The pathogenic nature of E. histolytica was first reported by Fedor A. Lösch in 1875, [1] but it was not given its Latin name until Fritz Schaudinn described it in 1903. E. histolytica, as its name suggests (histo–lytic = tissue destroying), is pathogenic; infection can be asymptomatic, or it can lead to amoebic dysentery or amoebic liver ...
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
While these journals still did not receive an impact factor until the next year, they did contribute citations to the calculation of other journals' impact factors. [ 4 ] [ 5 ] In July 2022, Clarivate announced that journals in the ESCI obtain an impact factor effective from JCR Year 2022 first released in June 2023.
The two most common manifestations of E histolytica include colitis (bloody stool with mucus, abdominal pain, and/or diarrhea), and discovery of a liver abscess on imaging. [2] Liver abscesses commonly present as right upper quadrant abdominal pain and fever, with worsening features associated with abscess rupture.
The values for Nature journals lie well above the expected ca. 1:1 linear dependence because those journals contain a significant fraction of editorials. CiteScore was designed to compete with the two-year JCR impact factor, which is currently the most widely used journal metric. [7] [8] Their main differences are as follows: [9]
Amoebic brain abscess is an affliction caused by the anaerobic parasitic protist Entamoeba histolytica.It is extremely rare; the first case being reported in 1849. [2] Brain abscesses resulting from Entamoeba histolytica are difficult to diagnose and very few case reports suggest complete recovery even after the administration of appropriate treatment regimen.
The purified Dmc1 from E. histolytica forms presynaptic filaments and catalyzes ATP-dependent homologous DNA pairing and DNA strand exchange over at least several thousand base pairs. [12] The DNA pairing and strand exchange reactions are enhanced by the eukaryotic meiosis-specific recombination accessory factor (heterodimer) Hop2-Mnd1. [ 12 ]
The choices being Entamoeba moshkovskii, Entamoeba histolytica, or Entamoeba dispar. These three choices are, in the view of the microscope, "indistinguishable". [1] This is the point where a doctor makes the call for what is most common (Entamoeba histolytica) or something more rare (Entamoeba mushkovskii).
