  1. The Physical Effects of Contact and Close-Distance Gunfire on Sweatshirt Fleece.

    Kusluski, Michael A

    2018-05-01

    Powder stippling caused by the impact of propellant particles during close-distance gunfire has been previously described on skin and solid objects only. Additionally, radial tearing has been described as clear evidence of a contact-distance shot, requiring no further testing. Patterns of discrete perforating holes (referred to here as "stippling perforations") and other physical damage on sweatshirt fleece fabrics were prepared. Using the firearm and ammunition in this study, stippling perforations were observed to a maximum muzzle-to-target distance of 35 cm (10 inches). In addition, radial tearing and disintegration were present (and often more extensive) at greater than contact distance. The presence of stippling perforations could augment muzzle-to-target distance estimates generated using the Griess test, or allow distance estimates when the Griess test is not feasible. Unlike what has been previously reported, testing on the original evidence (or similar substitute) is warranted when physical damage is used to estimate shooting distance. © 2017 American Academy of Forensic Sciences.

    Full Text Available Female pseudohermaphroditism represents discrepancy between karyotype and gonadal features on one side and a psychogenic phenotype on the other. Congenital adrenal hyperplasia is the part of the spectrum of female pseudohaermaofroditism and is due to an enzyme deficiency in steroidogenesis. More than 95% of patients have 21 hydroxylase deficiency which leads to a lack of cortisol and ACTH hypersecretion of pituitary, overproduction of 17 hydroxy progesterone (17OHP and androgens and adrenal cortex hyperplasia. The clinical phenotype is classified as classical and nonclassical (aka. 'Late onset' form. The classic form is represented as salt-waisting and simply virilizing, depending on the degree of lack of aldosterone. Pathophysiology of CAH due to the lack of 21α hydroxylase is closely associated with the degree of enzyme deficiency. Overproduction of androgens is leading to accelerated virilisation. Classical form is manifested in childhood and is characterized by the overproduction of cortisol precursors and adrenal androgens. In the most severe form, co-aldosterone deficiency leads to loss of salt with all the complications. Girls with the classical form of CAH typically have am ambiguous genitals at birth due to high concentrations of androgens in utero. CAH due to 21OH deficiency is the most common cause of ambiguous genitals in 46XX newborns. Characteristically, the clitoris is enlarged, partially fused labia maiora and a common urogenital sinus at the site of the urethra and vagina. The uterus, Fallopian tubes and ovaries are present and normal, a structures of Wolfian duct are absent. When diagnosed in childhood 46XX CAH patients has been assigned female gender so far, even in fully expressed in virilised external genitalia. This dogmatic approach is based on preserving fertility, and if there was at least uterus, opting for female sex was considered justified. Only about 5% of 46 patients with XX KAH has a psychogenic male gender, as

    Full Text Available As it is known from recent investigations 448 glaciers are situated on the Kamchatka Peninsula, their total area are about 905 km2 [8]. More than 80% of them are glaciers of the Sredinny Range and the Klyuchevskaya group that is explained by large altitudes of them. Glaciers of the Kronotsky Penisula are less studied since this territory is practically not influenced by present-day volcanic processes. This paper presents results of investigation of changes in glaciations of the Kronotsky Peninsula and the mountain mass Alney-Chashakondzha (Fig. 1.The following materials are used: 1 the Landsat satellite picture of September 2nd, 2013; 2 pictures from satellite WorldView-2 of July 20th, 2010, and of August 1st, 2012 with spatial resolution of about 1 m; 3 aerial photographs made in August of 1950; 4 topographic maps of the 1:100 000 scale; 5 data from the USSR Glacier Inventory; 6 results of observations at hydrometeorological stations (HMS Klyuchi and Kronoki (1950–2006 (www.meteo.ru.According to data from the USSR Glacier Inventory 32 glaciers were situated on the Kronotsky Peninsula, their total area 91.9 km2. By 2013, six glaciers disintegrated. Deciphering of the Landsat pictures did show 50 glaciers. Among them 23 glaciers are presented in the Inventory and they still hold their wholeness; 13 glaciers are segments of six disintegrated ones; 14 glaciers found in the pictures are not presented in the Inventory. Changes in areas of the Kronotsky Peninsula glaciers for period 1950–2013 in dependence on their sizes and expositions are shown in Tables 1 and 2.According to the Inventory 26 glaciers were situated in region of the Alney-Chashakondzha massif, their total area 61.4 km2. By 2010, four of them disintegrated.

    Full Text Available Los últimos 25 años del siglo XX han supuesto un sustancial cambio en el modelo de crecimiento de la población andaluza. Así, mientras la caída de la fecundidad y la estabilización de las tasas de mortalidad han contribuido a un progresivo retroceso de la vitalidad natural, la masiva emigración de antaño ha dado paso al papel de Andalucía como incipiente foco de inmigración y al creciente protagonismo de movimientos internos de relocalización de la población. Desde el punto de vista territorial estas afirmaciones quedan matizadas por los notables contrastes que se producen entre los distintos ámbitos que conforman la región y que contraponen al medio rural con el urbano, al litoral con el interior o a las grandes ciudades con sus periferias.

    2013-08-01

    Monozygotic twins, developed from a single zygote, are almost identical in clinical phenotype and concordant karyotypes. Monozygotic twins with discordant karyotypes are thought to be quite rare. Here, we report monochorionic-diamniotic twins discordant for Down syndrome. On findings of prenatal ultrasonography, nuchal translucency thickness was different between twins, and suggested that one of the twins was at high risk for having chromosomal abnormalities including Down syndrome. The twins were monochorionic-diamniotic; therefore, chorionic villi sampling of the common placenta was performed. The karyotype of the chorionic villi cells was 46,XX, and pregnancy was maintained. After delivery, dysmorphic clinical features suggesting Down syndrome were found in one of the twins, while the other twin showed a morphologically normal appearance. Karyotypes of peripheral blood leukocytes were repeatedly normal in the dysmorphic twin; however, the karyotype of skin fibroblasts from the dysmorphic twin indicated Down syndrome mosaicism; 47,XX,+21[99]/46,XX[2]. The karyotype of skin fibroblasts from the morphologically normal twin was 46,XX. Monozygosity of the twins was confirmed by a short tandem repeat analysis using 16 polymorphic markers. A mitotic nondisjunction followed by the twinning would explain the discordant karyotypes between monozygotic twins.

  10. Relaxation in the XX quantum chain

    Platini, Thierry; Karevski, Dragi

    2007-01-01

    We present the results obtained on the magnetization relaxation properties of an XX quantum chain in a transverse magnetic field. We first consider an initial thermal kink-like state where half of the chain is initially thermalized at a very high temperature T b while the remaining half, called the system, is put at a lower temperature T s . From this initial state, we derive analytically the Green function associated with the dynamical behaviour of the transverse magnetization. Depending on the strength of the magnetic field and on the temperature of the system, different regimes are obtained for the magnetic relaxation. In particular, with an initial droplet-like state, that is a cold subsystem of the finite size in contact at both ends with an infinite temperature environment, we derive analytically the behaviour of the time-dependent system magnetization

    Full Text Available The anniversary of the events that have put their mark on Romanian education and science is always an opportunity to make the balance of the successes, but also a duty to position them correctly in the national and international cultural landscape. Even more favourable is the context in which the anniversary years contain several milestones that blend organically and give the measure of quantitative and qualitative accumulations, as well as the measure of the facts of those who have put their mark on the kaleidoscope of professional and scientific successes. How can an anniversary moment be marked more durably than by publishing a book in whose pages there are elaborately gathered the trace elements of a 20-year journey in the fascinating landscape of economic science? As Professor Nicolae Istudor, PhD, the Rector of the Bucharest University of Economic Studies states at the beginning of this book entitled Amfiteatru Economic – Year XX, the 105th Anniversary of the Bucharest University of Economic Studies happily coincides with “two decades since the publishing of the first issue of the Amfiteatru Economic journal and 10 years since the latter’s indexing in Clarivate Analytics Web of Science. The Journal significantly contributes to the international and scientific visibility and recognition of ASE Bucharest”. The author thus reiterates the special place that such a publication, the fruit of an initiative started by a group of enthusiasts, and continued by the multitude of scholars who have directed the best results of their scientific efforts towards it, has in the efforts of The Bucharest University of Economic Studies to continue its path as an advanced research and education university

  18. XY females do better than the XX in the African pygmy mouse, Mus minutoides.

    2014-07-01

    All therian mammals have a similar XY/XX sex-determination system except for a dozen species. The African pygmy mouse, Mus minutoides, harbors an unconventional system in which all males are XY, and there are three types of females: the usual XX but also XX* and X*Y ones (the asterisk designates a sex-reversal mutation on the X chromosome). The long-term evolution of such a system is a paradox, because X*Y females are expected to face high reproductive costs (e.g., meiotic disruption and loss of unviable YY embryos), which should prevent invasion and maintenance of a sex-reversal mutation. Hence, mechanisms for compensating for the costs could have evolved in M. minutoides. Data gathered from our laboratory colony revealed that X*Y females do compensate and even show enhanced reproductive performance in comparison to the XX and XX*; they produce significantly more offspring due to (i) a higher probability of breeding, (ii) an earlier first litter, and (iii) a larger litter size, linked to (iv) a greater ovulation rate. These findings confirm that rare conditions are needed for an atypical sex-determination mechanism to evolve in mammals, and provide valuable insight into understanding modifications of systems with highly heteromorphic sex chromosomes. © 2014 The Author(s).

    Previous results regarding human sex chromosome aneuploidies have shown that the X and Y chromosomes affect tooth size and morphology. This study looked for the effect of sex chromosome deficiency on permanent tooth crown heights. The material, from the Finnish KVANTTI Research Project, consisted of 97 45,X females and 15 45,X/46,XX females. The controls were 32 sisters and 28 mothers of the 45,X females, eight sisters and two mothers of the 45,X/46,XX females and 35 female population controls. Crown heights of all the available teeth except third molars on both sides of the jaws were measured from panoramic radiographs with a digital calliper according to the defined procedure. The tooth crown heights were significantly smaller in the 45,X females than in the female population controls, except for the incisors and one canine in the maxilla, whereas the tooth crown heights of the 45,X/46,XX females were close to those of the normal control females. The differences between the 45,X and 45,X/46,XX females were statistically significant, excluding the upper incisor area and a few teeth in the mandible. The effect of the sex chromosome deficiency on permanent tooth crown height is due to the magnitude of lacking sex chromosome material. The present results regarding the 45,X females are parallel to previous findings in Turner patients regarding reduced mesiodistal and labiolingual dimensions and tooth crown heights in the permanent dentition.

    2012-01-01

    Translocation of the SRY gene to the paternal X chromosome is the explanation for testis development in the majority of subjects with 46,XX testicular disorder of sexual development (DSD). However, nearly all subjects with 46,XX ovotesticular DSD and up to one third of subjects with 46,XX testicular DSD lack SRY. SRY-independent expression of SOX9 has been implicated in the etiology of testis development in some individuals. We amplified microsatellite markers in the region of SOX9 from a cohort of 30 subjects with either 46,XX testicular or 46,XX ovotesticular DSD to detect SOX9 duplications. Duplication of the SOX9 region in 17q was not detected in any subject. Duplication in the region of 17q that contains SOX9 is not a common cause of testis development in subjects with SRY-negative 46,XX testicular or ovotesticular DSD.

    The human X and Y chromosomes pair and recombine at their distal short arms during male meiosis. Recent studies indicate that the majority of XX males arise as a result of an aberrant exchange between X and Y chromosomes such that the testis-determining factor gene (TDF) is transferred from a Y chromatid to an X chromatid. It has been shown that X-specific loci such as that coding for the red cell surface antigen, Xg, are sometimes lost from the X chromosome in this aberrant exchange. The ste...

  5. Long-distance entanglement and quantum teleportation in XX spin chains

    International Nuclear Information System (INIS)

    Campos Venuti, L.; Giampaolo, S. M.; Illuminati, F.; Zanardi, P.

    2007-01-01

    Isotropic XX models of one-dimensional spin-1/2 chains are investigated with the aim to elucidate the formal structure and the physical properties that allow these systems to act as channels for long-distance, high-fidelity quantum teleportation. We introduce two types of models: (i) open, dimerized XX chains, and (ii) open XX chains with small end bonds. For both models we obtain the exact expressions for the end-to-end correlations and the scaling of the energy gap with the length of the chain. We determine the end-to-end concurrence and show that model (i) supports true long-distance entanglement at zero temperature, while model (ii) supports 'quasi-long-distance' entanglement that slowly falls off with the size of the chain. Due to the different scalings of the gaps, respectively exponential for model (i) and algebraic in model (ii), we demonstrate that the latter allows for efficient qubit teleportation with high fidelity in sufficiently long chains even at moderately low temperatures

  6. Determinant representations of spin-operator matrix elements in the XX spin chain and their applications

    Science.gov (United States)

    Wu, Ning

    2018-01-01

    For the one-dimensional spin-1/2 XX model with either periodic or open boundary conditions, it is shown by using a fermionic approach that the matrix element of the spin operator Sj- (Sj-Sj'+ ) between two eigenstates with numbers of excitations n and n +1 (n and n ) can be expressed as the determinant of an appropriate (n +1 )×(n +1 ) matrix whose entries involve the coefficients of the canonical transformations diagonalizing the model. In the special case of a homogeneous periodic XX chain, the matrix element of Sj- reduces to a variant of the Cauchy determinant that can be evaluated analytically to yield a factorized expression. The obtained compact representations of these matrix elements are then applied to two physical scenarios: (i) Nonlinear optical response of molecular aggregates, for which the determinant representation of the transition dipole matrix elements between eigenstates provides a convenient way to calculate the third-order nonlinear responses for aggregates from small to large sizes compared with the optical wavelength; and (ii) real-time dynamics of an interacting Dicke model consisting of a single bosonic mode coupled to a one-dimensional XX spin bath. In this setup, full quantum calculation up to N ≤16 spins for vanishing intrabath coupling shows that the decay of the reduced bosonic occupation number approaches a finite plateau value (in the long-time limit) that depends on the ratio between the number of excitations and the total number of spins. Our results can find useful applications in various "system-bath" systems, with the system part inhomogeneously coupled to an interacting XX chain.

  7. Entanglement across extended random defects in the XX spin chain

    Science.gov (United States)

    Juhász, Róbert

    2017-08-01

    We study the half-chain entanglement entropy in the ground state of the spin-1/2 XX chain across an extended random defect, where the strength of disorder decays with the distance from the interface algebraically as Δ_l∼ l-κ . In the whole regime κ≥slant 0 , the average entanglement entropy is found to increase logarithmically with the system size L as S_L≃\\frac{c_eff(κ)}{6}\\ln L+const , where the effective central charge c_eff(κ) depends on κ. In the regime κ<1/2 , where the extended defect is a relevant perturbation, the strong-disorder renormalization group method gives c_eff(κ)=(1-2κ)\\ln2 , while, in the regime κ≥slant 1/2 , where the extended defect is irrelevant in the bulk, numerical results indicate a non-zero effective central charge, which increases with κ. The variation of c_eff(κ) is thus found to be non-monotonic and discontinuous at κ=1/2 .

  8. Inherited XX sex reversal originating from wild medaka populations.

    2010-11-01

    The teleost fish, medaka (Oryzias latipes), has an XX/XY sex-determining mechanism. A Y-linked DM domain gene, DMY, has been isolated by positional cloning as the sex-determining gene in this species. Previously, we conducted a field survey of genotypic sex and found that approximately 1% of wild medaka are sex-reversed (XX males and XY females). Here, we performed genetic analyses of nine spontaneous XX sex-reversed males to elucidate its genetic basis. In all cases, the F(1) progeny were all females, whereas XX males reappeared in the backcross (BC) progeny, suggesting that XX sex reversal is a recessive trait. Although the incidences of sex reversal in the BC progeny were mostly low, 40% were males derived from one XX male. We performed linkage analysis using 55 BC males and located a single major factor, sda-1 (sex-determining autosomal factor-1), controlling sex reversal in an autosomal linkage group. Thus, genes involved in the sex-determining pathway can be isolated from spontaneous mutants in wild populations.

    Full Text Available This article is devoted to the disclosure of changes that occurred in the French language in the XX century. The task of the authors is to present the main features characteristic of the French language of the 20th century, taking into account external history and to give their perspective assessment. World wars, the development of communication tools and the creation of new technologies, the strengthening of cultural and economic ties between France and other countries of the world had a significant impact on the evolution of the French language. Important results of the development of the French language in the period under review include: fixing a new phoneme [ŋ] in the consonantial system of the French language; enrichment of the lexical system at the expense of internal resources and at the expense of other languages; strengthening the dynamics of the development of the non-literary part of the language; increase in the number of syntactic Anglicisms. In general, the authors of the article attempted to give a detailed answer to the question: if there was the impoverishment of the French language in the twentieth century.

  10. A rare case of lateral ovotesticular disorder with Klinefelter syndrome mosaicism 46, XX/47, XXY: An unusual presentation.

    Ovotesticular disorder of sex development (OT-DSD) is a rare disorder of sexual differentiation characterized by the presence of both ovarian and testicular tissues in the same individual. It's incidence ranges from 3% to 10% of all disorder of DSD's, and the most common presentation is 46, XX followed by 46, XX/46, XY mosaicism and 46, XY. Klinefelter syndrome (KS) mosaicism 46, XX/47, XXY is extremely rare, and its association with the ovotesticular disorder is even rarer. We report an unusual case of 16-year-old with male habitus who presented with complains of cyclic hematuria. On examination, he had bilateral gynecomastia, unilateral left cryptorchidism, absent facial hair, sparse axillary hair growth, and pubic hair distribution of feminine type. The right testis was of normal size located normally in hemiscrotum and was confirmed by radio imaging. Ultrasonography and magnetic resonance imaging revealed a cystic area behind posterior half of urinary bladder. Chromosomal analysis revealed 46, XX/47, XXY mosaicism of female karyotype and KS. Histopathological report of this left side excised specimen confirmed the structures to be ovary, uterus, and fallopian tube, thus confirming our diagnosis of the lateral ovotesticular disorder. Meticulous workup combined interdisciplinary approach will lead to early diagnosis and resolve timely sex reassignment issues and also prevent consequences arising due to gonadal insufficiency.

    SOX9 is a widely expressed transcription factor playing several relevant functions during development and essential for testes differentiation. It is considered to be the direct target gene of the protein encoded by SRY and its overexpression in an XX murine gonad can lead to male development in the absence of Sry. Recently, a family was reported with a 178 kb duplication in the gene desert region ending about 500 kb upstream of SOX9 in which 46,XY duplicated persons were completely normal and fertile whereas the 46,XX ones were males who came to clinical attention because of infertility. We report a family with two azoospermic brothers, both 46,XX, SRY negative, having a 96 kb triplication 500 kb upstream of SOX9. Both subjects have been analyzed trough oligonucleotide array-CGH and the triplication was confirmed and characterised through qPCR, defining the minimal region of amplification upstream of SOX9 associated with 46,XX infertile males, SRY negative. Our results confirm that even in absence of SRY, complete male differentiation may occur, possibly driven by overexpression of SOX9 in the gonadal ridge, as a consequence of the amplification of a gene desert region. We hypothesize that this region contains gonadal specific long-range regulation elements whose alteration may impair the normal sex development. Our data show that normal XX males, with alteration in copy number or, possibly, in the critical sequence upstream to SOX9 are a new category of infertility inherited in a dominant way with expression limited to the XX background.

  14. Obtaining highly excited eigenstates of the localized XX chain via DMRG-X

    We benchmark a variant of the recently introduced density matrix renormalization group (DMRG)-X algorithm against exact results for the localized random field XX chain. We find that the eigenstates obtained via DMRG-X exhibit a highly accurate l-bit description for system sizes much bigger than the direct, many-body, exact diagonalization in the spin variables is able to access. We take advantage of the underlying free fermion description of the XX model to accurately test the strengths and limitations of this algorithm for large system sizes. We discuss the theoretical constraints on the performance of the algorithm from the entanglement properties of the eigenstates, and its actual performance at different values of disorder. A small but significant improvement to the algorithm is also presented, which helps significantly with convergence. We find that, at high entanglement, DMRG-X shows a bias towards eigenstates with low entanglement, but can be improved with increased bond dimension. This result suggests that one must be careful when applying the algorithm for interacting many-body localized spin models near a transition.

    2016-05-01

    High quality information is critical for informed decision-making in pregnancy following a prenatal diagnosis of sex chromosome aneuploidy. The goal of this study was to define the spectrum of outcomes in patients with prenatally diagnosed 45,X/46,XX mosaic Turner syndrome in order to provide a better basis for genetic counseling at the time of intrauterine diagnosis. Phenotype data for twenty-five patients with prenatally diagnosed 45,X/46,XX mosaicism were collected by retrospective chart review and, when possible, semi-structured telephone interview. Existing data from a cohort of 58 patients with postnatally diagnosed 45,X/46,XX mosaicism were used for comparison. Relative to those diagnosed postnatally, prenatal patients were more likely to have normal growth and normal secondary sexual development, less likely to manifest distinctive Turner syndrome features such as nuchal webbing and edema, and had significantly fewer renal defects. These differences underscore the need for a nuanced approach to prenatal counseling in cases of 45,X/46,XX mosaicism. © 2016 Wiley Periodicals, Inc.

FISH for X and Y chromosomes, PCR for the SRYgene and amelogenin gene in the Xp (AMGX) and (AMGY), and losses or gains with CGH. FISH analysis using X and Y chromosome-specific probes showed an X chromosome containing Y chromosome sequences on the top of the short arm; this Y chromosome region was not visible by conventional cytogenetic analysis. PCR amplification of DNA showed the presence of the sex-determining region of the Y chromosome (SRY) and the amelogenin gene in the pseudoautosomal boundary of the X chromosome (AMGX). CGH confirmed the presence of the chromosome region Yp11.2-pter and detected the presence of the two otherwise normal X chromosomes. The two Xpter (XPAR1) pseudoautosomal regions present in this XX male suggest the need to reevaluate XX males using CGH and PCR to characterize the clinical variability in XX males due to genes other than those located on the Y chromosome.

    XX female gonadal dysgenesis (XX-GD) is a rare, genetically heterogeneous disorder characterized by lack of spontaneous pubertal development, primary amenorrhea, uterine hypoplasia, and hypergonadotropic hypogonadism as a result of streak gonads. Most cases are unexplained but thought to be autosomal recessive. We elucidated the genetic basis of XX-GD in a highly consanguineous Palestinian family by using homozygosity mapping and candidate-gene and whole-exome sequencing. Affected females were homozygous for a 3 bp deletion (NM_016556.2, c.600_602del) in the PSMC3IP gene, leading to deletion of a glutamic acid residue (p.Glu201del) in the highly conserved C-terminal acidic domain. Proteasome 26S subunit, ATPase, 3-Interacting Protein (PSMC3IP)/Tat Binding Protein Interacting Protein (TBPIP) is a nuclear, tissue-specific protein with multiple functions. It is critical for meiotic recombination as indicated by the known role of its yeast ortholog, Hop2. Through the C terminus (not present in yeast), PSMC3IP also coactivates ligand-driven transcription mediated by estrogen, androgen, glucocorticoid, progesterone, and thyroid nuclear receptors. In cell lines, the p.Glu201del mutation abolished PSMC3IP activation of estrogen-driven transcription. Impaired estrogenic signaling can lead to ovarian dysgenesis both by affecting the size of the follicular pool created during fetal development and by failing to counteract follicular atresia during puberty. PSMC3IP joins previous genes known to be mutated in XX-GD, the FSH receptor, and BMP15, highlighting the importance of hormonal signaling in ovarian development and maintenance and suggesting a common pathway perturbed in isolated XX-GD. By analogy to other XX-GD genes, PSMC3IP is also a candidate gene for premature ovarian failure, and its role in folliculogenesis should be further investigated.

    A 62-yr-old man with two healthy daughters was diagnosed with osteomyelofibrosis. To our surprise, a female XX-karyotype was observed in bone marrow and confirmed in PHA-stimulated T-lymphocytes from peripheral blood. Further molecular genetic investigation revealed a submicroscopic translocation between the short arm of X and Y, which leads to an XX-male genotype based on an unbalanced translocation X;Y. This rare coincidence was further accentuated as the USP9Y gene, suspected to be to be involved in sperm cell production, was absent, but no azoospermia was present. In general, routine cytogenetics may result in findings that need to be further delineated and, as here, lead to a rare observation. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    We present a case of X-Y translocation with male phenotype (46,XX testicular disorder of sex development) and review the literature. Disorders of sex development with mismatch of genetic, gonadal and phenotypic sex are quite rare, and some are due to genetic or chromosomal abnormalities. The karyotype was investigated by a cytogenetic study of peripheral blood (phytohemagglutinin-timulated lymphocyte culture over 72 hours). G-banding analysis of 25 metaphases showed a 46,XX chromosome constitution (46 chromosomes with XX sexual composition). Fluorescence in situ hybridization (FISH) analysis with probes for X centromeres and the sex-determining region of the Y chromosome (SRY) (testis-determining factor gene) showed two X chromosomes. The analysis also showed the SRY signal in the telomeric region of the short arm of one of the chromosomes. In recent years, a number of other genes involved in disorders of sex development in animals and humans have also been identified. Genetic defects in the peptide hormone receptors, members of the steroid receptor superfamily, and other transcription factors, as well as any of a series of enzymes and cofactors involved in steroid biosynthesis can cause abnormal determination and differentiation. Although chromosomal abnormalities are rarely present in patients with apparently normal external genitalia, they should be considered in urology consultations by adolescents and adults, particularly in the investigation of gynecomastia or infertility.

