Abstract: Introduction: Occupation is one in all the principal components of our everyday lives that would motive a quality of pressure. Stress and Professional Exhaustion Syndrome (burnout) are connected collectively. The relationship linking musculoskeletal disorders (MSD) and burnout syndrome as a psychosocial element was documented earlier. Objectives: The object of this be taught was to determine the role of work-related strain and burnout in musculoskeletal illness amongst foreign staff of various international companies in Egypt. Substances and Methods: A total of 253 workers representative for the international petroleum companies in Egypt were participated in a cross sectional study. The contributors have been chosen conveniently from all of the available international companies’ peoples. Only 166/253 (response fee: 65.5%) of the participants were involved in the present work and complete the questionnaires. An evaluation of burnout and MSD have been made using the Nordic questionnaires and Maslach Burnout Inventory (MBI). The work place stress was calculated through the work place stress questionnaire. Results: The average occupational stress (17.18 ± 3.42) was elevated significantly (P = 0.02) amongst foreign subjects complained from MSD than between the normal subjects (16.06 ± 2.19) in the course of the former week; and also during the past year (17.17 ± 3.11 and 16.74 ± 3.03, respectively; P = 0.01) to the study. Both of occupational stress and smoking habit only were identified as impartial predictors of MSD amongst foreign subjects. Conclusions: It appears that linkage between musculoskeletal complaints and burnout syndrome was more complex than being returned to only occupation stress. Additional studies are encouraged to investigate different associated motives to these organizations.

Abstract: Background: Recurrent miscarriage represents a major concern for reproductive medicine. Nitric oxide plays a major role in improvement of uterine perfusion during the luteal phase and early pregnancy. This study was done to compare uterine artery and sub-endometrial blood flow indices during the luteal phase between patients with recurrent miscarriage and fertile women and also to evaluate the effects of nitric oxide donors on blood flow indices in the patient group. Methods: The study included a control group of 40 women with good obstetric history (delivered at least one child), do not have abnormal findings in routine examinations for female factor and are not primigravidae and a patient group of 40 nulliparous women with history of two or more unexplained recurrent miscarriage. Transvaginal three-dimensional pulsed color Doppler ultrasound was done on days 21 of the cycle to measure uterine artery resistance and pulsation indices. The effect of nitric oxide donors was evaluated in the study and control group by placing 20 mg Isosorbide Mononitrate vaginally. Pulsatility index (PI) and Resistance Index (RI) of uterine artery were measured after two hours. The Student t-test and the paired t-test were used for analysis of results and a p-value of ≤0.05 was considered significant. Results: Patients with unexplained recurrent miscarriage had significantly higher uterine artery resistance and pulsation indices (p<0.01). Isosorbide mononitrite significantly decreased uterine artery blood flow indices (p<0.001). Conclusion: Uterine artery blood flow decreased during the lutealphase in patients with unexplained recurrent miscarriage. Nitric oxide donors increased blood flow and may be of a therapeutic value.

Abstract: Background: With the expanding subpopulation of women with prior cesarean. births, second trimester pregnancy termination in patients with a prior cesarean delivery has become an increasing lycommon circumstance facing obstetricians. Objective: determine the safety and efficacy of vaginal misoprostol in termination of second trimester pregnancy in women with prior uterine incisions. Patients and methods: This is a case series study that was included 50 patients in their 13‐26th week's gestation according to dates or first trimestric ultrasonography, with previous one or two lower segment cesarean section in whom termination of pregnancy was indicated either due to intrauterine fetal demise or lethal structural anomalies. Results: Successful termination was generally considered to be the expulsion of the fetus within 72 h. In our study, the overall success rate was 92 % with 18.7 ± 9.8 hours mean induction– abortion interval 18.3 ± 9.3 hours in patients of the second group (range: 6.5 – 38.0 hours). This relatively long duration may be attributed to the relatively small dose we used Misoprostol 200 μg vaginally or sublingual or buccal every 4 hours up to 4 doses within 72 hours only. N.B. we avoid vaginal route if bleeding and/or signs of infection. Conclusion: The use of the prostaglandin E1 analogue, misoprostol, in a dose of 200 μg /4 hours is safe and effective for induction of second trimestric abortion in women with previous uterine incisions.

Abstract: We have studied theoretically formation of molecular ion K2+ and the atomic ion K+ which are createdin laser-excited potassium vapor at the first resonance transition, 4S - 4P. A set of rate equations, which describe the temporal variation of the electron energy distribution function (EEDF), the electron density, the population density of the excited states as well as the atomic K+ and molecular ion K+2, are solved numerically. The calculations are carried out at different laser energy and different potassium atomic vapor densities under the experimental conditions given by Amin et al. [19]. In this experiment, the potassium atomic density was varied in the range from -3; the vapor temperature was 540 K˚, and the laser repetition rate was 10 Hz. The intensity of the exciting laser beam is 0.5 mJ, while the intensity of the ionizing laser beam was varied in the range from 0.1 to 1 mJ, and the laser beam diameter was varied in the range 230 - 290 mm. The numerical calculations of the electron energy distribution function (EEDF) show that a deviation from the Maxwellian distribution due to the super-elastic collisions effect. In addition to the competition between associative ionization (4p-4p), and Molnar –Hornbeck ionization processes for producing K2+, the calculations have also shown that the atomic ions K+ are formed through the Penning ionization and photoionization processes. These results are found to be consistent with the experimental observations.

