  2. The new "genetico-racial" skin classification: maximizing the safety of skin treatments for Asians.

    Racial genetics play a significant role in determining a patient's response to any skin treatment. Contrary to traditional skin classifications, the new genetico-racial classification takes into consideration the racial origins of patients, as manifested in both their skin color and their feature contour characteristics, rather than their skin color alone. According to this new classification, patients may belong to 1 of 6 categories, originating from the 3 ancient continents: Africa, Europe, and Asia. In this article the Asian category, as well as its subcategories, are approached in a radically different way. This new geneticoracial classification ushers in a "paradigm shift" in the way Asian patients are perceived before, during, and after skin treatments. The new geneticoracial classification advances that Asians are excellent candidates to most peels and laser treatments, as long as their genetic disposition and their anticipated responses to those treatments are understood and respected.

    Ependymal tumors constitute a clinicopathologically heterogeneous group of brain tumors. They vary in regard to their age at first symptom, localization, morphology and prognosis. Genetic data also suggests heterogeneity. We define a newly recognized subset of ependymal tumors, the trisomy 19 ependymoma. Histologically, they are compact lesions characterized by a rich branched capillary network amongst which tumoral cells are regularly distributed. When containing clear cells they are called clear cell ependymoma. Most trisomy 19 ependymomas are supratentorial WHO grade III tumors of the young. Genetically, they are associated with trisomy 19, and frequently with a deletion of 13q21.31-31.2, three copies of 11q13.3-13.4, and/or deletions on chromosome 9. These altered chromosomal regions are indicative of genes and pathways involved in trisomy 19 ependymoma tumorigenesis. Recognition of this genetico-histological entity allows better understanding and dissection of ependymal tumors. PMID:17626628

    The popular skin classifications, notably the ‘Fitzpatrick’ and ‘Obaji’ classifications, are primarily based on skin colour. Other criteria are occasionally considered, such as the degree of skin oiliness, thickness, sensibility, etc. Although these classifications are easy to understand and apply, their simplicity limits their precision, sophistication and applicability. The new genetico-racial skin classification proposed herein suggests that skin response to any peel or laser treatment is genetically programmed and is, therefore, linked to the genetic and racial origin of the patient. In other words, in addition to skin colour, the patient’s facial features and ancestry should be taken into account when classifying any skin. The new genetico-racial skin classification enables the physician to determine with great precision, and before any peel or laser treatment, the level of the patient’s suitability and the expected postoperative outcomes; therefore, reducing the likelihood of complications.

    This paper reports on a study of the G-6-PD deficiency in Bragança Paulista, São Paulo State, Brazil. A total of 4,621 male blood donors were investigated over a 36-month period. Of these, 80 had the G-6-PD deficiency. Molecular analysis was performed on 70 unrelated G-6-PD deficients through DNA amplification followed by digestion with restriction enzymes and single strand conformation polymorphism analysis (SSCP). In 98.6%, the G-6-PD A- (202 G<--A) mutation was observed through digestion of exon 4 with Nla III. The presence of an uncommon mutation in exon 9 was also observed through SSCP. No case of the Mediterranean variant was observed. These results indicate that the A- (202G<--A) variant, almost exclusive, was introduced into the community not only by individuals of African origin, but also by European immigrants, mainly Italian, Spanish, and Portuguese. The Italian contribution in terms of the G-6-PD Mediterranean variant was smaller than its contribution to beta thalassemia, probably due to the Northern Italian origin of these immigrants.

