Nodrizas, madres, médicos: Medicalización de la lactancia en Bogotá 1869-1945

El presente texto realiza un análisis desde la antropología histórica sobre la construcción del concepto de cuerpo de mujer lactante a principios del siglo XX en Colombia. Para esto, se explorara el largo y accidentado proceso en el cual algunos médicos de la época diseñaron saberes (fisiología, bacteriología), herramientas (estadística), leyes y programas sociales (Las gotas de Leche) con la finalidad de convertir la lactancia y el cuerpo de la mujer lactante en un campo exclusivo a la medicina

Prospects for whole genome linkage disequilibrium mapping in domestic dog breeds

Linkage disequilibrium (LD) mapping is commonly used as a fine mapping tool in human genome mapping and has been used with some success for initial disease gene isolation in certain isolated in-bred human populations. An understanding of the population history of domestic dog breeds suggests that LD mapping could be routinely utilized in this species for initial genome-wide scans. Such an approach offers significant advantages over traditional linkage analysis. Here, we demonstrate, using canine copper toxicosis in the Bedlington terrier as the model, that LD mapping could be reasonably expected to be a useful strategy in low-resolution, genome-wide scans in pure-bred dogs. Significant LD was demonstrated over distances up to 33.3 cM. It is very unlikely, for a number of reasons discussed, that this result could be extrapolated to the rest of the genome. It is, however, consistent with the expectation given the population structure of canine breeds and, in this breed at least, with the hypothesis that it may be possible to utilize LD in a genome-wide scan. In this study, LD mapping confirmed the location of the copper toxicosis in Bedlington terrier gene (CT-BT) and was able to do so in a population that was refractory to traditional linkage analysis.

Research and/or learning and teaching : a study of Australian professors' priorities, beliefs and behaviours

This paper presents findings from an empirical study of key aspects of the teaching and research priorities, beliefs and behaviours of 72 professorial and associate professorial academics in Science, Information Technology and Engineering across four faculties in three Australian universities. The academics ranked 16 research activities and 16 matched learning and teaching (L&T) activities from three perspectives: job satisfaction, role model behaviour and perceptions of professional importance. The findings were unequivocally in favour of research in all three areas and remarkably consistent across the universities. The only L&T activity that was ranked consistently well was 'improving student satisfaction ratings for teaching', an area in which academics are increasingly held accountable. Respondents also indicated that their seniors encourage research efforts more than L&T efforts. Recommendations include that higher education rewards for quality L&T are maintained or improved and that recognition of L&T research domains is further strengthened.

Association of a disintegrin and metalloprotease 33 (ADAM33) gene polymorphisms with the risk of COPD: An updated meta-analysis of 2,644 cases and 4,804 controls

A series of observational studies have been made to investigate the association of the ADAM33 gene polymorphisms with the risk of COPD, but their results were conflicting. Therefore, we performed an updated meta-analysis to quantitatively summarize the associations of ADAM33 gene polymorphisms with the risk of COPD. Thirteen case–control studies referring to nine SNPs were identified: V4 (rs2787094), T+1 (rs2280089), T2 (rs2280090), T1 (rs2280091), S2 (rs528557), S1 (rs3918396), Q−1 (rs612709), F+1 (rs511898) and ST+5 (rs597980). A dominant model (AA+Aa vs. aa), recessive model (AA vs. Aa+aa), additive model (AA vs. aa) and allelic model (A vs. a) were used to evaluate the association of ADAM33 polymorphism with the risk of COPD. The results indicated that significant associations were found for ADAM33 T1, T2, S1, Q−1, F+1 and ST+5 polymorphisms associated with the risk of COPD in different populations. However, no significant associations were found for V4, T+1 and S2 polymorphisms with the risk of COPD in all genetic models, even in the subgroup analysis by ethnicity. This meta-analysis provided evidence that the ADAM33 T1, T2, S1, Q−1, F+1 and ST+5 six locus polymorphisms association with the risk of COPD. Furthermore, T2, Q−1 and ST+5 indicated an association with the risk of COPD in the European populations, whereas T1, T2, S1, F+1 and Q−1 indicated an association with the risk of COPD in the Asian populations.

High-level expression of biologically active glycoprotein hormones in Pichia pastoris strains—selection of strain GS115, and not X-33, for the production of biologically active N-glycosylated 15N-labeled phCG

