Prenatal diagnosis and 47,XXY.  

PubMed

In this contribution, we consider detection of 47,XXY by a variety of available methods. These include traditional invasive procedures, screening with maternal serum analytes and fetal ultrasound, and most recently cell-free fetal DNA. Since its introduction in the late 1960s, prenatal genetic diagnosis has evolved greatly. Serendipitious detection of 47,XXY was not infrequent when prenatal genetic diagnosis routinely involved testing by the invasive procedures CVS and amniocentesis. In 2013 this is much less common and relatively few pregnancies in the U.S. and Europe are tested without prior screening protocols, traditionally maternal serum analyte and fetal ultrasound (NT). These protocols are not designed to identify 47,XXY or other X-chromosome aneuploides and with screening by analysis of cell-free DNA in maternal blood, this situation may or may not be altered. Increased numbers of cases could be detected if intake increases and vendors offer information on 47,XXY. A further consideration is that ability of array CGH to detect microdeletions or microduplications below resolution of a karyotype could make return to direct testing using an invasive procedure attractive.

Testicular tumor in an XXY dog.  

PubMed

Klinefelter syndrome has been described in various species in addition to humans, including cat, pig, horse, and dog. It is associated with low levels of male hormones, sterility, breast enlargement, and small testes. Patients with Klinefelter syndrome have a higher risk for several malignancies. Knowledge about genetic disorders of the dog is comparatively sparse. This is mainly due to the difficult canine karyotypic pattern. We present the case of a canine patient with clinically and cytogenetically confirmed Klinefelter syndrome who developed a testicular tumor at a very early age. Testicular tumors are common in dogs, normally affecting elderly patients (median age, >9 years). In the present case, however, the dog was only 5 years old, allowing the conclusion that the XXY constitution may have promoted the early onset of testicular tumor disease. PMID:18503830

47,XXY males: sex chromosomes and tooth size.  

PubMed

Permanent tooth crowns of 47,XXY males were found to be generally larger than those of control males and females and their first-degree male and female relatives. These results suggest that tooth-size increase in 47,XXY males is due to a direct genetic effect and support the concept of the presence of a specific growth gene (or genes) in the human X and Y chromosomes. The effect of this gene (or genes) seems to be the promotion of tooth growth, and the Y chromosome is more effective than the X chromosome in this respect. PMID:7446531

Oscillator strengths and lifetimes in Ge XXI  

NASA Astrophysics Data System (ADS)

We have calculated energy splittings of 53 fine-structure levels as well as oscillator strengths and radiative decay rates for all electric-dipole-allowed and intercombination transitions among the (1s22s22p6)3s2(1S), 3s3p(1,3Po), 3s3d(1,3D), 3s4s(1,3S), 3s4p(1,3Po), 3s4d(1,3D), 3s4f(1,3Fo), 3p2(1S,3P,1D), 3p3d(1,3Po,1,3Do,1,3Fo), 3p4s(1,3Po) and 3d2(1S,3P,1D,3F,1G) states of Ge XXI, using extensive configuration-interaction (CI) wavefunctions, obtained with the CIV3 computer code of Hibbert. The important relativistic effects in intermediate coupling are incorporated by means of the Breit-Pauli Hamiltonian. In order to keep our calculated energy splittings as close as possible to the experimental values, we have made small adjustments to the diagonal elements of the Hamiltonian matrices. Our excitation energies, including their ordering, are in excellent agreement with the available experimental results. The enormous mixing among several fine-structure levels makes it very difficult to identify them correctly with the result that their positions in the calculation of Ivanova et al are interchanged compared to our results and the experimental values. From our transition probabilities, we have also calculated radiative lifetimes of some fine-structure levels. Our calculated oscillator strengths and the lifetimes are found to be in good agreement with the other available theoretical results. In this calculation, we also predict new data for several fine-structure levels where no other theoretical and/or experimental results are available.

[Medicopsychosocial syndrome of polygonosomies (XXX, XXY, XYY, syndromes etc...)].  

PubMed

This is an attempt to describe a common syndrom of polygonosomy. Medical, psychological and social incidences of XXX, XXY, XYY, genotypes indicate that these chromosomal aberrations share identical features: phenotypic abnormalities (high stature, dermatoglyphes abnormalities), neuropsychic troubles (neurological symptoms and mental fragility) and antisocial tendancy. One can suppose that at least some polygonosomic persons have a minimal brain dysfunction (or damage), which causes more vulnerability to environnement, deprivation and stress. Relational, educational and socio-economical factors appear now to have a marked role in the etiopathogenesis of these psychiatric troubles. Some forensic and ethical problems of human genetic research are reviewed, such as the so-called "criminal chromosome", supplementary Y chromosome, a myth based upon false and premature scientific assertions.

Expanding the phenotypic profile of boys with 47, XXY: the impact of familial learning disabilities.  

PubMed

The aim of the study was to examine the impact of familial learning disabilities (FLD) on the phenotypic profile of 47, XXY males and the possibility that 47, XXY males with more severe cognitive deficits may be partially a consequence of familial dyslexia/reading disorder. We wondered if FLD could pose an additional risk for complex neurodevelopmental differences in 47, XXY. The neurodevelopmental profile of males with 47, XXY has been characterized by developmental dyspraxia, language-based learning disorders, executive dysfunction, reading, and attentional deficits. One hundred eighteen boys with 47, XXY diagnosed prenatally who did not receive early hormonal treatment were divided into two groups based on positive histories of FLD and given comprehensive neurodevelopmental evaluations between 36 and 108 months. The assessments included intelligence (nonverbal and verbal), neuromotor (fine and gross), speech, and language. The group with FLD performed significantly lower in multiple neurodevelopmental domains of the Wechsler of VIQ P = 0.015, FSIQ P = 0.0005, the Brief IQ P = 0.0525 of the Leiter, in Auditory Comprehension P = 0.0505, Expressive Communication P = 0.0055, and neuromotor domains of Manual Coordination P = 0.0032, Fine Motor Control P = 0.0378, and Motor Coordination P = 0.008. Our study demonstrates the influence of FLD on neurodevelopment and expands the phenotypic profile of 47, XXY, suggesting some neurodevelopmental variability is attributable to other factors than the additional X. FLD may increase the vulnerability of the 47, XXY children and anticipatory guidance should be provided to families. PMID:24715716

Tdy-negative XY, XXY and XYY female mice: breeding data and synaptonemal complex analysis.  

PubMed

In this paper we have compared the breeding performance of Tdy-negative XY, XXY and XYY females to assess the relative importance of the lack of a second X chromosome compared with the presence of a Y chromosome, in reducing fertility. The XY females were of poor fertility, although five of twelve produced at least one offspring. The XXY females had larger, more frequent litters, and a longer reproductive lifespan, implicating the lack of a second X as the major cause of the poor fertility of XY females. Nevertheless, XYY females appeared to be more seriously affected than the XY females, suggesting that the presence of the Y may be a contributory factor. Pachytene analysis demonstrated that the Y is a very inefficient pairing partner for the X during female meiosis. In XY females only 11% of pachytene cells had the X and Y paired; in XXY females the two X chromosomes paired and the Y was almost always a univalent, while in XYY females the X paired with a Y in only 15% of pachytene cells. The presence of unpaired sex chromosomes has previously been implicated as a cause of oocyte loss during pachytene, and the proportion of cells with unsynapsed sex chromosomes decreased as pachytene proceeded, suggesting that they were progressively eliminated. Significantly, protection against elimination was afforded not only by synapsis between sex chromosomes, but also by self-synapsis if a sex chromosome remained as a univalent. It is concluded that sex chromosome univalence leading to pachytene oocyte failure is responsible for the postnatal oocyte deficiency seen in XY females. A separate study has shown that XXY females have a similar level of oocyte deficiency. It is suggested that the presence of a second X chromosome improves the fertility of XXY females, compared with XY females, by improving oocyte quality and by eliminating the production of lethal XY and OY zygotes. The genotype frequencies for the offspring of XY and XYY females differed from those predicted from the pachytene data. The XY females showed a marked deficiency of XO offspring compared with XXY and XYY aneuploid offspring, whereas the XXY females had fewer than expected XXY and XYY aneuploid offspring. PMID:8464005

47,XXY Klinefelter syndrome: clinical characteristics and age-specific recommendations for medical management.  

PubMed

47,XXY (Klinefelter syndrome) is the most frequent sex chromosomal disorder and affects approximately one in 660 newborn boys. The syndrome is characterized by varying degrees of cognitive, social, behavioral, and learning difficulties and in adulthood additionally primary testicular failure with small testes, hypergonadotropic hypogonadism, tall stature, and eunuchoid body proportions. The phenotype is variable ranging from "near-normal" to a significantly affected individual. In addition, newborns with Klinefelter syndrome generally present with a normal male phenotype and the only consistent clinical finding in KS is small testes, that are most often not identified until after puberty. Decreased awareness of this syndrome among health professionals and a general perception that all patients with 47,XXY exhibit the classic textbook phenotype results in a highly under-diagnosed condition with up to 75% of the patients left undetected. Typically, diagnosis is delayed with the majority of patients identified during fertility workup in adulthood, and only 10% of patients diagnosed prior to puberty. Early detection of this syndrome is recommended in order to offer treatment and intervention at the appropriate ages and stages of development for the purpose of preventing osteopenia/osteoporosis, metabolic syndrome, and other medical conditions related to hypogonadism and to the XXY as well as minimizing potential learning and psychosocial problems. The aim of this review is to present the clinical aspects of XXY and the age-specific recommendations for medical management. © 2013 Wiley Periodicals, Inc. PMID:23345262

47,XXY/48,XXXY/49,XXXXY mosaic with hydrocephaly: a case report and review of the literature  

PubMed Central

Klinefelter's syndrome is a frequent genetic sexual alteration in males, associated with the 47,XXY aneuploidy. Several syndrome variants are caused by different X and Y polysomy and mosaicisms, including the 49,XXXXY condition described by some authors as Fraccaro's syndrome. Mosaics with three or more different chromosomal lines are very rare. Here, we describe a case with XXY/XXXY/XXXXY mosaic in a newborn with clinical features of Fraccaro's syndrome, but also with obstructive hydrocephaly which has not been reported previously.

The occurrence of double aneuploidy in the same individual is a relatively rare phenomenon. We describe twin newborns with typical clinical features of Down's syndrome, of which one revealed 48,XXY,+21 GTG-band karyotype. The second newborn died 2 days after its birth, and was clinically diagnosed having Down syndrome. Due to the same clinical features of the twins, the common placenta and amniotic sac, we speculate that they were monozygotics and as a result the second newborn should also be a Klinefelter. The purpose of this report is to present a rare case of possible coincidence of double aneuploidy in newborn twins. A review of the literature showed that double trisomy (48,XXY,+21) in a twin newborn infant has never occurred. PMID:15050879

Calmodulin regulates dimerization, motility, and lipid binding of Leishmania myosin XXI.  

PubMed

Myosin XXI is the only myosin expressed in Leishmania parasites. Although it is assumed that it performs a variety of motile functions, the motor's oligomerization states, cargo-binding, and motility are unknown. Here we show that binding of a single calmodulin causes the motor to adopt a monomeric state and to move actin filaments. In the absence of calmodulin, nonmotile dimers that cross-linked actin filaments were formed. Unexpectedly, structural analysis revealed that the dimerization domains include the calmodulin-binding neck region, essential for the generation of force and movement in myosins. Furthermore, monomeric myosin XXI bound to mixed liposomes, whereas the dimers did not. Lipid-binding sections overlapped with the dimerization domains, but also included a phox-homology domain in the converter region. We propose a mechanism of myosin regulation where dimerization, motility, and lipid binding are regulated by calmodulin. Although myosin-XXI dimers might act as nonmotile actin cross-linkers, the calmodulin-binding monomers might transport lipid cargo in the parasite. PMID:24379364

A comparison of these with observational data for the 1973 December 17 solar flare, obtained by the Naval Research Laboratory's S082A and S082B spectrographs on board Skylab, reveals reasonably good agreement between theory and observation for R 1[= I(242.07 mathop ? limits^c)/I(1354.08 Å)], which provides some support for the accuracy of the atomic data adopted in the line ratio calculations. However, our results for R 2 indicate that the emission feature in flare spectra at 338.06 Å, previously identified as the Fe xxi 2s 22p 2 3 p 1 - 2s 22p 2 1 S line, is not due to this species but may be the Ca v 3p 4 3 p 1 - 3p 33d 3 P 2 transition. The potential of using R 1 as an electron temperature diagnostic for the Fe xxi line emitting regions of cool star coronae, through a combination of Extreme Ultraviolet Explorer and Hubble Space Telescope observations, is briefly discussed.

Uniparental disomy (UPD) for fra(X) in a 47,XXY male  

SciTech Connect

We report a 4-year-old hyperactive, mentally retarded male with 47,XXY and UPD for fra(X). Speech and motor delay were first noted at age 15 months. He has no dysmorphic features, normal ears, hyperextensible joints, small testes, and no history of seizures. His mother has prominent lowest ears, a long midface, anteverted nostrils, hyperextensible joints, malocclusion, and had learning problems in school. Routine chromosome analysis revealed the proband to be 47,XXY. Parental chromosomes were normal in number. The proband was fra(X) positive [30/160 cells, 18%]. No cells had two expressed fra(X)s; however, this may be a function of the low level of expression and the number of cells scored. Maternal cells were also fra(X) positive [19/205, 9.2%]. Southern analysis demonstrated the mother to be heterozygous for a methylated, full mutation (>220 repeats); her normal FMR-1 gene was disproportionately unmethylated. The proband had two fully expanded and methylated FMR-1 genes, one the same size as the maternal gene and the other >620 repeats. RFLP analysis revealed a maternal meiotic II error, the result of which was UPD of the X chromosome.

