Abstract: The present study was carried out in AHRI (Aquaculture Disease unit) from January 2020 to April 2020, to evaluate the impact of aquaponic system on water quality and health of Oreochromis niloticus. Fifty apparently healthy fingerlings fish were collected and divided equally into two groups representing aquaponic system and the aquaria (control). Water quality was measured on basis of both daily Temperature (thermometer), pH (PH meter), Dissolved Oxygen and weekly for 8 weeks, total Ammonia, NO2, NO3, and Growth rate (measuring by ruler). Results of water analysis showed improvement of water quality parameters in aquaponic system. Total bacterial count (TBC) of water and fish skin and gills revealed that the (TBC) in both aquaponic and aquaria were nearly similar and ranged from 6.6×10⁵ to 12.4×10⁵ (CFU/ml) at the beginning of the experiment. At the end, The (TBC) increased in aquaria with water had the highest number of bacteria 11.1×10⁵ (CFU/ml). The most prevalent isolates from aquaria and aquaponic were Aeromonas hydrophila with (30% and 20%) isolation rate respectively. Pseudomonas spp. were isolated with a percentage of (20%) from aquaria and (15%) from aquaculture. E.coli was also identified in (15%) of the examined samples of each system. While one isolate of staphylococcus aureus was isolated only from aquaria. The highest isolation rates were from skin of fish and water. PCR was applied on five isolates from each bacterial species for the detection of 16S rRNA as an accurate method for isolate identification.

Abstract: Hs-CRP Inflammatory biomarker may provide means for early detection of metabolic syndrome. Objective: to assess the value of high-sensitivity CRP in serum of pre-diabetic and recently diagnosed clients with type 2 diabetes mellitus. Subject and methods: This trial was carried out on 180 individuals coming to the medical outpatient clinic of Fayoum University Hospital. The aged ranged from 20-60 years. They were classified into three groups. The control group I: was consisted of 60 non-obese, non-diabetic healthy volunteers, .Two study groups were involved in this investigation: group II was consisted of 60 newly diagnosed patients with type 2 DM and group III: was consisted of 60 pre-diabetic patients coincided for age and gender. All patients involving the control were exposed to clinical history taking, a clinical examination for the recording of body mass index (BMI) and (WC). Tests were conducted for fasting blood glucose, fasting serum insulin, insulin resistance (IR), HbA1C, the lipid patterns, liver and kidney function tests were carried out, serum albumin, a complete blood count (CBC) and serum high-sensitivity C-reactive protein (hs-CRP). Results: the current data showed that pre- diabetic patients and new diagnosed diabetic patients have higher levels of hs-CRP titre and HOMA-IR than normal healthy control. This difference was statistically significant difference. Conclusion: Hs-CRP was significantly elevated in obese pre diabetics and newly diagnosed type2 diabetics. Since hs-CRP is an important clinical parameter for assessment of the low grade inflammation occurring in metabolic syndrome and diabetes, therefore sequential rise of this inflammatory biomarker could assist in the early recognized of obese type 2 diabetic clients at high cardio metabolic risk.

Summary:

·       Obesity is a main risk factor for various chronic diseases, Involving insulin resistance and type 2 diabetes.

·       Hs-CRP is an acute-phase protein, its serum level is enhanced in response to inflammation in the body. It is synthesized by the liver in response to factors released by macrophages and adipocytes.

·       This work aimed to assess the value of high-sensitivity CRP in serum of pre diabetics and newly diagnosed patients with type 2diabetes

·       This work showed a statistically significant difference of hs-CR in pre diabetics and recently diagnosed diabetics in comparison to normal population.

·       Serial rise of hs-CRP denotes a deterioration of the inflammatory status in the body and there by a worsening of endothelial function thus increasing possibility of complication.

