Published: February 2024

Se presenta un estudio piloto para conocer las características psicométricas de un instrumento que evalúa el papel disposicional de algunos elementos de la categoría de Situaciones del análisis microcontingencial, con relación a la regulación del peso corporal. Este instrumento forma parte de una batería de cuatro instrumentos. El modelo que lo sustenta es interconductual y la batería se desarrolló a partir de las categorías del Análisis Contingencial. Se aplicó en línea, una vez que cinco jueces expertos y cinco participantes lo aprobaron, a 196 participantes, 160 mujeres y 36 hombres, cuyas edades fluctuaban entre los 19 y los 68 años y que fueron captados a través de una convocatoria difundida en redes sociales. El análisis estadístico consistió en determinar el poder discriminativo de los reactivos que conformaron el instrumento y luego en realizar un análisis factorial exploratorio. Se obtuvo también la varianza por factor y la varianza total explicada. Para el análisis de consistencia interna del instrumento se calculó el coeficiente de Alfa Cronbach, que obtuvo 0.90. El análisis factorizó el instrumento de un modo que correspondió con lo esperado, en siete factores. Se discuten los hallazgos a la luz de la metodología.

Published: February 2024

Debido a la pandemia del COVID-19 los mandatarios a nivel internacional a través de la administración actuaron de una manera atípica debido a la emergencia sanitaria. Gracias a esta situación, se gestó la contratación de emergencia sanitaria pública en Colombia y España, con el objetivo de recuperar la economía y contener el contagio del virus. En consecuencia, se afectó la reglamentación de la figura normativa del anticipo en España en los contratos celebrados por las instituciones públicas, mientras que en Colombia no se alteró, es por esto que, el presente artículo se realizó por medio del método cualitativo-descriptivo, en el cual se identificaron los cambios sustanciales que sufrieron las normativas, al generar estas contrataciones de emergencia y como establecieron excepciones por los mismos gobiernos como resultado de la aplicación de nuevas normas jurídicas. Por ende, pretendemos dar respuesta a la siguiente pregunta ¿Cuáles fueron los cambios normativos más importantes derivados de la pandemia sobre el anticipo en Colombia y España y su relación con la corrupción? . De acuerdo con el análisis realizado, se toman en cuenta casos de corrupción de la contratación pública y los anticipos, se determinó que el mal manejo de la figura ha desencadenado, varios hechos relevantes donde se produce este fenómeno, sin embargo, no es el generador absoluto de la problemática. En cuanto al comparativo entre los países, se identifica que Colombia utiliza el anticipo con mayor proporción, contrario sensu a lo establecido en España, incluso antes de la pandemia.

Les représentations d’une région française durant l’entre-deux-guerres dans la revue La Bretagne touristique (1922-1939) : quel portrait de pays ?
Authors: Bougeard Christian 
Published: February 2024

La Bretagne touristique, publication mensuelle lancée le 15 avril 1922, devenue Bretagne en 1929, est la création d’un homme Octave-Louis Aubert, journaliste-éditeur installé à SaintBrieuc (Côtes-du-Nord, Bretagne). Par sa revue illustrée d’une riche iconographie dans laquelle la photographie occupe une grande place et au régionalisme revendiqué, Aubert veut promouvoir la Bretagne dans tous les domaines — économiques et touristiques bien sûr, mais surtout littéraires et artistiques —, en défendant les traditions bretonnes tout en associant modernisation et modernité. Des écrivains connus appuient cette initiative. Les reportages photographiques et textuels dressent le portrait d’une région à la forte identité régionale qui s’efforce de préserver sa langue celtique, le breton, ses coutumes et ses traditions en valorisant son patrimoine et son passé, mais qui aspire aussi à se moderniser. En même temps, surtout dans les années 1930, la revue fait connaître les jeunes créateurs bretons (écrivains, poètes, peintres, sculpteurs, graveurs, musiciens) en publiant leurs écrits ou en reproduisant leurs oeuvres. Le dépouillement des 173 numéros parus durant l’entre-deux-guerres montre que La Bretagne touristique forge des représentations du « pays breton », cette « petite patrie » qui veut préserver son identité régionale dans le cadre de la « grande patrie » française, après les sacrifices de la Première Guerre mondiale.

