Abstract:
Silicon is a critical element for diatom growth; however our understanding of the molecular mechanisms involved in intracellular silicon responses are limited. In this study, an iTRAQ-LC&ndash;MS/MS quantitative proteomic approach was coupled with an established synchrony technique to reveal the global metabolic silicon-response in the model diatom <em>Thalassiosira pseudonana</em> subject to silicon starvation and readdition. Four samples, which corresponded to the time of silicon starvation, girdle band synthesis, valve formation, and right after daughter cell separation (0, 1, 5, 7 h), were

Abstract:
Silicon is a quasi-essential trace nutrient for plant growth and is frequently employed to remediate soils of heavy metal pollution in agriculture. However, silicon’s role and mechanism in reducing heavy metal toxicity have not been well understood, especially for multi-heavy metals such as cadmium, zinc, lead, and arsenic (usually treated as a heavy metal). In this study, the effects of different silicon-rich materials (silicate, rice husk biochar (RHB), and RHB + bentonite) on growth trait, antioxidant response, heavy metal accumulation, and distribution of wheat grown in two soils polluted

Abstract:
Endothelial cells are subjected to shear stresses by blood flow, normal stresses by blood pressure, and stretch by vessel expansion. These forces are known to induce secretions of several vasoactive substances probably via internal calcium mobilization (R. F. Furchgott. Circ. Res. 53: 557-573, 1983; M. J. Peach, A. L. Loeb, H. A. Singer, and J. Saye. Hypertension Dallas 7, Suppl. I: I-94-I-100, 1985).

Abstract:
Background/Aims: Osteocytes can sense and respond to extracellular stimuli, including biochemical factors throughout the cell body, dendritic processes, and cilia bending. However, further exploration is required of osteocyte function in response to substrate stiffness, an important passive mechanical cue at the interface between osteocytes and the extracellular matrix, and the deep bio-mechanism in osteocytes involving mechanosensing of cell behavior. Methods: We fabricated silicon-based elastomer polydimethylsiloxane substrates with different stiffnesses but with the same surface topologies.

Abstract:
Ultrastructural changes in the cell envelope of the yeast Yarrowia lipolytica as a stress response were examined using electron microscopy. The formation of new cellular surface structures, including membrane vesicles, pore channels, and wall surface globules, were shown for the first time under conditions of oxidative (endogenous and exogenous) or thermal stress. This demonstrates once again that under stress conditions the microorganisms reveal properties previously unknown for them. Particularly noteworthy is the accumulation of silicon in the surface globules, which was revealed by X-ray m

Abstract:
Fluorescent silicon nanoparticles (SiNPs), resembling a typical zero-dimensional silicon nanomaterial, have shown great potential in a wide range of biological and biomedical applications. However, information regarding the toxicity of this material in live organisms is still very scarce. In this study, we utilized Caenorhabditis elegans (C. elegans), a simple but biologically and anatomically well-described model, as a platform to systematically investigate the in vivo toxicity of SiNPs in live organisms at the whole-animal, cellular, subcellular, and molecular levels.

The perirhinal cortex is a key structure involved in memory consolidation and retrieval. In spite of the extensive anatomical studies that describe the intrinsic and extrinsic associative connections of the perirhinal cortex, the activity generated within such a network has been poorly investigated. We describe here the pattern of synaptic interactions that subtend the responses evoked in area 36 of the perirhinal cortex by neocortical and local stimulation. The experiments were carried out in the in vitro isolated guinea pig brain. The synaptic perirhinal circuit was reconstructed by integrat

In order to evaluate the contribution of increased Ca2+ influx across the plasma-membrane in elevating cytosolic free Ca concentration on platelet activation, 45 Ca2+uptake was measured simultaneouslyby silicon-oil centrifugation method with or without 5 mM EGTA treatment.

Abstract We hypothesized an avoidance of deformation and a limit of sensitivity of cell response to the mechanical stimulus for the orientation of stress fibers in cultured cells on a silicone membrane which was subjected to a uniaxial cyclic stretch. We compared the theoretical prediction with the experimental result of stress fibers in the human umbilical vein endothelial cells under various ranges of uniaxial cyclic stretch (Takemasa et al. 1998). The results showed that the proposed hypothesis predicted the orientation of stress fibers under various ranges of cyclic stretch well.

Abstract Vascular smooth muscle cells (SMCs) in the extracellular matrix adapt to their surrounding environment in vivo with its contraction and relaxation. As blood pressure increases, the circumferential stress on the aortic wall also increases. The major components of the media are SMCs, so SMCs should regulate the vessel diameter and the mechanical balance of the aortic medial ring. Thus, it is important to clarify how external forces on SMCs are transmitted through the intracellular components. Nuclei may sense changes in the applied mechanical stretch via stress fibers (SFs) or focal adh

Abstract:
Proteins are important macromolecules responsible for a variety of processes in living organisms. One of the most important features of proteins is their ability to respond to environmental stimuli, such as changes in intracellular metal concentration by binding metal ions, which in turns triggers structural changes within the protein that can modify its function or allow the protein to participate in a signaling pathway. One such signaling protein is the so-called neuronal calcium sensor 1 protein or NCS1, which binds Ca2+ along with other abiogenic metals such as Li+, and the metal binding r