    The operational use of Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann), genetic sexing strains in Sterile Insect Technique applications can be maximized by developing methods for effective shipment of eggs. This would enable a central production facility to maintain the relevant mother stocks and large colonies to supply eggs to satellite centers that would mass produce only males for irradiation and release. In order to achieve this, the survival of medfly embryos of different ages was assessed after storage at 5, 10, 15, 20, and 25 deg. C in water for different periods of time. Survival was affected by all 3 variables, i.e., embryo age, water temperature, and length of storage. Storage of embryos at any temperature for 120 h resulted in almost no survival. Controlling the age of the embryo at the time of the temperature treatment is crucial for the success of this procedure. Embryos collected between 0 to 12 h after oviposition and pre-incubated at 25 deg. C for 12 h provide a suitable 72 h window for shipment when maintained between 10 to 15 deg. C. Under these conditions, no significant reductions in survival during all the developmental stages were observed. (author) [Spanish] El uso operacional de cepas de la mosca del mediterraneo Ceratitis capitata (Wiedemann) en las cuales es posible separar los sexos a traves de mecanismos geneticos para su utilizacion en la Tecnica del Insecto Esteril (TIE), puede ser maximizado con el desarrollo de metodos efectivos para el envio y transporte de huevos. Esto permite que un laboratorio de produccion centralizada mantenga las respectivas colonias responsables por la produccion de huevos para este abastecer laboratorios satelites responsables por la produccion masiva de solamente machos para subsiguiente irradiacion y liberacion. Para ser posible esta alternativa fue evaluada la supervivencia de embriones de diferentes edades despues de su almacenamiento en agua a 5, 10, 15, 20 y 25 deg. C por diferentes periodos de tiempo. La supervivencia fue afectada por las 3 variables evaluadas, la edad del embrion, la temperatura del agua y el periodo de almacenamiento. El almacenamiento de los embriones a cualquier temperatura por 120 horas dio como resultado la casi no supervivencia. Una edad controlada de los embriones a tratar es crucial para el exito de este protocolo. Embriones colectados entre 0 a 12 horas despues de la oviposicion y su previa incubacion a 25 deg. C por 12 horas brinda un margen de hasta de 72 horas de duracion del almacenamiento y transporte, siempre y cuando estos se mantengan en una temperatura de entre 10 a 15{sup o}C. En estas condiciones, fue registrada una reduccion no significante de la supervivencia de los diferentes estados de desarrollo. (author)

    Conforme aumenta la edad de la población, la coexistencia de dos o más enfermedades en un mismo paciente deja de ser la excepción y se convierte casi en una regla. Para definirlo se ha empleado el vocablo comorbilidad, y las enfermedades se llaman comórbidas. Es posible que estos términos no estén muy bien construidos en español y que no sean más que traducciones del inglés, pero, aunque se han utilizado alternativas tales como polimorbilidad, multimorbilidad, polipatía, enfermedades múltiples, enfermedades multifactoriales, enfermedades complejas, pluripatología y enfermedades asociadas o coexistentes, lo cierto es que el término comorbilidad ya se ha consagrado. La Organización Mundial de la Salud (OMS) lo ha aceptado, en referencia sobre todo al ámbito psiquiátrico, cuando en un mismo individuo coexisten un trastorno inducido por el consumo de una sustancia psicoactiva y un trastorno psiquiátrico.

    We present numerical solutions to both the standard and modified two-dimensional Fokker-Planck equations with adiabatic focusing and isotropic pitch-angle scattering. With the numerical solution of the particle distribution function, we then discuss the related numerical issues, calculate the parallel diffusion coefficient using several different methods, and compare our numerical solutions for the parallel diffusion coefficient to the analytical forms derived earlier. We find the numerical solution to the diffusion coefficient for both the standard and modified Fokker-Planck equations agrees with that of Shalchi for the mean squared displacement method of computing the diffusion coefficient. However, we also show the numerical solution agrees with that of Litvinenko and Shalchi and Danos when calculating the diffusion coefficient via the velocity correlation function.

