Published: July 2019

Aim: Although there are many materials that can be used for retrograde filling in surgical endodontics, none of them can be regarded as an ideal material yet. The purpose of this study was to compare the surface topography of three different root-end filling materials.Methods: 36 extracted single rooted human incisor teeth were cleaned and decoronated to standardized 10 mm root lengths. The root segments were prepared and 2 mm apical resection were performed. The samples were randomly separeted to three groups (Group A: Ca(OH)2, Group B: MTA Angelus, Group C: ProRoot MTA), each comprised of 12 roots. Materials were placed as 2 mm apical barriers and obturated with guttapercha and AH-Plus sealer. Each group dimidiated two subgroups (A1,A2,B1,B2,C1,C2). Groups A1,B1,C1 were stored in normal saline (NS), groups A2,B2,C2 were stored in neutral phosphate buffer saline (NPBS) solution and samples were incubated at 370C for 2 weeks. Stereomicroscope (32X) was used to photograph the root-end filling.Results: All specimens demonstrated white crystals formation and sediment over the root-end filling materials and on the superficial border of the root-end cavities’ wall as a white plague. A2,B2,C2 samples have more crystal sediment on root-end fillings than samples A1,B1,C1. Dissolution and corrosion were observed in groups A1, A2.Conclusions: The results of this study revealed that calcium hydroxide is more resorbable than MTA Angelus and ProRoot MTA. The crystals formation and precipitation were observed in neutral phosphate buffer saline solution was more than normal saline solution for all groups as a hydroxiapatite crystals.

Clay figurines caches found underwater: a phoenician ex voto practice?
Authors: Artzy Michal , Sheizaf Noa
Published: July 2019

In this study results of two underwater excavations in the Eastern Mediterranean, namely in the vicinity of Shavei Zyyon (Linder 1973:182-187) and Tyre (Seco-Alvarez 2011:79-94) where a hoard of clay figurines dating to the Persian Period and associated with Phoenician are dealt with. There may be other hoards, although they are represented by examples sold and bought by private collectors and museums or have, so far, not been published. Both hoards have been associated with possible wrecks, although in both cases, no signs of the wrecks were located. We propose yet another consideration of the hoards which are not associated with shipwrecks, namely a practice of mariners’ ex-voto.

Los efectos de una intervención educativa en materia de derechos humanos con alumnado de Trabajo Social: la valoración de las nociones y el compromiso
Authors: Cubillos-Vega Carla , Ferrán-Aranaz Magdalena
Published: July 2019

Entre los desafíos que en la actualidad tiene por delante la educación en derechos humanos (EDH) se sitúa el desarrollo de elementos para su evaluación y la divulgación de experiencias para su mejora. Este trabajo reporta los resultados de una intervención de EDH con alumnado universitario. Se ha realizado una investigación de diseño cuasiexperimental con grupo control, usando medidas pre y postest, mediante el uso de dos instrumentos validados. Los resultados apuntan a diferencias significativas entre el grupo de control y el de intervención. El aumento significativo de las nociones sobre derechos humanos y compromiso hacia los mismos en el grupo de intervención aporta evidencias para sostener que el conocimiento sobre derechos humanos se relaciona positivamente con el compromiso hacia los mismos.

En consonancia con las aportaciones de Franco Ferrarotti en Histoire et histoires de vie, la methode biographique dans les sciences sociales (París, 1983), donde afirma que a diferencia del sondeo, fotografía instantánea de la realidad social, el material biográfico (cartas) restituye una secuencia temporal, la de una vida, en cuanto que inversamente enraíza la historia del evento en lo cotidiano, en los “grupos humanos, las personas destinadas a permanecer desconocidas, pero que constituyen en su conjunto la sustancia viva, la carne sociológica real del proceso histórico” (p.33). El presente libro está entre lo histórico y lo sociológico y diría que también enlaza lo cotidiano a lo histórico. Y en continuidad discontinua con algunas obras ya clásicas que le han precedido.

