Effect of Spinal Versus General Anesthesia on Pulmonary Functions among Adults at Al-Sadder Medical City: Comparative Study

Objective: The study aims to detect the effect of spinal versus general anesthesia on pulmonary function and find out the relationships between patients pulmonary functions post- surgery and their demographic and clinical characteristics.Methodology: A comparative study design carried out through the present study in order to achieve the early stated aims. The study started in 21 December 2015 to 30 April 2016 The study conducted in Al-Sadder medical city. Quota sample of (100) patients were included in the present study, (50) patients received general anesthesia and (50) patients received spinal anesthesia. The patients demographic and clinical data collected through the utilization the semi-structured questionnaire and by means of interview technique with the subject, while the pulmonary functions test collected by using spirometer instrument. Data was analyzed by using descriptive statistic (percentage and Frequencies) and inferential (person s correlation coefficient, independent sample t-test, and paired t-test). Results: shows that higher of patient are within the age interval about 39-47 years old %),equal ratio of gender are male (50%)and female, there are highly significant of body mass index is normal (70%), most of patient are non-smoker (47%), most of patient non-worker is, high ratio of operation in the lower of body, all of patient without respiratory disorder, more the patient without chronic disease, The study results indicate that there is a significant effect of the anesthesia on the patients pulmonary functions test and the general anesthesia is negatively affect the pulmonary functions more than the spinal anesthesia. In addition, that there is a high significant relationship between the pulmonary functions pre and post general anesthesia and high significant relation between the pulmonary functions pre and post spinal anesthesia and high significant relation between the pulmonary functions post-anesthesia and the types of anesthesia.Conclusions: The study concluded that anesthesia has effect on pulmonary function. Recommendations: The study recommended that breathing techniques should use for patients before anesthesia and smoking cessation before 4-8 weeks of surgery Studies should evaluate the clinical effects of different anesthesia regimes in patients with compromised lung function, and Reduction in FVC after surgery should influence the clinician decision at this time when choosing between general and spinal anesthesia depends on the particular clinical situation, possible other disorders, and the surgical demands.
The Association of Elevated Serum IgE and Xerostomia with Recurrent Aphthous Stomatitis

Background and objectives: Recurrent Aphthous Stomatitis (RAS) is one of the most common oral mucosal diseases. This study aimed to determine the prevalence of RAS, the association of Immunoglobulin E with RAS and potential risk factors of RAS in patients at dental clinics of Sana’a universities in Sana’a city, Yemen. Subjects and methods: A cross-sectional study was conducted from January to December 2017 and includes 2164 patients. The patients interviewed and examined by dentists and 72 were clinically diagnosed to have RAS. The patients with RAS responded to a questionnaire that included demographic background, Qat chewing habits, smoking habits, history and course of RAS episodes. They were also subjected to laboratory tests, including determination of serum IgE levels and xerostomia. Results: The crude prevalence of RAS was 3.3%; female prevalence was 3.8% slightly higher than 2.4% of the male. There was a higher rate of RAS in age group 16-25 years (12.3%) and age group 26-35 years (9.3%) with OR=7 times and 4.1 times respectively (p<0.001). While lower rates of RAS were occurred in children under 15 years (0.41%) and older age (0.4%), (<0.001). The Mean±SD of IgE level for major RAS patients was 233±15.3IU/ml; while for minor was 127±17.3IU/ml. There was association between elevated IgE, Xerostomia, smoking habit, and chewing Qat and occurrence of major RAS (OR=6.4, 3.3, 26.8, and 7.1 respectively). Conclusion: Elevated IgE levels and xerostomia may be considered as part of the RAS patient’s work-up. Further research is needed to identify biological mechanisms that account for the observed associations.
Plant SYP12 syntaxins mediate an evolutionarily conserved general immunity to filamentous pathogens

