Differentiation of the Organoleptic Volatile Organic Compound Profile of Three Edible Seaweeds.

The inclusion of seaweeds in daily-consumption food is a worthy-of-attention challenge due to their high nutritional value and potential health benefits. In this way, their composition, organoleptic profile, and toxicity must be assessed. This work focuses on studying the volatile organic compounds (VOCs) emitted by three edible seaweeds, Grateloupia turuturu, Codium tomentosum, and Bifurcaria bifurcata, with the aim of deepening the knowledge regarding their organoleptic profiles. Nine samples of each seaweed were prepared in glass vials, and the emitted headspace was analyzed, for the first time, with a gas chromatography-ion mobility spectrometry device, a highly sensitive technology. By statistically processing the collected data through PCA, it was possible to accurately differentiate the characteristic patterns of the three seaweeds with a total explained variance of 98%. If the data were pre-processed through PLS Regression, the total explained variance increased to 99.36%. The identification of 13 VOCs was accomplished through a developed database of compounds. These outstanding values in addition to the identification of the main emissions of VOCs and the utilization of a never-before-used technology prove the capacity of GC-IMS to differentiate edible seaweeds based solely on their volatile emissions, increase the knowledge regarding their organoleptic profiles, and provide an important step forward in the inclusion of these highly nutritional ingredients in the human diet.

Objective: To analyze the psychometric properties of the SAT-PRO/Br through the observation of structural and concurrent validity, internal consistency and stability. Method: The sample of this cross-sectional study was consecutive, non-probabilistic, consisting of 128 elderly with lower limb amputation, with unilateral amputation and who used the prosthesis for at least one year. The psychometric properties were evaluated through structural validity (Comparative Fit Index- CFI, Tucker-Lewis Index-TLI, Root Means Square Error of Approximation-RMSEA and Standardized Root Mean Residual-SRMR), concurrent validity using the Brazilian version of Trinity Amputation and Prosthesis Experience Scales - Revised (TAPES-R), in addition to the internal consistency of the items by Cronbach's alpha and stability by the Intraclass Correlacion Coefficient (ICC). Results: The SAT-PRO/Br and TAPES-R showed a strong correlation in relation to concurrent validity. Stability ranged from 0.85 to 0.91 across the ICC. The fit model indices showed CFI values of 0.991, TLI of 0.989, RMSEA of 0.045 and SRMR of 0.074. A good internal consistency was observed with a total Cronbach's alpha of 0.91. Conclusion: The psychometric properties of this study on the SAT-PRO/Br lead to the conclusion that this version is valid, reliable and has good internal consistency and stability to be applied to elderly Brazilians with lower limb amputees.

Distribution of the Order Lampriformes in the Mediterranean Sea with Notes on Their Biology, Morphology, and Taxonomy.

Lampriformes are circumglobally distributed and contain several families of strictly marine bony fishes that have a peculiar morphology. Lampriformes systematics is affected by limitations in biometric, meristic, and molecular data; for this reason, it underwent several rearrangements in the past. This review aimed to describe the biological and ecological characteristics of the order Lampriformes, summarizing the current taxonomy of the group. The main aim was to clarify what is known about the distribution of the order Lampriformes in the Mediterranean Sea, collecting all the scarce and fragmented reports and notes on their occurrence. Knowledge scarcity is due to their solitary nature, in addition to their low to absent economic value. Despite this, the order Lampriformes represents a taxon of high biological and ecological importance. The high depth range of distribution characterizes their lifestyle. In the Mediterranean Sea, four families are present-Lampridae, Lophotidae, Regalecidae, and Trachipteridae-with the following species respectively, Lampris guttatus (Brünnich, 1788), Lophotus lacepede (Giorna, 1809), Regalecus glesne (Ascanius, 1772), Trachipterus arcticus (Brünnich, 1788), T. trachypterus (Gmelin, 1789), and Zu cristatus (Bonelli, 1819). Data deficiencies affect information on this taxon; the present review, which collected all the reports of the Mediterranean Sea, creates a baseline for depicting the biogeography of these rare and important species.

Population genomics of introduced Nile tilapia Oreochromis niloticus (Linnaeus, 1758) in the Democratic Republic of the Congo: Repeated introductions since colonial times with multiple sources.

