    Full text: In 1973, a photoperiod-sensitive genic male-sterile plant was discovered in Nongken 58. It is male sterile under long day conditions and fertile under short day conditions. Under the natural photoperiod in Wuhan, plants heading before September 2 are male sterile, showing typical pollen abortion. The fertility is gradually restored after September 2. About 50% of pollen grains are normal after September 6. F 1 using 30 different varieties was fertile regardless of daylength, F 2 segregated into 3 fertile: 1 sterile types under long day condition in some crosses, less clearly in other crosses. It is concluded that photoperiod depending male sterility is monogenic recessive inherited with some influence of modifier genes. Any normal variety can be used as restorer, therefore strong heterosis combinations can easily be bred. (author)

    There is still limited quantitative understanding of how environmental factors affect sterility of Environment-conditioned genic male sterility (EGMS) lines. A model was developed for this purpose and tested based on experimental data from Ndiaye (Senegal) in 2013-2015. For the two EGMS lines tested here, it was not clear if one or more recessive gene(s) were causing male sterility. This was tested by studying sterility segregation of the F2 populations. Daylength (photoperiod) and minimum temperatures during the period from panicle initiation to flowering had significant effects on male sterility. Results clearly showed that only one recessive gene was involved in causing male sterility. The model was applied to determine the set of sowing dates of two different EGMS lines such that both would flower at the same time the pollen would be completely sterile. In the same time the local popular variety (Sahel 108, the male pollen donor) being sufficiently fertile to produce the hybrid seeds. The model was applied to investigate the viability of the two line breeding system in the same location with climate change (+2oC) and in two other potential locations: in M'Be in Ivory Coast and in the Nile delta in Egypt. Apart from giving new insights in the relation between environment and EGMS, this study shows that these insights can be used to assess safe sowing windows and assess the suitability of sterility and fertility period of different environments for a two line hybrid rice production system.

    Full Text Available Cytoplasm has substantial genetic effects on progeny and is important for yield improvement in rice breeding. Studies on the cytoplasmic effects of cytoplasmic male sterility (CMS show that most types of CMS have negative effects on yield-related traits and that these negative effects vary among CMS. Some types of genic male sterility (GMS, including photo-thermo sensitive male sterility (PTMS, have been widely used in rice breeding, but the cytoplasmic effects of GMS remain unknown. Here, we identified a GMS mutant line, h2s, which exhibited small, white anthers and failed to produce mature pollen. Unlike CMS, the h2s had significant positive cytoplasmic effects on the seed set rate, weight per panicle, yield, and general combining ability (GCA for plant height, seed set rate, weight per panicle, and yield. These effects indicated that h2s cytoplasm may show promise for the improvement of rice yield. Genetic analysis suggested that the phenotype of h2s was controlled by a single recessive locus. We mapped h2s to a 152 kb region on chromosome 6, where 22 candidate genes were predicted. None of the 22 genes had previously been reported to be responsible for the phenotypes of h2s. Sequencing analysis showed a 12 bp deletion in the sixth exon of Loc_Os06g40550 in h2s in comparison to wild type, suggesting that Loc_Os06g40550 is the best candidate gene. These results lay a strong foundation for cloning of the H2S gene to elucidate the molecular mechanism of male reproduction.

    Full Text Available Although cotton genic male sterility (GMS plays an important role in the utilization of hybrid vigor, its precise molecular mechanism remains unclear. To characterize the molecular events of pollen abortion, transcriptome analysis, combined with histological observations, was conducted in the cotton GMS line, Yu98-8A. A total of 2,412 genes were identified as significant differentially expressed genes (DEGs before and during the critical pollen abortion stages. Bioinformatics and biochemical analysis showed that the DEGs mainly associated with sugars and starch metabolism, oxidative phosphorylation, and plant endogenous hormones play a critical and complicated role in pollen abortion. These findings extend a better understanding of the molecular events involved in the regulation of pollen abortion in genic male sterile cotton, which may provide a foundation for further research studies on cotton heterosis breeding.

    The genomic region cosegregating with the genic male-sterile ms 1 gene of Capsicum annuum L. was delimited to a region of 869.9 kb on chromosome 5 through fine mapping analysis. A strong candidate gene, CA05g06780, a homolog of the Arabidopsis MALE STERILITY 1 gene that controls pollen development, was identified in this region. Genic male sterility caused by the ms 1 gene has been used for the economically efficient production of massive hybrid seeds in paprika (Capsicum annuum L.), a colored bell-type sweet pepper. Previously, a CAPS marker, PmsM1-CAPS, located about 2-3 cM from the ms 1 locus, was reported. In this study, we constructed a fine map near the ms 1 locus using high-resolution melting (HRM) markers in an F 2 population consisting of 1118 individual plants, which segregated into 867 male-fertile and 251 male-sterile plants. A total of 12 HRM markers linked to the ms 1 locus were developed from 53 primer sets targeting intraspecific SNPs derived by comparing genome-wide sequences obtained by next-generation resequencing analysis. Using this approach, we narrowed down the region cosegregating with the ms 1 gene to 869.9 kb of sequence. Gene prediction analysis revealed 11 open reading frames in this region. A strong candidate gene, CA05g06780, was identified; this gene is a homolog of the Arabidopsis MALE STERILITY 1 (MS1) gene, which encodes a PHD-type transcription factor that regulates pollen and tapetum development. Sequence comparison analysis suggested that the CA05g06780 gene is the strongest candidate for the ms 1 gene of paprika. To summarize, we developed a cosegregated marker, 32187928-HRM, for marker-assisted selection and identified a strong candidate for the ms 1 gene.

  7. Genic control of honey bee dance language dialect.

    1995-10-01

    Behavioural genetic analysis of honey bee dance language shows simple Mendelian genic control over certain dance dialect differences. Worker honey bees of one parent colony (yellow) changed from round to transition dances for foraging distances of 20 m and from transition to waggle dances at 40 m. Worker bees of the other parent colony (black) made these shifts at 30 m and 90 m, respectively. F1 colonies behaved identically to their yellow parent, suggesting dominance. Progeny of backcrossing between the F1 generation and the putative recessive black parent assorted to four classes, indicating that the dialect differences studied are regulated by genes at two unlinked loci, each having two alleles. Honey bee dance communication is complex and highly integrated behaviour. Nonetheless, analysis of a small element of this behaviour, variation in response to distance, suggests that dance communication is regulated by subsets consisting of simple genic systems.

    Thermosensitive genic male sterile (TGMS) lines and photoperiod-sensitive genic male sterile (PGMS) lines have been successfully used in hybridization to improve rice yields. However, the molecular mechanisms underlying male sterility transitions in most PGMS/TGMS rice lines are unclear. In the recently developed TGMS-Co27 line, the male sterility is based on co-suppression of a UDP-glucose pyrophosphorylase gene (Ugp1), but further study is needed to fully elucidate the molecular mechanisms involved. Microarray-based transcriptome profiling of TGMS-Co27 and wild-type Hejiang 19 (H1493) plants grown at high and low temperatures revealed that 15462 probe sets representing 8303 genes were differentially expressed in the two lines, under the two conditions, or both. Environmental factors strongly affected global gene expression. Some genes important for pollen development were strongly repressed in TGMS-Co27 at high temperature. More significantly, series-cluster analysis of differentially expressed genes (DEGs) between TGMS-Co27 plants grown under the two conditions showed that low temperature induced the expression of a gene cluster. This cluster was found to be essential for sterility transition. It includes many meiosis stage-related genes that are probably important for thermosensitive male sterility in TGMS-Co27, inter alia: Arg/Ser-rich domain (RS)-containing zinc finger proteins, polypyrimidine tract-binding proteins (PTBs), DEAD/DEAH box RNA helicases, ZOS (C2H2 zinc finger proteins of Oryza sativa), at least one polyadenylate-binding protein and some other RNA recognition motif (RRM) domain-containing proteins involved in post-transcriptional processes, eukaryotic initiation factor 5B (eIF5B), ribosomal proteins (L37, L1p/L10e, L27 and L24), aminoacyl-tRNA synthetases (ARSs), eukaryotic elongation factor Tu (eEF-Tu) and a peptide chain release factor protein involved in translation. The differential expression of 12 DEGs that are important for pollen

    At the Agricultural Genetics Institute (AGI), Hanoi, Vietnam, a number of thermo-sensitive genic male sterility (TGMS) homozygous rice lines have been developed by means of experimental mutagenesis followed by anther culture techniques. One of them (TGMS-1 indica mutant line) was used in this research. The critical temperature (at the period from pollen mother cell formation to the beginning of meiotic division) for TGMS-1 sterility was 24-25degC, below which the plants were fertile and above which the plants became sterile. Segregation analysis showed that the TGMS trait of the TGMS-1 mutant line was controlled by a single recessive gene. An F{sub 2} mapping population from a cross between TGMS-1 mutant line and CH1 (a fertile indica line) was developed for tagging and mapping the TGMS gene. From survey of 200 AFLP primer combinations in a bulked segregant analysis, 4 AFLP markers (E2/M5-200, E3/M16-400, E5/M12-600 and E5/M12-200) linked to TGMS-1 gene were identified and cloned. All except E2/M5-200 were found to be low-copy number sequences. The marker E5/M12-600 showed polymorphism in RFLP analysis and was closely linked to the TGMS gene at a distance of 3.3cM. This marker was subsequently mapped on chromosome 2 using doubled-haploid mapping populations derived from the crosses IR64xAzucena and CT9993xIR62666. Linkage of microsatellite marker RM27 with the TGMS gene further confirmed its location on chromosome 2. The closest marker, E5/M12-600, was sequenced so that a PCR marker can be developed for the use in marker-assisted breeding. The application of TGMS genes to the commercial two-line hybrid rice breeding system was discussed. (author)

    A new rice breeding system has been developed, making use of genic male sterility to utilize diverse breeding materials and to promote genetic recombination. In this system, recurrent selection technique and introgressive hybridization were used to increase the frequencies of producing desired genotypes and to improve the population in succession. To promote genetic recombination by the recurrent selection technique, intermating within the population is necessary, and to introduce useful germ plasms by the introgressive hybridization, back crossing with new genetic material is necessary. These can be done efficiently by using the recessive alleles for male sterility, and the representative models for thisF type of breeding were presented. (Kaihara, S.)

    Full Text Available The broad-spectrum blast resistance gene Pi-1, from donor line BL122, was introduced into a thermo-sensitive genic male sterile rice line GD-8S, which possessed good grain quality but high susceptibility to rice blast, by using backcross breeding and molecular marker-assisted selection. Five elite improved male sterile lines, RGD8S-1, RGD8S-2, RGD8S-3, RGD8S-4 and RGD8S-5, were selected based on the results of molecular marker analysis, spikelet sterility, recovery rate of genetic background and agronomic traits. Thirty-three representative blast isolates collected from Guangdong Province, China were used to inoculate the improved lines and the original line GD-8S artificially. The resistance frequencies of the improved lines ranged from 76.47% to 100%, much higher than that of the original line GD-8S (9.09%. On the agronomic characters, there were no significant differences between the improved lines and GD-8S except for flag leaf length and panicle number per plant. The improved lines could be used for breeding hybrid rice with high blast resistance.

    Photoperiod-sensitive genic male-sterile (PSGMS) rice (Oryza sativa L.), a natural mutant found in the rice cultivar Nongken 58, is very useful for the development of hybrid rice cultivars. Despite its widespread use in breeding programs, the initial stage of the abortive development of PSGMS rice and the possible cytological mechanisms of pollen abortion have not been determined. In the present study, a systematic cytological comparison of the anther development of PSGMS rice with its normal fertile counterpart is conducted. The results show that pollen abortion in PSGMS rice first occurs before the pollen mother cell (PMC) stage, and continues during the entire process of pollen development until pollen degradation. The abortive process was closely associated with the abnormal behavior of the tapetum. Although tapetum degeneration in PSGMS rice initiates already at the PMC stage, it proceeds slowly and does not complete until the breakdown of the pollen. Such cytological observations were supported by the results of the TUNEL (TdT-mediated dUTP Nick End Labeling) assay, which detects DNA fragmentation resulting from programmed cell death (PCD), indicating that the premature tapetum degeneration is in the process of PCD.

    Full Text Available To identify genes associated with genic male sterility (GMS that could be useful for hybrid breeding in Chinese cabbage (Brassicarapa ssp. pekinensis, floral bud transcriptome analysis was carried out using a B. rapa microarray with 300,000 probes (Br300K. Among 47,548 clones deposited on a Br300K microarray with seven probes of 60 nt length within the 3' 150 bp region, a total of 10,622 genes were differentially expressed between fertile and sterile floral buds; 4,774 and 5,848 genes were up-regulated over 2-fold in fertile and sterile buds, respectively. However, the expression of 1,413 and 199 genes showed fertile and sterile bud-specific features, respectively. Genes expressed specifically in fertile buds, possibly GMS-related genes, included homologs of several Arabidopsis male sterility-related genes, genes associated with the cell wall and synthesis of its surface proteins, pollen wall and coat components, signaling components, and nutrient supplies. However, most early genes for pollen development, genes for primexine and callose formation, and genes for pollen maturation and anther dehiscence showed no difference in expression between fertile and sterile buds. Some of the known genes associated with Arabidopsis pollen development showed similar expression patterns to those seen in this study, while others did not. BrbHLH89 and BrMYP99 are putative GMS genes. Additionally, 17 novel genes identified only in B. rapa were specifically and highly expressed only in fertile buds, implying the possible involvement in male fertility. All data suggest that Chinese cabbage GMS might be controlled by genes acting in post-meiotic tapetal development that are different from those known to be associated with Arabidopsis male sterility.

    A review on photoperiod and temperature-sensitive genic male sterility in rice. Male sterility in plants, facilitating the development of hybrid crops, has made great contribution to crop productivity worldwide. Environment-sensitive genic male sterility (EGMS), including photoperiod-sensitive genic male sterility (PGMS) and temperature-sensitive genic male sterility (TGMS), has provided a special class of germplasms for the breeding of "two-line" hybrids in several crops. In rice, the finding of the PGMS NK58S mutant in 1973 started the journey of research and breeding of two-line hybrids. Genetic and molecular characterization of these germplasms demonstrated diverse genes and molecular mechanisms of male sterility regulation. Two loci identified from NK58S, PMS1 and PMS3, both encode long noncoding RNAs. A major TGMS locus, TMS5, found in the TGMS line Annong S-1, encodes an RNase Z. A reverse PGMS mutant carbon starved anther encodes an R2R3 MYB transcription factor. Breeding efforts in the last three decades have resulted in hundreds of EGMS lines and two-line hybrids released to rice production, which have greatly elevated the yield potential and grain quality of rice varieties. The enhanced molecular understanding will offer new strategies for the development of EGMS lines thus further improving two-line hybrid breeding of rice as well as other crops.

    One approach to reducing occupational stress during an economic recession is to share work amongst employees. This may include reducing employees' working hours to avoid redundancies. To examine whether work-sharing influenced the psychosocial work environment and depressive symptoms encountered by Japanese employees, and to determine which psychosocial factors predict employees' mental health during an economic recession. A survey was performed in a Japanese manufacturing company at the beginning (T1) and end (T2) of a 6-month period during the 2008 economic recession using the validated Job Content Questionnaire (JCQ) and Self-Rating Depression Scale (SDS). Three hundred and thirty-six male employees completed the questionnaire. Twenty-four per cent of participants showed depressive symptoms at T1. Despite reductions in employees' working hours and job strain (P < 0.001), SDS scores showed no change after 6 months. Logistic regression analyses showed that low social support between the two surveys was associated with depressive symptoms at T2 after adjusting for demographic, lifestyle, workplace factors, scheduled working hours and depressive symptoms at T1. Reductions in job strain did not affect employees' depressive symptoms. Employees with low social support during the study had a significantly higher risk of having depressive symptoms. These findings indicate that social and emotional support within the workplace is important during the work-sharing period. © The Author 2017.

    Background Pigeonpea [Cajanus cajan (L.) Millspaugh], one of the most important food legumes of semi-arid tropical and subtropical regions, has limited genomic resources, particularly expressed sequence based (genic) markers. We report a comprehensive set of validated genic simple sequence repeat (SSR) markers using deep transcriptome sequencing, and its application in genetic diversity analysis and mapping. Results In this study, 43,324 transcriptome shotgun assembly unigene contigs were assembled from 1.696 million 454 GS-FLX sequence reads of separate pooled cDNA libraries prepared from leaf, root, stem and immature seed of two pigeonpea varieties, Asha and UPAS 120. A total of 3,771 genic-SSR loci, excluding homopolymeric and compound repeats, were identified; of which 2,877 PCR primer pairs were designed for marker development. Dinucleotide was the most common repeat motif with a frequency of 60.41%, followed by tri- (34.52%), hexa- (2.62%), tetra- (1.67%) and pentanucleotide (0.76%) repeat motifs. Primers were synthesized and tested for 772 of these loci with repeat lengths of ≥18 bp. Of these, 550 markers were validated for consistent amplification in eight diverse pigeonpea varieties; 71 were found to be polymorphic on agarose gel electrophoresis. Genetic diversity analysis was done on 22 pigeonpea varieties and eight wild species using 20 highly polymorphic genic-SSR markers. The number of alleles at these loci ranged from 4-10 and the polymorphism information content values ranged from 0.46 to 0.72. Neighbor-joining dendrogram showed distinct separation of the different groups of pigeonpea cultivars and wild species. Deep transcriptome sequencing of the two parental lines helped in silico identification of polymorphic genic-SSR loci to facilitate the rapid development of an intra-species reference genetic map, a subset of which was validated for expected allelic segregation in the reference mapping population. Conclusion We developed 550 validated genic

    We have developed a novel hybridization platform that utilizes nuclear male sterility to produce hybrids in maize and other cross-pollinating crops. A key component of this platform is a process termed Seed Production Technology (SPT). This process incorporates a transgenic SPT maintainer line capable of propagating nontransgenic nuclear male-sterile lines for use as female parents in hybrid production. The maize SPT maintainer line is a homozygous recessive male sterile transformed with a SPT construct containing (i) a complementary wild-type male fertility gene to restore fertility, (ii) an α-amylase gene to disrupt pollination and (iii) a seed colour marker gene. The sporophytic wild-type allele complements the recessive mutation, enabling the development of pollen grains, all of which carry the recessive allele but with only half carrying the SPT transgenes. Pollen grains with the SPT transgenes exhibit starch depletion resulting from expression of α-amylase and are unable to germinate. Pollen grains that do not carry the SPT transgenes are nontransgenic and are able to fertilize homozygous mutant plants, resulting in nontransgenic male-sterile progeny for use as female parents. Because transgenic SPT maintainer seeds express a red fluorescent protein, they can be detected and efficiently separated from seeds that do not contain the SPT transgenes by mechanical colour sorting. The SPT process has the potential to replace current approaches to pollen control in commercial maize hybrid seed production. It also has important applications for other cross-pollinating crops where it can unlock the potential for greater hybrid productivity through expanding the parental germplasm pool. © 2015 The Authors.

    A total of 8375 genic simple sequence repeat (SSR) loci were discovered from a unigene set assembled from 116282 transcriptomic unigenes in this study. Dinucleotide repeat motifs were the most common with a frequency of 65.11%, followed by trinucleotide (32.81%). A total of 4100 primer pairs were designed from the SSR loci. Of these, 343 primer pairs (repeat length ≥15 bp) were synthesized with an M13 tail and tested for stable amplification and polymorphism in four Pyrus accessions. After the preliminary test, 104 polymorphic genic SSR markers were developed; dinucleotide and trinucleotide repeats represented 97.11% (101) of these. Twenty-eight polymorphic genic SSR markers were selected randomly to further validate genetic diversity among 28 Pyrus accessions. These markers displayed a high level of polymorphism. The number of alleles at these SSR loci ranged from 2 to 17, with a mean of 9.43 alleles per locus, and the polymorphism information content (PIC) values ranged from 0.26 to 0.91. The UPGMA (unweighted pair-group method with arithmetic average) cluster analysis grouped the 28 Pyrus accessions into two groups: Oriental pears and Occidental pears, which are congruent to the traditional taxonomy, demonstrating their effectiveness in analyzing Pyrus phylogenetic relationships, enriching rare Pyrus EST-SSR resources, and confirming the potential value of a pear transcriptome database for the development of new SSR markers.

    Copy number variation (CNV) impacting protein-coding genes contributes significantly to human diversity and disease. Here we characterized the rates and properties of rare genic CNV (intolerance to CNVs that demonstrated moderate correlation with measures of genic constraint based on single-nucleotide variation (SNV) and was independently correlated with measures of evolutionary conservation. For individuals with schizophrenia, genes impacted by CNVs were more intolerant than in controls. ExAC CNV data constitutes a critical component of an integrated database spanning the spectrum of human genetic variation, aiding the interpretation of personal genomes as well as population-based disease studies. These data are freely available for download and visualization online. PMID:27533299

    In this paper we study how the Great Recession affected university students in terms of performance, with a special focus on the dropout probability. To do so, we use individual-level data on a representative sample of university students in Italy in 2007 and 2011. We measure the severity of the recession in terms of increases in adult and youth unemployment rate and we exploit geographical variation to achieve identification. On the one hand, an increase in adult male unemployment rate deter...

    Full Text Available Abstract Background The basis of genome size variation remains an outstanding question because DNA sequence data are lacking for organisms with large genomes. Sixteen BAC clones from the Mexican axolotl (Ambystoma mexicanum: c-value = 32 × 109 bp were isolated and sequenced to characterize the structure of genic regions. Results Annotation of genes within BACs showed that axolotl introns are on average 10× longer than orthologous vertebrate introns and they are predicted to contain more functional elements, including miRNAs and snoRNAs. Loci were discovered within BACs for two novel EST transcripts that are differentially expressed during spinal cord regeneration and skin metamorphosis. Unexpectedly, a third novel gene was also discovered while manually annotating BACs. Analysis of human-axolotl protein-coding sequences suggests there are 2% more lineage specific genes in the axolotl genome than the human genome, but the great majority (86% of genes between axolotl and human are predicted to be 1:1 orthologs. Considering that axolotl genes are on average 5× larger than human genes, the genic component of the salamander genome is estimated to be incredibly large, approximately 2.8 gigabases! Conclusion This study shows that a large salamander genome has a correspondingly large genic component, primarily because genes have incredibly long introns. These intronic sequences may harbor novel coding and non-coding sequences that regulate biological processes that are unique to salamanders.

    Miscanthus, a nonfood plant with high potential as a biofuel, has been used in Europe and the United States. The selection of a cultivar with high biomass, photosynthetic efficiency, and stress resistance from wild populations has become an important issue. New genic microsatellite markers will aid the assessment of genetic diversity for different strains. Twelve polymorphic microsatellite markers derived from the transcriptome of Miscanthus sinensis fo. glaber were identified and screened on 80 individuals of M. sinensis. The number of alleles per locus ranged from 6 to 12, and the mean expected heterozygosity was 0.75. Cross-taxa transferability revealed that all loci can be applied to all varieties of M. sinensis, as well as the closely related species M. floridulus. These new genic microsatellite markers are useful for characterizing different traits in breeding programs or to select genes useful for biofuel.

    2012-09-01

    A convenience sample of 60 subjects (27 male; 33 female) with tongue piercings (case group) and 120 subjects (43 male; 77 female) without tongue piercings (control group), ranging in age from 13 to 28 years, were identified from a mix of races living in a geographic area of low socioeconomic status in Brazil. Subjects were recruited from school groups and university centers between January 2008 and March 2009. For each case, 2 controls were selected on a consecutive basis from the same school according to criteria that included age, gender, smoking, and previous orthodontic treatment. Exclusion criteria included individuals with systemic diseases that might compromise the immune system, as well as antibiotics within 3 months or other medications that could affect the gingival tissues. The key study factor was the use or nonuse of tongue piercings (jewelry). The analysis compared periodontal parameters, such as the occurrence, location, and severity of gingival recession, in subjects with and without tongue jewelry. Gingival recession in the anterior lingual mandibular region was assessed as the primary outcome measure. The study sample was divided according to the presence or absence of gingival recession as well as the severity (1-2, 3, and ≥ 4 mm) of gingival recession. The average age of subjects was similar in the case and control groups (18.9 versus 17.7 years, respectively). Fractures of the anterior teeth were present significantly more frequently in cases than controls (26.7% versus 11.7%, respectively; P piercings (OR = 11.0, 95% confidence interval [CI] 5.02-24.09, P <.001). The severity of recession in this region was also significantly higher (calculated using an ordinal scale) in cases than in controls (P < .001). The final multivariate logistic regression model for occurrence of gingival recession included the variables tongue jewelry (yes/no), age, male gender, and the presence of bleeding on probing in the anterior region.

    Full Text Available We describe a case of anhidrotic ectodermal dysplasia (AED with an autosomal recessive mode of inheritance, a very rare entity, in a 2-year-old female child of two asymptomatic, consanguineous parents. Their previous child also had a similar condition. Autosomal recessive AED (AR-AED can have its full expression both in males and females and it is clinically indistinguishable from the x-linked recessive AED (XL-AED, which is the most common type of ectodermal dysplasia. Unlike the partially symptomatic carriers of XL-AED, the heterozygotes of AR-AED are phenotypically asymptomatic.

    In recent years, cancer case counts in the U.S. underwent a large, rapid decline-an unexpected change given population growth for older persons at highest cancer risk. As these declines coincided with the Great Recession, we examined whether they were related to economic conditions. Using California Cancer Registry data from California's 30 most populous counties, we analyzed trends in cancer incidence during pre-recession (1996-2007) and recession/recovery (2008-2012) periods for all cancers combined and the ten most common sites. We evaluated the recession's association with rates using a multifactorial index that measured recession impact, and modeled associations between case counts and county-level unemployment rates using Poisson regression. Yearly cancer incidence rate declines were greater during the recession/recovery (3.3% among males, 1.4% among females) than before (0.7 and 0.5%, respectively), particularly for prostate, lung, and colorectal cancers. Lower case counts, especially for prostate and liver cancer among males and breast cancer, melanoma, and ovarian cancer among females, were associated with higher unemployment rates, irrespective of time period, but independent of secular effects. The associations for melanoma translated up to a 3.6% decrease in cases with each 1% increase in unemployment. Incidence declines were not greater in counties with higher recession impact index. Although recent declines in incidence of certain cancers are not differentially impacted by economic conditions related to the Great Recession relative to pre-recession conditions, the large recent absolute declines in the case counts of some cancer may be attributable to the large declines in unemployment in the recessionary period. This may occur through decreased engagement in preventive health behaviors, particularly for clinically less urgent cancers. Continued monitoring of trends is important to detect any rises in incidence rates as deferred diagnoses come to

    Proso millet ( Panicum miliaceum ; Poaceae) is a minor crop with good nutritional qualities and strong tolerance to drought stress and soil infertility. However, studies on genetic diversity have been limited due to a lack of efficient genetic markers. Illumina sequencing technology was used to generate short read sequences of proso millet, and de novo transcriptome assemblies were used to develop a de novo assembly of proso millet. Genic simple sequence repeat (SSR) markers were identified and used to detect polymorphism among 56 accessions. Population structure and genetic similarity coefficient were estimated. In total, 25,341 unique gene sequences and 4724 SSR loci were obtained from the transcriptome, of which 229 pairs of SSR primers were validated, which resulted in 14 polymorphic genic SSR primers exhibiting 43 total alleles. According to the ratio of polymorphic markers (6.1%, 14/229), there are potentially 288 polymorphic genic SSR markers available for genetic assay development in the future. Bayesian population analyses showed that the 56 accessions comprised two distinct groups. A genetic structure and cluster assay indicated that the accessions from the Loess Plateau of China shared a high genetic similarity coefficient with those from other regions and that there was no correlation between genetic diversity and geographic origin. The transcriptome sequencing data and millet-specific SSR markers developed in this study establish an excellent resource for gene discovery and may improve the development of breeding programs in proso millet in the future.

    Cowpea [Vigna unguiculata (L.) Walp.] is one of the most important legumes in tropical and semi-arid regions. However, there is relatively little genomic information available for genetic research on and breeding of cowpea. The objectives of this study were to analyse the cowpea transcriptome and develop genic molecular markers for future genetic studies of this genus. Approximately 54 million high-quality cDNA sequence reads were obtained from cowpea based on Illumina paired-end sequencing technology and were de novo assembled to generate 47,899 unigenes with an N50 length of 1534 bp. Sequence similarity analysis revealed 36,289 unigenes (75.8%) with significant similarity to known proteins in the non-redundant (Nr) protein database, 23,471 unigenes (49.0%) with BLAST hits in the Swiss-Prot database, and 20,654 unigenes (43.1%) with high similarity in the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Further analysis identified 5560 simple sequence repeats (SSRs) as potential genic molecular markers. Validating a random set of 500 SSR markers yielded 54 polymorphic markers among 32 cowpea accessions. This transcriptomic analysis of cowpea provided a valuable set of genomic data for characterizing genes with important agronomic traits in Vigna unguiculata and a new set of genic SSR markers for further genetic studies and breeding in cowpea and related Vigna species.

    Mapping the geo-genic radon potential in Buzau County is part of a research project aiming to apply research for sustainable development and economic growth following the principles of geo-conservation in order to support the 'Buzau Land' UNESCO Geo-park initiative. The mapping of geo-genic radon will be used as an overview for planning purposes. The main geological formations of the studied area were identified as Cretaceous and Paleogene flysch, included in a thin-skinned nappes pile and consisting of alternating sandstones, marls, clays and, subordinately, conglomerates, all tightly folded or faulted. Significant variations in the concentration of radon were therefore determined in the ground. However, no high values were determined, the maximum measured activity concentration being 101.6 kBq m -3 . (authors)

    Sesame (Sesamum indicum L.) is one of the most important oil crops; however, a lack of useful molecular markers hinders current genetic research. We performed transcriptome sequencing of samples from different sesame growth and developmental stages, and mining of genic-SSR markers to identify valuable markers for sesame molecular genetics research. In this study, 75 bp and 100 bp paired-end RNA-seq was used to sequence 24 cDNA libraries, and 42,566 uni-transcripts were assembled from more than 260 million filtered reads. The total length of uni-transcript sequences was 47.99 Mb, and 7,324 SSRs (SSRs ≥15 bp) and 4,440 SSRs (SSRs ≥18 bp) were identified. On average, there was one genic-SSR per 6.55 kb (SSRs ≥15 bp) or 10.81 kb (SSRs ≥18 bp). Among perfect SSRs (≥18 bp), di-nucleotide motifs (48.01%) were the most abundant, followed by tri- (20.96%), hexa- (25.37%), penta- (2.97%), tetra- (2.12%), and mono-nucleotides (0.57%). The top four motif repeats were (AG/CT)n [1,268 (34.51%)], (CA/TG)n [281 (7.65%)], (AT/AT)n [215 (5.85%)], and (GAA/TTC)n [131 (3.57%)]. A total of 2,164 SSR primer pairs were identified in the 4,440 SSR-containing sequences (≥18 bp), and 300 SSR primer pairs were randomly chosen for validation. These SSR markers were amplified and validated in 25 sesame accessions (24 cultivated accessions, one wild species). 276 (92.0%) primer pairs yielded PCR amplification products in 24 cultivars. Thirty two primer pairs (11.59%) exhibited polymorphisms. Moreover, 203 primer pairs (67.67%) yielded PCR amplicons in the wild accession and 167 (60.51%) were polymorphic between species. A UPGMA dendrogram based on genetic similarity coefficients showed that the correlation between genotype and geographical source was low and that the genetic basis of sesame in China is narrow, as previously reported. The 32 polymorphic primer pairs were validated using an F2 mapping population; 18 primer pairs exhibited polymorphisms between the parents, and 14

    The differential expression of male sterility induced by space flight with male fertility was studied using cDNA-AFLP technology. Total RNA was isolated from anther of male sterility and male fertility. Nine differential expression cDNA fragments were obtained with 16 primer combinations. The differential cDNA fragments were eluted, cloned and sequenced. Then half-quantitative RT-PCR was used to stuy the differential expressions of 4 development stages between sterility and fertility. Sequencing analysis shown 2 fragments from male sterility might be novel genes. Four fragments from male fertility were homology as chalcone and stilbene synthases, putative acyl CoA dehydrogenase, putative protein kinases and putative glycine decarboxylase. All these proteins might participate in the energy metabolisms, substance metabolisms or signal pollen development, Z8 took on increasing expression during the middle period of pollen development. These results just met the demand of more energy and more substance during the pollen development. (authors)

    This study examines the changes in health care utilization for mental health disorders among patients who were diagnosed with depressive and/or anxiety disorders during the Great Recession 2007-2009 in the USA. Negative binomial regressions are used to estimate the association of the economic recession and mental health care use for females and males separately. Results show that prescription drug utilization (e.g., antidepressants, psychotropic medications) increased significantly during the economic recession 2007-2009 for both females and males. Physician visits for mental health disorders decreased during the same period. Results show that racial disparities in mental health care might have increased, while ethnic disparities persisted during the Great Recession. Future research should separately examine mental health care utilization by gender and race/ethnicity.

In M 2 , the single plant seeds were grown in progeny rows and the bulked seeds were grown as bulks. 25 male sterile plants were screened from M 2 . 10 of the 25 male sterile plants were from the progenies of the single plant seeds and 15 were from the progenies of the bulked seeds. In further genetic research of the 25 male sterile plants in M 3 and M 4 , 6 separate genic male sterile (GMS) lines were identified. Their male sterility was stable and was controlled by a pair of alleles, male fertility being dominant to sterility. (author)

    The exploitation of male sterility systems has enabled the commercialization of heterosis in rice, with greatly increased yield and total production of this major staple food crop. Hybrid rice, which was adopted in the 1970s, now covers nearly 13.6 million hectares each year in China alone. Various types of cytoplasmic male sterility (CMS) and environment-conditioned genic male sterility (EGMS) systems have been applied in hybrid rice production. In this paper, recent advances in genetics, biochemistry, and molecular biology are reviewed with an emphasis on major male sterility systems in rice: five CMS systems, i.e., BT-, HL-, WA-, LD- and CW- CMS, and two EGMS systems, i.e., photoperiod- and temperature-sensitive genic male sterility (P/TGMS). The interaction of chimeric mitochondrial genes with nuclear genes causes CMS, which may be restored by restorer of fertility (Rf) genes. The PGMS, on the other hand, is conditioned by a non-coding RNA gene. A survey of the various CMS and EGMS lines used in hybrid rice production over the past three decades shows that the two-line system utilizing EGMS lines is playing a steadily larger role and TGMS lines predominate the current two-line system for hybrid rice production. The findings and experience gained during development and application of, and research on male sterility in rice not only advanced our understanding but also shed light on applications to other crops.

    A growing body of research evidence from countries around the world indicates that economic recession is associated with increases in suicide, particularly in males of working age. To explore contributory and ameliorating factors associated with economic recession and suicide and thereby stimulate further research in this area and encourage policy makers to consider how best to reduce the impact of recession on mental health and suicidal behaviour. We conducted a selective review of the worldwide literature focusing on possible risk factors, mechanisms and preventative strategies for suicidal behaviour linked to economic recession. A model of how recession might affect suicide rates is presented. A major and often prolonged effect of recession is on unemployment and job insecurity. Other important effects include those exerted by financial loss, bankruptcy and home repossession. It is proposed these factors may lead directly or indirectly to mental health problems such as depression, anxiety and binge drinking and then to suicidal behaviour. Countries with active labour market programmes and sustained welfare spending during recessions have less marked increases in suicide rates than those that cut spending on welfare and job-search initiatives for the unemployed. Other measures likely to help include targeted interventions for unemployed people, membership of social organisations and responsible media reporting. Good primary care and mental health services are needed to cope with increased demand in times of economic recession but some governments have in fact reduced healthcare spending as an austerity measure. The research evidence linking recession, unemployment and suicide is substantial, but the evidence for the other mechanisms we have investigated is much more tentative. We describe the limitations of the existing body of research as well as make suggestions for future research into the effects of economic recession on suicidal behaviour. © The Author

  5. Gender Differences in Mental Health Outcomes before, during, and after the Great Recession.

    Dagher, Rada K; Chen, Jie; Thomas, Stephen B

    2015-01-01

    We examined gender differences in mental health outcomes during and post-recession versus pre-recession. We utilized 2005-2006, 2008-2009, and 2010-2011 data from the Medical Expenditure Panel Survey. Females had lower odds of depression diagnoses during and post-recession and better mental health during the recession, but higher odds of anxiety diagnoses post-recession. Males had lower odds of depression diagnoses and better mental health during and post-recession and lower Kessler 6 scores post-recession. We conducted stratified analyses, which confirmed that the aforementioned findings were consistent across the four different regions of the U.S., by employment status, income and health care utilization. Importantly, we found that the higher odds of anxiety diagnoses among females after the recession were mainly prominent among specific subgroups of females: those who lived in the Northeast or the Midwest, the unemployed, and those with low household income. Gender differences in mental health in association with the economic recession highlight the importance of policymakers taking these differences into consideration when designing economic and social policies to address economic downturns. Future research should examine the reasons behind the decreased depression diagnoses among both genders, and whether they signify decreased mental healthcare utilization or increased social support and more time for exercise and leisure activities.

    In this article recession magnitudes in Europe, the USA and Japan during the Great Recession are compared. The strongest recessions (of severe category) occurred in Latvia, Lithuania and Estonia, while recessions in Japan and the USA were significantly weaker. Even the strongest recession (in Latvia) was found smaller in its magnitude than the Great Depression 1929-1933 in the USA. Hence, comparisons of the Great Recession to the Great Depression in the literature are somewhat exaggerated.

    Both induced and spontaneously arising male sterility mutants exist in a number of important plant species. These mutants are somewhat unique in that they effect procedures for breeding improved varieties. They allow for the possibility of easily obtaining large numbers of hybrids, population breeding systems and the production of hybrid varieties. These mutants are normally classified as cytoplasmic mutants or chromosomal mutants, the latter also being referred to as nuclear or genic mutants. Specific examples of these types of sterility are examined in relation to the breeding system of the species and their potential use for varietal development. Male sterility in diploid and polyploid species is compared, with reference to gene duplication in polyploids. The mechanism of male sterility is examined in the various species at the anatomical and biochemical levels. Methods of isolating male sterility mutants are compared and a specific example is outlined for hexaploid wheat. Future use of male sterility mutants for improving varieties of various crops is examined. (author)

    Sugar maple (Acer saccharum Marsh.) is a hardwood tree species native to northeastern North America and economically valued for its wood and sap. Yet, few molecular genetic resources have been developed for this species to date. Microsatellite markers have been a useful tool in population genetics, e.g., to monitor genetic variation and to analyze gene flow patterns. The objective of this study is to develop a reference transcriptome and microsatellite markers in sugar maple. A set of 117,861 putative unique transcripts were assembled using 29.2 Gb of RNA sequencing data derived from different tissues and stress treatments. From this set of sequences a total of 1068 microsatellite motifs were identified. Out of 58 genic microsatellite markers tested on a population of 47 sugar maple trees in upper Michigan, 22 amplified well, of which 16 were polymorphic and 6 were monomorphic. Values for expected heterozygosity varied from 0.224 to 0.726 for individual loci. Of the 16 polymorphic markers, 15 exhibited transferability to other Acer L. species. Genic microsatellite markers can be applied to analyze genetic variation in potentially adaptive genes relative to genomic reference markers as a basis for the management of sugar maple genetic resources in the face of climate change.

    Full Text Available Genomic resources for conventional breeding programs are extremely limited for coniferous trees, and existing simple sequence repeat markers are usually identified through the laborious process of hybridization screening. Therefore, this study aimed to identify gene-based microsatellites in the Chinese fir, Cunninghamia lanceolata (Lamb. Hook by screening transcript data. We identified 5200 microsatellites. Trinucleotide motifs were most common (47.94% and were followed by tetranucleotide motifs (24.92%. The AG/CT motif (43.93% was the most abundant dinucleotide repeat, whereas AAG/CTT (25.07% was the most common trinucleotide repeat. A total of 411 microsatellite primer pairs were designed and 97 polymorphic loci were identified by 8 genotypes. The number of alleles per locus (Na in these polymorphic loci ranged from 2 to 5 (mean, 2.640, the Ho values were 0.000-1.000 (mean, 0.479, and the HE values were 0.125-0.775 (mean, 0.462. The polymorphic information content (PIC values were 0.110-0.715 (mean, 0.383. Seventy-two of the 97 polymorphic markers (74.23% were present within genes with predicted functions. In addition, in genetic diversity and segregation analyses of 16 genotypes, only 5.88% of the polymorphic loci displayed segregation distortion at the p<0.05 level. Transferable amplification of a randomly selected set of 30 genic microsatellites showed that transferability decreased with increasing evolutionary distance between C. lanceolata and target conifers. Thus, these 97 genic markers will be useful for genetic diversity analysis, germplasm characterization, genome mapping and marker-assisted breeding in C. lanceolata, and evolutionary genetic analysis in Taxodiaceae.

    Male live births slightly exceed female live births by approximately 3%. The ratio of male to total live births is conventionally represented as M/F. Many factors have been shown to affect M/F, mainly privation, toxins, and stress, all of which reduce M/F. Population stress may be engendered by natural phenomena such as earthquakes and man-made events such as short wars, terrorist attacks, and contracting economies. This study was conducted to ascertain whether the onset of the "Great Recession" (2007) was associated with changes in M/F in the United States (US). Annual monthly live births by gender for January 2006 to December 2008 were obtained from United States Centres for Disease Control and Prevention. In 2007, there were 4316233 live births [M/F: 0.51157; 95% confidence intervals: 0.51110-0.51205). M/F rose between January and June, and then fell sharply between August and December. M/F was statistically significantly lower in the second half of 2007 (p=0.007). The dip in M/F from June to July was also significant (p=0.02). These findings were not replicated in the amalgamated data for 2006 and 2008. The United States housing boom of the mid-2000s was fueled by rising house prices and cheap mortgages given to credit-poor buyers. A halt in rising house prices resulted in defaults and foreclosures, triggering the worst financial crisis since the Great Depression. The associated stress appears to have decreased M/F in the US.

    High performance liquid chromatography (HPLC) was adopted to analyze the content of endogenous hormones such as zeatin (ZT), gibberellin (GA s ), auxin (IAA) and abscisic acid (ABA) in male fertile plants and male sterile plants of maize derived from sister-cross population, which was produced with male sterile mutant induced by space flight. Exogenous GA s treatment was applied to plants of sister-cross population of maize, and the fertility of the maize plant both in the exogenous GA s treatment plots and the control plot was investigated. The results showed that the fertility segregation ratios of sister-cross populations did not change with exogenous GA s treatment. At the seedling stage, only the differences of IAA and ABA contents in leaf between fertile and sterile plants were significant at the 0. 05 level, and the differences of ZT, GA s , IAA and ABA contents between sterile and fertile plants all were at 0. 05 or 0. 01 level significant, at the jointing stage. At the uninucleate microspore stage the differences of IAA and ABA contents in anther were significant at 0. 01 level, but at the binucleate pollen stage only the difference of ABA content was significant at 0. 01 level. During the four different developmental stages, the contents of ZT, GA s and IAA were higher in fertile plants than in sterile plants, but the content of ABA was lower in fertile plants than in sterile plants in the two different tissues. It was concluded that exogenous GA s treatment could not alter the fertility of maize plants, so this mutant did not belong to the GA s sensitive type. The changes of the hormone level or the hormones ratio might be related to the pollen abortion of the male sterile material used in this experiment, and it seems that ABA and IAA may have a closer relationship with the fertility expression of the material used in this experiment than ZT and GA s according to the significance tests.