  19. Universal parity effects in the entanglement entropy of XX chains with open boundary conditions

    We consider the Rényi entanglement entropies in the one-dimensional XX spin-chains with open boundary conditions in the presence of a magnetic field. In the case of a semi-infinite system and a block starting from the boundary, we derive rigorously the asymptotic behavior for large block sizes on the basis of a recent mathematical theorem for the determinant of Toeplitz plus Hankel matrices. We conjecture a generalized Fisher–Hartwig form for the corrections to the asymptotic behavior of this determinant that allows the exact characterization of the corrections to the scaling at order o(l -1 ) for any n. By combining these results with conformal field theory arguments, we derive exact expressions also in finite chains with open boundary conditions and in the case when the block is detached from the boundary

    In this paper, we study the quantum properties for a system that consists of a central atom interacting with surrounding spins through the Heisenberg XX couplings of equal strength. Employing the Heisenberg equations of motion we manage to derive an exact solution for the dynamical operators. We consider that the central atom and its surroundings are initially prepared in the excited state and in the coherent spin state, respectively. For this system, we investigate the evolution of variance squeezing and entanglement. The nonclassical effects have been remarked in the behavior of all components of the system. The atomic variance can exhibit revival-collapse phenomenon based on the value of the detuning parameter.

    Nowadays, the radioprotection activities are governed by the ALARA principle. To comply with, we have decided to use scintillators, due to their high efficiency. The surface mounted devices allow the design of the entire gross gamma ray measuring system into a volume of about 0.5 liters. The microcontrollers having an EPROM of 4k bytes offer the opportunity to run resident programmes dedicated to: data acquisition, local processing, data transmission, and system supervising. Such an intelligence is embedded into SIG XX probes. By designing an array of such probes, one can easily obtain a portal monitor, an area monitor and so on, each of them under the the control of a PC. A few modifications may transform an intelligent probe into a portable instrument for radioprotection. In such a case, to make the probe shorter, replacing the photomultiplier by a photodiode, is an attractive goal. To reach it, a dedicated charge preamplifier has to be developed. The works and results on SIG XX probes and charge preamplifier are reported. (authors)

  14. A Korean boy with 46,XX testicular disorder of sex development caused by SOX9 duplication.

    2014-06-01

    The 46,XX testicular disorder of sex development (DSD), also known as 46,XX male syndrome, is a rare form of DSD and clinical phenotype shows complete sex reversal from female to male. The sex-determining region Y (SRY) gene can be identified in most 46,XX testicular DSD patients; however, approximately 20% of patients with 46,XX testicular DSD are SRY-negative. The SRY-box 9 (SOX9) gene has several important functions during testis development and differentiation in males, and overexpression of SOX9 leads to the male development of 46,XX gonads in the absence of SRY. In addition, SOX9 duplication has been found to be a rare cause of 46,XX testicular DSD in humans. Here, we report a 4.2-year-old SRY-negative 46,XX boy with complete sex reversal caused by SOX9 duplication for the first time in Korea. He showed normal external and internal male genitalia except for small testes. Fluorescence in situ hybridization and polymerase chain reaction (PCR) analyses failed to detect the presence of SRY, and SOX9 intragenic mutation was not identified by direct sequencing analysis. Therefore, we performed real-time PCR analyses with specific primer pairs, and duplication of the SOX9 gene was revealed. Although SRY-negative 46,XX testicular DSD is a rare condition, an effort to make an accurate diagnosis is important for the provision of proper genetic counseling and for guiding patients in their long-term management.

    The 46,XX testicular disorder of sex development (46,XX testicular DSD) is a rare phenotype associated with disorder of the sex chromosomes. We describe the clinical, molecular, and cytogenetic findings of a 16- and a 30-year-old male patient with sex-determining region Y (SRY)-positive 46,XX testicular DSD. Chromosomal analysis revealed 46,XX karyotype. Fluorescence in situ hybridization (FISH) showed the SRY region translocated to the short arm of the X chromosome. The presence of the SRY gene was also confirmed by polymerase chain reaction (PCR). The X chromosome inactivation (XCI) assay showed that both patients have a random pattern of X chromosome inactivation. This report compares the symptoms and features of the SRY-positive 46,XX testicular DSD patients.

    2013-02-01

    We report on the development of high power, 9xx-10xx nm laser diode bars for use in direct diode systems and for solidstate and fibre laser pumping with applications in industrial markets. For 1 cm wide bars on micro channel cooler (MCC) we have achieved a reliable output power of 250 W across the 900 nm - 1060 nm range. At this output power level we have achieved power conversion efficiencies of 65-66 % and 90 % power content slow axis beam divergence of ~6.5°. Results of a 6400 h life test show an average power degradation of 0.6 % per 1000 h at this operating power level. We will also show results of high power bars assembled on the new OCLARO conductive cooler, the BLM. This new cooler has a small footprint of 12.6 mm × 24.8 mm and is designed for lateral or vertical stacking of diodes in multi kilowatt systems but with the benefits associated with a conductive cooler. The thermal properties are shown to be the same as for a standard CS mount. 1 cm wide high fill factor bars and 0.5 cm wide low fill factor half bars assembled on the BLM operate at 63-64 % power conversion efficiency (PCE) with output powers of up to 250 W and 150 W, respectively.

  9. FAST20XX: Achievements On European Suborbital Space Flight

    Science.gov (United States)

    Mack, A.; Steelant, J.; Adirim, H.; Lentsch, A.; Marini, M.; Pilz, N.

    2011-05-01

    In Europe, the EC co-funded project FAST20XX aims at exploring the borderline between aviation and space by investigating suborbital vehicles. The main focus is the identification and mastering of critical technologies for such vehicles rather than the vehicle development itself. Besides the objectives and overall layout of the project, the paper addresses also the progress made during the first period of the project. Two vehicle concepts are considered. A first one is a space vehicle launched from an airplane providing a low-energy ballistic flight experience using hybrid propulsion. The second is a vertically starting two-stage rocket space vehicle system concept taken as a basis to identify the conditions and constraints experienced during high- energy suborbital ultra-fast transport. The paper mainly discusses the two actual reference vehicles and the technical aspects of prerequisites for commercial operation including safety, human spaceflight, business cases, environmental and legal issues.

    Previous studies indicated that maturation inducing hormone, 17α, 20β-Dihydroxy-4-pregnen-3-one (DHP), probably through nuclear progestin receptor (Pgr), might be involved in spermatogenesis and oogenesis in fish. To further elucidate DHP actions in teleostean ovarian differentiation, we analyzed the expression of pgr in the ovary of Nile tilapia (Oreochromis niloticus), and performed RU486 (a synthetic Pgr antagonist) treatment in XX fish from 5 days after hatching (dah) to 120dah. Tilapia Pgr was abundantly expressed in the follicular cells surrounding oocytes at 30 and 90dah. Continuous RU486 treatment led to the blockage of oogenesis and masculinization of somatic cells in XX fish. Termination of RU486 treatment and maintenance in normal condition resulted in testicular differentiation, and estrogen compensation in RU486-treated XX fish successfully restored oogenesis. In RU486-treated XX fish, transcript levels of female dominant genes were significantly reduced, while male-biased genes were evidently augmented. Meanwhile, both germ cell mitotic and meiotic markers were substantially reduced. Consistently, estrogen production levels were significantly declined in RU486-treated XX fish. Taken together, our data further proved that DHP, possibly through Pgr, might be essential in the ovarian differentiation and estrogen production in fish. - Highlights: • DHP plays a critical role in early stage oogenesis of XX tilapia. • Blockage of DHP actions by RU486 treatment led to masculinization and/or sex reversal in XX tilapia. • Both DHP and estrogen are indispensable for ovarian differentiation.

    We report a case of 11-year-old girl with growth retardation and 46, XX, Xq27-qter deletion. The endocrinologic evaluation revealed growth hormone deficiency. In karyotype analysis  46, XX, Xq27-qter deletion was determined. The deletion of terminal region of chromosome 27 is most commonly being detected during the evaluation of infertility, premature ovarian insufficiency or in screening for fragile X carrier status. To our knowledge, this is the first reported case with 46, XX, Xq27-qter deletion and growth hormone deficiency. Furthermore, this case might facilitate future search for candidate genes involved in growth hormone deficiency.

    Recently Yeo showed that thermal states in Heisenberg XX model with periodic boundary condition could be used for three-party quantum teleportation. However it is hard to implement the periodic boundary condition in spin chain. So instead of imposing the periodic boundary condition, we consider open boundary condition in Heisenberg XX model and investigate the possibility of using thermal states in Heisenberg XX model with open boundary condition. Using this way, we find the best fidelity conditions to three known protocols in three-party quantum teleportation. It turns out that the best fidelity in every protocol would be 23

    The main factor influencing sex determination of an embryo is the sex-determining region Y (SRY), a master regulatory gene located on the Y chromosome. The presence of SRY causes the bipotential gonad to differentiate into a testis. However, some individuals carry a Y chromosome but are phenotypically female (46,XY females) or have a female karyotype but are phenotypically male (46,XX males). 46, XX male is rare (1:20 000 in newborn males), and SRY positivity is responsible for this condition in approximately 90% of these subjects. External genitalia of 46,XX SRY-positive males appear as normal male external genitalia, and such cases are diagnosed when they present with small testes and/or infertility after puberty. Herein, we report an adolescent who presented with low testicular volume and who was diagnosed as a 46,XX male. SRY positivity was demonstrated in the patient by fluorescence in situ hybridization method.

    To establish the prevalence of risk factors for aortic dissection, such as bicuspid aortic valve, aortic coarctation and ascending aorta dilatation, in women with low-level 45,X/46,XX mosaicism undergoing an in-vitro fertilization (IVF) procedure. The study group comprised 25 women with low-level 45,X/46,XX mosaicism (ranging from 3.3% to 10.0%) who were referred to two reproductive medicine units between 2009 and 2013 because of infertility and who underwent subsequent karyotyping. In accordance with the recommendation of the Practice Committee of the American Society for Reproductive Medicine for patients with Turner syndrome (TS), prior to the IVF procedure, all women underwent careful cardiovascular screening for congenital heart disease and thoracic aorta dilatation, including standard cardiac examination, echocardiography and non-contrast cardiac magnetic resonance imaging. Aortic size index (ASI, diameter of the ascending aorta normalized to body surface area) and the prevalence of coarctation of the aorta and of bicuspid aortic valve were compared with findings previously reported in women with TS and the general population. Bicuspid aortic valve without any stenosis or regurgitation was found in one woman in the study group with low-level 45,X/46,XX mosaicism, a statistically significantly lower prevalence of bicuspid aortic valve than that reported in women with TS. Aortic coarctation was not identified in any individual. The ASI was below the  95th percentile in all cases and the mean value was significantly lower than the mean reference values for both the general population and women with TS. Compared with the general population, the prevalence of risk factors for aortic dissection was not found to be higher in women with low-level 45,X/46,XX mosaicism without any noticeable features except infertility.

  18. XX/XY System of Sex Determination in the Geophilomorph Centipede Strigamia maritima.

    Directory of Open Access Journals (Sweden)

    Jack E Green

    Full Text Available We show that the geophilomorph centipede Strigamia maritima possesses an XX/XY system of sex chromosomes, with males being the heterogametic sex. This is, to our knowledge, the first report of sex chromosomes in any geophilomorph centipede. Using the recently assembled Strigamia genome sequence, we identified a set of scaffolds differentially represented in male and female DNA sequence. Using quantitative real-time PCR, we confirmed that three candidate X chromosome-derived scaffolds are present at approximately twice the copy number in females as in males. Furthermore, we confirmed that six candidate Y chromosome-derived scaffolds contain male-specific sequences. Finally, using this molecular information, we designed an X chromosome-specific DNA probe and performed fluorescent in situ hybridization against mitotic and meiotic chromosome spreads to identify the Strigamia XY sex-chromosome pair cytologically. We found that the X and Y chromosomes are recognizably different in size during the early pachytene stage of meiosis, and exhibit incomplete and delayed pairing.

    SRY-positive XX testicular disorder of sex development (DSD) caused by X;Y translocations was not yet reported in domestic animals. In humans it is rarely diagnosed and a majority of clinical features resemble those which are typical for Klinefelter syndrome (KS). Here we describe the first case of SRY-positive XX DSD in a tortoiseshell cat with a rudimentary penis and a lack of scrotum. Molecular analysis showed the presence of two Y-linked genes (SRY and ZFY) and a normal sequence of the SRY gene. Application of classical cytogenetic techniques revealed two X chromosomes (38,XX), but further FISH studies with the use of the whole X chromosome painting probe and BAC probes specific to the Yp chromosome facilitated identification of Xp;Yp translocation. The SRY gene was localised at a distal position of Xp. The karyotype of the studied case was described as: 38,XX.ish der(X)t(X;Y)(p22;p12)(SRY+). Moreover, the X inactivation status assessed by a sequential R-banding and FISH with the SRY-specific probe showed a random inactivation of the derivative X(SRY) chromosome. Our study showed that among DSD tortoiseshell cats, apart from XXY trisomy and XX/XY chimerism, also SRY-positive XX cases may occur. It is hypothesized that the extremely rare occurrence of this abnormality in domestic animals, when compared with humans, may be associated with a different organisation of the Yp arm in these species.

    Many autoimmune diseases are characterised by a female predominance. This may be caused by sex hormones, sex chromosomes or both. This report uses a transgenic mouse model to investigate how sex chromosome complement, not confounded by differences in gonadal type, might contribute to lupus pathogenesis. Transgenic NZM2328 mice were created by deletion of the Sry gene from the Y chromosome, thereby separating genetic from gonadal sex. Survival, renal histopathology and markers of immune activation were compared in mice carrying the XX versus the XY(-) sex chromosome complement, with each genotype being ovary bearing. Mice with XX sex chromosome complement compared with XY(-) exhibited poorer survival rates and increased kidney pathology. Splenic T lymphocytes from XX mice demonstrated upregulated X-linked CD40 ligand expression and higher levels of activation markers ex vivo. Increased MMP, TGF and IL-13 production was found, while IL-2 was lower in XX mice. An accumulation of splenic follicular B cells and peritoneal marginal zone B cells was observed, coupled with upregulated costimulatory marker expression on B cells in XX mice. These data show that the XX sex chromosome complement, compared with XY(-), is associated with accelerated spontaneous lupus.

    Gapless phases in ground states of low-dimensional quantum spin systems are rather ubiquitous. Their peculiarity is a remarkable sensitivity to external perturbations due to permanent criticality of such phases manifested by a slow (power-low) decay of pair correlations and the divergence of the corresponding susceptibility. A strong influence of various defects on the properties of the system in such a phase can then be expected. Here, we consider the influence of vacancies on the thermodynamics of the simplest quantum model with a gapless phase, the isotropic spin-1/2 XX chain. The existence of the exact solution of this model gives a unique opportunity to describe in detail the dramatic effect of dilution on the gapless phase—the appearance of an infinite series of quantum phase transitions resulting from level crossing under the variation of a longitudinal magnetic field. We calculate the jumps in the field dependences of the ground-state longitudinal magnetization, susceptibility, entropy, and specific heat appearing at these transitions and show that they result in a highly nonlinear temperature dependence of these parameters at low T. Also, the effect of enhancement of the magnetization and longitudinal correlations in the dilute chain is established. The changes of the pair spin correlators under dilution are also analyzed. The universality of the mechanism of the quantum transition generation suggests that similar effects of dilution can also be expected in gapless phases of other low-dimensional quantum spin systems.

    Full Text Available This publication presents the results of investigations, which had began in 1980 at the Rudi XX settlement in the Soroca District of the Republic of Moldova, obtained in 1982. There was confirmed the multi-layered structure of the site and the horizon of the Iron Age was first identified. But because of the small number and inexpressiveness of the ceramic findings, this layer was previously dated by a rather long period of time – from the late Hallstatt (7th-6th centuries BC to the Getic culture (4th-3rd centuries BC. The discovered structure in the form of a heavily burned pit was attributed, as a hypothesis, to the Getic crematorium. The production character of the early medieval settlement has been confirmed (presence of iron slag, fragments of ceramic blowing nozzles and iron ore. The remains of three ovens of the 8th-9th centuries were investigated. The collection of medieval pottery of the 6th-11th centuries and individual findings of iron, stone and bone objects was assembled.

    Differentiation of the bipotential gonad into testis is initiated by the Y chromosome-linked gene SRY (Sex-determining Region Y) through upregulation of its autosomal direct target gene SOX9 (Sry-related HMG box-containing gene 9). Sequence and chromosome homology studies have shown that SRY most probably evolved from SOX3, which in humans is located at Xq27.1. Mutations causing SOX3 loss-of-function do not affect the sex determination in mice or humans. However, transgenic mouse studies have shown that ectopic expression of Sox3 in the bipotential gonad results in upregulation of Sox9, resulting in testicular induction and XX male sex reversal. However, the mechanism by which these rearrangements cause sex reversal and the frequency with which they are associated with disorders of sex development remains unclear. Rearrangements of the SOX3 locus were identified recently in three cases of human XX male sex reversal. We report on a case of XX male sex reversal associated with a novel de novo duplication of the SOX3 gene. These data provide additional evidence that SOX3 gain-of-function in the XX bipotential gonad causes XX male sex reversal and further support the hypothesis that SOX3 is the evolutionary antecedent of SRY.

    We have previously reported a dominant mouse mutant, Odd sex (Ods), in which XX Ods/+ mice on the FVB/N background show complete sex reversal, associated with expression of Sox9 in the fetal gonads. Remarkably, when crossed to the A/J strain approximately 95% of the (AXFVB) F(1) XX Ods/+ mice developed as fully fertile, phenotypic females, the remainder developing as males or hermaphrodites. Using a (AXFVB) F(2) population, we conducted a genome-wide linkage scan to identify the number and chromosomal location of potential Ods modifier genes. A single major locus termed Odsm1 was mapped to chromosome 18, tightly linked to D18Mit189 and D18Mit210. Segregation at this locus could account for the presence of sex reversal in 100% of XX Ods/+ mice which develop as males, for the absence of sex reversal in approximately 92% of XX Ods/+ mice which develop as females, and for the mixed sexual phenotype in approximately 72% of XX Ods/+ mice that develop with ambiguous genitalia. We propose that homozygosity for the FVB-derived allele strongly favors Ods sex reversal, whereas homozygosity for the A/J-derived allele inhibits it. In mice heterozygous at Odsm1, the phenotypic outcome, male, female or hermaphrodite, is determined by a complex interaction of several minor modifying loci. The close proximity of Smad2, Smad7 and Smad4 to D18Mit189/210 provides a potential mechanism through which Odsm1 might act.

    Full Text Available In the present article regulations adopted in the Russian Empire at the beginning of the XX century and defining direction of social legislation development are considered. Norms that regulated state contempt of the lower ranks and members of their families in Russia, and also laws on social insurance are considered. There was no complete system of state social contempt in the Russian Empire. Help to needed was usually provided by numerous non-state charitable structures and societies, thus many of them were under patronage of the imperial family members. This help was provided, first - selectively, second - its size usually was very small. In general, specifics of the legislative ensuring of social support were defined by the features of development of entire legal system of the Russian Empire during this period, including, dynamics of normative legal acts adoption. Author draws a conclusion about preservation of the class character in the organization of the state contempt in the Russian Empire. In 1912 in the Russian Empire acts that directed creation of the system of social insurance for social protection of persons, victims of injuries and mutilations at the factory enterprises, and members of their family’s were adopted. Adoption of the acts regulating social insurance can be considered as a positive step in development of the social orientated legislation. But these acts were far from perfect, and first of all because their action extended on smaller part of the country's working population. According to the author, adoption of the legislation on social insurance became a basic step on the way of modern forms of the organization of the social help creation.

    Ovotesticular disorder of sex development (OT-DSD) is a rare disorder of sexual differentiation characterized by the presence of both testicular and ovarian tissue in an individual and the majority of cases have been reported with 46,XX karyotype. In 46,XX cases, testicular differentiation may occur due to the translocation of SRY to the X chromosome or to an autosome. Herein, we present a female newborn with a combination of trisomy 13 and SRY (-) XX OT-DSD. Trisomy 13 is a relatively common and well-known chromosomal disorder in which disorders of sexual differentiation are not frequent. In the absence of SRY, overexpression of pro-testis genes, or decreased expression of pro-ovarian/anti-testis genes have been suggested as underlying mechanisms of testicular formation. The findings in this patient were suggestive of an underlying genomic disorder associated with FGF9 and/or SPRY2.

  10. One-Way Deficit and Quantum Phase Transitions in XX Model

    2018-02-01

    Quantum correlations including entanglement and quantum discord have drawn much attention in characterizing quantum phase transitions. Quantum deficit originates in questions regarding work extraction from quantum systems coupled to a heat bath (Oppenheim et al. Phys. Rev. Lett. 89, 180402, 2002). It links quantum thermodynamics with quantum correlations and provides a new standpoint for understanding quantum non-locality. In this paper, we evaluate the one-way deficit of two adjacent spins in the bulk for the XX model. In the thermodynamic limit, the XX model undergoes a first order transition from fully polarized to a critical phase with quasi-long-range order with decrease of quantum parameter. We find that the one-way deficit becomes nonzero after the critical point. Therefore, the one-way deficit characterizes the quantum phase transition in the XX model.

    46,XX gonadal dysgenesis is a rare genetically heterogeneous disorder characterized by underdeveloped ovaries with consequent, impuberism, primary amenorrhea, and hypergonadotropic hypogonadism. Mullerian agenesis or Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by congenital aplasia of the uterus and the upper part (2/3) of the vagina in a woman with normal development of secondary sexual characteristics and a normal 46,XX karyotype. The phenotypic manifestations of MRKH syndrome may sometimes overlap with various other syndromes and require accurate delineation. The coexistence of both these disorders is extremely rare. Here, we report a case of 46,XX gonadal dysgenesis and MRKH syndrome with anatomically dispersed congenital anomalies unique among reported cases.

    The molecular mechanisms underlying sex differences in dyslipidemia are poorly understood. We aimed to distinguish genetic and hormonal regulators of sex differences in plasma lipid levels. We assessed the role of gonadal hormones and sex chromosome complement on lipid levels using the four core genotypes mouse model (XX females, XX males, XY females, and XY males). In gonadally intact mice fed a chow diet, lipid levels were influenced by both male-female gonadal sex and XX-XY chromosome complement. Gonadectomy of adult mice revealed that the male-female differences are dependent on acute effects of gonadal hormones. In both intact and gonadectomized animals, XX mice had higher HDL cholesterol (HDL-C) levels than XY mice, regardless of male-female sex. Feeding a cholesterol-enriched diet produced distinct patterns of sex differences in lipid levels compared with a chow diet, revealing the interaction of gonadal and chromosomal sex with diet. Notably, under all dietary and gonadal conditions, HDL-C levels were higher in mice with 2 X chromosomes compared with mice with an X and Y chromosome. By generating mice with XX, XY, and XXY chromosome complements, we determined that the presence of 2 X chromosomes, and not the absence of the Y chromosome, influences HDL-C concentration. We demonstrate that having 2 X chromosomes versus an X and Y chromosome complement drives sex differences in HDL-C. It is conceivable that increased expression of genes escaping X-inactivation in XX mice regulates downstream processes to establish sexual dimorphism in plasma lipid levels. © 2015 American Heart Association, Inc.

    Salmonids are generally considered to have a robust genetic sex determination system with a simple male heterogamety (XX/XY). However, spontaneous masculinization of XX females has been found in a rainbow trout population of gynogenetic doubled haploid individuals. The analysis of this masculinization phenotype transmission supported the hypothesis of the involvement of a recessive mutation (termed mal). As temperature effect on sex differentiation has been reported in some salmonid species, in this study we investigated in detail the potential implication of temperature on masculinization in this XX mal-carrying population. Seven families issued from XX mal-carrying parents were exposed from the time of hatching to different rearing water temperatures ((8, 12 and 18°C), and the resulting sex-ratios were confirmed by histological analysis of both gonads. Our results demonstrate that masculinization rates are strongly increased (up to nearly two fold) at the highest temperature treatment (18°C). Interestingly, we also found clear differences between temperatures on the masculinization of the left versus the right gonads with the right gonad consistently more often masculinized than the left one at lower temperatures (8 and 12°C). However, the masculinization rate is also strongly dependent on the genetic background of the XX mal-carrying families. Thus, masculinization in XX mal-carrying rainbow trout is potentially triggered by an interaction between the temperature treatment and a complex genetic background potentially involving some part of the genetic sex differentiation regulatory cascade along with some minor sex-influencing loci. These results indicate that despite its rather strict genetic sex determinism system, rainbow trout sex differentiation can be modulated by temperature, as described in many other fish species.

    Patients with Congenital Adrenal Hyperplasia (CAH) owing to 21-hydroxylase deficiency and whose karyotype is 46, XX are usually assigned to the female gender. Reported herein are the long term outcomes in three patients with CAH whose karyotype is 46, XX and who were reared as males. A retrospective review of three CAH patients with a 46, XX karyotype who were reared as males was conducted. Gender assignment, clinical and biochemical data, pre and post-genitoplasty genital examinations were reviewed. Gender identity was tested by an extensive questionnaire. Gender role, sexual preference, marital status and sexual satisfaction were evaluated by interview. The three patients were genotyped for the CYP21A2 gene confirming the diagnosis of CAH. Owing to genital virilization, cultural preferences for male gender and the lack of newborn screening programs the three patients reported herein were assigned to the male gender at birth before the diagnosis of CAH was established. In adulthood the patients remained significantly virilized. Thorough psychosexual assessments in adulthood revealed well established male gender identities compatible with their male gender assignments at birth. In all three patients, gender role and behavior were consistent with male gender identity including sexual intercourse with female partners. The three patients reported herein revealed that male gender assignment to CAH patients with a 46, XX karyotype may have a successful outcome providing there is strong parental support and expert endocrine care. No standard guidelines have been published for the gender assignment of CAH patients with a 46, XX karyotype and genital ambiguity. More studies concerning gender assignment in CAH patients with a 46, XX karyotype reared as males are needed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The present case report describes a 6-year old subfertile pony mare, which became pregnant after the eleventh artificial insemination. The examination of the ovaries and the uterus did not reveal any abnormal clinical findings and the mare showed a regular oestrous cycle. Based on cytogenetic and molecular genetic analyses it became possible to elucidate the observed subfertility. The mosaic karyotype of the mare consisted of 63,X (20%) and 64,XX (80%) cells. A PCR analysis failed to amplify sequences from the equine SRY gene. The observed classic 63,X/64,XX mosaicism is a plausible explanation for the subfertility of the mare.

