Assessing Biobehavioral Effects of Exposure to Traumatic Events in Palestinian Children

Background: A growing body of work suggests that exposure of children to the trauma of war threatens their physical and psychological development. Children exposed to such childhood adversity have an increased risk of developing mental health problems, including posttraumatic stress disorder (PTSD), emotional and behavioral problems, and psychobiological ailments. Methods: This pilot study used a descriptive cross-sectional design to explore the relationships among traumatic event exposure, child stress, and biological stress markers (salivary cortisol and salivary alpha-amylase) measured in a sample of 37 West Bank Palestinian children aged 10-12 years. Results: Findings revealed moderate correlations between perceived child stress scores and higher levels of traumatic exposure, higher awakening cortisol level, and greater variation in diurnal cortisol levels. Further, 32% of the sample demonstrated a reversed sAA diurnal pattern. Conclusion: In our study sample, children who reported higher exposure to violent traumatic events appeared to have higher perceived stress, and possibly were experiencing disruption in their normal physiologic stress response. With identification of more valid and reliable screening instruments, it may be possible to provide earlier identification of at-risk children, and direct interventions to help mitigate the impact of exposure to traumatic war events in this vulnerable population.

Maize gene expression UV response patterns reveal coordinate regulation of many genes

Understanding the mechanisms plants use for acclimation to ultraviolet radiation stress is key in predicting plant responses to our changing environment. Maize inbred line B73 plants were grown in sterilized vermiculite in a greenhouse under low fluence white light for 16 h/day until the majority of the plants were at the three-leaf stage. Plants were then subdivided into five groups of approximately 20 plants for treatments of one, two, four, eight, or twelve hours of UV-B irradiation at a dose rate of 0.024 W m-2. A sixth, control group was placed the same distance under an identical pair of UV bulbs that were covered with Mylar to block all UV-B radiation. Using transcripts from pools of leaf tissue, cDNA microarrays were used to monitor UV-induced alterations in gene expression to gain a better understanding of global gene expression in response to UV-B. Array data were standardized using a variance stabilizing procedure accounting for the many sources of systematic variation that affect measured gene expression levels. Examination of the effects after irradiation at different times indicated that the largest transcriptome response was evident after 12 hr of UV exposure followed by 8 hr, 2 hr, 1 hr, and 4 hr It was also determined that different suites of genes are expressed after specific UV treatments. Overall, it was determined that after 2 hr of UV exposure, rapid transcriptome responses occurred followed by a decrease in gene expression after 4 hr of UV exposure. After 8 hr of UV an increase in gene expression occurred that appeared to level off after 12 hr of UV exposure. With the analysis of gene expression over time, we have been able to identify new gene regulatory patterns in response to UV.

Tree species diversity and composition in urban green spaces of Allahabad city (U.P).

Existing plantation and gardens, as an important component of urban green infrastructure, could make significant contributions to urban biodiversity. This paper is an attempt to quantify the species composition, floristic diversity, amenity ecological characteristics, habitat condition, and performance of trees in urban areas of Allahabad, Central India. Assessments of green spaces in urban areas provide guidance for urban planners to maintain the adequate amount of greenery in cities for human wellbeing as well as to maintain the biodiversity. In this study a total of one hundred sixty five quadrates of dimension 20 m×20 m (6.6 ha) were laid to reveal tree diversity and richness of UGSs. Total 1464 stems belonging to 64 species of 60 genera and 28 families with > 10 cm girths at breast height (gbh) were inventoried. Fabaceae is the largest family with 13 species followed by Moraceae (6), Malvaceae (5); Myrtaceae, Rutaceae, Meliaceae (4) each; and Sapotaceae, Arecaceae (3) each. Allahabad’s urban forest has a fairly un-healthy diversity, about 13.25% of total tree density occupied by most abundant species P. longifolia. Other five top most species include P. longifolia, P.guajava, M.indica, W. bifurcata and P. pterocarpum contributed about 34.76% to total tree density.

