Hemócitos de Bradybaena similaris e Megalobulimus abbreviatus (Gastropoda, Stylommatophora)
(2014) [Journal article]Hemocytes act in the defense system against invading organisms, foreign particles aiding the recognition of what is own to the body of gastropods and what is not. Information and studies on the hemocytes in species of ... -
Hemodialysis improves endothelial venous function in end-stage renal disease
(2008) [Journal article]The objective of the present study was to determine the acute effect of hemodialysis on endothelial venous function and oxidative stress. We studied 9 patients with end-stage renal disease (ESRD), 36.8 ± 3.0 years old, ... -
Hemodynamic changes and autonomic nervous system after acute myocardial infarction in rats submitted to left coronary artery ligation
(2018) [Journal article]Heart failure is a clinical syndrome characterized by sympathetic/ renin-angiotensin system activation, besides parasympathetic activity attenuation. In the initial phase of HF, following a myocardial infarction, there is ... -

Hepatic glycogen storage diseases are associated to microbial dysbiosis
(2019) [Journal article]Introduction The gut microbiome has been related to several features present in Glycogen Storage Diseases (GSD) patients including obesity, inflammatory bowel disease (IBD) and liver disease. Objectives The primary objective ... -
Herança da estatura de planta e do comprimento da panícula principal no cruzamento entre avena sativa l. e avena sterilis l.
(1999) [Journal article]A espécie selvagem Avena sterilis L. tem sido amplamente utilizada para cruzamento com aveia cultivada, pela alta afinidade existente entre ambas, o que possibilita um aumento na variabilidade genética e transferência de ... -
Hereditary non-polipomatous colorectal cancer : hereditary predisposition, diagnosis and prevention
(2005) [Journal article]Background - Colorectal cancer is the third in frequency and the second in mortality in developed countries. In Brazil, it is among the six more common malignant neoplasias. About 20% of colorectal tumors have some hereditary ... -
Herpesvírus bovinos (BoHV-1.1 e BoHV-1.2b) em forma infecciosa em encéfalos de bovinos submetidos ao diagnóstico de raiva no estado do Rio Grande do Sul
(2010) [Journal article]Verificou-se a incidência de herpesvírus bovinos (BoHVs) em encéfalos de bovinos submetidos ao diagnóstico de raiva no estado do Rio Grande do Sul. Para tanto, amostras coletadas durante dois anos (n=70) foram submetidas ... -
Heterogeneity in extracellular nucleotide hydrolysis among clinical isolates of Trichomonas vaginalis
(2005) [Journal article]Trichomonas vaginalis is a parasitic protozoan that causes trichomonosis, a sexually-transmitted disease, with serious sequelae to women and men. As the host–parasite relationship is complex, it is important to investigate ... -
Hibridização genômica comparativa baseada em microarranjos em neonatos com anomalias congênitas : detecção de desequilíbrios cromossômicos
(2015) [Journal article]Objective: To identify chromosomal imbalances by whole-genome microarray-based comparative genomic hybridization (array-CGH) in DNA samples of neonates with congenital anomalies of unknown cause from a birth defects ... -
Higher serum S100b and BDNF levels are correlated with a lower pressure-pain threshold in fibromyalgia
(2014) [Journal article]Background: Fibromyalgia (FM) is conceptualized as a central sensitization (CS) condition, that presents high serum brain-derived neurotrophic factor (BDNF) and neuroglia activation. Although the S100B protein regulates ... -
High expression of nicotinamide N-methyltransferase in patients with sporadic Alzheimer’s disease
(2021) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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 ... -
