Abstract:

Healthy kidneys are able to filter toxins from one's blood and remove excess fluid from one's body. Kidney dialysis is a process that performs the work of kidneys that cannot function normally. During the process of hemodialysis, blood from the patient's body is run through a dialysis cartridge through very thin hollow fibers made of a semi- permeable membrane. Waste and water travel from the blood, through the pores of the membrane, and into a fluid called dialysate. We attempt to model the velocities and pressures of blood plasma and dialysate in a dialysis cartridge, as well as to model the

Abstract:

The binding interaction between specialized proteins within the extracellular matrix (ECM) and specific membrane receptors in cells are pivotal for regulating cell adhesion and migration. Current methods used to generate patterned ECM substrates for the study of migration involve technically complicated devices that are expensive and demand specialized training. Some are also not applicable to the microscopic scale relevant for cells or provide inadequate substrates for growing sensitive cells such as neurons.

Abstract:

Previous data have shown that the most prevalent, indirect plasma volume (PV) measurement technique, which utilises changes in haematocrit (Hct) and haemoglobin concentration ([Hb]), underestimates actual PV changes during immersion, when compared to a direct tracer-dilution method. An increase in the F-cell ratio (whole-body haematocrit (Hctw) to large-vessel haematocrit (Hctv) ratio) has been purported as a possible explanation, probably due to hydrostatic and thermally-mediated changes during water immersion. Previous investigators have not quantified the F-cell ratio during immersion. Ther

To examine the effect of host cell-associated antifungals on the growth of medically important molds, we exposed lung epithelial cells to antifungal agents and removed extracellular drug prior to in vitro infection.

Abstract:

Interleukin-1 (IL-1) is a multifunctional cytokine produced primarily by activated monocytes/macrophages and by a variety of other cell types. IL-1 plays an integral role in the immuno-inflammatory response of the body to a variety of stimuli including infection, trauma and other bodily injuries. Once IL-1 is released from the synthesizing cell, it acts as a hormone, initializing a variety of responses in different cells and tissues. These responses are believed to be crucial to survival and are termed acute-phase responses. NF-ÎºB is a family of dimeric transcription factors that control the

Abstract:

The effect of transferring fish from water at pH 7.0 to either more acid or more alkaline conditions was to reduce the maximum critical velocity of the fish. In water of pH 4.0, 5.0, and 10.0, the maximum critical velocity was only 54.5%, 66.5%, and 61% respectively of that recorded for fish in the water of pH 7.0. Thus, both acid and alkaline conditions in the water reduce the aerobic swimming capacity of trout. Exposure to acid conditions increased mucus secretion and this was associated with an increase in coughing and breathing frequency in resting fish. Coughing rate increased from 41/hr

Abstract:

La lumière du soleil est un bon candidat comme source propre et abondante d'énergie renouvelable. Cette source d'énergie écocompatible peut être exploitée pour répondre aux besoins croissants en énergie du monde. Plusieurs générations de cellules photovoltaïques ont été utilisées pour convertir directement la lumière solaire en énergie électrique. La troisième génération de type multijonction des cellules photovoltaïques est caractérisée par un niveau d'efficacité plus élevé que celui de tous les autres types de cellules photovoltaïques. Des dispositifs optiques, tels que des concentrateurs op

碩士<br>國防醫學院<br>生物化學研究所<br>90<br>In neuroblastoma x glioma NG108-15 cells, depletion of Ca2+ stores by thapsigargin caused an increase of the cytosolic Ca2+ concentration ([Ca2+]i), activation of caspase-3 and cell death. To characterize the relationship among [Ca2+]i increase, caspase-3 activation and cell death, we determine the effect of caspase-3 inhibitor (DEVD-CHO) and Ca2+ chelator (BAPTA) on thapsigargin-induced cell death in NG108-15 cells. Cell death was quantified by counting the percent of cells with DNA fragmentation

碩士<br>國立成功大學<br>工程科學系碩博士班<br>97<br>In this study, the Polydimethylsilcoxane (PDMS) concentration gradient microfluidic chip and PDMS stamp are fabricated by MEMS, casting molding, and microimprinting technology. The chip is used to research optimizing concentration of endothelial cells on glucose concentration gradient. The experiment strategy is based on a microfluidic network to generate a concentration gradient in solution, and observes the effect of concentration gradient in different flow rates. Besides, it combines micropatterns that cell adhesion space width with 300 μm and gap with 200