    Full Text Available Background: Gingival recession is the most common and undesirable condition of the gingiva. The aim of study was to investigate the aetiology and severity of gingival recession in a Greek adult population sample. Methods : The study was performed on 165 males and 179 females, 18-68 years old who sought dental treatment in a private dental practice and showed gingival recession. All subjects were clinically examined and answered questions regarding their oral hygiene habits such as the type of toothbrush, frequency of brushing and method of brushing. The association between gingival recession and the following parameters was assessed: plaque score, gingival score and tooth position. Statistical analysis of the results was accomplished using chi-square test (α = 0.05. Results: The majority (79.4% of the patients showed grade I gingival recession and 15.3% showed grade II gingival recession. The maxillary 1 st and 2 nd molars (35.3% and the mandibular 1 st and 2 nd molars (28.7% were the teeth most frequently affected by root surface exposure. Patients with sub-gingival calculus, bacterial plaque and gingival inflammation (P < 0.05, malpositioned teeth (P < 0.001, horizontal brushing method, medium type of toothbrush (P < 0.001 and brushing once daily (P < 0.001 appeared to be the most common precipitating aetiological factor for gingival recession. Conclusion: According to the results of the present study, gingival recession was the result of more than one factor acting together. Horizontal brushing method, usage of medium type toothbrush and tooth brushing once daily were found to be more associated with gingival recession.

    The present study evaluates the effect of supplementing culture medium with α-tocopherol acetate on the yield of sex-linked recessive lethal mutants induced by X-irradiation in mature sperm of Drosophila. Although tocopherol treatment of males had no impact on the yield of mutations, a drastic reduction in mutation frequency was observed when irradiated males were mated to females raised and subsequently maintained on tocopherol-enriched diet.

    Full Text Available The objective of this work was to select and use microsatellite markers, to map genomic regions associated with the genetic control of thermosensitive genic male sterility (TGMS in rice. An F2 population, derived from the cross between fertile and TGMS indica lines, was used to construct a microsatellite-based genetic map of rice. The TGMS phenotype showed a continuous variation in the segregant population. A low level of segregation distortion was detected in the F2 (14.65%, whose cause was found to be zygotic selection. There was no evidence suggesting a cause-effect relationship between zygotic selection and the control of TGMS in this cross. A linkage map comprising 1,213.3 cM was constructed based on the segregation data of the F2 population. Ninety-five out of 116 microsatellite polymorphic markers were assembled into 11 linkage groups, with an average of 12.77 cM between two adjacent marker loci. The phenotypic and genotypic data allowed for the identification of three new quantitative trait loci (QTL for thermosensitive genic male sterility in indica rice. Two of the QTL were mapped on chromosomes that, so far, have not been associated with the genetic control of the TGMS trait (chromosomes 1 and 12. The third QTL was mapped on chromosome 7, where a TGMS locus (tms2 has recently been mapped. Allelic tests will have to be developed, in order to clarify if the two regions are the same or not.O objetivo deste estudo foi selecionar e utilizar marcadores microssatélites, para mapear as regi��es genômicas associadas ao controle genético de macho-esterilidade termossensível (TGMS em arroz. Uma popu- lação F2, derivada do cruzamento entre linhagens indica fértil e TGMS, foi usada para construir um mapa genético de arroz, baseado em marcadores microssatélites. O fenótipo TGMS analisado apresentou uma variação contínua na população segregante. Um baixo nível de distorção da segregação foi detectado na população segregante

    Autosomal recessive omodysplasia (MIM 258315) is a rare skeletal dysplasia characterized by severe congenital micromelia with shortening and distal tapering of the humeri and femora to give a club-like appearance. Fewer than 20 cases have been reported in the literature so far. The purpose of this study was to more clearly describe the clinical and radiographic phenotypes and their changes with age. Five new patients, including two sibs, with autosomal recessive omodysplasia are presented. Clinical features are rhizomelic dwarfism with limited extension of elbows and knees and a distinct face with a short nose, depressed nasal bridge, long philtrum, midline haemangiomas in infants and cryptorchidism in males. Radiological findings are distal hypoplasia of the short humerus and femur with characteristic radial dislocation and radioulnar diastasis. Based on a review of these and 16 previously reported patients, the regressive nature of the humerofemoral changes and the obvious male predominance are stressed. Phenotypic similarities with the atelosteogenesis group of disorders and with diastrophic dysplasia suggest common pathogenetic mechanisms. (orig.)

  20. Induction of Male sterile mutants in vegetable crops

    International Nuclear Information System (INIS)

    Nagata, Nobuhiko

    1982-01-01

    The cultivars of vegetable crops in Japan are almost all F 1 hybrid lines. These hybrid cultivars are superior in yield, quality and uniformity by heterosis, and play an important role in the protection of breeder's rights. Utilization of male sterile mutants has such advantages as the reduction of cost for F 1 production by saving labor, production of better seeds, that is, pollination without emasculation and avoidance of contamination caused by self pollination. Male sterility must be used for some species in which seed production is difficult because of tiny flowers and meager seed production by artificial crossing such as carrot and onion, and those in which pollination by bag or emasculation is expensive such as tomato, and sweet pepper. However, for vegetable crop breeeding, the induction and use of genic male sterility are more difficult than for other crops, considering the economy and efficiency of research because the type of cultivars needed changes rapidly.

    How have suicide rates responded to the marked increase in unemployment spurred by the Great Recession? Our paper puts this issue into a wider perspective by assessing (1) whether the unemployment-suicide link is modified by the degree of unemployment protection, and (2) whether the effect on suicide of the present crisis differs from the effects of previous economic downturns. We analysed the unemployment-suicide link using time-series data for 30 countries spanning the period 1960-2012. Separate fixed-effects models were estimated for each of five welfare state regimes with different levels of unemployment protection (Eastern, Southern, Anglo-Saxon, Bismarckian and Scandinavian). We included an interaction term to capture the possible excess effect of unemployment during the Great Recession. The largest unemployment increases occurred in the welfare state regimes with the least generous unemployment protection. The unemployment effect on male suicides was statistically significant in all welfare regimes, except the Scandinavian one. The effect on female suicides was significant only in the eastern European country group. There was a significant gradient in the effects, being stronger the less generous the unemployment protection. The interaction term capturing the possible excess effect of unemployment during the financial crisis was not significant. Our findings suggest that the more generous the unemployment protection the weaker the detrimental impact on suicide of the increasing unemployment during the Great Recession.

    Male sterility is an important mechanism for the production of hybrid seeds in watermelon. Although fruit development has been studied extensively in watermelon, there are no reports on gene expression in floral organs. In this study, RNA-sequencing (RNA-seq) was performed in two near-isogenic watermelon lines (genic male sterile [GMS] line, DAH3615-MS and male fertile line, DAH3615) to identify the differentially expressed genes (DEGs) related to male sterility. DEG analysis showed that 1259 genes were significantly associated with male sterility at a FDR P-value of watermelon. This analysis revealed essential genes responsible for stamen development, including pollen development and pollen tube elongation, and allowed their functional classification. These results provided new information on global mechanisms related to male sterility in watermelon.

    The pen shell ( Atrina pectinata) is a large wedge-shaped bivalve, which belongs to family Pinnidae. Due to its large and nutritious adductor muscle, it is the popular seafood with high commercial value in Asia-Pacific countries. However, limiting genomic and transcriptomic data have hampered its genetic investigations. In this study, the transcriptome of A. pectinata was deeply sequenced using Illumina pair-end sequencing technology. After assembling, a total of 127263 unigenes were obtained. Functional annotation indicated that the highest percentage of unigenes (18.60%) was annotated on GO database, followed by 18.44% on PFAM database and 17.04% on NR database. There were 270 biological pathways matched with those in KEGG database. Furthermore, a total of 23452 potential simple sequence repeats (SSRs) were identified, of them the most abundant type was mono-nucleotide repeats (12902, 55.01%), which was followed by di-nucleotide (8132, 34.68%), tri-nucleotide (2010, 8.57%), tetra-nucleotide (401, 1.71%), and penta-nucleotide (7, 0.03%) repeats. Sixty SSRs were selected for validating and developing genic SSR markers, of them 23 showed polymorphism in a cultured population with the average observed and expected heterozygosities of 0.412 and 0.579, respectively. In this study, we established the first comprehensive transcript dataset of A. pectinata genes. Our results demonstrated that RNA-Seq is a fast and cost-effective method for genic SSR development in non-model species.

    Intestinal complications after radiotherapy are caused by transmural fibrosis (RIF) that impaired the quality of life of cancer patient survivors and considered permanent and irreversible until recently but recent molecular characterization of RIF offered new targeted opportunities for the development of anti-fibrotic therapies. In this thesis work, we identified activation of the Rho/ROCK pathway which is involved in the persistence of fibro-genic signals. In addition, among the new anti-fibrotic targeted therapies, we asked whether specific inhibition of Rho pathway, by Pravastatin could elicit anti-fibrotic action. Therefore, the therapeutic relevance of pravastatin as anti-fibrotic strategy was validated using two different models of intestinal and lung fibrosis. As statins are safe and well tolerated compounds, phase II clinical trial is envisioned within the next months to reverse established fibrosis after radiotherapy. (author)

    Identifying the underlying causes of disease requires accurate interpretation of genetic variants. Current methods ineffectively capture pathogenic non-coding variants in genic regions, resulting in overlooking synonymous and intronic variants when searching for disease risk. Here we present the Transcript-inferred Pathogenicity (TraP) score, which uses sequence context alterations to reliably identify non-coding variation that causes disease. High TraP scores single out extremely rare variants with lower minor allele frequencies than missense variants. TraP accurately distinguishes known pathogenic and benign variants in synonymous (AUC = 0.88) and intronic (AUC = 0.83) public datasets, dismissing benign variants with exceptionally high specificity. TraP analysis of 843 exomes from epilepsy family trios identifies synonymous variants in known epilepsy genes, thus pinpointing risk factors of disease from non-coding sequence data. TraP outperforms leading methods in identifying non-coding variants that are pathogenic and is therefore a valuable tool for use in gene discovery and the interpretation of personal genomes.While non-coding synonymous and intronic variants are often not under strong selective constraint, they can be pathogenic through affecting splicing or transcription. Here, the authors develop a score that uses sequence context alterations to predict pathogenicity of synonymous and non-coding genetic variants, and provide a web server of pre-computed scores.

    Home ownership as opposed to renting is associated with lower rates of food insecurity, the latter being a marker of household economic deprivation associated with adverse health outcomes. It is unclear whether this relationship persists during a major economic decline, or whether different subgroups of home owners are equally protected. The 2008-2009 recession in Canada was tied to events in the United States related to inappropriate mortgage financing; the impact of the recession on food insecurity among home owners may identify policies to mitigate recessionary outcomes. We used a before-and-after natural experimental design using data from the Canadian Community Health Survey (CCHS) cycles 2007/2008 (pre-recession) and 2009/2010 (post-recession) with information on household food insecurity, home ownership versus renting, and socio-demographics. Applying multivariable logistic regression, we examined changes in household food insecurity by housing tenure and sex over the period. Pre-recession, food insecurity affected 3.3% of home owners and 17.1% of renter households. Among home owners, the risk of food insecurity increased post-recession by 10%, which was not statistically significant. Post-recession, and with adjustment, although renters' higher absolute risk of food insecurity persisted, male-respondent home owners experienced the highest rate of increase in food insecurity prevalence by subgroup (OR = 1.26, 95% CI: 1.06-1.50) versus renters (OR = 1.17, 95% CI: 1.05-1.29). Housing policies in Canada protected most home owners from precarity during the 2008-2009 economic recession; however, male-respondent home owners exhibited a unique economic vulnerability during this time. Implications of Canadian home ownership policies are discussed in light of differential vulnerability of home owner groups.

  10. Inhibitory action of chlorophyllin of autosome recessive lethals induced by irradiation

    The chlorophyllin is a sodium salt of the chlorophyll that has a strong protective action of the damage induced by different agents so much physical as chemical. In Drosophila there is reported this effect in somatic cells. In contrast, in germinal cells using tests with the sexual chromosomes has not been found such inhibitory action. For this reason, in this occasion we will refer to the effect of the lethality induced in autosome chromosomes, in particular to the chromosome II of this species. For such effect groups of males of the line Canton-S its were pre-treated for 24h with or without 69 mm of CCS and later on treaties with or without 40 Gy of gamma irradiation. The males were then subjected to the technical Cy L / Pm for the detection of recessive lethals. In the third generation the respective counts of the descendant of each one of them to determine the corresponding categories for each extracted chromosome were made. To be mendelian crosses it is expected for a normal chromosome a proportion 2:1 of individuals with genotype Cy L / +: +/+. The absence of individuals +/+ it is indicative of a lethal gene, until 10% of these individuals of each male's total descendant, it is considered that is carrying of a semi lethal gene. The sum of lethal and semi lethals constitutes the category detrimental. The obtained results indicated that the pre-treatment with CCS reduces in a significant way the frequency of induced lethals by 40 Gy of gamma rays. The fact that an effect inhibitor has not been observed in the test of recessive lethal bound to the sex obtained previously, it contrasts with the effect observed in the chromosome II, results of this study and with the one observed in the chromosome III in somatic cells. The above-mentioned shows a differential action of the CCS between sexual chromosomes and autosomal before the effect of the gamma radiation. At the moment we don't have an explanation to these evidences. To evaluate the action of the chlorophyllin

    Slow slip events (SSEs) are observed worldwide and often coincide with tectonic tremor. Notable examples of SSEs lacking observed tectonic tremor, however, occur beneath Kīlauea Volcano, Hawaii, the Boso Peninsula, Japan, near San Juan Bautista on the San Andreas Fault, California, and recently in Central Ecuador. These SSEs are similar to other worldwide SSEs in many ways (e.g., size or duration), but lack the concurrent tectonic tremor observed elsewhere; instead, they trigger swarms of regular earthquakes. We investigate the physical conditions that may distinguish these non-tremor-genic SSEs from those associated with tectonic tremor, including slip velocity, pressure, temperature, fluids, and fault asperities, although we cannot eliminate the possibility that tectonic tremor may be obscured in highly attenuating regions. Slip velocities of SSEs at Kīlauea Volcano (∼10−6 m/s) and Boso Peninsula (∼10−7 m/s) are among the fastest SSEs worldwide. Kīlauea Volcano, the Boso Peninsula, and Central Ecuador are also among the shallowest SSEs worldwide, and thus have lower confining pressures and cooler temperatures in their respective slow slip zones. Fluids also likely contribute to tremor generation, and no corresponding zone of high vp/vs has been noted at Kīlauea or Boso. We suggest that the relatively faster slip velocities at Kīlauea Volcano and the Boso Peninsula result from specific physical conditions that may also be responsible for triggering swarms of regular earthquakes adjacent to the slow slip, while different conditions produce slower SSE velocities elsewhere and trigger tectonic tremor.

    Abnormalities of dystrophin, a cytoskeletal protein of muscle and nerve, are generally considered specific for Duchenne and Becker muscular dystrophy. However, several patients have recently been identified with dystrophin deficiency who, before dystrophin testing, were considered to have Fukuyama congenital muscular dystrophy (FCMD) on the basis of clinical findings. Epidemiologic data suggest that only 1/3,500 males with autosomal recessive FCMD should have abnormal dystrophin. To explain the observation of 3/23 FCMD males with abnormal dystrophin, the authors propose that dystrophin and the FCMD gene product interact and that the earlier onset and greater severity of these patients' phenotype (relative to Duchenne muscular dystrophy) are due to their being heterozygous for the FCMD mutation in addition to being hemizygous for Duchenne muscular dystrophy, a genotype that is predicted to occur in 1/175,000 Japanese males. This model may help explain the genetic basis for some of the clinical and pathological variability seen among patients with FCMD, and it has potential implications for understanding the inheritance of other autosomal recessive disorders in general. For example, sex ratios for rare autosomal recessive disorders caused by mutations in proteins that interact with X chromosome-linked gene products may display predictable deviation from 1:1.

  13. Genetic complexity underlying hybrid male sterility in Drosophila.

    Recent genetic analyses of closely related species of Drosophila have indicated that hybrid male sterility is the consequence of highly complex synergistic effects among multiple genes, both conspecific and heterospecific. On the contrary, much evidence suggests the presence of major genes causing hybrid female sterility and inviability in the less-related species, D. melanogaster and D. simulans. Does this contrast reflect the genetic distance between species? Or, generally, is the genetic basis of hybrid male sterility more complex than that of hybrid female sterility and inviability? To clarify this point, the D. simulans introgression of the cytological region 34D-36A to the D. melanogaster genome, which causes recessive male sterility, was dissected by recombination, deficiency, and complementation mapping. The 450-kb region between two genes, Suppressor of Hairless and snail, exhibited a strong effect on the sterility. Males are (semi-)sterile if this region of the introgression is made homozygous or hemizygous. But no genes in the region singly cause the sterility; this region has at least two genes, which in combination result in male sterility. Further, the males are less fertile when heterozygous with a larger introgression, which suggests that dominant modifiers enhance the effects of recessive genes of male sterility. Such an epistatic view, even in the less-related species, suggests that the genetic complexity is special to hybrid male sterility.

    Interdental soft tissues play a critical role in pink esthetics. The presence and preservation of the interdental papillae in the esthetic zone is as crucial as the shape and contour of the anterior teeth in achieving an esthetically pleasing smile. The present study determines the association of central papilla recession with gingival and interdental smile line in periodontally healthy patients of different age groups. The present study included 200 patients equally divided into 21 to 40 years and 41 to 60 years age groups. The clinical and photographic evaluation of the central papilla, with midfacial gingiva, and its relationship with the vermilion border was performed. In total, 137 patients exhibited presence of central papilla, whilst 63 patients had central papilla recession with variable extent. The male patients predominantly had presence of central papilla in both the age groups, with 86% and 64%, compared with 74% and 50% in females, respectively. High gingival smile line was seen in the majority of the patients (62%), and this trend was similar to high interdental smile line (82% of the patients). Esthetics is affected in individuals having papilla recession along with high gingival smile line and interdental smile line as compared to individuals with low or cupid bow gingival smile line and interdental smile line.

    The structures of the anterior epitympanic recess and its surrounding tissues were examined among non-inflammatory ear, chronic otitis media with central perforation and cholesteatoma, using axial scans of high resolution computed tomography. The length and width of the recess, as well as the number of the slices where the cog was determined, had no significant differences among them. Thus, the bony structure of the recess was considered to be seldom influenced by inflammatory processes. In the non-inflammatory ear, the degree of pneumatization around the recess was similar to that of the petrous apex cells and lower than that of the mastoid cells. In the chronic otitis media with central perforation and cholesteatoma, the pneumatization of the whole temporal bones was suppressed and the tendency was also found that the cells around the recess were less pneumatized than the mastoid cells. When cholesteatoma invaded into the anterior epitympanic recess, the destruction of the bony protrusion of the lateral wall between the recess and the epitympanum was recognized, as well as the disappearance of the cog. The bony protrusion was considered to be an inferior extention of the cog toward the anterior tympanic spine. (author)

    The breeding and large-scale adoption of hybrid seeds is an important achievement in agriculture. Rice hybrid seed production uses cytoplasmic male sterile lines or photoperiod/thermo-sensitive genic male sterile lines (PTGMS) as female parent. Cytoplasmic male sterile lines are propagated via cross-pollination by corresponding maintainer lines, whereas PTGMS lines are propagated via self-pollination under environmental conditions restoring male fertility. Despite huge successes, both systems have their intrinsic drawbacks. Here, we constructed a rice male sterility system using a nuclear gene named Oryza sativa No Pollen 1 (OsNP1). OsNP1 encodes a putative glucose-methanol-choline oxidoreductase regulating tapetum degeneration and pollen exine formation; it is specifically expressed in the tapetum and miscrospores. The osnp1 mutant plant displays normal vegetative growth but complete male sterility insensitive to environmental conditions. OsNP1 was coupled with an α-amylase gene to devitalize transgenic pollen and the red fluorescence protein (DsRed) gene to mark transgenic seed and transformed into the osnp1 mutant. Self-pollination of the transgenic plant carrying a single hemizygous transgene produced nontransgenic male sterile and transgenic fertile seeds in 1:1 ratio that can be sorted out based on the red fluorescence coded by DsRed Cross-pollination of the fertile transgenic plants to the nontransgenic male sterile plants propagated the male sterile seeds of high purity. The male sterile line was crossed with ∼1,200 individual rice germplasms available. Approximately 85% of the F1s outperformed their parents in per plant yield, and 10% out-yielded the best local cultivars, indicating that the technology is promising in hybrid rice breeding and production.

    Genic microsatellite markers, also known as functional markers, are preferred over anonymous markers as they reveal the variation in transcribed genes among individuals. In this study, we developed a total of 707 expressed sequence tag-derived simple sequence repeat markers (EST-SSRs) and used for development of a high-density integrated map using four individual mapping populations of B. rapa. This map contains a total of 1426 markers, consisting of 306 EST-SSRs, 153 intron polymorphic markers, 395 bacterial artificial chromosome-derived SSRs (BAC-SSRs), and 572 public SSRs and other markers covering a total distance of 1245.9 cM of the B. rapa genome. Analysis of allelic diversity in 24 B. rapa germplasm using 234 mapped EST-SSR markers showed amplification of 2 alleles by majority of EST-SSRs, although amplification of alleles ranging from 2 to 8 was found. Transferability analysis of 167 EST-SSRs in 35 species belonging to cultivated and wild brassica relatives showed 42.51% (Sysimprium leteum) to 100% (B. carinata, B. juncea, and B. napus) amplification. Our newly developed EST-SSRs and high-density linkage map based on highly transferable genic markers would facilitate the molecular mapping of quantitative trait loci and the positional cloning of specific genes, in addition to marker-assisted selection and comparative genomic studies of B. rapa with other related species.

    Full Text Available Purpose: This study aims to describe and compare modified hang-back recession with the conventional hang-back recession in large angle comitant exotropia (XT. Methods: A prospective, interventional, double-blinded, randomized study on adult patients (>18 years undergoing single eye recession-resection for large angle (>30 prism diopters constant comitant XT was conducted between January 2011 and December 2015. Patients in Group A underwent modified hang-back lateral rectus recession with adjustable knot while in Group B underwent conventional hang-back recession with an adjustable knot. Outcome parameters studied were readjustment rate, change in deviation at 6 weeks, complications and need for resurgery at 6 months. Results: The groups were comparable in terms of age and preoperative deviation. The patients with the modified hang back (Group A fared significantly better (P < 0.05 than those with conventional hang back (Group B in terms of lesser need for adjustment, greater correction in deviation at 6 weeks and lesser need for resurgery at 6 months. Conclusion: This modification offers several advantages, significantly reduces resurgery requirement and has no added complications.

    This study aimed to compare moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA) in normal-weight and overweight boys and girls during school recess. Four hundred twenty children, age 6 to 10 years, were randomly selected from 25 schools in England. Three hundred seventy-seven children completed the study. BMI was calculated from height and weight measurements, and heart rate reserve thresholds of 50% and 75% reflected children's engagement in MVPA and VPA, respectively. There was a significant main effect for sex and a significant interaction between BMI category and sex for the percent of recess time spent in MVPA and VPA. Normal-weight girls were the least active group, compared with overweight boys and girls who were equally active. Fifty-one boys and 24 girls of normal weight achieved the 40% threshold; of these, 30 boys and 10 girls exceeded 50% of recess time in MVPA. Eighteen overweight boys and 22 overweight girls exceeded the 40% threshold, whereas 8 boys and 8 girls exceeded the 50% threshold. Overweight boys were significantly less active than their normal-weight male counterparts; this difference did not hold true for girls. Even though nearly double the number of normal-weight children achieved the 40% of MVPA during recess compared with overweight children, physical activity promotion in school playgrounds needs to be targeted not only at overweight but at other health parameters, as 40 overweight children met the 40% MVPA target proposed for recess.

    In this cross-sectional study, risk and potentially causative factors of gingival recession were examined and their relationship to apical migration of the gingival margin evaluated. Thirty eight patients (18-60 years), displaying one or more sites with gingival recession but without any significant periodontal disease participated. A total of 28 parameters were evaluated in both 'test' teeth (50 teeth with gingival recession) and 'control' teeth (50 contralateral teeth). The results revealed that gingival margin recession was associated with both high inflammatory and plaque scores, with decreased widths of keratinized and attached gingiva and with the subjects' toothbrush bristle hardness.

    Streamflow recession curves are hydrological signatures allowing to study the relationship between groundwater storage and baseflow and/or low flows at the catchment scale. Recent studies have showed that streamflow recession analysis can be quite sensitive to the combination of different models, extraction techniques and parameter estimation methods. In order to better characterize streamflow recession curves, new methodologies combining multiple approaches have been recommended. The HYDRORECESSION toolbox, presented here, is a Matlab graphical user interface developed to analyse streamflow recession time series with the support of different tools allowing to parameterize linear and nonlinear storage-outflow relationships through four of the most useful recession models (Maillet, Boussinesq, Coutagne and Wittenberg). The toolbox includes four parameter-fitting techniques (linear regression, lower envelope, data binning and mean squared error) and three different methods to extract hydrograph recessions segments (Vogel, Brutsaert and Aksoy). In addition, the toolbox has a module that separates the baseflow component from the observed hydrograph using the inverse reservoir algorithm. Potential applications provided by HYDRORECESSION include model parameter analysis, hydrological regionalization and classification, baseflow index estimates, catchment-scale recharge and low-flows modelling, among others. HYDRORECESSION is freely available for non-commercial and academic purposes.

  3. Performance Analysis of High-Speed Deep/Shallow Recessed Hybrid Bearing

    2013-01-01

    Full Text Available The present paper proposes a theoretical analysis of the performance of deep/shallow recessed hybrid bearing. It is intended that, on the basis of the numerical results drawn from this study, appropriate shallow recess depth and width can be determined for use in the bearing design process. By adopting bulk flow theory, the turbulent Reynolds equation and energy equation are modified and solved numerically including concentrated inertia effects at the recess edge with different depth and width of shallow recess. The results indicate that the load capacity, drag torque increases as the depth of shallow recess is shallower and the width ratio (half angle of deep recess versus half angle of shallow recess is smaller. In contrast, the flow rate decreases as the depth of shallow recess is shallower and the width ratio is smaller. Nevertheless, the appropriate design of the depth and width of shallow recess might well induce the performance of high-speed deep/shallow recessed hybrid bearing.

    Full Text Available AIM: Literature is replete with studies on gingival recession, the apical shift of the gingival margin from the cemento-enamel junction. Chronic periodontitis and frequent toothbrushing are among its aetiological factors. Many of these were however prevalence studies. The current study was therefore aimed at separating prognostic indicators from determinants of the number of recessions. METHOD: 650 consecutive adult patients visiting a Nigerian teaching hospital were examined using a checklist including plaque, calculus, Miller’s class of recession and other parameters.. A total of 408 recession sites were identified. RESULTS: The mean age of the patients with recession was 42.3 years; mean number of recession was 4.74 Incisors had the highest number of recessions (35.7%. While a factor such as age was related both to the number and prognosis of recession sites, abrasion and plaque were only related to prognosis. Again, some of the factors previously significantly related to prognosis on univariate analysis like calculus and smoking, lost their significance on regression analysis. CONCLUSION: The three strongest predictors of prognosis (Miller’s class of recession were age, plaque and abrasion. [TAF Prev Med Bull 2010; 9(3.000: 187-194

    The present-day stage of industrial advance is associated with a risk of occurrence of anomalous and catastrophic natural and techno-genic events. The process of hydrocarbon field development can result in adverse consequences for the interior of the earth and for the environment in general. Two factors that complement and intensify each other can be conducive to that: the natural factor (geodynamic conditions) and the techno-genic factor (engineering and technological solutions employed for the development of formations). The lithosphere undergoes current geodynamic processes of high activity. Tectonic flexure faults bring about leakage from the wells and from the reservoirs in the process of fluid withdrawal. Man changes inevitably the interior of the earth and, as a consequence, the face of the planet while producing significant volumes of oil, gas and water. It is necessary to minimize the damage from penetration into the earth required to find very much needed energy. Negative after-effects are examined, in particular rock subsidence, failure of well casing strings, hydrodynamic changes in gas-bearing formations, techno-genic and induced earthquakes, etc. Cited are methods to reduce the after-effects that have already been worked out. It is emphasized that there is a need in registering and forecasting the environmental consequences of the natural and techno-genic events. (authors)

    The Great Recession of 2007-2009 was the most severe and lengthy economic crisis in the U.S. since the Great Depression. The impacts on the population were multi-dimensional, but operated largely through local labor markets. To examine differences in recession-related changes in county unemployment rates and assess how population and place characteristics shaped these patterns. We calculate and decompose Theil Indexes to describe recession-related changes in the distribution of unemployment rates between counties and states. We use exploratory spatial statistics to identify geographic clusters of counties that experienced similar changes in unemployment. We use spatial regression to evaluate associations between county-level recession impacts on unemployment and demographic composition, industrial structure, and state context. The recession was associated with increased inequality between county labor markets within states, but declining between-state differences. Counties that experienced disproportionate recession-related increases in unemployment were spatially clustered and characterized by large shares of historically disadvantaged racial and ethnic minority populations, low educational attainment, and heavy reliance on pro-cyclical industries. Associations between these sources of vulnerability were partially explained by unobserved state-level factors. The local consequences of macroeconomic trends are associated with county population characteristics, as well as the structural contexts and policy environments in which they are embedded. The recession placed upward pressure on within-state inequality between local labor market conditions. To present new estimates of the recession's impact on local labor markets, quantify how heterogeneous impacts affected the distribution of unemployment prevalence, and identify county characteristics associated with disproportionately large recession-related increases in unemployment.

    Dystrophic epidermolysis bullosa is a rare inherited disease caused by mutations in the COL7A1 gene. Its recessive variant (recessive dystrophic epidermolysis bullosa) is characterized by the absence or considerably reduced expression of type VII collagen, which leads to marked fragility of the skin and mucous membranes and subsequent blister formation, whether spontaneously or following minimal injury. There have been very few reports of this disease in pregnant women. We present 2 cases of pregnant women with recessive dystrophic epidermolysis bullosa managed in our High-Risk Pregnancy Unit at Hospital Universitario La Paz, Madrid, Spain. Both patients underwent full-term cesarean delivery, with no further complications for mother or child. Although recessive dystrophic epidermolysis bullosa increases the risk of maternal complications, a patient is not advised against pregnancy. With adequate monitoring, these patients can fulfil their desire to become mothers. Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    1988-06-01

    Data for nondifferentially stained chromosomes from 10 species of Rhinolophus (Chiroptera: Rhinolophidae) suggest a conserved chromosomal evolution. G-banded chromosomes for three well differentiated species (Rhinolophus hipposideros, Rhinolophus blasii, and Rhinolophus acuminatus) corroborate a low level of gross chromosomal rearrangements. Additionally, a comparison between G-banded chromosomes of Rhinolophus (Rhinolophidae) and Hipposideros (Hipposideridae) suggests extreme conservatism in chromosomal arms between these two distantly related groups. On the other hand, we report extensive genic divergence as assayed by starch gel electrophoresis among these 10 species, and between Rhinolophus and two hipposiderid genera (Hipposideros and Aselliscus). The present chromosomal data are not sufficient for phylogenetic analysis. Phylogenies based on electrophoretic data are in many aspects discordant with those based on the classical morphological criteria. Different (and as yet not clearly understood) evolutionary forces affecting chromosomal, morphologic, and electrophoretic variation may be the reason for the apparent lack of concordance in these independent data sets.

    Full Text Available Objective: The aim of this study was to investigate the genetic causes of autosomal recessive intellectual disabilities (AR-ID in Hamadan province of Iran. Materials & Methods: In this descriptive-analytical cross-sectional study, 25 families with more than one affected with putative autosomal recessive intellectual disability were chosen with collaboration of Welfare Organization of Hamadan province. Families were included a total of 60 patients (39 male and 21 female whose intellectual disability had been confirmed by Raven IQ test. Each family was asked for clinical examination and getting consent form. Blood sample was collected from each family. One proband from each family was tested for CGG repeat expansion in FMR1 gene, chromosomal abnormalities and inborn errors of metabolism. We also performed homozygosity mapping based on STR markers for seven known MCPH loci in families with primary microcephaly and AR-ID. Results: Five families had full mutation of Fragile X syndrome. No chromosomal abnormalities were identified. Metabolic screening revealed one family with Medium Chain Acyl CoA Dehydrogenase deficiency. None of three families with primary microcephaly and AR-ID showed linkage to any of known seven MCPH loci. Conclusion: The main causes of ID in Hamadan province were Fragile X syndrome and Autosomal Recessive Primary Microcephaly with the frequencies of 20% and 12%, respectively.

    The Great Recession's influence on American undergraduate students' values was examined, testing Greenfield's and Kasser's theories concerning value development during economic downturns. Study 1 utilised aggregate-level data to investigate (a) population-level value changes between the pre-recession (2004-2006: n = 824,603) and recession freshman cohort (2008-2010: n = 662,262) and (b) overall associations of population-level values with national economic climates over long-term periods by correlating unemployment rates and concurrent aggregate-level values across 1966-2015 (n = 10 million). Study 2 examined individual-level longitudinal value development from freshman to senior year, and whether the developmental trajectories differed between those who completed undergraduate education before the Great Recession (freshmen in 2002, n = 12,792) versus those who encountered the Great Recession during undergraduate years (freshmen in 2006, n = 13,358). Results suggest American undergraduate students' increased communitarianism (supporting Greenfield) and materialism (supporting Kasser) during the Great Recession. The recession also appears to have slowed university students' development of positive self-views. Results contribute to the limited literature on the Great Recession's influence on young people's values. They also offer theoretical and practical implications, as values of this privileged group of young adults are important shapers of societal values, decisions, and policies. © 2016 International Union of Psychological Science.

    2018-03-01

    During a recession, cost-sharing of employer-sponsored health benefits could increase to reduce labor costs in the U.S. Using a variation in the severity of recession shocks across industries, I find evidence that the enrollment rate of high deductible health plans (HDHPs) among workers covered by employer-sponsored health benefits increased more among firms in industries that experienced severe recession shocks. As potential mechanisms, I study employer-side and worker-side mechanisms. I find that employers changed health benefit offerings to force or incentivize workers to enroll in HDHPs. But I find little evidence of an increase in workers' demand for HDHPs due to a reduction in income. These results suggest that the HDHP enrollment rate increased during the Great Recession, as employers tried to save costs of offering health benefits. Copyright © 2018 Elsevier B.V.

  17. Measurement of the lateral recess angle as a possible alternative for evaluation of the lateral recess stenosis on a CT scan

    International Nuclear Information System (INIS)

    Strojnik, T.

    2001-01-01

    Stenosis of the lateral recess in the lumbar spinal canal is a clinical problem, especially in terms of surgical management. Criteria for the diagnosis and surgical treatment of lateral recess stenosis (LRS) are not clearly defined. Several authors have suggested measurement of the lateral recess height (LRH) on computed tomography (CT) scans as a helpful tool for making decisions in regard of management. The present study is based an the assumption that measurement of the lateral recess angle (LRA) may be useful in the clinical management of lateral recess stenosis. The reliability and significance of the results have been analyzed. In 35 patients, the stenosis was confirmed by intraoperative measurement of the lateral recess height. Fifty-three affected lateral recesses were analyzed. Before surgery, the heights on CT scans were measured. The mean value was 3.3 mm (SD = 0.9 mm), while 41 of them were 3.6 mm or less. Furthermore, the angles on CT scans were evaluated. The mean value was 25.9 degrees (SD = 4.9 degrees), 48 of them were 30 degrees or less and only 5 of them achieved more than 30 degrees. Results reveal that the best quantitative determination of a lateral recess stenosis is a CT scan angle measurement with a critical value of 30 degrees. A CT scan height of 3.6 mm or less is also indicative of stenosis. Statistical evaluation of the data by multiple regression analysis revealed agreement between intraoperative findings and measured heights (p = 0.02), while even better results were noted for angles (p < 0.01). Interfacet distance (IF) was found to be least predictive (p = 0.04). (author)

This is an ecological study in which MEDLINE, PsycINFO and PubMed were searched for the literature with combinations of the following keywords: economic recession, financial crisis, unemployment, health, suicide and mental health. Data from two Italian government agencies (Italian Institute of Statistics, ISTAT, and Italian Agency of Drugs, AIFA) in the years from 2000 to 2010 were obtained and analysed, by producing models of multiple linear regressions. After the recession onset, all-cause mortality remained stable, and was not associated with the economic fluctuations. Differently, cardiovascular mortality was associated with the rate of unemployment, and showed a significant increase in 2010. Alcohol consumption increased in 2009, the year with the worst real GDP decrease (-5.1 %). Though the total rate of suicide was not associated with the economic situation, male completed and attempted suicides due to financial crisis were significantly associated with the rate of unemployment and the real GDP. The increasing diffusion of antidepressants was not associated with a lowering of the rate of suicide. The data on the Italian situation here discussed are sufficiently reliable to conclude that a link exists between the ongoing economic recession and health and mental health of Italians. Further research is needed to understand more in detail and with stronger reliability such link, to support primary and secondary preventive interventions and orient the development of effective sociopolitical interventions.

    Hospital capital investment is important for acquiring and maintaining technology and equipment needed to provide health care. Reduction in capital investment by a hospital has negative implications for patient outcomes. Most hospitals rely on debt and internal cash flow to fund capital investment. The great recession may have made it difficult for hospitals to borrow, thus reducing their capital investment. I investigated the impact of the great recession on capital investment made by California hospitals. Modeling how hospital capital investment may have been liquidity constrained during the recession is a novel contribution to the literature. I estimated the model with California Office of Statewide Health Planning and Development data and system generalized method of moments. Findings suggest that not-for-profit and public hospitals were liquidity constrained during the recession. Comparing the changes in hospital capital investment between 2006 and 2009 showed that hospitals used cash flow to increase capital investment by $2.45 million, other things equal.

    Nucleosomal organization in and around genes may contribute substantially to transcriptional regulation. The contribution of histone modifications to genome-wide nucleosomal organization has not been systematically evaluated. In the present study, we examine the role of H2BK123 ubiquitylation, a key regulator of several histone modifications, on nucleosomal organization at promoter, genic, and transcription termination regions in Saccharomyces cerevisiae. Using high-resolution MNase chromatin immunoprecipitation and sequencing (ChIP-seq), we map nucleosome positioning and occupancy in mutants of the H2BK123 ubiquitylation pathway. We found that H2B ubiquitylation-mediated nucleosome formation and/or stability inhibits the assembly of the transcription machinery at normally quiescent promoters, whereas ubiquitylation within highly active gene bodies promotes transcription elongation. This regulation does not proceed through ubiquitylation-regulated histone marks at H3K4, K36, and K79. Our findings suggest that mechanistically similar functions of H2B ubiquitylation (nucleosome assembly) elicit different functional outcomes on genes depending on its positional context in promoters (repressive) versus transcribed regions (activating).

    According to the literature, accommodative esotropia has an unpredictable course when nonsurgical treatment is considered, especially in cases with a high accommodative convergence/accommodation ratio (AC/A). The aim of this study was to compare the results of augmented recession, slanted recession, and recession with posterior fixation suture of the medial rectus muscles in the treatment of high AC/A esotropia. Twenty-eight children (4 to 14 years old) with high AC/A esotropia with a near-distance disparity greater than 10 PD were included in a prospective, randomized, blinded clinical trial. Nine children underwent recession of both medial rectus muscles and posterior fixation suture (Faden procedure), 9 children underwent augmented recession of the medial rectus muscles, and 10 children underwent slanted recession of both medial rectus muscles. The amount of esodeviation was measured before strabismus surgery and at least 6 months postoperatively. In the augmented recession group, the mean near-distance disparity was reduced from 16.33 +/- 2.17 PD preoperatively to 7.55 +/- 3.87 PD postoperatively (54.21%; P = .056). In the Faden procedure group, it was reduced from 15.22 +/- 4.08 PD to 2.55 +/- 4.03 PD (80.7%; P = .056). In the slanted recession group, it was reduced from 15.50 +/- 4.30 PD to 4.10 +/- 4.80 PD (67.55%; P = .056). The Faden procedure had the best outcome, but slanted recession also was successful. Because of our good results and an easy, non-invasive approach without any additional complications, we recommend slanted recession to treat high AC/A esotropia.

    The "Great Recession" lasted from December 2007 to June 2009, and it wreaked havoc on the revenues of state (and local) governments. While the U.S. economy has improved since the end of the Great Recession, state government revenues have in most cases still not completely recovered. We use various indicators to measure how different states have -- or have not -- recovered in the aftermath of the Great Recession, and we also attempt to explain why these different patterns of recovery have emer...

    Full Text Available Groundwater has received increasing attention as an important strategic water resource for adaptation to climate change. In this regard, the separation of baseflow from streamflow and the analysis of recession curves make a significant contribution to integrated river basin management. The United States Geological Survey (USGS RECESS model adopting the master-recession curve (MRC method can enhance the accuracy with which baseflow may be separated from streamflow, compared to other baseflow-separation schemes that are more limited in their ability to reflect various watershed/aquifer characteristics. The RECESS model has been widely used for the analysis of hydrographs, but the applications using RECESS were only available through Microsoft-Disk Operating System (MS-DOS. Thus, this study aims to develop a web-based RECESS model for easy separation of baseflow from streamflow, with easy applications for ungauged regions. RECESS on the web derived the alpha factor, which is a baseflow recession constant in the Soil Water Assessment Tool (SWAT, and this variable was provided to SWAT as the input. The results showed that the alpha factor estimated from the web-based RECESS model improved the predictions of streamflow and recession. Furthermore, these findings showed that the baseflow characteristics of the ungauged watersheds were influenced by the land use and slope angle of watersheds, as well as by precipitation and streamflow.

    Background The Great Recession of 2007–2009 was the most severe and lengthy economic crisis in the U.S. since the Great Depression. The impacts on the population were multi-dimensional, but operated largely through local labor markets. Objective To examine differences in recession-related changes in county unemployment rates and assess how population and place characteristics shaped these patterns. Methods We calculate and decompose Theil Indexes to describe recession-related changes in the distribution of unemployment rates between counties and states. We use exploratory spatial statistics to identify geographic clusters of counties that experienced similar changes in unemployment. We use spatial regression to evaluate associations between county-level recession impacts on unemployment and demographic composition, industrial structure, and state context. Results The recession was associated with increased inequality between county labor markets within states, but declining between-state differences. Counties that experienced disproportionate recession-related increases in unemployment were spatially clustered and characterized by large shares of historically disadvantaged racial and ethnic minority populations, low educational attainment, and heavy reliance on pro-cyclical industries. Associations between these sources of vulnerability were partially explained by unobserved state-level factors. Conclusions The local consequences of macroeconomic trends are associated with county population characteristics, as well as the structural contexts and policy environments in which they are embedded. The recession placed upward pressure on within-state inequality between local labor market conditions. Contribution To present new estimates of the recession’s impact on local labor markets, quantify how heterogeneous impacts affected the distribution of unemployment prevalence, and identify county characteristics associated with disproportionately large recession

  8. Effects of combined gate and ohmic recess on GaN HEMTs

    Full Text Available AlGaN/GaN, because of their superior material properties, are most suitable semiconductor material for High Electron Mobility Transistors (HEMTs. In this work we investigated the hidden physics behind these materials and studied the effect of recess technology in AlGaN/GaN HEMTs. The device under investigation is simulated for different recess depth using Silvaco-Atlas TCAD. Recess technology improves the performance of AlGaN/GaN HEMTs. We considered three kinds of recess technology gate, ohmic and combination of gate and ohmic. Gate recess improves transconductance gm but it reduces the drain current Id of the device under investigation. Ohmic recess improves the transconductance gm but it introduces leakage current Ig in the device. In order to use AlGaN/GaN for high voltage operation, both the transconductance and the drain current should be reasonably high which is obtained by combining both gate and ohmic recess technologies. A good balance in transconductance and drain current is achieved by combining both gate and ohmic recess technologies without any leakage current.

    2010-03-01

    Postzygotic reproductive isolation evolves when hybrid incompatibilities accumulate between diverging populations. Here, I examine the genetic basis of hybrid male sterility between two species of Drosophila, Drosophila virilis and D. americana. From these analyses, I reach several conclusions. First, neither species carries any autosomal dominant hybrid male sterility alleles: reciprocal F(1) hybrid males are perfectly fertile. Second, later generation (backcross and F(2)) hybrid male sterility between D. virilis and D. americana is not polygenic. In fact, I identified only three genetically independent incompatibilities that cause hybrid male sterility. Remarkably, each of these incompatibilities involves the Y chromosome. In one direction of the cross, the D. americana Y is incompatible with recessive D. virilis alleles at loci on chromosomes 2 and 5. In the other direction, the D. virilis Y chromosome causes hybrid male sterility in combination with recessive D. americana alleles at a single QTL on chromosome 5. Finally, in contrast with findings from other Drosophila species pairs, the X chromosome has only a modest effect on hybrid male sterility between D. virilis and D. americana.

