Is Central Pancreatectomy Truly Recommendable? A 9-Year Single-Center Experience
Authors: Lv Ang , Qian Hong-Gang , Qiu Hui , Wu Jian-Hui , Hao Chun-Yi 
Published: December 2017

<b><i>Aims:</i></b> To compare the short- and long-term outcomes in patients with pancreatic benign or borderline neoplasm who underwent central pancreatectomy (CP) and distal pancreatectomy (DP). <b><i>Methods:</i></b> The inclusion criteria were as follows: (1) single benign or low-grade malignant tumor; (2) tumor conﬁned to the pancreatic neck or proximal body; and (3) tumor amenable to either CP or DP. Short and long-term outcomes, including complications, pancreatic exocrine and endocrine function, and quality of life (QoL) were analyzed retrospectively. <b><i>Results:</i></b> Sixteen patients who underwent CP and 26 patients who underwent DP were included. The median follow-up period was 53 months (range 21–117 months). Patients undergoing CP were significantly more likely to experience complications (68.7 vs. 23%, <i>p</i> = 0.003) especially grade B/C postoperative pancreatic fistula (62.5 vs. 23%, <i>p </i>= 0.011) than those undergoing DP. During the long-term follow-up, 2 patients in the DP group developed new-onset diabetes mellitus, but no patient in CP group developed this condition (8 vs. 0%, <i>p</i> = 0.382). Evidence of exocrine insufficiency, including severe diarrhea or steatorrhea, was not observed in either group. Both groups were equally satisfied with the overall health status and overall QoL. <b><i>Conclusion:</i></b> CP is associated with excellent pancreatic function but a significantly increased postoperative morbidity and risk compared to DP. Therefore, the indication of CP should be chosen strictly.
From Gurudev to Doctor-Sahib
Authors: Heifetz Daniel Philip 
Published: December 2017

AbstractThe All World Gayatri Pariwar is a modern Hindu movement working to revive ancient Vedic-style rituals. The movement was founded by a charismatic figure named Shriram Sharma, but is now headed by his successor, a medical doctor named Pranav Pandya. I argue that the continued vitality of the movement in the absence of its charismatic founder has to do with the ways in which Pandya’s scientific authority as a medical doctor replaces Sharma’s charismatic authority. By attending to the affective dimensions of these two forms of authority, their differences become less stark and it becomes clear how scientific authority, despite its seeming disenchantment, might retain some of the emotional power of charismatic authority.
Image quality assessment of silent T
2 PROPELLER sequence for brain imaging in infants
Authors: Kim Hyun Gi , Choi Jin Wook , Yoon Soo Han , Lee Sieun 
Published: December 2017

Objective:
Infants are vulnerable to high acoustic noise. Acoustic noise generated by MR scanning can be reduced by a silent sequence. The purpose of this study is to compare the image quality of the conventional and silent T2 PROPELLER sequences for brain imaging in infants.

Methods:
A total of 36 scans were acquired from 24 infants using a 3 T MR scanner. Each patient underwent both conventional and silent T2 PROPELLER sequences. Acoustic noise level was measured. Quantitative and qualitative assessments were performed with the images taken with each sequence.

Results:
The sound pressure level of the conventional T2 PROPELLER imaging sequence was 92.1 dB and that of the silent T2 PROPELLER imaging sequence was 73.3 dB (reduction of 20%). On quantitative assessment, the two sequences (conventional vs silent T2 PROPELLER) did not show significant difference in relative contrast (0.069 vs 0.068, p value = 0.536) and signal-to-noise ratio (75.4 vs 114.8, p value = 0.098). Qualitative assessment of overall image quality (p value = 0.572), grey-white differentiation (p value = 0.986), shunt-related artefact (p value &gt; 0.999), motion artefact (p value = 0.801) and myelination degree in different brain regions (p values ≥ 0.092) did not show significant difference between the two sequences.

Conclusion:
The silent T2 PROPELLER sequence reduces acoustic noise and generated comparable image quality to that of the conventional sequence.

