A review on the wettability of dental implant surfaces I: Theoretical and experimental aspects
(2014-02-28)The surface wettability of biomaterials determines the biological cascade of events at the biomaterial/ host interface. Wettability is modulated by surface characteristics, such as surface chemistry and surface topography. ... -
Tuberculosis remains a challenge despite economic growth in Panama
(2014-03-01)Tuberculosis (TB) is a disease associated with inequality, and wise investment of economic resources is considered critical to its control. Panama has recently secured its status as an upper-middle-income country with ... -
Chemical and bioactive natural products from Microthyriaceae sp., an endophytic fungus from a tropical grass
(2014-03-04)In screening for natural products with antiparasitic activity, an endophytic fungus, strain F2611, isolated from above-ground tissue of the tropical grass Paspalum conjugatum (Poaceae) in Panama, was chosen for bioactive ... -

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 ... -
A review on the wettability of dental implant surfaces II: Biological and clinical aspects
(2014-04-05)Dental and orthopedic implants have been under continuous advancement to improve their interactions with bone and ensure a successful outcome for patients. Surface characteristics such as surface topography and surface ... -
Implant osseointegration and the role of microroughness and nanostructures: Lessons for spine implants
(2014-04-08)The use of spinal implants for spine fusion has been steadily increasing to avoid the risks of complications and donor site morbidity involved when using autologous bone. A variety of fusion cages are clinically available, ... -
Role of a2b1 integrins in mediating cell shape on microtextured titanium surfaces
(2014-05-07)Surface microroughness plays an important role in determining osteoblast behavior on titanium. Previous studies have shown that osteoblast differentiation on microtextured titanium substrates is dependent on alpha-2 beta-1 ... -
American Cutaneous Leishmaniasis in Panama: a historical review of entomological studies on anthropophilic Lutzomyia sand fly species
(2014-05-11)We review existing information on the epidemiology of American Cutaneous Leishmaniasis (ACL) in Panama, with emphasis on the bionomics of anthropophilic Lutzomyia sand fly species. Evidence from Panamanian studies suggests ... -
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 ... -
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 ... -
Storage in ultra-low-temperature decreases the levels of IgM anticardiolipin antibody in serum samples from tuberculosis patients
(2014-06-01)The evaluation of novel tuberculosis (TB) biomarkers relies on analysis of previously stored sample sets. We aimed to determine the effect of storage temperature on serum IgM anticardiolipin antibody levels in samples from ... -
Evaluation of anti-Bothrops asper venom activity of ethanolic extract of Brownea rosademonte leaves
(2014-06-20)Significant inhibition of the coagulant and hemorrhagic effects of Bothrops asper venom was demonstrated by ethanolic extract prepared from the leaves of Brownea rosademonte. In vitro experiments preincubating 5.5 mg of ... -
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 ... -
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, e.g., oxidative ... -