    Inheritance and main agronomic traits of photo-thermo-sensitive genic male sterile line with green-revertible albino leaf were investigated. The results indicated that the mutants might be divided into three types: albino regreening type (W2, W3, W4 and W10), albino to kelly type (W9) and abino-regreening-albino-regreening type (W1 and W7). Genetic study indicated that green-revertible albino leaf color trait of the mutants as controlled by a single recessive gene. These mutants had similar agronomic traits and fertility characteristics to the corresponding male sterile line 'Peiai 64S'. The hybrids of these mutants had similar characteristics with original-hybrids in plant type, developing of tillers and plant height. The yield components of the mutant hybrids were different depending on different mutants. The yield potential of hybrids of W1, W2 and W3 were similar to the original-hybrid. The results also indicated that W1, W2 and W3 had breeding application value. (authors)

    The present investigation was carried out aiming to use the bioinformatics tools in order to identify and characterize, simple sequence repeats within the third Version of the date palm genome and develop a new SSR primers database. In addition single nucleotide polymorphisms (SNPs) that are located within the SSR flanking regions were recognized. Moreover, the pathways for the sequences assigned by SSR primers, the biological functions and gene interaction were determined. A total of 172,075 SSR motifs was identified on date palm genome sequence with a frequency of 450.97 SSRs per Mb. Out of these, 130,014 SSRs (75.6%) were located within the intergenic regions with a frequency of 499 SSRs per Mb. While, only 42,061 SSRs (24.4%) were located within the genic regions with a frequency of 347.5 SSRs per Mb. A total of 111,403 of SSR primer pairs were designed, that represents 291.9 SSR primers per Mb. Out of the 111,403, only 31,380 SSR primers were in the genic regions, while 80,023 primers were in the intergenic regions. A number of 250,507 SNPs were recognized in 84,172 SSR flanking regions, which represents 75.55% of the total SSR flanking regions. Out of 12,274 genes only 463 genes comprising 896 SSR primers were mapped onto 111 pathways using KEGG data base. The most abundant enzymes were identified in the pathway related to the biosynthesis of antibiotics. We tested 1031 SSR primers using both publicly available date palm genome sequences as templates in the in silico PCR reactions. Concerning in vitro validation, 31 SSR primers among those used in the in silico PCR were synthesized and tested for their ability to detect polymorphism among six Egyptian date palm cultivars. All tested primers have successfully amplified products, but only 18 primers detected polymorphic amplicons among the studied date palm cultivars.

    The severity, sudden onset, and multipronged nature of the Great Recession (2007-2009) provided a unique opportunity to examine the health impacts of macroeconomic downturn. We comprehensively review empirical literature examining the relationship between the Recession and mental and physical health outcomes in developed nations. Overall, studies reported detrimental impacts of the Recession on health, particularly mental health. Macro- and individual-level employment- and housing-related sequelae of the Recession were associated with declining fertility and self-rated health, and increasing morbidity, psychological distress, and suicide, although traffic fatalities and population-level alcohol consumption declined. Health impacts were stronger among men and racial/ethnic minorities. Importantly, strong social safety nets in some European countries appear to have buffered those populations from negative health effects. This literature, however, still faces multiple methodological challenges, and more time may be needed to observe the Recession's full health impact. We conclude with suggestions for future work in this field.

    The general focus of this aerodynamic noise research, induced by turbulent incompressible flow, is to improve our knowledge of acoustic production mechanisms in the TGV pantograph recess in order to be able to reduce the radiated noise. This work is performed under contract with SNCF as a part of the German-French Cooperation DEUFRAKO K2, and is supported by French Ministries for Transport and Research. Previous studies on TGV noise source locations (DEUFRAKO K) have identified the pantograph recess as one of the important aerodynamic noise sources, for speeds higher than 300 km/h, due to flow separation. The pantograph recess is a very complex rectangular cavity, located both on the power car and the first coach roofs of the TGV, and has not been studied before due to the complex shapes. Its aeroacoustic features are investigated experimentally in a low-subsonic wind tunnel, on a realistic 1/7th scale mock-up both with and without pantographs. Flow velocities, estimated with hot-wire anemometry, and parietal visualizations show the flow to reattach on the recess bottom wall and to separate again at the downstream face. Wall pressure fluctuations and “acoustic” measurements using 14 and 12 in microphones respectively are also measured to qualify the flow: no aerodynamic or acoustic oscillations are observed. The study indicates that the pantograph recess has a different behaviour compared to the usual cavity grazing flows.

    With the rapid increase in obesity rates among youth, efforts to increase physical activity (PA) have become a priority. School-based strategies for PA promotion must be cost-effective, unobtrusive, and linked to improved academic performance. Efforts to maximize recess PA are advocated because of both health and academic benefits. The purpose of this manuscript was to review recess interventions aimed to improve PA among youth, and make recommendations to develop related best practices. An extensive literature search was conducted to include all primary research articles evaluating any recess intervention with PA as an outcome. The included 13 interventions represented both settings within the U.S and internationally, among preschools and elementary/primary schools. A variety of strategies were used within the design and implementation of each of the interventions including: added equipment/materials, markings, zones, teacher involvement, active video games, activity of the week, and activity cards. Of the included studies, 95% demonstrated positive outcomes as a result of the recess intervention. A number of simple, low-cost strategies can be implemented to maximize the amount of recess time students are allotted. Long-term follow-up studies are warranted for each of the recess strategies identified to be effective.

Methods: PA was measured via accelerometers in preschool-aged children (n = 29 during three, 30-min recess conditions (control; structured play; free play on separate school days. Tertile splits were performed based on PA during the free play condition and children were divided into three groups: highly, moderately and least active. Results: For the aggregated sample, children were more (p ≤ 0.001 active during the free play (1282 ± 662 counts. min−1 and structured play (1416 ± 448 counts. min−1 recess versus the control condition (570 ± 460 counts. min−1 and activity was not different between the free play and structured conditions. However, children who were the most active during free play (1970 ± 647 counts·min−1 decreased (p ≤ 0.05 activity during structured play (1462 ± 535 counts·min−1, whereas children who were moderately active (1031 ± 112 counts·min−1 or the least (530 ± 239 counts·min−1 active during free play increased activity during structured play (1383 ± 345 counts·min−1 moderately active, 1313 ± 413 counts·min−1 least active. Conclusion: Providing a physically-active recess period will contribute to preschool-aged children meeting the recommended PA guidelines; however, different children may respond in a different way based upon the structure of the recess period.

    Very few studies describe the clinical results and complications following the surgical procedure of gastrocnemius recession. To survey the patient reported outcomes in patients operated with gastrocnemius recession as single procedure for various foot conditions. 93 patients operated with gastrocnemius recession as single procedure between 2006 and 2011 were detected in the database. 73 patients responded to the invitation for study participation. Questionnaires containing patient reported satisfaction, complications, plantar flexion power and visual analog pain score were used for evaluation of the postoperative result. 45/73 (62%) patients reported a good or excellent result. 8/73 (11%) patients reported a significant postoperative complication. 16/73 (22%) patients noted reduced or severely reduced plantar flexion power after surgery. VAS pain score significantly decreased from 7.0 before surgery to 1.8 (p=0.015) after surgery for patients with plantar fasciitis (n=18) and from 5.6 to 2.3 (p<0.01) for patients with metatarsalgia (n=28). Patients treated with gastrocnemius recession for plantar fasciitis demonstrated good clinical results. The complication rate was higher than reported by others.

    Full Text Available Abstract Background Photoperiod-sensitive genic male sterile (PGMS rice, Nongken 58S, was discovered in 1973. It has been widely used for the production of hybrid rice, and great achievements have been made in improving rice yields. However, the mechanism of the male sterility transition in PGMS rice remains to be determined. Results To investigate the transcriptome during the male sterility transition in PGMS rice, the transcriptome of Nongken 58S under short-day (SD and long-day (LD at the glume primordium differentiation and pistil/stamen primordium forming stages was compared. Seventy-three and 128 differentially expressed genes (DEGs were identified at the glume primordium differentiation and pistil/stamen primordium forming stages, respectively. Five and 22 genes were markedly up-regulated (≥ 5-fold, and two and five genes were considerably down-regulated (≥ 5-fold under SD during the male sterility transition. Gene ontology annotation and pathway analysis revealed that four biological processes and the circadian rhythms and the flowering pathways coordinately regulated the male sterility transition. Further quantitative PCR analysis demonstrated that the circadian rhythms of OsPRR1, OsPRR37, OsGI, Hd1, OsLHY and OsDof in leaves were obviously different between Nongken 58S and Nongken 58 under LD conditions. Moreover, both OsPRR37 and Hd1 in the inflorescence displayed differences between Nongken 58S and Nongken 58 under both LD and SD conditions. Conclusion The results presented here indicate that the transcriptome in Nongken 58S was significantly suppressed under LD conditions. Among these DEGs, the circadian rhythm and the flowering pathway were involved in the male sterility transition. Furthermore, these pathways were coordinately involved in the male sterility transition in PGMS rice.

  4. Patterns of genic diversity and structure in a species undergoing rapid chromosomal radiation: an allozyme analysis of house mice from the Madeira archipelago.

    The chromosomal radiation of the house mouse in the island of Madeira most likely involved a human-mediated colonization event followed by within-island geographical isolation and recurrent episodes of genetic drift. The genetic signature of such processes was assessed by an allozyme analysis of the chromosomal races from Madeira. No trace of a decrease in diversity was observed suggesting the possibility of large founder or bottleneck sizes, multiple introductions and/or a high post-colonization expansion rate. The Madeira populations were more closely related to those of Portugal than to other continental regions, in agreement with the documented human colonization of the island. Such a Portuguese origin contrasts with a study indicating a north European source of the mitochondrial haplotypes present in the Madeira mice. This apparent discrepancy may be resolved if not one but two colonization events took place, an initial north European introduction followed by a later one from Portugal. Asymmetrical reproduction between these mice would have resulted in a maternal north European signature with a nuclear Portuguese genome. The extensive chromosomal divergence of the races in Madeira is expected to contribute to their genic divergence. However, there was no significant correlation between chromosomal and allozyme distances. This low apparent chromosomal impact on genic differentiation may be related to the short time since the onset of karyotypic divergence, as the strength of the chromosomal barrier will become significant only at later stages.

    The aim of the current research was to assess the prevalence of gingival recession and to investigate possible associations among this condition, periodontal and epidemiological variables in a sample of young Greek adults in a general dental practice. A total of 1,430 young adults was examined clinically and interviewed regarding several periodontal and epidemiological variables. Collected data included demographic variables, oral hygiene habits and smoking status. Clinical examination included the recording of dental plaque, supragingival calculus presence, gingival status and buccal gingival recession. Multivariate logistic regression analysis model was performed to access the possible association between gingival recession and several periodontal and epidemiological variables as potential risk factors. The overall prevalence of gingival recession was 63.9%. The statistical analysis indicated that higher educational level [OR= 2.12, 95% CI= 0.53-8.51], cigarette smoking [OR= 1.97, 95% CI= 1.48-7.91], frequent tooth brushing [OR= 0.98, 95% CI= 0.56-1.96], presence of oral piercing [OR= 0.92, 95% CI= 0.38-1.58], presence of gingival inflammation [OR= 4.54, 95% CI= 1.68-7.16], presence of dental plaque [OR= 1.67, 95% CI= 0.68-2.83] and presence of supragingival calculus [OR=1.34, 95% CI= 0.59-1.88], were the most important associated factors of gingival recession. The observations of the current research supported the results from previous authors that several periodontal factors, educational level and smoking were significantly associated with the presence of gingival recession, while presence of oral piercing was a new factor that was found to be associated with gingival recession. Key words:Gingival recession, prevalence, risk factors, young adults.

    Smoking is a major risk factor for destructive periodontal disease. There is limited information with regard to effects of smoking in subjects with minimal periodontal destruction. The aim of the present investigation was to assess the development of gingival recession in young adult smokers and non-smokers. 61 systemically healthy young adults, 19 to 30 years of age completed the final examination. 30 volunteers smoked at least 20 cigarettes per day, whereas 31 subjects were non-smokers. Clinical periodontal conditions were assessed 4x within a time period of 6 months. Site-specific analyses considering the correlated structure of data were performed. At the outset, 50% of subjects presented with gingival recession at 1 or more sites. There was no significant difference in the prevalence of gingival recession between non-smokers and smokers. Severe recession in excess of 2 mm affected about 23% non-smokers but only 7% smokers. Some further gingival recession developed during the 6-month observation period. In a multivariate logistic regression analysis, the risk for recession development appeared not to be influenced by smoking status after adjusting for periodontal probing depth, recession at baseline, tooth brushing frequency, gender, jaw, tooth type and site. Present data did not support the hypothesis that smokers are at an increased risk for the development of gingival recession.

    Autosomal recessive polycystic kidney disease is a truly catastrophic monogenetic disease, causing death and end stage renal disease in neonates and children. Using PCK female rats, an orthologous model of autosomal recessive polycystic kidney disease harboring mutant Pkhd1, we tested the hypothesis that intravenous renal cell transplantation with normal Sprague Dawley male kidney cells would improve the polycystic kidney disease phenotype. Cytotherapy with renal cells expressing wild type Pkhd1 and tubulogenic serum amyloid A1 had powerful and sustained beneficial effects on renal function and structure in the polycystic kidney disease model. Donor cell engraftment and both mutant and wild type Pkhd1 were found in treated but not control PCK kidneys 15 weeks after the final cell infusion. To examine the mechanisms of global protection with a small number of transplanted cells, we tested the hypothesis that exosomes derived from normal Sprague Dawley cells can limit the cystic phenotype of PCK recipient cells. We found that renal exosomes originating from normal Sprague Dawley cells carried and transferred wild type Pkhd1 mRNA to PCK cells in vivo and in vitro and restricted cyst formation by cultured PCK cells. The results indicate that transplantation with renal cells containing wild type Pkhd1 improves renal structure and function in autosomal recessive polycystic kidney disease and may provide an intra-renal supply of normal Pkhd1 mRNA.

  9. Pattern of Glacier Recession in Indian Himalaya

    Singh, Ajay; Patwardhan, Anand

    All currently available climate models predict a near-surface warming trend under the influence of rising levels of greenhouse gases in the atmosphere. In addition to the direct effects on climate — for example, on the frequency of heat waves — this increase in surface temperatures has important consequences for the cryosphere subsequently hydrological cycle, particularly in regions where water supply is currently dominated by melting snow or ice. The Indian Himalayan region occupies a special place in the mountain ecosystems of the world. These geodynamically young mountains are not only important from the standpoint of climate and as a provider of life, giving water to a large part of the Indian subcontinent, but they also harbor a rich variety of flora, fauna, human communities and cultural diversity. Glaciers in this region are changing in area as well as in volume like those in other parts of the world. Studies have been carried out for recession in some of these glaciers using remote sensing as well as field observation techniques. Spatiotemporal pattern in the recession rate of the studied glaciers has been presented in this paper. Plausible causes for the recession have been also discussed. Finally, future scopes for observation and analysis in glaciers recession have been suggested.

    Eleven male-sterile mutants were induced from a rice variety Sasanishiki by ethyleneimine and γ-ray treatments of seeds. Nine of them produced no pollen grains or only abortive ones and the other two showed extremely low pollen fertilities. The eleven mutants were crossed with the original variety. All F 1 hybrids were fertile, i.e., normal in both pollen and seed fertilities. In eight of their F 2 progenies, fertile and male-sterile plants segregated in a ratio of 3 to 1, indicating that the male sterility of the eight mutants was controlled by a single recessive gene. In one of the other three, segregation ratio suggested the participation of two recessive genes, while in the remaining two, the number of the genes responsible for male sterility could not be determined.

  11. Stream recession curves and storage variability in small watersheds

    2011-07-01

    Full Text Available The pattern of streamflow recession after rain events offers clues about the relationship between watershed runoff (observable as river discharge and water storage (not directly observable and can help in water resource assessment and prediction. However, there have been few systematic assessments of how streamflow recession varies across flow rates and how it relates to independent assessments of terrestrial water storage. We characterized the streamflow recession pattern in 61 relatively undisturbed small watersheds (1–100 km2 across the coterminous United States with multiyear records of hourly streamflow from automated gauges. We used the North American Regional Reanalysis to help identify periods where precipitation, snowmelt, and evaporation were small compared to streamflow. The order of magnitude of the recession timescale increases from 1 day at high flow rates (~1 mm h−1 to 10 days at low flow rates (~0.01 mm h−1, leveling off at low flow rates. There is significant variability in the recession timescale at a given flow rate between basins, which correlates with climate and geomorphic variables such as the ratio of mean streamflow to precipitation and soil water infiltration capacity. Stepwise multiple regression was used to construct a six-variable predictive model that explained some 80 % of the variance in recession timescale at high flow rates and 30–50 % at low flow rates. Seasonal and interannual variability in inferred storage shows similar time evolution to regional-scale water storage variability estimated from GRACE satellite gravity data and from land surface modeling forced by observed meteorology, but is up to a factor of 10 smaller. Study of this discrepancy in the inferred storage amplitude may provide clues to the range of validity of the recession curve approach to relating runoff and storage.

  12. Financialisation, oil and the Great Recession

    2015-01-01

    This article addresses the role of world oil price hike of 2007–08 in serving to transform the financial and banking crisis into what is commonly referred to the Great Recession. Existing literature on the global crisis of 2007–09 tends to view it as a financial or banking phenomenon, with analyses focusing mainly on state policies, governance mechanisms and market dynamics in transforming the banking crisis of 2007–08 into the economic recession of 2008-12/13 Although often attributing the global meltdown to wider phenomenon of financialisation, rarely do existing perspectives delve into the role of the commodity sector in the global credit crunch. In this paper, we aim to fill this gap, by inquiring into the role played by oil as a financial asset class in the political economy of the global crisis. - Highlights: • We study the oil price and its effects on the Great Recession. • We approach oil as a financial asset class. • We observe the transformation of oil through deregulation.

    We studied the genetic background of a family with SCA, showing dominant inheritance and anticipation. Muscle histology, POLG1 gene sequence, neuropathology and mitochondrial DNA analyses in a mother and a son showed typical findings for a mitochondrial disorder, and both were shown to be homozygous for a recessive POLG1 mutation, underlying mitochondrial recessive ataxia syndrome, MIRAS. The healthy father was a heterozygous carrier for the same mutation. Recessively inherited MIRAS mutations should be tested in dominantly inherited SCAs cases of unknown cause, as the high carrier frequency of MIRAS may result in two independent introductions of the mutant allele in the family and thereby mimic dominant inheritance.

    Full Text Available Gingival recession represents a serious problem, for both patient and physician, especially when exposure of the radicular surface is related to the deterioration of the aesthetic aspect and to a more pronounced dental hyper‐ sensitivity. Scope of the study: to determine the preva‐ lence and severity of recessions in young adults, correlated with the local dental, as well as socio‐economic and cultu‐ ral conditions. Materials and method: A number of 85 persons, having addressed the Department of Perio‐ dontology, Faculty of Dental Medicine of Iasi, between February‐May 2011, were examined. The following para‐ meters were recorded: sex, education level, total number of gingival recessions at the level of the oral cavity, type of brush employed, frequency of dental brushing, amount of attached gingiva, existence of labial phrenum, type of occlusion, presence of certain complications induced by the manifestation of recessions, such as hypersensitivity. Results and discussion: Analysis and correlation of data showed that the most important role in the occurrence of recessions was played by the local factors, which intensi‐ fied the action of the determining element, the bacterial plaque. Thus, the nature of periodontal recessions is of inflammatory type, those with traumatic causes being sta‐ tistically non‐significant. The type of periodontium influ‐ enced the development of recessions, so that, for a delicate periodontium, 10.4 recessions/patient have been discove‐ red, while, in a thick periodontium, only 7 recessions/ patient. In cases of phrenectomies with insertion in the vicinity of the gingival margin, recessions of various sizes have been always present. In cases of dental occlusion, the obtained data suggest that the occurrence of recessions is not considerably influenced by the type of occlusion, the values being quite close. As to their sizes, most of the reces‐ sions were situated at a level of 2‐3 mm, a

    Full Text Available Differences in recess physical activity (PA according to perceived school environment among elementary school children were examined. Participants were 103 children from two schools in Japan. PA was measured using accelerometry for seven consecutive days. Time spent in sedentary or PA (light, moderate, or vigorous during their morning recess (25 min and lunch recess (15 min was determined. The School Physical Activity Environment Scale (three factors: equipment, facility, and safety was used to investigate perceived school environment. Environmental factor scores were assigned to low or high groups for each factor by median. An analysis of covariance, with grade as the covariate, was conducted separately by gender to examine differences in PA between two groups. During lunch recess, boys in the high-equipment group spent significantly more time in moderate PA (high: 1.5; low: 0.8 min whereas girls in this group spent less time in light PA (9.3, 11.0. Boys in the high-facility group spent significantly less time in sedentary (2.3, 3.9 and more time in vigorous PA (2.4, 1.4 during lunch recess, and girls spent more time in moderate (2.1, 1.2 and vigorous PA (1.9, 1.3 during morning recess. Differences were observed in recess PA according to school environment perceptions. The present study may be useful for further intervention studies for the promotion of PA during recess.

    Full Text Available Hybrid vigor contributes in a large way to the yield and quality of cotton (Gossypium hirsutum fiber. Although microRNAs play essential regulatory roles in flower induction and development, it is still unclear if microRNAs are involved in male sterility, as the regulatory molecular mechanisms of male sterility in cotton need to be better defined. In this study, two independent small RNA libraries were constructed and sequenced from the young buds collected from the sporogenous cell formation to the meiosis stage of the male sterile line Yu98-8A and the near-isogenic line. Sequencing revealed 1588 and 1536 known microRNAs and 347 and 351 novel miRNAs from male sterile and male fertile libraries, respectively. MicroRNA expression profiles revealed that 49 conserved and 51 novel miRNAs were differentially expressed. Bioinformatic and degradome analysis indicated the regulatory complexity of microRNAs during flower induction and development. Further RT-qPCR and physiological analysis indicated that, among the different Kyoto Encyclopedia Gene and Genomes pathways, indole-3-acetic acid and gibberellic acid signaling transduction pathways may play pivotal regulatory functions in male sterility.

  20. A collection of evidence for the impact of the economic recession on road fatalities in Great Britain.

    2015-07-01

    There was a considerable reduction in the number of fatalities on British roads between 2007 and 2010. This substantial change led to debate as to the cause of the reduction. Multiple sources of information and evidence have been collated including STATS19 road accident data, population data, socio-demographic data, economic patterns, weather trends and traffic and vehicle data. Summary analyses of these data sources show a reduction in overall traffic, a large reduction in HGV traffic, a reduction in young male drivers, a reduction in speeding, and a reduction in drink driving during the recession period. All of these reductions can be associated with a reduction in fatal accidents and have led to the conclusion that the economic recession changed behaviours in such a way that fewer people were killed on the roads in Britain during this period.

    Full Text Available This study analyzes the impact of the outbreak of the Great Recession of 2007 on the behavior of the Indian stock market. The SENSEX index of the Bombay Stock Exchange is analyzed for the prerecession period of January 2002 – November 2007 and the postrecession outbreak period of December 2007 – July 2010. Substantial increase in SENSEX return volatility observed during the post-recession outbreak period, whereas no substantial difference in returns between two periods is found. Also strong co-movements in returns and volatility are observed between the SENSEX and other major stock indexes during the post-recession period. Our results establish the dominance of global factors in influencing Indian stock market behavior during periods of economic turmoil.

    2018-07-01

    This study investigates how the ecologically unequal exchange of carbon dioxide emissions varies with economic recessions. I propose a country-specific approach to examine (1) the relationship between carbon dioxide emissions in developing countries and the "vertical flow" of exports to the United States; and (2) the variations of the relationship before, during, and after two recent economic recessions in 2001 and 2008. Using data on 69 developing nations between 2000 and 2010, I estimate time-series cross-sectional regression models with two-way fixed effects. Results suggest that the vertical flow of exports to the United States is positively associated with carbon dioxide emissions in developing countries. The magnitude of this relationship increased in 2001, 2009, and 2010, and decreased in 2008, but remained stable in non-recession periods, suggesting that economic recessions in the United States are associated with variations of ecologically unequal exchange. Results highlight the impacts of U.S. recessions on carbon emissions in developing countries through the structure of international trade. Copyright © 2018 Elsevier Inc. All rights reserved.

    2016-03-01

    This is the first study to examine broadly the overall net change in U.S. population estimates of alcohol use related to a recession--The Great Recession--among individuals who remain employed. The alcohol variables included drinker status, usual frequency and quantity of alcohol use, frequency of heavy drinking and intoxication, as well as contextual assessments of the frequency and quantity of alcohol use during the workday and after work. The moderating influence of gender, race, and age also was explored. Data for this repeated cross-sectional study were obtained from 2 national telephone surveys of U.S. workers. The first survey occurred prior to the Great Recession (2002-2003; N = 2,501), whereas the second survey occurred during and after the official end of the Great Recession (2008-2011; N = 2,581). The results revealed that the recession was related to a higher proportion of drinkers among middle-aged employees, but not among young employees. Gender and race did not moderate the relation of the recession to drinker status. Among drinkers, the recession was not related to usual alcohol use (frequency and quantity), but was positively related to the frequency of heavy drinking and intoxication. Further, the recession had a differential relation to the contextual alcohol measures. It was negatively related to the frequency and quantity of workday alcohol use, but was positively related to the frequency and quantity of afterwork alcohol use. Among drinkers, gender, race, and age did not moderate the relation of the recession to alcohol use. (c) 2016 APA, all rights reserved).

    Many patients undergo orthodontic treatment for aesthetic improvement. It is well established that the patients who undergo orthodontic treatment have a high susceptibility to present plaque accumulation on their teeth because of the presence of brackets, wires and/or other orthodontic elements on the teeth surfaces with which the oral hygiene procedures might be more difficult. The orthodontic treatment is a double-action procedure regarding the periodontal tissues which may be very meaningful in increasing the periodontal health status and may be a harmful procedure which can be followed by several types of periodontal complications. There is a strong correlation between the severity and extent of gingival recessions and the orthodontic treatment suggesting that orthodontic tooth movement may lead to gingival recession. The principal objective in the treatment of gingival recession is to cover the exposed root surfaces to improve aesthetics and to reduce hypersensitivity. Different soft tissue grafting procedures have been proposed in the treatment of gingival recessions. Subepithelial connective tissue graft is a reliable method for treatment of gingival recession. The purpose of this case report was to illustrate the relationship between orthodontic therapy and gingival recession and to describe the management of this case.

    A period of economic recession may be particularly difficult for people with mental health problems as they may be at higher risk of losing their jobs, and more competitive labour markets can also make it more difficult to find a new job. This study assesses unemployment rates among individuals with mental health problems before and during the current economic recession. Using individual and aggregate level data collected from 27 EU countries in the Eurobarometer surveys of 2006 and 2010, we examined changes in unemployment rates over this period among individuals with and without mental health problems. Following the onset of the recession, the gap in unemployment rates between individuals with and without mental health problems significantly widened (odds ratio: 1.12, 95% confidence interval: 1.03, 1.34). This disparity became even greater for males, and individuals with low levels of education. Individuals with mental health problems living in countries with higher levels of stigmatizing attitudes regarding dangerousness of people with mental illness were more vulnerable to unemployment in 2010, but not 2006. Greater agreement that people with mental health problems have themselves to blame, was associated with lower likelihood of unemployment for individuals with and without mental health problems. These findings study suggest that times of economic hardship may intensify social exclusion of people with mental health problems, especially males and individuals with lower education. Interventions to combat economic exclusion and to promote social participation of individuals with mental health problems are even more important during times of economic crisis, and these efforts should target support to the most vulnerable groups.

    Full Text Available Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS is a neurodegenerative disorder characterized by late infantile onset spastic ataxia and other neurological features. Initially described in the Charlevoix-Saguenay region of Quebec, Canada, it is being increasingly reported from many other countries. Here, we present the case of a 20-year-old male from South India, who presented with progressive ataxia, spasticity, and peripheral neuropathy with imaging features and genetic testing suggestive of SACS gene-related ARSACS. The phenotypic variability from other cases and occurrence in a geographically distinct region is stressed upon to alert the clinicians to consider ARSACS in progressive ataxias.

    Economic recessions are associated with increases in suicide rates but there is little information for non-fatal self-harm. To investigate the impact of the recent recession on rates of self-harm in England and problems faced by patients who self-harm. Analysis of data from the Multicentre Study of Self-harm in England for 2001-2010 and local employment statistics for Oxford, Manchester and Derby, including interrupted time series analyses to estimate the effect of the recession on rates of self-harm. Rates of self-harm increased in both genders in Derby and in males in Manchester in 2008-2010, but not in either gender in Oxford, results which largely followed changes in general population unemployment. More patients who self-harm were unemployed in 2008-10 compared to before the recession. The proportion in receipt of sickness or disability allowances decreased. More patients of both genders had employment and financial problems in 2008-2010 and more females also had housing problems, changes which were also largely found in employed patients. We have assumed that the recession began in 2008 and information on problems was only available for patients having a psychosocial assessment. Increased rates of self-harm were found in areas where there were greater rises in rates of unemployment. Work, financial and housing problems increased in people who self-harmed. Changes in welfare benefits may have contributed. None. Copyright © 2015 Elsevier B.V. All rights reserved.

  18. Economic recession and fertility in the developed world.

    2011-01-01

    This article reviews research on the effects of economic recessions on fertility in the developed world. We study how economic downturns, as measured by various indicators, especially by declining GDP levels, falling consumer confidence, and rising unemployment, were found to affect fertility. We also discuss particular mechanisms through which the recession may have influenced fertility behavior, including the effects of economic uncertainty, falling income, changes in the housing market, and rising enrollment in higher education, and also factors that influence fertility indirectly such as declining marriage rates. Most studies find that fertility tends to be pro-cyclical and often rises and declines with the ups and downs of the business cycle. Usually, these aggregate effects are relatively small (typically, a few percentage points) and of short durations; in addition they often influence especially the timing of childbearing and in most cases do not leave an imprint on cohort fertility levels. Therefore, major long-term fertility shifts often continue seemingly uninterrupted during the recession—including the fertility declines before and during the Great Depression of the 1930s and before and during the oil shock crises of the 1970s. Changes in the opportunity costs of childbearing and fertility behavior during economic downturn vary by sex, age, social status, and number of children; childless young adults are usually most affected. Furthermore, various policies and institutions may modify or even reverse the relationship between recessions and fertility. The first evidence pertaining to the recent recession falls in line with these findings. In most countries, the recession has brought a decline in the number of births and fertility rates, often marking a sharp halt to the previous decade of rising fertility rates.

    We study the dynamics of a spherical rigid body that rocks and rolls on a plane under the effect of gravity. The distribution of mass is non-uniform and the centre of mass does not coincide with the geometric centre. The symmetric case, with moments of inertia I 1 = I 2 3 , is integrable and the motion is completely regular. Three known conservation laws are the total energy E, Jellett's quantity Q J and Routh's quantity Q R . When the inertial symmetry I 1 = I 2 is broken, even slightly, the character of the solutions is profoundly changed and new types of motion become possible. We derive the equations governing the general motion and present analytical and numerical evidence of the recession, or reversal of precession, that has been observed in physical experiments. We present an analysis of recession in terms of critical lines dividing the (Q R , Q J ) plane into four dynamically disjoint zones. We prove that recession implies the lack of conservation of Jellett's and Routh's quantities, by identifying individual reversals as crossings of the orbit (Q R (t), Q J (t)) through the critical lines. Consequently, a method is found to produce a large number of initial conditions so that the system will exhibit recession.

    To examine the association between the Great Recession of 2007-2009 and health care expenditures along the health care spending distribution, with a focus on racial/ethnic disparities. Secondary data analyses of the Medical Expenditure Panel Survey (2005-2006 and 2008-2009). Quantile multivariate regressions are employed to measure the different associations between the economic recession of 2007-2009 and health care spending. Race/ethnicity and interaction terms between race/ethnicity and a recession indicator are controlled to examine whether minorities encountered disproportionately lower health spending during the economic recession. The Great Recession was significantly associated with reductions in health care expenditures at the 10th-50th percentiles of the distribution, but not at the 75th-90th percentiles. Racial and ethnic disparities were more substantial at the lower end of the health expenditure distribution; however, on average the reduction in expenditures was similar for all race/ethnic groups. The Great Recession was also positively associated with spending on emergency department visits. This study shows that the relationship between the Great Recession and health care spending varied along the health expenditure distribution. More variability was observed in the lower end of the health spending distribution compared to the higher end. © Health Research and Educational Trust.

    Full Text Available The main problems about research and application of two-line hybrid rice were reviewed, including the confusing nomenclature and male sterile lines classification, the unclear characteristics of photoperiod and temperature responses and the unsuitable site selection for male sterile line and hybrid rice seed production. In order to efficiently and accurately use dual-purpose genic male sterile lines, four types, including PTGMS (photo-thermo-sensitive genic male sterile rice, TGMS (thermo-sensitive genic male sterile rice, reverse PTGMS and reverse TGMS, were proposed. A new idea for explaining the mechanism of sterility in dual-purpose hybrid rice was proposed. The transition from sterile to fertile was involved in the cooperative regulation of major-effect sterile genes and photoperiod and/or temperature sensitive ones. The minor-effect genes with accumulative effect on sterility were important factors that affected the critical temperature of sterility transfer. In order to make better use of dual-purpose lines, the characterization of responses to photoperiod and temperature of PTGMS should be made and the identification method for the characterization of photoperiod and temperature responses of PTGMS should also be put forward. The optimal ecological site for seed production could be determined according to the historical climate data and the requirements for the meteorological conditions during the different periods of seed production.

    1987-10-01

    Light and electron microscopy of the hypothalamic ventricle in neonatal rats demonstrate morphological specializations of the ventricular wall at the level of the premammillary region of the third ventricle. The morphological features are: (1) A ventricular recess that we have called the "hypothalamic dorso-lateral recess" (HDR). (2) The presence of intraventricular capillaries near the dorso-lateral recess. (3) The HDR possessing a specialized ependymal lining; this consists of non-ciliated cells with short microvilli and bleb-like processes. (4) The existence of cerebrospinal fluid-contacting neurons within the HDR. (5) The presence of numerous phagocytic supraependymal cells. The HDR is not found in adult rats. This indicates that the dorso-lateral recess may play a physiological role during development.

  10. Recessive Resistance to Plant Viruses: Potential Resistance Genes Beyond Translation Initiation Factors

    Directory of Open Access Journals (Sweden)

    Masayoshi Hashimoto

    2016-10-01

    Full Text Available The ability of plant viruses to propagate their genomes in host cells depends on many host factors. In the absence of an agrochemical that specifically targets plant viral infection cycles, one of the most effective methods for controlling viral diseases in plants is taking advantage of the host plant’s resistance machinery. Recessive resistance is conferred by a recessive gene mutation that encodes a host factor critical for viral infection. It is a branch of the resistance machinery and, as an inherited characteristic, is very durable. Moreover, recessive resistance may be acquired by a deficiency in a negative regulator of plant defense responses, possibly due to the autoactivation of defense signaling. Eukaryotic translation initiation factor (eIF 4E and eIF4G and their isoforms are the most widely exploited recessive resistance genes in several crop species, and they are effective against a subset of viral species. However, the establishment of efficient, recessive resistance-type antiviral control strategies against a wider range of plant viral diseases requires genetic resources other than eIF4Es. In this review, we focus on recent advances related to antiviral recessive resistance genes evaluated in model plants and several crop species. We also address the roles of next-generation sequencing and genome editing technologies in improving plant genetic resources for recessive resistance-based antiviral breeding in various crop species.

  11. Overburndened and Underfunded: California Public Schools Amidst the Great Recession

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Since 2008, many nations, including the United States, have struggled with the effects of a global recession. The state of California has been particularly impacted by the Great Recession. Unemployment rates in California are among the highest in the United States, and a weak fiscal environment has forced deep cutbacks to a variety of state services. This study uses California as a case to explore the effects of economic crisis on public schools and the students they serve. The study draws on two years of survey and interview data with a representative sample of public school principals across California. The data show that, during the Great Recession, students have experienced growing social welfare needs that often shape their well-being and their performance in schools. We also find that the capacity of public schools to meet these needs and provide quality education has been eroded by budget cuts. This study finds that schools primarily serving low-income families have been hardest hit during the recession, in part because they cannot raise private dollars to fill the gap left by public sector cuts. The Great Recession thus has undermined educational quality while producing widening educational inequality in California.

  12. Male songbirds provide indirect parental care by guarding females during incubation

    Across many taxa, guarding of fertile mates is a widespread tactic that enhances paternity assurance. However, guarding of mates can also occur during the nonfertile period, and the fitness benefits of this behavior are unclear. Male songbirds, for example, sometimes guard nonfertile females during foraging recesses from incubation. We hypothesized that guarding postreproductive mates may have important, but unrecognized, benefits by enhancing female foraging efficiency, thereby increasing time spent incubating eggs. We tested the hypothesis in 2 songbird species by examining female behavior during natural and experimentally induced absences of males. Male absence caused increased vigilance in foraging females that decreased their efficiency and resulted in less time spent incubating eggs. Male guarding of nonfertile females can thus provide a previously unrecognized form of indirect parental care.

    Objective: To evaluate the CT features and implications of the pericardial sinuses and recesses effusion by combining the sectional cadavers and 16 multi-slice CT (MSCT) reformation. Methods: The anatomy and communication of the pericardial sinuses and recesses on the axial, coronal and saggital sectional cadavers (respectively 1 case), and the morphologic features on MSCT reformatted images in 104 patients were observed. The detection rate of effusion was analyzed. Results: The sectional cadavers and CT images showed that the pericardial sinuses and recesses were formed by the reflections of the pericardium on the root of the great vessels. The detection rate of the sinuses and recesses was lower in small effusion than in moderate and large effusion (P<0.05). The superior aortic recess was the most common recess for pericardial effusion. Conclusion: The MSCT reformatted images can show the morphologic features of pericardial sinuses and recesses effusion and communications with the pericardial cavity, help differentiate pericardial effusion from other mediastinal or pericardial lesions.

    Operative findings of the supratubal recess were examined in the 30 patients with acquired cholesteatoma. They were compared with findings of high-resolution CTs (HRCTs) obtained preoperatively. Thus the role of HRCT in cholesteatoma involving the supratubal recess were evaluated. HRCTs of 172 ears without otitis media and 65 ears with tubotympanic type otitis media were analyzed as control. The HRCT has proved to provide excellent informations regarding the presence of cholesteatoma in the supratubal recess. Diagnostic points were as follows. (1) Destruction of the ''cog''. (2) Erosion or destruction of surrounding bony structures, for example, facial canal, tympanic tegmen. (3) Soft tissue density in the supratubal recess. (author)

    The RCR-analysis of 81 γ- and neutron-induced vg recessive mutations in ripe sperm of Drosophila melanogaster males of combined with complementation assay with the vg[nw83b27] deletion mutation is used to detect precisely the RGE values of neutrons (0.85 MeV) under the chromosome and point mutation induction. The results obtained show that all genetic end-points increase linearly with γ-ray and neutron dose. Thereby, the efficacy of neutrons is found to be twice (and more) as large as that of γ-rays under the all macro- and micro-aberration mutation induction. Unlike that, the RGE of neutrons are more than twice as low as that of γ-rays under the gene/point mutation induction [ru

    Full Text Available This paper analyses the patterns of engagement in education of young people of immigrant origin resident in Spain, using data from the Spanish Labour Force Survey. The results show that the probability that immigrant-origin youth may be outside the educational system is higher than the probability for native youth, but only for those who came to Spain after the age of ten years old. In addition, their reaction to changes in the employment situation has been less intense. Also, parental educational resources slow down the reaction to changes in employment opportunities for the children of native people and daughters of immigrants, decreasing the inequality within each group in contexts of recession, but this is not the case for male young immigrants.

    Full Text Available A period of economic recession may be particularly difficult for people with mental health problems as they may be at higher risk of losing their jobs, and more competitive labour markets can also make it more difficult to find a new job. This study assesses unemployment rates among individuals with mental health problems before and during the current economic recession.Using individual and aggregate level data collected from 27 EU countries in the Eurobarometer surveys of 2006 and 2010, we examined changes in unemployment rates over this period among individuals with and without mental health problems.Following the onset of the recession, the gap in unemployment rates between individuals with and without mental health problems significantly widened (odds ratio: 1.12, 95% confidence interval: 1.03, 1.34. This disparity became even greater for males, and individuals with low levels of education. Individuals with mental health problems living in countries with higher levels of stigmatizing attitudes regarding dangerousness of people with mental illness were more vulnerable to unemployment in 2010, but not 2006. Greater agreement that people with mental health problems have themselves to blame, was associated with lower likelihood of unemployment for individuals with and without mental health problems.These findings study suggest that times of economic hardship may intensify social exclusion of people with mental health problems, especially males and individuals with lower education. Interventions to combat economic exclusion and to promote social participation of individuals with mental health problems are even more important during times of economic crisis, and these efforts should target support to the most vulnerable groups.

    This paper examines the association between the Great Recession and four measures of the risk for maternal child abuse and neglect: (1) maternal physical aggression; (2) maternal psychological aggression; (3) physical neglect by mothers; and (4) supervisory/exposure neglect by mothers. It draws on rich longitudinal data from the Fragile Families and Child Wellbeing Study, a longitudinal birth cohort study of families in 20 U.S. cities (N = 3,177; 50% African American, 25% Hispanic; 22% non-Hispanic white; 3% other). The study collected information for the 9-year follow-up survey before, during, and after the Great Recession (2007-2010). Interview dates were linked to two macroeconomic measures of the Great Recession: the national Consumer Sentiment Index and the local unemployment rate. Also included are a wide range of socio-demographic controls, as well as city fixed effects and controls for prior parenting. Results indicate that the Great Recession was associated with increased risk of child abuse but decreased risk of child neglect. Households with social fathers present may have been particularly adversely affected. Results also indicate that economic uncertainty during the Great Recession, as measured by the Consumer Sentiment Index and the unemployment rate, had direct effects on the risk of abuse or neglect, which were not mediated by individual-level measures of economic hardship or poor mental health.

    Recess is a part of the elementary school day with strong implications for school climate. Positive school climate has been linked to a host of favorable student outcomes, from attendance to achievement. We examine 6 low-income elementary schools' experiences implementing a recess-based program designed to provide safe, healthy, and inclusive play to study how improving recess functioning can affect school climate. Data from teacher, principal, and recess coach interviews; student focus groups; recess observations; and a teacher survey are triangulated to understand the ways that recess changed during implementation. Comparing schools that achieved higher- and lower-functioning recesses, we link recess functioning with school climate. Recess improved in all schools, but 4 of the 6 achieved a higher-functioning recess. In these schools, teachers and principals agreed that by the end of the year, recess offered opportunities for student engagement, conflict resolution, pro-social skill development, and emotional and physical safety. Respondents in these four schools linked these changes to improved overall school climate. Recess is an important part of the school day for contributing to school climate. Creating a positive recess climate helps students to be engaged in meaningful play and return to class ready to learn. © 2014, American School Health Association.

    2018-03-01

    This study examined whether economic changes related to the 2008-2009 Recession were associated with employment status and job quality indicators among older workers in Europe and Israel. Data were derived from 4917 respondents (16,090 observations both before and after the recession) from 13 countries who participated in the Survey of Health, Ageing and Retirement in Europe. Annual data on gross domestic product (GDP) per capita, life expectancy, and quarterly unemployment rates were assigned to employment assessments from 2004 to 2013. Using difference-in-differences models, we assessed the recession's implications on individual employment outcomes, while isolating cyclical variation within countries and individual changes over time. Among older workers, decreases in GDP were associated with an increase in the likelihood of being unemployed and a decrease in the likelihood of being retired. An increasing country-level unemployment rate had a significant effect on aspects of job quality: lower prospects for job advancement, lower job security, and higher job satisfaction. Economic recessions are thus negatively associated with employment outcomes for older workers. However, malleable policy-related factors such as longer tenure and improved general health can limit the negative employment and job quality outcomes following a recession.

