A pilot study investigating the effects of a single dose of a flavonoid-rich blueberry drink on memory in 8-10 year old children

Recent evidence from animal and adult human subjects has demonstrated potential benefits to cognition from flavonoid supplementation. This study aimed to investigate whether these cognitive benefits extended to a sample of school-aged children. Using a cross-over design, with a wash out of at least seven days between drinks, fourteen 8-10 year old children consumed either a flavonoid-rich blueberry drink or matched vehicle. Two hours after consumption, subjects completed a battery of five cognitive tests comprising the Go-NoGo, Stroop, Rey’s Auditory Verbal Learning Task, Object Location Task, and a Visual N-back. In comparison to vehicle, the blueberry drink produced significant improvements in the delayed recall of a previously learned list of words, showing for the first time a cognitive benefit for acute flavonoid intervention in children. However, performance on a measure of proactive interference indicated that the blueberry intervention led to a greater negative impact of previously memorised words on the encoding of a set of new words. There was no benefit of our blueberry intervention for measures of attention, response inhibition or visuo-spatial memory. While findings are mixed, the improvements in delayed recall found in this pilot study suggest that, following acute flavonoid-rich blueberry interventions, school aged children encode memory items more effectively.

Old Tom, new Tom

This presentation will Involve a discussion of Canadian fringe artist Mike Hoolboom's experimental narrative Tom (2002 75 minutes, Digital Video) The presentation will Include a short excerpt and stills from the film Tom is a biography of experimental filmmaker Tom Chomont who tells of his struggle with HIV and Parkinson's disease and disarmingly recounts confronting memories of infanticide, incest, fetishism and death It is how these revelations are innovatively processed through excerpts of Chomont's films, home movies, photos, Images lifted straight form Video Busters, archival and found footage that is so telling it is as If the surface of cinema itself is the body that is being marked and reconstituted and "the personal" forever changed by the Infection of this material Into our psyche.

This work is offered as exemplary evidence of the strong link between an experimental non-narrative cinema that flourishes In North America and new media art

The presentation will touch on the following areas:

> The Innovative marking out of the self In terms relevant to a new media practice.
> The correspondence between this film and media theorist Arthur Kroker's Ideas about panic bodies and excremental culture.
> An examination of erasure and loss In non-narrative forms.
> The historical context of Hoolboom's work as part of a North American experimental tradition and as a shared non-narrative tradition With New Media.

The presentation Will conclude With some comments about the relationship between experimental film and new media In this country and how the failure to Identify this relationship constructively here may have contributed to the current "death of the new" The concept of new media and New Australian Will be contrasted to attain some Insight Into the Ideological underpinnings of "Creative Nation".

Multipurpose disinfecting solutions and their interactions with a silicone hydrogel lens

Purpose: To assess the compatibility of a new silicone hydrogel lens, asmofilcon A (with four multipurpose disinfecting solutions: OPTIFREE RepleniSH, ReNu MultiPlus, Solo-Care Aqua and MeniCare Soft). Ocular responses and subjective responses were monitored with each lens-care system combination.

Methods: The study was conducted as a prospective, bilateral, clinical trial with a single-masked investigator, and randomized cross-over design with four phases, (one for each care system). Each study phase comprised of two consecutive days of lens wear where the lenses were inserted on day 1 directly from the blister-packs and worn for over 8 hr, then inserted on day 2 after overnight disinfection with one of the study lens care systems. Twenty-five adapted soft contact lens wearers who were able to wear their habitual lenses comfortably for more than 12 hr were recruited.

Results: There were statistically significant differences in corneal staining found for all the lens-care systems when comparing the results of day 1 (from the blister pack) with day 2 (following care system use) (P < 0.05). ReNu MultiPlus solution had the highest grade for corneal staining at the 2-hr time point on day 2 which then decreased by 6 hr (P < 0.05). There was no difference between the lens care systems and the rating of subjective comfort over either of the two days. The rating of dryness and burning sensations were only slightly increased at 6 hr for all lens care systems except ReNu MultiPlus where burning was highest on insertion (P < 0.05).

Conclusion: Corneal staining observed in this study does not seem to have been related to the presence of polyhexamethylene biguanide (0.0001% wv) that was present in three of the four care systems. Only one care system (ReNu MultiPlus) demonstrated an associated level of corneal staining that was statistically significant; however, this was not considered to be of clinical relevance. These results suggest that using this novel surface-treated silicone hydrogel lens may result in less lens and lens care-related interactions.

The dark ride : The history of the thematic ride as a unique model for new media and cinematic installation

This research examines the translation of the visual language of cinema into a spatial experience. An investigation into early moving images reveals the role that amusement parks played in exploring narratives using architectural spaces. The exegesis will address the history of entertainments, in particular the ‘dark ride’, which have an emphasis on narrative over and above effect.

