13. Effects of Heat Stress on the Development of GABAergic Neurons in the HPG Axis of Wenchang Chicks
ABSTRACT This study conducted an in-depth investigation on the development of GABAergic neurons and their receptors in HPG axis-related target organs of Wenchang chicks under heat stress. One-day-old healthy Wenchang chicks were randomly divided into control (CK) and heat stress (HS) groups. Chicks in the HS group were placed in a 40±0.5°C climatic chamber

14. Oxiracetam ameliorates cognitive deficits in vascular dementia rats by regulating the expression of neuronal apoptosis/autophagy-related genes associated with the activation of the Akt/mTOR signaling pathway
Oxiracetam (ORC) is a commonly used nootropic drug for improving cognition and memory impairments. The therapeutic effect and underlying mechanism of ORC in vascular dementia (VaD) treatment remain unknown. In this study, 3-month-old male Sprague-Dawley rats with permanent bilateral common carotid artery occlusion-induced VaD were treated orally with low (10

15. Stem-cell therapy for hearing loss: are we there yet?
Resumo Introdução: Nos mamíferos, as células ciliadas e os neurônios auditivos não apresentam capacidade regenerativa. Assim, os danos a esses tipos celulares são permanentes e levam à perda auditiva. Contudo, como não há tratamento que restabeleça a função auditiva, as terapias regenerativas utilizando células-tronco representam uma alternati

16. DOES THE RHEUMATOID ARTHRITIS AFFECT THE ENTERIC NERVOUS SYSTEM?
RESUMO CONTEXTO: Poucos estudos sobre doenças artríticas têm sido realizados para verificar a presença de neurodegeneração. Diante do aumento do estresse oxidativo e dos efeitos extra-articulares da artrite reumatoide, estudos gastrointestinais devem ser investigados visando uma melhor compreensão dos efeitos sistêmicos da doença no sistema nervos

17. Severe Outbreak of Avian Encephalomyelitis in Laying Hens in Northeastern Brazil
ABSTRACT This paper describes the epidemiological, clinical and pathological aspects of an avian encephalomyelitis (AE) outbreak in commercial laying hens in Northeastern Brazil. The disease affected 23,409 layers (from day one until 100 weeks) leading to mortality of 16.5% (5,049/30,600) of the flock. Twenty laying hens were clinically examined, and blood s

18. Antinociceptive effect of PnTx4(5-5), a peptide from Phoneutria nigriventer spider venom, in rat models and the involvement of glutamatergic system
ABSTRACT Background: The venom of Phoneutria nigriventer spider is a source of numerous bioactive substances, including some toxins active in insects. An example is PnTx4(5-5) that shows a high insecticidal activity and no apparent toxicity to mice, although it inhibited NMDA-evoked currents in rat hippocampal neurons. In this work the analgesic activity o

19. Association between BDNF G196A (Val66Met) polymorphism and cognitive impairment in patients with Parkinson's disease: a meta-analysis
Brain-derived neurotrophic factor (BDNF) is widely expressed in the central nervous system and prolongs the survival of dopaminergic neurons in the substantia nigra. Several studies have recently investigated the association between BDNF G196A (Val66Met), a single nucleotide polymorphism influencing cognitive processes, and cognitive impairment in Parkinson'

20. Polioencephalomalacia (PEM) in calves associated with excess sulfur intake
RESUMO: A polioencefalomalacia (PEM) é a caracterização morfológica para o amolecimento da substância cinzenta encefálica, e uma de suas principais etiologias é a ingestão excessiva de enxofre. Este trabalho descreve um surto desta enfermidade em bezerros de um a três meses de idade em uma propriedade de Santa Catarina. O lote era composto por 27 be

21. The role of ischemic preconditioning in the expression of apoptosis-related genes in a rat model of intestinal ischemia-reperfusion injury
Abstract Purpose: To analyze the effects of ischemic preconditioning (IPC) in the expression of apoptosis-related genes in rat small intestine subjected to ischemia and reperfusion. Methods: Thirty anesthetized rats underwent laparotomy and were drive into five groups: control (CG); ischemia (IG); ischemia and reperfusion (IRG); IPC and ischemia (IG+IPC)

22. Effect of acetylsalicylic acid on total myenteric neurons in mice experimentally infected with Trypanosoma cruzi
Abstract: We investigated the effects of acetylsalicylic acid (ASA) on the total myenteric neuronal population in the descending colon in Trypanosoma cruzi-infected mice. Thirty-five male Swiss mice, 60 days old, were divided into a control group (C group), control group treated with ASA (CA group), infected group (I group), and infected group treated with A

23. Neuroprotective properties of RT10, a fraction isolated from Parawixia bistriata spider venom, against excitotoxicity injury in neuron-glia cultures
Abstract Background: L-Glutamate (L-Glu), the major excitatory neurotransmitter in the mammalian Central Nervous System (CNS), is essential to cognitive functions. However, when L-Glu is accumulated in large concentrations at the synaptic cleft, it can induce excitotoxicity that results in secondary damage implicated in many neurological disorders. Current
