Seasonal biodiversity and ecological studies on the epiphytic microalgae communities in polluted and unpolluted aquatic ecosystem at Assiut, Egypt

A qualitative and quantitative study on epiphytic microalgae was carried out seasonally from November 2015 to August 2016 to follow up their community structures on aquatic macrophytes related to some physico-chemical properties of two polluted and unpolluted water bodies at Assiut, Egypt. A total of 169 species related to 64 genera of epiphytic microalgae were recorded. The most dominant algal group was Bacillariophyceae (43.2%), followed by Chlorophyceae (34.91%), Cyanophyceae (20.71%) and Euglenophyceae (1.18%). The total number of epiphytic algae fluctuated between 11.1 × 104 ind.g-1 plant dry wt. on Phragmites australis in summer at Nazlet Abdellah (polluted site) and 10.02 × 107 ind.g-1 plant dry wt. on Myriophyllum spicatum in winter at El-Wasta (unpolluted site). Some epiphytic microalgae were dominant as Pseudanabaena limnetica, Calothrix braunii, Scenedesmus acutus, and Ulnaria ulna. Others were specific on certain macrophytes as Aphanocapsa thermalis and Ulothrix sp., which grow on Phragmites australis, while Synechocystis minuscula attached itself on Myriophyllum spicatum. Analysis of PERMANOVA showed that the most important factors that induced the variation in epiphytic microalgae were the temporal variation and host plant. Water temperature, pH, nitrate, chloride, phosphate and total dissolved salts were the highest abiotic factors correlated with the variation in composition of epiphytic microalgae

World Health Organization Surgical Safety Checklist with Addition of Infection Control Items: Intervention Study in Egypt

BACKGROUND: Surgical team is in command of the operating room (OR) and takes decisions regarding various patient care procedures. Educational programs directed to them, should be creative, provocative and tailored to their specific needs and the expected outcomes. AIM: This study aims to design and conduct an educational program of patient safety and infection control for the OR team based on the WHO surgical safety checklist and to assess their post-intervention knowledge and practices. METHODS: This interventional study was conducted at the ORs of Port-said general hospital. It passed through three stages; baseline assessment of knowledge and practice regarding patient safety and infection control among OR team (surgeons, anaesthetists and nurses), intervention stage in which an educational program based on the WHO surgical safety checklist with modifications and additions of more infection control items was conducted, then re-assessment of their post-intervention knowledge and practices. RESULTS: All the studied participants showed improvement in both knowledge and practices of patient safety and infection control after the educational program based on the WHO surgical safety checklist with modifications and additions of more infection control items and including not only practices but also knowledge as well, than before. CONCLUSION: The modification of the WHO surgical safety checklist to fit local knowledge and practices created a comprehensive tool that led to an improvement in both knowledge and practices of patient safety and infection control among the OR team

NATURAL ANTIMICROBIAL ACTIVITY OF LAWSONIA INERMIS AND INDIGO TINCTORIA AGAINST CLINICALLY ISOLATED MICROORGANISMS

Objective: The present study aimed at evaluating the natural antimicrobial activity of Lawsonia inermis (L. inermis) and Indigofera tinctoria (I. tinctoria) against a reference and pathogenic clinically isolated strains compare with some antibiotics.Methods: The antimicrobial activity of Lawsonia inermis (red henna) and Indigo tinctoria (black henna) was evaluated against clinically isolated strains from urinary tract and wounds infected patients. The six tested strains namely were Staphylococcus aureus, Enterococcus fecalis, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa and Candida albicans. The antimicrobial activity was evaluated by agar diffusion method and microplate dilution for measuring the minimum inhibitory concentration (MIC). An American Type Culture Collection (ATCC) of bacteria was used as a control for confirming the type of the isolated bacteria.Results: Both red and black henna showed variable antimicrobial activity against tested bacteria and C. albicans. Alcoholic and oily extracts were more effective than water. Staphylococcus epidermis was significantly affected with water extract of black henna (20±1.1) and red henna (11±0.5). Nigella sativa oil extract with black henna had showed significant synergism effects against some microorganisms as Enterococcus fecalis (40±1.5), P. aeruginosa (15±0.9) and Candida albicans (18±0.6).Conclusion: Black and red henna had antibacterial and antifungal activities. They exhibited synergistic effects when mixed with black seed oil

COMPOUND BINARIZATION FOR DEGRADED DOCUMENT IMAGES

ABSTRACT In this paper, we propose a new binarization method for degraded document images. Hence, the existing work is focus on finding a good global or local method in order to remove smear, strains, uneven illumination etc. We propose a new compound method that combines the advantages of both global and local thresholding methods. Our method is applicable for various types of degradation cases and the value of factors could be determined automatically. We compare our method with five state-of-the-art degraded document images. It also has been tested over the dataset that is obtained from the recent Document Image Binarization Contest (DIBCO) 2011 and 2013 for the experiments. Experimental results prove the effectiveness of the proposed technique compared to previous methods

Do People Live at Sea Level and the Dead Sea Level Have Different Patterns of Anti-Hypertensive Drugs

