Margay (Leopardus wiedii) in the southernmost Atlantic Forest: density and activity patterns under different levels of anthropogenic disturbance
(2020) [Artigo de periódico]The margay (Leopardus wiedii) is a small Neotropical arboreal wild cat. This species is thought to be forest-dependent, although few studies so far have directly evaluated the rela tionships between spatiotemporal aspects ... -
Markedly divergent tree assemblage responses to tropical forest loss and fragmentation across a strong seasonality gradient
(2015) [Artigo de periódico]We examine the effects of forest fragmentation on the structure and composition of tree assemblages within three seasonal and aseasonal forest types of southern Brazil, including evergreen, Araucaria, and deciduous forests. ... -
Marsupial extension in terrestrial isopods (Crustacea, Isopoda, Oniscidea)
(2011) [Artigo de periódico]In Oniscidea, the marsupium is a ventral pouch where the offspring develop independently of an external water source. The marsupium is formed by five pairs of overlapping oostegites that develop in the females during their ... -

Mass spectrometry analysis of surface tension reducing substances produced by a pah-degrading Pseudomonas citronellolis strain
(2008) [Artigo de periódico]In this work we investigated the structure of the iron-stimulated surface tension reducing substances produced by P. citronellolis 222A isolated from a 17-years old landfarming used for sludge treatment in petrochemical ... -
Master regulators connectivity map : a transcription factors-centered approach to drug repositioning
(2018) [Artigo de periódico]Drug discovery is a very expensive and time-consuming endeavor. Fortunately, recent omics technologies and Systems Biology approaches introduced interesting new tools to achieve this task, facilitating the repurposing of ... -
Maternal drinking behavior and fetal alcohol spectrum disorders in adolescents with criminal behavior in southern Brazil
(2012) [Artigo de periódico]Prenatal alcohol exposure can have serious and permanent adverse effects. The developing brain is the most vulnerable organ to the insults of prenatal alcohol exposure. A behavioral phenotype of prenatal alcohol exposure ... -
Maternal high-salt diet alters redox state and mitochondrial function in newborn rat offspring's brain
(2018) [Artigo de periódico]Excessive salt intake is a common feature of Western dietary patterns, and has been associated with important metabolic changes including cerebral redox state imbalance. Considering that little is known about the effect ... -
Maternal outcomes and risk factors for COVID-19 severity among pregnant women
(2021) [Artigo de periódico]Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study ... -

Matrix metalloproteinase gene polymorphisms and susceptibility to systemic sclerosis
(2016) [Artigo de periódico]The major pathological hallmark of the systemic sclerosis (SSc) is skin and internal organ fibrosis, which results from normal tissue architecture alterations and extracellular matrix (ECM) protein deposition. ECM components ... -
Matrix metalloproteinase gene polymorphisms in patients with coronary artery disease
(2007) [Artigo de periódico]Matrix metalloproteinases (MMPs) play an important role in the pathogenesis of atherosclerosis, the pathology underlying the majority of coronary artery disease (CAD). In this study we tested the hypothesis that polymorphic ... -
Matrix stiffness mechanically conditions EMT and migratory behavior of oral squamous cell carcinoma
(2019) [Artigo de periódico]Tumors are composed of heterogeneous phenotypes, each having different sensitivities to the microenvironment. One microenvironment characteristic – matrix stiffness – helps to regulate malignant transformation and invasion ... -
Maturation of pyramidal cells in anterior piriform cortex may be sufficient to explain the end of early olfactory learning in rats
(2020) [Artigo de periódico]Studies have shown that neonate rodents exhibit high ability to learn a preference for novel odors associated with thermotactile stimuli that mimics maternal care. Artificial odors paired with vigorous strokes in rat pups ... -
May polyester with collagen coating mesh decrease the rate of intraperitoneal adhesions in incisional hernia repair?
(2013) [Artigo de periódico]Background - Among meshes used in incisional hernias in open technique repair, the polypropylene is the most commonly used due to flexibility, cellular growth stimulation, satisfactory inflammatory response, easy manipulation ... -
MBL2 gene polymorphisms and its relation to infection in Brazilian systemic lupus erythematosus patients : a 10-years followup study
(2022) [Artigo de periódico]Introduction: Systemic lupus erythematosus (SLE) is a multifactorial disease and MBL2 genetic variants, which are associated to differential peripheral MBL levels, potentially affect its etiology and increase infection ... -
MBSP1: a biosurfactant protein derived from a metagenomic library with activity in oil degradation
(2020) [Artigo de periódico]Microorganisms represent the most abundant biomass on the planet; however, because of several cultivation technique limitations, most of this genetic patrimony has been inaccessible. Due to the advent of metagenomic ... -
Measurement of sulfatides in the amniotic fluid supernatant : a useful tool in the prenatal diagnosis of metachromatic leukodystrophy
(2022) [Artigo de periódico]Metachromatic leukodystrophy (MLD) is an autosomal recessive lysosomal disorder caused by deficiency of arylsulfatase A (ARSA), leading to an accumulation of sulfatides. Sulfatides have been quantified in urine, dried blood ... -
