MicroRNA205: A Key Regulator of Cardiomyocyte Transition from Proliferative to Hypertrophic Growth in the Neonatal Heart
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2024 , Article)
The mammalian myocardium grows rapidly during early development due to cardiomyocyte proliferation, which later transitions to cell hypertrophy to sustain the heart’s postnatal growth. Although this cell transition in the ...
The perils of building big: Desalination sustainability and brine regulation in the Arab Gulf countries
(
Elsevier
, 2024 , Article)
Seawater desalination has become an accessible option for augmenting freshwater supplies worldwide. In the countries of the Gulf Cooperation Council (GCC), it has been practiced for decades as the main source for domestic ...
Virtual agents and flow experience: An empirical examination of AI-powered chatbots
(
Elsevier
, 2022 , Article)
The aspects that could shape customers' virtual experiences with chatbot applications are poorly understood. Therefore, this study aims to empirically examine the main factors that shape customers' virtual flow experiences ...
Symmetry analysis of the Klein-Gordon equation in Bianchi i spacetimes
(
World Scientific
, 2015 , Article)
In this work we perform the symmetry classification of the Klein-Gordon equation in Bianchi I spacetime. We apply a geometric method which relates the Lie symmetries of the Klein-Gordon equation with the conformal algebra ...
Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and reproduction
(
Elsevier B.V.
, 2022 , Article)
Estrogens, such as the 17β-estradiol (E2) and the 17α-ethinylestradiol (EE2), have been regarded as a global threat to aquatic ecosystems due to their pseudo-persistence, their high estrogenic activity and their toxicity ...
Noether symmetries and conservation laws of wave equation on static spherically symmetric spacetimes with higher symmetries
(
Elsevier
, 2014 , Article)
In Bokhari et al. (2011), the Noether symmetries of the wave equation on a general spherically symmetric spacetime metric were provided in terms of five functions of the variables t and r subject to certain differential ...
Zooplankton abundance and community structure driven by tidal currents in a Mediterranean coastal lagoon (Boughrara, Tunisia, SW Mediterranean Sea)
(
Academic Press
, 2021 , Article)
Lagoons and coastal marine zones are very productive and useful ecosystems, but they are threatened by the effects of global change and anthropogenic pressures. These effects have a negative impact on the zooplankton, ...
Unfolding jellyfish bloom dynamics along the mediterranean basin by transnational citizen science initiatives
(
MDPI AG
, 2021 , Article)
Science is addressing global societal challenges, and due to limitations in research financing, scientists are turning to the public at large to jointly tackle specific environmental issues. Citizens are therefore increasingly ...
Population dynamics and predatory impact of the alien jellyfish Aurelia solida (Cnidaria, Scyphozoa) in the Bizerte Lagoon (southwestern Mediterranean Sea)
(
Hellenic Centre for Marine Research
, 2020 , Article)
Understanding the life cycle strategies and predatory impact of alien jellyfish species is critical to mitigate the impact that these organisms may have on local populations, biodiversity, and ultimately on the functioning ...
Phytoplankton size changes and diversity loss in the southwestern Mediterranean Sea in relation to long-term hydrographic variability
(
Academic Press
, 2020 , Article)
Structural changes in plankton primary producers have large implications for food web dynamics, energy fluxes and the vertical export of biogenic particulate carbon. Here we examine phytoplankton data spanning the period ...
