Efficient String Edit Similarity Join Algorithm

Karam Gouda, Metwally Rashad
2017 Computing and informatics  
String similarity join is a basic and essential operation in many applications. In this paper, we investigate the problem of string similarity join with edit distance constraints. A trie-based edit similarity join framework has been proposed recently. The main advantage of existing trie-based algorithms is support for similarity join on short strings. The main problem is when joining long and distant strings. These methods generate and maintain lots of similar prefixes called active nodes which
more » ... need to be further removed in a subsequent pruning phase. With large edit distance, the number of active nodes becomes quite large. In this paper, we propose a new trie-based join algorithm called PreJoin, which improves upon current trie-based join methods. It efficiently finds all similar string pairs using a novel active-node generation method, which minimizes the number of generated active nodes by applying the pruning heuristics early in the generation process. The performance of PreJoin is scaled in two different ways: First, a dynamic reordering of the trie index is used to accelerate the search for similar string pairs. Second, a partitioning method of string space is used to improve performance on large edit distance thresholds. Experiments show that our approach is highly efficient for processing short as well as long strings, and outperforms the state-of-the-art trie-based join approaches by a factor five.

Phytochemical and molecular analyses of some Coleus cultivars cultivated in Egypt

Rashad M. Shoaib, Sami I. Ali, Sami A. Metwally, Mohamed M. Ibrahim, Kamal A. Aboud
2020 Bulletin of the National Research Centre  
Coleus (family Lamiaceae) is a popular garden ornamental plant known for its bright-colored foliage. The effective role of different plant growth regulators have been widely reported in plant cultivars (Singh A and Prasad SM Int. J. Sci. Eng. Appl. Sci. 2 (1): 1-10, (2016)). Kinetin has received great interest due to its richness in bioactive phytochemicals including polyphenolic compounds with its antioxidant activity. Molecular markers have been very helpful in enhancing our understanding of

In our study, we investigated the effect of three treatments of kinetin on the phytochemical contents of five Coleus cultivars and molecular characterization by ISSR markers. Results: The studied cultivars of Coleus revealed adequate amounts of pigments chlorophyll a (Cha), chlorophyll b (Chb), and total carotenoids (Carot) as well as phytochemical ingredients including total carbohydrates (Carb), total phenolic (TP), total flavonoids (TF), and total tannins (TT). Finger paint cultivar (C 5 ) revealed the highest values (0.266, 10.853, 11.648, and 6.722 mg/g) of Carb, TP, and TT, respectively, while the highest contents (11.814 and 11.648 mg/g) of TF were identified in Beckwhites gem species (C 2 ) and finger paint cultivar (C 5 ), respectively. Intersimple sequence repeat (ISSR) marker analysis was performed on the samples with 5 primer pairs. These bands were identified as 21 polymorphic and 18 monomorphic ones with 53.8% polymorphism. Ten unique bands were identified in the resulted ISSR profile. Conclusion: These results suggested that the effect of kinetin treatments stimulates secondary metabolites production. Also, ISSR marker is helpful for possible distinguishing, identifying, characterizing, and selection processing of Coleus cultivars.

2020 Annals of the Rheumatic Diseases  
Background:Rheumatic musculoskeletal disorders (RMSDs) are a common cause of long term pain and physical disability. In developed countries, RMSDS are a major cause of absence from work and thus have a big financial burden on the country economic status. Several studies have been published the incidence and prevalence of RMSDs in different world countries and found to be widely variable. Estimation of the extend of the problem of RMSDs in developing world, especially in rural economies will

Mean age of patients was (46.89±15.25ys). They proceeded 4 phases of World Health Organization/International League of Associations for Rheumatology community-oriented program for control of rheumatic diseases survey questionnaire WHO-ILAR Community Oriented Program for screening of rheumatic diseases. Modified Health Assessment Questionnaire (HAQ) was used to assess the disability severity. Individuals suspected to have any rheumatic diseases were subjected to full clinical examination, laboratory and radiological investigations to reach a final diagnosis. They were classified according to appropriate criteria of diagnosis of diseases.Results:A prevalence rate of RMSDs was 16.22%, more prevalence in females (10.38% vs. 5.84% for males, P=0.000). The mean age of patients with RRMSDSs were older (46.89±15.25 yrs) than healthy individuals (29.56±18.95 yrs) (P=0.0001) and with increasing age (≥45-≤ 55 yrs).The identified RMSDs were OA (8.5%), Soft tissue rheumatism (STR) (6.57%), spinal disorders (SD) (6.47%), fibromyalgia (FM) (0.60%), RA (0.30%), arthralgia (0.18%), SPAs (0.15%), Gout(0.6%), Pseudogout (0.08%), SLE (0.5%), JIA(0.03) and MCTD (0.03%). The prevalence rates for the majority of RRMSDSs were higher in females and with increasing age. About two thirds of the patients had grade II disability.Conclusion:The prevalence rate of RMSDs in a rural population ≥15years in Upper Egypt has been estimated to be 16.22%.The most prevalent RMSDs are OA, STR and SD causing the greatest burden of the disease. The predictive risk of RMSDs has to be assessed in future studies.References:[1]Majumdar A, Kumar SG, Nair D, Sujiv A.

