RESUMO

BACKGROUND: Corticosteroids are used in paediatric heart surgery to attenuate systemic inflammatory response. Glycocalyx regulates vascular permeability, shear stress and cell adhesion on the endothelium. Syndecan-1 serves as a biomarker of glycocalyx degradation. Hydrocortisone decreased endothelial glycocalyx degradation in an experimental model. Our hypothesis was that high-dose methylprednisolone decreases glycocalyx degradation as measured by plasma sydecan-1 concentration in children undergoing cardiac surgery. METHODS: Two double-blinded, randomized, placebo-controlled trials were conducted. In the first trial ('neonatal trial'), 40 neonates undergoing open heart surgery received either 30 mg/kg intravenous methylprednisolone (n = 20) or placebo (n = 20). In the second trial ('VSD trial'), 45 infants and very young children, undergoing ventricular or atrioventricular septal defect correction received one of the following: 30 mg/kg of methylprednisolone intravenously after anaesthesia induction (n = 15), 30 mg/kg methylprednisolone in the cardiopulmonary bypass prime solution (n = 15) or placebo (n = 15). Plasma syndecan-1 concentrations were measured. Results were expressed both as absolute concentrations and in relative concentrations as multiples of the baseline values of syndecan-1. RESULTS: There were no statistically significant differences between the neonate trial groups for absolute syndecan-1 concentrations. However, operative administration of methylprednisolone to neonates significantly reduced the relative increases of syndecan-1 at weaning from cardiopulmonary bypass (P = 0.008) and at 6 h post-operatively (P = 0.018). There were no statistically significant differences in absolute or relative increases of syndecan-1 between the VSD trial study groups. CONCLUSION: High-dose methylprednisolone reduces shedding of glycocalyx in neonates after complex cardiac surgery but not in older infants after repair of VSD/AVSD with shorter ischaemia times.

RESUMO

The study investigated how the concentration and composition of purified tannin extracts, at various inclusion rates, affect the ruminal in vitro fermentation parameters. Tannin extracts were isolated from four different forage species: birdsfoot trefoil (Lotus corniculatus), sulla (Hedysarum coronarium), big trefoil (Lotus pedunculatus), and salad burnet (Sanguisorba minor). Plants extracts were purified by Sephadex LH-20 gel chromatography and analyzed by UPLC-ESI-MS/MS. The results showed a large variation among the extracts from different species in terms of tannin composition and structural features. The extracts from salad burnet were dominated by hydrolysable tannins, comprising mainly ellagitannins. The extracts derived from sulla and big trefoil contained predominantly proanthocyanidins (PA), primarily composed of prodelphinidins with high mean degree of polymerisation (mDP). Birdsfoot trefoil extracts comprised procyanidin-rich PAs with low mDP. To determine whether the combined presence of tannins and flavonoid together lead to synergistic or antagonistic effects, the tannin extracts were incubated both with or without rutin at concentrations of 10, 20, and 30 g/kg DM, using a base substrate of perennial ryegrass (Lolium perenne, control). In general, all the tannin extracts decreased methane (CH4) production compared to the control, while no significant effect of rutin was observed on both gas (GP) and CH4 production, neither pure, nor in the simultaneous presence of tannins. The highest CH4 reduction (15%, at 30 g/kg DM) was observed from sulla and big trefoil extracts compared to control, but this was also supplemented with a concomitant reduction in GP (11%) indicating a reduction in feed digestibility. The extracts from birdsfoot trefoil and salad burnet reduced CH4 by up to 12% without significantly reducing GP, indicating the importance of tannin composition on ruminal fermentation.