    All-female lines of fish are created by crossing sex reversed (XX genotype) males with normal females. All-female lines avoid the deleterious phenotypic effects that are typical of precocious maturation in males. To determine whether all-female and mixed sex populations of rainbow trout (Oncorhynchus mykiss) differ in performance, we compared the growth and gene expression profiles in progeny groups produced by crossing a XX male and a XY male to the same five females. Body weight and length were measured in the resulting all-female (XX) and mixed sex (XX/XY) offspring groups. Microarray experiments with liver and white muscle were used to determine if the gene expression profiles of large and small XX offspring differ from those in large and small XX/XY offspring. We detected no significant differences in body length and weight between offspring groups but XX offspring were significantly less variable in the value of these traits. A large number of upregulated genes were shared between the large XX and large XX/XY offspring; the small XX and small XX/XY offspring also shared similar expression profiles. No GO category differences were seen in the liver or between the large XX and large XX/XY offspring in the muscle. The greatest differences between the small XX and small XX/XY offspring were in the genes assigned to the "small molecule metabolic process" and "cellular metabolic process" GO level 3 categories. Similarly, genes within these categories as well as the category "macromolecule metabolic process" were more highly expressed in small compared to large XX fish.

    One of the factors which influence the spatial resolution of a 2D detector array is the size of the single detector, another the transport of the secondary electrons from the walls into the measuring volume. In this study, the single ion chamber dose response function of an I'mRT MatriXX array was determined by comparison between slit beam dose profiles measured with the array and with EBT2 radiochromic film in a solid water-equivalent phantom at a shallow depth of 0.5 cm and at a depth of 5 cm beyond the depth dose maximum for a 6 MV photon beam. The dose response functions were obtained using two methods, the best fit method and the deconvolution method. At the shallow depth, a Lorentz function and at 5 cm depth a Gaussian function, both with the same FWHM of 7.4 mm within limits of uncertainty, were identified as the best suited dose response functions of the 4.5 mm diameter single array chamber. These dose response functions were then tested on various dose profiles whose true shape had been determined with EBT2 film and with the IC03 ionization chamber. By convolving these with the Lorentz kernel (at shallow depth) and the Gaussian kernel (at 5 cm depth) the signal profiles measured with the I'mRT MatriXX array were closely approximated. Thus, the convolution of TPS-calculated dose profiles with these dose response functions can minimize the differences between calculation and measurement which occur due to the limited spatial resolution of the I'mRT MatriXX detector.

    Highlights: • Pressure drop of NACA 0020 airfoil fin PCHE reduces strikingly in comparison with the zigzag PCHE. • Pressure drop of NACA 00XX airfoil fin PCHE decreases as airfoil thickness increases. • Heat transfer performance of NACA 00XX airfoil fin PCHE increases as airfoil thickness rises. • Comprehensive performance of NACA 00XX airfoil fin PCHE degrades as airfoil thickness increases. - Abstract: Printed circuit heat exchanger (PCHE) can be used in supercritical carbon dioxide (S-CO{sub 2}) Brayton cycle. The present study compares NACA 0020 airfoil fin PCHE with conventional zigzag PCHE by numerical analysis. Pressure drop of the former has a striking reduction while maintaining excellent heat transfer performance. Comparison on four NACA 00XX series airfoil fin PCHEs is performed to investigate the influence of airfoil profile on flow and heat transfer performance. With a fixed vertical pitch, heat transfer performance of NACA series airfoil fin PCHE increases as airfoil thickness increases. However, comprehensive performance, in which both flow and heat transfer are taken into account, degrades with increasing airfoil thickness. Among four NACA airfoil fin PCHEs presented in this paper, NACA 0010 airfoil fin PCHE demonstrates the best comprehensive performance.

    Ovarian development and maintenance are poorly understood; however, diseases that affect these processes can offer insights into the underlying mechanisms. XX female gonadal dysgenesis (XX-GD) is a rare, genetically heterogeneous disorder that is characterized by underdeveloped, dysfunctional ovaries, with subsequent lack of spontaneous pubertal development, primary amenorrhea, uterine hypoplasia, and hypergonadotropic hypogonadism. Here, we report an extended consanguineous family of Palestinian origin, in which 4 females exhibited XX-GD. Using homozygosity mapping and whole-exome sequencing, we identified a recessive missense mutation in nucleoporin-107 (NUP107, c.1339G>A, p.D447N). This mutation segregated with the XX-GD phenotype and was not present in available databases or in 150 healthy ethnically matched controls. NUP107 is a component of the nuclear pore complex, and the NUP107-associated protein SEH1 is required for oogenesis in Drosophila. In Drosophila, Nup107 knockdown in somatic gonadal cells resulted in female sterility, whereas males were fully fertile. Transgenic rescue of Drosophila females bearing the Nup107D364N mutation, which corresponds to the human NUP107 (p.D447N), resulted in almost complete sterility, with a marked reduction in progeny, morphologically aberrant eggshells, and disintegrating egg chambers, indicating defective oogenesis. These results indicate a pivotal role for NUP107 in ovarian development and suggest that nucleoporin defects may play a role in milder and more common conditions such as premature ovarian failure.

    Full Text Available Forty-six XX disorder of sex development is an uncommon medical condition observed at times during the evaluation of a man′s fertility. The following is a case series and literature review of phenotypically normal men diagnosed with this karyotype. Our goal is to comprehend the patients′ clinical presentation as well as their laboratory results aiming to explore options available for their management. A formal literature review through PubMed and MEDLINE databases was performed using "46 XX man" as a word search. A total of 55 patients, including those conveyed in this article were diagnosed with a 46 XX karyotype during their fertility evaluation. The patients′ mean age ± s.d. was 34 ± 10 years and their mean height ± s.d. was 166 ± 6.5 cm. Overall, they presented with hypergonadotropic hypogonadism. Sexual dysfunction, reduced hair distribution, and gynecomastia were reported in 20% (4/20, 25.8% (8/31, and 42% (13/31 of the patients, respectively. The SRY gene was detected in 36 (83.7% and was absent in the remaining seven (16.3% patients. We found that a multidisciplinary approach to management is preferred in 46 XX patients. Screening for remnants of the mullerian ducts and for malignant transformation in dysgenetic gonads is imperative. Hypogonadism should be addressed, while fertility options are in vitro fertilization with donor sperm or adoption.

    The aim of our study was to determine the etiologic distribution of 46,XX disorder of sexual development (DSD) according to the new DSD classification system and to evaluate the clinical features of this DSD subgroup in our patient cohort. The evaluation criteria and clinical findings of 95 46,XX patients were described by clinical presentation, gonadal morphology, genital anatomy, associated dysmorphic features, presence during prenatal period with/without postnatal virilization, hormonal characteristics, and presence or absence of steroidogenic defects among 319 patients with DSD. Types and ratios of each presentation of our 95 patients with 46,XX DSD were as follows: 82 had androgen excess (86.3%): (74 had classical congenital adrenal hyperplasia, 2 had CAH variant possibility of P450-oxidoreductase gene defect), 6 had disorders of ovarian development (6.3%): (1 patient had gonadal dysgenesis with virilization at birth with bilateral streak gonad, 4 patients had complete gonadal dysgenesis, and 1 patient had ovotesticular DSD) and 7 had other 46,XX DSD. Two sisters, who had 46,XX complete gonadal dysgenesis,were diagnosed with Perrault Syndrome with ovarian failure due to streak gonads and associated with sensorineural deafness. 46,XX DSD are usually derived from intrauterine virilization and CAH is the most common cause of 46,XX DSD due to fetal androgen exposure.

    A 2-year-old boy was found to have a 47,XXX karyotype. Restriction-fragment-length-polymorphism analysis showed that, of his three X chromosomes, one is of paternal and two are of maternal origin. The results of Y-DNA hybridization were reminiscent of those in XX males in two respects. First, hybridization to Southern transfers revealed the presence in this XXX male of sequences derived from the Y-chromosomal short arm. Second, in situ hybridization showed that this Y DNA was located on the tip of the X-chromosomal short arm. We conclude that this XXX male resulted from the coincidence of X-X nondisjunction during maternal meiosis and aberrant X-Y interchange either during or prior to paternal meiosis.

    An 18-month-old, neutered male beagle presented with acute abdominal signs and a suppurative infection of the urogenital tract. Chromosomal sex was female (78, XX), gonadal sex was male (testicles), and phenotypic sex was ambiguous, with evidence of both male and female duct systems. The internal and external genitalia consisted of epididymides, an underdeveloped uterus with an immature spermatic cord, communication between the uterus or cranial vagina and the membranous urethra, a urethrographically male urethra, a hypoplastic os penis, and a hypoplastic penis with hypospadia. Based on these findings and the familial history of a similarly affected litter mate, the dog was diagnosed as having the XX male syndrome with pyovagina and uterine stump pyometra. Radiographic and ultrasonographic investigations are described, and abnormalities of chromosomal sex, gonadal sex, and phenotypic sex are discussed

    To examine the rate of maternal contamination in miscarriage specimens. Retrospective review of 1,222 miscarriage specimens submitted for chromosome testing with detection of maternal cell contamination (MCC). Referral centers requesting genetic testing of miscarriage specimens at a single reference laboratory. Women with pregnancy loss who desire complete chromosome analysis of the pregnancy tissue. Analysis of miscarriage specimens using single-nucleotide polymorphism (SNP) microarray technology with bioinformatics program to detect maternal cell contamination. Chromosome content of miscarriages and incidence of 46,XX results due to MCC. Of the 1,222 samples analyzed, 592 had numeric chromosomal abnormalities, and 630 were normal 46,XX or 46,XY (456 and 187, respectively). In 269 of the 46,XX specimens, MCC with no embryonic component was found. With the exclusion of maternal 46,XX results, the chromosomal abnormality rate increased from 48% to 62%, and the ratio for XX to XY results dropped from 2.6 to 1.0. Over half of the normal 46,XX results in miscarriage specimens were due to MCC. The use of SNPs in MCC testing allows for precise identification of chromosomal abnormalities in miscarriage as well as MCC, improving the accuracy of products of conception testing.

    Sexual development in mammals is based on a complicated and delicate network of genes and hormones that have to collaborate in a precise manner. The dark side of this pathway is represented by pathological conditions, wherein sexual development does not occur properly either in the XX and the XY background. Among them a conundrum is represented by the XX individuals with at least a partial testis differentiation even in absence of SRY. This particular condition is present in various mammals including the dog. Seven dogs characterized by XX karyotype, absence of SRY gene, and testicular tissue development were analysed by Array-CGH. In two cases the array-CGH analysis detected an interstitial heterozygous duplication of chromosome 9. The duplication contained the SOX9 coding region. In this work we provide for the first time a causative mutation for the XXSR condition in the dog. Moreover this report supports the idea that the dog represents a good animal model for the study of XXSR condition caused by abnormalities in the SOX9 locus.

    Ovotesticular disorder of sexual development (DSD) is characterized by the presence of both ovarian and testicular tissues in the same individual. The most common karyotype is 46,XX. Here, we report the case of a boy with a 46,XX/47,XXY karyotype diagnosed as ovotesticular DSD by gonadal biopsy. A 5-month-old boy presented with hypospadias, unilateral cryptorchidism, and a micropenis. Pelvic magnetic resonance imaging revealed a suspicious gonad tissue that is solid in structure in the right scrotum and a suspicious gonad that is cystic in structure in the left inguinal canal. He underwent a diagnostic laparoscopy. Cytogenetic analysis of peripheral blood revealed a 46,XX/47,XXY karyotype. Histopathologic examination of the left gonad showed ovarian tissue containing primordial follicles with ipsilateral undifferentiated tuba uterina. The right gonad showed immature testis tissue. He underwent left gonadectomy and hypospadias repair, and was raised as a male. Through this rare case, we highlight the importance of histological and cytogenetic investigation in DSD.

    47 XXY/46 XX mosaicism with characteristics suggesting Klinefelter syndrome is very rare and at present, only seven cases have been reported in the literature. We report an Indian boy diagnosed as variant of Klinefelter syndrome with 47 XXY/46 XX mosaicism at age 12 years. He was noted to have right cryptorchidism and chordae at birth, but did not have surgery for these until age 3 years. During surgery, the right gonad was atrophic and removed. Histology revealed atrophic ovarian tissue. Pelvic ultrasound showed no Mullerian structures. There was however no clinical follow up and he was raised as a boy. At 12 years old he was re-evaluated because of parental concern about his 'female' body habitus. He was slightly overweight, had eunuchoid body habitus with mild gynaecomastia. The right scrotal sac was empty and a 2mls testis was present in the left scrotum. Penile length was 5.2 cm and width 2.0 cm. There was absent pubic or axillary hair. Pronation and supination of his upper limbs were reduced and x-ray of both elbow joints revealed bilateral radioulnar synostosis. The baseline laboratory data were LH XX[67] with SRY positive. Laparoscopic examination revealed no Mullerian structures. Insisting on an adequate number of cells (at least 50) to be examined during karyotyping is important so as not to miss diagnosing mosaicism.

    We present a case of an infertile male with 46,XX/46,XYchimerism fathering a child after ICSI procedure. Conventional cytogenetic analysis on chromosomes, derived from lymphocytes, using standard Q-banding procedures with a 450-550-band resolution and short-tandem-repeat analysis of 14 loci. Analysis of 20 metaphases from lymphocytes indicated that the proband was a karyotypic mosaic with an almost equal distribution between male and female cell lines. In total, 12 of 20 (60%) metaphases exhibited a normal female karyotype 46,XX, while 8 of 20 (40%) metaphases demonstrated a normal male karyotype 46,XY. No structural chromosomal abnormalities were present. Out of 14 STR loci, two loci (D18S51 and D21S11) showed four different alleles in peripheral blood, buccal mucosal cells, conjunctival mucosal cells, and seminal fluid. In three loci (D2S1338, D7S820, and vWA), three alleles were detected with quantitative differences that indicated presence of four alleles. In DNA extracted from washed semen, four alleles were detected in one locus, and three alleles were detected in three loci. This pattern is consistent with tetragametic chimerism. There were no quantitative significant differences in peak heights between maternal and paternal alleles. STR-analysis on DNA from the son confirmed paternity. We report a unique case with 46,XX/46,XY chimerism confirmed to be tetragametic, demonstrated in several tissues, with male phenotype and no genital ambiguity with oligospermia fathering a healthy child after IVF with ICSI procedure.

    Sex in mammals is genetically determined and is defined at the cellular level by sex chromosome complement (XY males and XX females). The Y chromosome-linked gene sex-determining region Y (SRY) is believed to be the master initiator of male sex determination in almost all eutherian and metatherian mammals, functioning to upregulate expression of its direct target gene Sry-related HMG box-containing gene 9 (SOX9). Data suggest that SRY evolved from SOX3, although there is no direct functional evidence to support this hypothesis. Indeed, loss-of-function mutations in SOX3 do not affect sex determination in mice or humans. To further investigate Sox3 function in vivo, we generated transgenic mice overexpressing Sox3. Here, we report that in one of these transgenic lines, Sox3 was ectopically expressed in the bipotential gonad and that this led to frequent complete XX male sex reversal. Further analysis indicated that Sox3 induced testis differentiation in this particular line of mice by upregulating expression of Sox9 via a similar mechanism to Sry. Importantly, we also identified genomic rearrangements within the SOX3 regulatory region in three patients with XX male sex reversal. Together, these data suggest that SOX3 and SRY are functionally interchangeable in sex determination and support the notion that SRY evolved from SOX3 via a regulatory mutation that led to its de novo expression in the early gonad.

    Full Text Available Triploidy is common in human pregnancies. It is detected in 1 to 2% of clinically recognized pregnancies and in approximately 15 to 20% of spontaneous abortions produced by chromosome anomalies. We report a premature liveborn girl (30 weeks of gestation with microcephaly, facial dysmorphism and skeletal abnormalities who died at one day of age due to respiratory failure. The placenta showed partial hydatiform mole. Autopsy revealed no internal malformations. Cytogenetic analysis of 100 metaphases obtained from renal tissue culture revealed a 68,XX[73]/69,XXX[27] karyotype. To our knowledge this is the first report in the literature of 68,XX[73]/69,XXX[27] mosaicism in a liveborn infant.A triploidia é uma anomalia cromossômica comum encontrada em 1 a 2% das gestações clinicamente reconhecidas e em cerca de 15 a 20% dos abortos espontâneos de causa cromossômica. Em aproximadamente 5% dos casos, uma aneuploidia pode estar também associada (Boué et al., 1985. Descrevemos um recém-nascido do sexo feminino, prematuro (30 semanas de idade gestacional, com microcefalia, dismorfias faciais e alterações de membros, que foi a óbito com 1 dia de vida por insuficiência respiratória. O exame anátomo-patológico da placenta revelou alterações compatíveis com degeneração molar. A necrópsia da criança não evidenciou malformações internas. A análise citogenética de 100 metáfases, obtidas a partir de cultura de tecido renal, evidenciou cariótipo 68,XX[73]/69,XXX[27]. Apenas 9 casos de triploidia 68,XX foram descritos anteriormente, sendo 7 em abortos, 1 em feto de 21 semanas e 1 em recém-nascido a termo. Consideramos que este estudo seja o primeiro da literatura relatando a ocorrência de mosaicismo 69,XXX/68,XX em um recém-nascido vivo. Os autores discutem os achados clínicos e os possíveis mecanismos envolvidos nesta aberração cromossômica.

    Full Text Available En este trabajo se logró conocer los criterios de clasificación empleados para definir a la población con discapacidad en los registros censales del siglo XX en Costa Rica y, por consiguiente, una aproximación a las formulaciones conceptuales para referirse al grupo en estudio. Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX. En el procedimiento con los datos, se llevó a cabo un análisis descriptivo de distribución de frecuencias.

    Full Text Available The article includes analysis of the main reasons for activization of separatism movements in Xinjiang later in XX and earlier in XXI centuries. The author comes into conclusion that the following reasons caused the process of active politicization of ethnicity in Central Asian region and wide territories of Xinjiang: changes in the territory of former Soviet Union countries; economic recession in former Soviet Union countries which led to activization of radical movements; economic reforms in China leading to liberalization of social and political spheres; influence of external global factors. The mentioned changes resulted in serious activization of separatist tendencies which was not the case in earlier periods.

    2014-03-01

    Full Text Available The article considers the question of forms of wages paid to workers in the mining industry of Siberia in the late XIX – early XX centuries. Of the two main forms of labor compensation – hourly rate and piecework pay, the latter was more corresponding to the spirit of capitalism, and it was most widespread in the mining enterprises of Siberia. The piecework pay was also the main instrument for intensifying labor productivity. This episode in the history of labor is studied on the basis of paperwork materials of mining companies and reporting documents of the mining inspectorate.

    In this paper, it is re-examined the formulation of the quantum equivalence principle (QEP) and its compatibility with the conditions which must be fulfilled by the kernel G 1 (x,x') is discussed. It is also determined the base of solutions which give the particle model in a curved space-time in terms of Cauchy's data for such a kernel. Finally, it is analyzed the creation of particles in this model by studying the time evolution of creation and annihilation operators. This method is an alternative to one that uses Bogoliubov's transformation as a mechanism of creation. (author)

    We investigate the well-defined measures of measurement-induced nonlocality (MIN) for thermal states of the transverse field XX model, with the addition of three-spin interaction terms being introduced. The results showed that the MINs are very sensitive to system parameters of the chain. The three-spin interactions can serve as flexible parameters for enhancing MINs of the boundary spins, and the maximum enhancement achievable by varying strengths of the three-spin interactions are different for the chain with different number of spins.

    We investigate the quantum critical behavior in the XX spin chain with a XZY-YZX type multiple interaction by means of quantum correlation (Concurrence C, quantum discord D{sub Q} and geometric discord D{sub G}). Around the critical point, the values of these quantum correlations and corresponding derivatives are investigated numerically and analytically. The results show that the non-analyticity property of the concurrence cannot signal well the quantum phase transition, but both the quantum discord and geometric discord can characterize the critical behavior in such model exactly.

    Disorders of sex development (DSD) create medical and social dilemma. Maleness with XX genotype is a rare genetic condition affecting one in 24,000 new-born males. The XX male syndrome is a varied condition characterized by a spectrum of clinical presentation. ranging from normal male genitalia to ambiguous sex. Chromosomal anomalies are important cause of lack of development in secondary sexual characteristics, delayed puberty, miscarriage, infertility and other associated problems. An individual having ambiguous sex may have lifelong impact on social, psychological and sexual functions.

    Individuals with a 46,XX/46,XY karyotype are categorized as ovotesticular disorder of sexual development (ODSD) and have gonads with either an ovary on one side and a testis on the other side or a mixed ovotestis. To examine the distribution of 46,XX and 46,XY cells in gonads of 3 patients with ODSD, FISH for X and Y chromosomes and immunohistochemistry for SOX9 and FOXL2 were carried out. FISH analysis showed that XX signals were present in Sertoli cells in the seminiferous tubules, while cells containing Y signals were seen in epithelia of ovarian follicles. The immunolabeling of SOX9 and FOXL2 in the seminiferous tubules and ovarian follicles was mutually exclusive, irrespective of the presence of reversed sex chromosomes. We therefore suggest that the fate of individual gonadal epithelial cells is determined not only by the sex chromosomes but also by local environmental factors. © 2016 S. Karger AG, Basel.

    Several studies have shown an increased frequency of chromosomal aberrations in female partners of couples examined prior to intracytoplasmic sperm injection (ICSI). A retrospective cohort study was performed to determine whether 45,X/46,XX mosaicism affects the outcomes of in vitro fertilization (IVF) or ICSI. Forty-six women with a 45,X/46,XX karyotype with 6-28% of aneuploidy were compared with 59 control women (46,XX), matched for age, from the female population who underwent IVF or ICSI between 1 January 1996 and 31 December 2006 at the Reproductive Medicine Unit at Brest University Hospital. The outcomes of 254 treatment cycles were compared according to patient karyotype. No difference was found in the number of retrieved oocytes (8.9 ± 5.5 vs 8.5 ± 4.7; p=0.56) or the number of mature oocytes (7.4 ± 4.7 vs 6.9 ± 4.2; p=0.49) between the 45,X/46,XX group and the 46,XX group, respectively. Fertilization rates did not differ between the groups for either IVF or ICSI. In addition, no difference was found in the pregnancy rate by cycle (17.4% vs 18.7%, respectively; p=0.87). The percentage of first-trimester miscarriages was similar in both groups (13.6% vs 12.5%, respectively; p=0.51). 45,X/46,XX mosaicism with 6-28% of aneuploidy has no adverse effect on the outcomes of IVF or ICSI among women referred to assisted reproductive technologies.

    46,XX male sex reversal occurs in approximately 1: 20 000 live births and is most commonly caused by interchromosomal translocations of the Y-linked sex-determining gene, SRY. Rearrangements of the closely related SOX3 gene on the X chromosome are also associated with 46,XX male sex reversal. It has been hypothesized that sex reversal in the latter is caused by ectopic expression of SOX3 in the developing urogenital ridge where it triggers male development by acting as an analog of SRY. However, altered regulation of SOX3 in individuals with XX male sex reversal has not been demonstrated. Here we report a boy with SRY-negative XX male sex reversal who was diagnosed at birth with a small phallus, mixed gonads, and borderline-normal T. Molecular characterization of the affected individual was performed using array comparative genomic hybridization, fluorescent in situ hybridization of metaphase chromosomes, whole-genome sequencing, and RT-PCR expression analysis of lymphoblast cell lines. The affected male carries ∼774-kb insertion translocation from chromosome 1 into a human-specific palindromic sequence 82 kb distal to SOX3. Importantly, robust SOX3 expression was identified in cells derived from the affected individual but not from control XX or XY cells, indicating that the translocation has a direct effect on SOX3 regulation. This is the first demonstration of altered SOX3 expression in an individual with XX male sex reversal and suggests that SOX3 can substitute for SRY to initiate male development in humans.

  14. La persistencia del surrealismo en la arquitectura religiosa española del siglo XX

    Full Text Available Este artículo trata de averiguar si el surrealismo —no entendido tanto como estilo artístico, sino como manera compleja de entender la vida— puede postularse como hilo conductor de la arquitectura religiosa del siglo XX en España. Aunque es posible leer la arquitectura católica moderna como un intento de integrar el dogma con las aspiraciones del llamado espíritu de los tiempos, la pérdida de peso que supuso este planteamiento para la arquitectura todavía no se ha esclarecido lo suficiente. La pervivencia de las tradiciones, el diálogo entre la teología y el arte o la crisis de identidad católica tras el Concilio Vaticano II son facetas del intenso —y a veces obsesivo— debate que se desarrolló en España durante el siglo XX. A la postre, se constata que la perenne vena surrealista que subyace en todo lo español impregna también la arquitectura sacra y dificulta su correcta lectura. Se evidencia, finalmente, que la arquitectura religiosa es susceptible de miradas transversales sobre el hecho construido y que abre el campo a nuevas interpretaciones.