E-commerce and digital technologies are bringing opportunities to help SMEs improve their competitiveness, narrow the gap with big enterprises thanks to their fairness and flexibility of the digital business environment. According to UNIDO (2017), India is one of the countries successfully applying e-commerce to SMEs. Contributing to this success is the important role of the Indian government. Therefore, this paper focuses on researching the application of e-commerce to SMEs in terms of the role of government in promoting and creating ecosystem for SMEs and e-commerce development.
DataGauge: A Practical Process for Systematically Designing and Implementing
Quality Assessments of Repurposed Clinical Data
Authors: Diaz-Garelli Jose-Franck , Bernstam Elmer V. , Lee MinJae , Hwang Kevin O. , Rahbar Mohammad H. , Johnson Todd R.
Published: July 2019

The well-known hazards of repurposing data make Data Quality (DQ) assessment a
vital step towards ensuring valid results regardless of analytical methods. However,
there is no systematic process to implement DQ assessments for secondary uses of
clinical data. This paper presents DataGauge, a systematic process for designing and
implementing DQ assessments to evaluate repurposed data for a specific secondary use.
DataGauge is composed of five steps: (1) Define information needs, (2) Develop a formal
Data Needs Model (DNM), (3) Use the DNM and DQ theory to develop goal-specific DQ
assessment requirements, (4) Extract DNM-specified data, and (5) Evaluate according to
DQ requirements. DataGauge’s main contribution is integrating general DQ theory and DQ
assessment methods into a systematic process. This process supports the integration and
practical implementation of existing Electronic Health Record-specific DQ assessment
guidelines. DataGauge also provides an initial theory-based guidance framework that ties
the DNM to DQ testing methods for each DQ dimension to aid the design of DQ assessments.
This framework can be augmented with existing DQ guidelines to enable systematic
assessment. DataGauge sets the stage for future systematic DQ assessment research by
defining an assessment process, capable of adapting to a broad range of clinical
datasets and secondary uses. Defining DataGauge sets the stage for new research
directions such as DQ theory integration, DQ requirements portability research, DQ
assessment tool development and DQ assessment tool usability.

Planificación sostenible de ciudades en El Salvador en adaptación al cambio climático y al ordenamiento territorial sistémico
Authors: Escobar Salmerón Jaime Eduardo
Published: July 2019

El artículo incursiona en la visión de la planificación de ciudades en El Salvador para el siglo XXI desde un enfoque sostenible, el cual debe verse no solamente en la proyección tradicional de construcción de las urbes en relación a principios y criterios ordenadores físico espaciales, sino desde un enfoque más integrador que involucre la respuesta a los desafíos más recientes que enfrentan nuestras poblaciones, tales como: el cambio climático y el ordenamiento territorial. Ambas condiciones suponen la resolución a problemas en dimensiones tales como: la economía, la inclusión social, el medio ambiente y la participación ciudadana; aspectos que aglutinan futuras maneras de resolver problemas de marginación espacial y exclusión de asentamientos humanos precarios, los cuales, a su vez nos obliga a reinventar y revitalizar la planificación urbana para un futuro sostenible e integral mediante la verdadera apropiación de éstas. Además, el artículo supone un análisis para un cambio de paradigma en lo referente a la orientación que deben tener las políticas en materia de proyección y construcción de ciudades que ante una perspectiva sistémica conformen la interrelación entre todos los sistemas de vida en el planeta unidos a aquellos componentes externos tales como: el clima, la geología y su interrelación con el cosmos. Finalmente, concluye en la necesidad de crear una iniciativa de concientización en las prácticas de diseño de ciudades innovadoras para incorporarlas a acciones trascendentales que se enfoquen a la resolución de los desafíos ambientales que demarcan hoy las condiciones del cambio climático global y de la no dependencia hacia los combustibles fósiles, reconvirtiéndolas a la incorporación de sistemas pasivos de energía o de tipo renovables; o el planificar ciudades sostenibles compactas (no dispersas) con servicios de calidad dirigidos al desarrollo socio espacial inclusivo y habitable desde el punto de vista ambiental y del crecimiento económico productivo mediante viviendas dignas y el derecho a la seguridad.