BDL.NET: Bayesian dictionary learning in Infer.NET

We introduce and analyse a flexible and efficient implementation of Bayesian dictionary learning for sparse coding. By placing Gaussian-inverse-Gamma hierarchical priors on the coefficients, the model can automatically determine the required sparsity level for good reconstructions, whilst also automatically learning the noise level in the data, obviating the need for heuristic methods for choosing sparsity levels. This model can be solved efficiently using Variational Message Passing (VMP), which we have implemented in the Infer.NET framework for probabilistic programming and inference. We analyse the properties of the model via empirical validation on several accelerometer datasets. We provide source code to replicate all of the experiments in this paper.
Mitochondrial inheritance and germ line determination in a bivalve species with Doubly Uniparental Inheritance (DUI)

Mitochondria are inherited maternally in most metazoans. However, in some bivalves, two mitochondrial lineages are present: one transmitted through eggs (F), the other through sperm (M). This is called Doubly Uniparental Inheritance (DUI). During male embryo development, spermatozoon mitochondria aggregate and end up in the primordial germ cells, while they are dispersed in female embryos. The molecular mechanisms of segregation patterns are still unknown. In the DUI species Ruditapes philippinarum, I examined sperm mitochondria distribution by MitoTracker, microtubule staining and TEM, and I localized germ line determinants with immunocytochemical analysis. I also analyzed the gonad transcriptome, searching for genes involved in reproduction and sex determination. Moreover, I analyzed an M-type specific open reading frame that could be responsible for maintenance/degradation of M mitochondria during embryo development. These transcripts were also localized in tissues using in situ hybridization. As in Mytilus, two distribution patterns of M mitochondria were detected in R. philippinarum, supporting that they are related to DUI. Moreover, the first division midbody concurs in positioning aggregated M mitochondria on the animal-vegetal axis of the male embryo: in organisms with spiral segmentation this zone is not involved in further cleavages, so aggregation is maintained. Moreover, sperm mitochondria reach the same embryonic area where germ plasm is transferred, suggesting their contribution in male germ line formation. The finding of reproduction and ubiquitination transcripts led to formulate a model in which ubiquitination genes stored in female oocytes during gametogenesis would activate sex-gene expression in the early embryonic developmental stages (preformation). Only gametogenetic cells were labeled by in situ hybridization, proving their specific transcription in developing gametes. Other than having a role in sex determination, some ubiquination factors could also be involved in mitochondrial inheritance, and their differential expression could be responsible for the different fate of sperm mitochondria in the two sexes.
The Role of Sp1 and Sp3 Transcription Factors in Hematopoiesis

textabstractHematopoiesis is the generation of all mature blood cells from a rare pool of hematopoietic stem cells (HSCs). These blood cells serve a variety of essential functions in the vertebrate body, including gas transport, defense against pathogens, blood clotting and removal of apoptotic cells. Due to their limited life span, they need to be generated continuously throughout life in the stem cell niches of the bone marrow and several discrete anatomical niches that change rapidly, accompanying the highly dynamic processes characteristic of embryonic development. Multi-potent hematopoietic stem cells give rise to a succession of progenitors from which mature blood cells are derived. The hematopoietic system is made up of all mature blood cell types including erythrocytes, platelets, and other cells of the myeloid and lymphoid lineages. Multiple waves of hematopoiesis occur during embryonic development. The initial wave of blood production, termed primitive hematopoiesis, occurs in the mammalian yolk sac followed by definitive hematopoiesis originating from long term-hematopoietic stem cells that arise from the aorta-gonad-mesonephros (AGM) origin.

Phylogeny and biogeography of the toxic dinoflagellate Alexandrium

Abstract : The incidence and known distribution of paralytic shellfish poison-producing Alexandrium dinoflagellates have both increased dramatically in recent decades. This thesis explores the phylogeny, taxonomy, and biogeography of Alexandrium in light of this expansion. Alexandrium rDNA sequence phylogeny did not correlate with morphological traits traditionally used to identify and group species. The morphospecies of the tamarensis complex, A. catenella, A. tamarense, and A. fundyense, did not represent valid species by the phylogenetic, biologic, or morphological species concepts. Instead, five cryptic species were identified through phylogeny and mating incompatibility: A. universa, A. toxipotens, A. mediterra, A. tamarensis, and A. tasmanense. Within the minutum group, A. lusitanicum and A. angustitabulatum were not distinct species based on morphology and phylogeny while A. insuetum and A. tamutum were clearly distinct and three new species were identified. The ability to produce toxins has been acquired and/or lost multiple times during Alexandrium evolution. Each species of the tamarensis complex appears to contain either all toxic or non-toxic isolates, while toxic and non-toxic A. minutum strains cannot be segregated based upon LSU sequences. The reconstructed biogeography of the tamarensis and minutum complexes indicate that both natural dispersal and human-assisted transportation of Alexandrium have caused the geographic spread.

