Entrepreneurial Orientation and Dynamic Capabilities

Currently, small and medium enterprises that are family businesses (SMEFs) assume an important role in the global economy. Further, innovation and flexibility became vital to firms’ survival and prosperity in the market during these volatile times. Firms should not only possess critical resources, but also be able to recombine them. Characterized by resource restrictions, SMEFs can rely on dynamic capabilities to access resources and be competitive in the market. In this regard, networking capabilities (NC) and resource combinations (RC) such as exploitative and explorative product development and on market-related capabilities emerge as key dynamic capabilities. This chapter examines the role of Entrepreneurial Orientation (EO) on NC and RC. Using a qualitative method of in-depth case study, the chapter analyzes 12 Portuguese SMEFs.info:eu-repo/semantics/publishedVersio

Carotenoids diet: digestion, gut microbiota modulation, and inflammatory diseases

Several epidemiologic studies have found that consuming fruits and vegetables lowers the risk of getting a variety of chronic illnesses, including several types of cancers, cardiovascular diseases (CVDs), and bowel diseases. Although there is still debate over the bioactive components, various secondary plant metabolites have been linked to these positive health benefits. Many of these features have recently been connected to carotenoids and their metabolites’ effects on intracellular signalling cascades, which influence gene expression and protein translation. Carotenoids are the most prevalent lipid-soluble phytochemicals in the human diet, are found in micromolar amounts in human serum, and are very susceptible to multiple oxidation and isomerisation reactions. The gastrointestinal delivery system, digestion processes, stability, and functionality of carotenoids, as well as their impact on the gut microbiota and how carotenoids may be effective modulators of oxidative stress and inflammatory pathways, are still lacking research advances. Although several pathways involved in carotenoids’ bioactivity have been identified, future studies should focus on the carotenoids’ relationships, related metabolites, and their effects on transcription factors and metabolism.info:eu-repo/semantics/publishedVersio

Tratamento radiocirúrgico de metástases cerebrais: a relação da histologia, localização cerebral e sintomas

Objetivo – Caracterizar clínica e estatisticamente os doentes com metástases cerebrais submetidos a radiocirurgia. Metodologia – Análise retrospetiva dos doentes com metástases cerebrais submetidos a radiocirurgia com Linac no Hospital do Meixoeiro, sendo a informação analisada no SPSS, versão 18. Resultados – Avaliaram‑se 116 doentes com metástases cerebrais. As localizações primárias de pulmão (54,30%) e mama (21,60%) predominaram. Destacaram‑se como sintomas mais frequentes: cefaleias, fraqueza motora, hemiparesia, paresia e tonturas. Confirma‑se a existência de correlação entre os sintomas decorrentes da presença de metástase e a sua localização cerebral, evidenciando a sua importância no diagnóstico precoce das metástases. O lobo frontal foi a localização cerebral predominante. Discussão e Considerações Finais – Verifica‑se que tendencialmente não existe correlação entre a localização primária e a localização cerebral da metástase. O número de metástases tratadas não sugere ter influência no tempo de sobrevida após o seu diagnóstico. A realização de cirurgia e/ou administração de radioterapia holocraniana previamente à radiocirurgia não apresentou prolongamento de sobrevida em comparação com os doentes não submetidos a tratamento prévio. ABSTRACT: Objective – To characterize clinically and statistically patients with brain metastases who underwent radiosurgery. Methodology – Retrospective analysis of patients with brain metastases that underwent linear accelerator‑based radiosurgery in Hospital do Meixoeiro, and the information analyzed in SPSS version 18. Results – Were evaluated 116 patients with brain metastases. Primary tumors of lung (54.30%) and breast (21.60%) were predominant. Symptoms that stood out as common: headache, motor deficit, hemiparesis, paresis and dizziness. It was confirmed the existence of a correlation between the symptoms arising from the presence of metastasis and its brain location, showing its importance in early diagnosis of metastases. The frontal lobe and the parietal lobe represented the most affected locations by brain metastases. Discussion of results and Concluding Remarks – It verified that tends to be no correlation between the primary location of the tumor and the location of brain metastasis. The number of treated metastases didn’t suggest influence on survival after their diagnosis. The realization of surgery and/or administration of whole‑brain irradiation therapy prior to radiosurgery, showed no prolongation of survival compared with patients that were not submitted to previous treatment

1-Hydr­oxy-1,1,3,3,3-penta­phenyl­disiloxane, [Si2O(OH)(Ph)5], at 150 K

In the crystal structure of the title compound, C30H26O2Si2, one Si(Ph)3 residue is bound to another Si(OH)(Ph)2 residue via a nonlinear Si—O—Si bridge. The asymmetric unit is composed of four [Si2O(OH)(Ph)5] molecules. Each pair of adjacent molecules inter­acts via strong and highly directional O—H⋯O hydrogen bonds connecting neighbouring Si—OH units, and via inter-unit O—H⋯π contacts connecting the second hydroxyl groups with adjacent phenyl groups

Estudo da Sensibilização aos Aeroalergenos Phl p 1, Phl p 5, Ole e 1 e Ole e 2 em Doentes com Patologia Alérgica Sazonal

