Comparison of the Photosynthetic Yield of Cyanobacteria and Green Algae: Different Methods Give Different Answers

The societal importance of renewable carbon-based commodities and energy carriers has elicited a particular interest for high performance phototrophic microorganisms. Selection of optimal strains is often based on direct comparison under laboratory conditions of maximal growth rate or additional valued features such as lipid content. Instead of reporting growth rate in culture, estimation of photosynthetic efficiency (quantum yield of PSII) by pulse-amplitude modulated (PAM) fluorimetry is an often applied alternative method. Here we compared the quantum yield of PSII and the photonic yield on biomass for the green alga Chlorella sorokiniana 211-8K and the cyanobacterium Synechocystis sp. PCC 6803. Our data demonstrate that the PAM technique inherently underestimates the photosynthetic efficiency of cyanobacteria by rendering a high F0 and a low FM, specifically after the commonly practiced dark pre-incubation before a yield measurement. Yet when comparing the calculated biomass yield on light in continuous culture experiments, we obtained nearly equal values for both species. Using mutants of Synechocystis sp. PCC 6803, we analyzed the factors that compromise its PAM-based quantum yield measurements. We will discuss the role of dark respiratory activity, fluorescence emission from the phycobilisomes, and the Mehler-like reaction. Based on the above observations we recommend that PAM measurements in cyanobacteria are interpreted only qualitatively.
Effects of Fasting on Glucagon-like peptide-1 hormone (GLP-1), and Lipid Profile Indices in Obese and Thin Women

Introduction: Glucagon-like peptide-1 hormone (GLP-1) contributes to the regulation of insulin and glucose concentration. However, the effects of fasting on GLP-1 response in different people has not been determined yet. The aim of the present research was to investigate the effect of fasting on GLP-1 and the lipid profile of obese and thin women.Materials and methods: In this research, 25 obese and thin women whose age ranged from 35 to 45 years were selected through a convenient sampling method and were divided into two groups of obese (n=12, body mass index ˃30 kg/m2) and thin (n=13, body mass index=18-20 kg/m2). GLP-1 in both groups was measured in four phases: 3 days before the beginning of Ramadan, 14 days after the beginning of Ramadan, 28 days after the beginning of Ramadan and 2 weeks after the end of Ramadan. Repeated –measure ANOVA was used to statistically analyse the data. Results: GLP-1 was reduced from phase 1 to 3 of the research. However, it was increased after Ramadan. In the thin group, GLP-1 was increased in 14 days of fasting, but did not show any change at the end of Ramadan, and also two weeks after this month. However, none of these changes were statistically significant. The two groups did not diverge from each other significantly in any of the phases.Conclusion: The present findings showed that fasting has no significant effect on the GLP-1 and lipid profile indices of the obese and thin women.
Effects of arbuscular mycorrhizal fungi and rhizobium on shoot and root growth of chickpea in a calcareous soil.

The beneficial effects of arbuscularmycorrhizal (AM) fungi application for the availability of nutrients and improved plant growth have been demonstrated in various greenhouse and field experiments. A greenhouse experiment was conducted to evaluate the effect of AM fungi and Mesorhizobiumciceri on shoot and root growth in Chickpea as a factorial arranged in completely randomized design (CRD) with three replications in a sterilized calcareous soil. Treatments included four mycorrhizal treatments (Glomusmosseae, G. intraradices, combination of G. mosseae and G. intraradices, and control) and two rhizoiba treatments (Mesorhizobiumciceri (Strain No. IC59) and control). Mycorrhizal treatments significantly increased the shoot and root lengths. All of morphological properties (fresh and dry weights of shoot and root, shoot and root lengths) significantly increased in rhizobial treatment. Co-inoculation treatments of plant with AM fungi and rhizobium significantly increased fresh and dry weights of shoot and root. Generally, inoculation with AM fungi and/or MesorhizobiumCiceri can increase plant growth, synergistically, in the soil of low nutrient conten