Published: February 2024

Objectives
Anxiety is a disorder with a high prevalence in T2DM, and some studies have found that sleep problems can cause anxiety. Therefore, this study explored the independent effects of night sleep duration on anxiety symptoms in T2DM patients.

Research Design and Methods
A cross-sectional population-based study was conducted using self-reported questionnaires and taking into account several socio-demographic, lifestyle and health related characteristics. The 1,611 participants enrolled in our study. Anxiety was assessed by the Zung self-rating anxiety scale (SAS). A multivariate logistic regression model and restricted cubic spline with anxiety symptoms as the dependent variable were fitted.

Results
Of the T2DM patients in this study, 891 (55.31%) were male, 720 (44.69%) were female and 207 (12.85%) had anxiety symptoms. Controlling for potential confounders and intermediates, sleep duration >8 h relative to intermediate sleep (7–8 h) was significantly associated with anxiety syndrome (OR: 1.46, 95% CI [1.06–2.02], p = 0.02) and a J-shaped association was found between sleep duration and anxiety. The prevalence of anxiety symptoms was higher in the male group (>8 h/night) compared to the female. Study participants under the age of 50 who had a shorter sleep duration had a higher prevalence of anxiety compared to those between the ages of 50 and 60.

Conclusion
Among Chinese T2DM patients, there is a dose-response relationship between night sleep duration and anxiety, these findings may propose important public health implications for diabetes management.
Peptide‐Based Nanotubes and Their Applications in Bionanotechnology
Authors: Gao X. , Matsui H. 
Published: August 2005

AbstractIn nature, biological nanomaterials are synthesized under ambient conditions in a natural microscopic‐sized laboratory, such as a cell. Biological molecules, such as peptides and proteins, undergo self‐assembly processes in vivo and in vitro, and these monomers are assembled into various nanometer‐scale structures at room temperature and atmospheric pressure. The self‐assembled peptide nanostructures can be further organized to form nanowires, nanotubes, and nanoparticles via their molecular‐recognition functions. The application of molecular self‐assemblies of synthetic peptides as nanometer‐scale building blocks in devices is robust, practical, and affordable due to their advantages of reproducibility, large‐scale production ability, monodispersity, and simpler experimental methods. It is also beneficial that smart functionalities can be added at desired positions in peptide nanotubes through well‐established chemical and peptide syntheses. These features of peptide‐based nanotubes are the driving force for investigating and developing peptide nanotube assemblies for biological and non‐biological applications.

Inside Front Cover: Fabrication of Ideally Ordered Nanoporous Alumina Films and Integrated Alumina Nanotubule Arrays by High‐Field Anodization (Adv. Mater. 17/2005)
Authors: Chu S.‐Z. , Wada K. , Inoue S. , Isogai M. , Yasumori A. 
Published: August 2005

AbstractA simple, low‐cost approach to fabricating large‐area highly ordered nanoporous alumina films in sulfuric acid solutions through a single‐step high‐field anodization, without the assistance of any additional process, is reported on p. 2115 by Chu and co‐workers. The critical high anodizing potential in the adopted electrolyte system increases with the ageing of solutions after a long period of anodization. Correspondingly, the applicable current density for stable anodization rises significantly, thus leading to high‐speed film growth. Uniform porous anodic alumina films in sulfuric acid solutions under a high electric field of 40–70  V and 1600–2000  A m–2 are achieved.
Measurement of flow field in biofilm reactors by 3‐D magnetic resonance imaging

Published: August 2005

Abstract3‐D Magnetic resonance imaging (MRI) was used to measure the flow field of water in a packed‐bed column containing Serratia sp. biofilm supported on polyurethane foam, and subsequently to follow a reaction which precipitates lanthanum phosphate on the biofilm. Sensitizing the MR image contrast to the fluid flow along the axis of the bioreactor provided better image‐contrast between the foam and fluid compared to that based on MR signal intensity alone. After reaction, that same “velocity contrast” effectively defined the difference between blocked and unblocked regions by distinguishing between regions of flow and no flow. Data acquired during progressive blockage of reactors challenged at two different flow rates accord with reactor theory; thus, the faster flow rate replenished the reactants uniformly, whereas at the slower flow rate the reactants were concentration limited. MRI velocimetry was used to generate data that can be used to model reactors where the efficiency is progressively compromised by blockage due to precipitation. © 2005 American Institute of Chemical Engineers AIChE J, 2005
Dimensional analysis for planetary mixer: Modified power and Reynolds numbers
Authors: Delaplace G. , Guérin R. , Leuliet J. C. 
Published: August 2005

