    Perfect synchronicity in N-player games is a useful theoretical dream, but communication delays are inevitable and may result in asynchronous interactions. Some systems such as financial markets are asynchronous by design, and yet most theoretical models assume perfectly synchronized actions. We propose a general method to transform standard models of adaptive agents into asynchronous systems while preserving their global structure under some conditions. Using the minority game as an example, we find that the phase and fluctuations structure of the standard game subsists even in maximally asynchronous deterministic case, but that it disappears if too much stochasticity is added to the temporal structure of interaction. Allowing for heterogeneous communication speeds and activity patterns gives rise to a new information ecology that we study in details. in here

    During the last 4 decades, a rapid increase has occurred in the number of survey-based and epidemiological studies of the health profiles of adults in general and of the causes of disparities between majority and minority Americans in particular. According to these studies, healthful aging consists of the absence of disease, or at least of the most serious preventable diseases and their consequences, and findings consistently reveal serious African American and Hispanic disadvantages in terms of healthful aging. We (1) briefly review conceptual and operational definitions of race and Hispanic ethnicity, (2) summarize how ethnicity-based differentials in health are related to social structures, and (3) emphasize the importance of attention to the economic, political, and institutional factors that perpetuate poverty and undermine healthful aging among certain groups.

    The simian hemorrhagic fever virus (SHFV) genome differs from those of other members of the family Arterivirus in encoding two adjacent sets of four minor structural protein open reading frames (ORFs). A stable, full-length, infectious SHFV-LVR cDNA clone was constructed. Virus produced from this clone had replication characteristics similar to those of the parental virus. A subgenomic mRNA was identified for the SHFV ORF previously identified as 2b. As an initial means of analyzing the functional relevance of each of the SHFV minor structural proteins, a set of mutant infectious clones was generated, each with the start codon of one minor structural protein ORF mutated. Different phenotypes were observed for each ortholog of the pairs of minor glycoproteins and all of the eight minor structural proteins were required for the production of infectious extracellular virus indicating that the duplicated sets of SHFV minor structural proteins are not functionally redundant.

    Background Sexual minority youth are more likely to smoke cigarettes than heterosexuals but research into the determinants of these disparities is lacking. Purpose To examine whether exposure to structural stigma predicts cigarette smoking in sexual minority youth. Methods Prospective data from adolescents participating in the Growing Up Today Study (2000–2005). Results Among sexual minority youth, living in low structural stigma states (e.g., states with non-discrimination policies inclusive of sexual orientation) was associated with a lower risk of cigarette smoking after adjustment for individual-level risk factors (Relative Risk[RR]=0.97, 95% Confidence Interval[CI]: 0.96, 0.99, p=0.02). This association remained marginally significant after additional controls for potential state-level confounders (RR=0.97, 95% CI: 0.93, 1.00, p=0.06). In contrast, among heterosexual youth, structural stigma was not associated with past-year smoking rates, documenting specificity of these effects to sexual minority youth. Conclusions Structural stigma represents a potential risk factor for cigarette smoking among sexual minority adolescents. PMID:24136092

  7. Perceived Discrimination and Social Relationship Functioning among Sexual Minorities: Structural Stigma as a Moderating Factor

    Work on structural stigma shows how public policy affects health outcomes for members of devalued groups, including sexual minorities. In the current research, structural stigma is proposed as a moderating variable that strengthens deleterious associations between perceived discrimination and social relationship functioning. Hypotheses were tested in two cross-sectional studies, including both online (N = 214; Study 1) and community (N = 94; Study 2) samples of sexual minority men and women residing throughout the United States. Structural stigma was coded from policy related to sexual minority rights within each state. Confirming hypotheses, support for the moderating role of structural stigma was found via multilevel models across studies. Specifically, associations between perceived discrimination and friendship strain, loneliness (Study 1) and familial strain (Study 2) were increased for those who resided in states with greater levels of structural stigma and attenuated for those who resided in states with lesser levels. In Study 1, these results were robust to state-level covariates (conservatism and religiosity), but conservatism emerged as a significant moderator in lieu of structural stigma in Study 2. Results are discussed in the context of the shifting landscape of public policy related to sexual minority rights within the United States. PMID:26807046

    Stigma operates at multiple levels, including intrapersonal appraisals (e.g., self-stigma), interpersonal events (e.g., hate crimes), and structural conditions (e.g., community norms, institutional policies). Although prior research has indicated that intrapersonal and interpersonal forms of stigma negatively affect the health of the stigmatized, few studies have addressed the health consequences of exposure to structural forms of stigma. To address this gap, we investigated whether structural stigma-operationalized as living in communities with high levels of anti-gay prejudice-increases risk of premature mortality for sexual minorities. We constructed a measure capturing the average level of anti-gay prejudice at the community level, using data from the General Social Survey, which was then prospectively linked to all-cause mortality data via the National Death Index. Sexual minorities living in communities with high levels of anti-gay prejudice experienced a higher hazard of mortality than those living in low-prejudice communities (Hazard Ratio [HR] = 3.03, 95% Confidence Interval [CI] = 1.50, 6.13), controlling for individual and community-level covariates. This result translates into a shorter life expectancy of approximately 12 years (95% C.I.: 4-20 years) for sexual minorities living in high-prejudice communities. Analysis of specific causes of death revealed that suicide, homicide/violence, and cardiovascular diseases were substantially elevated among sexual minorities in high-prejudice communities. Strikingly, there was an 18-year difference in average age of completed suicide between sexual minorities in the high-prejudice (age 37.5) and low-prejudice (age 55.7) communities. These results highlight the importance of examining structural forms of stigma and prejudice as social determinants of health and longevity among minority populations.

    The tripeptide 1,2-dihydro-(3 H )-pyrrolo[3,2- e ]indole-7-carboxylate (CDPI3) binds to the minor groove of DNA with high affinity. When this minor groove binder is conjugated to the 5'-end of short oligonucleotides the conjugates form unusually stable hybrids with complementary DNA and thus may have useful diagnostic and/or therapeutic applications. In order to gain an understanding of the structural interactions between the CDPI3minor groove binding moiety and the DNA, we have determined and compared the solution structure of a duplex consisting of oligodeoxyribonucleotide 5'-TGATTATCTG-3' conjugated at the 5'-end to CDPI3 and its complementary strand to an unmodified control duplex of the same sequence using nuclear magnetic resonance techniques. Thermal denaturation studies indicated that the hybrid of this conjugate with its complementary strand had a melting temperature that was 30 degrees C higher compared with the unmodified control duplex. Following restrained molecular dynamics and relaxation matrix refinement, the solution structure of the CDPI3-conjugated DNA duplex demonstrated that the overall shape of the duplex was that of a straight B-type helix and that the CDPI3moiety was bound snugly in the minor groove, where it was stabilized by extensive van der Waal's interactions.

    To establish the basis of sequence-specific DNA recognition by HMG boxes we separately transferred the minor and major wings from the sequence-specific HMG box of TCF1 alpha into their equivalent position in the non-sequence-specific box 2 of HMG1. Thus chimera THT1 contains the minor wing (of 11 N-terminal and 25 C-terminal residues) from the HMG box of TCF1 alpha and the major wing (the 45 residue central section) from HMG1 box 2, whilst the situation is reversed in chimera HTH1. The structural integrity of the two chimeric proteins was established by CD, NMR and their binding to four-way junction DNA. Gel retardation and circular permutation assays showed that only chimera THT1, containing the TCF1 alpha minor wing, formed a sequence-specific complex and bent the DNA. The bend angle was estimated to be 59 degrees for chimera THT1 and 52 degrees for the HMG box of TCF1 alpha. Our results, in combination with mutagenesis and other data, suggests a model for the DNA binding of HMG boxes in which the N-terminal residues and part of helix 1 contact the minor groove on the outside of a bent DNA duplex.

    2014-01-01

    A minor structural change to tertiary sulfonamide RORc ligands led to distinct mechanisms of action. Co-crystal structures of two compounds revealed mechanistically consistent protein conformational changes. Optimized phenylsulfonamides were identified as RORc agonists while benzylsulfonamides exhibited potent inverse agonist activity. Compounds behaving as agonists in our biochemical assay also gave rise to an increased production of IL-17 in human PBMCs whereas inverse agonists led to significant suppression of IL-17 under the same assay conditions. The most potent inverse agonist compound showed >180-fold selectivity over the ROR isoforms as well as all other nuclear receptors that were profiled. PMID:25815138

    ABSTRACT To understand the geographical distribution of lettuce drop incidence and the structure of Sclerotinia minor and S. sclerotiorum populations, commercial lettuce fields were surveyed in the Salinas, San Joaquin, and Santa Maria Valleys in California. Lettuce drop incidence, pathogen species, and mycelial compatibility groups (MCGs) were determined and analyzed using geostatistic and geographical information system tools. Lettuce drop incidence was lowest in the San Joaquin Valley, and not significantly different between the other two valleys. Semivariogram analysis revealed that lettuce drop incidence was not spatially correlated between different fields in the Salinas Valley, suggesting negligible field-to-field spread or influence of inoculum in one field on other fields. Lettuce drop incidence was significantly lower in fields with a surface drip system than in fields with furrow or sprinkler irrigation systems, suggesting that the surface drip system can be a potential management measure for reducing lettuce drop. In the San Joaquin Valley, S. sclerotiorum was the prevalent species, causing drop in 63.5% of the fields, whereas S. minor also was identified in 25.4% of the fields. In contrast, in the Salinas Valley, S. minor was the dominant species (76.1%) whereas S sclerotiorum only observed in only 13.6% fields, in which only a few plants were infected by S. sclerotiorum. In the Santa Maria Valley, both species frequently were identified, with S. minor being slightly more common. Although many MCGs were identified in S. minor, most of them consisted of only one or two isolates. In all, approximately 91.4% of the isolates belonged to four MCGs. Among them, MCG-1 was the most prevalent group in all three valleys, accounting for 49.8% of total isolates. It was distributed all over the surveyed areas, whereas other MCGs were distributed more or less locally. Populations of S. sclerotiorum exhibited greater diversity, with 89 isolates collected from the

    Factors responsible for spatial structuring of population genetic variation are varied, and in many instances there may be no obvious explanations for genetic structuring observed, or those invoked may reflect spurious correlations. A study of little penguins (Eudyptula minor) in southeast Australia documented low spatial structuring of genetic variation with the exception of colonies at the western limit of sampling, and this distinction was attributed to an intervening oceanographic feature (Bonney Upwelling), differences in breeding phenology, or sea level change. Here, we conducted sampling across the entire Australian range, employing additional markers (12 microsatellites and mitochondrial DNA, 697 individuals, 17 colonies). The zone of elevated genetic structuring previously observed actually represents the eastern half of a genetic cline, within which structuring exists over much shorter spatial scales than elsewhere. Colonies separated by as little as 27 km in the zone are genetically distinguishable, while outside the zone, homogeneity cannot be rejected at scales of up to 1400 km. Given a lack of additional physical or environmental barriers to gene flow, the zone of elevated genetic structuring may reflect secondary contact of lineages (with or without selection against interbreeding), or recent colonization and expansion from this region. This study highlights the importance of sampling scale to reveal the cause of genetic structuring. PMID:25833231

    Many viruses regulate translation of polycistronic mRNA using a -1 ribosomal frameshift induced by an RNA pseudoknot. A pseudoknot has two stems that form a quasi-continuous helix and two connecting loops. A 1.6 A crystal structure of the beet western yellow virus (BWYV) pseudoknot reveals rotation and a bend at the junction of the two stems. A loop base is inserted in the major groove of one stem with quadruple-base interactions. The second loop forms a new minor-groove triplex motif with the other stem, involving 2'-OH and triple-base interactions, as well as sodium ion coordination. Overall, the number of hydrogen bonds stabilizing the tertiary interactions exceeds the number involved in Watson-Crick base pairs. This structure will aid mechanistic analyses of ribosomal frameshifting.

    Pseudomonas aeruginosa utilizes the type II secretion machinery to transport virulence factors through the outer membrane into the extracellular space. Five proteins in the type II secretion system share sequence homology with pilin subunits of type IV pili and are called the pseudopilins. The major pseudopilin X{sub cp}T{sub G} assembles into an intraperiplasmic pilus and is thought to act in a piston-like manner to push substrates through an outer membrane secretin. The other four minor pseudopilins, X{sub cp}U{sub H}, X{sub cp}V{sub I}, X{sub cp}W{sub J} and X{sub cp}X{sub K}, play less well defined roles in pseudopilus formation. It was recently discovered that these four minor pseudopilins form a quaternary complex that is presumed to initiate the formation of the pseudopilus and to localize to its tip. Here, the structure of X{sub cp}W{sub J} was refined to 1.85 {angstrom} resolution. The structure revealed the type IVa pilin fold with an embellished variable antiparallel {beta}-sheet as also found in the X{sub cp}W{sub J} homologue enterotoxigenic Escherichia coli G{sub sp}J{sub W} and the X{sub cp}U{sub H} homologue Vibrio cholerae E{sub ps}U{sub H}. It is proposed that the exposed surface of this sheet may cradle the long N-terminal 1 helix of another pseudopilin. The final 31 amino acids of the X{sub cp}W{sub J} structure are instrinsically disordered. Deletion of this unstructured region of X{sub cp}W{sub J} did not prevent type II secretion in vivo.

    Two structural proteins form the capsids of papillomaviruses. The major structural protein L1 is the structural determinant of the capsids and is present in 360 copies arranged in 72 pentamers. The minor structural protein L2 is estimated to be present in twelve copies per capsid. Possible roles for L2 in interaction with cell surface receptors and in virion uptake have been suggested. As previously reported, L2 localizes in subnuclear domains identified as nuclear domain 10 (ND10). As it was demonstrated that L2 is able to recruit viral and cellular proteins to ND10, a possible role for L2 as a mediator in viral assembly has been proposed. In this study, we determined factors influencing the localization of L2 at ND10. Under conditions of moderate L2 expression level and in the absence of heterologous viral components, we observed that, in contrast to previous reports, L2 is mainly distributed homogeneously throughout the nucleus. L2, however, is recruited to ND10 at a higher expression level or in the presence of viral components derived from vaccinia virus or from Semliki Forest virus. We observed that translocation of L2 to ND10 is not a concentration-dependent accumulation but rather seems to be triggered by yet unidentified cellular factors. In contrast to HPV 11 and 16 L2, the HPV 18 L2 protein seems to require L1 for efficient nuclear accumulation.

    The authors investigated theoretically core-hole effects on X-ray absorption near-edge structures (XANES) of Np and Am LIII in neptunium dioxide (NpO2) and americium dioxide (AmO2) with CaF2-type crystal lattices using the all-electron full-potential linearized augmented plane-wave (FP-LAPW) method. The peak creation mechanism of XANES was shown by examining the electronic structures of these oxides, which indicated that core-hole screening was more marked for AmO2 than for NpO2 because of the difference in the charge transfer between these oxides. Furthermore, the results of charge density analysis suggested that the white line was assigned to the quasi-bound state composed of the localized Np d or Am d components and O components, and that the tail structure was created as a result of delocalized standing waves between the Np or Am atoms.

    Venus upper atmosphere (70-150 km altitude) is a transition region characterized by a complex dynamics: strong retrograde zonal winds dominate the lower mesosphere while a solar-to-antisolar circulation is observed in the upper mesosphere/lower thermosphere. In addition, photochemical processes play an important role at these altitudes and affect the thermal structure and chemical stability of the entire atmosphere. Sulfur dioxide and water vapor are key species in the photochemical cycles taking place in the troposphere and mesosphere of Venus. They are carried by convective transport, together with the Hadley circulation, up to about 60 km where SO2 is photodissociated and oxydated, leading to the formation of H2SO4 which condenses in the clouds enshrouding the planet. Previous observations obtained by several instruments on board Venus Express and during ground-based campaigns have shown evidence of strong temporal variations, both on day-to-day as well as longer timescales, of density, temperature and SO2 abundance. Such strong variability is still not well understood.Submillimeter observations obtained with the Atacama Large Millimeter Array (ALMA) offer the possibility of probing Venus upper mesosphere and of monitoring minor species, winds and the thermal structure. A first set of observations was obtained on November 14, 15, 26 and 27, 2011 during the first ALMA Early Science observation cycle. These observations targeted SO2, SO, HDO and CO transitions around 345 GHz during four sequences of 30 minutes each. The Venus’ disk was about 11” with an illumination factor of 90%, so that mostly the dayside of the planet was mapped.Assuming nominal night-time and dayside CO abundance profiles from Clancy et al. 2013, we retrieved vertical temperature profiles over the entire disk as a function of latitude and local time for the four days of observation. Temperature profiles were later used to derive the abundances of minor species (HDO, SO, SO2) in each pixel

    The role of microhydration in structural adjustments of the AT-tract in B-DNA was studied at the B97-D/def2-SV(P) level. The (dA:dT)5 complexes with 10 water molecules in minor and 15 water molecules in major grooves were studied. The obtained network of hydrogen bonds revealed the dependence between the groove width and the types of water patterns. In the minor groove, the following patterns were observed: interstrand one-water bridges similar to that of the Dickerson "water spine" and interstrand two-water bridges. The network of structural waters in the major groove is more diverse than that in the minor groove, which agrees with crystallographic data. As the major groove is wider, it is enriched by water molecules forming two- and three-water bridges. Results suggest the nucleobase-water interactions in both grooves prevent AT-tract twisting and its "collapse" along the minor groove. Whereby, a helix structure with narrow minor and wide major grooves is formed. The structural waters affect the polynucleotide conformation so that it becomes similar to poly(dA)·poly(dT) in fibers and acquires features of the A-tracts in DNA in solution. We suggest that formation of specific water patterns in both grooves is the factor responsible for stabilization of A-tracts with a narrowed minor groove, leading in turn to their strong intrinsic bending in DNA.

    The origin of meridional reflections in the X-ray diffraction patterns of vertebrate skeletal muscles in resting and rigor states was studied. The main results may be summarized as follows. 1. Most of the meridional reflections localized in groups at the positions of successive orders of the repeat period of about 430 A are contributed mainly by the C-protein component of thick filaments. 2. The meridional reflections at about 143 and 72 A in the X-ray diffraction pattern of the resting muscle are contributed mainly by the cross-bridge axial repeat period, while in the X-ray diffraction patterns of the rigorized muscle the reflections at approximately the same positions are contributed mainly by C-protein. The change in the positions of these particular reflections accompanying the transition of the muscle from rest to rigor and from rest to contraction cannot be considered as an indication of a change in the axial repeat period of the cross-bridges, as it was earlier suggested by some authors. 3. The transition of the muscle from resting to rigor state is accompanied by substantial changes in the positions of the meridional reflections contributed my minor proteins, which is indicative of the structural transition in the thick filaments. The observed changes may be interpreted as the result of the thick filaments elongation by about 1.5% or, alternatively, as a consequence of the redistribution of electron density of the meridional reflections 215 and 143 A during a single twitch of the muscle (Huxley et al., Nature, 1980 284, 140) may be interpreted as a natural consequence of the structural change in the thick filaments. It is concluded therefore that on stimulation of the vertebrate skeletal muscle the thickness filaments undergo a reversible structural change which may reflect the existence of myosin-linked regulation in that type of muscle.

    Degradation of rebaudioside M, a minor sweet component of Stevia rebaudiana Bertoni, under conditions that simulated extreme pH and temperature conditions has been studied. Thus, rebaudioside M was treated with 0.1 M phosphoric acid solution (pH 2.0) and 80 °C temperature for 24 h. Experimental results indicated that rebaudioside M under low pH and higher temperature yielded three minor degradation compounds, whose structural characterization was performed on the basis of 1D (1H-, 13C-) & 2D (COSY, HSQC, HMBC) NMR, HRMS, MS/MS spectral data as well as enzymatic and acid hydrolysis studies.

    Background and Aims Ulmus minor has been severely affected by Dutch elm disease (DED). The introduction into Europe of the exotic Ulmus pumila, highly tolerant to DED, has resulted in it widely replacing native U. minor populations. Morphological and genetic evidence of hybridization has been reported, and thus there is a need for assessment of interspecific gene flow patterns in natural populations. This work therefore aimed at studying pollen gene flow in a remnant U. minor stand surrounded by trees of both species scattered across an agricultural landscape. Methods All trees from a small natural stand (350 in number) and the surrounding agricultural area within a 5-km radius (89) were genotyped at six microsatellite loci. Trees were morphologically characterized as U. minor, U. pumila or intermediate phenotypes, and morphological identification was compared with Bayesian clustering of genotypes. For paternity analysis, seeds were collected in two consecutive years from 20 and 28 mother trees. Maximum likelihood paternity assignment was used to elucidate intra- and interspecific gene flow patterns. Key Results Genetic structure analyses indicated the presence of two genetic clusters only partially matching the morphological identification. The paternity analysis results were consistent between the two consecutive years of sampling and showed high pollen immigration rates (∼0·80) and mean pollination distances (∼3 km), and a skewed distribution of reproductive success. Few intercluster pollinations and putative hybrid individuals were found. Conclusions Pollen gene flow is not impeded in the fragmented agricultural landscape investigated. High pollen immigration and extensive pollen dispersal distances are probably counteracting the potential loss of genetic variation caused by isolation. Some evidence was also found that U. minor and U. pumila can hybridize when in sympatry. Although hybridization might have beneficial effects on both species, remnant U

    The minor cerebrosides from a Far-Eastern glass sponge Aulosaccus sp. were analyzed as constituents of some multi-component RP-HPLC fractions. The structures of eighteen new and one known cerebrosides were elucidated on the basis of NMR spectroscopy, mass spectrometry, optical rotation data and chemical transformations. These β-D-glucopyranosyl-(1→1)-ceramides contain sphingoid bases N-acylated with straight-chain (2R)-2-hydroxy fatty acids, namely, (2S,3S,4R,11Z)-2-aminoeicos-11-ene-1,3,4-triol, acylated with 15E-22:1, 16Z-21:1, 15Z-21:1, 15Z-20:1, 15E-20:1, 19:0, 18:0 acids, (2S,3S,4R)-2-amino-13-methyltetradecane-1,3,4-triol--with 19Z-26:1, 16Z-23:1, 23:0, 22:0 acids, (2S,3S,4R)-2-amino-14-methylpentadecane-1,3,4-triol--with 16Z-23:1, 16E-23:1, 15Z-22:1, 22:0 acids, (2S,3S,4R)-2-amino-14-methylhexadecane-1,3,4-triol, linked to 16Z-23:1, 15Z-22:1 acids, (2S,3S,4R)-2-amino-9-methylhexadecane-1,3,4-triol--to 16Z-23:1 acid, and (2S,3S,4R)-2-aminohexadecane-1,3,4-triol, attached to 15Z-22:1 acid. The 13-methyl and 9-methyl-branched trihydroxy sphingoid base backbones (C15 and C17, respectively) have not been found previously in sphingolipids. The ceramide parts, containing other backbones, present new variants of N-acylation of the marine sphingoid bases with the 2-hydroxy fatty acids. The combination of the instrumental and chemical methods used in this study improved the efficiency of the structural analysis of such complex cerebroside mixtures that gave more detailed information on glycosphingolipid metabolism of the organism.

