From Egg Yolk/κ-Carrageenan dispersions to gel systems: linear viscoelasticity and texture analysis

Versión post-printThe effect of pH (3.5 e 6) and polysaccharide concentration (0 e 0.5 wt%) on the linear viscoelastic behaviour of egg yolk/ k -Carrageenan (EY/ k C) mixtures in aqueous solution was studied by using Small Amplitude Oscillatory Shear (SAOS). Native egg yolk containing 45 wt% solids was used for all the samples. Thermally set EY/ k C gels were also studied by SAOS and texture analysis. A variety of linear viscoelastic behaviours depending on k C concentration and pH were exhibited by EY/ k C dispersions that may be explained in terms of the contributions of electrostatic attractive interactions and an exclusion volume effect between protein and polysaccharide macromolecules. This last effect seems to be domi- nant as pH shifts towards the isoelectric point (IEP) of egg yolk proteins, whereas, at pH far from the IEP a certain enhancement in the degree of compatibility, and even some k C autohydrolysis, seems to take place. The results obtained either from rheological or textural characterization of gels were consistent with that balance. In any case, the results obtained suggest that the microstructure of gels is governed by the protein ability to form gels, where hydrophobically driven interactions and subsequent cross linking among protein segments play a dominant role.MEC/FEDER (Project AGL 2007-65709, Spain) and ME (TME 2008-01144

Knowledge about carbohydrate count and metabolic control in patients with continuous subcutaneous insulin perfusion system

A prevalência da Diabetes Mellitus tipo 1 tem vindo a aumentar nos últimos anos. O tratamento intensivo através de Sistema de Perfusão Subcutânea Contínua de Insulina é o método mais fisiológico de administração de insulina atualmente disponível. Para que este seja eficaz é fundamental ter conhecimentos sobre a composição dos alimentos, particularmente os Hidratos de Carbono. O presente estudo teve como objetivos avaliar e caracterizar o controlo metabólico, compará-lo antes e depois do Sistema de Perfusão Subcutânea Contínua de Insulina, avaliar os conhecimentos de contagem de Hidratos de Carbono e relacioná-los com o controlo metabólico. Trata-se de um estudo observacional, analítico e retrospetivo, com uma amostra de conveniência constituída pelos utentes com consulta entre novembro 2017 e março de 2018 no Hospital Garcia de Orta. A avaliação do controlo metabólico foi realizada através da HbA1c. Na avaliação dos conhecimentos sobre contagem de Hidratos de Carbono utilizou-se uma adaptação do questionário PedCarbQuiz. Avaliaram-se 60 indivíduos com uma média de idades 21,3 ± 14,27 anos [2 - 57]. Aquando a colocação do Sistema de Perfusão Subcutânea Contínua de Insulina, apenas 23,6% da amostra se encontrava com a HbA1c dentro dos valores recomendados. Três meses após a colocação do Sistema de Perfusão Subcutânea Contínua de Insulina verificou-se uma diminuição significativa da HbA1c, que estabilizou após os 6 primeiros meses. Relativamente aos conhecimentos sobre contagem de HC, 78,3% possuíam nível muito bom e os restantes nível bom. Não foi detetada correlação significativa entre a HbA1c e os conhecimentos de contagem de Hidratos de Carbono, ou seja, ter mais conhecimentos não demonstrou ter influência no controlo metabólico da amostra.ABSTRACT - The prevalence of type 1 diabetes mellitus has been increasing in recent years. Intensive treatment through Continuous Subcutaneous Insulin Perfusion System is the most physiological method of insulin administration currently available. For this to be effective it is essential to have knowledge about the composition of the food, particularly about its content in carbohydrates. The aim of the present study was to evaluate and characterize metabolic control, to compare it before and after the Continuous Subcutaneous Insulin Perfusion System, to evaluate the carbohydrates count knowledge and to relate it to metabolic control. This is an observational, analytical and retrospective study, with a convenience sample of patients consulted between November 2017 and March 2018 at the Garcia de Orta Hospital. The evaluation of metabolic control was performed through HbA1c. In the evaluation of the knowledge about carbohydrates count, an adaptation of the PedCarbQuiz questionnaire was used. Sixty individuals with a mean age of 21.3 ± 14.27 years were evaluated [2-57]. At the Subcutaneous Insulin Perfusion System, placement, only 23.6% of the sample was HbA1c within the recommended values. 3 months after Continuous Subcutaneous Insulin Perfusion System placement there was a substantial decrease in HbA1c, which stabilized after the first 6 months. Regarding the knowledge about carbohydrates count, 78.3% had a “very good” level and the remaining “good” level. No significant correlation was detected between HbA1c and carbohydrates counting knowledge. Having more knowledge has not been shown to influence the metabolic control of the sample.info:eu-repo/semantics/publishedVersio