Advances in knowledge:
This is the first report to compare silent T2 PROPELLER images with that of conventional T2 PROPELLER images in children.
Transcriptional responses of Anopheles gambiae s.s mosquito larvae to chronic exposure of cadmium heavy metal
Authors: Muturi Catherine N. , Rono Martin K. , Masiga Daniel K. , Wachira Francis N. , Ochieng Richard , Mireji Paul O. 
Published: December 2017

Background: Anopheles gambiae larvae traditionally thrive in non-polluted environments. We previously documented the presence of the larvae in heavy metal polluted urban aquatic environments and the associated biological cost. The goal of this study was to unravel the molecular dynamics involved in the adaptation of the mosquitoes to the heavy metals. Methods: Total RNA was extracted from third instar larvae of both cadmium treated populations and untreated control populations. The RNA concentrations were normalized and complementary DNAs were prepared. Then annealing control primer (ACP) technology was applied to establish transcriptional responses in An. gambiae larvae following several generational (n=90) chronic exposures to cadmium. Differentially expressed genes were determined by their differential banding patterns on an agarose gel. Gel extraction and purification was then carried out on the DEGs and these were later cloned and sequenced to establish the specific transcripts. Results: We identified 14 differentially expressed transcripts in response to the cadmium exposure in the larvae. Most (11) of the transcripts were up-regulated in response to the cadmium exposure and were putatively functionally associated with metabolism, transport and protein synthesis processes. The transcripts included ATP-binding cassette transporter, eupolytin, ribosomal RNA, translation initiation factor, THO complex, lysosomal alpha-mannosidase, sodium-independent sulfate anion transporter and myotubularin related protein 2. The down-regulated transcripts were functionally associated with signal transduction and proteolytic activity and included Protein G12, adenylate cyclase and endoplasmic reticulum metallopeptidase. Conclusions: Our findings shed light on pathways functionally associated with the adaptation to heavy metals that can be targeted in integrated vector control programs, and potential An. gambiae larvae biomarkers for assessment of environmental stress or contamination.
Cannulated screw versus Kirschner-wire fixation for Milch II lateral condyle fractures in a paediatric sawbone model: A biomechanical comparison
Authors: Franks D. , Shatrov J. , Symes M. , Little D. G. , Cheng T. L. 
Published: December 2017

Purpose Lateral condyle fractures of the humerus are common in the paediatric population, accounting for up to 20% of elbow fractures. Traditional management involves internal fixation with Kirschner (K)-wires, however, this has been associated with complications and insufficiently rigid fixation. Recently, cannulated screws have been proposed as a more stable method of fixation. While cannulated screws have been thought to allow earlier range of movement and shorten time to union, data regarding the biomechanical performance and optimal screw placement is scarce. We hypothesize that cannulated screw fixation is superior to K-wire fixation and screw placement can enhance the stability of the construct. Methods Paediatric humerus sawbones with Milch II fractures were fixed with one of three methods. Fractures were reduced with either a single cannulated screw either through the centre of the capitellum (oblique), or placed up the lateral column across the growth plate (lateral), or fixed with two K-wires. Fixed sawbone fractures were then mechanically tested in two directions simulating in vivo forces. Results The lateral screw construct had a higher maximum force to failure, higher stiffness and absorbed higher energy as compared with the K-wire fixation and oblique screw under an anterior force. When loaded from the posterior direction, only the lateral column screw was better than K-wire fixation. Conclusions Screw fixation is a biomechanically effective alternative to K-wire fixation, especially when placed up the lateral column of the distal humerus. Further clinical studies are required before transcapitellar screw fixation can be adopted.
‘Let Prudence Plain-Dress be your companion’: Dress of female preachers during the Second Great Awakening (1790–1865)
Authors: Strifler Jennise , Mamp Michael 
Published: December 2017

Abstract
The Second Great Awakening (1790–1865) created large numbers of new Christian congregants. In order for churches to effectively minister their burgeoning populations, they enlisted the help of women to serve as itinerant preachers. This research analysed the autobiographies of female preachers, period newspaper articles and imagery to better understand the relationship between the sartorial choices and public personas of female preachers. Most did not align themselves with feminist ideologies of the time but rather claimed the will of God as justification. However, these women were highly criticized and therefore sought a balance between their gender and their faith. This was achieved in part through the adoption of a plain style of dress that stood in stark contrast to superfluous fashions of the time. The style of plain dress was modelled after the attire of the Quakers with neutral colours, no embellishments and simple fabrications. Women were told by male preachers, such as John Wesley, that they should dress plainly. Many congregants, as well as female preachers, told stories of extreme conversions where they immediately eschewed their fashionable clothing.
Miki Vargas: Queer-fashion photographer and The Handsome Revolution
Authors: Reddy-Best Kelly L. 
Published: December 2017

