First wild XXY house mice.  

PubMed

Laboratory house mice (Mus musculus) with the XXY condition can be generated with ease and have been used as a biomedical model. However, although the XXY constitution has been described in humans and many domestic and wild mammal species, and a very large number of wild house mice have been karyotyped previously, no wild individuals of M. musculus with an XXY karyotype have ever been reported. Therefore, it is rather extraordinary that two wild XXY house mice were caught by us on two different farms in northern Italy in 2008. Except for the extra X chromosome, one male had a standard karyotype (2n = 40) and the other, the karyotype of the Cremona metacentric population (2n = 22). In this paper, the phenotype of these two individuals is described. Observations for both of these wild males agree with those of laboratory XXY mice, i.e., they had a normal body mass and appearance, but significantly smaller testes than normal, and no visible germ cells. The incidence of the XXY chromosome anomaly in wild mice (two among 5,123 wild mice surveyed by us and our colleagues, i.e., approximately 0.08% among wild-caught males) is intermediate between that found in male laboratory mice (approximately 0.04%) and that found in male humans (0.2%).

Battlespace situation awareness for Force XXI  

NASA Astrophysics Data System (ADS)

Timely battlefield digitization and battlespace visualization is a requirement to keep pace with ever-diminishing military decision cycle times driven by evolving weapons systems and pacing military doctrine for Force XXI. One ingredient to battlefield situation awareness is imagery intelligence. This paper proposes a novel architecture for an imagery analysis environment to seamlessly provide imagery intelligence. A critical component of this proposed architecture is emerging intelligent software agent technology levering human-computer interface (HCI) technology. This combination enables a modular, scaleable, and reconfigurable battlefield situation awareness and exploitation environment. The consequent impact of this paper is the definition of an entirely new method to support military intelligence, planning and execution processes. The proposed architecture effectively provides real-time/near real-time sensor fusion, sensor management, and battle management in a single collaborative environment. This paper provides the design and describes the technologies necessary to make this system a reality. The proposed design employs the following emerging technologies: (1) open agent architecture -- information gathering/data mining, processing, and dynamic aggregation of agents; (2) multimodal data entry with command and query interfaces -- interact/communicate through voice, writing or gestures; (3) speech recognition and natural language understanding -- speech recognition and speech-to-text translation; (4) procedural and evidential reasoning -- dynamic process control, planning, spatial reasoning, and correlation and behavior; and (5) collaboration -- shared work space applications, wireless and hardwired networks, multiple and distributed participants. In the image analyst-centric environment, this state-of-the-art system will manage automatic and assisted target recognition, and imagery exploitation components, while providing a system capable of ingesting and fusing available tactical, national, and commercial imagery sources. It will also enable fusing multi- intelligence source data. With the addition of collaboration and shared multimedia display the system is capable of redefining the interactive imagery exploitation paradigm. Further, in a military doctrinal sense, our proposed concept provides the potential to blur the dividing line between operational command and control (C2) and its supporting intelligence activities.

Expansion of the phenotypic profile of the young child with XXY.  

PubMed

XXY is a common chromosomal abnormality which remains under diagnosed and not well understood, although it was first described more than 50 years ago. In the last ten years, with advancement in neuroimaging technology and the greater understanding of behavioral neurogenetics, there has been a resurgence of interest in children and adults with XXY. This homogenous population provides insight into the interaction between learning dysfunction, brain development and behavioral performance that may be investigated from birth onward. The unique attributes of the child from birth to 6 years of age with XXY is discussed in this paper. This paper postulates a novel reconceptualization of the phenotypic presentation of the boys with XXY. The neurodevelopmental profile of XXY is actually quite consistent over time with the common thread of speech and language deficits, motor dysfunction and frontal lobe deficits including attention, planning and organization. The early motor and speech disturbances are not random developmental delays, but rather the early presentation of the central nervous system dysfunction associated with XXY. Muscle tonus abnormalities are present in trunk, upper extremities and oral facial musculature in more than 80% of the infants with XXY.Androgen deficiency may be an integral part of the delays observed in boys with XXY, since androgen is influential in brain organization, neurobehavioral development, temperament and mood in humans. It is plausible that the earliest biomarker for androgen deficiency in XXY may be the decreased muscle tonus. Androgen deficiency may not be the only causative factor in the neurodevelopmental disturbance in individuals with XXY, but may promote a restorative function if timing and dosage is appropriate. The study of children with XXY offers an opportunity to observe the impact of the genetic and chromosomal influence on learning and behavior in a population with great homogeneity. XXY is a multifaceted spectrum disorder which demonstrates the complexity of the relationship between brain, behavior, genes and the environment. PMID:21217608

Genetic, hormonal, and metabolomic influences on social behavior and sex preference of XXY mice  

PubMed Central

XXY men (Klinefelter syndrome) are testosterone deficient, socially isolated, exhibit impaired gender identity, and may experience more homosexual behaviors. Here, we characterize social behaviors in a validated XXY mouse model to understand mechanisms. Sociability and gender preference were assessed by three-chambered choice tasks before and after castration and after testosterone replacement. Metabolomic activities of brain and blood were quantified through fractional synthesis rates of palmitate and ribose (GC-MS). XXY mice exhibit greater sociability than XY littermates, particularly for male mice. The differences in sociability disappear after matching androgen exposure. Intact XXY, compared with XY, mice prefer male mice odors when the alternatives are ovariectomized female mice odors, but they prefer estrous over male mice odors, suggesting that preference for male mice may be due to social, not sexual, cues. Castration followed by testosterone treatment essentially remove these preferences. Fractional synthesis rates of palmitate are higher in the hypothalamus, amygdala, and hippocampus of XXY compared with XY mice but not with ribose in these brain regions or palmitate in blood. Androgen ablation in XY mice increases fractional synthesis rates of fatty acids in the brain to levels indistinguishable from those in XXY mice. We conclude that intact XXY mice exhibit increased sociability, differences in gender preference for mice and their odors are due to social rather than sexual cues and, these differences are mostly related to androgen deficiency rather than genetics. Specific metabolic changes in brain lipids, which are also regulated by androgens, are observed in brain regions that are involved in these behaviors.

The spectrum of the behavioral phenotype in boys and adolescents 47,XXY (Klinefelter syndrome).  

PubMed

The behavioral phenotype of 47,XXY (Klinefelter syndrome) includes increased risks for developmental delays, language-based learning disabilities, executive dysfunction/ADHD, and socialemotional difficulties. However there is significant variability between individuals with 47,XXY, and many children and adolescents have minimal or no behavioral features while others have quite significant involvement. This paper describes behavioral features in a cohort of 57 children and adolescents with 47,XXY, including results on standardized measures of behavior (BASC-2), attention (Conner's Rating Scales), and social skills (Social Responsiveness Scale). A subset was directly assessed for autism spectrum disorders using the ADOS and ADIR. We discuss our results within the context of previous literature, including implications for genetic counseling, recommendations for care, and areas for future research. PMID:21217607

Timing of diagnosis of 47,XXY and 48,XXYY: a survey of parent experiences.  

