Se incluyeron 50 gestantes con preeclampsia como los casos (grupo A) y un grupo control seleccionado por tener una edad y un índice de masa corporal similares al grupo de estudio que consistió en 50 embarazadas normotensas sanas (grupo B). ...



The Interplay between Reproductive Social Stimuli and Adult Olfactory Bulb Neurogenesis
submitted by moreonni 14 minutes ago - Topic: Health
Adult neurogenesis is a striking form of structural plasticity that adapts the brain to the changing world. Accordingly, new neuron production is involved in cognitive functions, such as memory, learning, and pattern separation. Recent data in rodents indicate a close link between adult neurogenesis and reproductive social behavior. This provides a key to unravel the functional meaning of adult...

Generality of a congruity effect in judgements of relative order
submitted by jdenh 14 minutes ago - Topic: Health
The judgement of relative order (JOR) procedure is used to investigate serial-order memory. Measuring response times, the wording of the instructions (whether the earlier or the later item was designated as the target) reversed the direction of search in subspan lists (Chan, Ross, Earle, & Caplan Psychonomic Bulletin & Review, 16, 945–951, 2009). If a similar congruity effect applied ...


An RT distribution analysis of relatedness proportion effects in lexical decision and semantic categorization reveals different mechanisms
submitted by jdenh 14 minutes ago - Topic: Health
The magnitude of the semantic priming effect is known to increase as the proportion of related prime–target pairs in an experiment increases. This relatedness proportion (RP) effect was studied in a lexical decision task at a short prime–target stimulus onset asynchrony (240 ms), which is widely assumed to preclude strategic prospective usage of the prime. The analysis of the reaction time ...

What can we learn about visual attention to multiple words from the word–word interference task?
submitted by jdenh 14 minutes ago - Topic: Health
In this work, we develop an empirically driven model of visual attention to multiple words using the word–word interference (WWI) task. In this task, two words are simultaneously presented visually: a to-be-ignored distractor word at fixation, and a to-be-read-aloud target word above or below the distractor word. Experiment 1 showed that low-frequency distractor words interfere more than hig...


Low CO2 results in a rearrangement of carbon metabolism to support C4 photosynthetic carbon assimilation in Thalassiosira pseudonana
submitted by jvb234 17 minutes ago - Topic: Biology
The mechanisms of carbon concentration in marine diatoms are controversial. At low CO2, decreases in O2 evolution after inhibition of phosphoenolpyruvate carboxylases (PEPCs), and increases in PEPC transcript abundances, have been interpreted as evidence for a C4 mechanism in Thalassiosira pseudonana, but the ascertainment of which proteins are responsible for the subsequent decarboxylation and...

Polyploidy: adaptation to the genomic environment
submitted by jvb234 17 minutes ago - Topic: Biology
Genomic evidence of ancestral whole genome duplication (WGD) and polyploidy is widespread among eukaryotic species, and especially among plants. WGD is thought to provide the raw material for adaptation in the form of duplicated genes, and polyploids are thought to benefit from both physiological and genetic buffering. Comparatively little attention has focused on the genomic challenge of polyp...


The impact of domestication on resistance to two generalist herbivores across 29 independent domestication events
submitted by jvb234 17 minutes ago - Topic: Biology
The domestication of crops is among the most important innovations in human history. Here, we test the hypothesis that cultivation and artificial selection for increased productivity of crops reduced plant defenses against herbivores. We compared the performance of two economically important generalist herbivores – the leaf-chewing beet armyworm (Spodoptera exigua) and the phloem-feeding gree...

Hitchhiker's guide to multi-dimensional plant pathology
submitted by jvb234 17 minutes ago - Topic: Biology
Filamentous pathogens pose a substantial threat to global food security. One central question in plant pathology is how pathogens cause infection and manage to evade or suppress plant immunity to promote disease. With many technological advances over the past decade, including DNA sequencing technology, an array of new tools has become embedded within the toolbox of next-generation plant pathol...

Evidence for biological denitrification inhibition (BDI) by plant secondary metabolites
submitted by jvb234 17 minutes ago - Topic: Biology
Previous studies on the effect of secondary metabolites on the functioning of rhizosphere microbial communities have often focused on aspects of the nitrogen (N) cycle but have overlooked biological denitrification inhibition (BDI), which can affect plant N-nutrition. Here, we investigated the BDI by the compounds of Fallopia spp., an invasive weed shown to be associated with a low potential de...

The chloroplast view of the evolution of polyploid wheat
submitted by jvb234 17 minutes ago - Topic: Biology
Polyploid wheats comprise four species: Triticum turgidum (AABB genomes) and T. aestivum (AABBDD) in the Emmer lineage, and T. timopheevii (AAGG) and T. zhukovskyi (AAGGAmAm) in the Timopheevi lineage. Genetic relationships between chloroplast genomes were studied to trace the evolutionary history of the species. Twenty-five chloroplast genomes were sequenced, and 1127 plant accessions were ...