Abstract. Inclusion of feed additives in the winter diet of pregnant mares increases the consumption of crude protein on 3-21%, for digestible 4-32%. In the summer experience, when grazing on alas and valley meadows Yakut mares consume an average of 330 g per day of crude protein per day on 100 kg live weight 211 g of digestible protein. This is according to 5 experiments. In winter, the consumption of crude protein was at 209 g per day per 100 kg live weight on digestible protein, 136 g for an average of four experiments with data on natural herbage of winter pasture. During summer, the horses’ body is intense accumulation of reserve elements, increasing fatness, first by increasing muscle mass, further due to the deposition of subcutaneous fat and visceral fat in the abdomen. At this time in our experiments mare consumed 330 g per day on 100 kg live weight.

Abstract: Most nosocomial infections are thought to be transmitted by the hands of healthcare workers. The aim of this work was to assess the knowledge, attitude and practice of hand washing among healthcare workers (HCW) in Al-Azhar University hospitals and to investigate the presence of the necessary facilities and supplies required for hand washing (HW) in ten wards. A cross sectional descriptive and observational study was conducted for six months from June till November 2016. Observation of the HCW for hand washing practice was done at any opportunity of contact with the patients in the different wards by members of the infection control team. Knowledge & attitude of HCW towards hand hygiene was done through self-administered questionnaire to HCW in 10 different departments. The total opportunities observed were 2189 opportunities. Doctors showed a significantly higher compliance (37.5%) than other groups of HCW (P = 0.000), however only 11.6% of the opportunities observed for doctors were done appropriately. The most common type of HW practiced among HCW was the routine HW (64.3%) and the least was the antiseptic HW (3.9%). Having a short contact time and improper drying (23.2%) were the most common errors that lead to inappropriate HW. Most of the wards had available sinks (80%) but none of them had available paper towels. The mean knowledge score was higher in nurses compared to doctors (42.6 ± 11.7 versus 39.1 ± 10.5). Most of the nurses (97.3%) believe that administrative orders and continuous observation can improve hand washing practices. Implementation of multifaceted interventional behavioral hand hygiene program with continuous monitoring and performance feedback, increasing the supplies necessary for HW and institutional support are important for improving the compliance of hand hygiene guidelines.

Abstract: In order to investigate the proliferative and apoptotic effects of shikonin on human hepatoma cell line HepG-2, this research observed morphological alterations with phase contrast microscopy, detected apoptotic rates, cell cycle progression, mitochondrial transmembrane potential. The results suggested that typical apoptotic morphological alterations occurred after shikonin treatment. Shikonin exerts a strong inhibitory the proliferation of HepG-2 cell line, and induces its apoptosis in a dosage and duration dependent manner. Cell cycle was arrested at G0/G1 phase. Mitochondrial transmembrane potential dropped. It is concluded that shikonin can induce apoptosis of HepG-2 via arresting cell cycle progression, reducing mitochondrial transmembrane potential. Although our present study is preliminary, shikonin could potentially be a therapeutic agent for the treatment of hepatocellular carcinoma.

Abstract: This paper is concerned with the design and dynamic modelling of four degrees-of-freeedom (DOFs) spatial manipulator with experimental validation which will provide the essential insights to control the system. Two different approaches were employed for dynamic modelling of the system; they are the physical finite element (FE) method and the experimental data-based model in discrete time transfer function (TF). A comparison between the two approaches is carried out, in terms of modelling accuracy, along with experimental validation by real time implementation of the manipulator. In the first approach, each link was treated as a finite element and total displacement was derived by means of the shape function of each element. However, in the second approach, experimental on-line data were used to derive the discrete time TF of each link. The comparison study of the real time implementation suggests that both approaches provide acceptable modelling for the manipulator in terms of torque exerted by each joint when the end-effector trace a specified path in a given time; however the experimental data-based approach shows acceptable accuracy with straightforward modelling when compared to modelling using.

Abstract: Child’s eye view is the thinking and poetic style of the contemporary poet Sohrab Sepehri. This view is present in various ways in Sepehri’s poetry. He used childhood memories as a poetic asset. Sepehri maintains a sincere, honest, and, yet, simple tone to explain his mystical revelations and apperceptions. His tone is a mixture of childish, poetic, and symbolic verbiage. His far reaching imaginativeness resembles a child’s unlimited imagination trying to establish new relations and pertinences between objects and events. Sepehri’s child like approach to poetry helped him create novel, strange, and unprecedented imageries whose variations and freshness are unconscious reminders of heterogeneous and diverse reflections of childhood imaginations. His child’s eye view observes activities and events without conventions, prejudice, and predispositions. Sepehri presents a trickle of freshness, wonder, and pleasure in his poetry that rivals with what children experience. This article is a study into the resemblance between Sepehri’s mythical views and children perceptions. It is an attempt to uncover and explain Sepehri’s thoughts, emotions, imaginations, and language as presented in his poems.
