Pathological study of some esophageal lesions of slaughtered sheep in Mosul abattoir

This study includes collection of 120 samples of sheep esophagus from slaughtered sheep in Mosul abattoir from December 2013 to March 2014 for detection of lesions and their incidence. Total 85 esophagus samples showed lesions from the total collected samples. The revealed lesions included disturbance of cell metabolism manifested by coagulative necrosis, sloughing of epithelial lining the esophagus and vacuolar degeneration at incidence rate 67.7, 23.5 and 17.6% respectively, circulatory disturbances like petechial, diffuse hemorrhage and edema were noticed at incidence rate 7.05, 4.7 and 3.5% respectively. Also results showed epithelial hyperplasia, fibroplasia and hyperkeratosis at 47, 24.7 and 31.7% of the total collected samples respectively, whereas eosinophilic inflammation of esophagus appeared at 3.5% of collected samples. Jaundice represent the disturbance in pigmentation reported at ratio of 16.4%, also additionally there was parasitic infestation represented by sarcocystosis and worm infestation which impeded in muscularis layer of esophagus at percentage ratio 50.5% and 3.5% respectively and a single case of esophageal diverticulosis was recorded at percentage ratio of 1.17%. Section that stained which Masson trichrome stain showed fibroplasia with proliferation of fibroblasts that take a bluish green color between muscle fibers.
EPM Effects on Workplace Well-Being: The Role of Personality

Within the workplace, electronic performance monitoring (EPM) is an electronically integrated system used to assess employee behaviours and ultimately performance. Previous research indicates EPM is associated with various negative psychosocial effects due to job roles being inherently changed with the use of these systems. However, research has yet to explore whether an individual's characteristics can also be attributable for influencing these outcomes. Therefore, the aim of this research was to investigate whether personality factors could moderate or mediate the negative effects of electronic performance monitoring. Using a quantitative survey methodology this project acquired 112 participants to assess the relationship between the amount of EPM they were exposed to and the levels of trust in senior management, affective commitment and self-perceived stress. The participants also completed the Conscientiousness and Emotional Stability scales from the Five Factor of Personality and a shortened version of Rotter’s Locus of Control. Regressional, Moderation, mediation and MANCOVA analysis were conducted to assess whether the personality factors held moderating or mediating attributes. The findings indicated that greater amounts of EPM did not predict lower levels of trust, commitment or an increase in stress. Furthermore, the Conscientiousness personality factor held no bearing on the negative effects of EPM, whereas Emotional Stability moderated the effects of trust and modestly meditated commitment and stress. The Locus of Control was also found to have influenced employees’ levels of trust. The current findings suggest the use of electronic performance monitoring does not radically change the job design to a degree where employees experience a decline in well being at work. However, whether the organisation's intention to use EPM is for supportive or punitive purposes is likely to have been a pivotal factor in how the systems are perceived. This highlights the need for policies and clear communication detailing why the information will be collected and how it will be used. In addition, some personality factors were found to modest factors contributing negative effects of EPM. In practice, this finding suggests occupations requiring intensive monitoring may be more appropriate for those with greater levels of emotional stability and who possess an internal Locus of Control.
Quantum Key Distribution: Boon or Bust

: Quantum Key Distribution (QKD) is an emerging cybersecurity technology which exploits the laws of quantum mechanics to generate shared secret keying material between two geographically separated parties. The unique nature of QKD shows promise for high-security applications such as those found in banking, government, and military environments. However, real-world QKD systems contain a variety of implementation non-idealities which can negatively impact system security and performance. This article provides an introduction to QKD for security professionals and describes recent developments in the field. Additionally, comments are offered on QKD’s advantages (i.e., the boon), its drawbacks (i.e., the bust), and its foreseeable viability as a cybersecurity technology.
Kidney Salvage with Renal Artery Reconstruction after Blunt Traumatic Injury

