Restauração e conservação: algumas questões para os conservadores. A perspectiva da conservação de têxteis
O texto discute as idéias e diferentes conotações que os conceitos de conservação e restauração trazem em diferentes idiomas e culturas e as possíveis mudanças conceituais ocorridas nos últimos anos. São discutidas as diferenças de abordagem, procedimentos e objetivos que as duas atividades apresentam, sempre do ponto de vista da conservação de têxteis. Vários exemplos de abordagens distintas, desenvolvidas em função dos tratamentos de têxteis de diferentes naturezas são discutidos em detalhe
An evaluation of gender equity in different models of primary care practices in Ontario
Background: The World Health Organization calls for more work evaluating the effect of health care reforms on
gender equity in developed countries. We performed this evaluation in Ontario, Canada where primary care
models resulting from reforms co-exist. // Methods: This cross sectional study of primary care practices uses data collected in 2005-2006. Healthcare service models included in the study consist of fee for service (FFS) based, salaried, and capitation based. We compared the quality of care delivered to women and men in practices of each model. We performed multi-level, multivariate regressions adjusting for patient socio-demographic and economic factors to evaluate vertical equity, and adjusting for these and health factors in evaluating horizontal equity. We measured seven dimensions of health service delivery (e.g. accessibility and continuity) and three dimensions of quality of care using patient surveys (n = 5,361) and chart abstractions (n = 4,108). // Results: Health service delivery measures were comparable in women and men, with differences ≤ 2.2% in all seven dimensions and in all models. Significant gender differences in the health promotion subjects addressed were observed. Female specific preventive manoeuvres were more likely to be performed than other preventive care. Men attending FFS practices were more likely to receive influenza immunization than women (Adjusted odds ratio: 1.75, 95% confidence intervals (CI) 1.05, 2.92). There was no difference in the other three prevention indicators. FFS practices were also more likely to provide recommended care for chronic diseases to men than women (Adjusted difference of -11.2%, CI -21.7, -0.8). A similar trend was observed in Community Health Centers (CHC). // Conclusions: The observed differences in the type of health promotion subjects discussed are likely an appropriate response to the differential healthcare needs between genders. Chronic disease care is non equitable in FFS but not in capitation based models. We recommend that efforts to monitor and address gender based differences in the delivery of chronic disease management in primary care be pursued.Funding for the original study on which this research is based was provided by the Ontario Ministry of Health and Long Term Care Primary Health Care Transition Fund.

Improved trap design for counting migrating fish in rivers
An improved portable trap was designed to capture migrating fishes in rivers prone to severe and rapid fluctuations in water level. The trap was constructed of metal and was assembled on site by three people in 2 h. Its unique design allowed for fast on-site modifications. The trap was tested in a portable weir in a small river in insular Newfoundland. It withstood flood conditions of a magnitude that caused washouts of previously used wooden traps. The overall performance of the metal trap was superior to that of conventional wooden traps. The cost of the metal trap in 1986 was around Can$5,000
The Glu residue in the conserved Asn-Glu-Pro sequence of two highly divergent endo-\u3b2-1,4-glucanases is essential for enzymatic activity
We initially aligned 28 different cellulase sequences in pairwise fashion and found half of them have the sequence -Asn-Glu-Pro- located in a region flanked by hydrophobic-rich amino acids. Based on lysozyme as a model, the glutamate residue could be essential for enzyme function. We tested this possibility by site-directed mutagenesis of the genes coding Bacillus polymyxa and Bacillus subtilis endo-\u3b2-1,4-glucanases. The genes and amino acid sequences of these two enzymes show very little similarity. Change of Glu-194 and Glu-169 to the isosteric glutamine form in these respective enzymes resulted in a dramatic loss of CMCase activity which could be restored by reverse mutation. Similar mutations to less-conserved residues, Glu-72 and Glu-147, of the B. subtilis enzyme did not cause any loss of activity.NRC publication: Ye

Antibody light chain variable domains and their biophysically improved versions for human immunotherapy
We set out to gain deeper insight into the potential of antibody light chain variable domains (VLs) as immunotherapeutics. To this end, we generated a na\uefve human VL phage display library and, by using a method previously shown to select for non-aggregating antibody heavy chain variable domains (VHs), we isolated a diversity of VL domains by panning the library against B cell super-antigen protein L. Eight domains representing different germline origins were shown to be non-aggregating at concentrations as high as 450 \u3bcM, indicating VL repertoires are a rich source of nonaggregating domains. In addition, the VLs demonstrated high expression yields in E. coli, protein L binding and high reversibility of thermal unfolding. A side-by-side comparison with a set of non-aggregating human VHs revealed that the VLs had similar overall profiles with respect to melting temperature (Tm), reversibility of thermal unfolding and resistance to gastrointestinal proteases. Successful engineering of a non-canonical disulfide linkage in the core of VLs did not compromise the non-aggregation state or protein L binding properties. Furthermore, the introduced disulfide bond significantly increased their Tms, by 5.5-17.5 \ub0C, and pepsin resistance, although it somewhat reduced expression yields and subtly changed the structure of VLs. Human VLs and engineered versions may make suitable therapeutics due to their desirable biophysical features. The disulfide linkage-engineered VLs may be the preferred therapeutic format because of their higher stability, especially for oral therapy applications that necessitate high resistance to the stomach's acidic pH and pepsin. \ua9 2014 Landes Bioscience.Peer reviewed: YesNRC publication: Ye
Oocyte development and maturity classification of boarfish (Capros aper) in the Northeast Atlantic
This study presents the first detailed investigation of the oocyte development and maturity classification of boarfish, Capros aper, which has recently become the target of an industrial fishery in the Northeast Atlantic. A total of 2014 boarfish were collected from January to December 2010. Mature male and female boarfish were sexually dimorphic and could be readily identified based on external characteristics. A comprehensive maturity scale was developed, which indicated that the length at 50% maturity for males and females was 9.7 cm total length. Female boarfish were observed to spawn in Irish waters in June and July. Once spawning ceased the remaining mature oocytes were resorbed. Preliminary analysis of reproductive strategy indicates that the boarfish is likely an asynchronous batch spawner with indeterminate fecundity
