Synthesis of Dihydroindolo[2,3-c]carbazole as Potential Telomerase Inhibitor
(Journal of Heterocyclic Chemistry vol.53 no.3 762-766 2015, 2015-05-27)
The dictyodendrins A-E were the first marine natural products that show inhibition of telomerase. A versatile and convergent route was described for the synthesis of derivatives of these pyrrolo[2,3-c]carbazole alkaloids ...
The manufacture and properties of oil palm and pineapple leaf fiberboard panels
(WIT Transactions on Ecology and the Environment, 2014)
Particleboards were manufactured from oil palm fruit, the oil palm mesocarp fiber of Elaeis guineensis, the leaves of pineapple (Ananas comosus) and the sawdust from three fast-growing species of trees (Gmelina arborea, ...
Variación del oxígeno disuelto en el Río Burío-Quebrada Seca, Heredia, Costa Rica, en el periodo 2005 - 2010
(2013-08-22)
Las aguas superficiales constituyen una de las fuentes más importantes de agua dulce, sin embargo, una gran cantidad de ríos ubicados en zonas urbanas, están siendo utilizados como medios para la eliminación de residuos ...
Spatial and Temporal Variation of Stable Isotopes in Precipitation across Costa Rica: An Analysis of Historic GNIP Records
(2013-11-27)
The location of Costa Rica on the Central American Isthmus creates unique microclimate systems that receive moisture inputs directly from the Caribbean Sea and the Pacific Ocean. In Costa Rica, stable isotope monitoring ...
Biogardens as constructed wetlands in tropical climate: A case study in the Central Pacific Coast of Costa Rica
(Elsevier, 2019-03-25)
In Costa Rica, <10% of wastewater is treated before its discharge. This generates a significant impact on the environment, public health, and tourism industry, which is one of the country's main economic activities. ...
Chemical and functional characterization of antimicrobial metabolites isolated from ascidian Rhopalaea Birkelandi
(Universidad Nacional (Costa Rica), 2011-12)
Marine ecosystems have a very large diversity of resources, most of them still partially unknown, and a
few others exploited for development of new industrial and toxicological products. The objective of this
investigation ...
Groundwater recharge mechanisms inferred from isoscapes in a complex tropical mountainous region
(AGU Publications, 2016-05-23)
Stable isotope variations and groundwater recharge mechanisms remain poorly understood across the tropics, particularly in Central America. Here stable isotopes (δ18O and δ2H) in groundwater, surface water, and rainfall ...
Irbesartan desmotropes: Solid-state characterization, thermodynamic study and dissolution properties
(Xi'an Jiaotong University, 2019-07-10)
Irbesartan (IBS) is a tetrazole derivative and antihypertensive drug that has two interconvertible structures, 1H- and 2H-tautomers. The difference between them lies in the protonation of the tetrazole ring. In the ...
DOC Transport and Export in a Dynamic Tropical Catchment
(American Geophysical Union, 2019)
Abstract Dissolved organic carbon (DOC) transport and export from headwater forests into freshwaters in highly dynamic tropical catchments are still understudied. Here we present a DOC analysis (2017) in a
pristine and ...
Tracer hydrology in a hydrometric data-limited and complex tropical mountainous region: the case of the Central American Isthmus
(European Geosciences Union, 2019)
Numerous socio-economic activities are dependent on the seasonal rainfall and groundwater recharge cycle across the Central American Isthmus. Demographic growth and unregulated land use changes resulted in extensive surface ...