    Submillimeter observations obtained with the Atacama Large Millimeter Array (ALMA) allowed to monitoring the temporal evolution of temperature, sulfur species and water in the upper atmosphere of Venus. We observed the upper atmosphere of Venus with ALMA on November 14, 15, 26 and 27, 2011 during the first ALMA Early Science observation cycle. These observations targeted CO, SO, HDO and SO2 transitions around 345 GHz during four sequences of 30 minutes each. The disk of Venus was about 11" with an illumination factor of 90%, so that mostly the dayside of the planet was mapped.Thanks to the imaging capabilities of ALMA, we could obtain instantaneous maps of temperature, SO and HDO for the four days of observations. Assuming a nominal dayside CO abundance profile adapted from Clancy et al. 2012, we retrieved vertical temperature profiles between 60-100 km of altitude over the entire disk as a function of latitude and local time for the four days of observation. Temperature profiles were later used to derive the abundances of minor species (SO and HDO) in each pixel of the disk in order to study their spatial and temporal variability. Moreover, we plan to analyze the SO2 disk-averaged spectra to study its temporal variability.Temperature profiles show at all latitudes and local times a similar behavior with a constant decrease of temperature up to an altitude of about 80-100 km, depending on the local time, followed by a constant increase of temperature. Up to about 90 km temperatures increase from the morning side towards the evening terminator, this trend is inverted above 90 km. The thermal structure does not show strong temporal variations from one day to another. An exception is the thermal structure of the November 27: compared to the first day of observation, temperatures change of more than 15 K.SO exhibits a strong spatial and temporal variability with a mixing ratio ranging from 0 to 15 ppb. It presents also a clear cutoff around 89 km. HDO is detected

    BK polyomavirus is the causative agent of several diseases in transplant patients and the immunosuppressed. In order to better understand the structure and life cycle of BK, we produced infectious virions and VP1-only virus-like particles in cell culture, and determined their three-dimensional structures using cryo-electron microscopy (EM) and single-particle image processing. The resulting 7.6-Å resolution structure of BK and 9.1-Å resolution of the virus-like particles are the highest-resolution cryo-EM structures of any polyomavirus. These structures confirm that the architecture of the major structural protein components of these human polyomaviruses are similar to previous structures from other hosts, but give new insight into the location and role of the enigmatic minor structural proteins, VP2 and VP3. We also observe two shells of electron density, which we attribute to a structurally ordered part of the viral genome, and discrete contacts between this density and both VP1 and the minor capsid proteins.

    We report the enhancement of the minority carrier lifetime of GaInP with a lateral composition modulated (LCM) structure grown using molecular beam epitaxy (MBE). The structural and optical properties of the grown samples are studied by transmission electron microscopy and photoluminescence, which reveal the formation of vertically aligned bright and dark slabs corresponding to Ga-rich and In-rich GaInP regions, respectively, with good crystal quality. With the decrease of V/III ratio during LCM GaInP growth, it is seen that the band gap of LCM GaInP is reduced, while the PL intensity remains high and is comparable to that of bulk GaInP. We also investigate the minority carrier lifetime of LCM structures made with different flux ratios. It is found that the minority carrier lifetime of LCM GaInP is ∼37 times larger than that of bulk GaInP material, due to the spatial separation of electrons and holes by In-rich and Ga-rich regions of the LCM GaInP, respectively. We further demonstrate that the minority carrier lifetime of the grown LCM GaInP structures can easily be tuned by simply adjusting the V/III flux ratio during MBE growth, providing a simple yet powerful technique to tailor the electrical and optical properties at will. The exceptionally high carrier lifetime and the reduced band gap of LCM GaInP make them a highly attractive candidate for forming the top cell of multi-junction solar cells and can enhance their efficiency, and also make them suitable for other optoelectronics devices, such as photodetectors, where longer carrier lifetime is beneficial.

    The three-dimensional structure of a ternary complex of the purine repressor, PurR, bound to both its corepressor, hypoxanthine, and the 16-base pair purF operator site has been solved at 2.7 A resolution by x-ray crystallography. The bipartite structure of PurR consists of an amino-terminal DNA-binding domain and a larger carboxyl-terminal corepressor binding and dimerization domain that is similar to that of the bacterial periplasmic binding proteins. The DNA-binding domain contains a helix-turn-helix motif that makes base-specific contacts in the major groove of the DNA. Base contacts are also made by residues of symmetry-related alpha helices, the "hinge" helices, which bind deeply in the minor groove. Critical to hinge helix-minor groove binding is the intercalation of the side chains of Leu54 and its symmetry-related mate, Leu54', into the central CpG-base pair step. These residues thereby act as "leucine levers" to pry open the minor groove and kink the purF operator by 45 degrees.

  17. Structural and Dynamic Characterization of Polymerase κ’s Minor Groove Lesion Processing Reveals How Adduct Topology Impacts Fidelity

    2015-01-01

    DNA lesion bypass polymerases process different lesions with varying fidelities, but the structural, dynamic, and mechanistic origins of this phenomenon remain poorly understood. Human DNA polymerase κ (Polκ), a member of the Y family of lesion bypass polymerases, is specialized to bypass bulky DNA minor groove lesions in a predominantly error-free manner, by housing them in its unique gap. We have investigated the role of the unique Polκ gap and N-clasp structural features in the fidelity of minor groove lesion processing with extensive molecular modeling and molecular dynamics simulations to pinpoint their functioning in lesion bypass. Here we consider the N2-dG covalent adduct derived from the carcinogenic aromatic amine, 2-acetylaminofluorene (dG-N2-AAF), that is produced via the combustion of kerosene and diesel fuel. Our simulations reveal how the spacious gap directionally accommodates the lesion aromatic ring system as it transits through the stages of incorporation of the predominant correct partner dCTP opposite the damaged guanine, with preservation of local active site organization for nucleotidyl transfer. Furthermore, flexibility in Polκ’s N-clasp facilitates the significant misincorporation of dTTP opposite dG-N2-AAF via wobble pairing. Notably, we show that N-clasp flexibility depends on lesion topology, being markedly reduced in the case of the benzo[a]pyrene-derived major adduct to N2-dG, whose bypass by Polκ is nearly error-free. Thus, our studies reveal how Polκ’s unique structural and dynamic properties can regulate its bypass fidelity of polycyclic aromatic lesions and how the fidelity is impacted by lesion structures.

    Young children's executive function (EF) is increasingly recognized as an important construct associated with development in cognitive and socioemotional domains. To date, however, few studies have examined EF in populations of language-minority children. In this study, 241 Spanish-speaking language-minority preschoolers who ranged in age from 38 to 69 months (M=54.23 months, SD=6.17) completed three tasks designed to measure inhibitory control (IC) and four tasks designed to measure working memory (WM). Children completed assessments of their vocabulary skills, early literacy skills, and behavioral self-regulation in both English and Spanish, and their classroom teachers completed three behavior rating measures. Children were classified as more proficient in English or Spanish based on their scores on the vocabulary measures, and all IC and WM measures were administered in the children's more proficient language. Results of confirmatory factor analyses supported a two-factor model of EF for both groups of children as well as strong measurement and structural invariance across groups. Children's EF was substantially related to the language, early literacy, and behavioral self-regulation measures as well as teacher ratings of inattention and hyperactivity/impulsivity. For children with more proficient English, EF was associated with skills in both English and Spanish; however, for children with more proficient Spanish, EF was associated primarily with skills in Spanish. These results provide evidence of strong correspondence for EF measured in Spanish-speaking language-minority preschoolers and monolingual preschoolers, and they identify a potential key factor that can enhance understanding of development in this population of children.

    Mcl-1 is an antiapoptotic Bcl-2-family protein that protects cells against death. Structures of Mcl-1, and of other anti-apoptotic Bcl-2 proteins, reveal a surface groove into which the {alpha}-helical BH3 regions of certain proapoptotic proteins can bind. Despite high overall structural conservation, differences in this groove afford binding specificity that is important for the mechanism of Bcl-2 family function. We report the crystal structure of human Mcl-1 bound to a BH3 peptide derived from human Bim and the structures for three complexes that accommodate large physicochemical changes at conserved Bim sites. The mutations had surprisingly modest effects on complex stability, and the structures show that Mcl-1 can undergo small changes to accommodate the mutant ligands. For example, a shift in a leucine side chain fills a hole left by an isoleucine-to-alanine mutation at the first hydrophobic buried position of Bim BH3. Larger changes are also observed, with shifting of helix {alpha}3 accommodating an isoleucine-to-tyrosine mutation at this same position. We surveyed the variation in available Mcl-1 and Bcl-x{sub L} structures and observed moderate flexibility that is likely critical for facilitating interactions of diverse BH3-only proteins with Mcl-1. With the antiapoptotic Bcl-2 family members attracting significant attention as therapeutic targets, these structures contribute to our growing understanding of how specificity is achieved and can help to guide the design of novel inhibitors that target Mcl-1.

    1994-09-01

    In this paper, the structures for electricity demand in non-Latino Black and White households are compared. Electricity demand will be analyzed within the context of a complete demand system, and statistical tests for structural differences will be systematically conducted in the hope of pinpointing the location of differences within the context of this model. Structural differences in demand are defined as statistically significant differences in a parameter or group of parameters that identify the quantitative relationship between explanatory variables and electricity consumption. Along with population taste differences, which might emanate from historical and cultural population differences, structural differences might also occur because of differences in housing and geographic patterns and as a result of differences in access to markets and information. As a consequence, energy consumption decisions will differ, and the level and composition of energy consumption are likely to vary. In practice, it is nearly impossible to untangle the causes contributing to structural differences, but it is reasonably easy to test for statistical differences. The superficial evidence indicates there is a strong likelihood that structural differences do exist in electricity demand between White and Black households. The null hypothesis, which states that there exist no differences in the structures for electricity demand for Black and White households, is tested.

    Two proteins, HifD and HifE, have been identified as structural components of Haemophilus influenzae pili. Both are localized at the pilus tip, and HifE appears to mediate pilus adherence to host cells. In this study we examined the immunologic and structural diversity of these pilus subunits among type b H. influenzae (Hib) and nontypeable H. influenzae (NTHI) strains. Western immunoblot analysis revealed that antibodies directed against the C terminus of HifD and HifE from Hib strain Eagan bound to HifD and HifE proteins, respectively, of all piliated Hib and NTHI strains tested. Whole-cell enzyme-linked immunosorbent assays showed that antibodies specific for native HifD or HifE of strain Eagan also bound to all piliated Hib strains but did not bind to the piliated NTHI strains. Antibodies against HifE of strain Eagan inhibited the binding of Hib to human erythrocytes but did not inhibit the binding of NTHI strains. Restriction fragment length polymorphism (RFLP) analysis was used to determine strain-to-strain structural differences within hifD and hifE genes, either by PCR or by nucleotide sequence analysis. DNA and derived amino acid sequence analyses of HifD and HifE confirmed the uniqueness of the RFLP types. The hifD and hifE genes of all type b strains showed identical restriction patterns. Analysis of hifD and hifE genes from the NTHI strains, however, revealed seven unique RFLP patterns, suggesting that these genes encode proteins with diverse primary structures. These results indicate that HifD and HifE are immunologically and structurally similar among the Hib strains but vary among the NTHI strains. PMID:9746580

    Many Gram-negative bacteria use the multi-protein type II secretion system (T2SS) to selectively translocate virulence factors from the periplasmic space into the extracellular environment. In Vibrio cholerae the T2SS is called the extracellular protein secretion (Eps) system, which translocates cholera toxin and several enzymes in their folded state across the outer membrane. Five proteins of the T2SS, the pseudopilins, are thought to assemble into a pseudopilus, which may control the outer membrane pore EpsD, and participate in the active export of proteins in a 'piston-like' manner. We report here the 2.0 {angstrom} resolution crystal structure of an N-terminally truncated variant of EpsH, a minor pseudopilin from Vibrio cholerae. While EpsH maintains an N-terminal {alpha}-helix and C-terminal {beta}-sheet consistent with the type 4a pilin fold, structural comparisons reveal major differences between the minor pseudopilin EpsH and the major pseudopilin GspG from Klebsiella oxytoca: EpsH contains a large {beta}-sheet in the variable domain, where GspG contains an {alpha}-helix. Most importantly, EpsH contains at its surface a hydrophobic crevice between its variable and conserved {beta}-sheets, wherein a majority of the conserved residues within the EpsH family are clustered. In a tentative model of a T2SS pseudopilus with EpsH at its tip, the conserved crevice faces away from the helix axis. This conserved surface region may be critical for interacting with other proteins from the T2SS machinery.

    An investigation of the strong-acid characteristics (pKa 3.0 or less) of fulvic acid from the Suwannee River, Georgia, was conducted. Quantitative determinations were made for amino acid and sulfur-containing acid structures, oxalate half-ester structures, malonic acid structures, keto acid structures, and aromatic carboxyl-group structures. These determinations were made by using a variety of spectrometric (13C-nuclear magnetic resonance, infrared, and ultraviolet spectrometry) and titrimetric characterizations on fulvic acid or fulvic acid samples that were chemically derivatized to indicate certain functional groups. Only keto acid and aromatic carboxyl-group structures contributed significantly to the strong-acid characteristics of the fulvic acid; these structures accounted for 43% of the strong-acid acidity. The remaining 57% of the strong acids are aliphatic carboxyl groups in unusual and/or complex configurations for which limited model compound data are available.

    Synthetic routes to alkyl and aryl substituted dithiophosphinate salts that contain non-coordinating PPh{sub 4}{sup 1+} counter cations are reported. In general, these compounds can be prepared via a multi-step procedure that starts with reacting secondary phosphines, i.e. HPR{sub 2}, with two equivalents elemental S. This transformation proceeds in two steps - first oxidation of the phosphine and second insertion of S into the H-P bond - and has been used to synthesize a series of dithiophoshinic acids, which were fully characterized, namely HS{sub 2}P(p-CF{sub 3}C{sub 6}H{sub 4}){sub 2}, HS{sub 2}P(m-CF{sub 3}C{sub 6}H{sub 4}){sub 2}, HS{sub 2}P(o-MeC{sub 6}H{sub 4}){sub 2}, and HS{sub 2}P(o-MeOC{sub 6}H{sub 4}){sub 2}. Although the insertion step was found to be much slower than the oxidation reaction, the formation of (NH{sub 4})S{sub 2}PR{sub 2} from HPSR{sub 2} occurs almost instantaneous upon addition of NH{sub 4}OH. Subsequent cation exchange reactions proceed readily with PPh{sub 4}Cl in water, under air, and at ambient conditions to provide analytically pure samples of [PPh{sub 4}][S{sub 2}PR{sub 2}] (R = p-CF{sub 3}C{sub 6}H{sub 4}, m-CF{sub 3}C{sub 6}H{sub 4}, o-CF{sub 3}C{sub 6}H{sub 4}, o-MeC{sub 6}H{sub 4}, o-MeOC{sub 6}H{sub 4}, Ph, and Me, 1b-7b, respectively), which were characterized by elemental analysis, multinuclear NMR, and IR spectroscopy. In addition the S{sub 2}PMe{sub 2}{sup 1-}, S{sub 2}PPh{sub 2}{sup 1-}, and dithiophosphinates with ortho-substituted arene rings were characterized by X-ray crystallography. Structural analysis show that, as opposed to the acids which have short P=S double bonds and long P-SH single bonds, the metric parameters for the S atoms in S{sub 2}PR{sub 2}{sup 1-} are equivalent. In addition, the presence of large non-coordinating PPh{sub 4}{sup 1+} cations guard against intermolecular P-S {hor_ellipsis} X interactions and insure that the P-S bond is isolated.

    Spider silk is protein fibers with extraordinary mechanical properties. Up to now, it is still poorly understood how silk proteins are kept in a soluble form before spinning into fibers and how the protein molecules are aligned orderly to form fibers. Minor ampullate spidroin is one of the seven types of silk proteins, which consists of four types of domains: N-terminal domain, C-terminal domain (CTD), repetitive domain (RP) and linker domain (LK). Here we report the tertiary structure of CTD and secondary structures of RP and LK in aqueous solution, and their roles in protein stability, solubility and fiber formation. The stability and solubility of individual domains are dramatically different and can be explained by their distinct structures. For the tri-domain miniature fibroin, RP-LK-CTDMi, the three domains have no or weak interactions with one another at low protein concentrations (<1 mg/ml). The CTD in RP-LK-CTDMi is very stable and soluble, but it cannot stabilize the entire protein against chemical and thermal denaturation while it can keep the entire tri-domain in a highly water-soluble state. In the presence of shear force, protein aggregation is greatly accelerated and the aggregation rate is determined by the stability of folded domains and solubility of the disordered domains. Only the tri-domain RP-LK-CTDMi could form silk-like fibers, indicating that all three domains play distinct roles in fiber formation: LK as a nucleation site for assembly of protein molecules, RP for assistance of the assembly and CTD for regulating alignment of the assembled molecules.

    Synchrotron X-ray micro-diffraction experiments were carried out on Nephila clavipes (NC) and Argiope aurantia (AA) major (MA) and minor ampullate (MiA) fibers that make up dragline spider silk. The diffraction patterns show a semi-crystalline structure with {beta}-poly(L-alanine) nanocrystallites embedded in a partially oriented amorphous matrix. A superlattice reflection 'S' diffraction ring is observed, which corresponds to a crystalline component larger in size and is poorly oriented, when compared to the {beta}-poly(L-alanine) nanocrystallites that are commonly observed in dragline spider silks. Crystallite size, crystallinity and orientation about the fiber axis have been determined from the wide-angle X-ray diffraction (WAXD) patterns. In both NC and AA, the MiA silks are found to be more highly crystalline, when compared with the corresponding MA silks. Detailed analysis on the amorphous matrix shows considerable differences in the degree of order of the oriented amorphous component between the different silks studied and may play a crucial role in determining the mechanical properties of the silks.

  11. Major Variations in HIV-1 Capsid Assembly Morphologies Involve Minor Variations in Molecular Structures of Structurally Ordered Protein Segments.

    2016-06-17

    We present the results of solid state nuclear magnetic resonance (NMR) experiments on HIV-1 capsid protein (CA) assemblies with three different morphologies, namely wild-type CA (WT-CA) tubes with 35-60 nm diameters, planar sheets formed by the Arg(18)-Leu mutant (R18L-CA), and R18L-CA spheres with 20-100 nm diameters. The experiments are intended to elucidate molecular structural variations that underlie these variations in CA assembly morphology. We find that multidimensional solid state NMR spectra of (15)N,(13)C-labeled CA assemblies are remarkably similar for the three morphologies, with only small differences in (15)N and (13)C chemical shifts, no significant differences in NMR line widths, and few differences in the number of detectable NMR cross-peaks. Thus, the pronounced differences in morphology do not involve major differences in the conformations and identities of structurally ordered protein segments. Instead, morphological variations are attributable to variations in conformational distributions within disordered segments, which do not contribute to the solid state NMR spectra. Variations in solid state NMR signals from certain amino acid side chains are also observed, suggesting differences in the intermolecular dimerization interface between curved and planar CA lattices, as well as possible differences in intramolecular helix-helix packing.

    In gram-negative bacteria, the assembly of type IV pilus (T4P) and the evolutionally related pseudopilus of type II secretion system involves specialized structural proteins called pilins and pseudopilins, respectively, and is dynamically regulated to promote bacterial pathogenesis. Previous studies have suggested that a structural "tip"-like hetero-complex formed through the interaction of at least three minor (pseudo) pilins plays an important role in this process, while some members of the pathogenic type IVb subfamily are known to have only one such minor pilin subunit whose function is still unknown. Here, we determined the crystal structure of the type IVb minor pilin CofB of colonization factor antigen/III from human enterotoxigenic Escherichia coli at 1.88-Å resolution. The crystal structure, in conjunction with physicochemical analysis in solution, reveals a symmetrical homo-trimeric arrangement distinct from the hetero-complexes of minor (pseudo) pilins observed in other T4P and type II secretion systems. Each CofB monomer adopts a unique three-domain architecture, in which the C-terminal β-sheet-rich lectin domain can effectively initiate trimer association of its pilin-like N-terminal domain through extensive hydrophobic interactions followed by domain swapping at the central hinge-like domain. Deletion of cofB produces a phenotype with no detectable pili formation on the cell surface, while molecular modeling indicates that the characteristic homo-trimeric structure of CofB is well situated at the pilus tip of colonization factor antigen/III formed by the major pilin CofA, suggesting a role for the minor pilin in the efficient initiation of T4P assembly.

    With the increasing number and variations of genome sequences available control of gene expression with synthetic, cell permeable molecules is within reach. The variety of sequence-specific-binding agents is, however, still quite limited. Many minor groove binding agents selectivity recognize AT over GC sequences but have less ability to distinguish among different AT sequences. The goal with this paper is to develop compounds that can bind selectively to different AT sequences. A number of studies indicate that AATT and TTAA sequences have significantly different physical and interaction properties and different requirements for minor groove recognition. Although it has been difficult to get minor groove binding at TTAA, DB293, a phenyl-furan-benzimidazole-diamidine, was found to bind as a strong, cooperative dimer at TTAA but with no selectivity over AATT. In order to improve selectivity, modifications were made to each unit of DB293. Binding affinities and stoichiometries obtained from biosensor-surface plasmon resonance experiments show that DB1003, a furan-furan-benzimidazole diamidine binds strongly to TTAA as a dimer and has selectivity (KTTAA/KAATT = 6). CD and DNAse I footprinting studies confirmed the preference of this compound for TTAA. In summary (i) a favorable stacking surface provided by the pi system, (ii) H-bond donors to interact with TA base pairs at the floor of the groove provided by a benzimidazole (or indole) –NH and amidines, and (iii) appropriate curvature of the dimer complex to match the curvature of the minor groove play important roles in differentiating the TTAA and AATT minor grooves.

    Type IV pili are extracellular polymers of the major pilin subunit. These subunits are held together in the pilus filament by hydrophobic interactions among their N-terminal α-helices, which also anchor the pilin subunits in the inner membrane prior to pilus assembly. Type IV pilus assembly involves a conserved group of proteins that span the envelope of Gram-negative bacteria. Among these is a set of minor pilins, so named because they share their hydrophobic N-terminal polymerization/membrane anchor segment with the major pilins but are much less abundant. Minor pilins influence pilus assembly and retraction, but their precise functions are not well defined. The Type IV pilus systems of enterotoxigenic Escherichia coli and Vibrio cholerae are among the simplest of Type IV pilus systems and possess only a single minor pilin. Here we show that the enterotoxigenic E. coli minor pilins CofB and LngB are required for assembly of their respective Type IV pili, CFA/III and Longus. Low levels of the minor pilins are optimal for pilus assembly, and CofB can be detected in the pilus fraction. We solved the 2.0 Å crystal structure of N-terminally truncated CofB, revealing a pilin-like protein with an extended C-terminal region composed of two discrete domains connected by flexible linkers. The C-terminal region is required for CofB to initiate pilus assembly. We propose a model for CofB-initiated pilus assembly with implications for understanding filament growth in more complex Type IV pilus systems as well as the related Type II secretion system.

  20. Fine structure of E. coli RNA polymerase-promoter interactions: α subunit binding to the UP element minor groove

    Ross, Wilma; Ernst, Alexander; Gourse, Richard L.

    2001-01-01

    The α subunit of E. coli RNAP plays an important role in the recognition of many promoters by binding to the A+T-rich UP element, a DNA sequence located upstream of the recognition elements for the ς subunit, the −35 and −10 hexamers. We examined DNA–RNAP interactions using high resolution interference and protection footprinting methods and using the minor groove-binding drug distamycin. Our results suggest that α interacts with bases in the DNA minor groove and with the DNA backbone along the minor groove, but that UP element major groove surfaces do not make a significant contribution to α binding. On the basis of these and previous results, we propose a model in which α contacts UP element DNA through amino acid residues located in a pair of helix–hairpin–helix motifs. Furthermore, our experiments extend existing information about recognition of the core promoter by ς70 by identifying functional groups in the major grooves of the −35 and −10 hexamers in which modifications interfere with RNAP binding. These studies greatly improve the resolution of our picture of the promoter–RNAP interaction. PMID:11238372

    We developed the first Vietnamese Internalized Homophobia (IH) scale for use with Vietnamese sexual minority women (SMW). Drawing from existing IH scales in the international literature and based on prior qualitative research about SMW in the Viet Nam context, the scale covers two domains: self-stigma (negative attitudes toward oneself as a sexual minority person) and sexual prejudice (negative attitudes toward homosexuality/same-sex relations in general). Scale items, including items borrowed from existing scales and items based on local expressions, were reviewed and confirmed by members of the target population. Quantitative evaluation used data from an anonymous web-based survey of Vietnamese SMW, including those who identified as lesbian (n = 1187), or as bisexual (n = 641) and those who were unsure about their sexual identity (n = 353). The scale was found to consist of two highly correlated factors reflecting self-stigma (not normal/wholesome and self-reproach and wishing away same-sex sexuality) and one factor reflecting sexual prejudice, and to have excellent internal consistency. Construct validity was evidenced by subscale associations with a wide range of hypothesized correlates, including perceived sexual stigma, outness, social support, connection to other SMW, relationship quality, psychological well-being, anticipation of heterosexual marriage, and endorsement of same-sex marriage legalization. Self-stigma was more strongly associated with psychosocial correlates, and sexual prejudice was more associated with endorsement of legal same-sex marriage. The variations in these associations across the hypothesized correlates and across sexual identity groups were consistent with the minority stress model and the IH literature, and exhibited context-specific features, which are discussed.