Background: people live at various areas of sea level may have different patterns of anti-hypertensive drugs. Such a relation has never been reported in Jordan. Study objectives: the current study investigated how the sea level will impact the prevalence of hypertension in these areas, and how will affect the pharmacological properties of such a population. Methodology: a cross-sectional study design was involved to collect data from study participants. A total of 1000 participants were randomly selected from the two study areas. 500 participants from each. Participants were matched for age and gender. Blood pressure were measured for all participants. Blood samples were withdrawn to investigate the level of angiotensin II. Data was collected through organizing a working excel sheet and was further analyzed through using SPSS version 20. Data was presented as means, standard deviations, frequencies and percentages. The relationships between variables were examined using independent T-test. Significance was measured at an alpha < 0.05. Study findings: the main findings of the present study were that the mean of SBP is significantly higher in the Dead Sea (122.42±10.53 mmHg) than the Sea level area (118.07±11.64 mmHg), (p=0.001). Another significant variable was MBP which its mean was 91.64 ± 8.90 mmHg in the Dead Sea and 89.84 ± 8.72 mm Hg. The difference in the mean was statistically significant (p=0.001). The level of angiotensin II was 8.84 ± 4.65pg/ml in the Dead Sea area and 11.21± 6.05pg/ml in the area of the Sea level. The difference in the mean of the two study areas was not statistically significant (p>0.05). Conclusions: although the level of angiotensin II was not significantly varied between the study areas, but its trend was to be higher in the Sea level area. It was surprised to have higher levels of SBP and MBP in the Dead Sea rather than the Seal level area. It can be implied that the therapeutic options of hypertensive drugs follow different patterns independent of angiotensin II pathways

Awareness of Chronic Kidney Disease Evaluated Using Validated Questionnaire in Minia Governorate Public

Background: Awareness and education of kidney disease has an impact on its effective management and will reduce the economic and public health burden. Objective: We conducted a cross-sectional descriptive study to assess the level of awareness, knowledge and common risk factors of CKD in the community to plan to preventive modalities.Patients and methods: We used a pretested validated questionnaire to gather information about sociodemographic knowledge and risk factors of CKD from 464 residents aged >18 years.Results: A total of 464 residents completed this study with a median age of 30 years, 50.5% of them were females. The mean knowledge score of chronic kidney disease (CKD) was relatively poor as it was 13.12% ± 3.95. Only 48.6% could mention at least one function of the kidneys with 66.4% agreeing with that certain medications can help to slow-down the worsening of chronic kidney disease. A laboratory test for kidney function was known by 75.9%. 92.9% and 17.2% believe that CKD can be cured by spiritual means and herbal concoctions respectively. Abdominal obesity and excessive stress were seen in 64.7% and 45.5% respectively. Hypertension was seen in 56.5% while diabetes mellitus was found in 57.1% as risk factors for chronic kidney disease. Conclusion: Efforts should be made to increase the public knowledge of CKD in Minia, Egypt as it was relatively poor that may be achieved by increasing awareness, education of people about CKD and how to prevent or regress its risk factors

ZC3H11A loss of function enhances NF-κB signaling through defective IκBα protein expression

ZC3H11A is a cellular protein associated with the transcription export (TREX) complex that is induced during heat-shock. Several nuclear-replicating viruses exploit the mRNA export mechanism of ZC3H11A protein for their efficient replication. Here we show that ZC3H11A protein plays a role in regulation of NF-kappa B signal transduction. Depletion of ZC3H11A resulted in enhanced NF-kappa B mediated signaling, with upregulation of numerous innate immune related mRNAs, including IL-6 and a large group of interferon-stimulated genes. IL-6 upregulation in the absence of the ZC3H11A protein correlated with an increased NF-kappa B transcription factor binding to the IL-6 promoter and decreased IL-6 mRNA decay. The enhanced NF-kappa B signaling pathway in ZC3H11A deficient cells correlated with a defect in I kappa B alpha inhibitory mRNA and protein accumulation. Upon ZC3H11A depletion The I kappa B alpha mRNA was retained in the cell nucleus resulting in failure to maintain normal levels of the cytoplasmic I kappa B alpha mRNA and protein that is essential for its inhibitory feedback loop on NF-kappa B activity. These findings indicate towards a previously unknown mechanism of ZC3H11A in regulating the NF-kappa B pathway at the level of IkB alpha mRNA export

The incidence of Iron Deficiency Anemia in Allergic Rhinitis patients in Qena University Hospital

Background: Allergic rhinitis is a common disease of immune origin. It affects the quality of life of patients negatively. Objectives: To evaluate the changes in iron profile in allergic rhinitis patients. Patients and methods: This study was conducted on thirty patients with allergic rhinitis. All of the participants were subjected to clinical evaluation and the following investigations: Complete blood picture, Serum ferritin, Serum iron and total iron binding capacity (TIBC) and IgE. Visual analogue scale (VAS) score was used to measure the severity of allergic rhinitis. Results: Among the studied patients, there were 18 males (60%) and 12 females (40%), the mean age of studied patients was 11.3 ± 4.2 (SD) years with mean onset age of 4.6 ± 3.01(SD) years and mean duration of disease of 6.7 ± 2.9 years. There were 8 patients (26.7%) with positive family history in the studied patients. The incidence of iron deficiency and iron deficiency anemia was significantly higher in children with severe allergic rhinitis compared with mild cases. Also we found statistically significant difference (p-value = 0.037) between mild, moderate & severe cases of allergic rhinitis as regard Hb, MCH, HCT, ferritin, serum iron and TIBC. A statistically significant difference (p-value = 0.015) was noted between mild, moderate & severe cases as regard IgE. Serum IgE is correlated with the severity of allergic rhinitis in children. Conclusion: Prevalence of iron deficiency anemia in pediatric patients with allergic rhinitis is higher than in patients without atopic disease. Iron deficiency anemia increases markedly with severity of allergic rhinitis. Serum IgE is correlated with the severity of allergic rhinitis in children