Ovotesticular disorder of sexual development and a rare 46,XX/47,XXY karyotype.  

PubMed

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.

Communication Strategy of Transboundary Air Pollution Findings in a US-Mexico Border XXI Program Project  

NASA Astrophysics Data System (ADS)

From 1996 to 1997, the US Environmental Protection Agency (EPA) and the Texas Natural Resource Conservation Commission (TNRCC) conducted an air quality study known as the Lower Rio Grande Valley Transboundary Air Pollution Project (TAPP). The study was a US-Mexico Border XXI program project and was developed in response to local community requests on a need for more air quality measurements and concerns about the health impact of local air pollutants; this included concerns about emissions from border-dependent industries in Mexico, known as maquiladoras. The TAPP was a follow-up study to environmental monitoring done by EPA in this area in 1993 and incorporated scientific and community participation in development, review of results, and public presentation of findings. In spite of this, critical remarks were leveled by community activists against the study's preliminary "good news" findings regarding local air quality and the influence of transboundary air pollution. To resolve these criticisms and to refine the findings to address these concerns, analyses included comparisons of daily and near real-time measurements to TNRCC effects screening levels and data from other studies along with wind sector analyses. Reassessment of the data suggested that although regional source emissions occurred and outliers of elevated pollutant levels were found, movement of air pollution across the border did not appear to cause noticeable deterioration of air quality. In spite of limitations stated to the community, the TAPP was presented as establishing a benchmark to assess current and future transboundary air quality in the Valley. The study has application in Border XXI Program or other air quality studies where transboundary transport is a concern since it involved interagency coordination, public involvement, and communication of scientifically sound results for local environmental protection efforts.

Klinefelter's Syndrome, 47,XXY, in Male Systemic Lupus Erythematosus Supports a Gene Dose Effect from the X Chromosome  

PubMed Central

Background Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that predominantly affects women. Despite Klinefelter's syndrome (47,XXY) and SLE coexisting in isolated cases, no association has been established with SLE or any other autoimmune disease. Methods: Sex chromosome genotyping was performed in 981 SLE patients (213 were men). A first group of 843 SLE patients from 378 multiplex families and a second group of 138 men with non-familial SLE were evaluated. Fluorescent in situ hybridization (FISH) and karyotyping in transformed B cell lines enumerated chromosomes for selected cases. Results Of 213 men with SLE, five had Klinefelter's syndrome (or 1 in 43). Four of them were heterozygous at X markers. FISH and karyotyping confirmed Klinefelter’s syndrome in the fifth. An overall rate of 235 47,XXY per 10,000 male SLE patients (95%CI: 77 to 539) was found, a dramatic increase over the known prevalence of Klinefelter's syndrome in an unselected population (17 per 10,000 live male births). Asking men with SLE about fertility was highly sensitive (100%) for Klinefelter’s syndrome. All 768 SLE women were heterozygous at X. Conclusions 47,XXY Klinefelter's syndrome, often subclinical, is increased in men with SLE by ~14-fold, compared to its prevalence in men without SLE. Diagnostic vigilance for 47,XXY males in SLE is warranted. These data are the first to associate Klinefelter's syndrome with an autoimmune disease found predominantly in women. The risk of SLE in Klinefelter's syndrome is predicted to be similar to the risk in normal 46,XX women and ~14-fold higher than in 46,XY men, consistent with SLE susceptibility being partly explained by a X chromosome gene dose effect.

Behavioral and Social Phenotypes in Boys With 47,XYY Syndrome or 47,XXY Klinefelter Syndrome  

PubMed Central

OBJECTIVE: To contrast the behavioral and social phenotypes including a screen for autistic behaviors in boys with 47,XYY syndrome (XYY) or 47,XXY Klinefelter syndrome (KS) and controls and investigate the effect of prenatal diagnosis on the phenotype. METHODS: Patients included 26 boys with 47,XYY, 82 boys with KS, and 50 control boys (ages 4–15 years). Participants and parents completed a physical examination, behavioral questionnaires, and intellectual assessments. RESULTS: Most boys with XYY or KS had Child Behavior Checklist parental ratings within the normal range. On the Child Behavior Checklist, mean problem behaviors t scores were higher in the XYY versus KS groups for the Problem Behavior, Externalizing, Withdrawn, Thought Problems, and Attention Problems subscales. On the Conners’ Parent Rating Scale–Revised, the XYY versus KS group had increased frequency of hyperactive/impulsive symptoms (P < .006). In addition, 50% and 12% of the XYY and KS groups, respectively, had scores >15 for autism screening from the Social Communication Questionnaire. For the boys with KS, prenatal diagnosis was associated with fewer problem behaviors. CONCLUSIONS: A subset of the XYY and KS groups had behavioral difficulties that were more severe in the XYY group. These findings could guide clinical practice and inform patients and parents. Boys diagnosed with XYY or KS should receive a comprehensive psychoeducational evaluation and be screened for learning disabilities, attention-deficit/hyperactivity disorder, and autism spectrum disorders.

Donor-derived 47, XXY in an unrelated cord blood transplant recipient.  

PubMed

A 65-year-old Japanese male with therapy-related myelodysplastic syndrome was admitted for unrelated cord blood transplantation. A cord blood unit from a male donor was obtained from the Japan Cord Blood Bank Network. The patient then received a conditioning regimen consisting of fludarabine, intravenous busulfan, and total body irradiation. Successful engraftment was obtained. The bone marrow examination on day 28 revealed trilineage engraftment, and chimerism analysis by variable number of tandem repeat polymerase chain reaction confirmed complete donor chimerism. At that time, conventional cytogenetics of the bone marrow aspirate showed 20 out of 20 metaphases with the 47, XXY karyotype characteristic of Klinefelter syndrome. Klinefelter syndrome is the most common genetic cause of human male infertility with a reported prevalence of 0.1-0.2% in the general population. In Japan Cord Blood Bank Network, there is no informed consent from parents about the possibility that post-unrelated cord blood transplantation patient evaluation may reveal donor-origin inherited diseases including cytogenetic abnormality. It is desirable to have opportunities in Japan discussing whether parents will be notified of the possibility that post-unrelated cord blood transplantation evaluation may reveal donor-derived illness incidentally.

The coronal FeXXI lambda 1354.094 line in AB Doradus  

NASA Astrophysics Data System (ADS)

The active late-type star AB Doradus was observed in February 1996 with the Goddard High Resolution Spectrograph of the Hubble Space Telescope using the low resolution G140L grating. The observations covered one half of the star's rotation cycle (P = 0.514 d) with 11.5 min time resolution. The strong coronal FeXXI lambda 1354.094 line formed at 107 K was analysed and its emission measure (EM) derived. This EM is much higher than that derived from recent XMM-Newton observations (Güdel et al. 2001), and earlier EXOSAT (Collier Cameron et al. 1988) and ASCA/EUVE (Mewe et al. 1996) data, as well, requiring a variability by a factor of 5. The physical reason for the variability remains unknown, since (outside flares) the observed broad band variability of AB Dor is much smaller. Based on observations with the NASA/ESA Hubble Space telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under the NASA contract NAS 5-26555.

XXI century projections of wind-wave conditions and sea-level rise in the Black sea  

NASA Astrophysics Data System (ADS)

Projection of regional climate changes for XXI century is one of the priorities of EC environmental programme. Potential worsening of the waves' statistics, sea level rise and extreme surges are the principal negative consequences of the climate change for marine environment. That is why the main purpose of this presentation is to discuss the above issue for the Black sea region (with a strong focus to the south-west subregion because the maximum heights of waves exceeding 10 m occur just here) using output of several global coupled models (GCM) for XXI century, wave simulation, long-term observations of sea level and statistical techniques. First of all we tried to choose the best coupled model (s) simulated the Black sea climate change and variability using the control experiments for 20 century (203). The principal result is as follows. There is not one model which is simulating adequately even one atmospheric parameter for all seasons. Therefore we considered (for the climate projection) different outputs form various models. When it was possible we calculated also the ensemble mean projection for the selected model (s) and emission scenarios. To calculate the wave projection we used the output of SWAN model forced by the GCM wind projection for 2010 to 2100. To estimate the sea level rise in XXI century and future surges statistics we extrapolate the observed sea level rise tendencies, statistical relation between wave heights and sea level and wave scenarios. Results show that in general, the climate change in XXI century doesn't lead to the catastrophic change of the Black sea wind-wave statistics including the extreme waves in the S-W Black sea. The typical atmospheric pattern leading to the intense storm in the S-W Black sea is characterized by the persistent anticyclonic area to the North of the Black sea and cyclonic conditions in the Southern Black sea region. Such pressure pattern causes persistent and strong eastern or north-eastern wind which generates the high waves in the S-E Black sea. The climate projections show that the frequency of such atmospheric pattern will not principally increase. The recent probability of the extreme wave height (exceeding 8 to10 m) in the S-W Black sea (~1 occurrence per 10 years) will not be much worse in XXI century. Similar conclusion is true for the storm surges along the Bulgarian coastline. Expected sea level rise in the Black sea basin for XXI century due to regional climate changes is about 2 mm per year (±50%). However, some Black sea subregions (such as Odessa and Varna bay) are characterized by fivefold sea level rise because of the local land subsidence. So, this geomorphologic effect is the most dangerous local consequence for the sustainable development and management of the coastal zone in such subregions. This study was supported by EC project "THESEUS".

Prepubertal unilateral gynecomastia and the presence of 47,XXY mosaicism in breast epithelial cells: a case report.  

PubMed

Breast enlargement in prepubertal boys is a rare condition. This case report describes an otherwise healthy 3-year old non-obese boy who developed a large unilateral cystic breast mass measuring approximately 9 × 6 × 4 cm. The mass was initially treated as a lymphatic malformation, and sclerotherapy with Picibanil (OK-432) was attempted without any detectable effect on size. The mass was later excised. The pathological examination revealed mammary gland tissue suggestive of idiopathic gynecomastia. FISH revealed 47, XXY mosaicism in the abnormal breast epithelial cells, but not in peripheral blood lymphocytes. PMID:23414896

Extensive spectroscopic data for multiply ionized scandium: Sc III to Sc XXI  

NASA Astrophysics Data System (ADS)

Context. Spectroscopic data for scandium is sparse, while an extensive set is needed to introduce this element into stellar opacity calculations and, more importantly, into stellar models dealing with radiative diffusion. Aims: Our goal is to provide extensive energy levels and radiative transitions data for nineteen ionization stages of scandium relevant to stellar interiors, namely from Sc iii to Sc xxi. Methods: We used the FAC code. This code provides ab initio theoretical values for energy levels in jj-coupling and oscillator strengths of all permitted transitions. Detailed correspondences are established with compiled data from the National Institute of Standards and Technology (NIST) database, to locate as much as possible the observed levels and lines at their experimental values and to estimate the quality of our data. Comparison were also made with the spectroscopic data delivered by Kurucz. Results: The theoretical data retained in tables include 21 842 levels and more than two millions transtions. By comparison, the NIST compilation gives a total of 820 levels and 677 gf-values. The good agreement obtained when comparing the new data with those of the NIST compilation demonstrates their quality. This work on scandium shows that the FAC code is efficient in providing spectrocopic data that are unavailable from laboratory analyses but necessary for accurate simulations of stellar plasmas. Full Tables 4-6 and extensive line lists for each ion are only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/538/A52

Electron density determinations of stellar coronae using Fe XXI ndarrow2p (n=3,4,5,6) transitions  

NASA Astrophysics Data System (ADS)

The idea of using L-shell iron spectroscopic information to infer the electron density has become very attractive following the availability of high-resolution data measured by current x-ray observatories. Following suggestions in [1], we developed the n darrow2p line (n=3,4,5,6) intensities in Fe XXI as a diagnostic that is sensitive to densities near 10^13 cm-3 and applied it to Chandra observations of HR1099. HULLAC code predictions of the density sensitivity were checked with the Livermore EBIT-II ion trap for low densities. Checks at high density are in progress at the Princeton NSTX tokamak. For HR1099 we find a density of about 2 to 8 x 10^13 cm-3. This is in the range of 10^12 - 10^13 cm-3 that was determined using the Fe XXI EUV line ratios (102/128 ÅÅobserved with EUVE [2]. This work was performed under the auspice of DOE by UC-LLNL under contract W-7405-Eng-48 and supported by DOE OFES and by NASA SARA grants to LLNL, GSFC, PPPL and Columbia University.\\$[1].

Social attention, affective arousal and empathy in men with Klinefelter syndrome (47,XXY): evidence from eyetracking and skin conductance.  

