Population immunity of natural infection, primary-series vaccination, and booster vaccination in Qatar during the COVID-19 pandemic: an observational study
( Elsevier , 2023 , Article)BackgroundWaning of natural infection protection and vaccine protection highlight the need to evaluate changes in population immunity over time. Population immunity of previous SARS-CoV-2 infection or of COVID-19 vaccination ... -
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 ... -
Blockchain Technology for Intelligent Transportation Systems: A Systematic Literature Review
( Institute of Electrical and Electronics Engineers Inc. , 2022 , Other)The use of Blockchain technology has recently become widespread. It has emerged as an essential tool in various academic and industrial fields, such as healthcare, transportation, finance, cybersecurity, and supply chain ... -
Privacy-preserving federated learning cyber-threat detection for intelligent transport systems with blockchain-based security
( John Wiley and Sons Inc , 2022 , Article)Artificial intelligence (AI) techniques implemented at a large scale in intelligent transport systems (ITS), have considerably enhanced the vehicles' autonomous behaviour in making independent decisions about cyber threats, ... -
Motivation, preference, socioeconomic, and building features: New paradigm of analyzing electricity consumption in residential buildings
( Elsevier , 2022 , Article)In strategic energy planning, human-oriented factors are uncertain and lead to unpredictable challenges. Thus, decision-makers must contextualize the target society to address these uncertainties. More precisely, uncertainties ... -
Cyclic AMP-Rap1A signaling mediates cell surface translocation of microvascular smooth muscle α2C-adrenoceptors through the actin-binding protein filamin-2
( American Physiological Society , 2013 , Article)The second messenger cyclic AMP (cAMP) plays a vital role in vascular physiology, including vasodilation of large blood vessels. We recently demonstrated cAMP activation of Epac-Rap1A and RhoA-Rho-associated kinase ... -
Thymus vulgaris (Thyme) inhibits proliferation, adhesion, migration, and invasion of human colorectal cancer cells
( Mary Ann Liebert Inc. , 2015 , Article)Colorectal cancer (CRC) remains one of the most common malignancies and a leading cause of cancer-related deaths. Its prognosis remains poor for patients with several grades of this disease. This underscores the need for ... -
Salinomycin induces apoptosis and senescence in breast cancer: Upregulation of p21, downregulation of survivin and histone H3 and H4 hyperacetylation
( Elsevier , 2013 , Article)Background In the present study, we investigated the effect of Salinomycin on the survival of three human breast cancer cell lines MCF-7, T47D and MDA-MB-231 grown in adherent culture conditions. Methods Cell viability ... -
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 ... -
Cyclic AMP-Rap1A signaling activates RhoA to induce α2c-adrenoceptor translocation to the cell surface of microvascular smooth muscle cells
( American Physiological Society , 2012 , Article)Intracellular signaling by the second messenger cyclic AMP (cAMP) activates the Ras-related small GTPase Rap1 through the guanine exchange factor Epac. This activation leads to effector protein interactions, activation, ... -
Anti-atherosclerotic plants which modulate the phenotype of vascular smooth muscle cells
( Elsevier , 2016 , Article)Background: Cardiovascular disease (CVD) remains the leading cause of global death, with atherosclerosis being a major contributor to this mortality. Several mechanisms are implicated in the pathogenesis of this disease. ... -
Determination of vascular reactivity of middle cerebral arteries from stroke and spinal cord injury animal models using pressure myography
( Humana Press Inc. , 2016 , Book chapter)Stroke and other neurovascular derangements are main causes of global death. They, along with spinal cord injuries, are responsible for being the principal cause of disability due to neurological and cognitive problems. ... -
The impact of COVID-19 pandemic on electricity consumption and electricity demand forecasting accuracy: Empirical evidence from the state of Qatar
( Elsevier Ltd , 2022 , Article)The goal of this study is to use machine-learning (ML) techniques and empirical big data to examine the influence of the COVID-19 pandemic on electricity usage and electricity demand forecasting accuracy in buildings in ... -
Robust index-tracking and enhanced index-tracking in portfolio optimization
( Ascociacion Internacional de Economia Aplicada , 2020 , Article)We study index-tracking and enhanced index-tracking problems in portfolio optimization under interval uncertainty for returns and covariance matrix. The proposed robust counterparts for both models are in the form of second ... -
A hybrid LQP alternating direction method for solving variational inequality problems with separable structure
( Natural Sciences Publishing Co. , 2015 , Article)In this paper, we presented a logarithmic-quadratic proximal alternating direction method for structured variational inequalities. The method generates the new iterate by searching the optimal step size along the descent ... -
Entropy-Like Minimization Methods Based on Modified Proximal Point Algorithm