Primary splenic diffuse large B-cell lymphoma: a case report

Primary splenic lymphoma (PSL) is a rare disease and an improbable cause of splenomegaly or splenic nodules. On the contrary, splenic secondary involvement as part of an advanced lymphoproliferative disorder is more common. The authors present the case of a 49-year-old woman with a primary splenic diffuse large B-cell lymphoma (PS-DLBCL), in which the absence of other organs’ involvement determined an ultrasound-guided biopsy of the spleen to achieve a definitive diagnosis. With this case the authors intend to emphasise the extensive differential diagnosis of splenomegaly, splenic nodules or infiltrates, the usefulness of splenic biopsy in establishing the diagnosis and recall a rare disease, with non-specific presenting symptoms, in which the diagnostic workup is challenging

Inferior Vena Cava Syndrome: A Rare Complication

Inferior vena cava syndrome is rare and often difficult to diagnose because of its rarity and consequent low suspicion. We describe the case of a 28-year-old female patient with a history of nephroblastoma of the right kidney, stage IV, with a favourable histology with epidural metastasis (D5-D9), diagnosed at 3 years of age. The patient underwent treatment with surgery, chemotherapy and radiotherapy.The patient suffered from sudden low back pain worsening over 2 weeks, with progressive inability to walk. The pain radiated to the front of the thighs. Concomitantly, oedema of the lower limbs with cephalocaudal progression was observed. At admission to our institution, the physical examination showed peripheral oedema, abdominal wall venous collaterals, an inability to walk due to low back pain in the supine position, with no neurological deficits. Lumbar MRI showed exuberant epidural venous congestion. The hypothesis of inferior vena cava thrombosis (IVCT) was considered and confirmed by angio-CT.IVCT is prevalent in patients with congenital anomalies of the inferior vena cava, occurring in approximately 60–80% of these cases, and most published series on inferior vena cava syndrome refer to thrombotic complications in this subgroup of patients. There are currently no guidelines defined or validated to guide the diagnosis and approach to IVCT. With this case, we would like to draw attention to a rare disease that should be suspected in all patients with inferior vena cava disease, whether resulting from congenital disease or after surgical procedures

Use of Plant-Growth Promoting Rhizobacteria and Mycorrhizal Fungi Consortium as a Strategy to Improve Chickpea (<i>Cicer arietinum</i> L.) Productivity under Different Irrigation Regimes

Climate change prediction indicates an increased likelihood of precipitation variability and droughts in the Mediterranean region. Previous studies demonstrated that microbial symbionts combined with supplementary irrigation could mitigate climate change effects and boost chickpea production in low-fertility soils. The aim of the study was to assess the effects of inoculation with a consortium of plant growth-promoting rhizobacteria (PGPR) (Pseudomonas sp., Burkholderia sp. and Mesorhizobium sp.) and arbuscular mycorrhizal fungi (AMF) (Rhizophagus irregularis, Funneliformis geosporum and Claroideoglomus claroideum) on growth, grain yield and crude protein content of chickpeas under the following irrigation regimes: I1-no water stress, I2-moderate water stress, I3-strong water-stress, I4-no water stress in critical growth stages of plant cycle development and I5-severe water stress). Plants irrigated only during the critical growth stages of flowering and pod filling showed higher grain yields compared to plants from other water deficit irrigation treatments. Additionally, chickpeas co-inoculated with PGPR and AMF, and irrigated only during critical growth stages, presented higher grain yield than non-inoculated plants without water stress (1.45- and 1.33-fold increase in 2018 and 2019, respectively). Inoculation with beneficial microorganisms and supplemental irrigation at critical stages benefits chickpea growth and should be considered for increasing crop productivity and promoting agricultural sustainability