PubMed

Individuals with an extra X chromosome (Klinefelter syndrome) are at risk for problems in social functioning and have an increased vulnerability for autism traits. In the search for underlying mechanisms driving this increased risk, this study focused on social attention, affective arousal and empathy. Seventeen adults with XXY and 20 non-clinical controls participated in this study. Eyetracking was used to investigate social attention, as expressed in visual scanning patterns in response to the viewing of empathy evoking video clips. Skin conductance levels, reflecting affective arousal, were recorded continuously during the clips as well. Empathic skills, i.e. participants' understanding of own and others' emotions in response to the clips was also assessed. Results showed reduced empathic understanding, decreased visual fixation to the eye region, but increased affective arousal in individuals with Klinefelter syndrome. We conclude that individuals with XXY tend to avoid the eye region. Considering the increased affective arousal, we speculate that this attentional deployment strategy may not be sufficient to successfully downregulate affective hyper-responsivity. As increased affective arousal was related to reduced empathic ability, we hypothesize that own affective responses to social cues play an important role in difficulties in understanding the feelings and intentions of others. This knowledge may help in the identification of risk factors for psychopathology and targets for treatment. PMID:24416272

Model estimations of the Arctic sea ice conditions in XXI century  

NASA Astrophysics Data System (ADS)

Dynamic-thermodynamic sea ice model, developed in AARI is applied for estimations of recent and future sea ice conditions in the Arctic Basin. The model describes sea ice cover in terms of relative areas of level ice, ridges with fixed form, and leads. The main equations of model are stationary impulse balance equation and non-stationary mass balance equation with parameterizations of heat and dynamic processes in level ice, leads and ocean mixed layer. The parameterizations include: quasi-stationary thermodynamic model for level sea ice, Brown parameterization of atmospheric boundary layer, McPhee parameterization of the ocean mixed layer, Kenig-Langlo & Augstein parameterization of incoming longwave radiation, Monin -Obukchov parameterization for stratified atmospheric surface layer, Shine parameterization for shortwave radiation balance, parameterizations of heat processes in leads (similar Ebert and Curry), Flato and Hibler parameterization of internal ice stresses in the framework of cavitating fluid, Hakkinen and Mellor estimations of oceanic heat fluxes in the Barents, Bering and Greenland seas, and some intuitive data about ridge melting. External forcing of the model are: fixed dynamic topography of the Arctic ocean and monthly mean fields for relative humidity, total cloudiness and solid precipitation, and NCEP/NCAR or from different scenarios data about atmospheric surface pressure and surface level air temperature. Numerical experiments with a dynamic-thermodynamic sea ice model under NCEP/NCAR Reanalysis forcing allowed to reproduce the thinning of the sea ice cover in the main part of the Arctic Basin, that had been documented by Rothrock et all (1999), as well as well-know strong decrease of sea ice area in 2007 and 2008. Follow our model estimations the main reason of the sea ice thinning and decline is the changes in atmospheric circulation. The second reason is the increase of atmospheric surface layer temperature. Using as atmospheric forcing the results of prognostic estimations follow scenario A1B from ECHAM5/MPI-OM, HAD CM3 and CCSR/NIES/FRCGC models for period 2000 - 2100 the estimations of sea ice cover had been done. It is shown that despite the strong decrease of sea ice cover area and volume, especially with data from ECHAM5/MPI-OM and CCSR/NIES/FRCGC, numerical experiments with dynamic-thermodynamic model show that under all three scenarios multy-year ice will save in the Canadian Basin up to the end of XXI century.

EUV measurements of Kr XXI–Kr XXXIV and the effect of a magnetic-dipole line on allowed transitions  

NASA Astrophysics Data System (ADS)

We observed and analysed the extreme-ultraviolet spectra of highly charged ions of Kr XXI–Kr XXXIV produced in an electron beam ion trap (EBIT). The beam energies varied between 1.1 and 30 keV, and the wavelengths were observed between 3 and 17.3 nm with uncertainties of ?0.003 nm. Six new lines were identified, and wavelength uncertainties have been improved for twelve additional transitions. It was found that a line intensity ratio for allowed transitions 3s23p–3s23d in Al-like Kr XXIV strongly deviated from predictions based on statistical weighting of the excited levels. Collisional-radiative modelling showed that this effect, which is due to the magnetic-dipole transition within the ground configuration 3s23p, offers sensitive diagnostics of electron density in the regime of interest to fusion tokamaks, EBITs, and other low-density plasmas.

PREFACE: 21st Latin American Symposium on Solid State Physics (SLAFES XXI)  

NASA Astrophysics Data System (ADS)

The Latin American Symposium on Solid State Physics (SLAFES) started in Caracas-Venezuela, and over time the symposia have taken place in 9 different Latin American countries. The last five events took place in Mérida-Venezuela (2002), Havana-Cuba (2004), Puebla-Mexico (2006), Puerto Iguazú-Argentina (2008) and Maragogi-Brazil (2011). During the last years, in the different SLAFES editions, the aim has been to bring together researches from Latina America and invite renowned scientists from around the world to a unique forum to discuss the latest developments regarding Solid state Physics. The 21st Latin American Symposium on Solid State Physics (SLAFES XXI) was held in Villa de Leyva-Colombia, from September 30 to October 04, 2013.

Increased basal and pulsatile secretion of FSH and LH in young men with 47,XXY or 46,XX karyotypes  

PubMed Central

Objective The regulation of normal sexual maturation and reproductive function is dependent on a precise hormonal regulation at hypothalamic, pituitary, and gonadal levels. The aim of this study was to investigate the neuroendocrine integrity of the pituitary-gonadal axis in patients with primary testicular failure due to supernumerary X chromosomes. Design Cross-sectional study. Methods In this study, 7 untreated patients with primary gonadal insufficiency due to SRY-positive 46,XX (n=4) and 46,XXY karyotypes (n=3) aged 18.8 years and 25 age-matched healthy controls participated. Reproductive hormones, testicular size, and overnight LH and FSH serum profiles and overnight urine LH and FSH excretion were determined. Results Basal LH and FSH secretion was elevated 6.3- and 25.4-fold respectively in the patients and the amount of LH and FSH secreted per burst were 2.0- and 6.6-fold elevated. We found significantly more LH but not FSH peaks per 24 h, as estimated by the Weibull ? analysis. There was no difference between approximate entropy ratios or Weibull ? analyses indicating comparable orderliness and regularity of LH and FSH secretion. Overnight urinary LH and FSH excretion was significantly elevated in patients compared with controls and correlated significantly with calculated total overnight LH and FSH secretion respectively, thus validating deconvolution. Conclusion In this group of patients with severe hypergonadotropic hypogonadism due to a supernumerary X chromosome, higher basal, pulsatile, and total LH and FSH secretion were associated with significantly more LH peaks per 24 h in comparison with healthy controls. Thus, our data indicate that in patients with Klinefelter syndrome and XX male karyotypes the entire hypothalamic-pituitary-gonadal axis has undergone functional changes.

Evolution in Intensity and Frequency of Extreme Events of Precipitation in Northeast Region and Brazilian Amazon in XXI Century  

NASA Astrophysics Data System (ADS)

The aim of this research was evaluate changes in frequency and intensity of extreme events of precipitation in Brazilian Amazon and Northeast Region, doubling CO2 concentration in agreement of IPCC A2 emissions scenarios (Nakicenovic et al., 2001). For this evaluation was used ETA model (Chou et al., 2011), forced with CCSM3 Global model data (Meehl, 2006) to run 4 experiments, only for January, February and March: 1980-1990, 2000-2010, 2040-2050 and 2090-2100. Using the first decade as reference (1980-1990), was evaluated changes occurred in following decades, with a methodology to classify extremes events adapted from Frich (2002) and Gao (2006). Higher was the class, more intense is the event. An increase of 25% was observed in total precipitation in Brazilian Amazon for the end of XXI century and 12% for extreme events type 1, 9% for events type 2 and 10% for type 3. By the other hand, a 17% decrease of precipitation in Brazilian Northeast was observed, and a pronounced decay of 24% and 15% in extreme events contribution type 1 and 2 to total amount of precipitation, respectively. The difference between total normal type events was positive in this three decades compared with reference decade 1980-1990, varying positively from 4 to 6 thousand events included in normality by decade, these events was decreased in your majority of Class 1 events, which presented a decay of at least 3.500 events by each decade. This suggests an intensification of extreme events, considering that the amount of precipitation by class increased, and the number of events by class decreased. To Northeast region, an increasing in 9% of contribution to events type 3 class was observed, as well as in the frequency of this type of events (about of 700 more events). Major decreasing in number of classes extreme events occur in 2000-2010, to classes 1 and 3, with 7,2 and 5,6%, and by the end of century in class 3, with 4,5%. For the three analyzed decades a total decrease of 8.400 events was accounted. This first results support an increase in occurrence of determined extreme events classes/types of precipitation, but also an increase of precipitation in raining seasons in Amazon region, as well as an increase in the intensity of dry season in Northeast region.

Atomic data from the Iron Project. XLV. Relativistic transition probabilities for carbon-like Ar XIII and Fe XXI using Breit-Pauli R-matrix method  

NASA Astrophysics Data System (ADS)

The Breit-Pauli R-matrix method developed under the Iron Project has been used to obtain extensive sets of oscillator strengths and transition probabilities for dipole allowed and intercombination fine structure transitions in carbon like ions, Ar XIII and Fe XXI. The complete set consists of 1274 fine structure bound energy levels and 198 259 oscillator strengths for Ar XIII, and 1611 bound levels and 300 079 oscillator strengths for Fe XXI. These correspond to levels of total angular momenta of 0 <= J <= 7 of even and odd parities formed from total spin of 2S+1=5, 3, 1, and orbital angular momenta 0 <= L<= 9 with n<= 10, 0 <= l<= 9 for each ion. The relativistic effects are included in the Breit-Pauli approximation. The close coupling wavefunction expansion for each ion is represented by the lowest 15 fine structure levels of target configurations, 2s22p, 2s2p2 and 2p3. The energy levels are identified spectroscopically using a newly developed identification procedure. The procedure also makes a correspondence between the fine structure energy levels and LS terms. This provides the check for completeness of the calculated levels. Comparison is made of the present energies and the f-values with the available observed and theoretical values. Present transition probabilities agree very well with the relativistic atomic structure calculations of Mendoza et al. for the intercombination transitions, 2s2p3(5S{o}_2) - 2s22p2(3P1,2,1D_2). This further indicates that the importance of the neglected Breit interaction decreases with ion charge and constrains the uncertainty in the present calculations to within 15% even for the weak transitions.

A new neuropsychology for the XXI century.  

PubMed

Regardless of the significant interest in comparing neuropsychological syndromes across cultures, little interest is observed in comparing these syndromes across time. Most of the neuropsychological syndromes were described during the late nineteenth and early twentieth century (e.g., aphasia, alexia, agraphia, acalculia, etc.). However, living conditions have so dramatically changed during the last 100 years that those classical neuropsychological syndromes have to be re-stated and reconsidered; eventually, new syndromes could be proposed. In this paper, an analysis of the impact of the new living conditions in spoken language, written language, numerical abilities, memory, spatial orientation, people recognition, and executive functions is presented. It is concluded that it is time to re-analyze and re-interpret the classical neuropsychological syndromes; and develop new assessment procedures, more in accordance with the twenty-first century living conditions.

Sobre el estado evolutivo de ? Pictoris  

NASA Astrophysics Data System (ADS)

Desde el descubrimiento de fuertes excesos infrarrojos en ? Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. ? Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a ?Pic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en ? Pic indica edades avanzadas para ? Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para ? Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

Sperm segregation patterns by fluorescence in situ hybridization studies of a 46,XY,t(2;6) heterozygote giving rise to a rare triploid product of conception with a 69,XXY,t(2;6)(p12;q24)der(6)t(2;6)(p12;q24)pat karyotype.  

PubMed

A blighted ovum diagnosed initially by ultrasound was determined to be a partial hydatidiform mole with a 69,XXY,t(2;6)(p12;q24)der(6)t(2;6)(p12;q24)pat karyotype by cytogenetic analysis. The triploid state arose through dispermy in which both spermatozoa carried rearranged chromosomes, one carrying a balanced translocation through alternate segregation and the other an unbalanced derivative chromosome 6 through adjacent 1 segregation. Segregation analysis of 7,000 spermatozoa from the father was performed with a three-color fluorescence in situ hybridization (FISH) protocol using alpha-satellite 6, telomeric 2p, and telomeric 6q probes. Segregation frequencies of normal and balanced products (alternate segregation), adjacent 1, adjacent 2, and 3:1 were 49.9%, 42.4%, 2.5%, and 4.2%, respectively. The high percentage of alternate segregation is consistent with the knowledge of their preferential outcome. However, the high incidence of adjacent 1 sperm highlights the abnormality risk. Alternate and adjacent 1 segregations (92.3%) accounted for the observed rearranged chromosomes in the triploid. The most viable imbalanced combination would be the one carrying the der(6) chromosome, but since the unbalanced segment comprises 3.6% of the haploid autosomal length (HAL), no risk of a viable imbalanced offspring is indicated. However, an increased likelihood of recurrent miscarriages is likely, and this is confirmed by the couple's two earlier miscarriages. Sperm segregation patterns of translocation carriers determined by FISH can help in ascertaining expected and unexpected karyotypes. The high frequency of adjacent 1 products shows that the presence of the additional derivative chromosome in the partial mole, though rare in occurrence, should be less surprising. PMID:12567417

Sobre a largura da última superfície de espalhamento  

NASA Astrophysics Data System (ADS)

De acordo com o modelo do "Big-Bang", no universo primordial a matéria estava em equilíbrio térmico com a radiação. Com a expansão a temperatura da radiação cai. Quando a temperatura chega em torno dos 4.000K, os espalhamentos diminuem, começando a recombinação dos prótons e elétrons em Hidrogênio neutro (era conhecida como da recombinação). Ao final da recombinação, os fótons se propagam livremente sofrendo, em princípio, somente os efeitos do "redshift" cosmológico. Esses fótons nos alcançam hoje como a radiação cósmica de fundo (RCF), e parecem vir de uma superfície esférica ao nosso redor, tal que o raio dela é a distância que ele viajou desde seu último espalhamento na época da recombinação. Naturalmente, esse processo não ocorreu abruptamente, implicando na existência de uma largura no espaço dos "redshifts" que deve depender do modelo cosmológico específico e dos processos físicos considerados. Neste trabalho analisamos os efeitos de diferentes modelos - a saber, aqueles com decaimento do vácuo L(t), criação de matéria, quintessência e gás de Chaplygin - sobre a última superfície de espalhamento da RCF, em particular sua largura e a função visibilidade, que determina a probabilidade de um fóton ter tido seu último espalhamento num "redshift" z. No caso particular dos modelos com decaimento do vácuo, existe uma forte dependência da função visibilidade com L(t). Tais efeitos poderão ser testados através da análise dos resultados de experimentos mais precisos que estão atualmente em andamento, como por exemplo, o WMAP.