Filamentous fungal and oomycete plant pathogens that invade by direct penetration through the leaf epidermal cell wall, cause devastating plant diseases. Towards non-adapted filamentous pathogens, plant pre-invasive immunity is highly effective and durable. Pre- and post-invasive immunity correlates with the formation of evolutionarily conserved and cell-autonomous cell wall structures, named papillae and encasements. Yet, it is still unresolved how papillae/encasements are formed and whether these defense structures prevent pathogen ingress. Here we show that in Arabidopsis, the two closely related members of the SYP12 clade of syntaxins (PEN1 and SYP122) are indispensable for the formation of papillae and encasements. Moreover, loss-of-function mutants were hampered in pre-invasive immunity towards a range of taxonomically distinct non-adapted filamentous pathogens, underlining the versatility and efficacy of this defense. Complementation studies using SYP12s from the early diverging land plant, Marchantia polymorpha, showed that the SYP12 clade immunity function has survived 470 My of independent evolution. These results suggest that ancestral land plants evolved the SYP12 clade to provide a broad and durable pre-invasive immunity to facilitate their life on land, and pave the way to a better understanding of how adapted pathogens overcome this ubiquitous plant defense strategy.
Meningeal Gadolinium Enhancement in Low‐pressure Headaches

Three patients with headaches in erect but not recumbent positions had barely measurable cerebrospinal fluid (CSF) pressures and aseptic but abnormal CSF findings with variable pleocytosis and elevated protein content. The CSF glucose level was normal and there were no blasts or malignant cells. Gadolinium‐enhanced magnetic resonance imaging (MRI) in all 3 showed diffuse meningeal enhancement. In 2, headaches and MRI abnormalities completely resolved spontaneously. The third patient, who had a prior ventriculoperitoneal shunt, improved after shunt revision.
A study on clinico-histopathological patterns of ovarian tumors

Background: Ovarian tumors are an increasing cause for morbidity and mortality world over. The objective of this study was to study the distribution of ovarian tumors histopathologically in different age groups and their various clinical presentations. Methods: Ninety eight patients who presented with 140 ovarian lesions on either or both sides were analyzed during a study period of one year and a further one year follow-up of patients with malignant tumors were done in a Tertiary teaching hospital. Results: There were 140 lesions comprising of 40% of neoplastic lesions and 60% of non-neoplastic lesions. Among the ovarian neoplasms, 91.1% were benign lesions, 7.1% malignant and 1.8% were borderline malignant. Serous tumors were the commonest tumors (46.4%) followed by mucinous tumors and germ cell tumors (23.2% each). Endometriotic cysts (34.5%) were the commonest non-neoplastic lesions. The distribution of benign tumors in the reproductive age groups was only slightly more than that in the perimenopausal age group. All malignant tumors were in the perimenopausal age group. Menstrual complaints like irregular bleeding and menorrhagia formed the majority of clinical presentation. Bilaterality of lesions was seen in 16 patients. Conclusions: Benign ovarian tumors are common in reproductive age group as well as perimenopausal age group. The most common neoplasm present was surface epithelial tumors - serous tumors followed by germ cell and mucinous tumors. The most common non-neoplastic lesions were endometriotic cysts and inclusion cysts. Bilateral involvement was uncommon with preponderance of lesions on the right side. Common clinical presentations were menstrual problems and abdominal pain.
DOES ENTREPRENEURSHIP EDUCATION HAVE IMPACT ON OPENING AND MAINTAINING A GARMENT BUSINESS STRATEGY?

This article aims to analyse the extent of the role of Business Education in upgrading to improve and enhance clothing convection businesses. This article uses descriptive qualitative methods. There were eight sampling participants in the study, including owners and participants of clothing convection businesses. Data analysis was carried out through observation, documentation, and in-depth interviews with participants. The results showed that Business Education did not significantly affect businessmen to open a garment business. The work environment and experience including the educational background of the owners, which varied from elementary school graduate to undergraduate, influenced them to open a garment business Businessmen open garment business because they follow trends, family offspring, continuing friends’ businesses, and their great passion. In the strategy of maintaining a garment business, businessmen need Business Education. It is proven by the fact that these owners often participate in screen printing and sewing seminar workshops, read business books, and get business education through field discussions.
Maximal estimates for the Fokker–Planck operator with magnetic field

