Cirugía Colo-rectal Laparoscópica en 3D. ¿Recomendamos su implantación?
Authors: Loreto Brand Mariana Elisa 
Published: September 2018

La cirugía laparoscópica en 3D se presenta como una alternativa a los inconvenientes de la laparoscopia convencional. A pesar de los resultados discordantes de los primeros estudios realizados en 1998, los avances tecnológicos, la cada vez más frecuente experiencia de los cirujanos con las intervenciones laparoscópicas y su indicación habitual, han permitido que nuevas investigaciones en dicho campo muestren unos resultados más alentadores.
El uso de tecnología tridimensional en la cirugía laparoscópica ha evolucionado desde sus inicios, pudiendo identificar situaciones propias por su uso como el ghosting-crosstalk y conceptos nuevos para el equipo quirúrgico que no se habían presentado en la cirugía laparoscópica convencional, como el de estereoagudeza / estereoceguera.
A pesar de los beneficios hipotéticos y comprobados de la cirugía laparoscópica tridimensional (mejor percepción de profundidad, seguridad al realizar movimientos complejos, mayor precisión quirúrgica y menor curva de aprendizaje), los puntos débiles a tener en cuenta son: necesidad de estereopsis normal (normalmente no estudiada en el equipo quirúrgico), beneficio en ciertos pasos de la cirugía (anastomosis y suturas) con menor grado de ventaja en las intervenciones con menos necesidad de estas acciones y pocos ensayos clínicos con un diseño adecuado y un número de casos que brinden suficiente validez estadística.
Por todo esto, es imposible recomendar al 100% la cirugía colo-rectal laparoscópica sin mayores estudios a disposición; aunque si se puede hacer mención a la alta posibilidad de que la misma sea poco a poco aceptada, siendo coherente y esperable con los avances tecnológicos y el interés de los mismos cirujanos sobre esta técnica.

Metode yang digunakan dalam penelitian ini adalah metode penelitian deskriptif, yang mana penulis hanya menggambarkan masalah sebagaimana adanya atau sesuai dengan kenyataan yang terjadi pada objek penelitian. Dalam teknik pengumpulan data penulis melakukan observasi yaitu pengamatan secara langsung di lapangan, serta dokumentasi berupa foto-foto dan wawancara secara langsung.
Hasil penelitian ini menunjukkan bahwa PT Jasa Raharja (Persero) Cabang Kalimantan Selatan memiliki sekretaris yang kurang menguasai skill dasar sebagai seorang sekretaris sehingga menyebabkan kinerja sekretaris kurang efektif dan efisien. Hal ini disebabkan karena sekretaris merupakan seorang lulusan Sarjana Komputer sehingga tidak memiliki pengetahuan mendasar mengenai kesekretarisan, dan juga dikarenakan perusahaan tidak pernah memberikan pelatihan khusus tentang kesekretarisan. Untuk mengatasi masalah ini sekretaris harus berinisiatif untuk mengembangkan skill salah satunya dengan cara mempelajari literature yang ada hubungannya dengan skill tersebut, selain itu perusahaan juga harus mengadakan pelatihan untuk sekretaris dengan menerapkan sasaran pelatihan, menyusun kurikulum, menetapkan sarana, memilih peserta, dan menetapkan waktu pelaksanaan. Dengan melakukan strategi tersebut maka skill sekretaris akan berkembang dan kinerja sekretaris akan menjadi lebih baik.
An invitro study on the regulation of oxidative protective genes in human gingival and intestinal epithelial cells after treatment with salmon protein hydrolysate peptides
Authors: Framroze Bomi , Havaldar Freddy , Misal Shashi 
Published: September 2018

Background: Under physiological conditions, molecular oxygen generates reactive oxygen species (ROS) as metabolic by-products. In the absence of an adequate defense mechanism, the accumulation of ROS leads to cell membrane and DNA damage, in addition to tissue degeneration. The up/down regulation of one or more oxidative stress-related genes is one mechanism which confers cytoprotection to tissues exposed to oxidative injury.Methods: We measured up/down regulation of 84 oxidative protective genes in primary human gingival epithelial pooled cells and human intestinal epithelial cells after pretreatment with 25, 50, and 100 μM/ml of salmon protein hydrolysate solution. A human RT2 Profiler PCR array was used to evaluate the relative change in the expression of these common oxidative protective genes. The salmon protein hydrolysate contains a mixture of bioactive peptides, resulting from enzyme hydrolysis of salmon head and backbones.Results: Treatment with salmon protein hydrolysate peptides demonstrated up-regulation for 16 human oxidative protective genes and down-regulation for 9 human oxidative stress-related genes. Three genes (ferritin heavy polypeptide-1 (FTH1), heme oxygenase-1 (HMOX1), and arachidonate 12-lipoxygenase (ALOX12)) showed regulation changes at physiologically applicable levels.Conclusions The improved oxidation protection observed after SPH treatment conferred by HMOX1 / ALOX12 regulation to HGEPp and HIEC-6 cells may find ultimate utility for these bioactive peptides in the modulation of gastrointestinal stress in irritable bowel syndrome and enterocolitis.
The relationship of cervical microbiota diversity with race and disparities in preterm birth
Authors: Wheeler Sarahn , Pryor Katherine , Antczak Brian , Truong Tracy , Murtha Amy , Seed Patrick 
Published: September 2018