Published: July 2019

Studies about phenotypic diversity are common in germplasm banks. The inference about this variability must be realized through several methods. The multidimensional scaling is a multivariate technique that has not yet been well explored in plant breeding programs. The objective of this study was to evaluate the phenotypic dispersion of landrace lima bean varieties using the non-metric multidimensional scaling technique (nMDS) based on seed morphology. Seeds of 25 lima bean accessions were characterized based on the morphological descriptors proposed by the International Plant Genetic Resources Institute. Distance matrices between the accessions were estimated based on the qualitative and quantitative variables, in addition to simultaneous analysis of the qualitative and quantitative data, using the Mahalanobis and Gower distances. The distances were represented by non-metric multidimensional scaling. The adjustment level of the nMDS mapping was calculated using Kruskal’s Stress. The scaling based on the quantitative and mixed data was efficient to represent the distances of the lima bean accessions in the bidimensional plane presenting Stress less than 20%. Divergent accessions, such as 11, 13, 17 and 25 were identified. The inclusion of qualitative characters provided the best discrimination of the accessions, confirming the importance of the simultaneous character analysis. The nMDS must be used as a complementary technique to those commonly employed in studies of phenotypic diversity in lima beans.

Published: July 2019

Production and use of high quality seeds are essential for the soybean crop. Thus, the quality control system in seeds industry must be reliable, precise, and fast. Tetrazolium test evaluates not only seeds viability but also their vigor, as well as provides information concerning agents that cause their quality reduction. Although this test does not use expensive devices and reagents, it requires a well-trained analyst. Its precision depends on knowledge of all techniques and required procedures. Besides, also necessary is the observer’s subjectivity. So, this trial aimed at developing a computational tool that could minimize the implicit subjectivity in carrying out this test. It also contributes to generate a greater credibility of information and to guarantee precise answers. Algorithms of supervised classification were applied based on extraction of digital images characterization of tetrazolium test. This procedure aimed at producing pixel-based segmentation of those images, to produce a digital segmented image of tetrazolium test according to damage classes. This tool allows, based on image of tetrazolium test, to identify damage on soybean embryos, as well as its site and extension on tissues, so that the interpretation is less subjective. The applied method allowed identifying damage on images of tetrazolium tests in a straightforward way, as well as extracting safer information about those damages and carrying out management control of tetrazolium test according to a seed data file.

The fall armyworm, Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae), a native to the Americas and recently reported in Africa, Germany, the Netherlands and India, is a significant pest of many crop species. Although a widespread and important pest, information on its biology and development are incomplete and require detailed study. In this study, the biotic potential and reproductive parameters of S. frugiperda were evaluated under controlled conditions (25±1 °C, 70±10% RH and 14 hour photophase). The longevity, pre-, post- and oviposition periods, fecundity, and fertility of 30 pairs were evaluated. The longevity of females (10.87 days) was not significantly different from that of males (10.90 days). The mean durations of the pre-, post- and oviposition periods were 2.63, 0.53 and 7.70 days, respectively. The mean fecundity was 2,370.66 eggs per female and mean fertility was 2,309.03 larvae per female. On average, a female copulated 1.6 times. The biotic potential of S. frugiperda was estimated at 2.086 × 1029 individuals/female/year. The net reproductive rate (Ro) was 1,079.73 times per generation and the mean generation time (T) was 32.00 days. The intrinsic rate of increase (rm) was 0.22, with a finite rate of increase (λ) of 1.24 per day. This study evaluates and describes the biological parameters of S. frugiperda with special emphasis on its biotic potential and reproductive parameters. This information will improve the development of integrated pest management (IPM) and insect resistance management (IRM) for this species.