    Time-series photometric observations were made for the SX Phoenicis star XX Cyg between 2007 and 2011 at the Xinglong Station of National Astronomical Observatories of China. With the light curves derived from the new observations, we do not detect any secondary maximum in the descending portion of the light curves of XX Cyg, as reported in some previous work. Frequency analysis of the light curves confirms a fundamental frequency f 0 = 7.4148 cycles day –1 and up to 19 harmonics, 11 of which are newly detected. However, no secondary mode of pulsation is detected from the light curves. The O–C diagram, produced from 46 newly determined times of maximum light combined with those derived from the literature, reveals a continuous period increase with the rate of (1/P)(dP/dt) = 1.19(13) × 10 –8 yr -1 . Theoretical rates of period change due to the stellar evolution were calculated with a modeling code. The result shows that the observed rate of period change is fully consistent with period change caused by evolutionary behavior predicted by standard theoretical models.

    The purpose of the present study was to investigate whether ten unrelated SRY-negative individuals with this sex differentiation disorder presented a double dose of SOX9 as the cause of their disease. Ten unrelated SRY-negative 46,XX ovotesticular disorder of sexual development (DSD) subjects were molecularly studied. Multiplex-ligation dependent probe amplification (MLPA) and quantitative real-time PCR analysis (qRT-PCR) for SOX9 were performed. The MLPA analysis demonstrated that one patient presented a heterozygous duplication of the entire SOX9 coding region (above 1.3 value of peak ratio), as well as at least a ~ 483 kb upstream duplication. Moreover, no duplication of other SOX9 probes was observed corresponding to the region between -1007 and -1500 kb upstream. A qRT-PCR analysis showed a duplication of at least -581 kb upstream and ~1.63 kb of the coding region that encompasses exon 3. The limits of the duplication were mapped approximately from ~71539762 to 72122741 of Chr17. No molecular abnormalities were found in the remaining nine patients. This study is thought to be the first report regarding a duplication of SOX9 that is associated with the presence of 46,XX ovotesticular DSD, encompassing at least -581 kb upstream, and the almost entire coding region of the gene.

    Seismic design and evaluation criteria for DOE facilities are provided in DOE-STD-1020-XX. The criteria include selection of design/evaluation seismic input from probabilistic seismic hazard curves combined with commonly practiced deterministic response evaluation methods and acceptance criteria with controlled levels of conservatism. Conservatism is intentionally introduced in specification of material strengths and capacities, in the allowance of limited inelastic behavior and by a seismic load factor. These criteria are based on the performance or risk goals specified in DOE 5480.28. Criteria have been developed following a graded approach for several performance goals ranging from that appropriate for normal-use facilities to that appropriate for facilities involving hazardous or critical operations. Performance goals are comprised of desired behavior and of the probability of not achieving that behavior. Following the seismic design/evaluation criteria of DOE-STD-1020-XX is sufficient to demonstrate that the probabilistic performance or risk goals are achieved. The criteria are simple procedures but with a sound, rigorous basis for the achievement of goals

    Full Text Available The article deals with the issues of censorship and printing in the Caucasus at the end of XIX – early XX centuries. The special attention is given to censorship during the First Russian revolution (1905-1907 years. Among the materials are the archival documents from the national archives of Georgia, as well as materials of pre-revolutionary periodicals and legislation dedicated to this issue. The scientific publications are important too. The authors come to the conclusion that in the late of XIX – early XX centuries in the Caucasus, as in the whole of the territory of the Russian Empire, there was a sharp rise of printing and publishing periodicals – magazines. With the growth of revolutionary events there was a need in the institute of censorship to control over the printed word. Especially the role of this institution was high during the First Russian revolution. Despite the small number of states and different problems, the censorship has contributed to the stabilization of the political and crime situation in the territory of the Caucasian viceroyalty.

    Purpose: The quality assurance (QA) procedure has to check the most relevant beam parameters to ensure the delivery of the correct dose to patients. Film dosimetry, which is commonly used for scanned ion beam QA, does not provide immediate results. The purpose of this work is to answer whether, for scanned ion beam therapy, film dosimetry can be replaced with the 2D MatriXX detector as a real-time tool. Methods: MatriXX, equipped with 32×32 parallel plate ion-chambers, is a commercial device intended for pre-treatment verification of conventional radiation therapy.The MatriXX, placed at the isocenter, and GAFCHROMIC films, positioned on the MatriXX entrance, were exposed to 131.44 MeV proton and 221.45 MeV/u Carbon-ion beams.The OmniPro-I’mRT software, applied for the data taking of MatriXX, gives the possibility of acquiring consecutive snapshots. Using the NI LabVIEW, the data from snapshots were logged as text files for further analysis. Radiochromic films were scanned with EPSON scanner and analyzed using software programs developed in-house for comparative purposes. Results: The field dose uniformity, flatness, beam position and beam width were investigated. The field flatness for the region covering 6×6 cm{sup 2} square field was found to be better than 2%. The relative standard deviations, expected to be constant over 2×2, 4×4 and 6×6 pixels from MatriXX measurement gives a uniformity of 1.5% in good agreement with the film results.The beam center position is determined with a resolution better than 200 µm for Carbon and less than 100 µm for proton beam.The FWHM determination for a beam wider than 10 mm is satisfactory, whilst for smaller beams the determination is uncertain. Conclusion: Precise beam position and fast 2D dose distribution can be determined in real-time using MatriXX detector. The results show that MatriXX is quick and accurate enough to be used in charged-particle therapy QA.

    2016-08-01

    To provide a review of sustainable sizing practices that reduce waste, increase sales, and simultaneously produce safer, better fitting, accommodating products. Sustainable sizing involves a set of methods good for both the environment (sustainable environment) and business (sustainable business). Sustainable sizing methods reduce (1) materials used, (2) the number of sizes or adjustments, and (3) the amount of product unsold or marked down for sale. This reduces waste and cost. The methods can also increase sales by fitting more people in the target market and produce happier, loyal customers with better fitting products. This is a mini-review of methods that result in more sustainable sizing practices. It also reviews and contrasts current statistical and modeling practices that lead to poor fit and sizing. Fit-mapping and the use of cases are two excellent methods suited for creating sustainable sizing, when real people (vs. virtual people) are used. These methods are described and reviewed. Evidence presented supports the view that virtual fitting with simulated people and products is not yet effective. Fit-mapping and cases with real people and actual products result in good design and products that are fit for person, fit for purpose, with good accommodation and comfortable, optimized sizing. While virtual models have been shown to be ineffective for predicting or representing fit, there is an opportunity to improve them by adding fit-mapping data to the models. This will require saving fit data, product data, anthropometry, and demographics in a standardized manner. For this success to extend to the wider design community, the development of a standardized method of data collection for fit-mapping with a globally shared fit-map database is needed. It will enable the world community to build knowledge of fit and accommodation and generate effective virtual fitting for the future. A standardized method of data collection that tests products' fit methodically

Además, se caracterizó a ese segmento poblacional a partir de diferentes variables: sexo, edad, estado civil y distribución geográfica. También se abordaron otros aspectos como fueron: alfabetismo, nivel de educación, ocupación, jefatura de hogar y vivienda. Entre los hallazgos más destacables se encuentra la permanencia, en los registros censales del siglo XX, de un concepto de discapacidad basado en la deficiencia, lo que definió los criterios de clasificación para esa población en esas fuentes. Asimismo se constató, por una parte, la asociación entre discapacidad e inequidad en esa centuria y, por la otra, la fragilidad de los vínculos de parentesco en ese grupo poblacional con respecto al conjunto de hogares de Costa Rica a fines de ese siglo. Las fuentes empleadas en esta investigación fueron los censos de población de Costa Rica del siglo XX.

    There have been considerable advances concerning understanding of the early and later stages of ovarian development; a number of genes have been implicated and their mutations have been associated with developmental abnormalities. The most important genes controlling the initial phase of gonadal development, identical in females and males, are Wilms' tumor suppressor 1 (WT1) and steroidogenic factor 1 (SF1). Four genes are likely to be involved in the subsequent stages of ovarian development (WNT4, DAX1, FOXL2 and RSPO1), but none is yet proven to be the ovarian determining factor. Changes in nomenclature and classification were recently proposed in order to incorporate genetic advances and substitute gender-based diagnostic labels in terminology. The term "disorders of sex development" (DSD) is proposed to substitute the previous term "intersex disorders". Three main categories have been used to describe DSD in the 46,XX individual: 1) disorders of gonadal (ovarian) development: ovotesticular DSD, previously named true hermaphroditism, testicular DSD, previously named XX males, and gonadal dysgenesis; 2) disorders related to androgen excess (congenital adrenal hyperplasia, aromatase deficiency and P450 oxidoreductase deficiency); and 3) other rare disorders. In this mini-review, recent advances concerning development of the genital system in 46,XX individuals and related abnormalities are discussed. Basic embryology of the ovary and molecular pathways determining ovarian development are reviewed, focusing on mutations disrupting normal ovarian development. Disorders of sex development according to the revised nomenclature and classification in 46,XX individuals are summarized, including genetic progress in the field.

    A 33-year-old woman was hospitalized for examination of edematous laryngopharynx. She was acromegalic. A pituitary adenoma with elevated serum levels of growth hormone (GH) and insulin-like growth factor-I (IGF-I) was detected, indicating acromegaly caused by GH-secreting pituitary adenoma. Multiple pigmented nevi were also noted without overt short stature and cubitus valgus. Chromosome analysis revealed that she had contracted Turner syndrome with 47,XXX/45,X/46,XX mosaicism. Transsphenoidal resection of the tumor decreased serum GH and IGF-I levels, but the edema was not improved. Both premature ovarian failure and hypertension appeared after surgery. This case may indicate the important relationships between GH/IGF-I and Turner syndrome.

    Triploid mosaicism is a rare aneuploidy syndrome characterized by growth retardation, developmental delay, 3-4 syndactyly, microphthalmia, coloboma, cleft lip and/or palate, genitourinary anomalies, and facial or body asymmetry. In the present report, we describe a 3-month-old female presenting with failure to thrive, growth retardation, and developmental delay. A chromosomal microarray demonstrated monosomy X, but her atypical phenotype prompted further evaluation with a chromosome analysis, which demonstrated 45,X/68,XX mixoploidy. To our knowledge, this is the first report of a patient with this chromosome complement. Mosaicism in chromosomal aneuploidies is likely under-recognized and may obscure the clinical diagnosis. At a time when comparative genomic hybridization and genome sequencing are increasingly used as diagnostic tools, this report highlights the clinical utility of chromosome analysis when a molecular diagnosis is not consistent with the observed phenotype. © 2015 Wiley Periodicals, Inc.

  4. Universal corrections to scaling for block entanglement in spin-1/2 XX chains

    International Nuclear Information System (INIS)

    Calabrese, Pasquale; Essler, Fabian H L

    2010-01-01

    We consider the Rényi entropies S n (l) in the one-dimensional spin-1/2 Heisenberg XX chain in a magnetic field. The case n = 1 corresponds to the von Neumann 'entanglement' entropy. Using a combination of methods based on the generalized Fisher–Hartwig conjecture and a recurrence relation connected to the Painlevé VI differential equation we obtain the asymptotic behaviour, accurate to order O(l -3 ), of the Rényi entropies S n (l) for large block lengths l. For n = 1, 2, 3, 10 this constitutes the 3, 6, 10, 48 leading terms respectively. The o(1) contributions are found to exhibit a rich structure of oscillatory behaviour, which we analyse in some detail both for finite n and in the limit n→∞

    In this work, we investigate the quantum-memory-assisted entropic uncertainty relation in a two-qubit Heisenberg XX model with inhomogeneous magnetic field. It has been found that larger coupling strength J between the two spin-chain qubits can effectively reduce the entropic uncertainty. Besides, we observe the mechanics of how the inhomogeneous field influences the uncertainty, and find out that when the inhomogeneous field parameter b1. Intriguingly, the entropic uncertainty can shrink to zero when the coupling coefficients are relatively large, while the entropic uncertainty only reduces to 1 with the increase of the homogeneous magnetic field. Additionally, we observe the purity of the state and Bell non-locality and obtain that the entropic uncertainty is anticorrelated with both the purity and Bell non-locality of the evolution state.

  6. Diverging conductance at the contact between random and pure quantum XX spin chains

    2017-11-01

    A model consisting of two quantum XX spin chains, one homogeneous and the second with random couplings drawn from a binary distribution, is considered. The two chains are coupled to two different non-local thermal baths and their dynamics is governed by a Lindblad equation. In the steady state, a current J is induced between the two chains by coupling them together by their edges and imposing different chemical potentials μ to the two baths. While a regime of linear characteristics J versus Δμ is observed in the absence of randomness, a gap opens as the disorder strength is increased. In the infinite-randomness limit, this behavior is related to the density of states of the localized states contributing to the current. The conductance is shown to diverge in this limit.

A partir dessas representações, o que se pretende discutir aqui, embasado inicialmente nos conceitos de “mundo demoníaco” e “mundo divino” de Northrop Frye, é a relação de estreita interdependência e assimilação que marca espaços aparentemente antagônicos e inconciliáveis.

    This report presents the contribution of the ARCAL XX project 'Guidelines for the Control of Radiation Sources' for the development and harmonization of the safety of radiation sources in Latin America. The project began in 1997 with the participation of nine countries. The methodology adopted has enabled all experts from the nine countries involved in the project to participate in discussions on the development of guidelines based on regional experience. Three common documents for all practices and six safety guides for the main practices have been revised for publication. For the next two years, the project co-ordinators are proposing regional and national workshops for the application of the safety guides approved by the ARCAL programme. (author)

    The objectives of the ARCAL XX Project: 'Guidelines on Control of Radiation Sources' (1997-2000) are to promote an effective control of the radiation sources used in medicine, industrial and research applications, harmonising and updating existing procedures within Latin American, adopting the International Basic Safety Standards, in order to avoid unnecessary expositions limiting the probability of accidents occurrence. Nine countries participate with experts in the development of guidelines based in the regional experience. The guidelines contain Radiological Safety Requirements, Guide for Authorisation Application and Inspections Procedures. At this moment, there are guidelines for Radiotherapy, Nuclear Medicine and Diagnostic Radiology. The implementation of these guidelines will improve the effectiveness of regulatory control of radiation sources in Latin American and the radiological protection in aspects of occupational, medical, public and potential exposure. This document presents the experience in the development of these guidelines and their contribution for elaborating national regulations in medical practices. (author) [es

    Full Text Available The former industrialization of Magallanes was a particular economic phenomena that typified the boom and development of the southern Chilena territory during the period between the last decade of the XIX century and the first two decades of the XX century. In a context of geographic isolation and remoteness served as a encouragement to the satisfaction of numerous requirements of service needs and supplies of goods, that the importing from Europe did not fulfill in time due. It was at he same time an evidence of the creativity, intelligence, and vigor of the Europeans immigrants, that contribute to the Magellan autonomy and self-sufficiency during a decisive span of its history.

    Collagen α1 type XX, which contains fibronectin type III (FN3) repeats involving six FN3 domains (referred to as the FN#1-FN#6 domains), is an unusual member of the fibril-associated collagens with interrupted triple helices (FACIT) subfamily of collagens. The results of standard protein BLAST suggest that the FN3 repeats might contribute to collagen α1 type XX acting as a cytokine receptor. To date, solution NMR structures of the FN#3, FN#4 and FN#6 domains have been determined. To obtain further structural evidence to understand the relationship between the structure and function of the FN3 repeats from collagen α1 type XX, the crystal structure of the FN#2 domain from human collagen α1 type XX (residues Pro386-Pro466; referred to as FN2-HCXX) was solved at 2.5 Å resolution. The crystal structure of FN2-HCXX shows an immunoglobulin-like fold containing a β-sandwich structure, which is formed by a three-stranded β-sheet (β1, β2 and β5) packed onto a four-stranded β-sheet (β3, β4, β6 and β7). Two consensus domains, tencon and fibcon, are structural analogues of FN2-HCXX. Fn8, an FN3 domain from human oncofoetal fibronectin, is the closest structural analogue of FN2-HCXX derived from a naturally occurring sequence. Based solely on the structural similarity of FN2-HCXX to other FN3 domains, the detailed functions of FN2-HCXX and the FN3 repeats in collagen α1 type XX cannot be identified.

    In Nile tilapia (Oreochromis niloticus), individuals with atypical sexual genotype are commonly used in farming (use of YY males to produce all-male offspring), but they also constitute major tools to study sex determinism mechanisms. In other species, sexual genotype and sex reversal procedures affect different aspects of biology, such as growth, behavior and reproductive success. The aim of this study was to assess the influence of sexual genotype on sperm quality in Nile tilapia. Milt characteristics were compared in XX (sex-reversed), XY and YY males in terms of gonadosomatic index, sperm count, sperm motility and duration of sperm motility. Sperm motility was measured by computer-assisted sperm analysis (CASA) quantifying several parameters: total motility, progressive motility, curvilinear velocity, straight line velocity, average path velocity and linearity. None of the sperm traits measured significantly differed between the three genotypes. Mean values of gonadosomatic index, sperm concentration and sperm motility duration of XX, XY and YY males, respectively ranged from 0.92 to 1.33%, from 1.69 to 2.22 ×10(9) cells mL(-1) and from 18'04″ to 27'32″. Mean values of total motility and curvilinear velocity 1 min after sperm activation, respectively ranged from 53 to 58% and from 71 to 76 μm s(-1) for the three genotypes. After 3 min of activity, all the sperm motility and velocity parameters dropped by half and continued to slowly decrease thereafter. Seven min after activation, only 9 to 13% of spermatozoa were still progressive. Our results prove that neither sexual genotype nor hormonal sex reversal treatments affect sperm quality in male Nile tilapias with atypical sexual genotype. Copyright © 2012 Elsevier Inc.

    Full Text Available La formación del discurso en salud mental durante la primera mitad del siglo XX tiene en el Movimiento de Higiene Mental y en el Comité Nacional de Higiene Mental sus principales influencias. Como depositarios de un estilo de pensamiento biomédico, los dos entes mencionados tomaron la vocería en el campo de la salud mental, el cual para la época bajo estudio adolecía de una clara diferenciación conceptual. Con el objeto de comprender la influencia que ejerció este estilo de pensamiento en la formación del discurso en salud mental durante la primera mitad del siglo XX, se desarrollo una revisión de literatura de la época, empleando para tal fin una propuesta teórica que combinó el análisis del discurso de Michel Foucault y la sociología del conocimiento de Ludwik Fleck. Los resultados evidencian una hegemonía del estilo de pensamiento biomédico para abordar la salud mental, representada principalmente en el empleo de la prevención como estrategia de trabajo; de igual forma se constató que fueron los médicos, psiquiatras y salubristas de la época quienes asumieron para sí, como colectivo de pensamiento, la autoridad para hablar y actuar sobre la salud mental de la población, relegando a un segundo plano otros colectivos de pensamiento.

    In congenital adrenal hyperplasia (CAH) with ambiguous genitalia, assigning gender of rearing can be complex, especially If genitalia is highly virilized. Apart from karyotype, prenatal androgen exposure, patient's gender orientation, sociocultural, and parental influences play a role. The aim of this study was to assess gender dysphoria and psychosocial issues in patients of CAH raised as males and females. This is a cross-sectional study that includes patients (old and new) with CAH who were treated by us in the last 6 months. A semi-structured interview proforma was used to elicit history and psychosocial background of the patients. The clinical and biochemical details were noted. For psychological analysis, patients were screened for gender dysphoria using Parent Report Gender Identity Questionnaire for children Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults. We analyzed 22 46 XX CAH patients among which, 3 were reared as males and 19 as females. Among the 19 patients reared as females, 17 patients showed no gender dysphoria. Two patients revealed gender dysphoria as indicated by their marginally low scores on the gender dysphoria assessment. However, in view of current literature and the age groups of the patients, behavior of the 6-year-old patient can be best understood as being tomboyish. Gender dysphoria in the 22-year-old can be explained by the dominance of psychosocial factors and not hormones alone. Among the three patients reared as males, two prepubertal were satisfied with their male gender identity. The third patient, aged 32 years, had gender dysphoria when reared as a male that resolved when gender was reassigned as female and feminizing surgery was done. Gender assignment in 46 XX CAH is guided by factors such as degree of virilization of genitalia, gender orientation, patient involvement, sociocultural, and parental influences.

The basic idea is concerned with fiction of the authors, which seek to destroy Genesis and alter reality, which in no way satisfied with the artists.The purpose of the article is identifying of the specifics of literary and imaginative reconstruction of historical events in the novels of M. Kuzmin and Sasha Sokolov by analyzing specifications of its narration.Method or the methodology of work: Among research material are M. Kuzmin’s novel "A wonderful life of Joseph Balsamo, count Cagliostro" and Sasha Sololov’s novel "Palisandria". Analyzing the texts of works on the researched topic were used comparative-historical, historical-biographical and structural methods.Results: Our study suggests that irony and parody in biographical and memorialistic genres of XX century have integrated, multifunctional meaning. Analysis of the novels allows us to observe the transformation of traditional biographical memorialistic narration into the grotesque model of the reality. There are interesting observations of the functioning in the works such approaches as parody, travesty, illogic, allegory, etc. As a result of the use of similar artistic techniques the novels become metatext about human nature in generalPractical implications: The results of our research can be used for lectures on the history of Russian literature of XXth century, in the course "History of Russian Literature" at faculties and departments of Russian Philology institutes and universities.

    The shakeout in the solar cell and module industry is in full swing. While the number of companies and production locations shutting down in the Western world is increasing, the capacity expansion in the Far East seems to be unbroken. Size in combination with a good sales network has become the key to success for surviving in the current storm. The trade war with China already looming on the horizon is adding to the uncertainties.

  5. XX Disorder of Sex Development is associated with an insertion on chromosome 9 and downregulation of RSPO1 in dogs (Canis lupus familiaris.

    Vicki N Meyers-Wallen

    Full Text Available Remarkable progress has been achieved in understanding the mechanisms controlling sex determination, yet the cause for many Disorders of Sex Development (DSD remains unknown. Of particular interest is a rare XX DSD subtype in which individuals are negative for SRY, the testis determining factor on the Y chromosome, yet develop testes or ovotestes, and both of these phenotypes occur in the same family. This is a naturally occurring disorder in humans (Homo sapiens and dogs (C. familiaris. Phenotypes in the canine XX DSD model are strikingly similar to those of the human XX DSD subtype. The purposes of this study were to identify 1 a variant associated with XX DSD in the canine model and 2 gene expression alterations in canine embryonic gonads that could be informative to causation. Using a genome wide association study (GWAS and whole genome sequencing (WGS, we identified a variant on C. familiaris autosome 9 (CFA9 that is associated with XX DSD in the canine model and in affected purebred dogs. This is the first marker identified for inherited canine XX DSD. It lies upstream of SOX9 within the canine ortholog for the human disorder, which resides on 17q24. Inheritance of this variant indicates that XX DSD is a complex trait in which breed genetic background affects penetrance. Furthermore, the homozygous variant genotype is associated with embryonic lethality in at least one breed. Our analysis of gene expression studies (RNA-seq and PRO-seq in embryonic gonads at risk of XX DSD from the canine model identified significant RSPO1 downregulation in comparison to XX controls, without significant upregulation of SOX9 or other known testis pathway genes. Based on these data, a novel mechanism is proposed in which molecular lesions acting upstream of RSPO1 induce epigenomic gonadal mosaicism.

    Remarkable progress has been achieved in understanding the mechanisms controlling sex determination, yet the cause for many Disorders of Sex Development (DSD) remains unknown. Of particular interest is a rare XX DSD subtype in which individuals are negative for SRY, the testis determining factor on the Y chromosome, yet develop testes or ovotestes, and both of these phenotypes occur in the same family. This is a naturally occurring disorder in humans (Homo sapiens) and dogs (C. familiaris). Phenotypes in the canine XX DSD model are strikingly similar to those of the human XX DSD subtype. The purposes of this study were to identify 1) a variant associated with XX DSD in the canine model and 2) gene expression alterations in canine embryonic gonads that could be informative to causation. Using a genome wide association study (GWAS) and whole genome sequencing (WGS), we identified a variant on C. familiaris autosome 9 (CFA9) that is associated with XX DSD in the canine model and in affected purebred dogs. This is the first marker identified for inherited canine XX DSD. It lies upstream of SOX9 within the canine ortholog for the human disorder, which resides on 17q24. Inheritance of this variant indicates that XX DSD is a complex trait in which breed genetic background affects penetrance. Furthermore, the homozygous variant genotype is associated with embryonic lethality in at least one breed. Our analysis of gene expression studies (RNA-seq and PRO-seq) in embryonic gonads at risk of XX DSD from the canine model identified significant RSPO1 downregulation in comparison to XX controls, without significant upregulation of SOX9 or other known testis pathway genes. Based on these data, a novel mechanism is proposed in which molecular lesions acting upstream of RSPO1 induce epigenomic gonadal mosaicism.

