Exercise training increases telomerase reverse transcriptase gene expression and telomerase activity: A systematic review and meta-analysis
( Elsevier , 2021 , Article Review)Telomeres protect genomic stability and shortening is one of the hallmarks of ageing. Telomerase reverse transcriptase (TERT) is the major protein component of telomerase, which elongates telomeres. Given that short telomeres ... -
Exergames to Improve Postural Balance in Older People with Dementia
( Human Kinetics, Inc. , 2016 , Conference Paper)The focus of the study concerns the well-documented increased risk of falling in older adults that can lead sometimes to fatal consequences. Improving posture and motor skills is central to preventing falls. Further ... -
Existence and approximation results for SKC mappings in CAT(0) spaces
( Springer International Publishing , 2014 , Article)Recently, Karap?nar and Tas (Comput. Math. Appl. 61:3370-3380, 2011) extended the class of Suzuki-generalized nonexpansive mappings to the class of SKC mappings. In this paper, we investigate SKC mappings to get a criterion ... -
Existence of a tripled coincidence point in ordered Gb-metric spaces and applications to a system of integral equations
( Springer , 2013 , Article)In this paper, tripled coincidence points of mappings satisfying some nonlinear contractive conditions in the framework of partially ordered G b-metric spaces are obtained. Our results extend the results of Aydi et al. ... -
Expanding or shrinking? range shifts in wild ungulates under climate change in Pamir-Karakoram mountains, Pakistan
( Public Library of Science , 2021 , Article)Climate change is expected to impact a large number of organisms in many ecosystems, including several threatened mammals. A better understanding of climate impacts on species can make conservation efforts more effective. ... -
Expansion of fisheries in Qatar (1980-1992): Growth of an artisanal fleet and closure of a trawling company
( Elsevier Science B. V. , 1995 , Article)Total fish landings in Qatar increased from 1736 t per annum in 1980 to 7845 t in 1992. Ninetythree percent of this growth was due to an increase in the artisanal fleet exemplified by increases in: (i) numbers of vessels ... -
Expatriate languages in Kuwait: Tension between public and private domains
( Taylor and Francis Ltd. , 2016 , Article)Following the rise of oil-based economies after the 1950s, the six Gulf Cooperation Council (GCC) countries became extremely attractive to workers from other Arab countries and beyond. Initially, Arabs were a majority in ... -