OBJECTIVE: Pregnant non-Hispanic blacks (NHB) have increased vaginal microbiome diversity compared to non-Hispanic whites (NHW) which may contribute to increased preterm birth. Cervical microbiome diversity is poorly characterized in pregnancy, therefore our objective was to correlate cervical microbiota diversity with cervico-vaginal inflammation by race and delivery timing. STUDY DESIGN: Pregnant women were recruited in the first and second trimesters. A sterile cervical swab and saline lavage were collected at a single time point. Using 16S rRNA sequencing, Chao1 and Shannon Diversity (SDI) indicies were measured and compared by race and delivery timing (preterm vs. term delivery). Cervico-vaginal inflammatory markers were also compared by race and delivery timing. Spearman correlation coefficients between cervical microbiome diversity and cervico-vaginal inflammatory markers were calculated. RESULTS: Of the 51 subjects, 39 (76%) were NHB and 12 (24%) were NHW. Cervical microbiota SDI was significantly higher in NHB compared to NHW (0.5 vs. 0.1; p = 0.03). However, there were no difference in Chao1 diversity or cervico-vaginal inflammatory markers by race or delivery timing. CONCLUSION: Our findings suggest the cervical microbiota diversity during pregnancy differs by race. Larger cohort studies will further determine if altered cervical diversity is part of the pathogenesis of PTB and explains race disparities.
Manuscript Culture as Ritual Culture in Late Medieval Dunhuang: Buddhist Talisman-Seals and their Manuals
Authors: Copp Paul 
Published: September 2018

Cet essai propose une étude de quatre versions d'un manuel de rites ayant trait à la confection et à l'utilisation de talismans et de sceaux (fuyin) lesquels ont été conservés parmi des manuscrits de Dunhuang, sur les trois parchemins et le codex intitulés respectivement Pelliot Chinois 2153, 2602, 3874, and 3835. L'auteur explore la place de ces ouvrages dans les pratiques rituelles et textuelles qui sembleraient les avoir engendrés. En termes de pratiques rituelles, l'étude décrit le culte à Ruyilun, la
principale divinité tutélaire des sceaux, à la fin du moyen âge chinois et esquisse les grandes lignes du phénomène des sceaux rituels et des pratiques dans lesquels ils figuraient. Pour ce qui concerne les quatre versions, l'étude constate d'importantes divergences textuelles et de présentation, reflet d'une pratique très variable des copistes. Cette diversité se retrouve au niveau des sceaux tels qu'ils sont décrits et dessinés sur la page. Les variantes distinctives d'une version manuscrite à l'autre du texte — phénomène courant en codicologie — sont explorées ici comme l'expression des pratiques rituelles et des répertoires particuliers. L'article suggère enfin que ces manuscrits offrent le témoignage d'une culture religieuse dans laquelle le manuscrit et les pratiques rituelles étaient profondément liées.

Abstract
We report on the design and performance of the Keck Cosmic Web Imager (KCWI), a general purpose optical integral field spectrograph that has been installed at the Nasmyth port of the 10 m Keck II telescope on Maunakea, Hawaii. The novel design provides blue-optimized seeing-limited imaging from 350–560 nm with configurable spectral resolution from 1000–20,000 in a field of view up to 20″ × 33″. Selectable volume phase holographic (VPH) gratings and high-performance dielectric, multilayer silver, and enhanced-aluminum coatings provide end-to-end peak efficiency in excess of 45% while accommodating the future addition of a red channel that will extend wavelength coverage to 1 micron. KCWI takes full advantage of the excellent seeing and dark sky above Maunakea with an available nod-and-shuffle observing mode. The instrument is optimized for observations of faint, diffuse objects such as the intergalactic medium or cosmic web. In this paper, a detailed description of the instrument design is provided with measured performance results from the laboratory test program and 10 nights of on-sky commissioning during the spring of 2017. The KCWI team is lead by Caltech and JPL (project management, design, and implementation) in partnership with the University of California at Santa Cruz (camera optical and mechanical design) and the W. M. Keck Observatory (observatory interfaces).
Une approche philosophique de la vulnérabilité. À l’écoute d’une « toute petite fille »
Authors: Portets Noëlle , Dupeyron Jean-François 
Published: September 2018

Une approche féministe nous amènera à questionner le concept de vulnérabilité dans son lien à celui d’autonomie et d’autosuffisance, en le situant dans son contexte social, économique et politique contemporain. De la lecture de plusieurs auteurs sur cette thématique, nous ferons émerger notre hypothèse : elle sera de considérer que la vie tient d’une tension constante entre puissance d’agir et vulnérabilité, exposition à la blessure et normativité. Afin d’expliciter cette approche, nous suivrons un bout d’histoire : celle d’une « toute petite fille » ( La Pivellina ), de Patti, qui va accueillir cette enfant en situation de vulnérabilité, et de son entourage. Dans cette situation se trouvent mis en pratique un accueil, une éthique du care , à l’écoute d’une enfant, dans un moment donné de son histoire. Puis nous conclurons par les propos du philosophe Jean-François Dupeyron s’attachant à penser les liens entre enfant « tendre » et vulnérabilisation.
La maxime d’Hevenesi : une formule paradoxale de l’agir chrétien
Authors: Valadier Paul 
Published: September 2018