Extensive field research was undertaken including historical sites across the east coast of the US, in search of new approaches to new media. Over twenty key popular entertainments were experienced first-hand, from Coney Island’s legendary ‘Spookarama’, to the earliest dark ride in operation, ‘The Old Mill’ at Kennywood in Pittsburgh.

Breaking up of prolonged sitting over three days sustains, but does not enhance, lowering of postprandial plasma glucose and insulin in overweight and obese adults

To compare the cumulative (3-day) effect of prolonged sitting on metabolic responses during a mixed meal tolerance test (MTT), with sitting that is regularly interrupted with brief bouts of light-intensity walking. Overweight/obese adults (n=19) were recruited for a randomized, 3-day, outpatient, cross-over trial involving: (1) 7-h days of uninterrupted sitting (SIT); and (2) 7-h days of sitting with light-intensity activity breaks [BREAKS; 2-min of treadmill walking (3.2 km/h) every 20 min (total: 17 breaks/day)]. On days 1 and 3, participants underwent a MTT (75 g of carbohydrate, 50 g of fat) and the incremental area under the curve (iAUC) was calculated from hourly blood samples. Generalized estimating equation (GEE) models were adjusted for gender, body mass index (BMI), energy intake, treatment order and pre-prandial values to determine effects of time, condition and time × condition. The glucose iAUC was 1.3 ± 0.5 and 1.5 ± 0.5 mmol·h·l(-1) (mean differences ± S.E.M.) higher in SIT compared with BREAKS on days 1 and 3 respectively (condition effect: P=0.001), with no effect of time (P=0.48) or time × condition (P=0.8). The insulin iAUC was also higher on both days in SIT (day 1: ∆151 ± 73, day 3: ∆91 ± 73 pmol·h·l(-1), P=0.01), with no effect of time (P=0.52) or time × condition (P=0.71). There was no between-treatment difference in triglycerides (triacylglycerols) iAUC. There were significant between-condition effects but no temporal change in metabolic responses to MTT, indicating that breaking up of sitting over 3 days sustains, but does not enhance, the lowering of postprandial glucose and insulin.

Gestão do conhecimento: os desafios da implantação de um modelo integrado : o caso ANS

A Gestão do Conhecimento vem adquirindo uma importância notória dentro das organizações, tanto públicas quanto privadas. Suas características e aplicações permeiam as discussões acadêmicas e atingem, de forma reflexiva e inovadora, as práticas de trabalho. Seu foco está na elaboração de processos sistemáticos de captura, organização e armazenamento, análise e compartilhamento do conhecimento organizacional (individual e coletivo) voltados à criação de novos conhecimentos, novos produtos, ou novos processos de trabalho. Pretende-se com este estudo levantar os desafios à implantação de um modelo de Gestão do Conhecimento na Agência Nacional de Saúde Suplementar (ANS), tendo como base o discurso dos principais responsáveis por criar estratégias neste sentido e por conceder os instrumentos necessários à sua implementação. Com fundamento na literatura científica sobre o tema, faz-se uma revisão conceitual de conhecimento e de Gestão do Conhecimento, buscando explicitar suas dimensões que passam pela transversalidade do conhecimento, pela aprendizagem individual e organizacional, pelo compartilhamento do conhecimento e pelos sistemas de informação. Como metodologia, optou-se por realizar uma pesquisa qualitativa do tipo explicativa, desenvolvida por meio de estudo de caso, de forma a aprofundar o entendimento da realidade investigada. Os resultados das entrevistas e da análise documental possibilitaram verificar que a ANS tem adotado algumas práticas isoladas associadas à Gestão do Conhecimento. Constatou-se, no discurso, que existe uma predisposição dos gestores de conseguir maior efetividade em suas ações relativas ao compartilhamento do conhecimento e à implantação de um modelo de Gestão do Conhecimento na ANS. A pesquisa, contudo, revelou uma desarticulação institucional ocasionada por cultura hierarquizada e fragmentada, que se mostra profundamente desfavorável à um ambiente de criação e compartilhamento do conhecimento.

Evaluation of the adverse effects of subcutaneous carprofen over six days in healthy cats

This study evaluated the adverse effects of carprofen in seven healthy cats. Values for CBC, biochemical profiles and platelet aggregation were measured before and at seven days after SID treatment with subcutaneous carprofen: 4 mg/kg (day 1), 2 mg/kg (day 2 and 3) and 1 mg/kg (day 4 and 6) (CG) or 0.35 ml of saline (SG) for six days in a randomized, blinded, cross-over study with a four-week washout period. No treatment was given on day 5. Endoscopy of the GI tract was performed pre-treatment and on day 7 post-treatment. There were no significant changes in hematological profiles, biochemical profiles and endoscopy grading scores within nor between groups, except for lower albumin values at baseline than on day 7 (CG), and globulin and ALP values were higher at baseline than on day 7 in CG and SG. SC administration of carprofen over six days did not cause any adverse effects on gastrointestinal, hematological, or serum biochemical variables. (c) 2008 Elsevier Ltd. All rights reserved.