During colonial times, Nile tilapia Oreochromis niloticus (Linnaeus, 1758) was introduced into non-native parts of the Congo Basin (Democratic Republic of the Congo, DRC) for the first time. Currently, it is the most farmed cichlid in the DRC, and is present throughout the Congo Basin. Although Nile tilapia has been reported as an invasive species, documentation of historical introductions into this basin and its consequences are scant. Here, we study the genetic consequences of these introductions by genotyping 213 Nile tilapia from native and introduced regions, focusing on the Congo Basin. Additionally, 48 specimens from 16 other tilapia species were included to test for hybridization. Using RAD sequencing (27,611 single nucleotide polymorphisms), we discovered genetic admixture with other tilapia species in several morphologically identified Nile tilapia from the Congo Basin, reflecting their ability to interbreed and the potential threat they pose to the genetic integrity of native tilapias. Nile tilapia populations from the Upper Congo and those from the Middle-Lower Congo are strongly differentiated. The former show genetic similarity to Nile tilapia from the White Nile, while specimens from the Benue Basin and Lake Kariba are similar to Nile tilapia from the Middle-Lower Congo, suggesting independent introductions using different sources. We conclude that the presence of Nile tilapia in the Congo Basin results from independent introductions, reflecting the dynamic aquaculture history, and that their introduction probably leads to genetic interactions with native tilapias, which could lower their fitness. We therefore urge avoiding further introductions of Nile tilapia in non-native regions and to use native tilapias in future aquaculture efforts.

Expression of the Antimicrobial Peptide Piscidin 1 and Neuropeptides in Fish Gill and Skin: A Potential Participation in Neuro-Immune Interaction.

Antimicrobial peptides (AMPs) are found widespread in nature and possess antimicrobial and immunomodulatory activities. Due to their multifunctional properties, these peptides are a focus of growing body of interest and have been characterized in several fish species. Due to their similarities in amino-acid composition and amphipathic design, it has been suggested that neuropeptides may be directly involved in the innate immune response against pathogen intruders. In this review, we report the molecular characterization of the fish-specific AMP piscidin1, the production of an antibody raised against this peptide and the immunohistochemical identification of this peptide and enkephalins in the neuroepithelial cells (NECs) in the gill of several teleost fish species living in different habitats. In spite of the abundant literature on Piscidin1, the biological role of this peptide in fish visceral organs remains poorly explored, as well as the role of the neuropeptides in neuroimmune interaction in fish. The NECs, by their role as sensors of hypoxia changes in the external environments, in combination with their endocrine nature and secretion of immunomodulatory substances would influence various types of immune cells that contain piscidin, such as mast cells and eosinophils, both showing interaction with the nervous system. The discovery of piscidins in the gill and skin, their diversity and their role in the regulation of immune response will lead to better selection of these immunomodulatory molecules as drug targets to retain antimicrobial barrier function and for aquaculture therapy in the future.

Immunohistochemical and ultrastructural study of the immune cell system and epithelial surfaces of the respiratory organs in the bimodally breathing African sharptooth catfish (Clarias gariepinus Burchell, 1822).

Acetylcholine (Ach) represents the old neurotransmitter in central and peripheral nervous system. Its muscarinic and nicotinic receptors (mAChRs and nAChRs) constitute an independent cholinergic system that is found in immune cells and play a key role in the regulation of the immune function and cytokine production. Gas exchanging surfaces of the gills and air-breathing organs (ABOs) of the sharptooth catfish Clarias gariepinus were investigated using ultrastructural and confocal immunofluorescence techniques. This study was predominantly focused on the structure of the immune cell types, the expression of their neurotransmitters, including the antimicrobial peptide piscidin 1, and the functional significance of respiratory gas exchange epithelia. A network of immune cells (monocytes, eosinophils, and mast cells) was observed in the gill and the ABO epithelia. Eosinophils containing 5-hydroxytryptamine (5-HT) immunoreactivity were seen in close association with mast cells expressing acetylcholine (Ach), 5-HT, neuronal nitric oxide synthase, and piscidin 1. A rich and dense cholinergic innervation dispersing across the islet capillaries of the gas exchange barrier and the localization of Ach in the squamous pavement cells covering the capillaries were evidenced byVAChT antibodies. We report for the first time that piscidin 1 (Pis 1)-positive mast cells interact with Pis 1-positive nerves found in the epithelia of the respiratory organs. Pis 1 immunoreactivity was also observed in the covering respiratory epithelium of the ABOs and associated with a role in local mucosal immune defense. The above results anticipate future studies on the neuro-immune interactions at mucosal barrier surfaces, like the gill and the skin of fish, areas densely populated by different immune cells and sensory nerves that constantly sense and adapt to tissue-specific environmental challenges.

