1. Action of hormonal therapy in amyotrophic lateral sclerosis: a systematic review
SUMMARY Amyotrophic Lateral Sclerosis (ALS) is a fatal disease characterized by muscle weakness, atrophy, fasciculations, and decreased reflexes due to upper and lower motor neurons death. It can be present in both sexes (55-65 years), but with predominance in males. However, in female patients, ALS presents its first symptoms when they are already postmenop

2. Exosomes secreted from miRNA-29b-modified mesenchymal stem cells repaired spinal cord injury in rats
Exosomes, a kind of extracellular vesicle, are promising therapeutic agents for spinal cord injury (SCI). This article aimed to investigate effects of exosomes secreted from miRNA-29b-modified bone marrow mesenchymal stem cells (BMSCs) on SCI. Exosomes were extracted from BMSCs transfected with miRNA-29b or negative control (miR NC). SCI rats were injected i

3. 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

4. Uremic neuropathy: an overview of the current literature
RESUMO INTRODUÇÃO: A neuropatia periférica (NU) é um distúrbio que afeta o corpo celular, o axônio ou a mielina do motor ou neurônios sensoriais periféricos e ocorre em 60%-100% dos pacientes que são submetidos à diálise por doença renal crônica. A neuropatia urêmica é atribuída à acumulação de resíduos orgânicos, evidente em pacientes

5. Serotonin induces or inhibits neuritic regeneration of leech CNS neurons depending on neuronal identity
Recovery of motor function after central nervous system (CNS) injury is dependent on the regeneration capacity of the nervous system, which is a multifactorial process influenced, among other things, by the role of neuromodulators such as serotonin. The neurotransmitter serotonin can promote neuronal regeneration but there are also reports of it causing rest

7. Interaction between affordance and handedness recognition: a chronometric study
The visualization of tools and manipulable objects activates motor-related areas in the cortex, facilitating possible actions toward them. This pattern of activity may underlie the phenomenon of object affordance. Some cortical motor neurons are also covertly activated during the recognition of body parts such as hands. One hypothesis is that different subpo

8. Efeitos do envelhecimento sobre o sistema nitrérgico dos núcleos da base em humanos
Nitric oxide (NO) is a gaseous molecule that plays a role in a number of physiologic processes. The available evidence suggests that NO is a major neurotransmitter involved in motor control and emotion/behavior modulation. To investigate the distribution and morphology of the nitrergic system in human basal nuclei, we studied samples from the striatum, globu

9. Web-based neuromuscular simulator applied to the teaching of principles of neuroscience
INTRODUCTION: The learning of core concepts in neuroscience can be reinforced by a hands-on approach, either experimental or computer-based. In this work, we present a web-based multi-scale neuromuscular simulator that is being used as a teaching aid in a campus-wide course on the Principles of Neuroscience. METHODS: The simulator has several built-in indivi

10. Myosin Va is developmentally regulated and expressed in the human cerebellum from birth to old age
Myosin Va functions as a processive, actin-based motor molecule highly enriched in the nervous system, which transports and/or tethers organelles, vesicles, and mRNA and protein translation machinery. Mutation of myosin Va leads to Griscelli disease that is associated with severe neurological deficits and a short life span. Despite playing a critical role in

11. Transplantation of mononuclear cells from human umbilical cord blood promotes functional recovery after traumatic spinal cord injury in Wistar rats
Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate the efficacy of mononuclear cells from human umbilical cord blood in promoting functional recovery when transplanted after a contusion spinal cord injury. Female Wistar rats (12 weeks old) were submitted to spinal injury with a MASC

12. Análise da cinemática dos compartimentos da parede torácica nas posições supino e sentada de pacientes com esclerose lateral amiotrófica
Amyotrophic Lateral Sclerosis (ALS) is characterized by deterioration of upper and lower motor neurons. The main components, which alter the respiratory muscles are the inspiratory, expiratory, and bulbar, leading to chronic respiratory failure. One way to improve gas exchange of these individuals is by employing non-invasive ventilation (NIV). Therefore, th
