This article aims to understand the relationships between small companies and external innovation agents and how they can help strengthening these organisations. A multiple case research method was adopted by the researchers and applied to small companies which presented innovative practices. The data collection included documents, records and interviews with managers/business owners. Such interviews were recorded and coded using the NVivo 10 software. The results showed relationships of trust, ...

Abstract The effects of 1-h anoxia and 3-h recovery periods were assessed on hepatopancreatic glucose metabolism in the crab Neohelice granulata fed on either a carbohydrate-rich (HC) or high-protein (HP) diet. Anoxia increased pyruvate kinase (PK) and hexokinase (HK) activities in HC-fed animals, coinciding with a decrease in glycogen levels. No significant changes occurred in glucose uptake and glycogen synthesis in either dietary group. In HP-fed crabs, HK activity decreased and PK activity was 40% ...

Dynamic cardiomyoplasty is a new surgical procedure proposed for treatment of patients with congestive heart failure.1 Recently, studies have shown improvement in functional class in selected patients after surgery.2 The hemodynamic effects of cardiomyoplasty during exercise have not been documented. We report hemodynamic results in 3 patients during treadmill upright exercise before and after dynamic cardiomyoplasty.

Natural flowering can cause serious scheduling problems in the pineapple (Ananas comosus) industry and increase harvest costs. Pineapple flowering is thought to be triggered by increased ethylene levels and artificial forcing of pineapple flowering is a common practice to promote flowering synchronisation. However, little is known about the early hormonal and molecular changes of pineapple flowering induction and development. Here, we aimed to analyse the molecular, hormonal, and histological changes ...

To compare the autonomic behavior between malnourished children and a control group using analysis of heart rate variability (HRV).Data were analyzed from 70 children who were divided into two groups: malnourished and eutrophic, according to the Z-score nutritional status for height and age. For analysis of HRV indices, heart rate was recorded beat to beat with the child in the supine position for 20min. The analysis of these indices was performed using linear methods, analyzed in the time and frequency ...

Schistosomiasis is an infectious parasitic disease caused by trematodes of the genus Schistosoma, which threatens at least 258 million people worldwide and its control is dependent on a single drug, praziquantel. The aim of this study was to evaluate the anti-Schistosoma mansoni activity in vitro of novel imidazolidine derivatives.We synthesized two novel imidazolidine derivatives: (LPSF/PTS10) (Z)-1-(2-chloro-6-fluorobenzyl)-4-(4-dimethylaminobenzylidene)-5-thioxoimidazolidin-2-one and (LPSF/PTS23) ( ...

The current article assesses the vulnerability of renewable energies in Brazil in the face of climate change, with hydroelectricity and wind power taken as case studies. Future climate data produced by the National Institute for Space Research were employed for three time slices (2010–2040, 2041–2070 and 2071–2100) taken from the Eta 20 km regional model using the global model HadGem2-ES of the IPCC AR5, for scenarios RCP 4.5 and 8.5. Based on these data and using indicators, it was possible to generate ...

The aim of this study is to assess the risk of dynamical diseases in malnourished children. This is achieved by the application of novel chaotic global techniques to the RR-intervals of the electrocardiogram (ECG) in the cohort. Heart Rate Variability (HRV) is an inexpensive and non-invasive tool to measure the autonomic impulses. Here there has been a decrease in chaotic response of HRV. Seventy children were divided into equal groups and the HRV monitored for 20-25 minutes. The Chaos Forward Parameter ( ...

The city of Salvador has the highest prevalence of HTLV-I among blood donors in Brazil. To study the prevalence of HTLV-I among the general population of Salvador, 30 "sentinel surveillance areas" were selected for the investigation of various infectious diseases, and 1385 individuals within these areas were surveyed according to a simple random sample procedure. ELISA was used to screen plasma samples for antibodies to HTLV-I, and the positive samples were tested by a confirmatory assay (Western ...

HCB (hexachlorobenzene) is a ubiquitous pollutant, which is highly toxic to aquatic organisms; however, it is continuously generated and released to the environment. In order to explore the potential of the mussel Perna perna as a sentinel species for monitoring HCB contamination, we have investigated the accumulation and depuration kinetics of 14C-HCB in the mussel exposed to spiked sediment. The sediment, water and mussels were sampled periodically and submitted to solvent extraction for the determination ...

Brazilian green propolis, which is used in food and beverages to improve health and to prevent diseases, demostrates antioxidant, antimutagenic, and antimicrobial activities. Most biological activities are thought to be related to the high levels of drupanin, artepillin C, and baccharin, which are compounds also present in Baccharis dracunculifolia D.C. (Asteraceae). Since propolis chemical composition depends on the region and the period of collection, as well as its plant origin, the effect of ...

South American leaf blight (SALB) of rubber has been the main constraint to production in its neotropical centre of origin since commercial plantations were first established. The fungal causal agent was identified and described more than a century ago but its precise placement within the Ascomycota still remains uncertain. Indeed, such is the ambiguity surrounding the pathogen that each of the spore morphs would, according to their present classification, be placed in different ascomycete families: ...

Paracoccidioidomycosis is a systemic granulomatous disease manifested in the acute/subacute or chronic forms. The anergic cases of the acute/subacute form are most severe, leading to death threatening conditions. Drug treatment is required to control the disease but the response in anergic patients is generally poor. A 15-mer peptide from the major diagnostic antigen gp43, named P10, induces a T-CD4+ helper-1 immune response in mice of different haplotypes and protects against intratracheal challenge ...