Pineapple (Ananas comosus vr. Comosus) plants require balanced nutrition to meet fruit’s market quality standards for consumption. The objective of this research was to evaluate the effects of organic and mineral fertilization on the development of the ‘Pérola’ pineapple infructescence produced in Paraíba State, Brazil. The plants were conducted under organic fertilization composed by a mixing of cattle manure and poultry litter n at 0, 50, 75 and 100% of the nitrogen doses recommended (NDR) for pineapple cultivation and mineral fertilization. The evaluation for fresh fruit length, diameter, mass, and crown length was initiated at the 43rd day after the floral induction (DAFI). The use organic fertilizer at 75 and 100% of the NDR provided a higher growth rate of fruits. In general, the length and diameter of the infructescences evolved rapidly until the 73rd DAFI, characterizing the first development phase. At the second phase, it was observed an intense growth rate to about the 103rd DAFI be reached, which was followed by a slower growth rate until around the 118th DAFI. In the third and last phase, from the 118th DAFI the physiological maturity of the fruit was reached and was characterized by the pineapple commercial maturation up to 133rd DAFI, with a quarter of the fruit yellow. Under the experimental conditions, the mixed fertilization in the level of 75% NDR, promoted a greater length and fresh mass than the conventional mineral fertilization for ‘Pérola’ pineapple and can be an alternative for this crop’ family farming production.

A fast and non-destructive method is reported to nitrogen, phosphorus and potassium quantification in sorghum, oat, and maize residues. The reflectance spectra of 261 litter plant samples using near-infrared spectroscopy were obtained with integrating sphere and sampling rotator. Second derivative spectra and Partial Least Squares were used to develop calibration and validation models. The cross-validation (leave-one-out) technique was used to evaluate the performance of the calibration and validation models, based on analytical parameters, root-mean-square error of estimation, determination coefficient, number of latent variables, residual prediction deviation, root-mean-square error of cross-validation. It was concluded that near-infrared spectroscopy and chemometric tools are a fast and non-destructive alternative to determine nitrogen and phosphorus content in sorghum, oat, and maize residues using calibration and validation models developed according to values obtained from traditional chemical methods. For potassium content, the results indicate the low quality (imprecision) of the calibration and validation models.

Oszustwa w zakresie podatku od towarów i usług (VAT)1 stanowią najistotniejsze zagrożenie dla finansów publicznych, zaś wyłudzenia zwrotów tego podatku to najbardziej „zyskowna” działalność przestępcza, a do niedawna także łatwa w realizacji, obarczona niewielkim ryzykiem wykrycia i zagrożona nieproporcjonalnie niskimi karami. Co ważne, mechanizm VAT przenosi negatywne konsekwencje, w tym groźbę odpowiedzialności karnej lub karnoskarbowej, na kolejne etapy obrotu – może je ponieść każdy podatnik (osoba dokonująca jego rozliczeń podatkowych lub je nadzorująca), nawet jeżeli sam pozostaje uczciwy, ale utrzymuje relacje handlowe z nieuczciwymi kontrahentami.

As áreas úmidas compreendem vários ecossistemas, dentre eles, os banhados, que são locais estratégicos para conservação devido à sua alta diversidade biológica e produtividade resultante das relações estabelecidas entre a água, solo, vegetação e fauna. A Área de Proteção Ambiental (APA) Fazenda Guajuviras está localizada no município de Canoas (RS) e compreende cerca de 560ha. O objetivo desse estudo foi analisar os níveis de contaminação por bactérias heterotróficas e do grupo coliforme, traçar o perfil bioquímico e identificar alguns isolados bacterianos presentes em dois banhados da APA Guajuviras. Para tanto, as coletas foram realizadas em março de 2015, sendo que cada banhado foi dividido em quatro quadrantes, de onde foram coletadas amostras de 250mL de água. O banhado 2 foi o que apresentou os maiores níveis tanto para coliformes totais como para termotolerantes. Na quantificação das bactérias heterotróficas, os maiores níveis encontrados foram no quadrante norte do banhado 1 e 2. Foram isoladas oito linhagens bacterianas destes banhados. Das linhagens bacterianas obtidas destes banhados, foi possível a identificação, a partir do sequenciamento do gene 16S rRNA, de oito isolados de dois gêneros: Pseudomonas sp. e Serratia sp., e de mais três espécies: Bacillus subtilis, Lactococcus garvieae e Pseudomonas fluorescens.