    Ce1-xEuxPO4 (x = 0-1) solid solutions were synthesized by the solid state reaction process using europium (Eu) as the surrogate for trivalent minor actinide americium (Am). The effects of calcination temperature, holding time and Eu content on the crystalline phase, microstructure and morphology of Ce1-xEuxPO4 (x = 0-1) were investigated. The monazite-type EuPO4 and CePO4 coexisted after being calcined at 1000 °C for 4 h, suggesting the CePO4 and EuPO4 phases would form initially separately. Pure and single-phase monazite-type Ce1-xEuxPO4 (x = 0-1) powders were obtained at 1300 °C for 4 h. The results of the XRD patterns Rietveld refinement and μ-Raman analysis confirmed the formation of a Ce1-xEuxPO4 (x = 0-1) continuous solid solution. The grain size of Ce0.5Eu0.5PO4 increased obviously as the holding time extended. The Ce, Eu, P and O elements were almost distributed homogeneously in the Ce0.5Eu0.5PO4 solid solution.

    Field elm (Ulmus minor) is a riparian tree that grows in rare, small populations scattered along temporary watercourses in the Balearic Islands, nowadays mostly covered with Mediterranean vegetation. Agriculture and farming on the fertile land along the periodically flooded plains have reduced the elm populations to sparse tree lines along the creek beds. The presence of field elm in this very anthropic landscape has led some authors to consider it as an introduced species in the Balearics. However, pollen data suggest these elms may be the remains of larger populations experiencing continuous population shrinkage during the Holocene, and hence be native to the isles. In this paper, we apply genetic markers to assess whether field elm is or is not indigenous to the Balearic Islands. We compare the genetic variation in nine nuclear microsatellites of six Balearic populations (three in each of the largest islands, Majorca and Minorca) with that of three natural Iberian populations located in two regions, one geologically (Baetic mountains, SE Iberia) and another historically (Catalonia, NE Iberia) related to the islands. Principal coordinates analysis and Bayesian clustering methods reveal a strong genetic differentiation of the Balearic populations from the Iberian ones, and even among islands, which support their native origin. Genotypic variation in the islands is very low and clonal reproduction is very high compared with the mainland, as it is frequently observed in populations of clonal species where sexual reproduction is limited. We discuss the practical implications of these findings for the conservation of elm genetic resources of these findings.

    Video meteor observations provide us with data to analyze structures in minor meteor showers or weak features in flux profiles. Samples obtained independently by other techniques allow to calibrate the data sets and to improve the confidence of results as demonstrated with a few results. Both, the confirmation of events predicted by model calculation and the input of observational data to improve the modelling results may help to better understand meteoroid stream evolution processes. Furthermore, calibrated data series can be used for studies of the long-term evolution of meteor shower activity.

    This study examined how parenting factors were associated with adolescent problem behaviors among urban minority youth and to what extent these relationships were moderated by family structure and gender. Sixth-grade students (N = 228) reported how often they use alcohol, smoke cigarettes, or engage in aggressive or delinquent behaviors; a parent or guardian reported their monitoring and other parenting practices. Findings indicated that boys and those from single-parent families engaged in the highest rates of problem behavior. More parental monitoring was associated with less delinquency overall, as well as less drinking in boys only. Eating family dinners together was associated with less aggression overall, as well as less delinquency in youth from single-parent families and in girls. Unsupervised time at home alone was associated with more smoking for girls only. Implications for prevention interventions are discussed.

    The recent confirmation of the discovery of a satellite of the minor planet 532 Herculina indicates that other similar anomalous sightings are probably also due to satellites, which must therefore be numerous and commonplace. There are now 23 candidate satellites for eight minor planets, and no one of these minor planets occulting a star has failed to show evidence of at least one secondary event. Such companions are gravitationally stable but apparently have rapid tidal evolution rates.

  11. Photosynthetic acclimation: structural reorganisation of light harvesting antenna--role of redox-dependent phosphorylation of major and minor chlorophyll a/b binding proteins.

    2008-03-01

    In order to carry out photosynthesis, plants and algae rely on the co-operative interaction of two photosystems: photosystem I and photosystem II. For maximum efficiency, each photosystem should absorb the same amount of light. To achieve this, plants and green algae have a mobile pool of chlorophyll a/b-binding proteins that can switch between being light-harvesting antenna for photosystem I or photosystem II, in order to maintain an optimal excitation balance. This switch, termed state transitions, involves the reversible phosphorylation of the mobile chlorophyll a/b-binding proteins, which is regulated by the redox state of the plastoquinone-mediating electron transfer between photosystem I and photosystem II. In this review, we will present the data supporting the function of redox-dependent phosphorylation of the major and minor chlorophyll a/b-binding proteins by the specific thylakoid-bound kinases (Stt7, STN7, TAKs) providing a molecular switch for the structural remodelling of the light-harvesting complexes during state transitions. We will also overview the latest X-ray crystallographic and electron microscopy-derived models for structural re-arrangement of the light-harvesting antenna during State 1-to-State 2 transition, in which the minor chlorophyll a/b-binding protein, CP29, and the mobile light-harvesting complex II trimer detach from the light-harvesting complex II-photosystem II supercomplex and associate with the photosystem I core in the vicinity of the PsaH/L/O/P domain.

    Large-scale transitions in societies are associated with both individual behavioural change and restructuring of the social network. These two factors have often been considered independently, yet recent advances in social network research challenge this view. Here we show that common features of societal marginalization and clustering emerge naturally during transitions in a co-evolutionary adaptive network model. This is achieved by explicitly considering the interplay between individual interaction and a dynamic network structure in behavioural selection. We exemplify this mechanism by simulating how smoking behaviour and the network structure get reconfigured by changing social norms. Our results are consistent with empirical findings: The prevalence of smoking was reduced, remaining smokers were preferentially connected among each other and formed increasingly marginalized clusters. We propose that self-amplifying feedbacks between individual behaviour and dynamic restructuring of the network are main drivers of the transition. This generative mechanism for co-evolution of individual behaviour and social network structure may apply to a wide range of examples beyond smoking. PMID:27510641

    We earlier identified a developmental series of seven isoforms/polymorphs of microparticulate inulin by comparing non-covalent bonding strengths. Their pharmaceutical utility lies in modulation of cellular immunity, exploited as vaccine adjuvants (Advax™) especially for delta inulin (DI). As such particles cannot be sterilized by filtration we explore the effect of 60Co gamma radiation (GR) on inulin isoforms, particularly DI. Its adjuvant activity and overt physical properties were unaffected by normal GR sterilizing doses (up to 25 kGy). Heating irradiated isoform suspensions near their critical dissolution temperature revealed increased solubility deduced to reflect a single lethal event in one component of a multi-component structure. Local oxidative effects of GR on DI were not found. The observed DI loss was almost halved by re-annealing at the critical temperature: surviving inulin chains apparently reassemble into smaller amounts of the original type of structure. Colorimetric tetrazolium assay revealed increases in reducing activity after GR of raw inulin powder, which yielded DI with normal physical properties but only 25% normal recovery yet 4× normal reducing ability, implying final retention of some GR-changed inulin chains. These findings suggest minimal inulin chain cleavage and confirm that GR may be a viable strategy for terminal sterilization of microparticulate inulin adjuvants. PMID:24342245

  20. deducing the sequence of deformations during chain building from the analysis of minor structures: the case of the Sicily Belt (Central Mediterranean)

    the structural evolution of the Sicily chain using overprinting mesoscopic fabrics and their relationships to larger structures. The geometric differences existing between some types of structures within the belt and their overprinting relationships allow delineating the timing of deformations during chain building and post-collision tectonic history. The overall structural setting of the mountain chain reflects therefore the deformation and the progressive thrusting migration forelandwards, with extensional faulting overprinting and inverting formed thrusts. Most of the data available for this work come from detailed analysis in a few key areas, ranging along the Northern Sicily, where minor structures are overprinted to form a single sequence. Our study of outcrops throughout the region has recognised that the progression of deformation is represented by four regionally-significant structural stages (layer-parallel shortening, folding-and-thrusting, extension and renewed thrusting). The first stage of deformation includes several sub-stages (layer-parallel shortening, bed-parallel simple shear and fold nucleation). Deformation continued in a second stage, where thrusting was coupled by fold amplification and tightening. Kinematic evolution is provided by a third stage, where dominantly negative inversion of previous weakened zones and mechanical discontinuities occurred, coupled by normal faults activation. Out-of-sequence thrusting follows the chain thinning phase, as the late orogenic deformation phase of the contractional tectonics which affected Sicily. Each stage is defined as a discrete phase of deformation, characterised by the development of a characteristic set of structures, such as cleavage, folds, faults and veins. Each deformative step may be sequentially framed in a kinematic history, where a continuous shortening process, halted by an extension episode due to chain overthickening, in a tectonic setting dominated by collisional tectonics.

  1. The minor structural difference between the antioxidants quercetin and 4'O-methylquercetin has a major impact on their selective thiol toxicity.

    Antioxidants act as intermediates by picking up the high unselective reactivity of radicals and transferring it to other molecules. In this process the reactivity is reduced and becomes selective. This channeling of the reactivity can cause selective toxicity. The antioxidant quercetin is known to channel the reactivity towards thiol groups. The present study compares the thiol reactivity of quercetin with that of 4'O-methylquercetin (tamarixetin) towards creatine kinase (CK), a vital protein that contains a critical thiol moiety. Our results showed that oxidized quercetin and oxidized tamarixetin both adduct CK, which then loses its enzymatic function. Ascorbate, an important representative of the antioxidant network, is able to prevent adduction to and thus the inhibition of the enzyme by tamarixetin but not by quercetin. Apparently, tamarixetin is less thiol toxic than quercetin, because--rather than adduction to CK--tamarixetin quinone prefers to pass reactivity to the antioxidant network, i.e., to ascorbate. The findings exemplify that radical scavenging flavonoids pick up the reactivity of radicals and act as a pivot in directing the way the reactivity is channeled. A mere minor structural difference of only one methyl moiety between quercetin and tamarixetin appears to have a high impact on the selective, thiol toxicity. PMID:24786288

    Praseodymium was used as the surrogate for trivalent minor actinide neptunium, and a complete series of pure monazite-type Ce1-xPrxPO4 (x = 0-1) solid solutions were successfully prepared by the solid state reaction. The effects of calcining temperature, holding time and Pr content on the structure of Ce1-xPrxPO4 solid solutions were investigated. The results show that although Pr6O11 (Pr23+Pr44+O11) exists two stabilized oxidation states, there has been no tetravalent praseodymium phosphate during the synthesis process. The optimized temperature for the synthesis of Ce0.8Pr0.2PO4 solid solution is more than 1100 °C, and a hypothetical reaction mechanism is also proposed. Besides, the crystalline grains coarsen as the increasing of holding time. The linear variation of unit cell parameters and a gradual hypsochromic shift in the Raman spectra are observed with the increase of Pr content, indicating that cerium is progressively replaced by praseodymium and Ce1-xPrxPO4 solid solutions were prepared.

  3. Right-angle pattern of minor fluvial networks from the Ionian terraced belt, southern Italy: passive structural control or foreland bending?

    whole study area, suggesting a control by a pervasive orthogonal fracture system rather than by isolated faults and/or master joints. Such a structural pattern and the arrangement of the terraces slope don't match very well with the tectonic features associated to a vertical uplift motion. Fractures were produced and preserved into the brittle caprock of the terraces, made by conglomerate, and exerted their control on the minor fluvial channels that progressively deepened into the underlying Pleistocene clay and sand, but they are not much represented in these soft rocks. Since a similar pervasive and orthogonal fracture pattern is actually generated by gentle folding of rocks, the development of the Ionian hydrographic networks could be attributed to a general - maybe still active - bending of the foredeep area due to the eastward propagation of blind thrusting of the Apennines chain.

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

    Seifertite SiO₂ likely exists as a minor phase near the core–mantle boundary. By simulating the pressure and temperature conditions near the core–mantle boundary, seifertite was synthesized as a minor phase in a coarse-grained, polycrystalline sample coexisting with the (Mg,Fe)SiO₃ post-perovskite (pPv) phase at 129 GPa and 2500 K. Here we report the first in situ single-crystal structure determination and refinement of seifertite at high pressure and after a temperature quench from laser heating. We improved the data coverage of a minor phase from a diamond-anvil cell (DAC) by merging single-crystal data of seifertite from six selected grains that had different orientations. Observed systematic absences of reflections from the six individual grains allowed only one space group: Pbcn. The refined results of seifertite are in good agreement with the predictions from previous first-principles calculations at high pressure. This approach provides a method for structure determination of a minor phase in a mineral assemblage synthesized under P-T conditions representative of the deep Earth.

    Several crystal structure analyses of complexes of synthetic polyamine compounds, including N {sup 1}-(2-(2-aminoethylamino))ethyl)ethane-1,2-diamine PA(222) and N {sup 1}-(2-(2-(2-aminoethylamino)ethylamino)ethyl)ethane-1,2-diamine PA(2222), and left-handed Z-DNA d(CGCGCG){sub 2} have been reported. However, until now, there have been no examples of naturally occurring polyamines bound to the minor groove of the left-handed Z-DNA of d(CGCGCG){sub 2} molecule. We have found that spermidine, a natural polyamine, is connected to the minor groove of left-handed Z-DNA of d(CGCGCG){sub 2} molecule in a crystalline complex grown at 10 {sup o}C. The electron density of the DNA molecule was clear enough to determine that the spermidine was connected in the minor groove of two symmetry related molecules of left-handed Z-DNA d(CGCGCG){sub 2}. This is the first example that a spermidine molecule can form a bridge conformation between two symmetry related molecules of left-handed Z-DNA d(CGCGCG){sub 2} in the minor groove.

    SUMMARY Understanding the mental health needs of lesbian and bisexual (sexual minority) women is an integral part of designing and providing appropriate mental health services and treatment for them. In an effort to understand the mental health needs of sexual minority women who seek community treatment, a chart review was conducted of the 223 lesbian and bisexual women who presented for services between July 1, 1997 and December 31, 2000 at Fenway Community Health in Boston, MA. Data are based on clients' self-reports and clinician assessments of clients' presenting problem, relevant developmental history, prior mental health and substance abuse treatment, current reports of emotional/psychological symptoms, and areas of impaired functioning. Although substance abuse and suicidal ideation were commonly reported problems, other concerns were more frequently reported. High percentages of lesbians and bisexual women reported relationship concerns and lack of adequate social networks; rates of depression and anxiety based on clinicians' assessments were also high. Overall, lesbians and bisexual women did not differ in the issues they brought to treatment or level or types of impairment. Compared with previous community survey samples, however, study participants appeared to be healthier than general, non-clinical samples of self-identified lesbians, possibly reflecting the special characteristics of sexual minority women who seek treatment in specialized community sites such as the Fenway. Although patients who come to these sites may not represent the more general population of sexual minority women, community health centers known to serve lesbian, gay, bisexual and transgender (LGBT) individuals may be fruitful access points for studying the mental health status and treatment needs of sexual minority women.

    The purpose of this research is to project household energy consumption, energy expenditure, and energy expenditure as share of income for five population groups from 1991 to 2009. The approach uses the Minority Energy Assessment Model (MEAM), developed by Argonne National Laboratory for the US Department of Energy's Office of Minority Economic Impact. The MEAM provides a framework that can be used to forecast regional energy consumption and energy expenditure for majority, black, Hispanic, poor, and nonpoor households. The forecasts of key macroeconomic and energy variables used as exogenous variables in the MEAM were obtained from the Data Resources, Inc., Macromodel and Energy Model. Generally, the projections of household energy consumption, expenditure, and energy expenditure as share of income vary across population groups and census regions.

    So far, the development of highly active and stable carbon-based electrocatalysts for oxygen reduction reaction (ORR) to replace commercial Pt/C catalyst is a hot topic. In this study, a new nanoporous nitrogen-doped carbon material was facilely designed by two-step pyrolysis of the renewable Lemna minor enriched in crude protein under a nitrogen atmosphere. Electrochemical measurements show that the onset potential for ORR on this carbon material is around 0.93 V (versus reversible hydrogen electrode), slightly lower than that on the Pt/C catalyst, but its cycling stability is higher compared to the Pt/C catalyst in an alkaline medium. Besides, the ORR at this catalyst approaches to a four-electron transfer pathway. The obtained ORR performance can be basically attributed to the formation of high contents of pyridinic and graphitic nitrogen atoms inside this catalyst. Thus, this work opens up the path in the ORR catalysis for the design of nitrogen-doped carbon materials utilizing aquatic plants as starting precursors.

The assessment of mental disability in minors is unique in that it involves developmental aspects, which affect the formation and outcome of the disability. The relationship between disability and development is reciprocal: disability can affect development, thereby intensifying the degree of disability, while development affects integration of the disability into the personality and self-image, thereby preventing or reducing the transformation of disability into handicap. Only an understanding of both the psychopathological structure and its interaction with developmental elements can lead to an accurate assessment of the degree of disability. Such an understanding is vital to the proper practice of forensic psychiatry. We hereby propose a new formula for disability quantification which provides an arithmetical means for the calculation of disability percentages in minors, and we recommend its use in the assessment of demands for National Insurance benefits and compensation claims. The relationship between this new formula and the existing Children's Global Assessment Scale (CGAS) functional scale, when tested retrospectively on 50 clinical reports composed by the writers of this article, showed a good correlation in the results obtained independently by each writer. Two case studies are presented here. A further evaluation by objective evaluators is necessary in order to construct a model for a final objective evaluation of disability in children and adolescents. PMID:16929808

  7. [Sexual abuse of minors].

    The author gives a definition of sexual abuse on minors, emphasizing its more frequent occurrence inside the family (incest) than outside. He describes the countertransference reactions induced by this type of abuse, especially in professional teams who tend to put each other in a position of rivalry. Next, he sketches the pathogeny of sexual abuse, the clinical signs and the long term effects. The author deduces what should be the first signs of sexual abuse and proposes a pattern of diagnosis. Finally, he explains a management model, of the crisis and the follow-up of this difficult situation. PMID:1670411

    Novel cyano- and 2-imidazolinyl-substituted derivatives of pyridylbenzo[b]thiophene-2-carboxamides 4, 5, 10-13 and benzo[b]thieno[2,3-c]naphthyridin-2-ones 6, 7, 14-17 were prepared. All derivatives showed a prominent antiproliferative effect. Extensive DNA binding studies and additional biological evaluations point to various modes/targets of action. The results strongly support intercalation into DNA as a dominant binding mode of fused analogues, which was substantiated using topoisomerase I inhibition assay. Most intriguingly, only minor structural difference between "nonfused" compounds 12 and 13 has strong impact on the interactions with DNA; while 13 binds within the DNA minor groove in the form of dimer, 12 does not form significant interactions with DNA. The assumption that severe mitotic impairment (G2/M phase arrest) induced by 12 could point to tubulin, another important target, was confirmed by its obvious anti-tubulin activity observed in immunofluorescence assay, whereby treated cells showed disruption of microtubule formation comparable to the effect obtained by paclitaxel, a well-known tubulin antagonist chemotherapeutic.

    Findings from previous studies corroborate the hypothesis that universalism and conservation values are associated with negative attitudes toward immigration. In the current study we examine whether universalism and conservation values also play a critical role in the explanation of attitudes toward other minority groups. Drawing on previous research on group-focused enmity, we explore its relations with universalism and conservation values in a German sample. Employing structural equation modeling, we find that individuals who prioritize universalism values approve of various minorities more whereas those who prioritize conservation values exhibit more disapproval.

    2009-01-01

    Introduction Superficial burns that affect the epidermis and upper dermis only are characterised by redness of the skin that blanches on pressure, pain, and hypersensitivity. The skin blisters within hours and usually heals with minimal scarring within 2 to 3 weeks if no infection is present. Most minor burns occur in the home, with less than 5% requiring hospital treatment. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for minor thermal burns? We searched: Medline, Embase, The Cochrane Library, and other important databases up to October 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found eight systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review, we present information relating to the effectiveness and safety of the following interventions: alginate dressing; antibiotics; chlorhexidine-impregnated paraffin gauze dressing; foam dressing; hydrocolloid dressing; hydrogel dressing; paraffin gauze dressing; polyurethane film; silicone-coated nylon dressing; and silver sulfadiazine cream.

  11. BOOK REVIEW: Minority Games

    NASA Astrophysics Data System (ADS)

    2005-02-01

    New branches of scientific disciplines often have a few paradigmatic models that serve as a testing ground for theories and a starting point for new inquiries. In the late 1990s, one of these models found fertile ground in the growing field of econophysics: the Minority Game (MG), a model for speculative markets that combined conceptual simplicity with interesting emergent behaviour and challenging mathematics. The two basic ingredients were the minority mechanism (a large number of players have to choose one of two alternatives in each round, and the minority wins) and limited rationality (each player has a small set of decision rules, and chooses the more successful ones). Combining these, one observes a phase transition between a crowded and an inefficient market phase, fat-tailed price distributions at the transition, and many other nontrivial effects. Now, seven years after the first paper, three of the key players—Damien Challet, Matteo Marsili and Yi-Cheng Zhang—have published a monograph that summarizes the current state of the science. The book consists of two parts: a 100-page overview of the various aspects of the MG, and reprints of many essential papers. The first chapters of Part I give a well-written description of the motivation and the history behind the MG, and then go into the phenomenology and the mathematical treatment of the model. The authors emphasize the `physics' underlying the behaviour and give coherent, intuitive explanations that are difficult to extract from the original papers. The mathematics is outlined, but calculations are not carried out in great detail (maybe they could have been included in an appendix). Chapter 4 then discusses how and why the MG is a model for speculative markets, how it can be modified to give a closer fit to observed market statistics (in particular, reproducing the `stylized facts' of fat-tailed distributions and volatility clustering), and what conclusions one can draw from the behaviour of the MG

  12. NMR solution structure of an N2-guanine DNA adduct derived from the potent tumorigen dibenzo[a,l]pyrene: Intercalation from the minor groove with ruptured Watson-Crick base pairing

    The most potent tumorigen identified among the polycyclic aromatic hydrocarbons (PAH) is the non-planar fjord region dibenzo[a,l]pyrene (DB[a,l]P). It is metabolically activated in vivo through the widely-studied diol epoxide (DE) pathway to form covalent adducts with DNA bases, predominantly guanine and adenine. The (+)-11S,12R,13R,14S DE enantiomer forms adducts via its C14-position with the exocyclic amino group of guanine. Here, we present the first NMR solution structure of a DB[a,l]P-derived adduct, the 14R (+)-trans-anti-DB[a,l]P–N2-dG (DB[a,l]P-dG) lesion in double-stranded DNA. In contrast to the stereochemically identical benzo[a]pyrene-derived N2-dG adduct (B[a]P-dG) in which the B[a]P rings reside in the B-DNA minor groove on the 3’-side of the modifed deoxyguanosine, in the DB[a,l]P-derived adduct the DB[a,l]P rings intercalate into the duplex on the 3’-side of the modified base from the sterically crowded minor groove. Watson-Crick base pairing of the modified guanine with the partner cytosine is broken, but these bases retain some stacking with the bulky DB[a,l]P ring system. This new theme in PAH DE - DNA adduct conformation differs from: (1) the classical intercalation motif where Watson-Crick base-pairing is intact at the lesion site, and (2) the base-displaced intercalation motif in which the damaged base and its partner are extruded from the helix . The structural considerations that lead to the intercalated conformation of the DB[a,l]P-dG lesion in contrast to the minor groove alignment of the B[a]P-dG adduct, and the implications of the DB[a,l]P-dG conformational motif for the recognition of such DNA lesions by the human nucleotide excision repair apparatus, are discussed.

