The QChip1 knowledgebase and microarray for precision medicine in Qatar
( Nature Research , 2022 , Article)Risk genes for Mendelian (single-gene) disorders (SGDs) are consistent across populations, but pathogenic risk variants that cause SGDs are typically population-private. The goal was to develop "QChip1," an inexpensive ... -
Prognostic tools and candidate drugs based on plasma proteomics of patients with severe COVID-19 complications
( Nature Research , 2022 , Article)COVID-19 complications still present a huge burden on healthcare systems and warrant predictive risk models to triage patients and inform early intervention. Here, we profile 893 plasma proteins from 50 severe and 50 ... -
First characterisation of antimicrobial susceptibility and resistance of Neisseria gonorrhoeae isolates in Qatar, 2017-2020
( Public Library of Science , 2022 , Article)Limited data are available regarding antimicrobial resistance in Neisseria gonorrhoeae strains circulating in WHO Eastern Mediterranean Region (EMR). We investigated the antimicrobial susceptibility/resistance of N. ... -
Detection of Antinuclear Antibodies Targeting Intracellular Signal Transduction, Metabolism, Apoptotic Processes and Cell Death in Critical COVID-19 Patients
( Universita Cattolica del Sacro Cuore , 2022 , Article)Background and Objectives: The heterogeneity of the coronavirus disease of 2019 (COVID-19) lies within its diverse symptoms and severity, ranging from mild to lethal. Acute respiratory distress syndrome (ARDS) is a leading ... -
Statistical methods and resources for biomarker discovery using metabolomics.
( BMC , 2023 , Article Review)Metabolomics is a dynamic tool for elucidating biochemical changes in human health and disease. Metabolic profiles provide a close insight into physiological states and are highly volatile to genetic and environmental ... -
A single tube system for the detection of Mycobacterium tuberculosis DNA using gold nanoparticles based FRET assay
( Elsevier , 2017 , Article)The global combat against MTB is limited by challenges in accurate affordable detection. In this study, a rapid, affordable, single tube system for detection of unamplified MTB16s rDNA was developed. Utilizing a AuNP based ... -
Enteric pathogens modulate metabolic homeostasis in the Drosophila melanogaster host
( Elsevier , 2022 , Article)On quotidian basis, living beings work out an armistice with their microbial flora and a scuffle with invading pathogens to maintain a normal state of health. Although producing virulence factors and escaping the host's ... -
Molecular epidemiology, genetic diversity, and vaccine availability of viral acute gastroenteritis in the middle East and North Africa (MENA) region
( Elsevier , 2022 , Article)Acute gastroenteritis is the cause of considerable mortality and morbidity worldwide, particularly among children under five years in underdeveloped countries. Most acute gastroenteritis (AGE) cases are attributed to viral ... -
Comparative analysis of within-host diversity among vaccinated COVID-19 patients infected with different SARS-CoV-2 variants
( Elsevier , 2022 , Article)Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a rapidly evolving RNA virus that mutates within hosts and exists as viral quasispecies. Here, we evaluated the within-host diversity among vaccinated and ... -
Assessment of calcified aortic valve leaflet deformations and blood flow dynamics using fluid-structure interaction modeling
( Elsevier , 2017 , Article)Aortic valve diseases are among the most common cardiovascular defects. Since a non-functioning valve results in disturbed blood flow conditions, the diagnosis of such defects is based on identification of stenosis via ... -
Will influenza A(H3N8) cause a major public health threat?