[Clinical research XXI. From the clinical judgment to survival analysis].  

PubMed

Decision making in health care implies knowledge of the clinical course of the disease. Knowing the course allows us to estimate the likelihood of occurrence of a phenomenon at a given time or its duration. Within the statistical models that allow us to have a summary measure to estimate the time of occurrence of a phenomenon in a given population are the linear regression (the outcome variable is continuous and normally distributed -time to the occurrence of the event-), logistic regression (outcome variable is dichotomous, and it is evaluated at one single interval), and survival curves (outcome event is dichotomous, and it can be evaluated at multiple intervals). The first reference we have of this type of analysis is the work of the astronomer Edmond Halley, an English physicist and mathematician, famous for the calculation of the appearance of the comet orbit, recognized as the first periodic comet (1P/Halley's Comet). Halley also contributed in the area of health to estimate the mortality rate for a Polish population. The survival curve allows us to estimate the probability of an event occurring at different intervals. Also, it leds us to estimate the median survival time of any phenomenon of interest (although the used term is survival, the outcome does not need to be death, it may be the occurrence of any other event).

The 21st International Conference on Spectral Line Shapes, ICSLS, was held in the historic main building of St Petersburg State University (St. Petersburg, Russia) on 3-9 June 2012. The event continued the tradition started in 1978 in Meudon Observatory in Paris. Representatives of line shape physics have since met every two years in different locations in Europe and North America. The most recent events were held in St John's, Newfoundland, Canada (2010), Valladolid, Spain (2008), and Auburn, AL (USA). Traditionally, the conferences consider experimental and theoretical issues of studying spectral line shapes, diagnostic utilization of spectral line profiles observed in absorption, emission or scattering of electromagnetic radiation by atoms, molecules, and clusters in different environments, including neutral environments, laboratory low and fusion plasmas, astrophysical conditions, and planetary atmospheres. The Conference was attended by over 100 professionals from Europe, Asia, America, Africa and New Zealand. The conference program was put together in such a way so as to exclude any parallel sessions. Five afternoon sessions featured 19 invited talks and 20 oral contributions, and two evening sessions offered 61 poster presentations, including post-deadline posters. This setup allowed for a relaxed and unhurried discussion of results and facilitated productive networking. The invited talks were selected by recommendation of members of the International Scientific Committee. The Organizers would like to thank all the members of the International Scientific Committee for their proposals on the agenda and their valuable advice. When considering candidates for oral contributions, the organizers took into account the suggestions and preferences of potential conference participants. When selecting the theses of poster presentations, the organizers focused on the topics in line with the theme of the conference and studies with well-formulated results. It must be noted that this year's conference included a noticeably larger number of reports on astrophysical applications and physics of planetary atmospheres. Another significant trend was related to a new area of inquiry: low temperature spectra, near-surface processes, and control and management of new technological processes. There were more presentations on elementary processes during the formation of spectral lines. Most of the presented studies were included in the Conference Proceedings publication. For the first time ever the proceedings will be published as a volume of Journal of Physics: Conference Series, published by the Institute of Physics (UK), making it possible to access the materials of the conference online. All published studies underwent peer review. The organizers would like to thank all the reviewers who found time to review the submissions against a very tight deadline during the summer. Professor N G Skvortsov, Vice-Rector for Research of St Petersburg State University, opened the conference. His speech was followed by a brief welcome message from Professor A Devdariani of St Petersburg State University, Deputy Chair of the Organizing Committee. An informal welcome party was held before the opening session. The cultural program of the event included various sightseeing tours, and a hydrofoil boat ride to the fountain city of Peterhof, where the delegates toured the park and attended a conference dinner. Organizers would like to express their appreciation to St Petersburg musicians, P Laul and D Kouzov for an excellent classical music concert. The conference included a meeting of the International Scientific Committee the minutes of the event are included in this volume (article number 011004). Most importantly, the next meeting, 22nd ICSLS, has been scheduled for 2014 in The Center for Laser Applications, The University of Tennessee Space Institute, US. Professor Christian Parriger will coordinate the organization. Organizers of the St Petersburg Conference would like to wish him and his colleagues every success for the next conference in Tennessee.

Women's role in the Engineering career: situation in the XXI century  

NASA Astrophysics Data System (ADS)

There is no doubt that women education and attendance to university have facilitated their access to almost all the working sectors. At the same time, it has point out a break point between the traditional scenario and the actual reality, how achievements have been obtained thanks to day by day fight, little steps and advances give impulse to women to a full participation in the working area, diversifying her role in different fields and occupying in work market different roles that recently were exclusive for men. For example: army, truck drivers, miners and airplane pilots among others. However, not everything are lights in this reflection with an optimistic touch, there are shadows too, opposition, obstacles, impediments and difficulties in the society or in women herself that have to be avoided when they incorporate in different labour markets. The difficulties that women have been overcome and the gender inequality that still can be found, even in occidental societies, are something that concerns to all of us. We believe that it is necessary centuries to overcome certain aspects that, in some way, are impregnated in the society, life style, rules of conduct, culture, or simply learned by the people that are really difficult not only to elude them as to avoid them. Throughout this work some examples will be shown that corroborate this comment. This subject is wide, complex and difficult. For this reason, we will put a limit on it and we will focus on the Spanish society as a part of the western advanced societies. With regard to the working area, we will delimited this study to the engineering careers showing some allusive numbers, actual university studies in this field and related them to earlier decades. In this way, a comparative analysis on the evolution of this scenario can be established. There are many papers and manuscripts that talk about different aspects in female success, such as women in sport, highly gifted and women, etc. For this reason we are going to centre our work on engineering at different places: corporations, institutions, etc where women play a role in the work market. Although it is not easy "gender roles" change if the internal structure and perception of the society, people's descriptive believes or the respective societies that support it don't do it, it has a certain relation with the stereotypes and prejudices. The origin of the preconceived opinion against women holding certain roles that traditionally were for males are found in the inconsistency perception among the characteristics requires for that role and the well assimilated believes about how are women. In this work, we will show some data related with women performance in different studies and different work markets in which there is an evident quantitative difference between men and women.

Demography of peoples of the Russian North in the beginning of XXI century.  

PubMed

Against the background of natural decline in population of all Russia, in particular, the Russians, the demographic situation of peoples of the North is at times considered as "moderately optimistic". In this case the growth of their number serves according to last population census, as a decisive factor. Contrary to the above, many researchers in different regions and among different peoples of the North speak about economic decline and growth of unemployment, an impoverishment of indigenous northerners, their high morbidity and death rate and estimate the demographic situation as "catastrophic". The criterion thus becomes the social crisis in northern settlements. Estimating the demographic situation it is necessary to lean on demographic criteria as such. But the dynamics of the number of the North's peoples, i.e. the sole result of the population census reflecting "well-being", is not such a pure demographic criterion. It was, as we have shown, investigating the data of four population censuses of the USSR (1959,1970,1979,1989), determined in many respects not only, and not at all so much by their demographic movement (i.e. birth rate and death rate), but rather by ethnic (assimilation) processes, and sometimes simply by discrepancies in the census work. While in 1959-89 peoples of the North used to be assimilated by other peoples, in 1989-2002 a reverse tendency became pronounced among some of these peoples. Over a quarter of an inter-census growth was due to ethnic assimilation among six peoples (the Khants, Mansis, Itelmens, Selkups, Kets and Saami). The comparison of inter-census living out among peoples of the North demonstrates that the death rate among them is considerably higher, than the very high death rate of the entire population of Russia. The actual demographic parameters provide evidence for obviously unfavorable tendencies. There was a sharp decrease in birth rate (the overall ratio has decreased from 30% during the 5-year period before the 1989 census up to 18% in 1999-2002). Death rate has grown. Though the overall ratio is lower, than for the whole population of Russia, it is explained by the young age structure of peoples of the North (only 6 % are older than 60, and 18 %--are older than 45; in Russia--18% and 37% accordingly). The average life expectancy (a more adequate yardstick to measure mortality) among peoples of the North is more than 10 years less than the average Russian one. It is less, than among other indigenous peoples of the North (in Scandinavia, Alaska, Canada and Greenland). The share of deaths due to external reasons (accidents, poisonings, suicides and homicides) is enormous; among peoples of the Tyumen North it makes 37% of all the deaths, and in Russia as a whole it is 14% (though the Russian figure itself is far too high by international standards). It is exactly the death rate that determines the nature of the demographic situation. No ultrahigh birth rate in the modern world can serve as an indicator of "well-being" (otherwise the demographically safe region would be Africa south of Sahara). Therefore, certainly we have to define the demographic condition of peoples of the North as a crisis. And further decrease in birth rate with such a high death rate can surely lead to their factual depopulation. Numerical smallness makes them most vulnerable in this respect, while in fact the prospect of vanishing worries much more numerous peoples just as well. PMID:17929647

Geophysical variables and behavior: XXI. Geomagnetic variation as possible enhancement stimuli for UFO reports preceding earthtremors.  

PubMed

The contribution of geomagnetic variation to the occurrence of UFORs (reports of UFOs) within the New Madrid States during the 6-mo. increments before increases in the numbers of IV-V or less intensity earthquakes within the central USA was determined. Although statistically significant zero-order correlations existed between measures of earthquakes, UFORs and geomagnetic variability, the association between the latter two deteriorated markedly when their shared variance with earthquakes was held constant. These outcomes are compatible with the hypothesis that geomagnetic variability (or phenomena associated with it) may enhance UFORs but only if tectonic stress and strain are increasing within the region.

Deep-space radiation exposure analysis for solar cycle XXI (1975-1986)  

NASA Technical Reports Server (NTRS)

Ionizing radiation exposures and associated dosimetric quantities are evaluated for the 11-year solar cycle ending in 1986. Solar flare fluences for the 55 largest flares occurring during the cycle are superimposed on the Galactic cosmic ray flux. Published summaries of flare data from the Interplanetary Monitoring Platform (IMP)-7 and IMP-8 satellites are used that include flares whose integrated fluences are greater than 10 to the 7th protons/sq cm for energies in excess of 10 MeV. A standard cosmic ray environment model for ion flux values at solar minimum and maximum is invoked with an assumed sinusoidal variation between the lower and upper limits. The radiation shielding analysis is carried out for equivalent water-shield thicknesses between 2 and 15 g/sq cm. Results are expressed in terms of cumulative incurred dose equivalents for deep-space missions lasting between 3 months and 3 years. It was found that medium-to-large flare contributions are of greatest importance for the shorter term missions, while the Galactic component dominates for the longer duration missions.

[Reflexions about the curricula at the faculty of medicine in the XXI century].  

PubMed

In this paper we review the main medical programs from the Universidad Nacional Autonoma de Mexico (UNAM) faculty of medicine in the first seventy-five years of twentieth century. We have selected those instances that are representative of special moments in the development of Mexican medical knowledge, and also corresponding to the need to prepare medical students in view of social demands. The first programs are those of Ignacio Chavez in 1934, concerned mainly with the introduction into the curricula of medical specialties such as cardiology or neurology. After those, the 1956 and 1960 programs are mentioned and briefly analyzed; both were founded on the concern to develop a clinical reasoning in the student. Finally, the 1974 Integral General Medicine Program directed its interest to social and environmental themes. PMID:21527967

Some seasonal characteristics in atmospheric methane concentration in the beginning of the XXI century  

NASA Astrophysics Data System (ADS)

Global average value of atmospheric methane concentrations have been increasing during the XX century, but this growth nearly stopped with the beginning of the 2000th. Such "stable" situation is the proper time for studying the seasonal cycle and extreme changes of air methane concentration. One of the most interesting periods for such investigations is autumn and winter 2006/07 [1] when a number of weather abnormalities (warm air temperature up to above 0°C, almost permanent cloudiness and absence of snow cover, and so on) in Moscow region created very specific conditions for air methane existence. Temporal variations in air methane concentration within the Moscow city have been studied using the data of observations at 12 stations of Moscow municipal environmental monitoring agency "Mosecomonitoring" in 2004-2008 [2]. It was found that near-surface air concentration of methane was much higher this time than few years before and after. The values of cold season methane concentrations in Moscow region have been compared with similar data measured in the North of Kola Peninsula (at WMO GAW station "Teriberka"), in the Sankt Petersburg region (the two stations of Roshydromet), in Finland and Hungary (the stations of NOAA GMD Carbon Cycle Sampling Network). Winter maxima (more or less) of methane concentrations were revealed almost each year at all these stations, but not everywhere they were simultaneous and as high as those had been found in Moscow. The reasons of winter 2006/07 high methane concentrations in Moscow and other regions of Northern Eurasia may be special weather conditions which could cause both decrease of air methane sinks and increase of methane emissions from natural and anthropogenic sources. Perhaps, the late growth of global atmospheric methane concentration after 2007 [3] was partly produced by those seasonal anomalies in the Northern Hemisphere. References: 1. E. Fedorova, A.