PubMed

47,XXY/Klinefelter syndrome is the most common sex chromosomal aneuploidy, yet 64% of males with this condition go undiagnosed. 48,XXYY is less common and there is less known about the diagnosis. The objective of this study is to describe the diagnosis experiences of parents of males with 47,XXY and 48,XXYY. Parents of 89 males with 47,XXY and 76 males with 48,XXYY completed a survey that gathered data about their experiences leading to a diagnosis, including the current age of the child, age at diagnosis, reasons for initial concern, and the specialists providing the diagnosis. In the 47,XXY cohort diagnosed postnatally, 59% presented with developmental delay, with a mean age at first parental concern of 5.2 years and mean age of diagnosis at 10.0 years. The remaining 41% presented with endocrinologic issues with a mean age at first concern of 19.1 years and mean age of diagnosis at 21.1 years. In the 48,XXYY group, 93% presented with developmental delay, with mean age at first parental concern of 2.4 years and mean age of diagnosis at 7.6 years. Hence, the average time from initial parental concern to diagnosis of 47,XXY or 48,XXYY ranges from 2 to 5 years, with those presenting with developmental issues having a longer lag to diagnosis compared to those presenting with endocrinologic issues. Increased awareness of the developmental, psychological, and medical features of 47,XXY and 48,XXYY is important to facilitate timely diagnosis and initiation of appropriate screenings and treatments that are important for optimal outcomes.

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

The Sex Chromosome Trisomy mouse model of XXY and XYY: metabolism and motor performance  

PubMed Central

Background Klinefelter syndrome (KS), caused by XXY karyotype, is characterized by low testosterone, infertility, cognitive deficits, and increased prevalence of health problems including obesity and diabetes. It has been difficult to separate direct genetic effects from hormonal effects in human studies or in mouse models of KS because low testosterone levels are confounded with sex chromosome complement. Methods In this study, we present the Sex Chromosome Trisomy (SCT) mouse model that produces XXY, XYY, XY, and XX mice in the same litters, each genotype with either testes or ovaries. The independence of sex chromosome complement and gonadal type allows for improved recognition of sex chromosome effects that are not dependent on levels of gonadal hormones. All mice were gonadectomized and treated with testosterone for 3 weeks. Body weight, body composition, and motor function were measured. Results Before hormonal manipulation, XXY mice of both sexes had significantly greater body weight and relative fat mass compared to XY mice. After gonadectomy and testosterone replacement, XXY mice (both sexes) still had significantly greater body weight and relative fat mass, but less relative lean mass compared to XY mice. Liver, gonadal fat pad, and inguinal fat pad weights were also higher in XXY mice, independent of gonadal sex. In several of these measures, XX mice also differed from XY mice, and gonadal males and females differed significantly on almost every metabolic measure. The sex chromosome effects (except for testis size) were also seen in gonadally female mice before and after ovariectomy and testosterone treatment, indicating that they do not reflect group differences in levels of testicular secretions. XYY mice were similar to XY mice on body weight and metabolic variables but performed worse on motor tasks compared to other groups. Conclusions We find that the new SCT mouse model for XXY and XYY recapitulates features found in humans with these aneuploidies. We illustrate that this model has significant promise for unveiling the role of genetic effects compared to hormonal effects in these syndromes, because many phenotypes are different in XXY vs. XY gonadal female mice which have never been exposed to testicular secretions.

In vitro antileukemic, antioxidant and prooxidant activities of Antoksyd S (C/E/XXI): a comparison with baicalin and baicalein.  

PubMed

There is increasing interest concerning the use of natural antioxidants as low toxic antileukemic compounds. Antoksyd S (C/E/XXI), is a novel herbal drug derived in Poland from the powdered roots of Scutellaria baicalensis, and the biological activities of its major components (baicalin and baicalein) were compared on the human leukemia cell line HL-60. On MTT assay, Antoksyd S (C/E/XXI) showed an obvious cytotoxic effect on HL-60 cells, which was compared with those caused by cisplatin and doxorubicin under the same experimental conditions. A comparative assay of the antioxidative and prooxidative capacity of Antoksyd S (C/E/XXI) was also undertaken using two different reactive species: superoxide (O2-) and a transition metal (Cu2+). Antoksyd S (C/E/XXI) has low toxicity, acting as a modifier of HL-60 cells proliferation and as an antioxidant, which could act prooxidatively in the presence of transition metal ions. Taken together, it seems reasonable to suggest that Antoksyd S (C/E/XXI) as compared to baicalin and baicalein, or to the cytostatics cisplatin and doxorubicin, might be an especially good candidate for the future development of new therapeutic techniques, alone or in "combination treatment regimens", to enhance leukemia cell killing.

Trafficking activity of myosin XXI is required in assembly of Leishmania flagellum.  

PubMed

Actin-based myosin motors have a pivotal role in intracellular trafficking in eukaryotic cells. The parasitic protozoan organism Leishmania expresses a novel class of myosin, myosin XXI (Myo21), which is preferentially localized at the proximal region of the flagellum. However, its function in this organism remains largely unknown. Here, we show that Myo21 interacts with actin, and its expression is dependent of the growth stage. We further reveal that depletion of Myo21 levels results in impairment of the flagellar assembly and intracellular trafficking. These defects are, however, reversed by episomal complementation. Additionally, it is shown that deletion of the Myo21 gene leads to generation of ploidy, suggesting an essential role of Myo21 in survival of Leishmania cells. Together, these results indicate that actin-dependent trafficking activity of Myo21 is essentially required during assembly of the Leishmania flagellum. PMID:20501700

Positive effects of short course androgen therapy on the neurodevelopmental outcome in boys with 47,XXY syndrome at 36 and 72 months of age.  

PubMed

The effects of early androgen treatment on neurodevelopmental performance in pre-pubertal boys with 47,XXY have not been well investigated. The influence of hormones on brain development in humans suggests that a positive effect on neurodevelopmental outcome in young boys with XXY may be plausible with hormone replacement therapy. The aim of the study was to investigate retrospectively if an early course of androgen treatment (three injections of testosterone enanthate, 25 mg, each) had an impact on specific domains of neurodevelopmental function in boys with 47,XXY at 36 and 72 months of age. One hundred one boys with a karyotype of 47,XXY had neurodevelopmental assessments. The retrospective chart review resulted in one group (n = 34) who had received androgen treatment during infancy and the second group was untreated (N = 67). Statistical analysis was completed to determine if there was a positive effect from treatment observed at 36 and at 72 months on multiple domains of development. There were significant differences in multiple cognitive domains in the group who received androgen treatment, including multiple measures of language, intellectual, and neuromotor skills. Improved function was observed in neurodevelopmental outcome in boys with 47,XXY at 36 and 72 months who had been treated with a short course of androgen treatment in infancy. Continued research is underway to expand our understanding of the relationship of androgen, brain function, and neurobehavioral and neurodevelopmental outcome in boys with 47,XXY. PMID:23345253

Communication strategy of transboundary air pollution findings in a US-Mexico Border XXI program project.  

