Expression analysis of two SOMATIC EMBRYOGENESIS RECEPTOR KINASE (SERK) genes during in vitro morphogenesis in Spanish cedar (Cedrela odorata L.)
(2018-11-08)Somatic embryogenesis (SE) is one of the most important steps during regeneration, but the molecular mechanism of SE remains unclear for Cedrela odorata. SOMATIC EMBRYOGENESIS RECEPTOR-LIKE KINASE (SERK) is one of the genes ... -
Expression of Olig2, Nestin, NogoA and AQP4 have no impact on overall survival in IDH- wildtype glioblastoma
(2020)Despite many years of research efforts and clinical trials the prognosis of patients diagnosed with glioblastoma remains very poor. The oligodendrocyte transcription factor 2 (Olig2) was identified as a marker for glioma ... -
Expression of the rice hoja blanca virus (RHBV) non-structural protein 3 (NS3) in Escherichia coli and its in situ localization in RHBV-infected rice tissues
(Universidad de Costa Rica, 2004)The non-structural NS3 protein gene from the rice hoja blanca virus (RHBV) was fused to the glutathione- S-transferase carboxilic end and expressed in Escherichia coli strain JM83. Large quantities of fusion protein were ... -

Extension of torsors and prime to p fundamental group scheme
(2020)Let R be a discrete valuation ring with fraction field K. Let X be a proper and faithfully flat R-scheme, endowed with a section x∈X(R), with connected and reduced generic fibre Xη. Let f:Y→Xη be a finite Nori-reduced ... -
Extensive Mucocutaneous Histiocytic Sarcoma raised from an Acute B Lymphocytic Leukemia: A Case Report at Hospital Mexico, Costa Rica
(2017-07)Histiocytic sarcomas are rare neoplasms with poor prognosis originating from histiocytic or dendritic cell clones and associated with haematological malignancies such as acute or chronic leukemias and lymphomas. We describe ... -
Extent and socio-economic significance of slope-instability on the Island of Hispaniola (Haiti and Dominican Republic)
(1995)On the island of Hispaniola, unstable slopes are common phenomena, especially those associated with intensive soil erosion and landslides. In Haiti, soil erosion is extreme and has contributed to the problems of food supply ... -
External Morphology of Tagosodes orizicolus (Homoptera: Delphacidae) Revealed by Scanning Electron Microscopy
(2001)A comprehensive analysis of the ultrastructure of the delphacid rice pest Tagosodes orizicolus (Muir) was undertaken using scanning electron microscopy to resolve taxonomic problems in the distinction of females and nymphs ... -