    Estimation of the soil volume affected by roots - the rhizosphere - is crucial to assess the effects of plants on properties and processes in soils and dynamics of nutrients, water, microorganisms and soil organic matter. The challenges to assess the rhizosphere size are: 1) the continuum of properties between the root surface and root-free soil, 2) differences in the distributions of various properties (carbon, microorganisms and their activities, various nutrients, enzymes, etc.) along and across the roots, 3) temporal changes of properties and processes. Thus, to describe the rhizosphere size and root effects, a holistic approach is necessary. We collected literature and own data on the rhizosphere gradients of a broad range of physico-chemical and biological properties: pH, CO2, oxygen, redox potential, water uptake, various nutrients (C, N, P, K, Ca, Mg, Mn and Fe), organic compounds (glucose, carboxylic acids, amino acids), activities of enzymes of C, N, P and S cycles. The collected data were obtained based on the destructive approaches (thin layer slicing), rhizotron studies and in situ visualization techniques: optodes, zymography, sensitive gels, 14C and neutron imaging. The root effects were pronounced from less than 0.5 mm (nutrients with slow diffusion) up to more than 50 mm (for gases). However, the most common effects were between 1 - 10 mm. Sharp gradients (e.g. for P, carboxylic acids, enzyme activities) allowed to calculate clear rhizosphere boundaries and so, the soil volume affected by roots. The first analyses were done to assess the effects of soil texture and moisture as well as root system and age on these gradients. The most properties can be described by two curve types: exponential saturation and S curve, each with increasing and decreasing concentration profiles from the root surface. The gradient based distribution functions were calculated and used to extrapolate on the whole soil depending on the root density and rooting intensity. We

    Full Text Available The article is devoted to the history of anti-corruption and bribery as one of its kinds in the Russian Empire. Corruption as a complex social phenomenon that occurs in the process of socio-economic, political and social relations has become one of the most pressing political, social and economic problems of modern Russia. The corruption in the state apparatus not only cause serious, sometimes unsolvable problems for the citizens, but also hinder the normal functioning of the administrative bodies and authorities. The legal component, the development and adoption of relevant laws perform a special role in combating corruption. For many centuries government has repeatedly attempted if not to eliminate or at least to curb corruption in numerous managerial and administrative apparatus. The greatest interest in this regard is the imperial period of Russian history. The authors study the history of the development of criminal and civil law in the Code of the Russian Empire Publishing Laws 1832 of the penal Code and criminal Corrections 1845 judicial statutes in 1864 and subsequent legislation late XIX – the beginning of the XX century, the history of the development of appropriate laws, trace the change in order to prosecute and the degree of responsibility of the officials on the basis of unpublished material of the State Council, the State Duma and the Ministry of Justice, are stored in the Russian State Historical Archive, as well as the published acts of the Russian legislation, the verbatim records of the State Duma and the Council of State.

    In this study, the annual cycle of the gonadal steroids testosterone (T), 11-ketotestosterone (11-KT), 17β-oestradiol (E2) and 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) was determined using radioimmunoassay and then compared, for XY males (n=35) and sex-reversed XX males (n=27) rainbow trout, to establish possible endocrinology differences. Both in XY males and sex-reversed XX males, significant correlation was shown between body weight and T (r=0.5046 and 0.34078, respectively; psex-reversed XX males were similar and showed an intense seasonal variation. The highest levels for T and 11-KT were detected from December to April with a peak in January (51.67 ± 5.11 and 61.95 ± 4.25 ng/ml, for XY males and 57.1 ± 5.82 and 59.27 ± 4.84 ng/ml, respectively, for XX males). In addition, there was a positive correlation (psex-reversed XX males (r=0.6019). Concentrations of DHP in XY males also showed seasonal variation with a peak in February (25.18 ± 12.99 ng/ml). However, DHP levels in sex-reversed XX males were undetectable (sex-reversed XX males were similar to those observed in XY males. The only difference in the annual gonadal steroid cycle between XY and sex-reversed XX males was in the DHP profile. © 2009 Blackwell Verlag GmbH.

    XX male is a rare sex chromosomal disorder in infertile men. The purpose of this study was to distinguish the clinical and genetic features of the 46,XX male syndrome from other more frequent, testicular-origin azoospermic causes of male infertility. To study 46,XX male syndrome, we compared clinical and endocrinological parameters to other groups with testicular-origin azoospermia, and to an age-matched group of healthy males and females as normal control. Fluorescent in situ hybridization for detection and localization of the sex-determining region of the Y gene (SRY), array-based comparative genomic hybridization screening, and real-time qualitative polymerase chain reaction of FGF9, WT1, NR5A1, and SPRY2 genes were performed in this genetic investigation. Our three patients with 46,XX male syndrome had a much higher follicular-stimulating hormone level, lower body height, lower testosterone level, and ambiguous external genitalia. One of the three patients with 46,XX male syndrome was SRY-negative. A further genetic study, including a comparative genomic hybridization array and real-time polymerase chain reaction, showed a gain of FGF9 copy numbers only in the SRY-negative 46,XX male. The genetic copy number of the FGF9 gene was duplicated in that case compared to the normal female control and was significantly lower than that of the normal male control. No such genomic gain was observed in the case of the two SRY-positive 46,XX males. Similar to clinical manifestations of 46,XX male syndrome, genetic evidence in this study suggests that FGF9 may contribute to sex reversal, but additional confirmation with more cases is still needed.

    It is well accepted that Forkhead box protein L2 (Foxl2) and aromatase (Cyp19a1; the enzyme responsible for estrogen synthesis) are critical for ovarian development in vertebrates. Knockouts of Foxl2 and Cyp19a1 in goat, mouse, and zebrafish have revealed similar but not identical functions across species. Functional analyses of these two genes in other animals are needed to elucidate their conserved roles in vertebrate sexual development. In this study, we established foxl2 and cyp19a1a mutant lines in Nile tilapia. Both foxl2-/- and cyp19a1a-/- XX fish displayed female-to-male sex reversal. Sf1, Dmrt1, and Gsdf were upregulated in the foxl2-/- and the cyp19a1a-/- XX gonads. Downregulation of Cyp19a1a and serum estradiol-17β level, and upregulation of Cyp11b2 and serum 11-ketotestosterone level were observed in foxl2-/- XX fish. The mutant phenotype of foxl2-/- XX individuals could be rescued by 17β-estradiol treatment from 5 to 30 days after hatching (dah). Upregulation of Star1, the enzyme involved in androgen production in tilapia, was also observed in the foxl2-/- XX gonad at 30 and 90 dah. In vitro promoter analyses consistently demonstrated that Foxl2 could suppress the transcription of star1 in a dose-dependent manner. In addition, compared with the control XX gonad, fewer germ cells were detected in the foxl2-/- XX, cyp19a1a-/- XX, and control XY gonads 10 dah. These results demonstrate that Foxl2 promotes ovarian development by upregulating Cyp19a1a expression and repressing male pathway gene expression. These results extend the study of Foxl2 and Cyp19a1a loss of function to a commercially important fish species. Copyright © 2017 Endocrine Society.

  20. XY sex chromosome complement, compared with XX, in the CNS confers greater neurodegeneration during experimental autoimmune encephalomyelitis.

    Women are more susceptible to multiple sclerosis (MS) and have more robust immune responses than men. However, men with MS tend to demonstrate a more progressive disease course than women, suggesting a disconnect between the severity of an immune attack and the CNS response to a given immune attack. We have previously shown in an MS model, experimental autoimmune encephalomyelitis, that autoantigen-sensitized XX lymph node cells, compared with XY, are more encephalitogenic. These studies demonstrated an effect of sex chromosomes in the induction of immune responses, but did not address a potential role of sex chromosomes in the CNS response to immune-mediated injury. Here, we examined this possibility using XX versus XY bone marrow chimeras reconstituted with a common immune system of one sex chromosomal type. We found that experimental autoimmune encephalomyelitis mice with an XY sex chromosome complement in the CNS, compared with XX, demonstrated greater clinical disease severity with more neuropathology in the spinal cord, cerebellum, and cerebral cortex. A candidate gene on the X chromosome, toll-like receptor 7, was then examined. Toll-like receptor 7 expression in cortical neurons was higher in mice with XY compared with mice with XX CNS, consistent with the known neurodegenerative role for toll-like receptor 7 in neurons. These results suggest that sex chromosome effects on neurodegeneration in the CNS run counter to effects on immune responses, and may bear relevance to the clinical enigma of greater MS susceptibility in women but faster disability progression in men. This is a demonstration of a direct effect of sex chromosome complement on neurodegeneration in a neurological disease.

    We assess the outcome in 46,XX men with congenital adrenal hyperplasia who were born with Prader 4 or 5 genitalia and assigned male gender at birth. After receiving institutional review board approval and subject consent we reviewed the medical records of 12 men 35 to 69 years old with 46,XX congenital adrenal hyperplasia, of whom 6 completed social and gender issue questionnaires. All subjects were assigned male gender at birth, were diagnosed with virilizing congenital adrenal hyperplasia at age greater than 3 years and indicated a male gender identity with sexual orientation to females. Ten of the 12 subjects had always lived as male and 2 who were reassigned to female gender in childhood subsequently self-reassigned as male. Nine of the 12 men had long-term female partners, including 7 married 12 years or more. The 3 subjects without a long-term female partner included 1 priest, 1 who was reassigned female gender, married, divorced and self-reassigned as male, and 1 with a girlfriend and sexual activity. All except the priest and the subject who was previously married when female indicated a strong libido and frequent orgasmic sexual activity. Responses to self-esteem, masculinity, body image, social adjustment and symptom questionnaires suggested adjustments related to the extent of familial and social support. Outcome data on severely masculinized 46,XX patients with congenital adrenal hyperplasia who were assigned male gender at birth indicate male gender identity in adulthood with satisfactory male sexual function in those retaining male genitalia. In men who completed questionnaires results were poorer in those lacking familial/social support. Male gender of rearing may be a viable option for parents whose children are born with congenital adrenal hyperplasia, a 46,XX karyotype and male genitalia, although positive parental and other support, and counseling are needed for adjustment.

    The XX male syndrome is a rare genetic disorder. The phenotype is variable; it ranges from a severe impairment of the external genitalia to a normal male phenotype with infertility. It generally results from an unequal crossing over between the short arms of the sex chromosomes (X and Y). We are reporting a case of a 38-year-old man who presented with infertility and the features of hypogonadism and glaucoma. The examinations revealed normal external male genitalia, soft small testes, gynaecomastia and glaucoma. The semen analysis showed azoospermia. The serum gonadotropins were high, with low Anti Mullerian Hormone (AMH) and Inhibin B levels. The chromosomal analysis demonstrated a 46, XX karyotype. Fluorescent In-Situ Hybridization (FISH) and Polymerase Chain Reaction (PCR) revealed the presence of a Sex-determining Region Y (SRY). Testicular Fine Needle Aspiration Cytology (FNAC) revealed the Sertoli Cell Only Syndrome (SCOS). The presence of only Sertoli Cells in the testes, with glaucoma in the XX male syndrome, to our knowledge, has not been reported in the literature.

This was particularly expressed on the terri- tory of the Kingdom of Yugoslavia and Socialist Federal Republic of Yugoslavia (SFRY, were a few independent states were created at the beginning of XX century. All these changes reflected also in the field of culture and science and created ob- stacles for many cultural events, and especially scientific researches of certain phenome- na in these territories at the beginning of the XXI century. These difficulties will continue to be present for many years because the SFRY was disintegrated in wars, violence and crimes resulting in impossibility to establish faster normal collaboration between the newly created states. This problem has not speared even the researches in history of physical culture of the XX century on the territory of former SFRY, because no normal communication bet- ween some of the newly formed states has been established, so the access to researches of primary historic resources, which is necessary in heurictc phase, is lacking. Therefore it is necessary to establish collaboration between colleagues-resear- chers from these territories, more that usually in order to create possibilities for valid researches with objective and worthy conclusions

    Full Text Available El uso de los manuales en economía ha sido masivo en su profesionalización y ha repercutido en las ideas económicas colombianas. Durante el siglo XX se presentaron cuatro etapas; la primera de ellas se dio a inicios del siglo, cuando predominó el autodidactismo en los manuales franceses, entre profesores, políticos y hombres de empresa de Bogotá y Medellín. La segunda etapa se caracterizó por el contacto de algunos protoeconomistas con el pensamiento económico original en el exterior, lo que ocasionó el inicio de la crítica a la utilización de manuales. La tercera surgió con las primeras facultades de Economía, en los años 40, época en que se reemplazó el manual francés por el anglosajón neoclásico; y la última etapa se inicia desde 1980, cuando se hace una crítica coherente al manual y comienza la producción de textos “criollos”, que ofrecen facilidades pedagógicas con pensamiento teórico de vanguardia.

Se advierte la dimensión continental de la emergencia de movimientos, agrupaciones, revistas y autores neovanguardistas a partir de fines de los años 50 y hasta los años 80 al menos. Lo anterior ha producido una nueva semioticidad que emparenta la escritura poética con las artes visuales, escénicas, musicales, audiovisuales y digitales, generando nuevos discursos y nuevos repertorios. Estos procesos suponen el reciclaje y resemantización de los de los ideales antiartísticos de tradición vanguardista y, particularmente, del proyecto arte-vida, revitalizando la relación entre arte y política, en consonancia con los debates públicos y las transformaciones en los sistemas de producción cultural. Se analizan como ejemplos de poesía experimental, visual y accional, a dos poetas chilenos: Cecilia Vicuña y Juan Luis Martínez.

    46,XX male sex reversal syndrome is one of the rarest sex chromosomal aberrations. The presence of SRY gene on one of the X chromosomes is the most frequent cause of this syndrome. Based on Y chromosome profile, there are SRY-positive and SRY-negative forms. The purpose of our study was to report first case series of Iranian patients and describe the different clinical appearances based on their genetic component. From the 8,114 azoospermic and severe oligozoospermic patients referred to Royan institute, we diagnosed 57 cases as sex reversal patients. Based on the endocrinological history, we performed karyotyping, SRY and AZF microdeletion screening. Patients had a female karyotype. According to available hormonal reports of 37 patients, 16 cases had low levels of testosterone (43.2%). On the other hand, 15 males were SRY positive (90.2%), while they lacked the spermatogenic factors encoding genes on Yq. Commencing the testicular differentiation in males, the SRY gene is considered to be very important in this process. Due to homogeneous results of karyotyping and AZF deletion, there are both positive and negative SRY cases that show similar sex reversal phenotypes. Evidences show that there could be diverse phenotypic differences that could be raised from various reasons. © 2016 Blackwell Verlag GmbH.

    Full Text Available El objetivo de este trabajo es analizar los cambios sociodemográficos más significativos ocurridos en los hogares latinoamericanos durante la segunda mitad del siglo xx. Para ello se tienen en cuenta dos aspectos fundamentales: la posible convergencia hacia las familias pequeñas y nucleares; y la naturaleza e incremento de los hogares con jefatura femenina. Se intenta no sólo sintetizar el conocimiento existente sobre dichos temas, sino también dar cuenta de las conexiones entre los cambios sociodemográficos de los hogares y la desigualdad social y de género persistente en América Latina. Algunas de las principales conclusiones son: a A pesar de la existencia de un claro proceso de nuclearización en los hogares latinoamericanos, la importancia de los arreglos familiares de tipo extendido continúa siendo distintiva del sistema familiar en la región, especialmente entre la población de escasos recursos; y b los hogares encabezados por mujeres muestran un claro incremento, y posiblemente éste se aprecie en diversos sectores de nuestras sociedades.

    Steroidogenic factor 1 (NR5A1, SF‐1, Ad4BP) is a transcriptional regulator of genes involved in adrenal and gonadal development and function. Mutations in NR5A1 have been among the most frequently identified genetic causes of gonadal development disorders and are associated with a wide phenotypic spectrum. In 46,XY individuals, NR5A1‐related phenotypes may range from disorders of sex development (DSD) to oligo/azoospermia, and in 46,XX individuals, from 46,XX ovotesticular and testicular DSD to primary ovarian insufficiency (POI). The most common 46,XY phenotype is atypical or female external genitalia with clitoromegaly, palpable gonads, and absence of Müllerian derivatives. Notably, an undervirilized external genitalia is frequently seen at birth, while spontaneous virilization may occur later, at puberty. In 46,XX individuals, NR5A1 mutations are a rare genetic cause of POI, manifesting as primary or secondary amenorrhea, infertility, hypoestrogenism, and elevated gonadotropin levels. Mothers and sisters of 46,XY DSD patients carrying heterozygous NR5A1 mutations may develop POI, and therefore require appropriate counseling. Moreover, the recurrent heterozygous p.Arg92Trp NR5A1 mutation is associated with variable degrees of testis development in 46,XX patients. A clear genotype‐phenotype correlation is not seen in patients bearing NR5A1 mutations, suggesting that genetic modifiers, such as pathogenic variants in other testis/ovarian‐determining genes, may contribute to the phenotypic expression. Here, we review the published literature on NR5A1‐related disease, and discuss our findings at a single tertiary center in Brazil, including ten novel NR5A1 mutations identified in 46,XY DSD patients. The ever‐expanding phenotypic range associated with NR5A1 variants in XY and XX individuals confirms its pivotal role in reproductive biology, and should alert clinicians to the possibility of NR5A1 defects in a variety of phenotypes presenting with gonadal

La incorporación de un número significativo de inmigrantes a finales del siglo XIX junto a un proceso de reorganización productiva asociado al desarrollo de la industria vitivinícola, implicó cambios en las relaciones sociales y en las condiciones de vida de amplios sectores de la población mendocina. Iniciado el siglo XX, la vitivinicultura se convirtió en la principal actividad productiva de la provincia y la más importante en su rubro a nivel nacional. Los viñateros, productores agroindustriales, industriales bodegueros, contratistas de viñas , etc., fueron constituyéndose en parte de una sociedad cada vez más heterogénea y diversa, producto del desarrollo capitalista que experimentó la región desde el último tercio del siglo XIX y que se insertó en el proceso de incorporación de la economía Argentina al mercado mundial. Este período resulta de suma importancia porque se determinó un sistema productivo en torno a la actividad vitivinícola de la provincia que dio forma al mercado de trabajo regional. En este contexto, la inserción de los trabajadores se dio de una manera muy dispar en el proceso productivo, caracterizado por una alta estacionalidad y una escasa especialización de la mano de obra requerida.The aim of this work is to analyze the changes and continuities during the process of formation of the labor market in the province of Mendoza in the early 1900s.

Mucho se sabe acerca del problema de la vivienda en Argentina, sobre todo en el ámbito rioplatense, pero poco se ha profundizado sobre sus características e implicancias en otras regiones tales como en el Noroeste. De este modo, al centrar la atención en Jujuy se rescata no sólo la experiencia jujeña, sino también se develan ciertos rasgos habitacionales compartidos en esta región. A lo largo de este estudio se brindan nuevos aportes que son articulados dentro de aquel conocimiento en el nivel nacional y, cuando ello es posible, también discutidos.This paper examines the housing situation of the population of the province of Jujuy in the first half of the twentieth century, in light of the changes and continuance in the process of local economic growth. Much is known about the problem of housing in Argentina, especially in the River Plate area, but little has been deepened on its characteristics and implications in other regions such as the Northwest. Thus, the focus of the observation in Jujuy not only is rescued this provincial experience but it has also revealed certain housing traits shared in this region. In this study it is provided new contributions that are articulated with the national knowledge and, when possible, also discussed.

    Full Text Available Purpose of the article is to analyze the philosophical and cultural ideas about television, which is a leading visual practice of XX century. It does not lose its relevance in the beginning of the XXI. The role of television lies in visual presentation and formation of the basic norms of taste and traditions of different social groups. Television is the leading communicative practice, which consideration is represented differently in modern science. Research methodology involves an appeal to the philosophical and cultural concepts, representing different approaches to the understanding of television. The paper considers the views of Western scholars, such as R. Arnheim, M. Wolff, A. Kroker, G. Lipovetsky, M. McLuhan, D. Mulvin, J. Mittell, N. Postman, L. Saffhil, J. Sterne, E. Thompson, J. Fiske, S. Shapiro. During analysis of the issue of the specific nature of television content the works of Russian scientists – T. Savitskaya, N. Samutina and Polish contemporary author – R. Sapenko were used. Originality lies in the depiction of the main approaches to the study of television as a visual communicative practice. Deployment of the author's position within the designated issues is presented as a historical digression – from the first attempts at understanding the phenomenon of television to the newest scientific theories that have found expression in contemporary American philosophical and cultural thought. Results of the study can be used in the training course "Visual communication and practices." Conclusions indicated that the majority of contemporary visual practices based on certain patterns, embedded TV. Despite the emergence of new media practices, TV does not lose relevance, everywhere present in the culture, which means that his research will allow a better understanding of the specificity of cultural creativity process.

Se define como trabajador al individuo que se adscribía voluntariamente para trabajar en el recinto de estas unidades productivas, desde españoles pobres, mestizos e indígenas. Los indígenas pertenecían a diversos grupos étnicos, como matlatzincas, otomíes, nahuas. Eran individuos que generalmente carecían de tierra propia. Los trabajadores de las haciendas recibieron diferentes denominaciones que se relacionaban con el cargo o actividad desempeñada. Estos aspectos les daban cierta jerarquía y a la vez dependencia. Existían varias clasificaciones, entre ellas la de los trabajadores permanentes, eventuales o temporales, y arrendatarios.

    A total of 27 competition days, more than 3000 athletes, over 10,000 components of the Olympic family, 3,500 workers, 2,500 volunteers, an overall business of more than 2 billion Euros. These, in a nutshell, are just a few of the data concerning the XX Olympic and the IX Paralympic Winter Games, Torino, Italy, 2006. Such a huge event, obviously required a meticulously organized medical service to cope with the healthcare of the athletes, official workers and the Olympic family, distributed over a geographic area of approximately 80 km in diameter. An ENT service was organized within the medical service, which was divided between 3 Polyclinics, in which 12 ENT Specialists were on duty. The present report gives an account of the final data concerning the service involved, together with a description of the approach used in the actual organization, with a view to providing useful information for colleagues who will be called upon, for a similar service, in future Olympic Winter Games. The ENT healthcare offered was confirmed to be proportional to the requirements, both from a qualitative and quantitative point of view. All the ENT specialists involved, reported having gained an immense store of human experience from having lived the Olympic atmosphere as a volunteer exerting one's own profession. The facilities available in the Polyclinics, which were at a considerable distance from the Hospital, were found to be more than adequate with respect to the pathological conditions and service requested, particularly in 17% of the cases which would otherwise have been sent to a Hospital Outpatient Unit at least 80 km away.

    What is the epidemiology and trajectory of health and socioeconomic status in males with 46,XX disorders of sex development (DSD)? 46,XX DSD males had an increased overall morbidity compared to male background population controls, and the socioeconomic status was inferior on outcome parameters such as education and long-term income. 46,XX DSD males are rare and estimates of prevalence and incidence are limited. An increased morbidity and mortality as well as a negatively affected socioeconomic status are described in males with Klinefelter Syndrome. However, this has never been systematically studied in 46,XX DSD males. In this nationwide registry study including 44 males with a verified diagnosis of 46,XX DSD we aimed to estimate incidence, prevalence and diagnostic delay. Further, we aimed to study morbidity, mortality and socioeconomic outcome parameters using the Danish registries. The socioeconomic outcome parameters were education, income, retirement, parenthood and cohabitation. 46,XX DSD males were born during 1908-2012 and follow-up started at birth or at start of registration and ended in 2014. Potential cases (n = 69) were identified in the Danish Cytogenetic Central Registry and the diagnosis was verified by medical record evaluation (n = 44). A randomly selected age-matched control group of 100 males and 100 females per case was identified by Statistics Denmark. Among newborn males the prevalence of diagnosed 46,XX DSD males was 3.5-4.7 per 100 000. Median age at diagnosis was 17.0 years (range: 0.0-62.8). Overall morbidity was increased compared to male controls (hazard ratio [HR] = 2.4, 95% CI: 1.8-3.3) but not when excluding endocrine and urogenital diseases as well as congenital malformations (HR = 1.2, 95% CI: 0.8-1.6). Mortality was not increased (HR = 0.6, 95% CI: 0.2-2.5) compared to male controls. 46,XX DSD males had poorer education (HR = 0.1, 95% CI: 0.0-0.9) and fewer fatherhoods (HR = 0.4, 95% CI: 0.2-0.7) than male controls

    A disorder of sexual development (DSD) of dogs with a female karyotype, missing SRY gene, and presence of testicles or ovotestes is quite commonly diagnosed. It is suggested that this disorder is caused by an autosomal recessive mutation; however, other models of inheritance have not been definitely ruled out. In an earlier study it was hypothesized that the mutation may reside in a pericentromeric region of canine chromosome 23 (CFA23). Three positional candidate genes (CLASP2, UBP1, and FBXL2) were selected in silico in the search for polymorphisms in 7 testicular or ovotesticular XX DSD dogs, 8 XX DSD dogs of unknown cause (SRY-negative, with enlarged clitoris and unknown histology of gonads), and 29 normal female dogs as a control group. Among the 15 molecularly studied dogs with enlarged clitoris there were 3 new cases of testicular or ovotesticular XX DSD and 4 new cases of XX DSD with unknown cause (histology of the gonads unknown). Altogether, 11 (including 10 novel) polymorphisms in 5'- and 3'-flanking regions of the studied genes were found. The distribution analysis of these polymorphisms showed no association with the DSD phenotypes. Thus, it was concluded that the presence of the causative mutation for testicular or ovotesticular XX DSD in the pericentromeric region of CFA23 is unlikely. © 2014 S. Karger AG, Basel.

    Although the disorder of sex development in dogs with female karyotype (XX DSD) is quite common, its molecular basis is still unclear. Among mutations underlying XX DSD in mammals are duplication of a long sequence upstream of the SOX9 gene (RevSex) and duplication of the SOX9 gene (also observed in dogs). We performed a comparative analysis of 16 XX DSD and 30 control female dogs, using FISH and MLPA approaches. Our study was focused on a region harboring SOX9 and a region orthologous to the human RevSex (CanRevSex), which was located by in silico analysis downstream of SOX9. Two highly polymorphic copy number variable regions (CNVRs): CNVR1 upstream of SOX9 and CNVR2 encompassing CanRevSex were identified. Although none of the detected copy number variants were specific to either affected or control animals, we observed that the average number of copies in CNVR1 was higher in XX DSD. No copy variation of SOX9 was observed. Our extensive studies have excluded duplication of SOX9 as the common cause of XX DSD in analyzed samples. However, it remains possible that the causative mutation is hidden in highly polymorphic CNVR1.