PubMed

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.

Participants included males with XXY (N=102, M=10.08 years), XYY (N=40, M=9.93 years), and XXYY (N=32, M=11.57 years). XXY had lower (better) SRS scores compared to XYY and XXYY. Scores were not significantly different between XYY and XXYY. In all groups, there were significantly more with SRS scores in the severe range compared to the SRS normative sample. All groups scored lowest (better) on Social Motivation. Relationships between SRS scores and demographic and clinical variables were examined. Results describe the social skills in males with SCA, and suggest that an additional Y chromosome may contribute to increased risk of autistic behaviors.

Attention-Deficit Hyperactivity Disorder Symptoms in Children and Adolescents with Sex Chromosome Aneuploidy: XXY, XXX, XYY, and XXYY  

PubMed Central

Objective Attentional problems, hyperactivity, and impulsivity have been described as behavioral features associated with sex chromosome aneuploidy (SCA). In this study, the authors compare attention-deficit hyperactivity disorder (ADHD) symptoms in 167 participants aged 6 to 20 years with 4 types of SCA (XXY n = 56, XYY n = 33, XXX n = 25, and XXYY n = 53). They also evaluate factors associated with ADHD symptomatology (cognitive and adaptive scores, prenatal vs postnatal ascertainment) and describe the clinical response to psychopharmacologic medications in a subset of patients treated for ADHD. Methods Evaluation included medical and developmental history, cognitive and adaptive functioning assessment, and parent and teacher ADHD questionnaires containing DSM-IV criteria. Results In the total study group, 58% (96/167) met DSM-IV criteria for ADHD on parent-report questionnaires (36% in XXY, 52% in XXX, 76% in XYY, and 72% in XXYY). The Inattentive subtype was most common in XXY and XXX, whereas the XYY and XXYY groups were more likely to also have hyperactive/impulsive symptoms. There were no significant differences in Verbal, Performance, or Full Scale IQ between children with symptom scores in the ADHD range compared with those below the ADHD range. However, adaptive functioning scores were significantly lower in the group whose scores in the ADHD range were compared with those of the group who did not meet ADHD DSMIV criteria. Those with a prenatal diagnosis of XXY were less likely to meet criteria for ADHD compared with the postnatally diagnosed group. Psychopharmacologic treatment with stimulants was effective in 78.6% (66/84). Conclusions Children and adolescents with SCA are at increased risk for ADHD symptoms. Recommendations for ADHD evaluation and treatment in consideration of other aspects of the SCA medical and behavioral phenotype are provided.

Cyberwar XXI: quantifying the unquantifiable: adaptive AI for next-generation conflict simulations  

NASA Astrophysics Data System (ADS)

The era of the "Revolution in Military Affairs," "4th Generation Warfare" and "Asymmetric War" requires novel approaches to modeling warfare at the operational and strategic level of modern conflict. For example, "What if, in response to our planned actions, the adversary reacts in such-and-such a manner? What will our response be? What are the possible unintended consequences?" Next generation conflict simulation tools are required to help create and test novel courses of action (COA's) in support of real-world operations. Conflict simulations allow non-lethal and cost-effective exploration of the "what-if" of COA development. The challenge has been to develop an automated decision-support software tool which allows competing COA"s to be compared in simulated dynamic environments. Principal Investigator Joseph Miranda's research is based on modeling an integrated military, economic, social, infrastructure and information (PMESII) environment. The main effort was to develop an adaptive AI engine which models agents operating within an operational-strategic conflict environment. This was implemented in Cyberwar XXI - a simulation which models COA selection in a PMESII environment. Within this framework, agents simulate decision-making processes and provide predictive capability of the potential behavior of Command Entities. The 2003 Iraq is the first scenario ready for V&V testing.

Psychophysiological Markers of Vulnerability to Psychopathology in Men with an Extra X Chromosome (XXY)  

PubMed Central

Studying genetically defined syndromes associated with increased risk for psychopathology may help in understanding neurodevelopmental mechanisms related to risk for psychopathology. Klinefelter syndrome (47,XXY) is one of the most common sex chromosomal aneuploidies (1 in 650 male births) and associated with increased vulnerability for psychopathology, including psychotic symptoms. Yet, it remains unknown whether this increased risk is associated with underlying psychophysiological mechanisms that are typically deficient in individuals with psychotic disorders. The present study assessed three “classic” psychophysiological markers of psychosis in Klinefelter syndrome (KS): smooth pursuit eye movements (SPEM), prepulse inhibition (PPI) and P50 suppression. Fourteen adults with KS and 15 non-clinical adults participated in the study. Data on SPEM (reflecting visuo-motor control) as well as PPI and P50 suppression (reflecting sensory gating) were collected. Dysfunctions in SPEM were observed in individuals with KS, with less smooth pursuit as expressed in lower position gain. Also, reduced sensory gating in individuals with KS was suggested by significantly reduced prepulse inhibition of the startle response (PPI) (effect size 1.6). No abnormalities were found in suppression of the P50 (effect size 0.6). We speculate that impairments in these psychophysiological mechanisms may reflect core brain dysfunctions that may also mediate the described increased vulnerability for psychotic symptoms in KS. Although speculative, such deficit specific, rather than disorder specific, psychophysiological dysfunctions in KS might convey vulnerability to other types of psychopathology as well. As KS already can be diagnosed prenatally, the predictive value of childhood impairments in prepulse inhibition and smooth pursuit for development of psychopathology later in life could be assessed. In sum, studying individuals with KS may prove to be an avenue of research leading to new hypotheses and insights into “at risk” pathways to psychopathology.

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].

Among major achievements of medicine in XX-early XXI centuries considered as the most outstanding contribution are the development of theory of system of control of functions of organism and its integrity by I.P. Pavlov and his disciples and followers: the concept of psycho-somatic medicine by Z. Freud and social psychology; the theory of stress and general adaptive syndrome by H. Selye and the discovering of nature of many infectious and parasitic diseases. Then establishment of pathogenic impact of extra-environmental factors, decoding of gene chromosomal structure of organism, development of genetic engineering, effective pharmaceuticals, and techniques of treatment and prevention of various inherent and acquired diseases also can be put into this category. The achievements and discoveries in the area of public health, social medicine and hygiene and development of concept of healthy life-style are discussed too. PMID:23350086

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.

