An updated insight into the Sialotranscriptome of Triatoma infestans: developmental stage and geographic variations
2014
Background Triatoma infestans is the main vector of Chagas disease in South America. As in all hematophagous arthropods, its saliva contains a complex cocktail that assists blood feeding by preventing platelet aggregation and blood clotting and promoting vasodilation. These salivary components can be immunologically recognized by their vector's hosts and targeted with antibodies that might disrupt blood feeding. These antibodies can be used to detect vector exposure using immunoassays. Antibodies may also contribute to the fast evolution of the salivary cocktail. Methodology Salivary gland cDNA libraries from nymphal and adult T. infestans of breeding colonies originating from different loc…

Obywatel a władza lokalna w pierwszym powojennym dziesięcioleciu na przykładzie gminy Kościeliska
2015
Artykuł poświęcony jest relacjom między władzą lokalną a obywatelem w pierwszym powojennym dziesięcioleciu w gminie Kościeliska, pow. oleski. Na początku autor charakteryzuje gminę, następnie podaje przykłady tych relacji na tle ówczesnej sytuacji politycznej, społecznej i gospodarczej. Najwięcej uwagi poświęca udziałowi i zaangażowaniu obywateli w działalność silnie upartyjnionych organów władzy lokalnej oraz w podejmowanych przez władze gminne wysiłkom na rzecz rozwiązania trudnych problemów społecznych i gospodarczych, z którymi borykała się ludność gminy. Władze gminne miały jednak ograniczone możliwości rozwiązania tych problemów, co skutkowało bardzo złymi nastrojami społecznymi, któr…

Immune Modulating Effects of NKT Cells in a Physiologically Low Dose Leishmania major Infection Model after αGalCer Analog PBS57 Stimulation
2014
Leishmaniasis is a parasitic infection affecting ∼12 million people worldwide, mostly in developing countries. Treatment options are limited and no effective vaccines exist to date. Natural Killer T (NKT) cells are a conserved innate-like lymphocyte population with immunomodulating effects in various settings. A number of reports state a role of NKT cells in different models of Leishmania infection. Here, we investigated the effect of NKT cells in a physiologically relevant, intradermal low dose infection model. After inoculation of 103 infectious-stage L. major, comparable numbers of skin-immigrating NKT cells in both susceptible BALB/c mice and resistant C57BL/6 mice were noted. Compared …
Tuberculosis among Migrant Populations in Sicily: A Field Report
2021
Background. In the EU, tuberculosis (TB) mainly affects vulnerable people, including migrants. From 2014 to 2017, we have estimated the frequency of both tuberculosis and latent tuberculosis infection (LTBI) among the migrant population hosted in 41 reception centers in western Sicily (ITaCA network). Materials and Methods. All migrants were consecutively recruited for the screening of TB infection with physical examination and TST in 1,020 migrants and with IGRA in the others 2,690. The screening was carried out 4–8 weeks after landing in Sicily. For all migrants with a positive screening test, chest X-ray and smear examination were performed. LTBI was defined by positivity of TST or IGRA …