AbstractMixing times, power consumption, heat transfer, and scale‐up predictions in an agitated vessel require the use of correlations between dimensionless groups such as Prandtl, Nusselt, Power, and Reynolds numbers. These dimensionless numbers are now well established for an agitated vessel equipped with a vertically and centrally mounted impeller in the tank for both Newtonian and non‐Newtonian fluids. To our knowledge, there is more ambiguity as to the definition of the characteristic speed and dimensions, which should be taken into account in the dimensional analysis of planetary mixers. The aim of this paper is twofold: (1) to propose modified Reynolds and Power numbers for planetary mixers and (2) to ascertain the reliability of the modified dimensionless number proposed for a particular planetary mixer, The TRIAXE®, which uses a combination of rotation and gyration of a pitched blade turbine to achieve mixing. The modified Reynolds and Power numbers proposed involve the maximum tip speed as characteristic velocity and are consistent with the definition of traditional Reynolds and Power numbers when only a single revolution around the vertical axis of the mixing device occurs in the vessel, as is the case for a standard mixing system. Experimental power measurements carried out with a planetary mixer when mixing highly viscous Newtonian fluids show that the modified Reynolds and Power numbers proposed succeed in obtaining a unique power curve for the mixing system independently of the speed ratio. This close agreement proves that the modified Reynolds and Power numbers are well adapted for engineering purposes and can be used to compare the power‐consumption performances of planetary mixers with well‐established technologies. © 2005 American Institute of Chemical Engineers AIChE J, 2005
NMR studies on self‐complementary oligonucleotides conjugated with methylene blue
Authors: Jähnchen Judith , Purwanto Maria G. M. , Weisz Klaus 
Published: August 2005

AbstractA carboxyl‐functionalized methylene blue (MB) derivative was synthesized and covalently coupled to three CG‐rich self‐complementary 2′‐deoxyoligonucleotides at their 5′‐end. Thermodynamic and structural details about the interactions between the dye and oligonucleotide duplexes were investigated employing ultraviolet (UV) melting and 1H nuclear magnetic resonance (NMR) experiments. In contrast to previous findings on MB binding, no specific intercalation or binding in the minor or major groove of the double helix was found in a 100 mM NaCl buffer. Rather, proton chemical shift changes in the conjugates provide ample evidence for weak dye–DNA interactions largely through external MB stacking on the terminal base pairs. © 2005 Wiley Periodicals, Inc.

Sentinel lymph node mapping and molecular staging in nonsmall cell lung carcinoma
Authors: Pulte Dianne , Li Eric , Crawford Bernard K. , Newman Elliot , Alexander Alice , Mustalish David C. , Jacobson Daniel R. 
Published: August 2005

AbstractBACKGROUNDLymph node (LN) involvement predicts recurrence in patients who have undergone resection of apparently localized nonsmall cell lung carcinoma (NSCLC). Standard detection methods for LN disease have a low sensitivity, and many patients with apparent N0 disease status develop recurrent disease. Molecular techniques can improve the detection of micrometastases, whereas sentinel lymph node (SLN) mapping can indicate which LN may contain micrometastases. These methods, although potentially complementary, have not, to the authors' knowledge, been used together previously.METHODSThe authors used SLN mapping and molecular staging to improve the detection of LN micrometastases in patients with NSCLC. Reverse transcriptase‐polymerase chain reaction (RT‐PCR) analysis for cytokeratin‐7 (CK7), expressed both in normal lung and in malignant lung, was used to identify tumor‐derived material in LN.RESULTSSLN mapping was performed in 13 patients, with 1–3 SLNs identified in each patient, and sufficient RNA for RT‐PCR was obtained in 12 of these 13 patients. Eleven of 12 tumors expressed CK7. Overall, 32 LNs were positive for CK7, including 13 of 21 SLNs. Ten of 11 patients with evaluable SLNs had at least 1 CK7‐positive SLN. Routine pathology showed Stage I disease in eight patients, T3N0 disease in one patient, and LN‐positive disease in two patients. Of the nine patients with N0 disease according to routine pathology that was evaluable by RT‐PCR, eight patients were upstaged by this technique. All patients with positive LN status by routine pathology who were evaluable by RT‐PCR analysis had positive RT‐PCR results.CONCLUSIONSLN micrometastases were common in resected NSCLC, including patients with N0 disease according to routine pathology. SLN mapping was useful for identifying disease‐containing LNs. This approach may be useful for stratifying histologically N0 patients into higher risk and lower risk groups. Cancer 2005.

