Monte Carlo dosimetry of a realistic multicellular model of follicular lymphoma in a context of radioimmunotherapy
(2020)
Purpose
Small-scale dosimetry studies generally consider an artificial environment where the tumors are spherical and the radionuclides are homogeneously biodistributed. However, tumor shapes are irregular and radiopharmaceutical ...
Rapid shift in microbial community structure in a neutral hydrothermal hot spring from Costa Rica
(2020)
In this work, we characterize the geochemistry and microbial community of Bajo las Peñas, a neutral (pH 6.5-7.4), hot spring (T = 62.0-68.0°C) located near Turrialba Volcano, Costa Rica. The microbiota at its two sources ...
Revealing a new region of gamma-ray emission in the vicinity of HESS J1825–137
(2019-02-17)
HESS J1825–137 is a bright very high-energy gamma-ray source that has been firmly established as a pulsar wind nebula (PWN), and one of the most extended gamma-ray objects within this category. The progenitor supernova ...
The influence of temperature and pH on bacterial community composition of microbial mats in hot springs from Costa Rica
(2019)
We used the 16S rRNA gene pyrosequencing approach to investigate the microbial diversity and community composition in several Costa Rican hot springs alongside the latitudinal axis of the country, with a range of temperatures ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...
The water striders (Hemiptera: Heteroptera: Gerridae) of Costa Rica: new species, checklist, and new records
(2018)
Brachymetra bernaldi Cordeiro, sp. nov. (Hemiptera: Heteroptera: Gerridae) from Heredia, Costa Rica, is herein described, illustrated, and compared with congeners. The new species resembles B. albinervus (Amyot & Serville, ...
Chapter 6: Founder variations in isolated populations
(2020)
Isolated populations, also called population isolates and genetic isolates, present several characteristic features that make them useful in the study of the genetic basis of both Mendelian and complex disorders. The ...
Moisture sources for Central America: Identification of moisture sources using a Lagrangian analysis technique
(2010-03)
We herein present an analysis of the sources of atmospheric moisture for Central America using a Lagrangian technique. The results of backward and forward moisture tracking analysis using the FLEXPART model has enabled the ...
Three new species of Gliocephalotrichum causing fruit rot on different hosts from Brazil
(2020-09-18)
The genus Gliocephalotrichum (Nectriaceae), originally described as a soil-borne fungus, has been associated with postharvest diseases, especially of tropical fruits. Taxonomic studies using both morphological and molecular ...
Messua sp. (Salticidae), the host spider of the polysphinctine Inbioia pivai (Ichneumonidae: Pimplinae)
(2019)
The koinobiont ectoparasitoids of spiders in the Polysphincta genus group are divided into two well-supported clades. Species in one clade parasitize spiders in the higher araneoid group, and the behaviour of these ...
