Novel Prosopis juliflora leaf ethanolic extract as natural antimicrobial agent against food spoiling microorganisms
( Nature Research , 2021 , Article)Fresh produces spoilage is a worldwide concern that accompany the global increase in food demand. Adverse human health and environmental effects of commercial spoilage control agents are major public concern. In this study, ... -
Novel Prosopis juliflora leaf ethanolic extract coating for extending postharvest shelf-life of strawberries
( Elsevier , 2022 , Article)Strawberry (Fragaria x ananassa) is a rich source of nutrients, minerals, and antioxidants including vitamin C. Its susceptibility to mechanical injuries, dehydration, and fungal infections make its postharvest shelf-life ... -
Fungal food spoilage of supermarkets' displayed fruits
( Veterinary World , 2019 , Article)Background and Aim: Post-harvest fungal infection of fruits and vegetables is mainly caused by fungal pathogens that can be harmful to both human and animals as they produce mycotoxins, post-harvest diseases in fruits and ... -
Halophytes as important sources of antioxidants and anti-cholinesterase compounds
( Springer International Publishing , 2021 , Book chapter)Halophytes are plants adapted to high salinity, and they are common in many places around the world where environmental conditions are inconvenient for the growth of conventional plants. Normally, plants exposed to harsh ... -
Application of Balanced Acceptance Sampling to an Intertidal Survey
( De Gruyter Open Ltd , 2017 , Article)In ecological studies, the population of interest is often spread over a large area. In these studies, obtaining a sample with good spatial coverage is an important feature in the design of a survey. In most cases adjacent, ... -
Review of Progress and Prospects in Research on Enzymatic and Non- Enzymatic Biofuel Cells; Specific Emphasis on 2D Nanomaterials
( Bentham Science Publishers , 2022 , Article)Energy generation from renewable sources and effective management are two critical challenges for sustainable development. Biofuel Cells (BFCs) provide an elegant solution by combining these two tasks. BFCs are defined by ... -
Pharmacist Role in Hypertension Management in the Community Setting: Questionnaire Development, Validation, and Application
( Dove Press Ltd , 2023 , Article)Background: Hypertension is a leading cause of mortality and morbidity globally. Pharmacists can play a substantial role in decreasing the burden of the disease. Purpose: The primary aim of this study was to develop and ... -
Assessment of Broadly Reactive Responses in Patients With MERS-CoV Infection and SARS-CoV-2 Vaccination
( American Medical Association , 2023 , Article)Importance: In the ongoing COVID-19 pandemic, there remain unanswered questions regarding the nature and importance of the humoral immune response against other coronaviruses. Although coinfection of the Middle East ... -
Follow up and comparative assessment of IgG, IgA, and neutralizing antibody responses to SARS-CoV-2 between mRNA-vaccinated naïve and unvaccinated naturally infected individuals over 10 months
( Elsevier , 2023 , Article)BackgroundEvidence on the effectiveness of vaccination-induced immunity compared to SARS-CoV-2 natural immunity is warranted to inform vaccination recommendations. AimIn this study, we aimed to conduct a comparative ... -
CAMP induces adhesion of microvascular smooth muscle cells to fibronectin via an epac-mediated but PKA-independent mechanism
( Cell Physiol Biochem Press , 2012 , Article)Background/Aims: Vascular smooth muscle cells (VSMCs) play important roles, both in physiologic and pathophysiologic processes. Adhesion of these cells is critical for their proper functioning, especially in resistance-sized ... -