Skin vasculature and hair follicle cross-talking associated with stem cell activation and tissue homeostasis
Authors: Li Kefei Nina , Jain Prachi , He Catherine Hua , Eun Flora Chae , Kang Sangjo , Tumbar Tudorita
Published: July 2019

Skin vasculature cross-talking with hair follicle stem cells (HFSCs) is poorly understood. Skin vasculature undergoes dramatic remodeling during adult mouse hair cycle. Specifically, a horizontal plexus under the secondary hair germ (HPuHG) transiently neighbors the HFSC activation zone during the quiescence phase (telogen). Increased density of HPuHG can be induced by reciprocal mutations in the epithelium (Runx1) and endothelium (Alk1) in adult mice, and is accompanied by prolonged HFSC quiescence and by delayed entry and progression into the hair growth phase (anagen). Suggestively, skin vasculature produces BMP4, a well-established HFSC quiescence-inducing factor, thus contributing to a proliferation-inhibitory environment near the HFSC. Conversely, the HFSC activator Runx1 regulates secreted proteins with previously demonstrated roles in vasculature remodeling. We suggest a working model in which coordinated remodeling and molecular cross-talking of the adult epithelial and endothelial skin compartments modulate timing of HFSC activation from quiescence for proper tissue homeostasis of adult skin.

Background

Human Metapneumovirus (hMPV) is a negative single-stranded RNA virus. Infection by hMPV mainly affects the pediatric population and can cause upper or lower respiratory tract pathologies which can develop life threating complications. This study was carried out between 2009 and 2010 in a high complexity national hospital in Lima, Peru. The time frame corresponds to the pandemic of influenza A H1N1.

Methods

A prospective study was performed between September 2009 and September 2010. Patients with a clinical diagnosis suggestive of an acute respiratory infection were included. RT-PCR was utilized to attain the amplification and identification of the hMPV.

Results

A total of 539 samples were analyzed from patients with a clinical context suggestive of an acute respiratory tract infection. Of these samples 73, (13.54%) were positive for hMPV. Out of the positive cases, 63% were under one year old, and increased to nearly 80% when considering children younger than two years old. Cough was the most frequent symptom presented by our population with a number of 62 cases (84.93%). Viral seasonality was also established, noting its predominance during the months of summer in the southern hemisphere. The infection by hMPV has an important prevalence in Peru. It mainly affects children under one year old and should be considered an important differential diagnosis in a patient with an acute respiratory infection.

A new non-monofenestratan pterosaur with multicusped dentition,Seazzadactylus venieri, is described from the Upper Triassic (middle-upper Norian) of the Carnian Prealps (northeastern Italy). The holotype ofS. venieripreserves a complete mandibular and maxillary dentition, along with a nearly complete premaxillary one, showing unique features. Furthermore, the arrangement of the premaxillary teeth and the shape of jugal, pterygoid, ectopterygoid, scapula and pteroid are unique within non-monofenestratan pterosaurs.S. venieriis similar and closely related toCarniadactylus rosenfeldiandAustriadraco dallavecchiai, which are also from the Alpine middle-upper Norian of Italy and Austria, respectively. In a parsimony-based phylogenetic analysis,S. venieriis found to nest within a clade of Triassic pterosaurs composed ofArcticodactylus cromptonellus,Austriadraco dallavecchiai, Carniadactylus rosenfeldiand a trichotomy ofRaeticodactylus filisurensis,Caviramus schesaplanensisand MCSNB 8950. This unnamed clade is basal within the Pterosauria, but is not the basalmost clade.Eudimorphodon ranziilies outside this clade and is more derived, making the Eudimorphodontidae paraphyletic.S. venieriincreases the diversity of Triassic pterosaurs and brings the number of pterosaur genera and species in the Dolomia di Forni Formation to four.

