Impact du traitement par hormone de croissance sur la composition corporelle et le métabolisme osseux d'enfants nés avec un retard de croissance intra-utérin

Le retard de croissance intra-uterin (RCIU) est defini par une taille et un poids inferieurs au P10 pour l'âge gestationnel. Il est caracterise, entre autre par une alteration de la croissance foetale aboutissant a une resistance a l'hormone de croissance (HC). Bien que la majorite des sujets presente un certain rattrapage en taille, certains developpent un retard de croissance ulterieur permanent. L'idee est donc nee de traiter ces sujets par haute dose d'HC biosynthetique. La question des risques d'un tel traitement s'est posee en raison de l'effet diabetogene de l'HC et des modifications qu'elle peut induire sur la masse maigre, la masse grasse et la densite osseuse. Le but de l'etude a ete d'evaluer l'impact sur la croissance et sur le volet metabolique. Dix enfants prepuberes ayant presente un RCIU sans croissance de rattrapage spontanee ont ete traites par HC recombinante a des doses supra physiologiques (53-67 g/kg/jour). La taille, le poids, la taille assise ont ete mesures et des dosages d'IGF1, IGFBP3, glycemie et insuline ont ete faits sur une base semestrielle alors qu'une densitometrie osseuse a ete faite annuellement sur une periode de 3 ans. Le gain en taille a ete spectaculaire (+ 1.78 DS), correspondant a plus de 10 cm (p < 0.001). Sous traitement, l'insulinemie et le HOMA ont augmente sans que ces augmentations soient significatives. La tolerance glucidique est restee dans la norme au prix d'une augmentation de la secretion d'insuline. La masse grasse a diminue alors que la masse maigre et la densite osseuse ont augmente de facon significative. Ces resultats correspondent aux travaux d'autres groupes. Il reste a demontrer que l'hyperinsulinisme transitoire induit par l'HC n'ait pas d'effet nefaste a long terme et en particulier sur le risque de developper ou aggraver un syndrome metabolique a l'âge adulte.
On the Chemistry of Cigar Smoke: Comparisons between Experimental Little and Large Cigars

Abstract Comparative data have been presented and evaluated on levels of various constituents in five different cigar tobaccos and in the smoke they generate when made into little and Iarge cigars. Generally the large cigars deliver a significantly lower level of mainstream smoke particulates such as TPM, nicotine and benzo[a]pyrene, when compared to the little cigars. On a per cigar basis, however, large cigars (as opposed to Iittle cigars) deliver substantially higher levels of CO and other gas phase constituents. A higher delivery of ammonia by large cigars is noted in the sidestream smoke. When little cigars are wrapped in cigarette paper, the major effects are lower levels of CO (reduced by 50 %). Cigar smoke can be distinguished from cigarette smoke on the basis of pH characteristics, ammonia and CO levels. Future studies should be concerned with establishing the material balance for components in mainstream and sidestream smoke of Iittle cigars and large cigars.

Orientation of channel carbonate ions in apatite: Effect of pressure and composition

Abstract X-ray structure and FTIR spectroscopy evidence is reviewed for two separate orientations of carbonate ions in the c-axis channel of carbonate apatite (CHAP) synthesized at high pressure and temperature: A1 carbonate has two O atoms close to the c-axis, whereas A2 carbonate has only one. The A2 orientation is reevaluated and its local structure refined using a rigid body model. A2 is the high-pressure configuration, but the A1 → A2 transformation is also dependent on bulk composition, especially the presence of type B carbonate. In the dry CaO-P2O5-CO2 system, the A1 → A2 transformation is initiated beyond about 4 GPa in type A CHAP compared with 1-2 GPa in A-B CHAP. Also, A2 carbonate is only weakly present in Na-bearing A-B CHAP synthesized at 0.5-1 GPa, which is assumed to be close to the threshold pressure for the transformation. The pressure stability of A2 is believed to be related to its central location in the channel and equitable distribution of bond distances to Ca2 cations in the channel wall (2.25 to 2.54 Å).
Effects of Grafting on Photosynthetic Characteristics of Potential Cd-Hyperaccumulator Solanum photeinocarpum under Cd Stress