    We investigated the effects of lifelong voluntary exercise on articular cartilage of mice. At the age of 4 weeks C57BL mice (n = 152) were divided into two groups, with one group serving as a sedentary control whereas the other was allowed free access to a running wheel from the age of 1 month onward. Mice were euthanized at four different time points (1, 2, 6, and 18 months of age). Articular cartilage samples were gathered from the load-bearing area of the tibial medial plateaus, and osteoarthritis was graded. Additionally, the proteoglycan content distribution was assessed using digital densitometry, collagen fibril orientation, and parallelism with polarized light microscopy, and collagen content using Fourier transform infrared imaging spectroscopy. The incidence of osteoarthritis increased with aging, but exercise had no effect on this trend. Furthermore, the structure and composition revealed significant growth, maturation, and age-dependent properties. Exercise exerted a minor effect on collagen fibril orientation in the superficial zone. Fibril orientation at 2 months of age was more perpendicular to surface (p < 0.05) in controls compared with runners, whereas the situation was reversed at the age of 18 months (p < 0.05). The collagen content of the superficial zone was higher (p < 0.01) at the age of 18 months in controls compared with runners but the proteoglycan content did not display any exercise-dependent changes. In conclusion, growth, maturation, and aging exerted a clear effect on integrity, structure, and composition of medial tibial plateau articular cartilage in mice, whereas lifelong voluntary exercise had only a minor effect on collagen architecture and content.

    The purpose is to investigate and demonstrate equipment and techniques proposed for minor surgery on Space Station Freedom (SSF). The objectives are: (1) to test and evaluate methods of surgical instrument packaging and deployment; (2) to test and evaluate methods of surgical site preparation and draping; (3) to evaluate techniques of sterile procedure and maintaining sterile field; (4) to evaluate methods of trash management during medical/surgical procedures; and (4) to gain experience in techniques for performing surgery in microgravity. A KC-135 parabolic flight test was performed on March 30, 1990 with the goal of investigating and demonstrating surgical equipment and techniques under consideration for use on SSF. The flight followed the standard 40 parabola profile with 20 to 25 seconds of near-zero gravity in each parabola.

    M13 bacteriophage has been used as a scaffold to organize materials for various applications. Building more complex multi-phage devices requires precise control of interactions between the M13 capsid proteins. Towards this end, we engineered a loop structure onto the pIII capsid protein of M13 bacteriophage to enable sortase-mediated labeling reactions for C-terminal display. Combining this with N-terminal sortase-mediated labeling, we thus created a phage scaffold that can be labeled orthogonally on three capsid proteins: the body and both ends. We show that covalent attachment of different DNA oligonucleotides at the ends of the new phage structure enables formation of multi-phage particles oriented in a specific order. These have potential as nanoscale scaffolds for multi–material devices. PMID:23713956

    The structures of the (R)- and (S)-alpha-(N2-guanyl)styrene oxide adducts at X6 in d(GGCAGXTGGTG).d(CACCACCTGCC), encompassing codon 12 of the human n-ras protooncogene (underlined), were refined from 1H NMR data. These were the R(12,2) and S(12,2) adducts. For the R(12,2) adduct, upfield chemical shifts were observed for the T7 H6, H1', and N3H resonances. At 30 degrees C, R-SOG 6 N1H, T7 N3H, and T10 N3H disappeared due to exchange with solvent. For the S(12,2) adduct, S-SOG6 H1' shifted upfield 0.33 ppm, but all imino resonances were observed. The styrene methylene protons were nonequivalent for both adducts, suggesting hydrogen bonding between the hydroxyl and C18 O2 or O4' in the R(12,2) adduct and C17 O2 in the S(12,2) adduct. The styrene aromatic protons appeared as three signals in the R(12,2) adduct and as two signals in the S(12,2) adduct, suggesting rapid rotation of the styrene ring on the NMR time scale. NOE data revealed that the phenyl ring was oriented in the 3'-direction relative to R-SOG6 for the R(12,2) adduct and in the 5'-direction relative to S-SOG6 for the S(12,2) adduct. A total of 253 and 221 interproton distances were obtained from relaxation matrix analyses of the R(12,2) and S(12,2) adducts, respectively. NOE-restrained molecular dynamics calculations converged with root mean square deviations of 0.8-1.2 A for the R(12,2) adduct and 0.82-1.4 A for the S(12,2) adduct. Complete relaxation matrix analyses of the nine inner base pairs yielded sixth root residual indices between calculated and experimental NOE intensities of 8.8 x 10(-2) for the R(12,2) adduct and 7.9 x 10(-2) for the S(12,2) adduct. The refined structure for the R(12,2) adduct showed a 0.4 A increase in the stretch of R-SOG6.C17 and T7.A16, and a 1-2 A widening of the minor groove at and adjacent to the SO lesion, with the styrene ring oriented edgewise in the minor groove. Smaller minor groove disturbances were observed for the S(12,2) adduct, which had the styrene ring

    1986-01-01

    The parentals of the interspecific cross Cucurbita maxima x C. ecuadorensis had different isozyme phenotypes for 12 enzyme systems. Characterization of the systems demonstrated that the expression and intracellular distribution of the isozymes were similar to those in other plant taxa; however, a considerable number of duplicate loci were identified, indicative of a polyploid ancestry for Cucurbita. Genetic analysis provided evidence for 20 loci segregating in F2 and backcross populations. Five linkage groups were identified, consisting of the loci Aat-mb – – Mdh-m2; Gal-1 – – Gal-2; Aat-p2 – – Gpi-c2; Acp-1 – – Pgm-c2 – – Pgm-p; and Est-1 – – Tpi-c2. Significant deviations from Mendelian segregation ratios were observed in 14% of the data sets for individual loci. However, these instances were scattered among the loci, no single locus consistently displaying skewed ratios. Recombination frequencies between linked loci were similar to those observed in intraspecific crosses, and the ratio of heterozygous to homozygous genotypes in backcross populations was very close to one. These results suggest that small differences in chromosome structure were not the major cause of the loss of fertility observed in F2 and backcross populations. PMID:17246350

    SimR, a TetR-family transcriptional regulator (TFR), controls the export of simocyclinone, a potent DNA gyrase inhibitor made by Streptomyces antibioticus. Simocyclinone is exported by a specific efflux pump, SimX and the transcription of simX is repressed by SimR, which binds to two operators in the simR-simX intergenic region. The DNA-binding domain of SimR has a classical helix-turn-helix motif, but it also carries an arginine-rich N-terminal extension. Previous structural studies showed that the N-terminal extension is disordered in the absence of DNA. Here, we show that the N-terminal extension is sensitive to protease cleavage, but becomes protease resistant upon binding DNA. We demonstrate by deletion analysis that the extension contributes to DNA binding, and describe the crystal structure of SimR bound to its operator sequence, revealing that the N-terminal extension binds in the minor groove. In addition, SimR makes a number of sequence-specific contacts to the major groove via its helix-turn-helix motif. Bioinformatic analysis shows that an N-terminal extension rich in positively charged residues is a feature of the majority of TFRs. Comparison of the SimR–DNA and SimR–simocyclinone complexes reveals that the conformational changes associated with ligand-mediated derepression result primarily from rigid-body rotation of the subunits about the dimer interface.

Conference speakers spoke of the social and economic changes that are needed if minorities are to participate in the economics of the technological age. These include better educational opportunities and cooperation between civil rights groups and energy planners. Other topics were venture opportunities for minorities in energy-related fields and opportunities for minority advocacy and energy efficiency actions.

    2015-02-01

    Previous research indicates that lesbian, gay, and bisexual (LGB) adolescents are at increased risk for substance use, including heightened rates of marijuana use. Minority stress theory suggests that difficult social situations create a state of chronic stress that leads to poor health outcomes for LGB adults; however, the applicability of this model has not been well explored in relation to substance use among LGB adolescents. The current study is a secondary analysis of the OutProud survey, conducted in 2000. The original study used purposive sampling to collect data from 1,911 LGB adolescents (age 12-17) across the United States, and represents the largest known study to explore experiences specific to identifying as LGB, such as homophobia and gay-related victimization. We used structural equation modeling (SEM) to explore the feasibility of applying a minority stress framework to understand marijuana use in this population. The final structural model for marijuana use in the LGB adolescent sample displayed excellent fit and modest explanatory power for marijuana use. Two of the five factors, community connectedness and internalized homophobia, were significantly (p < .05) associated with marijuana use. Findings suggest that minority stress theory may be appropriately applied to marijuana use in this population; however, better measurement of minority stress concepts for LGB adolescents is needed.

  17. Minority workers or minority human beings? A European dilemma

    1996-07-01

    "European" identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as "European", and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

  18. Minors and Sexting: Legal Implications.

    Sexting is the sending or forwarding of sexually explicit photographs or videos of the sender or someone known to the sender via cell phone. It has become common practice among young people, as cell phones are being given to adolescents at ever younger ages. Youths often send messages without giving appropriate thought to the content of the images. In studies on the subject, rates of minors who have sent sexual images range from 4 to 25 percent, depending on the age of the youths surveyed, the content of the messages and other factors. Because transferring and viewing sexually explicit material when the subject is a minor can be considered child pornography, there can be serious legal consequences. Several states have enacted legislation to help differentiate between child pornography and sexting by minors. The trend reflected in statutes has been that minors involved in sexting without other exacerbating circumstances should be charged with a less serious offense. There is no clear national consensus on how sexting by minors is adjudicated, and therefore we compared several statutes. Case examples are used to illustrate the range of legal outcomes, from felony charges to no charges. Two sexting episodes that were followed by suicide are described. We also address the role of the forensic mental health professional. PMID:26944746

  2. Fast clique minor generation in Chimera qubit connectivity graphs

    Boothby, Tomas; King, Andrew D.; Roy, Aidan

    2016-01-01

    The current generation of D-Wave quantum annealing processor is designed to minimize the energy of an Ising spin configuration whose pairwise interactions lie on the edges of a Chimera graph C_{M,N,L}. In order to solve an Ising spin problem with arbitrary pairwise interaction structure, the corresponding graph must be minor-embedded into a Chimera graph. We define a combinatorial class of native clique minors in Chimera graphs with vertex images of uniform, near minimal size and provide a polynomial-time algorithm that finds a maximum native clique minor in a given induced subgraph of a Chimera graph. These minors allow improvement over recent work and have immediate practical applications in the field of quantum annealing.

  3. Office management of minor wounds.

    OBJECTIVE: To review office interventions for minor wounds not requiring sutures, such as abrasions, bites, and lacerations. QUALITY OF EVIDENCE: Most information on minor wound management comes from descriptive studies. Few comparative studies examine the effectiveness of topical antisepsis for minor wounds. Several clinical trials have demonstrated that tissue adhesives produce short- and long-term cosmetic results equivalent to those achieved with suture materials. MAIN MESSAGE: Sterile saline is the least toxic solution for wound irrigation. Chlorhexidine (2%) and povidone iodine (10%) have been the most investigated antiseptic solutions. Systemic antibiotics are unnecessary for wounds unlikely to be infected. All bite wounds require special attention. Primary closure of bite wounds is indicated in certain circumstances: less than 12-hour-old nonpuncture wounds, uninfected wounds, and low-risk lesions (such as on the face). In spite of their many advantages, skin tapes should be used for low-tension wounds only. The popularity of tissue adhesives has greatly increased. Since the advent of newer products (with increased bonding strength and flexibility), adhesives are used to manage most lacerations except those in areas of high tension (e.g., joints) and on mucosal surfaces. CONCLUSION: Minor wounds not requiring sutures can be managed easily in the office. PMID:11340758

  14. Isolation and characterization of a minor fimbria from Porphyromonas gingivalis.

    PubMed Central

    Hamada, N; Sojar, H T; Cho, M I; Genco, R J

    1996-01-01

    We have discovered two distinctly different fimbriae expressed by the same Porphyromonas gingivalis strain. The construction of a fimA mutant of P. gingivalis ATCC 33277 has previously been reported by N. Hamada et al. (Infect. Immun. 62:1696-1704, 1994). Expression of fimbriae on the surface of the fimA mutant and the wild-type strain, ATCC 33277, were investigated by electron microscopy. The wild-type strain produced long fimbrial structures extending from the cell surface, whereas those structures were not observed on the fimA mutant. However, short fimbrial structures were seen on the surface of the fimA mutant. The short fimbrial protein was purified from the fimA mutant by selective protein precipitation and chromatography on DEAE Sepharose CL-6B. We have found that the second fimbrial structure of P. gingivalis ATCC 33277 is distinct from the 41-kDa (43-kDa) major fimbrial protein (FimA). We provisionally call this protein minor fimbriae. The molecular mass of the minor fimbriae is 67 kDa as estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis under reducing conditions after boiling at 100 degrees C. The component shows a ladder-like pattern at 80 degrees C under nonreducing conditions, suggesting a tendency to aggregate or polymerize. In immunoblotting analysis, anti-minor fimbria serum reacted with both the 100 degrees C- and the 80 degrees C-treated minor fimbriae. The anti-minor fimbria serum also reacts with the same-molecular-size fimbrial preparation from the wild-type strain. Immunogold electron microscopy showed that the anti-minor fimbria serum bound to the minor fimbria on the cell surface of the wild-type strain. This is the first report on the identification of the minor fimbria produced by P. gingivalis. These results suggest that the minor fimbriae appearing on the fimA mutant strain are produced together with numerous long major fimbriae on the wild-type strain. Moreover, the minor fimbriae are different in size and

  15. Breast screening and ethnic minorities.

    PubMed

    Hoare, T

    1996-09-01

    The concern for minority ethnic women is whether they are disadvantaged either in terms of the incidence of breast cancer or because of a lower uptake of screening. There are considerable worldwide variations in the incidence of breast cancer. The lowest rates are found in Chinese, Japanese and Arabic populations and women from the Indian subcontinent, and are 2-3 times lower than that of the UK. This may change in future generations. Although minority ethnic women are not a high risk group for the breast screening programme, in absolute terms breast cancer is a major health problem. Very few studies have measured ethnic differences in the uptake of screening, and they may be confounded by such factors as socio-economic group. When this is accounted for, uptake by Asian women may not necessarily be lower than by other women in the same area and can be higher for black than white women. One of the most important reasons for non-attendance is inaccurate screening registers, compounded for Asian women by their return, or extended visits, to the Indian subcontinent. A further organisational issue concerns poor awareness of minority ethnic naming systems, causing confusion over the receipt of invitations. Comprehension of the concept of screening may be difficult for minority ethnic women yet there has been little evaluation of strategies to promote understanding. However a randomised controlled trial of a linkworker intervention, designed to be feasible for implementation on a population basis, showed no increase in the uptake of breast screening by Asian women. This does not undermine linkworkers' role but suggests that their efforts should be used in other ways. It is essential to assess the relative importance of reasons for low uptake and evaluate measures to meet any unmet need, so that resources can be directed in the most effective way. PMID:8782797

  16. Properties of interaction networks underlying the minority game

    NASA Astrophysics Data System (ADS)

    Caridi, Inés

    2014-11-01

    The minority game is a well-known agent-based model with no explicit interaction among its agents. However, it is known that they interact through the global magnitudes of the model and through their strategies. In this work we have attempted to formalize the implicit interactions among minority game agents as if they were links on a complex network. We have defined the link between two agents by quantifying the similarity between them. This link definition is based on the information of the instance of the game (the set of strategies assigned to each agent at the beginning) without any dynamic information on the game and brings about a static, unweighed and undirected network. We have analyzed the structure of the resulting network for different parameters, such as the number of agents (N ) and the agent's capacity to process information (m ), always taking into account games with two strategies per agent. In the region of crowd effects of the model, the resulting networks structure is a small-world network, whereas in the region where the behavior of the minority game is the same as in a game of random decisions, networks become a random network of Erdos-Renyi. The transition between these two types of networks is slow, without any peculiar feature of the network in the region of the coordination among agents. Finally, we have studied the resulting static networks for the full strategy minority game model, a maximal instance of the minority game in which all possible agents take part in the game. We have explicitly calculated the degree distribution of the full strategy minority game network and, on the basis of this analytical result, we have estimated the degree distribution of the minority game network, which is in accordance with computational results.

    2004-11-01

    The discovery of binary systems in the near-Earth, main belt, and Kuiper belt populations provides an abundance of new data that expand our knowledge of the physics and chemistry of the solar system. Binary minor planets form as a result of collisional, tidal, and capture processes that are important to study as they play major roles in the formation and evolution of planetary systems. The frequency of occurrence of such processes directly reflects the dynamical environment in the various populations. Observations of binaries provide a powerful way to measure the bulk properties of small bodies, which in turn lead to inferences about their composition and internal structure. These data may offer a rare glimpse of what physical and chemical conditions prevailed when protoplanets formed, and what subsequent evolution took place. In the case of the Kuiper Belt, the study of a handful of binaries forces us to rethink how dense and how bright these bodies are, and to significantly revise our current mass estimates for the entire population. The number of known binary minor planets has increased dramatically over the past few years, with roughly ten new discoveries each year. I will attempt to summarize recent developments, with examples drawn from my observations with the Hubble, Palomar, Keck, Arecibo and Goldstone telescopes.

  5. Strategies employed by sexual minority adolescents to cope with minority stress

    2015-01-01

    Sexual minority adolescents (SMA) experience disparities in health and behavioral health outcomes, including high rates of depression, anxiety, self-harm, substance use, HIV risk behavior, suicidal ideation, and suicide attempts. These outcomes are commonly attributed to minority stress. Stress experiences are different for SMA than their adult counterparts. For example, disclosing their sexual orientation may be more likely to result in homelessness because these youth more often live with parents or other family members. Although stress in this population has been explored in previous research, very little is known about how SMA cope. Relying upon an adolescent coping model, this study examined the coping strategies, responses, and resources of SMA related to stress. Forty-eight racially and ethnically diverse SMA (age 14–19) were recruited for 90-minute tape-recorded interviews. The semi-structured interviews were guided by a life history calendar. Recordings were transcribed verbatim and entered into QSR NVivo. All transcripts were coded by two members of the research team and went through a consensus process. Forty-three unique coping statements emerged that fit with the Compas model of adolescent coping. SMA cope with minority stress in similar ways to heterosexual youth coping with general stress, but findings suggest that SMA may also use different kinds of coping resources. Although further research is needed, the present study identified a variety of ways SMA cope with stress and can inform future research on the development interventions. PMID:26634221

  18. Minor Actinides Recycling in PWRs

    SciTech Connect

    Delpech, M.; Golfier, H.; Vasile, A.; Varaine, F.; Boucher, L.; Greneche, D.

    2006-07-01

    Recycling of minor actinides in current and near future PWR is considered as one of the options of the general waste management strategy. This paper presents the analysis of this option both from the core physics and fuel cycle point of view. A first indicator of the efficiency of different neutron spectra for transmutation purposes is the capture to fission cross sections ratio which is less favourable by a factor between 5 to 10 in PWRs compared to fast reactors. Another indicator presented is the production of high ranking isotopes like Curium, Berkelium or Californium in the thermal or epithermal spectrum conditions of PWR cores by successive neutron captures. The impact of the accumulation of this elements on the fabrication process of such PWR fuels strongly penalizes this option. The main constraint on minor actinides loadings in PWR (or fast reactors) fuels are related to their direct impact (or the impact of their transmutation products) on the reactivity coefficients, the reactivity control means and the core kinetics parameters. The main fuel cycle physical parameters like the neutron source, the alpha decay power, the gamma and neutrons dose rate and the criticality aspects are also affected. Recent neutronic calculations based on a reference core of the Evolutionary Pressurized Reactor (EPR), indicates typical maximum values of 1 % loadings. Different fuel design options for minor actinides transmutation purposes in PWRs are presented: UOX and MOX, homogeneous and heterogeneous assemblies. In this later case, Americium loading is concentrated in specific pins of a standard UOX assembly. Recycling of Neptunium in UOX and MOX fuels was also studied to improve the proliferation resistance of the fuel. The impact on the core physics and penalties on Uranium enrichment were underlined in this case. (authors)

  19. An early evolutionary origin for the minor spliceosome.

    PubMed

    Russell, Anthony G; Charette, J Michael; Spencer, David F; Gray, Michael W

    2006-10-19

    The minor spliceosome is a ribonucleoprotein complex that catalyses the removal of an atypical class of spliceosomal introns (U12-type) from eukaryotic messenger RNAs. It was first identified and characterized in animals, where it was found to contain several unique RNA constituents that share structural similarity with and seem to be functionally analogous to the small nuclear RNAs (snRNAs) contained in the major spliceosome. Subsequently, minor spliceosomal components and U12-type introns have been found in plants but not in fungi. Unlike that of the major spliceosome, which arose early in the eukaryotic lineage, the evolutionary history of the minor spliceosome is unclear because there is evidence of it in so few organisms. Here we report the identification of homologues of minor-spliceosome-specific proteins and snRNAs, and U12-type introns, in distantly related eukaryotic microbes (protists) and in a fungus (Rhizopus oryzae). Cumulatively, our results indicate that the minor spliceosome had an early origin: several of its characteristic constituents are present in representative organisms from all eukaryotic supergroups for which there is any substantial genome sequence information. In addition, our results reveal marked evolutionary conservation of functionally important sequence elements contained within U12-type introns and snRNAs.

  20. Utilization of Minor Actinides (Np, Am, Cm) in Nuclear Power Reactor

    NASA Astrophysics Data System (ADS)

    Gerasimov, A.; Bergelson, B.; Tikhomirov, G.

    2014-06-01

    Calculation research of the utilization process of minor actinides (transmutation with use of power released) is performed for specialized power reactor of the VVER type operating on the level of electric power of 1000 MW. Five subsequent cycles are considered for the reactor with fuel elements containing minor actinides along with enriched uranium. It was shown that one specialized reactor for the one cycle (900 days) can utilize minor actinides from several VVER-1000 reactors without any technological and structural modifications. Power released because of minor actinide fission is about 4% with respect to the total power

  1. Ethnic Minority-Majority Unions in Estonia.

    van Ham, Maarten; Tammaru, Tiit

    2011-08-01

    Ethnic minority-majority unions-also referred to as mixed ethnic unions-are often seen as the ultimate evidence of the integration of ethnic minorities into their host societies. We investigated minority-majority unions in Estonia, where ethnic minorities account for one-third of the total population (Russians 26%, followed by Ukrainians, Byelorussians, Finns and other smaller groups). Using data from the 2000 Estonian census and regression models, we found that Slavic women are less likely to be in minority-majority unions than are members of other minority groups, with Russians being the least likely. Finns, who are culturally most similar to the Estonian majority population, are the most likely to form a union with an Estonian. For ethnic minority women, the likelihood of being in minority-majority unions is highest in rural areas and increases over generations, with third-generation immigrants being the most likely. Estonian women are most likely to have a minority partner when they or their parents were born abroad and when they live in urban areas. Our findings suggest that both the opportunity to meet potential partners and openness to other ethnic groups are important factors for understanding the dynamics of minority-majority unions.

    PubMed

    Jaffe, M E; Sharma, K K

    2001-11-01

    This paper is designed to assist forensic psychiatrists/psychologists who evaluate adults who commit sexual crimes against children on the Internet. The typical offender is an adult male who logs onto the Internet and enters a chat room in which children congregate. Unbeknownst to the offender, undercover police officers are posing as minors in the chat rooms. The undercover officer (pretend kid) and offender engage in increasingly explicit, sexual conversation; the offender may transmit erotic photographs to the undercover officer and/or arrange to meet at a motel in order to have sexual intercourse. The authors will discuss the relevant legal, clinical, and ethical aspects of examining these offenders, and describe specific cases that the author (2) evaluated. PMID:11714151

    Wernette, D.R.; Nieves, L.A.

    1994-05-01

    Scientists at Argonne National Laboratory have been studying the relative potential for exposure of minority population groups to substandard outdoor air quality. The US Environmental Protection Agency (EPA) has identified areas that have excess levels of ozone, carbon monoxide, sulfur dioxide, nitrogen dioxide, lead, or particulate matter. These areas generally consist of counties covering many square miles, and the degree to which their residents are exposed to air pollution certainly varies. However, the differences in population groups living in these areas can imply differences in potential exposure to pollutants and may suggest directions for research and remedial action. So far, the scientists have examined these differences for African-Americans, Hispanics, and Whites (non-Hispanic).

  4. Trans-diagnostic Psychopathology Factors and Sexual Minority Mental Health: Evidence of Disparities and Associations with Minority Stressors

    PubMed Central

    Eaton, Nicholas R.