The methylotrophic yeast Pichia pastoris is widely used for the production of recombinant glycoproteins. With the aim to generate biologically active 15N-labeled glycohormones for conformational studies focused on the unravelling of the NMR structures in solution, the P. pastoris strains GS115 and X-33 were explored for the expression of human chorionic gonadotropin (phCG) and human follicle-stimulating hormone (phFSH). In agreement with recent investigations on the N-glycosylation of phCG, produced in P. pastoris GS115, using ammonia/glycerol-methanol as nitrogen/carbon sources, the N-glycosylation pattern of phCG, synthesized using NH4Cl/glucose–glycerol–methanol, comprised neutral and charged, phosphorylated high-mannose-type N-glycans (Man8–15GlcNAc2). However, the changed culturing protocol led to much higher amounts of glycoprotein material, which is of importance for an economical realistic approach of the aimed NMR research. In the context of these studies, attention was also paid to the site specific N-glycosylation in phCG produced in P. pastoris GS115. In contrast to the rather simple N-glycosylation pattern of phCG expressed in the GS115 strain, phCG and phFSH expressed in the X-33 strain revealed, besides neutral high-mannose-type N-glycans, also high concentrations of neutral hypermannose-type N-glycans (Manup-to-30GlcNAc2). The latter finding made the X-33 strain not very suitable for generating 15N-labeled material. Therefore, 15N-phCG was expressed in the GS115 strain using the new optimized protocol. The 15N-enrichment was evaluated by 15N-HSQC NMR spectroscopy and GLC-EI/MS. Circular dichroism studies indicated that 15N-phCG/GS115 had the same folding as urinary hCG. Furthermore, 15N-phCG/GS115 was found to be similar to the unlabeled protein in every respect as judged by radioimmunoassay, radioreceptor assays, and in vitro bioassays.

Open Access to the Scientific Journal Literature: Situation 2009

Background: The Internet has recently made possible the free global availability of scientific journal articles. Open Access (OA) can occur either via OA scientific journals, or via authors posting manuscripts of articles published in subscription journals in open web repositories. So far there have been few systematic studies showing how big the extent of OA is, in particular studies covering all fields of science. Methodology/Principal Findings: The proportion of peer reviewed scholarly journal articles, which are available openly in full text on the web, was studied using a random sample of 1837 titles and a web search engine. Of articles published in 2008, 8,5% were freely available at the publishers’ sites. For an additional 11,9% free manuscript versions could be found using search engines, making the overall OA percentage 20,4%. Chemistry (13%) had the lowest overall share of OA, Earth Sciences (33%) the highest. In medicine, biochemistry and chemistry publishing in OA journals was more common. In all other fields author-posted manuscript copies dominated the picture. Conclusions/Significance: The results show that OA already has a significant positive impact on the availability of the scientific journal literature and that there are big differences between scientific disciplines in the uptake. Due to the lack of awareness of OA-publishing among scientists in most fields outside physics, the results should be of general interest to all scholars. The results should also interest academic publishers, who need to take into account OA in their business strategies and copyright policies, as well as research funders, who like the NIH are starting to require OA availability of results from research projects they fund. The method and search tools developed also offer a good basis for more in-depth studies as well as longitudinal studies.

Studies of phosphazenes. Part 33. Thermal rearrangement of alkoxy(p-methylphenoxy)cyclophosphazenes: a synthetic route to oxocyclophosphazanes, phosphazadienes and phosphaz-1-enes

The aryloxy(alkoxy)cyclotriphosphazenes N3P3(OR)6�m(OC6H4Me-p)n(R = Me, n= 1�3; R = Et or CH2Ph, n= 3) rearrange on heating to give trioxocyclotriphosphazanes; the di- and mono-methoxy derivatives, N3P3(OMe)6�n(OC6H4Me-p)n(n= 4 or 5), yield dioxophosphaz-1-enes and an oxophosphazadiene respectively. The 1H, 13C and 31P NMR data for the starting materials and the products are presented. No evidence has been found for partially rearranged products. The geometrical disposition of the aryloxy groups in the starting material is retained in the rearranged products. Some aspects of the mechanism of the thermal rearrangement are discussed.