A pot experiment was conducted to study the effects of grafting on photosyntheti c characteristics of potential Cd-hyperaccumulator Solanum photeinocarpum under Cd stress. Four treatments were used in the experiment: ungrafted (UG), self-rooted grafting by the same S. photeinocarpum seedling (SG), self-rooted grafting by two different sizes of S. photeinocarpu m seedlings (DG) and grafting on the rootstock of wild potato (PG). The results showed that SG and DG enhanced net photosynthetic rate (Pn) of S. photeinocarpum (Pn of DG was higher than SG), but PG decreased that. The light use efficiency (LUE) was the same as Pn. The grafting treatment decreased transpiration rate (Tr), stomatal conductance (Gs) and CO2 concentration of intercellular (Ci) of S. photeinocarpum, and increased water use efficiency (WUE) of S. photeinocarpum. Therefore, grafting could use to enhance the photosynthetic ability of Cd-hyperaccumulator S. photeinocarpum for the phytoremediation.
Thermal Conductivities of [EMIM][EtSO4], [EMIM][EtSO4] + C2H5OH, [EMIM][EtSO4] + H2O, and [EMIM][EtSO4] + C2H5OH + H2O at T = (283.15 to 343.15) K

The thermal conductivities of 1-ethyl-3-methylimidazol-3-ium ethylsulfate, 1-ethyl-3-methylimidazol-3-ium ethylsulfate + ethanol, 1-ethyl-3-methylimidazol-3-ium ethylsulfate + water, and 1-ethyl-3-methylimidazol-3-ium ethylsulfate + ethanol + water were reported. The measurements were performed in the temperature range from (283.15 to 343.15) K by a transient hot-wire technique covering the whole composition range at atmospheric pressure. The uncertainty of experimental thermal conductivity is 2.0 % with a coverage factor of k = 2. The second-order Scheffe polynomial was used to correlate the temperature and composition dependence of the experimental thermal conductivities for both binary and ternary mixtures. The average absolute deviation of those calculated values from the experimental data was 0.64 %.
Language, queerly phrased: a sociolinguistic examination of nonbinary gender identity in French

Language, a uniquely human skill, is intrinsic to the self. Beyond its base communication purpose, language serves to shape the identity of the speakers who use it. One of the biggest examples of language defining and confining interlocutors’ identities is the concept of gender. Based on a language’s use of gender, speakers of that language are confined to the gender rules set forth in grammatical systems. How then can people who do not identify as male or female be recognized as legitimate if the language they speak does not accommodate for their gender identity? This thesis aims to examine how gender variant people speak in gendered languages, first examining English, Hebrew and Japanese as case studies, then moving on to the historically rigid and regulated French. This study examines respondents’ proposed solutions to the French language’s lack of a non-gendered pronoun on social media to see if it is indeed possible for people to identify themselves and each other in a language that does not structurally recognize them as legitimate.
Performance Evaluation of an Organic Thin-Film Solar Cell of PTB7:PC71BM with an Alcohol-Soluble Polyelectrolyte Interlayer Prepared Using the Spray-Coating Method

We report the effect of a poly[(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctyl fluorene)] (PFN) interlayer on the performance of PTB7:PC71BM-based organic thin-film solar cells (OTFSCs) prepared using the spray-coating method. The active layer shows a broad absorption, but the effective contact area in the bulk hetrojunction (BHJ) is small because of the formation of aggregates on the surface. The surface aggregates dissolved by the addition of 1,8-diiodooctane (DIO) to the PTB7:PC71BM matrix, which results in an increase in the contact area between the donor and acceptor in the active layer and, thereby , an improvement in the device performance. The PFN interlayer enhances the charge-transport properties and suppresses exciton-recombination processes. This results in increases in the short-circuit current density (Jsc = 13.87 mA/cm2), open-circuit voltage (Voc = 0.747 V), and fill factor (FF = 57.97%), as a result of a high power conversion efficiency (PCE, η = 6.01%) compared .
Controlled release of ethylene via polymeric films for food packaging

In modern fruit supply chain a common method to trigger ripening is to keep fruits inside special chambers and initiate the ripening process through administration of ethylene. Ethylene is usually administered through cylinders with inadequate control of its final concentration in the chamber. The aim of this study is the development of a new technology to accurately regulate ethylene concentration in the atmosphere where fruits are preserved: a polymeric film, containing an inclusion complex of α-cyclodextrin with ethylene, was developed. The complex was prepared by molecular encapsulation which allows the entrapment of ethylene into the cavity of α-cyclodextrin. After encapsulation, ethylene can be gradually released from the inclusion complex and its release rate can be regulated by temperature and humidity. The inclusion complex was dispersed into a thin polymeric film produced by UV-curing. This method was used because is solvent-free and involves low operating temperature; both conditions are necessary to prevent rapid release of ethylene from the film. The polymeric films were characterized with respect to thermal behaviour, crystalline structure and kinetics of ethylene release, showing that can effectively control the release of ethylene within confined volume.
Electric-Submersible-Pump Performance under Methane/Water/Methane-Hydrate Pipe Flows