Renal artery injury from blunt abdominal trauma is a rare condition that is typically managed nonoperatively in hemodynamically stable patients. Revascularization can be achieved by stenting or surgical reconstruction of the renal artery. All attempts at revascularization should minimize warm ischemic time. Here, we discuss a patient postmotor vehicle accident who presented to Ryder Trauma Center with intra-abdominal bleeding. He underwent emergency exploratory laparotomy with splenectomy and abdominal packing. Postoperative CT scan revealed a contrast nonenhancing left kidney. The patient then returned to the operating room and underwent in situ renal artery reconstruction after >4 hours of warm ischemia. The patient survived a 2-month hospital course and was discharged home after prolonged in-hospital stay and intensive care treatment. Nuclear medicine scan showed scarring and atrophy of the reattached kidney with 16.3% of overall function attributed to the affected kidney. This case shows that patients with renal artery injury can be managed operatively with arterial reconstruction. Reducing warm ischemic time is critical in preserving kidney function.
NORDIC JOURNAL OF INFORMATION LITERACY IN HIGHER EDUCATION

This study investigates the influence of class instruction (GST 111 – use of library) on University of Benin (UNIBEN) first year students’ information and communication technology (ICT) literacy skills. The study adopted the survey research method using the questionnaire as research instrument. First year students in the 2013/2014 academic session constituted the population of study. Simple random and total enumeration sampling methods were used to collect data from students in five out of twelve faculties in the university. The questionnaire used is a 4-point likert scale instrument: SA (Strongly agreed) = 4; A (Agreed) = 3; D (Disagreed) = 2; and SD (Strongly disagreed) = 1. Data was collected at the end of the first semester when the GST 111 – use of library was concluded. Results revealed that Computer, Software, Internet, WWW and ICT literacy skills of the students are high. There is a significant difference in Computer, Software, Internet and WWW and ICT literacy skills of the students per faculty. Majority (65%) of the students are skillful in ICT use. Class instruction is very well perceived by the students and it positively influenced students’ ICT literacy skills. Gender and secondary school attended did not influence students’ ICT literacy skills. There is no significant difference between male and female students’ ICT literacy skills as well as students that attended private or public secondary schools. It is therefore concluded that the students are highly ICT literate and class instruction (GST 111 – use of library) course mainly influenced the students’ ICT literacy skills thus the class instruction programme in the university is adequate and effective.
A possible correlation of Ezrin and Fascin-1 in adenoid cystic carcinoma of salivary gland: an immunohistochemical study

Adenoid cystic carcinoma (ACC) of salivary gland is one of the most common epithelial salivary gland carcinomas and is characterized by extensive local tissue infiltration and poor long-term survival. All forms of ACC are characterized by prolonged but persistent growth, extensive perineural invasion and hematogenous metastases. Distant sites of metastasis are primarily lung, although bone and liver are also common. The incremental motility of malignant cells is a critical step in their migration, invasion and metastasis, which is regulated by reorganization of actin cytoskeleton and regulation of focal adhesion. Fascin-1 and ezrin are essential components of these cellular structures. The aim of this study is to evaluate the expression of these cytoskeleton-associated proteins in ACC as a prognostic indicator of invasiveness. Five cases of normal salivary gland tissue and 43 cases of adenoid cystic carcinoma (10 cases cribriform form, 15 cases tubular form and 18 cases solid form). Immunohistochmical staining for ezrin and fascin-1 antibodies were done for all specimens. Statistical analysis was performed using a commercially available software program (SPSS 19; SPSS, Chicago, IL, USA). The level of significance was set at P < 0.05. For both markers, statistically, the greatest mean area percent was recorded in solid pattern ACC, whereas the lowest values were recorded in normal tissue. These results indicating a synergistic effect between ezrin and fascin-1 during ACC invasion.
A Cross-Sectional Study of the Impact of Antipsychotic Medications on the Hematological Profile of Patients with Schizophrenia in a Tertiary Health Facility in Uyo, South-South, Nigeria