    2014-01-01

    Research on mental health disparities between sexual minority individuals and heterosexuals has traditionally taken a disorder-by-disorder approach. Recently developed trans-diagnostic approaches provide a new method to frame such investigations; however, trans-diagnostic factors have yet to be applied to sexual minority mental health disparities research. The current study applied this methodology to investigate mental health disparities between lesbian, gay, bisexual, and heterosexual individuals in a large national probability sample (N = 34,653). Twelve-month diagnoses of 13 common mood, anxiety, substance use, and personality disorders were modeled, and multi-group analysis indicated a sexual orientation-invariant trans-diagnostic latent structure. Significant disparities at the latent trans-diagnostic factor level were observed; these factor-level disparities are manifested as observed mental disorder disparities. Gender differences typically seen in trans-diagnostic research were not present between sexual minority women and men. Trans-diagnostic internalizing and externalizing factors were then used as outcomes in a minority stress framework and were positively predicted by lifetime history of sexual orientation-related minority stressors (i.e., discrimination and victimization). Implications for using trans-diagnostic approaches to frame intervention efforts, supplement disorder-by-disorder disparities methodologies, and synthesize piecemeal disparities literatures are discussed.

  5. Minor elements in Keweenawan lavas, Michigan

    USGS Publications Warehouse

    Cornwall, H.R.; Rose, H.J.

    1957-01-01

    The distribution of minor elements in three basaltic flows of the Keweenawan series, of Michigan, is related to differentiation in the flows. Thus, nickel is most abundant in the early differentiates; nickel, chromium, and barium are generally deficient in the pegmatites, which formed late; whereas copper, vanadium, yttrium, and other minor elements are concentrated in the pegmatites. The minor-element content of individual minerals in the Greenstone flow varies markedly from one mineral to another and seems to depend primarily on the presence or absence in the minerals of major elements for which the minor elements can substitute. Minor elements have substituted most readily for those major elements with similar ionic radii. Valence and electronegativity also seem to influence the ease of substitution. The distribution of other minor elements in copper-bearing lodes of the Michigan copper district shows no apparent relation to copper mineralization. ?? 1957.

    Traumatic brain injury (TBI) is the leading cause of death and disability in the young, active population and expected to be the third leading cause of death in the whole world until 2020. The disease is frequently referred to as the silent epidemic, and many authors highlight the "unmet medical need" associated with TBI.The term traumatically evoked brain injury covers a heterogeneous group ranging from mild/minor/minimal to severe/non-salvageable damages. Severe TBI has long been recognized to be a major socioeconomical health-care issue as saving young lives and sometimes entirely restituting health with a timely intervention can indeed be extremely cost efficient.Recently it has been recognized that mild or minor TBI should be considered similarly important because of the magnitude of the patient population affected. Other reasons behind this recognition are the association of mild head injury with transient cognitive disturbances as well as long-term sequelae primarily linked to repeat (sport-related) injuries.The incidence of TBI in developed countries can be as high as 2-300/100,000 inhabitants; however, if we consider the injury pyramid, it turns out that severe and moderate TBI represents only 25-30 % of all cases, while the overwhelming majority of TBI cases consists of mild head injury. On top of that, or at the base of the pyramid, are the cases that never show up at the ER - the unreported injuries.Special attention is turned to mild TBI as in recent military conflicts it is recognized as "signature injury."This chapter aims to summarize the most important features of mild and repetitive traumatic brain injury providing definitions, stratifications, and triage options while also focusing on contemporary knowledge gathered by imaging and biomarker research.Mild traumatic brain injury is an enigmatic lesion; the classification, significance, and its consequences are all far less defined and explored than in more severe forms of brain injury

  8. Micromechanics of Minor Cervical Spine Injuries

    NASA Astrophysics Data System (ADS)

    Niederer, Peter F.; Schmitt, Kai-Uwe; Muser, Markus H.; Walz, Felix H.

    Minor soft tissue injuries of the cervical spine are of increasing significance in public health. They may in particular be associated with long-term impairment. Such injuries are observed primarily in rear-end automobile collisions at low impact speeds and are attributed to a “whiplash”-type event. The question with respect to injury mechanisms of the cervical spine in cases of impacts of a low severity have raised controversial views in the past. Among proposed injury mechanisms, interactions between fluid and solid structures have been postulated: Viscous shear stresses or pressure gradients which arise in the deforming anatomical structures may have an adverse influence, e. g., on cellular membranes. In this communication, mathematical modeling approaches are presented which allow for a quantification of fluid/solid interactions under typical loading conditions of interest here. It is found, that the shear stresses caused by fluids and acting on accelerated surfaces of fluid-filled bodies depend largely on the size of the fluid space under consideration. Accelerations exhibit a stronger influence than their duration. It cannot be excluded that critical levels are reached even in a low speed impact scenario.

    1992-01-01

    This report documents the program and data used to identify known asteroids observed by the Infrared Astronomical Satellite (IRAS) and to compute albedos and diameters from their IRAS fluxes. It also presents listings of the results obtained. These results supplant those in the IRAS Asteroid and Comet Survey, 1986. The present version used new and improved asteroid orbital elements for 4679 numbered asteroids and 2632 additional asteroids for which at least two-opposition elements were available as of mid-1991. It employed asteroid absolute magnitudes on the International Astronomical Union system adopted in 1991. In addition, the code was modified to increase the reliability of associating asteroids with IRAS sources and rectify several shortcomings in the final data products released in 1986. Association reliability was improved by decreasing the position difference between an IRAS source and a predicted asteroid position required for an association. The shortcomings addressed included the problem of flux overestimation for low SNR sources and the systematic difference in albedos and diameters among the three wavelength bands (12, 25, and 60 micrometers). Several minor bugs in the original code were also corrected.

  18. Minor histocompatibility antigens: past, present, and future.

    PubMed

    Spierings, Eric

    2014-10-01

    Minor histocompatibility (H) antigens are key molecules driving allo-immune responses in both graft-versus-host-disease (GvHD) and in graft-versus-leukemia (GvL) reactivity in human leukocyte antigen (HLA)-matched hematopoietic stem-cell transplantation (HSCT). Dissection of the dual function of minor H antigens became evident through their different modes of tissue and cell expression, i.e. hematopoietic system-restricted or broad. Broadly expressed minor H antigens can cause both GvHD and GvL effects, while hematopoietic system-restricted minor H antigens are more prone to induce GvL responses. This phenomenon renders the latter group of minor H antigens as curative tools for HSCT-based immunotherapy of hematological malignancies and disorders, in which minor H antigen-specific responses are enhanced in order to eradicate the malignant cells. This article describes the immunogenetics of minor H antigens and methods that have been developed to identify them. Moreover, it summarizes the clinical relevance of minor H antigens in transplantation, with special regards to allogeneic HSCT and solid-organ transplantation.

    Recruitment of more underrepresented minority students (black, Hispanic and native American) to increase racial diversity in the physician workforce is on the agenda for medical schools around the nation. The benefits of having a racially diverse class are indisputable. Minority physicians are more likely to provide care to minority, underserved, disadvantaged and low-income populations. Therefore, medical schools would benefit from diversity through utilizing strategies for recruitment of underrepresented minority (URM) students. Numerous recruitment strategies have been employed to increase the number of underrepresented minority students. However, formal collaboration with minority medical student organizations is an underutilized tool in the recruitment process. Many medical schools have informally used minority medical students and members of various minority organizations on campus in the recruitment process, but a formal collaboration which entails a strategic approach on using minority medical student organizations has yet to be included in the literature. This paper discusses the innovative collaboration between the University of Toledo College of Medicine (UTCOM) chapter of the Student National Medical Association (SNMA) and the college of medicine's admissions office to strategize a recruitment plan to increase the number of underrepresented minority students at the UTCOM. This paper suggests that minority medical student organizations, particularly the SNMA, can be used as a recruiting tool; hence, admissions offices cannot negate the usefulness of having formal involvement of minority medical student organizations as a recruiting tool. This approach may also be applicable to residency programs and other graduate professional fields with a severe shortage of URM students. PMID:17913109

    2016-01-01

    Introduction A growing body of evidence reveals higher rates of tobacco use among sexual minority populations relative to non-minority (“straight”) populations. This study seeks to more fully characterize this disparity by examining tobacco use by distinct sexual identities and gender to better understand patterns of: (1) cigarette smoking and smoking history; and (2) use of other tobacco products including cigars, pipes, hookah, e-cigarettes, and smokeless tobacco. Methods Data from the 2012–2013 National Adult Tobacco Survey, a random-digit dialed landline and cellular telephone survey of U.S. adults aged ≥18 years, were analyzed in 2014. A sexual minority category was created by combining gay, lesbian, and bisexual responses, along with those who selected an option for other non-heterosexual identities. Results Smoking prevalence was higher among sexual minority adults (27.4%) than straight adults (17.3%). Cigarette smoking was particularly high among bisexual women (36.0%). Sexual minority women started smoking and transitioned to daily smoking earlier than their straight peers. Use of other tobacco products was higher among sexual minority women: prevalence of e-cigarette (12.4%), hookah (10.3%), and cigar use (7.2%) was more than triple that of their straight female peers (3.4%, 2.5%, and 1.3%, respectively). Likewise, prevalence of sexual minority men’s e-cigarette (7.9%) and hookah (12.8%) use exceeded that of straight men (4.7% and 4.5%, respectively). Conclusions Tobacco use is significantly higher among sexual minority than straight adults, particularly among sexual minority women. These findings underscore the importance of tobacco control efforts designed to reach sexual minorities and highlight the heterogeneity of tobacco use within this population. PMID:26526162

  6. Asthma patient education opportunities in predominantly minority urban communities.

    Disenfranchised ethnic minority communities in the urban United States experience a high burden of asthma. Conventional office-based patient education often is insufficient to promote proper asthma management and coping practices responsive to minority patients' environments. This paper explores existing and alternative asthma information and education sources in three urban minority communities in western New York State to help design other practical educational interventions. Four focus groups (n = 59) and four town hall meetings (n = 109) were conducted in one Hispanic and two black communities. Focus groups included adult asthmatics or caretakers of asthmatics, and town meetings were open to all residents. A critical theory perspective informed the study. Asthma information and education sources, perceptions of asthma and ways of coping were elicited through semi-structured interviews. Data analysis followed a theory-driven immersion-crystallization approach. Several asthma education and information resources from the health care system, media, public institutions and communities were identified. Intervention recommendations highlighted asthma workshops that recognize participants as teachers and learners, offer social support, promote advocacy, are culturally appropriate and community-based and include health care professionals. Community-based, group health education couched on people's experiences and societal conditions offers unique opportunities for patient asthma care empowerment in minority urban communities.

    The heterocyclic C15 apocarotenoid 1 was isolated from mated cultures of the strains F986 (+) and F921 (−) of Blakeslea trispora. This new compound formed during sexual interaction is a minor constituent of the culture media and its structure was elucidated by spectroscopic data, including 2D-NMR. A plausible biosynthetic pathway involving a double degradation of β-carotene, followed by several oxidations of the resulting monocyclofarnesane C15 fragment is proposed.

    2016-10-01

    Compared to sexual minority men and heterosexual women, sexual minority women report elevated alcohol use in young adulthood. Heavy alcohol use and alcohol use disorders disproportionately affect sexual minority women across the lifespan, yet there is limited research investigating reasons for such associations. The present study investigates longitudinal associations between minority stress and both alcohol use as well as self-rated drinking consequences. Participants (N=1057) were self-identified lesbian (40.5%) and bisexual (59.5%) women between the ages of 18 to 25 recruited from across the U.S. using online advertisements. Participants completed four annual surveys. Hurdle mixed effects models were used to assess associations between minority stress and typical weekly drinking and drinking consequences one year later. Minority stress was not significantly associated with subsequent typical drinking. However, minority stress was significantly associated with having any alcohol consequences as well as the count of alcohol consequences one year later after controlling for covariates. Consistent with extant literature, this study provides evidence for a prospective association between minority stress experienced by sexual minority women and drinking consequences. This study also provides support for the potential impact of efforts to reduce minority stress faced by sexual minority women.

  10. Obesity in minority populations: an epidemiologic assessment.

    PubMed

    Kumanyika, S K

    1994-03-01

    This article reviews issues relating to the prevalence, health implications, and prevention and treatment perspectives of obesity in U.S racial and ethnic minority groups. The growing interest in obesity in minority populations reflects an awareness of the high prevalence of obesity among black, Hispanic, Asian and Pacific Islander and Native Americans as well as a generally increased interest in minority health. In addition, the fact that some aspects of obesity among minorities differ from those in whites suggests that new insights may be gained from studying obesity in diverse populations. However, there are many methodological problems to be overcome, including some that arise from the way minority groups are defined. Under the assumption that all obesity results from a period of sustained positive energy balance at the individual level, an epidemiologic explanation for the excess of obesity in minorities at the population level seems readily apparent. A surplus of obesity-promoting forces and a deficit of obesity-inhibiting forces, caused by secular changes in food availability and physical activity, accompany the early phases of modernization and economic advancement. The high prevalence of obesity in minority populations can be viewed as a function of the slope and timing of these secular changes. Genetic predisposition, cultural attitudes, and exposure to maternal obesity and diabetes in utero may be potentiating factors. In this context, interventions targeting individuals would seem inevitably to put racial and ethnic minority groups on the path toward the same weight control crisis now observed in the majority white population. This suggests that the underlying causes of the societal energy balance problem must be addressed at the population level in order for effective clinical approaches to be developed for minority populations with a high obesity prevalence.

    It is important for the field of physics that we draw our talent from the broadest pool. However, African Americans, Hispanic Americans, and Native Americans are substantially underrepresented in physics. Since summer research experiences are a useful tool to assist students in gaining entrance into graduate school, it is particularly important that underrepresented minority students are fully able to participate. The NSF REU program at Vanderbilt University is historically comprised of one half minority students. How this comes about and how we pro-actively recruit minority students will be described.

    Pleomorphic adenoma, a benign tumor often seen in ENT practice, arises either from minor as well from major salivary glands. 5-14% of tumors occur in minor glands. Sixteen cases of minor salivary gland pleomorphic adenomas are studied. Eight of them originate from the oral cavity: 6 from the palate, one from the lower lip and one from the cheek. Two oral adenomas were malignant. In 4 patients tumors occur in the nasal cavity and in two other patients--in the neck. The clinical and pathological features of these patients are presented. Special attention is given to malignant transformation and the rate of recurrence of the tumors.

    2009-10-07

    Analysis of the 2.4-{angstrom} resolution crystal structure of the large ribosomal subunit from Haloarcula marismortui reveals the existence of an abundant and ubiquitous structural motif that stabilizes RNA tertiary and quaternary structures. This motif is termed the A-minor motif, because it involves the insertion of the smooth, minor groove edges of adenines into the minor groove of neighboring helices, preferentially at C-G base pairs, where they form hydrogen bonds with one or both of the 2' OHs of those pairs. A-minor motifs stabilize contacts between RNA helices, interactions between loops and helices, and the conformations of junctions and tight turns. The interactions between the 3' terminal adenine of tRNAs bound in either the A site or the P site with 23S rRNA are examples of functionally significant A-minor interactions. The A-minor motif is by far the most abundant tertiary structure interaction in the large ribosomal subunit; 186 adenines in 23S and 5S rRNA participate, 68 of which are conserved. It may prove to be the universally most important long-range interaction in large RNA structures.

    Official language minorities (Francophones outside of Quebec and Anglophones in Quebec) make up about 6.4% of the Canadian population. Even though the Canadian constitution gives legal equality status to French and English, there is still room to ask if this equality is maintained in the health sector. In other words, do Francophone and Anglophone communities of Canada have the same health profiles regardless of their minority or majority status? Do they have access to the same health services and in the same conditions? The objective of this paper is to identify the health issues associated with belonging to a linguistic minority. Our research allows us to highlight the social and health disparities that can be attributed to belonging to a minority. In the Canadian context, which has two official languages, an equitable health policy will have to take into consideration language as a determinant of health. PMID:24289938

However, women's health advocacy in the United States does not consistently address problems specific to minority women. The underlying evolution and political strength of the women's health and minority health movements differ profoundly. Women of color comprise only one quarter of women's health movement constituents and are, on average, socioeconomically disadvantaged. Potential alliances may be inhibited by vestiges of historical racial and social divisions that detract from feelings of commonality and mutual support. Nevertheless, insufficient attention to minority women's issues undermines the legitimacy of the women's health movement and may prevent important advances that can be achieved only when diversity is fully considered.

  5. Faster Parameterized Algorithms for Minor Containment

    NASA Astrophysics Data System (ADS)

    Adler, Isolde; Dorn, Frederic; Fomin, Fedor V.; Sau, Ignasi; Thilikos, Dimitrios M.

    The theory of Graph Minors by Robertson and Seymour is one of the deepest and significant theories in modern Combinatorics. This theory has also a strong impact on the recent development of Algorithms, and several areas, like Parameterized Complexity, have roots in Graph Minors. Until very recently it was a common belief that Graph Minors Theory is mainly of theoretical importance. However, it appears that many deep results from Robertson and Seymour's theory can be also used in the design of practical algorithms. Minor containment testing is one of algorithmically most important and technical parts of the theory, and minor containment in graphs of bounded branchwidth is a basic ingredient of this algorithm. In order to implement minor containment testing on graphs of bounded branchwidth, Hicks [NETWORKS 04] described an algorithm, that in time O(3^{k^2}\\cdot (h+k-1)!\\cdot m) decides if a graph G with m edges and branchwidth k, contains a fixed graph H on h vertices as a minor. That algorithm follows the ideas introduced by Robertson and Seymour in [J'CTSB 95]. In this work we improve the dependence on k of Hicks' result by showing that checking if H is a minor of G can be done in time O(2^{(2k +1 )\\cdot log k} \\cdot h^{2k} \\cdot 2^{2h^2} \\cdot m). Our approach is based on a combinatorial object called rooted packing, which captures the properties of the potential models of subgraphs of H that we seek in our dynamic programming algorithm. This formulation with rooted packings allows us to speed up the algorithm when G is embedded in a fixed surface, obtaining the first single-exponential algorithm for minor containment testing. Namely, it runs in time 2^{O(k)} \\cdot h^{2k} \\cdot 2^{O(h)} \\cdot n, with n = |V(G)|. Finally, we show that slight modifications of our algorithm permit to solve some related problems within the same time bounds, like induced minor or contraction minor containment.

  6. Minor Illnesses, Temperament, and Toddler Social Functioning

    Kolak, Amy M.; Frey, Tara J.; Brown, Chloe A.

    2013-01-01

    Research findings Minor illnesses, such as upper respiratory infections, stomachaches, and fevers, have been associated with children’s decreased activity and increased irritability. Mothers of children who are frequently ill report more child behavior problems; however, previous research in this area has yet to simultaneously examine children’s temperament. This investigation examined whether experience with recurrent, minor illnesses and negative emotionality worked together to predict young children’s social functioning. This multi-method study utilized a sample of 110 daycare-attending children. Nurses went to the daycare centers weekly to perform health screens on the participating children. Minor illness experience was represented using a proportion created by dividing the number of illness diagnoses by the total number of health screenings completed from the time the child was enrolled in the study through his or her second birthday. Toddlers’ negative emotionality and social behavior were assessed using mothers’ and fathers’ reports. The two dimensions of negative emotionality and minor illness experience operated in different ways such that anger worked additively with minor illness experience and fearfulness interacted with minor illness experience to predict social behavior. Children who were described as more temperamentally angry displayed less social competence especially when they also experienced high proportions of minor illness. Temperamentally fearful children exhibited more externalizing problems when they experienced a higher frequency of illness whereas fearfulness was not associated to externalizing problems for children who experienced low proportions of illness. Practice or Policy Children’s frequent experience with minor illnesses combined with negative emotionality appears to place toddlers at a heightened risk for exhibiting behavior problems. These findings have implications for child and family well-being as well as

    Transient photoluminescence is used to measure the minority carrier lifetime on n-type and p-type InP wafers. The measurements show that unprocessed InP wafers have very high minority carrier lifetimes. Lifetimes of 200 ns and 700 ns were observed for lightly-doped p- and n-type material respectively. Lifetimes over 5 ns were found in heavily doped n-type material.

    Until recently, pancreas divisum represented a major technical barrier to a complete evaluation of pancreatic ductal anatomy. Technical refinements have now made it possible to achieve minor papilla cannulation and dorsal ductography in more than 90% of attempts. In 120 consecutive dorsal ductograms, structural pathology was demonstrated in 36 subjects (30%): chronic pancreatitis in 23, pancreatic stones in 10, pseudocyst(s) in 4, ductal "cut-off" in 7, pancreatic cancer in 3, and partial agenesis in 1 (some patients had more than one finding). For patients in whom alcohol abuse was excluded, ductal pathology was present in 25%. Abnormal ventral ductograms were present in only 8% of cases, demonstrating that dorsal ductography has an appreciable additional diagnostic yield. When the clinical situation indicates the need for pancreatography, minor papilla cannulation should be performed if major papilla cannulation fails or reveals only the ventral pancreatogram of pancreas divisum.

    1980-12-15

    In Part I of this report the basis for the optimal development of new business opportunities for minorities in nuclear energy programs is defined within the successful completion of all contract tasks. The basis presented consists of an identification of a set of qualified minority-owned small businesses, a defined reservoir of highly trained minorities with applicable expertise, a policy context for the development of opportunities, and a proposed networking structure for information transfer/professional development. In Part II a contractor-focused analysis of the structure of the nuclear industry, a breakdown of the DOE nuclear program by region and functional area, and a directory of minority-owned small businesses by region are presented.

  11. We Can Recruit Minorities Into The Geosciences

    2011-12-01

    Despite the dismal numbers, efforts to recruit minorities into the geosciences are improving, thanks in part to NSF's "Opportunities for Enhancing Diversity in the Geosciences" (OEDG) initiative. At Wesleyan University, a small liberal arts college in Connecticut, we have significantly increased our recruitment of minority students. Twenty percent (four students) of the class of 2013 are African American. Most of the recruitment is done on an individual basis and working in conjunction with the "Dean for Diversity and Student Engagement" and courting minority students in introductory classes. The Dean for Diversity and Student Engagement is aware of our interest in increasing diversity and that we are able to hire minority students during the academic year and through the summer with OEDG funds. When she identifies minority students who might be interested in the geosciences, she refers them to faculty in the Earth and Environmental Sciences Department. Our faculty can provide employment, mentoring and a variety of geo-related experiences. Courting students in introductory courses can include inviting them to lunch or other activity, and attending sports, theater or dance events in which they are participating. Not all efforts result in new majors. Courses in ancillary sciences may be stumbling blocks and higher grades in less demanding courses have lured some students into other majors. Nevertheless, we now have a large enough cohort of minority students so that minority students from other majors visit their friends in our labs. A critical mass? Even a student, who chooses another major, may continue an interest in geoscience and through outreach efforts and discussions with younger family members, may provide a bridge that becomes a conduit for future students.

  12. The truth about mentoring minorities. Race matters.

    Thomas, D A

    2001-04-01

    Diversity has become a top priority in corporate America. Despite corporations' best intentions, however, many have failed to achieve a racial mix at the top levels of management. Some have revolving doors for talented minorities, recruiting the best and brightest, only to see them leave, frustrated by their experiences. Others are able to retain high-potential professionals of color but find them mired in middle management. To understand the different career trajectories of whites and minorities, David Thomas studied the progression of racial minorities at three large U.S. corporations. Here, he explains the three career stages that all professionals advance through, and he discusses why promising white professionals tend to enter fast tracks early in their careers, whereas high-potential minorities typically take off after they have reached middle management. Thomas's research shows that minorities who advance the furthest share one characteristic: a strong network of mentors and corporate sponsors. He found that minorities who plateaued in middle management received mentoring that was basically instructional; it helped them to develop skills. By contrast, minorities who became executives enjoyed fuller developmental relationships with their mentors. Thomas explains the types of support mentors provide for their protégés and outlines the challenges of mentoring across racial lines. Specifically, he addresses negative stereotypes, public scrutiny, difficulty with role modeling, and peer resentment. Finally, Thomas challenges the notion that the job of mentors begins and ends with their one-on-one relationships with their protégés. He offers concrete advice on how mentors can support broader initiatives at their organizations to create and enhance conditions that foster the upward mobility of professionals of color.