RESUMO

Gastrointestinal nematode (GIN) infections impact small ruminant health, welfare, and production across farming systems. Rising anthelmintic resistance and regulation of synthetic drug use in organic farming is driving research and development of sustainable alternatives for GIN control. One alternative is the feeding of plants that contain secondary metabolites (PSMs) e.g., proanthocyanidins (PA, syn. condensed tannins) that have shown anthelmintic potential. However, PSMs can potentially impair performance, arising from reduced palatability and thus intake, digestibility or even toxicity effects. In this study, we tested the trade-off between the antiparasitic and anti-nutritional effects of heather consumption by lambs. The impact of additional feeding of a nematophagous fungus (Duddingtonia flagrans) on larval development was also explored. Lambs infected with Teladorsagia circumcincta or uninfected controls, were offered ad libitum heather, or a control chopped hay for 22 days during the infection patent period. Eight days into the patent period, parasitised lambs were supplemented (or remained unsupplemented) with D. flagrans for a 5-day period. Performance and infection metrics were recorded, and polyphenol levels in the heather and control hay were measured to investigate their association with activity. The lambs consumed heather at approximately 20% of their dry matter intake, which was sufficient to exhibit significant anthelmintic effects via a reduction in total egg output (P = 0.007), compared to hay-fed lambs; the magnitude of the reduction over time in heather fed lambs was almost 10-fold compared to control lambs. Negative effects on production were shown, as heather-fed lambs weighed 6% less than hay-fed lambs (P < 0.001), even though dry matter intake (DMI) of heather increased over time. D. flagrans supplementation lowered larval recovery in the faeces of infected lambs by 31.8% (P = 0.003), although no interactions between feeding heather and D. flagrans were observed (P = 0.337). There was no significant correlation between PA, or other polyphenol subgroups in the diet and egg output, which suggests that any association between heather feeding and anthelmintic effect is not simply and directly attributable to the measured polyphenols. The level of heather intake in this study showed no antagonistic effects on D. flagrans, demonstrating the methods can be used in combination, but provide no additive effect on overall anthelmintic efficacies. In conclusion, heather feeding can assist to reduce egg outputs in infected sheep, but at 20% of DMI negative effects on lamb performance can be expected which may outweigh any antiparasitic benefits.

RESUMO

An earlier study (Borg et al., Am J Psychiatry 2003) found an inverse correlation between [carbonyl-(11)C]WAY-100635 ligand binding to 5-HT(1A) receptors and scores for self-transcendence, but no other of the six dimensions of the Temperament and Character Inventory, in a group of healthy males. The aim of this study was to investigate if the finding of an inverse correlation between spirituality and 5-HT(1A) could be seen in patients suffering from major depressive disorder or replicated among healthy volunteers. A total of 23 patients with major depressive disorder and 20 healthy volunteers were examined with PET using [carbonyl-(11)C]WAY-100635 as the radioligand. The personality traits were measured using the Finnish version of the Temperament and Character Inventory and correlated with ligand binding (BP). No significant correlations were found between the different Temperament and Character Inventory subscales and BP in any of the studied brain regions (amygdala, anterior cingulate cortex, dorsal raphe nuclei, dorsolateral prefrontal cortex, angular gyrus, inferior, middle, and superior temporal gyri, medial prefrontal cortex orbitofrontal cortex, hippocampus, insular cortex, subgenual anterior cingulate cortex, supramarginal gyrus, ventrolateral prefrontal cortex, and posterior cingulate cortex). These results do not support the idea that the serotonin system forms the biological basis of spiritual experiences among patients suffering from major depressive disorder or among healthy volunteers.

RESUMO

Root herbivores can affect plant fitness, and roots often contain the same secondary metabolites that act as defenses in shoots, but the ecology and evolution of root chemical defense have been little investigated. Here, we investigated genetic variance, heritability, and correlations among defensive phenolic compounds in shoot vs. root tissues of common evening primrose, Oenothera biennis. Across 20 genotypes, there were roughly similar concentrations of total phenolics in shoots vs. roots, but the allocation of particular phenolics to shoots vs. roots varied along a continuum of genotype growth rate. Slow-growing genotypes allocated 2-fold more of the potential pro-oxidant oenothein B to shoots than roots, whereas fast-growing genotypes had roughly equivalent above and belowground concentrations. Phenolic concentrations in both roots and shoots were strongly heritable, with mostly positive patterns of genetic covariation. Nonetheless, there was genotype-specific variation in the presence/absence of two major ellagitannins (oenothein A and its precursor oenothein B), indicating two different chemotypes based on alterations in this chemical pathway. Overall, the presence of strong genetic variation in root defenses suggests ample scope for the evolution of these compounds as defenses against root herbivores.