Objective: Antipsychotic drugs have been implicated as a potential cause of haematological toxicity. However, the seemingly mild and asymptomatic presentation is perhaps responsible for it not being frequently investigated. The aim of this study, therefore, was to determine the effect of antipsychotic drugs on the hematological profile of patients with schizophrenia. Methods: This was a descriptive cross-sectional study involving 100 participants i.e. 60 subjects and 40 controls. 2.5 mls of blood was obtained from each participant for determination of full blood counts. Clinical data of subjects including their demographic characteristics, classes of antipsychotics, and duration of antipsychotic usage were obtained from their respective case files. Data was analysed using Statistical Package for Social Sciences for Windows Version 17. Significant level was set at p<0.05. Results: The mean of the hematological parameters including haemoglobin concentration, absolute neutrophil counts and platelet counts were significantly lower among the subjects than the controls p=0.001, 0.04 and 0.001 respectively. Similarly, there was statistically significant differences in the mean platelet count, MPV and PCT of subjects and controls with p<0.001, 0.001 and 0.04 respectively. However, there was no association between the mean age and gender of subjects and absolute neutrophil count p=0.24 and 0.46 respectively. Conclusion: Significant reduction in haematological parameters of subjects compared to the controls may suggest some degree of haemato-toxicity most likely attributable to the antipsychotic drug. Furthermore the absolute neutrophil count though significantly lower in the subjects did not show age or sex differences. Therefore, there is need to regularly monitor haematological indices of psychiatric patients during treatment with antipsychotics.
DFT Study on Adsorption of Acetone and Toluene on Silicene

In this work, we investigated the adsorption mechanism of acetone and toluene on the surface of silicene by the quantum simulation method. The images of the potential energy surfaces for different positions of the adsorbate on the silicene surface were explored by Computational DFTbased Nanoscope tool for determination of the most stable configurations and diffusion possibilities. The charge transfer in order of 0.2 – 0.3 electrons and the tunneling gap opening of 18 – 23 meV due to acetone and toluene, respectively, suggest that silicene is considerably sensitive with these VOCs and can be used as the material in the fabrication of reusable VOC sensors.
PHYLOGENETIC RELATIONSHIPS AMONG WEST INDIAN XENODONTINE SNAKES (SERPENTES; COLUBRIDAE) WITH COMMENTS ON THE PHYLOGENY OF SOME MAINLAND XENODONTINES

The evolutionary relationships of the West Indian (W. I.) xenodontine snake assemblage has been considered as either monophyletic or paraphyletic. Allozyme data from protein electrophoresis were used to estimate the phylogeny of the W. I. xenodontine snakes. Forty-two species from 25 genera (mainland and W. I. taxa) were examined. The phylogenetic relationships were estimated using parsimony analyses with successive approximation weighting on the data coded two ways: (1) the allele as the character and (2) the locus as the character. The most parsimonious trees from both coding methods indicated a non-monophyletic W. I. xenodontine assemblage. Three W.I. groups were recovered in both coding methods: (1) Jamaican Arrhyton and Darlingtonia, (2) Uromacer and the Cuban Arrhyton, and (3) Alsophis, Ialtris, and the South American Alsophis elegans. The relationships of Hypsirhynchus, Antillophis and Arrhyton exiguum were unstable. Nomenclatural changes are recommended for Darlingtonia, Arrhyton, Ialtris and Alsophis.
Correlation between Off-flavor and Morphology of Papaya (Carica papaya L.) Fruits