Etude des mécanismes de haute pathogénicité des Henipavirus

Les Henipavirus sont des paramyxovirus zoonotiques emergents hautement pathogenes. Ils sont capables d’infecter un large spectre d’hotes incluant notamment la chauve-souris frugivore (reservoir naturel), le porc et l’homme. Etant donne leur tres grande dangerosite et en l’absence de traitements curatifs ou prophylactiques efficaces, ces virus doivent etre manipules dans un laboratoire de classe P4. Dans une premiere partie, nous etudions l’effet de composes glyco-amino-glycanes sur l’infection par les Henipavirus ainsi que leur potentielle application en tant que traitement. Dans une seconde partie, nous nous attachons a comprendre les interactions entre le systeme immunitaire de l’hote et le virus. Afin de mieux comprendre ces interactions, nous avons utilise une approche basee sur l’utilisation de souris deficientes pour certaines voies de l’immunite. En effet, bien que les recepteurs cellulaires au virus (EFN B2 et B3) soient fonctionnels chez la souris, celle-ci est resistante a l’infection par voie intraperitoneale. Nous avons analyse la susceptibilite au virus Nipah (NiV) de souris privees de differentes voies du systeme immunitaire inne et adaptatif. Les resultats obtenus permettent d’envisager certaines lignees de ces souris comme nouveaux modeles animaux pour l’etude de l’immunopathogenese du NiV. Cette etude suggere aussi que le systeme interferon de type I joue un role crucial dans la limitation de la propagation virale vers le cerveau et que les lymphocytes T sont necessaires a la complete elimination du virus. Les macrophages jouent, quant a eux, un role central et indispensable, a l’interface entre systeme inne et adaptatif. Enfin, nous abordons les premices d’un projet visant a identifier les differences d’interactions au niveau moleculaire entre les proteines non-structurales du virus et les proteines du systeme immunitaire inne chez l’Homme et la souris afin de voir s’il se degage des differences d’interactions pouvant expliquer les differences de pathogenie. Ces travaux ont donc permis d’identifier de nouveaux modeles animaux et de mieux caracteriser les interactions entre le pathogene et le systeme immunitaire de l’hote, de l’echelle moleculaire a l’echelle de l’organisme entier. Neanmoins, les mecanismes precis de ces interactions restent a elucider et permettront certainement de mieux comprendre la grande diversite de pathogenie des Henipavirus.
Characterising the MLL complex: epigenetic regulation of Hoxa genes

The Mixed-Lineage Leukaemia (MLL1) protein is a key developmental factor that acts to regulate genes via its histone methyl-transferase activity. This study aimed to examine how MLL1 and its associated complex contribute to gene regulation in a functionally relevant cell background. To assess dynamic processes involved, we developed a haematopoietic Stem Cell (hSC) -based system, in which Hoxa genes are down-regulated in a differentiation- induced manner. I characterised the histone modification distribution on two MLL-target genes showing the largest changes upon differentiation: Hoxa4 and Hoxa5. When active, these genes are associated with a peak of “activating” histone marks (H3K4me3, H3K9ac, H4K16ac) over the transcriptional start site, which are lost when the gene is repressed. This correlated with the recruitment of enzymes that deposit these marks, including components of the MLL complex (MLLC, MLLN and menin) as well as HATs that may be associated with the complex (CBP and MOF). Interestingly, the location of these proteins does not always correlate with the marks they deposit. We show that the dual mark H3K9acS10p is present on active Hoxa4 and Hoxa5 genes, and correlates with the presence of the histone kinase Msk1. We speculate that Msk1 contributes to regulating MLL1 HMT’ase activity on these genes.
Resposta da soja (Glycine max (L.) Merrill) a ação de bioestimulante

