High GUD incidence in the early 20 century created a particularly permissive time window for the origin and initial spread of epidemic HIV strains

  • Autores: de Sousa JD, Lemey P, Müller V, Vandamme AM
  • Ano de Publicação: 2010
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=High+GUD+Incidence+in+the+Early+20(th)+Century+Created+a+Particularly+Permissive+Time+Window+for+the+Origin+and+Initial+Spread+of+Epidemic+HIV+Strains

The processes that permitted a few SIV strains to emerge epidemically as HIV groups remain elusive. Paradigmatic theories propose factors that may have facilitated adaptation to the human host (e.g., unsafe injections), none of which provide a coherent explanation for the timing, geographical origin, and scarcity of epidemic HIV strains.

Visualisation of Leishmania donovani fluorescent hybrids during early stage development in the sand fly vector.

  • Autores: Lewis MD, Mauricio I, Miles MA, Sadlova J, Seblova V, Volf P, Yeo M
  • Ano de Publicação: 2011
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Visualisation+of+Leishmania+donovani+fluorescent+hybrids+during+early+stage+development+in+the+sand+fly+vector

BACKGROUND:
The Leishmania protozoan parasites cause devastating human diseases. Leishmania have been considered to replicate clonally, without genetic exchange. However, an accumulation of evidence indicates that there are inter-specific and intra-specific hybrids among natural populations.

Origin and Epidemiological History of HIV-1 CRF14_BG

  • Autores: Abecasis AB, Barroso H, Bártolo I, Borrego P, Camacho R, Gomes P, McCutchan F, Taveira N
  • Ano de Publicação: 2011
  • Journal: PLoS One
  • Link: https://apps.webofknowledge.com/full_record.do?product=UA&search_mode=GeneralSearch&qid=26&SID=P2WA5hwy5j35Sqjoq2z&page=1&doc=1

Background: CRF14_BG isolates, originally found in Spain, are characterized by CXCR4 tropism and rapid disease progression. This study aimed to identify the origin of CRF14_BG and reconstruct its epidemiological history based on new isolates from Portugal.

Background: Unlike in HIV-1 infection, the majority of HIV-2 patients produce broadly reactive neutralizing antibodies, control viral replication and survive as elite controllers.

Development of mathematical models for the analysis of hepatitis delta virus viral dynamics

  • Autores: Cunha C, de Sousa BC
  • Ano de Publicação: 2010
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/20862328

BACKGROUND:
Mathematical models have shown to be extremely helpful in understanding the dynamics of different virus diseases, including hepatitis B. Hepatitis D virus (HDV) is a satellite virus of the hepatitis B virus (HBV).

Bayesian Latent Class Models in malaria diagnosis.

  • Autores: de Oliveira MR, Do Rosário V, Gonçalves L, Lee PW, Shaio MF, Subtil A
  • Ano de Publicação: 2012
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/22844405

AIMS:
The main focus of this study is to illustrate the importance of the statistical analysis in the evaluation of the accuracy of malaria diagnostic tests, without admitting a reference test, exploring a dataset (n=3317) collected in São Tomé and Príncipe.

Is prnt a pseudogene? Identification of ram Prt in testis and ejaculated spermatozoa.

  • Autores: Baptista MC, Barbas JP, Cantante C, Domingos A, Fontes CA, Gonçalves J, Horta AE, Marques CC, Mesquita P, Pereira RM, Pimenta J, Prates JA, Santos A, Santos P, Viegas A
  • Ano de Publicação: 2012
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Is+prnt+a+Pseudogene%3F+Identification+of+Ram+Prt+in+Testis+and+Ejaculated+Spermatozoa.

A hallmark of prion diseases or transmissible spongiform encephalopaties is the conversion of the cellular prion protein (PrP(C)), expressed by the prion gene (prnp), into an abnormally folded isoform (PrP(Sc)) with amyloid-like features that causes scrapie in sheep among other diseases. prnp together with prnd (which encodes a prion-like protein designated as Doppel), and prnt (that encodes the prion protein testis specific–Prt) with sprn (shadow of prion protein gene, that encodes Shadoo or Sho) genes, constitute the “prion gene complex”.

Trypanosoma cruzi IV causing outbreaks of acute Chagas disease and infections by different haplotypes in the Western Brazilian Amazonia.

  • Autores: Barbosa Md, Borges L, de Sá AR, Gomes ML, Guerra JA, Magalhaes LK, Monteiro WM, Pires I, Silveira H, Toledo MJ
  • Ano de Publicação: 2012
  • Journal: PLoS One
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Trypanosoma+cruzi+IV+Causing+Outbreaks+of+Acute+Chagas+Disease+and+Infections+by+Different+Haplotypes+in+the+Western+Brazilian+Amazonia.

BACKGROUND:
Chagas disease is an emergent tropical disease in the Brazilian Amazon Region, with an increasing number of cases in recent decades. In this region, the sylvatic cycle of Trypanosoma cruzi transmission, which constitutes a reservoir of parasites that might be associated with specific molecular, epidemiological and clinical traits, has been little explored. The objective of this work is to genetically characterize stocks of T. cruzi from human cases, triatomines and reservoir mammals in the State of Amazonas, in the Western Brazilian Amazon.

Clinical Evaluation of Rega 8: An Updated Genotypic Interpretation System That Significantly Predicts HIV-Therapy Response

  • Autores: Beheydt G, Camacho R, Clotet B, De Luca A, Geretti AM, Grossman Z, Imbrechts S, Kaiser R, Libin P, Prosperi M, Schmit JC, Sönnerborg A, Torti C, Van Laethem K, Van Wijngaerden E, Vandamme AM, Vercauteren J, Zazzi M
  • Ano de Publicação: 2013
  • Journal: PLoS One
  • Link: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0061436

Clinically evaluating genotypic interpretation systems is essential to provide optimal guidance in designing potent individualized HIV-regimens. This study aimed at investigating the ability of the latest Rega algorithm to predict virological response on a short and longer period.