Pump performance of a submersible centrifugal type is investigated experimentally using a multiphase vertical flow loop. Methane in water is tested under turbulent bubbly pipe flows. Some tests are conducted at a three-phase equilibrium point of methane-water-methane hydrate. The pump is operated at 0.1 MPa and 3.9 MPa with void fractions up to 0.048. It is found that the pump performance is improved at higher pressures under vapor-liquid system but it is not significantly affected by the phase transformations. The results indicate that the fluid properties under the three-phase equilibrium and vapor-aqueous conditions are not very different.
Impacts of sulfur regulation in vivo on arsenic accumulation and tolerance of hyperaccumulator Pteris vittata

The impacts of the regulation of sulfur (S) metabolism in vivo on arsenic (As) and S species and on As accumulation by Pteris vittata L. were investigated using a synchrotron-based X-ray-absorption fine structure method. The S assimilation inhibitor l-buthionine-sulfoximine (BSO) markedly inhibited As reduction, doubling arsenate (As(V)) content in P. vittata rhizoids. The resulting As transport blockage in rhizoids, decreased As movement to aboveground tissues by 47%. The significant impact of BSO demonstrated the vital role of sulfhydryl groups ( SH) as reductants in As(V) reduction and confirmed the importance of SO (l-buthionine-sulfoximine) AS (O-acetyl-l-serine)
Examination of the mixing hypothesis as an explanation for elevated urinary CO2 tensions

To examine the adequacy of the mixing hypothesis as an explanation for high urinary CO2 tensions, urine-plasma pCO2 gradients were examined in normal subjects receiving NaHCO3 infusions in whom urinary buffer concentration was minimized by solute and water diuresis, antecedent carbohydrate diet and glucose infusions. U-P gradients varying from 23 to 78 mm Hg were generated in the face of minimal urinary buffer concentrations which varied from 1.40 to 2.95 mEq/l. Only by the most extreme assumptions, i. e. maximal heterogeneity and no back-diffusion of CO2, could the mixing hypothesis account for the observed gradients. Since these assumptions were highly improbable, it was concluded that the mixing hypothesis is not a tenable explanation of the high CO2 tension of alkaline urine.
Daily Tracker of Global Economic Activity: A Close-Up of the Covid-19 Pandemic

This paper develops a novel indicator of global economic activity, the GEA Tracker, which is based on commodity prices selected recursively through a genetic algorithm. The GEA Tracker allows for daily real-time knowledge of international business conditions using a minimum amount of information. We find that the GEA Tracker outperforms its competitors in forecasting stock returns, especially in emerging markets, and in predicting standard indicators of international business conditions. We show that an investor would have inexorably profited from using the forecasts provided by the GEA Tracker to weight his/her portfolio. Finally, the GEA Tracker allows us to present the daily evolution of global economic activity during the COVID-19 pandemic.
Articles : Validation of High-Performance Liquid Chromatography Analysis on Phenolic Substances of Cirsium setidens and Sedative Effect of Pectolinarin as the Active Principle

This study was performed to determine the composition of phenolic substances contained in the leaves of Cirsium setidens (Compositae), validate the high-performance liquid chromatography (HPLC) method, and determine the in vivo sedative effect of the main component pectolinarin. Six phenolic compounds isolated from C. setidens were spectroscopically identified as chlorogenic acid (1), hyperoside (2), 3,4-di-O-caffeoylquinic acid (3), caffeic acid methyl ester (4), linarin (5), and pectolinarin (6) and then used as standard compounds for HPLC analysis. HPLC proved to be precise, accurate, and sensitive for the simultaneous analysis of the phenolic substances. In particular, six compounds showed good regression (R2 > 0.999) within test ranges and recovery was in the range of 95.4 - 104.8%. The content of pectolinarin was considerably higher (156.48 mg/g) than those of other phenolic substances including the other flavone glycoside, linarin (18.99 mg/g). The contents of other phenolic substances, in order, were chlorogenic acid (8.41 mg/g), 3,4-di-O-caffeoylquinic acid (5.74 mg/g), hyperoside (4.33 mg/g), and caffeic acid methyl ester (0.51 mg/g). Oral administration with compound 6 (10 and 20 mg/kg) enhanced the sleeping time induced by pentobarbital in mice, indicating that it has a sedative effect.
Three-dimensional correlated-fermion phase separation from analysis of the geometric mean of the individual susceptibilities

A quasi-Gaussian approximation scheme is formulated to study the strongly correlated imbalanced Fermions thermodynamics, where the mean-field theory is not applicable. The non-Gaussian correlation effects are understood to be captured by the statistical geometric mean of the individual susceptibilities. In the three-dimensional unitary fermions ground state, a universal nonlinear scaling transformation relates the physical chemical potentials with the individual Fermi kinetic energies. For the partial polarization phase separation to full polarization, the calculated critical polarization ratio is δC = [1-(1-ξ)6/5]/[1+(1-ξ )6/5] 0.34. ξ = 4/9 gives the ratio of the symmetric ground state energy density to that of the ideal fermion gas.

