Giardiasis is considered the most common intestinal parasitic disease in humans worldwide. In Cuba, this infection has particularly a strong clinical impact on the child population. Giardia duodenalis is a highly diverse protozoan, which comprises a complex of eight morphologically identical genetic assemblages, further divided into sub-assemblages. The present study used triose phosphate isomerase ( tpi ) and small-subunit ribosomal RNA (SSU rRNA) genes as genetic markers for the identification of G. duodenalis assemblages and sub-assemblages in correlation with clinical and epidemiological data in children attended at the Paediatric Hospital "William Soler" and at Pedro Kouri Institute, between 2015 and 2016...

Ageing on lees (AOL) is a technique that increases volatile compounds, promotes colour stability, improves mouthfeel and reduces astringency in red wines. The main drawback is that it is a slow process. Several months are necessary to obtain perceptible effects in wines. Different authors have studied the application of new techniques to accelerate the AOL process. Ultrasound (US) has been used to improve different food industry processes; it could be interesting to accelerate the yeast autolysis during AOL...

We have performed a genome-wide ENU mutagenesis screen in mice to identify novel genes or alleles that regulate erythropoiesis. Here we describe a recessive mouse strain, called RBC19, harbouring a point mutation within the housekeeping gene, Tpi1 , which encodes for the glycolysis enzyme, triosephosphate isomerase (TPI). A serine in place of a phenylalanine at amino acid 57 severely diminishes enzyme activity in red cells and other tissues, resulting in a macrocytic haemolytic phenotype in homozygous mice that closely resembles human TPI deficiency...

Triosephosphate isomerase (TPI), the glycolytic enzyme that catalyzes the isomerization of dihydroxyacetone phosphate (DHAP) to glyceraldehyde-3-phosphate (G3P), has been frequently identified as a target of S-nitrosylation by proteomic studies. However, the effect of S-nitrosylation on its activity has only been explored in plants and algae. Here, we describe the in vitro S-nitrosylation of human TPI (hTPI), and the effect of the modification on its enzymatic parameters. NO-incorporation into the enzyme cysteine residues occurred by a time-dependent S-transnitrosylation from both, S-nitrosocysteine (CySNO) and S-nitrosoglutathione (GSNO), with CySNO being the more efficient NO-donor...
