All-cause mortality and periodontitis in 60-70-year-old men: A prospective cohort study

Objective To investigate the association between periodontitis and mortality from all causes in a prospective study in a homogenous group of 60- to 70-year-old West European men. Methodology A representative sample of 1400 dentate men, (mean age 63.8, SD 3.0 years), drawn from the population of Northern Ireland, had a comprehensive periodontal examination between 2001 and 2003. Men were divided into thirds on the basis of their mean periodontal attachment loss (PAL). The primary endpoint, death from any cause, was analysed using Kaplan-Meier survival plots and Cox's proportional hazards model. Results In total, 152 (10.9%) of the men died during a mean follow-up of 8.9 (SD 0.7) years; 37 (7.9%) men in the third with the lowest PAL (<1.8 mm) died compared with 73 (15.7%) in the third with the highest PAL (>2.6 mm). The unadjusted hazard ratio (HR) for death in the men with the highest level of PAL compared with those with the lowest PAL was 2.11 (95% CI 1.42-3.14), p < 0.0001. After adjustment for confounding variables (age, smoking, hypertension, BMI, diabetes, cholesterol, education, marital status and previous history of a cardiovascular event) the HR was 1.57 (1.04-2.36), p = 0.03. Conclusion The European men in this prospective cohort study with the most severe loss of periodontal attachment were at an increased risk of death compared with those with the lowest loss of periodontal attachment.

Ultrafast low-loss 42-70 GHz differential SPDT switch in 0.35 μm SiGe technology

This paper presents an ultrafast wideband low-loss single-pole double-throw (SPDT) differential switch in 0.35 µ m SiGe bipolar technology. The proposed topology adopting current-steering technique results in a total measured switching time of 75 ps , which suggests a maximum switching rate of 13 Gb/s, the fastest ever reported at V-band. In addition, the switch exhibits an insertion loss lower than 1.25 dB and an isolation higher than 18 dB from 42 GHz to 70 GHz. © 2006 IEEE.

Community-living nonagenarians in northern ireland have lower plasma homocysteine but similar methylenetetrahydrofolate reductase thermolabile genotype prevalence compared to 70-89-year-old subjects

This cross-sectional study assessed relationships between plasma homocysteine, 'thermolabile' methylenetetrahydrofolatereductase (MTHFR) genotype, B vitamin status and measures of renal function in elderly (70-89 years) and nonagenarian (90+ years) subjects, with the hypothesis that octo/nonagenarian subjects who remain healthy into old age as defined by 'Senieur' status might show reduced genetic or environmental risk factors usually associated with hyperhomocysteinaemia. Plasma homocysteine was 9.1 micromol/l (geometric mean [GM]) for all elderly subjects. Intriguingly, homocysteine was significantly lower in 90+ (GM; 8.2 micromol/l) compared to 70-89-year-old subjects (GM; 9.8 micromol/l) despite significantly lower glomerular filtration rate (GFR) and serum B12 in nonagenarian subjects and comparable MTHFR thermolabile (TT) genotype frequency, folate and B6 status to 70-89-year-olds. For all elderly subjects, the odds ratio and 95% confidence intervals for plasma homocysteine being in the highest versus lowest quartile was 4.27 (2.04-8.92) for age 90 years, 3.4 (1.5-7.8) for serum folate 10.7nmol/l, 3.0 (0.9-10.2) for creatinine >140 compared

40-70 GHz 13 Gbps 1-dB loss SPST and SPDT differential switches in 0.35 μm SiGe technology

This paper presents the design and characterization of ultrafast wideband low-loss single-pole single-throw (SPST) and single-pole double-throw (SPDT) differential switches. The SPDT switch exhibits insertion loss of lower than 1.25 dB from 42 to 70 GHz and isolation of better than 20 dB from 40 to 65 GHz. Similar low-loss and broadband characteristics are also observed from the measured SPST switch. The proposed switch topologies adopting current-steering technique and implemented in 0.35 µm SiGe bipolar technology result in a switching time of only 75 ps. This suggests a maximum switching speed of 13 Gbps, the fastest ever reported at V-band.

