  • Dynamics of floodplain lakes in the Upper Amazon Basin during the late Holocene 
    Quintana-Cobo, Isabel; Moreira-Turcq, Patricia; Cordeiro, Renato C.; Aniceto, Keila; Crave, Alain; Fraizy, Pascal; Moreira, Luciane S.; de Aguiar Duarte Contrera, Julia Maria; Turcq, Bruno (Elsevier, 2018)
    To better understand the impact of channel migration processes and climate change on the depositional dynamics of floodplain lakes of the upper Amazon Basin during the late Holocene, we collected three sediment cores from ...
  • Evaluation of bleach-sedimentation for sterilising and concentrating Mycobacterium tuberculosis in sputum specimens 
    Chew, R.; Calderón, C.; Schumacher, S.G.; Sherman, J.M.; Caviedes, L.; Fuentes, P.; Coronel, J.; Valencia, T.; Hererra, B.; Zimic-Peralta, Mirko Juan; Huaroto, L.; Sabogal, I.; Escombe, A.R.; Gilman, Robert Hugh; Evans, Carlton Anthony William (BioMed Central, 2011)
    Background: Bleach-sedimentation may improve microscopy for diagnosing tuberculosis by sterilising sputum and concentrating Mycobacterium tuberculosis. We studied gravity bleach-sedimentation effects on safety, sensitivity, ...
  • Hiperendemicidad de fasciolosis y factores de riesgo en niños de edad escolar del distrito de Orurillo, Puno 
    Quispe, W.P.; Beltrán, M.F.; Vargas, N.M.; Cabanillas A., José; Sánchez, E.R.; Valderrama, A.P. (Facultad de Medicina Veterinaria. Universidad Nacional Mayor de San Marcos, 2021)
    The aim of this study was to determine the association of fasciolosis in school-age children with intestinal parasites, food consumption and animal husbandry. The research was analytical, prospective, cross-sectional, and ...
  • Late Holocene fluctuations of Quelccaya Ice Cap, Peru, registered by nearby lake sediments 
    Stroup, J.S.; Kelly, M.A.; Lowell, T.V.; Smith, C.A.; Beal, S.A.; Landis, J.D.; Tapia, P.M. (Wiley, 2015)
    Records of clastic sediment from lakes that receive glacial meltwater provide a means for inferring past glacial fluctuations. However, increased clastic sedimentation has been interpreted to indicate both glacial advance ...
  • Origin and implications of orbital-induced sedimentary cyclicity in Pliocene well-logs of the Western Mediterranean 
    Ochoa, Diana; Sierro, F. J.; Hilgen, F. J.; Cortina, A.; Lofi, J.; Kouwenhoven, T.; Flores, J. A. (Elsevier, 2018)
    The climatic origin of astronomically induced sedimentary cycles in the Mediterranean and adjacent areas during the late Neogene and Quaternary remains puzzling; as cycles have been linked to concomitant but seasonally ...
  • Soil-transmitted helminthiasis in children from a rural community taking part in a periodic deworming program in the Peruvian Amazon 
    Errea, Renato A.; Vasquez-Rios, George; Calderon, Maria L.; Siu, Diego; Duque, Kevin R.; Juarez, Luciana H.; Gallegos, Rodrigo; Uriol, Celene; Rondon, Claudia R.; Baca, Katia P.; Fabian, Rosario J.; Canales, Marco; Terashima, Angelica; Marcos, Luis A.; Samalvides Cuba, Frine (American Society of Tropical Medicine and Hygiene, 2019)
    Children in the Peruvian Amazon Basin are at risk of soil-transmitted helminths (STH) infections. This study aimed to determine the prevalence of STH infection in children from a rural Amazonian community of Peru and to ...
  • Strongyloides stercoralis Infection at Different Altitudes of the Cusco Region in Peru 
    Morales Fernández, María Luisa; Lopez, Martha; Ly, Priscilla; Anjum, Seher; Fernandez-Baca, Martha Vanessa; Valdivia-Rodriguez, Angela Maria; Mamani-Licona, Frecia Maribel; Baca-Turpo, Benicia; Farfan-Gonzales, Nedhy; Chaman-Illanes, Yeshica; Cabada, Miguel Mauricio (American Society of Tropical Medicine and Hygiene, 2019)
    Strongyloides stercoralis affects 30-100 million people worldwide. The burden is underestimated because of the paucity of studies, limited geographical areas surveyed, and poor quality of diagnostic tests. This study aimed ...
  • Sub-fossil diatoms from the Saloum Estuary, Senegal, West Africa: Floristic inventory and paleo-productivity evolution along the Ndangonkha core 
    Gueye, Adama; Fofana, Abdoul Kader; Badiane, Insa; Carré, Matthieu; Youm, Ibrahima; Sow, El Hadji (Elsevier, 2023)
    As part of our program to reconstruct the estuaries and lagoons history in Senegal and the diatom microflora inventory in Sene-Gambia, a 400 cm long core was taken at Ndangonkha in the Saloum Estuary, near Foundiougne. The ...
  • Tidally driven sulfidic conditions in Peruvian mangrove sediments 
    Perez, Alexander; Gutierrez Aguilar, Dimitri Alexey; Saldarriaga, Maritza S.; Sanders, Christian J. (Springer, 2018)
    The seasonal influence of tidal regimes on sulfidic conditions was studied in intertidal environments from a mangrove estuary in Northern Peru. Along two sampling stations, creek water and sediment cores were collected ...
