One approach for lung cancer prevention envisages reversal or restriction of precancerous lesions by chemopreventive intervention. It demands a deeper understanding of the pathogenesis of the disease and identification of the ideal point of intervention. In the present investigation, tea components, epigallocatechin gallate (EGCG) and theaflavins (TF) were assessed for their chemopreventive potential when administered in the post initiation phase of lung carcinogenesis in an experimental mouse model. Histopathological changes in lungs of mice administered benzo(a)pyrene (BP) were followed serially and correlated with the expression of Cox-2, caspase-3 and caspase-7, which play key roles in histopathogenesis of neoplasia. The observations strongly indicate that both EGCG and TF can influence the expression of these genes to modulate the process of carcinogenesis, resulting in delayed onset and lowered incidence of pre-invasive lung lesions.