    Una de las principales aplicaciones actuales de los procesos de disociación multifotónica inducidos por radiación láser infrarroja (DMI) es la producción de radiales libres, con el fin de estudiar sus propiedades cinéticas y espectroscópicas. La disociación de moléculas poliatómicas en el IR con láseres de CO2 tiene lugar desde la superficie de energía molecular mas baja y conduce generalmente a la formación de fragmentos en el estado electrónico fundamental, con diversos grados de excitación vibracional. En el Grupo de Procesos Multifotónicos del Instituto de Estructura de la Materia del C.S.I.C. hemos puesto a punto la técnica de Fluorescencia Inducida por Láser (LIF) para la detección y análisis en tiempo real de los fragmentos producidos en la DMI inducida mediante uno o dos campos láseres de diferentes longitudes de onda. Objetivos de nuestro trabajo han sido el estudio de los canales de disociación mayoritarios y de las especies transitoria producidas, así como de la distribución de energía interna con que éstas son generadas. En particular hemos detectado mediante LIF las especies: C2, CF, CH, SiH2, CF2, CH2, SiHCl, y CF3 a partir de la disociación de, entre otras, las siguientes moléculas: C2H3Br, C3F6, C4H8Si, C2H5ClSi y CH5ClSi. En este trabajo presentamos algunos de los resultados obtenidos mediante el estudio por LIF de estos radicales: estudio temporal de la señal LIF obtenida con determinación de tiempos de vida, espectros de excitación y fluorescencia, temperaturas vibracionales de formación, variación de la intensidad LIF con el tiempo de retraso entre los láseres de disociación y prueba, etc.

    An open-field experiment was conducted to assess the suitability of the South American leaf feeding beetle Gratiana boliviana Spaeth for biological control of Solanum viarum Dunal in the USA. An open-field test with eggplant, Solanum melongena L., was conducted on the campus of the University of Buenos Aires, Argentina, and a S. viarum control plot was established 40 km from the campus. One hundred adult beetles were released in each plot at the beginning of the experiment during the vegetative stage of the plants, and forty additional beetles were released in the S. melongena plot at the flowering stage. All the plants in each plot were checked twice a week and the number of adults, immatures, and eggs recorded. Results showed almost a complete rejection of eggplant by G. boliviana. No noticeable feeding damage was ever recorded on eggplant. The experiment was ended when the eggplants started to senesce or were severely damaged by whiteflies and spider mites. The results of this open-field experiment corroborate previous quarantine/laboratory host-specificity tests indicating that a host range expansion of G. boliviana to include eggplant is highly unlikely. Gratiana boliviana was approved for field release in May 2003 in the USA. To date, no non-target effects have been observed either on eggplant or native species of Solanum.

Cien escarabajos adultos fueron liberados en cada parcela al inicio del experimento durante la fase vegetativa, y cuarenta escarabajos adicionales fueron liberados en la parcela de berenjena durante la floracion. Todas las plantas en cada parcela fueron inspeccionadas dos veces a la semana y el numero de adultos, larvas, y posturas fueron registrados. Resultados indicaron un casi completo rechazo de la berenjena por G. boliviana. Ningun dano visible de defoliacion en la berenjena fue detectado. Las pruebas concluyeron cuando las plantas de berenjena alcazaron su madurez o fueron severamente danadas por mosca blanca y acaros. Resultados corroboran previas pruebas de especificidad en laboratorio/cuarentena que indican que la berenjena no es un hospedero de G. boliviana y que la posibilidad de llegar a ser una plaga de este cultivo es muy remota.

    A rapid, simple, and sensitive immunochromatographic test strip has been developed for testing residues of ciprofloxacin (CIP). A specific and sensitive monoclonal antibody (mAb) for CIP was generated by immunizing BALB/c mice with well-characterized CIP-Keyhole limpet haemocyanin. Under the optimized conditions, the cut-off limits of test strips for CIP were found to be 5 ng/mL in phosphate-buffered saline and 2.5 ng/mL in milk samples. Each test can be evaluated within 3 min. The cross-reactivities of the CIP test strip to enrofloxacin (ENR), norfloxacin (NOR), nadifloxacin (NDF), danofloxacin (DANO), pefloxacin (PEX), lomefloxacin (LOME), enoxacin (ENO), and sarafloxacin (SAR) were 71.4%, 71.4%, 66%, 50%, 33%, 20%, 12.5%, and 6.25%, respectively. The data indicate that the method is sensitive, specific, and has the advantages of simplicity and speed, therefore, this test strip is a useful screening method for the detection of CIP residues in milk samples.