Wetlands and methane emission in the XXI century: RCM-based projection for Northern Eurasia  

NASA Astrophysics Data System (ADS)

Russia has largest resources of wetlands in the world. Marshes and forested swamps occupy up to 20% of country's territory. The role of wetlands in the natural processes and human society is multifunctional: from providing wildlife habitat and biodiversity to determining water filtration and runoff control. Wetland is an important agent in the global cycling of greenhouse gases. Their exchanges with the atmosphere affects to the regional and global climates thus represent an essential component of environment. In this study the changes in the spatial distributions of wetlands and methane emission are evaluated using the output from MGO GCM/RCM future climate projection. The calculations were performed for the late 20th century (1981-2000) and mid 21st century (2041-2060) under IPCC A2 GHG/aerosols emission scenario. Several characteristics including moisture coefficient and water table have been analysed in order to describe wetland distribution across Eurasia. It has been found that there is a considerable uncertainty in distributions of the analysed characteristics that complicates wetland identification. The water table depth has been adopted to approximate observed distribution of wetlands. As projected by the regional climate model for the mid 21st century the wetland area will expand, notably in May and September and shrink in summer. Evaluated are methane emissions for the late 20th century over wetlands and its possible changes by the mid 21st century. According to RCM projection the methane emission will likely increase in the forthcoming 50 years due to climate warming by approximately 30%. Modeling deficiencies in the wetland distributions and methane emission calculations are discussed. An attention in the analysis is also given to the expected changes in the methane emission potential due to taliks and lakes.

NASA Technical Reports Server (NTRS)

Major amino acids released by hydrolysis of acidic and basic HCN oligomers are identified by chromatography as Gly, Asp, and diaminosuccinic acid. Smaller amounts of Ala, Ile and alpha-aminoisobutyric acid are also detected. The amino acids released did not change appreciably when the hydrolysis medium was changed from neutral to acidic or basic. The presence of both meso and d, l-diaminosuccinic acids was established by paper chromatography and on an amino acid analyzer.

Currently worldwide, the transfusion of blood components cannot be done without residual risks, as compared to those countries with a high human development index, mostly in Europe, that have blood donation systems based on 100% repeat volunteer donors and use molecular biology techniques in screening for infectious diseases. In Latin America and the Caribbean countries, prevention of transfusion-transmissible diseases requires special and different strategies due to several factors: the high prevalence of replacement donors, their specific geographical location, climate, genetic, and sociocultural status of the population make them vulnerable to endemic diseases such as dengue, malaria, and Chagas disease. Thus it is necessary to create local approaches to increase blood safety and achieve the goals set by the Pan American Health Organization. PMID:24481434

Prevalence and natural history of Graves' orbitopathy in the XXI century.  

PubMed

Graves' orbitopathy (GO) is an autoimmune disorder and the main extrathyroidal expression of Graves' disease. There is a spectrum of ocular involvement in Graves' disease, from complete absence of symptoms and signs to sight-threatening conditions. The prevalence of GO varies in different published series of Graves' patients, due to confounding factors (new diagnosis vs long-lasting disease, way of defining and assessing ocular involvement, treatment of hyperthyroidism with potentially GO-modifying treatments, such as radioiodine). Recent studies, however, suggest that most Graves' patients have mild or no GO at presentation, while moderate-to-severe GO is rare, and sight-threatening GO (mostly due to dysthyroid optic neuropathy) is exceptional in non-tertiary referral centers. The natural course of GO is incompletely defined, particularly in patients with moderate- to-severe GO, because these patients require prompt and disease-modifying therapies for orbital disease. In patients with mild GO at presentation, progression to severe forms is rare, while partial or complete remission is frequent. Progression of pre-existing GO or de novo occurrence of GO is more likely in smokers. There seems to be a trend towards a decline in progression of GO, possibly due to a better control of risk factors (cigarette smoking, thyroid dysfunction, etc.) and a closer interaction between endocrinologists and ophthalmologists allowing an improved integrated management of thyroid and orbital disease.

Forest- and agroclimatic potential in the Altai-Sayan ecoregion under climate change during the XXI century  

NASA Astrophysics Data System (ADS)

The Altai Sayan ecoregion (ASE), central Asia, is located in Russia, Mongolia, China and Kazakhstan, within the window 80-102° E and 42-57° N, north of the territory of Tibet. The ASE is a territory with a great variety of landscapes observed at a short distance: from nival and tundra landscapes at highlands, to taiga (dark-needled and light-needled) and subtaiga at middle elevations, to steppes at lower elevations. This southern part of Siberia is known as having a high agroclimatic potential due to favorable climatic and soil resources. Crops of food, forage, and biofuels primarily reside in steppe and forest-steppe zones and are resistant to frequent droughts and the cold climate. Regional studies over the Altai-Sayan ecoregion have already registered a change in climate at the end of the 20th century: January temperatures increased 1-2°C and July temperatures increased 0.7-1.5°C over the last 50 years in the northern portion of ASE; in the southern, more continental portion of ASE, both January and July temperature increased two times greater, 2-4°C and 1.4-3.2°C,0 respectively. Our goal was to model how mountain vegetation in ASE may be altered in a changing climate through the century to the year 2080 and if the agroclimatic potential in the lowlands of ASE may benefit from climate change. We used our montane bioclimatic vegetation model (MontBioCliM) to predict the future vegetation distribution, coupling MontBioCliM with the HadCM3 A2 and B1 climate change scenarios for 2020, 2050, and 2080. MontBioCliM is an envelope-type model that predicts a vegetation type from three climatic indices: growing degree days, base 5C; negative degree days below 0°C; and annual moisture index (a ratio between growing degree days and annual precipitation). Our model runs indicated that by 2080, forest habitats would decrease from 52% to 48% according to the moderate scenario B1 and from 52% to 38% according the harsh A2 scenario. In a warmer climate, grasslands better adapted to hot and dry climates would replace forest which may not be regenerate because of an increased potential for severe and large fires. At the expense of forests, more potential agricultural lands were modeled to appear in new forest-steppe and steppe habitats in foothills and lowlands in ASE. These lands might become suitable for growing traditional crops and introducing new crops. Bioclimatic models determining crop range and regression models determining crop yields were constructed and applied to the above climate change scenarios. Crops were predicted to extend in size and to 2-fold increase. However, due to shortage of water in the future dry climate crops would necessitate irrigation. A new agroclimatic potential of the Altai-Sayan ecoregion was predicted to evolve as climate changes.

Interdisciplinary Study for Knowledge and Dating of the San Francesco Convent in Stampace, Cagliari - Italy Xiii-Xxi Century)  

NASA Astrophysics Data System (ADS)

The Franciscan monastery, situated in the historic center of Cagliari (Sardinia), was founded in the thirteenth century, and transformed during the later centuries, up to the present day. The complexity of the case and the lack of objective data about its history has led us to carry out an interdisciplinary inquiry, in order to achieve a better knowledge of the building, preliminary for the drafting of a restoration project that respects all the signs that the time left. Starting from a deep examination of the indirect sources, turned out to be incomplete, the investigation continued with the execution of a survey with laser scanner and with the characterization of materials and related diseases of degradation. For the laser scanner survey we used a Faro Focus 3D, versatile and lightweight instrument that allows to perform scans with high speed point acquisition and high accuracy. For data elaboration we used the JRC 3D Reconstructor Software by the Gexcel srl. The characterization of the materials was performed on a reasoned sampling of natural and artificial materials, referring to masonry, interstitial mortars and plasters, carried out at strategic points, representative of the various phases of the construction. The samples were studied through mineralogical-petrographic methods with instrumental techniques for the analysis of component materials (OM, X-Ray diffraction). The data obtained, crossed with the results of the reconstruction of historical maps, of the examination of masonry techniques and of the analysis of pattern elements (arches, vaults, decorative elements), have facilitated stratigraphic analysis and helped to advance chronological reasoned hypothesis referring to the building. Besides, an interdisciplinary approach for the study of cultural heritage is very important to define a proper restoration and conservation intervention.

THE ANGLO-AUSTRALIAN PLANET SEARCH. XXI. A GAS-GIANT PLANET IN A ONE YEAR ORBIT AND THE HABITABILITY OF GAS-GIANT SATELLITES  

SciTech Connect

We have detected the Doppler signature of a gas-giant exoplanet orbiting the star HD 38283, in an eccentric orbit with a period of almost exactly one year (P = 363.2 {+-} 1.6 d, m sin i = 0.34 {+-} 0.02 M{sub Jup}, e = 0.41 {+-} 0.16). The detection of a planet with period very close to one year critically relied on year-round observation of this circumpolar star. Discovering a planet in a 1 AU orbit around a G dwarf star has prompted us to look more closely at the question of the habitability of the satellites of such planets. Regular satellites orbit all the giant planets in our solar system, suggesting that their formation is a natural by-product of the planet formation process. There is no reason for exomoon formation not to be similarly likely in exoplanetary systems. Moreover, our current understanding of that formation process does not preclude satellite formation in systems where gas giants undergo migration from their formation locations into the terrestrial planet habitable zone. Indeed, regular satellite formation and Type II migration are both linked to the clearing of a gap in the protoplanetary disk by a planet, and so may be inextricably linked. Migration would also multiply the chances of capturing both irregular satellites and Trojan companions sufficiently massive to be habitable. The habitability of such exomoons and exo-Trojans will critically depend on their mass, whether or not they host a magnetosphere, and (for the exomoon case) their orbital radius around the host exoplanet.

[The economic crisis at the beginning of the XXI century and mortality in Spain. Trend and impact on social inequalities. SESPAS Report 2014].  

PubMed

This study aimed to assess the impact of the current economic crisis on mortality trends in Spain and its effect on social inequalities in mortality in Andalusia. We used data from vital statistics and the Population Register for 1999 to 2011, as provided by the Spanish Institute of Statistics, to estimate general and sex- and age-specific mortality rates. The Longitudinal Database of the Andalusian Population (2001 census cohort) was used to estimate general mortality rates and ratios by educational level. The annual percentages of change and trends were calculated using Joinpoint regressions. No significant change in the mortality trend was observed in Spain from 2008 onward. A downward trend after 1999 was confirmed for all causes and both sexes, with the exception of nervous system-related diseases. The reduction in mortality due to traffic accidents accelerated after 2003, while the negative trend in suicide was unchanged throughout the period studied. In Andalusia, social inequalities in mortality have increased among men since the beginning of the crisis, mainly due to a more intense reduction in mortality among persons with a higher educational level. Among women, no changes were observed in the pattern of inequality. PMID:24612790

Tabanidae (Diptera) of Amaz?nia XXI. Descriptions of Elephantotus gen. n. and E. tracuateuensis sp. n. (Diachlorini) from the Brazilian coast  

PubMed Central

Abstract Elephantotus, a new genus of Tabanidae from the Amazon coast, Brazil, is described based on a new species E. tracuateuensis. Five females were collected in Pará State, and a male in Maranhão State. Arguments are presented for separating the new genus from Dasybasis, as well as the possibility of its occurrence being related to the nesting sites of coastal birds. The new species is characterized by its large size (x = 2.15 cm, n = 5 females), glabrous eyes, reddish-brown tegument, light brown frontal callus not touching the edges of the eyes, extending up to the vertex that has traces of ocelli, basal plate of the antennal flagellum with obtuse angle, without a tooth or spine, wings hyaline, with brown basal cells, without appendix in the fork of vein R4+5, and genital furca wide with extended flaps.

The ATLAS3D project - XXI. Correlations between gradients of local escape velocity and stellar populations in early-type galaxies  

NASA Astrophysics Data System (ADS)

We explore the connection between the local escape velocity, Vesc, and the stellar population properties in the ATLAS3D survey, a complete, volume-limited sample of nearby early-type galaxies. We make use of ugriz photometry to construct Multi-Gaussian Expansion models of the surface brightnesses of our galaxies. We are able to fit the full range of surface brightness profiles found in our sample, and in addition we reproduce the results of state-of-the-art photometry in the literature with residuals of 0.04 mag. We utilize these photometric models and SAURON integral-field spectroscopy, combined with Jeans dynamical modelling, to determine the local Vesc derived from the surface brightness. We find that the local Vesc is tightly correlated with the Mg b and Fe5015 line strengths and optical colours, and anti-correlated with the H? line strength. In the case of the Mg b and colour-Vesc relations we find that the relation within individual galaxies follows the global relation between different galaxies. We intentionally ignored any uncertain contribution due to dark matter since we are seeking an empirical description of stellar population gradients in early-type galaxies that is ideal for quantitative comparison with model predictions. We also make use of single stellar population (SSP) modelling to transform our line strength index measurements into the SSP-equivalent parameters age (t), metallicity ([Z/H]) and ?-enhancement [?/Fe]. The residuals from the relation are correlated with age, [?/Fe], molecular gas mass and local environmental density. We identify a population of galaxies that occur only at low Vesc that exhibit negative gradients in the Mg b- and Colour-Vesc relations. These galaxies typically have young central stellar populations and contain significant amounts of molecular gas and dust. Combining these results with N-body simulations of binary mergers we use the Mg b-Vesc relation to constrain the possible number of dry mergers experienced by the local early-type galaxy population - a typical massive early-type galaxy can have experienced only ˜1.5 major mergers before becoming a significant outlier in the Mg b-Vesc relation.