RESUMO

This study explored genetic variation and co-variation in multiple functional plant traits. Our goal was to characterize selection, heritabilities and genetic correlations among different types of traits to gain insight into the evolutionary ecology of plant populations and their interactions with insect herbivores. In a field experiment, we detected significant heritable variation for each of 24 traits of Oenothera biennis and extensive genetic covariance among traits. Traits with diverse functions formed several distinct groups that exhibited positive genetic covariation with each other. Genetic variation in life-history traits and secondary chemistry together explained a large proportion of variation in herbivory (r(2) = 0.73). At the same time, selection acted on lifetime biomass, life-history traits and two secondary compounds of O. biennis, explaining over 95% of the variation in relative fitness among genotypes. The combination of genetic covariances and directional selection acting on multiple traits suggests that adaptive evolution of particular traits is constrained, and that correlated evolution of groups of traits will occur, which is expected to drive the evolution of increased herbivore susceptibility. As a whole, our study indicates that an examination of genetic variation and covariation among many different types of traits can provide greater insight into the evolutionary ecology of plant populations and plant-herbivore interactions.

RESUMO

The ability of 32 purified and characterized hydrolyzable tannins to form insoluble complexes with model protein bovine serum albumin was investigated with a turbidimetric 96-well plate reader method. The results showed a clear relationship between the hydrolyzable tannin structure and the intensity of haze that formed during the tannin-protein complexation. In addition to molecular weight, structural features such as number of galloyl groups, degree of oxidative coupling between the galloyls, positional isomerism, and cyclic vs acyclic glucose core were the major structural features that affected the ability of the monomeric hydrolyzable tannins to form insoluble complexes with bovine serum albumin. While oligomers were superior to monomers in their capability to precipitate the model protein, their activity depended less on the functional groups, but mostly on their size and overall flexibility. These results allowed us to construct an equation that predicted the protein precipitation capacity of the studied hydrolyzable tannins with high accuracy.

RESUMO

Bio- and hydrometallurgical experimental setups at 2-l reactor scale for the processing of fly ash from municipal waste incinerators were explored. We aimed to compare chemical H2SO4 leaching and bioleaching; the latter involved the use of H2SO4 and a mixed culture of acidophilic bacteria. The leaching yields of several elements, including some of those considered as critical (Mg, Co, Ce, Cr, Ga, Nb, Nd, Sb and Sm), are provided. At the end of the experiments, both leaching methods resulted in comparable yields for Mg and Zn (>90%), Al and Mn (>85%), Cr (∼65%), Ga (∼60%), and Ce (∼50%). Chemical leaching showed the best yields for Cu (95%), Fe (91%), and Ni (93%), whereas bioleaching was effective for Nd (76%), Pb (59%), and Co (55%). The two leaching methods generated solids of different quality with respect to the original material as we removed and significantly reduced the metals amounts, and enriched solutions where metals can be recovered for example as mixed salts for further treatment. Compared to chemical leaching the bioleaching halved the use of H2SO4, i.e., a part of agent costs, as a likely consequence of bio-produced acid and improved metal solubility.

RESUMO

The aims of the present study were to (a) evaluate the anthelmintic activity of 10 East African browse plant extracts, (b) examine their role in inhibition of Haemonchus contortus larval exsheathment, (c) establish relationship between inhibition of larval exsheathment and browse plant extract polyphenol composition. Acetone/water (70/30%) extracts of air dried leaves of Acacia etbaica, Cadaba farinosa, Capparis tomentosa, Dichrostachys cinerea, Dodonaea angustifolia, Euclea racemosa, Maerua angolensis, Maytenus senegalensis, Rhus natalensis and Senna singueana were used. The larval exsheathment inhibition assay (LEIA) was applied using H. contortus third stage larvae (L3) and browse plant extract concentrations of 0, 150, 300, 600, 1200µg/ml in phosphate buffered saline (PBS). Data were analysed using the PROC MIXED procedure of SAS. Polyvinylpolypyrrolidone (PVPP) was used to evaluate whether polyphenols were involved in L3 exsheathment inhibition. All browse plant extracts significantly (P≤0.001) inhibited larval exsheathment in a dose dependent manner. The dose required to inhibit 50% of the larvae (EC50) was highest in C. farinosa and lowest in E. racemosa and M. senegalensis. Significant differences (P<0.001) between the control and PVPP treated A. etbaica, C. tomentosa, M. angolensis, R. natalensis and D. cinerea indicates that larval inhibition was largely due to non-phenol compounds. For E. racemosa, M. senegalensis, D. angustifolia and S. singueana, PVPP treatment reversed inhibition activity and in these extracts, inhibition was mostly attributable to tannin and other polyphenols (kaempferol, quercetin and myricetin based glycosides). Overall, the browse plant extracts have anthelmintic property against H. contortus and larval inhibition resulting from the presence of phenolic and non-phenolic compounds.

