The Impact of Age and Carbon Tetrachloride on Hepatic Polyploidy in Albino Rats (A Histological and Immunohistological Study) [PDF]
Al-Azhar International Medical JournalBackground: Polyploidy, a condition where cells contain more than two sets of homologous chromosomes, is a unique feature of hepatocytes. However, its biological significance remains incompletely understood.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues
ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Journal of Applied Toxicology, EarlyView.ABSTRACT The effects of anabolic steroid abuse on the cardiac tissue of resistance training practitioners are poorly understood. Herein, we present the histomorphometric implications of resistance training in rats treated with nandrolone decanoate, an androgenic anabolic steroid. Eighteen‐week‐old male Wistar rats (N = 32) were divided into two groups (

PLANTS, PEOPLE, PLANET, EarlyView.Field inoculation with arbuscular mycorrhizal fungi (AMF) offers a promising route to improve sustainable agriculture and food production, yet results are often variable. We investigated the mycorrhizal growth response of maize and wheat varieties recommended for farmers and found substantial variation under greenhouse conditions.

Breaking down taxonomic barriers in polyploidy research
, 2003 Polyploidy is important in the evolutionary history of plants, and it has played a crucial role in shaping the genome structures of all eukaryotes. New and rapidly improving techniques in genomics, cytogenetics and molecular ecology have resulted in a ...

The expanding implications of polyploidy [PDF]
Journal of Cell Biology, 2015 Polyploid cells, which contain more than two genome copies, occur throughout nature. Beyond well-established roles in increasing cell size/metabolic output, polyploidy can also promote nonuniform genome, transcriptome, and metabolome alterations. Polyploidy also frequently confers resistance to environmental stresses not tolerated by diploid cells ...

Polyploidy and mTOR signaling: a possible molecular link
Cell Communication and SignalingPolyploidy is typically described as the condition wherein a cell or organism has more than two complete sets of chromosomes. Occurrence of polyploidy is a naturally occurring phenomenon in the body’s development and differentiation processes under ...