Abstract
This study documents and analyses the life and work of Miki Vargas (1973–present), a photographer who captured and promoted images, for both commercial and personal projects, of masculine women and transmen and circulated these photographs in the media where this aesthetic is largely if not almost entirely absent. Vargas worked at the forefront of the burgeoning queer-fashion movement in the twenty-first century as the cornerstone photographer for Saint Harridan, a lesbian, gay, bisexual, transgender, queer and/or questioning (LGBTQ)-focused brand selling men’s fashion to masculine-of-centre women and transmen. Alongside her commercial work, Vargas created a personal series, The Handsome Revolution, where she captured the fashions and aesthetics of masculine-presenting women or transmen, which have quite a similar aesthetic to her work for Saint Harridan. In this article, I also analyse the alternative styles/photographs in The Handsome Revolution and corresponding statements of what masculinity meant to each participant, which Vargas documented for 98 LGBTQ women and transmen. I highlight how Vargas’ photography work created a space for gender non-conforming individuals to feel empowered by their masculine appearance, aesthetic and continual subject formation. This research examines the ongoing possibilities of gender expression in relation to fashion.

Objective: the aim of the present study was to evaluate the influence of adding different concentrations of chitosan to an experimental two-step etch-and-rinse adhesive system on the bond strength and failure mode to dentin. Material and Methods: thirty-two flat dentin surfaces were obtained from extracted human third molars and divided into four groups (n=8) for application of the adhesive systems: AD - conventional two-step adhesive system (Adper Single Bond 2); EXP – experimental two-step etch-and-rinse adhesive system; Chi0.2% - EXP with addition of 0.2% Chitosan; Chi0.5% - EXP with addition of 0.5% Chitosan. Resin composite build-ups were made and the composite/dentin specimens were sectioned to obtain rectangular beams with a bond area of approximately 1mm2. After 24 hours, the sticks were submitted to microtensile bond strength tests in a universal test machine. The fracture pattern was evaluated under a stereoscopic loupe at 40X magnification. Results: one-way analysis of variance showed that the type of adhesive system had no significant effect on the bond strength values (p = 0.142), showing the mean bond strength values (standard deviation), in MPa, for the groups as follows: AD=20.1 (5.4); EXP=16.6 (2.3); Chi0.2%=16.1 (2.8); Chi0.5%=16.9 (2.3). In all the groups there was predominance of cohesive fractures in dentin, representing 68 to 82% of the failure modes. Conclusion: the addition of 0.2 or 0.5% of chitosan had no influence on the bond strength and failure mode of an experimental two-step etch-and-rinse adhesive system to dentin.KeywordsChitosan; Dental Adhesives; Failure Mode; Microtensile Bond Strength.
Eje 1. Documentales, actores, personajes y circuitos de circulación: Relaciones cinematográficas transnacionales entre México y España: el caso de las producciones Calderón
Authors: Flores Silvana 
Published: December 2017

En este artículo se enumerarán y analizarán los nexos transnacionales que se han efectuado durante el período clásico–industrial del cine mexicano con España, teniendo en cuenta diferentes mecanismos de intercambio que incluyen, entre varios aspectos, la migración de actores y directores desde Europa hacia América, las transacciones de coproducción, la conformación de parejas transnacionales en la estructura dramática de los filmes y la inclusión de temáticas y elementos culturales vinculados al hispanismo. Considerando que este fenómeno abarca largo tiempo, además de géneros y corrientes estéticas, el estudio será circunscripto a las producciones realizadas por los hermanos José Luis, Pedro y Guillermo Calderón, empresarios cinematográficos mexicanos que desplegaron una amplia productividad en dichas conexiones y perduraron a lo largo de las décadas. Se apuntará en consecuencia a comprobar que la integración continental e intercontinental ha existido en el área del cine aun con anterioridad a la modernización de las cinematografías latinoamericanas en los años sesenta.