An extra X or Y chromosome: contrasting the cognitive and motor phenotypes in childhood in boys with 47,XYY syndrome or 47,XXY Klinefelter syndrome  

PubMed Central

Objective The goal of this study was to contrast the cognitive phenotypes in boys with 47,XYY (XYY) karyotype and boys with 47,XXY karyotype (Klinefelter syndrome, KS), who share an extra copy of the X-Y pseudoautosomal region but differ in their dosage of strictly sex-linked genes. Methods Neuropsychological evaluation of general cognitive ability, language, memory, attention, visual-spatial abilities, visual-motor skills, and motor function. Results Study cohort: 21 boys with 47,XYY and 93 boys with 47,XXY (KS), ages 4-17 years, and 36 age-matched control boys. Both the XYY and KS groups performed less well, on average, than the controls on tests of general cognitive ability, achievement, language, verbal memory, some aspects of attention and executive function, and motor function. The boys with XYY on average had more severe and pervasive language impairment, at both simple and complex levels, and the boys with KS on average had greater motor impairment in gross motor function and coordination, especially in running speed and agility. Conclusions The results from these large XYY and KS cohorts have important neurocognitive and educational implications. From the neurocognitive standpoint, the presenting findings afford an opportunity to gain insights into brain development in boys with XYY and those with KS. From the educational standpoint, it is critical that boys with XYY or KS receive appropriate educational interventions that target their specific learning challenges. These findings also provide important information for counseling clinicians and families about these disorders.

Andaman-Sumatra island arc: II. The December 26, 2004 earthquake as one of the key episodes in seismogenic activation of the arc in the beginning of XXI century  

NASA Astrophysics Data System (ADS)

The interpretation of the nature and parameters of the source for the earthquake that occurred in Sumatra on December 26, 2004 is suggested. Our study relies on a variety of data on the geological structure of the region, long-term seismicity, spatial distribution of the foreshocks and aftershocks, and focal mechanisms; and the pattern of shaking and tsunami, regularities in the occurrence of the earthquakes, and the genetic relationship between the seismic and geological parameters inherent in various types of seismogenic zones including island arcs. The source of the Sumatran earthquake is a steep reverse fault striking parallel to the island arc and dipping towards the ocean. The length of the fault is ˜450 km, and its probable bedding depth is ˜70-100 km. The magnitude of this seismic event corresponding to the length of its source is 8.9-9.0. The vertical displacement in the source probably reached 9-13 m. The fault is located near the inner boundary of the Aceh Depression between the epicenter of the earthquake and the northern tip of the depression. The strike-slip and strike-slip reverse the faults cutting the island arc form the northern and southern borders of the source. The location and source parameters in the suggested interpretation account quite well for the observed pattern of shaking and tsunami. The Aceh Depression and its environs probably also host other seismic sources in the form of large reverse faults. The Sumatran earthquake, which was the culmination of the seismogenic activation of the Andaman-Sumatra island arc in the beginning of XXI century, is a typical tsunamigenic island-arc earthquake. By its characteristics, this event is an analogue to the M W = 9 Kamchatka earthquake of November 4, 1952. The spatial distribution of the epicenters and the focal mechanisms of the aftershocks indicate that the repeated shocks during the Sumatran event were caused by the activation of a complex system of geological structures in various parts of the island arc and Andaman Sea instead of the slips on a single rupture (a subduction thrust about 1200-1300 km in length).

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.

Alfabetización astronómica  

NASA Astrophysics Data System (ADS)

A fines de 1991, en una revista de educación en ciencias, José L. Sérsic reflexionaba acerca de los problemas que enfrentaría la enseñanza de los conocimientos astronómicos en nuestro país, en los umbrales del Siglo XXI. Entonces postulaba como un objetivo mínimo, que los jóvenes deberían mostrar signos claros de que se hallan astronómicamente alfabetizados. Era el año en que se realizaba por primera vez una Asamblea General de I.A.U. en Buenos Aires, una oportunidad de singulares características para la comunidad astronómica local y, simultáneamente el comienzo de un cambio radical en la estructura del sistema educativo argentino. ?`Contempla ese cambio el objetivo que postulara Sérsic? ?`Estamos en condiciones de afirmar que estamos en camino de lograrlo? ?`Con qué parámetros?. Presentamos aquí un panorama general sobre algunas de las acciones realizadas en función de alcanzar esa alfabetización científica, analizando exclusivamente la actividad de enseñanza hasta el nivel universitario, sin detenernos en el mismo, ya que lo consideramos una instancia superior e independiente de aquella alfabetización. Tampoco nos referiremos a la tarea de difusión, divulgación o popularización de la Astronomía, ya que su condición de asistemática y subjetiva no es evaluable en términos de la formación integral de un individuo.

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.

At the XIV Workshop on the Development and Function of the Reproductive Organs held at the Congress Centre of the University of Rome Tor Vergata, Monteporzio Catone, Rome, Italy, the introduction to the first session entitled Mammalian primordial germ cells dedicated to the memory of Anne McLaren, was the occasion for a concise review of the state of art of research on the biology of primordial germ cells (PGCs). This great, unforgettable scientist, who died in a car accident in July 2007, dedicated most of her studies to this field over the last 25 years. Topics briefly reviewed in this Meeting Report are: 1) how the germ line is determined; 2) what are the mechanisms underlying PGC migration; 3) to what extent PGC survival, proliferation and differentiation are cell autonomous or environmentally controlled processes and 4) how the potential for totipotency is retained in PGCs.

The radical reform of health care system in Georgia after the collapse of the Soviet Union negatively affected the occupational medicine, environmental medicine, occupational health services, and preventive measures. The level of medical assistance to people suffering from harmful industrial factors decreased, which is a serious danger for the health of the workers and for the next generations. The aim of the article is to protect the right to means for adequate health and suggest effective ways for health care improvement. In order to reconstruct the system of Occupational and Environmental Medicine, it is necessary to create a network of occupational healthcare. We strongly believe investment in preventive health is vital to safeguard and improve the health of the community. The Center of Occupational Medicine and the Institute of Labor Medicine and Ecology with corresponding financing, educational programs for medical students and continuous practice of physicians in occupational medicine, enhancing the number of the scientific research designed to discover the early forms of occupational pathologies and timely prevention of the disease is vital to protect the right to means for adequate health, to advance the professional development of physicians, nurses, research scientists, and allied health professionals in order to diminish general and occupational diseases in Georgia.

Oral Histories in Meteoritics and Planetary Science—XXI: Donald Burnett  

NASA Astrophysics Data System (ADS)

In this interview, Donald Burnett (Fig. 1) describes how he applied to the University of Chicago, with considerable support from his father, where he took classes from Harold Urey and was inspired by Ed Anders to pursue a career in nuclear chemistry and, later, cosmochemistry. As a graduate student at the University of California at Berkeley, Don learned to use charged-particle tracks as a detector for radioactive nuclei, a technique that he applied to a wide variety of problems over the next 20 years, including the neutron profile probe that was deployed on the Moon. After a one-year postdoc with William Fowler at the California Institute of Technology, he became involved with Jerry Wasserburg, who ultimately obtained a faculty position for him in the Geology Division. Since then, Don has worked on a number of fundamental problems in cosmochemistry, chronology of the solar system, the initial Pu/U abundance, fractionation of U and Pu in igneous processes, and elemental abundances. This last interest led him to advocate, propose, and lead the Genesis space mission to collect and return samples of the solar wind. The crash of the return capsule caused alarm, but some aspects of the mission were unaffected and others have been successfully handled, so that several major new results have been published: the lack of an SEP component in lunar samples, the Ne and Ar composition of the solar wind, and, most importantly, the oxygen and nitrogen isotopic composition of the Sun. Don received the Leonard Medal in 2012.

