The present study is an endeavour to document the pattern of comparative advantage and structural changes of Indian exports with Africa with the help of revealed comparative advantage index and the constant market share model for the period 1980–2021. The results indicate that India possesses a comparative advantage in a large number of export products to markets in Africa. However, most of these exports belong to the category of low-tech and resource-based goods. Considering its abundant labour, it is to be expected for India to have a comparative advantage in these low-skilled and labour-intensive traditional exports. The commodities with maximum advantage in the African market are medicinal and pharmaceutical products followed by sugar, sugar preparations, and honey. In the category of technology-intensive products, India has strengthened its market power only in the export of organic chemicals and dyes, and colouring materials. [ABSTRACT FROM AUTHOR]

Introduction: Though, bladder cancer is one of the most common urological malignancies, studies addressing the young age group bladder tumors are rare. Present study was done to determine the clinicoepidemiological aspects of bladder tumor diagnosed in young age patients and to compare these aspects with elderly patients.Patients and Methods: Patients with urinary bladder tumor were selectively divided into two groups; young (<40 years) and elderly (>60 years). Groups were compared on various parameters and statistically analyzed using Fisher's exact two-tailed test.Results: Smoking, tea and coffee intake and exposure of dye were found significantly associated with development of bladder tumor. Most of the tumors in young age were small, solitary, and papillomatous. Transitional cell carcinoma (TCC) was the most common histological subtype, though most were of low grade and were non-muscle invasive in comparison to the tumors in elderly group.Conclusion: The incidence of bladder cancer is common in younger age group. Active and passive cigarette smoking, tea, coffee intake, and exposure to organic dyes are major risk factor for younger age group bladder tumor in this part of world. TCC is most common histological subtype and most of them are in low grade without muscle invasion. [ABSTRACT FROM AUTHOR]