Abstract: Diabetes Mellitus is a popular persistent disease and apply a massive load on community due to its widely spread, the persistent nature of disease and the altitude hazard of main complications applies. Aim of the work: These investigations were carried out to detect the wide spread e of type II DM, predominance of unknown type II diabetic patients, glycemic monitoring state and correlated risk factors and complications of type II DM between inhabitance of Fayoum governorate. Patients and methods: The study included 3500 subjects (1440 males&2060 females) inducted from Fayoum Governorate, and their ages range from 18 to 60 years old. The entire medical history involving the patient's age, gender, history of DM, medication employed in remediation of type II diabetes, duration of type II DM, family history of type II DM, history of hypertension, and history of smoking. All the individuals were assessed for the risk of having  type II DM based on (weight, height, waist circumference, BMI, measurement of blood pressure, RBS).Also HbA1c, serum creatinine, lipid profile (cholesterol, TG, and LDL) were measured for  type II diabetic patients. Results: showed that the mean age of the study population was (44.04 ±13.2) years old and the mean period of type II DM was (5.01±4.6) years. This study showed that 14.2% knew that they had DM, 12.6 % were pre-diabetic, 10.5% were undiagnosed DM. Also this study showed that 35.7% show controlled type II DM versus 64.3% were uncontrolled. It was also found that 15.7% knew that they had hypertension, 13.5% were pre-hypertensive, and 10.5% were undiagnosed. Also majority of study population was overweight (31.1%) and obese grade I represent (22.3%), grade II (17.6%), and grade III obesity (8.1%). Conclusion: This study concludes that type II DM is a growing public health problem in Egypt. Prevention, early recognition, and efficient medications are essential parts of II DM in Egypt. These strategies may decrease the economic load correlated with type II DM.

Abstract: Background and Aims: We aimed to assess the relation between insulin resistance and serum 25-hydroxy vitamin D (25[OH]D) levels in both obese and non-obese children. Methods and Results: This cross-sectional study determined vitamin D levels of overweight children and their associations with insulin sensitivity, resistance, and glucose homeostasis. The study was conducted at the Childhood Obesity Clinic and Clinical Pathology Department, National Nutrition Institute, Cairo, Egypt, during January 1^st 2015 to June 1^st 2016. Obese participants had lower concentrations of 25(OH)D than non-obese participants but that was not notably different. The overweight group's 2-hour postprandial blood glucose level (2HRPP), fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR), and HOMA-B were all significantly higher than the control group's values, and then were linked to adiposity measures. Fasting blood sugar and hemoglobin A1c showed no statistically relevant differences in between the obese and non-obese groups. In the overweight group, 25(OH)D deficiency, insufficiency, and sufficiency (25[OH]D < 20 ng/dl, < 30, >20 ng/dl; ≥30 ng/dl, respectively) were not linked with insulin sensitivity or resistance indices. Blood pressure was positively associated with adiposity indices. Conclusion: The study showed no notably difference in vitamin D status among obese and normal, non-obese participants, but there was significant difference between obese and normal weight subjects regarding insulin sensitivity and resistance. Measures and 2-hour postprandial blood glucose level (insulin sensitivity and resistance indices were related to adiposity indices) and the increase in systolic and diastolic blood pressure was related to adiposity indices and insulin resistance.

Abstract: To remain survived, any organization requires new ideas. When workers are creative in their work, they will be able to suggest new and useful ideas on products, performance, services and events in the organization. Accordingly, the staff creativity greatly contributes to the organizational survival. Therefore, the present paper is an attempt to examine the relationship between emotional intelligence (EQ) and its categories and workers’ creativity. The research method is practical in terms of purpose and a survey-correlation study considering the method was used to collect the data. The research population also consists of all Iran Khodro Co. staff, which through Cochran’s formula 200 participants were selected through the simple random sampling method. To test the research hypotheses the SPSS software and descriptive –inferential statistics methods were applied. Moreover, the research model was fitted via the Amos software. the obtained results  indicate that a meaningful and positive association exists between emotional intelligence and its different dimensions including problem solving, sense of happiness, independency, stress tolerance, self-actualization , self-awareness, realism, interpersonal relations, optimism, self-esteem, impulse control, flexibility, responsibility, empathy and self-presentation) and the staff creativity . Furthermore, aspects of independency, stress tolerance, responsibility, problem-solving, and flexibility showed the highest rate of correlation with the staff creativity.

