A rare presentation of the Klinefelter's syndrome

A 16 years old boy with Chronic Renal Failure (CRF) was not suspected of having Klinefelter's syndrome until he complained of painful gynecomastia. He was under haemodialysis for 2 years. At first, he was in an approximately full pubertal development (P5, G5), but he had a small and a firm testis (length 2.2cm) and some degree of facial male pattern hair. He also had a decreased upper to lower body segment ratio and despite having chronic renal failure, he was taller than his parents and siblings. His laboratory tests showed high levels of FSH and normal levels of LH and testosterone. With regards to all these findings, we suspected that there might be an occult Klinefelter's syndrome. So, we made his karyotype that showed a 47XXY pattern. Because there are only a few number of cases that have occult Klinefelter's syndrome in the basis of chronic renal failure, we decided to report this case

Shea (Vitellaria paradoxa C.F. Gaertn.) – a peripheral empire commodity in French West Africa, 1894–1960

Burkinabé women have traded shea kernels and shea butter in periodic local markets, and on a regional scale with the densely-populated West African littoral, for centuries. This paper traces the origins of French colonial efforts to develop shea as a commodity of empire from the 1890s to independence in 1960. Colonial effo rts to incorporate Upper Volta, a French colonial backwater, into the world economy was drawn out, heterogenous, and messy. The colonial state assumed erroneously that little shea trade existed, and that producers would respond positively to market incentives. Yet, we suggest that French colonial policies failed due to a composite of factors including the limited investment in either the colony or shea as an oilseed crop, adaptation by women shea producers to the extraction of male labour and the trade opportunities created by new international borders, and the ‘blindness’ of colonial officials to the economic, social and cultural functions of periodic local markets used by women shea traders. The historical trajectory of the shea trade continues to have implications for current-day shea markets and their actors

Shea (Vitellaria paradoxa C.F. Gaertn.) – the emergence of global production networks in Burkina Faso, 1960–2021

After Burkina Faso’s independence, shea butter continues to be the key staple edible oil used by Burkinabe households although alternatives are now being placed in local markets. Shea (Vitellaria paradoxa C.F. Gaertn.) is primarily managed as a food tree crop for African consumers but has been promoted as a wild and abundant crop which gives African women cash and empowerment. New international demand for edible Cocoa Butter Equivalents (CBEs) from the 1960s onwards led to the introduction of several state-led efforts to regulate and control the shea trade through stabilization funds and parastatal marketing boards. These were abandoned after 1984, when cocoa prices collapsed and shea markets were liberalized. Increasingly since 2003, several leading Trans-National Corporations that manufacture CBEs are involved in sourcing shea kernels to meet the growing demands of the multi-billion-dollar confectionary and cosmetics industries. Burkina Faso and Ghana are two of the main exporting countries producing 60–75% of all international shea offtake. West, Central and East African women shea collectors and their associations have also managed, more recently, to meet the growing demand for ‘hand-crafted’ shea butter for the global personal care sector and new niches in the edible oil industry. Attempts to explain the radical transformation of shea supply chains in West Africa have focused on relatively recent events and actions detached from the broader historical context in which they are embedded. This paper adopts a broad periodization, stemming from the formulation of CBEs incorporating shea and palm stearin in the 1960s, and using a Global Production Network approach to understand the role and position of women shea producers and their associations at the intersection of global, regional, and local periodic markets. It challenges the assumption that global markets are necessarily a more viable alternative to reliance on local, domestic, or regional markets. The growth of global trade in shea kernels and shea butter has been accompanied by significant land cover and land use changes which has led to the progressive loss of trees, biodiversity, and other ecosystem services such as pollination and carbon sequestration. This presents new socio-economic challenges, including threats to local food and nutrition security, tenure rights and the livelihoods of local communities

EXPERIMENTAL SEARCH FOR A HEAVY ELECTRON.

A search for a heavy electron of the type considered by Low and Blackmon has been made by studying the inelastic scattering of 5 BeV electrons from hydrogen. The search was made over a range of values of the mass of the heavy electron from 100 to 1300 MeV. No evidence for such a particle was observed. Upper limits on the production cross sections were determined and employed to deduce limits on the values of the electron-photon-heavy electron coupling constant in Low and Blackmon's theory
