The phylogenetic proximity between Trypanosoma cruzi and Trypanosoma (Schizotrypanum) dionisii suggests that these parasites might explore similar strategies to complete their life cycles. T. cruzi is the etiological agent of the life threatening Chagas' disease, whereas T. dionisii is a bat trypanosome and probably not capable of infecting humans. Here we sought to compare mammalian cell invasion and intracellular traffic of both trypanosomes and determine the differences and similarities in this ...

The objectives of this study were (1) to determine the best conditions of chemical cleaning of a nanofiltration (NF) membrane (NF90) employed in the treatment of gold mining effluent, and (2) to investigate the effects of continuous exposure to mining effluent and an acid cleaning agent on NF characteristics. NF fouling was mainly due to inorganic species, and calcium sulfate (CaSO4·0.5H2O) was identified over membrane surface. Therefore, acid solutions were the most efficient in membrane cleaning, and ...

Despite being widely used, large differences in filtration-time and hydrodynamic conditions between bench- and large-scale membrane units make the scaling up of bench-scale results an issue. On the other hand, pilot tests allow obtaining more reliable information on hydrodynamic conditions, fouling rates, and cleaning methods. Hence, the aim of this study was to evaluate nanofiltration (NF) membrane fouling control strategies in an integrated ultrafiltration (UF)-NF pilot plant applied to the treatment ...

Acid mine drainage (AMD) is an effluent characterized by low pH and high concentrations of sulfate, metals, and metalloids. AMD treatment by membrane separation processes (MSP), specifically nanofiltration (NF) and reverse osmosis (RO) is particularly interesting; as these processes can retain divalent ions efficiently to produce high quality permeate for industrial reuse. This study aimed to evaluate the main operational conditions of the gold AMD treatment by MSP, and conduct a preliminary capital ...

Abstract Plasmodium vivax invasion into human reticulocytes is a complex process. The Duffy binding protein (DBP) dimerization with its cognate receptor is vital for junction formation in the invasion process. Due to its functional importance, DBP is considered a prime vaccine candidate, but variation in B-cell epitopes at the dimer interface of DBP leads to induction of strain-limited immunity. We believe that the polymorphic residues tend to divert immune responses away from functionally conserved ...

This study aimed to evaluate the effect of feed pH (2.2 - original effluent pH – up to 6.0) and temperature (20 up to 40°C) on the performance of integrated ultrafiltration (UF) and nanofiltration (NF) applied to gold mining effluent. pH increase led to a significant decrease in UF permeate flux. NF showed high retention efficiencies of ions when temperature was below 30°C. Retention of high-valence counter-ions to balance the charge of retained co-ions seemed to be the strongest NF mechanisms. Process ...