The purpose of this study was to assess the effects of powder from Nigella sativa seeds on anthropometrical parameters and appetite in normal weight, overweight and obese subjects. This prospective study was conducted in 85 subjects. 34 adult healthy and normal weight subjects and 51 overweight or obese subjects. Each group was divided into four groups. The first always represented the control group. The subjects were administered at 1 g, 2g and 3 g of Nigella sativa seeds powder orally respectively. Anthropometric indices were evaluated at baseline and at the end of the trial. After 20 min of treatments, the subjective appetite of study participants using a visual analogue scale. The results show that oral administration of powder of Nigella sativa seeds significantly increased scores of appetite and mean BMI value in normal weight subjects and significantly decreased these parameters in overweight and obese subjects. These results may explain the rational uses of this seeds as an appetizer and as an anti-obesity agent in the traditional medicine.

Women are a vital part of the Indian economy and employment to build their empowerment by the provision of loans and financial services is an important aspect of any economy. Rural women of India have been benefited by the Self Help Groups (SHG). The SHG can approach any bank for availing loan facility to undertake any suitable earning activity. The loan is repaid out of the profits earned. A study was carried out for the year 2016-2017 for Amravati division, 50 SHGs, which were engaged in selected agriculture, poultry-based activity. The objectives for the study were to analyze the technical efficient self-help groups and identify the possible determinant of technical efficiency of self-help groups; Primary data was collected with the help of personal interview of self-help groups. Those Self-help groups were selected for the study which has activity in existence of at least 10 years, In poultry SHGs the elasticity of a cost per borrower and subsidy variables were a positively significant contribution in the gross loan. Negative Marginal value productivity of assets, Loan per member and net returns are determined to know the contribution in the gross loan Among selected SHGs, the variations in technical efficiency was 0.7632-0.9966. The study concludes that it is necessary to increase the assets and borrow per member for SHGs income generating activities which will be the make the  SHGs members to increase the net income to refund, therefore assets, borrow per member and net returns are the possible determinant of the gross loan portfolio.  The amount needs to be fixed according to the income generating activities and borrow per member increases contribute more to their family income.
Variations in Total Species Richness and the Unevenness of Species Abundance Distribution between Two Distant Conus Communities (Neogastropoda): A Case Study in Mannar Gulf (India)
Authors: Béguinot Jean
Published: July 2019

The genus Conus forms a conspicuous and rather homogeneous group within marine Gastropods. This makes it all the more interesting to focus on the sub-communities formed by Conus species and to analyze the potential specificities in the internal organization of species in these communities, in particular species richness, species abundance distribution and the effect of geographical distance between communities on differences in their respective species composition. Accordingly, two Conus communities along the coast in Mannar Gulf (India), separated by 80 km, are considered. Reliable analysis requires, first, to treat exhaustive data from complete samplings or, else – as here – to implement an appropriate extrapolation procedure to complete numerically the partial samplings. After numerical completion, substantial differences were highlighted between the two communities, not only in terms of true (total) species richness but, even more, as regards the profile and the average unevenness of the distributions of species abundance. Also, significant dissimilarity in species composition was found between the two communities, that may be tentatively attributed to either deterministic distance decay in similarity of species composition or, alternatively, to the persistence in the stochastic process of species recruitment from the regional stock of Conus planktonic larvae. This preliminary study yet requests to be complemented by other similar case studies, before drawing any safer interpretative conclusions.
Unraveling the Metaphysical, Epistemological, and Ethical Elements of Oromo Proverbs

Long ago the external world (most prominent among which is the west) had excommunicated African mind from the realm/ treasure of reasoned knowledge. According to Hegel, Hume, Kant, and others, for any thought (about human life, about knowledge and truth, good and bad, right and wrong, mind and matter; about human nature and the universe we inhabit) to count as reasoned knowledge it must be subject to writing. African philosophers like Hountondji, Appiah, Bondurin, etc. have also expounded that individualist element, the main or only yardstick of reasoned knowledge, as they have put it, is missing in the traditional genre of thought. Apiece of these characterizations are unfair as they have indisputably tried to discredit the thoughtful knowledge built on oral tradition.

