High expression of nicotinamide N-methyltransferase in patients with sporadic Alzheimer’s disease
(2021) [Artigo de periódico]We have previously shown that the expression of nicotinamide N-methyltransferase (NNMT) is significantly increased in the brains of patients who have died of Parkinson’s disease (PD). In this study, we have compared the ... -
High frequency of potentially pathogenic yeast species in goat’s raw milk and creamed cheese in Southern Brazil
(2009) [Artigo de periódico]Existem poucos relatos sobre isolamento, contagem e identificação de leveduras no leite de cabra in natura e derivados. O objetivo desse estudo foi avaliar a diversidade de leveduras encontradas no leite de cabra cru e no ... -

High-Frequency Sequences in the Quaternary of Pelotas Basin (coastal plain): a record of degradational stacking as a function of longer-term base-level fall
(2017) [Artigo de periódico]The aim of this work was to analyze the sedimentary record of the coastal plain of Pelotas Basin, placing it in the context of temporal and spatial scales, and proposing a stratigraphic hierarchical framework. The coastal ... -
High glucose-mediated oxidative stress impairs cell migration
(2011) [Artigo de periódico]Deficient wound healing in diabetic patients is very frequent, but the cellular and molecular causes are poorly defined. In this study, we evaluate the hypothesis that high glucose concentrations inhibit cell migration. ... -
High interpopulation homogeneity in Central Argentina as assessed by Ancestry Informative Markers (AIMs)
(2015) [Artigo de periódico]The population of Argentina has already been studied with regard to several genetic markers, but much more data are needed for the appropriate definition of its genetic profile. This study aimed at investigating the admixture ... -
High levels of catalase in SOD mutants of Saccharomyces cerevisae in high aeration conditions
(2005) [Artigo de periódico]Saccharomyces cerevisiae mutants deficient in superoxide dismutase genes (sod1Δ, sod2Δ and sod1Δsod2Δ mutants) in a stationary phase of growth under high aeration conditions were subjected to H2O2 stress. All the mutants ... -
High polymorphism in genes encoding antigen B from human infecting strains of Echinococcus granulosus
(2005) [Artigo de periódico]Echinococcus granulosus antigen B (AgB) is encoded by a gene family and is involved in the evasion of the host immune response. E. granulosus exists as a number of strains (G1–G10) that differ in biological characteristics. ... -
High-risk screening and diagnosis of inborn errors of metabolism : a practical guide for laboratories
(2018) [Artigo de periódico]Inborn errors of metabolism (IEM) are a large and heterogeneous group of genetic diseases. In most of these conditions, the presence of variants in specific genes leads to enzyme deficiencies that affect a particular ... -
High saturated fat and low carbohydrate diet decreases lifespan independent of body weight in mice
(2013) [Artigo de periódico]Background: Obesity is a health problem that is reaching epidemic proportions worldwide. We investigated the effects of a life-long high saturated fat and low carbohydrate (HF) diet on the body mass, glucose tolerance, ... -
High vancomycin resistance among biofilms produced by staphylococcus species isolated from central venous catheters
(2011) [Artigo de periódico]Biofilm production is an important mechanism that allows microbes to escape host defences and antimicrobial therapy. Vancomycin has been used largely for the treatment of methicillin-resistant staphylococcal infections. ... -

Hipertensão arterial sistêmica : estudos diagnósticos
(2005) [Artigo de periódico]Confirmação diagnóstica e avaliação de repercussão sobre órgãos-alvo são passos críticos na avaliação de pacientes hipertensos. Demonstramos a importância da aferição repetida da pressão arterial, do tamanho do manguito e ... -
Hipertensão arterial sistêmica : estudos terapêuticos
(2005) [Artigo de periódico]O tratamento da hipertensão arterial sistêmica visa à prevenção primária e secundária de doença cardiovascular e renal. Um conjunto extenso de ensaios clínicos randomizados demonstrou que diuréticos em baixa dose consistem ... -
Hipertensão arterial sistêmica : prevalência e mecanismos fisiopatogênicos
(2005) [Artigo de periódico]A prevalência de hipertensão arterial, agravo de saúde com distribuição internacional, também é alta em Porto Alegre. Seus fatores de risco – obesidade, predisposição familiar, consumo abusivo de bebidas alcoólicas – foram ... -
Histaminergic system in brain disorders : lessons from the translational approach and future perspectives
(2014) [Artigo de periódico]Histamine and its receptors were first described as part of immune and gastrointestinal systems, but their presence in the central nervous system and importance in behavior are gaining more attention. The histaminergic ... -
Histological analysis of pre-transplant deceased donor renal biopsies and its association with long-term graft survival and function
(2018) [Artigo de periódico]Background: Pre-implantation kidney biopsy is a diagnostic tool used for deciding whether to accept an expanded-criteria deceased donor graft. However, the study of histopathological lesions in renal compartments as ... -