If the interaction between two quartets is weak in given states, such states are concluded to be well represented by a quartet structure. In this paper, we study the quartet structure of eight valence nucleons in two cases. The first is a single j shell, demonstrating that the so-called stretch scheme [M. Danos and V. Gillet, Phys. Rev. Lett. 17, 703 (1966), 10.1103/PhysRevLett.17.703] is very good for low-spin states with a quadruple-quadruple interaction, and is reasonably good under realistic interactions. The second case is the ground state of 92Pd in the p1 /2p3 /2f5 /2g9 /2 shell with the JUN45 effective interaction. We show that the quartet correlation is essential in the ground state of 92Pd.

    Objectives Describe the diagnoses and the time to recovery of running-related injuries in novice runners. Design Prospective cohort study on injured runners. Method This paper is a secondary data analysis of a 933-person cohort study (DANO-RUN) aimed at characterizing risk factors for injury in novice runners. Among those sustaining running-related injuries, the types of injuries and time to recovery is described in the present paper. All injured runners were diagnosed after a thorough clinical examination and then followed prospectively during their recovery. If they recovered completely from injury, time to recovery of each injury was registered. Results A total of 254 runners were injured. The proportion of runners diagnosed with medial tibial stress syndrome was 15%, 10% for patellofemoral pain, 9% for medial meniscal injury, 7% for Achilles tendinopathy and 5% for plantar fasciitis. Among the 220 runners (87%) recovering from their injury, the median time to recovery was 71 days (minimum ?=?9 days, maximum ?=?617 days). Conclusions Medial tibial stress syndrome was the most common injury followed by patellofemoral pain, medial meniscal injury and Achilles tendinopathy. Half of the injured runners were unable to run 2×500 meters without pain after 10 weeks. Almost 5% of the injured runners received surgical treatment. PMID:24923269

    In measurement-based quantum computation (MBQC), elementary quantum operations can be more parallelized than the quantum circuit model by employing a larger Hilbert space of graph states used as the resource. Thus MBQC can be regarded as a method of quantum computation where the temporal resource described by the depth of quantum operations can be reduced compared to the quantum circuit model by using the extra spatial resource described by graph states. To analyze the trade-off relationship of the spatial and temporal resources, we consider a method to obtain quantum circuit decompositions of general unitary transformations represented by MBQC on graph states with a certain underlying geometry called generalized flow. We present a method to translate any MBQC with generalized flow into quantum circuits without extra spatial resource. We also show an explicit way to unravel acausal gates without postselection that appear in the quantum circuit decomposition derived by a translation method [V. Danos and E. Kashefi, Phys. Rev. A 74, 052310 (2006), 10.1103/PhysRevA.74.052310] and that represents an effect of the reduction of the temporal resource in MBQC. Finally, by considering a way to deterministically simulate these acausal gates, we investigate a general framework to analyze the trade-off between the spatial and temporal resources for quantum computation.

