BACKGROUND Evidence of an association between fish and meat consumption and risk of dementia is inconsistent and nonexistent in populations in developing countries. OBJECTIVE The objective was to investigate associations between fish and meat consumption with dementia in low- and middle-income countries. DESIGN One-phase cross-sectional surveys were(More)
The anticancer effects of human amniotic membrane (hAM) have been studied over the last decade. However, the action mechanisms responsible for these effects are not fully understood until now. Previously results reported by our team proved that hAM is able to induce cytotoxicity and cell death in hepatocellular carcinoma (HCC), a worldwide high incident and(More)
The fullerene molecule belongs to the so-called super materials. The compound is interesting due to its spherical configuration where atoms occupy positions forming a mechanically stable structure. We first demonstrate that pollen of Hibiscus rosa-sinensis has a strong symmetry regarding the distribution of its spines over the spherical grain. These spines(More)
Liver, the largest intern organ of the human body, is responsible for several vital tasks such as digestive and excretory functions, as well as for nutrients storage and metabolic functions, synthesis of new molecules and purification of toxic chemicals. Cirrhosis, fibrosis and hepatocellular carcinoma are the most prevalent liver diseases. Despite all the(More)
We apply the Wigner formalism of quantum optics to study the role of the zeropoint field fluctuations in entanglement swapping produced via paramet-ric down conversion. It is shown that the generation of mode entanglement between two initially non interacting photons is related to the quadruple correlation properties of the electromagnetic field, through(More)
