The role of intestinal ultrasound with colour Doppler in predicting the response to biologic therapy in inflammatory bowel disease patients.

Introduction: Inflammatory bowel disease patients are exposed to frequent procedures and hospital admissions as well as recurrent need for radiological examinations with a high risk of exposure to radiation and contrast.

Aim: Our objective was to evaluate the role of a combination of both intestinal ultrasound (IUS) and colour Doppler with different parameters for monitoring changes in inflammation over time and to reveal their potential role in the assessment of response to biologic therapy in inflammatory bowel disease (IBD) patients.

Material And Methods: Before the induction of biological therapy, IUS together with colour Doppler of the intestine was conducted.

Isolation and Characterization of Strains from Egyptian Mangroves: Exploring Their Endophytic Potential in Maize for Biological Control of .

The widespread use of pesticides to manage has led to significant challenges. This insect has developed resistance to 47 active insecticide ingredients. Therefore, endophytic entomopathogenic bacteria have been explored as an alternative pest management strategy, offering the potential to reduce reliance on chemical pesticides.

Antifungal, antiaflatoxigenic, and cytotoxic properties of bioactive secondary metabolites derived from Bacillus species.

Aflatoxins (AFs) are hazardous carcinogens and mutagens produced by some molds, particularly Aspergillus spp. Therefore, the purpose of this study was to isolate and identify endophytic bacteria, extract and characterize their bioactive metabolites, and evaluate their antifungal, antiaflatoxigenic, and cytotoxic efficacy against brine shrimp (Artemia salina) and hepatocellular carcinoma (HepG2). Among the 36 bacterial strains isolated, ten bacterial isolates showed high antifungal activity, and thus were identified using biochemical parameters and MALDI-TOF MS.

Extraction and characterization of bioactive secondary metabolites from lactic acid bacteria and evaluating their antifungal and antiaflatoxigenic activity.

Aflatoxins are toxic carcinogens and mutagens formed by some moulds, specifically spp. Therefore, this study aimed to extract and identify bioactive secondary metabolites from species, to evaluate their efficacy in reducing fungal growth and aflatoxin production and to investigate their toxicity. The bioactive secondary metabolites of species showed variable degrees of antifungal activity, whereas ethyl acetate extract No.

Potential synergistic effect of Alhagi graecorum ethanolic extract with two conventional food preservatives against some foodborne pathogens.

The present study aims to screen the anti-bacterial activity and synergistic interaction of A. graecorum Boiss. ethanolic extract with two food preservatives against five strains of foodborne bacteria.

Value-Added Utilization of Citrus Peels in Improving Functional Properties and Probiotic Viability of (ABT)-Type Synbiotic Yoghurt during Cold Storage.

Citrus peel, a fruit-processing waste, is a substantial source of naturally occurring health-promoting compounds, including polyphenols, and has great potential as a dietary supplement for enhancing the functional properties of food. The present work aimed to investigate the effects of sour orange (SO), sweet orange (SWO), and lemon (LO) peels on the typical physiochemical, antioxidant, antibacterial, and probiotic properties of synbiotic yoghurt fermented by acidophilus-bifidus-thermophilus (ABT)-type cultures during cold storage (0−28 days). High-performance liquid chromatography-diode array detection (HPLC-DAD) analysis showed that the total phenolic content in the SO peel were more than 2-fold higher than that in the SWO and LO peel.

Prevalence and Predictors of Persistent Symptoms After Clearance of SARS-CoV-2 Infection: A Multicenter Study from Egypt.

Background And Aim: Little is known about the persistence of symptoms after clearance of SARS-CoV-2 infection. Our study aimed to assess persistent symptoms in COVID-19 patients after clearance of SARS-CoV-2 infection.

Methodology: A multi-center survey was conducted on first wave COVID-19 patients with confirmed SARS-CoV-2 infection.

Chemical profiling, in vitro antimicrobial and antioxidant activities of pomegranate, orange and banana peel-extracts against pathogenic microorganisms.

Background: The use of natural preservatives became of great interest; good examples of these natural preservation agents are plant peels. The use of plant peels has dual benefits; first is their antimicrobial activity against food-borne pathogens, while the second is minimizing agro-industrial wastes.

Results: The evaluation of the antimicrobial potential of both methanolic and ethanolic extracts of three fruit peels (orange, pomegranate, and banana), against 4 Gram-positive (G), 3 Gram-negative bacteria (G), and 2 fungal strains revealed that both pomegranate peel extracts exhibited significantly higher inhibitory effect on all tested G bacteria.

Barriers for resuming endoscopy service in the context of COVID-19 pandemic: A multicenter survey from Egypt.

Background: The current coronavirus disease 2019 (COVID-19) pandemic has affected routine endoscopy service across the gastroenterology community. This led to the suspension of service provision for elective cases.

Aim: To assess the potential barriers for resuming the endoscopy service in Egypt.

Recycling of agro-wastes for Ganoderma lucidum mushroom production and Ganoderma post mushroom substrate as soil amendment.

The in vitro growth of Ganoderma mycelia on six agro-wastes namely, broad bean stalks (BBS), cotton stalk (CS), maize straw (MS), rice straw (RS), sugarcane bagasse (SCB) and wheat straw (WS) supplemented with wheat bran (WB) or corn gluten (CG) was evaluated. Among the substrates used, CS appeared best followed by SCB and RS. WB showed best supplementation for mycelial growth.

Maternal serum amyloid A level as a novel marker of primary unexplained recurrent early pregnancy loss.

Objective: To assess maternal serum amyloid A (SAA) levels among women with primary unexplained recurrent early pregnancy loss (REPL).

Methods: A prospective study was conducted among women with missed spontaneous abortion in the first trimester at Ain Shams University Maternity Hospital, Cairo, Egypt, between January 21 and December 25, 2014. Women with at least two consecutive primary unexplained REPLs and no previous live births were enrolled.

Isolation and characterization of multifunctional Streptomyces species with antimicrobial, nematicidal and phytohormone activities from marine environments in Egypt.

Different strategies have been employed for selective isolation of Streptomycetes from 20 marine samples varied in their biological nature. The recovery of Streptomycetes isolates (112) was influenced preferentially by different strategies; sediment samples were the best source of potential candidate Streptomycetes. All isolates exhibited antimicrobial activities with variable spectrum; the most promising isolates (31) were phenotypically characterized and identified as Streptomyces sp.

Identification of mosquito larvicidal bacterial strains isolated from north Sinai in Egypt.

In the present study, two of the most toxic bacterial strains of Bacillus sphaericus against mosquito were identified with the most recent genetic techniques. The PCR product profiles indicated the presence of genes encoding Bin A, Bin B and Mtx1 in all analyzed strains; they are consistent with protein profiles. The preliminary bioinformatics analysis of the binary toxin genes sequence revealed that the open reading frames had high similarities when matched with nucleotides sequence in the database of other B.