We consider the Fokker-Planck operator with a strong external magnetic field. We show a maximal type estimate on this operator using a nilpotent approach on vector field polynomial operators and including the notion of representation of a Lie algebra. This estimate makes it possible to give an optimal characterization of the domain of the closure of the considered operator.
Ageing Tests at Constant Currents and Associated Modeling of High Temperature PEMFC MEAs

In this work, seven commercially available high temperature (HT) membrane electrode assemblies (MEAs), using a phosphoric acid doped polybenzimidazole (PBI) membrane, were tested at six constant current densities during mostly around 540 h: 1, 0.6, 0.4, 0.2, 0.1, and 0 A cm−2. The MEA aged at 0.6 A cm−2 appears to be the less degraded one and the MEAs working at 0 and 1 A cm−2 seem to be the most degrading ones. Degradations are supposed to be mainly due to the carbon corrosion of electrodes and the loss of electrolyte with the MEA aged at 1 A cm−2. The characterization periods have a significant impact on cell ageing. The corrosion of carbon support is considered here to be the major degradation for the tests carried out between 0 and 0.6 A cm−2. A degradation rate was calculated using the voltage from the polarization curves and it appears to be more relevant compare to the degradation rate calculated using the voltage during endurance period. The modeling approach shows promising results and it seems that the electrochemical surface area, measured by cyclic voltammetry, can be included into the modeling in order to obtain higher parameter consistency.
MEDIATING ROLE OF PERSON-ORGANIZATION FIT IN PERSON-JOB FIT'S EFFECT ON JOB SATISFACTION

The aim of this study is to investigate how person-job fit affects person-organization fit and job satisfaction and whether person-organization fit has a mediating role in this process. For this purpose, data were collected from 282 participants working in banks. Confirmatory factor analysis was performed in the analysis of the data, correlations between the variables were determined, and the structural equation and goodness of fit tests of the model and regression analysis were performed. In the analyses, it was determined that person-job fit had a significant positive effect on person-organization fit and job satisfaction. Person-organization fit was found to have a significant positive effect on job satisfaction. As a result of mediating analysis, person-organization fit found to have a partial mediator role in the relationship between person-job fit and job satisfaction.
The Sensitivity of Trading to the Cost of Information

This study examines the impact of changes in data feed pricing schedules on the price discovery between competing venues, as espoused by Cespa & Foucault (2014). We utilize three exogenous events stemming from a staggered increase in the data feed price that transpired on the Chicago Mercantile Exchange and observe a decrease in the efficiency of price discovery following increases in the acquisition costs of exchange’s data feeds, in line with the theory. Our results indicate that the regulators need to closely monitor any increases in data fees since these not only redistribute income from the traders to the exchanges but also affect the quality of the market via price discovery, one of the market’s most important functions.

Dialogic Tensions in Pre-Service Subject Teachers’ Identity Negotiations

ABSTRACT This study explores how five pre-service subject teachers from different disciplines made sense of and characterized their teacher identity after completing their yearlong pedagogical studies. Leaning on the Bakhtinian dialogical approach and socio-culturally oriented discourse analysis, we examine how the students negotiated multiple voices in their narratives (interviews) and how they positioned themselves in relation to these voices. In the students’ identity negotiation, the Discourse based on participatory pedagogy and education responsibility contradicted with the Discourse of traditional pedagogy that the students had as a cultural resource from their own youth. These different Discourses collided with each other and were tested and reflected in an internal dialogue. Through this process, the students negotiated their prospective subject teacher identity.