Aerial Respiration in the Banded Knife Fish Gymnotus carapo (Teleostei: Gymnotoidei)

This anatomical and experimental study has revealed that the banded knife fish Gymnotus carapo is capable of air breathing by means of the highly specialized, enlarged, and vascularized posterior chamber of the gas bladder. Air ventilation is accomplished by the action of a uniquely specialized esophageal force pump. Cineradiography has shown that air ventilation proceeds in a consistent sequence, with an inhalation followed by two or more exhalations. It is postulated that prior inhalation raises the pressure within the gas bladder temporarily as a preliminary step to passive exhalation of air by hydrostatic pressure via a relatively narrow and long pneumatic duct. At temperatures of 29-31 C Gymnotus extracts 1.63, 1.12, and 0.76 mmol O₂ h⁻¹ kg⁻¹ from air (Ṁao2) when it is in air-equilibrated water at 47%, 72%, and 95%, respectively, of air at STP. The amounts of oxygen extracted from water (Ṁwo2) are, respectively, 0.56, 1.03, and 1.33 mmol O₂ h⁻¹ kg⁻¹. Total Ṁo2 between 95% and 47% normoxia in water is 2.23 ± 0.17 mmol O₂ h⁻¹ kg⁻¹. When Po2 of water is higher than 200 torr the fish can rely on water breathing, but when Po2 is below 60 torr it relies on air. When Gymnotus has no access to air, it is able to lower its total O₂ consumption to 69% of the control Mo2 at a temperature of 29 C. Aquatic respiration increases with higher O₂ levels in water, lower temperatures, and when access to air is either hindered or prohibited, while aerial respiration increases under the opposite conditions.
Herramientas para el monitoreo y sistema de alerta de floraciones de cianobacterias nocivas: Río Uruguay y Río de la Plata

Las floraciones de cianobacterias potencialmente toxicas es uno de los problemas mas difundidos en los sistemas acuaticos a nivel global. Sin embargo, no existen programas de monitoreo sensibles y directamente aplicables a la prediccion de las floraciones y su gestion. Con este objetivo se combinaron conceptos ecologicos y geneticos para generar herramientas para el monitoreo de cianobacterias. Se utilizaron dos aproximaciones: agrupacion de organismos en grupos funcionales basados en morfologia y analisis moleculares (PCR cuantitativo en tiempo real) que indican presencia de genes que codifican para la expresion de cianotoxinas (mcy). Para evaluar las herramientas se realizaron seis campanas de muestreo bimensuales (2013-2014) en seis estaciones con dos sitios en cada una, a lo largo del Rio Uruguay y del Estuario Rio de la Plata, desde Salto Grande hasta Punta del Este. Se observo un gradiente marcado en las variables meteorologicas, fisico-quimicas, y mayores abundancias de organismos planctonicos en Salto Grande y Punta del Este. Se encontro la presencia en todo el gradiente de poblaciones toxicas, con mayor abundancia en Salto, particularmente del complejo Microcystis aeruginosa (CMA). Las variables ambientales mas importantes en determinar el gradiente ambiental y las variaciones en las variables biologicas fueron la salinidad, la temperatura, el viento y la turbidez. Los resultados de los nuevos indicadores (presencia en red del CMA y genes mcy) coincidieron con los tradicionales (ej. clorofila-a) en los casos de floraciones mas severas, y ambos fueron sustantivamente mas sensibles en situaciones de bajas abundancias. La conjuncion de los resultados se aplico a la construccion de un protocolo de monitoreo y un sistema de alerta.
Scanning Electron Microscopic Examination of Different Varieties of Oat Grains in Comparison with the Analyzed Degree of Starch Breakdown and Glycaemic Responses in Horses

Starch granules of different varieties of oat grains were observed by a scanning electron microscope (SEM) in order to provide information about morphologic characteristics e.g. the surface and interconnections of the granules to evaluate a possible enzyme attack and degradation, respectively. Additional information about the analyzed degree of starch breakdown and the glycaemic responses in horses after feeding the oat grains were used as parameters for comparison. The SEM has been used as an effective tool in determination of shapes and surface structures of various starch granules, in particular the description of differences within one variety.