The Effect of Training and Career Development on Employees Retention –A Study on the Telecommunication Organizations in Yemen

Employees retention represents one of the main keys to organizational productivity, performance, competitive advantage and success. Therefore, organizations look for ways to improve their employees’ satisfaction and retention. Organizations worldwide have been realizing the importance of this issue. However, many organizations specifically in Arabic context still failing in retaining their employees, especially the most talented and qualified ones. Although many studies have been done to investigate the effect of human resources practices on employees’ satisfaction and retention, many of these studies show the impact of the monetary part of it such as compensation. The purpose of this paper is to investigate effects of non-monetary practices, training and career development on employees’ retention in organizations within the telecommunication sector in Yemen. Moreover, current study seeks to investigate the mediating role of that job satisfaction in the training, career development, and employees’ retention relationship. Using a sample of 100 non-managerial employees in the four Yemeni telecommunication organizations, results indicated that training has a positive impact on the employees’ satisfaction and retention. In fact, results show the importance of training in enhancing employees’ satisfaction as well as improving their retention rate in the telecommunication sector in Yemen. Surprisingly, results showed that career development has no relationship with employees’ satisfaction or retention. Results also found that Job satisfaction mediates the relationship between training and employees’ retention in the Yemeni telecommunication sector.

Structure-function relationships in a glycosyltransferase, a phosphatase and an oxidoreductase

ion from the hydroxyl by hydrogen bonding to Lys230*. Conversion of isocitrate into oxalosuccinate is fast (37) and, except for the observed ~90o rotation of the C1-carboxylate upon the change in hybridization at C2 from sp to sp, need be accompanied only by minimal structural rearrangements in the active site pocket. Next, decarboxylation of oxalosuccinate produces an enol intermediate, with the C2 carbonyl re-protonated by Lys230*. Loss of CO2 allows an invariant Tyr (Tyr160 in EcoIDH) to approach C3 for stereospecific protonation, while Lys230* once again abstracts the proton from the C2 hydroxyl to yield the ketoglutarate product. In the K100M [Mg:ICT:NADP] x2 ternary product complex, Lys230* hydrogen bonds to the C2 carbonyl while Tyr160 seems poised to (de)protonate C3, albeit 3.4 Å away. Indeed, the near planar ketoglutarate suggests some double-bond character between C2 and C3 (reducing the C1-C2-C3-C4 dihedral angle from 20° to 0° does not greatly compromise the observed electron density). Alternatively, the electron density may represent -hydroxyglutarate (and NADP). In the absence of CO2, IDH uses NADPH to reduce -ketoglutarate to -hydroxyglutarate, and NMR studies have detected the signature of -hydroxyglutarate bound to pig heart IDH (12). Thus, the observed electron density is probably an average dominated by the carbonyl form of -ketoglutarate with lesser contributions from the enol form and -hydroxyglutarate.
The low temperature microflora of young cheddar cheese

Summary A plating procedure simulating conditions in ripening Cheddar cheese was used to isolate microorganisms in young cheese that grow at ordinary ripening temperatures. Forty-one commercial cheese samples, most 7 days old, were obtained from ten Iowa manufacturing plants. Samples were plated in special Trypticase-soy agar, covered with 50 ml of 1.5% (w/v) agar, and incubated at 7.2 C for 3 months. Following incubation, 967 microorganisms were isolated, purified, and characterized. Numbers and percentages of microorganisms were: 475 enterococci, 49.5%; 148 micrococci, 15%; 126 lactic streptococci, 13%, 108 miscellancous gram-positive rods, 11%; 48 associate bacteria (resembling species of Leuconostoc), 5%; 33 miscellaneous gram-negative rods, 3.5%; 24 lactobacilli, 2.5%; and 5 other miscellaneous microorganisms, 0.5%. Forty-five commercial lactic starter cultures were examined by the same plating procedure. Duplicate plates of each culture were incubated at 7.2 and 21 C. Although agar plate counts were.
Identification of expressed genes in early maturated fruit of pequi (Caryocar brasiliense Cambess.)