  13. The shape of the DNA minor groove directs binding by the DNA-bending protein Fis

    The bacterial nucleoid-associated protein Fis regulates diverse reactions by bending DNA and through DNA-dependent interactions with other control proteins and enzymes. In addition to dynamic nonspecific binding to DNA, Fis forms stable complexes with DNA segments that share little sequence conservation. Here we report the first crystal structures of Fis bound to high- and low-affinity 27-base-pair DNA sites. These 11 structures reveal that Fis selects targets primarily through indirect recognition mechanisms involving the shape of the minor groove and sequence-dependent induced fits over adjacent major groove interfaces. The DNA shows an overall curvature of {approx}65{sup o}, and the unprecedented close spacing between helix-turn-helix motifs present in the apodimer is accommodated by severe compression of the central minor groove. In silico DNA structure models show that only the roll, twist, and slide parameters are sufficient to reproduce the changes in minor groove widths and recreate the curved Fis-bound DNA structure. Models based on naked DNA structures suggest that Fis initially selects DNA targets with intrinsically narrow minor grooves using the separation between helix-turn-helix motifs in the Fis dimer as a ruler. Then Fis further compresses the minor groove and bends the DNA to generate the bound structure.

    HIV infection among racial and ethnic minorities is an ongoing health crisis. The disproportionate impact of HIV infection on racial and ethnic minorities has affected communities already struggling with many social and economic challenges, such as poverty, substance abuse, homelessness,unequal access to health care, and unequal treatment once in the health care system. Superimposed on these challenges is HIV infection, the transmission of which is facilitated by many of these factors. Although the epidemic is disproportionately affecting all racial and ethnic minorities, within these minority populations women are particularly affected. The care and management of racial and ethnic minorities who have HIV infection has been complicated by the unequal access to health care and the unequal treatment once enrolled in health care. Health insurance status, lack of concordance between the race of the patient and the provider, and satisfaction with the quality of their care all impact on treatment outcomes in this population. In addition, the provider must be aware of the many comorbid conditions that may affect the delivery of care to minority patients living with HIV infection: depression, substance and alcohol abuse, and posttraumatic stress disorders. The impact of these comorbid conditions on the therapeutic relationship, including treatment and adherence, warrants screening for these disorders and treating them when identified. Because the patient provider relationship has been repeatedly identified as a predictor of higher adherence, developing and maintaining a strong therapeutic alliance is critical. Participation of racial and ethnic minorities in HIV clinical trials, as in other disease states, has been very poor. Racial and ethnic minorities have been chronically underrepresented in HIV clinical trials, despite their overrepresentation in the HIV epidemiology. This underrepresentation seems to be the result of a combination of factors including (1) provider

  15. MINORITY STRESS, POSITIVE IDENTITY DEVELOPMENT, AND DEPRESSIVE SYMPTOMS: IMPLICATIONS FOR RESILIENCE AMONG SEXUAL MINORITY MALE YOUTH

    Introduction Minority stress processes have been shown to have significant associations with negative mental health outcomes among sexual minority populations. Given that adversity may be experienced growing up as a sexual minority in heteronormative, if not heterosexist, environments, our research on resilience among sexual minority male youth proposes that positive identity development may buffer the effects of a range of minority stress processes. Methods An ethnically diverse sample of 200 sexual minority males ages 16–24 (mean age, 20.9 years) was recruited using mixed recruitment methods. We developed and tested two new measures: concealment stress during adolescence and sexual minority-related positive identity development. We then tested a path model that assessed the effects of minority stressors, positive identity development, and social support on major depressive symptoms. Results Experience of stigma was associated with internalized homophobia (β=.138, p<.05) and major depressive symptoms (β=1.076, OR=2.933, p<.001), and internalized homophobia partially mediated experience’s effects on major depression (β=.773, OR=2.167, p<.001). Concealment stress was associated with positive identity development (β=.155, p<.05) and internalized homophobia (β=.418, p<.001), and positive identity development partially mediated concealment stress’s effects on internalized homophobia (β=−.527, p<.001). Concealment stress demonstrated a direct effect on major depression (β=1.400, OR=4.056, p<.001), and indirect paths to social support through positive identity development. Conclusions With these results, we offer an exploratory model that empirically identifies significant paths among minority stress dimensions, positive identity development, and major depressive symptoms. This study helps further our understanding of minority stress, identity development, and resources of resilience among sexual minority male youth. PMID:26478901

    1990-03-01

    Despite recent attention to minority student recruitment and retention, data on predicting the success of minority medical students are scarce. Traditional predictors (college grades and scores on the Medical College Admission Test) have modest correlations with medical school grades and scores on the National Board of Medical Examiners examination for minority students. Nonetheless, admission committees also consider nontraditional variables when selecting minority students. Measures of nontraditional variables seem to assess types of intelligence not covered by traditional means. A system of organizing nontraditional or noncognitive variables into eight dimensions is proposed. The dimensions are self-concept, realistic, self-appraisal, understanding and dealing with racism, long-range goals, having a strong support person, showing leadership, having community involvement, and nontraditional knowledge acquired. Further, assessment should place more emphasis on recognizing and defining problems and on performance rather than knowledge. Combining traditional and nontraditional methods is best in selecting minority students, and sufficiently well developed measures exist in each area to make this a practical recommendation for any admission program.

  17. A Relational Model of Sexual Minority Mental and Physical Health: The Negative Effects of Shame on Relationships, Loneliness, and Health

    2015-01-01

    Sexual minorities (e.g., lesbians, gay men, bisexual individuals) are at higher risk for mental and physical health disparities than heterosexuals, and some of these disparities relate to minority stressors such as discrimination. Yet, there is little research elucidating pathways that predict health or that promote resiliency among sexual minorities. Building on the minority stress model, the present study utilized relational cultural theory to situate sexual minority health within a relational framework. Specifically, the study tested mediators of the relationships between distal (i.e., discrimination, rejection, victimization) and proximal stressors (i.e., internalized homophobia, sexual orientation concealment) and psychological and physical distress for sexual minorities. Among 719 sexual minority adults, structural equation modeling analyses were used to test four models reflecting the mediating effects of shame, poorer relationships with a close peer and the LGBT community, and loneliness on the associations between minority stressors and psychological distress (i.e., depression and anxiety) and physical distress (i.e., distressing physical symptoms). As hypothesized, the associations between distal and proximal minority stressors and distress were mediated by shame, poorer relationships with a close peer and the LGBT community, and loneliness. Findings underscore the possible relational and interpersonal mechanisms by which sexual minority stressors lead to psychological and physical distress. PMID:26010289

    PubMed

    Gabard, Donald L

    2007-01-01

    Although race is a social construct with no scientific credibility, it is a powerful predictor of diminished health outcomes and health care delivery in the United States. Minorities who enter health professions provide a disproportionate quantity of health care services to minorities, the underserved, and poor. The goal of having a health care delivery system with similar demographics to the population it serves is seriously lacking in most health care professions. The author of this commentary proposes that health care educators should be more aggressive in admitting and recruiting students from minority communities through the use of affirmative action. The recent U.S. Supreme Court ruling, Grutter v. Bollinger, not only supports this approach but also gives guidance for implementation. Under the general category of admission strategies, two strategies are proposed: (1) a defensible structure for admission using race/ethnicity as a factor and (2) expanded criteria for student selection. Under recruitment strategies, four strategies are offered: (1) outreach to kindergarten through 12th grade, (2) better informing school career counselors, (3) advertising possibilities, and (4) community involvement through local school boards. Because affirmative action in admissions is the most controversial and complex set of strategies, this report focuses particularly on this area. PMID:17941411

    2012-01-01

    This article reviews a selection of undergraduate programs intended to increase successful minority participation in science, technology, engineering, and mathematics majors, potentially leading to biomedical careers. The object is to examine their structure, consider how well they address the issues of the target population, and assess the extent to which they have met/meet their goals. As a means of conducting this review, the first step is to examine the concepts used as the building blocks for program design. These concepts are found in a shared, yet often undefined, vocabulary used in most undergraduate programs for minority students. The hypothesis is that a shared vocabulary obscures a broad range of meaning and interpretation that has serious ramifications affecting student success. How these building blocks are understood and implemented strongly reflects the institution where the program is housed. The discussion further considers the nature of a number of programs created by the National Science Foundation and the National Institutes of Health specifically for underrepresented minority students and examines one program in detail, the University of California Berkeley's National Science Foundation Research Experience for Undergraduates Program in Molecular, Cell, and Evolutionary Biology. The characteristics of federally organized programs and the Research Experience for Undergraduates are contrasted with 2 very successful student-centered local programs based on a different conceptual model.

    Purpose Very few studies have examined mental disorders among male sexual minority youth. We describe demographic correlates, comorbidity, and history of mental disorders and suicidality in a large sample of male sexual minority youth. Methods Structured diagnostic interviews were conducted with 449 racially diverse, urban sexual minority males, ages 16-20, who were recruited using a social-network driven sampling methodology. Results Lifetime major depressive episode (MDE) affected 33.2% of the youth. Lifetime conduct disorder (23.6%), alcohol abuse/dependence (19.6%), posttraumatic stress disorder (PTSD; 16.0%), and nicotine dependence (10.7%) were also common. Black participants were less likely than White participants to be diagnosed with lifetime MDE, alcohol abuse/dependence, nicotine dependence, suicidal ideation, and anorexia, as well as past 12-month alcohol abuse/dependence (OR's range from .08-.46). Relative to participants identifying as gay, bisexual identified youth were at higher risk for lifetime PTSD (OR=2.04), and participants who did not identify as gay or bisexual were at higher risk for both lifetime and past 12-month nicotine dependence (OR's = 4.36 and 3.46, respectively). Most participants with mental disorders never received treatment, and comorbidity was common. Conclusions MDE, conduct disorder, alcohol abuse/dependence, PTSD, and nicotine dependence are common and infrequently treated in young sexual minority men. Some within-group disparities emerged, suggesting factors related to racial background and self-identification may help to understand resilience to the unique stressors experienced by these young men.

    2016-05-11

    The vast majority out of the 20 000 patients annually hospitalized after sustaining a head injury belong to the minor head injury/cerebral concussion continuum. Fortunately, most of the patients show full recovery after days to weeks. However, about 15 % of these patients suffer from prolonged up to permanent sequels potentially impairing their quality of life to a considerable extent. This especially holds true for those who suffer from recurrent minor head injuries (i.e. victims from contact sport accidents). Unfortunately, many of these patients are never diagnosed in an appropriate way and therefore looked at as hypochondriacs or simulants. This prevents adequate rehabilitation and support. This review aims to present current knowledge about pathophysiology and clinical features of minor head injuries and to give some information about diagnostics and treatment according to current guidelines.

    Background: Admissions departments at chiropractic colleges across the United States are under continual pressure to recruit students. The underrepresented minority populations in the United States are potential markets for chiropractic patients, students, and doctors. Objective: To assess the current diversity recruiting practices of the chiropractic colleges. Methods: Directors of admissions of the chiropractic colleges were polled to identify recruiting programs and their success. Results: Sixteen of the 17 colleges were polled. Nine of the respondents had no program for targeted underserved populations and seven did have such a program. Five colleges employed several methods to work with universities to recruit underserved populations. Other strategies included outreach via student groups and alumni recruiters. Conclusion: Programs to attract minority students can be created and infrastructure can be provided but they are nearly useless without role models. Encouraging alumni participation to raise awareness of chiropractic in minority communities may be a step toward a profession more reflective of America’s population. PMID:18483633

    Three basic studies, using spectrographic methods, have been used to establish the occurrence of minor elements in natural waters. One study, of oceanborne chemicals in principal rivers, has established a method for the quantitative analysis of many minor elements. Strontium, barium, lithium, rubidium, chromium, nickel, copper, lead, boron, titanium, molybdenum, manganese, and vanadium occur most frequently in measurable quantities. Reconnaissance of the strontium in surface waters of the United States, shows that surface waters in parts of northern and western Texas and southern New Mexico and Arizona are comparatively high in strontium. A study of minor elements in selected waters of California is continuing. Assessment of preliminary data on uranium and radium in waters is facilitated by grouping data for 10 geotectonic regions of the United States.

    Children absconding from countries of conflict and war are often not able to document their age. When an age is given, it is frequently untraceable or poorly documented and therefore questioned by immigration authorities. Consequently many countries perform age estimations on these children. Provision of ethical practice during the age estimation investigation of unaccompanied minors is considered from different angles: (1) The UN convention on children's rights, formulating specific rights, protection, support, healthcare and education for unaccompanied minors. (2) Since most age estimation investigations are based on medical examination, the four basic principles of biomedical ethics, namely autonomy, beneficence, non-malevolence, justice. (3) The use of medicine for non treatment purposes. (4) How age estimates with highest accuracy in age prediction can be obtained. Ethical practice in age estimation of unaccompanied minors is achieved when different but related aspects are searched, evaluated, weighted in importance and subsequently combined. However this is not always feasible and unanswered questions remain.

    2015-06-01

    Although research on disclosure following intimate partner violence (IPV) victimization is burgeoning, sexual minority young adults' (lesbian, gay, bisexual, queer, questioning, etc.; LGBQ+) experiences have not received equal attention. The current study employed the minority stress framework to examine disclosure experiences of LGBQ+ college students across the United States reporting physical IPV victimization within their current relationship (n = 77). Participants completed measures assessing minority stress and IPV disclosure, and answered open-ended questions regarding the most and least helpful persons/responses to disclosure or reasons for non-disclosure. Results indicated that approximately one-third (35 %) of victims disclosed to at least one person, with friends being the most common recipients. Thematic analyses indicated that talking or listening to the victim was considered the most helpful response and not understanding the situation least helpful. Reasons for non-disclosure centered on themes of the victims' perception that the IPV was not a big deal. Quantitative findings regarding physical IPV disclosure indicated that non-disclosers experienced greater minority stress than disclosers. The current study suggests the presence of differences between sexual minority (i.e., LGBQ +persons) and non-sexual minority persons, as well as between LGBQ+ young adults/college students and older adults and presents a theoretical structure (i.e., minority stress framework) through which these differences may be understood.

    2012-01-01

    Background Asthma outcomes are generally worse for ethnic minority children. Cultural competence training is an instrument for improving healthcare for ethnic minority patients. To develop effective training, we explored the mechanisms in paediatric asthma care for ethnic minority patients that lead to deficiencies in the care process. Methods We conducted semi-structured interviews on care for ethnic minority children with asthma (aged 4-10 years) with paediatricians (n = 13) and nurses (n = 3) in three hospitals. Interviews were analysed qualitatively with a framework method, using a cultural competence model. Results Respondents mentioned patient non-adherence as the central problem in asthma care. They related non-adherence in children from ethnic minority backgrounds to social context factors, difficulties in understanding the chronic nature of asthma, and parents’ language barriers. Reactions reported by respondents to patients’ non-adherence included retrieving additional information, providing biomedical information, occasionally providing referrals for social context issues, and using informal interpreters. Conclusions This study provides keys to improve the quality of specialist paediatric asthma care to ethnic minority children, mainly related to non-adherence. Care providers do not consciously recognise all the mechanisms that lead to deficiencies in culturally competent asthma care they provide to ethnic minority children (e.g. communicating mainly from a biomedical perspective and using mostly informal interpreters). Therefore, the learning objectives of cultural competence training should reflect issues that care providers are aware of as well as issues they are unaware of. PMID:22551452

    Objectives Research consistently demonstrates that sexual minority status is associated with increased risk of problematic substance use. Existing literature in this area has focused on group-specific minority stress factors (e.g., victimization and internalized heterosexism). However, no known research has tested the incremental validity of personality traits as predictors of substance use beyond identified group-specific risk factors. Methods A sample of 704 sexual minority adults were recruited nationally from LGBTQQ community organizations and social networking websites and asked to complete an online survey containing measures of personality, sexual minority stress, and substance use. Results Hierarchical regression models were constructed to test the incremental predictive validity of Five-Factor personality traits over and above known sexual minority risk factors. Consistent with hypotheses, extraversion and conscientiousness were associated with drug and alcohol use after accounting for minority stress factors, and all factors except agreeableness were associated with substance use at the bivariate level of analysis. Conclusion Future research should seek to better understand the role of normal personality structures and processes conferring risk for substance use among sexual minorities. PMID:25347022

  16. Some Minorants and Majorants of Random Walks and Levy Processes

    majorant, which is then used to find a complete description of the concave majorant of a walk of infinite length. In the case where subsets of increments may have the same arithmetic mean (the more general case mentioned above), we investigate three nested compositions that naturally arise from our construction of the concave majorant. This chapter is based on [4], which was co-written with Jim Pitman. In Chapter 3, we study the Lipschitz minorant of a Levy process. For alpha > 0, the alpha-Lipschitz minorant of a function f : R→R is the greatest function m : R→R such that m ≤ f and | m(s) - m(t)| ≤ alpha |s - t| for all s, t ∈ R should such a function exist. If X = Xtt∈ R is a real-valued Levy process that is not pure linear drift with slope +/-alpha, then the sample paths of X have an alpha-Lipschitz minorant almost surely if and only if | E [X1]| < alpha. Denoting the minorant by M, we investigate properties of the random closed set Z := {t ∈ R : Mt = {Xt ∧ Xt-}, which, since it is regenerative and stationary, has the distribution of the closed range of some subordinator "made stationary" in a suitable sense. We give conditions for the contact set Z to be countable or to have zero Lebesgue measure, and we obtain formulas that characterize the Levy measure of the associated subordinator. We study the limit of Z as alpha → infinity and find for the so-called abrupt Levy processes introduced by Vigon that this limit is the set of local infima of X. When X is a Brownian motion with drift beta such that |beta| < alpha, we calculate explicitly the densities of various random variables related to the minorant. This chapter is based on [2], which was co-written with Steven N. Evans. Finally, in Chapter 4 we study the structure of the shocks for the inviscid Burgers equation in dimension 1 when the initial velocity is given by Levy noise, or equivalently when the initial potential is a two-sided Levy process This shock structure turns out to give rise to a

  17. Transcultural psychiatry, ethnic minorities and marginalization.

    PubMed

    Farrington, A

    Cultural and racial bias has been woven into the fabric of Western psychiatry in its historic development. Western psychiatry emphasizes the medical model as being fundamental to the discipline. Many communities in large cities and industrial areas have become multicultural and multiracial. Culture-bound syndromes are not specific to non-Western ethnic minorities. Black people are overrepresented among psychiatric patients in institutions. Mental health services for ethnic minorities have been haphazard and inconsistent. Cultural experiences and the practical realities of racism are overdue their recognition.

    2008-10-01

    We examine the possibility that a certain class of neutrino mass matrices, namely, those with two independent vanishing minors in the flavor basis, regardless of being invertible or not, is sufficient to describe current data. We compute generic formulas for the ratios of the neutrino masses and for the Majorana phases. We find that seven textures with two vanishing minors can accommodate the experimental data. We present an estimate of the mass matrix for these patterns. All of the possible textures can be dynamically generated through the seesaw mechanism augmented with a discrete Abelian symmetry.

  1. Communicating with older ethnic minority patients.

    In a time of increasing cultural diversity, it is essential that healthcare professionals respond by providing culturally competent care. Healthcare professionals must recognise the diverse needs of people from ethnic minority communities to ensure that they receive equal standards of care. This is particularly pertinent when providing care for older ethnic minority patients who may not be fluent in English. This article focuses on the need to communicate effectively with this group of patients to meet their health and social care needs, with the ultimate aim of improving patient outcomes. PMID:24894254

    Objective To estimate the prevalence and identify correlates of depressive symptoms among immigrant Latino sexual minorities. Methods Respondent-driven sampling (RDS) was used to estimate the prevalence of depressive symptoms, and univariate and multivariable analyses were conducted to identify correlates of depressive symptoms. Results Unweighted and RDS-weighted prevalence estimates of depressive symptoms were 69.2% and 74.8%, respectively. In the multivariable analysis, low social support, sexual compulsivity, and high self-esteem were significantly associated with increased depressive symptoms. Conclusions A need exists for culturally congruent mental health services for immigrant Latino sexual minorities in the southern United States. PMID:23985187

  3. Adenomatoid hyperplasia of oral minor salivary glands.

    PubMed

    Barrett, A W; Speight, P M

    1995-04-01

    Adenomatoid hyperplasia is a rare cause of swelling of the oral minor salivary glands, but is of significance because of its clinical resemblance to salivary gland tumors. The histologic appearance is one of benign hyperplasia and hypertrophy of the minor mucous glands. The clinical and histologic features of 20 new cases are reported, 19 of which occurred in the hard or soft palate. The cause of adenomatoid hyperplasia has hitherto been unclear, but the observation that 14 subjects were tobacco smokers or denture wearers, or both, suggests chronic, local trauma may be an important factor in the development of the condition.

    Magnetic resonance imaging evaluations of nine histopathologically confirmed minor salivary gland tumors were made retrospectively and compared with evaluations of images obtained by computed tomography. All tumors had low-to-intermediate T1 signal intensities and intermediate-to-high T2 signal intensities. Malignant tumors had an irregular margin in all but one case. Benign tumors invariably had well-defined margins. In terms of tumor margination, the magnetic resonance imaging findings correlated well with the histopathologic findings. Magnetic resonance imaging demonstrated the internal architecture of the minor salivary gland tumors multidirectionally and was superior to computed tomography in this respect and in the ability to locate the tumors.

    Compounds containing the tricyclic dibenzo[b,e]azepine system have potential activity in the treatment of a number of diseases. Continuing with our studies on the synthesis of new small and potentially bioactive molecules, a synthetic route, involving acid-catalysed intramolecular Friedel-Crafts cyclization, to the readily separable diastereoisomers of 11-ethyl-6,11-dihydro-5H-dibenzo[b,e]azepine-6-carboxamide, a potentially useful precursor in the synthesis of analogues of some anti-allergenic, antidepressant and antihistaminic drugs currently in use, has been developed starting from 2-allylphenylamine and methyl 2-bromo-2-phenylacetate and proceeding via racemic methyl 2-[(2-allylphenyl)amino]-2-phenylacetate (A) and racemic 2-[(2-allylphenyl)amino]-2-phenylacetamide (B), to give the two diastereoisomers (I) and (II), C17H18N2O. Isomers (I) and (II), and their precursors (A) and (B), have all been fully characterized spectroscopically. Structure analysis of the minor isomer (I) shows that it has the (6RS,11RS) configuration, and that the azepine ring adopts a conformation intermediate between the boat and twist-boat forms, with the carboxamide and ethyl substituents both occupying quasi-equatorial sites. The molecules of (I) are linked by a combination of N-H...O, N-H...π(arene) and C-H...π(arene) hydrogen bonds to form complex sheets. Comparisons are made with the structures of some related compounds. PMID:27377276

  18. NMR studies of DNA oligomers and their interactions with minor groove binding ligands

    SciTech Connect

    Fagan, P A

    1996-05-01

    The cationic peptide ligands distamycin and netropsin bind noncovalently to the minor groove of DNA. The binding site, orientation, stoichiometry, and qualitative affinity of distamycin binding to several short DNA oligomers were investigated by NMR spectroscopy. The oligomers studied contain A,T-rich or I,C-rich binding sites, where I = 2-desaminodeoxyguanosine. I{center_dot}C base pairs are functional analogs of A{center_dot}T base pairs in the minor groove. The different behaviors exhibited by distamycin and netropsin binding to various DNA sequences suggested that these ligands are sensitive probes of DNA structure. For sites of five or more base pairs, distamycin can form 1:1 or 2:1 ligand:DNA complexes. Cooperativity in distamycin binding is low in sites such as AAAAA which has narrow minor grooves, and is higher in sites with wider minor grooves such as ATATAT. The distamycin binding and base pair opening lifetimes of I,C-containing DNA oligomers suggest that the I,C minor groove is structurally different from the A,T minor groove. Molecules which direct chemistry to a specific DNA sequence could be used as antiviral compounds, diagnostic probes, or molecular biology tools. The author studied two ligands in which reactive groups were tethered to a distamycin to increase the sequence specificity of the reactive agent.