RESUMO

Tannins have long been considered 'anti-nutritional' factors in monogastric nutrition, shown to reduce feed intake and palatability. However, recent studies revealed that compared with condensed tannins, hydrolysable tannins (HT) appear to have far less impact on growth performance, but may be inhibitory to the total activity of caecal bacteria. This in turn could reduce microbial synthesis of skatole and indole in the hindgut of entire male pigs (EM). Thus, the objective of this study was to determine the impact of a group of dietary HT on growth performance, carcass traits and boar taint compounds of group housed EM. For the study, 36 Swiss Large White boars were assigned within litter to three treatment groups. Boars were offered ad libitum one of three finisher diets supplemented with 0 (C), 15 (T15) or 30 g/kg (T30) of HT from day 105 to 165 of age. Growth performance, carcass characteristics, boar taint compounds in the adipose tissue and cytochrome P450 (CYP) isoenzymes CYP2E1, CYP1A2 and CYP2A19 gene expression in the liver was assessed. Compared with C, feed efficiency but not daily gain and daily feed intake was lower (P<0.05) in T15 and T30 boars. Except for the percentage carcass weight loss during cooling, which tended (P<0.10) to be greater in T30 than C and T15, carcass characteristics were not affected by the diets. In line with the numerically lower androstenone level, bulbourethral and salivary glands of T30 boars were lighter (P<0.05) than of T15 with intermediate values for C. Indole level was lower (P<0.05) in the adipose tissue of T30 than C pigs with intermediate levels in T15. Skatole levels tended (P<0.10) to be lower in T30 and C than T15 pigs. Hepatic gene expression of CYP isoenzymes did not differ between-treatment groups, but was negatively correlated (P<0.05) with androstenone (CYP2E1 and CYP1A2), skatole (CYP2E1, CYP2A) and indole (CYP2A) level. In line with the numerically highest androstenone and skatole concentrations, boar taint odour but not flavour was detected by the panellists in loins from T15 compared with loins from C and T30 boars. These results provide evidence that HT affected metabolism of indolic compounds and androstenone and that they affected the development of accessory sex glands. However, the effects were too small to be detected by sensory evaluation.

RESUMO

OBJECTIVE: We investigated if alexithymia, a personality construct with difficulties in emotional processing, is stable in the general population. METHODS: Altogether 3083 unselected subjects aged 30 and older in Finland completed the 20-item Toronto Alexithymia Scale (TAS-20) in the longitudinal Health 2000 and Health 2011 general population surveys (BRIF8901). The stability of alexithymia at the 11-year follow-up was assessed with t-tests, correlations, and separate linear regression models with base-line and follow-up age, gender, marital status, education, and 12-month depressive and anxiety disorders as confounders. RESULTS: The mean score (SD) of the TAS-20 for the whole sample was 44.2 (10.4) in 2000 and 44.2 (10.9) in 2011 (p=0.731). The mean score of the TAS-20 subscale Difficulty Identifying Feelings increased by 0.3 points, Difficulty Describing Feelings decreased by 0.6 points and Externally Oriented Thinking increased by 0.3 points. The effect sizes of the changes varied from negligible to small. Age had little effect except for the group of the oldest subjects (75-97years): the TAS-20 mean (SD) score was 49.1 (10.1) in 2000 and 53.1 (10.3) in 2011 (p<0.001), the effect size for the increase was medium. TAS-20 score in 2000 explained a significant proportion of variance in TAS-20 score in 2011. Controlling for all baseline confounders improved the model incrementally; the same applied to controlling for confounders at follow-up. Baseline depression or anxiety disorders were not associated with the TAS-20 scores in 2011, whereas current diagnoses were. CONCLUSIONS: According to our large longitudinal study both the absolute and relative stability of alexithymia assessed with the TAS-20 are high in the adult general population.