Aiming to verify the effect of the bioestimulant, Stimulate ® , applied saw by seed and leaf pulverization, in the culture of the soybean. It behaved an experiment under greenhouse, in vases. Randomized block experimental design was used, with four repetitions. The treatments consisted of the combination of bioestimulant doses: seed application (SA) (0; 3; and 5 mL kg -1 of seeds) in the sowing and leaf spray (LS) (0.0; 0.075; 0.150; and 0.225 mL L -1 ), to the 58 days after the emergency (DAE). Collections of plants were accomplished to the 73 and 129 DAE. For some of the studied variables, in the used doses, there was negative effect in the response of the biostimulant application, for some tested doses. Positives responses were verified for flowers and roots dry mass; root/shoot relation; flowers; beans and grains number; and yield for plant. They stood out the treatments: 0,0 mL 0.5 kg -1 (SA) + 0.150 mL L -1 (LS); 3.0 mL 0.5 kg -1 (SA) + 0.0 mL L -1 (LS); 3.0 mL 0.5 kg -1 (SA) + 0.225 mL L -1 (LS); and 5.0 mL 0.5 kg -1 (SA) + 0.075 mL L -1 (LS).
Aproveitamento por soqueira de cana-de-açúcar de final de safra do nitrogênio da aquamônia-15N e uréia-15N aplicado ao solo em complemento à vinhaça

O aproveitamento por soqueira de cana-de-acucar de final de safra do nitrogenio da aquamonia e da ureia aplicado ao solo foi avaliado pela tecnica isotopica com 15 N. 0 experimento foi conduzido em area comercial de cana da variedade SP 70-1143, primeira soca, no Estado de Sao Paulo. Cada tratamento (aquamonia e ureia) contou com 19 linhas de 10 m de comprimento, com espacamento de 1,4 m entre linhas. Os fertilizantes nitrogenados (90 kg/ha de N) foram aplicados manualmente e enterrados no fundo de sulcos com 15 cm de profundidade, distantes 25 cm dos dois lados da linha de cana, apos aplicacao na superficie do solo de vinhaca na dose de 100 m 3 /ha. Os fertilizantes 15 N foram aplicados em parcelas simples de 2 metros lineares (quatro repeticoes). Os resultados experimentais mostraram que a adubacao com uma ou outra forma de fertilizante nitrogenado nao influiu na produtividade da cana e nao houve diferenca entre as quantidades de nitrogenio derivado dos fertilizantes na parte aerea da cultura (recuperacao de 40% de N-fertilizante) apos 12 meses da adubacao (colheita final). Os resultados de N acumulado na parte aerea, em diferentes estadios de crescimento e na colheita final, indicaram forte evidencia de ocorrencia da fixacao biologica de nitrogenio (FBN), que associada a absorcao de nitrogenio do solo resultou no acumulo de 260 kg/ha de N na parte aerea da cultura, aos doze meses apos a adubacao.
Flutuação populacional do predador Doru luteipes Scudder em plantas de milho

O predador Doru luteipes Scudder (Dermaptera: Forficulidae) tem-se mostrado um inseto com grande potencial no controle biologico de duas das principais pragas do milho, Spodoptera frugiperda (Smith) e Helicoverpa zea (Boddie). Este trabalho teve como objetivo estudar a flutuacao do predador em milho, durante seis anos, em plantios mensais, em Sete Lagoas, MG, Brasil, na Embrapa-CNPMS. Foram amostrados semanalmente 100 cartuchos de milho, anotando-se o numero de posturas, ninfas e adultos do predador. Computou-se tambem a porcentagem de plantas contendo pelo menos um individuo (ninfa ou adulto). A presenca do predador foi generalizada, com tendencia as maiores ocorrencias nos plantios efetuados nos meses mais quentes do ano, que representam as epocas de plantios mais recomendadas para a regiao. Observou-se, em cada 100 plantas amostradas, uma media de 4,11 posturas, 10,65 ninfas e 84,19 adultos. A ocorrencia de plantas com pelo menos uma ninfa ou um adulto do predador foi, em media, de 42,8%, chegando, em algumas epocas de plantio, a 95%. Ao longo do ano, foi observada uma resposta quadratica entre epoca de plantio e a ocorrencia de todas as fases do predador. Entretanto, considerando duas fases distintas da curva ajustada, antes e depois do ponto de minimo, a relacao entre a presenca do predador e os meses de plantio correspondentes foi linear.
Clinical study of anemia in rural school children of Mangalore, Karnataka, India