Bacterial lipopolysaccharide induces settlement and metamorphosis in a marine larva

How larvae of the many phyla of marine invertebrates find places appropriate for settlement, metamorphosis, growth and reproduction is an enduring question in marine science. Biofilm induced metamorphosis has been observed in marine invertebrate larvae from nearly every major marine phylum. Despite the widespread nature of this phenomenon the mechanism of induction remains poorly understood. The serpulid polychaete Hydroides elegans is a well-established model for investigating bacteria-induced larval development. A broad range of biofilm bacterial species elicit larval metamorphosis in H. elegans via at least two mechanisms, including outer membrane vesicles and phage-tail bacteriocins. We investigated the interaction between larvae of H. elegans and the inductive bacterium Cellulophaga lytica, which produces an abundance of OMVs but not phage-tail bacteriocins. We asked whether the OMVs of C. lytica induce larval settlement due to cell membrane components or through delivery of specific cargo. Employing a biochemical structure-function approach with a strong ecological focus, the cells and outer membrane vesicles produced by C. lytica were interrogated to determine the nature of the inductive molecule. Here we report that the cue produced by C. lytica that induces larvae of H. elegans to metamorphose is lipopolysaccharide (LPS). The widespread prevalence of LPS and its associated taxonomic and structural variability suggest it may be a broadly employed cue for bacterially induced larval settlement of marine invertebrates. Significance Statement New surfaces in the sea are quickly populated by dense communities of invertebrate animals, whose establishment and maintenance require site-specific settlement of larvae from the plankton. Although it is recognized that larvae selectively settle in sites where they can metamorphose and thrive, and that the biofilm bacteria residing on these surfaces supply inductive cues, the nature of the cues used to identify ‘right places’ has remained enigmatic. In this paper, we reveal that lipopolysaccharide (LPS) from the outer membrane of a marine Gram-negative bacterium cue metamorphosis for a marine worm and discuss the likelihood that LPS provides the variation necessary to explain settlement site selectivity for many of the bottom-living invertebrate animals that metamorphose in response to bacterial biofilms.
ALTERED VASCULAR REACTMlY IN CORONARY ARTERY DISEASE

The endothelial lining is metabolically very active and synthesizes powerful local hormones (autacoids), which diffuse into the adjacent vasculature and elicit decisive changes in vascular tone and conductance and therefore in or~an perfusion. A loss or an impairment of endothelium-dependent control mechamsms becomes particularly important under pathophysiological conditions, such as when endothelial function is disturbed due to atheromatosis, hypertension, diabetes, balloon catheter evoked endothelial denudation, several immunological diseases, including intimal vascular alterations following heart transplantation and other surgical interventions which affect endothelium mediated vascular control. The physiological and pathophysiological aspects of the endothelial autacoid release in the regulation of coronary vascular tone is described in this report with emphasis on the role of the endotheliumderived relaxant factor (EDRF).

This study aimed to (1) identify the publication and citation trends, (2) explore the distribution of paper types, (3) recognize the most relevant countries/regions, affiliations and authors, and (4) reveal relevant thematic features by analyzing publication abstracts and titles with the use of word cloud analysis and topic modeling analysis. The results highlighted several research hotspots and emerging topics such as Technology-enhanced classroom pedagogy, Blended learning, Online social communities, Mobile assisted language learning, Game-based learning and Socialized e-learning.
The effect of trick intervention 20-20-20 on computer vision syndrome incidence in computer workers

Computer Vision Syndrome is a collection of symptoms that occur due to overwork with computers, including laptops, desktops, tablets and other display devices (such as smartphones and other electronic reading devices). Resting your eyes continuously and regularly has a huge effect in overcoming the syndrome. The purpose of this study was to analyze the effect of trick intervention 20-20-20 on the incidence of computervision syndrome in computer workers. The research method used is Quasi Experimental Design with the form of Nonequivalent Control Group Design. The total sample of this study was 76 people divided into two groups, namely the intervention and control groups. The samples in each group amounted to 38 people obtained by purposive sampling. Bivariate analysis used the Wilcoxon test for paired samples and the Mann-Whitney test for unpaired samples with a significance level of 95% (α = 0.05). The results of statistical tests in the intervention group showed significant differences in the score of computer vision syndrome between before and after the intervention (ρ <0.05). The results of statistical tests between the intervention and control groups also showed a significant difference in the incidence of computer vision syndrome between the intervention and control groups (ρ <0.05). The conclusion in this study was that there was a significant effect of trick intervention 20-20-20 on the incidence of computer vision syndrome in respondents.