  19. Macro-Level Approaches to HIV Prevention Among Ethnic Minority Youth

    PubMed Central

    Prado, Guillermo; Lightfoot, Marguerita; Brown, C. Hendricks

    2013-01-01

    The HIV epidemic continues to disproportionately affect ethnic minority youth. These disconcerting health disparities indicate that although existing HIV preventive strategies for ethnic minority youth have been efficacious, they have not significantly reduced the impact of the epidemic in this population. Macro-level interventions, such as structural or policy interventions, have the potential to impact the HIV epidemic at a population level, and thus reduce the HIV health disparities that exist among ethnic minority youth and other segments of the U.S. population. This article calls for a paradigm shift to develop, evaluate, and disseminate interventions that target upstream/macro-level factors or that, at a minimum, integrate both a macro and individual level perspective. The article also discusses the challenges in developing and evaluating such interventions. Psychologists and other behavioral scientists can play a critical role in reducing the impact of HIV on ethnic minority youth by integrating macro-level approaches to future HIV prevention strategies.

    A survey of minority allied health faculty is being conducted by the Equal Representation in Allied Health Committee of the American Society of Allied Health Professions. Initiated in the spring of 1988, survey data collection is ongoing. The questionnaire was designed to gather demographic information as well as information regarding interests in professional and development/leadership workshops. This paper reports results from 106 valid returns. The majority of respondents were black females employed at four-year universities/colleges at the rank of assistant professor. An analysis of data using the chi-square statistic revealed a statistically significant but weak correlational relationship between sex and highest degree completed; academic rank and highest degree completed; academic rank and experience in allied health education; and tenure status and experience in allied health education. Cross tabulations between other variables were inconclusive. The data would suggest that the percentage of minority faculty with tenure appeared to exceed expectations when compared with results of previous studies of allied health faculty. Suggestions by respondents for professional development workshops included a variety of topics: management/administration skills, clinical skills, minority recruitment/retention, curriculum development/instructional design, and career advancement/leadership. Additional activities are needed to expand the existing data base and to promote networking among minority faculty. PMID:2737940

A substantial body of evidence clearly indicates the differences in incidence of psychosis, affective disorders and suicidal tendencies in members of minority groups compared to the rest of the population. Relevant statistical data will be presented and examined from both a biological and socio-cultural point of view. Hoffman's Social Deafferentation Hypothesis will be introduced as a possible explanation of high incidence of psychotic disorders in immigrants. Subsequently, socio-cultural factors will receive attention. Acculturation and identity issues will be taken into account with regards to the data suggesting that these are second generation immigrants that suffer from mental health disorders most. The fact of being discriminated against and being exposed to negative social messages regarding one's group of reference will also be taken into consideration. Moreover, ethnic minorities will be compared on this dimension with other groups discriminated against, such as women and sexual minorities.

  7. Language choice in a minority school

    NASA Astrophysics Data System (ADS)

    Byram, M. S.

    1985-12-01

    This article arises from fieldwork in a school of the German minority in South Jutland, Denmark. The minority exists as a result of frontier changes between Germany and Denmark, most recently in 1920. A referendum held in that year as a result of the Treaty of Versailles left a cultural and linguistic minority which, by today, has its own school system, politial party and cultural rights. The research was carried out using qualitative, ethnographic methods and the article focuses on one aspect, namely the issue of language use by bilingual pupils in one of the minority's schools. Pupils' choice of Danish or German in different situations within and outside schools was analyzed through the use of language diaries, informal interviews, and participant observation. The diary entries are analyzed and commented on in the light of interviews and observations. Pupils' awareness of their language use is not static but becomes dynamic as a consequence of being involved in research. The implications of this for educational policy are considered in the context of current developments in language education in British schools.

    Abbey, L M; Witorsch, R J

    1985-07-01

    An immunohistochemical study of 15 minor salivary gland tumors was initiated to determine if prolactin binding occurred in these tissues. Eight benign mixed tumors (BMT) and 7 adenoid cystic carcinomas (ACC) were selected at random from the surgical biopsy service of the MCV/VCU School of Dentistry, Department of Oral Pathology. The specimens were cut and mounted on slides along with sections of rat pituitary and rat ventral prostate which served as methodologic controls. Experimental specimens were incubated for 24 hours with varying concentrations of highly purified (iodination grade) rat prolactin; controls were incubated with vehicle. Following incubation the specimens were stained according to the Sternberger peroxidase-antiperoxidase method. Results showed dose-dependent staining for prolactin binding sites in 7 of 8 BMTs and 5 of 7 ACCs. The staining was wider in distribution than we observed in normal human minor salivary gland tissue. Binding was confined primarily to cells of duct origin in both types of tumor. In individual cells, staining was observed in diffuse cytoplasmic and perinuclear locations as well as in nuclei and apical regions. We conclude that two minor salivary gland neoplasms (BMT and ACC) exhibit prolactin binding at different cellular locations and in a more widespread pattern than was observed in normal minor salivary gland.

  13. Quantum annealing correction with minor embedding

    Quantum annealing provides a promising route for the development of quantum optimization devices, but the usefulness of such devices will be limited in part by the range of implementable problems as dictated by hardware constraints. To overcome constraints imposed by restricted connectivity between qubits, a larger set of interactions can be approximated using minor embedding techniques whereby several physical qubits are used to represent a single logical qubit. However, minor embedding introduces new types of errors due to its approximate nature. We introduce and study quantum annealing correction schemes designed to improve the performance of quantum annealers in conjunction with minor embedding, thus leading to a hybrid scheme defined over an encoded graph. We argue that this scheme can be efficiently decoded using an energy minimization technique provided the density of errors does not exceed the per-site percolation threshold of the encoded graph. We test the hybrid scheme using a D-Wave Two processor on problems for which the encoded graph is a two-level grid and the Ising model is known to be NP-hard. The problems we consider are frustrated Ising model problem instances with "planted" (a priori known) solutions. Applied in conjunction with optimized energy penalties and decoding techniques, we find that this approach enables the quantum annealer to solve minor embedded instances with significantly higher success probability than it would without error correction. Our work demonstrates that quantum annealing correction can and should be used to improve the robustness of quantum annealing not only for natively embeddable problems but also when minor embedding is used to extend the connectivity of physical devices.

  14. Investigation on empirical estimation of minor tides

    Bosch, Wolfgang; Madzak, Matthias; Hagedorn, Jan; Schuh, Harald; Böhm, Sigrid

    2014-05-01

    In general recent global ocean tide models provide tidal constants for the most dominant semi-diurnal, diurnal, selected shallow water and some long period tides, typically M2, N2, N2 , K2, 2N2, O1 , P1 , Q1 , K1, S1, M4, Mf and Mm. Contributions of minor tidal terms and modulations of the main terms are in general considered by inferring admittance assumptions and nodal corrections. The rather new hydrodynamic model FES2012 extends this list and now provides additional tables for tidal constants for some 18 complementary minor tides. We investigate here if the long time series of precise multi-mission altimeter data (e.g. on the repeated ground tracks of TOPEX/Jason1/Jason2) allows a robust empirical estimation of those minor tides which appear to be (after the major tides listed above) the next dominant tidal waves. Candidate minor tidal waves are M1, J1, σ1, ν2, L2, T2, μ2. Can these partial tides empirically separated from tides with adjacent frequencies (e.g. μ2 versus 2N2 or T2 versus S2)? How do the tidal constant for those minor tides compare with those of the hydrodynamic model FES2012? What are the quantitative differences between applying admittance theory and using the tidal constants derived empirically? These investigations are performed in the context of the SPOT-project, aiming to improve the transfer function from ocean tide angular momentum to Earth rotation parameters, the variations of polar motion and LOD.

    2004-01-01

    Over the past 30 years the importance of vaccines for minor use and minor species has changed for multinational animal health companies. The major reasons for this are being reviewed, with a particular focus on technical, financial and business aspects. Key regulatory obstacles to the development of new products for minor uses and minor species are identified, and examples of vaccines falling into the various categories are provided. A number of proposals are offered with the intention of resolving the medicines availability problem between all the stakeholders involved. Finally, based on the presented scientific and regulatory considerations, ideas are shared as to where the legal and economical framework would need to change to reach a viable solution.

    1986-04-01

    The focus of this investigation was to identify issues central to increasing the involvement of small minority businesses (MBs) in federal or prime contracts with the Department of Energy (DOE), as a foundation for designing a program to assist buyers of contracted goods and services. The approach to determining issues involved interviewing the owners of 15 MBs, representing a range of businesses, and buyers and purchasing officers from three large DOE prime contractors. The interviewees identified issues related to positive working relationships and rated a predetermined set of 27 potential MB-DOE problems regarding their existence and criticalness. The issues identified by MBs were of two broad types. The predominant issues and barriers were associated with their being small businesses. Secondary issues reflected the disadvantaged status of the business (woman and/or minority-owned).

    2009-01-01

    The purpose of this study was to examine the relationships of sexual minority youth and their siblings. The participants were 56 lesbian, gay, bisexual, or transgender individuals ranging in age from 18 to 24 years, who reported information about a total of 107 siblings. Respondents completed a demographic data questionnaire as well as adapted versions of the Sibling Closeness Scale (SCS) and the Sibling Approval of Sexual Behavior Scale (SASBS) to describe their relationship with each of their siblings. Analyses examined birth order and gender in relation to outness to siblings as well as sibling closeness and approval. Results provide information about disclosure of LGBT status to siblings, elements of closeness and acceptance in sibling relationships of sexual minority youth, and the significance of gender and birth order in these sibling relationships.

    The purpose of this research is to project household energy consumption, energy expenditure, and energy expenditure as share of income for five population groups from 1991 to 2009. The approach uses the Minority Energy Assessment Model (MEAM), developed by Argonne National Laboratory for the US Department of Energy`s Office of Minority Economic Impact. The MEAM provides a framework that can be used to forecast regional energy consumption and energy expenditure for majority, black, Hispanic, poor, and nonpoor households. The forecasts of key macroeconomic and energy variables used as exogenous variables in the MEAM were obtained from the Data Resources, Inc., Macromodel and Energy Model. Generally, the projections of household energy consumption, expenditure, and energy expenditure as share of income vary across population groups and census regions.

  19. A Review of Culturally Targeted/Tailored Tobacco Prevention and Cessation Interventions for Minority Adolescents

    2012-01-01

    Aim: Emerging racial/ethnic disparities in tobacco use behaviors and resulting long-term health outcomes highlight the importance of developing culturally tailored/targeted tobacco prevention and cessation interventions. This manuscript describes the efficacy and the components of prevention and cessation interventions developed for minority adolescents. Methods: Thirteen studies focused on culturally tailoring and targeting tobacco prevention/cessation interventions were selected and information on intervention design (type, number of sessions), setting (school or community), theoretical constructs, culture-specific components (surface/deep structures), and treatment outcomes were extracted. Results: Of the 13 studies, 5 focused on prevention, 4 on cessation, and 4 combined prevention and cessation, and most of the studies were primarily school-based, while a few used community locations. Although diverse minority groups were targeted, a majority of the studies (n = 6) worked with Hispanic adolescents. The most common theoretical construct examined was the Social Influence Model (n = 5). The overall findings indicated that culturally tailoring cessation interventions did not appear to improve tobacco quit rates among minority adolescents, but culturally tailored prevention interventions appeared to produce lower tobacco initiation rates among minority adolescents than control conditions. Conclusions: The results of review suggest that there is a critical need to develop better interventions to reduce tobacco use among minority adolescents and that developing a better understanding of cultural issues related to both cessation and initiation of tobacco use among minority populations is a key component of this endeavor.

    Sexual minorities have higher rates of depression and anxiety than their heterosexual counterparts. This elevated risk of psychological distress has generally been hypothesized to be a result of the effects of discrimination including internalized negative beliefs about sexual minorities. However, little research has examined the role of various types of coping in mediating between internalized homophobia and mental health. We tested the direct relationship between internalized homophobia and psychological distress and evaluated general and sexual minority-specific coping strategies as potential mediators using structural equation modeling. Data are from a national sample of 1,099 young adult sexual minority women who were on average 20.86 (SD= 2.12) years old, participating in a study on mental health and substance use. The model demonstrated acceptable fit, χ2 (83) = 402.9, p <.001, CFI=.94, TLI=.92, SRMR= .07, and RMSEA=.06, accounting for 73% of variance in psychological distress. Greater use of maladaptive coping and less use of sexual minority-specific coping were associated with higher psychological distress. Although maladaptive coping mediated the relationship between internalized homophobia and psychological distress, sexual minority-specific coping did not. Our findings support previous studies that have demonstrated the impact of internalized homophobia on psychological distress as well as the role of coping as a protective/risk factor in this relationship.

    Inverted ductal papillomas are rare tumours of minor salivary glands. A case is reported on the lower lip of a 50-year-old man. The tumour showed a characteristic endophytic growth pattern and was composed of bulbous papillary projections of basaloid cells dilating and filling the superficial portion of the excretory duct. Histologically, inverted ductal papillomas resemble the inverted papilloma of the nose and paranasal sinuses, but are completely benign and are not associated with malignant change.

  5. Natural Minor Scale is More Natural to the Brain than Harmonic Minor Scale as Revealed by Magnetoencephalography

    NASA Astrophysics Data System (ADS)

    Ando, Hiromitsu; Nemoto, Iku; Oda, Shoichiro

    Minor mode is known to elicit stronger emotional responses than major mode in the brain. The present work focused on the minor scales and natural and harmonic minor scales were compared in automatic brain responses in an oddball paradigm. The standard stimulus was either the natural or harmonic minor scale, and a deviant stimulus lacked one scale tone of the corresponding complete minor scale. The brain responded to omission of every tone but omission of the tone B flat in the natural minor experiment elicited larger response than that of the other tones. In particular, the response was significantly larger than that to omission of B in the harmonic minor experiment. This result suggested that the brain felt the natural minor scale to be actually more natural than the harmonic minor scale.

    Sexual minority youth (youth who are attracted to the same sex or endorse a gay/lesbian/bisexual identity) report significantly higher rates of depression and suicidality than heterosexual youth. The minority stress hypothesis contends that the stigma and discrimination experienced by sexual minority youth create a hostile social environment that can lead to chronic stress and mental health problems. The present study used longitudinal mediation models to directly test sexual minority-specific victimization as a potential explanatory mechanism of the mental health disparities of sexual minority youth. One hundred ninety-seven adolescents (14-19 years old; 70 % female; 29 % sexual minority) completed measures of sexual minority-specific victimization, depressive symptoms, and suicidality at two time points 6 months apart. Compared to heterosexual youth, sexual minority youth reported higher levels of sexual minority-specific victimization, depressive symptoms, and suicidality. Sexual minority-specific victimization significantly mediated the effect of sexual minority status on depressive symptoms and suicidality. The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.

The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.

    With more and more applications appearing and the technology developing in the Internet, only relying on terminal system can not satisfy the complicated demand of QoS network. Router mechanisms must be participated into protecting responsive flows from the non-responsive. Routers mainly use active queue management mechanism (AQM) to avoid congestion. In the point of interaction between the routers, the paper applies minority game to describe the interaction of the users and observes the affection on the length of average queue. The parameters α, β of ARED being hard to confirm, adaptive RED based on minority game can depict the interactions of main body and amend the parameter α, β of ARED to the best. Adaptive RED based on minority game optimizes ARED and realizes the smoothness of average queue length. At the same time, this paper extends the network simulator plat - NS by adding new elements. Simulation has been implemented and the results show that new algorithm can reach the anticipative objects.

    Background Available data suggest that childhood cancer survivors (CCSs) are comparable to the general population on many lifestyle parameters. However, little is known about minority CCSs. This cross-sectional study describes and compares the body mass index (BMI) and health behaviors of African-American, Hispanic and White survivors to each other and to non-cancer controls. Methods Participants included 452 adult CCS (150 African-American, 152 Hispanic, 150 white) recruited through four childhood cancer treating institutions and 375 ethnically-matched non-cancer controls (125 in each racial/ethnic group) recruited via targeted digit dial. All participants completed a 2-hour in-person interview. Results Survivors and non-cancer controls reported similar health behaviors. Within survivors, smoking and physical activity were similar across racial/ethnic groups. African-American and Hispanic survivors reported lower daily alcohol use than whites, but consumed unhealthy diets and were more likely to be obese. Conclusions This unique study highlights that many minority CCSs exhibit lifestyle profiles that contribute to increased risk for chronic diseases and late effects. Recommendations for behavior changes must consider the social and cultural context in which minority survivors may live. PMID:25564774

    The earth is warming, and it is warming quickly. Epidemiological studies have demonstrated that global warming is correlated with the frequency of pollen-induced respiratory allergy and allergic diseases. There is a body of evidence suggesting that the prevalence of allergic diseases induced by pollens is increasing in developed countries, a trend that is also evident in the Mediterranean area. Because of its mild winters and sunny days with dry summers, the Mediterranean area is different from the areas of central and northern Europe. Classical examples of allergenic pollen-producing plants of the Mediterranean climate include Parietaria, Olea and Cupressaceae. Asia Minor is a Mediterranean region that connects Asia and Europe, and it includes considerable coastal areas. Gramineae pollens are the major cause of seasonal allergic rhinitis in Asia Minor, affecting 1.3-6.4 % of the population, in accordance with other European regions. This article emphasizes the importance of global climate change and anticipated increases in the prevalence and severity of allergic disease in Asia Minor, mediated through worsening air pollution and altered local and regional pollen production, from an otolaryngologic perspective.

  11. Axonal change in minor head injury.

    Anterograde axonal transport of horseradish peroxidase (HRP) in selected cerebral and cerebellar efferents was studied in cats subjected to minor head injury. After trauma, the animals were allowed to survive from one to 24 hours, when they were perfused with aldehydes and processed for the light and electron microscopic visualization of the peroxidase reaction product. By light microscopy, the brain injury elicited an initial intra-axonal peroxidase pooling. With longer post-traumatic survival, HRP pooling increased in size, demonstrated frequent lobulation, and ultimately formed large ball- or club-like swellings which suggested frank axonal separation from the distal axonal segment. Ultrastructural examination revealed that the initial intra-axonal peroxidase pooling was associated with organelle accumulation which occurred without any other form of axonal change or related parenchymal or vascular damage. This accumulation of organelles increased with time and was associated with conspicuous axonal swelling. Ultimately these organelle-laden swellings lost continuity with the distal axonal segment and the axonal swelling was either completely invested by a thin myelin sheath or protruded without myelin investment into the brain parenchyma. This study suggests that axonal change is a consistent feature of minor head injury. Since these axonal changes occurred without any evidence of focal parenchymal or vascular damage, minor brain injury may ultimately disrupt axons without physically shearing or tearing them.

  12. On entropy, financial markets and minority games

    The paper builds upon an earlier statistical analysis of financial time series with Shannon information entropy, published in [L. Molgedey, W. Ebeling, Local order, entropy and predictability of financial time series, European Physical Journal B-Condensed Matter and Complex Systems 15/4 (2000) 733-737]. A novel generic procedure is proposed for making multistep-ahead predictions of time series by building a statistical model of entropy. The approach is first demonstrated on the chaotic Mackey-Glass time series and later applied to Japanese Yen/US dollar intraday currency data. The paper also reinterprets Minority Games [E. Moro, The minority game: An introductory guide, Advances in Condensed Matter and Statistical Physics (2004)] within the context of physical entropy, and uses models derived from minority game theory as a tool for measuring the entropy of a model in response to time series. This entropy conditional upon a model is subsequently used in place of information-theoretic entropy in the proposed multistep prediction algorithm.

    The postembryonic development and caste differentiation patterns of lower termites have been described multiple times in a variety of different species. However, most of these studies focused on gross ontogeny, without carefully describing the maturation of any particular organ or organ system. The few studies that have attempted to correlate caste development and organ differentiation have produced somewhat inconsistent results, especially in the area of eye formation. Therefore, in order to help further elucidate the relationship between eye formation and postembryonic differentiation in lower termites, we studied eye development in the termite, Incisitermes minor (Hagen). Eye formation in I. minor began in the earliest larvae, with only an eye primordium. However, in all later larval stages, characteristic eye structures were observed and were shown to progressively differentiate through larval and nymphal stages. Curiously, pigmentation began with three to eight groups of cells in early larvae and the number of these pigmented groups increased along the developmental time course. Ultimately, a uniformly pigmented eye area was formed by the early nymphal stage. The overall eye area also gradually increased along with normal caste development, but the characteristic lenses seen in a prototypical insect compound eye did not completely form until after the final nymphal stage. Electrophysiological measurements provided clear evidence that eyes were indeed functional at all stages of development where pigment was present. Based upon this data, the eye development pattern in I. minor appeared to follow a divergent pathway from holometabolous insects and an intermediate pathway between typical hemimetabolous eye development and the heterochronic shift observed in other termite species.

    The aim of the study was to investigate the differing epidemiology of hepatitis C-related end-stage liver disease in ethnic minorities in England. We used Hospital Episode Statistics from 1997/98 to 2004/05 to directly age-standardize numbers of episodes and deaths from hepatitis C-related end-stage liver disease in ethnic groups using the white English population as standard and the age-structured population by ethnic group from the 2001 Census. We estimated the odds of having a diagnosis of end-stage liver disease amongst hepatitis C-infected individuals in each ethnic group compared with whites using logistic regression. The main outcome measures were age-standardized morbidity and mortality ratios and morbidity and mortality odds ratios. Standardized ratios (95% confidence interval) for hepatitis C-related end-stage liver disease ranged from 73 (38-140) in Chinese people to 1063 (952-1186) for those from an 'Other' ethnic group. Amongst individuals with a diagnosis of hepatitis C infection, the odds ratios (95% CI) of severe liver disease were 1.42 (1.13-1.79), 1.57 (1.36-1.81), 2.44 (1.85-3.22), 1.73 (1.36-2.19) and 1.83 (1.08-3.10) comparing individuals of Black African, Pakistani, Bangladeshi, Indian and Chinese origin with whites, respectively. Ethnic minority populations in England are more likely than whites to experience an admission or to die from severe liver disease as a result of hepatitis C infection. Ethnic minority populations may have a higher prevalence of hepatitis C or they may experience a poorer prognosis because of differential access to health services, longer duration of infection or the prevalence of co-morbidities.

  15. Energy policy: Comparative effects on minority population groups

    For a number of years, analyses of minority household energy demand have been supported by the United States Department of Energy (DOE), Office of Economic Impact and Diversity (formerly the Office of Minority Economic Impact). The intention of these analyses has been to characterize patterns of energy demand by various demographic, regional and socioeconomic groups and to develop analytical tools to assess the distributive impact of energy prices and policy on these groups. The model supports strategic objectives outlined by the Department of Energy to explicitly recognize and promote equity in state public utility commission decisions and to assess the potential impact of federal and state energy policy on demographically diverse groups as reported in the Department`s Annual Energy Outlook and the upcoming National Energy Policy Plan. The legislation mandating the Office of Economic Impact and Diversity had been premised on the assumption that patterns of energy demand for minority households are different from the population as a whole. Determining the validity of this premise and its potential economic impact on different population groups has been a major objective of these analyses. Consequently, the recripriocal impacts of energy policy on demographic groups and energy consumption and expenditure dynamics on policy formulation and strategy is a central objective of these studies. Residential energy demand research has been substantial in the past twenty years. Insightful and useful research has been done in this area. However, none of this research has addressed the potential differences in the residential energy demand structure among various population groups. Recent work does compare energy and electricity demand elasticities for non-Latino Whites, with the demand elasticities for Latinos and Blacks. This research is particularly important for examination of questions related to the economic welfare implications of national energy policy.

    1. Despite regulatory and case identification efforts, lead exposure continues to pose a major health problem for minority workers. 2. Minority workers are overrepresented in lead industries such as lead smelting, lead storage batteries, lead pigment production and pottery. 3. Preliminary data from recently instituted lead registries in California and Texas suggest that minority workers continue to be overexposed to lead. 4. A federal policy that strengthens enforcement of the OSHA lead standard is needed to reduce lead exposure among minority workers.

