background: in this paper, paleoparasitological findings from rodent excrements ob-tained from chehrabad salt mine archeological site located in northwest of iran are demonstrated and discussed. methods : chehrabad salt mine archeological site located in northwest of iran, dated to the achaemenid (mid 1st mill. bce) and to sassanid (3rd cent. - 7th cent. ce) period, is a unique study area to in...

background: rodents play an important role as reservoir of some pathogens, and the host of some ectoparasites as well. these ectoparasites can transmit rodents’ pathogens to human or animals. the aim of this study was to assess the distribution and infestation load of ectoparasites on rodents in meshkin-shahr district, northwestern iran . method: rodents were captured using baited live traps in...

b a ckground: zoonotic cutaneous leishmaniasis (zcl) is endemic in many parts of iran. recently its incidence isconsiderable in different parts of jahrom district, in fars province, southern iran. the aims of our study were to in- vestigate the prevalence of leishmania infection, and identify and characterize the   leishmania species present, among the rodents by molecular methods in a new ende...

Progress in paleoanthropology is impeded when new fossil materials are published but unavailable for comparative study, as is too often the case. In this commentary, we review the stages of description and analysis that new fossils must undergo and conclude that it is disingenuous to argue that fossils have not been properly "published" when descriptions and new names formulated in accordance w...

BACKGROUND The 2009 influenza A(H1N1) pandemic has generated thousands of articles and news items. However, finding relevant scientific articles in such rapidly developing health crises is a major challenge which, in turn, can affect decision-makers' ability to utilise up-to-date findings and ultimately shape public health interventions. This study set out to show the impact that the inconsiste...