Dans le débat sur l’articulation entre morale et spiritualité, la maxime du jésuite Hevenesi occupe une place privilégiée. Caractéristique de la spiritualité et de la théologie ignatiennes, elle indique une manière de penser le lien entre liberté humaine et liberté divine qui récuse les dualismes courants en ce domaine entre grâce et liberté, entre action de Dieu et volonté humaine. Cette posture théologique permet de fonder un discernement et une décision morale sur « l’admirable échange » qui en christianisme préside à la relation entre Dieu et l’homme. Ce texte est un extrait du commentaire fait par le Père Paul Valadier dans son livre La condition chrétienne. Du monde sans en être , Éd. du Seuil, Paris, 2003.
On the spectral depolarisation and lidar ratio of mineral dust provided in the AERONET version 3 inversion product
Authors: Shin Sung-Kyun , Tesche Matthias , Kim Kwanchul , Kezoudi Maria , Tatarov Boyan , Müller Detlef , Noh Youngmin 
Published: September 2018

Abstract. Knowledge of the particle lidar ratio (Sλ) and the particle linear
depolarisation ratio (δλ) for different aerosol types allows
for aerosol typing and aerosol-type separation in lidar measurements.
Reference values generally originate from dedicated lidar observations but
might also be obtained from the inversion of AErosol RObotic NETwork (AERONET) sun/sky radiometer
measurements. This study investigates the consistency of spectral Sλ
and δλ provided in the recently released AERONET version 3
inversion product for observations of undiluted mineral dust in the vicinity
of the following major deserts: Gobi, Sahara, Arabian, Great Basin, and Great Victoria. Pure dust conditions are identified by an Ångström exponent
<0.4 and a fine-mode fraction <0.1. The values of spectral Sλ are found to vary for the different source
regions but generally show an increase with decreasing wavelength. The
feature correlates to AERONET, retrieving an increase in the imaginary part of
the refractive index with decreasing wavelength. The smallest values of
Sλ=35–45 sr are found for mineral dust from the Great Basin
desert,
while the highest values of 50–70 sr have been inferred from AERONET
observations of Saharan dust. Values of Sλ at 675, 870, and 1020 nm
seem to be in reasonable agreement with available lidar observations, while
those at 440 nm are up to 10 sr higher than the lidar reference. The
spectrum of δλ shows a maximum of 0.26–0.31 at 1020 nm and
decreasing values as wavelength decreases. AERONET-derived δλ
values at 870 and 1020 nm are in line with the lidar reference, while values of
0.19–0.24 at 440 nm are smaller than the independent lidar observations by
a difference of 0.03 to 0.08. This general behaviour is consistent with
earlier studies based on AERONET version 2 products.
Exploring the first aerosol indirect effect over Southeast Asia using a 10-year collocated MODIS, CALIOP, and model dataset

Published: September 2018

Abstract. Satellite observations and model simulations cannot, by themselves, give full insight into the complex relationships between aerosols and clouds. This is especially true over Southeast Asia, an area that is particularly sensitive to changes in precipitation yet poses some of the world's largest observability and predictability challenges. We present a new collocated dataset, the Curtain Cloud-Aerosol Regional A-Train dataset, or CCARA. CCARA includes collocated satellite observations from Aqua's Moderate-resolution Imaging Spectroradiometer (MODIS) and the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) with the Navy Aerosol Analysis and Prediction System (NAAPS). The CCARA dataset is designed with the capability to investigate aerosol–cloud relationships in regions with limited aerosol retrievals due to high cloud amounts by leveraging the NAAPS model reanalysis of aerosol concentration in these regions. This combined aerosol and cloud dataset provides coincident and vertically resolved cloud and aerosol observations for 2006–2016. Using the model reanalysis aerosol fields from the NAAPS and coincident cloud liquid effective radius retrievals from MODIS (cirrus contamination using CALIOP), we investigate the first aerosol indirect effect in Southeast Asia. We find that, as expected, aerosol loading anti-correlates with cloud effective radius, with maximum sensitivity in cumulous mediocris clouds with heights in the 3–4.5 km level. The highest susceptibilities in droplet effective radius to modeled perturbations in particle concentrations were found in the more remote and pristine regions of the western Pacific Ocean and Indian Ocean. Conversely, there was much less variability in cloud droplet size near emission sources over both land and water. We hypothesize this is suggestive of a high aerosol background already saturated with cloud condensation nuclei even during the relatively clean periods, in contrast to the remote ocean regions, which have periods where the aerosol concentrations are low enough to allow for larger droplet growth.