    While sparse literature exists investigating the impact of the Great Recession on various sectors of the economy, there is virtually no research that studies the effect of the Great Recession, or past recessions, on schools. This paper starts to fill the void. Studying school funding during the recession is of paramount importance because schools…

    Full Text Available In light of the recent macroeconomic instability in global markets, we examine the evolution of competitive dynamics and firm profitability when industries are subject to recessions. Although ordinary intuition leads most to view recessions as harmful, we highlight conditions under which they enhance the relative value of industry-level supply-side isolating mechanisms, thereby affording early movers significant and sustainable profit advantages vis-à-vis laggards. We observe that the distribution of firm size within the industry switches from a bi-modal distribution (i.e., one dominated by both small and large firms to a right-skewed one (i.e., dominated mostly by large firms in these contexts, thereby signaling the rise of important opportunities in the form of less rivalrous competitive contexts for survivors of recessions. We derive our results from formal modeling and multiple simulation runs.

    Full Text Available Recession is an extremely difficult period for most companies. Especially when a recession has universal dimensions, many companies find themselves unprepared to face great challenges. While marketing in good times has a long-term focus, a broad scope, it is benefits- and opportunities-driven and proactive, in bad times it has a short-term focus, limited and narrow scope, it is cost-and sales-driven and reactive. Panic is not the right reaction. Such difficult times should be overcome through methodical and well planned actions. After all, research has shown that those companies that take a proactive stance and treat the recession as an opportunity are likely to come out of the crisis stronger than before. Specific marketing activities have been proved to be beneficial to companies during a downturn. Below we analyze, ten marketing survival strategies and tactics.

    Full Text Available Black gram [V. mungo (L. Hepper] is an important legume crop extensively grown in south and south-east Asia, where it is a major source of dietary protein for its predominantly vegetarian population. However, lack of genomic information and markers has become a limitation for genetic improvement of this crop. Here, we report the transcriptome sequencing of the immature seeds of black gram cv. TU94-2, by Illumina paired end sequencing technology to generate transcriptome sequences for gene discovery and genic-SSR marker development. A total of 17.2 million paired-end reads were generated and 48,291 transcript contigs (TCS were assembled with an average length of 443 bp. Based on sequence similarity search, 33,766 TCS showed significant similarity to known proteins. Among these, only 29,564 TCS were annotated with gene ontology (GO functional categories. A total number of 138 unique KEGG (Kyoto Encyclopedia of Genes and Genomes pathways were identified, of which majority of TCS are grouped into purine metabolism (678 followed by pyrimidine metabolism (263. A total of 48,291 TCS were searched for SSRs and 1,840 SSRs were identified in 1,572 TCS with an average frequency of one SSR per 11.9 kb. The tri-nucleotide repeats were most abundant (35% followed by di-nucleotide repeats (32%. PCR primer pairs were successfully designed for 933 SSR loci. Sequences analyses indicate that about 64.4% and 35.6% of the SSR motifs were present in the coding sequences (CDS and untranslated regions (UTRs respectively. Tri-nucleotide repeats (57.3% were preferentially present in the CDS. The rate of successful amplification and polymorphism were investigated using selected primers among 18 black gram accessions. Genic-SSR markers developed from the Illumina paired end sequencing of black gram immature seed transcriptome will provide a valuable resource for genetic diversity, evolution, linkage mapping, comparative genomics and marker-assisted selection in black gram.

    Full Text Available This paper is an attempt to translate economic figures and indices into the living conditions of people who are behind the statistics of the U.S. economic recession, which officially began in December 2007 and ended in June 2009. The pathology of the Great Recession began with the financial shock, which resulted from the buildup of financial mischief since the 1980s, and the burst of its real estate bubble by 2007. A recession is a man-made tragedy with a large human cost. This paper addresses this flip side of the current economic crisis by examining its human consequences on different social classes and groups. A breakdown of various data proves that the working class, the majority in U.S. society, suffers most from the recession, and yet, some amongst them even more than others, depending upon their social status with regard to education, race, and age.

    Abstract: This paper examines whether unemployment of non-western immigrant workers in the Netherlands was disproportionally affected by the Great Recession. We analyze unemployment data covering the period November 2007 to February 2013 finding that the Great Recession affected unemployment rates of non-western immigrant workers in absolute terms more than unemployment rates of native workers. However, in relative terms there is not much of a difference. We also find that the sensitivity of ...

    Full Text Available The objective of the article was to present possible applications of recession flow curve in a small lowland watershed retention discharge size evaluation. The examined woodland micro catchment area of 0.52 sq km is located in Puszcza Zielonka in central Wielkopolska. The Hutka catchment is typically woody with high retention abilities. The catchment of the Hutka watercourse is forested in 89%, the other 11% is covered by swamps and wasteland. The predominant sites are fresh mixed coniferous forest (BMśw, fresh coniferous forest (Bśw and alder carr forest (Ol. Landscape in catchment is characterized by a large number of interior depressions, filled partly with rainwater or peatbogs, with poorly developed natural drainage. The watercourses do not exceed 1 km in length, the mean width is approx. 0.5 m, while mean depth ranges from 0.2 to 0.3 m. During hydrological research conducted in 1997/1998–1999/2000, 35 major (characteristic raised water stages were observed in Hutka after substantial precipitation. The recession curve dating from 18–24 September 2000 has the α and n rates nearest to average. Comparing the model curve and the curve created by observing watercourse flow, one can notice their resemblance and that they have similar ordinate values as well as shape. In the case of other recession curves, the maximum differences of ordinate values are also about 0.1–0.2 l/s/km2. The measuured α and n rates do not reveal any regularities. There are no significant statistical Horton model parameter (for recession flow curves dependencies between α and n and e.g. initial flows (Qo or the whole period of high water waves (Qp. Consequently, calculated relation between these parameters is only an approximation for the general evaluation of the retention discharge in the catchment area towards retention with flow function.

  16. Do high levels of unemployment influence the health of those who are not unemployed? A gendered comparison of young men and women during boom and recession.

    Research has shown that health among young people, particularly women, deteriorates during a recession compared to a boom. It seems that the trade cycle mainly affects the health of those who are not long-term unemployed. The aim of this study was to analyse the relation between the health of non-unemployed people and the levels of unemployment in society. Two groups of young people aged 21 were surveyed, one in 1986 (the boom group, n = 1083) and one in 1994 (the recession group, n = 898). The non-response rate was 2% in the first and 10% in the second group. Both groups were investigated with a self-administered questionnaire, which included questions about somatic and psychological health, as well as experiences of employment, unemployment, education and labour market programmes. Young men and women generally reported more somatic and psychological symptoms during recession than boom. The only exception was psychological symptoms among men, which was of the same magnitude during both periods. Poorer health during recession was found among women in work and in labour market programmes, as well as among both male and female students. Multiple regression analysis was performed in order to analyse if the occupational-related health effects of the trade cycle remained after controlling for possible moderating factors. The effects of unemployment in society on young people's health may be mediated through pessimism about the future, high demands and financial problems. Lack of control over the work situation may also be an important contributing factor to ill health among women during recession. The trade cycle was correlated with ill health among women only. Possible explanations for poorer health among women during a recession were discussed.

    Traditionally, economic recessions have resulted in decreased utilization of preventive health services. To explore racial and ethnic differences in breast and cervical cancer screening rates before and during the Great Recession. The Medical Expenditure Panel was the source for identifying 10,894 women, ages 50-74 for breast screening and 19,957 women, ages 21-65 for cervical screening. Survey years included 2004-2005 and 2009-2010. Dependent variables were as follows: 1) receipt of mammogram within the past 2 years; and 2) receipt of a Pap smear within the past 3 years. The interaction of the recession and the likelihood of screening between whites and minorities was analyzed. Multivariate regressions were applied to estimate the likelihood of screening for the two time periods while controlling for a recession variable. Nationally, breast and cervical cancer screening rates dropped during the recession period; white women contributed most to the decline. However, there were significant improvements in timely screening for both cancers among Hispanics during the recession period. After controlling for the recession, African American women were more likely to have timely screenings compared to white women. Screening rates during the recession were lowest in the South, Midwest and West. There was a national reduction in the percentages of women who obtained timely breast and cervical screenings during the Great Recession. Outreach efforts are needed to ensure that women who were not screened during the recession are screened. Widespread education about the Affordable Care Act may be helpful.

  20. Financial Strain and Mental Health Among Older Adults During the Great Recession.

    2016-07-01

    The economic recession has garnered the interest of many scholars, with much attention being drawn to how the recession has affected labor force participation, household wealth, and even retirement decisions. Certainly, the Great Recession has influenced the financial well-being of older adults, but has it had discernible effects on mental health? This study draws on 5,366 respondents from the Health and Retirement Study (2006-2010) to examine objective and subjective measures of financial well-being in the period surrounding the Great Recession. Guided by cumulative inequality theory, this research investigates whether the economic downturn contributed to worsening anxiety and depressive symptoms over a 4-year period. Results from linear fixed effects models reveal that decreases in objective financial resources were associated with increased financial strain during the Great Recession. Unlike the objective indicators, however, financial strain was a strong and robust predictor of worsening mental health between 2006 and 2010. Building on prior research, this study elucidates the factors that shape financial strain and provides evidence that the Great Recession not only affected the financial well-being of older adults but also had adverse effects on mental health. © The Author 2016.

    Full Text Available Autosomal recessive polycystic kidney disease (ARPKD is one of the most common inheritable disease manifesting in infancy and childhood with a frequency of 1:6,000 to 1:55,000 births. The patient in her second trimester presented with a history of amenorrhea. Ultrasound examination revealed bilateral, enlarged, hyperechogenic kidneys, placentomegaly, and severe oligohydramnios. The pregnancy was terminated. An autopsy was performed on the fetus. Both the kidneys were found to be enlarged and the cut surface showed numerous cysts. The liver sections showed changes due to fibrosis. The final diagnosis of autosomal recessive polycystic kidney disease was made based on these findings. In this article, we correlate the ante-natal ultrasound and histopathological findings in autosomal recessive polycystic kidney disease.

    This study draws on the Fragile Families and Child Wellbeing Study (N=2,032), a birth cohort study of families with children from 20 U.S. cities. Interviews occurred between August 2007, and February 2010, when the children were approximately 9 years old. Macro-economic indicators of the Great Recession such as the Consumer Sentiment Index and unemployment and home foreclosure rates were matched to the data to estimate the links between different measures of the Great Recession and high frequency maternal spanking. We find that the large decline in consumer confidence during the Great Recession, as measured by the Consumer Sentiment Index, was associated with worse parenting behavior. In particular, lower levels of consumer confidence were associated with increased levels of high frequency spanking, a parenting behavior that is associated with greater likelihood of being contacted by child protective services.

    This study explored the relationship between children's basic psychological needs satisfaction at recess, level of recess physical activity motivation (RPAM), and recess physical activity (RPA). Fifth-grade children (N = 203; 50.2% boys; 71.7% healthy-weight) completed measures of age, gender, basic psychological need satisfaction, and level of self-determined motivation for RPA. Children also wore pedometers during six consecutive 30-min mid-school-day recesses. Multiple regression analyses indicated unique significant predictors of RPAM and RPA according to gender and weight status. RPAM was significantly predicted by all three basic psychological needs for boys and only competence need satisfaction for girls and healthy-weight children. RPA was predicted by RPAM for girls, competence need satisfaction for overweight children, and autonomy need satisfaction for boys and healthy-weight children. Findings support self-determination theory and provide important insight into the variations in psychological predictors of motivation for RPA and actual physical activity behavior based on gender and weight status.

    Economic stressors have been retrospectively associated with net population increases in nonspecific psychological distress (PD). However, no sentinels exist to evaluate contemporaneous associations. Aggregate Internet search query surveillance was used to monitor population changes in PD around the United States' Great Recession. Monthly PD query trends were compared with unemployment, underemployment, homes in delinquency and foreclosure, median home value or sale prices, and S&P 500 trends for 2004-2010. Time series analyses, where economic indicators predicted PD one to seven months into the future, were performed in 2011. PD queries surpassed 1,000,000 per month, of which 300,000 may be attributable to the Great Recession. A one percentage point increase in mortgage delinquencies and foreclosures was associated with a 16% (95%CI, 9-24) increase in PD queries one-month, and 11% (95%CI, 3-18) four months later, in reference to a pre-Great Recession mean. Unemployment and underemployment had similar associations half and one-quarter the intensity. "Anxiety disorder", "what is depression", "signs of depression", "depression symptoms", and "symptoms of depression" were the queries exhibiting the strongest associations with mortgage delinquencies and foreclosures, unemployment or underemployment. Housing prices and S&P 500 trends were not associated with PD queries. A non-traditional measure of PD was used. It is unclear if actual clinically significant depression or anxiety increased during the Great Recession. Alternative explanations for strong associations between the Great Recession and PD queries, such as media, were explored and rejected. Because the economy is constantly changing, this work not only provides a snapshot of recent associations between the economy and PD queries but also a framework and toolkit for real-time surveillance going forward. Health resources, clinician screening patterns, and policy debate may be informed by changes in PD query

    The mutation of the spatacsin gene is the single most common cause of autosomal recessive hereditary spastic paraplegia with thin corpus callosum. Common clinical, pathological and genetic features between amyotrophic lateral sclerosis and hereditary spastic paraplegia motivated us to investigate 25 families with autosomal recessive juvenile amyotrophic lateral sclerosis and long-term survival for mutations in the spatascin gene. The inclusion criterion was a diagnosis of clinically definite amyotrophic lateral sclerosis according to the revised El Escorial criteria. The exclusion criterion was a diagnosis of hereditary spastic paraplegia with thin corpus callosum in line with an established protocol. Additional pathological and genetic evaluations were also performed. Surprisingly, 12 sequence alterations in the spatacsin gene (one of which is novel, IVS30 + 1 G > A) were identified in 10 unrelated pedigrees with autosomal recessive juvenile amyotrophic lateral sclerosis and long-term survival. The countries of origin of these families were Italy, Brazil, Canada, Japan and Turkey. The variants seemed to be pathogenic since they co-segregated with the disease in all pedigrees, were absent in controls and were associated with amyotrophic lateral sclerosis neuropathology in one member of one of these families for whom central nervous system tissue was available. Our study indicates that mutations in the spatascin gene could cause a much wider spectrum of clinical features than previously recognized, including autosomal recessive juvenile amyotrophic lateral sclerosis.

    The recent recession had a profound effect on all sectors of the US economy, including health care. We examined how private hospitals fared through the recession and considered how changes in their financial health may affect their ability to respond to future industry challenges. We categorized 2,971 private short-term general medical or surgical hospitals (both nonprofit and for-profit) according to their pre-recession financial health and safety-net status, and we examined their operational status changes and operating and total financial margins during 2006-11. We found that hospitals that were financially weak before the recession remained so during and after the recession. The total margins of nonprofit hospitals (both safety-net and other institutions) declined in 2008 but returned to their pre-recession levels by 2011. The recession did not create additional fiscal pressure on hospitals that were previously financially weak or in safety-net roles. However, both groups continue to have notable financial deficiencies that could limit their abilities to meet the growing demands on the industry.

  8. The Great American Recession and forgone healthcare: Do widened disparities between African-Americans and Whites remain?

    During the Great Recession in America, African-Americans opted to forgo healthcare more than other racial/ethnic groups. It is not understood whether disparities in forgone care returned to pre-recession levels. Understanding healthcare utilization patterns is important for informing subsequent efforts to decrease healthcare disparities. Therefore, we examined changes in racial disparities in forgone care before, during, and after the Great Recession. Data were pooled from the 2006-2013 National Health Interview Survey. Forgone medical, mental, and prescription care due to affordability were assessed among African-Americans and Whites. Time periods were classified as: pre-recession (May 2006-November 2007), early recession (December 2007-November 2008), late recession (December 2008-May 2010) and post-recession (June 2010-December 2013). Multivariable logistic regressions of race, interacted with time periods, were used to identify disparities in forgone care controlling for other demographics, health insurance coverage, and having a usual place for medical care across time periods. Adjusted Wald tests were performed to identify significant changes in disparities across time periods. The sample consisted of 110,746 adults. African-Americans were more likely to forgo medical care during the post- recession compared to Whites (OR = 1.16, CI = 1.06, 1.26); changes in foregone medical care disparities were significant in that they increased in the post-recession period compared to the pre-recession (OR = 1.17, CI = 1.08, 1.28 and OR = 0.89, CI = 0.77, 1.04, respectively, adjusted Wald Test p-value Great Recession and may be a result of outstanding issues related to healthcare access, cost, and quality. While health insurance is an important component of access to care, it alone should not be expected to remove these disparities due to other financial constraints. Additional strategies are necessary to close remaining gaps in care widened by the Great Recession.

    There has been a substantial rise in 'economic suicides' in the Great Recessions afflicting Europe and North America. We estimate that the Great Recession is associated with at least 10 000 additional economic suicides between 2008 and 2010. A critical question for policy and psychiatric practice is whether these suicide rises are inevitable. Marked cross-national variations in suicides in the recession offer one clue that they are potentially avoidable. Job loss, debt and foreclosure increase risks of suicidal thinking. A range of interventions, from upstream return-to-work programmes through to antidepressant prescriptions may help mitigate suicide risk during economic downturn. Royal College of Psychiatrists.

  12. Recession-based hydrological models for estimating low flows in ungauged catchments in the Himalayas

    2004-01-01

    Full Text Available The Himalayan region of Nepal and northern India experiences hydrological extremes from monsoonal floods during July to September, when most of the annual precipitation falls, to periods of very low flows during the dry season (December to February. While the monsoon floods cause acute disasters such as loss of human life and property, mudslides and infrastructure damage, the lack of water during the dry season has a chronic impact on the lives of local people. The management of water resources in the region is hampered by relatively sparse hydrometerological networks and consequently, many resource assessments are required in catchments where no measurements exist. A hydrological model for estimating dry season flows in ungauged catchments, based on recession curve behaviour, has been developed to address this problem. Observed flows were fitted to a second order storage model to enable average annual recession behaviour to be examined. Regionalised models were developed, using a calibration set of 26 catchments, to predict three recession curve parameters: the storage constant; the initial recession flow and the start date of the recession. Relationships were identified between: the storage constant and catchment area; the initial recession flow and elevation (acting as a surrogate for rainfall; and the start date of the recession and geographic location. An independent set of 13 catchments was used to evaluate the robustness of the models. The regional models predicted the average volume of water in an annual recession period (1st of October to the 1st of February with an average error of 8%, while mid-January flows were predicted to within ±50% for 79% of the catchments in the data set.

Hydraulically, it is the most complex phase and therefore difficult to predict in mathematical treatments. To obtain the recession phase, it is necessary to determine the time at which water advances over the soil surface to specific points, called stations, over the area and then record the time at which it disappears. Observing the passage of the recessive front through the measuring stations along the furrows as a function of time defines the recession curve. Using field data obtained by Ramsey (1976 and by the Department of Agriculture and Chemical Engineering, University of Colorado (1980, in three different farms:  Horticulture, Stieben e Benson. This work aimed to study the effect of the recession time on the infiltrated profile in surface irrigation.

    males in this strain. The factor responsible for spinosad resistance in the strain is unknown, but previous studies suggest a role of cytochrome P450s for detoxification of spinosad. Sex determination in the housefly is controlled by a male-determining factor (M), either located on the Y chromosome......BACKGROUND The housefly, Musca domestica L., is a global pest and has developed resistance to most insecticides applied for its control. The insecticide spinosad plays an important role in housefly control. Females of the Danish housefly strain 791spin are threefold more resistant to spinosad than...... of resistance to spinosad. Sex determination in 791spin is due to a male factor on autosome 3. CONCLUSIONS The most likely explanation for the differentiation of spinosad resistance between males and females is a recessive spinosad resistance factor on autosome III. © 2013 Society of Chemical Industry...

    To compare young children's different intensity physical activity (PA) levels in physical education, recess and exergaming programs. Participants were 140 first and second grade children (73 girls; Meanage= 7.88 years). Beyond the daily 20-minute recess, participants attended 75-minute weekly physical education classes and another 75-minute weekly exergaming classes. Children's PA levels were assessed by ActiGraph GTX3 accelerometers for 3 sessions in the 3 programs. The outcome variables were percentages of time spent in sedentary, light PA and moderate-to-vigorous PA (MVPA). There were significant main effects for program and grade, and an interaction effect for program by grade. Specifically, children's MVPA in exergaming and recess was higher than in physical education. The 2nd-grade children demonstrated lower sedentary behavior and MVPA than the first-grade children during recess; less light PA in both recess and exergaming than first-grade children; and less sedentary behavior but higher MVPA in exergaming than first-grade children. Young children generated higher PA levels in recess and exergaming as compared with physical education. Hence, other school-based PA programs may serve as essential components of a comprehensive school PA program. Implications are provided for educators and health professionals.

    Jasmine L Travers

    Full Text Available During the Great Recession in America, African-Americans opted to forgo healthcare more than other racial/ethnic groups. It is not understood whether disparities in forgone care returned to pre-recession levels. Understanding healthcare utilization patterns is important for informing subsequent efforts to decrease healthcare disparities. Therefore, we examined changes in racial disparities in forgone care before, during, and after the Great Recession.Data were pooled from the 2006-2013 National Health Interview Survey. Forgone medical, mental, and prescription care due to affordability were assessed among African-Americans and Whites. Time periods were classified as: pre-recession (May 2006-November 2007, early recession (December 2007-November 2008, late recession (December 2008-May 2010 and post-recession (June 2010-December 2013. Multivariable logistic regressions of race, interacted with time periods, were used to identify disparities in forgone care controlling for other demographics, health insurance coverage, and having a usual place for medical care across time periods. Adjusted Wald tests were performed to identify significant changes in disparities across time periods.The sample consisted of 110,746 adults. African-Americans were more likely to forgo medical care during the post- recession compared to Whites (OR = 1.16, CI = 1.06, 1.26; changes in foregone medical care disparities were significant in that they increased in the post-recession period compared to the pre-recession (OR = 1.17, CI = 1.08, 1.28 and OR = 0.89, CI = 0.77, 1.04, respectively, adjusted Wald Test p-value < 0.01. No changes in disparities were seen in prescription and mental forgone care.A persistent increase in forgone medical care disparities existed among African-Americans compared to Whites post-Great Recession and may be a result of outstanding issues related to healthcare access, cost, and quality. While health insurance is an important component of access

    2017-04-01

    Full Text Available Purpose The purpose of this study was to measure the axillary recess (AR thickness in an asymptomatic shoulder by using ultrasonography (US and to analyze the factors affecting it. Methods We recruited 141 patients (52 males; 89 females; age, 57.7±9.9 years with unilateral shoulder pain and performed US on the unaffected shoulder. Two physiatrists measured the AR thickness of the unaffected shoulder independently. All patients were examined in an upright sitting position with 90° shoulder abduction. The ultrasonographic transducer was placed longitudinally on the mid-axillary line and along the long axis of the humeral shaft. The factors affecting the AR thickness values were analyzed, and intra-class correlation coefficients were used for assessing the reproducibility of each measurement. Results The intrarater reliability values for the two physiatrists were 0.98 and 0.96, respectively. The inter-rater reliability of the mean AR thickness measurements was 0.91. The mean AR thickness in all subjects, males, and females was 2.8±0.6 mm, 3.1±0.6 mm, and 2.6±0.5 mm (P<0.01, respectively. No difference between the left and the right sides (males, P=0.086; females, P=0.535 or between the dominant and the non-dominant sides (males, P=0.173; female, P=0.244 was found. The AR thickness correlated positively with the height (r=0.313, P<0.01 and the weight (r=0.319, P<0.01.

  3. Recession-based hydrological models for estimating low flows in ungauged catchments in the Himalayas

    Science.gov (United States)

    Rees, H. G.; Holmes, M. G. R.; Young, A. R.; Kansakar, S. R.

    The Himalayan region of Nepal and northern India experiences hydrological extremes from monsoonal floods during July to September, when most of the annual precipitation falls, to periods of very low flows during the dry season (December to February). While the monsoon floods cause acute disasters such as loss of human life and property, mudslides and infrastructure damage, the lack of water during the dry season has a chronic impact on the lives of local people. The management of water resources in the region is hampered by relatively sparse hydrometerological networks and consequently, many resource assessments are required in catchments where no measurements exist. A hydrological model for estimating dry season flows in ungauged catchments, based on recession curve behaviour, has been developed to address this problem. Observed flows were fitted to a second order storage model to enable average annual recession behaviour to be examined. Regionalised models were developed, using a calibration set of 26 catchments, to predict three recession curve parameters: the storage constant; the initial recession flow and the start date of the recession. Relationships were identified between: the storage constant and catchment area; the initial recession flow and elevation (acting as a surrogate for rainfall); and the start date of the recession and geographic location. An independent set of 13 catchments was used to evaluate the robustness of the models. The regional models predicted the average volume of water in an annual recession period (1st of October to the 1st of February) with an average error of 8%, while mid-January flows were predicted to within ±50% for 79% of the catchments in the data set.

    In this study, we evaluate if moving recess before lunch has an effect on the amount of fruits and vegetables elementary school students eat as part of their school-provided lunch. Participants were 1st-6th grade students from three schools that switched recess from after to before lunch and four similar schools that continued to hold recess after lunch. We collected data for an average of 14 days at each school (4 days during spring 2011, May 3 through June 1, 2011 and 9 days during fall 2011, September 19 through November 11, 2011). All of the schools were in Orem, UT. Data was collected for all students receiving a school lunch and was based on observational plate waste data. We find that moving recess before lunch increased consumption of fruits and vegetables by 0.16 servings per child (a 54% increase) and increased the fraction of children eating at least one serving of fruits or vegetables by 10 percentage points (a 45% increase). In contrast, the schools in our control group actually experienced a small reduction in fruit and vegetable consumption during the same time period. Our results show the benefits of holding recess before lunch and suggest that if more schools implement this policy, there would be significant increases in fruit and vegetable consumption among students who eat school lunch as part of the National School Lunch Program.

    Facilitators and barriers to recess physical activity are not well understood. To date, research on recess physical activity has predominantly focused on quantitative measures typically focusing on a narrow set of predefined factors, often constructed by adults. To really understand the factors...... 11–12-year-old children. The socio-ecological model was used as the overall theoretical framework. Twelve factors were identified as influencing the children’s recess physical activity: bodily self-esteem and ability; gender; gendered school culture; peer influence; conflicts and exclusion; space...... and place experiences; lack of play facilities; outdoor play policy; use of electronic devices; recess duration; organised activities; and weather. These factors were located within different layers of the socio-ecological model, but were interdependent. The findings speak for implementing a combination...

  7. Did the Great Recession increase suicides in the USA? Evidence from an interrupted time-series analysis.

    Harper, Sam; Bruckner, Tim A

    2017-07-01

    Research suggests that the Great Recession of 2007-2009 led to nearly 5000 excess suicides in the United States. However, prior work has not accounted for seasonal patterning and unique suicide trends by age and gender. We calculated monthly suicide rates from 1999 to 2013 for men and women aged 15 and above. Suicide rates before the Great Recession were used to predict the rate during and after the Great Recession. Death rates for each age-gender group were modeled using Poisson regression with robust variance, accounting for seasonal and nonlinear suicide trajectories. There were 56,658 suicide deaths during the Great Recession. Age- and gender-specific suicide trends before the recession demonstrated clear seasonal and nonlinear trajectories. Our models predicted 57,140 expected suicide deaths, leading to 482 fewer observed than expected suicides (95% confidence interval -2079, 943). We found little evidence to suggest that the Great Recession interrupted existing trajectories of suicide rates. Suicide rates were already increasing before the Great Recession for middle-aged men and women. Future studies estimating the impact of recessions on suicide should account for the diverse and unique suicide trajectories of different social groups. Copyright © 2017 Elsevier Inc.

    Background Fluctuations in the national economy shape labour market opportunities and outcomes, which in turn may influence the accumulation of cognitive reserve. This study examines whether economic recessions experienced in early and mid-adulthood are associated with later-life cognitive function. Method Data came from 12,020 respondents in 11 countries participating in the Survey of Health, Ageing and Retirement in Europe (SHARE). Cognitive assessments in 2004/5 and 2006/7 were linked to complete work histories retrospectively collected in 2008/9, and to historical annual data on fluctuations in Gross Domestic Product (GDP) per capita for each country. Controlling for confounders, we assessed whether recessions experienced at ages 25-34, 35-44 and 45-49 were associated with cognitive function at ages 50-74. Results Among men, each additional recession at ages 45-49 was associated with worse cognitive function at ages 50-74 (b = -0.06, Confidence Interval [CI] -0.11, -0.01). Among women, each additional recession at ages 25-44 was associated with worse cognitive function at ages 50-74 (b25-34 = -0.03, CI -0.04, -0.01; b35-44= -0.02, CI -0.04, -0.00). Among men, recessions at ages 45-49 influenced risk of being laid-off, whereas among women, recessions at ages 25-44 led to working part-time and higher likelihood of downward occupational mobility, which were all predictors of worse later-life cognitive function. Conclusions Recessions at ages 45-49 among men and 25-44 among women are associated with later-life cognitive function, possibly via more unfavourable labour market trajectories. If replicated in future studies, findings may indicate that policies that ameliorate the impact of recessions on labour market outcomes may promote later-life cognitive function. PMID:24258197

  10. STRATEGIES FOR SUPERIOR PERFORMANCE IN RECESSIONS: PRO OR COUNTER-CYCLICAL?

    Directory of Open Access Journals (Sweden)

    Claudio Ramos Conti

    2015-04-01

    Full Text Available Recessions are recurring events in which most firms suffer severe impacts while others are less affected or may even prosper. Strategic management has made little progress in understanding such performance differences. In a scenario of decreased demand, intensified competition, and higher uncertainty, most firms try to survive by pro-cyclically cutting costs and investments. But firms could take advantage of undervalued resources in the market to counter-cyclically invest in new business opportunities to overtake competitors. We survey Brazilian firms in various industries about the 2008-2009 recession and analyze data using PLS-SEM. We find that while most firms pro-cyclically reduce costs and investments in recessions, a counter-cyclical strategy of investing in opportunities created by changes in the market enables superior performance. Most successful are firms with a propensity to recognize opportunities, an entrepreneurial orientation to invest, and the flexibility to efficiently implement investments.

  11. Metabolic Syndrome Risks Following the Great Recession in Rural Black Young Adults.

    2017-09-06

    Some of the country's highest rates of morbidity and mortality from cardiovascular disease are found in lower-income black communities in the rural Southeast. Research suggests these disparities originate in the early decades of life, and partly reflect the influence of broader socioeconomic forces acting on behavioral and biological processes that accelerate cardiovascular disease progression. However, this hypothesis has not been tested explicitly. Here, we examine metabolic syndrome (MetS) in rural black young adults as a function of their family's economic conditions before and after the Great Recession. In an ongoing prospective study, we followed 328 black youth from rural Georgia, who were 16 to 17 years old when the Great Recession began. When youth were 25, we assessed MetS prevalence using the International Diabetes Federation's guidelines. The sample's overall MetS prevalence was 18.6%, but rates varied depending on family economic trajectory from before to after the Great Recession. MetS prevalence was lowest (10.4%) among youth whose families maintained stable low-income conditions across the Recession. It was intermediate (21.8%) among downwardly mobile youth (ie, those whose families were lower income before the Recession, but slipped into poverty). The highest MetS rates (27.5%) were among youth whose families began the Recession in poverty, and sank into more meager conditions afterwards. The same patterns were observed with 3 alternative MetS definitions. These patterns suggest that broader economic forces shape cardiometabolic risk in young blacks, and may exacerbate disparities already present in this community. © 2017 The Authors.

  12. Inter-seasonal variability in baseflow recession rates: The role of aquifer antecedent storage in central California watersheds

    Science.gov (United States)

    Bart, Ryan; Hope, Allen

    2014-11-01

    Baseflow recession rates vary inter-seasonally in many watersheds. This variability is generally associated with changes in evapotranspiration; however, an additional and less studied control over inter-seasonal baseflow recession rates is the effect of aquifer antecedent storage. Understanding the role of aquifer antecedent storage on baseflow recession rates is crucial for Mediterranean-climate regions, where seasonal asynchronicity of precipitation and energy levels produces large inter-seasonal differences in aquifer storage. The primary objective of this study was to elucidate the relation between aquifer antecedent storage and baseflow recession rates in four central California watersheds using antecedent streamflow as a surrogate for watershed storage. In addition, a parsimonious storage-discharge model consisting of two nonlinear stores in parallel was developed as a heuristic tool for interpreting the empirical results and providing insight into how inter-seasonal changes in aquifer antecedent storage may affect baseflow recession rates. Antecedent streamflow cumulated from the beginning of the wateryear was found to be the strongest predictor of baseflow recession rates, indicating that inter-seasonal differences in aquifer storage are a key control on baseflow recession rates in California watersheds. Baseflow recession rates and antecedent streamflow exhibited a negative power-law relation, with baseflow recession rates decreasing by up to two orders of magnitude as antecedent streamflow levels increased. Inference based on the storage-discharge model indicated that the dominant source of recession flow shifted from small, rapid response aquifers at the beginning of the wet season to large, seasonal aquifers as the wet season progressed. Aquifer antecedent storage in California watersheds should be accounted for along with evapotranspiration when characterizing baseflow recession rates.

    Full Text Available Background: The paper gives an update to earlier analysis considering youth poverty and transition to adulthood, which is timely given the economic crisis engulfing many countries in Europe. Whereas the crisis is affecting young people in particular, there is also a certain degree of variation across Europe. Objective: We document the short-term consequences of the current recession on the transition to adulthood of young Europeans, focusing on two main cornerstones in the transition to adulthood: economic independence and residential autonomy. Methods: We use a combination of OECD Employment Statistics for 2012 and micro-level data from the European Union Statistics on Income and Living Conditions (EU-SILC for the period 2005-2011 for 24 countries. Results: We document an increase in economic hardship experienced by young adults in several European countries during the recession, which is starting to translate into higher rates of co-residence with parents, hence delaying the process of leaving home and gaining economic independence. Conclusions: The way countries are reacting to the recession is not yet clear-cut, but economic uncertainty and deprivation is on the rise in those countries hardest hit, which is likely to delay the key markers of transition to adulthood.

    2016-01-01

    Abstract Background: Mass unemployment in Europe is endemic, especially among the young. Does it cause mortality? Methods: We analyzed long-term effects of unemployment occurring during the deep Swedish recession 1992–96. Mortality from all and selected causes was examined in the 6-year period after the recession among those employed in 1990 (3.4 million). Direct health selection was analyzed as risk of unemployment by prior medical history based on all hospitalizations 1981–91. Unemployment effects on mortality were estimated with and without adjustment for prior social characteristics and for prior medical history. Results: A prior circulatory disease history did not predict unemployment; a history of alcohol-related disease or suicide attempts did, in men and women. Unemployment predicted excess male, but not female, mortality from circulatory disease, both ischemic heart disease and stroke, and from all causes combined, after full adjustment. Adjustment for prior social characteristics reduced estimates considerably; additional adjustment for prior medical history did not. Mortality from external and alcohol-related causes was raised in men and women experiencing unemployment, after adjustment for social characteristics and medical history. For the youngest birth cohorts fully adjusted alcohol mortality HRs were substantial (male HR = 4.44; female HR = 5.73). The effect of unemployment on mortality was not uniform across the population; men, those with a low education, low income, unmarried or in urban employment were more vulnerable. Conclusions: Direct selection by medical history explains a modest fraction of any increased mortality risk following unemployment. Mass unemployment imposes long-term mortality risk on a sizeable segment of the population. PMID:27085193

    Full Text Available Introduction. Gingival recession is a displacement of gingival margin apically to cementenamel junction. Objective. The aim of this study was to compare the results achieved with two different surgical procedures used in gingival recession treatment. Methods. Ten patients with bilateral buccal recession on maxillary canines or premolars were included in the study. Professional teeth cleaning was performed before surgery. Recession on the experimental side was treated with connective tissue graft in combination with coronally advanced, split thickness flap (tunnel technique. Control side recession was treated with connective tissue graft in combination with trapezoidal coronally advanced, full thickness flap. Coin toss was used for side decision. The following parameters were evaluated before surgery and 6 months post-op: Vertical Recession Dimension, Clinical Attachment Level, Apico-coronal width of the keratinized tissue, Healing index (Laundry, RES index, and Patient evaluation of esthetic results. Student’s t-test was used for statistical analysis. Results. Six months after surgery, mean root coverage was 91.5±14.1% and 90.1±14.6% on the experimental and on the control side, respectively. RES index, Healing index (Laundry and Patient Subjective evaluation of esthetic results showed significantly better results (p≤0.05. Conclusion. Both surgical procedures produce highly successful clinical results based on evaluated parameters, but this tunnel technique provides significantly better esthetic results.

    Ormerod and Mounfield [P. Ormerod, C. Mounfield, Power law distribution of duration and magnitude of recessions in capitalist economies: Breakdown of scaling, Physica A 293 (2001) 573] and Ausloos et al. [M. Ausloos, J. Mikiewicz, M. Sanglier, The durations of recession and prosperity: Does their distribution follow a power or an exponential law? Physica A 339 (2004) 548] have independently analyzed the duration of recessions for developed countries through the evolution of the GDP in different time windows. It was found that there is a power law governing the duration distribution. We have analyzed data collected from 19 Latin American countries in order to observe whether such results are valid or not for developing countries. The case of prosperity years is also discussed. We observe that the power law of recession time intervals, see Ref. [1], is valid for Latin American countries as well. Thus an interesting point is discovered: the same scaling time is found in the case of recessions for the three data sets (ca. 1 year), and this could represent a universal feature. Other time scale parameters differ significantly from each other.

  19. Financial and Real Sector Leading Indicators of Recessions in Brazil Using Probabilistic Models

    Directory of Open Access Journals (Sweden)

    Fernando Nascimento de Oliveira

    Full Text Available We examine the usefulness of various financial and real sector variables to forecast recessions in Brazil between one and eight quarters ahead. We estimate probabilistic models of recession and select models based on their outof-sample forecasts, using the Receiver Operating Characteristic (ROC function. We find that the predictive out-of-sample ability of several models vary depending on the numbers of quarters ahead to forecast and on the number of regressors used in the model specification. The models selected seem to be relevant to give early warnings of recessions in Brazil.

    Full Text Available In October 2008, Iceland experienced the fastest and deepest financial crisis recorded in modern times when all three major banks went bankrupt in less than 2 weeks. The purpose of this follow-up study is to examine potential changes in participation in 12 different gambling types and in problem gambling before (time 1; year 2007 and after (time 2; year 2011 the economic collapse in 2008. The time between the first and second wave of data collection was 3.5 years. In total, 1,531 participants took part in the study, 688 males and 843 females. There was a considerable increase in past year gambling behavior from 2007 to 2011, mostly due to increased participation in lotto (National lotto and Viking lotto but also in bingo, monthly lotteries (class lotteries with at least monthly draw and scratch tickets. Only EGMs (electronic gaming machines participation declined significantly between the two timepoints. Examining past year problematic gambling figures revealed that there were no changes in the prevalence figures between the year 2007 (1.2% and 2011 (1.1%. Further examination revealed that those who reported financial difficulties due to the recession were more likely to buy lotto- or scratch tickets during the recession than those who were not financially affected by the crisis. These findings remained after controlling for background variables and baseline gambling activity (gambling in 2007. Overall, the findings of the follow-up study suggest that when people are experiencing financial difficulties during economic recessions, the possibility to improve their financial situation by winning large jackpots with low initial stakes becomes more enticing.

    Full Text Available Introduction Root coverage supported with complete regeneration of lost periodontal tissues represents the ultimate goal of gingival recession treatment. Objective This study was designed to evaluate clinical effectiveness of platelet rich plasma gel (PRP with connective tissue graft (CTG in the treatment of gingival recession. METHOD 15 gingival recessions Miller class I or II were treated with CTG and PRP (group PRP. Connective tissue graft was harvested from the premolar region using trap door technique. After elevation of the flap, the regional bone and root surface were smeared with activated PRP gel. CTG was also irrigated with PRP gel before placement over the exposed root surface and local bone. Fixed CTG was covered with a coronally advanced flap. The same number of gingival recessions were treated with CTG in combination with the coronally advanced flap with no PRP gel (group TVT. Clinical recordings included recession depth (RD, probing depth (PD, clinical attachment level (CAL and keratinized tissue width (KT before and 1 year after mucogingival surgical treatment. Results Mean value of RD was significantly decreased from 4.93±0.86 mm to 0.60±0.37 (p<0.01 with CTG and PRP and from 4.76±0.74 mm to 0.63±0.29 mm (p<0.01 in CTG group. This difference was not statistically significant. Results of the keratinized tissue width showed significant increase from 0.88± 0.30 mm presurgery to 3.78±0.49 mm (p<0.01 six months after treatment in PRP group and from 0.90±0.34 mm to 3.15±0.41 in TVT group (p<0.01. This difference was statistically significant (p>0.05. No statistically significant differences were observed between treatment groups in CAL and PD. Conclusion Clinical results validate both procedures as effective and highly predictable surgical techniques in solving gingival recession problem. Histological evaluation may confirm advantage of PRP use related to regeneration of periodontal tissues. .

    The interaction of surface to subsurface water is an important issue for groundwater resources assessment and management. The influences of surface water to groundwater are mainly through the rainfall recharge, river recharge and discharge and other boundary sources. During a drought period, the interaction of river and groundwater may be one of the main sources of groundwater level recession. Therefore, this study explores the interaction of surface water to groundwater via the groundwater recession. During drought periods, the pumping and river interaction together are the main mechanisms causing the recession of groundwater level. In principle, larger gradient of the recession curve indicates more groundwater discharge and it is an important characteristic of the groundwater system. In this study, to avoid time-consuming manual analysis, the Python programming language is used to develop a statistical analysis model for exploring the groundwater recession information. First, the slopes of the groundwater level hydrograph at every time step were computed for each well. Then, for each well, the represented slope to each groundwater level was defined as the slope with 90% exceedance probability. The relationship between the recession slope and the groundwater level can then be obtained. The developed model is applied to Choushui River Alluvial Fan. In most wells, the results show strong positive correlations between the groundwater levels and the absolute values of the recession slopes.

  4. The estimation of risks from the induction of recessive mutations after exposure to ionising radiation

    International Nuclear Information System (INIS)

    Searle, A.G.; Edwards, J.H.