Ukrainan vuosien 1932-33 nälänhädän historiapolitiikka

Ukrainan presidentiksi nousi ns. oranssin vallankumouksen nosteessa Viktor Justsenko. Hänen presidenttikaudellaan (2005-2010) vuosien 1932-33 nälänhätä (holodomor) nousi keskeiseksi sekä sisä-, että ulkopolitiikan teemaksi. Holodomor, joka viittaa nälällä aiheutettuun tuhoon, pyrittiin tuomaan osaksi ukrainalaista kollektiivista muistia. Justsenkon aloitteesta säädettiin laki, jonka mukaan holodomor oli ukrainalaisten kansanmurha. Vuosina 1932-33 ympäri Neuvostoliittoa vallitsi nälänhätä. Ukrainalainen maaseutu kärsi pahoin nälänhädän seurauksista, sillä eri arvioiden mukaan 3,5-10 miljoonaa ukrainalaista menehtyi joko suoranaisesti tai välillisesti nälänhädän seurauksena. Ukrainan itsenäistyttyä nälänhätä, jota oli diasporassa alettu kutsua holodomoriksi (nälkätuho), nousi kansallisen historian keskeiseksi teemaksi. Ukrainalainen historioitsija Georgi Kasjanov on nimittänyt tätä uutta vaihetta historian kansallistamiseksi. Tässä työssä pohditaan sitä, miksi holodomor nostettiin keskeiseen asemaan presidentti Viktor Justsenkon valtakaudella. Keskeinen vastakkainasettelun lähtökohta on ollut itsenäisen Ukrainan ja Neuvostoliiton seuraajavaltion Venäjän suhtautuminen nälänhätään 1932-33. Ukrainalaisissa näkökulmissa on painottunut stalinistisen järjestelmän kritiikki, mikä toisaalta on saatettu tulkita myös koko kommunistisen aikakauden tuomitsemiseksi. Venäjällä taas nälänhätä on tulkittu useimmiten yleisneuvostoliittolaiseksi tragediaksi, joka ei kohdistunut erityisesti mitään tiettyä kansallisuutta vastaan. Tutkimuksen keskeinen lähtökohta on tarkastella ukrainalaisten ja venäläisten tulkintojen eroja ja sitä, millä tavoin holodomorilla on tehty politiikkaa. Tutkimusaineistona on käytetty ukrainalaisten osalta presidentti Justsenkon puheita, lakialoitteita ja muita julkilausumia, sekä eräiden yhteiskunnallisten toimijoiden ja historioitsijoiden kannanottoja. Venäläisen osapuolen tulkintoja on pyritty luomaan muutamien tutkimusten ja yhteiskunnallisten toimijoiden, sekä poliitikkojen lausumien pohjalta. Suurin osa aineistosta on kerätty venäjänkielisistä verkkolehdistä. Presidentti Justsenkolle vuosien 1932-1933 historiasta muodostui ase, jolla hän kävi omaa poliittista taisteluaan lännen puolesta itää vastaan. Välit Venäjään olivat viileät koko hänen presidenttikautensa ajan. Lähimmäksi presidentin kantaa holodomor-kysymyksessä tulivat diasporaukrainalaiset. Venäjällä kritisoitiin ankarasti Justsenkon tanssia haudoilla eli hänen tapaansa käyttää nälänhädän uhreja oman politiikkansa välineenä. Venäläiset korostivat nälänhädän tragediaa kaikkien Neuvostoliiton kansojen tragediana. Holodomor oli osa kansallisen historian uudelleenkirjoitusta ja kansakunnan rakentamisen prosessia. Justsenkon päämääränä oli lähentää Ukrainaa länteen, jolloin ukrainalaisen kansakunnan uhriasema antoi oikeutuksen sanoutua irti neuvostoajasta. Tietyssä mielessä holodomor-projekti oli venäläisvastainen, sillä se implisiittisesti tuki käsitystä venäläisistä rikollisina, kansanmurhan toimeenpanijoina.

Ce(0.67)Fe(0.33)O(2-delta) and Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta): New water gas shift (WGS) catalysts

Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta) and Ce(0.67)Fe(0.33)O(2-delta) have been synthesized by a new low temperature sonochemical method using diethylenetriamine as a complexing agent. Due to the substitution of Fe and Pt ions in CeO(2), lattice oxygen is activated in Ce(0.67)Fe(0.33)O(2-delta) and Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta). Hydrogen uptake studies show strong reduction peaks at 125 C in Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta) against a hydrogen uptake peak at 420 degrees C in Ce(0.67)Fe(0.33)O(2-delta). Fe substituted ceria, Ce(0.67)Fe(0.33)O(2-delta) itself acts as a catalyst for CO oxidation and water gas shift (WGS) reactions at moderate temperatures. The rate of CO conversion in WGS with Pt free Ce(0.65)Fe(0.33)O(2-delta) is 2.8 mu mol g(-1) s(-1) at 450 C and with Pt substituted Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta) is 4.05 mu mol g(-1) s(-1) at 275 degrees C. Due to the synergistic interaction of the Pt ion with Ce and Fe ions in Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta), the catalyst showed much higher activity for CO oxidation and WGS reactions compared to Ce(0.67)Fe(0.33)O(2-delta). A reverse WGS reaction does not occur over Ce(0.65)Fe(0.33)Pt(0.02)O(2-delta). The catalyst also does not deactivate even when operated for a long time. Nearly 100% conversion of CO to CO(2) with 100% H(2) selectivity is observed in WGS reactions even up to 550 degrees C. (C) 2011 Elsevier B.V. All rights reserved.

Growth mechanism of ZnO nanostructures for ultra-high piezoelectric d(33) coefficient

A comparative morphological study of different ZnO nanostructures was carried out with different varying process parameters for energy harvesting. Molarity, temperature, growth duration and seed layer were such fundamental controlling parameters. The study brings out an outstanding piezoelectric coefficient (d(33)) of 44.33 pm/V for vertically aligned ZnO nanorod structures, considered as the highest reported d(33) value for any kind of ZnO nanostructures. XRD analysis confirms wurtzite nature of this nanorod structure with 0001] as preferential growth direction. Semiconducting characteristic of nanorods was determined with temperature induced I/V characterization.