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.

Isoleucine and Valine Metabolism in Escherichia coli XXI. Mutations Affecting Derepression and Valine Resistance  

PubMed Central

The activity of acetohydroxy acid isomeroreductase, an essential enzyme for isoleucine and valine biosynthesis in Escherichia coli, was examined in a series of mutants containing derepressed levels of acetohydroxy acid synthetase activity but which differed from each other in the sensitivity of the synthetases to valine inhibition. The finding that isomeroreductase was highest in the strain with the synthetase that was least sensitive to valine inhibition supported the model of internal induction of the isomeroreductase by its acetohydroxy acid substrates. The mutation leading to the acetohydroxy acid synthetase least sensitive to valine was found to be unlinked to the ilv gene cluster and appeared to result in a synthetase that differed from the normal enzyme in several properties. The locus of this mutation is designated ilvF. The loci leading to derepression were designated azl. A pleiotropic, apparently single-step, mutation was found that led to restoration of end-product sensitivity to the synthetase, loss of end-product sensitivity of threonine deaminase [EC 4.2.1.16, l-threonine hydro-lyase (deaminating) and loss of isomeroreductase activity.

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.

Dialysis in the elderly patient: a challenge of the XXI century--narrative review.  

PubMed

With the increase in life expectancy, the improvement of therapeutic arsenal, knowledge and control of chronic degenerative diseases, the world population has reached older age groups. As advanced age is a risk factor for chronic kidney disease (CKD), along with the bonus of increased survival, today we are experiencing the greatest burden of progressive incidence of elderly patients on renal replacement therapy (RRT). Dialysis in elderly patients, which for three decades was considered out of question, today is a routine for nephrologists, who face the challenge of providing care to elderly patients with CKD stage 5 with dialysis indication. In fact, what we see nowadays are dialysis incidents elderly patients as the fastest growing group on RRT. Although without reaching a consensus, it seems indisputable that for elderly patients with CKD, the most important is the quality of life. In this paper we discuss the dialysis in the elderly patient. PMID:23812571

[Eating disorders: Considerations on nosology, etiology and treatment in the XXI century].  

PubMed

Amazing advances have been made in medical sciences since the first international conference on eating disorders (ED) was held in the 1970s, and there have been remarkable changes in the field of ED itself. Back then, virtually all that was talked about was anorexia nervosa; clinicians and researchers were mainly concerned about the possible hypothalamic and endocrine factors that seemed to be involved and there had been no epidemiological studies or controlled trials with psychiatric drugs or psychotherapy. Although the picture today is quite different, there are still significant gaps which even affect the classification of these disorders, as well as their neurobiological bases and both the pharmacological and psychological treatments which should be used. This paper gives a brief summary of these gaps and discusses the need to find endophenotypes which may help in categorising and directing research into these disorders. Mention is made of possible contributions from other fields for the benefit of greater progress in understanding eating disorders. Specific reference is made to the addictive model, out of which neuropsychology and animal models may provide data transferable to our area of expertise. Lastly, the current state of ED treatment is discussed with pointers as to from what perspective it would be most useful to seek improvements. PMID:22854615

Chelation in metal intoxication XXI: chelation in lead intoxication during vitamin B complex deficiency  

SciTech Connect

The vitamin B-complex deficiency increases the vulnerability to neuro- and systemic toxicity of Pb in young rats. Thus, the nutritional status of vitamins like that of protein or minerals seems to influence the etiology of Pb toxicity and may be expected to affect the response toward Pb chelators. 2,3 dimercaptosuccinic acid (DMSA) and N-(2-hydroxyethyl) ethylene-diamine triacetic acid (HEDTA) have been found to be effective antidotes to Pb intoxication. In the present study, these selective metal chelating agents were compared for their ability to reduce the body burden of Pb and restore the altered biochemical parameters in young developing Pb intoxicated rats maintained on normal or vitamin B-complex deficient diet. The investigation was aimed to suggest suitable prophylaxis of Pb poisoning prevalent among children who may also be suffering from vitamin deficiency in developing and poor countries.

Infant hearing loss: from diagnosis to therapy Official Report of XXI Conference of Italian Society of Pediatric Otorhinolaryngology.  

PubMed

Hearing loss is one of the most common disabilities and has lifelong consequences for affected children and their families. Both conductive and sensorineural hearing loss (SNHL) may be caused by a wide variety of congenital and acquired factors. Its early detection, together with appropriate intervention, is critical to speech, language and cognitive development in hearing-impaired children. In the last two decades, the application of universal neonatal hearing screening has improved identification of hearing loss early in life and facilitates early intervention. Developments in molecular medicine, genetics and neuroscience have improved the aetiological classification of hearing loss. Once deafness is established, a systematic approach to determining the cause is best undertaken within a dedicated multidisciplinary setting. This review addresses the innovative evidences on aetiology and management of deafness in children, including universal neonatal screening, advances in genetic diagnosis and the contribution of neuroimaging. Finally, therapy remains a major challenge in management of paediatric SNHL. Current approaches are represented by hearing aids and cochlear implants. However, recent advances in basic medicine which are identifying the mechanisms of cochlear damage and defective genes causing deafness, may represent the basis for novel therapeutic targets including implantable devices, auditory brainstem implants and cell therapy.

Studies on phenolic steriods in human subjects. XXI. renal metabolism, conjugation and excretion of four androgens: a comparison with estriol.  

PubMed

The present study was conducted in order to ascertain whether the human kidney can conjugate androgens to an extent similar to that of estriol (E3). Differently labeled androgens (testosterone, DHT and androstenedione) were injected simultaneously into a peripheral vein and the renal artery. The excretion of the radioactivity in the early urine collections served as an index of the ability of the kidney to conjugate and/or metabolize the various steroids administered. It was shown that the human kidney can conjugate testosterone to some extent as the 17-glucuronide of DHT, but to a much lesser degree that E3. Androstenedione was not conjugated by the kidney and the excretion DHT was paradoxically lower following its renal artery administration than following its peripheral injection. We interpret the latter to indicate that some kidney cells may contain receptors with very high affinity for DHT, thus leading to the lower excretion observed. The administration of androstenediol (into the renal artery) and E3 (peripherally) indicated that the diol was not conjugated as readily as E3. The results point to the ability of the kidney to conjugate testosterone to some extent; however, in no case was it able to conjugate an androgen with the same facility as it does E3. PMID:194910

The paper starts with a brief discussion of the traditional peer review (TPR) system of research evaluation, its role, and the criticisms levelled at it. An analysis of specific problems in economics leads to a full discussion of the Open Peer Review (OPR) system developed by the World Economics Association (WEA) and the principles behind it. The system is open in the following two respects: (a) disclosure of names of authors and reviewers; and (b) inclusivity of potential reviewers in terms of paradigmatic approaches, country, and community. The paper then discusses the applicability of the same system to other disciplines. In doing so, it stressed the aims of various evaluation systems and the possible pitfalls of rating systems. It also speculates on the future of journal publication.

