In vitro evidence that an aqueous extract of Centella asiatica modulates α-synuclein aggregation dynamics.
(2014-01-01)α-Synuclein aggregation is one of the major etiological factors implicated in Parkinson's disease (PD). The prevention of ggregation of α-synuclein is a potential therapeutic intervention for preventing PD. The discovery ... -
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 ... -
Vacuolar Targeting of Cry1Ac and its Effects on Expression and Stability in Tobacco.
(2014-07-01)Increasing heterologous expression of delta endotoxins of Bacillus thuringiensis in transgenic plants is being actively pursued as a means to increase their efficacy and to delay insect resistance. To examine if vacuoles ... -
Comparative study on anti-oxidant and anti-inflammatory activities of Caesalpinia crista and Centella asiatica leaf extracts
(2014-04-01)Background: Amyloidosis, oxidative stress and inflammation have been strongly implicated in neurodegenerative disorders like Alzheimer's disease. Traditionally, Caesalpinia crista and Centella asiatica leaf extracts are ... -
Estimates of global, regional, and national incidence, prevalence, and mortality of HIV, 1980–2015: the Global Burden of Disease Study 2015
(2016-08-01)Timely assessment of the burden of HIV/AIDS is essential for policy setting and programme evaluation. In this report from the Global Burden of Disease Study 2015 (GBD 2015), we provide national estimates of levels and ... -
New perspectives on oxidized genome damage and repair inhibition by pro-oxidant metals in neurological diseases
(2014-07-17)The primary cause (s) of neuronal death in most cases of neurodegenerative diseases, including Alzheimer’s and Parkinson’s disease, are still unknown. However, the association of certain etiological factors, eg, oxidative ... -
A review of therapeutic effects of mesenchymal stem cell secretions and induction of secretory modification by different culture methods
(2014-10-11)The mesenchymal stem cell (MSC) is being broadly studied in clinical trials. Contrary to the early paradigm of cell replacement and differentiation as a therapeutic mechanism of action, evidence is mounting that the ... -
American trypanosomiasis, or Chagas disease, in Panama: a chronological synopsis of ecological and epidemiological research
(2017-10-10)American trypanosomiasis, or Chagas disease, is a growing public health problem in Panama, and further forest degradation due to human population growth is expected to worsen the situation. Most people infected with the ... -
Maternal invasion history of Aedes aegypti and Aedes albopictus into the Isthmus of Panama: Implications for the control of emergent viral disease agents
(2018-03-26)Despite an increase in dengue outbreaks and the arrival of chikungunya and Zika disease in Panama, studies on the demographic history of the invasive Aedes mosquitoes that are the principle vectors of these diseases are ... -
Socioeconomic and demographic predictors of resident knowledge, attitude, and practice regarding arthropod-borne viruses in Panama
(2018-09-18)Background: We sought to identify if socioeconomic and demographic factors play a role in resident knowledge, attitude, and practice regarding Dengue, Chikungunya, and Zika in order to inform effective management procedures ... -
A systematic account of the genus Plagiostoma (Gnomoniaceae, Diaporthales) based on morphology, host-associations, and a four-gene phylogeny
(2014-05-27)Members of the genus Plagiostoma inhabit leaves, stems, twigs, and branches of woody and herbaceous plants predominantly in the temperate Northern Hemisphere. An account of all known species of Plagiostoma including ... -

Pervasive effects of a dominant foliar endophytic fungus on host genetic and phenotypic expression in a tropical tree
(2014-09-12)It is increasingly recognized that macro-organisms (corals, insects, plants, vertebrates) consist of both host tissues and multiple microbial symbionts that play essential roles in their host’s ecological and evolutionary ... -
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 ... -
Molecular validation of anthropophilic Phlebotominae sandflies (Diptera: Psychodidae) in Central Panama
(2019-08-15)Six Phlebotominae sand fly species are incriminated as biological vectors of human pathogens in Panama, but molecular corroboration is still needed. We aim at confirming the identity of Phlebotominae species documented as ... -
The impact of biological invasion and genomic local adaptation on the geographical distribution of Aedes aegypti in Panama
(2019-01-01)Local adaptation is an important consideration when predicting arthropod-borne disease risk because it can impact on vector population fitness and persistence. However, the extent that vector populations are adapted to ... -
Mitogenomics of Central American weakly-electric fishes
