1. 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

2. Trans-oral, Carbon Dioxide-Assisted Excision of an Unusual Schwannoma of the Tongue Base: Case Report and Review of the Literature
Abstract Introduction Schwannomas are benign, solitary, encapsulated tumors that may originate at any site of the peripheral nervous system, with the exception of the olfactory and optic nerves. Schwannomas of the base of tongue are very rare, and only sporadic cases are documented. The tongue base represents a challenge for surgeons. Carbon dioxide (CO2)

3. Meningoencephalitis due to Naegleria fowleri in cattle in southern Brazil
Resumo Naegleria fowleri é uma ameba de vida livre, comumente encontrada no meio ambiente, principalmente em água doce e no solo. Este protozoário é ocasionalmente associado a casos fatais de doença do sistema nervoso central em seres humanos e espécies animais. No presente trabalho, um caso de meningoencefalite por Naegleria fowleri em um bovino na re

4. Expression and Localization of Olfactory Receptor AcerOr1 from Chinese Honey Bee, Apis cerana cerana (Hymenoptera, Apidae)
ABSTRACT Olfactory receptors are essential for recognition and detection of odor in honeybees. Although we have cloned and characterized the sequence of olfactory receptor AcerOr1 before, the tissue distribution and location of this gene in the nurse and the forager worker Apis cerana cerana were not very clear. To further investigate this information of Ace

5. Olfaction in Neurologic and Neurodegenerative Diseases: A Literature Review
Introduction Loss of smell is involved in various neurologic and neurodegenerative diseases, such as Parkinson disease and Alzheimer disease. However, the olfactory test is usually neglected by physicians at large.
Objective The aim of this study was to review the current literature about the relationshi

6. Estresse pré-natal e suas repercussões sobre o cuidado maternal e comportamento de ratos a curto e a longo prazo
In humans and rodents, stress during pregnancy has produced offspring with high levels of anxiety, impaired learning and memory, changes in maternal care and social behavior deficits. Most prenatal stress protocols have attributed their results to the vulnerability of the intrauterine period. However, studies show that the consequences caused by this action

7. Enantiomeric distribution of key volatile components in Citrus essential oils
Citrus as many other plants present characteristic distribution of some enantiomers, thus it is often possible to use this parameter for identification, characterization, genuineness, and pharmacological activity assessment. In particular, it is possible to reveal adulteration of different nature, such as addition of synthetic compounds, or natural component

8. The neurobiology of infant maternal odor learning
Infant rats must learn to identify their mother’s diet-dependent odor. Once learned, maternal odor controls pups’ approach to the mother, their social behavior and nipple attachment. Here we present a review of the research from four different laboratories, which suggests that neural and behavioral responses to the natural maternal odor and neonatal lear

10. Estudo neuroquímico do núcleo pré-mamilar ventral nos animais submissos durante os encontros agonísticos sociais. / Neurochemic study of the premammillary ventralis nucleus on submissive animals during social agonistic encounters.
Aggressive behavior occurs when the interests of one or more individuals conflict. Territory is one of these interests, and the resident intruder paradigm is widely used to observe the expression of social agonistic behaviors. The dominance behavior has been studied under several views and it was shown that it can be raised by the presence of the female, its

11. RIC-8B, a putative GEF of the olfactory system, interacts with Gαolf, Gβ1 e Gγ13 / Ric-8B, uma GEF putativa do sistema olfatório, interage com Gαolf, Gβ1 e Gγ13
The mammalian olfactory system detects small amounts of thousands of different chemical compounds. Odorant perception starts when an odorant in the air binds to an olfactory receptor (OR). ORs belong to the super family of G-protein coupled receptors (GPCRs). Even though the odorant signaling pathway is well known, little is known about its modulators. In 20

12. Comparação estatística de performance de métodos de redes neurais para sistema de olfação biológica.
One of the human senses that has several aspects get to be elucidated is the olfactory sense. Therefore, many scientists have been studying this sense in order to better understand how does the information processing happens until the brain recognize it. There were lots of theories regarding olfactory system functioning, in which its authors try to explain h