Investigaccion-accion en la sala de clases sobre las creencias de la cultura de la ciencia de un grupo de estudiantes universitarios y su relacion reciproca con el aprendizaje de las ciencias biologicas  

NASA Astrophysics Data System (ADS)

La investigacion---accion que se llevo a cabo en la sala de clases tenia como punto de partida las creencias de la cultura de la ciencia de un grupo de estudiantes universitarios para luego examinar sus implicaciones en el proceso de aprendizaje de las Ciencias Biologicas. ¿Que se supone que hagan las creencias en relacion con el aprendizaje? ¿En que consiste incorporar este aspecto a la practica educativa universitaria? Utilizando el modelo de Kemmis y McTaggart (1987) la investigacion-accion se planteo como un proceso dinamico en cuatro momentos en espiral constituidos por la planificacion, la accion, la observacion y la reflexion. Cada una de las fases tuvo una intencion retrospectiva y prospectiva formando una espiral de autorreflexion del conocimiento y la accion. Se llevaron a cabo audio grabaciones en clases y analisis de documentos. Ademas, la profesora-investigadora hizo un portafolio para reflexionar sobre las creencias de la cultura de la ciencia que tienen los estudiantes y las creencias del aprendizaje que tiene la profesora y sobre como la comprension de estos elementos ayudo a mejorar su practica educativa a traves del tiempo. Los resultados obtenidos apuntan a que las creencias de la cultura de la ciencia que tiene el grupo de estudiantes son diversas. Ellos si creen que la ciencia tiene una cultura la cual describieron como: complicada y desconocida que evoluciona constantemente, que es un conjunto de metodos, que es altamente tecnologica, que resuelve problemas de salud, ayuda a interpretar la realidad del mundo que los rodea y su origen y que existen unas intersecciones entre la ciencia y el poder. Sobre las creencias del proceso de aprendizaje de la profesora-investigadora, estas senalan que el modelaje de actores, la vision de la academia que tiene ella asi como la participacion y negociacion entre todos los involucrados en el proceso educativo, son factores que inciden en el proceso de aprendizaje.

Impacts of climate change on ground level gas-phase pollutants and aerosols in the Iberian Peninsula for the late XXI century  

NASA Astrophysics Data System (ADS)

Climate change alone influences future air pollution levels through modifications of gas-phase chemistry, transport, removal, and natural emissions. Hence, the goal of this study is to determine at what extent concentrations of air pollutants respond to changes over the Iberian Peninsula under a climate change scenario. The methodology includes the use of the regional modeling system MM5 (regional climate model version)-CHIMERE for two nested domains covering Europe and the Iberian Peninsula. Two time slices driven by ECHO-G global circulation model covering from 1991 to 2010 and 2071 to 2100 under the SRES A2 scenario have been compared. Climate change influences the concentrations of both gas-phase pollutants and aerosols through changes in temperature, precipitation, mixing height, transport, humidity, and oxidant levels. The trends of variation of ozone (changes up to 5 ppb, +10% increase during summertime) and aerosols over southwestern Europe are influenced by the higher mean temperature modeled for the future climate (up to +5.4 K), since it favors the formation of secondary gas-phase products. It also enhances sulphates (+2 ?g m-3) and secondary organic aerosols (SOA) (+2.5 ?g m-3 under SRES A2 scenario) and contributes to the decomposition of ammonium nitrate, remaining in the gas phase. Further, the 17% percent decrease of precipitation modeled for 2071-2100 has a strong effect in the frequency of the washout and therefore in the levels of natural aerosols: the concentrations of aerosols decrease with increasing precipitation as wet deposition provides the main aerosol sink.

THE SOLAR NEIGHBORHOOD. XXI. PARALLAX RESULTS FROM THE CTIOPI 0.9 m PROGRAM: 20 NEW MEMBERS OF THE 25 PARSEC WHITE DWARF SAMPLE  

SciTech Connect

We present accurate trigonometric parallaxes for 20 new members of the 25 pc white dwarf (WD) sample as part of the Discovery and Evalution of Nearby Stellar Embers (DENSE) project.{sup 7} http://www.DenseProject.com Previously, there were a total of 112 WD systems with trigonometric parallaxes placing them within 25 pc and of these, 99 have trigonometric parallaxes known to better than 10%. Thus, the 20 new members presented in this work represent a 20% increase in the number of WDs accurately known to be within 25 pc. In addition, we present updated parallaxes for seven known WDs within 10 pc that have been observed as part of the Astrometric Search for Planets Encircling Nearby Stars initiative to monitor nearby southern red dwarfs and WDs for astrometric perturbations from unseen companions. Including a few WD companions and WDs beyond 25 pc, we present a total of 33 trigonometric parallaxes. We perform atmospheric modeling for WDs to determine physical parameters (i.e., T {sub eff}, log g, mass, and WD age). Finally, a new ZZ Ceti pulsating WD was identified and revised constraints are placed on two mixed H/He atmosphere cool WDs that display continuum absorption in the near-infrared.

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.

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.

Properties and nature of Be stars. XXI. The long-term and the orbital variations of V832 Cyg = 59 Cyg  

NASA Astrophysics Data System (ADS)

An analysis of numerous homogenized UBV photoelectric observations and red spectra of the Be star V832 Cyg from several observatories led to the following principal findings: 1. Pronounced long-term light and colour variations of V832 Cyg result from a combination of two effects: from the gradual formation of a new Be envelope, and from an asymmetry and a slow revolution of the envelope (or its one-armed oscillation). The colour variations associated with the envelope formation are characterized by a positive correlation between brightness and emission strength, typical for stars which are not seen roughly equator-on. 2. The V magnitude observations prewhitened for the long-term changes follow a sinusoidal orbital light curve with a small amplitude and a period of 28.1971d which is derived from observations spanning 43 years. This independently confirms a 12-year old suggestion that the star is a spectroscopic binary with a 29-d period. V832 Cyg thus becomes the fifth known Be star with cyclic long-term V/R variations, the duplicity of which has been proven, the four other cases being ? Tau, V923 Aql, ? Cas and X Per. Therefore, the hypothesis that the long-term V/R variations may arise due to the attractive force of the binary companion at certain phases of the envelope formation is still worth considering as a viable alternative to the model of one-armed oscillation. 3. We have shown that the RV and V/R variations of the H? and He I 6678 emission lines are all roughly in phase. In particular, the He I 6678 emission also moves with the Be primary which differs from what was found for another Be binary, \\varphi Per. 4. We derived the orbital elements and found that in spite of the remaining uncertainties, the basic physical properties of the 28.2d binary are well constrained. 5. The light minimum of the orbital light curve occurs at elongation when the Be star is approaching us and the object becomes bluest in (B-V) and reddest in (U-B) at the same time. This may indicate that a part of the optically thick regions of the envelope is eclipsed at these orbital phases.