    There is a wide difference of opinion between the medical-surgical community and advocacy group regarding Disorders of Sexual Development (DSD) secondary to congenital adrenal hyperplasia (CAH) being ranked in the intersex category. This rupture is even more evident when the issue of genitoplasty is brought up. For physicians it is obvious and unequivocal that a person with CAH and an XX karyotype has a female gender identity, whereas associations tend to rank persons with CAH in the intersex category and advocate holding-off on surgical management. A retrospective case study vs. control group, spanning over 40years, included 21 patients who were treated in 3 different centers. Each patient and their parents were contacted independently and interviewed regarding interpersonal relationships, psychological impact of genitoplasty, gender identity and opinion on optimal care management for this disorder. Three couples controls (parent-child) per CAH patients were used and matched according to age, sex assigned at birth and ethnic origin. Sex assigned at birth seemed to concord with the gender identity perceived by the patients in 85.7% of cases. In fact, 89.7% of patients and 100% of parents felt that feminizing genitoplasty should be performed within the first year of life. There is however a significant difference compared to controls who felt that surgical management should occur later on in life. No difference was highlighted during childhood regarding parents-child relationships or social integration. However, during adolescence, the parents-child relationship tended to be significantly more painful for the CAH group. Integrating their parenting role was significantly harder for patients in the CAH-DSD group. In the population of CAH-DSD patients who had genitoplasty the level of sexual fulfillment was not lower to the one reported by the control group. Female sex assignment seems legitimate according to this study and the development of gender identity in these

    Radiology was born in 1896 with the immediate recognition of the diagnostic value of X-rays in medicine and progressed throughout the XX Century with the increasing knowledge of its properties and clinical applications. By mid-century Radiology was a respected clinical specialty in advanced countries, the radiological report was a requirement in hospital practice and radiologists' opinions requested in scientific meetings. In the last decades of the century has had a spectacular expansion with the emergence of new imaging modalities and revolutionary technologies that have transformed the specialty worldwide. In Spain Radiology lagged behind needs and demand in 1950. Radiological practice was unregulated and performance of X-ray exams by non-radiologists was common. Teaching of Radiology was non-existent in Medical Schools or postgraduation. The diagnostic value of the specialty was unrecognized by physicians and the role of radiologists ignored. Most hospital radiology services were poorly equipped and functionally inadequate. The shadow of the Civil War (1936-39) was conditioning Radiology in the country. The point of inflexion in the development of Radiology in Spain was the inclusion of film reading sessions in the 1965 academic program of the Society of Radiology. It was in the presentation of cases at these conferences that Clinical Radiology found the finest demonstration ground and as a result was immediately adopted by radiologists and progressively applied in scientific meetings, clinical practices and training programs. Its influence was important in reforming hospital practice, legislation on specialization and education, as well as in national health care plans. At the end of the century radiology in Spain was at a par with the standards of other western nations. The author was a witness of the evolution of Radiology during his 50 years of professional life. This article does not pretend to be exhaustive in names or contributions. It is an overview of

    The present volume contains the lectures and short talks given at the XX International School on Nuclear Physics, Neutron Physics and Applications. The School was held from 16-22 September 2013 in 'Club Hotel Bolero' located in 'Golden Sands' (Zlatni Pyasaci) Resort Complex on the Black Sea coast, near Varna, Bulgaria. The School was organized by the Institute for Nuclear Research and Nuclear Energy of Bulgarian Academy of Sciences. Co-organizer of the School was the Bulgarian Nuclear Regulatory Agency and the Bogoliubov Laboratory of Theoretical Physics of Joint Institute for Nuclear Research - Dubna. Financial support was also provided by the Bulgarian Ministry of Education and Science. According to the long-standing tradition the School has been held every second year since 1973. The School's program has been restructured according to our enlarged new international links and today it is more similar to an international conference than to a classical nuclear physics school. This new image attracts many young scientists and students from around the world. This year, 2013, we had the pleasure to welcome more than sixty distinguished scientists as lecturers. Additionally, twenty young colleagues received the opportunity to present a short contribution. Ninety-four participants altogether enjoyed the scientific presentations and discussions as well as the relaxing atmosphere at the beach and during the pleasant evenings. The program of the School ranged from latest results in fundamental areas such as nuclear structure and reactions to the hot issues of application of nuclear methods, reactor physics and nuclear safety. The main topics have been the following: Nuclear excitations at various energies. Nuclei at high angular moments and temperature. Structure and reactions far from stability. Symmetries and collective phenomena. Methods for lifetime measurements. Astrophysical aspects of nuclear structure. Neutron nuclear physics. Nuclear data. Advanced methods in

    Full Text Available In the article the system of taxation of Orthodox parishes of the Russian Empire in the late XIX — early XX centuries is reconstructed on the new archival materials and the numerous contributions that the parishes carried out from its own funds in favor of the diocesan institutions and charitable organizations are described. Attempt are made to estimate the number of different charges, which existed in this period (the author now includes over 80 items and their size and severity for the parish budget. In this regard, it is concluded that such deductions in some cases accounted for more than half of the income of the parish churches. The author describes the reasons for turning the formally voluntary fees in favor of charitable institutions in virtually compulsory. It investigates the failed attempts of the Supreme Church leadership to reform the system of parish charges in the early XXth century, in particular, the work of the two synodal committees (active in 1905 under the chairmanship of Archbishop Nikon (Sofi yskiy and in 1909, under the chairmanship of Archbishop Anthony (Khrapovitsky. The author comes to the conclusion that these charges were not the only cause of poverty of many parishes (especially rural parishes in Central Russia, but they weakened the parish as a religious community, for the charges were a pretext for permanent discontent among the parishioners about the parish clergy and diocesan authorities. Not the last role here was played by the fact that the diocesan institutions, which were funded by the parish funds were of an estate character.

    Fetal congenital chylothorax is a rare condition that occurs sporadically or can be associated with abnormal karyotype or structural chromosomal anomalies. We report a unique case of fetal congenital bilateral chylothorax associated with mosaicism 47,XXX/46,XX. A female fetus affected by massive bilateral hydrothorax and ascites was diagnosed at 34(+1) weeks of gestation. Previous ultrasonographic exams were completely normal. Immune causes of hydrops were excluded. Elective cesarean section was performed soon after bilateral thoracocentesis. The analysis of drained pleural fluid revealed its lymphatic nature. The fetal karyotyping, performed on chorionic villi at the 11th week, had shown mosaicism 47,XXX/46,XX, later confirmed in the newborn's blood. We hypothesized that chylothorax may be part of the phenotypic spectrum of 47 XXX karyotype and we suggest an ultrasound follow-up of the fetus at closer intervals than the routine timing for this condition, even if it is not usually characterized by severe phenotypic features. © 2013 The Authors.

    Background: In Algeria, the data on infertility and its various causes are rare. Recently, the introduction of assisted reproduction has allowed expecting that 300000 couples, which represent 7% of couples of reproductive age, face difficulty conceiving a child. Knowing that most idiopathic cases are likely to be due to chromosomal abnormalities, we aimed to investigate genetic defects by karyotype analysis in Algerian infertile men, using peripheral blood lymphocytes. Methods: A cytogenetic study was conducted on 10 men from infertile couples by Karyotype analysis of R-banding performed by lymphocyte culture technique. Fluorescence in situ hybridization was performed and molecular abnormalities were investigated by polymerase chain reaction. Follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were evaluated by immunoradiometric method. Results: Chromosomal abnormalities were observed in 30% of the patients. We identified a homogenous Klinefelter syndrome patient with 47, XXY karyotype, a mosaic Klinefelter syndrome patient with 47, XXY/46, XY karyotype and a 46, XX male. Fluorescence in situ hybridization showed that the sex-determining region Y was translocated to the short arm of the X chromosome in patient with 46, XX chromosomal constitution and the presence of the SRY gene was confirmed by polymerase chain reaction and electrophoresis. Conclusion: The occurrence of chromosomal abnormalities in 30% of the infertile men strongly supports the inclusion of routine cytogenetic testing for diagnostic establishment and suitable counseling for couples seeking for assisted reproduction technologies.

    The perception of gender development of individuals with complete androgen insensitivity syndrome (CAIS) as unambiguously female has recently been challenged in both qualitative data and case reports of male gender identity. The aim of the mixed-method study presented was to examine the self-perception of CAIS individuals regarding different aspects of gender and to identify commonalities and differences in comparison with subfertile and infertile XX-chromosomal women with diagnoses of Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) and polycystic ovary syndrome (PCOS). The study sample comprised 11 participants with CAIS, 49 with MRKHS, and 55 with PCOS. Gender identity was assessed by means of a multidimensional instrument, which showed significant differences between the CAIS group and the XX-chromosomal women. Other-than-female gender roles and neither-female-nor-male sexes/genders were reported only by individuals with CAIS. The percentage with a not exclusively androphile sexual orientation was unexceptionally high in the CAIS group compared to the prevalence in "normative" women and the clinical groups. The findings support the assumption made by Meyer-Bahlburg ( 2010 ) that gender outcome in people with CAIS is more variable than generally stated. Parents and professionals should thus be open to courses of gender development other than typically female in individuals with CAIS.

Se han obtenido datos de cuatro fábricas de pianos que funcionaron entre 1830 y principios del siglo XX. Dicha documentación constata que los instrumentos valencianos construidos durante aquel período (1830-1915 obtuvieron gran aceptación tanto en el mercado interno como en el foráneo, y consiguieron prestigiosos galardones en exposiciones y muestras nacionales y extranjeras. También se ha facilitado el conocimiento de los sistemas de producción y comercialización de aquellos talleres, y de las características organológicas que poseyeron los pianos valencianos construidos en las diversas épocas; esa información ha ayudado a valorar la función económica y social que tuvo la fabricación valenciana de pianos en el siglo XIX y ha permitido su comparación con la desarrollada en otras provincias españolas durante la misma época.

    Full Text Available The Cathedral of Vitoria is a building with an extended historical life. We have attempted to produce a chronological sequence of the interventions and architectural “projects” since the beginning of the construction of the church on the early 13th century to the last restorations during the 1960s. This study attempts to fill a void on the available information, crucial for the evaluation of safety and durability issues on the Cathedral. The “anamnesis” practiced on the monument is one of the cornerstones of the method we have chosen for restoration, not only regarding the structural aspects, but regarding the problems of functional interpretation and symbolic content as well. This historical reading the key of structural analysis is what we intend to present: the extraction of the historical building sequence that leads to the current situation of the building, discriminating the different moments of the architectural project, phases of building growth and repair interventions on the structure that comment on or contradict among themselves, to result in the form that we witness now. We use that sequence to evaluate, albeit partially, the safety status of the structure, and to build a working hypothesis for the structural aspects of the restoration tasks.La Catedral de Vitoria es un edificio con una larga vida histórica, llena de acontecimientos constructivos que han venido interesando su comportamiento como estructura construida.

The kinetic study was carried out by gravimetric measurements. The nature of corrosion products was analysed by low angle XRD and Scanning Electron Microscopy (SEM). The corrosion is due to nucleation and growth of Al{sub 2}O{sub 3}-3H{sub 2}O on the material surface. The corrosion increases with the reinforcement proportion, chloride concentration and copper content. (Author) 10 refs.

    In humans, Desert Hedgehog (DHH) gene mutations are a very rare cause of 46,XY gonadal dysgenesis (GD), eventually associated with peripheral neuropathy. Clinical records of 12 patients with 46,XY GD and unknown genetic background were reviewed and a 46,XY woman with peripheral neuropathy was individuated. Her 46,XX sister affected by similar neuropathy was also investigated. Genomic DNA was extracted and DHH exons sequenced and analyzed. A comparative genomic hybridization array was also performed. In both the 46,XY and 46,XX sisters, a homozygous c.554C>A mutation in exon 2 of the DHH gene was found, determining a premature termination codon (p.Ser 185*). Heterozygous consanguineous carrier parents showed neither reproductive problems nor peripheral neuropathy. In the proband and her sister, a 499-kb duplication in 9p22.1 was also found. A 46,XY European woman with 46,XY GD and a novel homozygous DHH pathogenic variant is reported, confirming that this gene plays a key role in male gonadal development. Her 46,XX sister, harboring the same mutation, showed normal internal and external female phenotype. Thus, DHH seems not to be involved in the ovarian development pathway or its postpubertal function. Homozygous DHH mutations cause a specific peripheral neuropathy in humans with both 46,XY and 46,XX karyotypes. © 2018 S. Karger AG, Basel.

    Full Text Available In the first decades of the XX century the possibility of a particular newspaper having a high number of subscribers was, from the point of view of the newspaper publishers, the best guarantee of its stability. However it was not all advantages in a system which gave rise to numerous complaints and created a peculiar relationship with the subscriber. By various means —delivery men, the post and public establishments, principally— the subscription service continually generated situations illustrative of the level of development of the Spanish press in years in which progress accelerates and deficiencies and limitations also become apparent. Limitations which, particularly in an outlying region with mostly inadequate means of communication such as Asturias, could become one of the main factors delaying the establishment of a large press with mass-readership.

Tal literatura possui duas vertentes a monarquista e a republicana, ambas advogando medidas de reestruturação da Marinha. Por outro lado, o trabalho analisa ainda as medidas efetivamente tomadas ou não pelos sucessivos governos republicanos, até o ano de 1910, com o objetivo de promover as reformas necessárias à adequação da Marinha aos novos tempos, novas tecnologias e novas sociabilidades. O fim da escravidão, a Revolta da Armada, a corrida armamentista internacional e a que terminou por se estabelecer entre o Chile, a Argentina e o Brasil, na América do Sul, permitem compreender tanto as propostas aventadas como os limites das reformas encetadas.

    Full Text Available A través de este artículo se ha intentado dar una explicación —dentro del contexto español— al tradicional vínculo entre republicanismo, anticlericalismo y masonería. Para ello hemos recurrido a analizar la trayectoria de un hombre público, Carlos Esplá, que responde plenamente al perfil esencial del republicano del primer tercio del siglo XX. Se ha querido, otra cosa es que se haya conseguido, demostrar como en muchos casos tal vinculación no respondía tanto a cuestiones dogmáticas, como a motivaciones racionalistas o coyunturales. Es decir, buena parte de los republicanos eran anticlericales y masones, lo que no quería decir que fuesen antirreligiosos, ni tampoco que cumpliesen con los ritos y las consignas del Grande Oriente. Ambas militancias estaban estrechamente ligadas a una coyuntura histórica específica.Through this article we have tried to explain —within the spanish context— the traditional link between republicanism, anticlericalism and masonry. For that reason we have resorted to analise he career of a republic man, Carlos Esplá, who perfectly answers to the profile of the republican of the first third of the xx Century. We have, we don't know if we have succeeded, to show how in lots of cases such a connection doesn't have to do with dogmatic questions as much as rationalistic or current motives. A great idea of republicans were anticlerical and masons, which didn't mean they were anti-religious, ñor that they followed the rites and instructions of the Great East. Both affiliations/tendencies were closely linked to a specific historical situation.

    Full Text Available Este artículo muestra de manera general la gran importancia de la fenomenología como un paradigma teórico clave, porque influyó de manera contundente en la ciencia y la filosofía del siglo xx. Su influencia se deja ver en los autores más conspicuos del existencialismo, del historicismo, de la hermenéutica, de la historia de la ciencia, de la filosofía analítica, de la llamada postmodernidad; su ascendiente es notable en personajes importantes de las místicas y las religiones contemporáneas. Aquí se señala también el surgimiento y la influencia de la fenomenología en pensadores mexicanos de mediados del siglo xx. Como filosofía, se opone al positivismo y a lo que Husserl llamó el "objetivismo", se muestra cómo la fenomenología reivindica la perspectiva del sujeto y se opone a la falta de voluntad y de método de diversas escuelas para esclarecer la intencionalidad. Se introduce a nociones básicas de esta corriente como son: "fenomenología trascendental", la perspectiva del sujeto, "reducción fenomenológica", "acto intencional" y "objeto intencional", "lo constituido" y "lo constituyente", para terminar con la presentación de lo que Husserl define como "psicología fenomenológica", que es un camino al autoconocimiento del individuo y la sociedad.

  19. Design of a QA method to characterize submillimeter-sized PBS beam properties using a 2D ionization chamber array

    Pencil beam scanning (PBS) periodic quality assurance (QA) programs ensure the beam delivered to patients is within technical specifications. Two critical specifications for PBS delivery are the beam width and position. The aim of this study is to investigate whether a 2D ionization chamber array, such as the MatriXX detector (IBA Dosimetry, Schwarzenbruck, Germany), can be used to characterize submillimeter-sized PBS beam properties. The motivation is to use standard equipment, which may have pixel spacing coarser than the pencil beam size, and simplify QA workflow. The MatriXX pixels are cylindrical in shape with 4.5 mm diameter and are spaced 7.62 mm from center to center. Two major effects limit the ability of using the MatriXX to measure the spot position and width accurately. The first effect is that too few pixels sample the Gaussian shaped pencil beam profile and the second effect is volume averaging of the Gaussian profile over the pixel sensitive volumes. We designed a method that overcomes both limitations and hence enables the use of the MatriXX to characterize sub-millimeter-sized PBS beam properties. This method uses a cross-like irradiation pattern that is designed to increase the number of sampling data points and a modified Gaussian fitting technique to correct for volume averaging effects. Detector signals were calculated in this study and random noise and setup errors were added to simulate measured data. With the techniques developed in this work, the MatriXX detector can be used to characterize the position and width of sub-millimeter, σ  =  0.7 mm, sized pencil beams with uncertainty better than 3% relative to σ. With the irradiation only covering 60% of the MatriXX, the position and width of σ  =  0.9 mm sized pencil beams can be determined with uncertainty better than 3% relative to σ. If one were to not use a cross-like irradiation pattern, then the position and width of σ  =  3.6 mm sized pencil beams

    The Caspian Sea - the unique largest enclosed inland body of water on Earth. Significant periodic sea level fluctuations are a typical feature of the sea. In the XIX-XX centuries a number of comprehensive studies of the Caspian Sea was carried out. The results are published in the papers, monographs and climatic atlases. But a number of fundamental questions about the features of the hydrological regime of the Caspian Sea is still open: 1. How does the water circulation change during the level variations? 2. What is the effect of heterogeneity of evaporation from the water surface on the formation of the flow field in the conditions of long-term level changes? 3. How does the water salinity regime change depending on the sea level position, water circulation, river flow and different climatic influences? 4. What is the effect of extreme events (multi-hazards) (ice, storms, destruction of the coasts) on coastal infrastructure? In 2016, the project aims to study hydrological regime extreme effects of the Caspian Sea was supported by the Russian Foundation for Basic Research. Within this project all of the above problems will be solved. Geographic information system "Caspian Sea" for the storage and data processing, including a database of primary oceanographic information for the period of instrumental observations (1897-2013), cartographic database (1921-2011) and tools for multidimensional analysis of spatio-temporal information is the basis of the study. The scheme of interconnected hydrodynamic models (Caspian Sea MODel - Ocean Model - Wind wave model) was developed. The important factors are taken into account in the structure of the models: long-term and seasonal dynamics of the sea waves parameters, new long-term values of evaporation from the shallow waters areas of the Caspian Sea, water circulation. Schemes of general seasonal circulation of the Caspian Sea and the Northern Caspian at different positions of the sea level in XX-XXI centuries using

    Full Text Available Problem Setting. The article describes the activities of the zemstvo self-government which had a significant impact on the process of national constitutionalism development in the late XIX – early XX centuries. The actuality of the topic. Zemstvo self-government got significant practical experience of legal oppositional activity, which is an important element of constitutionalism. Within the territory of ethnicUkraine, zemstvo constitutionalism combined two components: All-Russian and national. The purpose of the article. All-Russian zemstvo constitutionalism had features of legal, semi-legal and illegal activities, which were represented by liberal and radical wing of zemstvo liberal-democratic movement respectively. In the All-Russian context, zemstvo radicals advocated the idea of establishing constitutional order in the Russian Empire, which involved constitutional recognition of democratic rights and freedoms, equality, parliamentary system and establishment of a constitutional monarchy, decentralization of power, political pluralism. The national component of zemstvo constitutionalism, which was formed at the beginning of the bourgeois-democratic revolution of 1905–1907, had illegal character and its essence can be described by the fact that some zemstvo liberals insisted on the need to restore the Ukrainian state in the form of autonomy within democratic Russia. Representatives of both components of zemstvo constitutionalism aimed to implement their constitutional ideas through reforms. Zemstvo constitutionalism reached its highest peak at the beginning of the bourgeois-democratic revolution of 1905–1907. In early XX century zemstvo liberals took active part in activities of bourgeois-democratic political parties. Development of Russian and Ukrainian political parties led to a split in the radical wing of zemstvo liberal-democratic movement on the national basis. Some zemstvo leaders joined the All-Russian Party of Octobrists and

    46,XX testicular disorder of sex development is a rare genetic syndrome, characterized by a complete or partial mismatch between genetic sex and phenotypic sex, which results in infertility because of the absence of the azoospermia factor region in the long arm of Y chromosome. We report a case of a 14-year-old male with microorchidism and mild bilateral gynecomastia who referred to our hospital because of abnormal gender characteristics. The patient was treated for congenital scrotal type hypospadias at the age of 4 years. Semen analysis indicated azoospermia by centrifugation of ejaculate. Levels of follicle-stimulating hormone and luteinizing hormone were elevated, while that of testosterone was low and those of estradiol and prolactin were normal. The results of gonadal biopsy showed hyalinization of the seminiferous tubules, but there was no evidence of spermatogenic cells. Karyotype analysis of the patient confirmed 46,XX karyotype and fluorescent in situ hybridization analysis of the sex-determining region Y (SRY) gene was negative. Molecular analysis revealed that the SRY gene and the AZFa, AZFb and AZFc regions were absent. No mutation was detected in the coding region and exon/intron boundaries of the RSPO1, DAX1, SOX9, SOX3, SOX10, ROCK1, and DMRT genes, and no copy number variation in the whole genome sequence was found. This study adds a new case of SRY-negative 46,XX testicular disorder of sex development and further verifies the view that the absence of major regions from the Y chromosome leads to an incomplete masculine phenotype, abnormal hormone levels and infertility. To date, the mechanisms for induction of testicular tissue in 46,XX SRY-negative patients remain unknown, although other genetic or environmental factors play a significant role in the regulation of sex determination and differentiation.

    SOX9 mutations cause the skeletal malformation syndrome campomelic dysplasia in combination with XY sex reversal. Studies in mice indicate that SOX9 acts as a testis-inducing transcription factor downstream of SRY, triggering Sertoli cell and testis differentiation. An SRY-dependent testis-specific enhancer for Sox9 has been identified only in mice. A previous study has implicated copy number variations (CNVs) of a 78 kb region 517-595 kb upstream of SOX9 in the aetiology of both 46,XY and 46,XX disorders of sex development (DSD). We wanted to better define this region for both disorders. By CNV analysis, we identified SOX9 upstream duplications in three cases of SRY-negative 46,XX DSD, which together with previously reported duplications define a 68 kb region, 516-584 kb upstream of SOX9, designated XXSR (XX sex reversal region). More importantly, we identified heterozygous deletions in four families with SRY-positive 46,XY DSD without skeletal phenotype, which define a 32.5 kb interval 607.1-639.6 kb upstream of SOX9, designated XY sex reversal region (XYSR). To localise the suspected testis-specific enhancer, XYSR subfragments were tested in cell transfection and transgenic experiments. While transgenic experiments remained inconclusive, a 1.9 kb SRY-responsive subfragment drove expression specifically in Sertoli-like cells. Our results indicate that isolated 46,XY and 46,XX DSD can be assigned to two separate regulatory regions, XYSR and XXSR, far upstream of SOX9. The 1.9 kb SRY-responsive subfragment from the XYSR might constitute the core of the Sertoli-cell enhancer of human SOX9, representing the so far missing link in the genetic cascade of male sex determination.

    To characterize molecular and cytogenetic abnormalities in six 46, XX males, and to investigate the clinical manifestations and underlying mechanisms in such patients. Clinical data of six XX male patients were collected. Karyotyping, multiple polymerase chain reaction (PCR) and fluorescence in situ hybridization (FISH) were utilized to detect and locate the sex determining region (SRY) gene. PCR and FISH showed that all patients were SRY-positive XX males. All patients have their SRY gene located at the tip of derivative X chromosomes, which have resulted from translocation between short arms of X and Y chromosomes. High resolution karyotyping at 550-750 band level has revealed that the translocation breakpoints were at Xp22.33 and Yp11.2 in three patients. In the remaining patients, the breakpoints were either at Xp22.32 and Yp11.31 or Xp22.31 and Yp11.2. The breakpoints at Xp22.32, Xp22.31 and Yp11.31 were rarely reported. Genotype-phenotype correlation analysis indicated that the clinical manifestations were age-specific. Four adult patients have come to clinical attention due to infertility, with typical features including azoospermia and testis dysgenesis, whereas poorly developed secondary sexual characteristics and short stature were main complaints of adolescence patients, and short stature was the sole symptom in a child patient. Combined karyotyping, PCR and FISH are important for the analysis of XX males. Particularly, high resolution karyotyping is valuable for the refinement of chromosome breakpoints and detailed analysis of genotype-phenotype correlation.

    We report four patients with SRY-positive 46,XX testicular disorders of sex development (46,XX-TDSD) (cases 1-4). Case 1 exhibited underdeveloped external genitalia with hypospadias, case 2 manifested micropenis and cases 3 and 4 showed normal external genitalia. The Xp;Yp translocations occurred between the X- and the Y-differential regions in case 1, between PRKX and inverted PRKY in case 2 and between the X-chromosomal short arm pseudoautosomal region and the Y-differential regions in cases 3 and 4. The distance of the Yp breakpoint from SRY was ~0.75 Mb in case 1, ~6.5 Mb in case 2, ~2.3 Mb in case 3 and ~72 kb in case 4. The Xp;Yp translocation occurred within an 87-bp homologous segment of PRKX and PRKY in case 2, and between non-homologous regions with addition of an 18-bp sequence of unknown origin in case 4. X-inactivation analysis revealed random inactivation in cases 1-4. The results argue against the notion that undermasculinization in 46,XX-TDSD is prone to occur when translocated Yp materials are small (<100 kb of the Y-differential region), and imply that the Xp;Yp translocations result from several mechanisms including non-allelic homologous recombination and non-homologous end joining.