Estudo da Sensibilização aos Aeroalergenos Phl p 1, Phl p 5, Ole e 1 e Ole e 2 em Doentes com Patologia Alérgica Sazonal Cátia Coelho2, Elsa Caeiro2,4, Maria Luísa Lopes1, Ana Filipa Lopes3, Raquel Ferro2, José Eduardo Moreira3, Célia Antunes3,4, Rui Brandão4,5 1Hospital de Santa Luzia, Elvas, Portugal; 2Sociedade Portuguesa de Alergologia e Imunologia Clínica (SPAIC), Lisboa, Portugal; 3Departamento de Química, Universidade de Évora, Portugal; 4Instituto de Ciências Agrárias e Ambientais Mediterrânicas (ICAAM), Universidade de Évora, Portugal; 5 Departamento de Biologia, Universidade de Évora, Portugal Introdução: A sensibilização aos pólenes depende de vários factores nomeadamente do tipo de vegetação local e sabe-se que a sintomatologia não está apenas associada à exposição aos pólens mas também a partículas, algumas das quais resultantes da rotura dos grãos de pólen sendo posteriormente aerossolizadas. Objectivos: Relacionar a sensibilização de doentes com a concentração polínica atmosférica e a concentração de alguns dos respectivos aerolergenos. Métodos: Das consultas externas de Imunoalergologia dos hospitais de Évora e Elvas seleccionaram-se doentes que apresentavam queixas sazonais de rinite alérgica e asma brônquica, aos quais foram realizados testes cutâneos em Prick, standardizados, aos pólenes identificados na região. A 55 doentes foram realizados testes ao extracto de Phleum, aos seus alergénios Phl p 1 e Phl p 5, bem como aos extractos das restantes gramíneas e a 47 doentes foram realizados testes ao extracto de Olea, aos seus alergénios Ole e 1 e Ole e 2. Monitorizaram-se diariamente as partículas polínicas e os aeroalergenos mediante 2 colectores específicos para cada tipo. Resultados: A percentagem de doentes que é sensível aos 3 extractos de Phleum (Phleum total, Phl p 1 e Phl p 5) é de 51% , a dos que são sensíveis aos extractos de Phleum total e Phl p 1 é de 16 % e a dos que são sensíveis a Phleum total e Phl p5 é de 2%. A percentagem de doentes que é sensível a somente um dos extractos é de 20% e os que não têm qualquer sensibilidade são 11%. A percentagem de doentes que é sensível aos 3 extractos de Olea (Olea total, Ole e 1 e Ole e 2) é de 23%, a dos que são sensíveis à Olea total e Ole e 1 é de 21 % e a dos que são sensíveis à Olea total e Ole e 2 é de apenas 4%. A percentagem dos que são sensíveis a um dos extractos é de 19% e a dos que não apresentaram qualquer sensibilidade é de 32%. Conclusões: Podemos concluir que 89% dos doentes mostraram ser sensíveis aos alergénios da gramínea Phleum pratense pois mostraram positividade tanto ao extracto de Phleum e/ou aos seus alergénios Phl p 1 e Phl p 5. Em relação à oliveira, 44% dos doentes são alérgicos a este pólen pois são sensíveis ao seu alergénio major, Ole e 1. Em ambos os casos estão correlacionados com os aeroalergenos detectados nas amostras de ar, sendo a sensibilidade aos pólenes de gramíneas maior que a sensibilidade ao pólen de oliveira. Mais estudos devem ser realizados para despiste de reacções cruzadas nomeadamente quanto à Olea com outras plantas da região

Sheep and goat saliva proteome analysis: A useful tool for ingestive behavior research?

Sheep and goats differ in diet selection, which may reflect different abilities to deal with the ingestion of plant secondary metabolites. Although saliva provides a basis for immediate oral information via sensory cues and also a mechanism for detoxification, our understanding of the role of saliva in the pre-gastric control of the intake of herbivores is rudimentary. Salivary proteins have important biological functions, but despite their significance, their expression patterns in sheep and goats have been little studied. Protein separation techniques coupled to mass spectrometry based techniques have been used to obtain an extensive comprehension of human saliva protein composition but far fewer studies have been undertaken on animals' saliva. We used two-dimensional electrophoresis gel analysis to compare sheep and goats parotid saliva proteome. Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) and liquid chromatography tandem mass spectrometry (LC-MS/MS) were used to identify proteins. From a total of 260 sheep and 205 goat saliva protein spots, 117 and 106 were identified, respectively. A high proportion of serum proteins were found in both salivary protein profiles. Major differences between the two species were detected for proteins within the range of 25–35 kDa. This study presents the parotid saliva proteome of sheep and goat and highlights the potential of proteomics for investigation relating to intake behavior research

Predictors of parent-teacher communication during infant transition to childcare in Portugal

Although literature reports associations between parent-teacher communication and childcare quality, little is known about how such communications are related to family, child and childcare characteristics. This study examines whether child, family and childcare experience characteristics predict the level of parent-teacher communication, and differences between parents’ and teachers’ reports of communication. Participants were mothers of 90 infants and their teachers in childcare in Portugal. Results show that both parents and teachers report higher levels of communication in higher-quality programmes. Teachers reported more frequent communication than parents. Teachers, but not parents, reported more frequent communication when children spent fewer hours in childcare. Discussion highlights the relevance of monitoring the quality of childcare contexts, especially in early ages, and to increase parent-teacher communication when children spend more time in childcare. The importance of promoting high-quality childcare and accounting for variables at the mesosystemic level of development in teacher training are also discussed.info:eu-repo/semantics/publishedVersio
