(2002) [Artigo de periódico]In the present work we investigated the movement pattern of Spartocera (=Corecoris) dentiventris (Berg) (Hemiptera: Coreidae) adults through the mark-release-recapture method in an experimen- tal tobacco crop (Nicotiana ... -
MSX1 and PAX9 investigation in monozygotic twins with variable expression of tooth agenesis
(2013) [Artigo de periódico]Non-syndromic agenesis of permanent teeth is one of the most common anomalies in human development, a multifactorial characteristic caused by genetic and environmental factors. We describe a pair of monozygotic twins who ... -
Mucopolissacaridose tipo I em cão
(2021) [Artigo de periódico]Background: Mucopolysaccharidoses (MPS) are a group of rare illnesses caused by deficient activity of enzymes required for degradation of glycosaminoglycans (GAGs). Each type of MPS is caused by mutations in one of the ... -
Mucopolysaccharidoses : from understanding to treatment, a century of discoveries
(2012) [Artigo de periódico]After the first description of a patient recognized as a MPS case was made in 1917, several similar cases were described and identified. Observations reported in the middle of the twentieth century concerning the presence ... -
Mucopolysaccharidoses in northern Brazil : targeted mutation screening and urinary glicosaminoglycan excretion in patients undergoing enzyme replacement therapy
(2011) [Artigo de periódico]Mucopolysaccharidoses (MPS) are rare lysosomal disorders caused by the deficiency of specific lysosomal enzymes responsible for glycosaminoglycan (GAG) degradation. Enzyme Replacement Therapy (ERT) has been shown to reduce ... -
Mucopolysaccharidosis I, II, and VI : brief review and guidelines for treatment
(2010) [Artigo de periódico]Mucopolysaccharidoses (MPS) are rare genetic diseases caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of ... -
Mucopolysaccharidosis type VI (Maroteaux-Lamy syndrome) : assessment of joint mobility and grip and pinch strength
(2008) [Artigo de periódico]Objetivo: Descrever o perfil de mobilidade articular e das forças de garra e de pinça de indivíduoscomMPSVI, além de sua correlação com a excreção urinária de glicosaminoglicanos, atividade da ARSB e distância percorrida ... -
Mucopolysaccharidosis VII in Brazil : natural history and clinical findings
(2021) [Artigo de periódico]Background: Mucopolysaccharidosis type VII (MPS VII), also known as Sly syndrome, caused by defciency of the lysosomal enzyme β-glucuronidase, is an ultra-rare disorder with scarce epidemiological data and few publications ... -
As mudanças nas concepções de ciência e educação na história do ocidente : a conjunturalidade dessas noções e suas adaptações para o século XXI
(2020) [Artigo de periódico]As concepções que temos de ciência e educação são historicamente construídas de acordo com especificidades conjunturais, passando ora por visões simplistas, ora por visões mais complexas. Passamos por mudanças de paradigmas ... -
Multicentric glioblastoma arising in two unusual sites : cerebellum and thalamus
(2013) [Artigo de periódico]Multicentric glioblastomas (MGBM) arising in infra/supratentorial regions are uncommon lesions. The authors report a case of MGBM in a 61 year-old female patient, who presented a sudden onset of left hemiplegia. The magnetic ... -
Multi-criteria analysis applied to landslide susceptibility mapping
(2017) [Artigo de periódico]This paper presents the application of a multi-criteria analysis (MCA) tool for landslide susceptibility assessment in Porto Alegre municipality, southern Brazil. A knowledge driven approach was used, aiming to ensure an ... -
Multidrug resistance in Enterococci isolated from wild pampas foxes (Lycalopex gymnocercus) and Geoffroy's Cats (Leopardus geoffroyi) in the Brazilian pampa biome
