HIV serostatus knowledge and serostatus disclosure with the most recent anal intercourse partner in a European MSM sample recruited in 13 cities: results from the Sialon-II study

Knowledge of HIV status can be important in reducing the risk of HIV exposure. In a European sample of men-who-have-sex-with-men (MSM), we aimed to identify factors associated with HIV serostatus disclosure to the most recent anal intercourse (AI) partner. We also aimed to describe the impact of HIV serostatus disclosure on HIV exposure risks. During […]

Enniatin B and ochratoxin A in the blood serum of workers from the waste management setting

The waste management occupational environment is recognized by the simultaneous presence of several substances and biologic agents. Therefore, workers are exposed simultaneously to multiple contaminants. It has also been reported occupational exposure to aflatoxin B1 in one Portuguese waste sorting plant. However, besides this mycotoxin, data regarding fungal contamination showed that exposure to other mycotoxins could […]

Spatial distribution of citizen science casuistic observations for different taxonomic groups

Opportunistic citizen science databases are becoming an important way of gathering information on species distributions. These data are temporally and spatially dispersed and could have limitations regarding biases in the distribution of the observations in space and/or time. The authors tested the influence of landscape variables in the distribution of citizen science observations for eight […]

Solute carriers affect Anopheles stephensi survival and Plasmodium berghei infection in the salivary glands

Malaria is caused by mosquito-borne Plasmodium spp. parasites that must infect and survive within mosquito salivary glands (SGs) prior to host transmission. Recent advances in transcriptomics and the complete genome sequencing of mosquito vectors have increased our knowledge of the SG genes and proteins involved in pathogen infection and transmission. Membrane solute carriers are key […]

Leishmania infantum exerts immunomodulation in canine Kupffer cells reverted by meglumine antimoniate

Kupffer cells (KC) are the liver macrophage population that resides in the hepatic sinusoids and efficiently phagocyte pathogens by establishing an intimate contact with circulating blood. KC constitute the liver host cells in Leishmania infection, nevertheless little is described about their role, apart from their notable contribution in granulomatous inflammation. The present study aims to […]