Published: December 2017

<p class="p1">Vibrational spectroscopic techniques have advantages over conventional microbiological approaches towards identification &amp; detection of pathogens. Since unique spectral fingerprint is obtained, one can identify very closely related bacteria using such methods. In this study Raman microspectroscopy in combination with chemometric method has been used to classify four strains of <em>E</em>. <em>coli </em>(two pathogenic &amp; two non-pathogenic). Different multivariate approaches such as hierarchical cluster analysis, principal component analysis &amp; linear discriminant analysis were explored to obtain efficient classification of the Raman signals obtained from the four strains of <em>E.coli</em>. It was observed that multivariate analysis was able to classify the bacteria at strain level. Linear discrimination analysis using PC scores (PC-LDA) was found to give very good result with as high as 100% accuracy. This hybrid technique (Raman spectroscopy &amp; multivariate analysis) has tremendous potential to be developed as a tool for bacterial identification.<span class="Apple-converted-space"> </span></p>

Published: December 2017

<p class="p1">We report the ‘standoff detection’ of explosives at 1 m in laboratory conditions, for the first time in India, using Laser Induced Breakdown Spectroscopy combined with multivariate analysis. The spectra of a set of five secondary explosives were recorded at a distance of 1 m from the focusing as well as collection optics. The plasma characteristics viz., plasma temperature and electron density were estimated from Boltzmann statistics and Stark broadening respectively. Plasma temperature was estimated to be of the order of (10.9 ± 2.1) .103 K and electron density of (3.9 ± 0.5) .1016 cm-3. Using a ratiometric approach, C/H and H/O ratios showed a good correlation with the actual stoichiometric ratios and a partial identification success could be achieved. Finally employing principle component analysis, an excellent classification could be attained.<span class="Apple-converted-space"> </span></p>

Published: December 2017

AbstractThe objective of the paper was to show various options of using by author an automated stand with computer image analysis for control of plant germination on the example of cauliflower Brassica oleracea L. ‘Pionier” variety. The developed system consisted of a mobile platform equipped with the acquisition and image processing system based on Raspberry PL processor. Germination of cauliflower seeds was the object of observation, which in one case were sown to soil after dressing them with plant extracts (sweet flagAcorus calamusL., great burdock rootsArctium lappaL.). In the other case, undressed seeds were sown in the place of previous application of the above-mentioned extracts. The use of a robot for monitoring plant germination enabled the automated analysis of the investigated material with higher frequency than it has been possible so far. Simultaneously, higher germination was reported when seeds were treated with macerates and extracts from great burdock roots.

Published: December 2017

Abstract
The investigations deal with mass transfer in simulated biomedical systems. The modification of classical diffusion chamber, sequential unit (SU) system, imitated different biomedical setups, boundary conditions. The experiments simulated: diffusion chamber (also with two barriers), transport through the membrane to the blood stream, transport from the stent eluting drug simultaneously to the vessel cells and to the blood stream. The concentrations of substances and the relative mass increases/decreases for SU systems indicate that the order of the curves follows the order of mass transfer resistances. The strong dependence of mass transfer rates versus type of diffusing substance was confirmed. The calculated drug fluxes, diffusion coefficients, permeation coefficients are convergent with literature. Permeation coefficients for complex sequential systems can be estimated as parallel connexion of constituent coefficients. Experiments approved functionality of the SU for investigations in a simulated biomedical system. Obtained data were used for numerical verification.
Changes of the peripheral blood mononuclear cells membrane fluidity from type 1 Gaucher disease patients: an electron paramagnetic resonance study

Published: December 2017

Abstract
Gaucher disease (GD) is a lysosomal storage disorder, caused by an impaired function of β-glucocerebrosidase, which results in accumulation of glucocerebroside in cells, and altered membrane ordering. Using electron paramagnetic resonance spin labeling, a statistically significant difference in the order parameter between the peripheral blood mononuclear cell membranes of GD patients and healthy controls was observed. Moreover, the results show that the introduction of the enzyme replacement therapy leads to the restoration of the physiological membrane fluidity. Accordingly, this simple method could serve as a preliminary test for GD diagnosis and therapy efficiency.
The Voice of Conscience, Kierkegaard’s Theory of Indirect Communication, and Buber’s Philosophy of Dialogue
Authors: Welz Claudia 
Published: December 2017

AbstractThis paper investigates the concept and the experience of conscience as an interface of aesthetic, ethical, and religious aspects of Kierkegaard’s existential approach, while criticizing his reductionist definition of ‘aesthetics’ and the opposition he draws between ethics and aesthetics. A comparison of Kierkegaard’s theory of indirect ‘existence’-communication with Martin Buber’s philosophy of dialogue shows that Kierkegaard overlooks three crucial moments of truly liberating, conscientious communication, including the dialogical dynamics of becoming-oneself vis-à-vis the Other.