    Low-level processes of children's written language production are cognitively more costly than those involved in speaking. This has been shown by French authors who compared oral and written memory span performance. The observed difficulties of children's, but not of adults' low-level processes in writing may stem from graphomotoric as well as from orthographic inadequacies. We report on five experiments designed to replicate and expand the original results. First, the French results were successfully replicated for German third-graders, and for university students. Then, the developmental changes of the cognitive costs of writing were examined during primary school, comparing the performance of second- and fourth-graders. Next, we show that unpractised writing modes, which were experimentally induced, also lead to a decrease of memory performance in adults, which supports the assumption that a lack of graphomotoric automation is responsible for the observed effects in children. However, unpractised handwriting yields clearer results than unpractised typing. Lastly, we try to separate the influences of graphomotoric as opposed to orthographic difficulties by having the words composed through pointing on a "spelling board". This attempt, however, has not been successful, probably because the pointing to letters introduced other low-level costs. In sum, throughout the four years of primary school, German children show worse memory span performance in writing compared to oral recall, with an overall increase in both modalities. Thus, writing had not fully caught up with speaking regarding the implied cognitive costs by the end of primary school. Therefore, conclusions relate to the question of how to assess properly any kind of knowledge and abilities through language production. Los procesos de bajo nivel en la producción de lenguaje escrito en niños son más costosos a nivel cognitivo que los que están implicados en el habla. Esto ha sido demostrado por autores franceses quiénes compararon la ejecución en la capacidad de retención en la memoria oral y escrita. Las dificultades observadas en niños, pero no en adultos, en procesos de bajo nivel en la escritura pueden derivarse de la inadecuación grafomotriz u ortográfica. Informamos sobre cinco experimentos diseñados para replicar y ampliar los resultados originales. Primero, los resultados franceses fueron replicados con éxito para alemanes en tercer curso y para estudiantes universitarios. Después, los cambios evolutivos en costes cognitivos en la escritura fueron estudiados durante la educación primaria, comparando la ejecución de los alumnos del segundo y cuarto curso. Posteriormente, demostramos que las formas de escribir no practicadas, que se han inducido experimentalmente, conducen a la disminución de la ejecución en la memoria también en adultos, lo cual apoya la hipótesis de que la falta de la automatización grafomotriz es la responsable de los efectos encontrados en niños. Sin embargo, la escritura a mano muestra resultados más claros que la escritura a máquina. Por último, hemos intentado separar la influencia de la grafomotricidad frente a las dificultades ortográficas componiendo las palabras señalando en una "pizarra de ortografía". Este intento, sin embargo, no ha tenido éxito, probablemente porque señalar letras ha introducido otros costes de bajo nivel. Resumiendo, a lo largo de los cuatro años de la educación primaria, los niños alemanes muestran peor ejecución en retención en memoria en la escritura, en comparación con el recuerdo oral, con un incremento general en ambas modalidades. Por tanto, al final de la educación primaria, la escritura no ha igualado todavía el habla en cuanto a los costes cognitivos. Por consiguiente, las conclusiones están relacionadas con la cuestión de cómo evaluar cualquier tipo de conocimiento o habilidades mediante la producción de lenguaje. Les processus de bas niveau de la production du langage écrit chez les enfants sont cognitivement plus coûteux que ceux impl

    Type XIII collagen is a type II transmembrane protein with three collagenous (COL1-3) and four noncollagenous domains (NC1-4). The human alpha1(XIII) chain contains altogether eight cysteine residues. We introduced point mutations to six of the most N-terminal cysteine residues, and we show here that the two cysteines 117 and 119 at the end of the N-terminal noncollagenous domain (NC1) are responsible for linking the three alpha1(XIII) chains together by means of interchain disulfide bonds. In addition, the intracellular and transmembrane domains have an impact on trimer formation, whereas the cysteines in the transmembrane domain and the COL1, the NC2, and the C-terminal NC4 domains do not affect trimer formation. We also suggest that the first three noncollagenous domains (NC1-3) harbor repeating heptad sequences typical of alpha-helical coiled-coils, whereas the conserved NC4 lacks a coiled-coil probability. Prevention of the coiled-coil conformation in the NC3 domain is shown here to result in labile type XIII collagen molecules. Furthermore, a new subgroup of collagenous transmembrane proteins, the Rattus norvegicus, Drosophila melanogaster, and Caenorhabditis elegans colmedins, is enlarged to contain also Homo sapiens collomin, and Pan troglodytes, Mus musculus, Tetraodon nigroviridis, and Dano rerio proteins. We suggest that there is a structurally varied group of collagenous transmembrane proteins whose biosynthesis is characterized by a coiled-coil motif following the transmembrane domain, and that these trimerization domains appear to be associated with each of the collagenous domains. In the case of type XIII collagen, the trimeric molecule has disulfide bonds at the junction of the NC1 and COL1 domains, and the type XIII collagen-like molecules (collagen types XXIII and XXV) and the colmedins are similar in that they all have a pair of cysteines in the same location. Moreover, furin cleavage at the NC1 domain can be expected in most of the proteins. PMID:17344215