Women's Satisfaction with Body Image before Pregnancy and Body Mass Index 4 Years after Delivery in the Mothers of Generation XXI  

PubMed Central

Background Body image satisfaction (BIS) influences body weight regulation and may contribute to long-term healthier lifestyle after pregnancy. Thus, we aimed to assess the association between BIS before pregnancy and body mass index (BMI) 4 years after the index pregnancy. Methods As part of the follow-up of a birth cohort, 3612 women with prepregnancy BMI >18.5 kg/m2 were reevaluated 4 years after the birth of a child. BIS was defined as the difference between perceived and ideal body size before pregnancy, assessed by Stunkard Silhouettes after birth. The associations of BIS with BMI change (continuous) and BMI classes at 4 years, based on measured weight and height, were estimated using linear and multinomial regression, respectively. Results Among women with normal prepregnancy BMI, those who felt too small, regarding their ideal, had a 0.25 kg/m2 smaller increase in BMI within 4 years and a lower likelihood of becoming overweight or obese [multivariate-adjusted odds ratio (OR)?=?0.63; 95% confidence interval (95%CI): 0.44–0.91 and OR?=?0.21; 95%CI: 0.05–0.91, respectively) than those satisfied with body image. Feeling too large was associated with a 0.41 kg/m2 larger increase in BMI and a higher risk of becoming overweight or obese (OR?=?2.12; 95%CI:1.73–2.59 and OR?=?3.42; 95%CI:2.02–5.79, respectively). A similar, non-significant, trend was observed for overweight women. Obese women who felt too large had a non-significant decrease in BMI. Conclusions BIS plays a role in maternal body weight after delivery. Realistic body size goals may promote the motivation to lose weight and contribute to higher success in attaining them.

Extreme Geophysical and Weather Related Disasters in the First Decade of the XXI Century - How do the Patterns of these Two Groups of Perils Differ?  

NASA Astrophysics Data System (ADS)

The first decade of the 21st century saw natural disasters with an unprecedent level of losses, such as the costliest natural disaster ever, the earthquake and tsunami disaster of March 2011 in Japan (US 210bn in direct economic losses), or Hurricane Katrina in 2005 (US 125bn in direct economic losses). In the first half year of 2011, a fierce tornado season occurred in the US with record-breaking thunderstorm-related losses (US$ 24bn in direct economic losses). Analysing drivers of increasing losses, the most prominent one is increasing and more than ever spatially concentrated destroyable wealth in course of urban sprawl, where loss amplifying factors such as increasingly interwoven streams of goods and services across regions or knock-on catastrophes contribute to recently observed very large losses. Looking at longer time series of annually aggregated numbers and losses of geophysical and weather-related disasters, we find regional indications for the hypothesis that besides socioeconomic changes in wealth and development patterns also natural variability and climate change are already involved in the specific time series patterns of the weather-related proportion. This has to be seen against the background of scientific studies demonstrating an interrelation of anthropogenic climate change and weather extremes.

Design and Analysis of Salmonid Tagging Studies in the Columbia Basin, Volume XXI; A Summary of Methods for Conducting Salmonid Fry Mark-Recapture Studies for Estimating Survival in Tributaries, Technical Report 2005-2006.  

SciTech Connect

Productivity and early fry survival can have a major influence on the dynamics of fish stocks. To investigate the early life history of fish, numerous methods have been developed or adapted to these much smaller fish. Some of the marking techniques provide individual identification; many others, only class identification. Some of the tagging techniques require destructive sampling to identify a mark; other methods permit benign examination and rerelease of captured fish. Sixteen alternative release-recapture designs for conducting fry survival investigations were examined. Eleven approaches were found capable of estimating survival parameters; five were not. Of those methods capable of estimating fry survival, five required unique marks, four required batch-specific marks, and two approaches required remarking and rereleasing captured fry. No approach based on a simple batch mark was capable of statistically estimating survival.

Epidemiology of double aneuploidies involving chromosome 21 and the sex chromosomes.  

PubMed

The chance of two chromosome abnormalities occurring in one conceptus is very small. However, some authors have suggested that double aneuplodies (DAs) might be more common than the product of their individual frequencies. The nonrandomness of such DA events was considered to be evidence that nondisjunction (NDJ) may be genetically determined. Data collected from the National Down syndrome Cytogenetic Register (NDSCR) in England and Wales and from the literature indicate that the frequencies of all nonmosaic DAs, except for 48,XXY,+21, are lower than expected, probably because of strong intrauterine selection against such pregnancies. Collectively, we identified 52 cases of nonmosaic 48,XXY,+21; 28 cases of 48,XYY,+21; and 14 cases of 48,XXX,+21 in liveborns and 13 cases of 48,XXY,+21; four cases of 48,XYY,+21; and two cases of 48,XXX,+21 after prenatal diagnoses. Among these cases, analysis of the published unbiased cytogenetic surveys of liveborn DS revealed 24 cases of 48,XXY,+21; nine cases of 48,XYY,+21; and seven cases of 48,XXX,+21. These figures are different from the expected proportion of 1:1:1 (P < 0.001), with carriers of XXY overrepresented in the group of carriers of DA. Mechanisms put forth to account for the higher occurrence of 48,XXY,+21 may include greater accessibility of disomic ovum to Y-carrying sperm, and promotion of NDJ in ovum by Y-bearing sperm. 48,XXY,+21 DA was found to be age-dependent, as the proportion of mothers over age 35 (x = 33.0) was increased over the general population. This is in contrast to the apparently age-independent 48,XYY,+21 DA, with a mean maternal age of 24.7 (P < 0.001). Paternal ages were also remarkably different between the groups, with a mean age of 37.9 in 48,XXY,+21 cases and a mean age of 27.9 in 48,XYY,+21 cases (P < 0.01). Maternal age-related factors, rather than genetic predisposition, may play a more important role in the etiology of the most common DA, 48,XXY,+21. PMID:15704133

Male infertility in Northeast China: molecular detection of Y chromosome microdeletions in azoospermic patients with Klinefelter's syndrome.  

PubMed

The prevalence of microdeletions of azoospermia factor (AZF) among azoospermic Klinefelter's syndrome (KFS) patients shows conflicting data. We aimed to detect this frequency in a Northeast Chinese population, and to investigate the possible association between AZF microdeletions and KFS by comparison with previous conflicting reports. Eighty men affected with KFS and a random healthy control group comprising 60 fertile men and women were recruited. AZF microdeletions were detected by multiplex polymerase chain reaction using 9 specific sequence-tagged sites. Karyotype analyses were performed on peripheral blood lymphocytes using standard G-banding. Finally, azoospermia was confirmed in 77 men affected with KFS and no AZF microdeletions were found. Karyotype analysis revealed 1 patient with karyotype 47,XXY,inv (9) (p11, q13), and 2 with mosaic karyotypes (46,XX/47,XXY and 46,XY/47,XXY). All other patients had karyotype 47,XXY. Review of the literature showed that these results were similar to those of other regions of Northeast Asia, but differed from those obtained from Caucasian populations. Our results supported the proposal that AZF microdeletions and KFS result from separate genetic defects. The prevalence of AZF in azoospermic KFS patients varies among populations, and it might result from genetic drift or selective pressure. These results suggest that routine screening for classical AZF microdeletions among infertile azoospermic men with a 47,XXY karyotype might not be necessary in Northeast Chinese individuals. However, it remains imperative for patients considering assisted reproductive treatments, particularly for those with mosaic karyotypes. PMID:24301758

Space Telescope Imaging Spectrograph Survey of Far-Ultraviolet Coronal Forbidden Lines in Late-Type Stars  

NASA Astrophysics Data System (ADS)

We describe an extensive search with the Space Telescope Imaging Spectrograph (STIS) for ultraviolet coronal (T>106 K) forbidden lines in a sample of 29 F-M dwarfs, giants, and supergiants. Measuring coronal lines in the 1150-1700 Å band with STIS has important advantages of superior velocity resolution and an absolute wavelength calibration compared with using the Chandra or XMM-Newton grating spectrometers to observe permitted transitions of the same ion stages in the kilovolt X-ray region. Fe XII ??1242, 1349 (T~2×106 K) and Fe XXI ?1354 (107 K) are well known from solar studies and have been reported in previous stellar work. A search for other coronal forbidden lines in the 1200-1600 Å region was largely negative. The few candidate identifications (e.g., Ar XIII ?1330 and Ca XV ?1375) are too faint to be diagnostically useful. We add new dwarfs to the list of Fe XII detections, including the nearby solar twin ? Cen A (G2 V). Clear detections of Fe XXI were obtained in dMe stars, active giants, a short-period RS CVn binary, and possibly in active solar-type dwarfs. We developed a semiempirical method for removing the C I blend that partially affects the Fe XXI ?1354 profile. As discussed recently by Johnson et al., Capella (? Aur; G8 III+G1 III) displays clear Fe XXI variability between Goddard High-Resolution Spectograph (GHRS) and STIS observations 4 yr apart, which is apparently due to a substantial decline in the contribution from the G8 primary. We present an alternative model of the GHRS and STIS era profiles using information in the two sets of line shapes jointly, as well as knowledge of the behavior of Fe XXI profiles of other late-G ``clump'' giants similar to Capella G8. The full survey sample also provides a context for the apparent variability: the Fe XXI flux of the G8 star in the GHRS spectrum is nearly identical (in LFeXXI/Lbol) to other clump giants of similar LX/Lbol, but it had dropped at least a factor of 6 in the STIS measurement. The He II ?1640 B? feature-which is thought to be responsive to coronal irradiation-also showed significant changes between the GHRS and STIS epochs, but the decrease in the G8 star was much smaller than Fe XXI. The Fe XII flux displays a correlation with the ROSAT 0.2-2 keV X-ray flux that can be described by an ?=0.5 power law. Fe XXI exhibits a steeper, perhaps linear (?=1), correlation with the ROSAT flux down to an activity level of LX/Lbol~10-5, below which detections of the coronal forbidden line are rare. There is no evidence of large, systematic Doppler shifts in either Fe XII ?1242 or Fe XXI ?1354. This suggests that the emissions arise dominantly in confined structures, analogous to magnetic loops on the Sun, rather than, say, in a hot wind. The Fe XII and Fe XXI line widths generally are close to thermal (FWHM~40-90 km s-1 at T~106.2-107.0 K), except for the Hertzsprung-gap giants 31 Comae (G0 III) and Capella G1 and the K1 subgiant primary of HR 1099, all of which show evidence for excess broadening in Fe XXI (Fe XII is obscured in these objects by broad N V ?1242 features). If the excess broadening is rotational, it implies that the hot coronae of ``X-ray-deficient'' 31 Com and Capella G1 are highly extended, contrary to the compact structures suggested by recent density estimates in a number of active coronal sources.

The data allow detailed comparison with recent theoretical predictions for the Ti XXI helium-like lines and the associated satellite spectrum in the wavelength range from 2.6000 to 2.6400 A. Improved values for the excitation rate coefficients of the Ti XXI resonance line, the intercombination lines and the forbidden line, and new theoretical results on the wavelengths and transition probabilities for beryllium-like satellites due to transitions of the type 1s/sup 2/ 2lnl' - 1s2p2l'' nl'' with n = 2-4 have been calculated.

A Rare Case of Klinefelter Syndrome Patient with Quintuple Mosaic Karyotype, Diagnosed by GTG-Banding and FISH  

PubMed Central

Klinefelter syndrome (KS) is the most common sex chromosomal disorder in men. Most of these patients show the 47,XXY karyotype, whereas approximately 15% of them are mosaics with variable phenotype. A 39-year-old male investigated for primary infertility, was clinically normal with small firm testes and elevated levels of FSH, LH and low level of testosterone. Total azoospermia was confirmed on semen analysis. Testicular histopathology revealed no spermatogenesis and absence of germ cells. Karyotype from whole blood culture showed cells with 47,XXY/46,XX/ 45,X/48,XXXY/ 46,XY mosaicism. The predominant cell line was 47,XXY (83.67%). This was confirmed by fluorescence in situ hybridization (FISH). Also the presence of a small population of cells with the 48,XXXY and 45,X karyotypes was detected by FISH. This case illustrates the utility of FISH as an adjunct to conventional cytogenetics in assess the chromosome copy number in each cell line of a mosaic.

Sobre las edades de las componentes del sistema PSR B1855+09  

NASA Astrophysics Data System (ADS)

In the last few years several low-mass white dwarfs (helium white dwarfs, He WD) have been detected as companions to millisecond pulsars. In this kind of systems, pulsar emission is activated by mass transfer episodes, which also lead to the formation of the He WD, thus if we set the zero age point at the end of this mass loss transfer episodes, the ages of both objects should be the same. In this sense, PSR B1855+09 system casts some doubts about the correctness of theoretical white dwarf models. The age of the pulsar inferred from its spin-down rate is 5 Gyr. However, existing determination of the mass of the white dwarf companion of this system and recent optical detection of it, which has allowed to infer its effective temperature, have led to an estimative age of 10 Gyr for the white dwarf. Noteworthly, available theoretical calculations used to infer the cooling age of the He WDs, neglect element diffusion. In this work, we present evolutionary calculations for He WDs taking into account the effects of gravitational settling, and chemical and thermal diffusion in a self consistent way, and in particular we use the results to determine cooling ages for He WDs. We find that models within the mass range 0.19 <= M/Msolar <= 0.41 suffer from diffusion-induced thermonuclear flashes, during which an appreciable amount of the hydrogen of the envelope is burnt. Only after the hydrogen envelope has been reduced enough so as not to be able to produce another thermonuclear flash, He WD models evolve towards their final cooling track. During this evolutionary stage, cooling rate is determined by whether stable hydrogen burning is relevant or not. We find that diffusion-induced thermonuclear flashes reduce the hydrogen envelope so as to prevent stable hydrogen burning from being an appreciable source of energy for the models, which are then forced to a rapid cooling. In this way, expected ages for these objects are drastically reduced when compared to the case in which diffusion is neglected (as these models predict thick hydrogen envelopes and thus, a cooling stage dominated by stable hydrogen burning). In particular, we find for the white dwarf companion to PSR B1855+09 an age of 4±2 Gyr, which is in very good agreement with the spin-down age of this pulsar and also shows that the age discrepancy previously found is due to an oversimplification in the physical ingredients of theoretical models.

