Marine Drugs , 2010, DOI: 10.3390/md8102721
Abstract: Neurotoxicity induced in fish by domoic acid (DA) was assessed with respect to occurrence of neurotoxic signs, lethality, and histopathology by light microscopy. Sparus?aurata were exposed to a single dose of DA by intraperitoneal (i.p.) injection of 0, 0.45, 0.9, and 9.0 mg DA kg ?1 bw. Mortality (66.67 ± 16.67%) was only observed in dose of 9.0?mg kg ?1 bw. Signs of neurological toxicity were detected for the doses of 0.9 and 9.0?mg DA kg ?1 bw. Furthermore, the mean concentrations (±SD) of DA detected by HPLC-UV in extracts of brain after exposure to 9.0 mg DA kg ?1 bw were 0.61 ± 0.01, 0.96 ± 0.00, and 0.36 ± 0.01 mg DA kg ?1 tissue at 1, 2, and 4 hours. The lack of major permanent brain damage in S. aurata, and reversibility of neurotoxic signs, suggest that lower susceptibility to DA or neuronal recovery occurs in affected individuals.

Abstract: context: the increase of the gastric volume observed in the gavage feeding is likely to cause consequences to the premature newborn, modifying the respiratory indicators. objective: to investigate the alterations in the cardiorespiratory system of premature newborns submitted to an increase of the gastric volume by gavage feeding, according to four different body positioning methods. methods: the study is a randomized crossover trial using a sample of 16 newborns with gestational age from 31 to 34 weeks and birth weight less or equal to 2.500 g. the newborns were included in the study if they had from 7 to 10 days of life, feeding by orogastric tube, total volume of 150 ml/kg/day and absence of supplemental oxygen-therapy. a different positioning method was used at each gavage (all raised to 30o), or say, right lateral, left lateral, prone and supine positions. the following response variables were considered: respiratory and cardiac frequencies, saturation of oxygen, drawing of intercostals, beating of nasal wing and grunting. these measures were collected in intervals of 2 minutes during 5 minutes after the gavage feeding, during whole period of the gavage feeding, and during 5 minutes before the gavage feeding. results: the mean gestational age was 32 weeks (standard deviation 1.3) and the mean weight of the newborns was 1.722 g (standard deviation 276.3). the newborns presented higher values of the mean respiratory frequency in supine and left lateral body positions. in the right lateral and prone positions, the newborns presented lower mean cardiac frequency. the mean oxygen saturation had the lowest values in the left lateral and supine positions. the right lateral and prone positions presented low frequencies of intercostals drawing, beating of nasal wing and grunting. conclusion: our results indicate that right lateral and prone positions have influence on the cardiorespiratory effect, where left lateral and supine are the positions who presented higher nega

Retrovirology , 2006, DOI: 10.1186/1742-4690-3-54
Abstract: In a cohort of 979 untreated individuals infected with HIV-1 with median follow up 3.2 years and 9,828 CD4 T cell measurements, we analysed common amino acid variations: H43Y, V112F, R136Q, G249D, and H419Y. The rate of CD4 T cell decline before treatment was used as the phenotype. In addition, we extended previous work on the in vitro susceptibility of purified donor CD4 T cells (n = 125) to HIV-1 infection, and on the susceptibility of HeLa cells that were stably transduced with the different TRIM5 variants. Haplotypes were analysed according to the most parsimonious evolutionary structure, where two main human TRIM5α groups can be defined according to the residue at amino acid 136. Humans present both Q136 and R136 at similar frequency, and additional TRIM5α amino acid variants are almost exclusively derived from R136-carrying haplotypes.We observed modest differences in disease progression for evolutionary branches carrying R136-derived haplotypes, and with the non-synonymous polymorphisms G249D and H419Y. In vitro analysis of susceptibility of donor CD4 T cells, and of the various transduced HeLa cell lines supported the absence of significant differential restriction of HIV-1 infection by the various huTRIM5α alleles.Common human variants of TRIM5α have no effect or modest effect on HIV-1 disease progression. These variants occur at sites conserved throughout evolution, and are remote from clusters of positive selection in the primate lineage. The evolutionary value of the substitutions remains unclear.The tripartite motif (TRIM) family is a well conserved family of proteins characterized by a structure comprising a RING domain, one or two B-boxes and a predicted coiled-coil region [1]. In addition, most TRIM proteins have additional C-terminal domains. Members of the TRIM protein family are involved in various cellular processes, including cell proliferation, differentiation, development, oncogenesis and apoptosis (for recent review [2,3]). Some TRIM proteins

