ECOLOGICAL IMPLICATIONS OF ANTI-PATHOGEN EFFECTS OF TROPICAL FUNGAL ENDOPHYTES AND MYCORRHIZAE
(2007-03-01)We discuss studies of foliar endophytic fungi (FEE) and arbuscular mycorrhizal fungi (AMF) associated with Theobroma cacao in Panama. Direct, experimentally controlled comparisons of endophyte free (E—) and endophyte ... -
Effect of Post Weld Heat Treatments on the Elevated Temperature Mechanical Properties of Ti6Al4V Friction Welds
(2018-02-09)The {\alpha}+\b {eta} titanium alloy (Ti6Al4V) has been successfully joined using rotary friction welding. To investigate the influence of post weld heat treatments on the microstructure and mechanical properties of the ... -
The effects of combined micron-/submicron-scale surface roughness and nanoscale features on cell proliferation and differentiation
(2011-02-08)Titanium (Ti) osseointegration is critical for the success of dental and orthopedic implants. Previous studies have shown that surface roughness at the micro- and submicro-scales promotes osseointegration by enhancing ... -
The effects of impaired cerebral circulation on Alzheimer's disease pathology: evidence from animal studies.
(2014-01-01)Persistent systemic hypoxia, a direct consequence of alterations in vascular function, can compromise the brain by increasing the risk of developing dementias such as Alzheimer’s disease (AD). Vascular contributions to ... -
Effects of structural properties of electrospun TiO2 nanofiber meshes on their osteogenic potential
(2011-10-31)Ideal outcomes in the field of tissue engineering and regenerative medicine involve biomaterials that can enhance cell differentiation and production of local factors for natural tissue regeneration without the use of ... -
Electrical Polarization of Titanium Surfacesfor the Enhancement of Osteoblast Differentiation
(2013-08-29)Electrical stimulation has been used clinically to promote bone regeneration in cases of fractures with delayed union or nonunion, with several in vitro and in vivo reports suggesting its beneficial effects on bone formation. ... -
Endomelanconiopsis, a new anamorph genus in the Botryosphaeriaceae
(2014-05-20)A new lineage is discovered within the Botryosphaeriaceae (Ascomycetes, Dothideomycetes, incertae sedis). Consistent with current practice of providing generic names for independent lineages, this lineage is described as ... -
Environmental Conditions May Shape the Patterns of Genomic Variations in Leishmania panamensis
(2019-10-24)Due to the absence of transcriptional regulation of gene expression in Leishmania parasites, it is now well accepted that several forms of genomic variations modulate the levels of critical proteins through changes in gene ... -

Enzootic Arbovirus Surveillance in Forest Habitat and Phylogenetic Characterization of Novel Isolates of Gamboa Virus in Panama
(2016-04-06)Landscape changes occurring in Panama, a country whose geographic location and climate have historically supported arbovirus transmission, prompted the hypothesis that arbovirus prevalence increases with degradation of ... -
Epidemic and Non-Epidemic Hot Spots of Malaria Transmission Occur in Indigenous Comarcas of Panama
(2016-05-16)From 2002–2005, Panama experienced a malaria epidemic that has been associated with El Niño Southern Oscillation weather patterns, decreased funding for malaria control, and landscape modification. Case numbers quickly ... -
Erratum to: Theobroma cacao L. pathogenesis-related gene tandem array members show diverse expression dynamics in response to pathogen colonization
(2016-09-07)The original version of the manuscript [1] contained an incorrectly named Criollo gene ID on chromosome 1 in the first sentence, under the subheading “Organization of PR gene families into tandem arrays”. The second gene ... -