AbstractBACKGROUNDThe objective of this study was to define different prognostic groups with regard to locoregional control (LRC) derived from recursive partitioning analysis (RPA).METHODSEight hundred one patients with squamous cell head and neck carcinoma underwent with primary surgery and received postoperative radiotherapy. For the definition of prognostic groups, the method of classification and regression trees was performed, including a large number of well known prognostic factors.RESULTSThe final model was composed of six prognostic factors for LRC, resulting in seven terminal nodes. RPA Class I (intermediate risk) consisted of 381 patients who had no N3 lymph nodes, free surgical margins (> 5 mm), and no extranodal spread (ENS). RPA Class II (high risk) consisted of 189 patients who had 1 positive lymph node with ENS or had T1, T2, or T4 tumors with close or positive surgical margins. RPA Class III (very high risk) consisted of 231 patients who had a N3 neck, ≥ 2 positive lymph nodes with ENS, or a T3 tumor with close or positive surgical margins. The 5‐year LRC rate was 88%, 73% and 58%, in RPA Class I, II, and III, respectively (P < 0.0001). The hazard ratio (HR) relative to RPA Class I was 2.3 (95% confidence interval [95%CI], 1.5–3.6) for RPA Class II and 4.2 (95%CI, 2.8–6.1) for RPA Class III.CONCLUSIONSThe RPA classification scheme studied allowed for the clear definition of three prognostic groups with regard to LRC and OS. These groups may be useful in the design of future prospective, randomized studies investigating new treatment modalities. Cancer 2005. © 2005 American Cancer Society.

AbstractBACKGROUNDThe current study was conducted to test the hypothesis that patterns of failure are correlated with the degree of residual carcinoma after preoperative chemoradiotherapy (CRT) in patients with esophageal carcinoma.METHODSThe authors analyzed the clinical characteristics of patients with carcinoma of the esophagus who underwent preoperative CRT. The residual carcinoma in the resected specimen was categorized into 3 groups (0%, 1–50%, and > 50%). The initial patterns of failure were analyzed according to these categories.RESULTSOf the 235 patients who underwent CRT, 69 (29%) achieved a pathologic complete response (pathCR; Group A), 109 patients (46%) achieved a response but it was less than a pathCR (1–50% residual carcinoma; Group B), and 57 (24%) had no response (> 50% residual carcinoma; Group C). The time to locoregional recurrence was significantly longer for Group A compared with Group C (P = 0.05). The rate of distant metastases was significantly lower in Groups A and B compared with Group C (14% in Group A, 29% in Group B, and 33% in Group C; P = 0.03). The distant metastases‐free survival was found to be significantly longer in Groups A and B compared with Group C (Group A vs. Group B, P = 0.01; Group A vs. Group C, P < 0.0001; and Group B vs. Group C, P = 0.03). A significantly higher proportion of patients in the responding groups (Groups A and B) had no disease recurrence compared with Group C (81% in Group A, 67% in Group B, and 61% in Group C; P = 0.04). The overall survival and disease‐free survival were found to be significantly longer in Groups A and B compared with Group C.CONCLUSIONSData from the current study demonstrate that the proportion of residual carcinoma after preoperative CRT is significantly correlated with patterns of locoregional and distant failure. Future investigations should focus on reducing the proportion of residual carcinoma and metastatic disease progression in patients with esophageal carcinoma.