The pequi (Caryocar brasiliense Cambess.) is a species native to the Brazilian Cerrado and plays an important social and nutritional role for the population of the region. It is a species that is traditionally gathered and today is seen as a source for the production of biodiesel. The objective of this study was to identify sequences from a cDNA library that are involved in the metabolic pathways in early maturated fruit stage of pequi. To do so, a cDNA library was created and the clones were cloned and sequenced. These identified sequences were deposited in GenBank. Most of the sequences found using the Blastn and tBlastx tools are associated with protection against oxidative stress in plants, some are transcription factors and others provide structural and pathogenic resistance. The transcriptome of pequi is an effective method of identifying genes and proteins responsible for important biological characteristics of the plant, thus laying the groundwork for new studies aimed at developing a full understanding of the genomic structure of the pequi.

Successful Treatment of Propafenone Intoxication with Intravenous Lipid Emulsion and Review of the Literature

©Copyright 2017 by Turkish Society of Medical and Surgical Intensive Care Medicine Available online at www. dcyogunbakim.org Informed Consent: We could not obtain informed consent because of the patient’s hospital record information is inaccurate. Peer-review: Externally peer-reviewed. Abstract Propafenone is Class Ic antiarrhythmic medication widely used for treating arrhythmias. Propafenone is commonly used for treating atrial fibrillation in patients with no structural heart disease. Intake of an excessive amount of propafenone can lead to cardiotoxic symptoms, such as hypotension, arrhythmias, and death. We report on the case of a 22-year-old female presenting to the Dumlupınar University Evliya Çelebi Training and Research Hospital emergency department after trying to commit suicide by ingesting 6750 mg of propafenon.

Intron Length Variation Observed in the Creatine Kinase and Ribosomal Protein Genes of the Swordfish Xiphias gladius.

Introns may accumulate much higher genetic variation than exons. Universal primers were designed from the conservative nucleotide sequences of exons to amplify the flanking intron. Length variations in the S7 ribosomal protein (RP) gene intron I and mitochondrial creatine kinase (CK) gene intron 6 of the swordfish Xiphias gladius were found. Single or two banded fragment patterns in each in dividual were observed by agarose gel electrophoresis. Nucleotide sequence analysis revealed that high ly polymorphic fragment patterns observed in the RP gene intron 1 were due to different numbers of a TG repeat (microsatellite). The length of the CK gene intron 6 was dimorphic, in which presence or ab sence of a 24 by block was responsible for longer or shorter introns. Additional minor nucleotide inser tion/deletions were observed independent of the RP microsatellite and the CK 24 by block regions. The results of this investigation indicate that introns may be good sources of intraspecific genetic variation for population genetic studies and that the same set of primers can be used to amplify homologous in tron regions even among distant species. Further, the conserved exon primed PCR strategy may be use ful to prevent appearance of priming site polymorphism (null allele).
Comparison of Quantitative Real-Time PCR and Short Tandem Repeat PCR for Monitoring Chimerism after Hematopoietic Stem Cell Transplantation in Paediatric Patients

Post-hematopoietic stem cell transplantation chimerism monitoring is important to assess the kinetics of engraftment, and to assist in diagnosis of graft failure, rejection or relapse. The purpose of this study aimed to compare two methods, short tandem repeat polymerase chain reaction (STR-PCR) and quantitative real-time PCR (qRT-PCR), in order to determine hematopoietic chimerism. The chimerism of blood samples from 57 paediatric patients were analyzed by STR-PCR and qRT-PCR on different days after allogeneic hematopoietics stem cell transplantation. The results showed good quantitative correlation between the two methods with correlation coefficient (r)=0.854 (p<0.001). The high correlation between STR-PCR and qRT-PCR methods helps to validate the use of qRT-PCR for chimerism analysis. The chimerism status may differ using the different methods. In some samples, the chimerism status using the STR-PCR showed complete donor chimerism however it showed mixed chimerism using qRT-PCR. On the other hand, all samples with complete donor chimerism in qRT-PCR were also in complete donor chimerism using STR-PCR. Thus, qRT-PCR is a valid, more sensitive, simple and rapid compared to STR-PCR method in chimerism monitoring.
