On May 4 2013, Pluto passed in front of a 14 star and the shadow was well observed from multiple occultation groups. This paper presents results from the three light curves observed at Las Cumbres Observatory Global Telescope Network (LCOGT) from their Cerro Tololo site. The three LCOGT telescopes have 1.0 m apertures and used identical frame-transfer cameras. The cameras currently have a 2 second readout time therefore autonomous observations were scheduled with different exposure times to give good time resolution of the event. We will present results of this occultation and compare occultation results from 1988 to 2013 with volatile transport models. [less ▲]

After more than two decades of fieldwork in the Maya archaeological site of Calakmul, Mexico, numerous remnants of blue and green pigments have been reported on wall paintings, as well as on funerary paraphernalia, such as masks, miniatures and vases. The importance of these pigments is linked to the sacred values that Maya people associate with blue and green colours since pre-Columbian times. These hues symbolise water, and are therefore associated with fertility and regeneration. This paper aims to perform a survey of the blue and green pigments used in the Early Classic and Late Classic periods in Calakmul (300-850 A.D.), in order to have a better understanding of their chemical composition and origin. Analyses were performed on microsamples using Raman and UV-visible spectroscopies to evaluate the possibilities that these techniques can offer in future in situ researches on Mesoamerican archaeological materials and objects. With these analyses, we have documented a large blue-green chromatic palette, which includes the earliest Blue Maya and Green Maya known to date, as well as malachite, pseudomalachite and an unknown-up-to-now blue-green mineral pigment, veszelyite, used specifically for ritual objects. The results indicate a careful selection of imported products and the mastering of a complex ancient Maya pictorial tradition. Copyright (c) 2008 John Wiley & Sons, Ltd. [less ▲]

A compound drop is made of a millimetric water drop encapsulated by an oil shell. They are obtained by merging one drop of each component (water and oil). Afterwards, they are laid on a high viscosity oil bath which is vertically vibrated. When the forcing acceleration is higher than a given threshold, compound drops can bounce on the surface. We show that above a second threshold some oil contained in the shell enters in the inner water droplet. In a second experiment, we drop the compound droplet on the oil bath at rest. We can determine the range of impact speed in which capillary waves developed on the surface are able to generate an oil drop (coming from the shell) in the water drop. When the bouncing trajectories of the droplets are analyzed a correlation between the emulsion threshold and the static analysis can be made. [less ▲]

Compound drops are made of a millimetric water drop encapsulated by an oil shell. They are laid on a high viscosity oil bath which is vertically vibrated. When the forcing acceleration is higher than a given threshold, compound drops can bounce on the surface. We show that above an another threshold a double emulsion occurs in the drop. We measured this emulsion threshold for various size and water/oil volume ratio of the compound drop. [less ▲]

Mazindol, a drug that blocks the reuptake of dopamine, was studied in the treatment of Parkinson's disease in both a pilot study (12 patients) and a controlled trial (11 patients). The patients had stage II or III disease, according to the classification of Hoehn and Yahr. Both studies showed that mazindol possessed anti-parkinsonian properties and that the improvement was statistically significant. The therapeutic effect was moderate, but could be of value for patients in the early stages of the disease. The drug was well tolerated; only two patients had side effects. [less ▲]

Context: McCune Albright syndrome (MAS) is a clinical association of endocrine and non-endocrine anomalies caused by post-zygotic mutation of the GNAS1 gene, leading to somatic activation of the stimulatory alpha subunit of G protein (Gsalpha). Important advances have been made recently in describing pathological characteristics of many MAS-affected tissues, particularly pituitary, testicular and adrenal disease. Other rarer disease related features are emerging. Objective: To study pathological and genetic findings of MAS on a tissue-by-tissue basis in classically and non classically affected tissues. Design: A comprehensive autopsy and genetic analysis Setting: Tertiary referral University Hospital Patients: Adult male patient with MAS and severe disease burden including gigantism Intervention(s): Clinical, hormonal and radiographic studies; gross and microscopic pathology analyses, conventional PCR and droplet digital PCR analyses of affected and non affected tissues Main Outcome Measure: Pathological findings, presence of GNAS1 mutations Results: The patient was diagnosed with MAS syndrome at six years of age based on the association of cafe-au-lait spots and radiological signs of polyostotic fibrous dysplasia. Gigantism developed and hyperprolactinemia, hypogonadotropic hypogonadism and hyperparathyroidism were diagnosed throughout adult period. The patient died at the age of 39 from pulmonary embolism. A detailed study revealed mosaiscism for the p.R201C GNAS mutation distributed across many endocrine and non-endocrine tissues. These genetically implicated tissues included rare or previously undescribed disease associations including primary hyperparathyroidism, and hyperplasia of the thymus and endocrine pancreas. Conclusions: This comprehensive pathological study of a single patient highlights the complex clinical profile of MAS and illustrates important advances in understanding the characteristics of somatic GNAS1 related pathology across a wide range of affected organs.

In the conception of the building envelope, the sketch design is a crucial moment of the architectural design. The first drawing gives a concrete expression to the project author's first choices regarding a set of requirements and preferences, as expressed by the multiple stakeholders of the project, namely: the building owner, users, public authorities and the design team surrounding the architect. The present study explores a Multiple Criteria Decision Aid procedure (MCDA), an aid to help stakeholders improve this stage of the sketch design. The methodology is built close to the usual design process. This paper presents design and decision aid intertwined procedures and briefly describes the softwares involved: AMCE and EsQUIsE. The decision aid process is a first attempt to address this architectural sketch design challenge. The reader is expected to react to the suggested presentation of this still open MCDA problem.

Membrane proteins (MP) play an important role in biological processes. Isolation and quantification of these MP using classical techniques is often limited due to their poor solubility and relatively low abundance. These membrane proteins enclosed markers which could be potential therapeutic targets. These potential therapeutic targets have to be accessible to antibodies and need to be presented in the plasmic membrane. Assays were conducted on MCF-7 / BOS cell line, immortal and easier to cultivate. The goal of this work is to obtain an enriched membrane fraction to facilitate the analysis of the sample and to simplify the complex proteins mixture. To isolate transmembrane proteins, we compared two methods. The first one used different extraction cycles characterized by different buffers to isolate membrane proteins. The second method labelled accessible extracellular domains at the surface of MCF-7 cells with biotin prior to differential centrifugation. The obtained enriched membrane proteome was digested with trypsin and/or Lysyl Endopeptidase. Obtained peptides were separated by 2D-HPLC chromatography and on-line analysed ion trap mass spectrometer, the Esquire HCT. [less ▲]

Membrane proteins play an important role in biological processes but their isolation and quantification using classical techniques is often limited due to their poor solubility and relatively low abundance. These membrane markers have to be accessible to antibodies and should be potential therapeutic targets. The tests were conducted on MCF-7 / BOS cell line, immortal and easier to cultivate. The goal of this work is to obtain a pure membrane fraction to facilitate the analysis of the sample. To isolate transmembrane proteins, we compared two methods. The first one used different extraction cycles characterized by different buffers to isolate membrane proteins.