Metabolic and molecular signatures of improved growth in Atlantic salmon (Salmo salar) fed surplus levels of methionine, folic acid, vitamin B6 and B12 throughout smoltification.

A moderate surplus of the one carbon (1C) nutrients methionine, folic acid, vitamin B6 and B12 above dietary recommendations for Atlantic salmon has shown to improve growth and reduce hepatosomatic index in the on-growing saltwater period when fed throughout smoltification. Metabolic properties and molecular mechanisms determining the improved growth are unexplored. Here, we investigate metabolic and transcriptional signatures in skeletal muscle taken before and after smoltification to acquire deeper insight into pathways and possible nutrient­gene interactions. A control feed (Ctrl) or 1C nutrient surplus feed (1C+) were fed to Atlantic salmon 6 weeks prior to smoltification until 3 months after saltwater transfer. Both metabolic and gene expression signatures revealed significant 1C nutrient-dependent changes already at pre-smolt, but differences intensified when analysing post-smolt muscle. Transcriptional differences revealed lower expression of genes related to translation, growth and amino acid metabolisation in post-smolt muscle when fed additional 1C nutrients. The 1C+ group showed less free amino acid and putrescine levels, and higher methionine and glutathione amounts in muscle. For Ctrl muscle, the overall metabolic profile suggests a lower amino acid utilisation for protein synthesis, and increased methionine metabolisation in polyamine and redox homoeostasis, whereas transcription changes are indicative of compensatory growth regulation at local tissue level. These findings point to fine-tuned nutrient­gene interactions fundamental for improved growth capacity through better amino acid utilisation for protein accretion when salmon was fed additional 1C nutrients throughout smoltification. It also highlights potential nutritional programming strategies on improved post-smolt growth through 1C+ supplementation before and throughout smoltification.

Neuroepithelial cells (NECs) and mucous cells express a variety of neurotransmitters and neurotransmitter receptors in the gill and respiratory air-sac of the catfish Heteropneustes fossilis (Siluriformes, Heteropneustidae): a possible role in local immune defence.

Heteropneustes fossilis is an air-breathing teleost inhabiting environments with very poor O2 conditions, and so it has evolved to cope with hypoxia. In the gills and respiratory air-sac, the sites for O2 sensing and the response to hypoxia rely on the expression of acetylcholine (Ach) acting via its nicotinic receptor (nAChR). This study examined the expression patterns of neuronal markers and some compounds in the NECs of the gills and respiratory air sac having an immunomodulatory function in mammalian lungs. Mucous cells, epithelial cells and neuroepithelial cells (NECs) were immunopositive to a variety of both neuronal markers (VAChT, nAChR, GABA-B-R1 receptor, GAD679) and the antimicrobial peptide piscidin, an evolutionary conserved humoral component of the mucosal immune system in fish. We speculate that Ach release via nAChR from mucous cells may be modulated by GABA production in the NECs and it is required for the induction of mucus production in both normoxic and hypoxic conditions. The presence of piscidin in mucous cells may act in synergy with the autocrine/paracrine signals of Ach and GABA binding to GABA B R1B receptor that may play a local immunomodulatory function in the mucous epithelia of the gills and the respiratory air sac. The potential role of the NECs in the immunobiological behaviour of the gill/air-sac is at moment a matter of speculation. The extent to which the NECs as such may participate is elusive at this stage and waits investigation.