Aims: To investigate the correlation between fruit morphology and off-flavor characteristics which are naturally present in papaya. Place and Duration of Study: Department of Food Science and Technology (Sensory Laboratory and Food Analysis Services Laboratory), Centre for Tropical Horticulture Study (Chemistry Laboratory) and Indonesian Centre for Rice Research of Indonesian Agriculture Ministry (Flavor Laboratory), between December 2014 and September 2015. Methodology: Morphology descriptions of 6 papaya varieties, i.e. “Carisya”, “Callina”, “Sukma”, “Merah Delima”, “Burung” and “Bangkok”; off-flavor description using Quantitative Descriptive Original Research Article Kamil et al.; JEAI, 42(1): 121-132, 2020; Article no.JEAI. 54664 122 Analysis; semi-quantification of volatile compounds by using Headspace Solid-Phase MicroExtraction and Gas Chromatography-Mass Spectrometry have been conducted. Results: The stinky-sour odor had positive correlation with the presence of butanoic acid (r=0.879) and octanoic acid (r=0.876). The stinky-sour odor had negative correlation with the weight (r= 0.836), length (r= -0.873), flesh thickness (r= -0.887), and ripe peel color (r= -0.838) in accordance to the octanoic acid content which showed negative correlation to fruit weight (r= -0.871), length (r= -0.830) and ripe peel color (r= -0.911). The stinky-sour odor as well as the concentration of butanoic and octanoic acid were most dominant in “Burung” and “Carisya” papayas. “Callina” and “Sukma” papayas had the weakest offflavor intensity. Conclusion: The off-flavor perception of papaya was dominated by stinky-sour odor. The presence of octanoic acid might deliver synergism impact to butanoic acid in giving the perception of stinkysour odor. High concentration of octanoic acid and strong intensity of stinky-sour odor were closely related to the small type of fruit weight (650 g or less), short size fruit (16.5 cm or less), thin flesh (less than 3 cm), and papaya varieties with orangish ripe peel color. These phenomena can be utilized in selection process in the field selection criteria to breed favorable papaya varieties.
MEDIA EDUCATION AND DIGITAL INCLUSION: TACKLING THE SOCIAL EXCLUSION OF DISADVANTAGED GROUPS IN EUROPE

Media literacy has been one of the main strategies for promoting the inclusion of disadvantaged groups in Europe. These policies that favour empowering uses of media and information are based on the knowledge that it is not enough to guarantee access to ICTs. Cultural and social environments can say a lot about the uses of the media and how the information is used as a capital for personal and collective development and empowerment. Social exclusion is a multidimensional process. Following the European values that place knowledge at the heart of social and economic development, international institutions have focused on policies that promote social cohesion by favouring empowering personal uses of the media. In recent years, fighting the digital divide became less about access and more about its uses. The role of media and technology in the process of social development is not underestimated. They are seen as instruments for having citizens that are more active and participative. This paper analyses recommendations and proposals that address social inequalities in the European Union through the promotion of media literacy. This analysis shows that there is a consensus regarding the acquisition of skills that can promote critical thinking and offers a deeper understanding of the various dimensions that are favoured in the European context.
Potentially Preventable Mortality in the Pediatric Intensive Care Unit: Findings from a Retrospective Mortality Analysis

Objective The goal of this study was to estimate the proportion and causes of potentially preventable mortality among critically ill children admitted to the pediatric intensive care unit (PICU). Methods The medical records of all patients who died in the PICU (age range: one month to 16 years) between January 2014 and December 2015 were evaluated by two independent reviewers to determine whether there had been any delayed recognition of deteriorating conditions, delayed interventions, unintentional/unanticipated harm, medication errors, adverse reactions to transfusions, and hospital-acquired infections that could have resulted in unanticipated death. Preventability was labeled on a 6-point scale. Results During the study period, 92 of 690 patients did not survive [median age: 60 months, interquartile range (IQR): 114]. The median Pediatric Risk of Mortality (PRISM) III score was 17 (IQR: 6). Major diagnostic categories included sepsis (n = 29, 35%), central nervous system diseases (n = 16, 17%), oncological/hematological diseases (n = 6, 6%), cardiac diseases (n = 4, 4%), and miscellaneous conditions. None of the deaths had definitive or strong evidence of preventability. Four (4.3%) patients were in category 4 (i.e., possibly preventable, >50/50 chance), 15 (16.3%) in category 3 (possibly preventable, <50/50 chance), 28 (30.4%) had some evidence of preventability, and 45 (49.0%) were labeled as definitely not preventable. Late identification (diagnostic error) of the worsening condition in four (21.0%) patients, slow intervention in six (31.6.0%), and hospital-acquired infections in 10 (52.6%) were found to be related to potentially preventable mortality. Conclusions Preventable diagnostic errors and nosocomial infections (NIs) are major contributors to preventable mortality. Structured mortality analysis provides actionable information for future preventive strategies. Improvement in care processes, including clinical decision support systems, could help reduce preventable mortality rates.
The Control Of Postoperative Pain Following Oral Surgical Procedures By Ibuprofen Or Acetaminophen

