Red blood cells derived from peripheral blood and bone marrow CD34+ human haematopoietic stem cells are permissive to Plasmodium parasites infection

The production of fully functional human red cells in vitro from haematopoietic stem cells (hHSCs) has been successfully achieved. Recently, the use of hHSCs from cord blood represented a major improvement to develop the continuous culture system for Plasmodium vivax. Here, we demonstrated that CD34+hHSCs from peripheral blood and bone marrow can be expanded and differentiated to reticulocytes using a novel stromal cell. Moreover, these reticulocytes and mature red blood cells express surface markers for entrance of malaria parasites contain adult haemoglobin and are also permissive to invasion by P. vivax and Plasmodium falciparum parasites.

El implante de condrocitos autólogos en la red sanitaria pública de Andalucía. Resultados tras 6 años de circuito asistencial.

Objective: To asses the results of Autologous Chondrocyte Implantation (ACI) whith periosteal patch and To propagate the care circuits existing about in Andalusia. Material and Methods: From its of ficial licence in 2005, the tissue bank and the Virgen de la Victoria Hospital from Málaga, performed the ACI in the Andalusian public health system. 16 patients has been operated between 2006-2013, whith medium follow-up 47,6 months (6 months-6 years), from public hos- pitals throughout Andalucia, managed by hospital admission source and destination. Physiologically younger patients were selected (<50 años), with singles, > 2cm2 symptomatics chondral lesions, in stables and well aligned knees. ACI was used as res- cue procedure after microfracture ́s failure except osteochondritis dissecans. To assess the results the Concinnati score and the Short Form 36 (SF-36) score were used. A descriptive analysis was performed and non-parametric tests were used to establish correlations and compare results. Results: In 15 patients with more than one year of follow-up: 14 men(87.5%) and 2women (14.5%), medium age 28.2 years old (min 17 max 43), the lesion was located into de femoral condyle, mostly in the internal one (81,2%) with medium size 2,7cm2(2-4,2). We founded significant improvement (p<0,001), both daily activities ( 89,3% preop. limitatión - 9% postop), as in the sports (90,2% preop limitatión - 38% postop) and the exploration of the knee (67,7% hpatological findings preop- 13,3%postop). The SF-36 score improved in all categories, over all in mental health (p> 0,01). The patient satisfaction was high or very high in 12 of the 15 patients ( 80%), and low in 3 patients. Conclusions: ACI improve quality of life and knee function in femoral condyle chondral lesions. The case ́s selection and the collaboration with Tissue Bank, allows us to create care circuits for treatment of patients from other provinces in the Public Sanitary Health System in Andalucia. It is necessary to increase the experience with this type of therapy, consolidating multicenter workgroups that provide strength to the conclusions.

Getting ready for malaria elimination: a check list of critical issues to consider

In recent years, a renewed interest in malaria elimination and eradication has emerged and seems to be rooting in the minds of the scientific community, public health specialists, funding bodies, policy makers and politicians. Malaria eradication will certainly benefit from improved and innovative tools; notwithstanding novel knowledge in fields ranging from basic science to mathematical modelling and health systems research. However, the elimination of malaria also encompasses a broad range of essential aspects that countries and other actors need to consider when thinking of embarking on such an adventure, including the implementation of innovative strategies, the ability to incorporate the most up-to-date evidence into policy, the integration of malaria into the broader health agenda, the strengthening of surveillance and health systems, capacity building, funding, advocacy and, very importantly, research. While in some cases this enthusiasm is clearly justified, some countries are still a long way from realistically advancing towards elimination. This paper attempts to provide guidance on all the necessary issues that should be considered when initiating a malaria elimination program.

Antibody recognition of Plasmodium falciparum infected red blood cells by symptomatic and asymptomatic individuals in the Brazilian Amazon

In the Amazon Region, there is a virtual absence of severe malaria and few fatal cases of naturally occurring Plasmodium falciparum infections; this presents an intriguing and underexplored area of research. In addition to the rapid access of infected persons to effective treatment, one cause of this phenomenon might be the recognition of cytoadherent variant proteins on the infected red blood cell (IRBC) surface, including the var gene encoded P. falciparum erythrocyte membrane protein 1. In order to establish a link between cytoadherence, IRBC surface antibody recognition and the presence or absence of malaria symptoms, we phenotype-selected four Amazonian P. falciparum isolates and the laboratory strain 3D7 for their cytoadherence to CD36 and ICAM1 expressed on CHO cells. We then mapped the dominantly expressed var transcripts and tested whether antibodies from symptomatic or asymptomatic infections showed a differential recognition of the IRBC surface. As controls, the 3D7 lineages expressing severe disease-associated phenotypes were used. We showed that there was no profound difference between the frequency and intensity of antibody recognition of the IRBC-exposed P. falciparum proteins in symptomatic vs. asymptomatic infections. The 3D7 lineages, which expressed severe malaria-associated phenotypes, were strongly recognised by most, but not all plasmas, meaning that the recognition of these phenotypes is frequent in asymptomatic carriers, but is not necessarily a prerequisite to staying free of symptoms.

The list of the chromosome races of the common shrew Sorex araneus (updated 2002)

In 1996 the International Sorex araneus Cytogenetics Committee (ISACC) published a comprehensive list of 50 chromosome races of the common shrew Sorex araneus (lima et al. 1996). Since that time twenty one new races have been described and three races have been removed from the list. The present list summarises the data about races described since the 1996 publication. The rules introduced by Searle et al. (1991) and Hausser et al. (1994) were followed in the compilation of the list. It can be considered a reference for further studies of evolutionary relationships between the chromosome races of Sorex araneus. A summary table of all the 68 known races, arranged alphabetically according to their names, is given.
