Baroreflex Sensitivity, Cardiac and Kidney Remodeling and Deterioration in Vasoactive Substances Content in Blood in Experimental Model of Renovascular Hypertension. Action of Natural Flavone, Luteolin
Abstract:
This study aimed to analyze pharmacological actions of phenolic compound luteolin on the renal and cardiac hypertrophy, blood pressure (BP), baroreflex sensitivity (BRS), levels of epoxyeicosatrienoic acids (EETs), prostaglandin E-2 (PGE-2) and endothelin-1 (E1) in plasma in the 2 kidney - 1 clip (2K-1C) model of renovascular hypertension (RVH). All animals, were randomized into 2 groups: control (normal) I - sham-operated, II- RVH male Wistar rats, which after 4 weeks of surgical intervention secondly randomized to control II group, treated 0.1% dimethyl sulphoxide (DMSO) and main group - with luteolin in 15 DMSO, 3 mg/kg body weight, intraperitonially, during 2 weeks. ET-1, EETs and PGE2 levels investigated in carotid artery blood plasma and analyzed using ELISA kits. All data statistically analyzed using the SPSS-10.0 program. In RVH rats BP increased by 32%, cardiac and right kidney hypertrophy and ...
Detection of carbapenem resistance mechanisms among Avian Pathogenic Escherichia coli (APEC) isolated from broiler chickens
Abstract:
The emergence and spread of carbapenem-resistant gram-negative bacteria pose a serious threat to human health. Currently, little is known about the molecular mechanisms underlying carbapenem -resistance and their prevalence among APEC in Egypt. The aim of this study was to detect APEC in clinically diseased broiler chickens collected from broilers farms located at Dakahalia governorates, asses their virulence –associated genes, detect the antimicrobial susceptibility of recovered isolates and to detect genes encoding carbapenemase resistant. A total of 100 organ tissue samples subjected to conventional culture technique for isolation of E. coli. The confirmed E. coli were subjected to disc diffusion method for detection their susceptibility to antimicrobials. Polymerase chain reaction (PCR) was...
Spontaneous Subgaleal Hemorrhage in a Child with Autism
Abstract:
Severe ascorbic acid (Vitamin C) deficiency, commonly known as “scurvy,” continues to be a problem in malnourished populations across the world but is relatively rare in the United States. Early features of this condition include general weakness, fatigue, and aching limbs. An extremely rare and late feature of this condition is subgaleal hemorrhage. Scurvy has such a low prevalence in First World countries that it is often misdiagnosed or not diagnosed at all. The subject in this case report presented acutely and is one of few to involve a subgaleal hemorrhage to be documented in medical literature to date. Laboratory studies and clinical improvement through treatment established the diagnosis. Ascorbic acid deficiency should be considered when evaluating children with poor nutrition despite socioeconomic status, living conditions, or access to health care. This case also reminds us that neurodivergent chil...
A Tandem of Rare Complications Due to Stent Infection
Abstract:
This report details sequential rare complications arising from a vascular stent infection. Clinical course, microbiology, and imaging are outlined, with emphasis on early recognition and multidisciplinary management. Lessons for device surveillance and antimicrobial stewardship are highlighted.
Capturing School Data on Bullying and Harassment is Just the Beginning of the Story, Using the Data Can Provide Us with an Ending
Abstract:
This article argues that collecting school data on bullying and harassment must be paired with transparent analysis and targeted interventions. It outlines governance, feedback loops, and practical steps to translate data into safer environments.
Evaluation of Growth and some Growth Analysis Components in Sugar beet Genotypes Grown under Low Nitrogen Fertilizer Levels in Khartoum State- Sudan
Abstract:
This investigation was carried out at the Demonstration Farm of the College of Agriculture- University of Bahri during 2018/2019 winter season to evaluate growth (morphological) and growth analysis (physiological) components in some sugar beet (
Time Series Analysis and Prediction of COVID-19 pandemic using Dynamic Harmonic Regression Models
Abstract:
Rapidly spreading Covid-19 virus and its variants, especially in metropoli- tan areas around the world, became a major health public concern. The tendency of Covid-19 pandemic and statistical modelling represent an urgent challenge in the United States for which there are few solutions. In this paper, we demonstrate com- bining Fourier terms for capturing seasonality with ARIMA errors and other dynamics in the data. Therefore, we have analyzed 156 weeks COVID-19 dataset on national level using Dynamic Harmonic Regression model, including simulation analysis and ac- curacy improvement from 2020 to 2023. Most importantly, we provide a new advanced pathways which may serve as targets for developing new solutions and approaches.
Seasonal ARIMA model for Covid-19 pandemic Prediction in the United States
Abstract:
The COVID-19 pandemic has had a profound impact on global health and economies. The pandemic continues to spread and accurate forecasting of its spread is essential for the effective management of healthcare systems and the development of effective policies. The development of forecasting models for COVID-19 has become increasingly important as the pandemic continues to evolve. In this paper, we will summarize the Covid-19 pandemic in the United States state by state. And then, we utilize the temporal data of coronavirus spread from January 18, 2020 to January 29, 2023. Finally, we model the evolution of the COVID-19 outbreak and perform prediction using ARIMA and time series forecasting models on some selected states.
Statistical Study on the Impact of Computer-use on Child-health in the Arab-community
Abstract:
United States of America (USA), Australia, and Canada recommending children computer-use should be imperfect. It obligated a strong influence on children’s lives. The problem was for stuck in the computer-use for a long time per day. The goal was to follow child-health in the Arab-community to notice its influence on the child-health. The method was through a arithmetical study by sending Internet questionnaire and receiving the parents' advice. The results were in the 500 parent answers and 14 comments. The first was "You have a child up to 13 years old?"; 83.6%. The second was "Your child used a computer?"; 80.8%. The third was "Your child used the computer for a long time?"; 67.9%. The fourth was "The computer caused a health problem for your child?"; 70.3%. The fifth was "The computer caused your child mental disorder?"; 68.5%. The sixth was "The computer caused your child trouble seeing?"; 77.2%. The seventh was "The computer caused your child trouble sleep...
Experimental Study by the Plan Composite Centered Method, Modeling and Optimization of Hydrogen Production by Alkaline Electrolysis
Abstract:
A planned experimental study on the production of green hydrogen by alkaline electrolysis is carried out by the Plan Composite Centered (PCC) method. The parameters studied are the concentration of the electrolyte, the distance between electrodes, the height of the electrodes, the total supply voltage of the electrolyser, temperature, and the electrolyte type. The results show that the effect of concentration, height, voltage and temperature are positive. However, the effect of the distance between the electrodes is negative. Electrolysis with potassium hydroxide (KOH) is more efficient than with sodium hydroxide (NaOH). The second-order interactions are weak, except for the voltage-temperature interaction which is significant. The results of the experimental study conducted in this work are in agreement with previous studies. Two a polynomial modeling (with KOH and with NaOH) suitable for predicting the flow of hydrogen produced are presented. Three optimizations...