The central point in this article, therefore, is unraveling the practical reasoned knowledge exhibited in the traditional genre of thought. The aspiration is partly alluded to the task of being informative about the place of Oromo society and, by extension, traditional African thought in the realm of global knowledge.

This is done by closely examining the metaphysical, epistemological, and ethical elements embedded in some proverbs of the Oromo.

A novel thermoalkalophilic α-amylase producing bacterial strain Bacillus sonorensis GV2 |KJ775811.1| was isolated from mushroom compost. The purification of α-amylase was performed through different chromatography techniques. After purification with SDS-PAGE and Sephadex G-75 gel filtration, the molecular weight of monomeric α-amylase was found to be 45 kDa. The enzyme showed an optimal activity over a wide range of temperature and pH of 35-60oC and 7-11, respectively. The effect of divalent ions i.e. Mg2+ and Ca2+ showed a positive increase in enzyme activity. This enzyme is unique in a sense that it also exhibited a considerable raw corn starch hydrolyzing activity at 55oC. The end products when subjected to TLC which were identified as main maltooligosaccharides, proving the endo action of an enzyme. The Vmax and Km values of Bacillus sonorensis GV2 α-amylase were found to be 1347 μmol/mg/min and 3.46  mMol/ml. The MALDI peptide mass fingerprint analysis of the reduced and carboxymethylated amylase digested with chymotrypsin indicated that this partial amino acid sequence was homologous by a score of 6 with UDP transferalyase. All these findings suggests about the potential role of this α-amylase for raw starch degrading applications in the relevant industry.

On‐skin electronics require conductive, porous, and stretchable materials for a stable operation with minimal invasiveness to the human body. However, porous elastic conductors that simultaneously achieve high conductivity, good stretchability, and durability are rare owing to the lack of proper design for good adhesion between porous elastic polymer and conductive metallic networks. Here, a simple fabrication approach for porous nanomesh‐type elastic conductors is shown by designing a layer‐by‐layer structure of nanofibers/nanowires (NFs/NWs) via interfacial hydrogen bonding. The as‐prepared conductors, consisting of Ag NWs and polyurethane (PU) NFs, simultaneously achieve high conductivity (9190 S cm−1), high stretchability (310%), and good durability (82% resistance increase after 1000 cycles of deformation at 70% tensile strain). The direct contact between the Ag NWs enables the high conductivity. The synergistic effect of the layer‐by‐layer structure and good adhesion between the Ag NWs and the PU NFs enables good mechanical properties. Furthermore, without any adhesive gel/tape, the conductors can be utilized as breathable strain sensors for precise joint motion monitoring, and as breathable sensing electrodes for continuous electrophysiological signal recording.

The deposition of protein thin films on (in)organic surfaces is a key approach to incorporate new functionalities into these materials for a broad number of applications. However, most of the current methods used for the controlled assembly of such biomolecules and eventual film formation are limiting since entail either the chemical modification of the proteins, which leads sometimes to impaired materials, or the sequential layer‐by‐layer deposition of charged macromolecules. In this work, a facile bioinspired method for the versatile fabrication of robust catalytic films is developed. The herein shown approach involves the one‐pot synthesis of porous enzyme nanogels decorated with imidazole motifs. These nanogels act as small nanoreactors that are further self‐assembled into continuous catalytic nanocoatings through metal‐imidazole coordination. An extensive structural, chemical, and functional characterization of the biocatalytic coatings evidences the integrity, stability in organic solvents and high temperatures, and the reusability of the deposits. Moreover, the thickness and metal composition of the nanocoatings can be tuned on demand. Finally, interesting applications for the bioinspired films are demonstrated, i.e., the fabrication of a glucose electrochemical biosensor and the completion of tandem enzymatic reactions, which suggest a broad applicability potential of this methodology.