Desafios da arte contemporânea à conservação e restauro. Documentar a arte Portuguesa dos anos 60/70

A dissertação que aqui se apresenta partiu da necessidade de colocar em confronto as bases éticas da conservação e restauro, que assentam na defesa da materialidade histórica, com a progressiva desmaterialização da arte que ocorre a partir da década de 60 em diante. A organização do trabalho implicou, na escrita, a distinção entre duas partes: uma históricoteórica e a outra de carácter mais prático. Na primeira parte procurámos justificar a progressiva tendência histórica para a desmaterialização do suporte artístico bem como a consequente necessidade de um re-pensamento dos aspectos éticos e práticos da conservação, com particular atenção à documentação do ponto de vista autoral. Na segunda parte da dissertação apresentamos um conjunto de oito casos práticos, a partir de obras de oito artistas portugueses – Henrique Ruivo, Lourdes Castro, Noronha da Costa, Ana Vieira, Alberto Carneiro, João Vieira, René Bertholo e Helena Almeida - todos com início de carreira na década de 60. Procurámos reunir, com base numa investigação em torno dos aspectos da criação da obra, mas também da sua recepção, informação detalhada sobre materiais constitutivos, sua origem e semântica, técnicas, processos criativos, bem como a posição de cada autor relativamente ao envelhecimento das obras em análise. Para o efeito procedemos a um conjunto de entrevistas presenciais aos artistas em questão, directores de museus e curadores – com envolvimento com as obras daqueles - bem como ao levantamento da fortuna crítica associada às obras seleccionadas. Um dos aspectos que se revelou decisivo ao longo do trabalho foi o da investigação dos processos criativos, central para obras cuja autenticidade não se pode resumir a qualquer noção de originalidade material, podendo contudo ser alicerçada na investigação e documentação do processo criativo, realizado essencialmente a partir do ponto de vista autoral. O trabalho efectuado teve também como objectivo a compreensão das condições reais de conservação documental das peças. Concluímos: a necessidade de se proceder à documentação(inscrição) como forma de conservação; o papel imprescindível de uma historiografia da arte mais centrada nos aspectos da preservação; a urgência de formar profissionais preparados para desempenhar esta tarefa; bem como a indispensabilidade de ferramentas que permitam a organização da informação e a sua disponibilização, no âmbito da comunidade envolvida na arte contemporânea, e ao público em geral.

Describe los resultados de los censos gráficos desde 1969/70 hasta 1973/74, en millones de aves. Además menciona, que los principales factores limitantes del normal desarrollo de las poblaciones de aves son el Fenómeno del niño y el volumen del total anual de captura de anchoveta para la industria.

Enhanced expression of 70-kilodalton heat shock protein limits cell division in a sepsis-induced model of acute respiratory distress syndrome.

OBJECTIVE: Fibrotic changes are initiated early in acute respiratory distress syndrome. This may involve overproliferation of alveolar type II cells. In an animal model of acute respiratory distress syndrome, we have shown that the administration of an adenoviral vector overexpressing the 70-kd heat shock protein (AdHSP) limited pathophysiological changes. We hypothesized that this improvement may be modulated, in part, by an early AdHSP-induced attenuation of alveolar type II cell proliferation. DESIGN: Laboratory investigation. SETTING: Hadassah-Hebrew University and University of Pennsylvania animal laboratories. SUBJECTS: Sprague-Dawley Rats (250 g). INTERVENTIONS: Lung injury was induced in male Sprague-Dawley rats via cecal ligation and double puncture. At the time of cecal ligation and double puncture, we injected phosphate-buffered saline, AdHSP, or AdGFP (an adenoviral vector expressing the marker green fluorescent protein) into the trachea. Rats then received subcutaneous bromodeoxyuridine. In separate experiments, A549 cells were incubated with medium, AdHSP, or AdGFP. Some cells were also stimulated with tumor necrosis factor-alpha. After 48 hrs, cytosolic and nuclear proteins from rat lungs or cell cultures were isolated. These were subjected to immunoblotting, immunoprecipitation, electrophoretic mobility shift assay, fluorescent immunohistochemistry, and Northern blot analysis. MEASUREMENTS AND MAIN RESULTS: Alveolar type I cells were lost within 48 hrs of inducing acute respiratory distress syndrome. This was accompanied by alveolar type II cell proliferation. Treatment with AdHSP preserved alveolar type I cells and limited alveolar type II cell proliferation. Heat shock protein 70 prevented overexuberant cell division, in part, by inhibiting hyperphosphorylation of the regulatory retinoblastoma protein. This prevented retinoblastoma protein ubiquitination and degradation and, thus, stabilized the interaction of retinoblastoma protein with E2F1, a key cell division transcription factor. CONCLUSIONS: : Heat shock protein 70-induced attenuation of cell proliferation may be a useful strategy for limiting lung injury when treating acute respiratory distress syndrome if consistent in later time points.
