Spanlastic-laden in situ gel as a promising approach for ocular delivery of Levofloxacin: In-vitro characterization, microbiological assessment, corneal permeability and in-vivo study.

The objective of this study was to encapsulate the antibacterial drug levofloxacin hemihydrate (LF) into spanlastics (SLs) followed by incorporation into gelrite in situ gel to enhance its antibacterial activity and sustain ocular delivery.

Molecular characterization of gut microbial structure and diversity associated with colorectal cancer patients in Egypt.

Introduction: a large number of microbes colonizing the gut are highly diverse and complex in their structure, as this complex structure of gut microbiota acts as an indicator of a diseased state. Recently, there is a need for improved biomarkers for colorectal cancer (CRC) and advanced adenoma. Among the CRC associated organisms, bacteria are the most common causes of serious disease and deaths.

A novel therapeutic combination of dapagliflozin, Lactobacillus and crocin attenuates diabetic cardiomyopathy in rats: Role of oxidative stress, gut microbiota, and PPARγ activation.

Aims: Diabetic cardiomyopathy is diagnosed by the development of abnormality in the structure and performance of myocardium in diabetic mellitus (DM) patients. Recent studies reported the association between altered gut microbiota and metabolic disorders like diabetes and cardiovascular diseases. Here, we aimed to investigate the gut-heart axis in an experimental animal model where we developed a novel therapeutic combination of dapagliflozin, crocin prebiotic and Lactobacilli probiotic to correct induced diabetic cardiomyopathy.

Early forecasting of COVID-19 case progression with hematological and biochemical parameters of patients in Egypt.

The therapeutic role of lactobacillus and montelukast in combination with metformin in diabetes mellitus complications through modulation of gut microbiota and suppression of oxidative stress.

Male reproductive dysfunction is one of the overlooked findings of diabetes mellitus (DM) that deserves greater scientific attention. This study is designed to explore the therapeutic potential of metformin and montelukast, in combination with Lactobacillus, for modulation of intestinal flora and suppression of oxidative stress in testicular and liver damage in diabetic male rats. A DM model was induced by streptozotocin (STZ)which caused functional, biochemical, and inflammatory injuries to the testicular and liver tissues.

Molecular Characterization of Hepatitis C Virus for Developed Antiviral Agents Resistance Mutations and New Insights into in-silico Prediction Studies.

Background: Identification and characterization of developed antiviral drug resistance mutations are key to the success of antiviral therapies against hepatitis C virus (HCV), which remains a worldwide highly prevalent pathogenic disease. Although most studies focus on HCV genotypes 1, 2 or 3, the investigation of drug resistance in HCV genotype 4, predominant in North Africa, is especially significant in Egypt.

Methods: We performed mutational and genotypic analysis of the untranslated region (UTR) and nonstructural protein 5B (NS5B) drug resistance-associated regions of HCV for patients in the surrounding villages of Mansoura city, who were not responding to different antiviral treatments (sofosbuvir (SOF), ribavirin, and interferon).

Ocular Inserts of Voriconazole-Loaded Proniosomal Gels: Formulation, Evaluation and Microbiological Studies.

Background: Voriconazole (VRC) is a triazole broad spectrum antifungal drug, used in the management of versatile fungal infections, particularly fungal keratitis. The obligatory use of niosomal delivery of VRC may reduce the frequency of dosing intervals resulting from its short biological half time and consequently improve patient compliance.

Methods: VRC loaded proniosomes (VRC-PNs) were set by the coacervation technique and completely characterized.