Validade e confiabilidade da versão brasileira da Trinity Amputation and Prosthesis Experience Scales - Revised (TAPES-R) / Validity and reliability of the brazilian version of Trinity Amputation and Prosthesis Experience Scales ­ Revised (TAPES-R)

Objetivo: Avaliar a validade e confiabilidade da versão brasileira da TAPES-R em uma população com amputação de membro inferior. Método: Participaram deste estudo transversal 102 pessoas com amputação de membro inferior, usuárias de prótese. Foram avaliadas as propriedades psicométricas (validade concorrente, grau de concordância (Índice de Kappa) e confiabilidade (ICC) intra e interobservador, além da consistência interna dos itens pelo alfa de Cronbach) da versão brasileira da TAPES-R. Para avaliação da validade concorrente foi utilizado o Prosthesis Evaluation Questionnaire (PEQ). Resultados: A TAPES-R se correlacionou com o PEQ, com exceção das subescalas de ajuste social e geral. O ICC interobservador variou de 0,38 a 0,88 na parte 1 e de 0,27 a 0,88 na parte 2, já o ICC intraobservador variou de 0,63 a 0,83 na parte 1 e de 0,27 a 0,79 na parte 2. O índice de Kappa variou de 0,18 a 0,66 na análise interobservador e de 0,25 a 0,69 na análise intraobservador. O Alfa de Cronbach variou de 0,75 a 0,89. Conclusão: A avaliação das propriedades psicométricas permite concluir que a TAPES-R é válida, confiável e apresenta uma boa consistência interna para ser aplicada em adultos brasileiros amputados de membro inferior.

Objective: Evaluate the validity and reliability of the Brazilian version of TAPES-R in people with lower limb amputation. Method: 102 people with lower limb amputation who used a prosthesis participated in this cross-sectional study. The psychometric properties (concurrent validity, degree of agreement (Kappa Index) and intra and interobserver reliability (ICC), in addition to the internal consistency of the items by Cronbach's alpha) of the Brazilian version of TAPES-R were evaluated. To assess concurrent validity, the Prosthesis Evaluation Questionnaire (PEQ) was used. Results: TAPES-R was correlated with PEQ, except for the subscales of social and general adjustment. The inter-observer ICC ranged from 0.38 to 0.88 in part 1 and from 0.27 to 0.88 in part 2, whereas the intra-observer ICC ranged from 0.63 to 0.83 in part 1 and 0.27 to 0.79 in part 2. The Kappa index varied from 0.18 to 0.66 in the inter-observer analysis and from 0.25 to 0.69 in the intra-observer analysis. Cronbach's alpha ranged from 0.75 to 0.89. Conclusion: The evaluation of psychometric properties allows us to verify that a TAPES-R is valid, reliable and has a good internal consistency to be applied to Brazilian adults with lower limb amputations.

Expression of acetylcholine, its contribution to regulation of immune function and O2 sensing and phylogenetic interpretations of the African butterfly fish Pantodon buchholzi (Osteoglossiformes, Pantodontidae).

Acetylcholine (Ach) is the main neurotransmitter in the neuronal cholinergic system and also works as a signaling molecule in non-neuronal cells and tissues. The diversity of signaling pathways mediated by Ach provides a basis for understanding the biology of the cholinergic epithelial cells and immune cells in the gill of the species studied. NECs in the gill were not found surprisingly, but specialized cells showing the morphological, histochemical and ultrastructural characteristics of eosinophils were located in the gill filaments and respiratory lamellae. Much remains unknown about the interaction between the nerves and eosinophils that modulate both the release of acetylcholine and its nicotinic and muscarinic receptors including the role of acetylcholine in the mechanisms of O2 chemosensing. In this study we report for the first time the expression of Ach in the pavement cells of the gill lamellae in fish, the mast cells associated with eosinophils and nerve interaction for both immune cell types, in the gill of the extant butterfly fish Pantodon buchholzi. Multiple roles have been hypothesized for Ach and alpha nAChR in the gills. Among these there are the possible involvement of the pavement cells of the gill lamellae as O2 chemosensitive cells, the interaction of Ach positive mast cells with eosinophils and interaction of eosinophils with nerve terminals. This could be related to the use of the vesicular acetylcholine transporter (VAChT) and the alpha 2 subunit of the acetylcholine nicotinic receptor (alpha 2 nAChR). These data demonstrate the presence of Ach multiple sites of neuronal and non-neuronal release and reception within the gill and its ancestral signaling that arose during the evolutionary history of this conservative fish species.

