1. Armadillos and leprosy: from infection to biological model
ABSTRACT Mycobacterium leprae is the primary causative agent of Hansen’s disease or leprosy. Besides human beings, natural infection has been described in animals such as mangabey monkeys and armadillos. Leprosy is considered a global health problem and its complete pathogenesis is still unknown. As M. leprae does not grow in artificial media, armadillos h

2. Production, characterization and toxicology assay of creatine pegylated nanoliposome with polysorbate 80 for brain delivery
ABSTRACT Creatine acts intracellularly as energy buffer and storage, demonstrating protective effects in animal models of neurodegenerative diseases. However, its permeability throught blood-brain barrier (BBB) is reduced. The aim of the present study was developing a carrier to facilitate the delivery of creatine to the central nervous system. Creatine nano

3. Moyamoya syndrome associated with neurofibromatosis type 1 in a pediatric patient
Abstract: Neurofibromatosis type 1 is a multisystem genetic disease of autosomal dominant transmission that reveals important cutaneous manifestations such as café-au-lait spots, multiple neurofibromas, and ephelides in skin fold areas, as well as hamartomatous lesions in the eyes, bones, glands, and central nervous system. Moyamoya disease is a rare progre

4. Effects of N-acetylcysteine on spinal cord oxidative stress biomarkers in rats with neuropathic pain
N-acetylcysteine (NAC) inhibits nociceptive transmission. This effect has been associated partly with its antioxidant properties. However, the effect of NAC on the levels of lipid hydroperoxides (a pro-oxidant marker), content of ascorbic acid (a key antioxidant molecule of nervous tissue) and total antioxidant capacity (TAC) is unknown. Thus, our study asse

5. Zika puzzle in Brazil: peculiar conditions of viral introduction and dissemination - A Review
This article discusses the peculiar conditions that favoured the unexpected introduction of Zika virus into the poorest northeastern region of Brazil in 2015, its speed of transmission to other Brazilian states, other Latin American countries and other regions, and the severity of related neurological disorders in newborns and adults. Contrasting with eviden

6. Exposure to 50 Hz electromagnetic field changes the efficiency of the scorpion alpha toxin
AbstractBackground Extremely low-frequency (50 Hz) electromagnetic field (ELF-EMF) is produced by electric power transmission lines and electronic devices of everyday use. Some phenomena are proposed as “first effects” of ELF-EMF: the discrete changes in the membrane potential and the increase of the calcium channel activity as well as the intracellular

7. Incidence of congenital toxoplasmosis among infants born to HIV-coinfected mothers: case series and literature review
Introduction:There is a paucity of data on the occurrence of congenital toxoplasmosis in children born to mothers dually infected with HIV and Toxoplasma gondii.Objective:To evaluate aspects of the mother–infant pairs associated with vertical transmission of toxoplasmosis in women co-infected with HIV in a referral center for perinatally acquired infection

8. Eosinophilic meningitis caused by Angiostrongylus cantonensis: an emergent disease in Brazil
Eosinophilic meningitis (EoM) is an acute disease that affects the central nervous system. It is primarily caused by infection with the nematode Angiostrongylus cantonensis. This infection was previously restricted to certain Asian countries and the Pacific Islands, but it was first reported in Brazil in 2007. Since then, intermediate and definitive hosts in

9. Uma abordagem neurofisiológica da acetilcolina em plantas de milho hidratadas e sob condições de estresse hídrico / A neurophysiological approach to acetylcholine in maize plants hydrated and under water stress conditions
The occurrence of action potential and neurotransmitters, the major components of animal nervous system, in plants, bacteria and fungi, shows the universality of signaling principles and information transmission in the way of chemical and electrical signals in all organisms. These study topics, along with plant intelligence and vesicular-based auxin transpor

10. Sensitivity and specificity of auditory steady-state response testing
INTRODUCTION: The ASSR test is an electrophysiological test that evaluates, among other aspects, neural synchrony, based on the frequency or amplitude modulation of tones. OBJECTIVE: The aim of this study was to determine the sensitivity and specificity of auditory steady-state response testing in detecting lesions and dysfunctions of the central auditory ne

11. Alterações cardiovasculares de fêmeas de ratos espontaneamente hipertensos (SHR) relacionadas com a idade / Cardiovascular changes in female spontaneously hypertensive rats (SHR) age-related
Hypertension is a major cause of cardiovascular disorders, and the natural progression of this disease may trigger further changes in the circulatory system. Experimental models are widely used in studies on the changes that occur in the cardiovascular system induced by hypertension. The SHR is the model that most closely matches the human hypertension, as i

12. Experimental infection with Neospora caninum in young dogs (Canis familiaris), adults and in pregnant bitches. / Infecção experimental por Neospora caninum em cães (Canis familiaris) jovens, adultos e em cadelas gestantes.
The objectives of this study were to evaluate transplacental transmission of N. caninum in different stages of pregnancy (Exp I) and evaluate different bovine tis.sues as means of transmission of N. caninum in young dogs and adults (Exp II). In Exp I, Three dogs were inoculated with 108 tachyzoites of N. caninum in the third week of gestation, three at 6 six