Abstract: The role of remote sensing and geographic information system (GIS) techniques is fast gaining prominence in the monitoring of vectors and infectious disease spread. Mosquitoes are important vectors of several diseases of humans across the world. In order to better understand some ecological aspects linking vegetation dynamics and vector population, we examined the spatial and temporal distribution of flora and malaria vector within university of Uyo town campus using GIS based techniques. The results showed that the flora and vector population varied significantly (P<0.05) between the studied locations per time within the campus. During the first week, the least mean (5.25) abundance of the vector was recorded at point 1 while the highest (28.5) was recorded at point 3. During the second week, the least mean (11.25) abundance of the vector was recorded at point 1 while the highest (29.25) was recorded at point 3. For the third week, the least mean (28.0) abundance of the vector was recorded at point 4 while the highest (58.25) was still recorded at point 3.  During the fourth week, the least mean (14.25) abundance of the vector was recorded at point 4 while the highest (43.0) was recorded at point 3. On the other hand, the vegetation comprised of 16 plants species (mostly herbs and grasses) from 11 families. Eleusine indica was the most frequently (75%) encountered species. Conclusively, patterns of variation in mosquito population were sensitive to vegetation dynamics in studied sites within the campus. These observations have application in ecology and public health.

Abstract: Previous researches have indicated that self-focused attention can be divided in to adaptive self-reflection and maladaptive ruminative factors. However self-reflection has two aspects, although it can prevent depression, self-rumination may spoil its adaptive effects. The aim of this study was to compare rumination and reflection in individuals with different severities of depression and normal people. Participants included 129 individuals (67 female, 62 male) with mild, moderate, severe or no symptoms of depression that were selected from clients of psychiatric hospitals or mental health center of Shiraz. Depressed subjects were selected based on a clinical interview and scores of Beck Depression Inventory II (BDI-II). Then they were assigned in mild, moderate and severe groups. Normal subjects were selected from people who had no mental disorder based on a clinical interview and scores of BDI-II. All participants completed the revised version of Rumination-Reflection Inventory (Fleckhammer, 2004), which is consisted of private and public subscales. Results showed that rumination increases as depression becomes more severe, but reflection is just lower in severe depression. Reflection in individuals with mild or moderate depression is not significantly different from normal subjects. Also, men and women were not different in rumination and reflection scores. These findings indicate that interactive effects of rumination and reflection vary in different severities of depression and in patients with severe depression; maladaptive effect of rumination can spoil adaptive effects of reflection.

Abstract: Sisal fiber has various advantages that make it a very promising concrete reinforcement material. These include its low cost, lightweight nature, excellent strength-to-weight ratio, lack of health hazards, and widespread availability in some places. To put its significance in context, roughly 4.5 million tons of sisal fiber are produced globally each year. The paper aimed to study the effect of length and proportions of sisal fibres on the characteristics of concrete. Compressive, tensile, bending strength, and water absorption were studied in the experimental program, in addition to the workability and microstructure of fibrous concrete. Short sisal fibres (SSFs) with lengths of 10 mm, 20mm, and 30mm, and different ratios of 0.4%, 0.8%, and 1.3% from cement weight were used. The results of the study indicated that Mix 9, which contains 30mm long SSFs with a percentage of 1.3%, showed the best results for compressive, tensile, and bending resistance of 37.52MPa, 37.52MPa, and 5.12MPa, respectively. Increasing the percentage of SSFs reduced workability, but in general, workability was acceptable, as sample M3 showed a slump of 9.8mm. The longer the fibres, the better the cohesion between the fibres and the cement paste, and this is reflected in the improvement of the results. Samples containing SSFs show a noticeable improvement in stress redistribution, crack arrest, and the microstructure of concrete.