Background: The study was conducted to know the prevalence of anemia in rural school children located within 15km radius of Yenepoya Medical college hospital, Mangalore and to study the risk factors associated with anemia also to correlate the detection of anemia by clinical examination and by lab estimation of hemoglobin.Methods: A total of 550 children in the age group of 6-15 years were included in this study. Parental informed consent was obtained. A preplanner questionnaire was used to collect the health and socio demographic details. Blood was collected by venepuncture method and haemoglobin was determined by automated sysmex machine. Diagnosis of anemia was made according to WHO cut off value of Hb.Results: Out of 550 children 114(20.6%) were anemic. There was no significant difference between age and sex. Anemia was found to be more prevalent in children with h/o passing worms, undernourished, pica and low socio-economic status. Out of 550 children 174 children had conjunctival pallor on clinical examination. Among that 58 (33.3%) children had anemia on hemoglobin estimation. Majority of the children 116 (66.7%) who had pallor on clinical examination was found as non-anemic on hemoglobin estimation. On kappa co efficient, statistics showed that two examinations to detect anemia was 18.47 %, which indicates poor agreement.Conclusions: The overall prevalence of anemia among rural population is variable depending upon the region. Major factors which influence the prevalence of anemia were nutrition, socioeconomic status, pica and worm infestation. Clinical diagnosis by examination of pallor is poorly correlated by estimation of haemoglobin, hence anemia cannot be diagnosed by detection of pallor alone and it requires lab haemoglobin estimation to prevent wrong diagnosis of anemia.
Broad-Band Visually Evoked Potentials: Re(con)volution in Brain-Computer Interfacing

Brain-Computer Interfaces (BCIs) allow users to control devices and communicate by using brain activity only. BCIs based on broad-band visual stimulation can outperform BCIs using other stimulation paradigms. Visual stimulation with pseudo-random bit-sequences evokes specific Broad-Band Visually Evoked Potentials (BBVEPs) that can be reliably used in BCI for high-speed communication in speller applications. In this study, we report a novel paradigm for a BBVEP-based BCI that utilizes a generative framework to predict responses to broad-band stimulation sequences. In this study we designed a BBVEP-based BCI using modulated Gold codes to mark cells in a visual speller BCI. We defined a linear generative model that decomposes full responses into overlapping single-flash responses. These single-flash responses are used to predict responses to novel stimulation sequences, which in turn serve as templates for classification. The linear generative model explains on average 50% and up to 66% of the variance of responses to both seen and unseen sequences. In an online experiment, 12 participants tested a 6 × 6 matrix speller BCI. On average, an online accuracy of 86% was reached with trial lengths of 3.21 seconds. This corresponds to an Information Transfer Rate of 48 bits per minute (approximately 9 symbols per minute). This study indicates the potential to model and predict responses to broad-band stimulation. These predicted responses are proven to be well-suited as templates for a BBVEP-based BCI, thereby enabling communication and control by brain activity only.
Focal adhesion kinase, a major regulator of oligodendrocyte morphological maturation and myelination

FOCAL ADHESION KINASE, A MAJOR REGULATOR OF OLIGODENDROCYTE MORPHOLOGICAL MATURATION AND MYELINATION By Audrey D. Lafrenaye A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at Virginia Commonwealth University. Virginia Commonwealth University, 2010 Major Director: Babette Fuss, Ph.D., Associate Professor, Department of Anatomy and Neurobiology The formation of the myelin sheath is a crucial step during development because it enables fast and efficient propagation of signals within the limited space of the mammalian central nervous system. During the process of myelination, oligodendrocytes actively interact with the extracellular matrix (ECM). These interactions are considered crucial for proper and timely completion of the myelin sheath. However, the exact regulatory circuits involved in the signaling events that occur between the ECM and oligodendrocytes are currently not fully understood. Therefore, in this dissertation we investigated the role of a known integrator of cell-ECM signaling, namely, focal adhesion kinase (FAK), during oligodendrocyte morphological maturation in vivo and in vitro. Conditional and inducible FAK-knockout mice (Fak: PLP/CreER mice) were generated to observe the effect of FAK loss on myelination in vivo. The role of FAK during post-migratory premyelinating oligodendrocyte morphological maturation was explored in vitro using primary rat oligodendrocyte

