1. Nervous form of listeriosis in buffaloes
RESUMO: A listeriose é uma doença que afeta várias espécies animais, incluindo o homem, e possui três formas diferentes de apresentação: nervosa, abortiva ou septicêmica. A forma nervosa é causada principalmente pela bactéria Listeria monocytogenes. No Brasil a doença já foi descrita em bovinos, ovinos e caprinos, mas não foram encontrados relat

2. Adrenergic receptor β3 is involved in the memory consolidation process in mice
Attention and emotion have a positive impact on memory formation, which is related to the activation of the noradrenergic system in the brain. The hippocampus and amygdala are fundamental structures in memory acquisition, which is modulated by noradrenaline through the noradrenergic receptors. Pharmacological studies suggest that memory acquisition depends o

3. Perinatal effects of scorpion venoms: maternal and offspring development
Abstract Scorpion envenomation is a public health problem, especially in tropical and subtropical countries. Considering the high incidence of scorpionism in some areas, pregnant women and nursing mothers may be possible victims. Scorpion stings alter the release of neurotransmitters and some cytokines. These mediators act as organizers and programmers in th

4. Is Forced Swimming Immobility a Good Endpoint for Modeling Negative Symptoms of Schizophrenia? - Study of Sub-Anesthetic Ketamine Repeated Administration Effects
ABSTRACT Immobility time in the forced swimming has been described as analogous to emotional blunting or apathy and has been used for characterizing schizophrenia animal models. Several clinical studies support the use of NMDA receptor antagonists to model schizophrenia in rodents. Some works describe the effects of ketamine on immobility behavior but there

5. An ontogenic study of the behavioral effects of chronic intermittent exposure to ayahuasca in mice
Ayahuasca is a beverage obtained from decoctions of the Banisteriopsis caapi plus Psychotria viridis. In religious contexts, ayahuasca is used by different age groups. However, little is known of the effects of ayahuasca during ontogenic development, particularly with regard to the functional characteristics of the central nervous system. Animal models are u

6. Photogrammetry: a Non-Invasive and Objective Method for Detecting Locomotion Problems in Broiler Chickens
ABSTRACT Locomotion problems in broiler chickens can cause economic losses of up to 40% of the total revenues due to carcass condemnation and downgrading at processing. Leg disorders, such as femoral lesions, tibial dyschondroplasia, and spondylolisthesis, substantially impact the welfare of chickens as these disorders can prevent birds from reaching the fee

7. Anatomia óssea, muscular e do movimento das regiões glútea e coxa do Tamanduá bandeira Myrmecophaga tridactyla (Myrmeco phagidae: Pilosa) / Anatomy of movement of the gluteal region and thigh of the giant anteater Myrmecophaga tridactyla (Myrmecophagidae: Pilosa)
CAPÍTULO 2: O tamanduá bandeira é a maior espécie de tamanduá do mundo. É um animal de hábitos terrestres, entretanto apresenta alguma habilidade para escalar árvores e cupinzeiros altos. As estruturas esqueléticas duras são de importância vital, pois unem e protegem os órgãos moles e permitem sustentar o corpo, dão forma e se envolvem no movim

8. Dorsal periaqueductal gray stimulation facilitates anxiety-, but not panic-related, defensive responses in rats tested in the elevated T-maze
The escape response to electrical or chemical stimulation of the dorsal periaqueductal gray matter (DPAG) has been associated with panic attacks. In order to explore the validity of the DPAG stimulation model for the study of panic disorder, we determined if the aversive consequences of the electrical or chemical stimulation of this midbrain area can be dete

9. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the

10. Proposta e avaliação de um modelo computacional de gerador central de padrões / Proposal and evaluation of a computational model of Central Pattern Generator
The concept of Central Pattern Generator-CPG can be described as neural network capable of producing coordinated rhythmic locomotor activity apart from any external rhythm or sensorial stimuli. As this group of neurons are autonomic and are located in the spinal medulla, is experimentally observed that brainless animal‟s exhibit robotized locomotor act

12. Influência do ciclo estral no efeito do diazepam na ansiedade e memória de ratas
Memory and anxiety are related phenomena. Several evidences suggest that anxiety is fundamental for learnining and may facilitate or impair the memory formation process depending of the context. The majority of animal studies of anxiety and fear use only males as experimental subjects, while studies with females are rare in the literature. However, the preva