    1986-01-01

    Induced recessive mutations can cause harm by (1) partnership with a defective allele already established in the population; (2) partnership with another recessive mutation induced at the same locus; (3) the formation of homozygous descendants, that is, identify by descent; and (4) heterozygous effects. Calculations based on a combination of data from observations on human populations and from mouse experiments suggest that an extra genetically significant dose of 1 cGy X or γ irradiation received by each parent in a stable population with a million liveborn offspring would induce up to 1200 extra recessive mutations. From partnership effects, about one extra case of recessive disease would be expected in the following 10 generations. Homozygosity resulting from identity by descent could not normally occur until the fourth generation after exposure but, on certain assumptions, about ten extra cases of recessive disease would be expected from this cause by the tenth generation. In the same period, about 250 recessive alleles would be eliminated in heterozygotes given 2.5% heterozygous disadvantage. These deleterious heterozygous effects should not be combined with those of dominants, as has been done in some previous risk estimates. It is considered unlikely that many radiation induced recessives would show heterozygous advantage. Certain dominants should be excluded from calculations of mutational risk because they are unlikely to be maintained by mutation. (author)

    The frequency of recessive sex-linked lethal mutations (RSLLM) and those realizing in embryogenesis of dominant lethals, which form in oo- and spermatogenesis of Drosophila and fly productivity under the effect of X-rays and N-nitroso-N methylourea (NMU), is studied. In the case of effect of both mutagens RSLLM form in spermatocytes with higher frequency as compared with oocytes. Dominant lethal mutations (DLM) during irradiation are also often registered in spermatocytes. NMU induces DLM in mitotic male cells with a very high frequency but is not effective during the effect on oocytes. When both mutagens affect males and X-rays affect females, the decrease of productivity is mainly conditioned by DLM. As NMU does not induce DLM in females realizing in embryogenesis but reduces productivity, a later lethal realization connected with their different nature is supposed. Differences in mole and female mutability found in the course of X-ray and NMU effect are discussed in connection with peculiarities of their mitotic cells and the nature of effect of mutagens applied [ru

    To assess gingival recession (GR) in manual and power toothbrush users and evaluate the relationship between GR and gingival abrasion scores (GA). This was an observational (cross-sectional), single-centre, examiner-blind study involving a single-brushing exercise, with 181 young adult participants: 90 manual brush users and 91 oscillating-rotating power brush users. Participants were assessed for GR and GA as primary response variables. Secondary response variables were the level of gingival inflammation, plaque score reduction and brushing duration. Pearson correlation was used to describe the relationship between number of recession sites and number of abrasions. Prebrushing (baseline) and post-brushing GA and plaque scores were assessed and differences analysed using paired tests. Two-sample t-test was used to analyse group differences; ancova was used for analyses of post-brushing changes with baseline as covariate. Overall, 97.8% of the study population had at least one site of ≥1 mm of gingival recession. For the manual group, this percentage was 98.9%, and for the power group, this percentage was 96.7% (P = 0.621). Post-brushing, the power group showed a significantly smaller GA increase than the manual group (P = 0.004); however, there was no significant correlation between number of recession sites and number of abrasions for either group (P ≥ 0.327). Little gingival recession was observed in either toothbrush user group; the observed GR levels were comparable. Lower post-brushing gingival abrasion levels were seen in the power group. There was no correlation between gingival abrasion as a result of brushing and the observed gingival recession following use of either toothbrush. © 2014 The Authors International Journal of Dental Hygiene Published by John Wiley & Sons Ltd.

  8. A historical perspective of the effect of the great recession on hospitals.

    Shortt, Janet

    2014-08-01

    At 18 months, the Great Recession of December 2007 to June 2009 is the longest recession since World War II. The recession led to soaring unemployment, resulting in loss of employment-based health insurance for millions of people. In addition to seeing increases in uninsured patients, hospitals experienced losses in their investment portfolios, which in turn increased bad debt, charity care, and uncompensated care nationwide. Hospital executives began to devise cost-cutting strategies to balance the rising debt, such as standardizing medical equipment, cutting staff positions, and delaying construction projects and capital expenditures as well as implementing value analysis strategies. The recession is officially over, and, although economic recovery has been slow and unemployment continues to be an issue, hospitals' net revenue started improving as of 2009 and hospital construction started increasing in 2010. Still, caution is warranted in the postrecession climate, because it is unknown what effects will be seen when the Baby Boomer generation begins using Medicare. Copyright © 2014 AORN, Inc.

  10. Impact of the economic recession on the European power sector's CO2 emissions

    2011-01-01

    This paper investigates the impact of the economic recession on CO 2 emissions in the European power sector, during the years 2008 and 2009. Three main determinants of the power sector's emissions are identified: the demand for electricity, the CO 2 price, and fuel prices. A counterfactual scenario has been set up for each of these, i.e., what these parameters would have been if not affected by the recession. A simulation model of the European power sector is then employed, comparing a historical reference simulation (taking the parameters as actually occurred) with the counterfactual scenarios. The lower electricity demand (due to the recession) is shown to have by far the largest impact, accounting for an emission reduction of about 175 Mton. The lower CO 2 price (due to the recession) resulted in an increase in emissions by about 30 Mton. The impact of fuel prices is more difficult to retrieve; an indicative reduction of about 17 Mton is obtained, mainly as a consequence of the low gas prices in 2009. The simulated combined impact of the parameters results in an emission reduction of about 150 Mton in the European power sector over the years 2008 and 2009 as a consequence of the recession. - Research highlights: → CO 2 emissions are simulated for the European power sector. → Emissions reduced drastically because of the economic recession in 2008 and 2009. → Lower electricity demand had highest impact and accounts for reduction of about 175 Mton. → Impact of different CO 2 and fuel prices on emissions is more limited.

    Associations between economic conditions and health are usually derived from cost-intensive surveys that are intermittently collected with nonspecific measures (i.e., self-rated health). This study identified how precise health concerns changed during the U.S. Great Recession analyzing Google search queries to identify the concern by the query content and their prevalence by the query volume. Excess health concerns were estimated during the Great Recession (December 2008 through 2011) by comparing the cumulative difference between observed and expected (based on linear projections from pre-existing trends) query volume for hundreds of individual terms. As performed in 2013, the 100 queries with the greatest excess were ranked and then clustered into themes based on query content. The specific queries with the greatest relative excess were stomach ulcer symptoms and headache symptoms, respectively, 228% (95% CI=35, 363) and 193% (95% CI=60, 275) greater than expected. Queries typically involved symptomology (i.e., gas symptoms) and diagnostics (i.e., heart monitor) naturally coalescing into themes. Among top themes, headache queries were 41% (95% CI=3, 148); hernia 37% (95% CI=16, 142); chest pain 35% (95% CI=6, 313); and arrhythmia 32% (95% CI=3, 149) greater than expected. Pain was common with back, gastric, joint, and tooth foci, with the latter 19% (95% CI=4, 46) higher. Among just the top 100, there were roughly 205 million excess health concern queries during the Great Recession. Google queries indicate that the Great Recession coincided with substantial increases in health concerns, hinting at how population health specifically changed during that time. © 2013 Published by American Journal of Preventive Medicine on behalf of American Journal of Preventive Medicine.

    We present a linkage analysis and a clinical update on a previously reported family with X-linked recessive panhypopituitarism, now in its fourth generation. Affected members exhibit variable degrees of hypopituitarism and mental retardation. The markers DXS737 and DXS1187 in the q25-q26 region of the X chromosome showed evidence for linkage with a peak LOD score (Zmax) of 4.12 at zero recombination fraction (theta(max) = 0). An apparent extra copy of the marker DXS102, observed in the region of the disease gene in affected males and heterozygous carrier females, suggests that a segment including this marker is duplicated. The gene causing this disorder appears to code for a dosage-sensitive protein central to development of the pituitary. Images Figure 2 PMID:9106538

    Objectives. This study assessed possible associations between recessions and changes in the magnitude of social disparities in foregone health care, building on previous studies that have linked recessions to lowered health care use. Methods. Data from the 2006 to 2010 waves of the National Health Interview Study were used to examine levels of foregone medical, dental and mental health care and prescribed medications. Differences by race/ethnicity and education were compared before the Great Recession of 2007 to 2009, during the early recession, and later in the recession and in its immediate wake. Results. Foregone care rose for working-aged adults overall in the 2 recessionary periods compared with the pre-recession. For multiple types of pre-recession care, foregoing care was more common for African Americans and Hispanics and less common for Asian Americans than for Whites. Less-educated individuals were more likely to forego all types of care pre-recession. Most disparities in foregone care were stable during the recession, though the African American–White gap in foregone medical care increased, as did the Hispanic–White gap and education gap in foregone dental care. Conclusions. Our findings support the fundamental cause hypothesis, as even during a recession in which more advantaged groups may have had unusually high risk of losing financial assets and employer-provided health insurance, they maintained their relative advantage in access to health care. Attention to the macroeconomic context of social disparities in health care use is warranted. PMID:24328647

    2017-02-01

    Full Text Available The financial crises of 2007-2008, caused wide-spread falling output and unemployment, in the affected countries and also globally. The severity of the recession was such that it was called the “Great Recession”. As a result of an increase in demand from China and India, at the same time, oil prices rose significantly. The empirical results from this study show that oil price changes negatively affected global growth rate in the 1970s but not in the 1990s and 2000s. These results suggest that the Great Recession in 2008 that initiated by the financial crises, was independent of a significant rise in oil prices.

    To assess the clinical and molecular genetic studies of patients with autosomal recessive retinitis pigmentosa associated with a mutation in the arrestin gene. Results of molecular genetic screening and case reports with DNA analysis and clinical features. University medical center. One hundred twenty anamnestically unrelated patients with autosomal recessive retinitis pigmentosa. DNA analysis was performed by single strand conformation polymorphism followed by nucleotide sequencing to search for a mutation in exon 11 of the arrestin gene. Clinical features were characterized by visual acuity slitlamp biomicroscopy, fundus examinations, fluorescein angiography, kinetic visual field testing, and electroretinography. We identified 3 unrelated patients with retinitis pigmentosa associated with a homozygous 1-base-pair deletion mutation in codon 309 of the arrestin gene designated as 1147delA. All 3 patients showed pigmentary retinal degeneration in the midperipheral area with or without macular involvement. Patient 1 had a sibling with Oguchi disease associated with the same mutation. Patient 2 demonstrated pigmentary retinal degeneration associated with a golden-yellow reflex in the peripheral fundus. Patients 1 and 3 showed features of retinitis pigmentosa without the golden-yellow fundus reflex. Although the arrestin 1147delA has been known as a frequent cause of Oguchi disease, this mutation also may be related to the pathogenesis of autosomal recessive retinitis pigmentosa. This phenomenon may provide evidence of variable expressivity of the mutation in the arrestin gene.

    Published studies on the association between the C677T and A1298C polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene and male infertility risk are controversial. To obtain a more precise evaluation, we performed a meta-analysis based on published case-control studies. We conducted an electronic search of PubMed, EMBASE, the Cochrane Library, the Web of Science, and the China Knowledge Resource Integrated Database for papers on MTHFR gene C677T and A1298C polymorphisms and male infertility risk. Pooled odds ratios (ORs) with 95% confidence intervals (95%CIs) were used to assess the strength of association in homozygote, heterozygote, dominant, recessive, and additive models. Statistical heterogeneity, test of publication bias, and sensitivity analysis were carried out using the STATA software (Version 13.0). Overall, 21 studies of C677T (4505 cases and 4024 controls) and 13 studies of A1298C (2785 cases and 3094 controls) were included in this meta-analysis. For C677T, the homozygote comparison results were OR = 1.629, 95%CI (1.215- 2.184), and the recessive model results were OR = 1.462 (1.155- 1.850). For A1298C, the homozygote comparison results were OR = 1.289 (1.029-1.616), and the recessive model results were OR = 1.288 (1.034-1.604). In conclusion, the current meta-analysis showed that the MTHFR C677T polymorphism was associated with a significantly increased male infertility risk in the Asian and overall populations, but not in the Caucasian population, and there was a significant association between the A1298C polymorphism and male infertility risk in the Asian, Caucasian, and overall groups.

    Abstract Anophthalmia is a rare ocular malformation. It is a genetically determined disorder and is typically associated with syndromes. However, sporadic nonsyndromic familial as well as non-familial cases of anophthalmia have also been reported. Non-syndromic familial cases are usually bilateral and have been attributed to autosomal recessive, autosomal dominant, and X-linked inheritance patterns. The authors hereby report a rare case of autosomal recessive unilateral anophthalmia in a patient with no other associated congenital anomaly. Patient was operated for craniopharyngioma. The clinical, radiological and intraoperative findings are discussed. PMID:27928292

With the objective of developing genic but non-coding microsatellite (GNMS markers for the rice (Oryza sativa L. genome, we characterized the frequency and relative distribution of microsatellite repeat-motifs in 18,935 predicted protein coding genes including 14,308 putative promoter sequences. Results We identified 19,555 perfect GNMS repeats with densities ranging from 306.7/Mb in chromosome 1 to 450/Mb in chromosome 12 with an average of 357.5 GNMS per Mb. The average microsatellite density was maximum in the 5' untranslated regions (UTRs followed by those in introns, promoters, 3'UTRs and minimum in the coding sequences (CDS. Primers were designed for 17,966 (92% GNMS repeats, including 4,288 (94% hypervariable class I types, which were bin-mapped on the rice genome. The GNMS markers were most polymorphic in the intronic region (73.3% followed by markers in the promoter region (53.3% and least in the CDS (26.6%. The robust polymerase chain reaction (PCR amplification efficiency and high polymorphic potential of GNMS markers over genic coding and random genomic microsatellite markers suggest their immediate use in efficient genotyping applications in rice. A set of these markers could assess genetic diversity and establish phylogenetic relationships among domesticated rice cultivar groups. We also demonstrated the usefulness of orthologous and paralogous conserved non-coding microsatellite (CNMS markers, identified in the putative rice promoter sequences, for comparative physical mapping and understanding of evolutionary and gene regulatory complexities among rice and other members of the grass family. The divergence between long-grained aromatics and subspecies japonica was estimated to be more recent (0.004 Mya compared to short

    The negative impacts of previous economic recessions on suicide rates have largely been attributed to rapid rises in unemployment in the context of inadequate social and work protection programmes. We have investigated trends in indicators of the 2008 economic recession and trends in suicide rates in England and Wales in men and women of working age (16–64 years old) for the period 2001–2011, before, during and after the economic recession, our aim was to identify demographic groups whose suicide rates were most affected. We found no clear evidence of an association between trends in female suicide rates and indicators of economic recession. Evidence of a halt in the previous downward trend in suicide rates occurred for men aged 16–34 years in 2006 (95% CI Quarter 3 (Q3) 2004, Q3 2007 for 16–24 year olds & Q1 2005, Q4 2006 for 25–34 year olds), whilst suicide rates in 35–44 year old men reversed from a downward to upward trend in early 2010 (95% CI Q4 2008, Q2 2011). For the younger men (16–34 years) this change preceded the sharp increases in redundancy and unemployment rates of early 2008 and lagged behind rising trends in house repossessions and bankruptcy that began around 2003. An exception were the 35–44 year old men for whom a change in suicide rate trends from downwards to upwards coincided with peaks in redundancies, unemployment and rises in long-term unemployment. Suicide rates across the decade rose monotonically in men aged 45–64 years. Male suicide in the most-to-medium deprived areas showed evidence of decreasing rates across the decade, whilst in the least-deprived areas suicide rates were fairly static but remained much lower than those in the most-deprived areas. There were small post-recession increases in the proportion of suicides in men in higher management/professional, small employer/self-employed occupations and fulltime education. A halt in the downward trend in suicide rates amongst men aged 16–34 years, may have begun

    Most severe forms of intellectual disability (ID) have specific genetic causes. Numerous X chromosome gene defects and disease-causing copy-number variants have been linked to ID and related disorders, and recent studies have revealed that sporadic cases are often due to dominant de novo mutations with low recurrence risk. For autosomal recessive ID (ARID) the recurrence risk is high and, in populations with frequent parental consanguinity, ARID is the most common form of ID. Even so, its elu...

    2017-11-01

    A new method was developed and implemented into an Excel Visual Basic for Applications (VBAs) algorithm utilizing trigonometry laws in an innovative way to overlap recession segments of time series and create master recession curves (MRCs). Based on a trigonometry approach, the algorithm horizontally translates succeeding recession segments of time series, placing their vertex, that is, the highest recorded value of each recession segment, directly onto the appropriate connection line defined by measurement points of a preceding recession segment. The new method and algorithm continues the development of methods and algorithms for the generation of MRC, where the first published method was based on a multiple linear/nonlinear regression model approach (Posavec et al. 2006). The newly developed trigonometry-based method was tested on real case study examples and compared with the previously published multiple linear/nonlinear regression model-based method. The results show that in some cases, that is, for some time series, the trigonometry-based method creates narrower overlaps of the recession segments, resulting in higher coefficients of determination R 2 , while in other cases the multiple linear/nonlinear regression model-based method remains superior. The Excel VBA algorithm for modeling MRC using the trigonometry approach is implemented into a spreadsheet tool (MRCTools v3.0 written by and available from Kristijan Posavec, Zagreb, Croatia) containing the previously published VBA algorithms for MRC generation and separation. All algorithms within the MRCTools v3.0 are open access and available free of charge, supporting the idea of running science on available, open, and free of charge software. © 2017, National Ground Water Association.

    OBJECTIVE: Male live births slightly exceed female live births by approximately 3%. The ratio of male to total live births is conventionally represented as M/F. Many factors have been shown to affect M/F, mainly privation, toxins, and stress, all of which reduce M/F. Population stress may be engendered by natural phenomena such as earthquakes and man-made events such as short wars, terrorist attacks, and contracting economies. This study was conducted to ascertain whether the onset of the "Gr...

    The purpose of this study is to describe recessive alleles in strictly dominant genes. Identifying recessive mutations in genes for which only dominant disease or risk alleles have been reported can expand our understanding of the medical relevance of these genes both phenotypically and mechanistically. The Saudi population is enriched for autozygosity, which enhances the homozygous occurrence of alleles, including pathogenic alleles in genes that have been associated only with a dominant inheritance pattern.Exome sequencing of patients from consanguineous families with likely recessive phenotypes was performed. In one family, the genotype of the deceased children was inferred from their parents due to lack of available samples.We describe the identification of 11 recessive variants (5 of which are reported here for the first time) in 11 genes for which only dominant disease or risk alleles have been reported. The observed phenotypes for these recessive variants were novel (e.g., FBN2-related myopathy and CSF1R-related brain malformation and osteopetrosis), typical (e.g., ACTG2-related visceral myopathy), or an apparently healthy state (e.g., PDE11A), consistent with the corresponding mouse knockout phenotypes.Our results show that, in the era of genomic sequencing and

    A family is described with presumed autosomal recessive inheritance in which three siblings developed a progressive neuropathy that combined limb weakness and severe distal sensory loss leading to prominent mutilating changes. Electrophysiological and nerve biopsy findings indicated an axonopathy. The disorder is therefore classifiable as type II hereditary motor and sensory neuropathy (HMSN II). The clinical features differ from those reported in previously described cases of autosomal recessive HMSN II. This disorder may therefore represent a new variant.

    2016-07-01

    The 2007/2008 financial crisis, and ensuing economic recession, had a direct negative effect on university-industry research cooperation in the OECD countries and other economies – it diminished the number of university-industry co-authored research publications (UICs) during the period 2008-13 by 7%. It also changed the relationship between national business expenditure on R&D and UIC output levels. Before the recession the relationship was negative, but became positive during the years 2008-2013. The few countries where business expenditure on R&D increased during recession saw UIC numbers rise. This moderating effect of the recession applies only to ‘domestic UICs’, where universities cooperated with business companies located in the same country. Micro-level research is needed to assess the contributing effects on large university-industry R&D consortia on both domestic and international collaboration patterns. (Author)

    Epidemiological evidence indicates an elevated risk for stroke among stressed persons, in general, and among individuals who have lost their job, in particular. We, therefore, tested the hypothesis that stroke accounted for a larger fraction of deaths during the Great Recession than expected from other deaths and from trends, cycles, and other forms of autocorrelation. Based on vital statistics death data from California spanning 132 months from January 2000 through December 2010, we found support for the hypothesis. These findings appear attributable to non-Hispanic white men, who experienced a 5% increase in their monthly odds of stroke-attributable death. Total mortality in this group, however, did not increase. Findings suggest that 879 deaths among older white men shifted from other causes to stroke during the 36 months following the start of the Great Recession. We infer the Great Recession may have affected social, biologic, and behavioral risk factors that altered the life histories of older white men in ways that shifted mortality risk toward stroke.

    2017-01-01

    Full Text Available This article considers representations of melancholia in post-Celtic Tiger Irish literature. By situating their post-recession fictions in “ghost estates,” or largely uninhabited housing developments, Donal Ryan and Tana French present neoliberally-inflected varieties of melancholia for their contemporary readers to contemplate. The settings of the ghost estates – and the accompanying supernatural elements to the texts – call to mind ghosts of Ireland’s past and legacies of recent economically unsound policies, spurring the reader to think about the imagined loss of futurity that accompanied the Irish economic crash. “Ghost stories for ghost estates,” then, represent an important contribution to the growing field of post-recession Irish literature.

    Full Text Available Canine medial patellar luxation (MPL is a very common orthopedic disease in small animals. Because the pathophysiology of this disease involves various pathways, the surgical techniques and results vary according to the veterinarian. Further, the landmark for block recession is not completely clear. We retrospectively evaluated 75 dogs (107 limbs with MPL in whom our landmark for block recession was used from July 2008 to May 2013. Information regarding the breed, age, sex, body weight, body condition score (BCS, lateral vs bilateral, pre-operative grading, surgical techniques, removal of implants, concomitance with anterior cruciate ligament (ACL rupture, re-luxation, re-operation, and rehabilitation was obtained from the medical records. The breeds were as follows: Chihuahua (n=23, Pomeranian (n=12, Yorkshire Terrier (n=9, and so on. The study group consisted of 33 males (castrated n=13 and 42 females (spayed n=21. The median age was 53.3±35.9 months (32-146 months; 13 cases were less than 12 months of age (17.3%. The pre-surgical BCSs were as follows: 1 (n=0, 2 (n=20, 3 (n=24, 4 (n=24 and 5 (n=7. The body weight was 4.51±3.48 kg (1.34-23.0 kg; 71 cases (94.7% were less than 10 kg. The MPL grades (each limb were G1 (n=1, G2 (n=18, G3 (n=78, and G4 (n=10; 32 cases were bilateral and 43 cases were unilateral (right n=27; left n=16. The specific surgical procedure (distal femoral osteotomy was 3 stifles in Chihuahuas. Concurrent with ACL rupture was 16/107 stifles (15.0% corrected with the over-the-top method or the extracapsular method in Papillons (5/6, Chihuahuas (5/23, and so on. The occurrences of re-luxation and re-operation were 3 out of 107 stifles (2.8% and 0%, respectively. In this retrospective study, we present a potentially good surgical landmark for block recession of MPL in dogs.

    This case report describes the healing of gingival recessions on mandibular incisors resulting from orthodontic treatment of a deep bite malocclusion at a 30-year follow-up observation. The marked improvement in the severe recessions was a consequence of the elimination of the direct trauma, orthodontic intrusion of the affected teeth, and subsequent creeping attachment over time. No periodontal treatment was performed before or after orthodontic treatment.

    We report on the climatic trends associated with glacier recession in the tropical Andes from the mid-1980s to the mid-2000s. These glaciers comprise 99% of the world's tropical glaciers and occur in Bolivia, Peru, Ecuador, Colombia, and Venezuela. We previously reported on our comprehensive analysis of Landsat imagery of these glaciers, which indicated an overall recession of approximately 30% in glacierized area between c1987 and c2006, or a drop from ~2500 km2 to ~1800 km2 in total glacier area. In the current work, we have examined trends in temperature, cloud cover, and precipitation and compared these trends with those in glacier recession. For temperature and cloud cover, we use the MERRA reanalysis datasets (Modern Era Retrospective-Analysis for Research and Applications) produced by the NASA Goddard's GMAO (Global Modeling and Assimilation Office), which are based on satellite observations. For precipitation, we use the GPCP (Glocal Precipitation Climatology Project) datasets, which are based on both ground and satellite observations. We find that over the glacierized zones, the only significant trends are those in temperature, which show increases of up to 0.5 degree C per decade over some glacierized areas. Trends in cloud cover and precipitation are not generally significant. We discuss these trends in relation to glacier recession trends for each of the major glacierized areas of the tropical Andes.

    2018-01-01

    An extensive literature documents immediate and persistent adverse labor market outcomes for individuals graduating into an economic downturn, but these effects are heterogeneous across sectors, occupations, and skill levels. In particular, the impact of recessions on the labor market outcomes for new physician graduates remains unknown. We leverage a unique dataset on New York physicians to analyze if and how the Great Recession impacted the labor market of physicians who have completed their residency and fellowship training and are seeking their first job. We find that these physicians do not delay labor market entry and their job searches and other employment outcomes are unaffected by the business cycle. The collage of evidence demonstrates that new graduates were largely unfazed by the recent downturn, which sharply contrasts with other highly educated, high remunerating occupations.

  2. Recession in a linear stepper motor based on piezoelectric actuator and electrorheological clampers

    International Nuclear Information System (INIS)

    Li, Cuihong; Meng, Yonggang; Tian, Yu

    2012-01-01

    A linear inchworm-type stepper motor based on piezoelectric actuator and comb shape electrorheological (ER) clampers was developed and tested. A recession phenomenon in the movement of the motor was found and was significantly affected by the driving voltage of the piezoelectric actuator and ER fluids. A dynamic model to analyze the mechanism of the recession was established. The force ratio of the viscoelastic clamping force (applied high electric field) to the viscous damping force (zero field) of ER fluids is the critical factor which determines the recession. The ratio is also affected by the extension or contraction rate of the actuator during movement, which is affected by the charging and discharging processes. With a relatively large distance between the clamper electrodes and a small displacement activated by the extension of the piezoelectric actuator, the instantaneous shear rate might not be sufficiently high, preventing ER fluids from attaining a shear-thickened and high-strength state. The ratio of yield strength to the viscous strength of ER fluids during movement should be as large as possible to reduce the recession displacement. (paper)

    2014-01-01

    Full Text Available Purpose: This study aimed to evaluate the changes in macular thickness following inferior oblique muscle recession surgery. Materials and Methods: Thirty-eight eyes from 21 patients undergoing ocular muscle surgery were included. Patients were grouped into three groups based on the type of surgical intervention: Group I (n = 12, inferior oblique recession surgery alone; Group II (n = 12, inferior oblique plus horizontal muscle surgery; Group III (n = 14, horizontal muscle surgery alone. Each eye was scanned using the optical coherence tomography (OCT device preoperatively and on the first postoperative day to measure macular thickness. Results: Following surgery, a significant increase in foveal thickness occurred in Group I (P < 0.05 and Group II (P < 0.01. In addition, a statistically significant difference was observed between the groups with regard to the increase in foveal thickness (P = 0.016, with significantly lower changes in Group III. Conclusion: Our findings suggested that inferior oblique muscle recession surgery is associated with an increase in macular thickness.

    Full Text Available Does a country with a heavy dependence on a tourism economy have a tendency to succumb to more risk in a recession? With the shift from manufacturing-based economies in the developing world toward service-based industries, including tourism, a reliance on the tourism industry may erode economic stability in tourism-based countries, making them more prone to fall into a recession due to higher risks. In this paper, we wish to emphasise the positive impact of tourism specialisation indices in the international economy on the probability occurrence of a so-called Great Recession. This article uses a multilevel survival analysis and a generalised linear mixed-effect (GLMM structure modelling to investigate the impact of tourism development on the probability of recession frequency (risk in terms of months of duration and severity, by using data collected from 2007 to 2013 from 71 countries around the world, to see if recession frequency is positively correlated with the various indicators of tourism development. Two GLMMs were fitted to this data: logistic regression and count regression with a Poisson distribution. Results for both regressions show considerable evidence that the ratio between the number of overnight stays and the resident population and travel services as a percentage of commercial service exports positively impacts the probability for a country (from our sample to experience a recession event and can make recession worse in terms of severity, measured in months.

  6. The Gendered Politics of a Global Recession: a news media analysis

    Kim Akass

    2012-07-01

    Full Text Available With an eye on the global recession and as recent austerity measures really begin to bite, the UK's leading campaigner for gender equality, The Fawcett Society, has argued that it is women that stand to suffer the most. The latest report from the Office of National Statistics spells out the miserable truth: cuts to local services in England and Wales have resulted in women's jobs accounting for some '66.4% of the total drop in employment in councils'. On the other side of the Atlantic the economic downturn has been widely reported to have turned a differently gendered course and, according to the North American media, has 'taken a disproportionate toll on male employment'. This article will argue that both the North American and British press are witnessing another backlash against feminism much like that described by Susan Faludi in 1992 and further that this style of media reporting is being used to obfuscate more pressing issues such as the impact of austerity measures upon those living on the poverty line – black and working class families.

    School-based programs, such as Playworks, that guide students in organized activities during recess and make improvements to the recess play yard may lead to significant increases in physical activity-especially for girls. This study builds on past research by investigating the impact of Playworks separately for girls and boys. Twenty-nine schools were randomly assigned to receive Playworks for 1 school year or serve as a control group. Postintervention physical activity data were collected via accelerometers and recess observations. Impacts were estimated separately for girls and boys using regression models. Girls in Playworks schools had significantly higher accelerometer intensity counts and spent more time in vigorous physical activity than girls in control schools. No significant differences based on accelerometer data were found for boys. A significant impact was also found on the types of activities in which girls engaged during recess; girls in the treatment group were less likely than those in the control group to be sedentary and more likely to engage in jumping, tag, and playground games. The current findings suggest that Playworks had a significant impact on some measures of girls' physical activity, but no significant impact on measures of boys' physical activity. © 2015, American School Health Association.

Cross-sectional analysis of the Spanish National Health Surveys 2006 and 2011/12 in people 16-24 years old (3701). Regression analyses for pooled cross-sectional data were developed. Employment status was considered as explanatory variable of health (self-rated health, diagnosed morbidity and mental disorders) and lifestyles (overweight, tobacco and alcohol consumption). Male unemployment was associated with poor self-rated health (OR 1.88; CI 95 % 1.00-3.53), mental disorders (OR 2.42; CI 95 % 1.02-5.76) and tobacco consumption (OR 1.62; CI 95 % 1.00-2.62). During the economic recession, young people presented better health results than in 2006. Unemployed who had never worked consumed less tobacco and alcohol than short-term unemployed. Unemployment was associated in young men with poor self-rated health, mental illness and tobacco consumption. Despite the economic recession, young people presented better self-rated health, diagnosed morbidity and mental health in 2012 than in 2006, especially in women.

    Full Text Available Global recession, started in 2008, is still proving an unresolved perfect storm and the financial crisis has affected also the real economy, creating widespread social unrest. Microfinance institutions (MFIs in developing countries seem however less affected by the worldwide turmoil, due to their segmentation and resilience to external shocks. Recession has a big impact on governance mechanisms, altering the equilibriums among different stakeholders and increasing the risk of investment returns; any governance improvement is highly welcome and recommended. No governance, no money for growth or bare survival. In the confused phase we are living in, at the moment there are not evident winners, but the underbanked poorest, unless properly supported, once again risk being the ultimate losers.

    The objective is to evaluate the prevalence and morphology of recesses along the posterior margin of the infrapatellar fat pad on routine MR imaging of the knee. MR images of 213 knees in 204 consecutive individuals were evaluated with regard to the prevalence and morphology of recesses (a ''suprahoffatic'' recess close to the inferior border of the patella and the previously described ''infrahoffatic'' recess anterior to the inferior portion of the infrapatellar plica). The recesses were analyzed with regard to synovial effusion and the condition of the anterior cruciate ligament (ACL). Anatomic dissection was made in 29 knees in 16 cadavers to verify the presence of the suprahoffatic recess. The infrahoffatic recess was present in 45% of the knees and mostly linear in shape (44%). The suprahoffatic recess was detected in 71% of the knees (45% in cadavers). Very weak to moderate positive correlation was found between the synovial effusion or the condition of the ACL and the presence and dimensions of the recesses. An awareness of the recesses in the infrapatellar fat pad is important in order to distinguish between pathology and anatomic variants on routine MR imaging of the knee. (orig.)

    2016-03-01

    In the present study, we investigated associations of macro-economic conditions - the Great Recession - with cellular epigenetic aging, allostatic load, and self-reported health, in a group that experiences significant health disparities, African Americans. A sample of 330 African American adolescents in Georgia was followed from pre-recession (2007, M age=16.6) to post-recession (2010, M age=19.3). Economic data were collected in both 2007 and 2010. Three groups were formed to represent economic trajectories across the period of the Great Recession (stable low economic hardship, downward mobility, and stable high economic hardship). At age 19, measures of cellular epigenetic aging (derived from leukocyte DNA methylation profiles, reflecting the disparity between a person's biological and chronological age), allostatic load (composite of blood pressure, C reactive protein, cortisol, epinephrine, norepinephrine, and body mass index), and adolescent self-report of health were obtained. Linear trend analyses documented significant differences across all outcomes. The more time adolescents spent under economic hardship, the higher their epigenetic aging [estimate=1.421, SE=0.466, p=.002] and allostatic load [estimate=1.151, SE=0.375, p=.002] scores, and the worse their self-report of health [estimate=4.957, SE=1.800, p=.006]. Specific group comparisons revealed that adolescents in the downward mobility group had higher levels of allostatic load than adolescents in the stable low hardship group [p<.05]. Overall, these findings suggest that the health profiles of African American youth may in part be shaped by environmental macro-economic societal conditions, and that effects on biological markers can be detected relatively early in life.

  14. Working Stiff(s on Reality Television during the Great Recession

    Directory of Open Access Journals (Sweden)

    Sean Brayton

    2012-10-01

    Full Text Available This essay traces some of the narratives and cultural politics of work on reality television after the economic crash of 2008. Specifically, it discusses the emergence of paid labor shows like Ax Men, Black Gold and Coal and a resurgent interest in working bodies at a time when the working class in the US seems all but consigned to the dustbin of history. As an implicit response to the crisis of masculinity during the Great Recession these programs present an imagined revival of manliness through the valorization of muscle work, which can be read in dialectical ways that pivot around the white male body in peril. In Ax Men, Black Gold and Coal, we find not only the return of labor but, moreover, the re-embodiment of value as loggers, roughnecks and miners risk both life and limb to reach company quotas. Paid labor shows, in other words, present a complicated popular pedagogy of late capitalism and the body, one that relies on anachronistic narratives of white masculinity in the workplace to provide an acute critique of expendability of the body and the hardships of physical labor.

    The dry recessed-gate GaN metal-oxide-semiconductor field-effect transistors (MOSFETs) on AlGaN/GaN heterostructure using boron trichloride (BCl 3 ) as etching gas were fabricated and characterized. Etching with different etching power was conducted. Devices with silicon tetrachloride (SiCl 4 ) etching gas were also prepared for comparison. Field-effect mobility and interface state density were extracted from current-voltage (I-V) characteristics. GaN MOSFETs on AlGaN/GaN heterostructure with BCl 3 based dry recess achieved a high maximum electron mobility of 141.5 cm 2 V −1 s −1 and a low interface state density.

    Full Text Available Abstract Background Wolfram Syndrome (WS is an autosomal recessive disorder characterised by non-autoimmune diabetes mellitus, optic atrophy, cranial diabetes insipidus and sensorineural deafness. Some reports have described hypogonadism in male WS patients. The aim of our study was to find out whether Wfs1 deficient (Wfs1KO male mice have reduced fertility and, if so, to examine possible causes. Methods Wfs1KO mice were generated by homologous recombination. Both Wfs1KO and wild type (wt male mice were mated with wt female mice. The number of litters and the number of pups were counted and pregnancy rates calculated. The motility and morphology of the sperm and the histology of testes were analysed. Serum testosterone and FSH concentrations were also measured. Results The pregnancy rate in wt females mated with Wfs1KO males was significantly lower than in the control group (15% vs. 32%; p Conclusion The impaired fertility of Wfs1KO male mice is most likely due to changes in sperm morphology and reduced number of spermatogenic cells. The exact mechanism through which the Wfs1 gene influences sperm morphology needs to be clarified in further studies.

    2015-12-01

    Although the consequences of the Great Recession are extensively discussed in previous research, three critical issue need to be addressed in order to develop a full portrait of the economic experiences of children during this period. First, given the changing immigrant composition of the US child population, new studies are needed for examining the implications of immigrant status for exposure to child poverty during the recession. Second, it is important to understand how traditional patterns of racial inequality among were transformed during the years of the recession. Finally, it is not clear whether recession-related changes in socioeconomic inequalities continued to have implications for child well-being in the post-recession period. Results from this analysis indicate that the adverse effects of the recession were most intense in states with significant changes in their populations of Black and Latino immigrant children. The results further show that declines in parental work opportunities were more consequential for poverty among Whites and Asians. The analysis also finds differential implications of family contexts for child poverty among Black immigrant and natives during the recession. Finally, the results indicate that increases in racial child poverty disparities during the recession did not disappear in the years following the downturn.

  1. Real-Time Inhibitor Recession Measurements in the Space Shuttle Reusable Solid Rocket Motors

    Real-time char line recession measurements were made on propellant inhibitors of the Space Shuttle Reusable Solid Rocket Motor (RSRM). The RSRM FSM-8 static test motor propellant inhibitors (composed of a rubber insulation material) were successfully instrumented with eroding potentiometers and thermocouples. The data was used to establish inhibitor recession versus time relationships. Normally, pre-fire and post-fire insulation thickness measurements establish the thermal performance of an ablating insulation material. However, post-fire inhibitor decomposition and recession measurements are complicated by the fact that most of the inhibitor is back during motor operation. It is therefore a difficult task to evaluate the thermal protection offered by the inhibitor material. Real-time measurements would help this task. The instrumentation program for this static test motor marks the first time that real-time inhibitors. This report presents that data for the center and aft field joint forward facing inhibitors. The data was primarily used to measure char line recession of the forward face of the inhibitors which provides inhibitor thickness reduction versus time data. The data was also used to estimate the inhibitor height versus time relationship during motor operation.

    The objectives of this study were to record the prevalence and degree of absence of the maxillary midline interdental papilla and the proportion of patients displaying the maxillary midline papilla during maximum smile among a Caucasian population. Papillary recession was found in 46.4% of study participants (n = 211), while the prevalence of visible recession among maxillary midline papilla during maximum smile was 38.4%, which was statistically significantly less than that of patients diagnosed intraorally with loss of papillary height (P line as well as age and visible papillary recession were identified for individuals over 65 years of age. The high prevalence of midline papillary recession in the maxilla found in this population suggests that loss of papillary height constitutes a substantial clinical challenge.

  3. Operation and scalability of dopant-segregated Schottky barrier MOSFETs with recessed channels

    2013-01-01

    Recessed channels were used in scaled dopant-segregated Schottky barrier MOSFETs (DS-SBMOS) to control the severe short-channel effect. The physical operation and device scalability of the DS-SBMOS resulting from the presence of recessed channels and associated gate-corners are elucidated. The coupling of Schottky and gate-corner barriers has a key function in determining the on–off switching and drain current. The gate-corner barriers divide the channel into three regions for protection from the drain penetration field. To prevent resistive degradations in the drive current, an alternative asymmetric recessed channel (ARC) without a source-side gate-corner is proposed to simultaneously optimize both the short-channel effect and drive current in the scaled DS-SBMOS. By employing the proposed ARC architecture, the DS-SBMOS devices can be successfully scaled down, making them promising candidates for next-generation CMOS devices. (paper)

    Employment status and economic recession have been associated with negative effects on self-rated health, and this effect differs by gender. We analysed the effects of the Spanish economic recession in terms of self-rated health, its differential effect among genders and its influence on gender gap. Repeated cross-sectional study using Spanish health surveys (2001-2014). Logistic regression models were conducted to explore the association between self-rated health and employment status and its evolution over time and gender. To test the impact of the economic recession, pooled data regression models were conducted. In this study, we considered 104,577 subjects. During the last 15 years, women have entered the labour market, leading to wide changes in the Spanish traditional family roles. Instead of an increasing proportion of women workers, gender employment differences persist. Therefore, in 2014, the prevalence of workers was 55.77% in men, whereas in women, it was 44.01%. Self-rated health trends during the economic recession differ by gender, with women improving slightly their self-rated health from a low self-rated health prevalence of 38.76% in 2001 to 33.78% in 2014. On the contrary, men seem more vulnerable to employment circumstances, which have led to substantial reduction in the gender gap. Although a gender gap persists, the change in socio-economic roles seems to increase women's self-rated health, reducing this gap. It is important to promote women's labour market inclusion, even in economic recession periods. Copyright © 2017 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

    Real-time internal motor insulation char line recession measurements have been evaluated for two full-scale static tests of the Space Shuttle Reusable Solid Rocket Motor (RSRM). These char line recession measurements were recorded on the forward facing propellant grain inhibitors to better understand the thermal performance of these inhibitors. The RSRM propellant grain inhibitors are designed to erode away during motor operation, thus making it difficult to use post-fire observations to determine inhibitor thermal performance. Therefore, this new internal motor instrumentation is invaluable in establishing an accurate understanding of inhibitor recession versus motor operation time. The data for the first test was presented at the 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit (AIAA 2001-3280) in July 2001. Since that time, a second full scale static test has delivered additional real-time data on inhibitor thermal performance. The evaluation of this data is presented in this paper. The second static test, in contrast to the first test, used a slightly different arrangement of instrumentation in the inhibitors. This instrumentation has yielded a better understanding of the inhibitor time dependent inboard tip recession. Graphs of inhibitor recession profiles with time are presented. Inhibitor thermal ablation models have been created from theoretical principals. The model predictions compare favorably with data from both tests. This verified modeling effort is important to support new inhibitor designs for a five segment Space Shuttle solid rocket motor. The internal instrumentation project on RSRM static tests is providing unique opportunities for other real-time internal motor measurements that could not otherwise be directly quantified.

    2010-04-01

    This paper examines recent trends in health insurance cost and coverage for the near-elderly population (aged 55 to 64), with particular attention directed toward the implications of the 2007 recession. We examine coverage by demographic and socioeconomic characteristics from the Current Population Survey and the Medical Expenditure Panel Survey. We also estimate the effects of projected increases in the unemployment rate for employer-sponsored insurance coverage of the near elderly in 2009 and 2010. Erosion in coverage is likely to be exacerbated in the short run by the 2007 recession, given rapidly rising unemployment among this age cohort, and in the long-run, given the inability of the labor market to support increased labor market participation of older Americans in jobs that would have traditionally provided health insurance coverage.

    This paper is a re-examination of the global financial crisis that began in and was accompanied by the most severe recession since the Great Depression. It builds on our earlier paper (Dore and Singh, 2009) and expands its scope. It is divided into parts. The first part deals with the ideological backdrop in which this crisis occurred, namely the belief in the rationality and stability of all markets including the capital markets, called the 'efficient market hypothesis.' The second part is a survey of the role of income distribution and its relations to aggregate spending and the growing role played by credit in the circular flow of income. The third part examines some features of the business cycle expansion phase of to . The fourth part is a brief report on a nonlinear Vector Error Correction model spanning the period to and how this expansion came to an end. The fifth part is a brief comparison of the Great Recession with the Great Depression. Finally in the sixth part, the international impact of the Great Recession is considered briefly, followed by some conclusions.

    The infantile variant of Bartter syndrome (IBS) is usually associated with maternal polyhydramnios, premature birth, postnatal polyuria and hypokalemic hypochloremic metabolic alkalosis and a typical appearance. IBS is thought to be an autosomal recessive trait. Several congenital tubular defects are associated with sensorineural deafness (SND). However, an association between the IBS and SND has not been reported so far. Here we describe 5 children of an extended consanguineous Bedouin family with IBS and SND. In 3 of the cases, the typical electrolyte imbalance and facial appearance were detected neonatally. SND was detected as early as age 1 month, suggesting either coincidental homozygotization of 2 recessive genes or a pleiotropic effect of one autosomal recessive gene. This association suggests that evaluation of SND is warranted in every case of IBS. 35 refs., 2 figs., 2 tabs.

    Full Text Available Landsat imagery was applied to elucidate glacier fluctuations of land- and marine-terminating outlet glaciers from the Greenland Ice Sheet (GrIS and local land-terminating glaciers and ice caps (GIC peripheral to the GrIS in the Ammassalik region, Southeast Greenland, during the period 1972–2011. Data from 21 marine-terminating glaciers (including the glaciers Helheim, Midgaard, and Fenris, the GrIS land-terminating margin, and 35 GIC were examined and compared to observed atmospheric air temperatures, precipitation, and reconstructed ocean water temperatures (at 400 m depth in the Irminger Sea. Here, we document that net glacier recession has occurred since 1972 in the Ammassalik region for all glacier types and sizes, except for three GIC. The land-terminating GrIS and GIC reflect lower marginal and areal changes than the marine-terminating outlet glaciers. The mean annual land-terminating GrIS and GIC margin recessions were about three to five times lower than the GrIS marine-terminating recession. The marine-terminating outlet glaciers had an average net frontal retreat for 1999–2011 of 0.098 km yr−1, which was significantly higher than in previous sub-periods 1972–1986 and 1986–1999. For the marine-terminating GrIS, the annual areal recession rate has been decreasing since 1972, while increasing for the land-terminating GrIS since 1986. On average for all the observed GIC, a mean net frontal retreat for 1986–2011 of 0.010 ± 0.006 km yr−1 and a mean areal recession of around 1% per year occurred; overall for all observed GIC, a mean recession rate of 27 ± 24% occurred based on the 1986 GIC area. Since 1986, five GIC melted away in the Ammassalik area.