How Outpatient Palliative Care Teleconsultation Facilitates Empathic Patient-Professional Relationships: A Qualitative Study

Objective The problems and needs of advanced cancer patients and proxies normally increase as the disease progresses. Home-based advanced cancer patients and their proxies benefit from collaborations between primary care physicians and hospital-based palliative care specialists when confronted with complex problems in the last phase of life. Telemedicine might facilitate direct, patient-centered communication between patients and proxies, primary care physicians, and specialist palliative care teams (SPCTs). This study focuses on the impact of teleconsultation technologies on the relationships between home-based palliative care patients and hospital-based palliative care specialists. Methods This work consists of a qualitative study among patients, family members, and caregivers that utilizes long-term direct observations, semi-structured interviews, and open interviews following the observations. Results The analysis of the empirical data resulted in three key concepts that describe the impact of teleconsultation on the patient-professional relationship in palliative homecare: transcending the institutional walls of home and hospital; transparency of teleconsultation technology; and technologized, intimate patient-professional relationships. Teleconsultation offers (1) condensed encounters between home-based palliative care patients and distant professionals, (2) a unique insight into the patients’ daily lives for palliative care specialists, and (3) long-term interaction that results in trustful relationships and experiences of intimacy and relief. Conclusions Teleconsultation fits the practice of home-based palliative care. Teleconsultation can, if well applied, facilitate computer-mediated but empathic patient-palliative care specialist relationships, which enable professional care attuned to the patient’s context as well as patient involvement. This article proposes a teleconsultation implementation guide for optimal use of teleconsultation in daily palliative care practice.

Bay of Biscay and Ibero Atlantic anchovy populations and their fisheries

SUMMARY: A review is presented about the state of knowledge on the biology, fisheries and population dynamics of the anchovy inhabiting the southern areas of the Atlantic European coasts, from the Bay of Biscay to the Bay of Cadiz. During the current century important and parallel changes in the catches on these coasts have occurred. Those changes and the current knowledge on interactions between the climatic environment and the abundance of the Bay of Biscay anchovy suggest that environment plays a key role in determining the evolution of those populations. Bay of Biscay anchovy is a good example of a small pelagic species: short life span (maximum 3-4 years), seasonal migrations, intense growth, early maturity (at its first birthday), schooling behaviour especially in spring at its spawning time and abundant dependent occupation of its habitat (spawning area expands at high levels of abundance and concentrates at low levels). The large year to year variability in the abundance of the populations, according to the changing recruitment, makes scientific monitoring and advice on the fishery especially difficult. At the moment, no scientific management of these fisheries has been implemented by the EU.
The association between perceived maternal and paternal psychopathology and depression and anxiety symptoms in adolescent girls

Exposure to parental depression and anxiety is known to heighten the risk of internalizing symptoms and disorders in children and adolescents. Ample research has focused on the influence of maternal depression and anxiety, but the contribution of psychopathology in fathers remains unclear. We studied the relationships of perceived maternal and paternal psychopathology with adolescents’ depression and anxiety symptoms in a general population sample of 862 adolescent girls (age M = 12.39, SD = 0.79). Assessments included adolescents’ self-reports of their own depression and anxiety as well as their reports of maternal and paternal psychopathology. We found that perceived maternal and paternal psychopathology were both related to depression and anxiety symptoms in adolescent girls. A combination of higher maternal and paternal psychopathology was related to even higher levels of depression and anxiety in adolescent girls. Our findings showed that adolescents’ perceptions of their parents’ psychopathology are significantly related to their own emotional problems.