    The intensity scales determined the damage caused by an earthquake. However, a new methodology takes into account not only the damage but the type of damage "Earthquake Archaeological Effects", EAE's, and its orientation (e.g. displaced masonry blocks, conjugated fractures, fallen and oriented columns, impact marks, dipping broken corners, etc.) (Rodriguez-Pascua et al., 2011; Giner-Robles et al., 2012). Its main contribution is that it focuses not only on the amount of damage but also in its orientation, giving information about the ground motion during the earthquake. Therefore, this orientations and instrumental data can be correlated with historical earthquakes. In 2011 an earthquake of magnitude Mw 5.2 took place in Lorca (SE Spain) (9 casualties and 460 million Euros in reparations). The study of the EAE's was carried out through the whole city (Giner-Robles et al., 2012). The present study aimed to a.- validate the EAE's methodology using it only in a small place, specifically the cemetery of San Clemente in Lorca, and b.- constraining the range of orientation for each EAE's. This cemetery has been selected because these damage orientation data can be correlated with instrumental information available, and also because this place has: a.- wide variety of architectural styles (neogothic, neobaroque, neoarabian), b.- its Cultural Interest (BIC), and c.- different building materials (brick, limestone, marble). The procedure involved two main phases: a.- inventory and identification of damage (EAE's) by pictures, and b.- analysis of the damage orientations. The orientation was calculated for each EAE's and plotted in maps. Results are NW-SE damage orientation. This orientation is consistent with that recorded in the accelerometer of Lorca (N160°E) and with that obtained from the analysis of EAE's for the whole town of Lorca (N130°E) (Giner-Robles et al., 2012). Due to the existence of an accelerometer, we know the orientation of the peak ground acceleration and we have been able to constrain the ranges of orientation for each EAE's. The orientation of the damage is not usually recorded after an earthquake; however, it can provide information on seismic source in historical earthquakes. References Giner-Robles, J.

    Geological records contain a wealth of information about accretionary episodes in the life of a coastal profile, such as age and type of the deposits and circumstances during which the accretion took place; of erosional events mainly the final limit of the erosion and circumstances under which the erosion took place can be estimated. To obtain a more complete picture of the events shaping the sedimentary record and transport processes involved, process-based modelling can be a useful tool (e.g. Apotsos et al., 2011). However, application of such modelling to different types of events remains a challenge. In our presentation we intend to show examples of the effects of different events on the stratigraphic record and to discuss the challenges related to the modelling of each of these types of events. The test site chosen is the Costa da Caparica, south of Lisbon, Portugal. The stratigraphic record and progradation rates of the coastal were obtained combining geophysical (Ground Penetrating Radar) and dating (Optically Stimulating Luminescence) techniques, which document very recent ages for the preserved coastal barrier. Within the record, we focus on a period around the big tsunami of 1755, during which the shoreline experienced a long-term prograding trend with evidence of severe erosion events. Rather than trying to exactly reproduce the stratigraphy observed here, we will carry out exploratory simulations to create 'building blocks' of stratigraphy related to the different types of events, which we can loosely compare with observations reported in Rebelo et al. (2013). The model applied for all simulations is XBeach (Roelvink et al., 2009), which is used in three different modes (no short waves, time-varying wave action balance, stationary wave action balance, respectively) to accommodate the impact of tsunamis, storms, and average conditions; for the latter we include the dune and associated processes in a simplified aeolian transport and response model. In all cases we resolve wave-averaged flows, bed load and suspended load transport and morphology change including avalanching. Results will be presented in terms of both profile change and resulting contribution to stratigraphy, allowing to evaluate the effects of these different building blocks on the stratigraphic record.