O índice de validade de conteúdo dos itens variou entre 0,85 e 1, e o índice de validade da escala foi de 0,98. O valor total do coeficiente alfa de Cronbach foi de 0,89. Conclusão: O processo de tradução e adaptação transcultural do SAT-PRO, revelou que este se encontra adaptado à realidade cultural de idosos brasileiros com amputação de membro inferior, apresentando também boa validade de conteúdo e confiabilidade.

The satisfaction of amputees with their prostheses is essential for the success of prosthetic rehabilitation, which justifies the need for instruments to be used by health professionals. One of the instruments that allows this assessment to be carried out is the SAT-PRO questionnaire, developed and applied in Canada, for elderly amputees of lower limb, nevertheless in Brazil it is not yet translated, adapted or validated. Objective: The aim of this study is to carry out the translation of the SAT-PRO into Portuguese and to present a culturally adapted version to be applied to elderly Brazilians. Method: The translation and adaptation were carried out in five stages, followed by a sixth stage, in which the content validation and reliability was verified. Results: During the translation and adaptation process, some ambiguities were found that were overcome by making consensual adjustments to the questionnaire. The content validity index of the items varied between 0.85 and 1 and the scale validity index was 0.98. The total value of Cronbach's alpha coefficient was 0.89. Conclusion: The process of translation and cross-cultural adaptation of the SAT-PRO revealed that it is adapted to the cultural reality of elderly Brazilians with lower limb amputation, also showing good content validity and reliability.

Diazinon negatively affects the integrity of environmental DNA stability: a case study with common carp (Cyprinus carpio).

Environmental DNA (eDNA) has been used to detect the presence of various species in aquatic ecosystems, but its degradation by several environmental factors can influence the correct identification of aquatic organisms. The present study examined the effects of a pesticide, diazinon, on breakage of Cyprinus carpio eDNA. The specimens were exposed to 0 (control), 0.06, 0.1, and 1 ppm of diazinon for 9 days. Water samples were collected at three time points (3, 6, and 9 days postexposure, dpe), and eDNA was extracted. The cytochrome oxidase I (COI) gene was successfully amplified by PCR, and a fuzzy inference system was used to convert DNA smears and breakage to numerical values. eDNA breakage percentage increased with diazinon concentration at all sampling times. At 3 dpe, the maximum eDNA breakage percentage occurred at 0.06 and 0.1 ppm of diazinon; whereas at 6 and 9 dpe, the maximum breakage was found at 1 ppm of diazinon, while exposure time had no significant effect. To the best of our knowledge, this is the first study to demonstrate that eDNA integrity can be compromised by a diazinon in surface waters. Hence, it is recommended that future eDNA studies take into account pesticide pollution when detecting aquatic species.

Microsatellite Analysis of Five Populations of Alosa braschnikowi (Borodin, 1904) Across the Southern Coast of the Caspian Sea.

Genetic diversity studies are essential in characterization of populations and species conservation. Alosa braschnikowi is a commercially valuable species native to the Caspian Sea. It is thought to have eight to nine subspecies, but the genetics of these populations remains to be investigated. The present study was performed to evaluate the genetic population structures of Caspian marine shad (Alosa braschnikowi) in the southern coast of the Caspian Sea using six pairs of SSR markers. A total of Alosa braschnikowi 140 specimens through five locations across the southern coast of the Caspian Sea were genotyped and 130 alleles were identified. The overall mean values of Ho and He were 0.58 and 0.87, respectively, with the highest and minimum value of Ho observed in Sari (0.67 ± 0.08) and Miankaleh (0.50 ± 0.04), respectively. The overall mean value of allelic richness was 12.6. The data suggest that there was a high rate of migration between populations of Alosa braschnikowi (overall mean of Nm = 13.57), with the highest value (19.07) between Gomishan and Mahmodabad locations. AMOVA results showed that 96% of variation was related to within populations and only 4% belonged to between populations. The mean Fst value of 0.019 indicates a low level of population differentiation. Our data suggest that there may be two genetically separate populations of Alosa braschnikowi across the southern coast of the Caspian Sea and a high rate of migration is likely to limit genetic diversity between them.

