(2011-06-04)
Microfungi in the Gnomoniaceae (Diaporthales, Ascomycetes) comprise species commonly reported as pathogens and endophytes on trees and herbaceous hosts primarily from temperate forests of North America, Europe, and Japan. ...
New species, phylogeny, host-associations and geographic distribution of genus Cryptosporella (Gnomoniaceae, Diaporthales)
(2011-03-01)
The phylogeny of Cryptosporella is revised to include recently discovered species. Eight species new to science are described and two new combinations are proposed, raising the total number of species accepted in Cryptosporella ...
Amplified fragment length polymorphisms reveals high intraspecific variability in field isolates of Leishmania panamensis
(2011-04-01)
Leishmania parasites cause leishmaniasis, a potentially deadly re-emergent disease that affects millions throughout the world. In Panama, the disease is showing an increasing trend, with estimates of thousands of new cases ...
DNA Repair Mechanisms as Drug Targets in Prokaryotes
(2011-07-01)
Nowadays, a great amount of pathogenic bacteria has been identified such as Mycobacterium sp. and Helicobacter pylori and have become a serious health problem around the world. These bacteria have developed several DNA ...
Chemical Constituents of the New Endophytic Fungus Mycosphaerella sp. nov. and Their Anti-Parasitic Activity
(2011-06-15)
Chemical investigation of a new endophytic fungus, Mycosphaerella sp. nov. strain F2140 associated with the foliage of the plant Psychotria horizontalis (Rubiaceae) in Panama, resulted in the isolation of cercosporin (1) ...
Comparison of the in vitro invasive capabilities of Plasmodium falciparum schizonts isolated by Percoll gradient or using magnetic based separation
(2011-04-18)
Background: Percoll gradient centrifugation is often used for synchronization, enrichment, or isolation of a particular stage of Plasmodium falciparum. However, Percoll, a hyperosmotic agent, may have harmful effects on ...
Screening and evaluation of antiparasitic and in vitro anticancer activities of Panamanian endophytic fungi
(2011-06-14)
Parasitic infections are major causes of human chronic diseases in most countries of the tropics. The parasites include protozoa and helminths, infect billions of people, and the resulting diseases cause debilitating ...
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 ...
Automated Synchronization of P. falciparum using a Temperature Cycling Incubator
(2011-04)
As malaria keeps affecting millions of lives every year, research based in culture of Plasmodium falciparum in vitro needs to be efficient and accurate. The development of better techniques and methodologies for the growth ...