Aim: The aim of this study was to compare the effects of anti-inflammatory (ibuprofen, 600 mg) and analgesic (Acetaminophen, 750 mg) drugs on postoperative pain. Material and methods: Patients with indications for surgery were selected, and a total of 57 patients, 20 male (35.1%) and 37 female (64.9%) were included in the study. Of these, 26 patients were placed in the acetaminophen group, and 31 were placed in the ibuprofen group. The average age of the patients was 30 years. The following types of surgeries were included in the evaluation: clinical crown lengthening, gingivectomy, pre-prosthetic surgery, labial frenum and frenum lingual. The surgeries were performed by students in a postgraduate training program in periodontics. Subsequent surgery, postoperative period orientations were provided by the researcher, and the medication to be prescribed was selected at random allocation. Both medications were administered for 48-h periods. A visual analogue scale with values ranging from 0 to 10, where 0 represented no pain and 10 represented maximum pain, was provided to the patients, and the patients were asked to rate their pain using this scale each time they took the medication. At the time of the follow-up visit, the patient data were given to the researcher and subsequently tabulated and applied to the statistical analysis (Mann-Whitney, p<0.05). Results: The results showed no significant difference in pain between medications (p>0.05). Conclusions: There was no difference in postoperative periodontal surgery pain after the use of anti-inflammatory or analgesic drugs.
Perceived sources of stress among dental students in Port Harcourt

Dental education is regarded as a stressful learning environment due to the clinical and laboratory requirements as well as in-depth theoretical knowledge. Therefore the objective of this study was to identify sources of stress among dental students in University of Port Harcourt, Rivers State. The study was a descriptive cross-sectional study among undergraduate dental students at the University of Port Harcourt, Rivers State. The students were surveyed using a modified version of the Dental Environment Stress (DES) survey. Age, sex, year of study, marital status and monthly allowance were also recorded. All descriptive, as well as inferential statistical analysis, was carried out using SPSS ver. 20.0 and the value of p 0.05). The most common causes of moderate to severe stress were lack of time for relaxation, workload, the responsibility of getting suitable patients and fulfilling clinical requirements. There was no significant difference in the perceived stress levels across gender and level of study. The commonest stressors were workload and lack of relaxation time. There is a need to re-examine the dental curricula to identify ways to reduce workload. Also, there is a need to implement strategies to manage stress among dental students.
Study of Chromosomal Abnormalities in Couples with Recurrent Spontaneous Abortions (RSA) in Ardabil Province

Background & objectives: The spontaneous abortion, loss of the fetus until the twentieth week of pregnancy, is one of the most common medical problems in reproductive age. Approximately 15 to 20 percent of all clinically recognized pregnancies lead to abortion. Failure in pregnancy involves economic costs, physical and mental problems for the family and the society. Recurrent spontaneous abortion is a multifactorial phenomenon and this study analyzed chromosomal abnormalities and the prevalence of consanguineous marriages in parents with recurrent spontaneous abortions in Ardabil province. Methods: A total of 350 patients with at least two spontaneous abortions were analyzed using GTG-banding cytogenetic technique. Results: Parental chromosomal abnormalities were found in 18 cases (10.28% of couples). Most of abnormalities were structural (72.2%). chromosomal aberrations were found in 10 (55.6%) females and 8 (44.4%) males. Translocations were the most common chromosomal abnormalities (55.6 %) diagnosed in this study. Also, there was a significant correlation between recurrent spontaneous abortion due to consanguineous marriage and chromosomal abnormalities (p<0.05). Conclusion: According to the significant correlation between recurrent spontaneous abortion and chromosomal abnormalities in this study and previous studies, and also the high rate of consanguineous marriages in Ardabil province population, analysis of chromosomal abnormalities is necessary after genetic counseling for both parents with recurrent spontaneous abortions.