Estudio de la estructura logica utilizada en la ensenanza y el aprendizaje de los conceptos sobre el comportamiento de gases en el curso introductorio de quimica a nivel universitario  

NASA Astrophysics Data System (ADS)

El estudio que se presenta es de caracter cualitativo, un estudio multicasos donde se estudia la estructura logica utilizada por cuatro (4) profesores universitarios que ensenan el curso introductorio de quimica, en la planificacion, presentacion y evaluacion del tema sobre el comportamiento de los gases. Se utilizaron varias fuentes de informacion como: cuestionarios de profesores y estudiantes, entrevistas, grabaciones videomagnetofonicas, materiales didacticos y una prueba conceptual, entre otros. La informacion recopilada fue analizada de acuerdo al orden logico del contenido presentado, el estilo de ensenanza del profesor, las tecnicas y estrategias utilizadas para el desarrollo de destrezas de pensamiento, el ambiente fisico en el salon de clase y los instrumentos de evaluacion y avaluo. El estudio demuestra que lo que los profesores piensan y planifican para hacer sus presentaciones no necesariamente es lo que ocurre en el salon de clases. El desarrollo de destrezas de pensamiento, que constituye una prioridad de los profesores, no se elaboran efectivamente. El uso de las estrategias de resolucion de problemas numericos predomino. La participacion del estudiante en el salon de clases fue limitada y no se logro demostrar el desarrollo de las destrezas de pensamiento deseadas. Aunque los profesores tienen su propio estilo de ensenanza, el orden logico del contenido presentado en clase fue el mismo o siguio muy de cerca el orden establecido por el libro de texto. Los profesores utilizaron preferentemente la tiza y la pizarra para sus presentaciones y la dinamica en el salon de clases fue esencialmente tradicional. Los profesores hicieron su presentacion y los estudiantes copiaron pasivamente la informacion. Las evaluaciones de los estudiantes fueron esencialmente, pruebas escritas de seleccion multiple de acuerdo con el estilo en que se les enseno. El avaluo fue casi inexistente. La prueba conceptual administrada revela un aprendizaje pobre en los conceptos mas basicos sobre el comportamiento de los gases. El estudio senala que la ejecutoria del profesor en todos los aspectos de la ensenanza y el aprendizaje es un factor clave que debe darsele prioridad. Se recomienda que el profesor, en general, tenga un conocimiento basico de las teorias de aprendizaje, de los factores que afectan el aprendizaje y las tecnicas y estrategias mas efectivas en el desarrollo de destrezas de pensamiento entre sus estudiantes. La estructura de la disciplina debe incluir tanto lo experimental como lo teorico.

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.

Stress Responses in Alfalfa (XXI. Activation of Caffeic Acid 3-O-Methyltransferase and Caffeoyl Coenzyme A 3-O-Methyltransferase Genes Does Not Contribute to Changes in Metabolite Accumulation in Elicitor-Treated Cell-Suspension Cultures).  

PubMed Central

Transcription of genes encoding L-phenylalanine ammonia-lyase (PAL), the first enzyme of the phenylpropanoid pathway, and caffeic acid 3-O-methyltransferase (COMT) and caffeoyl CoA 3-O-methyltransferase (CCOMT), enzymes involved in the synthesis of lignin and wall-esterified phenolic compounds, was strongly activated in elicitor-treated cell-suspension cultures of alfalfa (Medicago sativa L.). However, consequent changes in the extractable activities of COMT and CCOMT were small to nonexistent compared with a 15- to 16-fold increase in PAL activity. Only low levels of COMT and CCOMT transcripts were reflected in the total and polysomal RNA fractions compared with PAL transcripts. Elicited cell cultures did not accumulate lignin or the products of COMT and CCOMT in the soluble and wall-esterified phenolic fractions. In one alfalfa cell line in which elicitation resulted in very high PAL activity and increased deposition of methoxyl groups in the insoluble wall fraction, there was still no change in COMT and CCOMT activities. Overall, these results indicate that the initial gene transcription events in elicited cells may be less selective than the subsequent metabolic changes, highlighting the importance of posttranscriptional events in the control of phenylpropanoid biosynthesis.

Transiting exoplanets from the CoRoT space mission. XXI. CoRoT-19b: a low density planet orbiting an old inactive F9V-star  

NASA Astrophysics Data System (ADS)

Context. Observations of transiting extrasolar planets are of key importance to our understanding of planets because their mass, radius, and mass density can be determined. These measurements indicate that planets of similar mass can have very different radii. For low-density planets, it is generally assumed that they are inflated owing to their proximity to the host-star. To determine the causes of this inflation, it is necessary to obtain a statistically significant sample of planets with precisely measured masses and radii. Aims: The CoRoT space mission allows us to achieve a very high photometric accuracy. By combining CoRoT data with high-precision radial velocity measurements, we derive precise planetary radii and masses. We report the discovery of CoRoT-19b, a gas-giant planet transiting an old, inactive F9V-type star with a period of four days. Methods: After excluding alternative physical configurations mimicking a planetary transit signal, we determine the radius and mass of the planet by combining CoRoT photometry with high-resolution spectroscopy obtained with the echelle spectrographs SOPHIE, HARPS, FIES, and SANDIFORD. To improve the precision of its ephemeris and the epoch, we observed additional transits with the TRAPPIST and Euler telescopes. Using HARPS spectra obtained during the transit, we then determine the projected angle between the spin of the star and the orbit of the planet. Results: We find that the host star of CoRoT-19b is an inactive F9V-type star close to the end of its main-sequence life. The host star has a mass M? = 1.21 ± 0.05 M? and radius R? = 1.65 ± 0.04 R?. The planet has a mass of MP = 1.11 ± 0.06 MJup and radius of RP = 1.29 ± 0.03 RJup. The resulting bulk density is only ? = 0.71 ± 0.06 g cm-3, which is much lower than that for Jupiter. Conclusions: The exoplanet CoRoT-19b is an example of a giant planet of almost the same mass as Jupiter but a ?30% larger radius. The CoRoT space mission, launched on December 27, 2006, has been developed and is operated by the CNES, with the contribution of Austria, Belgium, Brazil, ESA (RSSD and Science Program), Germany and Spain. Partly based on observations obtained at the European Southern Observatory at Paranal, Chile in program 184.C-0639, and partly based on observations conducted at McDonald Observatory.