RESUMO

OBJECTIVE: Temporal stability is a basic assumption underlying any personality trait construct. Previous research on the stability of alexithymia has led to a controversy over whether alexithymia should be viewed as a state-dependent phenomenon or as a stable personality trait. The aim of this 5-year longitudinal study was to examine the temporal stability of alexithymia in the general population in Finland. METHODS: Alexithymia was measured with the 20-Item Toronto Alexithymia Scale (TAS-20) at the baseline and 5 years later. RESULTS: The test-retest correlations of the TAS-20 total and factor-specific scores at the baseline and at the 5-year follow-up ranged from moderate to high in both genders, reflecting a rather high relative stability of the TAS-20 scores over a period of 5 years. CONCLUSIONS: The findings of our study suggest that alexithymia behaves like a stable personality trait in the general population.

RESUMO

The use of synthetic drugs against gastrointestinal nematodes of ruminants has led to a situation where resistance to anthelmintics is widespread, and there is an urgent need for alternative solutions for parasite control. One promising approach is to use polyphenol-rich bioactive plants in animal feeds as natural anthelmintics. In the present work, the in vitro activity of a series of 33 hydrolyzable tannins (HTs) and their hydrolysis product, gallic acid, against egg hatching and motility of L1 and L2 stage Haemonchus contortus larvae was studied. The effect of the selected compounds on egg and larval structure was further studied by scanning electron microscopy. The results indicated clear relationships between HT structure and anthelmintic activity. While HT size, overall flexibility, the types and numbers of functional groups, together with the linkage types between monomeric HTs affected the activity differently, the optimal structure was found with pentagalloylglucose.

RESUMO

Two hundred thirty-seven newly diagnosed yet untreated hypertensive men and women, 35 to 54 years of age, were compared with an age- and gender-stratified random population sample of 146 normotensive men and women to find out whether psychological distress symptoms, anger expression, and alexithymia are associated with elevated blood pressure and whether the possible associations are independent of sodium and alcohol intake, body mass index, and physical fitness. The independent attributes of mean arterial pressure were studied by multivariate regression analyses after combining the subjects in the hypertensive and control groups. Three questionnaires were used: the Brief Symptom Inventory (BSI-37), a 31-item version of the Spielberger State-Trait Anger Expression Inventory (STAXI), and the Toronto Alexithymia Scale (TAS-26). Total scores of the TAS-26 were higher (P<0.001) in hypertensive men and women than in their normotensive control subjects (75.6+/-7.8 vs 64.1+/-9.8 in men and 72.9+/-7.1 vs 57.5+/-11.5 in women). There were no differences between the study and control groups in psychological distress symptoms, including anxiety, depression, and hostility, or in anger expression. In multivariate regression analyses, higher age, male gender, higher sodium intake, lower physical fitness, and alexithymia were independently and highly significantly (P<0.01 for male gender, P<0.0001 for other variables) associated with increased blood pressure, explaining altogether 39.5% of the cross-sectional variation in mean arterial pressure. We conclude that alexithymia, that is, poor ability to experience and express emotions, is associated with elevated blood pressure independent of sodium and alcohol intake, body mass index, and physical fitness.

RESUMO

A 1-year follow-up study of 1756 third- and fifth-grade schoolchildren was conducted with a structured pain questionnaire to assess the prevalence and persistence of self-reported musculoskeletal pain symptoms and disability caused by pain. At follow-up, 1626 (92.7%) children participated in the study. Pain at least once a week persisted in 270 (52.4%) of the 564 children who reported musculoskeletal pain at least once a week in at least one part of the body at baseline. Of the regional pain symptoms, neck pain had highest persistence and, in girls, significantly more than in boys. Persistence of pain was not related to school grade. Widespread pain, determined as in the criteria for fibromyalgia, was found in 132 children (7.5%) and persisted in 35 children (29.7%, 95% CI 21.9-38.4) at follow-up. Disability was more severe in children with pain symptoms in more than one area. This study showed that about half of the preadolescents complaining of musculoskeletal pain at least once a week at baseline had persistent pain symptoms at follow-up. The prognosis of widespread pain in preadolescents was almost the same as the previous findings in adults.