Psicomotricidade, jogo e corpo-em-relação: contribuições para a intervenção / Psychomotricity, play and body-in-relation: contributions to intervention

Resumo Este ensaio aborda os fundamentos que perspectivam o jogo como mediador da prática psicomotora e a centralidade da dimensão lúdica do corpo-em-relação, enquadrado numa dialética entre o corpo real e o corpo imaginário. Através de uma exposição de ideias, que se fundamentam em diferentes áreas do conhecimento, apresentamos algumas linhas orientadoras para que os profissionais da área da saúde, que pretendem atuar de forma terapêutica ou na ajuda ao desenvolvimento da criança, utilizem o jogo-em-relação. Após breves considerações sobre a psicomotricidade como prática-em-relação, equacionamos a gênese do jogo-em-relação e a sua fundamentação teórico-prática, explicitando a importância das vivências sensoriomotoras (gnosicopráxico) e das representações (imaginário-simbólico) no desenvolvimento psicocorporal e psicomotor da criança. Como considerações finais, veiculamos algumas reflexões necessárias para enquadrar o jogo na intervenção terapêutica, reforçando a importância do estabelecimento de uma relação de qualidade. De forma geral, ao longo do texto, abordamos um conjunto de ideias que permitem aos terapeutas, independentemente de serem psicomotricistas, terapeutas ocupacionais ou outros profissionais, refletir sobre a forma de solicitar a função, a sensorialidade e o imaginário, para favorecerem os processos de integração psíquica, ao utilizarem o jogo-em-relação como mediador da sua intervenção.

Abstract This essay article addresses some fundamentals that look at play as a mediator of psychomotor practice and the centrality of the body-in-relation playful dimension, framed in a dialectic between the real body and the imaginary body. Through an exposition of ideas, which are based on different areas of knowledge, we present some guidelines for health professionals who intend to act in a therapeutic way or assist with child development, using play-in-relation as intervention mediator. After brief considerations about psychomotricity as practice-in-relation, we equate the genesis of play-in-relation and its theoretical-practical grounds, explaining the importance of sensory-motor experiences (perceptive-praxis) and representations (imaginary-symbolic) in the psychocorporeal and psychomotor development of the child. As final considerations, we present some reflections necessary to frame play in therapeutic intervention, reinforcing the importance of establishing a quality relationship. In general, we approach a set of ideas that enables therapists - regardless of whether they are psychomotor therapists, occupational therapists, or others - to reflect on how to request function, sensoriality, and the imaginary to favor the processes of psychic integration, when using play-in-relation as mediator of their intervention.

Transcriptome of Atlantic cod (Gadus morhua L.) early embryos from farmed and wild broodstocks.

Significant efforts have been made to elucidate factors affecting egg quality in fish. Recently, we have shown that eggs originating from wild broodstock (WB) of Atlantic cod (Gadus morhua L.) are of superior quality to those derived from farmed broodstock (FB), and this is associated with differences in the chemical composition of egg yolk. However, maternal transcripts, accumulated during oogenesis, have not been studied extensively in fish. The aim of the present study was to characterize putative maternal mRNA transcriptome in fertilized eggs of Atlantic cod and to compare transcript pools between WB and FB in order to investigate the relation between egg developmental potential and putative maternal mRNA deposits. We performed high-throughput 454 pyrosequencing. For each WB and FB group, five cDNA libraries were individually tagged and sequenced, resulting in 98,687 (WB) and 119,333 (FB) average reads per library. Sequencing reads were de novo assembled, annotated, and mapped. Out of 13,726 identified isotigs, 238 were differentially expressed between WB and FB, with 155 isotigs significantly upregulated in WB. The sequence reads were mapped to 11,340 different Atlantic cod transcripts and 158 sequences were differentially expressed between the 2 groups. Important transcripts involved in fructose metabolism, fatty acid metabolism, glycerophospholipid metabolism, and oxidative phosphorylation were differentially represented between the two broodstock groups, showing potential as biomarkers of egg quality in teleosts. Our findings contribute to the hypothesis that maternal mRNAs affect egg quality and, consequently, the early development of fish.