  15. Review of Outcome Information in 46,XX Patients with Congenital Adrenal Hyperplasia Assigned/Reared Male: What Does It Say about Gender Assignment?

    Full Text Available There is ample historical verification of 46,XX congenital adrenal hyperplasia (CAH patients being born with essentially male genitaliawhile outcome information is scant. Prior to glucocorticoid therapy, most patients died very young from adrenal insufficiency. Most available reports from laterchildhood, contain little information concerning sexual identity. Reports on older individuals lack adequate information about sexual identity and quality of life. The difficulty in assessing the relative impact of multiple dynamic environmental factors on the development of sexual identity, self- and body esteem and overall adjustment to life is clear. Nevertheless, it remains unclear whether those infants whose masculine genitalia at birth resulted in an initial male assignment would have enjoyed a better adult outcome had they been allowed to remain male rather than the female reassignment that most received. Further, one could ask whether a male sex of rearing should be considered in 46,XX CAH infants with male external genitalia. After reviewing available literature, we conclude that because those extremely virlized 46,XX CAH patients who were reared male with healthy social support demonstrated satisfactory levels of social and sexual function as adults a male sex assignment should be considered in these types of infants when social and cultural environment are supportive.

    2016-06-01

    Full Text Available Este artículo analiza la trayectoria de políticas coercitivas con las que el Estado argentino intentó inferir en la producción de sexualidades durante el siglo XX. La “violencia moral” incluyó prácticas de represión: códigos de faltas provinciales y razzias como formas de delimitación a homosexuales, prostitutas y pobres urbanos. Las mismas constituyeron un hilo de continuidad entre gobiernos civiles y regímenes castrenses. La premisa sostiene que ante la percepción de precarización de una identidad de la cultura nacional oficial, promovida por cambios sociales, demográficos, económicos y culturales en los albores del siglo, el Estado actuó progresivamente como catalizador de la reproducción directa de relaciones dominantes. La sensación de fragilidad de las condiciones que hacían perdurable una ciudadanía imaginada como heterosexual, blanca, masculina y capitalista se institucionalizó en un modo de concebir la moral que devino en políticas violentas. Partiendo de esta hipótesis se analizaran las formas especificas que asumieron estas políticas en el territorio urbano bonaerense. Con el fin de problematizar el vínculo entre Estado, sexualidades y violencias.

    Full Text Available During the early decades of the 20th century, the Spanish socio-sanitary situation was described as catastrophic, both in the urban as well as in the rural setting. In that context, sanitation emerged as one of the key elements of the regeneration process taken on by hygiene in its role as mediator. Through the works of hygienists G. de Membrillera and Luis Muñoz Antuñano, published in 1921, we have approached the analysis of the sanitary situation of rural Spain during this period.

    Mouse sex determination provides an attractive model to study how regulatory genetic networks and signaling pathways control cell specification and cell fate decisions. This study characterizes in detail the essential role played by the insulin receptor (INSR) and the IGF type I receptor (IGF1R) in adrenogenital development and primary sex determination. Constitutive ablation of insulin/IGF signaling pathway led to reduced proliferation rate of somatic progenitor cells in both XX and XY gonads prior to sex determination together with the downregulation of hundreds of genes associated with the adrenal, testicular, and ovarian genetic programs. These findings indicate that prior to sex determination somatic progenitors in Insr;Igf1r mutant gonads are not lineage primed and thus incapable of upregulating/repressing the male and female genetic programs required for cell fate restriction. In consequence, embryos lacking functional insulin/IGF signaling exhibit (i) complete agenesis of the adrenal cortex, (ii) embryonic XY gonadal sex reversal, with a delay of Sry upregulation and the subsequent failure of the testicular genetic program, and (iii) a delay in ovarian differentiation so that Insr;Igf1r mutant gonads, irrespective of genetic sex, remained in an extended undifferentiated state, before the ovarian differentiation program ultimately is initiated at around E16.5.

    We report on an adult male initially presenting with gynecomastia and a painless scrotal mass without additional genital anomalies. Hyperpigmentation of the skin following the Blaschko's lines was identified. He underwent gonadectomy because of suspected cancer. Histological analyses revealed an ovotestis with ovulatory activity confirmed by immunohistochemistry with multiple markers. Karyotyping of cultured peripheral blood lymphocytes and a buccal smear revealed a 46,XX/46,XY chimeric constitution with different percentages. Multiple molecular analyses as well as blood typing implied a tetragametic origin. After the unilateral gonadectomy, the patient developed recurrent painful cystic swellings of the remaining gonad. Because of the wish to preserve hormonal activity as well as future fertility, the patient underwent surgical resection of a cystic gonadal area. The removed tissue showed ovulation-related features in addition to both testicular and ovarian tissue, diagnosed as an ovotestis. Testosterone therapy was initiated to suppress the persistently elevated gonadotropins and thereby suppress ovarian activity. During treatment, the recurrent pain complaints and cystic swellings ceased, although gonadotropin levels were not fully suppressed. Based on these observations, the importance of a detailed genetic and pathological diagnosis and the clinical dilemmas including the pros and cons of personalized treatment with gonadal preservative surgery are discussed. © 2017 S.

    The influence of silicon carbide particles (SiCp) proportion and matrix composition of aluminium metal matrix composites (A3xx.x/SiCp) modified by lanthanum-based conversion or electrolysis coating was evaluated in 3.5 wt% NaCl aerated solution. The intermetallic compounds were preferentially covered by lanthanum-based conversion coatings obtained by immersion in 50 deg. C solution of La(III) salt, and the intermetallic compounds, SiCp and aluminium matrix were covered by lanthanum electrolysis treatment. The corrosion process was studied on the basis of gravimetric tests and electrochemical impedance spectroscopy (EIS) during immersion in 3.5 wt% NaCl aerated solution. The composition of both La coating and corrosion products was analyzed before and after accelerated testing, by scanning electron microscopy (SEM), atomic force microscopy (AFM), low-angle X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) to determine the influence of surface microstructural changes on corrosion behaviour during exposure to the corrosive environment. The corrosion process was more influenced by the concentration of alloy elements in the matrix than by the proportion of SiCp reinforcement. Both lanthanum treated surfaces presented better behaviour to chloride solution corrosion than original composite surfaces without treatment; however, electrolysis afforded a higher degree of protection than the conversion treatment because the coating was more extensive

    We investigate how thermal quantum discord (QD) and classical correlations (CC) of a two-qubit one-dimensional XX Heisenberg chain in thermal equilibrium depend on the temperature of the bath as well as on nonuniform external magnetic fields applied to two qubits and varied separately. We show that the behavior of QD differs in many unexpected ways from the thermal entanglement (EOF). For the nonuniform case (B{sub 1} = -B{sub 2}), we find that QD and CC are equal for all values of (B{sub 1} = -B{sub 2}) and for different temperatures. We show that, in this case, the thermal states of the system belong to a class of mixed states and satisfy certain conditions under which QD and CC are equal. The specification of this class and the corresponding conditions are completely general and apply to any quantum system in a state in this class satisfying these conditions. We further find that the relative contributions of QD and CC can be controlled easily by changing the relative magnitudes of B{sub 1} and B{sub 2}. Finally, we connect our results with the monogamy relations between the EOF, CC and the QD of two qubits and the environment.

    Savage, B.D.

    1975-01-01

    Interstellar extinction curves over the wavelength region 1800--3600 A are presented for 36 stars. The stars have E (B-V) in the range 0.03 to 0.55, and are mostly confined to the brighter OB associations distributed along the plane of the Galaxy. Every extinction curve exhibits a broad extinction bump peaking near 2175 A (4.6 μ -1 ). The position of the peak and the profile of the feature appear remarkably constant among the sample of stars. With only a few exceptions, E (lambda)-3320, a measure of the strength of the feature, correlates very well with E (B-V), implying that the bump has an interstellar rather than a circumstellar origin. The observation that the bump position and shape are constant, or very nearly constant, places severe restrictions on the grain geometrical parameters if the feature is to be explained by classical scattering theory employing bulk optical constants. In fact, the restrictions are so severe that an alternate explanation seems to be required unless the dust grains that exist in widely separated regions of space and under very different physical conditions have nearly identical size and shape distributions. Three extinction curves that extend to 1100 A are also presented. These curves show the same general extinction characteristics reported earlier. The curve for 22 Sco provides another example of a star that is []physically associated with nebulosity and that also has abnormally low far-ultraviolet extinction. We have searched the extinction curves for fine structure such as abrupt slope changes or new diffuse interstellar features. Unfortunately, there is no convincing evidence for such structure over the interval 1800--3600 A. (auth)

Partimos da hipótese de que a postura do relator fazia parte de uma extensa ação disciplinadora de controle da cidade, à qual a imprensa não escapava. Tal ação disciplinadora estava pautada pelas teorias racistas e deterministas de matriz européia e articulava diversas instâncias do poder. Aplicadas de modo particular ao contexto brasileiro em razão do passado escravista, a tentativa de ordenamento da cidade agrega o racismo de cor ao de classe, redimensionado no novo contexto republicano.This article is about representations of the city of São Paulo made by the periodical O Estado de S. Paulo in 1910 and analyses a case of censorship towards the media, through a Report of Justice, related to the divulgation of fait divers style suicide cases in the period of transition between the 19th and the 20th centuries. We start from the following hypothesis: the position of the author of the Report was influenced by an extensive disciplinary action set up to control the city and that targeted also the media. Such disciplinary action was based on racist and determinist theories, of european matrix, and articulated various levels of power. Applied to this particular Brazilian context due to its legacy of slavery, the attempt to put order in the city joins the racism to social exclusion, adapted to the New Republican era.

It is shown that high moral ideals and a desire to help people in need be useful to its edge and to society in general – describe the ideas, common in the student's environment at the turn of XIX – XX centuries. Based on the analysis of archival materials and scientific literature, it was found that the students showed during this period, an increased desire to participate in social and cultural life of Siberia and the whole country. However, this participation in different ways manifested in the minds and actions of young people. Some students, actively engage in the cultural life of the region, entered in the companies involved in charity work, academic research, literary and theatrical art, medicine, advanced study of philosophy, technical processes, etc. At universities created various thematic interest groups, on a territorial basis – numerous fraternities, a nobility of purpose in the form of moral and material support of their members. However, some Siberian students in their own way understood his own mission in social processes, including under the form of participation in legal societies, clubs or fraternities in the activities of political and campaign focus, in the meetings discussing ideas about the possibilities of revolution, as expected, from their point of view, progress and prosperity in case of their implementation. Also in this period, there are illegal organizations that engage some students of Siberian universities. The activities of such organizations is highly political in nature.

    Full Text Available La sociedad salteña, a principios del siglo XX, se caracterizaba por importantes desigualdades de tipo social, que a su vez cristalizaban en problemas en el ámbito de la salud y la educación. Con tasas de mortalidad general e infantil muy altas, ocasionadas por el impacto de dolencias endémicas y epidémicas, la población debía lidiar con graves problemas de salud. No obstante, en 1919 esa situación se agravó, a las epidemias y endemias se sumó la segunda oleada de la pandemia de “gripe española” generando una crisis de mortalidad. En este artículo se pretende analizar el papel  que habría tenido  la segunda oleada de gripe española en la provincia y en los Departamentos de la misma que habría generado esta crisis. Para ello se realiza un análisis de carácter cuantitativo con base a datos provistos por la Dirección de Estadísticas de la Provincia de Salta (Argentina, con los cuales se generarán tasas de mortalidad y sobremortalidad que se relacionarán con datos provistos por el censo de población de 1914 proyectados, este análisis será relacionado con datos cualitativos que provee el único  periódico de la época encontrado.

    Full Text Available El objetivo de este trabajo es establecer cuáles eran los beneficios sociales otorgados por los propietarios de ingenios en sus fábricas y qué relación tenían estos beneficios con las concepciones que tenían los industriales en torno a la “cuestión social” en un período que se extiende desde fines del siglo XIX hasta principios del siglo XX. La actividad azucarera demostró tempranamente la necesidad de contar con una mano de obra disciplinada y para lograrlo fue importante el respaldo de los poderes públicos a través del diseño de un marco legal que respaldaba las estrategias desplegadas por las fábricas y cañeros para asegurar ese objetivo. A la par de esta legislación coercitiva, los industriales tucumanos otorgaban también una serie de beneficios como vivienda, seguros, asistencia médica primaria y educación. Es decir, que desde temprano las prácticas coactivas se combinaron con asistencialismo, y resulta de interés ofrecer alguna clave explicativa del sentido de estas acciones. Las diferencias existentes entre los ingenios, se traducían en marcadas desigualdades en los beneficios que recibían los trabajadores, pero sin duda era la pertenencia a la fábrica en calidad de trabajador lo que aseguraba la vivienda, la ración y la atención médica y por lo tanto pérdida del puesto laboral no sólo implicaba la pérdida del salario sino también del lugar de residencia y el acceso a los beneficios.

    Full Text Available Los ejércitos de Seti y de Ramses II que lucharon contra los hititas estaban en posesión de la mayoría de las armas más modernas de su época. Las tropas egipcias dependían de los carros y de la infantería que esencialmente luchaba con hachas, espadas cortas, espadas de hoz, jabalinas, mazas, venablos, hondas y se defendían con escudos. El uso de cascos, cotas de placas de bronce se extendió con rapidez y los mercenarios shardana introdujeron las espadas largas. Con la crisis política a finales de la dinastía XIX, y la pérdida de territorios a inicios de la dinastía del XX, el ejército perdió también parte de sus recursos y los artesanos asiáticos especializados en la metalurgia.The army of Seti I and Ramses II, which fought against the hittites, possessed the most modem weapons of that era. The Egyptian troops depended upon chariots and infantry which essentially fought with axes, short swords, sickle swords, spears, javelins, lances, self and composite bows and who defended themselves with shields. The use of helmets and coats of mail became more and more widespread and the shardana mercenaries introduced long swords. With the political crisis at the end of the XIXth. Dynasty and the loss of territory at the beginning of the XXth. Dynasty, the army lost its arms resources, which come from Asian towns specialized in metallurgy.

    One of the most important problems in designing an experiment or a survey is sample size determination and this book presents the currently available methodology. It includes both random sampling from standard probability distributions and from finite populations. Also discussed is sample size determination for estimating parameters in a Bayesian setting by considering the posterior distribution of the parameter and specifying the necessary requirements. The determination of the sample size is considered for ranking and selection problems as well as for the design of clinical trials. Appropria

    The scale dependence in firm growth (smaller firms grow faster) is systematically reflected in the size distribution. This paper studies whether taxes affect the equilibrium firm size distribution in a cross-country context. The main finding is that the empirical association between firm growth and corporate tax (VAT) is positive (negative), with notable differences in the response of manufacturing firms and that of the others. We draw implications for recent debate on the impact of taxes and...

In addition, we propose comprehensive clinical guidelines in the management of this condition to aid fertility clinicians in their management of affected individuals. Case report with expert consensus-derived clinical management guidance. Fertility outpatient clinic at a tertiary referral center. A 40-year-old male found to have 46,XX disorder of sex development (DSD) on routine fertility screening. A review of the literature, expert consultation, and formulation of comprehensive clinical guidance. We report an interesting and rare case of a phenotypical male with the karyotype 46,XX DSD without an SRY region. There is limited literature exploring this condition, and its etiology remains poorly understood. There is currently no clinical guidance available for fertility clinicians to follow when treating this condition. A male phenotype with a 46 karyotype without the sex-defining region of the Y chromosome. A multidisciplinary approach should be adopted in the management of 46,XX individuals. All patients with azoospermia must be karyotyped. Sperm donation remains the only fertility treatment available. The 46,XX patients need lifelong followup led by an endocrinologist with regular imaging of the gonads, bone density measurements, baseline blood tests, and T supplementation. Psychological support is a key part of a holistic approach. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

Special attention is given to the most peculiar aspects of this chase, such as its legislation, the massive killing of dolphins in Pontevedra, or the chasing runs by navy patrolboats in the river estuaries of Galicia. Finally, after mentioning the attempts at establishing a dolphin industry in the 18th and 19thcenturies, a study is made of the most ambitious plan undertaken in the 20th century to secure the involvement of the whaling industry into this activity. The study also refers to the situation of this activity in the rest of Spain both for its direct relationship with and as a precedent for the Galician case, and makes a comparison between them.

In addition, images are classified according to the nationalist point of view of the «people.» The copy of previous images, mostly photographic ones, communicates a sense of realism and truth which appears well reflected in both in the material elements and the gestures using them. This fact does not prevent the ideological interpretation of the images. The choice of scene themes intends to reflect the existing regional diversity starting from an ideological selection. The data collected shows the prevalence of some aspects and puts special emphases on vine issues and, particularly, on grape harvest. Other issues represented include the olive harvest, activities related to cereals, the collection of seaweed for field manuring. Less represented are scenes of markets.Este trabajo ofrece una aproximación parcial al variado contenido de los paneles de azulejos portugueses de la primera mitad del siglo XX que se encuentran en una amplia gama de edificios: estaciones de tren, mercados, plazas, fuentes, comercios, casas particulares, etc. En ellos, las imágenes de los campesinos aparecen filtradas por la óptica de las élites y están categorizadas por la interpretación nacionalista del «pueblo».

Francia y su especial influjo en aspectos políticos y administrativos proporciona los principios que atraen a muchos protagonistas de la educación española durante el primer tercio del XX; Alemania, junto a la sistematización de su pensamiento ofrece una pedagogía propiciadora de un socialismo humanista y una ética nueva; el modelo de formación de minorías que caracteriza la pedagogía inglesa fascina a liberales y conservadores. La influencia de la Rusia soviética es visible sobre todo durante la República en guerra, un momento éste en el que, y hasta mediados del siglo, la educación del régimen de Franco conoce también el peso de la pedagogía nazi sobre todo en la organización de la juventud y en experiencias de asistencia social, y de la pedagogía del fascismo italiano en la política educativa del primer franquismo. A partir de entonces la influencia en la política educativa española corresponde a los organismos internacionales.ABSTRACT: The influence European macro models have upon Spanish educational policy, is studied in this article. France and its special influence in political and administrative aspects, provides the principles which attract many protagonists of the Spanish education during the first third of the 20th century. Germany, with the systematisation of its thoughts, offers a pedagogy that propitiates a humanist socialism and a new ethic. The model of education of minorities, characteristic of English pedagogy, fascinates both liberals and conservatives. The influence of the Soviet Russia is visible above all during the Republic in times of the Civil War, moment in which, and until about the middle of the 20th century, Franco’s regime education also knows the weight of nazi pedagogy, specially in youth organisations and in social work experiences, and the Italian’s fascism

In general, most of the housing stock of Ukraine is in a poor technical condition due to its deficient funding; it keeps the tendency of premature aging of the housing stock.One of the major problems of modern construction industry is the continuation of housing exploitation, in particular is it the building era of mass construction of 50-60-ies of XX century, called "Khrushchevki".

    Full Text Available Los personajes masculinos fueron los protagonistas principales de Marvel Comics durante el siglo XX. Dichos personajes mostraban algunas características de forma persistente que ayudaron a fraguar un mito de la masculinidad. A pesar de esto, dicho mito evolucionó a partir de 1961, ampliando los estrechos márgenes de la masculinidad. Los objetivos de este artículo son, en primer lugar, entender cuál fue el mensaje que lanzaba dicho mito, cómo afectaba a los hombres en función de si eran jóvenes, adultos o ancianos, y en qué modo cambió con el paso del tiempo. En segundo lugar, nos proponemos entender las transformaciones sociales, económicas y productivas que ayudaron a desarrollar un nuevo mito de la masculinidad. Para lograr esto, vamos a estudiar algo más de un centenar de publicaciones de Marvel Comics publicadas entre los años 1940 y 2000, analizando desde la perspectiva de los Estudios Culturales los arquetipos presentados. Entre las conclusiones a las que hemos llegado cabe destacar la existencia de un modelo patriarcal de masculinidad que sobrevivió sin problemas hasta 1960 debido a una mezcla de factores políticos, económicos y productivos, si bien los importantes cambios en la producción de cómics experimentada en las oficinas de Marvel durante 1961 condujeron a que dicho modelo dejase de ser el único existente; a esto ayudaron en los años sesenta y setenta los importantes problemas políticos, económicos y sociales que sacudieron los Estados Unidos. A pesar de todo ello, no podemos afirmar que el mito de la masculinidad evolucionara de una manera irreversible e imparable, antes al contrario, existió una relación dialéctica entre un nuevo y un viejo mito de masculinidad.

    The purpose of this study is to explain fluctuations in email size. We have previously investigated the long-term correlations between email send requests and data flow in the system log of the primary staff email server at a university campus, finding that email size frequency follows a power-law distribution with two inflection points, and that the power-law property weakens the correlation of the data flow. However, the mechanism underlying this fluctuation is not completely understood. We collected new log data from both staff and students over six academic years and analyzed the frequency distribution thereof, focusing on the type of content contained in the emails. Furthermore, we obtained permission to collect "Content-Type" log data from the email headers. We therefore collected the staff log data from May 1, 2015 to July 31, 2015, creating two subdistributions. In this paper, we propose a model to explain these subdistributions, which follow log-normal-like distributions. In the log-normal-like model, email senders -consciously or unconsciously- regulate the size of new email sentences according to a normal distribution. The fitting of the model is acceptable for these subdistributions, and the model demonstrates power-law properties for large email sizes. An analysis of the length of new email sentences would be required for further discussion of our model; however, to protect user privacy at the participating organization, we left this analysis for future work. This study provides new knowledge on the properties of email sizes, and our model is expected to contribute to the decision on whether to establish upper size limits in the design of email services.

The territory is chosen by the authors is very important for creation of the project of ideal administrative-territorial structure of government and its embodiment in reality in terms transborder area, geostrategic position and recognition of military and economic importance of the region. The authors were able to create governance models in accordance with the phased tasks of the development of the territory, as well as fill some gaps in the process. The information is taken from historical sources and from central and regional archives. The study allowed to conclude that the administrative-territorial transformation of XVIII – early XX centuries can be considered an experiment for the development of the Plurinational state. This experiment is caused by the consolidation of the national periphery and to neutralize the threat of separatism and the need to protect the territories from external enemies.

    In this study, the annual cycle of the gonadal steroids testosterone (T), 11-ketotestosterone (11-KT), 17β-estradiol (E2) and 17α, 20β-dihydroxy-4-pregnen-3-one (DHP) was determined using radioimmunoassay and then compared for two populations of rainbow trout, XX diploid females (n = 40) and XXX triploid females (n = 15). In females, E2 and DHP levels were found to be significantly related to body weight (r = 0.22513; p 0.001, respectively). In this group, E2 concentrations peaked in November (25.05 ng/ml), while maximum DHP levels, only measurable from October to April, were attained in February (64.14 ng/ml). No significant differences in hormone ranges related to egg output ability were observed. Finally, sex steroid concentrations were low in the triploid female XXX fish compared to the female XX population. Nevertheless, maximum T (33.85 ng/ml) and 11-KT (32.35 ng/ml) levels were recorded in January, for XXX. The levels for these two hormones are relatively high and are also significantly associated (r = 0.8430; p < 0.0001). Diploid females showed significantly higher levels of E2 than triploids over the 12-month study period. The female triploid fish produced the lowest steroid hormone levels, such that these would be the most suitable for human consumption. © 2012 Blackwell Verlag GmbH.

    The 46, XX male disorder of sex development (DSD) is a rare genetic condition. Here, we report the case of a 46, XX SRY-negative male with complete masculinization. The coding region and exon/intron boundaries of the DAX1, SOX9 and RSPO1 genes were sequenced, and no mutations were detected. Using whole genome array analysis and real-time PCR, we identified a approximately 74-kb duplication in a region approximately 510-584 kb upstream of SOX9 (chr17:69,533,305-69,606,825, hg19). Combined with the results of previous studies, the minimum critical region associated with gonadal development is a 67-kb region located 584-517 kb upstream of SOX9. The amplification of this region might lead to SOX9 overexpression, causing female-to-male sex reversal. Gonadal-specific enhancers in the region upstream of SOX9 may activate the SOX9 expression through long-range regulation, thus triggering testicular differentiation.