  2. Major and minor groove conformations of DNA trimers modified on guanine or adenine by 4-aminobiphenyl: Adenine adducts favor the minor groove

    We have studied the conformational effects of 4-aminobiphenyl modification at C-8 of guanine or adenine on double-stranded DNA trimers. We used sequences with the modified purine at the central base pair and all 16 possible neighboring sequences at the outer pairs. Minimized potential energy calculations were carried out using the molecular mechanics program DUPLEX to survey the conformation space of these adducts, using a total of 1280 starting structures both in the modified guanine series and in the modified adenine series. Conformer families in which the bound 4-aminobiphenyl was located in the DNA major groove, and in the minor groove, were located for both adenine and guanine modification. In the modified guanine series, the major and minor groove families were roughly comparable in energy, and the sequence context determined which was more stable in a particular case. In the modified adenine series, however, the minor groove structure was more that 10 kcal/mol more stable than the major groove for all sequences. As a result, minor groove adducts provided most of the global minima in the adenine-modified series. This result may be relevant to a previous mutagenesis study [Lasko et al. (1988) J. Biol. Chem. 263, 15429-15435] in which the hot spot of most frequent occurrence was located at an adenine, in the sequence GAT. 25 refs., 9 figs., 4 tabs.

    2014-01-01

    The Coping With Discrimination Scale (CDS) shows promise as a self-report measure of strategies for coping with racial discrimination. To assess the psychometric properties of the measure for use with sexual minorities (i.e., gay, lesbian, bisexual, or GLB persons), a nonprobability sample of 371 GLB adults completed the instrument along with several standardized, self-report measures. Confirmatory factor analyses supported the five-factor structure of the original scale with the exclusion of five items. Adequate internal consistency reliability was found. Internalization, drug and alcohol use, and detachment subscales were correlated positively with measures of psychological distress and negatively with a measure of life satisfaction, providing evidence of construct validity. The education/advocacy and resistance subscales were largely unrelated to concurrently administered validation measures, consistent with prior findings. Coping strategy use varied as a function of primary sources of social support. The CDS appears to be a psychometrically sound measure of several discrimination coping strategies for use with sexual minorities.

    The imbalanced nature of some real-world data is one of the current challenges for machine learning researchers. One common approach oversamples the minority class through convex combination of its patterns. We explore the general idea of synthetic oversampling in the feature space induced by a kernel function (as opposed to input space). If the kernel function matches the underlying problem, the classes will be linearly separable and synthetically generated patterns will lie on the minority class region. Since the feature space is not directly accessible, we use the empirical feature space (EFS) (a Euclidean space isomorphic to the feature space) for oversampling purposes. The proposed method is framed in the context of support vector machines, where the imbalanced data sets can pose a serious hindrance. The idea is investigated in three scenarios: 1) oversampling in the full and reduced-rank EFSs; 2) a kernel learning technique maximizing the data class separation to study the influence of the feature space structure (implicitly defined by the kernel function); and 3) a unified framework for preferential oversampling that spans some of the previous approaches in the literature. We support our investigation with extensive experiments over 50 imbalanced data sets.

    This article reports a study of the function and composition of social support networks among diverse lesbian, gay, and bisexual (LGB) men and women (n = 396) in comparison to their heterosexual peers (n = 128). Data were collected using a structured social support network matrix in a community sample recruited in New York City. Our findings show that gay and bisexual men may rely on "chosen families" more than lesbian and bisexual women. Both heterosexuals and LGBs relied less on family and more on other people (e.g., friends, coworkers) for everyday social support (e.g., recreational and social activities, talking about problems). Providers of everyday social support were most often of the same sexual orientation and race/ethnicity as participants. In seeking major support (e.g., borrowing large sums of money), heterosexual men and women along with lesbian and bisexual women relied primarily on their families, but gay and bisexual men relied primarily on other LGB individuals. Racial/ethnic minority LGBs relied on LGB similar others at the same rate as did White LGBs but, notably, racial/ethnic minority LGBs reported receiving fewer dimensions of support.

  7. Physical activity efficacy and effectiveness among older adults and minorities.

    1997-07-01

    The objective of this study was to consider efficacy and effectiveness of physical activity for the prevention and management of NIDDM among minorities and older adults of the U.S. Relevant population trends and projections are discussed, followed by a review of the efficacy of physical activity based on theoretical, prospective cohort, and intervention studies. With few empirical studies available, the assessment of effectiveness is largely theoretical and focuses on potentially important issues for future studies among older adults and minorities. Efficacy studies have shown that moderate-intensity physical activity is associated with a one- to two-thirds lower incidence of NIDDM over 4-14 years and 15-20% lower glycosylated hemoglobin over 3-4 months among people with NIDDM. With physical inactivity prevalence at 60-70%, much work remains to be done to improve physical activity effectiveness. In the most vulnerable populations, physician referral and community involvement structured around stage of change and self-efficacy theories are suggested as the most promising approaches to promoting physical activity adoption and maintenance. Effectiveness or demonstration studies that test and build on stage of change, self-efficacy, and other concepts of physical activity promotion and outcomes would likely prove to be highly valuable investments for public health.

  5. Algorithmic complexity in the minority game

    PubMed

    Mansilla

    2000-10-01

    In this paper, we present our approach for the study of the complexity of Minority Game using tools from thermodynamics and statistical physics. Previous attempts were based on the behavior of volatility, an observable of the financial markets. Our approach focuses on some properties of the binary stream of outcomes of the game. Physical complexity, a magnitude rooted in Kolmogorov-Chaitin theory, allows us to explain some properties of collective behavior of the agents. Mutual information function, a measure related to Shannon's information entropy, was useful to observe a kind of phase transition when applied to the binary string of the whole history of the game.

    1987-06-26

    The author reviews the legal trend in the United States during the last 25 years toward allowing adolescents greater freedom to make decisions regarding their health care. She discusses courts' use of the "mature minor" rule; state statutes permitting treatment of venereal disease and drug and alcohol abuse without parental knowledge; constitutional rights of adolescents to contraception at federally funded facilities; state requirements for parental or judicial involvement in adolescents' abortion decisions; and treatment refusal of elective as opposed to lifesaving treatment. Holder suggests that physicians consult their state or county medical societies for the specific laws that apply where they practice.

  7. Minorities in Nursing Education: Using Smartphones.

    PubMed

    Day-Black, Crystal

    2015-01-01

    The use of Smartphones in teaching and learning is transforming academia and affords a shift in paradigm for Historically Black Universities and Colleges (HBCUs) nurse programs for the 21st century. Smartphone use in academic settings has gained popularity among college students. For minority and low-income students, this handheld device may be the only source to real-time Internet-accessible information, and in anchoring social, vocational, and academic habits. Nursing faculty acceptance of smartphones in the classroom assists in clinical and simulation learning experiences. These experiences are keys to integration of successful smartphone initiatives in HBCU nursing programs. PMID:26665502

    There are about 15 African-American professional astronomers in the United States. Not 15 percent, fifteen. Latinos and Native Americans are similarly underrepresented. Those who make it not only must run the usual gauntlet of school, college, graduate school, and the job market; they must jump extra hurdles that can include poverty, discrimination, isolation, expectations of failure, and the burden of "representing" their ethnic group to their profession and their profession to their ethnic group. Over the past two decades, astronomers have worked to improve women's representation in their profession. What can we do to support American minority groups?

    Guallart Doménech, F; Molina Mira, A; González Martínez, M A; Pons Rocher, F; Mompó Romero, L; Serrano Badía, E

    1994-01-01

    Adenomatoid hyperplasia of minor salivary glands in an uncommon clinicopathologic entity, first reported, in 1971, by Giansanti and cols. The condition mimics a neoplasm because of its swelling, but the histologic picture agrees with that of normal appearing salivary gland tissue. The interest of this entity is that although benign pseudotumoral lesion, it can be clinically confused with benign or malignant tumors and even, through fine needle aspiration cytology, with low grade mucoepidermoid tumors. We present one case of this condition arising in the soft palate in a patient with unilateral serous otitis media. A review of the published literature on the subject is done.

  14. Surfing the "model minority" wave of success: how the school context shapes distinct experiences among Vietnamese youth.

    PubMed

    Conchas, Gilberto Q; Pérez, Cristina C

    2003-01-01

    Vietnamese students must contend with the burden of the myth of being a model minority. As a result of adults' high expectations of them, Vietnamese youth receive structural and ideological advantages over other nonwhite racial groups. Further, the students themselves reinforce the model minority image as they attempt to attain educational mobility. The authors examine the role of two distinct school contexts within the same school that shape the academic outcomes of Vietnamese students contending with the pressures of being considered members of the model minority.

    2010-01-01

    This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

    Queensborough Community College (QCC) and Medgar Evers College (MEC) of the City University of New York have been actively involved in recruiting primarily minority students to the Geosciences by involving students in research and by incorporating innovative and proven pedagogical methods into the classroom. Students at both colleges have been actively involved in doing research in Space and Earth Science. Students work during the summer under the mentorship of CUNY faculty conducting experiments and analyzing data. At the end of the summer students present findings at various science meetings. In the lecture room, the method of instruction was modified to emphasize active learning. Educational materials and pedagogical methods developed at QCC and other 4 year colleges was introduced to the predominantly minority student body at QCC and MEC. Many of these students did poorly at pre-college schools where lecture based learning is the chief method of instruction. It is not unexpected that many of them are having difficulty if the method of instruction has not changed at the postsecondary level. The intent of introducing active learning was to have students develop an appreciation of science, and have an increased understanding of relevant scientific principles. As a result of these activities student scores increased as compared to student scores in a more affluent college. Students also demonstrated increased conceptual understanding of the material, had higher self- efficacy scores, and seemed to enjoy the class better. Lower scoring students demonstrated the greatest benefit, while the better students had little (or no) changes.

  19. Major and minor salivary gland tumors.

    Malignant salivary gland tumors are rare. The most common tumor site is the parotid. Aetiologic factors are not clear. Nutrition may be a risk factor, as well as irradiation or a long-standing histologically benign tumor that occurs at youth. Painless swelling of a salivary gland should always be considered as suspicious, especially if no sign of inflammation is present. Signs and symptoms related to major salivary gland tumors differ from those concerning minor salivary gland tumors, as they depend on the different location of the salivary gland. Surgical excision represents the standard option in the treatment of resectable tumors of both major and minor salivary glands. Neutron, heavy ions or proton radiotherapy may be a treatment option for inoperable locoregional disease. Surgery, irradiation or re-irradiation are treatment options for local relapse, whereas radical neck dissection is indicated for regional relapses. Metastatic disease may be either treated with radiotherapy or palliative chemotherapy, depending on the site of metastases. For highly selected patients the employment of anti-androgen therapy is indicated.

    Background Equity in health is a pressing concern and reaching disadvantaged populations is necessary to close the inequity gap. To date, the discourse has predominately focussed on reaching the poor. At the same time and in addition to wealth, other structural determinants that influence health outcomes exist, one of which is ethnicity. Inequities based on group belongings are recognised as ‘horizontal’, as opposed to the more commonly used notion of ‘vertical’ inequity based on individual characteristics. Objective The aim of the present review is to highlight ethnicity as a source of horizontal inequity in health and to expose mechanisms that cause and maintain this inequity in Vietnam. Design Through a systematic search of available academic and grey literature, 49 publications were selected for review. Information was extracted on: a) quantitative measures of health inequities based on ethnicity and b) qualitative descriptions explaining potential reasons for ethnicity-based health inequities. Results Five main areas were identified: health-care-seeking and utilization, maternal and child health, nutrition, infectious diseases, and oral health and hygiene. Evidence suggests the presence of severe health inequity in health along ethnic lines in all these areas. Research evidence also offers explanations derived from both external and internal group dynamics to this inequity. It is reported that government policies and programs appear to be lacking in culturally adaptation and sensitivity, and examples of bad attitudes and discrimination from health staff toward minority persons were identified. In addition, traditions and patriarchal structures within ethnic minority groups were seen to contribute to the maintenance of harmful health behaviors within these groups. Conclusion Better understandings of the scope and pathways of horizontal inequities are required to address ethnic inequities in health. Awareness of ethnicity as a determinant of health, not

    According to China's 1990 census, the ethnic minority population increased by 35.5% from the 1982 census, 23 percentage points higher than the Han nationality. Among 55 ethnic minorities, 16 had growth rates of over 50% between 1982 and 1990. The Korean ethnic minority had the lowest growth rate, which was only 8.73%. The high growth rate of the ethnic minority population was due to the high level of natural increase and policy factors. With the changing policies toward ethnic minorities, preferential treatment has been give to the them in education, employment, career promotion, and childbearing quota. These policies stimulated switching from the Han nationality to the minority status. 50-60% of growth in the minority population between the 2 censuses has been attributed to the status switching. The per capita GNP in the minority administrative areas was 54.9% lower than in Han areas in 1980. It became 69% lower in 1988. Excessive growth of the ethnic minority population hindered education attainment and economic and resources development. Some ethnic minorities have an illiteracy rate of over 90% and an infant mortality rate of 171/1000. The ecological environment in certain minority areas is deteriorating due to extensive tree-felling and primitive farming methods. In contrast, the Korean minority developed its education program earlier on. Its total fertility rate has been around 1.4 since 1974 and it is gradually changing into a stationary population. Currently, no Korean National counties or townships are below the poverty line. The prevalence of disability is 3.5% in the Korean population, the lowest of all the ethnic groups. It is important to focus population programs among the ethnic minorities to increase their health and educational status. Promoting family planning programs, strictly enforcing the criteria for switching to minority status or setting deadlines to preference treatment eligibility for those who switched status could be possible policies

  2. Predictive binding geometry of ligands to DNA minor groove: isohelicity and hydrogen-bonding pattern.

    2014-01-01

    The interaction of drugs and dyes with nucleic acids, particularly when binding to DNA minor groove occurs, has increasing importance in biomedical sciences. This is due to the resulting biological activity and to the possibility of recognizing AT and GC base pairs. In such cases, DNA binding can be predicted if appropriate helical and hydrogen-bonding parameters are deduced from DNA models, and a simplified geometrical rule in the form of a stencil is then applied on computer-drawn molecules of interest. Relevant structure parameter values for minor groove binders are the length (4.6 < L < 5.4 Å) and angle (152 < σ < 156.5°) between three consecutive units, measured at the level of hydrogen donor or acceptor groups. Application of the stencil shows that predictive methods can aid in the design of new compounds, by checking the possible binding of isohelical sequence-specific ligands along the DNA minor groove.

    Premise of the study: Polymorphic microsatellite markers were developed in Vinca minor (Apocynaceae) to evaluate the level of clonality, population structure, and genetic diversity of the species within its native and introduced range. Methods and Results: A total of 1371 microsatellites were found in 43,565 reads from 454 pyrosequencing of genomic V. minor DNA. Additional microsatellite loci were mined from publicly available cDNA sequences. After several rounds of screening, 18 primer pairs flanking di-, tri-, or tetranucleotide repeats were identified that revealed high levels of genetic diversity in two native Italian populations, with two to 11 alleles per locus. Clonal growth predominated in two populations from the introduced range in Germany. Five loci successfully cross-amplified in three additional Vinca species. Conclusions: The novel polymorphic microsatellite markers are promising tools for studying clonality and population genetics of V. minor and for assessing the historical origin of Central European populations.

    This study examined risk and protective outcomes by comparing homeless sexual minority youths to heterosexual homeless youths regarding family, peer behaviors, school, mental health (suicide risk and depression), stigma, discrimination, substance use, and sexual risk behaviors. Structured interviews (N = 147) were conducted with individuals ages 16-24 at three drop-in programs serving homeless youths in Toronto. Bivariate analyses indicated statistically significant differences between homeless sexual minorities (n=66) and their heterosexual counterparts (n=81) regarding all variables: family, peer behaviors, stigma, discrimination, mental health, substance use and sexual risk behaviors with the exception of school belonging. Specifically, homeless sexual minority youths fared more poorly (e.g. lower satisfaction with family communication, experienced more stigma, used more drugs and alcohol) than their heterosexual counterparts. Improving family communication may be a worthwhile intervention if the youths are still in contact with their families. Future research should focus on victimization in the context of multiple systems.

    The Cleveland State University Minority Engineering Program Pipeline consist of programs which foster engineering career awareness, academic enrichment, and professional development for historically underrepresented minority studies. The programs involved are the Access to Careers in Engineering (ACE) Program for high school pre-engineering students: the LINK Program for undergraduate students pursuing degree which include engineering; and the PEP (Pre-calculus Enrichment Program) and EPIC (Enrichment Program in Calculus) mathematics programs for undergraduate academic enrichment. The pipeline is such that high school graduates from the ACE Program who enroll at Cleveland State University in pursuit of engineering degrees are admitted to the LINK Program for undergraduate level support. LINK Program students are among the minority participants who receive mathematics enrichment through the PEP and EPIC Programs for successful completion of their engineering required math courses. THese programs are interdependent and share the goal of preparing minority students for engineering careers by enabling them to achieve academically and obtain college degree and career related experience.

    Black sexual minority women are triply marginalized due to their race, gender, and sexual orientation. We compared three dimensions of discrimination—frequency (regularity of occurrences), scope (number of types of discriminatory acts experienced), and number of bases (number of social statuses to which discrimination was attributed)—and self-reported mental health (depressive symptoms, psychological well-being, and social well-being) between 64 Black sexual minority women and each of two groups sharing two of three marginalized statuses: (a) 67 White sexual minority women and (b) 67 Black sexual minority men. Black sexual minority women reported greater discrimination frequency, scope, and number of bases and poorer psychological and social well-being than White sexual minority women and more discrimination bases, a higher level of depressive symptoms, and poorer social well-being than Black sexual minority men. We then tested and contrasted dimensions of discrimination as mediators between social status (race or gender) and mental health outcomes. Discrimination frequency and scope mediated the association between race and mental health, with a stronger effect via frequency among sexual minority women. Number of discrimination bases mediated the association between gender and mental health among Black sexual minorities. Future research and clinical practice would benefit from considering Black sexual minority women's mental health in a multidimensional minority stress context. PMID:26424904

    The underrepresentation in epidemiology of members of racial/ethnic minority groups is greater than in medicine and health fields in general. Using printed recruitment materials, we evaluated the impression that epidemiology programs might make on prospective minority students. Mainstream recruitment materials were solicited from all identifiable U.S. epidemiology programs (n = 70) by requesting copies of typical mailings to prospective students. Of 51 respondents, 46 sent materials that could be analyzed by tabulating and evaluating minority-related content in text and pictures. Materials reflected a generally low-key approach to epidemiology student recruitment. Most minority-related text referred to affirmative action or financial aid and was at the school level rather than specific to the epidemiology programs. Few minority-related epidemiology course titles or research interests were identified. We recommend including more information about epidemiology and its relevance to minority health in mainstream recruitment materials as one possible strategy for increasing the number of minority applicants.

    2001-12-01

    Since 1971, the American Geological Institute (AGI) Minority Participation Program (MPP) has supported scholarships for underrepresented minorities in the geosciences at the undergraduate and graduate levels. Some of our MPP scholars have gone on to hugely successful careers in the geosciences. MPP scholars include corporate leaders, university professors, a NASA scientist-astronaut and a National Science Foundation (NSF) CAREER awardee. Yet as ethnic minorities continue to be underrepresented in the geosciences, AGI plans to expand its efforts beyond its traditional undergraduate and graduate scholarships to include diversity programs for secondary school geoscience teacher internships, undergraduate research travel support, and doctoral research fellowships. Funding for the MPP has come from multiple sources, including industry, scientific societies, individuals, and during the last 10 years, the NSF. College-level students apply for the MPP awards or award renewals, and the MPP Advisory Committee selects scholarship recipients based upon student academic performance, financial need, and potential for success as a geoscience professional. Mentoring is a long-standing hallmark of the AGI MPP. Every AGI MPP scholar is assigned a professional geoscientist as a mentor. The mentor is responsible for regular personal contacts with MPP scholars. The MPP Advisory Committee aims to match the profession of the mentor with the scholar's academic interest. Throughout the year, mentors and scholars communicate about possible opportunities in the geosciences such as internships, participation in symposia, professional society meetings, and job openings. Mentors have also been active in helping younger students cope with the major changes involved in relocating to a new region of the country or a new college culture. We believe that AGI is well-positioned to advance diversity in the geosciences through its unique standing as the major professional organization in the

  17. Probing Minor Groove Hydrogen Bonding Interactions between RB69 DNA Polymerase and DNA

    Minor groove hydrogen bonding (HB) interactions between DNA polymerases (pols) and N3 of purines or O2 of pyrimidines have been proposed to be essential for DNA synthesis from results obtained using various nucleoside analogues lacking the N3 or O2 contacts that interfered with primer extension. Because there has been no direct structural evidence to support this proposal, we decided to evaluate the contribution of minor groove HB interactions with family B pols. We have used RB69 DNA pol and 3-deaza-2'-deoxyadenosine (3DA), an analogue of 2-deoxyadenosine, which has the same HB pattern opposite T but with N3 replaced with a carbon atom. We then determined pre-steady-state kinetic parameters for the insertion of dAMP opposite dT using primer/templates (P/T)-containing 3DA. We also determined three structures of ternary complexes with 3DA at various positions in the duplex DNA substrate. We found that the incorporation efficiency of dAMP opposite dT decreased 10{sup 2}-10{sup 3}-fold even when only one minor groove HB interaction was missing. Our structures show that the HB pattern and base pair geometry of 3DA/dT is exactly the same as those of dA/dT, which makes 3DA an optimal analogue for probing minor groove HB interactions between a DNA polymerase and a nucleobase. In addition, our structures provide a rationale for the observed 10{sup 2}-10{sup 3}-fold decrease in the rate of nucleotide incorporation. The minor groove HB interactions between position n-2 of the primer strand and RB69pol fix the rotomer conformations of the K706 and D621 side chains, as well as the position of metal ion A and its coordinating ligands, so that they are in the optinal orientation for DNA synthesis.

    Members of the Joint Working Group on Improving Underrepresented Minorities (URMs) Persistence in Science, Technology, Engineering, and Mathematics (STEM)-convened by the National Institute of General Medical Sciences and the Howard Hughes Medical Institute-review current data and propose deliberation about why the academic "pathways" leak more for URM than white or Asian STEM students. They suggest expanding to include a stronger focus on the institutional barriers that need to be removed and the types of interventions that "lift" students' interests, commitment, and ability to persist in STEM fields. Using Kurt Lewin's planned approach to change, the committee describes five recommendations to increase URM persistence in STEM at the undergraduate level. These recommendations capitalize on known successes, recognize the need for accountability, and are framed to facilitate greater progress in the future. The impact of these recommendations rests upon enacting the first recommendation: to track successes and failures at the institutional level and collect data that help explain the existing trends.

    2016-01-01

    The number of unaccompanied immigrant minors (UIMs) from Central America significantly increased in 2014. Nearly 50,000 children from El Salvador, Guatemala, and Honduras crossed the United States-Mexico border in 2014, compared with 3,933 in 2011. Few resources exist to guide pediatric nurse practitioners (PNPs) in their care of UIM. The multifactorial reasons behind migration and the state of children's health in Central America provide insight into the needs of UIMs. Guidelines for similar groups such as foreign-born children and refugees offer direction for the health care considerations of UIMs. This article provides demographic information on UIMs, highlights the unique and challenging medical and mental health issues facing UIMs, and discusses the role of the PNP. A UIM's initial visit with a PNP serves as an opportunity to build trust through culturally competent, trauma-informed care, provide preventive care, assess for unmet health needs, and screen for mental health conditions.

    An unexpected change in winds at 4-5 km MSL caused airblast ducting and focusing on Carrizozo, NM, 60 km east from MINOR SCALE. In result, this 4.8-kt ANFO (ammonium nitrate-fuel oil) explosion test, rattled the town with 300 Pa (0.0435 psi) overpressure, according to the microbarograph records. Four large (8 x 10 ft) store windows are broken. Weather data which were collected during this event show that conditions changed near shot time, as needed to explain this result. It appears that the variability of winds over the mountains region around WSMR is appreciably larger than over flatter terrain, so that airblast propagation predictions are subject to significant error. Microbarographs are essential in surrounding communities, to document the explosion airblast strength when unexpectedly enhanced blasts occur. The provided empirical model for estimating window damage from expected overpressure appeared to work well. As expected, large windows were the first to fail from the blast.