RESUMO

OBJECTIVES: To study the association of musculoskeletal pain with emotional and behavioral problems, especially depressive symptoms in Finnish preadolescents. STUDY DESIGN: A structured pain questionnaire was completed by 1756 third- and fifth-grade schoolchildren for identifying children with widespread pain (WSP), children with neck pain (NP), and pain-free controls for the comparative study. There were 124 children with WSP (mean age, 10.7 years), 108 children with NP (mean age, 11.1 years), and 131 controls (mean age, 10.7 years) who completed the Children's Depression Inventory (CDI) and a sleep questionnaire. A blinded clinical examination was done to detect fibromyalgia. For parental evaluation, the Child Behavior Checklist and a sociodemographic questionnaire were used. For teacher evaluation the Teacher Report Form was used. RESULTS: Children with WSP had significantly higher total emotional and behavioral scores than controls, according to child and parent evaluation. A significant difference in the mean total CDI scores was also found between the WSP and NP groups. Children with fibromyalgia had significantly higher CDI scores than the other children with WSP. CONCLUSIONS: Musculoskeletal pain, especially fibromyalgia, and depressive symptoms had high comorbidity. Pain and depressive symptoms should be recognized to prevent a chronic pain problem.

RESUMO

Psychiatric patients (N = 26) were treated chronically (from 1 week to 12 years) with nitrazepam, because of insomnia. The patients gave their subjective estimations of the effects and side effects of nitrazepam. The concentrations of nitrazepam in the plasma were measured by 63Ni-EC-gas-liquid chromatography. The pharmacokinetics of nitrazepam were compared between the psychiatric patients and healthy volunteers (N = 11). The steady-state concentrations and the half-life of nitrazepam in the psychiatric patients were comparable to those of the healthy volunteers. The subjective hypnotic effect of nitrazepam was mostly good or satisfactory and remained unchanged during long-term treatment. Only a few, mild side effects were reported. Nitrazepam does not seem to cause enzyme induction with lowered plasma levels and may therefore be of special value in the treatment of chronic insomnia.

RESUMO

OBJECTIVE: To compare the results of open and laparoscopic fundoplication. DESIGN: Nonrandomized controlled study with a 3-year follow-up. PATIENTS AND METHODS: Fifty-seven consecutive patients with erosive reflux esophagitis underwent laparoscopic (30 patients) or open (27 patients) fundoplication. INTERVENTIONS: Interview by an independent person. In addition, 52 patients (91%) underwent postoperative endoscopy, and 38 patients (67%) underwent esophageal 24-hour pH recording. RESULTS: Temporary dysphagia was reported by 20 patients (67%) after laparoscopic and by 11 (41%) after open fundoplication (P = .05). There were no differences between groups concerning incidence of persistent dysphagia (20% vs 18%, respectively) and mild to no reflux symptoms (97% vs 100%, respectively). In addition, bloating (50% vs 63%, respectively) and increased flatus (77% vs 78%, respectively) were equally common. Visual analog scale scores for dysphagia, bloating, and increased flatus were 0.6, 2.4, and 4.3, respectively, in the laparoscopic and 0.6, 3.5, and 3.4, respectively, in the open groups. Normal belching ability was reported by 12 patients (40%) after laparoscopic and by 20 (74%) after open fundoplication (P = .01). Visick grade 1 or 2 was reported by 21 patients (70%) after laparoscopic and by 24 (89%) after open fundoplication (P = .08). Defective fundic wrap was detected in 4 patients (13%) in the laparoscopic and in none in the open group. In addition, abnormal results of 24-hour pH recording were found in 4 patients (22%) after laparoscopic and in 2 (10.5%) after open fundoplication. CONCLUSION: From a functional point of view, both techniques were equally effective except concerning belching ability and temporary dysphagia.