Environmental Research Journal , 2012,
Abstract: The oxygen transfer rate and the performance of both a packed reactor with a natural support of Opuntia imbricata represented as (R1) and a reactor without support represented as (R2) were compared in the treatment of municipal wastewater. The results demonstrated that the dissolved oxygen (DO) and oxygen transfer rate (KLa) were affected positively by air flow rate when increased from 0-2 lpm, mainly in R1. COD removal efficiency was affected by decreasing hydraulic retention time from 30-10 h in both reactors, but highly significant in R2. The R1 reactor showed higher COD removal rate than R2, when the Organic Loading Rate (OLR) was increased from 0.44-1.32 kg COD m 3 day 1. Biomass concentration after 100 day of continuous operation was 2.49 and 12.35 g VSS L 1 for R1 and R2, respectively. The higher oxygen transfer rate, concentration of active biomass and performance of R1 were result of a greater specific surface area of Opuntia imbricata.
Experienced Teachers Reflecting on Challenging Situations in School  [PDF]

Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.79136
Abstract: The aim of this study is to develop an understanding of how teachers in a lower secondary school deal with challenging situations in the classroom and whether or not they experience that they can obtain help in coping with these situations. Three teachers with five to nine years of teaching experience took part in semi-structured interviews. Before the interviews and before they started to write log book entries for fourteen days to document and reflect on these situations as they occurred in their work in school, the teachers were told that they were to focus on what they felt were challenging situations in their practice. The study shows that these three teachers have various experiences of what they find is difficult to tackle, and that these situations are related to experiences they have had before they started in their profession, and to their values and beliefs. The study also shows that there are common situations that the three teachers perceive as difficult. It becomes evident from the analysis of the data material that they think that good relations between teacher and pupils and between pupils themselves, thus a trustful learning environment, are a good foundation from which to learn to deal with challenging situations in the classroom. They also agree that sharing experiences and solving problems together helps them to tackle challenging situations in school. The teachers think that their basic teacher education has had little influence on their school practice, and they emphasise that further education taken either on campus or with school as the learning arena helps them in their daily practice when confronted with challenging situations.

Abstract: objective: to validate a portuguese version of the ek scale (egen klassifikation), that was developed in denmark for patients with duchenne muscular dystrophy, and spinal muscular atrophy. methods: an english version of the ek scale was translated into the portuguese language as spoken in brazil. this scale was applied to 26 male patients (mean age = 12.7 ± 4.0 years) with duchenne muscular dystrophy. patients also answered questions of a portuguese version of the barthel index questionnaire, and had their right and left hand grip forces measured with a dynamometer. results: the mean total ek scale score was 8.1 ± 7.3 and the barthel index 54.0 ± 26.2. the mean hand grip force was 12.7 ± 17.2 % predicted for the right hand, and 14.6 ± 19.8 % predicted for the left hand. the ek scale scores showed highly significant statistical correlations with age (r= 0.596, p= 0.0013), right hand grip force (r= -0.556, p= 0.0032), left hand grip force (r= -0.623, p=0.0007), and barthel index (r= -0.928, p < 0.0001). conclusion: this translated portuguese version of the ek scale is an adequate tool to be used for brazilian duchenne muscular dystrophy patients.
A starting point of learning to teach science topics at the primary level - The Teacher Education Programme
CHENG May Hung, May
Asia-Pacific Forum on Science Learning and Teaching , 2001,
Abstract: This paper describes the experience of a group of student-teachers in an initial teacher education programme at the Hong Kong Institute of Education. In preparing the student-teachers to teach science, the programme introduced a module on science teaching that included a discussion of the various approaches to teach science and in particular, teaching science with a constructivist view of learning was discussed. The focus of the study is to look at the development of the student-teachers at three phases: before they took the module on science teaching; after they took the module and after their teaching practice period. The student-teachers were interviewed at the three phases and their views on science teaching; feelings about being a science teacher in school and their own experiences in learning to teach were collected and analysed. Drawing on the findings, the paper concludes with the possible factors that influence the development of the student-teachers as they learn to teach.
