Recently encoded information can be lost in the presence of new information, a process called 'retrograde interference'. Retrograde interference has been extensively described for more than a century; however, little is known about its underlying mechanisms. Different approaches agree on the need of the synthesis of plasticity related proteins (PRPs) to(More)
1. The aim of the present study was to investigate in rat mesenteric artery rings whether low concentrations of vasopressin could modify the contractile responses to noradrenaline and electrical stimulation of perivascular nerves. 2. Vasopressin (10[10]-10[-7] M) caused concentration-dependent contractions (pD2 = 8.36+/-0.09). The V1-receptor antagonist(More)
Chatbots have been used in different scenarios for getting people interested in CS for decades. However, their potential for teaching basic concepts and their engaging effect has not been measured. In this paper we present a software platform called Chatbot designed to foster engagement while teaching basic CS concepts such as variables, conditionals and(More)
The synaptic tagging and capture theory (STC) was postulated by Frey and Morris in 1997 and provided a strong framework to explain how to achieve synaptic specificity and persistence of electrophysiological-induced plasticity changes. Ten years later, the same argument was applied on learning and memory models to explain the formation of long-term memories,(More)
Education is the most traditional means with formative effect on the human mind, learning and memory being its fundamental support. For this reason, it is essential to find different strategies to improve the studentś performance. Based on previous work, we hypothesized that a novel experience could exert an enhancing effect on learning and memory within(More)
Retroactive interference (RI) is a type of amnesia in which a new learning experience can impair the expression of a previous one. It has been studied in several types of memories for over a century. Here, we aimed to study in the long-term memory (LTM) formation of an object-in-context task, defined as the recognition of a familiar object in a context(More)
To the Editor: Human mono-cytic ehrlichiosis is a tick-borne infectious disease caused by Ehrlichia chaffeensis (1). Serologic studies have indicated E. chaffeensis infection in Latin American countries: Venezuela (2), Mexico (3), Argentina (4), Chile (5), and Brazil (6). However, no molecular evidence for E. chaffeensis has been reported. In December 2001,(More)
This paper describes a school intervention to teach fundamental Computer Science (CS) concepts to 3-11 year old students with a multilanguage robot programming platform (using drag and drop, Python and C++ languages) in Argentina. We analyze students' performance and learning process based on multiple choice test and classroom observations. Data show that(More)
The challenge of developing effective separation and purification technologies that leave much smaller energy footprints is greater for carbon dioxide (CO 2) than for other gases. In addition to its involvement in climate change, CO 2 is present as an impurity in biogas and bio-hydrogen (biological production by dark fermentation), in post-combustion(More)