Comparison of omega-3 fatty acids and sulfasalazine in ulcerative colitis

Fish oil omega-3 fatty acids exert antiinflammatory effects on patients with ulcerative colitis. However, a comparative study in patients with mild to moderate ulcerative colitis receiving only sulfasalazine or omega-3 fatty acids has not been performed. We sought to detect changes in the inflammatory disease activity with the use of either fish oil omega-3 fatty acids or sulfasalazine in patients with ulcerative colitis. Ten patients (five male, five female; mean age = 48 +/- 12 y) with mild to moderate active ulcerative colitis were investigated in a randomized cross-over design. They received either sulfasalazine (2 g/d) or omega-3 fatty acids (5.4 g/d) for 2 mo. Disease activity was assessed by clinical and laboratory indicators, sigmoidoscopy, histology, and whole-body protein turnover (with N-15-glycine). Treatment with w-3 fatty acids resulted in greater disease activity as detected by a significant increase in platelet count, erythrocyte sedimentation rate, C-reactive protein, and total fecal nitrogen excretion. No major changes in protein synthesis and breakdown were observed during either treatment. In conclusion, treatment with sulfasalazine is superior to treatment with omega-3 fatty acids in patients with mild to moderate active ulcerative colitis.

Does supplemental LH changes rate and time to ovulation and embryo yield in Santa Ines ewes treated for superovulation with FSH plus eCG?

O objetivo deste trabalho foi avaliar se a suplementação com LH ao final do tratamento gonadotrófico sincroniza o tempo das ovulações e incrementa a taxa de ovulação e produção de embriões em ovelhas Santa Inês. Vinte programas de superovulação (SOV) foram realizados em delineamento cross-over (intervalo de 60 dias). No D0, um CIDR foi inserido, sendo trocado por um novo sete dias após, quando 37,5µg de d-cloprostenol foram administradas. No D12, iniciou-se o tratamento com 256mg de pFSH em 8 administrações (12/12h). No D14, o CIDR foi retirado, 200UI de eCG e 37,5µg de d-cloprostenol foram administradas. No D15, as ovelhas foram alocadas em um dos dois grupos: Controle (n=10), sem suplementação com LH, e LH (n=10), tratado com 7,5mg de LH, 24h após a remoção do CIDR. Inseminações artificiais (IA) foram realizadas 42 e 48h após a remoção do CIDR. As estruturas ovarianas foram avaliadas por laparoscopia imediatamente antes de cada IA e 5 dias após, quando os embriões foram colhidos. As ovelhas que receberam o LH tiveram maior frequência de ovulações antes de 42h (P=0,05). O tratamento com LH tendeu em incrementar a frequência de CL e diminuir a de folículos anovulatórios (P=0,08). A suplementação com LH incrementou (P=0,05) a frequência de ovelhas com alta resposta superovulatória (≥11 CL; P=0,05). em conclusão, a suplementação com LH incrementou a frequência de ovelhas com alta resposta e ovulações antes de 42h depois da remoção do CIDR, entretanto, não houve sincronia entre as ovulações. A suplementação diminuiu a frequência de folículos anovulatórios, embora a taxa de ovulação e a produção de embriões permaneceram inalteradas.

Effects of timing of induced luteolysis in embryo donor mares on reproductive performance and pregnancy rate in recipient mares

The objective was to evaluate the effects of giving prostaglandin F(2 alpha) (PGF) to donor mares 48 h prior to embryo collection. Non-lactating donor mares (n = 20 estrous cycles in 10 mares), ranging from 2.5 to 10 y of age and 400 to 500 kg of body weight were used from September 2004 to February 2005 in the southern hemisphere (Brazil). Donor mares were randomly assigned in a cross-over design study. During a Treated cycle, 7.5 mg PGF was given 48 h prior to embryo collection, whereas in the Control cycle, 7.5 mg PGF was given at embryo collection. In Treated Cycles, serum progesterone concentrations decreased between the day of PGF treatment and the day of embryo collection (13.9 +/- 5.4 and 0.5 +/- 0.3 ng/mL, respectively; P < 0.05). In Treated versus Control cycles, the interovulatory interval was shorter (14.9 +/- 0.9 vs 17.5 +/- 1.1 d, P < 0.05). However, there was no significant difference between these groups for the interval from PGF to ovulation (average, 9.8 d), embryo recovery rate (average, 75%), embryo quality, uterine protein concentration, and pregnancy rate in recipient mares (average, 87% at 15 d after ovulation, with no pregnancy loss detected by 60 d). In conclusion, giving donor mares PGF 48 h prior to embryo collection reduced the average interovulatory interval by approximately 2.5 d, thereby potentially increasing the numbers of embryos that could be collected during a breeding season, with no deleterious effects on embryo recovery rate, embryo quality, or pregnancy rate in recipient mares.