Efecto de las colisiones sobre el Plano Fundamental de bulbos de galaxia espirales  

NASA Astrophysics Data System (ADS)

The main aspects of the Fundamental Plane (FP) relation for ellipticals and early type bulges can be explained assuming the virialization of the systems, however, the observed dispersions are larger than instrumentation errors and have been thought to have physical basis. Even more, it is expected that the scatter and the position that different objects ocupy on it, could give clues on the mechanisms of galaxy formation and on the evolutionary path of galaxies. The FP relation has been observed and confirmed in the local Universe and it has been recently estimated for galaxies at intermediate redshifts. However, these estimations are based on a low statitical number and effects such as the evolution of the stellar populations and the presence of dust may introduce additional dispersion. Scannapieco & Tissera (2003) studied the mass distribution of disk systems and the way in which this distribution is modified by mergers. These authors have used numerical simulations which included gravitation, hydrodynamics, cooling and stellar formation in a cosmological frame work. As a consecuence, the collision parameters and the physical features of the simulated objects are the result of the consistent formation of the structure in a hierarchical scenario. The results show that depending on the caracteristics of the potential well, some systems may suffer gas inflows as a result of tidal fields during the orbital decay of the satellite system. This gas inflow originates a star burst previous to the fusion (i.e. secular evolution) which tends to form bulges with exponential profiles. In this work we present preliminary results on the effects of mergers on the FP defined by bulges. We found that the simulated bulges determines a FP in agreement with observations. We have detected that the mergers could significantly affect the FP depending on the internal properties of the galactic systems. And, particularly, secular evolution is found to play a critical role in the determination of a FP with the observed slope (Smith Castelli et al., 2004, in preparation).

Profesionalismo: Un estudio fenomenologico sobre experiencias de universitarios en programas de salud  

NASA Astrophysics Data System (ADS)

Some studies suggest that, upon admission, medicine programs students display eagerness for community service, aspirations to be useful, and to contribute to society's well-being. Those same studies reflect that qualities of idealism, moral nature, and internal motivation, suffer a subsequent diminishing. The researchers inferred that the main reason for this process of change in the mood and disposition of these future physicians lies in the modeling they receive from medical professionals throughout clinical learning activities, by way of behavior and relationships exhibited during daily interaction with peers, patients and the students themselves. This phenomenological study used a cross-sectional sample to explore the experiences of future health workers as they went through didactic and clinical phases of their training curriculum. The study employed semi-structured interviews and reflective journals to explore those experiences and to discover the meanings ascribed by the participants. The analysis revealed that the students defined "professionalism" in terms of scientific knowledge, commitment, respect for human dignity, comradeship, courtesy, empathy, integrity, altruism, motivation. They also described their feelings as they went through the didactic and clinical experiences, and recognized as very important the extracurricular activities of community service, describing them as useful opportunities which contributed to understand their work in terms of a mission dedicated to the achievement of the social benefit. From their individual perspectives, the clinical environment could, in general, be described as congruent with those characteristics of professionalism. During the study we had the opportunity to share, in a little deeper way, the environment... the world... of this small group of young students as we went on trying to decipher their feelings and thoughts. At the end, we realized the richness of their sensibilities, we perceived the intensity of their moral and ethical convictions, we were able to understand their concerns, worries, struggles and efforts. This life event had profound and significant repercussions in our personal and professional life. As a result, and from now on, we will no longer look at our young scholars and apprentices without imagining a noble spirit, with goals which at times could seem unattainable... without completely visualizing or conceiving real hope for a better country.

Effects of sex chromosome aneuploidy on male sexual behavior.  

PubMed

Incidence of sex chromosome aneuploidy in men is as high as 1:500. The predominant conditions are an additional Y chromosome (47,XYY) or an additional X chromosome (47,XXY). Behavioral studies using animal models of these conditions are rare. To assess the role of sex chromosome aneuploidy on sexual behavior, we used mice with a spontaneous mutation on the Y chromosome in which the testis-determining gene Sry is deleted (referred to as Y(-)) and insertion of a Sry transgene on an autosome. Dams were aneuploid (XXY(-)) and the sires had an inserted Sry transgene (XYSry). Litters contained six male genotypes, XY, XYY(-), XXSry, XXY(-)Sry, XYSry and XYY(-)Sry. In order to eliminate possible differences in levels of testosterone, all of the subjects were castrated and received testosterone implants prior to tests for male sex behavior. Mice with an additional copy of the Y(-) chromosome (XYY(-)) had shorter latencies to intromit and achieve ejaculations than XY males. In a comparison of the four genotypes bearing the Sry transgene, males with two copies of the X chromosome (XXSry and XXY(-)Sry) had longer latencies to mount and thrust than males with only one copy of the X chromosome (XYSry and XYY(-)Sry) and decreased frequencies of mounts and intromissions as compared with XYSry males. The results implicate novel roles for sex chromosome genes in sexual behaviors. PMID:18363850

Prevalence and Psychosocial Correlates of Depressive Symptoms among Adolescents and Adults with Klinefelter Syndrome  

PubMed Central

Purpose To determine the prevalence and psychosocial correlates of depressive symptoms among adolescents and adults with Klinefelter syndrome (XXY). Methods Individuals (n=310) aged 14–75 years with self-reported XXY were recruited from regional and national support networks to complete a web-based survey. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Perceived consequences (Illness Perceptions Questionnaire), perceived stigma (Perceived Social Stigmatization Scale), and coping (Ways of Coping Checklist-Revised) were also measured and evaluated as correlates of depressive symptoms. Results 68.8% of the study participants reported clinically significant levels of depressive symptoms as indicated by a CES-D score ?16. The use of emotion-focused coping strategies (p<0.01), perceptions of stigmatization (p<0.01), perceived negative consequences of XXY (p<0.01), and the importance of having children in the future (p<0.05) were all significantly associated with depressive symptoms. Conclusions Individuals with XXY may be at increased risk for depression. Routine screening for depressive symptoms and appropriate referral and evaluation may be warranted.

Description of children with 45,X/46,XY karyotype.  

PubMed

We hypothesized that because 45,X/46,XY (X/XY) children share a cell line with Turner syndrome (TS), they also share co-morbidities described in TS. In addition, the presence of the Y chromosome in brain and in other body tissues would influence their function. On the basis of our findings, we aimed to establish optimal procedures for clinical evaluation, management, and follow-up of these children. Sixteen X/XY children were evaluated and managed at a single institution as part of standard clinical care as established at the time between 1969 and 2009. In January of 2005, we started retrospective record review of all X/XY children in combination with cohort follow-up (of those who had not reached adult height) until August of 2009. The study included review of clinical presentation, clinical characteristics, diagnostic measures, radiologic studies, karyotype studies, psycho-endocrinology evaluation, and growth-promoting treatments. There was no specific intervention. Phenotype reflected cell line distribution. The presence of 45,X cell line explains how X/XY children have abnormalities similar to girls with TS, while presence of Y chromosome explains why they have tomboyish behavior. In conclusion, these children require clinical evaluation similar to that performed in female children with TS, including cardiovascular, renal, endocrine, growth and development, autoimmune, psychological, and educational evaluation. Specific management needs to be tailored to the presence of Y chromosomal material. PMID:21997800

Teorí­as de primer y segundo orden sobre el potencial de ciertas figuras de equilibrio de cuerpos celestes  

NASA Astrophysics Data System (ADS)

Uno de los problemas que aborda la Mecánica Celeste es la determinación de las figuras de equilibrio de los cuerpos celestes. Para investigar su solución mediante métodos directos, se precisa evaluar el potencial generado por su autogravitación, el generado por su fuerza centrí­fuga y el generado por la fuerza de atracción entre los cuerpos. Los métodos clásicos de Finlay y Kopal que afrontan estos problemas, para determinar el potencial autogravitatorio en las configuraciones de equilibrio, emplean desarrollos en serie de los potenciales interior y exterior del potencial autogravitatorio. Estos métodos incurren en el error de suponer la convergencia en capas donde resulta cuestionable dicha convergencia para estos desarrollos en serie. En este trabajo se han elaborado unos algoritmos que contemplan toda la casuí&stica y que permiten una manipulación efic iente del producto de polinomios de Legendre, del producto de funciones asociada s de Legendre y del producto de armónicos esféricos como combinacióon lineal de ellos mismos, respectivamente. Se han obtenido, para primer y segundo orden en las amplitudes, los desarrollos correctos para los potencial es interior y exterior del potencial autogravitatorio para configuraciones de equilibrio aisladas, y , en primer orden de amplitudes, los mismos potenciales para los sistemas binarios próximos. Se ha elaborado un método analítico, en primer orden respecto de las amplitudes, para la determinación del potencial de marea en sistemas binarios próximos en el cual se manifiesta la forma de la componente secundaria del sistema

Analysis of ultraviolet and X-ray observations of three homologous solar flares from SMM  

NASA Technical Reports Server (NTRS)

Three homologous flares observed in the UV lines of Fe XXI and O V and in X-rays from the SMM were studied. It was found that: (1) the homology of the flares was most noticeable in Fe XXI and soft X-ray emissions; (2) the three flares shared many of the same loop footprints which were located in O V bright kernals associated with hard X-ray bursts; and (3) in spite of the strong spatial homology, the temporal evolution in UV and X-ray emissions varied from flare to flare. A comparison between the UV observations and photospheric magnetograms revealed that the basic flare configuration was a complex loop system consisting of many loops or bundles of loops.

New model for nucleon generalized parton distributions  

SciTech Connect

We describe a new type of models for nucleon generalized parton distributions (GPDs) H and E. They are heavily based on the fact nucleon GPDs require to use two forms of double distribution (DD) representations. The outcome of the new treatment is that the usual DD+D-term construction should be amended by an extra term, {xi} E{sub +}{sup 1} (x,{xi}) which has the DD structure {alpha}/{beta} e({beta},{alpha}, with e({beta},{alpha}) being the DD that generates GPD E(x,{xi}). We found that this function, unlike the D-term, has support in the whole -1 <= x <= 1 region. Furthermore, it does not vanish at the border points |x|={xi}.

Testicular function and fertility in men with Klinefelter syndrome: a review.  

PubMed

Klinefelter syndrome, 47,XXY (KS), is the most frequent sex chromosome aberration in males, affecting 1 in 660 newborn boys. The syndrome is characterized by testicular destruction with extensive fibrosis and hyalinization of the seminiferous tubules resulting in small testes, hypergonadotropic hypogonadism, and azoospermia in the majority of cases. Until recently, infertility was considered an untreatable condition in KS. However, with the development of new advanced assisted reproductive techniques such as testicular sperm extraction (TESE) combined with ICSI it seems that KS patients should no longer be labelled as infertile. Especially, microdissection (micro)-TESE has proved to be an advantageous procedure for the identification of testicular spermatozoa in KS. The aim of this review was to describe current knowledge on the testicular changes occurring in KS, the associated changes in reproductive hormones and spermatogenesis, and the existing possibilities of biological fatherhood in 47,XXY patients.

48,XXYY, 48,XXXY and 49,XXXXY syndromes: not just variants of Klinefelter syndrome  

PubMed Central

Sex chromosome tetrasomy and pentasomy conditions occur in 1:18 000–1:100 000 male births. While often compared with 47,XXY/Klinefelter syndrome because of shared features including tall stature and hypergonadotropic hypogonadism, 48,XXYY, 48,XXXY and 49,XXXXY syndromes are associated with additional physical findings, congenital malformations, medical problems and psychological features. While the spectrum of cognitive abilities extends much higher than originally described, developmental delays, cognitive impairments and behavioural disorders are common and require strong treatment plans. Future research should focus on genotype–phenotype relationships and the development of evidence-based treatments. Conclusion The more complex physical, medical and psychological phenotypes of 48,XXYY, 48,XXXY and 49,XXXXY syndromes make distinction from 47,XXY important; however, all of these conditions share features of hypergonadotropic hypogonadism and the need for increased awareness, biomedical research and the development of evidence-based treatments.

The expansion velocities of laser-produced plasmas determined from extreme ultraviolet spectral line profiles  

NASA Technical Reports Server (NTRS)

The expansion of laser-produced plasma is determined from the shapes of spectral lines of highly ionized iron emitted in the extreme ultraviolet. The plasmas were produced by focusing the pulse from a Nd:glass laser onto solid planar targets, and spectra were recorded with a high-resolution grazing-incidence spectrograph. From the Doppler broadening of lines of Fe XX and Fe XXI, expansion velocities of about 830 km/s were determined. The relative time-averaged ion abundances of Fe XVIII, Fe XIX, Fe XX, and Fe XXI are estimated for three different spectra. The abundances do not differ by more than a factor of 4 for any of the spectra.

46,X,del(X)(q13) Turner's Syndrome Female with Systemic Lupus Erythematosus in a Pedigree Multiplex for SLE  

PubMed Central

Systemic lupus erythematosus (SLE) disproportionately affects females. Recent work demonstrates that men with Klinefelter's syndrome (47,XXY males) have a similar risk of developing SLE as do genotypic females. We present an unusual case of an African American family with two SLE affected individuals in which one of the SLE patients also has Turner's syndrome [46,X,del(X)(q13)]. While not definitive, this family raises interesting questions regarding the role of genes located on the X chromosome in the development of SLE. The paucity of case reports documenting the overlap of SLE with Turner's syndrome while there is and association of male SLE with Klinefelter's syndrome suggests a lower risk of SLE in Turner's females. These observations are consistent with a gene dose effect at X with two X chromosomes (46,XX or 47,XXY) conferring higher risk and one X chromosome (46,XY or 45,XO) conferring lower risk of SLE.

