Information on the known species diversity of the non-marine ostracods in Venezuela is compiled from the available literature. The review resulted in 34 species and two varieties, belonging to the superfamilies Cypridoidea and Cytheroidea. Of these, the presence of one species should be confirmed for the country. Furthermore, eight taxonomic entiti...
The incorporation of quantum dots in display technology has fueled a renewed interest in InP-based quantum dots, but difficulty controlling the Zn chemistry during shelling has stymied thick, even ZnSe shell growth. The characteristic uneven, lobed morphology of Zn-based shells is difficult to assess qualitatively and measure through traditional me...
Citation: Pardo, M.J.; Scott-Frías, J.; Soto, L.M.; Stamou, G.; Michaloudi, E.; Torres, R.; González, E.; López, C. Rotifers Abstract: Rotifers represent an important component of freshwater zooplankton. The high richness of taxa, particularly in littoral macrophyte zones of water bodies in tropical and subtropical flood-prone areas, is a repeatedl...
Venezuela has a high diversity of freshwater habitats distributed in seven hydrographic basins. The great variety of conditions that influence them has allowed the development of extensive zooplankton assemblages and a high diversity of taxa. More than 400 zooplankton taxa have been taxonomically recognized within the groups of protozoa, rotifers (...

The serotonin transporter (SERT) is the primary target for selective serotonin reuptake inhibitor (SSRI) antidepressants that are thought to exert their therapeutic effects by increasing the synaptic concentration of serotonin. Consequently, probes that can be utilized to study cellular trafficking of SERT are valuable research tools. We have devel...
The role of lateral mobility and nanodomain organization of G protein-coupled receptors in modulating subcellular signaling has been under increasing scrutiny. Investigation of D2 dopamine receptor diffusion dynamics is of particular interest, as these receptors have been linked to altered neurotransmission in affective disorders and represent the...
D2 dopamine receptors (DRD2s) belong to a family of G protein-coupled receptors that modulate synaptic dopaminergic tone via regulation of dopamine synthesis, storage, and synaptic release. DRD2s are the primary target for traditional antipsychotic medications; dysfunctional DRD2 signaling has been linked to major depressive disorder, attention-def...
Plankton samples from a small temporal pond in Puebloviejo, Magdalena Department, yielded two species of the genus Cletocamptus Schmankewitsch 1875: Cletocamptus samariensis sp. nov and Cletocamptus nudus Gómez,2005. The new species is closely related to C. schmidti Mielke, 2000 and C. nudus Gómez, 2005 based on the armature formula of P1-P4, but c...
RESUMEN Los humedales constituyen ecosistemas importantes para el plancton como fuentes de alimentación, refugios y sitios reproductivos. Se realizan estudios planctónicos en humedales de la península de Paria, Mantecal y lagunas de inundación del río Orinoco, con el fin de conocer las variaciones de sus abundancias en función de la vegetación acuá...
Los humedales herbáceos se encuentran entre los ecosistemas más productivos del planeta debido a procesos biogeoquímicos particulares originados por plantas emergentes, lo que se traduce en magnificación de la producción de biomasa viva y deposición continua de materia orgánica muerta. Se hizo un experimento de campo en un humedal herbáceo de la re...
