A 48-week study of fat molecular alterations in HIV naïve patients starting tenofovir/emtricitabine with lopinavir/ritonavir or efavirenz: Greater deleterious effects of efavirenz.

S’han descrit informes contradictoris sobre els efectes d’Efavirenz (EFV) i lopinavir/ritonavir (LPV/r) al teixit adipós subcutani (SAT). L’objectiu d’aquest estudi era evaluar els efectes moleculars i clínics de LPV/r i EFV, tots dos en combinació amb tenofovir/emtricitabina (TDF/FTC), sobre el SAT dels pacients infectats per VIH sense tractament antirretroviral previ. Després de 48 setmanes de tractament, TDF/FTC més LPV/r va augmentar de forma significativa el greix de les extremitats i els paràmetres lipídics, mentre que TDF/FTC/EFV només va augmentar de forma significativa el colesterol total i LDL. La expressió dels gens implicats en la diferenciació dels adipòcits i dels gens relacionats amb la mitocondria no va canviar de forma significativa en el SAT dels pacients exposats a LPV/r, mentre que Cyt b i els gens relacionats amb la imflamació estaven estimulats de forma significativa en el SAT dels pacients exposats a EFV.

Between specialization and globalization. The marketing of agrarian products and its environmental impacts seen from a historical perspective: the province of Barcelona in the mid-nineteenth century

Ecological economics has five good reasons to consider that economic globalisation, spurred by commercial and financial fluxes, to be one of the main driving forces responsible for causing environmental degradation to our planet. The first, is the energy consumption and the socio-environmental impacts which long-distance haulage entails. The second, is the ever-increasing flow of goods to far-away destinations which renders their recycling practically impossible. This is particularly significant, because it prevents the metabolic lock of the nutrients present in food and other agrarian products from taking place. The third, is that the high degree of specialization attained in agriculture, forestry, cattle, mining and industry in each region, generates deleterious effects not only on the eco-landscape structure of the uses of the soil, but on the capability to provide habitat and environmental functions to maintain biodiversity as well

The effect of university culture and stakeholders' perceptions on university-business linking activities

The present work discusses the effects of university culture and structure on university-business relations, focusing on knowledge transfer activities. It puts forward the thesis that when links between university and business are introduced into the university system as a turn-key proposition rather than as developmental process, the prevailing university culture and structure will exert resistance against change and will oppose the creation of appropriate structures to promote them, with deleterious effects for the university.
