1. Extrapulmonary manifestations of COVID-19 in children: a comprehensive review and pathophysiological considerations
ABSTRACT Objective: The aim of this review was to summarize the most common extrapulmonary manifestations in pediatric patients with COVID-19, as well as to discuss clinical, epidemiological, and pathophysiological aspects of these clinical presentations in children. Source of data: An extensive search of literature was performed in order to identify pedia

3. Preference of Neoseiulus californicus (Acari: Phytoseiidae) for volatiles of Bt maize induced by multiple herbivory
ABSTRACT Plant indirect induced defenses against herbivores are characterized by the production of plant volatiles that to attract natural enemies. The objective of this study was to evaluate whether the attack of the two-spotted spider mite Tetranychus urticae or the multiple herbivory of T. urticae together with the fall armyworm Spodoptera frugiperda are

4. Rabbit olfactory stem cells. Isolation protocol and characterization
PURPOSE: To describe a new technique for isolation of a mesenchymal stem cells (MSCs) population from the olfactory mucosa in rabbits. METHODS: Olfactory stem cells (OSCs) were retrieved from under the cribriform plate of the Ethmoid bone. Several assays were accomplished to characterize the cell population and attest its viability in vitro. The cells were

5. A new cultural adaptation of the University of Pennsylvania Smell Identification Test
OBJECTIVES: The University of Pennsylvania Smell Identification Test, a test of olfactory function that is widely used by otolaryngologists, geriatricians, and neurologists, has been translated into more than a dozen languages. In some instances, cultural and socioeconomic factors have necessitated changes in the odorant items or the response alternatives to

6. Sensory response of the egg parasitoid Telenomus podisi to stimuli from the bug Euschistus heros.
The objective of this work was to study the foraging behavior of Telenomus podisi Ashmead (Hymenoptera: Scelionidae) in the presence of stimuli from its host, Euschistus heros (Heteroptera: Pentatomidae). The stimuli selected were: egg mass; virgin males and females; volatile extracts of sexually mature males and females; components of male sex pheromone; a

7. Efeito do pentilenotetrazol e do midazolam na aquisição e na expressão da resposta defensiva de ratos submetidos ao condicionamento olfatório de medo
Pavlovian fear conditioning or first-order fear conditioning has been widely used to study the neuroanatomical, cellular and molecular basis of fear. This paradigm occurs when an emotionally neutral stimulus is presented in conjunction with an aversive unconditioned stimulus (US). After one or several pairings the stimulus, previously neutral, acquires the a

8. Behavioral and olfactory antennal responses of Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae) workers to their dufour gland secretion
Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract

9. Da epidemiologia para a neurociÃncia: entendendo NeurÃnios disparantes acoplados eletricamente atravÃs do Modelo sirs estocÃstico na rede hipercÃbica
The response function of individual sensory spiking neurons (ring rate vs. stimulus intensity) has a small dynamic range. For example, in olfactory sensory neurons, only ~ 10 dB of stimulus intensity can be reasonably coded, if saturation and low-stimulus noise were to be avoided. This is in stark contrast with the large dynamic range observed in the next sy

10. Computational simulation of the vertebrate olfactory system. / Simulação computacional do sistema olfativo de vertebrados.
This work describes a biologically plausible simulation of the olfactory system of vertebrates. The constructed model was capable of reproducing satisfactorily important characterisitics observed in the vertebrate olfactory system, including the reception of different concentrations and odor types at the epithelium and the propagation of this information to

11. ConstruÃÃo de um nariz artificial usando redes neurais
The animals interact with environment in several ways. The smell around them has an extremely importance in the information transport, essential for survival. Such as for the animals, the smell plays an important rule for human beings. Due to this importance, the study in the human olfactory system is very helpful and started very long time ago. Although it

12. Quantitative Genetic Variation of Odor-Guided Behavior in a Natural Population of Drosophila Melanogaster
Quantitative genetic variation in behavioral response to the odorant, benzaldehyde, was assessed among a sample of 43 X and 35 third chromosomes extracted from a natural population and substituted into a common inbred background. Significant genetic variation among chromosome lines was detected. Heritability estimates for olfactory response, however, were lo