PI phenotypes (including subtypes) were determined for 168 individuals with chromosomal abnormalities ascertained in Adelaide. These included patients with mosaicism, trisomy 21, trisomy 13, trisomy 18, and various sex chromosome aberrations (45,X, 47,XXX, 47,XXY, 47, XYY, and 48,XXXY). Data did not support an existing proposition that mildly deficient PI phenotypes predispose to abnormal chromosome segregation during mitosis of meiosis. Phenotypic distributions of each group were statistically similar to control populations of cord bloods and bloods donors. PMID:6971795

[Is it useful to modify the care of Klinefelter's syndrome to improve the chances of paternity?].  

PubMed

Until a few years ago, Klinefelter syndrome with a homogeneous 47.XXY karyotype was considered a model of absolute male sterility. In this review, we will discuss: (1) potential fertility following TEsticular Sperm Extraction-IntraCytoplasmic Sperm Injection (TESE-ICSI), (2) the physiopathology of spermatogenic failure and the origin of focal spermatogenesis and risk of aneuploidy in potential offspring, (3) the advantage of searching for and cryopreserving spermatozoa in adolescent instead of adult patients. In previous published series, TESE was successful in almost 50% of patients and pregnancy rate following ICSI was not obviously different from other causes of spermatogenic failure. The rate of positive sperm extraction seemed to be better for younger patients. During childhood, the survival rate of 47.XXY spermatogonia is low. However, a few spermatogonia are able to eliminate their extra X chromosome, giving rise to rare clones of 46.XY gonia which are the origin of rare foci of complete spermatogenesis after puberty. Several arguments suggest that this focal spermatogenesis decreases with age. This suggests there would be a benefit to patients if TESE were performed in adolescences and spermatozoa were cryopreserved. In addition, androgenotherapy is a common treatment of Klinfelter syndrome but carries a risk of decreasing focal spermatogenesis by lowering gonadotropins. Preservation of spermatozoa from adolescence by TESE would allow androgenotherapy to be prescribed with less concern for future reproductive capacity. Controlled studies should be done to determine the best age for TESE-ICSI in 47.XXY homogeneous Klinefelter syndrome patients. PMID:20727517

SNP-based non-invasive prenatal testing detects sex chromosome aneuploidies with high accuracy  

PubMed Central

Objective To develop a single nucleotide polymorphism- and informatics-based non-invasive prenatal test that detects sex chromosome aneuploidies early in pregnancy. Methods Fifteen aneuploid samples, including thirteen 45,X, two 47,XXY, and one 47,XYY, along with 185 euploid controls, were analyzed. Cell-free DNA was isolated from maternal plasma, amplified in a single multiplex PCR assay that targeted 19,488 polymorphic loci covering chromosomes 13, 18, 21, X, and Y, and sequenced. Sequencing results were analyzed using a Bayesian-based maximum likelihood statistical method to determine copy number of interrogated chromosomes, calculating sample-specific accuracies. Results Of the samples that passed a stringent quality control metric (93%), the algorithm correctly identified copy number at all five chromosomes in all 187 samples, for 934/935 correct calls as early as 9.4 weeks of gestation. We detected 45,X with 91.7% sensitivity (CI: 61.5-99.8%) and 100% specificity (CI: 97.9-100%), and 47,XXY and 47,XYY. The average calculated accuracy was 99.78%. Conclusion This method non-invasively detected 45,X, 47,XXY, and 47,XYY fetuses from cfDNA isolated from maternal plasma with high calculated accuracies, and thus offers a non-invasive method with the potential to function as a routine screen allowing for early prenatal detection of rarely diagnosed yet commonly occurring sex aneuploidies.

Integrated sight: future improvement for Land Warrior  

NASA Astrophysics Data System (ADS)

The Integrated Sight (IS) is a Technology Demonstration program within the Force XXI Land Warrior Program. Like the other Force XXI Land Warrior components, the IS is a candidate for future technology insertion into the Land Warrior (LW) program. The IS integrates an uncooled thermal imager, eye- safe laser rangefinder, electronic compass, CCD camera and infrared laser pointer into a single lightweight sight. It can mount on weapons or be used in a handheld or tripod mode. The functionality of the IS provides the fighting soldier with the ability to acquire targets during daylight, darkness, adverse weather, and through battlefield obscurants to provide target position data (azimuth and range) for indirect fire. Standardized interfaces enable digital target location data and imagery to be transmitted to and from the LW computer/radio subsystem (CRS). By integrating the sensors into a single unit, the IS offers reductions in weight, power, and size which is expected to improve the LW soldier's fightability. The impact of sensor integration on the LW soldier's tasks will be evaluated during Force XXI Land Warrior testing. The IS is being developed jointly by Raytheon Texas Instruments Systems (RTIS), the U.S. Army CECOM RDEC Night Vision and Electronic Sensors Directorate, and the U.S. Army Soldier Systems command. This paper provides a comparative assessment of the IS and the LW baseline Weapon Subsystem, and outlines the expected improvements that the IS provides the fighting soldier.

Energy release topology in a multiple-loop solar flare  

NASA Technical Reports Server (NTRS)

The temporal and spatial structures of the UV and X-ray emissions and the magnetic field configuration in the November 12, 1980 flare observed from SMM have been studied. The UV observations were done in the O V and Fe XXI lines with a spatial resolution of 10 arcsec. The observations show that the impulsive UV bursts, and also the hard X-ray bursts by their temporal correlation with the impulsive O V emission, occurred in small localized kernels. By comparing the O V, Fe XXI, and X-ray raster images of the flare with the magnetogram, these emission kernels were identified as footpoints of interacting magnetic flux loops. The temporal evolution of the O V/Fe XXI emission shows that there was considerable preheating in the flare plasma some 8-9 minutes prior to the onset of the main hard X-ray bursts. The results are interpreted as indicating that the primary flare energy release occurred in a highly sheared multiloop structure, which lies along a magnetic neutral line. By either beam particle propagation or convective motion, flare energy is transported via a common footpoint to another loop which brightened later. The preheating of the flare plasma is shown to create a more favorable environment for energetic particle acceleration which resulted in the main impulsive hard X-ray bursts.

A tortoiseshell male cat: chromosome analysis and histologic examination of the testis.  

PubMed

Tortoiseshell coat color is normally restricted to female cats due to X-linkage of the gene that encodes the orange coat color. Tortoiseshell male cats do, however, occur at a low frequency among tortoiseshell cats because of chromosome aberrations similar to the Klinefelter syndrome in man: the extra X chromosome of a 39,XXY karyotype introduces the possibility of an orange and a non-orange allele which produce the mixture of orange and non-orange coat spotting known as tortoiseshell. We analyzed the chromosome complement of a fibroblast culture and did histological examinations of testicular tissue from a tortoiseshell male cat referred to us. Chromosome analysis using RBA-banding consistently revealed a 39,XXY karyotype. Histological examinations of testis biopsies from this cat showed degeneration of the tubules, hyperplasia of the interstitial tissue, and complete loss of germ cells. Immunostaining using anti-vimentin and anti-VASA (DDX4) showed that only Sertoli cells and no germ cells were observed in the testicular tubules. As no sign of spermatogenesis was detected, we conclude that this is a classic case of a sterile, male tortoiseshell cat with a 39,XXY chromosome complement. PMID:24335095

Battlefield awareness computers: the engine of battlefield digitization  

NASA Astrophysics Data System (ADS)

To modernize the army for the 21st century, the U.S. Army Digitization Office (ADO) initiated in 1995 the Force XXI Battle Command Brigade-and-Below (FBCB2) Applique program which became a centerpiece in the U.S. Army's master plan to win future information wars. The Applique team led by TRW fielded a 'tactical Internet' for Brigade and below command to demonstrate the advantages of 'shared situation awareness' and battlefield digitization in advanced war-fighting experiments (AWE) to be conducted in March 1997 at the Army's National Training Center in California. Computing Devices is designated the primary hardware developer for the militarized version of the battlefield awareness computers. The first generation of militarized battlefield awareness computer, designated as the V3 computer, was an integration of off-the-shelf components developed to meet the agressive delivery requirements of the Task Force XXI AWE. The design efficiency and cost effectiveness of the computer hardware were secondary in importance to delivery deadlines imposed by the March 1997 AWE. However, declining defense budgets will impose cost constraints on the Force XXI production hardware that can only be met by rigorous value engineering to further improve design optimization for battlefield awareness without compromising the level of reliability the military has come to expect in modern military hardened vetronics. To answer the Army's needs for a more cost effective computing solution, Computing Devices developed a second generation 'combat ready' battlefield awareness computer, designated the V3+, which is designed specifically to meet the upcoming demands of Force XXI (FBCB2) and beyond. The primary design objective is to achieve a technologically superior design, value engineered to strike an optimal balance between reliability, life cycle cost, and procurement cost. Recognizing that the diverse digitization demands of Force XXI cannot be adequately met by any one computer hardware solution, Computing Devices is planning to develop a notebook sized military computer designed for space limited vehicle-mounted applications, as well as a high-performance portable workstation equipped with a 19', full color, ultra-high resolution and high brightness active matrix liquid crystal display (AMLCD) targeting the command posts and tactical operations centers (TOC) applications. Together with the wearable computers Computing Devices developed at the Minneapolis facility for dismounted soldiers, Computing Devices will have a complete suite of interoperable battlefield awareness computers spanning the entire spectrum of battle digitization operating environments. Although this paper's primary focus is on a second generation 'combat ready' battlefield awareness computer or the V3+, this paper also briefly discusses the extension of the V3+ architecture to address the needs of the embedded and command post applications.

Vínculos sobre um modelo de quartessência de Chaplygin usando observações do satélite chandra da fração de massa de gás em aglomerados de galáxias  

NASA Astrophysics Data System (ADS)

Observações de Supernovas do tipo Ia mostram que a expansão do Universo está acelerando. Segundo as equações de Einstein uma componente com pressão negativa (energia escura) é necessária para explicar a aceleração cósmica. Além da energia escura é usualmente admitido que no Universo há também uma matéria exótica com pressão zero, que é chamada de matéria escura. Essa componente possui um papel fundamental na formação de estruturas no Universo. Recentemente tem se explorado a possibilidade de que matéria e energia escura poderiam ser unificadas através de uma única componente, que tem sido denominada de quartessência. Um exemplo de fluido com essas características é o Gás de Chaplygin Generalizado, que possui uma equação de estado da forma p = -A/ra. Inicialmente consideramos o caso especial a = 1 (gás de Chaplygin) e vinculamos parâmetros do modelo utilizando observações em raios-X do satélite Chandra da fração de massa de gás em aglomerados de galáxias. Uma comparação dos vínculos obtidos com esse teste com outros testes, tais como supernovas e idade do Universo, mostra que esse teste é bastante restritivo.

[Actividad inhibitoria de dihidroxifenil propenona sobre betalactamasas de Enterobacter cloacae: estudio preliminar en el desarrollo de fármacos para enfrentar la resistencia bacteriana].  

PubMed

Introduction: Enterobacter cloacae is a pathogenic microorganism with the ability to produce betalactamase enzymes, which makes them resistant to betalactamic antibiotics. Additionally, the limited activity of enzymatic inhibitors has been identified, and, therefore, the design of new drugs and the promotion of their rational use are the only possibilities to overcome this problem. Objective: The aim of this research was to evaluate the effect of dihydroxy-phenyl-propenone on a clinical isolate of E. cloacae , as well as its activity on a betalactamase isolated from this resistant microorganism in order to contribute to the search for new betalactamase inhibitors. Materials and methods: Dihydroxy-phenyl-propenone chalcone was synthesized and evaluated on a clinical isolate of E. cloacae to determine the minimum inhibitory concentration by broth microdilution; once the betalactamase enzyme was purified by affinity chromatography, a spectrophotometric analysis was done to evaluate its kinetic activity. Results: The minimum inhibitory concentration value of dihydroxy-phenyl-propenone on E. cloacae was 35 µg/ml; the recovery percentage of the betalactamase from the microorganism was 31.75% and the kinetic parameters were V max =1.7 x 10 -3 µM/min and K M = 2330 µM, which show an important inhibitory activity. Conclusion: Dihydroxy-phenyl-propenone has shown inhibitory activity on betalactamase enzymes and the ability to protect the chemical integrity of betalactamic antibiotics; this synergistic effect turns it into a promising compound in the search for new alternatives to overcome bacterial resistance.

Sistema de cúmulos globulares de la galaxia lenticular NGC 6861: en busca de indicios sobre la formación de las S0s.  

NASA Astrophysics Data System (ADS)

We present a preliminar photometric study of the globular cluster system (GCS), associated to the lenticular galaxy (S0) NGC 6861, which is located in a low density environment (d˜31.8 Mpc). It is based on GEMINI/GMOS images (GS-2010B-Q-2: PI Lilia P. Bassino) in the filters g', r', i' of three fields, one of them centered in the galaxy. We find a large number of GCs candidates and detect the presence of at least two sub-populations of GCs (``blue''/metal-poor and ``red''/metal-rich). The spatial distribution of ``red'' candidates presents a higher concentration toward the galaxy (associated to the bulge?), while the distribution of ``blue'' candidates is more homogeneus over the three fields (associated to the halo?). In the color-magnitud diagram, the ``blue'' GC candidates show a possible mass-luminosity relation, known as ``blue-tilt'', probably detected for the first time in a lenticular galaxy.