    We discuss high-resolution solar flare iron line spectra recorded between 1.82 and 1.97 A by a spectrometer flown by the Naval Research Laboratory on an Air Force spacecraft launched on 1979 February 24. The emission line spectrum is due to inner-shell transitions in the ions Fe XX-Fe XXV. Using theoretical spectra and calculations of line intensities obtained by methods discussed by Merts, Cowan, and Magee, we derive electron temperatures as a function for time of two large class X flares. These temperatures are deduced from intensities of lines of Fe XXIII, Fe XXII, and Fe XXIV. Previous measurements by us have involved only lines of Fe XXIV and Fe XXV. We discuss the determination of the differential emission measure between about 12 x 10 6 K and 20 x 10 6 K using these temperatures. The possibility of determining electron densities in flare and tokamak plasmas using the inner-shell spectra of Fe XXI and Fe XX is discussed. We also discuss recent theoretical work by Mewe and Schrijver based on atomic data of Grineva, Safronova, and Urnov

  18. Size-dependent thermoelasticity

    Directory of Open Access Journals (Sweden)

    Ali R. Hadjesfandiari

    Full Text Available In this paper a consistent theory is developed for size-dependent thermoelasticity in heterogeneous anisotropic solids. This theory shows that the temperature change can create not only thermal strains, but also thermal mean curvatures in the solids. This formulation is based on the consistent size-dependent continuum mechanics in which the couple-stress tensor is skew-symmetric. Here by including scale-dependent measures in the energy and entropy equations, the general expressions for force- and couple-stresses, as well as entropy density, are obtained. Next, for the linear material the constitutive relations and governing coupled size-dependent thermoelasticity equations are developed. For linear material, one can see that the thermal properties are characterized by the classical symmetric thermal expansion tensor and the new size-dependent skew-symmetric thermal flexion tensor. Thus, for the most general anisotropic case, there are nine independent thermoelastic constants. Interestingly, for isotropic and cubic materials the thermal flexion tensor vanishes, which shows there is no thermal mean curvature

    This paper discusses a Space Power Subsystem Sizing program which has been developed by the Aerospace Power Division of Wright Laboratory, Wright-Patterson Air Force Base, Ohio. The Space Power Subsystem program (SPSS) contains the necessary equations and algorithms to calculate photovoltaic array power performance, including end-of-life (EOL) and beginning-of-life (BOL) specific power (W/kg) and areal power density (W/m 2 ). Additional equations and algorithms are included in the spreadsheet for determining maximum eclipse time as a function of orbital altitude, and inclination. The Space Power Subsystem Sizing program (SPSS) has been used to determine the performance of several candidate power subsystems for both Air Force and SDIO potential applications. Trade-offs have been made between subsystem weight and areal power density (W/m 2 ) as influenced by orbital high energy particle flux and time in orbit

    A Picture Archiving and Communications System (PACS) must be able to support the image rate of the medical treatment facility. In addition the PACS must have adequate working storage and archive storage capacity required. The calculation of the number of images per minute and the capacity of working storage and of archiving storage is discussed. The calculation takes into account the distribution of images over the different size of radiological images, the distribution between inpatient and outpatient, and the distribution over plain film CR images and other modality images. The support of the indirect clinical image load is difficult to estimate and is considered in some detail. The result of the exercise for a particular hospital is an estimate of the average size of the images and exams on the system, of the number of gigabytes of working storage, of the number of images moved per minute, of the size of the archive in gigabytes, and of the number of images that are to be moved by the archive per minute. The types of storage required to support the image rates and the capacity required are discussed.

His mother was phenotypically normal except for a double ureter and bifid renal pelvis as in his son. She had a supernumerary ring (18) in 10% of blood lymphocytes, karyotype mos 47,XX,+r(18)(::p11→q21::)[10]/46,XX[90]. Familial ring (18) is a rare cytogenetic abnormality. This is the first report of a mother with a supernumerary ring (18) and a son with ring (18) mosaicism. Interestingly, the son showed a true mosaicism (mixoploidy) of ring (18) and normal cells. The mother's 46,XX cells could be easily explained by mitotic instability and ring loss during cell division. However, the coexistence of ring (18) and normal cells in the son is unusual. Possibly, during early postzygotic divisions of a 47,XY,+r(18) zygote, two (possibly subsequent) genetic events could have occurred, one when one normal chromosome 18 was lost (resulting in a cell line with ring 18), and one when the ring 18 was lost (resulting in a cell line without ring, "escape to normal"). Alternatively, the zygote of the son could have been 46,XY,r(18), and postzygotic loss of the ring 18 could have resulted in monosomy 18 cells followed by duplication of chromosome 18 in these cells (a rare mechanism for cell survival previously described as "compensatory" isodisomy).

    Palmoplantar hyperkeratosis with squamous cell carcinoma of skin and sex reversal (MIM # 610644) is a clinically distinctive form of SRY-negative 46,XX disorder of sex development. It is a rare autosomal recessive disorder caused due to biallelic loss of function mutations in RSPO1 gene. RSPO1 acts by activating the canonical β-catenin pathway and is one of the most important genes controlling female gonadal differentiation. RSPO1-associated disorders of sex development have been described only in three instances in the past. We report fourth such case with additional findings and perform a comparative review of previous phenotypic descriptions, thereby expanding the clinical phenotype of this syndrome. © 2018 Wiley Periodicals, Inc.

    In this paper, we demonstrate that the modified equation of Emden type (MEE), x-doubledot + αxx-dot + βx 3 = 0, is integrable either explicitly or by quadrature for any value of α and β. We also prove that the MEE possesses appropriate time-independent Hamiltonian functions for the full range of parameters α and β. In addition we show that the MEE is intimately connected with two well-known nonlinear models, namely the equation of force-free Duffing-type oscillator and the two-dimensional Lotka-Volterra equation, and thus the complete integrability of the latter two models can also be understood in terms of the MEE

    We have observed spectra from highly charged zinc ions in a variety of laser-produced plasmas. Spectral features that are Na- and Mg-like satellites to high-n Rydberg transitions in the Ne-like Zn XXI spectrum are analyzed and modeled. Identifications and analysis are made by comparison with highly accurate atomic structure calculations and steady state collisional-radiative models. Each observed Zn XX and Zn XIX feature comprises up to ≅2 dozen individual transitions, these transitions are excited principally by dielectronic recombination through autoionizing levels in Na- and Mg-like Zn 19+ and Zn 18+ . We find these satellites to be ubiquitous in laser-produced plasmas formed by lasers with pulse lengths that span four orders of magnitude, from 1 ps to ≅10 ns. The diagnostic potential of these Rydberg satellite lines is demonstrated

  3. Sox9 gene regulation and the loss of the XY/XX sex-determining mechanism in the mole vole Ellobius lutescens.

    In most mammals, the Y chromosomal Sry gene initiates testis formation within the bipotential gonad, resulting in male development. SRY is a transcription factor and together with SF1 it directly up-regulates the expression of the pivotal sex-determining gene Sox9 via a 1.3-kb cis-regulatory element (TESCO) which contains an evolutionarily conserved region (ECR) of 180 bp. Remarkably, several rodent species appear to determine sex in the absence of Sry and a Y chromosome, including the mole voles Ellobius lutescens and Ellobius tancrei, whereas Ellobius fuscocapillus of the same genus retained Sry. The sex-determining mechanisms in the Sry-negative species remain elusive. We have cloned and sequenced 1.1 kb of E. lutescens TESCO which shares 75% sequence identity with mouse TESCO indicating that testicular Sox9 expression in E. lutescens might still be regulated via TESCO. We have also cloned and sequenced the ECRs of E. tancrei and E. fuscocapillus. While the three Ellobius ECRs are highly similar (94-97% sequence identity), they all display a 14-bp deletion (Δ14) removing a highly conserved SOX/TCF site. Introducing Δ14 into mouse TESCO increased both basal activity and SF1-mediated activation of TESCO in HEK293T cells. We propose a model whereby Δ14 may have triggered up-regulation of Sox9 in XX gonads leading to destabilization of the XY/XX sex-determining mechanism in Ellobius. E. lutescens/E. tancrei and E. fuscocapillus could have independently stabilized their sex determination mechanisms by Sry-independent and Sry-dependent approaches, respectively.

    Rittenberg, V.

    1983-01-01

    Fischer's finite-size scaling describes the cross over from the singular behaviour of thermodynamic quantities at the critical point to the analytic behaviour of the finite system. Recent extensions of the method--transfer matrix technique, and the Hamiltonian formalism--are discussed in this paper. The method is presented, with equations deriving scaling function, critical temperature, and exponent v. As an application of the method, a 3-states Hamiltonian with Z 3 global symmetry is studied. Diagonalization of the Hamiltonian for finite chains allows one to estimate the critical exponents, and also to discover new phase transitions at lower temperatures. The critical points lambda, and indices v estimated for finite-scaling are given

The study of urban riots allows us to analyze how a society that was going through the first stages of a modernization process, produced a form of lower-class protest characterized by the destruction of property, the lack of a permanent form of organization, certain manifestations of racial outrage, and above all, notions of legitimacy sanctioned by tradition. In addition, the study of urban riots allows us to understand how lower classes could influence economic and political developments, often for their own benefit. In this attempt, the native masses of early 20th century Lima carried on a daily struggle whose scenario was the labor market witch, on occasion, was characterized by high levels of violence, such as the May 1909 riots. As the article details, Chinese people were the target of the crowd’s fury, due to the belief that Chinese workers were displacing locals from their jobs and were a factor in the overall decline in salary rates.

    The purpose of the study was to create detector element-specific angular correction factors for each detector of the MatriXX planar ion chamber array and compare them to vendor-default angular correction factors. Additionally, the impact of both factors on gamma index was quantified using two corrections. The correction factor of each element is determined irradiating the detector at different incidences by the ratio of the calculated expected dose to the MatriXX measured dose as a gantry angle function. To evaluate its impact, sixty-five pre-irradiated patient-specific dose validations were re-analyzed using the gamma index with: 3%/3 mm, 2%/2 mm, 1%/1 mm criteria. The factors for 6 MV were found to differ (7%) from the default ones for specific angles particularly for 85 degree centigrade to 95 degree centigrade. For 10 MV, differences (1.0%) existed when correction factors were created using various ROI's. Two corrections were proposed, absolute differences for 3%/3 mm, 2%/2 mm, and 1%/1 mm were up to 1.5%, 4.2% and 4.1% ( p < 0.01), respectively. Large differences in the default and specific factors were noted for 6 MV and lead to improvement of the absolute gamma index value of up to 4.2%. In general, gamma index value increases for patient specific dose validations when using device specific factors. (Author)

    The Size Reduction Machine (SRM) is a mobile platform capable of shearing various shapes and types of metal components at a variety of elevations. This shearing activity can be performed without direct physical movement and placement of the shear head by the operator. The base unit is manually moved and roughly aligned to each cut location. The base contains the electronics: hydraulic pumps, servos, and actuators needed to move the shear-positioning arm. The movable arm allows the shear head to have six axes of movement and to cut to within 4 inches of a wall surface. The unit has a slick electrostatic capture coating to assist in external decontamination. Internal contamination of the unit is controlled by a high-efficiency particulate air (HEPA) filter on the cooling inlet fan. The unit is compact enough to access areas through a 36-inch standard door opening. This paper is an Innovative Technology Summary Report designed to provide potential users with the information they need to quickly determine if a technology would apply to a particular environmental management problem. They also are designed for readers who may recommend that a technology be considered by prospective users

Las transiciones o cambios sufridos se pueden visualizar en el siglo XX con el régimen de Porfirio Díaz, que duró más de treinta años, en donde el país se vio impactado por la industrialización y la introducción de arte y arquitectura de tipo ecléctica, al periodo de la revolución en donde se quería despojar un régimen autoritario y buscar una identidad, hecho que encaminó la proclamación de la Constitución (1917, posteriormente en 1929 la permanencia de un partido político, que permaneció setenta años en la presidencia, el cual se desgastó en conmemorar a personajes de la política en parques y jardines, hasta la denominada alternancia signo de una aparente democracia. Todos estos periodos han caracterizado a México y sus espacios abiertos, incluidas las actividades sociales. El presente trabajo aborda el estudio del espacio público que se desarrolló durante el siglo XX impactado por las dictaduras tanto oficiales como las no oficiales definidas en tres momentos, en un primer ciclo con el gobierno porfirista, seguido de la etapa postrevolucionaria o constitucionalista y el último caracterizado por una visión unipartidista con la entrada de el PNR1 posteriormente PRI2.

    2006-01-01

    The majority of higher organisms in the marine environment display indeterminate growth; that is, they continue to grow throughout their life, limited by an asymptotic size. We derive the abundance of species as a function of their asymptotic size. The derivation is based on size-spectrum theory......, where population structure is derived from physiology and simple arguments regarding the predator-prey interaction. Using a hypothesis of constant satiation, which states that the average degree of satiation is independent of the size of an organism, the number of individuals with a given size is found...... to be proportional to the weight raised to the power -2.05, independent of the predator/prey size ratio. This is the first time the spectrum exponent has been derived solely on the basis of processes at the individual level. The theory furthermore predicts that the parameters in the von Bertalanffy growth function...

The 19th Century inclusive position of José Cecilio del Valle and the more exclusive one conceived by Batres Jauregui are analyzed, as well as the reasons why these types of ideas are still prevailing. In the 20th Century, the analysis includes exclusion defenders such as Horacio Altamirano and their opposites, like Juárez Muñoz. The whole article is pervaded with the ideas of the so called Generación del 20, the analysis of which is particularly original and important to understand arguments which have prevailed till the present day and are used to support theories for the inclusion and/or exclusion of Indians in the nation project of Guatemala.

    Full Text Available Este artigo analisa a especialização da produção agrícola nas regiões e nas propriedades rurais do estado de São Paulo no início do século XX, após décadas de transformações causadas pela difusão da lavoura do café. O trabalho utiliza dados de mais de 40 mil propriedades rurais para examinar a estrutura de produção e a especialização produtiva em onze regiões que cobrem a totalidade do território do estado de São Paulo no auge da economia cafeeira. Além das regiões, o artigo aborda como as propriedades rurais distribuíram seus recursos produtivos entre produto de exportação (café e produtos destinados ao consumo interno. A análise traz à luz novas evidências, corroborando parte da literatura, mas divergindo de outras ideias estabelecidas na historiografia. No início do século XX, virtualmente todas as regiões de São Paulo produziam café, mas quase todas elas se especializaram em mais de um produto agrícola, com a exceção da região da Mogiana. Além das grandes propriedades ressaltadas na literatura, as pequenas propriedades também foram atraídas para a produção de exportação e se especializaram na produção do café. Por sua vez, as grandes propriedades não só se especializaram na produção de alimentos (além do café, mas dominaram a oferta dos principais produtos destinados ao mercado doméstico.

  18. Sauropod dinosaurs evolved moderately sized genomes unrelated to body size.

    Sauropodomorph dinosaurs include the largest land animals to have ever lived, some reaching up to 10 times the mass of an African elephant. Despite their status defining the upper range for body size in land animals, it remains unknown whether sauropodomorphs evolved larger-sized genomes than non-avian theropods, their sister taxon, or whether a relationship exists between genome size and body size in dinosaurs, two questions critical for understanding broad patterns of genome evolution in dinosaurs. Here we report inferences of genome size for 10 sauropodomorph taxa. The estimates are derived from a Bayesian phylogenetic generalized least squares approach that generates posterior distributions of regression models relating genome size to osteocyte lacunae volume in extant tetrapods. We estimate that the average genome size of sauropodomorphs was 2.02 pg (range of species means: 1.77-2.21 pg), a value in the upper range of extant birds (mean = 1.42 pg, range: 0.97-2.16 pg) and near the average for extant non-avian reptiles (mean = 2.24 pg, range: 1.05-5.44 pg). The results suggest that the variation in size and architecture of genomes in extinct dinosaurs was lower than the variation found in mammals. A substantial difference in genome size separates the two major clades within dinosaurs, Ornithischia (large genomes) and Saurischia (moderate to small genomes). We find no relationship between body size and estimated genome size in extinct dinosaurs, which suggests that neutral forces did not dominate the evolution of genome size in this group.

    Cross sections and rate coefficients for excitation of the 2s 2 2p 52 P 3/2 -2s 2 2p 52 P 1/2 transition in fluorine-like Fe XVIII and Ni XX by proton (p), deuteron (d), triton (t) and α-particle (α) impact have been calculated using the close-coupled impact parameter method. At temperatures close to or below those of maximum Fe XVIII and Ni XX fractional abundance in ionisation equilibrium, the p,d and t rates are found to be comparable and are much greater than the rates due to α collisions. However, at high temperatures the situation is reversed, with the α rates being about a factor of two larger than those due to the other particles. The effects of adopting the present atomic data in calculations of the electron density or ion temperature sensitive emission line ratios are briefly discussed. (author)

    Full Text Available Body size, and, by extension, growth has impacts on physiology, survival, attainment of sexual maturity, fecundity, generation time, and population dynamics, especially in ectotherm animals that often exhibit extensive growth following attainment of sexual maturity. Frequently, growth is analyzed at the population level, providing useful population mean growth parameters but ignoring individual variation that is also of ecological and evolutionary significance. Our long-term study of Lake Erie Watersnakes, Nerodia sipedon insularum, provides data sufficient for a detailed analysis of population and individual growth. We describe population mean growth separately for males and females based on size of known age individuals (847 captures of 769 males, 748 captures of 684 females and annual growth increments of individuals of unknown age (1,152 males, 730 females. We characterize individual variation in asymptotic size based on repeated measurements of 69 males and 71 females that were each captured in five to nine different years. The most striking result of our analyses is that asymptotic size varies dramatically among individuals, ranging from 631-820 mm snout-vent length in males and from 835-1125 mm in females. Because female fecundity increases with increasing body size, we explore the impact of individual variation in asymptotic size on lifetime reproductive success using a range of realistic estimates of annual survival. When all females commence reproduction at the same age, lifetime reproductive success is greatest for females with greater asymptotic size regardless of annual survival. But when reproduction is delayed in females with greater asymptotic size, lifetime reproductive success is greatest for females with lower asymptotic size when annual survival is low. Possible causes of individual variation in asymptotic size, including individual- and cohort-specific variation in size at birth and early growth, warrant further

  5. On the Relationship between Pollen Size and Genome Size

    Directory of Open Access Journals (Sweden)

    Charles A. Knight

    2010-01-01

    Full Text Available Here we test whether genome size is a predictor of pollen size. If it were, inferences of ancient genome size would be possible using the abundant paleo-palynolgical record. We performed regression analyses across 464 species of pollen width and genome size. We found a significant positive trend. However, regression analysis using phylogentically independent contrasts did not support the correlated evolution of these traits. Instead, a large split between angiosperms and gymnosperms for both pollen width and genome size was revealed. Sister taxa were not more likely to show a positive contrast when compared to deeper nodes. However, significantly more congeneric species had a positive trend than expected by chance. These results may reflect the strong selection pressure for pollen to be small. Also, because pollen grains are not metabolically active when measured, their biology is different than other cells which have been shown to be strongly related to genome size, such as guard cells. Our findings contrast with previously published research. It was our hope that pollen size could be used as a proxy for inferring the genome size of ancient species. However, our results suggest pollen is not a good candidate for such endeavors.

Soportes sociales y materiales discursivos que a su vez coincidieron con la problematización de las fronteras genérico-sexuales y las identidades deseables que debían integrar la comunidad imaginada de la nación, en tanto, asociación limitada y soberana, siguiendo la propuesta de Benedict Anderson, vinculada por medio de lazos fraternales homosociales que daban cuenta de su carácter hegemónico como excluyente frente a lo considerado diverso como lo hibrido.

    Full Text Available Resumen Este artículo rescata la obra de teatro guiñol Las calenturas de Don Ferruco, televisada a finales de la década de 1950 para promover la erradicación del paludismo en México como un útil instrumento de educación para la salud. Se analiza cómo la difusión del teatro guiñol educativo en la televisión mexicana evidenció la necesidad de mantener vigente la enseñanza dirigida a prevenir enfermedades y se subraya la importancia de la televisión como una producción educativa para promover la salud hacia mediados del siglo XX. El artículo muestra los inicios de su uso como una herramienta de especial importancia para lo que posteriormente sería la masificación de los discursos emitidos por la Secretaría de Salubridad y Asistencia.

    Full Text Available Con el propósito de identificar las características más relevantes que tipifican a la psicología latinoamericana hacia fines del siglo XX, se señalan y discuten seis notas dominantes: su orientación científica, el carácter dependiente, la escasa originalidad, la relevancia social y su permeabilidad política, la preferencia por la investigación aplicada y su interés por el hombre como objeto central de sus trabajos. Se señala como limitación para establecer generalizaciones, el que las observaciones se basan solamente en las naciones latinoamericanas más activas en la generación de conocimientos psicológicos. In order to identify the most important characteristics that describe the Latin American Psychology at the end of the century, six main issues are discussed: the scientific orientation, the dependency characteristic, the lack of an original approach, the social meaning, the politic permeability, the emphasis on applied research, and the interest in the person as the central object of study. The fact that these observations are based on the more active nations in the generation of psychological knowledge could be a limitation in the generalization of the findings.

    We have synthesized a series of intermetallic ternary phosphide chalcogenide superconductors, AP2-xXx (A = Zr, Hf; X = S, Se), using the high-pressure synthesis technique. These materials have a PbFCl-type crystal structure (space group P4/nmm) when x is greater than 0.3. The superconducting transition temperature Tc changes systematically with x, yielding dome-like phase diagrams. The maximum Tc is achieved at approximately x = 0.7, at which point the Tc is 6.3 K for ZrP2-xSex (x = 0.75), 5.5 K for HfP2-xSex (x = 0.7), 5.0 K for ZrP2-xSx (x = 0.675), and 4.6 K for Hfp2-xSx (x = 0.5). They are typical type-II superconductors and the upper and lower critical fields are estimated to be 2.92 T at 0 K and 0.021 T at 2 K for ZrP2-xSex (x = 0.75), respectively.

    Full Text Available The situation of women-musicians in Poland – a case study from the beginning of the XX century to the present day The aim of this article is to identify the changes, based on the biographies of selected women-musicians, which affected traditional musical culture from the strict adherence to roles and functions for both genders to the total collapse of these barriers. There are no observations concerning women-musicians in the XIX century or in the centuries before, neither in Polish ethnography nor in the ethomusicological literature. Women probably played musical instruments, but only at home or while tending domestic animals, however there is a lack of any source confirmation of public performances of women musicians. On account of the rare literature on the topic of gender studies in the field of Polish traditional music and the lack of the gender-thread in the remaining ethnomusicological literature, information on the topic of the current position of women-musicians was gathered first of all during interviews with them and with their families. The analysis is related to the way they speak about their own activities, performances, experiences. The author refers to opinions of only some selected interviewees, the most characteristic of particular generations. The first generation is represented by women born near the end of the XIX century, the second by women born before World War II, the third by women born directly after World War II. Women born after the 50’s and 60’s of the XX century are part of the fourth generation, because at that time the differences in the gender situation had become less apparent.   Sytuacja kobiet muzykantek w Polsce – studium przykładów od początku XX wieku do dziś Celem niniejszego artykułu jest scharakteryzowanie przebiegu zmian zachodzących w tradycyjnej kulturze muzycznej, na postawie życiorysów wybranych muzykantek, począwszy od ścisłego przestrzegania ról i funkcji obydwu p

    Full Text Available O presente trabalho traz à baila a discussão sobre a antroponímia de uma parcela da população afrodescendente do Brasil. O texto tenta mostrar, relacionando a história da Bahia e do Brasil, o porquê de os nomes próprios africanos terem praticamente se extinguido no país, revelando possíveis fatores que levaram os negros a adotar nomes de origem europeia. Para tanto, faz-se uso do livro de matrícula da Sociedade Protetora dos Desvalidos (SPD, uma irmandade negra de Salvador que existe desde 1832, quando ainda havia o regime escravocrata no Brasil. Analisam-se aqui os nomes presentes no livro a partir da segunda década do século XX. A partir da leitura de textos que tratam da antroponímia no Brasil e em Portugal, bem como de textos que traçam a história da escravidão brasileira e da SPD, além da análise dos nomes presentes no livro de matrícula, confirma-se a hipótese do uso de nomes de origem europeia pelos negros brasileiros e procura-se criar hipóteses para a explicação de tal fato.

    Sex-specific markers are powerful tools for identifying sex-determination system in various animals. Bighead carp (Hypophthalmichehys nobilis) and silver carp (Hypophthalmichthys molitrix) are two of the most important edible fish in Asia, which have a long juvenility period that can lasts for 4-5 years. In this study, we found one sex-specific marker by next-generation sequencing together with bioinformatics analysis in bighead carp. The male-specific markers were used to perform molecular sexing in the progenies of artificial gynogenetic diploids and found all progenies (n = 160) were females. Meanwhile, around 1 : 1 sex ratio was observed in a total of 579 juvenile offspring from three other families. To further extend the male-specific region, we performed genome walking and got a male-specific sequence of 8,661 bp. Five pairs of primers were designed and could be used to efficiently distinguish males from females in bighead carp and silver carp. The development of these male-specific markers and results of their molecular sexing in different populations provide strong evidence for a sex determination system of female homogametry or male heterogametry (XX/XY) in bighead carp and silver carp. To the best of our knowledge, this is the first report of effective sex-specific markers in these two large carp species. © The Author(s) 2018.

  19. La ciudad herida: Siete ejemplos paradigmáticos de rehabilitación urbana en la segunda mitad del siglo XX

    Full Text Available En la historia del urbanismo, la segunda mitad del siglo XX marca un punto de inflexión. Los métodos de desarrollo urbano aplicados hasta la fecha ya no consiguen dar respuesta a los problemas surgidos en el corazón de las ciudades: guetos, inseguridad o delincuencia. Resulta necesario buscar nuevos métodos para la recuperación del pulso vital de nuestros barrios. Kreuzberg en Berlín, el centro histórico de Bolonia, Le Marais en París, Fener y Balat en Estambul, Molenbeek en Bruselas, Mouraria en Lisboa y Lavapiés en Madrid se han convertido en ejemplos paradigmáticos de la nueva idea de rehabilitación urbana. La diversidad social, que evita la creación de guetos; la calidad de los espacios públicos, que favorece las relaciones interpersonales; y la salvaguarda, que mantiene y fortalece la imagen que tenemos de nuestro entorno urbano, se convierten en conceptos necesarios para recuperar nuestra "ciudad herida".

    Full Text Available El trabajo amplió el conocimiento que posee la historiografía especializada sobre las problemáticas de la migración y la tuberculosis en las primeras décadas del siglo XX, en el contexto de la migración interna que llegaba a la provincia y a la ciudad de Córdoba. Articulamos bibliografía especializada y testimonios de la época dividiendo la indagación en dos partes. Por un lado, analizamos el tipo de migración que llegaba a la ciudad en el marco de un sistema antituberculoso en construcción. Por el otro, estudiamos los discursos y concepciones que surgieron desde los actores de poder locales ante un escenario caracterizado por un tipo de migración de escasos recursos. El trabajo identificó la existencia de posturas que tendieron a convertir al inmigrante tuberculoso en el responsable tanto del contagio a los residentes “sanos”, la “invasión” de enfermos a la provincia y a la ciudad de Córdoba, así como de llevar al sistema antituberculoso al límite de sus posibilidades de respuesta.