Sobre o uso das séries de Puiseux em mecanica celeste  

NASA Astrophysics Data System (ADS)

Neste trabalho é apresentada uma demonstração do uso dos diferentes desenvolvimentos em séries para as equações de perturbação em Mecânica Celeste no marco Hamiltoniano. Em trabalhos clássicos como os de Poincaré (Poincaré, 1893) por exemplo, já esta planteado o uso de potências não inteiras no pequeno parâmetro, o que evidencia a não analiticidade das funções quando uma ressonância ocorre. Nestes trabalhos os desenvolvimentos são na raíz quadrada da massa de Júpiter (o pequeno parâmetro). Mais recentemente (Ferraz-Mello, 1985) outros tipos de desenvolvimentos foram aplicados modificando substancialmente as ordens de grandeza e a velocidade de convergência das séries. Com esta abordagem, os desenvolvimentos foram expressados em termos da raíz cúbica do pequeno parâmetro. Neste trabalho apresentamos um enfoque geral, onde os diferentes tipos de desenvolvimentos em séries de Puiseux (Valiron, 1950) são obtidos a partir da aplicação de Teorema de Preparação de Weierstrass (Goursat, 1916) considerando a equação de Hamilton-Jacobi como uma equação algébrica. Os resultados são aplicados ao problema restrito dos três corpos em ressonância de primeira ordem e, dependendo da grandeza da excentricidade do asteróide em relação à de Júpiter, obtemos os diferentes desenvolvimentos, em raíz quadrada ou raíz cúbica da massa de Júpiter.

Such questions are of special interest for those who are concerned with both old and new problems found in the field that has come to be known as sexual and reproductive rights, with implications for the field of Public Health.

Conservación de material histórico sobre papel en el Observatorio Astronómico de la Universidad Nacional de Córdoba  

NASA Astrophysics Data System (ADS)

At the recently created Astronomical Museum ``Pte. Sarmiento - Dr. Benjamin Gould", the task of preventive conservation of historic documents has been faced. These materials include: 1) letters exchanged between national authorities and the directors of the Observatory, during the first decades (1870-1880-1890); b) original observation logs from these very first times, containing astrometrical and photometrical data; c) a variety of ancient books and papers; d) administrative documents. The state of conservation of this patrimony was varied: since well-conserved books and letters, to highly degraded logs. The observation logs written by B. Gould and the astronomers who followed him had been stocked in a safe with a permanent humidity of about 70 %, without any ventilation and exposed to the attack of insects of the family ``dermestidae." These conditions could not be worse for the conservation of paper. In order to stop the proccess of degradation and create a healthy environment for written-paper conservation, a team was formed with personnel belonging to the Cultural Area of the Municipality. The tasks being performed on the observation logs are: 1) an initial, mechanical cleaning, performed once the material is extracted from the contaminated safe: by these means, adult insects and pupas are removed 2) a stage of about two weeks of duration, in which the logs are mantained in a vacuum chamber, in orden to completely eliminate the adult, pupa and egg stage insects by anoxia 3) the final mechanical cleaning 4) storage in a clean location. In order to perform these tasks, we work in collaboration with the Environmental Observatory of the City, and the group of Material-Science Research of Fa.M.A.F. Regarding the letters, a mechanical cleaning was performed. After that, the letters were digitized by means of a scanner, inventoried, put inside acid-free polipropylene envelops and filed for conservation, protected from intense light and external sources of contamination. Copies of these letters will be included as exhibits.

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

Effects of sex chromosome aneuploidy on male sexual behavior  

PubMed Central

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.

Nuevos resultados sobre la cinemática global y nuclear de NGC 253: movimientos no circulares y emisión en Br ?  

NASA Astrophysics Data System (ADS)

Continuing with previous research (Camperi et al., BAAA, 54, 377, 2011), new heliocentric radial velocity distributions are presented for the nearby galaxy NGC 253, obtained from the ionized hydrogen recombination line H?. These distributions have been derived from long-slit spectroscopy for various position angles. It is also shown the heliocentric radial velocity distribution corresponding to part of the infrared data (ionized hydrogen recombination line Br?) observed with the Phoenix spectrograph of the Gemini South Observatory. Sequential mapping with the long slit using this instrument will enable to study in detail the kinematics of the galaxy's core, which is strongly obscured by dust. FULL TEXT IN SPANISH

Klinefelter's syndrome in adolescence.  

PubMed Central

Twelve boys with Klinefelter's syndrome (47,XXY) identified by sex chromatin screening at birth were examined at between ages 16 and 18 years, together with 12 controls matched for social class and birth order from the same newborn population. Physical examination, psychometric assessment, personality, and degree of psychosexual development were assessed without knowledge of the karyotype. Anthropometry showed increased leg length and decreased head circumference in the XXY boys. Gynaecomastia was present in 4 boys, and testicular volume was reduced in the majority but one boy had normal sized testes. On the Wechsler intelligence scale there was a significant reduction in verbal score but not in either performance or full-scale score compared with the controls. Although appreciable differences were found in growth, personality, intelligence test scores, and psychosexual development, these were of small degree.

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.

Spectrometer sensitivity calibration in the extreme uv by means of branching ratios of magnetic dipole lines  

SciTech Connect

Relative intensity measurements of various line pairs resulting from magnetic dipole transitions within the configurations s/sup 2/p/sup 2/ and s/sup 2/p/sup 4/, in conjunction with calculated transition probabilities, have been used to determine the wavelength dependence of the sensitivity of a grazing incidence spectrometer, in the range 400 to 1000 A. Emissions from Cr XIX, Fe XXI, Ni XXI and XXIII, Cu XXIV, and Zr XXVII ions in PLT tokamak discharges were used for this purpose. Absolute sensitivity of the spectrometer at selected wavelengths had been determined by the traditional hydrogen, helium, carbon, and oxygen electric-dipole line pairs from the same discharges. Similar attempts to use transitions in the s/sup 2/p/sup 3/ configurations in Cr XVIII, Zr XXVI, and Mo XXVIII ions resulted in significant discrepancies that are ascribed to uncertainties in the corresponding calculated transition probabilities.

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.

Recent wavelength measurements in 2- and 3- electron systems-a brief report-  

NASA Astrophysics Data System (ADS)

We present 3 recent precision measurements of the 1s2s 3S-1s2p 3P wavelengths in the helium-like, two-electron systems Li II, Ne IX and Ti XXI. We also comment on an old (1981) comparison between theory and experiment for the 1s22s 2S-1s22p 2P transition wavelengths in the lithium-like, three electron isoelectronic sequence.

Results of preimplantation genetic diagnosis in patients with Klinefelter's syndrome  

Microsoft Academic Search

With the application of preimplantation genetic diagnosis (PGD), a possible genetic contribution of spermatozoa obtained from 47,XXY non-mosaic Klinefelter patients on preimplantation embryos was analysed in eight couples. Interpretable fluorescence in-situ hybridization results were obtained for 28 out of 33 embryos biopsied (84.8%) and 23 blastomeres were analysed for chromosomes 13, 18, 21, X and Y. Nine out of 23