    Osteopetrosis is a hereditary form of sclerosing bone dysplasia with various radiological and clinical presentations. The autosomal recessive type, also known as malignant osteopetrosis, is the most severe type, with the early onset of manifestations. A 5-month-old infant was admitted to our hospital with recurrent respiratory tract infections. Chest X-ray and skeletal survey revealed the classic findings of osteopetrosis, including diffuse osteosclerosis and bone within a bone appearance. At follow-up, the patient presented with, thickened calvarium, multiple prominent encephaloceles, and dural calcifications leading to the intracranial clinical manifestations with bilateral hearing and sight loss. Autosomal recessive osteopetrosis is one of the causes of encephaloceles and this finding may become dramatic if untreated. (orig.)

    2012-01-01

    This study investigated how the current economic recession (since December 2007) has affected dog and cat relinquishment, adoption, and euthanasia at the Anti-Cruelty Society animal shelter in Chicago, Illinois. The study compared temporal patterns of the investigated statistics before (2000-2007) the start of the current recession with the patterns after the start of the recession (2008-2010). The results showed that once the guardianship (ownership) of a nonhuman animal had been established, the recession did not greatly affect the owner's decision on relinquishment-except for the relinquishment of senior dogs, which may be associated with increased costs of care. However, an unfavorable economic environment may have reduced adoption of animals. The consequences of a decline in adoptions might be reflected in an increase in the proportion or number of sheltered animals euthanized. This study demonstrated how monitoring changes in temporal patterns in these shelter statistics can help guide animal shelters to better prepare for the current recession.

    Much evidence has shown that postzygotic reproductive isolation (hybrid inviability or sterility) evolves by the accumulation of interlocus incompatibilities between diverging populations. Although in theory only a single pair of incompatible loci is needed to isolate species, empirical work in Drosophila has revealed that hybrid fertility problems often are highly polygenic and complex. In this article we investigate the genetic basis of hybrid sterility between two closely related species of monkeyflower, Mimulus guttatus and M. nasutus. In striking contrast to Drosophila systems, we demonstrate that nearly complete hybrid male sterility in Mimulus results from a simple genetic incompatibility between a single pair of heterospecific loci. We have genetically mapped this sterility effect: the M. guttatus allele at the hybrid male sterility 1 (hms1) locus acts dominantly in combination with recessive M. nasutus alleles at the hybrid male sterility 2 (hms2) locus to cause nearly complete hybrid male sterility. In a preliminary screen to find additional small-effect male sterility factors, we identified one additional locus that also contributes to some of the variation in hybrid male fertility. Interestingly, hms1 and hms2 also cause a significant reduction in hybrid female fertility, suggesting that sex-specific hybrid defects might share a common genetic basis. This possibility is supported by our discovery that recombination is reduced dramatically in a cross involving a parent with the hms1-hms2 incompatibility.

    Primary care access (PCA) for the homeless can prove challenging, especially during periods of economic distress. In the United States, the most recent recession may have presented additional barriers to accessing care. Limited safety-net resources traditionally used by the homeless may have also been used by the non-homeless, resulting in delays in seeking treatment for the homeless. Using hospitalizations for ambulatory care sensitivity (ACS) conditions as a proxy measure for PCA, this study investigated the recession's impact on PCA for the homeless and non-homeless in four states. The State Inpatient Databases were used to identify ACS admissions. Findings from this study indicate the recession was a barrier to PCA for homeless people who were uninsured. Ensuring that economically-disadvantaged populations have the ability to obtain insurance coverage is crucial to facilitating PCA. With targeted outreach efforts, the Affordable Care Act provides an opportunity for expanding coverage to the homeless.

    Gallium oxide (Ga2O3) metal-oxide-semiconductor field-effect transistors (MOSFETs) were fabricated with gate recess depths of 110 nm and 220 nm, respectively. The gate recess was formed by dry plasma etching with Cr metal as the mask. The fabricated devices with a 25-nm HfO2 gate dielectric both showed a low off-state drain current of about 1.8 × 10-10 A/mm. The effects of recess depth on the electronic characteristics of Ga2O3 MOSFETs were investigated. Upon increasing the recess depth from 110 nm to 220 nm, the saturated drain current decreased from 20.7 mA/mm to 2.6 mA/mm, while the threshold voltage moved increased to +3 V. Moreover, the breakdown voltage increased from 122 V to 190 V. This is mainly because the inverted-trapezoidal gate played the role of a gate-field plate, which suppressed the peak electric field close to the gate.

    Full Text Available The width of the attached gingiva is defined as a distance between the depth of the gingival sulcus or gingival/periodontal pocket to the mucogingival junction. Authors suggest that a minimal amount of attached gingiva is necessary to ensure the gingival health. When the buccal bone plate and gingival tissues are thin and the position of the tooth is too vestibular gingival margin often displaces apically, and gingival recession develops. In the presence of gingival recession and reduced vestibular depth oral hygiene procedures are embarrassed.The definition of class III gingival recession is marginal lack of tissue extended to/or beyond the mucogingival junction with bone and soft tissue loss interdentally or malpositioning of the tooth.Prognosis for class III and IV gingival recession is that only partial coverage can be expected after root coverage procedures - FGG (free gingival graft or connective tissue graft (CTG. Adjunctive surgical techniques would be helpful to achieve better aesthetic outcomes.

    Full Text Available In the period 2008–2010, the labour market of the European Union was significantly affected by the economic recession, which impacted economic development in all regions of the Czech Republic including the South Moravian Region. Impacts of the economic recession in the labour market were primarily reflected on decline of vacant work places, an increase in job seekers, and thus an increase in the unemployment rate, as well as an increase in long-term unemployment,etc. Enterprises in the region are responding to this situation in different ways, but all have to flexibly adapt – increase or decrease – the number of employees and production as movements in the labour market have been very significant for the past four years. In 2011 and 2012, the economic recession was not discussed anymore. However, has it already finished? The analysis of movements in the labour market, especially comparison of plans and reality in enterprises during and after economic recession is the aim of the paper.

    Full Text Available This paper examines the association between the Great Recession and real assets among families with young children. Real assets such as homes and cars are key indicators of economic well-being that may be especially valuable to low-income families. Using longitudinal data from the Fragile Families and Child Wellbeing Study (N = 4,898, we investigate the association between the city unemployment rate and home and car ownership and how the relationship varies by family structure (married, cohabiting, and single parents and by race/ethnicity (White, Black, and Hispanic mothers. Using mother fixed-effects models, we find that a one percentage point increase in the unemployment rate is associated with a -0.5 percentage point decline in the probability of home ownership and a -0.7 percentage point decline in the probability of car ownership. We also find that the recession was associated with lower levels of home ownership for cohabiting families and for Hispanic families, as well as lower car ownership among single mothers and among Black mothers, whereas no change was observed among married families or White households. Considering that homes and cars are the most important assets among middle and low-income households in the U.S., these results suggest that the rise in the unemployment rate during the Great Recession may have increased household asset inequality across family structures and race/ethnicities, limiting economic mobility, and exacerbating the cycle of poverty.

    Full Text Available This paper explores the findings regarding the impact of recession that began in 2008 in Slovenia to the chosen parameters of quality of regional centres, which are reflected in their attractiveness. We wanted to test the assumption of the impact of recession to the attractiveness of regional centres to both internal migration and commuting flows. To this end, an adjusted gravity spatial interaction model was developed by evaluating regression coefficients. We analysedthe impacts of population size, distance, employment, gross personal income, municipality revenue per capita, average price per square metre of apartments and houses, and age structure in the municipality pertaining to the decision to potentially migrate or commute related to the migration and choice of workplace in the regional centre. The impact of the recession was analysed by comparing the estimations of regression coefficients before the recession (2007 and duringthe recession (2011. It is shown that during the recession, internal migrations to regional centres increased considerably, while commuting to regional centres did not change significantly. We alsoshowed that during the recession, the impact of the distance to the decision to migrate to regional centres slightly increased, while the impact of the distance to the decision to commute did not changesignificantly. Notably, during the crisis the impact of municipality revenue per capita in the regional centre to the analysed flows changed the most: during the recession, the decision to migrate and/orcommute to 'more prosperous' regional centres is made more easily.In the future, it is to be expected that local self-governments will make more effort to consider how to attract taxpayers to their local community and hence enrich the community, while the analysis of theseparameters will become more significant for the individual levels of the local self-government. Gravity models, such as the one used here, include different

  10. Molecular Mapping of D1, D2 and ms5 Revealed Linkage between the Cotyledon Color Locus D2 and the Male-Sterile Locus ms5 in Soybean

    Full Text Available In soybean, genic male sterility can be utilized as a tool to develop hybrid seed. Several male-sterile, female-fertile mutants have been identified in soybean. The male-sterile, female-fertile ms5 mutant was selected after fast neutron irradiation. Male-sterility due to ms5 was associated with the “stay-green” cotyledon color mutation. The cotyledon color trait in soybean is controlled by two loci, D1 and D2. Association between cotyledon color and male-sterility can be instrumental in early phenotypic selection of sterility for hybrid seed production. The use of such selection methods saves time, money, and space, as fewer seeds need to be planted and screened for sterility. The objectives of this study were to compare anther development between male-fertile and male-sterile plants, to investigate the possible linkages among the Ms5, D1 and D2 loci, and to determine if any of the d1 or d2 mutations can be applied in hybrid seed production. The cytological analysis during anther development displayed optically clear, disintegrating microspores and enlarged, engorged pollen in the male-sterile, female-fertile ms5ms5 plants, a common characteristic of male-sterile mutants. The D1 locus was mapped to molecular linkage group (MLG D1a and was flanked by Satt408 and BARCSOYSSR_01_1622. The ms5 and D2 loci were mapped to MLG B1 with a genetic distance ~12.8 cM between them. These results suggest that use of the d2 mutant in the selection of male-sterile line may attenuate the cost hybrid seed production in soybean.

    Gingival recession is a common occurrence and patients often report to dental clinic with associated problems such as root surface hypersensitivity, esthetic concerns, cervical root abrasions, and root caries that make it a concern for patients. Based upon the fact that gingival recession is an enigma for clinicians because of multitude of etiological factors and plethora of treatment modalities present for its treatment, a survey was conducted to assess knowledge as well as opinion about most common etiology, classification, and preferred treatment of gingival recession and to evaluate the interest and satisfaction of dentists in practicing periodontics. Study design consisted of a cross-sectional online survey, conducted among dentists practicing in state of Punjab, India, in the month of April 2011. A structured online questionnaire consisting of 17 questions evaluating the interest of dentists in periodontics based on knowledge about gingival recession (most of them giving the possibility of multiple choices of answers) was sent to about 300 dentists. Pearson Chi-Square and Mann-Whitney U tests were used for statistical analysis of data collected. P ≤ 0.05 was considered as statistically significant and P ≤ 0.01 considered as highly significant. A greater proportion of periodontists had better knowledge about etiology (P = 0.07), classification (P = 0.000), and treatment of gingival recession (P = 0.000). A greater number of periodontists opted for the surgical modalities to correct the defects produced by gingival recession as compared to non-periodontists and had better interest (P = 0.000) and satisfaction (P = 0.000) in practicing periodontics. The results elucidated that periodontists had better interest and satisfaction in practicing periodontics, and were more inclined towards surgical correction of gingival recession as compared to non-periodontists.

  16. Site-Specific Bluff Recession Rates Measured on the Alaskan Beaufort Sea Coast

    OverviewThe effects of climate change are being studied globally with coastal erosion in Arctic regions of particular concern. In support of Hilcorp Alaska's Northstar Development, short- and long-term bluff recession rates have been documented at a pipeline shore crossing located in Gwydyr Bay on the Alaskan Beaufort Sea coast. These data are presented, along with the predominant forcing mechanisms, and compared to local and regional recession rates recently published by the U.S. Geological Survey (USGS). Arctic Bluff RecessionCoastal retreat along the northern coast of Alaska occurs at two different rates: infrequent, but rapid erosion induced by strong westerly storms, and seasonal retreat related to thawing and sediment removal under more moderate wave conditions. Variability in the rate of bluff retreat is related to a number of factors, including bluff composition (ice content and sediment type), existence of a fronting beach, and wave exposure. Measured Bluff Recession at the Northstar Pipeline Shore CrossingThe location of the Northstar Development pipeline shore crossing was chosen based on analysis of historical aerial photos acquired between 1949 and 1996. Over this 47-year period, the average annualized rate of bluff retreat in the study area ranged from 1.6 to 3.0 ft/yr. Beginning in 1996, ground-based shoreline monitoring surveys have been conducted along the bluff and ten shore-perpendicular transects at the site. The rates of bluff retreat derived from the survey data have been modest, ranging from no change to 5.8 ft/yr. The monitoring surveys indicate that waves and currents erode the bluffs by direct impact only during infrequent, but strong westerly storms that promote a short-term rise in sea level (storm surge). The more prevalent easterly storms can cause set-down, or reduction in the sea level which limits direct wave impact on the bluff, thereby decreasing the potential for wave induced erosion.

    The aim of this study was to evaluate the dose effect and the resulting binocular single vision for inferior oblique muscle recession in patients with Grave's orbitopathy. The evaluation covered all patients (n = 13) between 2010-2013 treated with recession of the inferior oblique muscle for vertical deviation caused by inferior fibrosis of the contralateral eye. The inclusion criterion was a small vertical squint angle with excyclotorsion. The corrected vertical squint angle was 3.75° [7 pdpt] (median, min 1.5° [3 pdpt], max 8° [16 pdpt]) in primary position and 5.5° in adduction [11pdpt] (median, min 3°[6 pdpt], max 9°[18pdpt]). Excyclotorsion was 4° [8 pdpt] (median, min 1° [2 pdpt], max 9° [18 pdpt]). Elevation was only slightly impaired and the side difference was 5° (median). The recession distance was preoperatively determined: 0.5° squint angle reduction per mm recession distance (calculation from patients who received surgery before 2010). Inferior oblique recession generated a good field of binocular single vision (BSV) for all patients. All patients reached BSV in the central area (20°) and within 30° of downgaze. Sixty nine percent of the patients were completely diplopia free in downgaze. Diplopia persisted in more than half of the patients in up gaze outside 15°. Squint reduction was 0.5° [1 pdpt] [0.45-0.67]/per mm recession distance in primary position and 0.65° [1.3 pdpt] [0.55-0.76]/per mm for the vertical deviation in adduction. Excyclotorsion was reduced to ≤ 2° in 77 % of the patients. Inferior oblique muscle recession can be very successfully performed on the contralateral eye in patients with mild inferior rectus muscle fibrosis. Surgery at the contralateral yoke muscle prevents the risk of overeffect with resulting diplopia in downgaze, which could occur if small distance recession had been performed at the inferior rectus muscle. An overeffect in relation to inferior oblique recession will only

    Across the globe, economic fluctuations have taken their toll on both organizations and employees, particularly during sustained recessions. Surprisingly, little research, however, has directly investigated the effects of recessions on employees. As such, the goal of the current study was to investigate the effects of specific recession-related stressors on employee outcomes (strain and satisfaction). We investigated an archival data set of 7666 individuals collected as part of the Workplace Employment Relations Study for relations among recession-related stressors with strain and job satisfaction variables. We found that recession-related stressors were significantly related to both strain and satisfaction. More specifically, certain recession-related stressors (e.g. increased workload and reorganization of work) were more strongly related to strain and satisfaction than others. These results imply the need for greater attention to stress management strategies aimed at helping both employees and their organizations cope with the human costs of economic recessions.

    Male sterile plants appeared in the population of N cytoplasm sugar beet strains, H-19 and H-2002, when their dry seeds were exposed to 50 kR gamma-ray, and the male sterility was maintained up to the M/sub 4/ generation through the mother plants. Cytoplasmic inheritance was confirmed by the reciprocal crossings between plants with normal phenotype from gamma-strains (progeneis of the male mutants which transmitted male sterility through the mother plants) and H-19 or H-1001. The crossing experiments suggested that various kinds of cytoplasm were induced by gamma-ray irradiation, and that different nuclear genes were responsible for the respective cytoplasms. A specific relationship between the pollen restoring genes and the sterile cytoplasms was established, and was named ''one set of pollen restoring genes for one cytoplasm''. It is probable that the cytoplasmic mutation occurred in normal cytoplasm strains and the specific combination between the altered cytoplasm and the recessive nuclear gene produced male sterility. Ethyl methane sulphonate, ethidium bromide, acriflavine and streptomycin were also effective in inducing cytoplasmic mutation in sugar beets.

    Depending on the size of the subcarinal and retrobronchial recess the medial wall of the right and perhaps the left main bronchus can be recognized. The medial extension of the recess is very variable. On lateral films with slight anterior rotation of the right shoulder, the posterior wall of the right main bronchus can be shown in 97% of patients. Awareness of this recess and its boundaries is essential for diagnosis of subcarinal and tracheobronchial node enlargement. The following 4 signs will assist in diagnosis: 1. The dorsal margin of enlarged nodes may be recognized posterior and inferior to the carina. 2. The posterior wall of the right main bronchus can no longer be seen. 3. The medial wall of the right main bronchus can no longer be seen. 4. Clearer demonstration of the right main bronchus or bronchus intermedius occurs, due to an 'air bronchogram' effect. Due to the application of these 4 signs, enlargements of the subcarinal or tracheobronchial nodes can be recognized, at a stage where the tracheal bifurcation is not yet splayed, and when the nodes have not yet caused bronchostenosis.

    2010-01-01

    The Latvian recession, which is now more than two years old, has seen a world-historical drop in GDP of more than 25 percent. The IMF projects another 4 percent drop this year, and predicts that the total loss of output from peak to bottom will reach 30 percent. This would make Latvia’s loss more than that of the U.S. Great Depression downturn of 1929-1933. This paper argues that the depth of the recession and the difficulty of recovery are attributable in large part to the decision to mainta...

    Full Text Available Background/Aim. Gingival recession progression in clinical practice as an ethiological factor of periodontal diseases, and symptoms of the disease have caused the development of various surgical procedures and techniques of the reconstruction of periodontal defects. The aim of this study was to verify efficacy of surgical procedures that include connective tissue autotransplants with periosteum and guided tissue regeneration for the treatment of gingival recession. Methods. The study included 20 teet with gingival recession, Müller class II and III. Ten teeth with gingival recession were treated with resorptive membrane and coronary guided surgical flap (GTR group. On the contralateral side 10 teeth with gingival recession were treated with connective tissue autotransplants with periosteum in combination with coronary guided surgical flap (TVT group. We measured the degree of epithelial attachment (DEA, width of subgingival curettage (WGC and vertical deepness of recession (VDR. For statistical significance we used Student's ttest. Results. The study revealed statistical significance in reducing VDR by both used treatments. Root deepness in GTR and TVT group was 63.5%, and 90%, respectively. With both surgical techniques we achieved coronary dislocation of the epithelial attachment, larger zone of gingival curettage, and better oral hygiene. Conclusion. Current surgical techniques are effective in the regeneration of deep periodontal spaces and the treatment of gingival recession. Significantly better results were achieved with the used coronary guided surgical flap than with guided tissue regeneration.

  6. Chromosome Synapsis and Recombination in Male Hybrids between Two Chromosome Races of the Common Shrew (Sorex araneus L., Soricidae, Eulipotyphla

    Full Text Available Hybrid zones between chromosome races of the common shrew (Sorex araneus provide exceptional models to study the potential role of chromosome rearrangements in the initial steps of speciation. The Novosibirsk and Tomsk races differ by a series of Robertsonian fusions with monobrachial homology. They form a narrow hybrid zone and generate hybrids with both simple (chain of three chromosomes and complex (chain of eight or nine synaptic configurations. Using immunolocalisation of the meiotic proteins, we examined chromosome pairing and recombination in males from the hybrid zone. Homozygotes and simple heterozygotes for Robertsonian fusions showed a low frequency of synaptic aberrations (<10%. The carriers of complex synaptic configurations showed multiple pairing abnormalities, which might lead to reduced fertility. The recombination frequency in the proximal regions of most chromosomes of all karyotypes was much lower than in the other regions. The strong suppression of recombination in the pericentromeric regions and co-segregation of race specific chromosomes involved in the long chains would be expected to lead to linkage disequilibrium between genes located there. Genic differentiation, together with the high frequency of pairing aberrations in male carriers of the long chains, might contribute to maintenance of the narrow hybrid zone.

  7. Influence of Genetic Drift of Restoring Gene (Rf on Seed Purity of Yuetai A, a Honglian-Type Cytoplasmic Male Sterile Line in Hybrid Rice

    Full Text Available The seed samples of Yuetai A, a Honglian (HL type cytoplasmic male sterile (CMS line in hybrid rice were investigated to assess the seed purity and to analyze the cause of off-type plants by imitating the biological contaminant to Yuetai A in Nanjing, Jiangsu Province and Lingshui, Hainan Province during 2004–2006. The seed impurity of Yuetai A mainly resulted from the genetic drift of restoring fertility gene (Rf after biological contamination but not from its sterility unstability. All of the ten maintainer lines, five restorer lines and three thermo-sensitive genic male sterile lines used in the study could pollinate Yuetai A and Yuetai B to produce F1 plants, directly or indirectly resulting in Rf-gene drifting into Yuetai A and generating ‘iso-cytoplasm restoring-generations’. Furthermore, high outcrossing rate and similar heading date of Yuetai A with many varieties used in rice production might easily result in the biological contamination. After removing all plants with Rf-gene mixed in Yuetai A and preventing Rf-gene drifting into Yuetai A, the seed purity of Yuetai A and Yuetai B had been raised to 100%.

    PurposeTo characterize the molecular genetics of autosomal recessive Noonan syndrome.MethodsFamilies underwent phenotyping for features of Noonan syndrome in children and their parents. Two multiplex families underwent linkage analysis. Exome, genome, or multigene panel sequencing was used to identify variants. The molecular consequences of observed splice variants were evaluated by reverse-transcription polymerase chain reaction.ResultsTwelve families with a total of 23 affected children with features of Noonan syndrome were evaluated. The phenotypic range included mildly affected patients, but it was lethal in some, with cardiac disease and leukemia. All of the parents were unaffected. Linkage analysis using a recessive model supported a candidate region in chromosome 22q11, which includes LZTR1, previously shown to harbor mutations in patients with Noonan syndrome inherited in a dominant pattern. Sequencing analyses of 21 live-born patients and a stillbirth identified biallelic pathogenic variants in LZTR1, including putative loss-of-function, missense, and canonical and noncanonical splicing variants in the affected children, with heterozygous, clinically unaffected parents and heterozygous or normal genotypes in unaffected siblings.ConclusionThese clinical and genetic data confirm the existence of a form of Noonan syndrome that is inherited in an autosomal recessive pattern and identify biallelic mutations in LZTR1.Genet Med advance online publication, 22 February 2018; doi:10.1038/gim.2017.249.

    As populations decline to levels where reproduction among close genetic relatives becomes more probable, subsequent increases in homozygous recessive deleterious expression and/or loss of heterozygote advantage can lead to inbreeding depression. Here, we measure how inbreeding across replicate lines of the flour beetle Tribolium castaneum impacts on male reproductive fitness in the absence or presence of male–male competition. Effects on male evolution from mating pattern were removed by enforcing monogamous mating throughout. After inbreeding across eight generations, we found that male fertility in the absence of competition was unaffected. However, we found significant inbreeding depression of sperm competitiveness: non-inbred males won 57 per cent of fertilizations in competition, while inbred equivalents only sired 42 per cent. We also found that the P2 ‘offence’ role in sperm competition was significantly more depressed under inbreeding than sperm ‘defence’ (P1). Mating behaviour did not explain these differences, and there was no difference in the viability of offspring sired by inbred or non-inbred males. Sperm length variation was significantly greater in the ejaculates of inbred males. Our results show that male ability to achieve normal fertilization success was not depressed under strong inbreeding, but that inbreeding depression in these traits occurred when conditions of sperm competition were generated.

    This paper presents analyses of how the economic recession that started in 2008 has influenced the number of traffic fatalities in OECD countries. Previous studies of the relationship between economic recessions and changes in the number of traffic fatalities are reviewed. Based on these studies, a causal diagram of the relationship between changes of the business cycle and changes in the number of traffic fatalities is proposed. This causal model is tested empirically by means of multivariate analyses and analyses of accident statistics for Great Britain and Sweden. Economic recession, as indicated both by slower growth of, or decline of gross national product, and by increased unemployment is associated with an accelerated decline in the number of traffic fatalities, i.e. a larger decline than the long-term trend that is normal in OECD countries. The principal mechanisms bringing this about are a disproportionate reduction of driving among high-risk drivers, in particular young drivers and a reduction of fatality rate per kilometre of travel, probably attributable to changes in road user behaviour that are only partly observable. The total number of vehicle kilometres of travel did not change very much as a result of the recession. The paper is based on an ITF-report that presents the analyses in greater detail.

    Public health concerns regarding childhood obesity and sedentary behavior make investigations of children's physical activity (PA) promotion crucial. School recess, a highly discretional time, plays a central role in shaping children's activity preferences. Participants included 40 children (30 girls, 10 boys) from fourth and fifth grades, categorized as low active during recess (<26% moderate-to-vigorous PA [MVPA]). PA was measured via accelerometer (Actigraph wGT3X+) and activity choice gauged through a self-report measure over a 3-day period. To assess attitudes and perceptions of recess, individual interviews were conducted. Accelerometer data were analyzed into minutes and percentage of MVPA; interviews were transcribed verbatim and analyzed utilizing open and axial coding. Participants were active for 18% of recess, choosing activities that were primarily individual-based. Interview data showed low active children attribute recess enjoyment to social interaction and time away from schoolwork as well as an intention to avoid other children who were unkind and/or caused social conflict. This study supports the importance of gaining a child's perspective of their own behavior, particularly those children classified as less active. Findings add a unique contribution to school health research through an innovative, child-centered approach to explore perceptions of PA. © 2018, American School Health Association.

    2004-05-01

    Male hybrids between Anopheles gambiae and An. arabiensis suffer from hybrid sterility, and inviability effects are sometimes present as well. We examined the genetic basis of these reproductive barriers between the two species, using 21 microsatellite markers. Generally, recessive inviability effects were found on the X chromosome of gambiae that are incompatible with at least one factor on each arabiensis autosome. Inviability is complete when the gambiae and arabiensis inviability factors are hemi- or homozygous. Using a QTL mapping approach, regions that contribute to male hybrid sterility were also identified. The X chromosome has a disproportionately large effect on male hybrid sterility. Additionally, several moderate-to-large autosomal QTL were found in both species. The effect of these autosomal QTL is contingent upon the presence of an X chromosome from the other species. Substantial regions of the autosomes do not contribute markedly to male hybrid sterility. Finally, no evidence for epistatic interactions between conspecific sterility loci was found.

    Economic recessions have been linked to adult health, but few studies have examined how recessions influence the health of young children. This study examines the impact of life transitions linked to the financial crisis in Ireland on the health of young children. Data came from the Growing Up in Ireland Infant Cohort Study (n = 11,134), which assessed children before (2008), during (2011), and after (2013) the recession and incorporated questions on the impacts of the financial crisis on families. Using fixed effects models to control for confounding, we found that a reduction in welfare benefits during the recession was associated with a significant increase in the risk of asthma (β = 0.0136, 95% confidence interval (95% CI): 0.0062, 0.0328) and atopy (β = 0.0161, 95% CI: 0.0026, 0.0297). While parental job loss was not associated with child health, a reduction in working hours was associated with increased reports of fair or poor child health (β = 0.0235, 95% CI: 0.0041, 0.0429), as were difficulties affording basics (β = 0.0193, 95% CI: 0.0005, 0.0381). Results suggest that failing to protect vulnerable families and children during economic recessions may have long-lasting implications for child health. © The Author(s) 2018.

    2011-09-01

    A 7-year-old male miniature schnauzer dog with unilateral cryptorchidism was presented for elective orchiectomy. Surgery to remove the cryptorchid testis revealed a fully formed uterus with horns attached to both testis and the body and cervix terminating at the prostate gland. The gross and microscopic diagnosis for the genital tract was persistent Müllerian duct syndrome with unilateral cryptorchidism. Additional associated lesions included cystic endometrial hyperplasia and a solitary, intratubular seminoma within the undescended testis. Persistent Müllerian duct syndrome is rare among domestic animals but is more common in miniature schnauzer dogs because of inheritance as an autosomal recessive trait.

    Abstract Charcot–Marie–Tooth disease is a group of hereditary peripheral neuropathies that share clinical characteristics of progressive distal muscle weakness and atrophy, foot deformities, distal sensory loss, as well as diminished tendon reflexes. Hundreds of causative DNA changes have been found, but much of the genetic basis of the disease is still unexplained. Mutations in the ALS5/SPG11/ KIAA1840 gene are a frequent cause of autosomal recessive hereditary spastic paraplegia with thin corpus callosum and peripheral axonal neuropathy, and account for ∼40% of autosomal recessive juvenile amyotrophic lateral sclerosis. The overlap of axonal Charcot–Marie–Tooth disease with both diseases, as well as the common autosomal recessive inheritance pattern of thin corpus callosum and axonal Charcot–Marie–Tooth disease in three related patients, prompted us to analyse the ALS5/SPG11/ KIAA1840 gene in affected individuals with autosomal recessive axonal Charcot–Marie–Tooth disease. We investigated 28 unrelated families with autosomal recessive axonal Charcot–Marie–Tooth disease defined by clinical, electrophysiological, as well as pathological evaluation. Besides, we screened for all the known genes related to axonal autosomal recessive Charcot–Marie-Tooth disease (CMT2A2/HMSN2A2/ MFN2 , CMT2B1/ LMNA , CMT2B2/ MED25 , CMT2B5/ NEFL , ARCMT2F/dHMN2B/ HSPB1 , CMT2K/ GDAP1 , CMT2P/ LRSAM1 , CMT2R/ TRIM2 , CMT2S/ IGHMBP2 , CMT2T/ HSJ1 , CMTRID/ COX6A1 , ARAN-NM/ HINT and GAN/ GAN ), for the genes related to autosomal recessive hereditary spastic paraplegia with thin corpus callosum and axonal peripheral neuropathy (SPG7/ PGN , SPG15/ ZFYVE26, SPG21/ ACP33 , SPG35/ FA2H , SPG46/ GBA2 , SPG55/ C12orf65 and SPG56/ CYP2U1 ), as well as for the causative gene of peripheral neuropathy with or without agenesis of the corpus callosum ( SLC12A6 ) .

    Gregory, L. C.; Humayun, K. N.; Turton, J. P. G.; McCabe, M. J.; Rhodes, S. J.

    2015-01-01

    Background: LHX4 encodes a member of the LIM-homeodomain family of transcription factors that is required for normal development of the pituitary gland. To date, only incompletely penetrant heterozygous mutations in LHX4 have been described in patients with variable combined pituitary hormone deficiencies. Objective/Hypothesis: To report a unique family with a novel recessive variant in LHX4 associated with a lethal form of congenital hypopituitarism that was identified through screening a total of 97 patients. Method: We screened 97 unrelated patients with combined pituitary hormone deficiency, including 65% with an ectopic posterior pituitary, for variants in the LHX4 gene using Sanger sequencing. Control databases (1000 Genomes, dbSNP, Exome Variant Server, ExAC Browser) were consulted upon identification of variants. Results: We identified the first novel homozygous missense variant (c.377C>T, p.T126M) in two deceased male patients of Pakistani origin with severe panhypopituitarism associated with anterior pituitary aplasia and posterior pituitary ectopia. Both were born small for gestational age with a small phallus, undescended testes, and mid-facial hypoplasia. The parents' first-born child was a female with mid-facial hypoplasia (DNA was unavailable). Despite rapid commencement of hydrocortisone and T4 in the brothers, all three children died within the first week of life. The LHX4(p.T126M) variant is located within the LIM2 domain, in a highly conserved location. The absence of homozygosity for the variant in over 65 000 controls suggests that it is likely to be responsible for the phenotype. Conclusion: We report, for the first time to our knowledge, a novel homozygous mutation in LHX4 associated with a lethal phenotype, implying that recessive mutations in LHX4 may be incompatible with life.

    This study examined trends in smoking and overweight/obesity rates among United States (US) adults ages 40years and older by race and socio-economic status (SES) across three study periods; pre-recession (2003-2005), recession (2007-2009), and post-recession/Affordable Care Act (2010-2012). Data was obtained from the Behavioral Risk Factor Surveillance System (BRFSS), and multivariable regression analysis was used to examine changes in overweight/obesity, smoking, physical activity and smoking cessation rates over the study periods. There were 2,805,957 adults included in the analysis; 65.5% of the study population was overweight/obese, and 33.3% were current smokers. Smoking prevalence increased marginally among those with lower SES (incomesmoking overall decreased in the post-recession (OR: 0.93, 95% CI: 0.92-0.94) and recession (OR: 0.95, 95% CI: 0.94-0.97) periods. Overweight/obesity increased over the study periods, regardless of race, SES or healthcare access, while smoking rates showed significant declines post-recession compared with pre-recession, except in low SES groups. These findings suggest that strategies focused on reducing overweight/obesity and increasing access to smoking cessation services, especially among low-income adults, are needed. Prospective studies are needed to better evaluate the influence of the economic recession and Affordable Care Act on behavioral risk factors. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Background/Aim. Gingival recession progression in clinical practaice has influenced the development of various surgical procedures and techniques for solving esthetic imperfections and subjective difficulties coused by gingival recession. The aim of this study was to verify efficacy of surgical procedures and to compare both of surgical procedures through the keratinized tissue width. Methods. The study included 20 teeth with gingival recesion, Müller class I and II. Ten teeth with gingival recession were treated with connective tissue autotransplants with periosteum in combination with coronary guided surgical flap (CTG group. On the contralateral side 10 teeth with gingival recession were treated with the same surgical procedures but in combination with platelet-rich plasma (CTGPRP group. We measured the keratinized tissue width. For statistical significance we used the Student's t-test. Results. The study reveled a statistical significance in reducing vertical deepress of recession by both used treatments. Root deepness in CTG and CTG-PRP group was 90% and 93.5%, respectively. With both surgical techniques we achieved larger zone of keratinized gingiva but with a wide zone of keratinized tissue in CTG - the PRP group. Conclusion. The concept regeneration technique with PRP and with the stimulating influence of platele activated growth factors results in the regeneration of deep periodontal tissue as an important prerequisite for the successful treatment of gingival recession.

    Autosomal recessive progressive myoclonus epilepsy due to impaired ceramide synthesis is an extremely rare condition, so far reported in a single family of Algerian origin presenting an unusual, severe form of progressive myoclonus epilepsy characterized by myoclonus, generalized tonic-clonic seizures and moderate to severe cognitive impairment, with probable autosomal recessive inheritance. Disease onset was between 6 and 16 years of age. Genetic study allowed to identify a homozygous nonsynonymous mutation in CERS1, the gene encoding ceramide synthase 1, a transmembrane protein of the endoplasmic reticulum (ER), catalyzes the biosynthesis of C18-ceramides. The mutation decreased C18-ceramide levels. In addition, downregulation of CerS1 in neuroblastoma cell line showed activation of ER stress response and induction of proapoptotic pathways. This observation demonstrates that impairment of ceramide biosynthesis underlies neurodegeneration in humans.

    Most severe forms of intellectual disability (ID) have specific genetic causes. Numerous X chromosome gene defects and disease-causing copy-number variants have been linked to ID and related disorders, and recent studies have revealed that sporadic cases are often due to dominant de novo mutations with low recurrence risk. For autosomal recessive ID (ARID) the recurrence risk is high and, in populations with frequent parental consanguinity, ARID is the most common form of ID. Even so, its elucidation has lagged behind. Here we review recent progress in this field, show that ARID is not rare even in outbred Western populations, and discuss the prospects for improving its diagnosis and prevention.

    The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveillance System (BRFSS). Breast and colorectal cancer screening were defined in line with U.S. Preventative Services Task Force guidelines, and survey weighted statistical methods were utilized to analyze trends in cancer screening among 1,858,572 BRFSS participants. Overall, 83% of women received mammograms in the past 2 years, while 95% of adults received colorectal cancer screening in the past 10 years. Compared with the pre-recession period, the odds of colorectal screening within 5 years were slightly higher during the recession (OR: 1.05, 95% CI: 1.03-1.08) but significantly lower in the post-recession/ACA period (OR: 0.73, 95% CI: 0.72-0.75). Odds of mammography screening were lower during (OR: 0.94,95% CI: 0.91-0.96) and post-recession/ACA period (OR: 0.80, 95% CI: 0.78-0.82). Breast cancer screening rates declined in the recession and post-recession, while colorectal cancer screening rates increased during the recession and decreased post-recession. Low SES adults and those without healthcare coverage were the least likely to receive screening.

    Full Text Available Daily streamflow data were analysed to assess which climate and terrain factors best explain streamflow response in 183 Australian catchments. Assessed descriptors of catchment response included the parameters of fitted baseflow models, and baseflow index (BFI, average quick flow and average baseflow derived by baseflow separation. The variation in response between catchments was compared with indicators of catchment climate, morphology, geology, soils and land use. Spatial coherence in the residual unexplained variation was investigated using semi-variogram techniques. A linear reservoir model (one parameter; recession coefficient produced baseflow estimates as good as those obtained using a non-linear reservoir (two parameters and for practical purposes was therefore considered an appropriate balance between simplicity and explanatory performance. About a third (27–34% of the spatial variation in recession coefficients and BFI was explained by catchment climate indicators, with another 53% of variation being spatially correlated over distances of 100–150 km, probably indicative of substrate characteristics not captured by the available soil and geology data. The shortest recession half-times occurred in the driest catchments and were attributed to intermittent occurrence of fast-draining (possibly perched groundwater. Most (70–84% of the variation in average baseflow and quick flow was explained by rainfall and climate characteristics; another 20% of variation was spatially correlated over distances of 300–700 km, possibly reflecting a combination of terrain and climate factors. It is concluded that catchment streamflow response can be predicted quite well on the basis of catchment climate alone. The prediction of baseflow recession response should be improved further if relevant substrate properties were identified and measured.

    This issue of Energy Detente finds that the economic recession and very low prices for natural gas have cut US use of oil and reduced its oil-import dependency. The period 1985 through 1991 is examined by petroleum product. The 1991 decline in crude oil imports is felt to be an anomaly that will reverse itself in the short term; it was caused by the recession and the flurry of additional production during the Persian Gulf conflict. This issue also presents the following: (1) The ED Refining Netback Data Series for the US Gulf and West Coasts, Rotterdam, and Singapore as of April 10, 1992; and (2) the ED Fuel Price/Tax Series for countries of the Western Hemisphere, April 1992 Edition

    2017-04-01

    In this study, a gallium nitride (GaN) high electron mobility transistor (HEMT) with recessed insulator and barrier is reported. In the proposed structure, insulator is recessed into the barrier at the drain side and barrier is recessed into the buffer layer at the source side. We study important device characteristics such as electric field, breakdown voltage, drain current, maximum output power density, gate-drain capacitance, short channel effects and DC transconductance using two-dimensional and two-carrier device simulator. Recessed insulator in the drain side of the proposed structure reduces maximum electric field in the channel and therefore increases the breakdown voltage and maximum output power density compared to the conventional counterpart. Also, gate-drain capacitance value in the proposed structure is less than that of the conventional structure. Overall, the proposed structure reduces short channel effects. Because of the recessed regions at both the source and the drain sides, the average barrier thickness of the proposed structure is not changed. Thus, the drain current of the proposed structure is almost equivalent to that of the conventional transistor. In this work, length ( L r) and thickness ( T r) of the recessed region of the barrier at the source side are the same as those of the insulator at the drain side.

    This paper examines the impact that the Great Recession had on individuals' health behaviours and risk factors such as diet choices, smoking, alcohol consumption, and Body Mass Index, as well as on intermediate health outcomes in England. We exploit data on about 9000 households from the Health Survey for England for the period 2001-2013 and capture the change in macroeconomic conditions using regional unemployment rates and an indicator variable for the onset of the recession. Our findings indicate that the recession is associated with a decrease in the number of cigarettes smoked - which translated into a moderation in smoking intensity - and a reduction in alcohol intake. The recession indicator itself is associated with a decrease in fruit intake, a shift of the BMI distribution towards obesity, an increase in medicines consumption, and the likelihood of suffering from diabetes and mental health problems. These associations are often stronger for the less educated and for women. When they exist, the associations with the unemployment rate (UR) are nevertheless similar before and after 2008. Our results suggest that some of the health risks and intermediate health outcomes changes may be due to mechanisms not captured by worsened URs. We hypothesize that the uncertainty and the negative expectations generated by the recession may have influenced individual health outcomes and behaviours beyond the adjustments induced by the worsened macroeconomic conditions. The net effect translated into the erosion of the propensity to undertake several health risky behaviours but an exacerbation of some morbidity indicators. Overall, we find that the recession led to a moderation in risky behaviours but also to worsening of some risk factors and health outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Mango (Mangifera indica L.) is called "king of fruits" due to its sweetness, richness of taste, diversity, large production volume and a variety of end usage. Despite its huge economic importance genomic resources in mango are scarce and genetics of useful horticultural traits are poorly understood. Here we generated deep coverage leaf RNA sequence data for mango parental varieties 'Neelam', 'Dashehari' and their hybrid 'Amrapali' using next generation sequencing technologies. De-novo sequence assembly generated 27,528, 20,771 and 35,182 transcripts for the three genotypes, respectively. The transcripts were further assembled into a non-redundant set of 70,057 unigenes that were used for SSR and SNP identification and annotation. Total 5,465 SSR loci were identified in 4,912 unigenes with 288 type I SSR (n ≥ 20 bp). One hundred type I SSR markers were randomly selected of which 43 yielded PCR amplicons of expected size in the first round of validation and were designated as validated genic-SSR markers. Further, 22,306 SNPs were identified by aligning high quality sequence reads of the three mango varieties to the reference unigene set, revealing significantly enhanced SNP heterozygosity in the hybrid Amrapali. The present study on leaf RNA sequencing of mango varieties and their hybrid provides useful genomic resource for genetic improvement of mango.

    Satellite and ground observations detected large variability in nitrogen oxides (NOx) during the 2008 economic recession, but the impact of the recession on air quality has not been quantified. This study combines observed NOx trends and a regional chemical transport model to quantify the impact of the recession on surface ozone (O3) levels over the continental United States. The impact is quantified by simulating O3 concentrations under two emission scenarios: business-as-usual (BAU) and recession. In the BAU case, the emission projection from the Cross-State Air Pollution Rule is used to estimate the would-be NOx emission level in 2011. In the recession case, the actual NO2 trends observed from Air Quality System ground monitors and the Ozone Monitoring Instrument on the Aura satellite are used to obtain realistic changes in NOx emissions. The model prediction with the recession effect agrees better with ground O3 observations over time and space than the prediction with the BAU emission. The results show that the recession caused a 12ppbv decrease in surface O3 concentration over the eastern United States, a slight increase (0.51ppbv) over the Rocky Mountain region, and mixed changes in the Pacific West. The gain in air quality benefits during the recession, however, could be quickly offset by the much slower emission reduction rate during the post-recession period.

    2011-09-01

    There has been limited research on how recessions (or more generally, the strength of the economy) affect drug use and the related outcome of drug selling. This is especially important, given the current economic crisis. This paper aims to use a conceptual framework, previous research, and new research to predict how the current economic crisis may be affecting youth drug selling and drug use. A conceptual framework to understand how a recession could affect youth drug selling and drug use is presented, along with a review of the literature on empirical investigations on how the strength of the economy affects these behaviours among teenagers. In addition, new analyses for young adults are presented. The conceptual framework postulates that a recession would have direct positive effects on the prevalence of youth drug selling but ambiguous direct effects on youth drug use. The conceptual framework also postulates that drug selling and drug use are inter-connected at the individual level and the aggregate level. Thus, any effect of a recession on one would likely affect the other in the same direction. The limited empirical evidence indicates that both drug selling and drug use among youth are higher when the economy is weaker. The current economic crisis will likely increase both youth drug selling and drug use relative to what they would have otherwise been. Published by Elsevier B.V.