<p>ABSTRACT<br />Objective: The goal of the present study was to examine the viability of Morus alba (M. alba) ethanolic extract in repression of obesity-associated<br />hepatic steatosis and related metabolic disorder; dyslipidemia, hyperinsulinemia, and glycemic status.<br />Methods: Adult female albino rats were randomly assigned into four groups, eight rats each as follows: Group (1) control group received standard<br />rodent diet for 24 weeks. The other three groups administered high
more » ... sterol diet for 12 weeks and served as obese group, M. alba-treated group,<br />and simvastatin-treated group.<br />Results: The current results showed an increment in thoracic circumference (TCX) and abdominal circumferences (AC) as well as body mass index<br />(BMI) in obese group. In addition, dyslipidemia, hyperinsulinemia, hyperglycemia, and insulin resistance have been elucidated in obese group.<br />Moreover, hepatic malondialdehyde (MDA), nitric oxide (NO), serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin<br />values were significantly increased in obese groups versus control group. On the other hand, administration of ethanolic extract of Morus alba or<br />simvastatin could significantly lessen BMI and in addition to improve dyslipidemia in obese group. Glucose, insulin levels, and insulin resistance value<br />in serum samples demonstrated a significant reduction in obese group upon treatment with M. alba ethanolic extract or simvastatin. Furthermore,<br />noticeable depletion in hepatic MDA, NO contents, serum ALT, AST activities, and serum bilirubin level was recorded as a result of treatment with<br />either ethanolic extract of M. alba or simvastatin. Histopathological examination of liver tissue showed ballooning degeneration in the hepatocytes<br />(hepatic steatosis) associated with inflammatory cells penetration in portal zone in obese group. Meanwhile, the treatment of obese groups with<br />ethanolic extract of M. alba or simvastatin was found to restore the structural organization of the liver.<br />Conclusion: The present findings provide a novel aspect for understanding of the role of M. alba against obesity-associated liver diseases and related<br />metabolic disorder. The mechanisms underlying these effects seem to depend on the hypolipidemic potential, anti-inflammatory property, and<br />antioxidant activity of its phytochemicals.<br />Keywords: Obesity, Morus alba, Dyslipidemia, Hyperinsulinemia, Hyperglycemia, Hepatic steatosis.</p>

BACKGROUND: The risk of obesity among autism spectrum disorder (ASD) children is high which could be related to a disorder in their metabolism. Brain derived neurotrophic factor (BDNF) is involved in metabolic control, language behavior, and intellectual development. Serotonin has a role in satiety and energy expenditure. AIM: Therefore, the aim of this study was to measure the serum levels of BDNF and serotonin in obese compared to non-obese ASD children. The influence of obesity on ASD
more » ... y, intellectual, and language development was also investigated. METHODS: The study included 60 autistic children (Group I: 30 ASD children with obesity and Group II: 30 ASD children without obesity). The serum BDNF and serotonin levels were estimated by ELISA and by high-performance liquid chromatography. RESULTS: All participants manifested delayed language development. Almost all of them had intellectual disability. The difference between groups regarding ASD severity, language, and intellectual development was non-significant. However, BDNF level in obese group was less than that in the other group while serotonin was higher in the obese group with significant statistical difference. CONCLUSION: The difference between the groups regarding the levels of BDNF and serotonin, which are involved in the brain development, could be related to obesity. The influence of obesity on ASD severity, intellectual, and language development of ASD children was not distinctive in the participants. The influence of such markers on ASD severity and cognitive performance needs further investigations.

Background The presented evidence-based clinical practice guideline (CPG) is proposed as a National CPG using an evidence-based and formal CPG adaptation methodology. The purpose of this study was to adapt the international CPGs' recommendations for children with bronchiolitis to suit the healthcare system in the Egyptian context. This CPG, 'diagnosis, treatment, and prevention of Bronchiolitis', applies to children from 1 through 23 months of age. Other exclusions are noted. The quality of

This study is part of a larger collaborative initiative with the faculty staff of pediatric departments of 15 Egyptian universities and a national research center to formulate a national Committee (EPG) that aims to define the topics of, assign authors to, and assist in the adaptation of pediatric evidence-based CPGs according to a national strategic plan. The committee is guided by a formal CPG adaptation methodology: the 'Adapted ADAPTE'. Results The Bronchiolitis Guideline Adaptation Group (BGAG) reviewed the results of the AGREE II assessment and decided to adapt mainly the Australasian (PREDICT) CPG and for the questions not answered in PREDICT we adapted the relevant recommendations from the American Academy of Pediatrics (AAP) CPG. Seven implementation tools were included: a care pathway for assessment of severity, a clinical algorithm for treatment of acute bronchiolitis in the emergency room, a separate flowchart for assessing babies with bronchiolitis, a power point slide presentation lecture for treatment of acute bronchiolitis, patient information in Arabic, a clinical score (Modified Tal Score) for prediction of bronchiolitis severity, and the criteria for admission and discharge in the hospital. A comprehensive set of multifaceted CPG implementation strategies was provided for the clinicians, patients, nurses, and other relevant stakeholders contextualized to the national settings Conclusion Our experience with this adaptation methodology provides useful insight into its utilization on a national level in Egypt. The BGAG recommended the next review of this adapted CPG to be after 3 years from its publication (i.e., 2022) after checking for updates in the original CPG.
