The purpose of this article is to study gloomy eyelet (GE) inside the cell nucleus by using models warp drive hydro (WDH), swinging spring, Rankine, co-moving reference frame, and Poincare. beat wave frequency (ω) blood pressure on vessel spring (Ω) DNA coincide together Rankine model. In case, it leads appearing as a sudden drop an accelerated cavity in medium (WDH) transient conditions, vorte...

Two variants of biologically inspired cell model, namely eukaryotic (containing a nucleus) and prokaryotic(without a nucleus) are compared in this research. Experiments are designed to provide an understanding of how the evolved regulation of protein transport to and from the nucleus of the eukaryotic type cell gives rise to complex temporal dynamics that are not achievable in a prokaryoticcell...

UNLABELLED Several radionuclides used in medical imaging emit Auger electrons, which, depending on the targeting strategy, either may be exploited for therapeutic purposes or may contribute to an unintentional mean absorbed dose burden. In this study, the virtues of 12 Auger electron-emitting radionuclides were evaluated in terms of cellular S values in concentric and eccentric cell-nucleus arr...

The way in which the nucleus experiences mechanical forces has important implications for understanding mechanotransduction. Knowledge of nuclear material properties and, specifically, their relationship to the properties of the bulk cell can help determine if the nucleus directly experiences mechanical loads, or if it is a signal transduction mechanism secondary to cell membrane deformation th...

Introduction: Atherosclerosis is one of the leading causes of cardiovascular disease. Following endothelial damage and platelet aggregation in that area and the recruitment of monocytes and their conversion to macrophages, LDL gradually accumulates under the endothelial artery wall and gradually oxidized and convert to oxi-LDL. By swallowing it, the macrophages turn into foam cell and then athe...

In mammals and plants, the cell nucleus is organized in dynamic macromolecular domains involved in DNA and RNA metabolism. These domains can be visualized by light and electron microscopy and their composition analyzed by using several cytochemical approaches. They are composed of chromatin or ribonucleoprotein structures as interchromatin and perichromatin fibers and granules, coiled bodies, a...