    We report on a family with a not earlier described multiple congenital malformation. Several male family members suffer from laryngeal obstruction caused by bilateral vocal cord paralysis, outer and middle ear deformity with conductive and sensorineural hearing loss, facial dysmorphisms, and underdeveloped shoulder musculature. The affected female members only have middle ear deformity and hearing loss. The pedigree is suggestive of an X-linked recessive inheritance pattern. SNP-array revealed a deletion and duplication on Xq28 in the affected family members. A possible aetiology is a neurocristopathy with most symptoms expressed in structures derived from branchial arches. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    2012-01-01

    Charcot-Marie-Tooth (CMT) disease, a hereditary motor and sensory neuropathy that comprises a complex group of more than 50 diseases, is the most common inherited neuropathy. CMT is generally divided into demyelinating forms, axonal forms and intermediate forms. CMT is also characterized by a wide genetic heterogeneity with 29 genes and more than 30 loci involved. The most common pattern of inheritance is autosomal dominant (AD), although autosomal recessive (AR) forms are more frequent in Mediterranean countries. In this chapter we give an overview of the associated genes, mechanisms and epidemiology of AR-CMT forms and their associated phenotypes.

  20. Genetic dissection of hybrid incompatibilities between Drosophila simulans and D. mauritiana. I. Differential accumulation of hybrid male sterility effects on the X and autosomes.

    2003-08-01

    The genetic basis of hybrid incompatibility in crosses between Drosophila mauritiana and D. simulans was investigated to gain insight into the evolutionary mechanisms of speciation. In this study, segments of the D. mauritiana third chromosome were introgressed into a D. simulans genetic background and tested as homozygotes for viability, male fertility, and female fertility. The entire third chromosome was covered with partially overlapping segments. Many segments were male sterile, while none were female sterile or lethal, confirming previous reports of the rapid evolution of hybrid male sterility (HMS). A statistical model was developed to quantify the HMS accumulation. In comparison with previous work on the X chromosome, we estimate that the X has approximately 2.5 times the density of HMS factors as the autosomes. We also estimate that the whole genome contains approximately 15 HMS "equivalents"-i.e., 15 times the minimum number of incompatibility factors necessary to cause complete sterility. Although some caveats for the quantitative estimate of a 2.5-fold density difference are described, this study supports the notion that the X chromosome plays a special role in the evolution of reproductive isolation. Possible mechanisms of a "large X" effect include selective fixation of new mutations that are recessive or partially recessive and the evolution of sex-ratio distortion systems.

    2015-04-01

    To identify the best available evidence for the effect of toothbrushing on the initiation and progression of gingival recession and non-carious cervical lesions (NCCLs). A protocol was developed for the questions: Does traumatic toothbrushing, compared to normal toothbrushing, lead to an increased prevalence of non-inflammatory gingival recession? [FQ1] and NCCLs? [FQ2]. The search covered four electronic databases. Bibliographies of review articles, relevant texts, World and European Workshops were screened. Hand searches were performed of the Journals of Clinical Periodontology, Periodontology, Periodontal Research and IADR abstracts. A meta-analysis included 159 subjects and showed that subjects who used MTBs (manual toothbrush) had greater gingival recession after 12 months when compared with those using PTBs (powered toothbrush). Thirteen cross-sectional studies identified the most frequent toothbrushing factors associated with gingival recession as being toothbrushing frequency, a horizontal or scrub toothbrushing method, bristle hardness, toothbrushing duration and the frequency of changing a toothbrush. The principal toothbrushing factors associated with NCCLs were toothbrushing method and frequency. The data to support or refute the association between toothbrushing and gingival recession and NCCLs remain largely inconclusive. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available The aim of this study was to determine physical activity levels of children during school recess, taking into account children’s perceptions as well as observations during recess. A mixed method was used, including the System for Observing Play and Leisure Activity in Youth (SOPLAY and focus groups. Participants included students from 3 public schools with regular and alternating schedules, who were observed during their school breaks. In addition, focus groups were held and descriptive statistics were used.  A factorial variance test (2x2 was also used to determine if there were differences between levels of moderate-vigorous physical activity among school types. Results of focus groups were organized into categories. Students exhibited 47.98 sedentary activity and 52.02 moderate-vigorous physical activity during school recess, with girls being more sedentary than boys. Students with an alternating schedule are more active than those with a regular schedule. Participants perceived reduced space to play and little support from teachers as barriers to do physical activity. In conclusion, this study showed that a little over 50% of students perform physical activity during school recess, with children in alternating schedules being more active than those with a regular schedule. Participants perceive that school environment does not favor physical activity, due to environmental barriers. Based on the results of this study, physical activity should be promoted during school recess, taking into consideration barriers in natural, social, physical, and organizational environments.

  4. Understanding the reasons why tourists visit the Kruger National Park during a recession

    Full Text Available The 2008 and 2009 recession increased pressure on travellers to cut costs on luxury items, such as going on holiday, and this has led to a global tourism decline of 8%. This, however, was not the case in the Kruger National Park (KNP in South Africa where a sustained 1.6% accommodation unit occupancy growth was experienced. In order to sustain this growth, it is of the utmost importance to determine why people still visited the Park during this period. Thus the aim of the study was to determine why people still visited the KNP amidst the 2008 and 2009 economic recession. A total of 355 completed questionnaires were obtained at the Park during 15 December 2009 – 20 December 2009 (high season after which various analyses (including factor analysis were conducted. Six motives were identified and ‘escape’, ‘wildlife experience’ and ‘family benefits’ were rated most important. Push factors were more dominant to the extent that visitors regard taking a holiday to the Park as a necessity. It furthermore seems that visitors adapt their spending behaviour at the Park to still be able to afford the visit. This was the first time that research was conducted at a national park during a recession period and this information is important for South African National Parks, seeing as it provides a better understanding of visitors’ behaviour as well as feeling towards the Park (especially during recession, and leads to improved niche marketing and a competitive advantage. This research also provides a better understanding of visitors’ behaviour during economic downturns.

  5. Alcohol taxation, economic recession, and mortality changes in five European countries

    Directory of Open Access Journals (Sweden)

    Andreeva, Tatiana

    2012-07-01

    Full Text Available BACKGROUND: Since 2008 some mortality decline is observed in several European countries including Latvia, Lithuania, and Ukraine. We hypothesized that this decline could be caused by decreased alcohol use facilitated by both economic recession and alcohol taxation. This study aimed to check this hypothesis.METHODS: Besides the abovementioned countries which suffered from the economic recession and have increased alcohol excise taxes, we considered data from the WHO-Euro mortality database for Poland which did not suffer from GDP decline and Ireland which decreased alcohol excise in 2009. Both per capita GDP growth change (from -18% in Latvia to +2% in Poland and alcohol excise change (from -20% in Ireland to +60% in Ukraine compared to 2008 rates were considered as independent variables. The outcome was percentage of real mortality decline compared to 2009 extrapolation of 2000-2008 trends, which were built using linear regression separately for major groups of death causes earlier shown to have changed in 2009. Population groups aged 30-59 were considered as those whose mortality declined most.RESULTS: Ten percent increase in alcohol excise taxes was associated with 9.4% decline in respiratory mortality from expected rate, 5.7% decline in causes of death related to nervous system, 4.9% decline in external causes of death, 4.8% decline in circulatory system deaths, 3.5% decline in infectious diseases as causes of death. Cardiovascular mortality decline was marginally associated with measurements of economic crisis (0.7% decline per 1% GDP fall.DISCUSSION: During the economic recession, the portion of all-causes mortality that has declined is most likely alcohol-related. Death causes that have mostly declined during the recession are more strongly associated with alcohol taxation than with GDP fall. Cardiovascular deaths decline related to the economic crisis could have been related to diet changes including smaller proportion of fatty and

    This pilot study aimed at investigating the effectiveness of lowering playground density on increasing children's physical activity and decreasing sedentary time. Also the feasibility of this intervention was tested. Data were collected in September and October 2012 in three Belgian schools in 187, 9-12 year old children. During the intervention, playground density was decreased by splitting up recesses and decreasing the number of children sharing the playground. A within-subject design was used. Children wore accelerometers during the study week. Three-level (class - participant - measurement (baseline or intervention)) linear regression models were used to determine intervention effects. After the intervention week the school principals filled out a questionnaire concerning the feasibility of the intervention. The available play space was 12.18 ± 4.19 m²/child at baseline and increased to 24.24 ± 8.51 m²/child during intervention. During the intervention sedentary time decreased (-0.58 min/recess; -3.21%/recess) and moderate-to-vigorous physical activity (+1.04 min/recess; +5.9%/recess) increased during recess and during the entire school day (sedentary time: -3.29%/school day; moderate-to-vigorous physical activity +1.16%/school day). All principals agreed that children enjoyed the intervention; but some difficulties were reported. Lowering playground density can be an effective intervention for decreasing children's sedentary time and increasing their physical activity levels during recess; especially in least active children.

  7. The impact of the macroeconomy on health insurance coverage: evidence from the Great Recession.

    This paper investigates the impact of the macroeconomy on the health insurance coverage of Americans using panel data from the Survey of Income and Program Participation for 2004-2010, a period that includes the Great Recession of 2007-2009. We find that a one percentage point increase in the state unemployment rate is associated with a 1.67 percentage point (2.12%) reduction in the probability that men have health insurance; this effect is strongest among college-educated, white, and older (50-64 years old) men. For women and children, health insurance coverage is not significantly correlated with the unemployment rate, which may be the result of public health insurance acting as a social safety net. Compared with the previous recession, the health insurance coverage of men is more sensitive to the unemployment rate, which may be due to the nature of the Great Recession.

    Genetic associations involving both rare and common alleles have been reported for schizophrenia but there have been no systematic scans for rare recessive genotypes using fully phased trio data. Here, we use exome sequencing in 604 schizophrenia proband-parent trios to investigate the role of recessive (homozygous or compound heterozygous) nonsynonymous genotypes in the disorder. The burden of recessive genotypes was not significantly increased in probands at either a genome-wide level or in any individual gene after adjustment for multiple testing. At a system level, probands had an excess of nonsynonymous compound heterozygous genotypes (minor allele frequency, MAF ⩽ 1%) in voltage-gated sodium channels (VGSCs; eight in probands and none in parents, P = 1.5 × 10(-)(4)). Previous findings of multiple de novo loss-of-function mutations in this gene family, particularly SCN2A, in autism and intellectual disability provide biological and genetic plausibility for this finding. Pointing further to the involvement of VGSCs in schizophrenia, we found that these genes were enriched for nonsynonymous mutations (MAF ⩽ 0.1%) in cases genotyped using an exome array, (5585 schizophrenia cases and 8103 controls), and that in the trios data, synaptic proteins interacting with VGSCs were also enriched for both compound heterozygosity (P = 0.018) and de novo mutations (P = 0.04). However, we were unable to replicate the specific association with compound heterozygosity at VGSCs in an independent sample of Taiwanese schizophrenia trios (N = 614). We conclude that recessive genotypes do not appear to make a substantial contribution to schizophrenia at a genome-wide level. Although multiple lines of evidence, including several from this study, suggest that rare mutations in VGSCs contribute to the disorder, in the absence of replication of the original findings regarding compound heterozygosity, this conclusion requires evaluation in a larger sample of trios.

    Many children, in particular girls, do not reach the recommended amount of daily physical activity. School recess provides an opportunity for both boys and girls to be physically active, but barriers to recess physical activity are not well understood. This study explores gender differences in children's perceptions of barriers to recess physical activity. Based on the socio-ecological model four types of environmental barriers were distinguished: natural, social, physical and organizational environment. Data were collected through 17 focus groups (at 17 different schools) with in total 111 children (53 boys) from fourth grade, with a mean age of 10.4 years. The focus groups included an open group discussion, go-along group interviews, and a gender segregated post-it note activity. A content analysis of the post-it notes was used to rank the children's perceived barriers. This was verified by a thematic analysis of transcripts from the open discussions and go-along interviews. The most frequently identified barriers for both boys and girls were weather, conflicts, lack of space, lack of play facilities and a newly-found barrier, use of electronic devices. While boys and girls identified the same barriers, there were both inter- and intra-gender differences in the perception of these barriers. Weather was a barrier for all children, apart from the most active boys. Conflicts were perceived as a barrier particularly by those boys who played ballgames. Girls said they would like to have more secluded areas added to the school playground, even in large schoolyards where lack of space was not a barrier. This aligned with girls' requests for more "hanging-out" facilities, whereas boys primarily wanted activity promoting facilities. Based on the results from this study, we recommend promoting recess physical activity through a combination of actions, addressing barriers within the natural, social, physical and organizational environment.

    NDST1 was recently proposed as a candidate gene for autosomal recessive intellectual disability in two families. It encodes a bifunctional GlcNAc N-deacetylase/N-sulfotransferase with important functions in heparan sulfate biosynthesis. In mice, Ndst1 is crucial for embryonic development and homozygous null mutations are perinatally lethal. We now report on two additional unrelated families with homozygous missense NDST1 mutations. All mutations described to date predict the substitution of conserved amino acids in the sulfotransferase domain, and mutation modeling predicts drastic alterations in the local protein conformation. Comparing the four families, we noticed significant overlap in the clinical features, including both demonstrated and apparent intellectual disability, muscular hypotonia, epilepsy, and postnatal growth deficiency. Furthermore, in Drosophila, knockdown of sulfateless, the NDST ortholog, impairs long-term memory, highlighting its function in cognition. Our data confirm NDST1 mutations as a cause of autosomal recessive intellectual disability with a distinctive phenotype, and support an important function of NDST1 in human development. © 2014 Wiley Periodicals, Inc.

  11. More countries in recession: Oil supply looking for demand

    Crude oil prices fell dramatically during the fourth quarter of 1992. Refiners are reevaluating their positions to adjust to low demand growth worldwide. The only bright spot appears to be the United States' emergence from its economic recession. However, Japan and Germany are experiencing their own economic recessions, and crude oil supplies show no sign of tightening. Crude oil futures prices have fallen by more than 15% as of January 8, 1993 compared to October 1, 1992. Although the American Petroleum Institute (API) found increases in oil demand during October and November 1992, the increases are attributed to colder weather and the weak 1991 demand that was used for comparison. This issue identifies current factors at work affecting U.S. refining margins and product values, and offers a first quarter 1993 outlook. All data featured in graphs and text come from the Energy detente Refinery Netback Data Series published in each issue, in which gasoline and diesel No. 2 are Lundberg Survey unbranded racks instead of spot quotations.

    This study examines the impact of the "Great Recession" (from December 2007 to June 2009) on 8th and 10th graders in the USA, using annual nationally representative data from the Monitoring the Future study. Historical changes in youth adjustment (self-esteem, depressed mood, risk taking, aggression and property crime), school achievement (grade point average [GPA], time spent on homework and educational expectations) and structured and unstructured activities (volunteering, employment, sports and evenings out for fun) were examined between 1991 and 2014. Overall, there were only slight changes in mean levels of adjustment, achievement and most youth activities. However, the percentage of youth working during the school year did decline during the Great Recession. Several longer-term trends were also evident, though not directly tied to the Great Recession. These include an increase in GPA, a decrease in time spent on homework, rising educational expectations and more time spent volunteering. Future work should assess how the shift to unpaid work activities (e.g. volunteering and internships) among youth is impacting the transition from school to work in the contemporary economy, and whether the Great Recession had deleterious impacts for younger children or among youth whose parents lost work or had their homes foreclosed. © 2016 International Union of Psychological Science.

  13. Why Did People Move During the Great Recession? The Role of Economics in Migration Decisions

    Full Text Available Labor migration offers an important mechanism to reallocate workers when there are regional differences in employment conditions. Whereas conventional wisdom suggests migration rates should increase during recessions as workers move out of areas that are hit hardest, initial evidence suggested that overall migration rates declined during the Great Recession, despite large regional differences in unemployment and growth rates. In this paper we use data from the American Community Survey to analyze internal migration trends before and during the economic downturn. First, we find only a modest decline in the odds of adults leaving distressed labor market areas during the Great Recession, which may result in part from challenges related to the housing price crash. Second, we estimate conditional logit models of destination choice for individuals who migrate across labor market areas; we find a substantial effect of economic factors such as labor demand, unemployment, and housing values. We also estimate latent class conditional logit models that test whether there is heterogeneity in preferences for destination characteristics among migrants. Over all, the latent class models suggest that roughly equal percentages of migrants were motivated by economic factors before and during the Great Recession. We conclude that fears of dramatic declines in labor migration seem to be unsubstantiated.

    This special section brings together leading experts in psychology and sociology to examine the consequences of the Great Recession for young people's values, achievement orientation, and outlook to the future. Evidence from Europe and the United States suggests that the impact of the recession varies for distinct outcomes and by age, the latter pointing to potential sensitive periods for interventions. Although the direct effects of the recession are not strong, they accelerate pre-existing trends towards more prolonged and precarious transitions to independence, and are likely to bring with them long-term scarring with respect to health and well-being. While feelings of self-confidence and self-worth have eroded, young people continue to subscribe to the "American Dream," the belief that in principle it is possible to make it - even if limitations to one's own capabilities are recognised. Trust in institutions has declined, but support and concern for others have increased, suggesting that in times of economic hardship and uncertainty social relationships become more salient. Young people's response to the recession appears to be less of a "me-first" reaction than "let's help each other": a form of "collective agency" to counter the inadequacy of social safety nets. © 2016 International Union of Psychological Science.

    The school environment influences children's opportunities for physical activity participation. The aim of the present study was to assess objectively measured school recess physical activity in children from high and low socioeconomic backgrounds. Four hundred and seven children (6-11 years old) from 4 primary schools located in high socioeconomic status (high-SES) and low socioeconomic status (low-SES) areas participated in the study. Children's physical activity was measured using accelerometry during morning and afternoon recess during a 4-day school week. The percentage of time spent in light, moderate, vigorous, very high and in moderate- to very high-intensity physical activity were calculated using age-dependent cut-points. Sedentary time was defined as 100 counts per minute. Boys were significantly (p active than girls. No difference in sedentary time between socioeconomic backgrounds was observed. The low-SES group spent significantly more time in light (p physical activity compared to the high-SES group. High-SES boys and girls spent significantly more time in moderate (p physical activity than low-SES boys. Differences were observed in recess physical activity levels according to socioeconomic background and sex. These results indicate that recess interventions should target children in low-SES schools.

    Full Text Available Gingival recession is a condition that affects a large portion of the young and adult population and negatively affects the aesthetic aspects of the smile. Many factors are related to its development, including orthodontic movement beyond the osseous limits. Many treatment options have been proposed to cover the exposed root surface. The aim of this article was to describe three cases where a subepithelial connective tissue graft was performed, using a microsurgical technique, in the treatment of deep gingival recession after orthodontic treatment. This technique resulted in successful root coverage and keratinized tissue gain, improving the gingival esthetic pattern.

  18. The Great Recession and Its Aftermath: What Role for Structural Changes?

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available The years since the 2009 end of the Great Recession have been disastrous for many workers, particularly those with low human capital or other disadvantages. One explanation attributes this to deficient aggregate labor demand, to which marginal workers are more sensitive. A second attributes it to structural changes. Cyclical explanations imply that if aggregate labor demand is increased then many of the post-2009 patterns will revert to their pre-recession trends. Structural explanations suggest recent experience is the “new normal.” This paper reviews data since 2007 for evidence. I examine wage trends to measure the relative importance of supply and demand. I find little wage pressure before 2015, pointing to demand as the binding constraint. The most recent data show some signs of tightness, but still substantial slack.

    Osteogenesis imperfecta (OI) is a collagen-related disorder associated to dominant, recessive or X-linked transmission, mainly caused by mutations in type I collagen genes or in genes involved in type I collagen metabolism. Among the recessive forms, OI types VII, VIII, and IX are due to mutations in CRTAP, P3H1, and PPIB genes, respectively. They code for the three components of the endoplasmic reticulum complex that catalyzes 3-hydroxylation of type I collagen α1Pro986. Under-hydroxylation of this residue leads to collagen structural abnormalities and results in moderate to lethal OI phenotype, despite the exact molecular mechanisms are still not completely clear. To shed light on these recessive forms, primary fibroblasts from OI patients with mutations in CRTAP (n=3), P3H1 (n=3), PPIB (n=1) genes and from controls (n=4) were investigated by a functional proteomic approach. Cytoskeleton and nucleoskeleton asset, protein fate, and metabolism were delineated as mainly affected. While western blot experiments confirmed altered expression of lamin A/C and cofilin-1, immunofluorescence analysis using antibody against lamin A/C and phalloidin showed an aberrant organization of nucleus and cytoskeleton. This is the first report describing an altered organization of intracellular structural proteins in recessive OI and pointing them as possible novel target for OI treatment. OI is a prototype for skeletal dysplasias. It is a highly heterogeneous collagen-related disorder with dominant, recessive and X-linked transmission. There is no definitive cure for this disease, thus a better understanding of the molecular basis of its pathophysiology is expected to contribute in identifying potential targets to develop new treatments. Based on this concept, we performed a functional proteomic study to delineate affected molecular pathways in primary fibroblasts from recessive OI patients, carrying mutations in CRTAP (OI type VII), P3H1 (OI type VIII), and PPIB (OI type IX) genes

    Children with ASD face enormous challenges in the area of social functioning. Research has shown that impairments in social functioning distinguish this population from both typically developing children and children with disabilities. This study incorporated several evidence-based social skills-teaching procedures (i.e., direct instruction, priming, prompting, peer-mediation, contingent reinforcement, and token economies) directly in the recess setting to increase appropriate social behaviors for four children with ASD (ages 6–8). Elements of Peer Networks and Pivotal Response Training (two types of social skills intervention packages in the literature) were included. Results showed significant increases in social communication between focus children and their peers, as well as generalization of skills to non-intervention recesses. PMID:26312064

    Full Text Available Background/purpose: An ideal therapeutic procedure for the treatment of gingival recession associated with an NCCL has presented a challenge to clinicians. Various dental materials and surgical approaches have been used to manage gingival recessions associated with NCCLs for the most predictable combined surgical/restorative treatment. The objective of this study was to evaluate the treatment of gingival recessions associated with non-carious cervical lesions (NCCL using a modified coronally advanced flap (MCAF in combination with a connective tissue graft (CTG on restored root surfaces. Materials and methods: Twenty-three systemically healthy subjects, who were positive for the presence of three cervical lesions associated with gingival recessions in three different adjacent teeth, were enrolled in the study. The NCCL were each restored prior to surgery by using one of three different materials: nanofilled composite resin (NCR, resin-modified glass ionomer cement (RMGI or giomer. The gingival recession defects were treated by CTG. Results: Inter-group differences were not statistically significant for probing depth (PD, relative recession height (rRH, relative clinical attachment level (rCAL, keratinized tissue width (KTW or keratinized tissue thickness (KTT (p > 0.05 among the groups at any time. The mean percentage of defect coverage was 71.18 ± 23.16% for NCR + CTG group; 71.33 ± 22.33% for RMGI + CTG group; and 64.23 ± 20.33% for giomer + CTG group at 1 year postoperatively (p > 0.05. Conclusion: The combined surgical/restorative treatments provided successful clinical results. Giomer + CTG may be less effective compared to other groups for treatment of gingival recession associated with NCCL.

    During recess, children can be active on a daily basis, making it an important school environmental factor for the promotion of health-related physical activity. The aim of the present study was to investigate the effects of providing game equipment on children's physical activity levels during morning recess and lunch break in elementary schools. Seven elementary schools were randomly assigned to the intervention group (four schools), including 122 children (75 boys, 47 girls, mean age: 10.8 +/- 0.6 years), and to the control group (three schools), including 113 children (46 boys, 67 girls, mean age: 10.9 +/- 0.7 years). Children's activity levels were measured before and three months after providing game equipment, using MTI accelerometers. During lunch break, children's moderate and vigorous physical activity significantly increased in the intervention group (moderate: from 38 to 50%, vigorous: from 10 to 11%), while it decreased in the control group (moderate: from 44 to 39%, vigorous: from 11 to 5%). At morning recess, providing game equipment was effective in increasing children's moderate physical activity (from 41 to 45%), while it decreased in the control group (from 41 to 34%). Providing game equipment during recess periods was found to be effective in increasing children's physical activity levels. This finding suggests that promoting physical activity through game equipment provision during recess periods can contribute to reach the daily activity levels recommended for good health.

  4. Correlation between the Limbus-Insertion Distance of the Lateral Rectus Muscle and Lateral Rectus Recession Surgery in Intermittent Exotropia.

    Full Text Available The aim of this study was to investigate whether the limbus-insertion distance (LID of the lateral rectus (LR muscle can be a useful indicator for predicting the surgical effect of recession surgery in intermittent exotropia (IXT. Patients who underwent unilateral or bilateral LR recession for the basic type of IXT were included. The distance between the corneal limbus and the posterior edge of the insertion of LR muscle (limbus-insertion distance was measured intraoperatively using surgical calipers (graded with 0.25 mm precision. We calculated the actual dose-response effect as the difference between the angle of preoperative deviation and the angle of postoperative deviation, and then divided the figure by the total amount of recession at postoperative months 1, 3, and 6. The correlation between the limbus-insertion distance (LID of LR muscle and each dose-response effect was statistically analyzed. A total of 60 subjects were enrolled in this study. The mean LID of LR muscle was 5.8±0.7 mm. The dose-response effect was 3.2±1.0 prism diopters (PD/mm at postoperative month 1, 3.4±1.0 PD/mm at postoperative month 3, and 3.4±1.1 PD/mm at postoperative month 6. The LID of the LR muscle was significantly correlated with dose-response effects in cases of unilateral and bilateral LR recession at postoperative months 3 and 6 (P = 0.01, <0.01, 0.04 and <0.01 respectively. As the LID of the LR muscle increased by 1 mm, the dose-response effect increased by 0.2PD/mm in unilateral LR recession, and by 0.4 PD/mm in bilateral LR recession at postoperative month 6. In conclusion, the LID of the LR muscle can be used as one predictor of the recession effect to assist in surgical planning for IXT. Moreover, undercorrection at the time of LR recession might be considered in patients with long LID of the LR muscle.

    1986-01-01

    The occurrence of a heritable, multiple intestinal adenocarcinoma (HMIA) was observed in the offspring of an outcross between a male (or female) parent originating from our C57 Black/6M strain and his female (or male) mating counterpart originating from an experimental subline of the same strain, propagated with multigeneration exposure of the male parent to low-level tritium. Multiple intestinal malignancy was observed with a high-expression frequency in all animals examined in five subsequent generations, irrespective of the sex of the initial ascendant originating from the experimental subline, exposed to tritiated water. A digenic inheritance with partial penetrance is postulated, involving at least a two-stage process of tumorigenesis, namely, a dominant mutation at one locus and a second mutation to a recessive which, as long as it remained homozygous, prevented expression of the tumorigenic dominant gene. 10 refs., 2 tabs

  12. The impact of economic recession on infection prevention and control.

    Science.gov (United States)

    O'Riordan, M; Fitzpatrick, F

    2015-04-01

    The economic recession that began in 2007 led to austerity measures and public sector cutbacks in many European countries. Reduced resource allocation to infection prevention and control (IPC) programmes is impeding prevention and control of tuberculosis, HIV and vaccine-preventable infections. In addition, higher rates of infectious disease in the community have a significant impact on hospital services, although the extent of this has not been studied. With a focus on quick deficit reduction, preventive services such IPC may be regarded as non-essential. Where a prevention programme succeeds in reducing disease burden to a low level, its very success can undermine the perceived need for the programme. To mitigate the negative effects of recession, we need to: educate our political leaders about the economic benefits of IPC; better quantify the costs of healthcare-associated infection; and evaluate the effects of budget cuts on healthcare outcomes and IPC activities.

    Autosomal recessive cerebellar ataxias (ARCA) are a complex group of neurodegenerative disorders with great genetic and phenotypic heterogeneity, over 30 genes/loci have been associated with more than 20 different clinical forms of ARCA. Genetic heterogeneity combined with highly variable clinical expression of the cerebellar symptoms and overlapping features complicate furthermore the etiological diagnosis of ARCA. The determination of the most frequent mutations and corresponding ataxias, as well as particular features specific to a population, are mandatory to facilitate and speed up the diagnosis process, especially when an appropriate treatment is available. We explored 166 patients (115 families) refered to the neurology units of Algiers central hospitals (Algeria) with a cerebellar ataxia phenotype segregating as an autosomal recessive pattern of inheritance. Genomic DNA was extracted from peripheral blood samples and mutational screening was performed by PCR and direct sequencing or by targeted genomic capture and massive parallel sequencing of 57 genes associated with inherited cerebellar ataxia phenotypes. In this work we report the clinical and molecular results obtained on a large cohort of Algerian patients (110 patients/76 families) with genetically determined autosomal recessive ataxia, representing 9 different types of ARCA and 23 different mutations, including 6 novel ones. The five most common ARCA in this cohort were Friedreich ataxia, ataxia with isolated vitamin E deficiency, ataxia with oculomotor apraxia type 2, autosomal recessive spastic ataxia of Charlevoix-Saguenay and ataxia with oculomotor apraxia type 1. We report here a large cohort of patients with genetically determined autosomal recessive ataxia and the first study of the genetic context of ARCA in Algeria. This study showed that in Algerian patients, the two most common types of ataxia (Friedreich ataxia and ataxia with isolated vitamin E deficiency) coexist with forms that may be

    Full Text Available The global economy is currently facing one of the longest recessions in the past fifty years. The way out of the Great recession requires active measures to stimulate the demand in the economy. However, distinctive features of the recent recession are the significant amount of a debt burden on national budgets, low inflation contributes to an increasing potential of a monetary policy to ensure economic recovery, but require from the central bank an unconventional approach to achieve the broad set of goals. One of the tools of so-called unconventional monetary policy is quantitative easing. The USA experience of applying the unconventional monetary policy suggests that the quantitative easing is an effective tool for warming up the economy in the recession phase, especially in the medium terms, but it causes challenges for developing of the national economy (credit risk deterioration of the central bank's portfolio, rising commodity prices, flows of speculative capital and like "secondary effects" challenges for developing of the global economy (interest rates volatility, price bubbles on stock markets, currency risks, etc..

    Trends in the labor market, as a result of global economic recession, are characterized by reduction of manpower activity, decreased number of employed and increased number of unemployed persons. As the result of economic recession more then million workplaces are expected to be lost in the European Union. The aim of this study was to analyze the influence of economic recession on labor market in general and healthcare labor market in Croatia. In Q1/2009, the number of employed persons in the European Union declined by -1.2% compared to the same quarter of 2008, while in Croatia the number of employed persons declined by -0.4%. The comparison of quarterly employment rate in Croatia and the European Union in the period from Q2/2008 to Q1/2009 was not significantly different (p = 0.169, df = 6, t = 1.564, Student t test). Average unemployment rate in Q1/2009 in the European Union was 8.1% +/- 0.3 and it was increased by 9.4% compared to Q4/2008, while in Croatia the average unemployment rate in Q1/2009 was 8.4% +/- 0.1 and it was increased by 3.3% compared to Q4/2008. Monthly changes of unemployment rates compared between the European Union and Croatia in the six month period (Q4/2008 and Q1/2009) was significantly different (p = 0.001, df = 10, t = 4.425, Student t test). In Croatian health care system in Q1/2009 the number of employed person increased by 0.7% compared to Q1/2008, while the number of unemployed persons in the same period was reduced by -1.0%. Trends in the labor market in Croatia follow the global trends in the labor market in times of economic recession, although the increase in unemployment in Croatia was slower than in the countries of the European Union. As a result of Croatian healthcare system organization, system of financing, supply and demand on healthcare labor market, healthcare workforce in Croatia was less affected by recession than workforce in Croatia in general.

    Mango (Mangifera indica L.) is called “king of fruits” due to its sweetness, richness of taste, diversity, large production volume and a variety of end usage. Despite its huge economic importance genomic resources in mango are scarce and genetics of useful horticultural traits are poorly understood. Here we generated deep coverage leaf RNA sequence data for mango parental varieties ‘Neelam’, ‘Dashehari’ and their hybrid ‘Amrapali’ using next generation sequencing technologies. De-novo sequence assembly generated 27,528, 20,771 and 35,182 transcripts for the three genotypes, respectively. The transcripts were further assembled into a non-redundant set of 70,057 unigenes that were used for SSR and SNP identification and annotation. Total 5,465 SSR loci were identified in 4,912 unigenes with 288 type I SSR (n ≥ 20 bp). One hundred type I SSR markers were randomly selected of which 43 yielded PCR amplicons of expected size in the first round of validation and were designated as validated genic-SSR markers. Further, 22,306 SNPs were identified by aligning high quality sequence reads of the three mango varieties to the reference unigene set, revealing significantly enhanced SNP heterozygosity in the hybrid Amrapali. The present study on leaf RNA sequencing of mango varieties and their hybrid provides useful genomic resource for genetic improvement of mango. PMID:27736892

    2015-01-01

    Full Text Available Background: Gingival recession is a common occurrence in periodontal disease leading to an unaesthetic appearance of the gingiva. The effect of platelet-rich fibrin (PRF, when used along with double lateral sliding bridge flap (DLSBF, remains unknown. The aim of this study is to evaluate the effect of PRF in conjunction with DLSBF for multiple gingival recessions. Materials and Methods: Twenty systemically healthy individuals exhibiting Grade II gingival recession on their mandibular central incisors were recruited in this study. These patients were randomly assigned into two groups: DLSBF and PRF + DLSBF. The clinical parameters that were evaluated in this study were gingiva recession height, gingiva recession width, width of keratinized gingiva, clinical attachment level, and probing depth. PRF was procured from the patient's blood at the time of the surgery and used for the procedure. The follow-up was performed at 12 and 24 weeks postsurgery. Results: Statistically significant difference was observed between the clinical parameters at baseline and 12 and 24 weeks within the groups. There was no statistically significant difference, between the groups. Mean root coverage (RC was 80% ±29.1% in the DLSBF group and 78.8% ±37.6% in the DLSBF + PRF group with no statistically significant difference. Conclusion: From the results obtained in this study, the addition of PRF to DLSBF gives no additional benefits to the clinical parameters measured in RC.

  5. Suppression of F1 Male-Specific Lethality in Caenorhabditis Hybrids by cbr-him-8.

    Haldane's Rule and Darwin's Corollary to Haldane's Rule are the observations that heterogametic F1 hybrids are frequently less fit than their homogametic siblings, and that asymmetric results are often obtained from reciprocal hybrid crosses. In Caenorhabditis, Haldane's Rule and Darwin's Corollary have been observed in several hybrid crosses, including crosses of Caenorhabditis briggsae and C. nigoni. Fertile F1 females are obtained from reciprocal crosses. However, F1 males obtained from C. nigoni mothers are sterile and F1 males obtained from C. briggsae die during embryogenesis. We have identified cbr-him-8 as a recessive maternal-effect suppressor of F1 hybrid male-specific lethality in this combination of species. This result implicates epigenetic meiotic silencing in the suppression of F1 male-specific lethality. It is also shown that F1 males bearing a C. briggsae X chromosome are fertile. When crossed to C. briggsae hermaphrodites or F1 females derived from C. briggsae hermaphrodites, viable F2 and backcross (B2) progeny were obtained. Sibling males that possessed a C. nigoni X chromosome were sterile. Therefore, the sterility of F1 males bearing a C. nigoni X chromosome must result from dysgenic interactions between the X chromosome of C. nigoni and the autosomes of C. briggsae. The fertility of F1 males bearing a C. briggsae X chromosome provides an opportunity to identify C. nigoni loci that prevent spermatogenesis, and hence hermaphroditic reproduction, in diplo-X hybrids.

    2014-01-01

    SiCSiC ceramic matrix composites (CMCs) systems will play a crucial role in next generation turbine engines for hot-section component applications because of their ability to significantly increase engine operating temperatures, reduce engine weight and cooling requirements. However, the environmental stability of Si-based ceramics in high pressure, high velocity turbine engine combustion environment is of major concern. The water vapor containing combustion gas leads to accelerated oxidation and corrosion of the SiC based ceramics due to the water vapor reactions with silica (SiO2) scales forming non-protective volatile hydroxide species, resulting in recession of the ceramic components. Although environmental barrier coatings are being developed to help protect the CMC components, there is a need to better understand the fundamental recession behavior of in more realistic cooled engine component environments.In this paper, we describe a comprehensive film cooled high pressure burner rig based testing approach, by using standardized film cooled SiCSiC disc test specimen configurations. The SiCSiC specimens were designed for implementing the burner rig testing in turbine engine relevant combustion environments, obtaining generic film cooled recession rate data under the combustion water vapor conditions, and helping developing the Computational Fluid Dynamics (CFD) film cooled models and performing model validation. Factors affecting the film cooled recession such as temperature, water vapor concentration, combustion gas velocity, and pressure are particularly investigated and modeled, and compared with impingement cooling only recession data in similar combustion flow environments. The experimental and modeling work will help predict the SiCSiC CMC recession behavior, and developing durable CMC systems in complex turbine engine operating conditions.

    2014-12-01

    The glaciers of the tropical Andes constitute 99% of the world's tropical glaciers. They primarily occur in Peru and Bolivia (90%) with smaller glaciers scattered across the peaks in Ecuador, Colombia, and Venezuela. Specific glaciers in the range have been studied in great detail, such as Bolivia's Zongo glacier and Peru's Quelccaya Ice Cap, but few studies of glacier recession across the full range have been published. We previously assessed glacier recession between c1987 and c2006 using manual classification techniques on Landsat imagery. We have now updated that study to the present (2013/2014), and and have incorporated automated techniques using support vector machines. The update to present allows us to examine both the variability in recession rates, and the current state of overall recession. The primary issues in completing this analysis are accounting for snow cover (which can otherwise be easily misidentified as glacier), and developing a robust and semi-automated methodology to process the large number of individual images required. To avoid confusion with transient snow, we analysed 2-3 clear images at each epoch, with minimal visually apparent snow or glacier, and only labelled as glacier those pixels that were classified as glacier in the clear portions of each image. To automate the processing, we used support vector machines, trained with the extensive data we have available from our previous manual classification work.Our previous work indicated an overall recession of approximately 30% (or 700 km2 of glacier area loss) between c1987 and c2006. We will present updated figures from our new analysis, extending to 2013/2014.

  11. Young entrepreneurs’ trust during the recession: Evidence from Serbia

    2015-01-01

    Full Text Available This paper deals with the influence of positive trust on business activities, entrepreneurship development, and economic growth. During the global recession, institutions make numerous decisions to find answers to the crisis that influence the behaviour of entrepreneurs. In such situations, significant stocks of trust are of great importance for economy stability and the motivation of future entrepreneurs. In the first section the terms, functions, and types of trust are defined. The second section presents the results of measuring the interpersonal and institutional trust of young entrepreneurs, representatives of future entrepreneurship and business and bearers of networking ideas in Serbia. The results show that young entrepreneurs have a serious trust deficit, which is worrying in people who are potential future business leaders. Only one fifth of the respondents intends to start their own firm when they have finished studying. The reasons most often given are that government economic policy and monopolies hamper starting a business. Most of the respondents thought that the government should be more involved in providing a better environment for medium and small business. Most respondents believed that the Serbian recession was caused foremost by wrong governmental economic policy, followed by corruption.

    Objective: The aim of this study was to evaluate the prevalence of 'high-riding' superior pericardial recess (HRSPR) on thin-section (1 mm) 16-multidetector computed tomography (MDCT) scans. Materials and methods: Three hundred and fourteen consecutive chest CT scans obtained with a thin-section 16 MDCT were retrospectively evaluated. The prevalence and characteristic of HRSPR were analyzed. Results: HRSPR was depicted in 21 patients (11 men and 10 women) (6.6%) who ranged in age from 28 to 72 years (mean age, 57 years). The extended recesses were rounded/oval shaped in five patients and triangular, spindle, half moon or irregular shaped in the other 16 patients. Conclusion: Our data suggest as HRSPRs are more frequently and better depicted on thinsection MDCT scans, and this improves the capability to distinguish this superior extension of the superior aortic recess from abnormal findings such as lymphadenopathy, cystic lesions, and aortic dissection.

    2010-12-01

    We report on the systematic retreat of all glaciers in the tropics of the New World from the mid-1980s to the mid-2000s. These glaciers comprise 99% of the world’s tropical glaciers and occur in Bolivia, Peru, Ecuador, Colombia, Venezuela, and Mexico. It was necessary to use a large quantity of Landsat satellite data (124 images), selecting multiple images for every glacier for both epochs, to minimize confusion of glacier area with snow. Change in glacier extent was combined with a digital elevation model (DEM) to provide information on the elevation and aspect of areas of glacier recession. Overall, we found glacier recession of approximately 30% over twenty years, declining from ~2500 km2 from the mid-1980s to ~1800 km2 in the mid-2000s. In addition, there was a strong association of glacier recession with elevation and aspect. We discuss these trends in relation to hypothesized climatic influences.

    This study examines the impact of the “Great Recession” as well as previous recessions in 1991 and 2001 on 8th and 10th graders in the U.S, using annual nationally representative data from the Monitoring the Future study. Historical changes in youth adjustment (self-esteem, depressed mood, risk taking, aggression, and property crime), school achievement (grade point average, time spent on homework, and educational expectations), and structured and unstructured activities (volunteering, employment, sports, and evenings out for fun) were examined between 1991 and 2014. Overall, there were only slight changes in mean levels of adjustment, achievement, and most youth activities. However, the percentage of youth working during the school year did decline during the Great Recession. Several longer term trends were also evident, though not directly tied to recessions. These include an increase in GPA, a decrease in time spent on homework, rising educational expectations, and more time spent volunteering. Future work should assess how the shift to unpaid work activities (e.g., volunteering and internships) among youth is impacting the transition from school to work in the contemporary economy, and whether the Great Recession had deleterious impacts for younger children or among youth whose parents lost work or had their homes foreclosed.

    Autosomal-recessive albinism is a hypopigmentation disorder with a broad phenotypic range. A substantial fraction of individuals with albinism remain genetically unresolved, and it has been hypothesized that more genes are to be identified. By using homozygosity mapping of an inbred Faroese family, we identified a 3.5 Mb homozygous region (10q22.2-q22.3) on chromosome 10. The region contains five protein-coding genes, and sequencing of one of these, C10orf11, revealed a nonsense mutation that segregated with the disease and showed a recessive inheritance pattern. Investigation of additional albinism-affected individuals from the Faroe Islands revealed that five out of eight unrelated affected persons had the nonsense mutation in C10orf11. Screening of a cohort of autosomal-recessive-albinism-affected individuals residing in Denmark showed a homozygous 1 bp duplication in C10orf11 in an individual originating from Lithuania. Immunohistochemistry showed localization of C10orf11 in melanoblasts and melanocytes in human fetal tissue, but no localization was seen in retinal pigment epithelial cells. Knockdown of the zebrafish (Danio rerio) homolog with the use of morpholinos resulted in substantially decreased pigmentation and a reduction of the apparent number of pigmented melanocytes. The morphant phenotype was rescued by wild-type C10orf11, but not by mutant C10orf11. In conclusion, we have identified a melanocyte-differentiation gene, C10orf11, which when mutated causes autosomal-recessive albinism in humans.

    The isolated gastrocnemius contracture present in neurologic healthy patients results in a significant limitation of ankle dorsiflexion causing pathologic gait patterns and a greater risk of further foot disorders. Gastrocnemius recession is an established procedure to increase ankle dorsiflexion....... However, little evidence is available of the use of gastrocnemius recession in these patients. Complication rates, recurrence of gastrocnemius contracture, and the prevalence of additional foot disorders needs further evaluation. A study group of 64 operated limbs undergoing gastrocnemius recession...... was evaluated to determine the prevalence of foot disorders, pre- and postoperative ankle dorsiflexion, and incidence of complications. A subgroup of 15 (23.4%) patients without additional operative procedures was examined regarding ankle dorsiflexion, strength (Janda method), sensitivity in the operated limb...

  17. Cost inefficiency under financial strain: a stochastic frontier analysis of hospitals in Washington State through the Great Recession.

