Antioxidative Stress Metabolic Pathways in Moderately Active Individuals
( MDPI , 2023 , Article)Physical activity (PA) is known to have beneficial effects on health, primarily through its antioxidative stress properties. However, the specific metabolic pathways that underlie these effects are not fully understood. ... -
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 ... -
Bacterial indoor air contaminations in hospitals in MENA region: a systematic review
( Taylor and Francis , 2022 , Article Review)Poor indoor air quality in healthcare settings has been tied with the increase in hospital-acquired infections. Thus, this systematic review was conducted to assess the levels and compositions of bacteria in indoor hospital ... -
Epidemiology of SARS-CoV2 in Qatar's primary care population aged 10 years and above
( BMC , 2021 , Article)There is an urgent need to elucidate the epidemiology of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) and characterize its potential impact. Investing in characterising the SARS-CoV2 will help plan and ... -
Identification of potential natural inhibitors of the receptor-binding domain of the SARS-CoV-2 spike protein using a computational docking approach
( Hamad Bin Khalifa University Press , 2021 , Article)The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the only zoonotic-origin CoV to reach the pandemic stage, to which neither an effective vaccine nor a specific therapy is available. The spike ... -
Identification of potential natural inhibitors of the receptor-binding domain of the SARS-CoV-2 spike protein using a computational docking approach
( HBKU Press , 2021 , Article)Background: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the only zoonotic-origin CoV to reach the pandemic stage, to which neither an effective vaccine nor a specific therapy is available. The ... -
Immune Modulatory Effects of Vitamin D on Viral Infections.
( MDPI , 2020 , Article)Viral infections have been a cause of mortality for several centuries and continue to endanger the lives of many, specifically of the younger population. Vitamin D has long been recognized as a crucial element to the ... -
Impact of Moderate Physical Activity on Inflammatory Markers and Telomere Length in Sedentary and Moderately Active Individuals with Varied Insulin Sensitivity
( Dove Medical Press , 2023 , Article)Introduction: Physical activity-associated immune response plays a crucial role in the aging process. This study aimed to determine the impact of short-term moderate physical activity on cytokine levels, oxidative stress ... -
The impact of pre-existing immunity on the emergence of within-host immune-escape mutations in Omicron lineages
( Microbiology Society , 2025 , Article)The Omicron variant of SARS-CoV-2 circulating amongst highly immunized populations is anticipated to induce immunological pressures, potentially compromising existing immunity. This study investigates vaccine-induced ... -
In silico virtual screening of lead compounds for major antigenic sites in respiratory syncytial virus fusion protein.
( Springer , 2021 , Article)Human respiratory syncytial virus (RSV) is a leading ubiquitous respiratory pathogen in newborn infants, young children, and the elderly, with no vaccine available to date. The viral fusion glycoprotein (RSV F) plays an ... -
Influenza prevalence and vaccine efficacy among diabetic patients in Qatar
( Elsevier , 2023 , Article)Seasonal influenza viruses may lead to severe illness and mortality in patients with comorbidities, including Diabetes Mellitus (DM). Vaccination against influenza in DM patients may reduce influenza incidence and severity. ... -