The Condor seamount at Mid-Atlantic Ridge as a supplementary source of trace and rare earth elements to the sediments

14 páginas, 8 figuras, 3 tablasThe Condor Seamount rises from seabed to 180 m water depth, being located 10 nautical miles southwest of the island of Faial, Azores Archipelago at the Mid-Atlantic Ridge (MAR). The vertical distribution of major, minor, trace and rare earth elements (REE) and Pb isotopes was studied in four sediment cores: one from the top of the Condor Seamount (200 m, MC9), two from the seamount base (1400 m, MC2 and MC4), and one from a deep area (1900 m, MC8). Sediments from the top of the Condor were composed by coarser particles being the fine fraction lower than 1%. Conversely the other sediments were constituted by 51–92% of fine particles (2 mm) were found at several depths of the cores sampled at the base of the seamount. The core collected in the top of the Condor showed higher carbonate content (76–86%) compared with the other cores (41–64%). The chemical compositions of MC2 and MC4 point to an enhancement of V, Cr, Co, Ni and Fe concentrations. Lower concentrations in MC8 hypothesis that Condor seamount constitutes a supplementary source of trace elements. The most plausible explanation for the enhancement found in sediments of the seamount base is the weathering of slopes with volcanic activities, which supply particles with higher element concentrations than pelagic sediments. This hypothesis is corroborated by REE data, showing increased chondrite normalized ratios in MC2 and MC4. Moreover, the REE pattern found in those cores was comparable to that existing in volcanic material with Light REE enrichment in comparison to Heavy REE. These results indicate a substantial contribution of particles derived from volcanic activities to sediments settled in the vicinity of the Condor Seamount. It is argued the potential use of REE in sediments from this region as tracers of volcanic activities. Depth profiles of 206Pb/207Pb and 206Pb/208Pb showed lower ratios in the first 8 cm sediment layers, reflecting atmospheric input of anthropogenic Pb in the last century. On the basis of Pb profiles it is proposed a baseline Pb concentration of 3.6±0.2 μg g−1 for pelagic sediments of the region with an isotopic signature of 206Pb/207Pb=1.227±0.003 and 206Pb/208Pb=0.492±0.001 signature. The isotope plots of 206Pb/207Pb versus 208Pb/206Pb showed a linear trend indicating the mixing between more radiogenic pre-industrial end-members and less radiogenic anthropogenic lead. The Pb isotope composition of sediments from the Condor area falls closer to North Atlantic Sediment Line. Sediments showed a 206Pb/204Pb signature closer to the basalts of the Capelo volcanic complex than from Mid-Ocean Ridge Basalts (MORB), which suggests the contribution of similar geological formations to sedimentary material.The current work was supported by a grant from Iceland, Liechtenstein and Norway through the EEA Financial Mechanism — Project CONDOR (PT0040).Peer reviewe

Validação da Subjetive Happiness Scale (SHS) e influência da atividade física sobre a felicidade dos idosos portugueses

This study aimed to validate the Portuguese version of the Subjective Happiness Scale (SHS) for the Portuguese elderly population through a confirmatory factorial analysis, and to verify how subjective happiness differentiates between physically active and inactive elders. Participated in this study 309 elderly (242 women, 67 men), with age between 60 and 90 years old (M= 68.59; SD= 6.60). The results confirmed the good adjustment of the original factorial model: χ² = .26; p= .87; df =2; SRMR = .006; TLI = .98; CFI = .99; RMSEA = .00, allowing us usethe Portuguese version of the Subjective Happiness Scale as instrument of measure the subjective happiness in elderly population. We also verified, through the study of differences, that the active elders have a more perception of happiness compared to the inactive ones.Este estudio tuvo como objetivo validar la versión portuguesa de la Escala de Felicidad Subjetiva (SHS) para la población de portugueses mayores a través de un análisis factorial confirmatorio, y verificar cómo la felicidad subjetiva diferencia entre ancianos físicamente activos e inactivos.