    2017-06-01

    The importance of increasing cost efficiency for community hospitals in the United States has been underscored by the Great Recession and the ever-changing health care reimbursement environment. Previous studies have shown mixed evidence with regards to the relationship between linking hospitals' reimbursement to quality of care and cost efficiency. Moreover, current evidence suggests that not only inherently financially disadvantaged hospitals (e.g., safety-net providers), but also more financially stable providers, experienced declines to their financial viability throughout the recession. However, little is known about how hospital cost efficiency fared throughout the Great Recession. This study contributes to the literature by using stochastic frontier analysis to analyze cost inefficiency of Washington State hospitals between 2005 and 2012, with controls for patient burden of illness, hospital process of care quality, and hospital outcome quality. The quality measures included in this study function as central measures for the determination of recently implemented pay-for-performance programs. The average estimated level of hospital cost inefficiency before the Great Recession (10.4 %) was lower than it was during the Great Recession (13.5 %) and in its aftermath (14.1 %). Further, the estimated coefficients for summary process of care quality indexes for three health conditions (acute myocardial infarction, pneumonia, and heart failure) suggest that higher quality scores are associated with increased cost inefficiency.

  18. Male fertility in Greece: Trends and differentials by education level and employment status

    Full Text Available Background: More than downplayed, the role of men in the demographic analysis of reproduction has been entirely neglected. However, male fertility can be an important issue for exploring how economic and employment uncertainties relate to fertility and family dynamics. Objective: This paper intends to study fertility variations over time, relying solely on data referring to father's socio-demographic characteristics; in particular, their age, education level, and employment status. Methods: We use a combination of Labor Force Survey and Demographic Statistics data on population and Vital Statistics on births to estimate male fertility indicators and fertility differentials by education level and employment status, for the period 1992-2011 in Greece. In addition, over-time developments in male TFR are separated into structural (education-specific and employment-specific distributions and behavioral (fertility, per se changes. Results: We find that the male fertility level is declining, the fertility pattern is moving into higher ages, and the reproduction period for men is getting shorter. From 1992 up to 2008, changes in male fertility were mostly driven by behavioral rather than compositional factors. However, the decline of male fertility over the period of economic recession (2008-2011 is largely attributed to the continuous decrease in the proportions of employed men. Conclusions: The study suggests that male fertility merits further exploration. In particular, years of economic downturn and countries where household living standards are mostly associated with male employment, a father's employability is likely to emerge as an increasingly important factor of fertility outcomes.

    Interspecific F1 hybrid males of the Drosophila bipectinata species complex are sterile, while females are fertile, following Haldane's rule. A backcross scheme involving a single recessive visible marker on the X chromosome has been used to assess the putative roles of X-autosome and X-Y interactions in hybrid male sterility in the D. bipectinata species complex. The results suggest that X-Y interactions are playing the major role in hybrid male sterility in the crosses D. bipectinata x D. parabipectinata and D. bipectinata x D. pseudoananassae, while X-autosome interactions are largely involved in hybrid male sterility in the crosses D. malerkotliana x D. bipectinata and D. malerkotliana x D. parabipectinata. However, by using this single marker it is not possible to rule out the involvement of autosome-autosome interactions in hybrid male sterility. These findings also lend further support to the phylogenetic relationships among 4 species of the D. bipectinata complex.

  1. Segregation distortion causes large-scale differences between male and female genomes in hybrid ants.

    2010-04-20

    Hybridization in isolated populations can lead either to hybrid breakdown and extinction or in some cases to speciation. The basis of hybrid breakdown lies in genetic incompatibilities between diverged genomes. In social Hymenoptera, the consequences of hybridization can differ from those in other animals because of haplodiploidy and sociality. Selection pressures differ between sexes because males are haploid and females are diploid. Furthermore, sociality and group living may allow survival of hybrid genotypes. We show that hybridization in Formica ants has resulted in a stable situation in which the males form two highly divergent gene pools whereas all the females are hybrids. This causes an exceptional situation with large-scale differences between male and female genomes. The genotype differences indicate strong transmission ratio distortion depending on offspring sex, whereby the mother transmits some alleles exclusively to her daughters and other alleles exclusively to her sons. The genetic differences between the sexes and the apparent lack of multilocus hybrid genotypes in males can be explained by recessive incompatibilities which cause the elimination of hybrid males because of their haploid genome. Alternatively, differentiation between sexes could be created by prezygotic segregation into male-forming and female-forming gametes in diploid females. Differentiation between sexes is stable and maintained throughout generations. The present study shows a unique outcome of hybridization and demonstrates that hybridization has the potential of generating evolutionary novelties in animals.

    Full Text Available Background: One of the most common aesthetic problem encountered in the field of periodontology is gingival recession, which is, perceived by the patients as increase in length of teeth. The treatment of buccal gingival recession is a common requirement due to aesthetic concern or root sensitivity. This study was planned to evaluate the efficacy of PRF membrane compared to that of CTG in Miller's class I gingival recessions. Materials and Methods: 32 sites with Miller's Class I gingival recessions, out of which 16 sites received PRF (test and 16 sites received CTG (control. Each patient had undergone an initial periodontal treatment, including oral hygiene instructions, plaque control, and scaling and root planing, followed by re-evaluation. All clinical recordings; recession height, recession width, clinical attachment level, height of keratinized tissue, thickness of keratinized tissue, healing index and pain perception, were performed immediately before surgery (baseline and after 6 months interval following periodontal surgery. Results: In the test group, significant improvement was seen in terms CAL, REC-HT, REC-WD, HKT and TKT from baseline to 6 months. In the control group, only significant improvement seen was in REC-HT and TKT from baseline to 6 months. Comparison of both Healing Index and VAS score was done and it showed no significant difference between test and the control group except VAS at 1 week. Conclusion: Though CTG is a gold standard procedure, PRF can be used as an alternative procedure by keeping patient's comfort and recognition in mind.

    The impact of macroeconomic conditions on health has been extensively explored, as well as the relationship between individual unemployment and health. There are, however, few studies taking both aspects into account and even fewer studies looking at the relationship in a life course perspective. In this study the aim was to assess the role of macroeconomic conditions, such as national unemployment level, for the long-term relationship between individual unemployment and functional somatic symptoms (FSS), by analysing data from two longitudinal cohorts representing different periods of unemployment level in Sweden. A difference-in-difference (DiD) analysis was applied, looking at the difference over time between recession and pre-recession periods for unemployed youths (age 21 to 25) on FSS in adulthood. FSS was constructed as an index of ten self-reported items of somatic ill-health. Covariates for socioeconomics, previous health status and social environment were included. An association was found in the difference of adult FSS between unemployed and employed youths in the pre-recession and recession periods, remaining in the adjusted model for the pre-recession period. The DiD analysis between unemployed youths showed that men had significantly lower adult FSS during the recession compared to men in the pre-recession time. Adulthood FSS showed to be significantly lower among unemployed youths, in particular among men, during recession compared to pre-recession times. Since this is a fairly unexplored research field, more research is needed to explore the role of macroeconomic conditions for various health outcomes, long-term implications and gender differences.

    Historical events and personal experiences have the potential to alter the way people age. Using a life-course model, we examined how the Economic Recession of 2008 and experienced life events affected the mental health of 3,393 older adults in New Jersey. Data collected between 2006 and 2012 revealed a significant increase in mean depressive symptoms. Multinomial logistic regression analyses indicated that people with incident depression were more likely to have lost a job, become a caregiver, experienced a major illness, or have a family member with a major illness than people with no depression. Compared with the incident depression group, those with remitted depression were less likely to report having lost a job or experienced a major illness. Modeling the effects of individual life events and the economic recession on depression enriches understanding about the association between macro socioeconomic events, life events, and the mental health of older adults.

    Full Text Available The quality of working life depends on the extent to which aspects of the job enable employees to satisfy important psychological needs. In this paper we describe two studies exploring the quality of working life in Croatia during the economic crisis that started in 2008. Within the first study, independent samples of employees recruited by psychology students were asked to self-report quality of their jobs on four occasions between 2008 and 2010. In the second study, we tried to replicate the findings of Study 1, using employees drawn from nationally representative samples of citizens between 2008 and 2011. Results of both studies showed that the quality of working life in Croatia deteriorated during the recession. The decline was mainly related to extrinsic job aspects such as adequate pay, fair pay, and job security. The most hardly hit by the recession were lower educated employees.

    Full Text Available Background: Regular and daily physical activity during childhood and at school is one of the important part of requirements of normal growth, development and well-being. To achieve physical activity promotion among school child aged population recess as outside of class time efforts is scheduled and allows students to engage in physical and social activities. The purpose of the present study was to assess recess activities as well as status of physical activities among a sample of Iranian students at the pri¬mary schools.Methods: This cross-sectional study was performed in four randomly se¬lected schools from a list of 26 elementary schools in March, 2012 in the city of Shahindej, located in North-west of Iran. Participants were 439 (10–12 years elementary schools’. Physical activity level by self-reporting, mental health using the parent-completed Child Health Questionnaire, and happiness was assessed using a Persian translated version of the Subjective Happiness Scale. Hierarchical logistic regression analysis was applied in two steps using the enter method to analyze data in the SPSS version 17.Results: Backward logistic regression analysis showed that gender of the parent who answered the study questions, father’s education, educational grade of children, BMI, physical function, physical health, health status of the children and family function were significantly related to the children’s physical activity level.Conclusion: Promoting parents’ awareness and schools’ staff about im¬portance of physical activities especially in recess times must be an impor¬tant part of school and community mental health promotion programs.

    To develop an open, self-reported questionnaire, focused in understanding intake and intention to increase vegetable and fruit consumption during the Mexican children's lunchtime. After assessing pilot tests, the self-reported questionnaire was applied as a classroom exercise to measure children's consumptions of fruit and vegetables. A total of 486 children completed the questionnaire (49.8% males and 50.2% females). The reported food consumption indicates that 24.5% of children do not consume vegetables or fruits, and among consumers the most common portion size is one. Girls consume more vegetables and fruits and they can recognize more benefits. A total of 9.7% of the participants that do not consume VF, expressed less intention of including vegetables or fruits in their lunch. These results were similar to those reported by other authors. This study is useful to identify strengths and limitations during the design and implementation of this type of instrument to understand children's food habits during school recess.

    The object of this experiment was to test the radiosensitivity of the M/sub 1/ generation, and to determine the inheritance and morphological characteristics of the male-sterile mutants in tomatoes. The results obtained are as follows: Radiation damage varied with the water content of the seeds. The least damage occurred in the range of 11.34 to 14.29 percent moisture. Four tomato cultivars were gamma irradiated. The cultivar Sekai-ichi was the most sensitive while the other responded similarly to each other. Chemical mutagen treatments caused greater damage to germination, to delayed flowering and to pollen fertility than did radiation. Pollen fertility and seeds per fruit in seedling gamma irradiated plants decreased as the dosage and dose rate increased. Five male-sterile mutants were found. Each was controlled by a single recessive gene. All five male-steriles were nonallelic. Floral sized of the male-sterile mutants were slightly smaller. Ovule fertility varied, usually being lower than normal type. Male sterility varied, usually being lower than normal type. Male sterility in 109-1ms strain was caused by unbalanced, insufficient nutrients being made available to the pollen-mother cells from the tapetal tissued. (author).

    Little is known about the impact of recessions on young people's socioeconomic inequalities in health. This study investigates the impact of the economic recession in terms of youth unemployment on socioeconomic inequalities in psychological health complaints among adolescents across Europe and North America. Data from the WHO collaborative 'Health Behaviour in School-aged Children' (HBSC) study were collected in 2005/06 (N = 160,830) and 2009/10 (N = 166,590) in 31 European and North American countries. Logistic multilevel models were used to assess the contribution of youth unemployment in 2009/10 (enduring recession) and the change in youth unemployment (2005-2010) to adolescent psychological health complaints and socioeconomic inequalities in complaints in 2009/10. Youth unemployment during the recession is positively related to psychological health complaints, but not to inequalities in complaints. Changes in youth unemployment (2005-2010) were not associated with adolescents' psychological health complaints, whereas greater inequalities in complaints were found in countries with greater increases in youth unemployment. This study highlights the need to tackle the impact of increasing unemployment on adolescent health and health inequalities during economic recessions.

    We use longitudinal data from the Fragile Families and Child Well-being Study to investigate the impacts of the Great Recession on the health of mothers. We focus on a wide range of physical and mental health outcomes, as well as health behaviors. We find that increases in the unemployment rate decrease self-reported health status and increase smoking and drug use. We also find evidence of heterogeneous impacts. Disadvantaged mothers—African-American, Hispanic, less educated, and unmarried–experience greater deterioration in their health than advantaged mothers—those who are white, married, and college educated.

  16. Epistasis modifies the dominance of loci causing hybrid male sterility in the Drosophila pseudoobscura species group.

    Chang, Audrey S; Noor, Mohamed A F

    2010-01-01

    Speciation, the evolution of reproductive isolation between populations, serves as the driving force for generating biodiversity. Postzygotic barriers to gene flow, such as F(1) hybrid sterility and inviability, play important roles in the establishment and maintenance of biological species. F(1) hybrid incompatibilities in taxa that obey Haldane's rule, the observation that the heterogametic sex suffers greater hybrid fitness problems than the homogametic sex, are thought to often result from interactions between recessive-acting X-linked loci and dominant-acting autosomal loci. Because they play such prominent roles in producing hybrid incompatibilities, we examine the dominance and nature of epistasis between alleles derived from Drosophila persimilis that confer hybrid male sterility in the genetic background of its sister species, D. pseudoobscura bogotana. We show that epistasis elevates the apparent dominance of individually recessive-acting QTL such that they can contribute to F(1) hybrid sterility. These results have important implications for assumptions underlying theoretical models of hybrid incompatibilities and may offer a possible explanation for why, to date, identification of dominant-acting autosomal "speciation genes" has been challenging.

  1. The effect of a self-constructed material on children’s physical activity during recess

    Directory of Open Access Journals (Sweden)

    Antonio Méndez-Giménez

    Full Text Available ABSTRACT OBJECTIVE To analyze whether an intervention supported by free play with a self-constructed material increases the level of physical activity of students during recess. METHODS The participants were 166 children of third to sixth grade, between nine and 12 years old (average = 10.64; SS = 1.13. An experimental project was conducted with pre-test and post-test measurement, and a control group. Experimental group participants built cardboard paddles (third and fourth and flying rings (fifth and sixth, a material they used freely for one week during recess. ActiGraph-GT3X accelerometers were used to measure physical activity. An ANOVA of repeated measures was used to find differences between groups and genders. RESULTS Significant intervention effects were found in the analyzed variables: sedentary activity (F = 38.19; p < 0.01, light (F = 76.56; p < 0.01, moderate (F = 27.44; p < 0.01, vigorous (F = 61.55; p < 0.01, and moderate and vigorous (F = 68.76; p < 0.01. Significant gender differences were shown (time × group × gender for moderate (F = 6.58; p < 0.05 and vigorous (F = 5.51; p < 0.05 activity. CONCLUSIONS The self-constructed material is effective to increase the physical activity levels of children during recess; it decreases sedentary activity and light physical activity and increases the time devoted to moderate physical activity and vigorous physical activity, both in boys and in girls. The boys had an increase in vigorous physical activity and the girls in moderate physical activity. Due to its low cost, this strategy is recommended for administrators and teachers to increase the physical activity of children during recess.

    International Nuclear Information System (INIS)

    James, A.P.; Kilbey, B.J.

    1977-01-01

    The mechanism of uv-induced mutation in eukaryotes was studied in individual yeast cells by a procedure that combined pedigree analysis and tetrad analysis. The technique involved the induction of recessive lethals and semilethals in G1 diploid cells. Induced frequencies were 25 and 61% at survival levels of 90 and 77%, respectively. No evidence of gross chromosome aberrations was detected. Recessive mutations that affect only one strand or that affect both strands of the DNA molecule are induced much at random among a population of cells, and both types can occur within the same cell. However, the data confirm that two-strand mutations are in the majority after a low level of irradiation. The simplest explanation involves a mechanism whereby most mutations are fixed in both strands prior to the first round of post-irradiation DNA replication. The recessive mutational consequences of irradiation are exhausted at the conclusion of the first post-irradiation cell division, although dominant-lethal sectoring continues at a high level through the second post-irradiation division. It is concluded that pyrimidine dimers that persist to the second round of DNA replication are rare or ineffective

    2015-11-01

    The contemporary male look includes sharp contours of the face with strong nose, significant malar-midface structure, and a powerful chin with well-defined jawline. Neurotoxins in the upper facial lines should preserve a lower position of the brows and flatter arch in men. Excessive lifting of the eyebrows and full correction of forehead and periorbital lines are not desirable. The use of dermal fillers is fully accepted into the nasolabial. Male patients with sagginess and hollowness related or not related to acquired lipodystrophies are candidates for cheek correction with volumizers. Female attractiveness lies in the cheekbones, and for men, it lies in the chin. The use of volumizers in the chin is very much appreciated by male patients, especially when it is recessed. A strong and masculine appearance is obtained by creating a square chin. Men present slight thinner lips, especially the upper one. Lip reshape in male patients is very much rejected. It requires expertise both in communication and in technical skills to convince male patients to undergo lip treatments with fillers. The use of injectables in male patients is growing. Neurotoxins in the upper facial lines and the use of dermal fillers in the nasolabial folds are widely accepted. The use of volumizers in the chin is highly appreciated. There is clear need of volumizers in the cheek to correct sagginess and hollowness in men. However, proper communication and technique are required. The same applies for the lips. Cheek and lip reshape is still considered a taboo for most patients and injectors.

    2016-03-01

    Full Text Available Haldane’s Rule and Darwin’s Corollary to Haldane’s Rule are the observations that heterogametic F1 hybrids are frequently less fit than their homogametic siblings, and that asymmetric results are often obtained from reciprocal hybrid crosses. In Caenorhabditis, Haldane’s Rule and Darwin’s Corollary have been observed in several hybrid crosses, including crosses of Caenorhabditis briggsae and C. nigoni. Fertile F1 females are obtained from reciprocal crosses. However, F1 males obtained from C. nigoni mothers are sterile and F1 males obtained from C. briggsae die during embryogenesis. We have identified cbr-him-8 as a recessive maternal-effect suppressor of F1 hybrid male-specific lethality in this combination of species. This result implicates epigenetic meiotic silencing in the suppression of F1 male-specific lethality. It is also shown that F1 males bearing a C. briggsae X chromosome are fertile. When crossed to C. briggsae hermaphrodites or F1 females derived from C. briggsae hermaphrodites, viable F2 and backcross (B2 progeny were obtained. Sibling males that possessed a C. nigoni X chromosome were sterile. Therefore, the sterility of F1 males bearing a C. nigoni X chromosome must result from dysgenic interactions between the X chromosome of C. nigoni and the autosomes of C. briggsae. The fertility of F1 males bearing a C. briggsae X chromosome provides an opportunity to identify C. nigoni loci that prevent spermatogenesis, and hence hermaphroditic reproduction, in diplo-X hybrids.

  8. Assessing the short term health impact of the Great Recession in the European Union: a cross-country panel analysis.

    Toffolutti, Veronica; Suhrcke, Marc

    2014-07-01

    There are great concerns and some initial country-specific, descriptive evidence about potential adverse health consequences of the recent Great Recession. Using data for 23 European Union countries we examine the short-term impact of macroeconomic decline during the Great Recession on a range of health and health behaviour indicators. We also examine whether the effect differed between countries according to the level of social protection provided. Overall, during the recent recession, an increase of one percentage point in the standardised unemployment rate has been associated with a statistically significant decrease in the following mortality rates: all-cause-mortality (3.4%), cardiovascular diseases (3.7%), cirrhosis- and chronic liver disease-related mortality (9.2%), motor vehicle accident-related mortality (11.5%), parasitic infection-related mortality (4.1%), but an increase in the suicide rate (34.1%). In general, the effects were more marked in countries with lower levels of social protection, compared to those with higher levels. An increase in the unemployment rate during the Great Recession has had a beneficial health effect on average across EU countries, except for suicide mortality. Social protection expenditures appear to help countries "smooth" the health response to a recession, limiting health damage but also forgoing potential health gains that could otherwise result.

  9. Reducing friction in tilting-pad bearings by the use of enclosed recesses

    DEFF Research Database (Denmark)

    Heinrichson, Niels; Santos, Ilmar

    2008-01-01

    A three-dimensional thermoelastohydrodynamic model is applied to the analysis of tilting-pad bearings with spherical pivots and equipped with deep recesses in the high-pressure regions. A potential for a 10-20% reduction in the friction loss compared to conventional plain bearing pads is documented....... Design suggestions minimizing the power loss are given for various length-to-width ratios. The tilting angle in the sliding direction is more sensitive to correct positioning of the pivot point than conventional bearing pads. Improving the performance by equipping a tilting-pad bearing with a deep recess...... therefore requires accurate analysis and design of the bearing. Similarly, a high sensitivity perpendicular to the sliding direction suggests that this method of reducing friction is more feasible when using line pivots or spring beds than when using spherical pivots for controlling the tilting angle....

  10. Microcephaly-chorioretinopathy syndrome, autosomal recessive form. A case report

    Directory of Open Access Journals (Sweden)

    Rafael Fabiano Machado Rosa

    Full Text Available CONTEXT: The autosomal recessive form of microcephaly-chorioretinopathy syndrome is a rare genetic condition that is considered to be an important differential diagnosis with congenital toxoplasmosis.CASE REPORT: Our patient was a seven-year-old white boy who was initially diagnosed with congenital toxoplasmosis. However, his serological tests for congenital infections, including toxoplasmosis, were negative. He was the first child of young, healthy and consanguineous parents (fourth-degree relatives. The parents had normal head circumferences and intelligence. The patient presented microcephaly and specific abnormalities of the retina, with multiple diffuse oval areas of pigmentation and patches of chorioretinal atrophy associated with diffuse pigmentation of the fundus. Ophthalmological evaluations on the parents were normal. A computed tomography scan of the child's head showed slight dilation of lateral ventricles and basal cisterns without evidence of calcifications. We did not find any lymphedema in his hands and feet. He had postnatal growth retardation, severe mental retardation and cerebral palsy.CONCLUSIONS: The finding of chorioretinal lesions in a child with microcephaly should raise suspicions of the autosomal recessive form of microcephaly-chorioretinopathy syndrome, especially in cases with an atypical pattern of eye fundus and consanguinity. A specific diagnosis is essential for an appropriate clinical evaluation and for genetic counseling for the patients and their families.

    Microdeletions Glu767(1-bp del), Thr967(1-bp del), and Leu1446(2-bp del) in the human USH2A gene have been reported to cause Usher syndrome type II, a disorder characterized by retinitis pigmentosa (RP) and mild-to-severe hearing loss. Each of these three frameshift mutations is predicted to lead to an unstable mRNA transcript that, if translated, would result in a truncated protein lacking the carboxy terminus. Here, we report Cys759Phe, a novel missense mutation in this gene that changes an amino-acid residue within the fifth laminin-epidermal growth factor-like domain of the USH2A gene and that is associated with recessive RP without hearing loss. This single mutation was found in 4.5% of 224 patients with recessive RP, suggesting that USH2A could cause more cases of nonsyndromic recessive RP than does any other gene identified to date.

    A patient undergoing orthodontic treatment presented with multiple recession defects in maxillary anterior region. After thorough clinical examination and assessment, measurements were recorded. Maxillary anterior teeth with recession defects of 3-4 mm were treated with coronally advanced flap and platelet-rich fibrin (PRF) membrane. Regular follow-up was maintained for the patient at 3, 6 , 12, 18, 24, 30, and 36 months. After 36 months, significant root coverage of 100 percent was observed in four defects and 50% coverage in one defect. This shows that PRF membrane along with coronally advanced provides a predictable and significant result for management of recession defects.

    Full Text Available Although there is tremendous interest in understanding the evolutionary roles of horizontal gene transfer (HGT processes that occur during chronic polyclonal infections, to date there have been few studies that directly address this topic. We have characterized multiple HGT events that most likely occurred during polyclonal infection among nasopharyngeal strains of Streptococcus pneumoniae recovered from a child suffering from chronic upper respiratory and middle-ear infections. Whole genome sequencing and comparative genomics were performed on six isolates collected during symptomatic episodes over a period of seven months. From these comparisons we determined that five of the isolates were genetically highly similar and likely represented a dominant lineage. We analyzed all genic and allelic differences among all six isolates and found that all differences tended to occur within contiguous genomic blocks, suggestive of strain evolution by homologous recombination. From these analyses we identified three strains (two of which were recovered on two different occasions that appear to have been derived sequentially, one from the next, each by multiple recombination events. We also identified a fourth strain that contains many of the genomic segments that differentiate the three highly related strains from one another, and have hypothesized that this fourth strain may have served as a donor multiple times in the evolution of the dominant strain line. The variations among the parent, daughter, and grand-daughter recombinant strains collectively cover greater than seven percent of the genome and are grouped into 23 chromosomal clusters. While capturing in vivo HGT, these data support the distributed genome hypothesis and suggest that a single competence event in pneumococci can result in the replacement of DNA at multiple non-adjacent loci.

    To develop a help-wanted index (HWI) to measure trends in marketplace demand for ophthalmologists, to identify the economic drivers of demand, and to determine the impact of economic recessions on the ophthalmology job market. Review of physician recruitment advertisements appearing in the journals Ophthalmology, American Journal of Ophthalmology, and Archives of Ophthalmology from January 1980 through June 2006. Over the 26-year study period a consistent increase in the demand for subspecialists (31% of HWI in 1980 to 80% in 2005) was noted. There was also an increase in the demand for academic ophthalmologists. The need for academic ophthalmologists seems to be correlated with national research expenditure and stock market gains (P = .00191), whereas demand for private practice ophthalmologists seems to be correlated with the national economic well-being, as measured by gross domestic product (GDP) (P market gains, GDP, and discretionary health care expenditure have been associated with the ophthalmology job market. These factors tend to decline with economic recessions. Historically, the demand for ophthalmologists has declined 2 to 3 years following a recession, which may mean lower demand in the near future, given the recent recession.

Inclusion criteria comprised of English springer spaniel dogs with tachypnea and hyperthermia that subsequently developed weakness or collapse, with or without signs of hemorrhage, soon after a period of mild-to-moderate exercise. The pedigrees of the four affected dogs, as well as eleven related English springer spaniels, were then analyzed to determine a presumptive mode of genetic inheritance.Results: Four dogs met the inclusion criteria. All four were male, suggesting the possibility of a recessive sex-linked heritable disorder. Pedigree analysis suggests that more dogs may be potentially affected, although these dogs may have never had the concurrent triggering drug/activity/event to precipitate the clinical syndrome. There was complete resolution of clinical signs in three of the four dogs with aggressive symptomatic and supportive therapy, with one dog dying during treatment.Conclusion: Dogs with canine stress syndrome have the potential for rapid recovery if treated aggressively and the complications of the disease (eg, coagulopathy are anticipated. All four dogs were male, suggesting the possibility of a recessive sex-linked mode of inheritance. Further genetic analyses should be strongly considered by those

    Full Text Available Manar A Ghali Ophthalmology Department, Faculty of Medicine, Zagazig University, Zagazig, Egypt Purpose: To compare and evaluate the efficacy of two different surgical techniques for the treatment of near-distance disparity esotropia; combined resection–recession and recession–retroequatorial myopexy of medial rectus muscles. Patients and methods: This prospective study included 28 patients diagnosed with convergence excess esotropia who had worn their full cycloplegic refraction and/or bifocal glasses for at least 6 months and still had near-distance disparity esotropia. The patients were divided into 2 groups; Group I underwent combined bimedial rectus muscles resection 2.5 mm from the insertion end with recession based on near-angle esotropia according to current surgical tables with 1 mm add of recession for each muscle, while Group II underwent bimedial recession based on far angle combined with retroequatorial myopexy at 13–14 mm from insertion. A satisfactory result was defined as orthophoria or esotropia <10 prism diopters (∆ at near and distance with reduction of the near-distance disparity to <10 ∆. The patients were followed up for at least 2 years for stability of correction and late onset consecutive exotropia. Results: In Group I, all the patients had satisfactory alignments at near and far with residual near–far disparity ≤10 ∆, no cases of overcorrection at far was reported; while in Group II, all cases had orthophoria at far, but 4 cases (28.6% showed near–far disparity >10 ∆. Conclusion: The technique of combined resection–recession is safe, easy and more effective in the treatment of near-distance disparity esotropia regardless of the level of accommodative convergence/accommodation ratio, with stability of results though longer follow-up period is still needed.

    We report two approaches to fabricating high performance normally-off AIGaN/GaN high-electron mobility transistors (HEMTs). The fabrication techniques employed were based on recessed-metal-insulator-semiconductor (MIS) gate and recessed fluoride-based plasma treatment. They were selectively applied to the area under the gate electrode to deplete the two-dimensional electron gas (2-DEG) density. We found that the recessed gate structure was effective in shifting the threshold voltage by controlling the etching depth of gate region to reduce the AIGaN layer thickness to less than 8 nm. Likewise, the CF4 plasma treatment effectively incorporated negatively charged fluorine ions into the thin AIGaN barrier so that the threshold voltage shifted to higher positive values. In addition to the increased threshold voltage, experimental results showed a maximum drain current and a maximum transconductance of 315 mA/mm and 100 mS/mm, respectively, for the recessed-MIS gate HEMT, and 340 mA/mm and 330 mS/mm, respectively, for the fluoride-based plasma treated HEMT.

  20. On the use of spring baseflow recession for a more accurate parameterization of aquifer transit time distribution functions

    Directory of Open Access Journals (Sweden)

    J. Farlin

    2013-05-01

    Full Text Available Baseflow recession analysis and groundwater dating have up to now developed as two distinct branches of hydrogeology and have been used to solve entirely different problems. We show that by combining two classical models, namely the Boussinesq equation describing spring baseflow recession, and the exponential piston-flow model used in groundwater dating studies, the parameters describing the transit time distribution of an aquifer can be in some cases estimated to a far more accurate degree than with the latter alone. Under the assumption that the aquifer basis is sub-horizontal, the mean transit time of water in the saturated zone can be estimated from spring baseflow recession. This provides an independent estimate of groundwater transit time that can refine those obtained from tritium measurements. The approach is illustrated in a case study predicting atrazine concentration trend in a series of springs draining the fractured-rock aquifer known as the Luxembourg Sandstone. A transport model calibrated on tritium measurements alone predicted different times to trend reversal following the nationwide ban on atrazine in 2005 with different rates of decrease. For some of the springs, the actual time of trend reversal and the rate of change agreed extremely well with the model calibrated using both tritium measurements and the recession of spring discharge during the dry season. The agreement between predicted and observed values was however poorer for the springs displaying the most gentle recessions, possibly indicating a stronger influence of continuous groundwater recharge during the summer months.

    This study examined the associations of objectively measured physical activity in Physical Education and recess with academic performance in youth. This cross-sectional study was conducted with 1,780 participants aged 6 to 18 years (863 girls). Physical activity was objectively measured by accelerometry and was also classified according to sex- and agespecific quartiles of physical activity intensities. Academic performance was assessed through school records. Physical activity in physical education (PE) and recess was not associated with academic performance (β ranging from -0.038 to -0.003; all P > .05). Youth in the lowest quartile of physical activity in PE engaged in an average of 1.40 min of moderate-to-vigorous physical activity and those in the highest quartile engaged in 21.60 min (for recess: lowest quartile, 2.20 min; highest quartile, 11.15 min). There were no differences in academic performance between quartiles of physical activity in Physical Education and recess. Time spent at different physical activity intensities during PE and recess does not impair academic performance in youth.

    1978-04-01

    Legislation drafted in Switzerland in 1975--77 aims at countering the effects of inflation and recession by bringing increased revenues into the system, reducing expenditures, devising a mechanism to adjust pensions automatically, and improving income maintenance for the unemployed. The proposed legislation to place the social security system on a sound financial basis now needs voter approval in a referendum. Swiss voters meanwhile rejected (in mid-1977) a government-proposed value-added tax designed to finance increasing government contributions during 1978-82. Still to be resolved, therefore, is the problem of how the government will finance higher contributions and still achieve its staged goal of a balanced budget.

    Full Text Available In a previous study, we evaluated the findings related to the use of resorbable collagen membranes in humans along with DFDBA (demineralized freeze-dried bone allograft. The aim of this subsequent study was to histometrically evaluate in dogs, the healing response of gingival recessions treated with collagen membrane + DFDBA (Guided Tissue Regeneration, GTR compared to a coronally positioned flap (CPF. Two types of treatment were randomly carried out in a split-mouth study. Group 1 was considered as test (GTR: collagen membrane + DFDBA, whereas Group 2 stood for the control (only CPF. The dogs were given chemical bacterial plaque control with 0.2% chlorhexidine digluconate during a 90-day repair period. Afterwards, the animals were killed to obtain biopsies and histometric evaluation of the process of cementum and bone formation, epithelial migration and gingival level. A statistically significant difference was found between groups with a larger extension of neoformed cementum (GTR = 32.72%; CPF = 18.82%; p = 0.0004, new bone (GTR = 23.20%; CPF = 09.90%; p = 0.0401 and with a smaller area of residual gingival recession in the test group (GTR = 50.69%; CPF = 59.73%; p = 0.0055 compared to the control group. The only item assessed that showed no statistical difference was epithelial proliferation on the root surface, with means of 15.14% for the GTR group and 20.34% for the CPF group (p = 0.0890. Within the limits of this study we concluded that the treatment of gingival recession defects with GTR, associating collagen membrane with DFDBA, showed better outcomes in terms of a larger extension of neoformed cementum and bone, as well as in terms of a smaller proportion of residual recessions.

    Unhealthy persons are more likely to lose their jobs than those who are healthy but whether this is affected by recession is unclear. We asked how healthy and unhealthy persons fared in labour markets during Europe's 2008-2010 recessions and whether national differences in employment protection helped mitigate any relative disadvantage experienced by those in poor health. Two retrospective cohorts of persons employed at baseline were constructed from the European Statistics of Income and Living Conditions in 26 EU countries. The first comprised individuals followed between 2006 and 2008, n = 46,085 (pre-recession) and the second between 2008 and 2010, n = 85,786 (during recession). We used multi-level (individual- and country-fixed effects) logistic regression models to assess the relationship (overall and disaggregated by gender) between recessions, unemployment, and health status, as well as any modifying effect of OECD employment protection indices measuring the strength of policies against dismissal and redundancy. Those with chronic illnesses and health limitations were disproportionately affected by the recession, respectively with a 1.5- and 2.5-fold greater risk of unemployment than healthy people during 2008-2010. During severe recessions (>7% fall in GDP), employment protections did not mitigate the risk of job loss (OR = 1.06, 95% CI: 0.94-1.21). However, in countries experiencing milder recessions (recession, women with severe health limitations especially benefited, with additional reductions of 22% for each unit of employment protection (AORfemale = 0.78, 95% CI: 0.62-0.97), such that at high levels the difference in the risk of job loss between healthy and unhealthy women disappeared. Employment protection policies may counteract labour market inequalities between healthy and unhealthy people, but additional programmes are likely needed to protect vulnerable groups during severe recessions.

    Cole disease is a genodermatosis of pigmentation following a strict dominant mode of inheritance. In this study, we investigated eight patients affected with an overlapping genodermatosis after recessive inheritance. The patients presented with hypo- and hyperpigmented macules over the body, resembling dyschromatosis universalis hereditaria in addition to punctuate palmoplantar keratosis. By homozygosity mapping and whole-exome sequencing, a biallelic p.Cys120Arg mutation in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) was identified in all patients. We found that this mutation, like those causing dominant Cole disease, impairs homodimerization of the ENPP1 enzyme that is mediated by its two somatomedin-B-like domains. Histological analysis revealed structural and molecular changes in affected skin that were likely to originate from defective melanocytes because keratinocytes do not express ENPP1. Consistently, RNA-sequencing analysis of patient-derived primary melanocytes revealed alterations in melanocyte development and in pigmentation signaling pathways. We therefore conclude that germline ENPP1 cysteine-specific mutations, primarily affecting the melanocyte lineage, cause a clinical spectrum of dyschromatosis, in which the p.Cys120Arg allele represents a recessive and more severe form of Cole disease.

    Full Text Available Aim: Clarity on health expenditures is essential for the timely identification of risks that jeopardize the democratic provision of health services and the credibility of health insurance systems. Furthermore, observing health outcomes with geographical scope is essential for making multilateral associations. This study aimed at conveying information on the variability of important economic parameters of the health sector of Serbia and Greece from 2007 to 2012, when the most serious financial crisis in the post-war economic history hit the global economy. Methods: Exchange rates, purchase-power-parities (PPP and price indices were used for the bilateral review of health and pharmaceutical expenditure dynamics during 2007-2012. Prescription and dispensing changes were also studied taking into account the anatomical therapeutic chemical (ATC structure of drugs consumed. Results: Greece was forced to cut down its total health care and pharmaceutical expenditure and mainly its out-of-pocket payments were more seriously affected by the recession. Surprisingly, emerging market of Serbia, although severely damaged by global recession, succeeded to maintain 19% growth of its per capita health expenditure and even 25% increase of its per capita spending on pharmaceuticals. Innovative pharmaceuticals showed an upward trend in both countries. Conclusions: These two countries might serve as an example of two distinct pathways of mature and emerging health care markets during financial constraints caused by global recession. Our findings show that producing disease-based feedback, in the long run, may empower the assessment of the return on investment on medical technology and healthcare systems’ cost-effectiveness.

    Full Text Available Landscape changes of the Gåsbreen glacier and its vicinity since 1899 are described. Maps at 1:50 000 scale of changes of the glacier’s elevation and extent for the periods 1938–1961, 1961–1990, 1990–2010, and 1938–2010 are analyzed in comparison with results of the authors’ field work in the summer seasons 1983, 1984, 2000, 2005 and 2008. During all the 20th century, the progressive recession of the glacier revealed in a dramatic decrease in the thickness of its lower part, with a small reduction of its area and length. However, further shrinkage produced significant shortening and reduction in area which resulted in final decline of the Goësvatnet glacial dammed lake in 2002. Hence, the lowest (and very thick, up to 150–160 m part of the former glacier tongue and dammed lake were transformed into a new terraced river valley south of the glacier and a typical marginal zone with glacial landforms north of the glacier. Since 1961, the equilibrium line altitude of the Gåsbreen glacier has risen from ca 350 to ca 500 m a.s.l. and now is located below the very steep rocky walls of the Mehesten mountain ridge, 1378 m a.s.l. Hence, the glacier is being fed by snow avalanches from these rocky walls and much more snow melts during the warmer summer seasons, stimulating a quicker recession of the lowest part of the glacier. This recession may be stopped only by significant climate cooling or increase in snow.

    Effects of the Si 3 N 4 passivation on the dc and RF characteristics of a 0.1 µm metamorphic high-electron-mobility transistor (HEMT) are investigated for narrow and wide gate-recess structures. Maximum drain-source saturation current (I dss,max ) and maximum extrinsic transconductance (g m,max ) are reduced by ∼14.8 and ∼11.6%, respectively, in the wide gate-recess structure after the passivation; on the other hand, only ∼5.7 and ∼4.9% reductions are measured from I dss,max and g m,max , respectively, in the narrow gate-recess structure. We examine the passivation-induced degradation by using a modified charge control model assuming the charged surface states on the Si 3 N 4 interface and a comparative study of the hydrodynamic device simulation with the experimental measurement. From the analysis, it is proposed that the difference of degradation in two different gate structures is due to an approximately three times higher charged surface state density of ∼4.5 × 10 11 cm −2 in the wide gate-recess structure than ∼1.6 × 10 11 cm −2 in the narrow gate-recess structure. The cut-off frequency (f T ) of the wide gate-recess structure also exhibits a greater reduction of ∼14.5%, while the f T of the narrow gate-recess structure is reduced by only ∼6.6% after the passivation. This is mainly due to the passivation-induced surface states of a higher density in the wide gate-recess structure. A great increase of the gate-to-drain parasitic capacitance in the wide gate-recess structure makes a major contribution to ∼13.5% degradation of the maximum frequency of oscillation

This model also predicts excess returns in the right direction during expansions and recessions, whereas the Gaussian affine term structure model...

    Systemic banking crises often continue into recessions with large output losses (Reinhart & Rogoff 2009a). In this paper we ask whether the way Governments intervene in the financial sector has an impact on the economy's subsequent performance. Our theoretical analysis focuses on bank incentives to

    The frequency of parkin mutations was evaluated in 30 families of highly diverse geographic origin with early-onset autosomal recessive parkinsonism. Twelve different mutations, six of which were new, were found in 10 families from Europe and Brazil. Patients with parkin mutations had significantly

    Full Text Available Background: Gingival recession (GR can result in root sensitivity, esthetic concern to the patient, and predilection to root caries. The purpose of this randomized clinical study was to evaluate (1 the effect of guided tissue regeneration (GTR procedure using a bioabsorbable collagen membrane, in comparison to autogenous subepithelial connective tissue graft (SCTG for root coverage in localized gingival recession defects; and (2 the change in width of keratinized gingiva following these two procedures. Materials and Methods: A total of 10 cases, showing at least two localized Miller′s Class I or Class II gingival recession, participated in this study. In a split mouth design, the pairs of defects were randomly assigned for treatment with either SCTG (SCTG Group or GTR-based collagen membrane (GTRC Group. Both the grafts were covered with coronally advanced flap. Recession depth (RD, recession width (RW, width of keratinized gingiva (KG, probing depth (PD, relative attachment level (RAL, plaque index (PI, and gingival index (GI were recorded at baseline, 3 and 6 months postoperatively. Results: Six months following root coverage procedures, the mean root coverage was found to be 84.84% ± 16.81% and 84.0% ± 15.19% in SCTG Group and GTRC Group, respectively. The mean keratinized gingival width increase was 1.50 ± 0.70 mm and 2.30 ± 0.67 mm in the SCTG and GTRC group, respectively, which was not statistically significant. Conclusion: It may be concluded that resorbable collagen membrane can be a reliable alternative to autogenous connective tissue graft in the treatment of gingival recession.

  19. Health and the 2008 economic recession: evidence from the United Kingdom.

    Full Text Available The economic recession which began in 2008 has resulted in a substantial increase in unemployment across many countries, including the United Kingdom. Strong association between unemployment and poor health status among individuals is widely recognised. We investigated whether the prevalence of poor health at a population level increased concurrent to the rise in unemployment during the economic recession, and whether the impact on health varied by geographical and socioeconomic circumstances.Health, demographic and socioeconomic measures on 1.36 million survey responses aged 16-64 were extracted from the Quarterly Labour Force Survey of the United Kingdom, collected every three months, from January 2006 to December 2010. The likelihood of self-reporting poor health status and specific types of health problems (depression, mental illness, cardiovascular and respiratory across time were estimated separately using logistic regression. Explanatory variables included economic status (International Labour Organization definition, occupational class, age, gender, country of birth, ethnicity, educational qualifications, couple status, household tenure, number of dependents, and geographical region.Unemployment (age-gender adjusted rose from 4.5% in January 2008 to 7.1% by September 2009. The reporting of poor health status increased from 25.7% in July 2009 to 29.5% by December 2010. Similar increases were found for cardiovascular and respiratory health problems; not depression or mental illness. The prevalence of poor health status among the unemployed decreased from 28.8% in July 2008, to 24.9% by March 2009; but this was followed by an increase in poor health experienced across all regions and by all socioeconomic groups, including those who remained employed, regardless of their occupational class.Although our study found no exacerbation of pre-recession health inequalities, the rise in poor health status not only for the unemployed, but also among

    Full Text Available ABSTRACT This work aim to analyze the hydrodynamic process of oueme basin catchment basin located in Benin between 758N and 1012N latitude and 135 and 305E longitude. From rainfall and discharge data chronic rates over the period 2000-2009 empirical hydrological modeling based on linearization of Boussinesqs equation and least actions principle methods were used to predict the mechanism of the water drain to determine the streamflow recession curves to the watershed scale and compare the modeling findings with hygrogram obtained by applied of principle of the least actions. An analysis of drying up showed a varied trend in four sub-basins. At Beterou and Bonou sub-basin the non-linear character observed reflects a succession of phases of drying up. A conceptual linearization formulation of the basic equations of Boussinesq considering the non-linear character of the drying up of the two sub-basins helped simulate low flow rates with high efficiency and to determine the types low flow curves. Successfully comparing analyzed of modeling findings with recession curves obtained by least actions principle confirm the heterogeneity of recession nature at oueme basin scale.
